The farrowing crate is core equipment for modern pig farms, engineered for the farrowing and lactation phase. The sow zone uses stainless-steel confinement bars to prevent crushing, with adjustable width; the piglet zone has slatted flooring to keep the area dry. The hot-dip galvanized welded frame is phosphated before galvanizing for superior corrosion resistance. An adjustable cast-iron feeder reduces feed waste, and the anti-crush rail plus heat-lamp bracket create a safe, warm nursing environment. Easy to clean and disinfect, it is an ideal choice for improving piglet survival and management efficiency.

The nursery pen is designed for the weaning transition, addressing piglets' weak thermoregulation and stress sensitivity. The frame uses high-quality galvanized steel pipe for strength and anti-corrosion. The cast-iron slatted floor has precisely calculated gaps that let manure drop through without trapping hooves. A dedicated heat-lamp bracket allows flexible height adjustment to maintain an optimal micro-climate. The trough is formed from galvanized sheet with an anti-spill design, and its height can be adjusted as piglets grow. Panels connect via pins for fast assembly and flexible grouping, providing a safe bridge to the finishing stage.

The fattening pen is designed for pigs from 30 kg to market weight and is the most widely used pen type. The frame uses thickened galvanized steel pipe to withstand repeated impacts from adult pigs. Compared with nursery pens, each unit offers more space to reduce stress and support weight gain. The heavy-duty cast-iron slatted floor handles higher loads and drains urine and feces quickly. A large automatic feeder cuts refilling frequency, and modular panels can be combined into groups of any size. The mature surface treatment keeps the pen durable in humid, high-temperature barns.

The slatted floor is a core component of pig barn flooring, directly affecting hygiene and herd health. Made from high-strength HT200 gray cast iron with strict heat treatment, it offers excellent compressive and wear resistance. The gap spacing is graded for different pig sizes, allowing manure and urine to pass without hindering movement. The anti-slip surface increases friction to prevent falls. Cast iron resists corrosion and aging in humid, ammonia-rich barns, lasting over 10 years. A lower-cost concrete version suits budget-conscious farms. Both types have smooth surfaces for easy high-pressure washing.

The pig pen gate is a key partition component for grouping and transferring pigs. The frame is made from thickened galvanized steel pipe, resisting deformation and staying aligned over time. The gate leaf consists of welded horizontal and vertical pipes, with gaps balanced for ventilation, light, and pig containment. Stainless-steel hinges open smoothly and resist rust. A stainless latch closes securely to prevent pigs from pushing it open. Surface treatment uses hot-dip galvanizing or powder coating to block moisture and ammonia. Multiple styles include single-door, double-door, and flap gates; some models can add observation windows or feed slots.

The feed silo is the core storage device of an automatic feeding system. The body is roll-formed from high-quality galvanized steel sheet with uniform welds and good sealing to prevent moisture clumping and mold. The standard 10-ton capacity covers 3–5 days of feed for a medium-sized herd, reducing refill labor. The cone bottom has a precisely calculated slope for smooth gravity flow with no dead corners, eliminating bridging. A multifunction rain cap keeps out water and debris, and a level-gauge port supports automated inventory monitoring. The inlet has a sealed lid for dust and rodent protection. Ladders and platforms simplify maintenance, while a thickened flange base keeps the silo stable when full.

The automatic feed line connects the silo to troughs and is the key to automated feeding. It consists of a drive motor, reducer, traction cable, traveling hopper, corner units, and a control system. The motor power is adjustable from 0.75 to 1.5 kW, with a reducer for smooth low-speed operation below 65 dB. The cable runs inside a galvanized protective pipe along the barn, and the traveling hopper delivers feed precisely to each trough. Corner units use precision gears for smooth directional changes. A PLC controller enables timed, rationed feeding. The compact system adapts to any barn layout, cutting labor and boosting efficiency.

The feed trough is the terminal dispensing device of the feeding system, directly affecting feed utilization and the eating experience. The body is precisely stamped from 1.5 mm galvanized sheet with a smooth, burr-free surface that resists buildup and is easy to clean. An arc-shaped guide at the bottom works with an adjustable baffle to control flow rate and pile height, preventing spillage. The square-tube support frame is stable, with anti-slip rubber pads at the base. Used with the traveling hopper, the line opens each trough gate in sequence for precise rationed feeding. Models are available for nursery, finishing, and sow stages.

The manure scraper is the core equipment for mechanized manure removal in flat-floor barns. It consists of a drive system, traction chain, scraper blades, track, and tensioner. The enclosed gear motor outputs 1.1–2.2 kW with high torque and IP65 protection for reliable operation in humid, corrosive conditions. The chain is high-strength galvanized alloy steel, heat-treated for wear and fatigue resistance. Multiple U-shaped blades are spaced adjustable for thorough cleaning. The track is made from galvanized channel steel, and the tensioner keeps the chain taut. Overload and limit switches stop the machine automatically in abnormal conditions, protecting both equipment and workers.

The solid-liquid separator is key equipment for livestock waste treatment, separating pig manure slurry into solid and liquid phases for compliant disposal and resource reuse. It uses screw pressing: a tapered screw shaft rotates at low speed with high torque, squeezing the material so water filters through the screen while solids are pushed out. The 304 stainless screen is corrosion- and wear-resistant, with customizable mesh. A stirring device at the inlet prevents clogging. The 7.5–15 kW gear motor lets you match power to throughput. The PLC touchscreen monitors parameters in real time and adjusts feed and screw speed automatically, with complete alarm protection. The separated dry matter has moisture below 50%, ready for composting; the filtrate can go to further treatment or irrigation.

The nipple drinker is the terminal device of a pig farm water system, providing clean drinking water. The valve body is precision-cast from high-quality brass with smooth internal channels for corrosion resistance. The lever is food-grade ABS, smooth and comfortable for pigs to lick, with a sensitive spring return. A precision rubber seal ensures zero dripping when closed, saving water and keeping the pen dry. The outlet angle matches the natural drinking posture for a stable, gentle flow. Models are graded by stage: low-outlet for nursery pigs, standard for finishers, and high-flow for breeding stock. Threaded connection installs directly on the supply pipe; some premium models include a splash guard.

The water basin is a fixed drinking device for group use in nursery and finishing pens. The body is injection-molded from food-grade PP, non-toxic, odorless, corrosion- and aging-resistant, with a smooth surface that cleans easily. The generous capacity serves multiple pigs at once. A stainless float valve inside opens automatically when the level drops and closes when full, keeping the water at a constant height without manual work. The standard threaded inlet connects directly to the supply line, and some models include a pressure regulator. Anti-slip pads at the corners prevent movement. Compared with nipple drinkers, the basin delivers more water with a constant level, ideal for finishing pigs with higher water demand.

The drinking cup is a water-saving device that releases water on demand, avoiding evaporation and overflow from open basins. The body is precision-stamped from 304 stainless sheet with rounded, burr-free edges that resist corrosion and are easy to clean. Inside, a precision valve core opens when the pig presses the cup edge with its snout or lip, and a spring resets it when released, delivering water only as needed. The standard threaded bottom connects quickly to a supply hose or rigid pipe, and the mounting height adjusts to the pen. Compared with nipple drinkers, the cup offers more controlled flow and less splash, making it ideal for humidity-sensitive nursery stages. The stainless material keeps water hygienic and prevents bacterial growth.

The negative-pressure fan is the core ventilation device of a pig barn climate system. The housing is molded from FRP, resisting corrosion and aging in humid, ammonia-rich air without deforming or fading. The impeller is precision die-cast aluminum with strict dynamic balancing for low vibration and noise. The enclosed external-rotor YE2 three-phase motor delivers 0.75–1.5 kW with IP55 protection and Class F insulation for continuous operation in harsh conditions. Automatic louvers open when the fan starts and close when it stops, keeping out insects and odors. The outlet guide optimizes airflow for longer throw. Rated airflow reaches 25,000 m³/h, and paired with cooling pads it can lower indoor temperature by 5–10 °C, greatly reducing heat stress.

The cooling pad is the core component of a negative-pressure ventilation system, working with fans to control barn climate. The media is made from imported special cellulose fiber paper, processed for excellent water absorption and strength. Multi-pass resin treatment keeps the pad rigid when wet, with high tensile strength and a service life over 5 years. The 100 mm deep corrugation greatly increases the air-water contact area for better evaporative cooling. Aluminum alloy frames on both sides are light, strong, and corrosion-resistant. A top distribution pipe with a small pump creates an even water film. When outdoor air above 35 °C is drawn through the wet pad, evaporation absorbs heat and lowers the incoming air temperature by 5–12 °C while adding humidity, creating a cooler, more comfortable environment for pigs.
