Description

Technical Field

[0001] This utility model belongs to the technical field of manure cleaning equipment, specifically a manure cleaning device for pig farms. Background Technology

[0002] As the pig farming industry develops towards large-scale and intensive operations, the amount of manure produced in pigsties has increased significantly. Timely and efficient manure removal has become a crucial link in ensuring the health of pig herds, improving the breeding environment, and reducing the risk of disease. Currently, manure removal in pigsties mainly relies on manual sweeping or simple mechanical assistance. Manual sweeping requires frequent entry into the pens, which is not only labor-intensive and inefficient, but also prone to manure accumulation due to untimely cleaning, leading to the growth of pathogenic bacteria such as E. coli and Salmonella, while also producing harmful gases such as ammonia and hydrogen sulfide, affecting the growth performance of pig herds. Simple mechanical cleaning often uses fixed scrapers to collect manure, but lacks a buffer structure. The scraper makes hard contact with the pigsty floor, which can easily cause scraper wear or manure leakage due to uneven ground. Existing manure cleaning equipment relies on gravity for solid-liquid separation, which is extremely inefficient. Processing large batches of manure is time-consuming and difficult to match the daily manure output of several tons in large-scale pig farms. This often leads to manure accumulation in the separation area, and the moisture content of the separated solid manure is insufficient to meet transportation and storage standards. This not only increases the weight and cost of transportation but also makes it prone to environmental pollution due to liquid leakage during transport. Therefore, new manure treatment equipment needs to be developed to meet these needs. Utility Model Content

[0003] To address the above technical problems, this utility model provides a manure cleaning device for pig farms.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a manure cleaning device for pigsties, comprising a cleaning component, a separation component, and a buffer component; the cleaning component includes a box body, a fixed box fixedly connected to the front end of the box body, a spiral collecting rod rotatably connected laterally inside the fixed box, and a conveying cylinder fixedly connected to the front position inside the box body, the first end of the conveying cylinder communicating with the fixed box; the separation component includes a liquid tank and a solid tank, the liquid tank fixedly connected to the middle of the box body, the solid tank fixedly connected to the rear of the box body, and a fixed plate fixedly connected to the top of the box body; the liquid... A filter screen is installed on the top of the box, and a separation plate is connected to the rear of the filter screen. The end of the separation plate is located at the upper part of the solid box. The discharge port of the conveying cylinder is located above the filter screen. The separation assembly also includes a third motor and a first pressure plate. The first pressure plate is slidably connected to the top of the box body. The third motor is fixedly connected to the upper rear side of the box body. The shaft of the third motor is keyed to a transmission screw. A connecting block is fixedly connected to the rear side of the first pressure plate. The connecting block is threadedly connected to the transmission screw. The buffer assembly includes a buffer spring disposed inside the fixed box. A buffer block is fixedly connected to the lower end of the buffer spring.

[0005] Furthermore, a support plate is fixedly connected to the end of the conveying cylinder, a first motor is fixedly connected to the support plate, and a spiral conveying rod is rotatably connected inside the conveying cylinder. The shaft of the first motor is fixedly connected to the spiral conveying rod.

[0006] Furthermore, the cleaning assembly also includes a collection box and a cleaning roller. The collection box is fixedly connected to the rear of the fixed box and communicates with the feed inlet of the conveying cylinder. The cleaning roller is rotatably connected to the front of the fixed box, and a scraper is fixedly connected to the front end of the buffer block.

[0007] Furthermore, a second motor is fixedly connected to the side of the fixed box, and the shaft of the second motor is fixedly connected to the spiral collecting rod. The spiral collecting rod is connected to the cleaning roller through a transmission belt.

[0008] Furthermore, the separation assembly also includes a reset spring and a second pressure plate, the second pressure plate being slidably connected inside the first pressure plate, the top of the first pressure plate being fixedly connected to the top of the reset spring, and the bottom of the reset spring being fixedly connected to the second pressure plate.

[0009] This utility model has the following advantages compared with the prior art:

[0010] 1. This utility model is equipped with a synchronously driven moving spiral collecting rod and a cleaning roller. After the cleaning roller stirs and loosens the feces, the spiral collecting rod gathers the feces towards the center through left and right reverse spiral blades. Combined with the spiral conveying rod driven by the first motor, the spiral lift conveys the feces in the conveying cylinder, forming a fully automated process and greatly reducing the intensity of manual labor.

[0011] 2. This utility model is equipped with a first pressure plate, which moves smoothly along the box body to ensure that the second pressure plate fits against the inner wall of the box body from left to right; at the same time, the return spring pushes the second pressure plate to fit tightly against the filter screen and the separation plate, forming a double seal in the horizontal and vertical directions to prevent side leakage of feces. After compression, the moisture content of the solid feces meets the requirements for subsequent transportation and storage, and the liquid flows accurately into the liquid tank through the filter screen, realizing complete separation of solid and liquid.

[0012] 3. This utility model is equipped with a buffer component. The buffer spring at the upper end of the buffer block can compensate for the unevenness of the pigsty floor in real time through elastic expansion and contraction, so that the scraper fixed at the front end of the buffer block is always in close contact with the ground, reducing the leakage rate of manure, while avoiding hard contact between the scraper and the ground, extending its service life and reducing the cost of parts replacement.

[0020] like Figures 1-5 The illustrated manure cleaning device for pig farms includes a cleaning component 1, a separation component 2, and a buffer component 3. The cleaning component 1 includes a housing 101, with a fixed box 107 fixedly connected to the front end of the housing 101. A spiral collecting rod 108 is laterally rotatably connected inside the fixed box 107. A conveying cylinder 104 is fixedly connected to the front position inside the housing 101, with its head end communicating with the fixed box 107. The separation component 2 includes a liquid tank 210 and a solid tank 211. The liquid tank 210 is fixedly connected to the middle of the housing 101, and the solid tank 211 is fixedly connected to the rear of the housing 101. A fixed plate 201 is fixedly connected to the top of the housing 101, and a filter screen 208 is installed on the top of the liquid tank 210. A separation plate 209 is connected to the filter screen 208. The end of the separation plate 209 is located at the top of the solid box 211. The discharge port of the conveying cylinder 104 is located above the filter screen 208. The separation assembly 2 also includes a third motor 202 and a first pressure plate 205. The first pressure plate 205 is slidably connected to the top of the box 101. The third motor 202 is fixedly connected to the upper rear side of the box 101. The shaft of the third motor 202 is keyed to a transmission screw 203. A connecting block 204 is fixedly connected to the rear side of the first pressure plate 205. The connecting block 204 is threadedly connected to the transmission screw 203. The buffer assembly 3 includes a buffer spring 302 disposed inside the fixed box 107. A buffer block 301 is fixedly connected to the lower end of the buffer spring 302.

[0021] The bottom of the housing 101 is fixedly connected with casters, and the top of the housing 101 has a groove.

[0022] To facilitate support of the first motor 102, a support plate 103 is fixedly connected to the end of the conveying cylinder 104, and the first motor 102 is fixedly connected to the support plate 103. A spiral conveying rod 105 is rotatably connected inside the conveying cylinder 104, and the shaft of the first motor 102 is fixedly connected to the spiral conveying rod 105.

[0023] To facilitate the crushing of feces, the cleaning assembly 1 also includes a collection box 106 and a cleaning roller 109. The collection box 106 is fixedly connected to the rear of the fixed box 107 and communicates with the feed inlet of the conveying cylinder 104. The cleaning roller 109 is rotatably connected to the front of the fixed box 107, and a scraper 110 is fixedly connected to the front end of the buffer block 301.

[0024] To facilitate synchronous rotation, a second motor 11 is fixedly connected to the side of the fixed box 107. The shaft of the second motor 11 is fixedly connected to the spiral collecting rod 108. The spiral collecting rod 108 is connected to the cleaning roller 109 through the transmission belt 112.

[0025] To facilitate the squeezing of fecal water, the separation assembly 2 also includes a return spring 207 and a second pressure plate 206. The second pressure plate 206 is slidably connected inside the first pressure plate 205. The top of the first pressure plate 205 is fixedly connected to the top of the return spring 207, and the bottom of the return spring 207 is fixedly connected to the second pressure plate 206.

[0026] The specific working process of this utility model is as follows:

[0027] In use, the second motor 111 is started, and the power output end of the second motor 111 drives the spiral collecting rod 108 to rotate. At the same time, the spiral collecting rod 108 drives the cleaning roller 109 to rotate synchronously through the transmission belt 112. At this time, the scraper 110 fixed at the front end of the buffer block 301 moves with the whole device to scrape off the manure on the pigsty floor. The buffer spring 302 installed at the upper end of the buffer block 301 compensates for the unevenness of the ground in real time through elastic expansion and contraction, ensuring that the scraper 110 always fits tightly with the ground and avoids hard contact damage with hard protrusions. After the scraped manure is stirred and loosened by the brush bristles on the surface of the cleaning roller 109, it is assisted in being transported to the spiral collecting rod 108. Because the spiral blades on the left and right sides of the spiral collecting rod 108 rotate in opposite directions, the rotation generates a converging thrust towards the middle, which gathers the manure on both sides towards the middle and finally falls into the collection box 106 for storage through the discharge port at the bottom of the fixed box 107. Next, the first motor 102 is started, and its power output end drives the spiral conveyor rod 105 to rotate inside the conveyor cylinder 104. The spiral lift of the spiral blades conveys the feces in the collection box 106 upward and falls onto the filter screen 208 through the discharge port at the top of the conveyor cylinder 104.

[0028] The cleaning component 1 enables automated and efficient collection of feces. A second motor 111 synchronously drives a spiral collecting rod 108 and a cleaning roller 109. After the cleaning roller 109 loosens the feces, the spiral collecting rod 108 uses left and right counter-spiral blades to gather the feces towards the center. Combined with the spiral conveying rod 105 driven by the first motor 102, the feces are conveyed by the spiral lifting force within the conveying cylinder 104, forming a fully automated process that significantly reduces manual labor intensity. This invention uses a buffer component 3 to ensure thorough cleaning and component durability. The buffer spring 302 at the upper end of the buffer block 301 can elastically compensate for unevenness in the pigsty floor in real time, ensuring that the scraper 110 fixed to the front end of the buffer block 301 always fits tightly against the ground, thereby reducing feces leakage and preventing hard contact with the ground, extending its service life and reducing replacement costs.

[0029] During extrusion, the third motor 202 is activated. The power output of the third motor 202 drives the keyed transmission screw 203 to rotate, which in turn drives the connecting block 204 to move forward along the screw axis, thereby causing the first pressure plate 205 welded to the front end to move forward synchronously. The two ends of the first pressure plate 205 are slidably connected to the corresponding grooves opened on the inner wall of the housing 101. The grooves form a rigid constraint on the movement trajectory of the first pressure plate 205. At the same time, the inner wall of the first pressure plate 205 is slidably connected to the T-shaped slider of the second pressure plate 206 through a T-shaped groove, which restricts the rotation of the second pressure plate 206 and ensures that it moves synchronously with the first pressure plate 205. This ensures that the left and right ends of the second pressure plate 206 always adhere to the inner wall of the housing 101, blocking the fecal leakage channel laterally. As the first pressure plate 205 continues to move forward, the inclined surface of the filter screen 208 generates an upward supporting reaction force along the inclined surface on the lower end of the second pressure plate 206. Meanwhile, the first pressure plate 205 maintains a constant forward driving force under the drive of the transmission screw 203. The two form an axial relative movement tendency, causing the second pressure plate 206 to gradually retract into its interior along the T-shaped groove of the first pressure plate 205. At the same time, the pre-installed return spring 207 between the first pressure plate 205 and the second pressure plate 206 is compressed, generating an elastic push. The force applied to the second pressure plate 206 ensures that its lower end is tightly fitted to the surface of the filter screen 208 and the separation plate 209, preventing feces from leaking out from the gap between the pressure plate and the filter screen 208. The filter screen 208 is slidably connected to the corresponding grooves on the fixing plate 201 and the separation plate 209 via limiting blocks at both ends. This facilitates subsequent removal and cleaning while preventing displacement of the filter screen 208 during the compression process. As the first pressure plate 205 and the second pressure plate 206 move forward, they continuously compress the feces. The liquid generated by this compression passes through the mesh of the filter screen 208 under gravity and flows into the liquid tank 210 below. After collection and dehydration, the third motor 202 is reversed, and the transmission screw 203 drives the connecting block 204, the first pressure plate 205 and the second pressure plate 206 to move backward synchronously. The supporting reaction force of the filter screen 208 on the second pressure plate 206 gradually disappears, the reset spring 207 releases the compression force, and pushes the second pressure plate 206 to slide out of the first pressure plate 205 along the slide groove to reset until the second pressure plate 206 is completely separated from the separation plate 209. At this time, the dehydrated solid feces slide down the inclined separation plate 209 into the solid box 211 for collection under the action of gravity, completing the entire process of clean collection and solid-liquid separation of feces.
