The device enables the dung to be spread over a large area to a thinner thickness first, so that the liquid in the dung can fully flow out before squeezing. The large area is spread to a thinner thickness, which requires a large-area squeezing plate when squeezing again. The increased volume of the squeezing plate will make the equipment bulky. For this reason, a push plate, a side push plate and a gathering plate are used to gather from three directions, so that the dung can be quickly gathered to a certain thickness, which not only meets the need to fully discharge the liquid in advance, but also meets the need to gather the dung to a certain thickness for squeezing.

[0017] The pushing plate can push the manure toward the lifting baffle during its movement, and the pushing plate pushes the side push plate to move, so that the active block and the driven plate can be squeezed and matched to drive the collecting plates on both sides to move relative to each other, thereby realizing the function of collecting cow dung from three directions; During the movement of the extrusion plate, the function of driving the sliding seat to move is realized through the extrusion cooperation of the roller and the guide plate, so that the scraper plate can move to the top of the cow dung. When the extrusion plate is reset, the roller will be separated from the guide plate, so that the sliding seat can be reset under the push of the fourth spring, and drive the scraper plate to push the cow dung off the filter plate. In this way, the return action of the extrusion plate is used as a driving force for the scraper plate. When the extrusion plate is returned, the cow dung formed by the block can be discharged.

[0018] During the movement of the extrusion plate, the function of driving the push plate to move is realized through the transmission mechanism such as the active rack, the active gear and the transmission rod, and the transmission rod will drive the shaking top block and the wave plate to squeeze and cooperate, so that the filter plate shakes to increase the outflow rate of the liquid in the feces; The front and rear stop rods block the movement of the position control rod, so that the position control rack and the position control gear can drive the scraper plate to switch states during the movement, so that the scraper plate can move above the cow dung or scrape off the cow dung. The front and rear buckles are elastic buckles, which can not only fix the position control rod, but also facilitate the position control rod to be inserted or disengaged.

The two fixing rods 104 are provided with the folding plates 105 in a relative manner, and the lower end of the folding plates 105 contacts the top of the filter plate 102. The guide rod of the folding plates 105 is provided with a first spring 106. When the two folding plates 105 move relative to each other, the first spring 106 will be compressed. The folding plates 105 are slidably connected with the side push plates 107. The sliding direction of the side push plates 107 on the folding plates 105 is the same as the moving direction of the push plates 103.

The push plate 103 pushes the feces and sewage on the filter plate 102, and the push plate 103 pushes the two side push plates 107 during the movement, so that the side push plates 107 also move in the direction of the lifting baffle 111. During the movement of the two side push plates 107, the active block 110 will squeeze the driven plate 109, so that the two side push plates 107 can drive the two gathering plates 105 to move relative to each other, so that the spread cow dung is gathered to a certain thickness through the push plate 103, the side push plate 107 and the gathering plate 105, so as to facilitate extrusion and dehydration. During the above movement, the side push plate 107 and the gathering plate 105 will compress the first spring 106 and the second spring 108, and the hydraulic cylinder 112 will drive the squeezing plate 113 to move downward, and the squeezing plate 113 will squeeze and dehydrate the gathered cow dung. Water treatment, thereby separating the solid cow dung and the liquid, after the extrusion is completed, the hydraulic cylinder 112 is controlled to contract, and the pushing plate 103 is reset in the direction away from the lifting baffle 111, and the first spring 106 and the second spring 108 will push the side push plate 107 and the folding plate 105 to gradually reset, and then the lifting baffle 111 is controlled to move downward, so as to push the cow dung after dehydration from the filter plate 102; this device allows the dung to be spread over a large area to a thinner thickness first, so that the liquid in the dung can fully flow out before squeezing, and then Then, the pushing plate 103, the side pushing plate 107 and the gathering plate 105 are used to gather the manure from three directions, so that the manure can be quickly gathered to a certain thickness, which not only meets the need to fully discharge the liquid in advance, but also meets the need to gather the manure to a certain thickness for easy extrusion, so that the extrusion plate 113 can extrude at a faster speed, improves the efficiency of extrusion dehydration, and helps to extend the service life of the device. In addition, the use of a filter press dehydration method can fully compress the cow dung, reduce the volume of the cow dung after dehydration, and facilitate transportation and storage.

[0031] like Figure 1 , Figure 2 and Figure 5As shown, it also includes a transmission mechanism for driving the push plate 103 to move, the transmission mechanism is connected to the extrusion plate 113, the transmission mechanism includes a transmission plate 2, a third spring 201, a transmission frame 202, a transmission rod 203, a transmission rack 204, a transmission gear 205, a first pulley 206, a drive frame 207, a second pulley 208, a transmission belt 209, a driving gear 210 and a driving rack 211, the push plate 103 is slidably connected with the transmission plate 2, the guide rod of the push plate 103 is sleeved with the third spring 201, when the transmission plate 2 approaches the push plate 103, the third spring 201 will be compressed, the separation frame 1 is fixedly connected with the transmission frame 202, the transmission frame 202 is slidably connected with the transmission rack 204 in the horizontal direction, and the transmission rack 204 and the transmission plate 2 are fixedly connected with Transmission rod 203, transmission frame 202 is coaxially rotatably connected with transmission gear 205 and No. 1 pulley 206, transmission frame 202 is fixedly connected with driving frame 207, hydraulic cylinder 112 is fixedly connected to driving frame 207, and sliding plates for guiding it are fixedly connected on both sides of lifting baffle plate 111, and one end of the sliding plate away from the lifting baffle plate 111 is slidably connected in the slideway opened on the inner side of driving frame 207 in the vertical direction, driving frame 207 is coaxially rotatably connected with driving gear 210 and two No. 2 pulleys 208, and transmission belt 209 is wound around No. 2 pulley 208 and No. 1 pulley 206 on the same side, and the diameter of No. 2 pulley 208 is larger than the diameter of No. 1 pulley 206, and driving rack 211 is fixedly connected to extrusion plate 113, and driving rack 211 is meshed with driving gear 210.

[0032] When the extrusion plate 113 moves, it will drive the active rack 211 to move synchronously. When the active rack 211 moves downward, it will drive the transmission rack 204 to slide in the direction of the lifting baffle 111 through the active gear 210, the second pulley 208, the transmission belt 209, the first pulley 206 and the transmission gear 205, so that the transmission rack 204 pushes the push plate 103 in the direction of the lifting baffle 111 through the transmission rod 203 and the transmission plate 2. When the ends of the push plate 103 and the gathering plate 105 are in contact, the push plate 103 cannot continue to move in the direction of the lifting baffle 111. At this time, the extrusion plate 113 needs to continue to move downward to squeeze the gathered feces and sewage. In this process, the third spring 201 will be compressed to provide a buffering effect; when the extrusion plate 113 moves upward, it will drive the push plate 103 to move and reset in the direction away from the lifting baffle 111 through the transmission mechanism.

[0033] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 6 and Figure 7As shown, it also includes a scraper mechanism for pushing the dehydrated cow dung from the filter plate 102. The scraper mechanism is connected to the extrusion plate 113. The scraper mechanism includes a sliding seat 3, a scraper bracket 302, a scraper plate 303 and an adjusting component. The lower end of the support rod 101 is slidably connected to the sliding seat 3 in the horizontal direction. The scraper bracket 302 is fixed to the sliding seat 3. The scraper bracket 302 is rotatably connected to the scraper plate 303. The scraper plate 303 is connected to the adjusting component. The adjusting component is used to rotate the scraper plate 303 so as to push the cow dung from the filter plate 102.

[0034] During the upward movement of the extrusion plate 113, the sliding seat 3 is controlled to slide in the direction of the lifting baffle 111, and the lifting baffle 111 is controlled to move downward to avoid affecting the scraping of cow dung. During this process, the scraper plate 303 is Figure 7 When the sliding seat 3 is about to complete the reset, the adjustment component will drive the scraper plate 303 to rotate and reset to a horizontal state, so as to push the cow dung on the filter plate 102.

[0035] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the adjustment component includes a position control rack 4, a position control gear 401, a position control rod 402, a front buckle 403, a rear buckle 404, a rear stop rod 405 and a front stop rod 406. The scraper bracket 302 is slidably connected with the position control rack 4 in the horizontal direction. The position control gear 401 is fixedly connected to the rotating shaft of the scraper plate 303. The position control gear 401 and the position control rack 4 are meshed.

The front buckle 403 and the rear buckle are fixedly connected to the scraper bracket 302. 404, C-shaped slots are provided on the front buckle 403 and the rear buckle 404, the front buckle 403 and the rear buckle 404 are relatively arranged, the front buckle 403 and the rear buckle 404 are used to fix the control rod 402 to prevent the scraper plate 303 from rotating at will, and two rear stop rods 405 are symmetrically fixed on the separation frame 1, the rear stop rod 405 is used to push the control rod 402 to the front buckle 403, and the front stop rod 406 is fixed on the fixing rod 104, and the front stop rod 406 is used to push the control rod 402 toward the rear buckle 404.

[0036] When the scraper plate 303 is about to move above the other end of the cow dung, the front stopper 406 will prevent the control rod 402 from continuing to move. Therefore, when the sliding seat 3 drives the scraper plate 303 to continue to move, the control rod 402 and the control rack 4 will remain stationary, and the control rod 402 will disengage from the front buckle 403 and move into the rear buckle 404. The control rack 4 will drive the scraper plate 303 to rotate ninety degrees counterclockwise through the control gear 401, thereby rotating the scraper plate 303 to a vertical state so as to facilitate the scraping of cow dung from the filter plate 102 during the resetting process. When the reset is about to be completed, the position control rod 402 will contact the rear stopper 405, so the position control rod 402 will be separated from the rear buckle 404 and move into the front buckle 403 during the reset process of the sliding seat 3, so that the position control rack 4 drives the scraper 303 to rotate clockwise and reset to a horizontal state through the position control gear 401; the front stopper 406 and the rear stopper 405 block the movement of the position control rod 402, so that the position control rack 4 and the position control gear 401 can drive the scraper 303 to switch states during the movement, so that the scraper 303 can move to the top of the cow dung or scrape the cow dung.

[0037] like Figure 7 and Figure 8 As shown, the front buckle 403 and the rear buckle 404 are both elastic buckles, and the control rod 402 will be engaged with or disengaged from the front buckle 403 and the rear buckle 404 only when a large force is applied to it.

[0038] By setting the front buckle 403 and the rear buckle 404 as elastic buckles, the position control rod 402 can be automatically engaged or disengaged during the movement of the sliding seat 3, and the position control rod 402 will not slide easily to ensure that the scraper plate 303 can clean cow dung normally.

The adjusting guide rod 6 is sleeved with a sixth spring 601, and the connecting rod 305 is slidably connected to the adjusting guide rod 6. When the connecting rod 305 slides in the direction close to the driven bracket 307, the sixth spring 601 is compressed.

During the upward movement of the extrusion plate 113, the connecting rod 305 squeezes the guide plate 304 through the roller 306, so that the sliding seat 3 moves in the direction close to the pushing plate 103.

[0040] During the movement of the extrusion plate 113, the driven bracket 307 will be driven to move synchronously. During the downward movement of the driven bracket 307, the roller 306 will contact the inclined surface on the upper side of the guide plate 304. The guide plate 304 will squeeze the connecting rod 305 in the direction of the driven bracket 307 through the roller 306, and will compress the sixth spring 601. When the roller 306 moves to the bottom of the guide plate 304, the sixth spring 601 will push the connecting rod 305 to reset, so that the roller 306 moves to the lower side of the guide plate 304. During the upward movement of the driven bracket 307, the roller 306 will squeeze the inclined surface on the inner side of the guide plate 304, so that the guide plate 304 drives the scraper bracket 302 and the sliding seat 3 to close The fourth spring 301 is compressed when the extrusion plate 113 drives the driven bracket 307 to reset upward, and the roller 306 and the guide plate 304 are disengaged, so that the fourth spring 301 can push the sliding seat 3 to reset.
