Description

Technical Field

[0001] The invention relates to the technical field of degradation treatment, in particular to an automatic cattle dung degradation device used for cattle breeding. Background Art

[0002] In the process of cattle breeding, cow dung is usually treated by degradation, that is, the cow dung is mixed with soil, and then a group of earthworms are added to the mixed cow dung soil, relying on the earthworms to biodegrade the cow dung soil to meet environmental protection requirements.

[0003] Since cow dung contains manure water, after mixing with soil, the manure water content of cow dung soil is relatively high, which affects the growth and reproduction of earthworms in the cow dung soil. Therefore, before degradation, the cow dung soil needs to be dehydrated to a certain extent, but the existing degradation treatment equipment cannot achieve this function. Summary of the invention

[0004] The object of the present invention is to provide an automatic cow dung degradation device for cattle breeding to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An automatic cattle dung degradation device for cattle breeding, comprising:

[0007] A degradation treatment chamber with an open top, a connecting cavity is provided at the lower end of the degradation treatment chamber, a plurality of filter holes are provided at the inner bottom wall of the degradation treatment chamber, and the filter holes are connected to the connecting cavity;

[0008] A lifting mechanism is installed on the degradation processing bin, and a squeezing plate is drivingly connected to the lifting mechanism. The squeezing plate is driven by the lifting mechanism to penetrate into the degradation processing bin, and at least one earthworm delivery mechanism is arranged on the squeezing plate.

[0009] Furthermore, a discharge port is provided on the lower outer wall of the degradation treatment bin, and the discharge port is communicated with the interior of the degradation treatment bin. The degradation treatment bin is also provided with a drainage port communicated with the communication cavity.

[0010] Furthermore, the lifting mechanism comprises a column vertically fixed on the degradation treatment chamber, the upper end of the column is fixed with a top plate, a hydraulic cylinder is vertically installed on the top plate, and a piston rod of the hydraulic cylinder is connected to the extrusion plate.

[0011] Furthermore, an annular mounting groove is provided on the periphery of the extrusion plate, and a sealing bag is sleeved on the annular mounting groove.

[0012] Furthermore, air is stored inside the sealing bag, and an inflation interface is installed on the sealing bag, and the inflation interface passes through the extrusion plate.

[0013] Furthermore, the earthworm delivery mechanism comprises:

[0014] A storage bin vertically arranged on the extrusion plate, wherein the interior of the storage bin is hollow and a notch-shaped delivery port is provided on its periphery;

[0015] A rotating cover coaxially mounted in the storage bin, wherein after the rotating cover rotates around the axial direction of the storage bin to a fixed angle, the rotating cover closes the delivery port;

[0016] A rotation driving unit is arranged on the extrusion plate, and the rotation driving unit is used to drive the rotating cover to rotate when the extrusion plate moves downward, thereby opening the mouth of the delivery port.

[0017] Furthermore, a cone head is coaxially fixed to the lower end of the storage bin.

[0018] Furthermore, the rotation drive unit comprises:

[0019] A flange sleeve vertically embedded on the extrusion plate, the flange sleeve slidably sleeved on the storage bin, and the flange sleeve is key-connected with the storage bin;

[0020] A fixing frame connected to the extrusion plate, wherein the fixing frame is located above the extrusion plate;

[0021] A rotating shaft coaxially fixed to the upper end of the rotating cover, the rotating shaft passing through the storage bin and rotating freely;

[0022] A bushing is embedded in the fixing frame, and the bushing is slidably mounted on the upper end of the rotating shaft. Two balls are rotatably embedded in the inner hole wall of the bushing. A rolling groove for the balls to engage is opened on the periphery of the rotating shaft. The rolling groove includes a spiral groove and a straight groove from top to bottom, and the balls roll freely in the spiral groove and the straight groove.

[0023] Furthermore, the upper end of the rotating shaft passes through the bushing and is sleeved with a nut.

[0024] Furthermore, a spring is sleeved on the rotating shaft, and two ends of the spring in the direction of elastic force elastically press against the fixing frame and the storage bin respectively.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention drives the squeezing plate to move downward through a lifting mechanism, so that the squeezing plate squeezes the cow dung and soil mixture in the degradation treatment bin. During the squeezing process, fecal water can be quickly filtered out from the filter holes, thereby reducing the fecal water content in the cow dung and soil mixture, so that the growth and reproduction of earthworms in the cow dung and soil mixture are less affected. In addition, after the squeezing plate moves downward to a certain position in the degradation treatment bin, the earthworm delivery mechanism can deliver the earthworms into the dehydrated cow dung and soil mixture, thereby facilitating the degradation treatment operation.

[0027] The present invention provides a sealing bag, and the sealing bag contacts the inner wall of the degradation treatment bin, so that when the extrusion plate slides in the degradation treatment bin, the gap between the extrusion plate and the inner wall of the degradation treatment bin can be reduced. In addition, by providing an inflation interface, when the extrusion plate moves upward in the degradation treatment bin, the sealing bag is deflated, so that there is a certain gap between the extrusion plate and the inner wall of the degradation treatment bin, so that when the extrusion plate moves upward, the fecal water in the communication cavity will not flow back into the cow dung in the degradation treatment bin.

[0028] According to the present invention, after the extrusion plate moves downward to a certain position, the bottom of the storage bin is blocked by the bottom wall of the degradation treatment bin, so that when the extrusion plate continues to move downward, the storage bin will move relative to the extrusion plate, so that the rotating shaft and the bushing will slide relative to each other, and the balls on the bushing will roll in the rolling grooves on the rotating shaft. During the rolling process, the rotating shaft will rotate, so that the rotating cover will rotate, and then the mouth of the delivery port will be opened, so that the earthworms in the storage bin can escape from the delivery port and enter the cow dung, thereby completing the automatic delivery of the earthworms.

[0041] See also Figure 1 - Fig. 9 The present invention provides a technical solution: an automatic degradation device for cattle dung used in cattle breeding, comprising a degradation processing bin 2 with an open top, a connecting cavity 15 is provided at the lower end of the degradation processing bin 2, a plurality of filter holes 14 are provided on the inner bottom wall of the degradation processing bin 2, the filter holes 14 are connected with the connecting cavity 15, a discharge port 13 is provided on the lower outer wall of the degradation processing bin 2, the discharge port 13 is connected with the inside of the degradation processing bin 2, a drainage port 1 is also provided on the degradation processing bin 2 and is connected with the connecting cavity 15, and the upper end of the degradation processing bin 2 is provided with a corresponding Ear blocks are welded to the outer walls on both sides, and a column 12 is vertically welded on each ear block. A top plate 7 is welded to the upper ends of the two columns 12. A hydraulic cylinder 8 is vertically installed in the middle of the top plate 7. The piston rod of the hydraulic cylinder 8 penetrates the top plate 7 and slides freely. In addition, a connecting column is coaxially welded to the lower end of the piston rod of the hydraulic cylinder 8. An extrusion plate 6 is vertically welded to the lower end of the connecting column. The outer diameter of the extrusion plate 6 is slightly smaller than the inner diameter of the degradation treatment chamber 2. In addition, an annular mounting groove 24 (such as Figure 6As shown in the figure, a sealing bag 5 is coaxially mounted in the annular mounting groove 24, the sealing bag 5 is hollow inside, an inflation interface 10 is fixedly connected to the sealing bag 5, the inflation interface 10 passes through the extrusion plate 6, and the inflation interface 10 is connected to an external air pump through a pipeline, so that when the air pump is started, compressed air can be delivered to the inflation interface 10, so that the sealing bag 5 is in an expanded state, so that when the extrusion plate 6 slides in the degradation treatment bin 2, the gap between the extrusion plate 6 and the inner wall of the degradation treatment bin 2 can be supplemented by the sealing bag 5, that is, when the extrusion plate 6 slides downward in the degradation treatment bin 2, the sealing effect between the extrusion plate 6 and the inner wall of the degradation treatment bin 2 is better;

[0042] When the cow dung is degraded, the staff first puts (or transports) the cow dung and soil containing dung water into the degradation treatment bin 2, and then starts the hydraulic cylinder 8, the piston rod of the hydraulic cylinder 8 is extended, and then the extrusion plate 6 is driven to move downward. When the extrusion plate 6 moves downward into the degradation treatment bin 2, the air pump is started at the same time, and the compressed air is transported to the inflation interface 10, so that the sealing bag 5 is in an expanded state, so that the gap between the periphery of the extrusion plate 6 and the inner side wall of the degradation treatment bin 2 is filled, so that when the extrusion plate 6 moves downward in the degradation treatment bin 2, the cow dung in the degradation treatment bin 2 is squeezed, and the dung water in the cow dung is squeezed, and then flows from the filter hole 14 into the connecting cavity 15 for storage. When the storage reaches a certain level, the drain port 1 is connected through the external water pump, and then the dung water in the connecting cavity 15 is pumped out. After the extrusion plate 6 squeezes the dung water in the degradation treatment bin 2, the water content in the cow dung is reduced, and a certain amount of dung water is retained;

[0043] A plurality of flange sleeves 17 are vertically embedded on the extrusion plate 6, and a cylindrical storage bin 4 is coaxially penetrated on the flange sleeve 17. A cone head 3 is coaxially welded on the lower end of the storage bin 4. The cone head 3 is conducive to the storage bin 4 being inserted into the cow dung when the extrusion plate 6 moves downward. In addition, the storage bin 4 can slide freely up and down in the flange sleeve 17. The storage bin 4 is hollow inside and a delivery port 21 in the form of a notch is opened on its periphery. A rotating shaft 16 is coaxially penetrated on the storage bin 4. In addition, the rotating shaft 16 is rotatably connected to the storage bin 4. A rotating cover 11 is coaxially mounted in the storage bin 4. After the rotating cover 11 rotates around the axial direction of the storage bin 4 to a fixed angle, the rotating cover 11 closes the delivery port 21. In addition, the flange sleeve 17 and the storage bin 4 Key connection, a fixing frame 9 is installed on the connecting column on the extrusion plate 6, and the fixing frame 9 is located above the extrusion plate 6. The upper end of the rotating shaft 16 passes through the storage bin 4, and a bushing 22 is embedded on the fixing frame 9. The bushing 22 is slidably mounted on the upper end of the rotating shaft 16. Two balls 25 are rotatably embedded in the inner hole wall of the bushing 22. A rolling groove for the balls 25 to engage is opened on the periphery of the rotating shaft 16. The rolling groove includes a spiral groove 20 and a straight groove 23 from top to bottom. The balls 25 roll freely in the spiral groove 20 and the straight groove 23. The upper end of the rotating shaft 16 passes through the bushing 22 and is sleeved with a nut 19. A spring 18 is sleeved on the rotating shaft 16, and the two ends of the spring 18 in the elastic force direction elastically press against the fixing frame 9 and the storage bin 4 respectively;

[0044] When the extrusion plate 6 moves downward, it is subjected to the elastic resistance force of the spring 18, and the storage bin 4 will be inserted into the cow dung until the cone head 3 at the lower end of the storage bin 4 contacts the inner bottom wall of the degradation treatment bin 2. At this time, the extrusion plate 6 continues to move downward, and the storage bin 4 cannot continue to move downward. As the extrusion plate 6 moves downward, the bushing 22 moves relative to the rotating shaft 16, so that the ball 25 rolls from the straight groove 23 to the spiral groove 20. The inner wall of the spiral groove 20 generates an extrusion force on the ball 25, so that the rotating shaft 16 rotates 90 degrees, so that the rotating cover 11 rotates around the axial direction of the storage bin 4, so that the delivery port 21 is in an open state. At this time, the earthworms in the storage bin 4 can escape and drill into the cow dung. It should be noted that the cow dung at this time is not in a compact state, but is still fluffy, so that the earthworms can drill into the cow dung. In addition, the spring 18 is in a compressed state and accumulates elastic potential energy.

[0045] The working principle of the present invention is as follows: when degrading cow dung, the staff first puts (or transports) the cow dung containing fecal water and soil into the degradation treatment chamber 2, and then starts the hydraulic cylinder 8, the piston rod of the hydraulic cylinder 8 extends, and then drives the extrusion plate 6 to move downward. When the extrusion plate 6 moves downward into the degradation treatment chamber 2, the air pump is started at the same time, and then the compressed air is transported to the inflation interface 10, so that the sealing bag 5 is inflated, so that the gap between the periphery of the extrusion plate 6 and the inner wall of the degradation treatment chamber 2 is filled. When the squeezing plate 6 moves downward in the degradation treatment bin 2, it will squeeze the cow dung in the degradation treatment bin 2. During squeezing, the manure water in the cow dung is squeezed, and then flows from the filter hole 14 into the connecting cavity 15 for storage. When the storage reaches a certain level, the drain port 1 is connected through an external water pump to further extract the manure water in the connecting cavity 15. After the squeezing plate 6 squeezes the manure water in the degradation treatment bin 2, the water content in the cow dung is reduced, and a certain amount of manure water is retained. At this time, the cow dung is not in a compact state, but still in a fluffy state.

[0046] When the extrusion plate 6 moves downward, it is subjected to the elastic resistance force of the spring 18, and the storage bin 4 will be inserted into the cow dung until the cone head 3 at the lower end of the storage bin 4 contacts the inner bottom wall of the degradation treatment bin 2. At this time, the extrusion plate 6 continues to move downward, and the storage bin 4 cannot continue to move downward. As the extrusion plate 6 moves downward, the bushing 22 moves relative to the rotating shaft 16, so that the ball 25 rolls from the straight groove 23 to the spiral groove 20. The inner wall of the spiral groove 20 generates an extrusion force on the ball 25, so that the rotating shaft 16 rotates 90 degrees, so that the rotating cover 11 rotates around the axial direction of the storage bin 4, so that the delivery port 21 is in an open state. At this time, the earthworms in the storage bin 4 can escape and drill into the cow dung.
