Technical Field

[0001] The utility model relates to the field of breeding, in particular to a device for treating and recycling pig manure in pig breeding. Background Technique

[0002] In the process of pig breeding, a large amount of manure is often generated. This manure can be used as raw material for farmyard manure or biogas digesters for re - utilization. However, the water content in pig manure is too high, which leads to inconvenient transportation and is not conducive to storage. Therefore, dehydration treatment of the manure is required.

[0003] In the prior art, the utility model patent with the application number CN202021919574.6 discloses a manure treatment device for pig breeding, including a discharge pipe. A spiral extrusion pipe is installed at the front end of the discharge pipe, a feeding hopper is installed at the top of the discharge pipe, a sealing cover is provided at the output end of the spiral extrusion pipe, and a discharge pipe communicating with the spiral extrusion pipe is installed at the end of the sealing cover. A discharge port plug is installed on the inner side of the mounting plate through a spring. The output end of the motor is connected to a speed reducer, and a spiral extrusion rod is installed at the output end of the speed reducer. A squeezing filter plate is provided at the bottom inside the spiral extrusion pipe. The output shaft of the speed reducer can drive the spiral extrusion rod to extrude the manure, and cooperate with the squeezing filter plate to fully extrude and dehydrate the manure, so as to achieve the effect of solid - liquid separation.

[0004] However, when using the above - mentioned manure treatment device for pig breeding to extrude and dehydrate pig manure, a large amount of manure is likely to adhere to the inner wall of the discharge pipe and is not easy to discharge, increasing the cleaning difficulty inside the equipment, which needs to be improved. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for treating and recycling pig manure in pig breeding, so that the pig manure can be discharged more cleanly, in order to solve the defects proposed in the above - mentioned background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Pig manure treatment and recycling device for pig farming, including a frame. A hollow extrusion housing is fixedly installed on the frame. The extrusion housing is in the shape of a horizontally extending cylinder. The top of the extrusion housing is provided with a feeding port. One end of the bottom of the extrusion housing is provided with a discharging port. A plurality of water permeable holes are evenly distributed on the bottom wall at the other end of the extrusion housing. A guide sleeve is fixedly installed at one end of the extrusion housing. A movable column coaxially arranged with the extrusion housing is movably installed in the guide sleeve. One end of the movable column is fixedly installed with an extrusion plate located inside the extrusion housing. The extrusion plate is circular and matches the inner diameter of the extrusion housing. A shovel plate is fixedly installed on the side of the extrusion plate close to the water permeable holes. The shovel plate is in the shape of an arc that fits the inner wall of the extrusion housing. A driving mechanism is provided on the frame for driving the movable column to move and rotate along the guide sleeve.

[0008] As a preferred technical solution, the driving mechanism includes a mounting plate driven by a power device to move axially along the extrusion housing. The movable column is rotatably installed on the mounting plate. A motor for driving the movable column to rotate around its own axis is installed on the mounting plate.

[0009] As a preferred technical solution, a plurality of water passing holes are evenly distributed on the shovel plate.

[0010] As a preferred technical solution, elastic bending scraping parts are respectively provided at both circumferential ends of the shovel plate. The end of the scraping part away from the shovel plate bends towards the side close to the inner wall of the extrusion housing.

[0011] As a preferred technical solution, a funnel-shaped collecting trough is fixedly installed at the bottom of the extrusion housing. The upper end of the collecting trough covers the plurality of water permeable holes.

[0012] As a preferred technical solution, a sealing ring is embedded on the outer peripheral surface of the extrusion plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. In this application, when the shovel plate is located at the bottom of the extrusion plate, when the extrusion plate moves to the left, it can drive the shovel plate to shovel up some manure in the extrusion housing. When the extrusion plate drives the shovel plate to move above the discharging port, the motor is then used to drive the shovel plate to rotate to the top of the extrusion plate.

Detailed implementation manners

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Such as Figures 1 to 6As shown in the figure, the feces treatment and recycling device for pig breeding includes a frame 1. A hollow extrusion housing 2 is fixedly installed on the frame 1 by bolts. The extrusion housing 2 is in the shape of a horizontally extending cylinder. The extrusion housing 2 includes two semi-hulls arranged opposite to each other up and down. Both semi-hulls are in the shape of semi-cylinders, and the two semi-hulls are fixedly connected by bolts. An inlet 3 is provided at the middle position of the top of the extrusion housing 2, and a discharge port 4 is provided at the bottom of the right end of the extrusion housing 2 for discharging the dehydrated feces. The discharge port 4 deviates to the right below the inlet 3. A plurality of water permeable holes 5 are evenly distributed on the bottom wall of the left end of the extrusion housing 2 for discharging the water squeezed out by the feces. A guide sleeve 6 is fixedly installed on the right end of the extrusion housing 2 by bolts. The guide sleeve 6 penetrates the right side wall of the extrusion housing 2. An active column 22 coaxially arranged with the extrusion housing 2 is movably installed in the guide sleeve 6. The left end of the active column 22 is fixedly installed by bolts with an extrusion plate 7 located inside the extrusion housing 2. The extrusion plate 7 is circular and matches the inner diameter of the extrusion housing 2. A shovel plate 8 is welded on the left side of the extrusion plate 7. The shovel plate 8 is in the shape of an arc that fits the inner wall of the extrusion housing 2. A driving mechanism is provided on the frame 1 for driving the active column 22 to move and rotate along the guide sleeve 6.

[0026] As Figure 2 shown, the driving mechanism includes a mounting plate 9 driven by a power device and moving left and right along the axial direction of the extrusion housing 2. Two track boxes 10 arranged opposite to each other front and back are provided at the top of the frame 1. The extrusion housing 2 is fixedly installed on the two track boxes 10 by bolts. A sliding groove 11 extending left and right along the axial direction of the extrusion housing 2 is provided on one side of the two track boxes 10 facing each other. The front and rear ends of the mounting plate 9 are respectively fixedly installed by bolts with sliders 12 matching the corresponding sliding grooves 11, so as to improve the stability of the left and right movement of the mounting plate 9. The power device is specifically a cylinder 13. The cylinder body of the cylinder 13 is fixedly installed in the sliding groove 11 by bolts. The piston rod of the cylinder 13 extends to the right along the length direction of the sliding groove 11, and the piston rod of the cylinder 13 is fixedly installed on the corresponding slider 12 by bolts, so as to realize the left and right movement of the mounting plate 9 through the expansion and contraction of the cylinder 13. The right end of the active column 22 is rotatably installed on the mounting plate 9 through a bearing. When the mounting plate 9 moves left and right, it can drive the active column 22 and the extrusion plate 7 to move left and right synchronously. A motor 14 for driving the active column 22 to rotate around its own axis is also installed on the mounting plate 9 by bolts. The rotating shaft of the motor 14 is connected to the active column 22 through a pair of meshing bevel gears 15. The motor 14 can drive the active column 22, the extrusion plate 7 and the shovel plate 8 to rotate synchronously, and at the same time play a role in adjusting the angle of the shovel plate 8.

[0027] When squeezing and dehydrating feces, first, the motor 14 drives the movable column 22 to rotate to adjust the angle of the shovel plate 8, so that the shovel plate 8 rotates to the bottom of the extrusion plate 7. Then, the cylinder 13 extends to drive the mounting plate 9 to move to the right. The mounting plate 9 drives the extrusion plate 7 to move to the right and away from the water-permeable hole 5 through the movable column 22, so that the extrusion plate 7 moves to the position between the feeding port 3 and the discharging port 4, as Figure 5 shown, so that the feces to be dehydrated can smoothly enter the extrusion housing 2 on the side of the feeding port 3 close to the water-permeable hole 5 through the feeding port 3, and at the same time, it can prevent the feces from being discharged directly from the discharging port 4 without dehydration.

[0028] After adding feces into the extrusion housing 2, the cylinder 13 contracts to drive the mounting plate 9 to move to the left. The mounting plate 9 drives the extrusion plate 7 to move to the left and close to the water-permeable hole 5 through the movable column 22 to squeeze the feces, and the water squeezed out from the feces is discharged through the water-permeable hole 5.

[0029] After the feces are squeezed, the cylinder 13 extends to drive the extrusion plate 7 to move to the right until the extrusion plate 7 moves to the right end of the extrusion housing 2. At the same time, the extrusion plate 7 drives the shovel plate 8 to move above the discharging port 4; when the shovel plate 8 is at the bottom of the extrusion plate 7, the extrusion plate 7 can drive the shovel plate 8 to scoop up some feces in the extrusion housing 2 when moving to the left. After the extrusion plate 7 drives the shovel plate 8 to move above the discharging port 4, the motor 14 drives the movable column 22 to rotate to adjust the angle of the shovel plate 8, as Figure 6 shown, so that the shovel plate 8 rotates to the top of the extrusion plate 7, and then the feces scooped up by the shovel plate 8 fall downward through the discharging port 4, thereby improving the discharging efficiency of the dehydrated feces. In addition, in order to further facilitate the discharge of the dehydrated feces in the extrusion housing 2, the extrusion housing 2 can be set in a state where the end with the discharging port 4 is slightly inclined downward.

[0030] After the dehydrated feces are shoveled out of the extrusion housing 2 by the shovel plate 8 multiple times, the cylinder 13 contracts to drive the extrusion plate 7 to move into the end of the extrusion housing 2 close to the water-permeable hole 5, and the motor 14 drives the movable column 22, the extrusion plate 7 and the shovel plate 8 to continuously rotate. The feces remaining on the inner wall of the extrusion housing 2 are scraped off by the shovel plate 8. After scraping, the remaining feces are completely shoveled out by the shovel plate 8, so that the pig feces in the extrusion housing 2 are discharged more cleanly.

[0031] As Figure 4 shown, in order to prevent the shovel plate 8 from hindering the discharge of the squeezed water through the water-permeable hole 5, a plurality of water-permeable holes 16 are evenly distributed on the shovel plate 8.

[0032] In order to improve the scraping effect of the scraping plate 8 on the materials on the inner wall of the extrusion housing 2, scraping portions 17 that can be elastically bent are integrally formed at both circumferential ends of the scraping plate 8, and one end of the scraping portion 17 away from the scraping plate 8 is bent toward the side close to the inner wall of the extrusion housing 2.

[0033] As Figure 3 shown, in order to facilitate the centralized collection of the water squeezed out by feces, a liquid outlet pipe 18 extending vertically is welded to the bottom of the extrusion housing 2, and a plurality of water permeable holes 5 are all located on the bottom wall of the extrusion housing corresponding to the upper end inside the liquid outlet pipe 18. A funnel-shaped collecting trough 19 is provided at the lower end of the liquid outlet pipe 18. The upper end of the collecting trough 19 is fixedly installed at the lower end of the liquid outlet pipe 18 through bolts and is communicated with the liquid outlet pipe 18. A liquid discharge pipe 20 is provided at the lower end of the collecting trough 19.

[0034] In order to prevent the liquid from flowing out through the gap between the extrusion plate 7 and the inner wall of the extrusion housing 2, a sealing ring 21 is embedded on the outer peripheral surface of the extrusion plate 7.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
