Technical Field
[0001] The present invention relates to the technical field of excrement treatment, in particular to a sheep breeding excrement treatment device. Background Art
[0002] Sheep manure is black, oval-shaped, and generally about the size of soybeans. It's a versatile animal waste. Fermented, it's a valuable organic fertilizer, improving soil quality and preventing soil compaction. It's also economically valuable. It's commonly used for growing flowers, pasture, and tea.
[0003] Sheep manure needs to be collected before fermentation. For some small sheep farmers, using large manure removal vehicles is costly. Currently, manure removal in sheep sheds is typically done manually with shovels or brooms, which not only places a heavy physical strain on workers but is also inefficient, time-consuming, and labor-intensive.
[0004] Therefore, we propose a sheep breeding manure treatment device to solve the above problems. Summary of the Invention
[0005] The object of the present invention is to provide a sheep breeding manure treatment device which is simple to operate and has high collection efficiency.
[0006] The present invention is achieved by the following measures:
[0007] A sheep breeding manure treatment device, characterized by comprising a collection box, wherein a collection mechanism is provided in the collection box;
[0008] The bottom surface of the collection box is set to be open;
[0009] The collecting mechanism comprises a pair of vertically arranged chutes, the pair of chutes being respectively arranged on the left and right sides of the collecting box, and matching slides being slidably arranged in the chutes on both sides, and a picking portion being arranged between the slides on both sides;
[0010] The picking part includes a mounting plate, which is arranged between the slides on both sides. A number of circular needles are provided on the lower side of the mounting plate. When the mounting plate slides downward, the circular needles pierce the sheep manure on the floor of the sheep house. Then, the mounting plate slides downward to bring the sheep manure into the collection box for collection.
[0011] The specific features of the present invention also include:
[0012] A screw rod is rotatably arranged in the slide groove on one side, and the slide plate on the corresponding side is arranged on the periphery of the screw rod through a threaded structure. A motor is arranged on the top surface of the collection box, and the upper end of the screw rod passes through the top surface of the collection box and is arranged on the output end of the motor. The screw rod is driven to rotate by the motor, thereby driving the mounting plate to move up and down, that is, driving several of the circular needles to move up and down.
[0013] Two slides are horizontally arranged on the left and right side surfaces of the collection box, a pair of the two slides are located near the opening at the lower side of the collection box and are arranged on one side of the one slide, and matching slides are slidably arranged in the two slides on both sides, and an inner collection box for use with the picking part is arranged between the two slides on both sides, and the two slides on both sides are close to the side of the inner collection box away from the picking part, and the inner collection box is a box body with an opening on the upper side, and the width of the inner collection box is greater than the width of the picking part, so as to avoid sheep manure spilling on the outside of the inner collection box during collection.
[0014] The collecting mechanism also includes a linkage mechanism;
[0015] The linkage mechanism includes three groups of rollers arranged on the inner side of the collection box, and a closed transmission belt is arranged on the periphery of the three groups of rollers. The transmission belt after assembly is in the shape of a right triangle, and the transmission belt can be a V-belt. The corresponding side surface of the inner collection box is fixed to the lower side surface of the transmission belt of the horizontal section by a fixing member, and the fixing member is provided at one end of the side surface of the inner collection box away from the picking portion;
[0016] A fixing plate is provided on the outer side of the transmission belt of the vertical section, a round rod is provided on the fixing plate, a limiting plate is provided on the side of the corresponding collection box, a guide hole is provided on the limiting plate that cooperates with the round rod, the round rod is slidably arranged in the guide hole, a spring 1 is provided on the periphery of the round rod between the limiting plate and the fixing plate, one end of the spring 1 is provided on the limiting plate, and the other end of the spring 1 is provided on the fixing plate, a top plate used in conjunction with the fixing plate is provided on the corresponding side of the mounting plate, and the top plate is located directly below the fixing plate. When the picking part slides upward, the top plate presses against the lower side of the fixed plate, thereby driving the transmission belt to slide along the three groups of rollers, and at the same time the round rod moves upward along the guide hole. At this time, the transmission belt drives the inner collecting box to slide below the picking part through the fixing member. By reasonably designing the length of the transmission belt, it is possible to achieve that the inner collecting box slides to the right under the picking part during the upward movement of the picking part. When the picking part moves downward, the inner collecting box is reset under the action of the spring 1, and a limiting circular plate is provided on the top end of the corresponding round rod;
[0017] When the pick-up box is lifted up, the pick-up box is lifted up and the pick-up box is lifted up, so the pick-up box is lifted up and the pick-up box is lifted up. When the pick-up box is lifted up, the pick-up box is lifted up and the pick-up box is lifted up, so the pick-up box is lifted up and the pick-up box is lifted up. When the pick-up box is lifted up, the pick-up box is lifted up and the pick-up box is lifted up, so the pick-up box is lifted up and the pick-up box is lifted up.
[0018] An opening is provided on the top surface of the collecting box and is matched with the round rod.
[0019] A chute three is provided on the side surfaces on both sides of the collection box, and the chute three is provided on the other side of the chute one away from the chute two, and a slide plate three is slidably provided between the chute three on both sides, and a pressure plate is provided on one side of the slide plate three, and a plurality of through holes cooperating with the circular needles are provided on the pressure plate, and a plurality of the through holes are slidably sleeved on the outer periphery of the corresponding circular needles;
[0020] When the pick-up part moves up, the pressing plate will move down together with the pressing plate, and the spring 2 will compress the spring 2. When the pick-up part moves up so that the inner collecting box is just under the pick-up part, the slide 3 will just move to the upper end of the slide 3 under the action of the spring 2. Then, the pick-up part continues to move up a distance. At this time, the pressing plate will press down the sheep manure inserted on the circular needle, and the sheep manure will fall into the inner collecting box below. The width of the inner collecting box should be greater than the width of the pick-up part. In this way, although the pick-up part continues to move up a distance, the pick-up part is always within the range of the inner collecting box to prevent the sheep manure from falling outside the inner collecting box.
[0021] A filter plate is provided in the middle of the inner collecting box. The filter plate includes a flat plate. The flat plate is provided with a number of filter holes that allow sheep manure to pass through. Since there are weeds and other materials on the ground of the sheep house, it is inevitable that weeds will be picked up when the picking part picks up the sheep manure. The filter plate can leave the weeds on it and then be cleaned manually.
[0022] A plurality of soft plastic strips with a certain width are arranged around the mounting plate, and the plurality of plastic strips form a fence. When the pressing plate presses the sheep manure, the sheep manure falls in the fence, which can prevent the sheep manure from falling outside the inner collecting box.

An inclined plate is provided below the inner collecting box and connected to the lower side of the opening, and the other side of the inclined plate extends to near the picking part. The bottom surface of the corresponding inner collecting box is set to an inclined structure inclined in the same direction as the inclined plate, and an opening 2 is provided on the corresponding side of the inner collecting box. After passing through the filter hole, the sheep manure falls on the bottom surface of the inner collecting box, then rolls down along the inclined structure, falls on the inclined plate through the opening 2, and then rolls down into the outer collecting box through the opening 1, finally completing the collection of the sheep manure.
[0024] A plurality of rollers are provided on the lower side of the collecting box to facilitate the movement of the entire device.
[0025] A push rod is provided on one side of the collection box for pushing the movement of the entire device;
[0026] A door is hinged on the side of the collecting box, through which the weeds on the filter plate can be cleaned.
[0027] When the device is in use, the push rod pushes the device to move, and then the motor is controlled to move the picking part downward, and the sheep manure on the ground is pricked by the circular needle. Then, the motor controls the picking part to move upward. When the inner collecting box slides to the bottom of the picking part, the pressing plate presses the sheep manure down, and the sheep manure falls into the inner collecting box. Then, the sheep manure passes through the filter hole, the second opening, the inclined plate and the first opening in sequence into the outer collecting box, and the collection is completed.
[0028] The beneficial effects of the present invention are: the device has a simple structure, is easy to use, and can collect sheep manure quickly and effectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figure 1-7 , a sheep breeding manure treatment device, comprising a collecting box 1, wherein a collecting mechanism is provided in the collecting box 1;
[0042] The bottom surface of the collection box 1 is set to be open;
[0043] The collecting mechanism includes a pair of vertically arranged chutes 9, which are respectively arranged on the left and right side surfaces of the collecting box 1. A matching slide 28 is slidably arranged in each of the chutes 9 on both sides, and a picking portion is provided between the slides 28 on both sides.
[0044] The picking part includes a mounting plate 8, which is arranged between two side slides 28. A number of circular needles 27 are provided on the lower side of the mounting plate 8. The mounting plate 8 slides downward, and the number of circular needles 27 penetrate into the sheep manure on the ground of the sheep house. Then, the mounting plate 8 slides downward to bring the sheep manure into the collection box 1 for collection.
[0045] A screw rod 24 is rotatably provided in a side slide groove 9, and a corresponding side slide plate 28 is provided on the periphery of the screw rod 24 through a threaded structure. A motor 2 is provided on the top surface of the collection box 1. The upper end of the screw rod 24 passes through the top surface of the collection box 1 and is provided on the output end of the motor 2. The screw rod 24 is driven to rotate by the motor 2, thereby driving the mounting plate 8 to move up and down, that is, driving a plurality of circular needles 27 to move up and down.
[0046] A chute 25 is horizontally arranged on the left and right side surfaces of the collection box 1. A pair of chutes 25 are located on the lower side of the collection box 1 close to the opening and are arranged on one side of the chute 1 9. A matching slide 21 is slidably arranged in the chute 25 on both sides. An inner collection box 17 for use in conjunction with the picking part is arranged between the slides 21 on both sides. The slides 21 on both sides are close to the side of the inner collection box 17 away from the picking part. The inner collection box 17 is a box body with an opening on the upper side. The width of the inner collection box 17 is greater than the width of the picking part, so that sheep manure can be prevented from being spilled on the outside of the inner collection box 17 during collection.
[0047] Collection agencies also include linkage agencies;
[0048] The linkage mechanism includes three sets of rollers 15 arranged on the inner side of the collection box 1. A closed transmission belt 14 is arranged around the three sets of rollers 15. The assembled transmission belt 14 is in the shape of a right triangle. The transmission belt 14 can be a V-belt. The corresponding side surfaces of the inner collection box 17 are fixed to the lower side surface of the transmission belt 14 in the horizontal section by fixing members 20. The fixing members 20 are arranged on the side surface of the inner collection box 17 away from the picking portion.
[0049] A fixed plate 30 is provided on the outer side of the transmission belt 14 of the vertical section, and a round rod 10 is provided on the fixed plate 30. A limiting plate 11 is provided on the side of the corresponding collection box 1. The limiting plate 11 is provided with a guide hole that cooperates with the round rod 10. The round rod 10 is slidably set in the guide hole. A spring 12 is provided on the periphery of the round rod 10 between the limiting plate 11 and the fixed plate 30. One end of the spring 12 is provided on the limiting plate 11, and the other end of the spring 12 is provided on the fixed plate 30. A top plate 26 used in conjunction with the fixed plate 30 is provided on the corresponding side of the mounting plate 8. The top plate 26 is located at the fixed Directly below the fixed plate 30, when the picking part slides upward, the top plate 26 presses against the lower side of the fixed plate 30, thereby driving the transmission belt 14 to slide along the three sets of rollers 15, and at the same time the round rod 10 moves upward along the guide hole. At this time, the transmission belt 14 drives the inner collection box 17 to slide downward to the picking part through the fixing member 20. By reasonably designing the length of the transmission belt 14, it is possible to achieve that the inner collection box 17 slides to the right below the picking part during the upward movement of the picking part. When the picking part moves downward, the inner collection box 17 is reset under the action of the spring 12, and a limiting circular plate is provided on the top of the corresponding round rod 10;
[0050] In the initial state, the inner collecting box 17 is displaced to one side of the picking part and is just close to the picking part. When the picking part moves up to the point where the lower end of the circular needle 27 is higher than the upper end of the inner collecting box 17, the top plate 26 is pressed against the lower side of the fixing plate 30. Then, the picking part pushes the fixing plate 30 to slide the transmission belt 14, thereby driving the inner collecting box 17 to move downwardly toward the picking part. At this time, the length of the transmission belt 14 in the horizontal section is required to be greater than the front and rear width of the picking part, so as to ensure that the inner collecting box 17 can slide to the bottom of the picking part. When the inner collecting box 17 reaches the bottom of the picking part, a limit rod can be set for the picking part at this position to prevent it from moving up any more, or a corresponding sensor can be set to automatically stop the motor 2.
[0051] An opening 3 is provided on the top surface of the collecting box 1 to cooperate with the round rod 10 .
[0052] A chute 3 23 is provided on the side surfaces on both sides of the collection box 1. The chute 3 23 is provided on the other side of the chute 1 9 away from the chute 2 25. A slide 3 7 is slidably provided between the chute 3 23 on both sides. A pressure plate 29 is provided on one side of the slide 3 7. The pressure plate 29 is provided with a plurality of through holes that cooperate with the circular needles 27. The plurality of through holes are slidably sleeved on the outer periphery of the corresponding circular needles 27.
[0053] When the picking portion moves up, the pressing plate 29 moves down together with the pressing plate 29, and the spring 21 is compressed. When the picking portion moves up so that the inner collecting box 17 is just below the picking portion, the sliding plate 37 moves to the upper end of the sliding groove 3 23 under the action of the spring 21. Then, the picking portion continues to move up a distance. At this time, the pressing plate 29 will press the sheep manure inserted on the circular needle 27 down, and the sheep manure will fall into the inner collecting box 17 below. The width of the inner collecting box 17 should be greater than the width of the picking portion. In this way, although the picking portion continues to move up a distance, the picking portion is always within the range of the inner collecting box 17, preventing the sheep manure from falling outside the inner collecting box 17.
[0054] A filter plate 16 is provided in the middle of the inner collecting box 17. The filter plate 16 includes a flat plate with a plurality of filter holes for allowing sheep manure to pass through. Since there are weeds and other materials on the ground of the sheep house, it is inevitable that weeds will be picked up when the picking part picks up the sheep manure. The filter plate 16 can leave the weeds on it and then be cleaned manually.
[0055] Several soft plastic strips 13 of a certain width are arranged around the mounting plate 8. The several plastic strips 13 form a fence. When the pressing plate 29 presses the sheep manure, the sheep manure falls in the fence, which can prevent the sheep manure from falling outside the inner collection box 17.
[0056] An outer collecting box 6 is provided on the outside of the collecting box 1, and an opening 1 connected to the outer collecting box 6 is provided on the corresponding side of the collecting box 1. An inclined plate 19 is provided below the inner collecting box 17 and connected to the lower side of the opening. The other side of the inclined plate 19 extends to near the picking part, and the bottom surface of the corresponding inner collecting box 17 is set to an inclined structure inclined in the same direction as the inclined plate 19, and an opening 2 18 is provided on the corresponding side of the inner collecting box 17. After passing through the filter hole, the sheep manure falls on the bottom surface of the inner collecting box 17, and then rolls down along the inclined structure, falls on the inclined plate 19 through the opening 2, and then rolls down into the outer collecting box 6 through the opening 1, and finally completes the collection of the sheep manure.
[0057] A number of rollers are provided on the lower side of the collecting box 1 to facilitate the movement of the entire device.
[0058] A push rod 5 is provided on one side of the collection box 1 to push the entire device to move;
[0059] A door 4 is hinged on the side of the collecting box 1, through which weeds on the filter plate 16 can be cleaned.
[0060] When the device is in use, the push rod 5 is used to push the device to move, and then the motor 2 is controlled to move the picking part downward, and the sheep manure on the ground is picked up by the circular needle 27. Then, the motor 2 is used to control the picking part to move upward. When the inner collecting box 17 slides to the bottom of the picking part, the pressing plate 29 will press the sheep manure down, and the sheep manure falls into the inner collecting box 17. Then, the sheep manure passes through the filter hole, the second opening 18, the inclined plate 19 and the first opening in sequence into the outer collecting box 6 to complete the collection.
[0061] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
