Description

Technical Field

[0001] The invention relates to the field of beef cattle breeding equipment, and in particular to a complete set of equipment for returning beef cattle breeding manure to fields. Background Art

[0002] With the development of large-scale and intensive cattle breeding, the environmental pollution caused by the concentrated discharge of cattle manure has become increasingly prominent. Cow manure itself is a biomass resource, containing a large number of mineral elements and rich nutrients. Therefore, after harmless treatment, it can be used to return to the fields, which is beneficial to improving soil fertility, restoring farmland ecology, and increasing farmland productivity, which is of great significance to ensuring the sustainable development of agriculture.

[0003] At present, for the cleaning of cow dung, manual or mechanical devices are mostly used to scoop up the cow dung, then transfer it to intermediate storage equipment, transmission equipment and other devices, send the cow dung to a grinder for grind, and then spray the grinded cow dung back to the field through a sprayer.

[0004] However, for cattle farms with hilly terrain and much gravel, cow dung may be located on the top of a mound or at the bottom of a pit when it is formed, or the gravel may be mixed with the solidified cow dung. The shovel cannot scoop up the cow dung on the top of a mound or at the bottom of a pit all at once, and the cow dung that is not scooped up may be pushed away or thrown away, increasing the difficulty of collection. The cow dung mixed with gravel cannot be cleaned up and put into subsequent equipment together, which may damage the equipment. Summary of the invention

[0005] The invention provides a complete set of equipment for returning cattle manure to fields, so as to solve the problem in the prior art that cattle manure from cattle breeding in hilly areas is difficult to collect.

[0006] To achieve the above object, the present invention provides the following solutions:

[0007] A complete set of equipment for returning manure from beef cattle breeding to fields, comprising a collecting device, a processing device, a storage bin and a returning device connected in sequence by a conveying device, the collecting device comprising a mobile vehicle, a manure collecting claw installed on the mobile vehicle and a visual positioning device for positioning manure, the manure collecting claw comprising an outer telescopic rod, an inner telescopic rod installed inside the outer telescopic rod and a plurality of lateral telescopic rods arranged at the end of the outer telescopic rod, one end of the lateral telescopic rod is connected to the lower end of the inner telescopic rod, and the other end is arranged away from the axis of the inner telescopic rod, when the inner telescopic rod rises, the lateral telescopic rod contracts toward the axis direction of the outer telescopic rod, and when the inner telescopic rod descends, the lateral telescopic rod extends in a direction away from the axis of the outer telescopic rod.

[0008] The present invention locates cow dung by a mobile vehicle and a visual positioning device, and then collects the cow dung by a dung collecting claw, which is simple and quick. In addition, an outer telescopic rod is inserted into the cow dung, the inner telescopic rod is extended and shortened, a lateral telescopic rod is inserted into the cow dung for limiting, and the lateral telescopic rod is retracted to make the cow dung fall. The problem that it is difficult to clean the cow dung with a shovel due to uneven ground in hilly areas can be solved, and the problem of collecting gravel on the ground when the shovel collects the cow dung is avoided, so that the gravel can be prevented from damaging the equipment.

[0009] Furthermore, the feces collecting claw also includes a plurality of claw teeth rotatably connected to the side wall of the outer telescopic rod, and the upper ends of the claw teeth are connected to the inner telescopic rod.

[0010] Since the outer telescopic rod needs to be inserted into the cow dung, the thick outer telescopic rod can easily break the cow dung and affect the grasping. Therefore, the diameter of the outer telescopic rod is limited, resulting in the limited length of the lateral telescopic rod, which can easily lead to the problem that although the lateral telescopic rod is extended, it is still unable to prevent the cow dung from falling. Through the claws rotatably connected to the side wall of the outer telescopic rod, when the outer telescopic rod is inserted into the cow dung, multiple claws clamp the cow dung from all sides, which adds multiple force points for grasping the cow dung and prevents the cow dung from falling.

[0011] Furthermore, a cavity is provided in the outer telescopic rod, the upper end of the claw tooth extends into the cavity, a plurality of fixed pulleys are installed in the cavity, a connecting rope is provided at the upper end of the claw tooth, and the connecting rope is connected to the inner telescopic rod after passing through the fixed pulley. When the inner telescopic rod rises, the end of the claw tooth rotates in a direction away from the outer telescopic rod, and when the inner telescopic rod descends, the end of the claw tooth rotates in a direction close to the outer telescopic rod.

[0012] The claws are connected to the inner telescopic rod through a fixed pulley and a connecting rope, so that the inner telescopic rod can control the claws and the lateral telescopic rod at the same time, so that a linkage is formed between the claws and the lateral telescopic rod, that is, when the inner telescopic rod is extended, the claws are closed, and the lateral telescopic rod is extended, and the cow dung is limited together; when the inner telescopic rod is shortened, the claws are opened, and the lateral telescopic rod is shortened, so that the limitation of the cow dung clamped on the outer telescopic rod is cancelled, and the cow dung falls off.

[0013] Furthermore, the feces collecting claw also includes a bendable plate connecting the lateral telescopic rod and the inner telescopic rod, a limit rod is provided above the bending portion of the bendable plate, and an arc-shaped guide is provided below the bending portion of the bendable plate.

[0014] With respect to the feces collecting claw, since the inner telescopic rod telescopes and moves radially along the feces collecting claw, and the lateral telescopic rod telescopes and moves perpendicularly to the axis of the feces collecting claw, the telescopic directions are different, but they need to be telescoped and extended at the same time. Therefore, the inner telescopic rod and the lateral telescopic rod are connected by a flexible plate, so that the inner telescopic rod and the lateral telescopic rod can transmit radial force while telescoping in different directions. The limit rod is used to limit the bending portion of the flexible plate, and the arc-shaped guide member is used to guide the bending portion of the flexible plate.

[0015] Furthermore, a plurality of limiting grooves are provided on the side wall of the outer telescopic rod, and the lateral telescopic rod is installed in the limiting grooves, and the lateral telescopic rod corresponds to the limiting grooves one by one.

[0016] The limiting groove is used to accommodate the lateral telescopic rod and to limit the lateral telescopic rod laterally to prevent the lateral telescopic rod from lateral deviation or rotation.

[0017] Furthermore, the conveying device includes a conveyor belt and a telescopic receiving plate installed at the initial end of the conveyor belt, the telescopic receiving plate is arranged at an angle, the lower end of the telescopic receiving plate is located above the conveyor belt, and the upper end of the telescopic receiving plate is extended and located on the moving path of the feces collecting claw.

[0018] When the mobile vehicle is moving, it detects cow dung through the visual positioning device, grabs the cow dung and transfers it to the top of the conveyor belt by extending and shortening the dung collecting claws, and guides the cow dung to the conveyor belt for transfer by extending the telescopic receiving plate.

[0019] Furthermore, the processing device includes a telescopic baffle installed above the conveyor belt, and a plurality of conical baffles are arranged at equal intervals below the telescopic baffle, and the conical angle of the conical baffle is facing the direction opposite to the transmission direction of the conveyor belt.

[0020] The cow dung is blocked on the conveyor belt by extending the telescopic baffle, and the cow dung is broken by the cutting of the conical baffle by utilizing the relative movement between the conveyor belt and the telescopic baffle. At the same time, since gravel may be mixed in the cow dung when it is formed, the gap between the conical baffles can also block the gravel in the cow dung whose diameter is larger than the gap width, so as to prevent it from entering the subsequent process and causing damage to the equipment.

[0021] Furthermore, the processing device also includes a telescopic guide plate installed above the conveyor belt, and the telescopic guide plate is installed on a side of the telescopic baffle away from the initial end of the conveyor belt.

[0022] When the conical baffle collects the gravel, in order to prevent too much gravel from blocking the passage of cow dung, after the last piece of cow dung is sent away by the conveyor belt, the telescopic baffle is raised and the telescopic guide plate is lowered, so that the gravel blocked by it moves along the conveyor belt, and then is blocked by the telescopic guide plate and guided to leave the conveyor belt; and when the conical baffle crushes the cow dung, the telescopic guide plate can also be lowered to adjust the gap between the telescopic guide plate and the conveyor belt to further crush the cow dung and allow the crushed cow dung to pass through while blocking the gravel with a diameter greater than the gap width between the telescopic guide plate and the conveyor belt and less than the gap width between the conical baffles from passing.

[0023] Furthermore, a plurality of spikes are evenly arranged on the surface of the conveyor belt, which are used to increase the friction between the cow dung and the conveyor belt, and can also play a role in breaking up the cow dung to a certain extent.

[0024] Furthermore, side guard plates are provided on both sides of the conveyor belt to prevent the crushed cow dung from falling out of the conveyor belt.

[0025] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0026] (1) The present invention locates cow dung by using a mobile vehicle and a visual positioning device, and then collects the cow dung by using a dung collecting claw, which is simple and quick. In addition, the outer telescopic rod is inserted into the cow dung, the inner telescopic rod is extended and shortened, the lateral telescopic rod is inserted into the cow dung for limiting, and the lateral telescopic rod is retracted to make the cow dung fall. This can solve the problem that it is difficult to clean cow dung with a shovel due to the uneven ground in hilly areas. At the same time, it also avoids the problem that the shovel collects gravel on the ground when collecting cow dung, thereby preventing the gravel from damaging the equipment.

[0027] (2) Through the claws rotatably connected to the side wall of the outer telescopic rod, when the outer telescopic rod is inserted into the cow dung, multiple claws clamp the cow dung from all sides, adding multiple force points for grabbing the cow dung and preventing the cow dung from falling;

[0028] (3) The claws are connected to the inner telescopic rod through a fixed pulley and a connecting rope, so that the inner telescopic rod can simultaneously control the claws and the lateral telescopic rod, so that the claws and the lateral telescopic rod are linked, that is, when the inner telescopic rod is extended, the claws are closed and the lateral telescopic rod is extended, and the cow dung is limited together; when the inner telescopic rod is shortened, the claws are opened and the lateral telescopic rod is shortened, canceling the limit of the cow dung clamped on the outer telescopic rod, so that the cow dung falls off;

[0029] (4) The cow dung is blocked on the conveyor belt by extending the telescopic baffle, and the cow dung is broken by the cutting of the conical baffle by utilizing the relative movement between the conveyor belt and the telescopic baffle. At the same time, since the cow dung may be mixed with gravel when it is formed, the gap between the conical baffles can also block the gravel in the cow dung with a diameter larger than the gap width, preventing it from entering the subsequent process and causing damage to the equipment.
