However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0025] Example 1

[0026] like Figure 1-Figure 6 A new type of crushing device for producing high-efficiency organic fertilizer from animal manure mainly includes a crushing box 1, a crushing roller 2 and a motor 3.

[0027] A crushing roller 2 is rotatably connected in the crushing box 1, and a motor 3 drives the crushing roller 2 to rotate through a conveyor belt structure, a gear structure, etc.

[0028] For example, there can be two crushing rollers 2, one of which is fixed to gear 1 and pulley 1, and the other is fixed to gear 2. The motor 3 is arranged on one side of the crushing box 1, and pulley 2 is fixed on the output shaft of the motor 3. A transmission belt is connected between pulley 1 and pulley 2, and gear 1 and gear 2 are meshed for transmission. In this way, the rotation of the motor 3 can simultaneously drive the two crushing rollers 2 to rotate in opposite directions, so as to squeeze and crush the feces entering the crushing box 1.

[0029] The above structure is prior art, so it is only briefly explained without further elaboration.

[0030] The crushing roller 2 includes a roller body 21, a threaded sleeve 22, and a cutting knife 24. The roller body 21 is used to be fixedly connected to the corresponding gear 1 and pulley 1. The roller body 21 includes a connecting ring and a blade. The blade is fixed to the outside of the connecting ring. The staggered movement between the blades on the two roller bodies 21 can achieve the purpose of crushing feces; a plurality of placement grooves are opened in the connecting ring along the axial direction of the roller body 21. The blade body of the cutting knife 24 is elastically rotatably connected to the side wall of the placement groove. If there is no external force interference, the elastic force will drive the cutting knife 24 to tilt up and be higher than the blade; the inner wall of the roller body 21 is threadedly connected to the threaded sleeve 22, and a buckle 1 is fixed on one end of the cutting knife 24. The threaded sleeve 2 2 is correspondingly fixed with a buckle 2, and the buckle 1 can be engaged with the buckle 2. When the buckle 1 and the buckle 2 are engaged together, the cutting knife 24 overcomes the elastic force and retracts into the placement groove, which does not affect the normal crushing activity of the two roller bodies 21. When the straw is wound around the roller body 21 to a certain extent, the motor 3 is turned off to keep the two roller bodies 21 relatively still. At this time, the user rotates the threaded sleeve 22 relative to the roller body 21 to move the threaded sleeve 22 on the inner side of the roller body 21 to remove the buckle 2 from the buckle 1. At this time, the cutting knife 24 has no external resistance and is tilted under the action of the spring, and uses the elastic force of the spring to cut the straw wound around the outer side of the roller body 21.

[0031] It should be noted that the cutting knives 24 on the two roller bodies 21 are arranged at positions that do not interfere with each other when they are ejected.

[0032] Furthermore, because the receiving groove is in the shape of an elongated strip, rubber sheets 25 are fixed on both sides of the elongated strip, and the two rubber sheets 25 are arranged alternately, one high and one low. When the cutting knife 24 is located below the rubber sheet 25, the blocking effect of the rubber sheet 25 can prevent feces from entering the interior of the roller body 21 through the receiving groove. When the cutting knife 24 is tilted, the deformation characteristics of the rubber sheet 25 itself will not cause excessive interference to the cutting knife 24, until the cutting knife 24 retracts into the receiving groove again, and the two rubber sheets 25 return to the alternate arrangement state of one high and one low.

[0033] Preferably, the threaded sleeve 22 is located outside the crushing box 1 to facilitate operation by the user.

[0034] Example 2

[0035] like Figure 1-Figure 6On the basis of Example 1, in order to solve the problem that the opened cutting knife 24 is difficult to retract into the placement groove, the present solution further designs a rotating rod 23, which is inserted into the threaded sleeve 22, and the roller body 21 and the rotating rod 23 are elastically rotatably connected, and one end of the cutting knife 24 and the rotating rod 23 are bound by a rope. When the cutting knife 24 is opened, the rope is generally in a taut state, and when the cutting knife 24 is closed, the rope is in a relaxed state. During the specific operation, the rotating rod 23 is rotated relative to the roller body 21 and the threaded sleeve 22. During the rotation of the rotating rod 23, the cutting knife 24 is pulled by the rope, so that the cutting knife 24 overcomes the elastic force and gradually retracts into the accommodation groove. When the cutting knife 24 completely enters the accommodation groove, the threaded sleeve 22 is rotated relative to the roller body 21 and the rotating rod 23, so that the second buckle is fastened to the first buckle to lock the cutting knife 24. In this way, the cutting knife 24 can be opened to remove the straw when necessary, and the cutting knife 24 can be retracted into the accommodation groove again after the straw is removed, so as to achieve the purpose of repeated use.

[0036] Preferably, the rotating rod 23 is located outside the crushing box 1 so as to be easy for the user to operate.

[0037] Preferably, the rotating rod 23 and the threaded sleeve 22 can be arranged on the outside of the crushing box 1 in the same direction, so that one end of the roller body 21 is used for driving contact with the motor 3, and the other end is convenient for users to operate.

[0038] The elastic connection between the roller body 21 and the rotating rod 23 allows the rotating rod 23 to rotate back to its original position after the user removes the external force and the cutting knife 24 is locked, thereby preventing the rotating rod 23 from rotating when the cutting knife 24 bounces up instantly. This design allows the cutting knife 24 to make threatening movements inside the crushing box 1 during the process of cutting straw, thereby improving the safety of the entire device operation.

[0039] Preferably, a plurality of threading grooves are provided on the threaded sleeve 22, through which the wire rope passes. This ensures the firmness of the threaded sleeve 22 and improves the stability of the threaded sleeve 22 locking the cutting blade 24 while allowing the wire rope to move freely.

[0040] It can be known that by arranging a plurality of cutting knives 24 on the roller body 21, the purpose of removing straw from the entire roller is achieved.

[0041] In summary, the technical solution of the present application can be briefly described as: using the threaded sleeve 22 to reasonably control the pop-up time of the cutting knife 24, allowing the cutting knife 24 to pop out when necessary to cut straw and other materials wrapped around the roller body 21, and using the rotation of the rotating rod 23 to control the cutting knife 24 to retract into the roller body 21, so as to achieve the purpose of repeatedly opening and closing the cutting knife 24.
