The crusher and the existing hammer mill have the following technical problems in actual use: when processing hard materials, it will cause great wear and impact on the screen. If the hard materials are crushed for a long time, the screen is prone to deformation, especially the aperture of the screen may become smaller or cracks may occur. At the same time, hard particles are easy to get stuck in the filter holes of the screen, resulting in material residue, which will increase the load of the screen and cause the screen to deform. In addition, it is difficult to detect a small part of the deformation of the filter in time. If it is not handled in time, it will not only affect the service life of the filter, but also affect the crushing quality. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and provide a kind of agricultural machinery scrap crushing equipment.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A scrap agricultural machinery shredding device comprises an inner frame, a feeding port is arranged at the top of the inner frame, a discharging port is arranged at the bottom of the inner frame, a plurality of groups of hydraulic cylinders are annularly installed on the outer side of the inner frame, an arc-shaped top block is fixedly installed at the telescopic end of the hydraulic cylinder, a filter screen is fixedly installed inside the inner frame, the arc-shaped top block is located between the inner frame and the filter screen, and when the plurality of groups of arc-shaped top blocks are close together, they can be closely attached to the outer side of the filter screen; A crushing shaft is rotatably installed inside the filter screen, and multiple groups of mounting rings are arranged on the outer side of the crushing shaft.

[0006] Furthermore, the guide groove is opened on the inner side of the arc groove away from the hammer rod, and a hydraulic chamber is opened on the other side. The arc-shaped baffle rod can be inserted into the hydraulic chamber. A top spring is arranged between the arc-shaped baffle rod and the guide groove. The internal sealing sliding connection of the hydraulic chamber is connected with a piston top plate. A top spring is arranged between the piston top plate and the hydraulic chamber. The centers of the guide groove and the hydraulic chamber are on the axis of the crushing shaft, and the hydraulic chamber is connected with the external hydraulic system.

DETAILED DESCRIPTION

[0017] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] Embodiment 1, as Figure 1-Figure 8 As shown, a scrap agricultural machinery shredding device includes an inner frame 2, a feeding port 21 is arranged on the top of the inner frame 2, a discharging port 22 is arranged on the bottom of the inner frame 2, multiple groups of hydraulic cylinders 3 are annularly installed on the outer side of the inner frame 2, an arc-shaped top block 4 is fixedly installed on the telescopic end of the hydraulic cylinder 3, a filter screen 5 is fixedly installed inside the inner frame 2, the arc-shaped top block 4 is located between the inner frame 2 and the filter screen 5, and when multiple groups of arc-shaped top blocks 4 are close together, they can be closely attached to the outer side of the filter screen 5; A crushing shaft 6 is rotatably installed inside the filter screen 5, and multiple groups of mounting rings are arranged on the outer side of the crushing shaft 6. An axial hole 63 is opened inside the mounting ring, and four groups of hammer rods 7 are installed inside the axial hole 63. The four groups of hammer rods 7 are distributed in a ring shape, and a torsion spring 71 is arranged between the hammer rod 7 and the mounting ring. Multiple groups of composite crushing hammers are sleeved on the outer side of the hammer rod 7. The composite crushing hammers are located between adjacent mounting rings. The composite crushing hammers are composed of a knife plate 8 and a roller hammer head 81, and the corresponding ends of adjacent roller hammer heads 81 are fitted together. A receiving arc groove 64 is opened inside the mounting ring, and the roller hammer head 81 can swing into the receiving arc groove 64. A guide groove 65 is opened on the inner side of the receiving arc groove 64. An arc-shaped baffle 66 is arranged inside the guide groove 65, and the arc-shaped baffle 66 can slide along the guide groove 65. The arc-shaped baffle 66 is designed to be inclined on the side close to the center of the crushing shaft 6, and the arc-shaped baffle 66 can lock the roller hammer head 81 in the receiving arc groove 64.

[0019] During crushing, the arc-shaped baffle 66 locks the roller hammer 81 in the receiving arc groove 64, and the knife plate 8 is located outside the mounting ring. The material enters the filter screen 5 through the feeding port 21, and the crushing shaft 6 rotates at high speed, which drives the compound crushing hammer to rotate at high speed to crush the material. The crushed material is discharged through the filter screen 5 and the discharge port 22. Since the weight of the roller hammer 81 is greater than the weight of the knife plate 8, the roller hammer 81 will be tightly attached to the arc-shaped baffle 66 under the action of centrifugal force. Therefore, the arc-shaped baffle 66 is controlled to slide along the guide groove 65 through the design of the inclined surface of the arc-shaped baffle 66, and does not separate from the roller hammer 81. The roller hammer 81 will swing outward under the action of the inclined surface, thereby changing the crushing angle of the knife plate 8, thereby changing the distance between the knife plate 8 and the filter screen 5, and changing the crushing distance. No disassembly and adjustment are required, and the adjustment is convenient. After the crushing is completed, the equipment is stopped, and the hydraulic cylinder 3 is controlled to operate. The hydraulic cylinder 3 drives the multiple groups of arc-shaped top blocks 4 to be close together, and the inner sides of the multiple groups of arc-shaped top blocks 4 form the standard shape of the outer side of the filter screen 5. This step squeezes the filter screen 5 that may be convex inward, performs external correction, and makes the deformation amount inward. Then the arc-shaped blocking rod 66 is controlled to slide along the guide groove 65 and disengage from the roller hammer 81. The crushing shaft 6 rotates at a high speed. Since the weight of the roller hammer 81 is greater than the weight of the knife plate 8, the roller hammer 81 will swing to the outside of the mounting ring under the action of centrifugal force. Therefore, the high-speed rolling of the roller hammer 81 can correct the filter screen 5 internally, and the corresponding ends of the adjacent roller hammers 81 fit together, so the filter screen 5 can be completely corrected without missing correction. At the same time, the high-speed roller pressure can be used to roll and crush the hard particles remaining in the filter screen 5. The filter screen 5 can be cleaned while correcting. After rolling for a period of time, the equipment is stopped, and the hydraulic cylinder 3 drives the multiple groups of arc-shaped top blocks 4 away from the filter screen 5, and the equipment performs normal crushing. Therefore, the present invention can greatly improve the service life and crushing quality of the filter screen 5 by performing roller pressing once at intervals, and the roller pressing can be performed during material preparation, which has little impact on the overall production efficiency.

[0020] Embodiment 2, on the basis of the above embodiment, further includes: a guide groove 65 is opened on the inner side of the receiving arc groove 64 away from the hammer rod 7, and a hydraulic chamber 68 is opened on the other side, the arc-shaped baffle rod 66 can be inserted into the hydraulic chamber 68, a top spring 67 is arranged between the arc-shaped baffle rod 66 and the guide groove 65, the internal sealing sliding connection of the hydraulic chamber 68 is connected with a piston top plate 69, a top spring 2 610 is arranged between the piston top plate 69 and the hydraulic chamber 68, the center of the guide groove 65 and the hydraulic chamber 68 is on the axis of the crushing shaft 6, and the hydraulic chamber 68 is connected to the external hydraulic system.

[0021] Furthermore, a hydraulic shaft cavity 611 is provided inside the crushing shaft 6, and the hydraulic shaft cavity 611 is connected to the hydraulic cavity 68. A rotary sealing joint 62 is provided on the right side of the hydraulic shaft cavity 611, and the rotary sealing joint 62 is connected to the external hydraulic system.

[0022] During crushing, the crushing shaft 6 rotates counterclockwise. Figure 7 As shown, the arc-shaped baffle rod 66 will press against the piston top plate 69 under the action of inertia force, and the arc-shaped baffle rod 66 spans the receiving arc groove 64, which can stably lock the roller hammer head 81 in the receiving arc groove 64. At the same time, the internal pressure of the hydraulic chamber 68 is controlled by the external hydraulic system, so that the length of the arc-shaped baffle rod 66 inserted into the hydraulic chamber 68 can be controlled, and the contact position between the roller hammer head 81 and the inclined surface of the arc-shaped baffle rod 66 can be changed, thereby changing the crushing spacing. The control is simple, and the normal operation of the equipment will not be affected during the control, and fine adjustments can be made when the equipment is running. During rolling, the crushing shaft 6 rotates clockwise. Figure 8As shown, the arc-shaped baffle 66 slides in the guide groove 65 under the action of inertia force and squeezes the top spring 67, and the arc-shaped baffle 66 moves away from the roller hammer 81. The crushing shaft 6 rotates at a high speed. Since the weight of the roller hammer 81 is greater than the weight of the blade 8, the roller hammer 81 swings to the outside of the mounting ring under the action of centrifugal force, so the high-speed rolling of the roller hammer 81 can correct the filter screen 5. Through the arrangement of this embodiment, no complicated control structure is required, and the switching between crushing and rolling can be achieved by rotating the crushing shaft 6 clockwise or counterclockwise.

[0023] Embodiment 3, based on the above embodiments, further includes a tilted design of the feed port 21 , through which the overflow of materials from the feed port 21 can be reduced.

[0024] Embodiment 4, on the basis of the above embodiment, further includes that the discharge port 22 is located directly below the middle of the two groups of arc-shaped top blocks 4 at the bottom. Through this design, during crushing, the hydraulic cylinder 3 drives the arc-shaped top block 4 away from the filter screen 5, and the moving trajectory is on the radial line of the filter screen 5. Therefore, the bottom arc-shaped top blocks 4 will also move away from each other, forming a material discharge space between them, so that the crushed material can be better discharged through the material port. At the same time, there is a distance between adjacent arc-shaped top blocks 4, and there is also a distance between the arc-shaped top blocks 4 and the inner wall of the outer frame 1, to ensure that no material will accumulate on the arc-shaped top blocks 4.

[0025] Embodiment 5, based on the above embodiment, further includes that an outer frame 1 is arranged outside the inner frame 2, and the sealing performance of the device can be greatly guaranteed by the arrangement of the double-layer frame.

[0026] Furthermore, outer shaft frames 11 are fixedly installed on both sides of the outer frame 1, the crushing shaft 6 passes through the outer frame 1 and is rotatably installed in the outer shaft frame 11, and a transmission pulley 61 is fixedly installed on the left side of the crushing shaft 6. The transmission pulley 61 is located on the outside of the outer shaft frame 11, and the rotation of the crushing shaft 6 is more stable.

[0027] Embodiment 6, based on the above embodiments, further includes that the rolling hammer head 81 is designed to be cylindrical. Through the design of this embodiment, the rolling effect can be improved.

[0028] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
