DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions, and advantages of the present technology clearer, the present technology will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present technology.

[0035] As shown in Figures 1-8 The present embodiment proposes a reed and straw wall-breaking pulverizing device, which comprises an introduction channel 10 and a pulverizing assembly 20. The pulverizing assembly 20 is in a cylindrical shape, and the introduction channel 10 is horizontally arranged. The first end of the introduction channel 10 is a feeding end, and the second end of the introduction channel 10 is a discharging end. The second end of the introduction channel 10 is connected to the feeding port of the pulverizing assembly 20. The feeding port of the introduction channel 10 is arranged at the top of the first end of the introduction channel 10. The pulverizing assembly 20 has a blade assembly inside for breaking rod-shaped crops. The blade assembly is arranged in an inclined manner to form a guide fan state. After the rod-shaped crops are fed into the introduction channel 10 from the feeding port, they are sucked into the pulverizing assembly 20 by negative pressure to complete the breaking of the rod-shaped crops.

[0036] The main body of the introduction channel 10 is arranged in an inclined manner. The inclination angle of the main body of the introduction channel 10 is 1°-10°. The second end of the introduction channel 10 is higher than the first end of the introduction channel 10. The end face of the first end of the introduction channel 10 is covered with a first air-permeable net 12. The inner wall of the bottom side of the introduction channel 10 is provided with a separation protrusion 13 near the second end for preventing impurities from entering the pulverizing assembly 20.

[0037] Specifically, in the embodiment, the reed and straw are collectively referred to as rod-shaped crops. Before the rod-shaped crops are fed into the feeding pipe 11 of the introduction channel 10, the rod-shaped crops are first cut into short rods with a length of 8-15 cm by the cutting device at the front end. After the rod-shaped crops are fed into the feeding pipe 11, the blade assembly is arranged in a form of a flow guide fan due to the inclination, and the rotation of the blade assembly can form a gas flow inside the crushing assembly 20 and the introduction channel 10 connected thereto. Part of the gas in the introduction channel 10 enters the introduction channel 10 from the feeding pipe 11, and part of the gas passes through the first air-permeable net 12 and is sucked into the introduction channel 10 by the first air-permeable net 12. The direction of the gas flow is shown by the arrow in Figure 1 .

[0038] In this process, if stones or other heavy impurities such as metal products are mixed into the rod-shaped crops, the impurities will fall to the bottom of the introduction channel 10 and be removed by the impurity-removing protrusion 13, and the rod-shaped crops with a small density and a light weight will be sucked into the crushing assembly 20 for crushing.

[0039] In the embodiment, the crushing assembly 20 is a tilted cylindrical structure. The purpose of arranging the crushing assembly 20 in this way is to reduce the overall height of the crushing device, and the flow of the rod-shaped crops can be driven in a pneumatic manner. The crushing assembly 20 arranged in a tilted manner can also achieve the purpose of removing impurities similar to the introduction channel 10 described above. In the embodiment, the first end of the crushing assembly 20 is the feeding end, the second end is the discharging end, and the height of the first end of the crushing assembly 20 is lower than that of the second end. The output end of the introduction channel 10 is connected to the upper position of the first end of the crushing assembly 20.

[0040] In other embodiments, the crushing assembly 20 can be arranged vertically, which has the advantage of quickly discharging the crushed rod-shaped crops. In this embodiment, the upper end of the crushing assembly 20 is the feeding end, the lower end of the crushing assembly 20 is the discharging end, and the output end of the introduction channel 10 is connected to the position close to the upper end of the outer surface of the crushing assembly 20.

[0041] As shown in Figure 2 , the crushing assembly 20 includes a crushing cylinder 21, a driving motor 22, a driving shaft 23, a breaking blade group, a crushing blade group, and a bracket 28. The first end of the crushing cylinder 21 is closed and the second end is open. The bracket 28 is installed at the second end of the crushing cylinder 21. The driving motor 22 is arranged outside the first end of the crushing cylinder 21. The output end of the driving motor 22 is power-connected to the first end of the driving shaft 23. The driving shaft 23 passes through the first end of the crushing cylinder 21 and is arranged at the center of the crushing cylinder 21. The second end of the driving shaft 23 is rotatably connected to the bracket 28. The driving motor 22 can drive the driving shaft 23 to rotate in the crushing cylinder 21. The breaking blade group is arranged at the middle part of the driving shaft 23, and the crushing blade group is arranged close to the second end of the driving shaft 23.

[0042] Specifically, the breaking blade group includes a first breaking blade group 251, a second breaking blade group 252 and a third breaking blade group 253, the first breaking blade group 251, the second breaking blade group 252 and the third breaking blade group 253 each have at least three blades, and the free end of each blade in the first breaking blade group 251, the second breaking blade group 252 and the third breaking blade group 253 is adjacent to the inner wall of the rotating cylinder; the projection of each blade in the first breaking blade group 251, the second breaking blade group 252 and the third breaking blade group 253 on the axis of the rotating cylinder is staggered; the root of each blade in the first breaking blade group 251, the second breaking blade group 252 and the third breaking blade group 253 is connected with the driving shaft 23, the end of the blade in the first breaking blade group 251 is bent towards the first end of the rotating cylinder; the blade in the second breaking blade group 252 is inclined towards the first end of the rotating cylinder; the end of the blade in the third breaking blade group 253 is bent towards the second end of the rotating cylinder, and the blades in the first breaking blade group 251, the second breaking blade group 252 and the third breaking blade group 253 can form a turnover when the rod-shaped crops are initially broken.

[0043] In this embodiment, the driving motor 22 can drive the driving shaft 23 to rotate, and the rotation of the driving shaft 23 and the first breaking blade group 251, the second breaking blade group 252 and the third breaking blade group 253 on the driving shaft 23 can achieve the initial breaking of the rod-shaped crops. The inner wall of the rotating cylinder is also provided with a guide convex ring 254, which is arranged between the breaking blade group and the first end of the rotating cylinder and close to the breaking blade group. The guide convex ring 254 is used to guide the rod-shaped crops into the effective breaking range of the breaking blade group.

[0044] When the rod-shaped crops enter the guide convex ring 254, the rod-shaped crops are guided by the guide convex ring 254 into the breaking range of the first breaking blade group 251. After the rod-shaped crops pass through the guide convex ring 254, due to the reasons of fluid mechanics, the rod-shaped crops are more easily guided to the front bending section of the first breaking blade group 251, the rotation speed of the front bending section 291 of the first breaking blade group 251 is faster, and at the same time, the front bending section of the first breaking blade group 251 is formed at a certain angle with the axis of the crushing cylinder 21 due to its bending direction, so that the rod-shaped crops form a rapid turnover with the center of rotation being non-axial of the crushing cylinder 21 in the breaking process. When the subsequent rod-shaped crops pass through the second breaking blade group 252 and the third breaking blade group 253, the second breaking blade group 252 and the third breaking blade group 253 have a better chopping effect on the rod-shaped crops. In this embodiment, the second breaking blade group 252 is a general breaking blade. Similar to the first breaking blade group 251, when the subsequent rod-shaped crops pass through the third breaking blade group 253, the rod-shaped crops are broken again. The above-mentioned first breaking blade group 251, second breaking blade group 252 and third breaking blade group 253 have a very prominent effect on crushing the rod-shaped crops.

[0045] The first breaking knife group 251, the second breaking knife group 252 and the third breaking knife group 253 can crush the long rod-shaped crops into short segments, partially tear the rod-shaped crops, facilitate the cooperation of the rotating crushing knives 26 and the fixed crushing knives 27 to crush the rod-shaped crops, and make the rod-shaped crops more easily enter the effective crushing area of the rotating crushing knives 26 and the fixed crushing knives 27.

[0046] As preferred, the free ends of the second breaking knife group 252 and the third breaking knife group 253 form a gap with the inner wall of the crushing cylinder 21, to avoid the rod-shaped crops missing from the gap, the inner wall of the rotating cylinder is further provided with two groups of anti-leakage convex rings 255, which are respectively arranged between the first breaking knife group 251 and the second breaking knife group 252, and between the second breaking knife group 252 and the third breaking knife group 253, and the anti-leakage convex rings 255 are used to prevent the rod-shaped crops from leaking from the gap between the free ends of the breaking knife groups and the inner wall of the rotating cylinder.

[0047] The crushing knife group includes two fixed crushing knives 27 and two rotating crushing knives 26, the outer ring end of the fixed crushing knife 27 is fixedly connected with the inner wall of the crushing cylinder 21, the middle part of the fixed crushing knife 27 is rotationally connected with the driving shaft 23, the root of the rotating crushing knife 26 is connected with the driving shaft 23, and the two fixed crushing knives 27 and the two rotating crushing knives 26 are alternately arranged in the rotating cylinder, the relative blades of the fixed crushing knife 27 and the rotating crushing knife 26 are the action surface for crushing the rod-shaped crops, and the fixed crushing knife 27 and the rotating crushing knife 26 crush the rod-shaped crops through the relative shearing force.

[0048] As preferred, the fixed crushing knife 27 and the rotating crushing knife 26 are inclined from the side close to the driving shaft 23 to the side away from the driving shaft 23 to the direction of the second end of the rotating cylinder, to guide the rod-shaped crops to the outer ring direction of the fixed crushing knife 27 and the rotating crushing knife 26. The rotating speed of the outer ring direction of the fixed crushing knife 27 and the rotating crushing knife 26 is fast, the efficiency of crushing the rod-shaped crops is higher, and the rod-shaped crops are more easily enter the effective crushing area of the crushing knives and the rotating crushing knife 26.

[0049] In order to improve the crushing effect and efficiency of the crushing device, the following optimizations are made. 1. The rotating cylinder is inclined, and the first end of the rotating cylinder is lower than the second end, which can realize the separation of part of the sundries. 2. The driving shaft 23 is also provided with a fan blade 24 for driving the gas in the rotating cylinder to flow from the first end of the rotating cylinder to the second end of the rotating cylinder, further accelerating the flow of gas in the rotating cylinder. 3. When the rotating cylinder is inclined, the driving shaft 23 is also provided with an anti-sinking stirring rod 29, the root of the anti-sinking stirring rod 29 is connected with the driving shaft 23, the front end of the main body of the anti-sinking stirring rod 29 extends to the angle between the annular wall of the rotating cylinder and the first end surface of the rotating cylinder, and the front end of the anti-sinking stirring rod 29 is bent to form a bending section 291 in the circumferential direction of the rotating cylinder. The anti-sinking stirring rod 29 is used to stir the rod-shaped crops that sink into the angle between the annular wall of the rotating cylinder and the first end surface of the rotating cylinder and guide them to the effective interval of air flow. When part of the rod-shaped crops falls into the angle between the annular wall of the rotating cylinder and the first end surface of the rotating cylinder, the anti-sinking stirring rod 29 and the bending section 291 can stir the rod-shaped crops at this position, and the gas flowing from the annular wall of the rotating cylinder close to the first end will suck the rod-shaped crops sinking at this position into the smashing knife group.

The lower end of the rotating shaft 88 is connected with the first end of the swing rod guide 85. The swing rod guide 85 is horizontally arranged. The swing driving assembly 82 can drive the rotating shaft 88 to rotate in the sleeve 84 and drive the swing rod guide 85 to rotate along the axis of the rotating shaft 88. The linear slider 86 is installed in the swing rod guide 85 and can linearly slide along the swing rod guide 85. The top of the linear slider 86 is located outside the top surface of the swing rod guide 85. The coiled sheet steel 87 is sleeved outside the sleeve 84 and close to the swing rod guide 85. The inner ring end of the coiled sheet steel 87 is fixedly connected with the sleeve 84. The outer ring end of the coiled sheet steel 87 is hingedly connected with the linear slider 86. The swing driving assembly 82 can drive the swing rod guide 85 to rotate and drive the coiled sheet steel 87 to be coiled or expanded through the linear slider 86, so that the outer diameter of the coiled sheet steel 87 is expanded or reduced.

[0055] When the paper pressing device 80 needs to work, the linear driving device 81 drives the swing driving assembly 82, the sleeve 84, the swing rod guide 85, the coiled sheet steel 87 and the rotating shaft 88 to simultaneously descend. The guide column 83 plays a role of guiding the swing driving assembly 82. The coiled sheet steel 87 is in a coiled state, as shown in Figure 8 The coiled sheet steel 87 is in a first state 87A. In the first state 87A, the diameter of the coiled sheet steel 87 is small. After the coiled sheet steel 87 enters the material containing cylinder 71, the lower end of the coiled sheet steel 87 and the bottom surface of the swing rod guide 85 press the packed paper at the bottom wall inside the material containing cylinder 71.

[0056] The swing driving assembly 82 rotates. At this time, the rotating shaft 88 rotates in the sleeve 84. The sleeve 84 cannot rotate, as shown in Figure 8 The rotating shaft 88 drives the swing rod guide 85 to rotate clockwise. The coiled sheet steel 87 is gradually expanded and forms a second state 87B. In this process, the outer end of the coiled sheet steel 87 has a tendency to move outward. Therefore, the linear slider 86 hingedly connected with the outer end of the coiled sheet steel 87 also moves outward in the swing rod guide 85.

[0057] When the linear slider 86 moves to the end of the swing rod guide 85, the distance between the linear slider 86 and the lower end of the rotating shaft 88 does not change. However, the outer diameter of the coiled sheet steel 87 continues to expand after the rotating shaft 88 is slightly rotated, as shown in Figure 8In the third state 87C, the outer diameter of the rolled sheet steel strip 87 is cylindrical, which can squeeze and adhere the packaging paper to the inner ring wall of the material container 71.

[0058] Then, the rotating shaft 88 is rotated counterclockwise, and the rolled sheet steel strip 87 is retracted back to the first state 87A. The linear drive device 81 then drives the rolled sheet steel strip 87 to exit from the packing paper and the material container 71, completing the laying of the packing paper and facilitating the subsequent feeding and compaction processes. During the above process, even if there are some wrinkles in the packing paper, it will not affect the subsequent feeding and compaction processes.

[0059] This crushing device is also equipped with a baling and pressing component, in which the paper pressing device 80 can press the baling paper into the material cylinder. The outer diameter of the rolled sheet steel strip 87 can be adjusted by rotating the outer end of the rolled sheet steel strip 87. This can press the baling paper into the material cylinder, and can also completely roll and attach the baling paper to the inner wall of the material cylinder. The structure is ingenious, the cost is low, and it also has the advantages of being maintenance-free and highly efficient.

[0060] The above content is only a preferred embodiment of the present invention. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of this patent.
