Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of straw pulverizers, in particular to a mobile chrysanthemum straw pulverizer. BACKGROUND

[0002] Chrysanthemum straw is rich in organic matter, which can effectively improve soil fertility, increase soil microbial activity, promote the formation of soil aggregate structure, and thus improve soil structure and enhance soil water and fertilizer retention capacity. It can reduce the use of chemical fertilizers and achieve green circular agriculture. Therefore, after the chrysanthemum flowers are harvested, the chrysanthemum straw usually needs to be harvested and pulverized for field application. The traditional chrysanthemum straw processing method requires manual pulling of the straw, then transporting it to a specific pulverizing site for pulverization, and then transporting it back for filling. This processing method is relatively complex. In order to improve work efficiency, semi-automatic harvesters have been introduced to the market. The operator only needs to push the harvester to pass through the straw, and the internal cutter will automatically pulverize the straw. The pulverized straw falls directly to the ground for field application, which has the advantages of saving labor and being fast. However, during the harvesting process, due to the bushy characteristics and high toughness of chrysanthemum straw, it will bend along with the cutter before being cut off, and thus it is easy to be entangled on the main shaft of the pulverizer. The straw entangled on the main shaft cannot be pulverized by the cutter, and at the same time, it affects the normal operation of the machine structure, resulting in poor pulverization effect.

[0003] In view of this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solutions of the present application and does not represent the acknowledgement of the above content as the closest prior art. SUMMARY

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the application will be described clearly and completely below in conjunction with the embodiments of the application.

Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the application.

[0036] As Figures 1-13 shown in the figure is a mobile type chrysanthemum straw crusher, which comprises a vehicle body 1, a crushing box 11 arranged at the front end of the vehicle body 1, and a driving motor 12 arranged at the upper end of the crushing box 11. The crushing box 11 is internally rotatably provided with a cutter 13. The driving motor 12 drives the cutter 13 to rotate through a transmission belt 14. The cutter 13 comprises a cutter shaft 2, a plurality of groups of cutter blades 21 arranged equidistantly along the circumferential direction and the axial direction of the cutter shaft 2, and a plurality of groups of anti-winding rollers 22 rotatably arranged on the cutter shaft 2. The anti-winding rollers 22 are equidistantly distributed at intervals along the circumferential direction of the cutter blades 21. The side end of the cutter 13 is provided with a transmission assembly, so that the cutter shaft 2 drives the anti-winding rollers 22 to synchronously and reversely rotate when the cutter shaft 2 rotates. The device is manually pushed to move when in use. The cutter 13 is driven to rotate by the driving motor 12 during the movement, so that the straw entering the crushing box 11 is hit, cut and crushed by the cutter 13. In this process, part of the straw will be bent and wound around the cutter shaft 2 above the cutter 13. At this time, the anti-winding rollers 22 are arranged to reversely rotate during the rotation of the cutter shaft 2, so that when the straw is wound around the cutter shaft 2, the anti-winding rollers 22 will exert a reverse centrifugal force on the straw to make it be bounced back to normal, and then continue to be crushed by the cutter blades 21 on the cutter 13, thereby ensuring the stability of the crushing work.

[0037] In an embodiment, the pulverizing box 11 is provided with a circular side hole 3 on both sides, the transmission assembly includes a gear ring 31 arranged on the inner wall of the circular side hole 3 and a first gear 32 coaxially rotating with the anti-winding roller 22 and meshing with the gear ring 31, when the knife shaft 2 is driven, the anti-winding roller 22 is synchronously rotated, in the process of following rotation of the anti-winding roller 22, the first gear 32 arranged at both ends thereof rotates reversely under the action of meshing with the gear ring 31, thereby driving the anti-winding roller 22 to rotate in the opposite direction of the knife shaft 2.

[0038] In an embodiment, the anti-winding roller 22 includes a secondary shaft 4 and blades 41 arranged on the circumferential side of the secondary shaft 4 and gradually extending outward in the opposite rotation direction of the anti-winding roller 22, the knife shaft 2 is provided with a bearing bracket 7 rotationally connected with the secondary shaft 4 on the anti-winding roller 22, the part of the blade 41 extending away from the center of the secondary shaft 4 gradually increases, thereby having higher centrifugal force, so that the straw is more easily bounced off and thrown out.

[0039] In an embodiment, the knife blade 21 includes a straight knife 5 and a folding knife 51 arranged on both sides of the straight knife 5, the folding knife 51 has a plurality of bending points, the straight knife 5 is used to cut the staggered part of the straw, and the folding knife 51 increases the transverse cutting point position by bending, thereby being capable of cutting the straw from multiple points, improving the pulverizing efficiency.

[0040] In an embodiment, the pulverizing box 11 is provided with an air guide cover 6 on the upper side of the front end, the air guide cover 6 has a plurality of air inlets 61 towards the cutter 13 side, the air guide cover 6 is communicated with an air guide fan 62 away from the air inlet 61, the air guide fan 62 is communicated with a residue storage box 63 for storing the residue away from the air inlet 61 side, in the process of rotating and cutting the straw by the cutter 13, the air guide fan 62 is synchronously started, thereby using the air guide cover 6 to generate suction in the pulverizing box 11, so that the fine residue generated in the process of pulverizing the straw can be absorbed, avoiding the influence on the working environment and the field of vision caused by the free diffusion of the fine residue in the air, at the same time, the suction generated by the air guide cover 6 can attract the straw entering the inside of the pulverizing box 11, thereby hindering the bending of the straw, further improving the unwinding effect.
