Description

Technical Field

[0001] The invention relates to the technical field of straw crushers, and in particular to a mobile chrysanthemum straw crusher. Background Art

[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, enhance soil water and fertilizer retention capacity, reduce the use of chemical fertilizers, and realize green circular agriculture. Therefore, after the chrysanthemum flowers are harvested, the chrysanthemum straw usually needs to be harvested, crushed and returned to the field. The traditional method of processing chrysanthemum straw requires manual pulling of the straw, and then transporting it to a specific crushing site for crushing, and then transporting it back for replacement. This processing method is relatively complicated. In order to improve work efficiency, semi-automatic harvesters are currently available on the market. The staff only needs to push the harvester to pass through the straw, and the internal cutter will automatically crush the straw. After the straw is crushed, it will fall directly to the ground and return to the field, which has the advantages of saving effort and being quick. However, during the harvesting process, due to the shrub characteristics and high toughness of the chrysanthemum straw, it will bend with the cutter before it is cut, and then it is very easy to be entangled in the main shaft of the crusher. The straw wrapped around the main shaft cannot be crushed by the cutter, and at the same time affects the normal operation of the body structure, resulting in poor crushing effect.

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

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a mobile chrysanthemum straw crusher.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A mobile chrysanthemum straw crusher comprises a vehicle body, a crushing box arranged at the front end of the vehicle body and a driving motor arranged at the upper end of the crushing box, a cutter is rotatably arranged inside the crushing box, the driving motor drives the cutter to rotate via a transmission belt, the cutter comprises a cutter shaft, a plurality of groups of blades equidistantly arranged along the circumferential direction and axial direction of the cutter shaft, and a plurality of groups of anti-entanglement rollers rotatably arranged on the cutter shaft, the anti-entanglement rollers are equidistantly distributed at intervals where the blades are arranged along the circumferential direction of the cutter shaft; a transmission assembly is arranged at the side end of the cutter so that the cutter shaft drives the anti-entanglement roller to rotate synchronously in the opposite direction when rotating.

[0008] Furthermore, circular side holes are opened on both sides of the crushing box, and the transmission assembly includes a gear ring arranged on the inner wall of the circular side hole and a first gear coaxially rotating with the anti-winding roller and meshing with the gear ring.

[0009] Furthermore, the anti-entanglement roller includes a secondary shaft and blades that are evenly distributed on the circumferential side of the secondary shaft and gradually extend outward along a rotation direction opposite to that of the anti-entanglement roller.

[0010] Furthermore, the blade includes a straight blade and folding blades arranged on both sides of the straight blade, wherein the folding blade has at least one bending point.

[0011] Furthermore, an air guide hood connected to the interior of the crushing box is provided on the upper front end thereof, wherein the air guide hood has a plurality of air suction ports facing the tool side, an end of the air guide hood away from the air suction ports is connected to an induced draft fan, and a side of the induced draft fan away from the air suction ports is connected to a slag storage box for storing crushed slag.

[0012] Furthermore, the knife shaft is provided with a bearing frame rotatably connected to the secondary shaft on the anti-winding roller.

[0013] Furthermore, the slag storage box is connected to the induced draft fan through a slag inlet, and an exhaust port is provided at a side end thereof, and a filter plate is movably provided inside, wherein the exhaust port is located on one side of the filter plate.

[0014] Furthermore, the interior of the slag storage box is divided into a driving bin and a processing bin by a partition, wherein the slag inlet is located on one side of the driving bin, and the driving bin and the processing bin are connected; one end of the filter plate is movably connected to the side wall of the processing bin and the other end is movably connected to the partition, a wind wheel is rotatably provided in the driving bin and faces the slag inlet, a second gear is provided on the wind wheel, and a third gear meshing with the second gear is rotatably provided on the side wall of the driving bin, and the third gear is connected to the filter plate through a crank connecting rod.

[0015] Furthermore, the filter plate separates the processing chamber into a filter residue area and a drainage area, wherein the filter residue area is connected to the interior of the driving chamber, and the drainage area is connected to the exhaust port.

[0016] Compared with the prior art, the beneficial effect of the present scheme is as follows: the present invention arranges blades and anti-entanglement rollers at the upper end of the cutter, and cooperates with the transmission assembly to achieve the effect of reverse rotation of the anti-entanglement roller when the cutter shaft rotates, so that when the cutter cuts straw, the straw that is bent and wrapped around the cutter shaft will be flicked away by the anti-entanglement roller, thereby avoiding the problem of straw wrapping around the cutter and affecting cutting, and improving the crushing stability.

[0017] The anti-entanglement roller is provided with blades which gradually extend outward at its upper end, so that the external centrifugal force is increased during the rotation process, thereby making it easier to push the straw away and throw it out, thereby enhancing the anti-entanglement effect.

[0018] By setting up the air guide hood, the fine debris generated in the process of crushing the straw can be absorbed to prevent the debris from flying and affecting the working environment. At the same time, the suction force of the air guide hood can help prevent the bending of the straw, making it easier to crush, further improving the crushing efficiency.

[0019] By arranging a wind wheel inside the slag storage box, the slag will drive the wind wheel to rotate when entering the inside, and then the wind wheel will drive the filter plate to reciprocate through the second gear, the third gear and the crank connecting rod, so that it maintains a continuous shaking and filtering state, thereby avoiding the situation where the slag is stuck in the filter screen and the filtering effect is reduced, and the filtering stability is ensured.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0036] like Figure 1-13 The mobile chrysanthemum straw crusher shown in the figure comprises a body 1, a crushing box 11 arranged at the front end of the body 1 and a driving motor 12 arranged at the upper end of the crushing box 11, a cutter 13 is rotatably arranged inside the crushing box 11, and the driving motor 12 drives the cutter 13 to rotate through a transmission belt 14, and the cutter 13 comprises a cutter shaft 2, a plurality of groups of blades 21 equidistantly arranged along the circumferential direction and axial direction of the cutter shaft 2, and a plurality of groups of anti-entanglement rollers 22 rotatably arranged on the cutter shaft 2, and the anti-entanglement rollers 22 are equidistantly distributed at intervals where the blades 21 are arranged along the circumferential direction of the cutter shaft 2; a transmission assembly is arranged at the side end of the cutter 13, so that the cutter shaft 2 drives the anti-entanglement rollers 22 when rotating. The roller 22 rotates in the opposite direction synchronously. When in use, the device is manually pushed forward, and during the movement, the drive motor 12 drives the cutter 13 to rotate, 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 follow the cutter 13 to bend and wrap around the cutter shaft 2 thereon. At this time, an anti-winding roller 22 is provided to make it rotate in the opposite direction during the rotation of the cutter shaft 2. Therefore, when straw is wrapped around the cutter shaft 2, the anti-winding roller 22 will apply reverse centrifugal force to the straw, causing it to be bounced back to the normal position, and then continue to be crushed by the blade 21 on the cutter 13, thereby ensuring the stability of the crushing work.

[0037] In one embodiment, circular side holes 3 are provided on both sides of the crushing box 11, and 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-entanglement roller 22 and meshing with the gear ring 31. When the cutter shaft 2 is active, it drives the anti-entanglement roller 22 to rotate synchronously. In the process of the anti-entanglement roller 22 following the rotation, the first gears 32 arranged at both ends thereof rotate in the opposite direction under the action of meshing with the gear ring 31, thereby driving the anti-entanglement roller 22 to rotate in the opposite direction to the cutter shaft 2.

[0038] In one embodiment, the anti-entanglement roller 22 includes a secondary shaft 4 and blades 41 evenly distributed on the circumferential side of the secondary shaft 4 and gradually extending outward along the rotation direction opposite to the anti-entanglement roller 22. A bearing frame 7 rotatably connected to the secondary shaft 4 on the anti-entanglement roller 22 is provided on the knife shaft 2. The extended part of the blade 41 gradually increases its distance from the center of the secondary shaft 4, thereby having a higher centrifugal force, thereby making it easier to bounce off and throw out the straw.

[0039] In one embodiment, the blade 21 includes a straight knife 5 and a folding knife 51 arranged on both sides of the straight knife 5, wherein the folding knife 51 has multiple bending points. The straight knife 5 is used to cut the staggered part of the straw, and the folding knife 51 increases the horizontal cutting points by bending, so that cutting can be implemented from multiple points of the straw, thereby improving the crushing efficiency.

[0040] In one embodiment, an air guide hood 6 connected to the interior of the pulverizing box 11 is provided on the upper side of the front end thereof, wherein the air guide hood 6 has a plurality of air suction ports 61 facing the side of the cutter 13, and an end of the air guide hood 6 away from the air suction ports 61 is connected to an induced draft fan 62, and a side of the induced draft fan 62 away from the air suction ports 61 is connected to a slag storage box 63 for storing slag. During the process of the cutter 13 rotating to cut the straw, the induced draft fan 62 is started synchronously, and then the air guide hood 6 is used to generate suction in the pulverizing box 11, so that the fine slag generated in the process of pulverizing the straw can be absorbed to prevent it from freely diffusing in the air and affecting the working environment and field of vision. At the same time, the suction generated by the air guide hood 6 can simultaneously attract the straw entering the pulverizing box 11, thereby preventing it from bending, and further improving the detangling effect.

[0041] In one embodiment, the slag storage box 63 is connected to the induced draft fan 62 through the slag inlet 8, and an exhaust port 81 is opened at its side end, and a filter plate 82 is movably arranged inside, wherein the exhaust port 81 is located on one side of the filter plate 82, and the interior of the slag storage box 63 is divided into a driving bin 91 and a processing bin 92 by a partition 9, wherein the slag inlet 8 is located on one side of the driving bin 91, and the driving bin 91 is connected to the processing bin 92; one end of the filter plate 82 is movably connected to the side wall of the processing bin 92 and the other end is movably connected to the partition 9, a wind wheel 93 facing the slag inlet 8 is rotatably arranged in the driving bin 91, a second gear 94 is arranged on the wind wheel 93, and a third gear 95 meshing with the second gear 94 is rotatably arranged on the side wall of the driving bin 91, and the third gear 95 is connected to the filter plate 82 through a crank connecting rod 96, and the filter plate 82 divides the processing bin 92 into a filter residue area 97 and a discharge area 98, wherein The middle filter residue area 97 is connected to the inside of the driving bin 91, and the discharge area 98 is connected to the exhaust port 81. When the absorbed debris enters the slag storage box 63 through the induced draft fan 62, the high-speed airflow will drive the wind wheel 93 to rotate, and the debris enters the filter residue area 97 from the driving bin 91, and then passes through the filter plate 82 for filtration, and the filtered airflow enters the discharge area 98 and is discharged from the driving bin 91. While the wind wheel 93 rotates, it will be transmitted to the third gear 95 through the second gear 94 to make it rotate synchronously, and the third gear 95 drives the filter plate 82 to perform horizontal reciprocating motion through the crank connecting rod 96. The filter plate 82 is arranged to be inclined toward the processing bin 92 side. In this way, during the high-speed shaking of the filter plate 82, the debris stuck in the filter screen is vibrated out and falls under the action of gravity, ensuring that the filter screen will not be blocked by debris during the filtration process, so that the overall collection of debris by the slag storage box 63 is more stable and efficient.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
