Description

Technical Field

[0001] The invention belongs to the technical field of weeding between Chinese medicinal materials, and in particular relates to a weeding and sorting device for Chinese medicinal materials under forests. Background Art

[0002] Planting Chinese herbal medicine under the forest is a model that makes full use of forest resources and develops Chinese herbal medicine planting. It has obvious advantages: the land under the forest is fertile, there are few pests and diseases, and the Chinese herbal medicines grown are of high quality. At the same time, planting under the forest can alleviate the land problem of Chinese herbal medicine planting, improve production efficiency, and conform to the new agricultural development model of sustainable development.

[0003] However, weeding of Chinese herbal medicines between plants is a major pain point in the entire planting process. The traditional way to sort weeds is to use a weeder, which consists of a gasoline engine, a transmission rod and a mowing disc. The mowing disc is driven by the transmission system to rotate at high speed, and a special polymer wire is used to generate cutting force to cut off the weeds to achieve the purpose of weeding. The weeds after rotary tillage are then collected manually, which does not completely free the hands of the workers. The overall efficiency of weeding, sorting and collecting weeds is still low.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a weeding and dividing device for Chinese medicinal materials between plants under the forest. Two rotary tillage cutters and a dividing mechanism that can move toward or away from each other are arranged on the left and right sides of the vehicle body, wherein the vertical projection of the protective part of the dividing mechanism at least covers the sweeping range of the rotary tillage cutter rotation, so that the Chinese medicinal materials can be avoided while the weeds around the Chinese medicinal materials can be rotary tilled to achieve the function of effective weeding.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: to provide a weeding and sorting device for Chinese medicinal materials between plants under the forest, comprising a vehicle body, the bottom of which is symmetrically provided with two rotary tillage cutters that can move toward or away from each other, for rotary tilling the weeds between plants;

[0007] The distribution mechanism is arranged at the bottom of the vehicle body. The distribution mechanism includes at least two symmetrically arranged protective parts, which are respectively arranged above the rotary tillage tool and move synchronously toward or away from the rotary tillage tool. The positive projection of the protective part along the vertical direction at least covers the sweeping range of the rotary tillage tool.

[0008] Furthermore, the cross-section of the protective part in the horizontal direction is in the shape of an arc, the minimum radius of the protective part is greater than or equal to the rotation radius of the rotary tillage tool, and the outer arc surfaces of the two protective parts are arranged opposite to each other.

[0009] Furthermore, two vertically arranged brackets are symmetrically arranged at the bottom of the vehicle body, and the two brackets are respectively connected with a mounting plate through a telescopic assembly that can reciprocate horizontally;

[0010] The rotary tillage cutter is rotatably connected to the mounting plate, and the protective part is fixedly connected to the mounting plate.

[0011] Furthermore, the distribution mechanism also includes:

[0012] The distribution component can be movably arranged on the rear side of the rotary tillage tool toward or away from each other. The distribution component at least comprises a vertically arranged distribution rod for distributing the weeds after the rotary tillage tool is rotary tilled to one side between the plants.

[0013] Furthermore, the distribution component also includes:

[0014] A first connecting rod is arranged on the mounting plate through a telescopic assembly capable of horizontal reciprocating movement, and the first connecting rod extends from a side of the mounting plate that is rearward and away from the rotary tillage cutter;

[0015] A plurality of second connecting rods are arranged at intervals on the first connecting rod along the extension direction of the first connecting rod. The second connecting rods extend from the side wall of the first connecting rod to the middle. The dispatching rod is arranged at the extension end of the second connecting rod.

[0016] Furthermore, the dispatch lever is rotatably connected to the extended end of the second connecting rod via a rotating shaft, and a one-way component is arranged between the dispatch lever and the second connecting rod to ensure that the two corresponding dispatch levers can only rotate in a direction away from each other.

[0017] Further, the one-way component comprises,

[0018] A rack, which is horizontally slidably disposed on the second connecting rod;

[0019] A limit block is arranged on the second connecting rod. In the initial stage, the end of the rack away from the middle position of the vehicle body abuts against the limit block;

[0020] The gear is fixedly sleeved on the rotating shaft of the dispatching lever, and the gear is meshed with the rack for transmission.

[0021] Furthermore, the one-way component also includes,

[0022] A slide bar is horizontally arranged on the second connecting rod, and the rack is slidably arranged relative to the slide bar;

[0023] The reset spring is sleeved on the slide rod and is used for resetting the sliding of the rack.

[0024] Furthermore, a driving motor is provided on the mounting plate, and a driving end of the driving motor is fixedly connected to the rotating end of the rotary tillage cutter;

[0025] A cam is arranged on the rotating end of the rotary tillage tool, and the maximum rotation radius of the cam is at least greater than the vertical distance from the center of the rotating end of the rotary tillage tool to the first connecting rod.

[0026] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0027] (1) The present invention arranges two rotary tillage cutters and a distribution mechanism that can move toward or away from each other on the left and right sides of the vehicle body, wherein the vertical projection of the protective portion of the distribution mechanism at least covers the sweeping range of the rotary tillage cutter, thereby avoiding the Chinese medicinal materials while rotary tilling the weeds around the Chinese medicinal materials, thereby achieving the function of effective weed removal.

[0028] (2) The present invention can effectively limit the arc length of the protective part by limiting the minimum radius of the protective part to be greater than or equal to the rotation radius of the rotary tillage tool and the tangent at the end is perpendicular to the forward direction of the vehicle body. During the rotation of the rotary tillage tool, the protective part can effectively ensure that the rotary tillage tool can separate the surrounding weeds when the relative outer walls of the two protective parts hit the Chinese herbal medicines between plants while rotary tilling the weeds, thereby preventing the rotary tillage tool from damaging the Chinese herbal medicines during the weeding process.

[0029] (3) The present invention connects the distribution rod on the mounting plate through a telescopic assembly that can move horizontally back and forth, ensuring that while the mounting plate drives the first connecting rod to move, the first connecting rod itself has the freedom to move toward or away from each other, thereby ensuring that the weeds after rotary tillage can be stacked in an orderly manner, facilitating subsequent centralized collection.

[0030] (4) The distribution lever of the present invention is rotatably connected to the extended end of the second connecting rod through a rotating shaft, and a one-way component is provided between the two. Therefore, when the distribution lever is squeezed by the weeds after rotary tillage, it will not rotate, and the weeds after rotary tillage can be effectively distributed. When the rotary tillage cutter approaches the middle and the distribution lever also moves toward the middle of the vehicle body, and the distribution lever is squeezed by the weeds at this time, the gear will engage the rack and rotate, and the rack can slide relative to the mounting plate, so there is no locking effect, so that the distribution lever can be rotated, and the weeds will not be pushed toward the middle when the distribution lever approaches the middle.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] like Figures 1 to 7 As shown, the device for weeding and sorting between plants of Chinese medicinal materials under forests of the present invention comprises a vehicle body 1, the bottom of which is symmetrically provided with two rotary tillage cutters 2 that can move toward or away from each other, and is used for rotary tilling the weeds between plants;

[0046] The distribution mechanism 3 is arranged at the bottom of the vehicle body 1. The distribution mechanism 3 includes at least two symmetrically arranged protective parts 31, which are respectively arranged above the rotary tillage tool 2 and move toward or away from each other synchronously with the rotary tillage tool 2. The positive projection of the protective part 31 along the vertical direction at least covers the sweeping range of the rotary tillage tool 2.

[0047] In the present invention, the vehicle body 1 has a frame, and two rotary tillage tools 2 are arranged at the bottom of the frame. The forward direction of the vehicle body 1 is taken as the X-axis, and the vertical direction perpendicular to the vehicle body 1 is taken as the Z-axis. The two rotary tillage tools 2 are arranged symmetrically about the X-axis of the vehicle body 1, and the weeds in the moving process are rotary tilled by the two rotary tillage tools 2.

[0048] A distribution mechanism 3 is arranged above the rotary tillage cutter 2 and is parallel to the rotary tillage cutter 2. Two protection parts 31 are arranged on one side of the corresponding rotary tillage cutter 2. The two protection parts 31 are also arranged symmetrically about the X axis of the vehicle body 1. The positive projection of the protection part 31 in the direction of the Z axis can completely cover the area swept by the radius of rotation of the rotary tillage cutter 2. When the vehicle body 1 moves forward, the protection part 31 touches the Chinese medicinal materials, causing the rotary tillage cutter 2 to move to both sides (directions away from each other), so that the Chinese medicinal materials can be avoided while the weeds around the Chinese medicinal materials can be rotary tilled to achieve the function of effective weeding.

[0049] In addition, the vehicle body 1 of the entire device can be driven electrically or manually to move forward among the trees under the forest.

[0050] Furthermore, the cross section of the protection part 31 in the horizontal direction is in the shape of an arc, the minimum radius of the protection part 31 is greater than or equal to the rotation radius of the rotary tiller tool 2, and the outer arc surfaces of the two protection parts 31 are arranged opposite to each other.

[0051] In the present invention, the protective part 31 is in the shape of a circular arc rod, and the two protective parts 31 are horizontally arranged symmetrically about the X-axis. The tangent at the end of the protective part 31 is perpendicular to the X-axis of the vehicle body 1, so that the arc length of the protective part 31 can be effectively limited. During the rotation of the rotary tillage tool 2, the protective part 31 can effectively ensure that the rotary tillage tool 2 can separate the surrounding weeds when the relative outer side walls of the two protective parts 31 touch the Chinese herbal medicines between the plants while rotary tilling the weeds, thereby preventing the rotary tillage tool 2 from damaging the Chinese herbal medicines during the weeding process. It should be noted that the inner arc radius of the protective part 31 is not less than the rotation radius of the rotary tillage tool 2, so that the rotary sweep range of the rotary tillage tool 2 can be completely covered under the vertical projection angle, and through the coordination of the arc length of the protective part 31, it can be fully ensured that the protective part 31 separates the rotary tillage tools 2 from each other after touching the Chinese herbal medicines, thereby processing the weeds during its own rotation and cutting process.

[0052] Furthermore, two vertically arranged brackets 11 are symmetrically arranged at the bottom of the vehicle body 1, and the two brackets 11 are respectively connected to the mounting plate 4 through the telescopic components 5 that can reciprocate horizontally;

[0053] The rotary tillage cutter 2 is rotatably connected to the mounting plate 4 , and the protection portion 31 is fixedly connected to the mounting plate 4 .

[0054] In the present invention, a vertically extending bracket 11 is symmetrically arranged at the bottom of the frame of the vehicle body 1, and a through hole is symmetrically arranged on the bracket 11, and a telescopic component 5 is arranged on the through hole to connect the mounting plate 4. Specifically, the telescopic component 5 includes a T-shaped rod 51 that can slide through the through hole, and a telescopic spring 52 is sleeved on the T-shaped rod 51, and the free end of the T-shaped rod 51 is connected to the mounting plate 4. The bottom of the mounting plate 4 is provided with the rotary tillage tool 2, and the top is provided with a protective part 31, so that after the protective part 31 is squeezed by the Chinese herbal medicine, it can drive the mounting plate 4 including the rotary tillage tool 2 to move to both sides as a whole, thereby ensuring that the Chinese herbal medicine is not damaged and the weeds around the Chinese herbal medicine can be removed by rotary tillage.

[0055] Furthermore, the distribution mechanism 3 also includes:

[0056] The distribution assembly 32 is movably arranged on the rear side of the rotary tillage cutter 2 toward or away from each other. The distribution assembly 32 comprises at least a vertically arranged distribution rod 323 for distributing the weeds after the rotary tillage cutter 2 has been rotary tilled to one side between the plants.

[0057] In the present invention, the distribution assembly 32 in the distribution mechanism 3 is arranged at the rear side of the rotary tillage cutter 2 (with the direction of the vehicle body 1 moving forward as the front), wherein the distribution rods 323 in the distribution assembly 32 can be multiple and connected to the mounting plate 4. When the rotary tillage cutter 2 moves to both sides with the driving of the protection part 31, the distribution rods 323 can move to both sides with the mounting plate 4 on the one hand, and realize the outward separation and shifting action through its own movement on the other hand. After the rotary tillage cutter 2 tills the weeds, the cut weeds can be shifted in the moving direction in time through the distribution rods 323, so that the cut weeds can be uniformly shifted to both sides of the Chinese herbal medicine, thereby providing convenience for the subsequent weed collection operation.

[0058] Furthermore, the distribution assembly 32 also includes:

[0059] A first connecting rod 321 is arranged on the mounting plate 4 through a telescopic assembly 5 that can reciprocate horizontally. The first connecting rod 321 extends from a side of the mounting plate 4 that is backward and away from the rotary tillage cutter 2;

[0060] A plurality of second connecting rods 322 are disposed at intervals on the first connecting rod 321 along the extension direction of the first connecting rod 321 . The second connecting rods 322 extend from the sidewalls of the first connecting rod 321 toward the middle. The dispatching rod 323 is disposed at the extension end of the second connecting rod 322 .

[0061] In the present invention, the first connecting rod 321 is arranged on the rear side wall of the mounting plate 4 and connected by a telescopic assembly 5. The telescopic assembly 5 is completely consistent with the telescopic assembly 5 connected to the mounting plate 4, and no further details are given here. By connecting the first connecting rod 321 by the telescopic assembly 5, it can be ensured that while the mounting plate 4 drives the first connecting rod 321 to move, the first connecting rod 321 itself has the freedom to move toward or away from each other. Thus, it can be ensured that the weeds after rotary tillage can be stacked in an orderly manner, which is convenient for subsequent centralized collection.

[0062] Specifically, the first connecting rod 321 extends rearward along the direction of the vehicle body 1X axis, starting from the rear side wall of the mounting plate 4. The first mounting stem is also provided with a plurality of second connecting rods 322 which are perpendicular to the extension direction and placed horizontally. The plurality of second connecting rods 322 are arranged at equal intervals. A distribution rod 323 extending vertically downward is provided at the rod head position of each second connecting rod 322. The distribution rods 323 are arranged in a vertical row, so that the subsequent distribution rods 323 can distribute the weeds at the moment after the rotary tillage tool 2 tills the weeds.

[0063] Furthermore, the dispatching rod 323 is rotatably connected to the extended end of the second connecting rod 322 via a rotating shaft, and a one-way component 7 is provided between the dispatching rod 323 and the second connecting rod 322 to ensure that the two corresponding dispatching rods 323 can only rotate in a direction away from each other.

[0064] In the present invention, another preferred connection mode of the distribution rod 323 can be that the distribution rod 323 is connected to the rod head of the second connecting rod 322 by a rotating shaft, and a one-way component 7 that can only rotate in the direction away from each other and is locked in the opposite direction is provided between the rotating shaft of the distribution rod 323 and the second connecting rod 322. Since the rotary tillage cutters 2 move toward or away from each other accordingly as the protective part 31 is pressed, when the two rotary tillage cutters 2 move toward each other, the distribution rod 323 will also move in the direction of approaching each other. At this time, in order to prevent the weeds after rotary tillage from being moved toward the middle Chinese herbal medicine by the distribution rod 323, during the approaching process, the distribution rod 323 will be affected by the weeds and swing outward, that is, the distribution rod 323 is not locked at this time, and can be forced to swing at any time, thereby effectively ensuring that the distribution direction of the weeds is always moved in the direction away from each other, so that the weeds after rotary tillage can be orderly distributed and piled on both sides of the Chinese herbal medicine between the plants, ensuring the subsequent weed collection operation.

[0065] Further, the one-way component 7 comprises,

[0066] The rack 72 is horizontally slidably disposed on the second connecting rod 322;

[0067] The limit block 71 is arranged on the second connecting rod 322. In the initial stage, the end of the rack 72 away from the middle position of the vehicle body 1 abuts against the limit block 71;

[0068] The gear 74 is fixedly sleeved on the rotating shaft of the dispatching lever 323 , and the gear 74 is meshed with the rack 72 for transmission.

[0069] In the present invention, the specific one-way component 7 includes a rack 72, a stopper 71 and a gear 74. A mounting ear 8 is provided below the rod head of the second connecting rod 322, a rotating shaft is rotatably connected in the mounting ear 8, one end of the rotating shaft passes through the mounting ear 8 and is connected to a vertical declutching rod 323, and a gear 74 is sleeved on the outer side of the rotating shaft protruding from the mounting ear 8; the rack 72 provided on the mounting ear 8 is horizontal, and the rack 72 is meshed with the gear 74 for transmission, wherein the rack 72 can slide freely relative to the length direction of the second connecting rod 322.

[0070] The locking cam 74 is in the process of locking the locking cam 323 against the locking cam 324, so that the lock cam 323 is locked with the locking cam 324 when the locking cam 323 is in the process of locking the locking cam 323 and locking the cam 324.

[0071] Furthermore, the one-way component 7 also includes:

[0072] The slide bar 73 is horizontally arranged on the second connecting rod 322, and the rack 72 is slidably arranged relative to the slide bar 73;

[0073] The return spring 75 is sleeved on the slide bar 73 and is used for returning the sliding of the rack 72 .

[0074] In the present invention, the rack 72 in the one-way component 7 is installed by being horizontally fixed on the slide bar 73 on the side wall of the mounting ear 8 in the second connecting rod 322, wherein the slide bar 73 is spaced a certain distance from the plate surface of the mounting ear 8, and the rack 72 is provided with a sliding hole matched with the slide bar 73, and a return spring 75 is sleeved on the slide bar 73, wherein the two ends of the return spring 75 are respectively against the side wall of the slide bar 73 and the side wall of the rack 72. When the declutching rod 323 is not subjected to the extrusion force, the return spring 75 can make the declutching rod 323 always maintain a vertical state.

[0075] Furthermore, a driving motor 6 is provided on the mounting plate 4, and a driving end of the driving motor 6 is fixedly connected to the rotating end 21 of the rotary tillage tool 2;

[0076] A cam 22 is provided on the rotating end 21 of the rotary tiller 2 , and the maximum rotation radius of the cam 22 is at least greater than the vertical distance from the center of the rotating end 21 of the rotary tiller 2 to the first connecting rod 321 .

[0077] In the present invention, the driving of the rotary tillage tool 2 is realized by the driving of the driving motor 6 on the mounting plate 4. A cam 22 structure is arranged on the side wall of the rotating end 21 of the rotary tillage tool 2. The maximum turning radius of the cam 22 is greater than the vertical distance from the center of the rotating end 21 of the rotary tillage tool 2 to the first connecting rod 321. The end of the rotating end 21 of the rotary tillage tool 2 is fixedly connected to the rotary tillage tool 2. The cam 22 structure is arranged on the outer side wall of the rotating end 21. Thus, during the rotation of the driving motor 6, the rotary tillage tool 2 is rotated on the one hand, and the first connecting rod 321 can be periodically squeezed by the cam 22, so that the dividing rod 323 periodically reciprocates horizontally. This can adapt to the continuous rotation of the weeds after the rotary tillage tool 2 is rotary tilled. When the two dividing rods 323 are close to each other, the dividing operation is not performed, and when they are away from each other, the dividing operation is performed. The overall dividing operation can also be performed continuously, which improves the efficiency of the rotary tillage operation and the dividing operation.
