Description

Technical Field

[0001] The invention belongs to the technical field of green agriculture and forestry, and in particular relates to a shearing device for removing branches and leaves. Background Art

[0002] Pruning branches and leaves is an important part of gardening and plant care. Reasonable pruning helps plants grow healthily, improves their morphology, and promotes flowering and fruiting. Among them, clearing and shearing of branches and leaves is particularly important. After pruning, the branches and leaves will be scattered on the ground at will, requiring a lot of manpower to pick up, and the efficiency of clearing and shearing cannot be significantly improved.

[0003] In the prior art, there is a device for pruning tomato branches and leaves and a pruning method thereof with application number: 201911018200.9, which includes a disc, a clamping mechanism, a shearing mechanism and a housing. The device uses a DC motor to simultaneously drive the clamping and pruning mechanisms to complete the work; the clamping mechanism drives two counter-rotating gears to rotate through a motor, thereby driving the clamping claws to rotate in the opposite direction to clamp the branches and leaves. At the same time, the blade rotates along two arc-shaped tracks on the fixed disc to achieve shearing.

[0004] In the above, the shearing effect of branches and leaves is basically achieved through the reverse movement of the clamp and the rotary cutting of the blade, which improves the problem of branches and leaves shaking during shearing to a certain extent. However, after reading the technical solution, it is learned that the shearing surface of the blade is a concentric circle orbit. Since most branches and stems are distributed in a ring shape with the center of the root as the axis, this circular shearing surface will cause excessive force on the connection between the branches and leaves and the roots, which may cause excessive tearing of the root texture and fail to meet the basic requirements of green agriculture and forestry. For this reason, it is necessary to change the direction of the shearing surface to maximize the protection of the root texture. Summary of the invention

[0005] The object of the present invention is to provide a shearing device for removing branches and leaves, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A shearing device for clearing branches and leaves, comprising a frame mechanism, the frame mechanism comprising a base plate, the base plate being matched with a pruning mechanism and a collecting mechanism, the pruning mechanism comprising an insertion shaft and a driving gear, one end of the driving gear being adapted and installed with the insertion shaft, the teeth of the driving gear being meshed with a driven gear, an adapter rod being installed on the side of the driven gear, a ratchet ring being sleeved on the outer surface of the adapter rod close to one side, the teeth of the ratchet ring being meshed with a toothed plate, a pruning plate being adapted and installed on the end face of the toothed plate, and a positioning cylinder being placed on the lower side of the pruning plate.

[0008] As a preferred solution of the present invention, a locking plate is mounted on the inner side of the positioning cylinder, a through pipe is provided through the center of the locking plate, and a side of the through pipe is connected to a vacuum machine.

[0009] As a preferred solution of the present invention, the number of the driven gear, the adapter rod and the ratchet ring is two groups, and the two groups of the driven gear, the adapter rod and the ratchet ring are distributed in a symmetrical arrangement.

[0010] As a preferred solution of the present invention, the bottom of the tooth plate is slidably matched with a groove, the lower surface of the groove is connected with a square frame, and one side of the tooth plate is abutted with a spring tube through an extension rod.

[0011] As a preferred solution of the present invention, the trimming plate is composed of a plurality of angle teeth of different sizes, and the sharp parts of the angle teeth are polished.

[0012] As a preferred solution of the present invention, a right-angle base is sleeved on the outer surface of the plug shaft, the bottom of the right-angle base is fixedly connected to the bottom plate, and a drive motor is adapted to be installed on the end surface of the plug shaft.

[0013] As a preferred solution of the present invention, the side of the through pipe is equipped with a string flow component, and the string flow component includes a string flow bend fixedly connected to the top of the positioning plate, and the side of the string flow bend is provided with a string flow port.

[0014] As a preferred solution of the present invention, the surface of the positioning plate is provided with side through holes, and the bottom of the through pipe is connected to a collecting cylinder.

[0015] As a preferred solution of the present invention, a collecting cylinder is adapted to be installed on the lower surface of the bottom plate, a roller is installed on the bottom of the collecting cylinder, and a handle is fixedly installed on the side of the bottom plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) through the cooperation of the frame mechanism with the pruning mechanism and the collecting mechanism, the branches and leaves can be stably sheared, and the transmission cooperation of the active gear with the driven gear and the plug shaft can allow the ratchet ring to rotate continuously, and then the tooth plate can be displaced through the form of meshing transmission. Since there is intermittent meshing between the ratchet ring and the tooth plate, the displacement of the pruning plate also satisfies intermittent motion. The displacement amplitude of the pruning plate can be flexibly adjusted according to the specific growth conditions of the branches and leaves to avoid excessive damage to the root connection of the plant when the branches and leaves are sheared. Finally, the setting of the positioning cylinder allows the sheared branches and leaves to fall directly, saving the time for picking up the branches and leaves and indirectly improving the efficiency of the next branch and leaf pruning.

[0017] (2) The symmetrical distribution of the two sets of driven gears, the adapter rod and the ratchet ring significantly improves the pruning efficiency of the pruning board. At the same time, the meshing transmission of the driven gears makes the linear displacement speed of the pruning board more stable and the pruning surface of the branches and leaves smoother, which will prevent the shearing surface of the branches and leaves from accidentally cutting people, thereby indirectly improving the safety of people when shearing branches and leaves.

[0018] (3) The pruning plate is composed of multiple angle teeth, so that the surface of the branches and leaves are repeatedly cut and pruned by the angle teeth, which is conducive to the rapid processing of the branches and leaves, saves time, and reflects the basic requirements of green agriculture.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Reference Figure 1-3 , is the first embodiment of the present invention, which provides a shearing device for removing branches and leaves, including a frame mechanism 100, wherein the frame mechanism 100 includes a base plate 101, wherein the base plate 101 is equipped with a trimming mechanism 200 and a collecting mechanism 300, wherein the trimming mechanism 200 includes an insertion shaft 203 and a driving gear 204, wherein one end of the driving gear 204 is adapted and installed with the insertion shaft 203, wherein the teeth of the driving gear 204 are meshed with a driven gear 205, wherein an adapter rod 206 is installed on the side of the driven gear 205, wherein a ratchet ring 207 is sleeved on the outer surface of the adapter rod 206 close to one side, wherein the teeth of the ratchet ring 207 are meshed with a tooth plate 208, wherein a trimming plate 212 is adapted and installed on the end surface of the tooth plate 208, wherein a positioning cylinder 301 is placed on the lower side of the trimming plate 212.

[0031] Specifically, through the cooperation of the frame mechanism 100 with the trimming mechanism 200 and the collecting mechanism 300, the branches and leaves can be stably sheared, and the transmission cooperation of the active gear 204 with the driven gear 205 and the plug shaft 203 can allow the ratchet ring 207 to rotate continuously, and then the tooth plate 208 can be driven by meshing to displace the trimming plate 212. Since there is intermittent meshing between the ratchet ring 207 and the tooth plate 208, the displacement of the trimming plate 212 also satisfies intermittent motion. The displacement amplitude of the trimming plate 212 can be flexibly adjusted according to the specific growth conditions of the branches and leaves to avoid excessive damage to the root connection of the plant when the branches and leaves are sheared. Finally, the setting of the positioning cylinder 301 allows the sheared branches and leaves to fall directly, saving the time for picking up the branches and leaves and indirectly improving the efficiency of the next branch and leaf pruning.

[0032] Furthermore, a locking plate 305 is mounted on the inner side of the positioning cylinder 301 , a through pipe 302 is provided through the center of the locking plate 305 , and a side of the through pipe 302 is connected to a vacuum machine 304 .

[0033] Preferably, by setting up the vacuum machine 304 and the through pipe 302, the inner cavity of the positioning tube 301 is evacuated and negative pressure is generated, so that the pruned branches and leaves can be directly collected. The device integrates cutting, picking and recycling, which reflects the good practicality of the device.

[0034] It should be noted that the number of the driven gear 205 , the adapter rod 206 and the ratchet ring 207 is two groups, and the distribution of the two groups of the driven gear 205 , the adapter rod 206 and the ratchet ring 207 is symmetrically arranged.

[0035] Afterwards, the symmetrical distribution of the two sets of driven gears 205, the adapter rod 206 and the ratchet ring 207 significantly improves the pruning efficiency of the pruning plate 212. At the same time, the meshing transmission of the driven gear 205 makes the linear displacement speed of the pruning plate 212 more stable through the transmission method, and the pruning surface of the branches and leaves is smoother, so that the shearing surface of the branches and leaves will not accidentally cut people, thereby indirectly improving the safety of people when shearing branches and leaves.

[0036] Reference Figure 2-5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides relevant parts for realizing the reciprocating shearing effect of the trimming plate 212.

[0037] Specifically, a groove 209 is slidably fitted at the bottom of the tooth plate 208 , a frame 211 is connected to the lower surface of the groove 209 , and a spring tube 210 is abutted against one side of the tooth plate 208 via an extension rod.

[0038] Furthermore, by connecting the groove 209 with the square frame 211, directional guidance can be provided for the linear displacement of the tooth plate 208, so that the trimming plate 212 can achieve the effect of linear trimming. At the same time, the tooth plate 208 and the spring tube 210 are in close cooperation, so that after the tooth plate 208 is pushed away by the elastic force of the spring tube 210, the trimming plate 212 can contact the branches and leaves again, so that the branches and leaves are repeatedly sheared, which also facilitates the subsequent collection of the branches and leaves.

[0039] Preferably, the trimming plate 212 is composed of a plurality of angle teeth of different sizes, and the sharp parts of the angle teeth are polished.

[0040] Among them, the trimming plate 212 is composed of multiple angle teeth, so that the surface of the branches and leaves are repeatedly cut and trimmed by the angle teeth, which is conducive to the rapid processing of the branches and leaves, saves time, and reflects the basic requirements of green agriculture.

[0041] After the above, the outer surface of the plug shaft 203 is sleeved with a right-angle base 202 , the bottom of the right-angle base 202 is fixedly connected to the bottom plate 101 , and the end surface of the plug shaft 203 is adapted to be installed with a drive motor 201 .

[0042] Appropriately, by sleeve connection between the right-angle base 202 and the plug shaft 203, the plug shaft 203 maintains its own stability during rotation, and the drive motor 201 is installed on the end face of the plug shaft 203, so that the plug shaft 203 can rotate continuously, thereby creating basic conditions for the cyclic shearing of branches and leaves.

[0043] Reference Figure 3-6 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides relevant parts for realizing the negative pressure absorption effect of the through pipe 302.

[0044] Specifically, a flow string component 303 is provided on the side of the through pipe 302 . The flow string component 303 includes a flow string bend 3032 fixedly connected to the top of the positioning plate 305 . A flow string port 3031 is provided on the side of the flow string bend 3032 .

[0045] Furthermore, through the cooperation between the string flow component 303 and the through pipe 302, the space on the upper side of the positioning plate 305 is divided into areas by the string flow component 303, and a vacuum is drawn to generate negative pressure, which facilitates the falling and collection of the branches and leaves after cutting. The setting of the string flow port 3031 and the string flow bend 3032 can allow the negative pressure string flow to reversely suck, thereby increasing the falling speed of the branches and leaves, and also meeting the specific requirements of "alternating circulation" in green agriculture.

[0046] Preferably, the surface of the positioning plate 305 is provided with a side through hole 306 , and the bottom of the through pipe 302 is connected to a collecting cylinder 307 .

[0047] Among them, by connecting the collecting tube 307 with the through pipe 302, the branches and leaves can be sucked and collected all the time, and by opening the side holes 306 on the surface of the positioning plate 305, the problem of excessive negative pressure can be prevented, thereby ensuring the stable falling of the branches and leaves.

[0048] In addition, a collecting cylinder 103 is adapted to be installed on the lower surface of the bottom plate 101 , a roller 104 is installed on the bottom of the collecting cylinder 103 , and a handle 102 is fixedly installed on the side of the bottom plate 101 .

[0049] In summary, by installing the collecting tube 103 on the bottom plate 101, the outer wall surface of the positioning tube 301 can be protected, so that more branches and leaves can be collected, which reflects the practical characteristics of the device.

[0050] Working principle: First, the whole device is guided to the branch and leaf area by the roller 104, and then the handle 102 is pulled to stabilize the device, and the first step of fixing is completed;

[0051] Then turn on the driving motor 201, the plug shaft 203 drives the driving gear 204 to rotate, and the symmetrically arranged driven gear 205 engages and transmits, and then the adapter rod 206 and the ratchet ring 207 set with the driven gear 205 rotate synchronously, and then the tooth plate 208 and the groove 209 are driven to slide relative to each other through the tooth engagement, and then the trimming plate 212 on the end face of the tooth plate 208 is displaced accordingly, and after contacting with the branches and leaves, it is close to shearing to achieve contact shearing of the branches and leaves. When the ratchet ring 207 rotates forward and reversely, one end of the tooth plate 208 contacts the spring tube 210 and causes the deformation of the built-in spring of the spring tube 210, so that the tooth plate 208 is pushed out by the elastic force. Finally, in this process, the tooth plate 208 realizes reciprocating motion, and the trimming plate 212 can also repeatedly shear the branches and leaves;

[0052] After the branches and leaves are cut, the vacuum machine 304 is started at the same time. Under the coordinated action of the series flow port 3031 and the series flow bend 3032, the negative pressure in the inner cavity of the collection tube 307 is rapidly reduced, which facilitates the rapid picking and collection of the cut branches and leaves.
