DETAILED DESCRIPTION

[0029] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1

[0031] See also Figures 1 to 10 The present invention provides a technical solution: comprising a pruning device protective shell 1, a pruning blade assembly 3 is arranged on the inner side of the pruning device protective shell 1, a branch grabbing limit assembly 4 is arranged below the pruning device protective shell 1, a grape branch processing assembly 5 is arranged at the bottom of the pruning device protective shell 1, the pruning blade assembly 3 comprises an eagle-beak-shaped shearing knife 34, the branch grabbing limit assembly 4 comprises a branch grabbing limit bending rod 41 arranged on the inner side of the lower side of the pruning device protective shell 1, and a movable groove adapted to the branch grabbing limit bending rod 41 is arranged on the lower side wall of the pruning device protective shell 1, the pruning blade assembly 3 also comprises a motor mounting bracket 31 fixedly mounted on the outer side wall of the pruning device protective shell 1, and the motor mounting bracket 31 The outer wall of the pruning device protective housing 1 is fixedly installed with a motor 2 32, a rotating sleeve 33 is rotatably installed in the middle of the inner wall of one side of the pruning device protective housing 1, one end of the rotating shaft of the rotating sleeve 33 passes through the pruning device protective housing 1, the side wall of the motor mounting frame 31 and is fixedly connected to the output shaft of the motor 2 32, a gear 1 331 is fixedly installed on the outer surface of the rotating shaft of the rotating sleeve 33, a clamping cutter head 35 is provided on the inner wall of the other side of the pruning device protective housing 1, and a mounting bolt 351 is rotatably installed on the outer end of the clamping cutter head 35, and the outer surface of the mounting bolt 351 is threadedly connected to the inner wall of the pruning device protective housing 1, and the outer surfaces of both sides of the hawk-beak-shaped shearing knife 34 are respectively clamped with the clamping cutter head 35 and the inner wall of the rotating sleeve 33;

[0032] In the present embodiment, the motor mounting bracket 31 mainly serves to mount the motor 2 32. It is worth noting that a battery assembly for supplying energy to the motor 2 32 is mounted on the outer side of the motor mounting bracket 31. The motor 2 32 drives the rotating shaft sleeve 33 to rotate, and the hawk-beak shearing knife 34 is mounted on the rotating shaft sleeve 33. The mounting bolt 351 is rotated to make the engaging cutter head 35 engage with the other side of the rotating shaft sleeve 33, so as to complete the fixation of the hawk-beak shearing knife 34. At the same time, it is also convenient to disassemble and replace the hawk-beak shearing knife 34 in the later stage. It only needs to reversely rotate the mounting bolt 351 to move out the engaging cutter head 35 to remove it. The hawk-beak shearing knife 34 is replaced. It is worth noting again that the tightening direction of the mounting bolt 351 is consistent with the rotation direction of the hawk-beak shearing knife 34. The special design of the motor 32 has a hooking effect on the grape branches when it rotates downward, and cooperates with the branch-grabbing limiting component 4 to facilitate one-time cutting, thereby improving pruning efficiency. It solves the problem that the prior art uses the rotation of the blade to prune the grape branches, but lacks the limiting function on the other side of the grape branches, causing the grape branches to splash and affecting the fruit farmers with the handheld pruning device. The sheared branches can be processed by adding a limiting structure on one side of the blade and cooperating with it.

[0033] Embodiment 2

[0034] See also Figures 1 to 10 On the basis of the first embodiment, in order to cooperate with the hawk-beak shearing knife 34 to rotate and prune the grape branches to limit the position, the present embodiment further proposes that two groups of branch-grabbing limiting bending rods 41 are provided, and a gap for the hawk-beak shearing knife 34 to pass through is provided in the middle of the two groups of branch-grabbing limiting bending rods 41, and a rotating shaft 411 is fixedly installed at one end of the two groups of branch-grabbing limiting bending rods 41, and the rotating shaft 411 is rotatably installed below the side wall of the pruning device protective housing 1, and a gear 2 412 is fixedly installed at one end of the rotating shaft 411 close to the motor mounting frame 31, and a driving shaft 1 42 is provided above the branch-grabbing limiting bending rod 41, and the driving shaft 1 42 is rotatably installed on the side wall of the pruning device protective housing 1, and a gear 3 421 meshing with the gear 1 331 is fixedly installed at one end of the driving shaft 1 42, and the driving shaft 1 42 is movably connected to one end of the branch-grabbing limiting bending rod 41 through a belt pulley assembly;

[0035] In this embodiment, the gear 3 421 on the driving shaft 1 42 is meshed with the gear 1 331, so that the driving shaft 1 42 is driven to keep rotating in the direction opposite to the rotating shaft sleeve 33. At the same time, the driving shaft 1 42 drives the rotating shaft 411 to rotate through the belt, so that the branch-grabbing limiting bending rod 41 also keeps rotating in the opposite direction to the hawk-beak-shaped shearing knife 34. When the hawk-beak-shaped shearing knife 34 rotates downward to cut, the branch-grabbing limiting bending rod 41 rotates upward to grasp and limit the grape branch, so that the hawk-beak-shaped shearing knife 34 is cut off when it passes between the hawk-beak-shaped shearing knives 34, avoiding the grape branch from being cut. Grape branches splash when they are cut. It is worth noting that the front end of the branch-grabbing limit bending rod 41 can be rotated and flipped outward so that it can pass through the middle of the pruning device protective shell 1 and then be thrown out by centrifugal force to ensure smooth rotation. The hawk-beak shearing knife 34 is used to prune the grape branches, which further solves the problem that the existing technology uses the rotation of the blade to prune the grape branches, but the other side lacks the limit on the grape branches, causing the grape branches to splash and affecting the fruit farmers with the handheld pruning device. The sheared branches can be processed by adding a limit structure on one side of the blade and cooperating with it.

[0036] Embodiment 3

[0037] See also Figures 1 to 10 On the basis of the second embodiment, in order to prevent the cut grape branches from affecting the fruit farmers holding the adjusting sleeve rod 22, the present embodiment further proposes that the grape branch processing assembly 5 includes a processing box 51 fixedly mounted on the lower surface of the protective housing 1 of the pruning device, and the inner wall of one side of the processing box 51 is evenly distributed with sliding strips 53, and the bottom inner wall of the processing box 51 is fixedly mounted with a guide pipe 52, and the middle inner wall of the processing box 51 is rotatably mounted with a rotating rod 54, and the outer surface of the rotating rod 54 is fixedly mounted with a cutting knife 541, and the interval of the sliding strip 53 is staggered with the interval of the cutting knife 541, and the inner wall of one side of the processing box 51 close to the motor mounting frame 31 is rotatably mounted with a driving shaft 2 55, and one end of the driving shaft 2 55 is fixedly mounted with a gear 4 551 meshing with the gear 2 412, and the driving shaft 2 55 is movably connected with one end of the rotating rod 54 through a belt pulley assembly;

[0038] In this embodiment, the processing box 51 is located below the protective shell 1 of the pruning device to receive the grape branches cut by the eagle-beak shearing knife 34. The gear 4 551 is meshed with the gear 2 412 to drive the driving shaft 2 55 to rotate, and the driving shaft 2 55 drives the rotating rod 54 to rotate through the belt, so that the cutting knife 541 performs a secondary cutting on the grape branches falling on the sliding strip 53 so that they are cut into small sections, and fall into the processing box 51 along the sliding strip 53, and then are discharged in another direction through the outlet pipe 52 to avoid affecting the fruit growers below. It is worth noting that the cutting knife 541 is bent outward. The cutting knife 541 and the sliding strip 53 are alternately arranged. When rotating, they pass through the sliding strip 53 to have a downward pressing and cutting effect on the grape branches, which further solves the problem that the existing technology uses the rotation of the blade to prune the grape branches and the other side lacks the grape branch limit, causing the grape branches to splash and affect the fruit growers with the handheld pruning device. The sheared branches can be processed by adding a limiting structure on one side of the blade and cooperating to complete the processing.

[0039] Embodiment 4

[0040] See also Figures 1 to 10 On the basis of the third embodiment, in order to achieve the height adjustment of the protective housing 1 of the pruning device, the present embodiment further proposes that the protective housing 1 of the pruning device is provided with a telescopic handle assembly 2, and the telescopic handle assembly 2 includes a telescopic rod 21 fixedly mounted on the side wall of the protective housing 1 of the pruning device by bolts, and an adjusting sleeve rod 22 is slidably mounted on the lower outer surface of the telescopic rod 21, and an adjusting threaded rod 23 is rotatably mounted on the inner middle part of the adjusting sleeve rod 22, and the bottom inner wall of the telescopic rod 21 is threadedly connected with the outer surface of the adjusting threaded rod 23, and a motor 24 for driving the adjusting threaded rod 23 to rotate is fixedly mounted at the bottom of the adjusting sleeve rod 22, and a controller is fixedly mounted on the side wall of the adjusting sleeve rod 22;

[0041] In the present embodiment, it is worth noting that the controller of the adjusting sleeve 22 is respectively connected to the motor 2 32 and the motor 1 24 through electric wires. By holding the adjusting sleeve 22 and pressing the controller, the motor 1 24 is controlled to rotate and drive the adjusting threaded rod 23 to rotate, so that the telescopic rod 21 can be adjusted in height under the limit cooperation of the adjusting sleeve 22, which is suitable for pruning grape branch racks of different heights. This further solves the problem that the existing technology uses the rotation of the blade to prune the grape branches, but the other side lacks the limit of the grape branches, causing the grape branches to splash and affect the fruit farmers with the handheld pruning device. The sheared branches can be processed by adding a limit structure on one side of the blade and cooperating with it.

[0042] Embodiment 5

[0043] See also Figures 1 to 10 Based on the fourth embodiment, this embodiment further proposes a method for using a grape pruning device for agricultural planting, comprising the following steps:

[0044] Step 1: Hold the adjusting sleeve rod 22 and press the controller to control the motor 1 24 to rotate and drive the adjusting threaded rod 23 to rotate, so that the telescopic rod 21 is adjusted in height under the limit cooperation of the adjusting sleeve rod 22, so that the hawk-beak shear knife 34 is aligned with the grape branch to be pruned;

[0045] Step 2: Continue to operate the motor 2 32 to drive the rotating shaft sleeve 33 to rotate and hook the grape branch, and the branch-grabbing limiting bending rod 41 is driven to keep rotating in the opposite direction to the hawk-beak-shaped shearing knife 34. When the hawk-beak-shaped shearing knife 34 rotates downward to cut, the branch-grabbing limiting bending rod 41 rotates upward to grasp and limit the grape branch, so that the hawk-beak-shaped shearing knife 34 can cut it when it passes between the hawk-beak-shaped shearing knives 34;

[0046] Step three, the processing box 51 is located below the protective shell 1 of the pruning device to receive the grape branches cut by the hawk-beak shearing knife 34, driving the second shaft 55 to rotate the rotating rod 54 through the belt, so that the cutting knife 541 performs a secondary cutting on the grape branches falling on the sliding strip 53 to cut them into small sections, which fall into the processing box 51 along the sliding strip 53 and are then discharged in another direction through the outlet pipe 52.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
