Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree pruning tools, in particular to a fruit tree pruning aid. Background Technique

[0002] During the process of agricultural fruit tree planting, it is often necessary to regularly prune the branches of fruit trees. Fruit tree pruning is a technical measure to cut off a part of the vegetative organs of fruit trees to adjust the crown structure and update the branch types. When pruning fruit tree branches, a fruit tree pruning tool is needed for pruning operations.

[0003] For example, the patent with the national authorized patent publication number CN218831389U discloses a fruit tree pruning tool, which includes a pruning knife. The bottom end of the pruning knife is symmetrically fixed with operating handles, and a telescopic mechanism is sleeved on the surface of the operating handles. A protective mechanism is sleeved on the top end of the pruning knife; through the designed guide groove, guide block, limit groove, limit buckle, sliding groove and slider, the length of the extension rod can be adjusted according to the height of the fruit tree, so as to facilitate the use of the fruit tree pruning tool to prune the fruit tree branches at the corresponding height. At the same time, with the designed positioning holes and positioning screws, the length of the extension rod can also be firmly positioned to avoid loosening.

[0004] However, for the above-mentioned fruit tree pruning tool, during the process of pruning branches, the staff needs to keep lifting, which will keep the muscles of the arms and shoulders in a tense state for a long time, resulting in sore and fatigued arm muscles and increasing the physical burden on the staff. It is impossible to directly hang the cutting knife on the outer surface of the branch to be pruned for shearing, and it is impossible to save the lifting force required by the staff. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fruit tree pruning aid to solve the problem that during the process of pruning branches, the staff needs to keep lifting, which will keep the muscles of the arms and shoulders in a tense state for a long time, resulting in sore and fatigued arm muscles and increasing the physical burden on the staff as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fruit tree pruning assistor, comprising: a grip rod, on the upper surface of which a U-shaped frame is fixedly installed, on both sides of the upper surface of the U-shaped frame, top covers are fixedly installed, and in each of the two top covers, a hanging mechanism is rotatably installed. The hanging mechanism can be pushed by the grip rod against the outer surface of the branch to be pruned, and the two hanging mechanisms can rotate inwardly to allow the branch to enter the U-shaped frame. Subsequently, the hanging mechanism can automatically reset and expand to abut against the upper surface of the top cover to close the opening of the U-shaped frame. The U-shaped frame can be hung on the outer surface of the branch to be pruned through the hanging mechanism, thereby saving the force for the staff to lift the grip rod, and further playing an auxiliary role in pruning operations.

[0008] Preferably, a U-shaped groove is formed at one end of the U-shaped frame, and a U-shaped knife is fitted in the U-shaped groove. A guide rod is fixedly installed at the lower end of the outer surface of the U-shaped knife, and the guide rod is slidably installed in the grip rod and fixedly connected to the piston rod of a hydraulic rod, and the hydraulic rod is fixedly installed in the grip rod.

[0009] Preferably, the U-shaped knife can be pushed by the piston rod of the hydraulic rod to slide past one end of the two hanging mechanisms in an intersecting manner, thereby realizing the truncation of the branch in the U-shaped frame.

[0010] Preferably, a flipping groove is formed at one end of the U-shaped frame, so that when the hanging mechanism is pushed and flipped, it can slide into the flipping groove to avoid the branch from entering the U-shaped frame.

[0011] Preferably, the hanging mechanism includes a rotating cylinder, on the outer surface of which a turntable is rotatably installed, and a cutting knife is fixedly installed on the outer surface of the turntable, so that the cutting knife can rotate through the turntable to abut against the lower surface of the top cover to keep horizontal and close the opening of the U-shaped frame.

[0012] Preferably, a torsion spring is fixedly connected inside the rotating cylinder, and the other end of the torsion spring is fixedly connected to the outer surface of a connecting column. The connecting column is fixedly installed in the turntable and inserted into the rotating cylinder.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Through the design of the U-shaped frame, U-shaped knife, top cover, hydraulic rod and hanging mechanism, when pruning branches, the staff can hold the outer surface of the grip rod, align the U-shaped frame with the outer surface of the branch to be pruned and push it. As a result, the U-shaped frame can drive the two hanging mechanisms rotatably installed in the two top covers to touch the outer surface of the branch to be pruned. Then, the hanging mechanism can rotate inward to allow the branch to enter the U-shaped frame. After the branch enters the U-shaped frame, the hanging mechanism will not be touched by the branch. The two hanging mechanisms will automatically flip and reset through the torsional force and touch the upper surface of the top cover horizontally. Thus, the hanging mechanism can close the opening of the U-shaped frame, and the U-shaped frame can be hung on the outer surface of the branch to be pruned through the hanging mechanism, saving the staff the effort of lifting the grip rod, and then playing an auxiliary pruning operation. Subsequently, the staff only needs to support the grip rod to activate the hydraulic rod to push the U-shaped knife to cut the lower half of the branch. At the same time, the hanging mechanism will also cut the upper half of the branch, realizing the operation of cutting the branch by the U-shaped knife and the hanging mechanism.

[0015] 2. Through the design of the rotating cylinder, torsion spring, turntable, connecting column and cutting knife, when pruning branches, the staff can hold the outer surface of the grip rod, align the U-shaped frame with the outer surface of the branch to be pruned and push it. As a result, the U-shaped frame can drive the two cutting knives rotatably installed in the two top covers to touch the outer surface of the branch to be pruned. Then, the cutting knife can rotate inward into the flipping groove on the outer surface of the rotating cylinder through the turntable to allow the branch to enter the U-shaped frame. And when the turntable is driven to rotate on the outer surface of the rotating cylinder, it will drive the torsion spring fixedly connected to the outer surface of the connecting column to twist together. Thus, the torsion spring can apply a reverse force to the turntable. After the branch enters the U-shaped frame, the cutting knife will not be touched by the branch. The two cutting knives will automatically flip and reset through the reverse force applied by the torsion spring and touch the upper surface of the top cover horizontally. Thus, the two cutting knives can close the opening of the U-shaped frame, and the U-shaped frame can be hung on the outer surface of the branch to be pruned through the cutting knife, saving the staff the effort of lifting the grip rod, and then playing an auxiliary pruning operation. And hanging the U-shaped frame on the branch reduces the force required to keep the tool stable during pruning, reduces the labor intensity of the staff. Especially during long-term pruning work, it can effectively relieve arm fatigue. Compared with simply holding the pruning tool by hand, it reduces the risk of the tool accidentally slipping due to operating errors or arm fatigue, ensuring the safety of the staff and items under the tree.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 - 5 The present embodiment provides a fruit tree pruning assistant, comprising: a grip 1, a U-shaped frame 101 is fixedly installed on the upper surface of the grip 1, top covers 105 are fixedly installed on both sides of the upper surface of the U-shaped frame 101, and hanging mechanisms 2 are rotatably installed in two sets of top covers 105, the hanging mechanisms 2 can be pushed onto the outer surface of the branch to be pruned through the grip 1, and the two sets of hanging mechanisms 2 can be rotated inward to allow the branch to enter the U-shaped frame 101, and then the hanging mechanisms 2 can be automatically reset and expanded to touch the upper surface of the top cover 105 to close the opening of the U-shaped frame 101, so that the U-shaped frame 101 can be hung on the outer surface of the branch to be pruned through the hanging mechanisms 2, thereby saving the staff the power to lift the grip 1, thereby assisting the pruning operation.

[0024] A U-shaped groove 106 is provided at one end of the U-shaped frame 101, and a U-shaped knife 102 fits in the U-shaped groove 106. A guide rod 103 is fixedly installed at the lower end of the outer surface of the U-shaped knife 102. The guide rod 103 is slidably installed in the grip rod 1 and fixedly connected to the piston rod of the hydraulic rod 107. The hydraulic rod 107 is fixedly installed in the grip rod 1.

[0025] The U-shaped knife 102 can be pushed by the piston rod of the hydraulic rod 107 to slide past one end of the two groups of hanging mechanisms 2 in an interleaved manner, so as to realize the truncation of the branches in the U-shaped frame 101.

[0026] One end of the U-shaped frame 101 is provided with a flipping groove 104, so that when the hanging mechanism 2 is pressed and flipped, it can slide into the flipping groove 104 to avoid branches entering the U-shaped frame 101.

[0027] Through the design of the U-shaped frame 101, U-shaped knife 102, top cover 105, hydraulic rod 107 and hanging mechanism 2, when pruning branches, the staff can hold the outer surface of the grip rod 1 and align the U-shaped frame 101 with the outer surface of the branches to be pruned and push, so that the U-shaped frame 101 can drive the two groups of hanging mechanisms 2 rotatably installed in the two top covers 105 to touch the outer surface of the branches to be pruned. Furthermore, the hanging mechanism 2 can rotate inward to allow the branches to enter the U-shaped frame 101. After the branches enter the U-shaped frame 101, the hanging mechanism 2 will not be touched by the branches, and the two groups of hanging mechanisms 2 will automatically flip and reset through the torsional force and touch the upper surface of the top cover 105 in a horizontal state. Furthermore, the hanging mechanism 2 can close the opening of the U-shaped frame 101, and the U-shaped frame 101 can be hung on the outer surface of the branches to be pruned through the hanging mechanism 2, thus saving the force for the staff to lift the grip rod 1, and then playing an auxiliary pruning operation. Subsequently, the staff only needs to support the grip rod 1 to start the hydraulic rod 107 to push the U-shaped knife 102 to cut the lower half of the branches, and at the same time, the hanging mechanism 2 will also cut the upper half of the branches, realizing the operation of cutting the branches by the U-shaped knife 102 and the hanging mechanism 2.

[0028] As Figure 5 shown, the hanging mechanism 2 includes a rotating cylinder 201. A turntable 203 is rotatably installed on the outer surface of the rotating cylinder 201, and a cutting knife 205 is fixedly installed on the outer surface of the turntable 203, so that the cutting knife 205 can rotate through the turntable 203 and touch the lower surface of the top cover 105 to keep horizontal to close the opening of the U-shaped frame 101.

[0029] A torsion spring 202 is fixedly connected inside the rotating cylinder 201, and the other end of the torsion spring 202 is fixedly connected to the outer surface of the connecting column 204. The connecting column 204 is fixedly installed in the turntable 203 and inserted into the rotating cylinder 201.

[0030] Through the design of the rotary drum 201, torsion spring 202, turntable 203, connecting column 204 and cutter 205, when pruning branches, the staff can hold the outer surface of the grip rod 1 and align the U-shaped frame 101 with the outer surface of the branch to be pruned and push it. Then, the U-shaped frame 101 can drive the two cutters 205 rotatably installed in the two top covers 105 to touch the outer surface of the branch to be pruned. Then, the cutter 205 can rotate inward from the outer surface of the rotary drum 201 into the flipping groove 104 through the turntable 203 for the branch to enter the U-shaped frame 101. And when the turntable 203 is driven to rotate on the outer surface of the rotary drum 201, it will drive the torsion spring 202 fixedly connected to the outer surface of the connecting column 204 to twist together. Then, the torsion spring 202 can apply a reverse force to the turntable 203. After the branch enters the U-shaped frame 101, the cutter 205 will not be touched by the branch. And the two cutters 205 will automatically flip and reset through the reverse force applied by the torsion spring 202 and touch the upper surface of the top cover 105 horizontally. Then, the two cutters 205 can close the opening of the U-shaped frame 101, and the U-shaped frame 101 can hang on the outer surface of the branch to be pruned through the cutter 205, thus saving the strength of the staff to lift the grip rod 1, and then playing an auxiliary pruning operation. And hanging the U-shaped frame 101 on the branch reduces the force required to keep the tool stable during pruning, reduces the labor intensity of the staff. Especially during long-term pruning work, it can effectively relieve arm fatigue. Compared with simply holding the pruning tool by hand, it reduces the risk of the tool accidentally slipping due to operation errors or arm fatigue, and ensures the safety of the staff and items under the tree.

[0031] Summarize and sort out the working steps of this solution according to the above technical solution: When pruning branches, the staff can hold the outer surface of the grip rod 1 and align the U-shaped frame 101 with the outer surface of the branch to be pruned and push it, so that the U-shaped frame 101 can drive the two cutting knives 205 rotatably installed in the two top covers 105 to touch the outer surface of the branch to be pruned. Then, the cutting knives 205 can rotate inward into the flipping groove 104 on the outer surface of the rotating cylinder 201 through the turntable 203 to allow the branch to enter the U-shaped frame 101. When the turntable 203 is driven to rotate on the outer surface of the rotating cylinder 201, it will also drive the torsion spring 202 fixedly connected to the outer surface of the connecting column 204 to twist. Thus, the torsion spring 202 can apply a reverse force to the turntable 203. After the branch enters the U-shaped frame 101, the cutting knives 205 will not be touched by the branch. The two cutting knives 205 will automatically flip and reset through the reverse force applied by the torsion spring 202 and touch the upper surface of the top cover 105 horizontally. Then, the two cutting knives 205 can close the opening of the U-shaped frame 101, enabling the U-shaped frame 101 to be hung on the outer surface of the branch to be pruned through the cutting knives 205. Subsequently, the staff only needs to support the grip rod 1 to start the hydraulic rod 107 to push the U-shaped knife 102 to cut the lower half of the branch. At the same time, the cutting knives 205 will also cut the upper half of the branch together, realizing the operation of cutting the branch by the U-shaped knife 102 and the cutting knives 205. After cutting the branch, the closed U-shaped frame 101 can be removed from the outer surface of the branch.

[0032] In summary: During the process of pruning branches, this fruit tree pruning assistor can be hung on the outer surface of the branch, saving the staff the effort of lifting the grip rod 1, thus assisting in the pruning operation. It also reduces the force required to keep the tool stable during pruning, reduces the labor intensity of the staff, and compared with simply holding the pruning tool by hand, reduces the risk of accidental slipping of the tool due to operation errors or arm fatigue, ensuring the safety of the staff and items under the tree.
