AI Technical Summary
During the pruning of branches of oil tea trees, the existing pruners are prone to falling off directly when used, causing damage to staff, and it is difficult to prune, and the length of the equipment cannot be adjusted freely, so there is insufficient flexibility to adapt to different heights.
A tea branch trimmer is designed, using a ply plate to lift one end of the branch upwards to avoid the clamping state of the branches against the lower cutting knife. At the same time, through the cooperation of the extension sleeve and the extension rod, the equipment length is allowed to be freely adjusted and adapted to different heights.
It effectively avoids clamping the lower cutter during the cutting process, reduces the difficulty of cutting, and improves the flexibility of the equipment through the adjustability of length, and reduces the risk to the staff.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of branch pruning, in particular to a camellia oil branch pruner. Background Art
[0002] Branch pruning is to thin out or shorten certain organs of trees to achieve the purpose of regulating growth, flowering and fruiting. This process includes two main aspects: pruning and shaping. Pruning is mainly to remove some branches so that nutrients are more concentrated on some strong branches, reduce nutrient consumption, and maintain good light and ventilation conditions in the crown;
[0003] During the growth of the oil tea tree, the branches also need to be pruned. When the existing pruners are in use, the staff work under the tree, and the pruned branches are easy to fall directly, which can easily hurt the staff. Therefore, a oil tea branch pruner is proposed. Utility Model Content
[0004] The purpose of the utility model is to provide a tea oil branch trimmer, which can use a splint to lift one end of the branch upwards to avoid the branch from clamping the lower cutter during the cutting process, while reducing the difficulty of cutting. At the same time, the length of the equipment can be freely adjusted to adapt to different heights, thereby improving the flexibility of use and solving the existing technical problems.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] A tea-oil branch pruner comprises: a mounting shell, an upper cutting knife is fixedly connected to the top inner wall of the mounting shell, a lower cutting knife is slidably connected in the mounting shell, the lower cutting knife cooperates with the upper cutting knife and the inner walls are both arranged in an arc shape, a side plate is fixedly connected to one side of the lower cutting knife, a clamping plate for folding branches is fixedly connected to the surface of the side plate, the surface of the clamping plate is arranged in an arc shape and the surface height is higher than the height of the inner circle of the lower cutting knife, by installing the side plate and the clamping plate on one side of the lower cutting knife, when cutting the branch, the clamping plate can be used to push up one end of the branch, so as to avoid the branch from clamping the lower cutting knife during the cutting process, and at the same time reduce the difficulty of cutting;
[0007] The bottom of the installation shell is fixedly connected with a bottom box, the bottom box is slidably connected with a slide plate, the surface of the slide plate is fixedly connected with two slide rods, the slide rods pass through the bottom of the installation shell and are fixed with the lower cutter.
[0008] As a further solution of the utility model, the bottom of the base box is fixedly connected with an external threaded sleeve, the bottom of the slide plate is fixedly connected with a push rod, the push rod slides through the external threaded sleeve, the circumferential thread of the external threaded sleeve is connected with an extension sleeve, a threaded hole is provided at the bottom of the push rod, and an extension rod is threadedly connected to the threaded hole. By using the extension sleeve and the extension rod in coordination, the length of the equipment can be freely adjusted during the use of the mounting shell, thereby adapting to different heights and improving the flexibility of use.
[0009] As a further solution of the utility model, the bottom of the extension sleeve is threadedly connected to a fixing sleeve, the bottom inner wall of the fixing sleeve is fixedly connected to an electric push rod, the output end of the electric push rod is fixedly connected to a connecting shaft, the connecting shaft is located in the threaded hole, and a pin shaft is inserted between the connecting shaft and the extension rod.
[0010] As a further solution of the utility model, a handle is fixedly connected to the bottom of the fixing sleeve.
[0011] As a further solution of the utility model, two guide plates are fixedly connected to one side of the mounting shell, and the two guide plates are arranged in an eight-shaped shape.
[0012] As a further solution of the utility model, a cutting knife is fixedly connected to a side of the mounting shell away from the guide plate.
[0013] In the present application, when in use, the length of the equipment is adjusted according to the use requirements. When adjusting, firstly, the extension rod is threadedly connected to the bottom of the top rod, and then the extension sleeve is threadedly connected to the circumference of the external threaded sleeve, and then the fixed sleeve is connected to the extension sleeve. After connection, the connecting shaft is inserted into the threaded hole at the bottom of the extension rod, and finally the connecting shaft is connected to the extension rod through the pin shaft. It is easy to use. When pruning branches, move the installation shell to the side of the branches that need to be pruned, keep the splint on the side of the branches away from the main trunk of the oil tea, and make the branches between the upper cutter and the lower cutter, and then start the electric push rod, and the electric push rod passes The extension rod, push rod, slide plate and sliding rod drive the lower cutter to rise, and then cooperate with the upper cutter to cut the branch. When the lower cutter rises, the side plate and the clamping plate are driven to rise. Since the height of the clamping plate is greater than the inner circle height of the lower cutter, the clamping plate can be used to lift one end of the branch upward to avoid the branch from clamping the lower cutter during the cutting process, while reducing the difficulty of cutting. After the branch is cut, the clamping plate and the mounting shell can also limit the branch to prevent the branch from falling freely and causing harm to the staff below. Finally, the branch is moved to a safe position, the electric push rod is reset, and the branch can be dropped.
[0014] The embodiments of the present invention have the following beneficial effects:
[0015] In the utility model, by installing the side plate and the clamping plate on one side of the lower cutter, when cutting branches, the clamping plate can be used to push one end of the branch upward, so as to avoid the branch from clamping the lower cutter during the cutting process, and at the same time reduce the difficulty of cutting;
[0016] In the utility model, by using the extension sleeve and the extension rod in coordination, the length of the device can be freely adjusted during the use of the installation shell, thereby adapting to different heights and improving the flexibility of use;
[0017] In the utility model, the clamping plate can be used to push one end of the branch upward to avoid the branch from clamping the lower cutter during the cutting process, thereby reducing the difficulty of cutting. At the same time, the length of the equipment can be freely adjusted to adapt to different heights and improve the flexibility of use.
[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
