Abstract
Description
Technical Field
[0001] This utility model relates to the field of horticulture technology, specifically to a tree branch pruning device. Background Technology
[0002] Horticulture, also known as garden cultivation, encompasses the cultivation, propagation techniques, and production and management methods of fruit trees, vegetables, and ornamental plants. Currently, with people paying more and more attention to the green environment around them, the planting volume of horticultural trees has increased significantly. Horticultural pruning refers to the method of removing overgrown branches, drooping branches, back branches, overly dense branches, diseased and insect-infested branches, and weak branches from trees. Pruning horticultural trees can effectively shape them and give them a better aesthetic effect.
[0003] Most existing pruning equipment for garden trees involves first fixing a hand saw to one end of a long pole, then holding the pole to move the hand saw to prune the branches of the garden trees. However, when using existing pruning equipment for garden trees, users need to hold the long pole for a long time to move the hand saw to cut and prune the branches, which increases the labor intensity of the user and affects the pruning efficiency.

[0030] The present invention will be further described in detail below with reference to embodiments:
[0031] Example 1
[0032] like Figure 1-6As shown, this utility model provides a tree branch pruning device, including a pruning mechanism 1, a support mechanism 2 at the bottom of the pruning mechanism 1, and a battery backpack 3 on the side of the support mechanism 2. The pruning mechanism 1 includes an equipment box 101, a mounting plate 102 rotatably connected inside the equipment box 101, a motor 103 fixedly connected to the side of the mounting plate 102, a rotating shaft rotatably connected inside the mounting plate 102, a cutting disc 104 fixedly connected to one end of the rotating shaft, a fixing plate 105 fixedly connected inside the equipment box 101, and a roller 106 rotatably connected to the side of one end of the fixing plate 105. There is a rotating plate 107 and a tension spring 108. One end of the rotating plate 107 is rotatably connected to a roller 109. One end of the tension spring 108 is rotatably connected to the rotating plate 107. A cylinder 110 is fixedly connected to the side of the equipment box 101. The telescopic end of the cylinder 110 slides through the side of the equipment box 101 and is rotatably connected to the mounting plate 102. The output shaft of the motor 103 rotatably passes through the side of the mounting plate 102 and is fixedly connected to a pulley 111. A belt 112 is movably connected to the outer ring of the pulley 111. The other end of the rotating shaft is fixedly connected to a pulley 113. The pulley 113 is movably connected to the pulley 111.
[0033] In this embodiment, when pruning branches, the equipment box 101 is lifted to one side of the branch by the support mechanism 2. Roller 106 and roller 209 come into contact with the branch. When roller 209 comes into contact with the branch, it drives the rotating plate 107 to rotate. When the rotating plate 107 rotates, it stretches the tension spring 108. The tension spring 108 drives roller 209 to press tightly against the branch through the rotating plate 107. Roller 106 and roller 209 clamp the branch, thereby restricting the position of the equipment box 101. Roller 106 and roller 209 support the equipment box 101 through the fixing plate 105, the rotating plate 107, and the tension spring 108, reducing the labor intensity of the user. The motor 103 and cylinder 110 are started. The motor 103 drives the cutting disc 104 to rotate through pulley 111, belt 112, pulley 113 and shaft. The cylinder 110 extends and drives the mounting plate 102 to rotate. When the mounting plate 102 rotates, it drives the cutting disc 104 to move towards the branch. The cutting disc 104 cuts and prunes the branch. Rollers 106 and 109 limit the position of the equipment box 101 through the fixing plate 105, rotating plate 107 and tension spring 108, which improves the stability of the cutting disc 104 during cutting and pruning. The cutting disc 104 cuts and prunes the branch, reducing the labor intensity of the user and improving the pruning efficiency of the branch.
[0034] After the branches are pruned, the cylinder 110 is started to drive the mounting plate 102 to rotate. The mounting plate 102 drives the cutting disc 104 into the equipment box 101. The equipment box 101 can protect the cutting disc 104 and prevent it from colliding with external objects and causing damage to the cutting disc 104.
[0035] Example 2
[0036] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support mechanism 2 includes a support rod 201, a telescopic rod 202 is slidably connected inside the support rod 201, a step plate 203 is fixedly connected to the top of the telescopic rod 202, a protective cover 204 is fixedly connected to the top surface of the step plate 203, the step plate 203 is fixedly connected to the equipment box 101, a through hole is opened on the outer surface of the top of the support rod 201, a limit hole 205 is linearly arrayed on the outer surface of the telescopic rod 202, a limit pin 206 is slidably connected inside the through hole and the limit hole 205, a groove 207 is opened at one end of the limit pin 206, a semi-circular block 208 is slidably connected inside the groove 207, a spring 209 is fixedly connected inside the groove 207, and one end of the spring 209 is fixedly connected to the semi-circular block 208.
[0037] In this embodiment, before pruning the branches, the telescopic rod 202 is pulled out of the support rod 201 according to the height of the branches, thereby adjusting the total length of the support rod 201 and the telescopic rod 202. After adjusting to a suitable length, the limiting pin 206 is inserted into the through hole and the corresponding limiting hole 205. The limiting pin 206 fixes the total length of the support rod 201 and the telescopic rod 202. When one end of the limiting pin 206 enters the through hole and the limiting hole 205, the semicircular block 208 and the through hole and The inner wall of the limiting hole 205 contacts the through hole and the limiting hole 205, causing the semicircular block 208 to slide into the slide groove 207. When the semicircular block 208 slides, it causes the spring 209 to contract. When one end of the limiting pin 206 passes through the through hole and the limiting hole 205, the spring 209 relaxes and causes the semicircular block 208 to slide out of the slide groove 207. The semicircular block 208 can prevent the limiting pin 206 from falling out of the through hole and the limiting hole 205 during use, thus improving the safety of the support rod 201 and the telescopic rod 202.
[0038] When pruning tree branches, the user holds the support rod 201, which drives the equipment box 101 to rise to the side of the tree branch through the telescopic rod 202 and the step plate 203. The cutting disc 104 cuts and prunes the tree branch. The protective cover 204 can block the pruned tree branch to prevent it from hitting the user and improving the user's work safety. In addition, the protective cover 204 is made of transparent material, which makes it easy for the user to observe the pruning of the tree branch.
[0039] Example 3
[0040] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a battery is fixedly connected inside the battery backpack 3, and the battery is electrically connected to the motor 103 and the cylinder 110 through wires.
[0041] In this embodiment, the battery is stored in the battery backpack 3, which makes it convenient for the user to carry the battery. The battery is electrically connected to a controller via wires. The controller can control the start and stop of the motor 103 and the cylinder 110, which is convenient for the user to operate.
[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
