Backpack type fruit tree trimming device

Abstract

The invention discloses a backpack type fruit tree trimming device which comprises a gasoline engine, a saw blade protection cover, an electronic telescopic rod, a mounting rod, a holding net, a connecting rod and a fan. The backpack type fruit tree trimming device is scientific and reasonable in structure and safe and convenient to use; due to arrangement of the saw blade protection cover, a sawblade can be protected, the saw blade can be prevented from collision with other articles in daily holding and taking and transportation processes, furthermore saw teeth on the saw blade can be prevented from being blunt, the service life of the saw blade is prolonged, and the replacement cost of the saw blade is reduced; meanwhile, the electronic telescopic rod drives the mounting rod to be expanded through the connecting rod, the holding net is expanded by the mounting rod, then an inverted umbrella-shaped structure is formed, on one hand, the holding net is capable of preventing cut twigs from falling down to hurt operators, and on the other hand, the twigs can be collected by the holding net, so that later collection trouble can be avoided; and in addition, due to adoption of the fan,a function of heat radiation can be achieved for the operators in hot summer.

Description

technical field [0001] The invention relates to the technical field of fruit tree pruning, in particular to a backpack type fruit tree pruning device. Background technique [0002] Cutting off some of the branches on the tree is conducive to the absorption of nutrients and water by the main branches, which is convenient for its growth. Only by cutting them off can the health of the tree and the appearance of the tree be maintained. [0003] The saw blades of the existing pruning devices are exposed when they are placed and used in daily life. Especially when they are picked up and transported, the saw blades are very likely to touch hard objects, which will cause the blades of the saw blades to no longer be sharp and affect the For the pruning efficiency of the pruning device, if you replace the saw blade with a new one, you will have to increase the cost, because the saw blade is relatively large. When pruning fruit trees, the high-speed saw blade often touches the fruiting...

Problems solved by technology

[0003] The saw blades of the existing pruning devices are exposed when they are placed and used in daily life. Especially when they are picked up and transported, the saw blades are very likely to touch hard objects, which will cause the blades of the saw blades to no longer be sharp and affect the For the pruning efficiency of the pruning device, if you replace the saw blade with a new one, you will have to increase the cost, because the saw blade is relatively large. When pruning fruit trees, the high-speed saw blade often touches the fruiting branches. Once touched, it will cause the branches that do not need to be pruned to fall, which will reduce the number of fruit trees' final results, thereby reducing the income of the fruit farmers. Loud noise, the noise will affect the mood of the user, and may make the user passive and slow down, and the user is in a noisy environment for a long time, which will also have a bad impact on the personal hearing. Therefore we propose a kind of backpack type fruit tree pruning device
