Agricultural pruning and felling mechanism

Abstract

The invention discloses an agricultural pruning and felling mechanism. The agricultural pruning and felling mechanism comprises a machine frame and a shaft sleeve vertically installed on the top end face of the machine frame. The lower end of the shaft sleeve is inserted inside the machine frame and can freely rotate in the machine frame, a horizontal strip plate is fixedly connected to the outer side wall of the upper end of the shaft sleeve, circular grooves are formed in the inner walls at the upper end and the lower end in the shaft sleeve respectively, a torsion spring is located in the shaft sleeve, spring wire heads at the two ends of the torsion spring are firmly clamped into the two circular grooves respectively, a rotating shaft penetrating through the shaft sleeve is fixedly sleeved with the torsion spring, a first external gear is arranged at the bottom end of the rotating shaft and matched with a second external gear, the second external gear is engaged with an internal gear, the first external gear and the internal gear are concentric, a gear shaft of the second external gear is vertically arranged at the bottom of the machine frame and can freely rotate, a stepped shaft capable of being inserted into a bearing in the machine frame is arranged on the bottom end face of the internal gear, and sawteeth are evenly arranged on the external circle face of the internal gear. The agricultural pruning and felling mechanism is safe in using, labor is saved, and the agricultural pruning and felling mechanism can be used for replacing a pruning shear for manual work.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a device for cutting melons, fruits and trees. Background technique [0002] With the development of social economy and the improvement of people's consumption level, in order to meet the huge market demand, the existing melons and fruits are all planted in batches on farms. In order to make it bear better fruit in the coming year, fruit trees are often pruned, or old fruit trees are cut down. Due to the huge number of fruit trees in a forest, pruning and felling require a lot of manpower and time. Therefore, every In the season of taking care of fruit trees, the number of forest managers is far from enough. In addition, at present, pruning is done manually with large scissors, which is also time-consuming and labor-intensive, and the efficiency is extremely low. Although there are pruning machines for greening, it is not suitable for selective fruit tree pruning...

[0002] With the development of social economy and the improvement of people's consumption level, in order to meet the huge market demand, the existing melons and fruits are all planted in batches on farms. In order to make it bear better fruit in the coming year, fruit trees are often pruned, or old fruit trees are cut down. Due to the huge number of fruit trees in a forest, pruning and felling require a lot of manpower and time. Therefore, every In the season of taking care of fruit trees, the number of forest managers is far from enough

In addition, at present, pruning is done manually with large scissors, which is also time-consuming and labor-intensive, and the efficiency is extremely low. Although there are pruning machines for greening, it is not suitable for selective fruit tree pruning, and existing Cutting equipment is easy to slip when in contact with branches or trunks, resulting in safety accidents. Therefore, there is an urgent need for a device that can replace large shears for pruning and felling, and can also ensure the safety of pruning and cutting to help forest managers. take good care of fruit trees
