Embodiment 1

[0021] The structure and assembly of the electric grape branch pruning machine of this embodiment are as attached figure 1 shown.

[0022] In this embodiment, the motor 1 and the power transmission mechanism are assembled and connected with the simplest keyway structure, that is, the power output shaft of the motor and the transmission shaft of the power transmission mechanism are on the same axis, and the key head at the end of the power output shaft of the motor is inserted into the power transmission mechanism. In the groove of the drive shaft of the transmission mechanism.

[0023] See attached figure 1 , the power transmission mechanism of this embodiment is formed by upper cover 2, pressing plate 3, double crank shaft plate 4, upper and lower connecting rods 5 and housing 7, and the housing 7, pressing plate 3 and housing upper cover 2 combine the hyperbolic The shaft plate 4 and the upper and lower connecting rods 5 are axially limited, and the convex key at the end o...

Embodiment 2

[0029] In this embodiment, the power transmission mechanism, blade angle adjustment mechanism, extension bar and power control switch are the same as those in Embodiment 1, the difference is that the motor used in this embodiment is a composite motor with a gear transmission mechanism. It is a combination of ordinary DC brushed motor and variable speed gearbox.

[0030] The composite motor structure of this embodiment is as attached image 3As shown, the composite motor is composed of three axial parts: a DC brushed motor, a cooling fan, and a gear box. The DC brushed motor is fixedly connected with the motor fixing plate 42, the gear box upper cover 43 and the gear box case 44 through the positioning pin 41 to form a whole. The reversing carbon brushes 34 of the motor, the cooling fan 35 and the gear box are all arranged along the axial direction of the motor rotor main shaft 31 . The cooling fan 35 is arranged on the top of the motor rotor main shaft 31 , and the motor rev...

Abstract

The invention relates to an electric grape branch pruner. The electric grape branch pruner is characterized in that the lower end of a center shaft of a double-crankshaft disk of a power transmission mechanism is inserted into a positioning hole of a shell, a protruding eccentric boss is arranged on the upper surface of a circular base disk of the double-crankshaft disk as well as one on the lower surface of the circular base disk, the circular center of the protruding eccentric boss of the upper surface and the circular center of the protruding eccentric boss of the lower surface are arranged on the same diameter line of the circular base disk (22B), one end of an upper connecting rod is sleeved with the boss on the upper surface, and the other end of the upper connecting rod is sleeved with a boss at a root end of a double-edge blade. A spline of an end of an output shaft of a motor penetrates an upper cover of the shell and a press plate through hole to be inserted into a notch of the upper end of a mandrel in the double-crankshaft disk. A gear change mechanism and a motor structure are integrated, total weight of the electric grape branch pruner is reduced, the edges of the blade are lengthened and broadened, pruning quality and efficiency are improved, labor intensity of operators is alleviated, and the electric grape branch pruner with a 12V 20-ampere-hour lithium battery can work continuously for 8-10 hours.

Description

technical field [0001] The invention belongs to garden and orchard operating machines, in particular to an electric machine mainly used for pruning grape vines and branches. Background technique [0002] Pruning of vines and branches is a regular task in vineyard management. At present, the most common method is to cut off manually or with scissors. The difficulty of scissors pruning increases, and even needs to step on the height. However, the trimming machine with gasoline engine as the power source solves the problems of trimming height and trimming efficiency by lengthening the handle, but the gasoline engine has a series of exhaust emissions, pollution, noise, high fuel cost, and difficulty in gasoline engine maintenance. The reason makes it difficult to be commonly used in the pruning of vineyard vines and branches. Contents of the invention [0003] The purpose of the present invention is to provide an electric grape pruning machine with DC power supply as the pow...
