Description

A picking and shearing device

technical field

The invention relates to an agricultural machine, in particular to a picking and shearing device.

Background technique

At present, when the fruit on the tree is picked, it is generally picked by hand or by simple tools, which has a great disadvantage: artificial picking is generally picked by pulling branches under the tree, climbing trees or picking with ladders, and the above methods are either easy Pulling off the branches of the fruit tree is likely to cause danger; while using a simple tool is to use a penny to beat or cut a V-shaped fork on the top of the penny to clamp the fruit. Although this method is safe, it is easy to use too many pennies. Cracking, and the fruit is easy to be knocked or dropped to the ground, which will affect the appearance and storage, and reduce the income. The fruit stalk is generally tough and not easy to break, and needs to be cut off with scissors, and the fruit growth position on the fruit tree is irregular. Therefore, need to develop a kind of electric shearing, and the picking tool that can adjust the knife edge position flexibly.

The motor fixing cylinder is connected to the slider 2 through the second rotating pair, the handle is fixed under the motor fixing cylinder, the passive blade is fixed at the front end of the motor fixing cylinder, the limit nail 1 and the limit nail 2 are fixed on the passive blade, and the active blade is located on the passive blade. On the blade, the active blade is provided with a chute one and a chute two, and the chute one and the two chute cooperate with the limit nail one and the limit nail two respectively, the slide block one is fixed on the knife back of the active blade, and the slide block one A vertical chute is set at the end away from the active blade, the motor is fixed on the motor fixing cylinder, one end of the eccentric shaft is fixed at the position where the output shaft of the motor deviates from the axis, and one end of the eccentric shaft is embedded in the vertical chute of slider one , the horizontal width of the vertical chute is the same as the diameter of the eccentric shaft, and the vertical length of the vertical chute is greater than the diameter of the eccentric shaft.

The outstanding advantages of the present invention are:

1. The motor provides power, and the shearing force is large, which can easily cut off the fruit handle and reduce the physical exertion of the fruit grower.

2. It is easy to operate and has multiple degrees of freedom. It can flexibly adapt to changes in the position of the fruit, and accurately align the stem of each fruit for cutting without damaging the fruit tree and fruit.

3. The concept is novel, the structure is compact, the manufacture is relatively simple, the operation is stable, the operation is safe, the performance is good, the design is compact and ingenious, simple and practical, convenient and safe, and suitable for home use.

detailed description

The technical solution of the present invention will be further elaborated below through examples.

Example 1

A picking and shearing device, comprising a handle 1, a motor 2, a motor fixing cylinder 3, an eccentric shaft 4, a slider 5, an active blade 6, a passive blade 7, a limit nail 9, a limit nail 2 10, and a vehicle frame 11. The first column 12, the second column 14, the beam 15 and the slider 2 16,

The lower end of the first column 12 is fixed on the vehicle frame 11, the upper end of the first column 12 is connected with the lower end of the second column 14 through the first rotating pair 13, and the upper end of the second column 14 is fixed on the beam 15, which is provided with a horizontal chute , slide block 2 16 is installed in the horizontal chute,

The motor fixing cylinder 3 is connected on the slide block 2 16 through the second rotating pair, the handle 1 is fixed below the motor fixing cylinder 3, the passive blade 7 is fixed on the front end of the motor fixing cylinder 3, and the passive blade 7 is fixed with a limit nail 9 and a limit screw. Position nail two 10, active blade 6 is positioned on passive blade 7, and active blade 6 is provided with chute one and chute two, and chute one and chute two cooperate with limit nail one 9 and limit nail two 10 respectively, The slider one 5 is fixed on the knife back of the driving blade 6, the end of the slider one 5 far away from the driving blade 6 is provided with a vertical chute, the motor 2 is fixed on the motor fixing cylinder 3, and one end of the eccentric shaft 4 is fixed on the output shaft of the motor 2 At the position deviated from the axis, one end of the eccentric shaft 4 is embedded in the vertical chute of the slider one 5, the horizontal width of the vertical chute is the same as the diameter of the eccentric shaft 4, and the vertical length of the vertical chute is greater than the eccentric The diameter of shaft 4.

working principle

Push the vehicle frame 11 and move the overall device to the side of the pepper tree, the second column 14 and the first column 12 can freely rotate through the first rotating pair 13, and the slide block 2 16 slides to the horizontal chute on the crossbeam 15. The position suitable for cutting work, and because the motor fixing cylinder 3 is connected to the slider 2 16 through the second rotating pair, the direction of the motor is further fine-tuned through the handle 1 .

At this time, the motor 2 is started, and the motor 2 drives the eccentric shaft 4 to make a circular motion around the shaft of the motor 2. Due to the limit function of the vertical chute, the slider 15 is reciprocated in the horizontal direction, and at the same time it is driven and fixed on it. The active blade 6 slides back and forth in the horizontal direction, and the chute 1 and the chute 2 cooperate with the limit nail 9 and the limit nail 2 10 respectively, so that the sliding of the active blade is stable. When the active blade 6 and the passive blade 7 overlap , to achieve the function of cutting objects between the two.
