Picking-assisting mechanical arm clamping structure

Abstract

The invention discloses a picking-assisting mechanical arm clamping structure. The picking-assisting mechanical arm clamping structure comprises a fixed rod, wherein two connecting rods are rotationally connected to the fixed rod, a first pulling rod and a second pulling rod are rotationally connected to the ends, away from the fixed rod, of the two connecting rods respectively, the middle of the first pulling rod and the middle of the second pulling rod are hinged, a rod pushing motor is connected between the first pulling rod and the second pulling rod, the two ends of the rod pushing motor are rotationally connected with the outer wall of the first pulling rod and the outer wall of the second pulling rod respectively, clamping blocks are connected to the top of the first pulling rod and the top of the second pulling rod respectively, tool aprons are arranged on the outer walls of the adjacent sides of the two clamping blocks respectively, and grooves are formed in the outer walls of the sides, away from the clamping blocks, of the tool aprons. The picking-assisting mechanical arm clamping structure is simple in structure and reasonable in design, saves time and labor, can prevent branches from slipping off and can conduct buffering when two blades get close, the situation that when getting close, the two blades bear large stress and generate abrasion is avoided, and therefore the service life of the clamping structure can be prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a picking structure of a power-assisted mechanical arm for picking. Background technique [0002] With the progress and development of society, the transportation is more and more convenient, and people can enjoy fruits all over the world, but the height of fruit trees increases with time, and the growth of fruit trees brings certain difficulties to fruit picking. It is easy to fall from a height when it is picked or the fruit grower climbs the tree, which directly affects the economic benefit and life safety of the fruit grower. Therefore, there are manipulators on the market that can easily pick high places or places that are inconvenient for human hands to replace manual picking. However, the gripping device of the existing manipulator cannot fix the branches of the fruit tree, and it is easy to make the root of the fruit deviate, which reduces the stability of grippin...

[0002] With the progress and development of society, the transportation is more and more convenient, and people can enjoy fruits all over the world, but the height of fruit trees increases with time, and the growth of fruit trees brings certain difficulties to fruit picking. It is easy to fall from a height when it is picked or the fruit grower climbs the tree, which directly affects the economic benefit and life safety of the fruit grower. Therefore, there are manipulators on the market that can easily pick high places or places that are inconvenient for human hands to replace manual picking. However, the gripping device of the existing manipulator cannot fix the branches of the fruit tree, and it is easy to make the root of the fruit deviate, which reduces the stability of gripping. In order to ensure the integrity of the fruit and improve economic benefits, the gripping structure of the manipulator should be improved. Improve
