Picking execution end device with three-stage buffering

Abstract

The invention discloses a picking execution end device with three-stage buffering. The picking execution end device comprises a straight pipe, a negative pressure cavity outer wall, a buffer cavity outer wall and a fallen fruit outlet, wherein one end of the negative pressure cavity outer wall is fixedly connected to the buffer cavity outer wall, the other end of the negative pressure cavity outerwall is connected to the outer wall of the straight pipe, a negative pressure cavity is formed between the negative pressure cavity outer wall and the straight pipe outer wall, and a buffering cavityis formed in the outer wall of a buffer cavity and communicates with the negative pressure cavity; a straight pipe buffer surface attached to the straight pipe is arranged in the straight pipe, and abuffer cavity buffer surface is arranged on the lower inner wall of the separation wall close to the straight pipe side at a fallen fruit outlet; and a concave buffer surface is arranged on the innerwall of the buffer cavity shell far away from the straight pipe side at the fallen fruit outlet. According to the device, three-stage buffering is arranged, so that better fruit picking quality can be obtained; by arranging the straight pipe buffer surface on the inner side of the straight pipe, effective air inlet area can be reduced, larger suction force can be obtained on the premise that theefficiency of a fan is not changed, a negative pressure utilization rate is increased, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of intelligent picking, and more specifically, to a picking execution terminal device with three-level buffering. Background technique [0002] Currently fruit picking and harvesting is still largely a manual process. In orchards where the fruit grows on trees, such as apple, pear, and peach orchards, farm workers move ladders near the trees, climb the ladders, pick the fruit, and transfer the fruit to temporary storage such as baskets. After the worker has picked all the ripe fruit in that location, the worker climbs down and moves the ladder to another location, then repeats the process as many times as necessary. As labor costs continue to rise, the difficulty of hiring labor for fruit growers has become increasingly apparent. It is even more economical to let fruit rot on the tree than hiring people to pick it. Automatic and intelligent picking has become a research hotspot. [0003] At present, the research of ...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that the existing fruit collection end effector is easy to cause loss to the fruit during the fruit collection process, and proposes a picking execution end device with three levels of buffering, which can effectively reduce the damage caused by the fruit during the picking process. damage
