Problems solved by technology

So far, my country has not independently developed an automatic transfer machine for plug seedlings to be applied to production. Although Taiwan, Nanjing Agricultural University, Shenyang Agricultural University and other units have trial-produced some seedling-taking end effectors similar to four-finger claws, the structure is simple, but the finger It has been fixed and formed, and only four clamping needles are used to stretch and retract in the mechanical fingers to achieve seedlings. The flexibility is poor, and it is difficult to avoid the occurrence of seedling injury.

Embodiment Construction

[0016] Such as figure 1 As shown, the overall structure of the present invention is composed of a mechanical cantilever sleeve, a mechanical finger skeleton, a mechanical finger joint, a rubber finger, a miniature cylinder, a mechanical limit block, a mechanical finger sleeve, a gripping needle, a spring, and the like. The specific layout of each kinematic pair and parts is as follows: the mechanical cantilever sleeve 1 is installed on the seedling picking frame, and its installation position can be adjusted by rotation. The mechanical finger skeleton 2 is configured on the mechanical cantilever sleeve 1 for hanging two mechanical Finger joints 3, each mechanical finger joint 3 is connected with the mechanical finger frame 2 through a rotating pair, so that the mechanical finger joint 2 can flexibly swing, the rubber finger 4 is fixedly connected to the mechanical finger frame 2, and the airbag of the rubber finger 4 bears against the two A mechanical finger joint 3, each mech...

Abstract

The invention discloses a two-finger four-pin automatic picking and placing device for plug seedling transplanting. The device comprises a mechanical cantilever sleeve 1, a mechanical finger frame 2, rubber fingers 4, a support rod 5 and a mechanical finger spacing block 9 which are fixedly connected in sequence along the direction of the same center line, wherein each mechanical finger comprises a mechanical finger joint 3, a micro-cylinder 6, a mechanical finger sleeve 7, a clamping pin spacing block 11 with a longitudinal spacing groove and a clamping pin 14 which can slide in the longitudinal spacing groove and is fixedly connected with a piston rod of the micro-cylinder 6; the upper ends of the mechanical finger joints 3 are symmetrically hinged on two sides of the mechanical finger frame 2; the mechanical finger sleeve 7 passes through the chute of the mechanical finger spacing block 9, and can move in the chute along the chute direction; the two mechanical fingers and the support rod are pre-tightened together through a tightening spring 8; and the tightening spring 8 is positioned on one side of the mechanical finger spacing block 9, far from the tail end of the mechanical finger, and is close to the mechanical finger sleeve 7. The device is low in cost and hardly damages seedlings, and can be used for automatic transplanting of plug seedlings with different specifications.

Description

technical field [0001] The invention relates to an automatic transplanting device for plug seedlings, in particular to an automatic transplanting device for plug seedlings with two mechanical fingers and four pinching needles. Background technique [0002] Industrial seedling cultivation of vegetables, flowers and other crops is the pioneer of modern agriculture and factory agriculture, and has become the leader of modern vegetable and flower industries. The industrialization of seedlings has great potential for development, and automated seedling raising and transplanting equipment is the key technical equipment for the seedling industry. Plug seedling transplanting technology started earlier in developed countries. Holland has widely used plug seedling automatic transplanting machines (such as Visser Group’s Pic-O-Mat PC series automatic transfer machines, etc.) in greenhouse flower production. Seedlings are automatically transplanted from high-density plugs to low-density...
