Abstract

The invention relates to a device for measuring the clamping force of a planting apparatus by utilizing a photoresistor. The device is arranged between a first clamping claw and a second clamping claw of the planting apparatus, the device consists of an outer sleeve and an inner sleeve, the first clamping claw is connected with one end of the outer sleeve through a first universal joint in a rotating manner, and the second clamping claw is connected with one end of the inner sleeve through a second universal joint in a rotating manner; a through hole is formed in one end, of the outer sleeve, facing towards the second clamping claw, and a light source array and a visor are arranged in the through hole vertically, wherein the light source array comprises a plurality of optical fiber light sources which are arranged side by side along the axial direction of the outer sleeve, and the visor comprises a plurality of sun shading areas which correspond to the optical fiber light sources one by one; and a light hole is formed in one end, arranged in the outer sleeve in a sliding manner, of the inner sleeve, and a photoresistor is arranged in the inner sleeve. A spring is used as a force device for detecting the clamping force, and the precise measurement on the deformation quantity of the spring can be realized by matching the light sources with the photoresistor, so that the clamping force can be precisely calculated according to the mechanical properties of the spring.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a device for measuring the clamping force of a planter by using a photoresistor. Background technique [0002] The core of the automatic fetching and feeding system for plug seedling transplanting is the seedling picking manipulator, which mainly completes the removal and transfer of plug seedlings from the plug tray. Seedling picking claws are the smallest functional unit of the seedling picking manipulator. Each seedling picking claw is like a seedling picking hand in the manual transplanting process, completing the actions of picking and putting seedlings. Through the analysis of each link of manual seedling picking, the various actions of human hands are replaced by the seedling picking device, and automatic seedling picking can be realized. The typical process of picking seedlings manually is: pairing holes → picking seedlings → holding seedlings → transferring → feedi...
