Movable plant clamping and fixing device with automatically-separable clamping jaws

Abstract

The invention relates to a movable plant clamping and fixing device with automatically-separable clamping jaws. The movable plant clamping and fixing device comprises a base, a multi-jaw chuck clamping device, a sleeve, auxiliary fixing legs and handles. The multi-jaw chuck clamping device comprises an annular chuck wire coil and a plurality of elastic clamping jaw devices. The sleeve consists of a hollow cylinder and conical barrel at the lower end of the hollow cylinder, the multi-jaw chuck clamping device is mounted on the base, the center of the base is provided with a first through hole identical to the sleeve in internal diameter, and the elastic clamping jaw devices are capable of simultaneously moving towards or away from the axis of the first through hole to tightly clamp or release crop stalks in the sleeve. The movable plant clamping and fixing device is simple in structure, small in size, portable and capable of clamping stalks different in thickness and freely moving by a fixed distance according to requirements to adjust row spacing and line spacing, and simulation of various field planting modes such as broadcast sowing, transplanting and mechanical sowing of crops can be realized.

Description

Technical field [0001] The invention relates to an auxiliary device for agriculture, in particular to a movable plant clamping and fixing device with a claw that can be automatically separated. Background technique [0002] Existing plant plant holding devices that simulate field harvesting are mainly transverse conveyor devices. Divided into fixed type and mobile type, fixed type transverse conveyor, fixed type transverse conveyor, the main working part is a hollow tubular device, the disadvantage is that a fixed aperture can only support a fixed diameter of the plant stem, and the stability is not Good, the effect of tightening the straw is not stable, and it is not easy to take out the straw when it is broken. The disadvantage of the mobile transverse conveyor is that it cannot simulate the misalignment of crops, the blessing radius of the blessing part is fixed and cannot be changed, and the cost is high. Three-jaw chucks are used in the existing mechanical fields, but afte...

AI Technical Summary

Problems solved by technology

It is divided into fixed type and mobile type, fixed type horizontal conveyor, fixed type horizontal conveyor, the main working part is a hollow tubular device, the disadvantage is that a fixed aperture can only support plant stems with a fixed diameter, and the stability is not good Well, the tightening effect on the straw is unstable, and the straw is not easy to take out when it is broken

The disadvantage of the mobile horizontal conveyor is that it cannot simulate the uneven distribution of crops, the radius of the holding part is fixed and cannot be changed, and the cost is high

Some of the existing mechanical fields use three-jaw chucks, but after the existing chucks are used up, when the jaws are loosened, it is necessary to re-twist the bevel gear, slowly rotate the coil wire, and adjust the jaws. The jaws cannot be separated automatically. , inconvenient to use
