Device for regulating distances between seedling grippers of rice transplanter

Abstract

The invention discloses a device for regulating distances between seedling grippers of a rice transplanter. The device comprises a seedling gripper main frame and a seedling gripper assembly, the seedling gripper main frame has a substantially reverse U-shaped structure, the seedling gripper assembly is connected between two side boards of the seedling gripper main frame through a gripper lockingcylinder, the gripper locking cylinder runs through base boards of the seedling gripper assembly, fixed seedling grippers and movable seedling grippers are symmetrically arranged on the seedling gripper assembly, positions, located at two sides of each base board, of the gripper locking cylinder are separately and symmetrically provided with a limit sleeve ring in a sleeving manner, a protective rubber flap is installed on each corresponding inner side surface of the fixed seedling grippers and the movable seedling grippers, the top end of each fixed seedling gripper is provided with a north pole of a magnet, and the top end of each movable seedling gripper corresponding to the top end of one corresponding fixed seedling gripper is provided with a south pole of a magnet, each fixed seedling gripper is fixedly installed on one end of the outer surface of one base board through a flange board, the bottom end of each movable seedling stripper is connected with an embedded sleeve plate through a hinge, each embedded sleeve plate is connected with one corresponding base board, and each flange board is connected with one corresponding embedded sleeve plate through a threaded distance column, thus people can regulate the distances between the seedling grippers conveniently.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a seedling claw spacing adjustment device of a rice transplanter. Background technique [0002] Among agricultural machinery, the rice transplanter is a common agricultural machinery that implants rice seedlings into the rice field. When planting, first use mechanical claws to take out several rice seedlings from the seedbed and plant them into the soil in the field. In order to keep the angle between the seedbed and the ground at a right angle, the tip of the mechanical claw must adopt an elliptical motion curve when moving. The action is completed by the planetary mechanism of rotating or deforming gears, and the advancing engine can drive these action machines at the same time. The rice transplanter must have anti-slip wheels and floating design when running on the soil. If the seedlings are planted into slices, the rice seedlings are taken out of a specific seedli...

AI Technical Summary

Problems solved by technology

[0003] (1) The distance between the seedling claws in the general rice transplanter is not adjustable, so for some hybrid rice with different requirements, it is not easy to separate the seedlings for uniform installation requirements, or cause a series of uneven separation of seedlings such as root and stem tearing problems, but also affect ventilation and light transmittance and other issues;

[0004] (2) The seedling claws in general rice transplanters cannot adjust the row spacing of rice transplanting according to the requirements of rice planting density, so as to realize the transplanting of rice in wide and narrow rows, thereby reducing the yield per unit area of ​​rice and reducing the applicability of rice transplanter
