Two-needle clamping mechanism for dry farmland in-bowl rice seedling transplanting

Abstract

The invention discloses a two-needle clamping mechanism for dry farmland in-bowl rice seedling transplanting, and belongs to agricultural machinery. A stem casing, a left needle guard and a right needle guard are mounted on a triangular platy frame; the axes of the stem casing, the left needle guard and the right needle guard are located on the same plane; the axis of the left needle guard and the axis of the right needle guard are integrally intercrossed to be V-shaped; a driving rod is inserted into the stem casing; a left inclined rod and a right inclined rod are symmetrically fixed at the lower end part of the driving rod and sleeved by a left sliding sleeve and a right sliding sleeve respectively; a left rice seedling needle and a right rice seedling needle are inserted into the left needle sleeve and the right sliding sleeve respectively; the left rice seedling needle is connected with a left sliding sleeve hinge, and the right rice seedling needle is connected with a right sliding sleeve hinge. When the device is used for clamping the rice seedling bowl, the left rice seedling needle and the right rice seedling needle linearly reciprocate along a fixed angle, and the left rice seedling needle and the right rice seedling needle are directly inserted into the bowl without damage to soil, in-bowl rice seedling and root system, so that the two-needle clamping mechanism can efficiently, accurately and reliably grasp the rice seedling in the bowl, and has the characteristics of reasonable structure, simplicity, good operation quality, high efficiency, less fault and wide application.

Description

technical field [0001] The invention belongs to agricultural machinery, and in particular relates to a pot seedling picking device for transplanting pot seedlings in dry fields without damaging the root system. Background technique [0002] At present, there are mainly two types of clamping mechanisms for pot seedling transplanting machines in dry fields: one is a bowl-taking clip for clamping the pot body; the other is composed of multiple rods (more than 3), multiple hinges, and multiple Bowl fetching device composed of slideways. The first type of bowl-taking clip is made of rigid material with better elasticity. The clip has a certain inclination angle. The clip is clamped and loosened during the reciprocating movement of the U-shaped slider. When clamping, the bowl is taken and loosened. When pushing the bowl, the problem of this mechanism is: after the clip penetrates into the soil, the shape of the soil will be damaged to some extent; at the same time, the clip cuts ...

AI Technical Summary

Problems solved by technology

The first type of bowl-taking clip is made of rigid material with better elasticity. The clip has a certain inclination angle. The clip is clamped and loosened during the reciprocating movement of the U-shaped slider. When clamping, the bowl is taken and loosened. When pushing the bowl, the problem of this mechanism is: after the clip penetrates into the soil, the shape of the soil will be damaged to some extent; at the same time, the clip cuts off the root system when it penetrates into the soil, which affects the planting quality; After a period of time, the elasticity of the clips decreases or the clips break, resulting in the inability to effectively complete the transplant

The problems of this mechanism are: due to too many rods and hinges, the structure is complex, the failure rate is high, especially it can only work at low speed, the work efficiency is low, and it is not suitable for field work in harsh working environment
