Abstract

A double-row-tooth non-handle grain harrow for tedding grains comprises a frame body 1, front row harrow teeth 2 fixedly connected to the front side surface of the frame body 1 at preset intervals, rear row harrow teeth 2 fixedly connected to the rear side surface of the frame body 1 at preset intervals, and pull ropes 3 connected to the frame body 1, wherein the front row harrow teeth 2 and the rear row harrow teeth 2 are staggered with each other. The grain raking device can be used for turning over the grain for the second time, and can pull a plurality of grain rakes to advance side by side at the same time, so that the rake teeth of each grain rake can be better attached to the ground, the operation width of each grain rake can be increased by multiple times, and the grain can be prevented from being diffused to the edge of a grain sunning field in each grain turning operation; when the grains are sunned on the rural roads, the electric car is very suitable for being pulled by the electric car.

Description

Double-row-tooth non-handle grain rake for grain tedding

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a double-row tooth no-handle grain harrow for grain tedding.

Background

After the grains are harvested, the grains need to be exposed to the sun, the moisture is dried in the sun, and then the grains can be stored, otherwise the grains are easy to mildew and deteriorate. Due to the limitation of the conditions such as the field and the like, the grains are generally dried thickly, so that the grains need to be repeatedly turned up and down in the insolation process. The traditional grain harrow only has one row of harrow teeth, and gaps which are not less than the width of the harrow teeth are required to be reserved between the adjacent harrow teeth, so that half of bottom grains in one-time harrow turning are not turned, the grains need to be harrow back and forth at the same position to achieve the effect, and the working efficiency is low. The rake head of the traditional rake can not be too wide, on one hand, the rake head is too wide and is not easy to control and push, on the other hand, the wider the rake head, the poorer the fit degree between the rake teeth and the ground, the more the bottom grain of the rake is, and the further the working efficiency is limited. Along with the perfection of rural highway networks and the gradual popularization of mechanical harvesting, rural highways become the most main grain sunning places, and if the grain tedding process is completed by providing the grain harrow which can be directly pulled by the electric vehicle, the working efficiency is further improved, the labor intensity is reduced, and the pressure of the high-temperature insolation working environment on human bodies is greatly relieved.

Disclosure of Invention

Therefore, the utility model aims to provide a double-row tooth no-handle grain harrow for grain tedding, which adopts the pull rope for pulling, has simple and durable structure, can turn grains for the second time in one-time pulling, can adopt the electric vehicle for driving, greatly improves the working efficiency and reduces the labor intensity; the utility model discloses a another purpose can stimulate two or a plurality of mutually independent millet harrows simultaneously and advance side by side, promotes the operation width several times when guaranteeing the operation quality to further promote work efficiency several times.

The utility model provides a double row tooth does not have handle millet harrow for cereal tedding, it includes a framework 1, according to predetermined interval rigid coupling in front row rake teeth 2 on the framework 1 leading flank, according to predetermined interval rigid coupling in back row rake teeth 2 on the framework 1 trailing flank and connect be in stay cord 3 on the framework 1, front row rake teeth 2 with back row rake teeth 2 stagger each other.

Furthermore, an operation combination is formed by two or more double-row-tooth non-handle grain rakes for grain tedding, the two or more double-row-tooth non-handle grain rakes for grain tedding in the operation combination are mutually independent and are arranged side by side, and the right part of the rightmost rake tooth 2 of the double-row-tooth non-handle grain rakes for grain tedding in the operation combination extends towards the right front to form a blocking edge 2 a; therefore, two or more double-row-tooth non-handle grain rakes for grain tedding can be pulled to advance side by side in the operation combination, the two or more double-row-tooth non-handle grain rakes for grain tedding can simultaneously perform raking operation during advancing, and the blocking edge 2a can prevent right grains from spreading to the right side.

In order to further improve the performance, the rake teeth 2 are made of spring pieces.

The utility model provides a beneficial effect that technical scheme brought is: when the frame body 1 and the rake teeth 2 thereof are pulled to advance through the pull rope 3, the front row of rake teeth 2 turn over grains, and then the rear row of rake teeth 2 turn over the bottom-layer grains which are not turned over by the front row of rake teeth 2 again, so that the effect can be doubled; the multi-purpose grain harrow can simultaneously pull a plurality of grain harrows to advance side by side, the operation width and the effect of the multi-purpose grain harrow can be improved by multiple times, and the harrow teeth 2 of each grain harrow can be well attached to the ground due to the mutual independence of the grain harrows, so that the operation quality can be ensured while the effect is improved; the rake tooth blocking edge 2a on the right side can prevent the grains from diffusing to the edge of the grain sunning field in each grain overturning operation; because of the country highway has become the leading grain farm of shining most, and the embodiment of the utility model provides a technical scheme is very suitable for adopting the electric motor car pulling, and this will promote work efficiency, reduce intensity of labour further to greatly alleviate the pressure that the harrow millet environment that high temperature insolate brought the human body.
