Mechanical rake for leveling and minifying for broadcast sowing of crop seeds

Abstract

The invention discloses a mechanical rake for leveling and minifying for broadcast sowing of crop seeds. The mechanical rake comprises a fixture block, the fixture block is connected with a supportingframe, the front vertical rod and the rear vertical rod of the supporting frame are vertically connected with fixed sleeves, a rake rod sleeves in every fixed sleeve, end cylinders sleeve the end parts of the rake rods, the end cylinders are fixedly connected to the end sides of side rods, the front end sides of the side rods are connected with a pull rod, the middle of the pull rod is connectedwith a sector plate, the rectangular teeth of the sector plate are in clamp connection with pin teeth, the pin teeth are arranged on a pin rod, the pin rod is sleeved by one adjusting rod, the adjusting rods are vertically connected to the rake rods, and a connecting rod is connected between the adjusting rods. The mechanical rake has the advantages of compact structure, reasonable design, firm structure, long service life, convenience in maintenance, adjustability in the tilting process of the rake teeth, convenience in adjustment of the sinking depth of seeds underground, avoiding of soil from covering the rake rods through the upward warping of the front ends of the side rods, and realization of enhancement of the integral strength of the mechanical rake and avoiding of uneven force induced damages to the mechanical rake at the turning moment of a tractor due to the arrangement of diagonal pull rods.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a mechanical harrow used for sowing and planting agricultural crops and harrowing and harrowing. Background technique [0002] In agricultural production, the planting and cultivation of many crops is carried out through the cultivation and growth of seeds, and in the process of sowing and cultivation, one of the links requires the process of raking the land to facilitate the sinking of seeds. The depth in the land and the nutrition of the seeds are supplied through the soil. However, due to the uneven terrain in mountainous and hilly areas, large-scale agricultural machinery is not suitable for farming and production, and only semi-mechanized agricultural production can be carried out. [0003] Farming and production are carried out by using walking tractors to pull agricultural machinery. Due to the insufficient strength of the current farm implements, the force ...

AI Technical Summary

Problems solved by technology

[0003] Farming and production are carried out by using walking tractors to pull agricultural machinery. Due to the insufficient strength of the current farm implements, the force is uneven when turning, and it is easy to be damaged. Usually, the soil will cover the rake rod and cause the seeds to appear in the process of raking. The soil cannot completely cover the seeds, and the seeds produced cannot be fully utilized. In addition, the land is uneven, which will also cause water accumulation in the land, which is not conducive to the normal growth of crops.
