Description

Technical Field

[0001] The utility model relates to the technical field of paddy field leveling, and more specifically, to a paddy field leveling machine. Background Art

[0002] With the continuous development of the economy, agricultural production has entered the era of automation. A large number of automated agricultural equipment have been developed and put into use, greatly improving agricultural productivity and bringing great convenience to farmers. A paddy field leveling machine is a mechanical device used to level paddy fields. It is usually used in conjunction with a tractor. After the paddy field is rotary tilled, it levels the paddy field, so as to save irrigation water, avoid uneven growth of rice during growth, affect the per mu yield, and is also beneficial to subsequent transplanting operations.

[0003] In the traditional process of paddy field finishing, a flat scraper with broken teeth is mainly used to level the paddy field. At the same time, limited by the length of the scraper, the efficiency is low. At the same time, in response to paddy fields with different depths, large-scale and standardized leveling cannot be carried out, which is not conducive to the normal operation of subsequent agricultural processes.

[0004] Chinese Patent with the application number CN202322184574.6 discloses a portable paddy field leveling machine, which includes a leveling plate, a folding mechanism, an adjusting mechanism, an adaptive leveling mechanism, a lifting mechanism and a power device. After the operator spreads the leveling plate flat by using the folding mechanism, adjusts the working angle through the adjusting mechanism and the lifting mechanism, and then levels the paddy field by pulling of the power device. At the same time, the adaptive leveling mechanism can effectively solve the influence of different depths on the equipment. The equipment has a simple structure, effectively increases the operation area, and also adapts to the working scenarios of leveling with different depths and subsequent transportation scenarios, which is beneficial to the promotion and use of the product.

[0005] However, it can be seen from its specification drawings that when leveling the paddy field, only the leveling plate with a large inclination amplitude moves on the surface of the paddy field for leveling. When there are some positions with deep depressions or large protrusions, it will cause the leveling plate to move up and down, and it is impossible to effectively scrape away the soil at the protrusion position and move it into the depression, thus affecting the leveling effect and efficiency.
