Wide traction type dry farmland levelling apparatus

Abstract

The invention discloses wide traction type dry farmland levelling apparatus. The apparatus comprises a traction device, a vehicle frame, a lifting hydraulic cylinder component and a soil shovelling working device; the soil shovelling working device is composed of a traction frame, a rotary mechanism, a revolving ring, an angular displacement device, a scraping shovel and a plurality of hydraulic cylinders, and is the main working part of the levelling apparatus. According to the levelling apparatus, the traction force and hydraulic power sources are provided by a traction vehicle (such as a tractor), six forms of movements of the scraping shovel can be realized, that is, scraping shovel lifting, scraping shovel swinging, scraping shovel side extension, scraping shovel angle change, scraping shovel rotation, and scraping shovel soil shovelling translation at the front and the back. The manner that the traction vehicle is additionally joined to the levelling apparatus is adopted, so thatthe levelling function in various dry farmland can be realized, the large-area land levelling effects are good, and the working efficiency is high.

Description

Technical field [0001] The invention relates to the field of agricultural machinery, in particular to a wide traction type dryland leveling device. Background technique [0002] The leveling of farmland has an important impact on the quality and efficiency of agricultural irrigation. After the land is leveled, it can increase crop yields, save irrigation water, increase land utilization, and reduce the use of pesticides and fertilizers. With the continuous improvement of my country's agricultural mechanization, leveling machines will be more and more used in farmland land leveling, and the working efficiency and accuracy of leveling machines will largely affect agricultural production costs and crop yields. [0003] At present, farmland leveling machines mostly use draped or single-bridge traction leveling devices. Single-bridge leveling devices have poor working stability and large leveling errors. The draped shovel depth is shallow and the work efficiency is low. For the levelin...

AI Technical Summary

Problems solved by technology

[0004] The soil hardness of dry fields varies from place to place. For soil with low hardness, a larger shovel area can be used for leveling; but for soil with higher hardness, the width of shovel should not be too large, otherwise the resistance of the leveling device will be too large. May affect leveling accuracy

In some narrow and long land, it will not be leveled because the scraper is too long, so the width of the shovel needs to be adjusted

[0005] There may be obstacles such as large stones in the dry field, and the shape of the edge of the field may also be irregular. It is difficult to reach these areas with a spatula, and it needs to be done manually, which greatly affects the efficiency.
