Mechanical ditching and soil covering device used in rice stubble paddy fields

Abstract

The invention provides a mechanical ditching and soil covering device used in rice stubble paddy fields. The device is characterized by mainly comprising a towing bracket, a ditching plow, a balance tail wheel and directional soil covering plates, wherein the main body of the towing bracket is a horizontal cross bracket which is formed by connection of a longitudinal beam and a cross beam; a towing connector is arranged at the front end of the longitudinal beam and can be connected with various tractors to play a role of towing; the ditching plow is connected below the middle part of the longitudinal beam and plays roles of ditching and left and right bidirectional soil distributing; the balance tail wheel is connected below the rear end of the longitudinal beam, can be elastically adjusted up and down and plays roles of adjusting ditch depth, planishing ditch bottom and balancing integral stress; and the directional soil covering plates are respectively connected below the two ends of the cross beam and play a role of directionally stacking furrow slices at controlled intervals. The device is especially suitable for plow-type ditching in the rice stubble paddy fields before rape transplanting.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a mechanized ditching and soil covering device for rice stubble fields. Background technique [0002] The winter rapeseed production belt in the Yangtze River Basin is the main rapeseed production area in my country, with late rice stubble rapeseed as the main planting mode. However, due to the high-yielding rapeseed planting in the Yangtze River Basin, intensive cultivation has been adopted for a long time, and seedling cultivation and transplanting, ditching, fertilizer and water management and harvesting are mainly performed manually. In recent years, due to the irreversible trend of labor shortage in rural areas and rising activation costs, the traditional production method that employs a large amount of labor has become the most important limiting factor for the development of rapeseed production in this area. Cultivation machinery. Therefore, the "Opinion...

AI Technical Summary

Problems solved by technology

At present, due to the heavy rainfall in the winter rapeseed production areas in southern my country, the rapeseed fields must adopt ditch drainage measures to reduce waterlogging in order to be conducive to high yields. In production, due to the high soil moisture in the rice paddy field and the rainy late autumn, it is suitable for rotary tillage before transplanting rapeseed. The probability of ditching is low. In order to strive for the season to achieve early autumn and winter emergence of rapeseed, farmers often carry out artificial ditching after transplanting rapeseed. The timeliness of ditching and drainage is poor, and the labor intensity of ditching is high, and the quality of ditch shape is not ideal.
