Scraping shovel type trench opener and scraping shovel type ditching fertilizer spreader

Abstract

The invention discloses a scraping shovel type trench opener and a scraping shovel type trenching fertilizer applicator. The scraping shovel type trench opener comprises a connected trenching shovel and a shovel handle, and the outer movable sleeve of the shovel handle is provided with a back-shaped blade , the back of the back-shaped blade is connected with the driving mechanism through the transmission mechanism; the shovel handle and the ditching shovel are provided with a fertilizer output channel that communicates with each other, and the back of the ditching shovel is provided with a fertilizer drop channel that communicates with the fertilizer output channel. mouth. The fertilizer spreader of the present invention includes a frame on which a plurality of the scraping shovel openers are symmetrically and evenly arranged, and a fertilizer box is also arranged on the frame, and the fertilizer box is connected with the fertilizer discharger and the pipeline. The shovel handle is connected with the fertilizer channel. The invention has the advantages of simple structure, automatic removal of weeds, entanglement of straws and clay, low resistance, low energy consumption, high operation efficiency and long service life of equipment, and is especially suitable for rice stubble and wheat sowing operations in high-viscosity soil.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a scraping shovel type trench opener and a scraping shovel type trenching fertiliser. Background technique [0002] Straw mulching and return-to-field conservation tillage is an advanced farming technology that uses crop straw to cover the surface and implements no-tillage and less tillage on farmland. The paddy fields in the agricultural areas of the middle and lower reaches of the Yangtze River are mostly viscous soils, and with high moisture content, the soils are easily adhered. After mechanical harvesting of rice, rice stubble has the characteristics of large coverage, high stubble remaining, and high shear strength, resulting in easy entanglement of rice stubble. Therefore, how to realize the high-efficiency anti-tangle and sticking of the opener under the conditions of rice stubble and wheat sowing in the flood-dry rotation area and improve the quality of no-tillage ...

AI Technical Summary

Problems solved by technology

Although the opener anti-blocking device can alleviate the problem of straw blockage near the opener to a large extent, it cannot handle the clay adhering to the opener well, which increases the power consumption of the opener. It is suitable for Ditching operations in dry fields are not suitable for ditching operations in rice stubble fields

[0004] On the other hand, people also hope to install the ditch opener on the fertilizer applicator to realize the integrated setting of ditching and fertilization. For example, 201910589534.5 discloses a ditching fertilization and soil covering device for a rice seedling transplanting synchronous fertilization machine. On the support wall 5 at the rear, the purpose of fertilizing while ditching is realized. Although this structure increases the function of the fertilizer applicator, it does not solve the problems of ditch blockage and clay adhesion. Not only that, because the fertilization pipe needs to be arranged in the Near the back of the opener, there are many local components, and the fertilization pipe and the opener are more likely to be blocked, which requires regular manual treatment and is not easy to clean, which greatly affects the operation efficiency
