Soybean double-row drilling boot

Abstract

The invention relates to a soybean double-row drilling boot belonging to the agricultural machinery. A left side plate and a right side plate are assembled on the lower end part of a grain tube in a regular trapezoid and oppositely incline way. The acute boot is assembled on the end parts of the front sides of the left side plate and the right side plate, a baffle plate is fixedly arranged in a grain tube cavity, the inner cavity of the grain tube is divided into a front grain cavity and a rear grain cavity, the front grain cavity is communicated and matched with the inner side of the left side plate or the right side plate, and the rear grain cavity is communicated and matched with the inner side of the right side plate or the left side plate. The boot has simple and compact structure, little operation resistance, less booting ground-breaking quantity, high operation precision of the double-row drilling and reliable use, and is beneficial to the soil moisture.

Description

Technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a soybean double sowing ditching assembly. Background technique [0002] The core-shaft opener is a widely used opener in dry field planting operations in Northeast my country. Because of its simple structure, flat bottom of the seed furrow, and low cost, it has been used until now. However, the two side plates of the core-shaft opener are arranged vertically and parallel as a whole, and the opener has a rectangular cross-section. Not only does it have a large resistance during operation, but also has a large amount of soil, which is not conducive to the preservation of soil moisture, especially The use is restricted in the northeastern region of the ten-year drought. In recent years, the agronomic method of double sowing on soybean ridges has been widely promoted and applied. In order to meet the requirements of two soybean sowing operations, two conveying pipes are used to connect the...

Problems solved by technology

However, the two side plates of the coreshare type ditch opener are arranged vertically and parallel as a whole, and the cross section of the ditch opener is a rectangular structure. During operation, not only the resistance is relatively large, but also the amount of soil movement is large, which is not conducive to the preservation of soil moisture. Use is limited in the Northeast where there is nine spring droughts in ten years

In recent years, the agronomic method of double-row sowing on soybean ridges has been popularized and applied on a large scale. In order to meet the requirements of two soybean sowing operations, two conveying pipes are used to connect the fertilizer discharger and the coreshare type ditch opener, and the structure is complicated. It is inconvenient to configure and install, and the accuracy of two-row sowing operation is not easy to guarantee
