Double-row subsoiler

Abstract

The invention discloses a double-row subsoiler, comprising a rack, a traction frame installed on the rack, a plurality of sub-soiling shovels which are installed on the rack and are arranged in two rows, and road wheels installed on two ends of the rack. The number of the sub-soiling shovels is seven, and the sub-soiling shovels are uniformly arranged at interval on the rack in a front-three rear-four manner. The shovel shaft of the sub-soiling shovel is provided with a plurality of holes, and the shovel shaft is fixed with the rack through U-shaped set bolts. A swallow-tail form soil loosening plate is arranged on a shovel head. The road wheels are arranged on the front part of the rack. A connecting rod of the rack is provided with a plurality of holes, and height adjustment is realized through using the set bolts on the holes of the rack. Through arranging two rows of the sub-soiling shovels and arranging the swallow-tail form soil loosening plate on the shovel head, so deep scarification effect is obvious, deep scarification depth is uniform without dead angle. The double-row subsoiler satisfies requirements of crops, solves soil deep hardening, improves soil water storage capability, and soil moisture conservation and fertilizer maintenance performance, and improves capability of crops to absorb water and nutrient.

Description

technical field [0001] The invention relates to a double-row subsoiler, which belongs to the technical field of agricultural machinery. Background technique [0002] The subsoiler is a kind of agricultural farming machinery. In recent years, there have been many disadvantages in the use of rotary tillers, such as the depth of soil preparation is between 10-20cm, which cannot reach the bottom of the plow, resulting in partial soil compaction, or after rotary tillage. Immediately start planting, the soil cannot be restored, resulting in shallower roots for crop growth, underdeveloped root system, seriously affected water and nutrient absorption, low yield, poor quality, and reduced benefits. [0003] The subsoiler solves the problem of deep soil compaction, improves the performance of soil water storage, moisture conservation, and fertilizer retention, which is conducive to the growth of crops, agricultural production, and farmers' income. However, the existing subsoiler struc...

Problems solved by technology

There is a technical contradiction in this structure. If the spacing between the subsoiling shovels is too large, the subsoiling effect of the soil will be poor, resulting in inconsistent subsoiling effects at the place where the shovel enters and the surrounding area, and adjusting the spacing of the shovels or changing the size of the shovel head will cause excessive traction power. Problems with large or insufficient subsoiling depth
