Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology and relates to a brittle and hard root and straw crushing device that combines soil spraying and air explosion crushing. Background Technology

[0002] In northern regions, a large amount of brittle and hard root stalks remain in the fields after crop harvest. Existing machinery mostly uses rotary tillage or cutting to deal with these stalks. However, the blades wear out easily and have poor crushing effect on the root stalks, resulting in significant soil disturbance and severe moisture loss. This affects the decomposition of the root stalks and the quality of subsequent sowing, making it difficult to meet the needs of modern precision agricultural production. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical problems by developing a soil jetting and air-blasting crushing device for brittle and hard stubble. A star-shaped discharge valve intermittently diverts the crushed soil from the soil storage tank to the air-solid jetting device. Taking advantage of the equidistant characteristics of mechanized planting, the device launches targeted air jets at specific corn plants as it moves, achieving precise crushing of brittle and hard stubble and straw. A reciprocating mechanism using an eccentric wheel-roller and a pulse-jet high-pressure gas system from an air compressor enables precise air-blasting of the root system. Using negative pressure from a blower, the air-blasted soil is drawn into the storage tank through a ring-shaped suction cylinder. Subsequently, the soil jetting device precisely sprays soil particles to crush the brittle and hard stubble and straw.

The pneumatic root-breaking and soil-absorbing device uses an eccentric wheel-roller direct-drive reciprocating mechanism to drive the soil-breaking probe and the annular soil-absorbing cylinder to move up and down in a reciprocating motion. While breaking the soil up and down, the air compressor intermittently injects high-pressure gas to penetrate deep underground and break the root system. Then, a blower sucks the broken soil into the storage tank, avoiding large-scale soil disturbance and effectively conserving soil moisture. Attached Figure Description

[0019] During operation, the soil-launching stubble-breaking device first crushes the stubble and straw, followed by the air-blasting soil-suction root-breaking device that penetrates deep into the ground to blast and break the root system. The specific transmission is as follows: the tractor drives the implement forward through the three-point suspension frame 1; the second battery 12 in the soil-launching stubble-breaking device powers the second motor 13; the first controller 11 controls the intermittent start and stop of the star-shaped unloading valve 9; the second motor 13 controls the impeller 25 in the star-shaped unloading valve 9 to rotate, causing the soil in the soil storage tank 4 to fall through the diverter pipe 24 into the first air-solid ejector 17 and the second air-solid ejector 20; the seventh battery 47 powers the first air compressor 16; the eighth battery 48 powers the second air compressor 21; the third battery 14 powers the second controller 15; and the fourth battery 23 powers the third controller 22.

High-speed soil particles, like "shotgun shells," strike the remaining brittle and hard straw on the ground, completely crushing it. The motor 42 in the air-blast soil-absorbing root-breaking device rotates, driving the eccentric wheel 40 to rotate via the transmission shaft 49. The annular suction cylinder 36 is limited by the fixed rod 31 and spring 32 to ensure its reciprocating motion. The spring 32 keeps the eccentric wheel 40 and roller 33 in close contact. The eccentric wheel 40 drives the roller 33, causing the soil-breaking probe 38 and the annular suction cylinder 36 to periodically insert into the soil. When reaching the extreme downward position, the fourth controller 28 controls the third air compressor 44 to pulse-jet high-pressure gas through the jet nozzle 37, instantly crushing the brittle and hard roots underground using the air-blast principle. The first battery 5 powers the blower 8, creating negative pressure in the second hose 46, sucking the crushed soil into the soil storage tank 4. This cycle repeats, achieving the air-blast crushing of brittle and hard roots and straw.
