Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery, and mainly relates to a horizontal rotary tillage and soil mixing machine for white pulp soil. Background Art

[0002] Albic soil is one of the major low-yield soils in Northeast China. This widespread soil type results in low crop yields. Improving and effectively utilizing this type of soil is crucial for increasing grain production. The soil structure of albic soil is characterized by a 0-20 cm tillage layer, a 20-40 cm albic layer, and a 40-60 cm sedimentation layer. The primary cause of albic soil's low yield is the presence of an obstructive albic layer, characterized by poor physical properties and a hard texture that makes it difficult for crop roots to penetrate.

[0012] The plow frame 1 includes a gantry three-point suspension assembly 101, a traction beam 102, a left mounting beam 103, a bearing mounting beam 104, an oblique beam 105, a right mounting beam 106, a rear cross mounting beam 107, a gearbox mounting frame 108, a left rear mounting beam 109, and a right rear mounting beam 110. One end of the left mounting beam 103 and the right mounting beam 106 is connected to the traction beam 102, and the other end is connected to the rear cross mounting beam 107. One end of the oblique beam 105 is connected to the gantry three-point suspension assembly 101, and the other end is connected to the rear cross mounting beam 107. The bearing mounting beam 104 is installed between the left mounting beam 103 and the right mounting beam 106. The gearbox mounting frame 108 is connected to and installed below the rear cross mounting beam 107. The left rear mounting beam 109 is connected to the left end of the rear cross mounting beam 107, and the right rear mounting beam 110 is connected to the right end of the rear cross mounting beam 107.

[0013] The left tillage layer moldboard plow 2, the left curved surface deep loosening shovel 3, and the left white pulp soil lifting plow 4 are installed on the left mounting beam 103 in sequence starting from the traction end of the plow frame. The left active mixing device 7 is installed on the left side of the rear transverse mounting beam 108. Looking in the direction perpendicular to the ground surface, the plow tips of the left tillage layer moldboard plow 2, the left curved surface deep loosening shovel 3, and the left lifting plow 4 are located on the same straight line. The center position of the left active mixing device 7 is located on the same straight line as the center position of the left lifting plow 4. The right tillage layer moldboard plow 2, the left curved surface deep loosening shovel 3, and the left lifting plow 4 are located on the same straight line. The working layer moldboard plow 10, the right curved deep loosening shovel 11, and the right raised furrow plow 12 are installed in sequence on the right mounting beam 106 starting from the traction end of the plow frame. The right active mixing device 14 is installed on the right side of the rear horizontal mounting beam 107. Looking in the direction perpendicular to the ground surface, the plow tips of the right working layer moldboard plow 10, the right curved deep loosening shovel 11, and the right raised furrow plow 12 are located on the same straight line, and the center position of the right active mixing device 14 is located on the same straight line as the center position of the right raised furrow plow 12.

[0014] The left active mixing device 7 consists of a left transmission mechanism 701, a left horizontal rotary tillage mixing knife 702, and a left retaining plate 703. The right active mixing device 14 consists of a right transmission mechanism 1401, a right horizontal rotary tillage mixing knife 1402, and a right retaining plate 1403. The main transmission shaft 9 is connected to the input end of the gear box 5 through a support bearing 16 installed on the bearing mounting beam 104. The left transmission mechanism 701 is connected to the left output end of the gear box 5 through the left transmission shaft 6. The right transmission mechanism 1401 is connected to the right output end of the gear box 5 through the right transmission shaft 13.

[0015] When in operation, the plow tips of the left and right tillage plows 2 and 10 are positioned near the bottom of the tillage layer, operating at a depth of approximately 0 to 20 cm. The vertical distance between the tips of the left and right curved subsoilers 3 and 11 and the tips of the left and right furrowing plows 2 and 10 is approximately 20 cm, allowing for an operating depth of 20 to 40 cm. The vertical distance between the tips of the left and right raised furrow plows 4 and 12 and the tips of the left and right curved subsoilers 3 and 11 is 10 to 20 cm, allowing for an operating depth of 50 to 60 cm.

[0016] The working principle of the present invention is:

[0017] In working condition, the rear output shaft of the tractor is connected to the main drive shaft 9, and the gantry three-point suspension assembly 101 is connected to the rear suspension of the tractor. When the machine moves forward, the left tillage layer moldboard plow 2 and the right tillage layer moldboard plow 10 respectively plow and move the tillage layer soil to the left and right sides, which will produce a furrow about 20 cm deep and 46 to 60 cm wide. The left curved surface deep loosening shovel 3 and the right curved surface deep loosening shovel 11 are used to deep loosen and break the white pulp layer soil about 20 cm thick to reduce the resistance of subsequent operations. The operating depth of the left lifting plow 4 and the right lifting plow 12 is 50 to 60 cm, which is used to move the white pulp layer soil about 20 cm thick and the sedimentation layer soil about 10 to 20 cm thick in the furrow to the rear and lift it by about 20 cm.

[0018] As the tiller moves forward, the main drive shaft 9 transmits power to the left active mixing device 7 and the right active mixing device 14 through the gear box 5, driving the left horizontal rotary tillage mixing blade 702 and the right horizontal rotary tillage mixing blade 1402 to rotate, breaking up and mixing the white slurry layer and the sedimentary layer soil lifted by the left and right lifting plows 4 and 12. The splashed soil hits the left retaining plate 703 and the right retaining plate 1403 and then falls back into the furrow, thus completing the mixing of the white slurry layer soil and the sedimentary layer soil, greatly reducing the hardness of the white slurry layer soil and significantly enhancing the soil's water permeability and air permeability. The left topsoil backfill plow 8 and the right topsoil backfill plow 15 are used to push the cultivated layer soil that has been moved to the left and right sides by the left and right cultivating layer moldboard plows 2 and 10 back into the furrow, thereby filling the furrow.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
