Description

Technical Field

[0001] This utility model belongs to agricultural machinery, and mainly relates to a combined operation machine for applying base fertilizer before sowing and weeding, breaking up soil and preparing the land on ridges and seedbeds. Background Technology

[0002] To improve seed germination rates and ensure crop growth quality, dryland agriculture in Heilongjiang and Jilin provinces of Northeast my country often employs a method of applying basal fertilizer to the seedbed soil before sowing, followed by sowing using a single-operation seeder. However, years of practical experience have revealed that current pre-sowing fertilization equipment only performs fertilization and lacks the mechanisms and functions to simultaneously weed, break up soil, and prepare the seedbed after fertilization. This results in poor seedbed quality after pre-sowing fertilization, with issues such as uneven soil texture, insufficient weed growth, and residual weeds, severely impacting and reducing the quality and effectiveness of sowing after pre-sowing fertilization. Summary of the Invention

[0003] The purpose of this utility model is to address the problems existing in the prior art and, in combination with the actual needs of current mechanized pre-sowing fertilization operations, to develop and design an integrated machine for pre-sowing fertilization and ridge weeding and soil pulverization, so as to achieve the combined operation of pre-sowing fertilization and ridge weeding and soil pulverization, high operation efficiency, fine and level seedbed soil, good weeding effect, and provide high-quality seedbed conditions for sowing operations.

[0004] The basic design of the utility model is as follows: a seat plate frame is fixed on the lower side of the frame assembly, between the rear sides of two relatively arranged wheel frames. A roller frame is hinged on the seat plate frame and can swing up and down via pin B. A tillage and weeding toothed roller is rotatably supported on the rear end of the roller frame. The tillage and weeding toothed roller is located on the rear side of the double disc furrow opener assembly, and the lowest point of the double disc furrow opener assembly is lower than the lowest point of the tillage and weeding toothed roller. This constitutes an integrated machine for pre-sowing fertilization, ridge weeding, soil breaking and land preparation.

[0005] This utility model innovatively combines a pre-sowing fertilization mechanism with a mechanical inter-row cultivation and weeding mechanism on the same machine, realizing a combined and integrated operation of pre-sowing fertilization and ridge weeding and soil breaking. It completely overcomes and solves the technical problems of existing single pre-sowing fertilization machines. It features a novel and unique structure, high operating efficiency, and finely broken and leveled seedbed soil and good weeding effect after pre-sowing fertilization, providing a high-quality seedbed for subsequent sowing operations.

[0009] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0010] A machine integrating pre-sowing fertilization, ridge weeding, soil breaking, and land preparation includes a frame assembly 1 and a toothed disc roller 3 for inter-row weeding. A three-point suspension mechanism 13 is fixedly mounted on the upper front side of the frame assembly 1. Ground wheel assemblies 9 are rotatably mounted on the lower left and right ends of the front side of the frame assembly 1 via wheel frames 12. A fertilizer box 14 equipped with a fertilizer applicator 15 is mounted on the upper end of the frame assembly 1. A vertically adjustable hanging frame 11 is mounted on the lower middle part of the front side of the frame assembly 1. A double disc furrow opener assembly 7 is hinged to the lower end of the hanging frame 11 via a pin A8, allowing it to swing vertically. A fertilizer delivery pipe 16 connects the fertilizer applicator 15 and the double disc furrow opener assembly 7. A contour pressure spring 10 is installed between the hanging frame 11 and the double disc furrow opener assembly 7. A seat plate frame 6 is fixed on the lower side of the frame assembly 1, between the rear sides of the two opposing wheel frames 12. A roller frame 4 is hinged on the seat plate frame 6 via a pin B5, allowing it to swing up and down. A tillage and weeding toothed roller 3 is rotatably supported on the rear end of the roller frame 4. The tillage and weeding toothed roller 3 is located on the rear side of the double disc furrow opener assembly 7, and the lowest point of the double disc furrow opener assembly 7 is lower than the lowest point of the tillage and weeding toothed roller 3. A hanging tension spring 2 is connected and installed between the rear side of the frame assembly 1 and the roller frame 4.

[0011] During operation, the machine is suspended and connected to the rear of the tractor by the three-point suspension mechanism 13 and moves forward. The ground wheel assembly 9 rolls in support contact with the ground. The lower parts of the double disc ditcher assembly 7 and the weeding toothed roller 3 are inserted into the soil and rotate under the action of soil resistance. They sequentially complete the ditching operation and the weeding, breaking up and leveling operation of the seedbed soil. Since the lowest point of the double disc ditcher assembly 7 is lower than the lowest point of the weeding toothed roller 3, the ditch is deep. At the same time, the fertilizer discharge device 15 discharges the fertilizer in the fertilizer box 14 into the ditch through the fertilizer pipe 16. Under the control of the pin A8, the contour pressure spring 10 realizes the up and down swing of the double disc ditcher assembly 7 on the hanging frame 11 to complete the contour movement and ensure the consistency of the ditch depth. The rotation of the roller frame 4 around the pin B5 on the seat frame 6 causes the weeding and cultivating toothed roller 3 to move up and down with the ground, ensuring the effectiveness of weeding, soil breaking, and leveling operations. When the machine is in suspended transport mode, the suspension tension spring 2 can be used to limit the lowest position of the weeding and cultivating toothed roller 3 through the roller frame 4, ensuring transport safety.
