Description

Technical Field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to a full-row-spacing strip tillage machine and a method for realizing full-row-spacing sowing. Background Art

[0002] In recent years, the area of ​​corn cultivation using conservation tillage technology in my country has gradually increased, and straw-row strip tillage technology has also been continuously accepted by farmers. However, straw-row strip tillage technology still has shortcomings. The ridge spacing adjustment of the strip tillage machine is limited and cannot meet all ridge spacing requirements. Farmers have many types of ridge spacing, which also limits the operation of the strip tillage machine. The present invention uses two small strip tillage belts with a small leisure belt in the middle to replace the large strip tillage belts and large leisure belts of the traditional strip tillage machine, so that farmers can find the corresponding sowing position on the strip tillage belt with a ridge spacing of 400 to 700. This flexibly solves the problem of inconsistent ridge spacing and difficulty in sowing among farmers, laying the foundation for the widespread promotion of strip tillage conservation tillage. Summary of the Invention

[0003] The purpose of the present invention is to address the deficiencies in the existing technology and provide a full-row spacing strip tillage machine and a method for achieving full-row spacing sowing. Through the machine and method of the present invention, full-row spacing strip tillage operations can be achieved, and on this basis, full-ridge spacing sowing operations can be achieved. This solves the problem of farmers' different ridge spacing and operational difficulties, making wide and narrow row conservation tillage more operational.

[0004] To achieve the above objectives, the present invention provides a full-row spacing strip tillage machine and a method for achieving full-row spacing sowing, a full-row spacing strip tillage machine comprising: a frame, a deep loosening shovel, a deep loosening shovel seat, a lower suspension, a weeding wheel, an adjustment ground wheel, an upper suspension, a main gear box, an oil tank, a radiator, a pressure roller transmission box, a hydraulic motor, a pressure roller cover plate, a pressure roller, a pressure roller bracket, a side transmission box, a side plate, an adjustment ground wheel mounting seat, a transmission shaft, a strip tillage roller, a strip tillage knife, a strip tillage knife shaft, and a hydraulic pump, wherein the strip tillage knife roller is composed of two groups of cutter discs with a strip tillage width of 310 mm, and the interval between the two groups of cutter discs corresponds to a 300 mm leisure belt. Through the operation of the strip tillage knife roller, two 310 mm strip tillage belts and a working plot with a 300 mm leisure belt sandwiched in the middle are formed.

[0005] A full-row-spacing strip tiller and a method for achieving full-row-spacing sowing, the method comprising the following steps:

[0006] Step 1. Use the full-row-spacing strip tiller to perform strip tillage on the cultivated land, forming a strip tillage block with a strip width of 310 mm and a fallow strip width of 300 mm;

[0007] Step 2. If you plan to plant in rows of (400mm, 900mm), (500mm, 800mm), (550mm, 750mm), (600mm, 700mm) and uniform ridges of 650mm, the spacing between adjacent strip plots will be 380mm. If you plan to plant in wide ridges of 700mm, the spacing between adjacent strip plots will be 480mm.

[0008] Step 3. Using an existing no-till seeder, sowing is performed on the plot of land that has been plowed in steps 1 and 2 using the full-row-spacing strip-till machine. The row spacing is between 400 mm and 700 mm. Regardless of the row spacing, sowing can be performed on the strip-till belt, thus achieving full-row-spacing sowing.

[0009] Step 4. Rotate the strip-till belt and fallow belt in the second year, that is, the strip-till belt in the second year becomes the fallow belt in the first year, and the fallow belt in the second year becomes the strip-till belt in the first year. The other steps are the same as above, thus realizing the agronomy of rotating fallow.

[0010] The present invention has the following advantages and positive effects:

[0011] 1. This invention changes the width of the strip-tillage belt and the width of the fallow belt, so that the working plot after strip-tillage adapts to the requirements of the sowing ridge spacing of all seeders, greatly reducing the disadvantages of inconsistent ridge spacing between adjacent plots of farmers and the interruption of continuous operation;

[0012] 2. The present invention divides the wide strip tillage belt into two small strip tillage belts with a small leisure belt in the middle. Compared with the existing strip tillage operation, it reduces moisture loss and soil erosion;

[0013] 3. Since the leisure belt is relatively small and sandwiched between the strip tillage belts, when strip tillage is carried out, the spread soil is pressed on the straw in the leisure belt, making the straw less likely to be blown away by the wind, which is more conducive to returning the straw to the field and sowing, so that the seedlings on the seedling belt will not be pressed by the moved straw, which will not affect the emergence and growth.

[0026] like Figure 4-Figure 5 As shown in Table 1: A full-row-spacing strip tiller and a method for achieving full-row-spacing sowing, the method comprising the following steps:

[0027] Step 1. Use the full-row-spacing strip-till machine to strip-till the cultivated land to form strip-till plots with a strip width of 310 mm and a fallow width of 300 mm, that is, to form strip-till plots corresponding to the values ​​of A, B, and C in Table 1;

That is, A = C = 310mm, B = 300mm, and D = 380mm. If you plan to plant in large, uniform ridges of 700mm, the spacing between two adjacent strip-tillage plots is 480mm. Other values ​​remain unchanged, so D = 480mm.

[0029] Step 3. Using an existing no-till seeder, sow on the plot that has been tilled in steps 1 and 2 using the full-row-spacing strip-till machine. The row spacing is between 400 mm and 700 mm. Regardless of the row spacing used, sowing can be performed on the strip-till belt, thus achieving full-row-spacing sowing.

[0030] Step 4. In the second year, the strip tillage belt and the fallow belt are rotated, that is, the strip tillage belt in the second year becomes the fallow belt in the first year, and the fallow belt in the second year becomes the strip tillage belt in the first year. The strip tillage parameters in other steps are the same as above. In this way, the agronomy of strip tillage and no-tillage rotation is realized, and the conditions of less soil movement, clean and flat seedling belts, and a warm upper and solid lower seedbed are achieved, laying the foundation for good seedling production and preservation.
