Description

Technical Field

[0001] The invention relates to the technical field of wheat sowing, in particular to a wheat sowing method and a variable seeding seeder. Background Art

[0002] In the process of modern agricultural production, wheat is one of the important food crops in my country. The optimization and improvement of its sowing method is of great significance to improving planting efficiency and ensuring crop quality. With the improvement of agricultural mechanization level, wheat seeder, as an efficient agricultural machinery equipment, has gradually occupied an important position in agricultural production.

[0003] As in the patent with prior art authorization announcement number CN201623982U, the purpose of the utility model is to provide a variable deep fertilization precision seeder that controls the amount of fertilizer according to local conditions and integrates variable deep fertilization and precision sowing. The utility model adopts a parallel four-bar profiling mechanism, a spoon-type precision seeding device and a narrow-core plowshare type furrow opener, which realizes accurate sowing amount, single-body profiling and single-body driven seeding, improves the soil penetration performance, reduces the slippage of the seeder, and ensures accurate sowing amount and plant spacing.

[0004] However, during the use of the seeder, it was found that the seeder was not convenient for achieving the effect of controlling and adjusting different plant spacings when sowing multiple rows simultaneously according to the sowing plant spacing requirements, which reduced the limitations of the sowing plant spacing adjustment. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a wheat sowing method and a variable seeding seeder that can improve the optimization effect of the wheat growth environment, increase the wheat planting yield, and improve the convenience of planting multiple rows of wheat at different plant spacings at the same time.

[0006] A wheat sowing method of the present invention comprises the following steps:

[0007] S1. By controlling the sowing spacing of the sowing equipment, the spacing between the four rows of wheat is maintained at 10 cm-13.3 cm, and the four rows of wheat are sown on a land 30 cm-40 cm wide;

[0008] S2. During the simultaneous sowing of four rows of wheat in S1, the spacing between the seeding legs of the sowing equipment is controlled so that the spacing between the two rows of wheat on the outermost sides is maintained at a distance of 10-13.3 cm, and the spacing between the two rows of wheat in the middle is maintained at a spacing of 20-30 cm, so that the wheat is sown in different row spacings;

[0009] S3. After the four rows of wheat are sown at the same time in S2, a 20 cm to 30 cm space is left on the sides of the four rows of wheat, and then four rows of wheat are sown in accordance with the wheat row spacing maintenance method in S2 until the farmland is fully planted;

[0010] S4. Based on S3, the spacing between the outer and inner rows of wheat in the four rows of wheat is adjusted by regulating the seed meter, so that the sowing amount of the two outer rows is increased by 20-25%, and the sowing amount of the two inner rows is reduced by 20-25%, so that wheat forms a sowing method with different row spacings and dense outside and sparse inside.

[0011] S5. After wheat is harvested, corn is sown in the 20-30 cm space left on the sides of every four rows of wheat;

[0012] S6. Lay drip irrigation tape between the 10cm-13.3cm open space in the middle of every four rows of wheat;

[0013] By adopting the sowing method of dense outside and sparse inside with different plant spacing for wheat sowing, the existing situation of the same sowing amount for each row of wheat is optimized, which causes the two middle rows of the four rows to be too crowded and the wheat side row advantages of the two outer rows on the left and right cannot be fully utilized.

[0041] S2. During the simultaneous sowing of four rows of wheat in S1, the spacing between the seeding legs of the sowing equipment is controlled so that the spacing between the two rows of wheat on the outermost sides is maintained at a distance of 10-13.3 cm, and the spacing between the two rows of wheat in the middle is maintained at a spacing of 20-30 cm, so that the wheat is sown in different row spacings;

[0042] S3. After the four rows of wheat are sown at the same time in S2, a 20 cm to 30 cm space is left on the sides of the four rows of wheat, and then four rows of wheat are sown in accordance with the wheat row spacing maintenance method in S2 until the farmland is fully planted;

[0043] S4. Based on S3, the spacing between the outer and inner rows of wheat in the four rows of wheat is adjusted by regulating the seed meter, so that the sowing amount of the two outer rows is increased by 20-25%, and the sowing amount of the two inner rows is reduced by 20-25%, so that wheat forms a sowing method with different row spacings and dense outside and sparse inside.

[0044] S5. After wheat is harvested, corn is sown in the 20-30 cm space left on the sides of every four rows of wheat;

[0045] S6. Lay drip irrigation tape between the 10cm-13.3cm open space in the middle of every four rows of wheat;

[0046] The following is a wheat production data table:

[0047] Sowing method Yield (kg / hectare) Traditional 15cm row spacing 8792.61 Different row spacing, dense outside and sparse inside mode 9754.38 Outside is dense, inside is sparse, and outside is professional 12559.22 Outside is dense, inside is loose, inside is expert 6949.54

[0048] A variable seeding seeder for wheat sowing comprises a driving device, an adjusting device, a furrowing device, a frame 101, a seed box 102, a plurality of first funnels 103, a plurality of conveying cylinders 104, a plurality of discharge pipes 105, a support shaft 106, a plurality of discs 107 and a plurality of feeding troughs 108. The seed box 102 is mounted on the upper inner wall of the frame 101, a feed port is arranged at the top of the seed box 102, a plurality of first funnels 103 are connected and arranged at the bottom of the seed box 102, a plurality of conveying cylinders 104 are mounted on the inner wall of the frame 101, and the bottoms of the plurality of first funnels 103 are connected to the plurality of conveying cylinders 104, respectively. The plurality of discharge pipes 105 are connected and connected to the top of the plurality of conveying cylinders 104. The support shaft 106 is rotatably installed on the inner wall of the frame 101 by the driving device. The plurality of discs 107 are respectively slidably adjusted left and right by the adjusting device and installed on the outer wall of the support shaft 106. The plurality of discs 107 are respectively arranged inside the plurality of conveying cylinders 104. The plurality of feeding troughs 108 are respectively circumferentially arranged on the outer walls of the plurality of discs 107. Each group of circumferentially arranged feeding troughs 108 is respectively arranged at different intervals. A furrowing device is arranged at the lower part of the frame 101. The furrowing device is used to plow furrows on the ground.

[0049] In this embodiment, wheat is sown by adopting a sowing method with different plant spacings of dense outside and sparse inside, which optimizes the existing situation in which the same sowing amount of wheat in each row results in the two middle rows of four rows being too crowded, and the wheat side row advantages of the two outer rows on the left and right cannot be fully utilized, thereby improving the optimization effect of the wheat growth environment. Wheat seeds are placed in the seed box 102, and the wheat seeds in the seed box 102 flow downward through the multiple groups of first funnels 103 under the force of gravity and are discharged into the multiple groups of conveying cylinders 104. The seeds entering the conveying cylinders 104 fall into the feeding troughs 108 at the top. When the frame 101 moves forward, the driving device drives the support shaft 106 to rotate, so that the support shaft 106 drives the multiple groups of discs 107 to rotate, thereby causing the multiple groups of feeding troughs 108 to move circumferentially The seeds are automatically transported downward, and the seeds transported downward are discharged downward through the discharge pipe 105 and fall into the plowed grooves, thereby realizing automatic sowing of wheat. When it is necessary to adjust the plant spacing of multiple rows of wheat planted at the same time, the disc 107 is driven to move left or right for adjustment through the adjustment device, so that the feeding troughs 108 with different spacings are switched and moved to the bottom end of the first funnel 103. Therefore, when the support shaft 106 drives multiple groups of discs 107 to rotate, the feeding troughs 108 with different spacings can achieve the effect of sowing wheat with different front and back plant spacings. By moving the furrowing device left and right for adjustment, it is convenient to adjust the left and right plant spacing of multiple rows of wheat, thereby improving the convenience of planting multiple rows of wheat planted at the same time with different plant spacings, optimizing the wheat sowing method, and increasing wheat yield.

[0059] In this embodiment, when the frame 101 moves forward, the lifting device drives multiple groups of plowshares 205 to move downward, so that the multiple groups of plowshares 205 plow the ground, and then the wheat seeds discharged from the discharge pipe 105 fall into the second funnel 204, and the seeds are diverted and discharged into the furrows through the second funnel 204. As the frame 101 continues to move forward, the multiple groups of covering wheels 209 respectively move the soil on both sides of the furrows to the middle, so that the furrows after sowing are covered with soil, and then the furrows covered with soil are rolled and flattened by the pressing device, thereby improving the integrated effect of automatic plowing, seeding, covering and rolling of wheat by the seeder, and improving the wheat sowing efficiency. By controlling the telescopic length of the moving ends of the multiple groups of first hydraulic cylinders 203, the multiple groups of first hydraulic cylinders 203 respectively drive the multiple groups of brackets 202 to move left and right to adjust The structure of the present invention improves the convenience of adjusting the spacing between multiple groups of brackets 202, and improves the convenience of adjusting the left and right plant spacing of wheat. When the frame 101 moves forward, the two groups of support wheels 302 contact the ground to support the frame 101, thereby improving the walking stability of the frame 101. After the left support wheel 302 rotates, it drives the first group of first pulleys 304 to rotate. The two groups of first pulleys 304 are driven by the first belt 305 to drive the transmission 303. After the output end of the transmission 303 changes speed, it drives the first group of second pulleys 306 to rotate, so that the two groups of second pulleys 306 drive the support shaft 106 to rotate through the transmission of the second belt 307, thereby improving the convenience of the support shaft 106 driving multiple groups of discs 107 to rotate, and improving the convenience of controlling the sowing speed according to the travel speed of the frame 101.

[0060] like Figures 1 to 12 As shown, a wheat sowing method and a variable seeding seeder of the present invention, when working, put wheat seeds into the seed box 102, and the wheat seeds in the seed box 102 flow downward through multiple groups of first funnels 103 under gravity and are discharged into multiple groups of conveying cylinders 104, and the seeds entering the conveying cylinders 104 fall into the top feeding troughs 108. When the frame 101 moves forward, the driving device drives the support shaft 106 to rotate, so that the support shaft 106 drives the multiple groups of discs 107 to rotate, so that the multiple groups of feeding troughs 108 move circumferentially to convey the seeds downward. The seeds are discharged downward through the discharge pipe 105 and fall into the plowed grooves, thereby realizing automatic sowing of wheat. When it is necessary to adjust the plant spacing of multiple rows of wheat planted at the same time, the disc 107 is driven to move left or right through the adjustment device to switch and move the feeding troughs 108 with different spacings to the bottom end of the first funnel 103. When the support shaft 106 drives multiple groups of discs 107 to rotate, the feeding troughs 108 with different spacings can achieve the effect of sowing wheat with different plant spacings in the front and back. By moving the furrowing device left and right, the left and right plant spacing of multiple rows of wheat can be adjusted.

[0061] The main functions achieved by the present invention are as follows: by adopting a sowing method of different plant spacings with dense outside and sparse inside to sow wheat, the existing situation in which the sowing amount of each row of wheat is the same, resulting in the two middle rows of four rows being too crowded and the wheat side row advantages of the two outer rows on the left and right cannot be fully utilized; the sowing effect of different plant spacings before and after wheat and the sowing effect of adjusting the plant spacings on the left and right are achieved, the convenience of planting wheat with different plant spacings in multiple rows at the same time is improved, the wheat sowing method is optimized, and the wheat yield is increased.

[0062] The first hydraulic cylinder 203, the transmission 303 and the second hydraulic cylinder 603 of the wheat sowing method and the variable seeding seeder of the present invention are purchased on the market. The technicians in this industry only need to install and operate them according to the accompanying instruction manual without the need for the technicians in this field to make creative efforts.

[0063] 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 technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
