Description

Technical Field

[0001] This utility model belongs to the field of crop sowing, specifically a strip-shaped composite planting device for crops. Background Technology

[0002] Strip intercropping refers to an agricultural planting model in which two or more crops (such as corn and soybeans, wheat and rapeseed, etc.) are planted alternately in strips of a certain width and spacing within the same plot. Its core is to improve land utilization, light energy utilization and resource competitiveness by rationally configuring crop types and planting strip widths and utilizing the growth characteristics of different crops (such as tall and short crops, and complementary root depths), so as to achieve increased production and efficiency and ecological compatibility. It is a highly efficient planting technology suitable for large-scale agricultural production.

[0003] Seeders are key equipment for mechanized crop planting. Their main function is to quantitatively and precisely sow seeds into the soil according to preset row and plant spacing, and to complete auxiliary operations such as covering and compacting the soil, replacing manual sowing to improve planting efficiency and ensure sowing quality.

[0004] In strip intercropping, the different growth characteristics of various crops require specific spacing during seed sowing (e.g., the row spacing between tall and short crops needs to accommodate ventilation and light penetration, while the spacing between legumes and grasses needs to match root distribution). However, existing seed hoppers and seed metering mechanisms are mostly fixed structures. Adjusting parameters such as the relative position of the hopper and the seed metering components, and the seeding frequency, is cumbersome. Adjusting the sowing spacing for different crops often requires disassembling and replacing transmission gears, adjusting the hopper's installation position, or manually calibrating the seed metering wheel speed. This is not only complex and time-consuming but also makes it difficult to guarantee adjustment accuracy, easily leading to deviations in the spacing between different crop strips and affecting the intercropping effect. This structural limitation makes it difficult for existing seeders to flexibly adapt to the needs of strip intercropping of multiple crops, reducing the continuity and efficiency of planting operations and hindering the large-scale promotion of strip intercropping technology. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a strip-planting and sowing device for crops, thereby solving the problems of poor adaptability and cumbersome adjustment of existing seeders.

[0007] The spreading mechanism includes a connecting rod, which is symmetrically welded to the top of one side of the movable part. Several movable blocks are movably installed on the outer surface of the connecting rod. A support plate is fixedly installed on the upper surface of the movable block. A second storage hopper is provided at the top edge of the support plate.

[0008] The fixed groove is also equipped with a transmission structure for controlling the position of the moving part in the fixed groove.

A connecting handle is provided on one side of the lead screw extending to the outside of the fixed frame. A fixed rod is fixedly installed on the other end of the inner wall of the fixed groove. The movable part is movably sleeved on the outer surface of the lead screw and the fixed rod.

[0010] Preferably, a connecting support plate is fixedly installed on one side of each of the two connecting rods, and a support wheel is rotatably installed on the bottom side of one side of the connecting support plate.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a strip-shaped composite planting device for crops, including a seeder 1, a first storage hopper 2 arranged side by side at the top of the seeder 1, a connecting push rod 3 fixedly installed at one end of the seeder 1, a fixed frame 4 fixedly installed at the front end of the seeder 1, a fixed groove 5 opened on the upper surface of the fixed frame 4, a movable part 8 movably installed inside the fixed groove 5, and a sowing mechanism is provided on one side of the movable part 8 extending to the outside of the seeder 1 for sowing different crop seeds.

[0026] The spreading mechanism includes connecting rods 9, which are symmetrically welded to the top of one side of the movable part 8. Connecting support plates 10 are fixedly installed on one side of the two connecting rods 9. Support wheels 11 are rotatably installed on the bottom of one side of the connecting support plates 10. Several movable blocks 12 are movably installed on the outer surface of the connecting rods 9. Support plates 13 are fixedly installed on the upper surface of the movable blocks 12. A second storage hopper 14 is provided at the top edge of the support plate 13.

[0027] A through hole is symmetrically opened on one side of the movable block 12. A first threaded hole is opened on both sides of the bottom end of the movable block 12 and extends into the through hole. A positioning bolt 15 is installed at the bottom end of the movable block 12 in the first threaded hole. The top of the positioning bolt 15 abuts against the outer surface of the connecting rod 9.

[0028] The fixed groove 5 is also equipped with a transmission structure to control the position of the moving part 8 in the fixed groove 5.

[0029] As can be seen from the above, firstly, according to the strip intercropping scheme (such as strip planting of corn and soybeans, the spacing between corn and soybeans needs to be adjusted), the target spacing of the second storage hopper 14 is determined; then, the positioning bolt 15 at the bottom of the movable block 12 is loosened, the movable block 12 is slid along the connecting rod 9, and the spacing between adjacent second storage hoppers 14 is adjusted; after adjustment, the positioning bolt 15 is tightened to lock the position of the movable block 12.

[0030] Then, slide the movable part 8 along the fixed groove 5 to adjust the overall lateral position of the sowing mechanism, thereby making the support wheel 11 stably support the movable block 12 on the connecting rod 9 to ensure structural stability. Push the connecting push rod 3 to make the seeder 1 move forward to carry out sowing operations, so that the first storage hopper 2 can cooperate with the second storage hopper 14 to carry out compound planting of different crops.

[0031] Example 2:

[0032] Reference Figure 2 and Figure 3 The transmission structure includes a lead screw 6, which is rotatably installed at one end of the inner wall of the fixed groove 5. A connecting handle 16 is provided on one side of the lead screw 6 extending to the outside of the fixed frame 4. A fixed rod 7 is fixedly installed at the other end of the inner wall of the fixed groove 5. A movable part 8 is movably sleeved on the outer surface of the lead screw 6 and the fixed rod 7.

[0033] A second threaded hole is provided through one side of the movable part 8, and one side of the outer surface of the lead screw 6 is located in the second threaded hole. The lead screw 6 and the second threaded hole are adapted to each other. A fixing hole is provided through one side of the movable part 8 away from the second threaded hole, and one side of the outer surface of the fixing rod 7 is located in the fixing hole. The fixing rod 7 and the fixing hole are fitted together.

[0034] As can be seen from the above, firstly, the lateral displacement distance that the spreading mechanism needs to be adjusted is determined. Then, hold the connecting handle 16 and rotate it. The lead screw 6 will rotate at the rotating mounting point on the inner wall of the fixed groove 5. Because the second threaded hole on one side of the movable part 8 is compatible with the lead screw 6, when the lead screw 6 rotates, the movable part 8 will move along the axial direction of the lead screw 6. At the same time, under the limit of the fixed rod 7, the fixed rod 7 passes into the fixed hole of the movable part 8, restricting the rotation of the movable part 8 and ensuring that it can only slide in a straight line and slide smoothly in the fixed groove 5.

[0035] Then, when the movable part 8 slides to the target position, due to the self-locking property of the threaded engagement between the lead screw 6 and the second threaded hole, and the limiting effect of the fixed rod 7 on the movable part 8, the movable part 8 can be stably stopped in the adjusted position, which provides a guarantee for the subsequent precise sowing of different crop seeds and the realization of the positional accuracy requirements of strip intercropping.

[0036] Working principle: During the spacing adjustment and locking process, when adjusting the spacing of the second storage hopper 14, the movable block 12 fits onto the connecting rod 9 through the through hole. Loosening the positioning bolt 15 releases the fixed constraint and allows for free sliding adjustment of the spacing. After tightening, the top of the positioning bolt 15 presses against the outer surface of the connecting rod 9, locking the position with friction. When adjusting the lateral position of the spreading mechanism, rotating the connecting handle 16 causes the lead screw 6 to rotate. The movable part 8 undergoes axial displacement due to the adaptation between the second threaded hole and the lead screw 6, and the fixed rod 7, inserted into the fixed hole of the movable part 8, restricts its rotation, allowing it to slide linearly along the fixed groove 5. With precise positioning, the support wheel 11 provides additional support and enhances stability when in contact with the ground. During sowing, the seeder 1 moves forward, and the seeds in the first hopper 2 are sown at a preset row spacing by its own seed dispensing mechanism to form the basic crop strip. The seeds in the second hopper 14 move with the sowing mechanism and are sown synchronously at the adjusted spacing to form the composite crop strip. The support wheel 11 rolls to assist in movement and avoids sowing deviation caused by ground undulations. The fixed frame 4 and the transmission structure ensure the stability of the sowing mechanism and ensure the precise spacing of different crop strips, realizing the mechanized operation of strip composite planting.

[0037] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
