Technical Field

[0001] The utility model relates to the technical field of sowing trays, in particular to an adjustable soybean sowing tray. Background Technique

[0002] A pneumatic suction seeder is a sowing tool commonly used in agricultural production. It uses the principle of air flow to adsorb seeds onto the sowing tray, and then evenly scatters the seeds into the soil through certain mechanical operations. It is often used in soybean sowing. An air flow is generated by a blower or a pneumatic pump to adsorb soybean seeds onto the sowing tray, and quantitative sowing is carried out by the rotation of the sowing tray.

[0003] However, the existing sowing trays generally have pre-set quantitative pneumatic suction holes. After the sowing tray is installed, quantitative sowing is carried out through continuous single-circle rotation. When sowing soybeans, due to reasons such as sowing area and soil conditions, the sowing quantity of soybeans also needs to be adjusted accordingly. Therefore, when using this kind of quantitative sowing tray, it is very difficult to adjust the sowing quantity according to the above conditions.

[0004] Therefore, it is necessary to design an adjustable soybean sowing tray to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] Obviously, many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Please refer to Figures 1-4, the present utility model provides an adjustable soybean sowing disk, which includes a sowing disk body 1. Grooves are formed on the outer surface of the sowing disk body 1, and multiple groups of soybean air suction ports 2, each group consisting of three and distributed circumferentially, are formed on the outer surface of the grooves. A raised end 16 is provided on the sowing disk body 1, and an annular groove 3 is formed on the outer surface of the raised end 16. A collar 12 is rotatably sleeved inside the annular groove 3, and a plurality of circumferentially distributed fixed boxes 8 are fixedly connected to the outer surface of the collar 12. A slot is formed inside the fixed box 8. A spring 15 is fixedly connected to the outer surface of the collar 12 on one side of the slot, and one end of the spring 15 is fixedly connected to a telescopic block 10. The telescopic block 10 is slidably inserted into the slot. A square opening is formed on the outer surface of the fixed box 8, and an adjusting column 9 is fixedly connected to one side of the telescopic block 10. The adjusting column 9 is slidably arranged inside the square opening. Two adjacent first threaded holes 17 are formed on the outer surface of the raised end 16, and another two first threaded holes 17 are formed on the outer surface of the collar 12. First bolts 5 are threadedly inserted into the two first threaded holes 17 on the collar 12, and the collar 12 is threadedly connected to the raised end 16 through the two first bolts 5. A rotating groove 11 is formed on the outer surface of the raised end 16, and two symmetrically arranged insertion posts 14 are slidably inserted into the rotating groove 11. An adjusting disk 13 is fixedly connected to the two insertion posts 14. Two adjacent second threaded holes 18 are formed on the outer surface of the raised end 16, and two second bolts 6 are threadedly inserted into the outer surface of the adjusting disk 13. The adjusting disk 13 is threadedly connected to the outer surface of the raised end 16 through the two second bolts 6. A plurality of arc-shaped convex blocks matching the plurality of adjusting columns 9 are arranged on the outer surface of the adjusting disk 13. The adjustment of the sowing disk body 1 is divided into two steps, respectively controlling each group of three soybean air suction ports 2 on the sowing disk body 1. First, by connecting the two second bolts 6 to the second threaded holes 18 in pairs on the raised end 16 respectively, the adjusting disk 13 can be rotated and adjusted on the outer surface of the raised end 16, and fixed at two different positions through the second bolts 6. During the rotation of the adjusting disk 13, the plurality of arc-shaped convex blocks on the adjusting disk 13 will, under the elasticity of the spring 15, adjust the position of each adjusting column 9 inside the fixed box 8, so as to adjust the position of the telescopic block 10 inside the groove of the sowing disk body 1 by elastic contraction, thereby facilitating the opening or closing of the second soybean air suction port 2 in each group. By adjusting the position of the adjusting disk 13, it is convenient to select whether to expose one or two soybean air suction ports 2 in each group when the sowing disk body 1 is working. Thus, when the sowing disk body 1 rotates, one different soybean is sucked in each single circle, so as to perform one adjustment. After the adjustment of the adjusting disk 13, if it is necessary to open the third soybean air suction port 2 in each group, the connection between the two first bolts 5 and the first threaded holes 17 in pairs is used to adjust the position of the collar 12 inside the annular groove 3.Thereby, the position of each fixed connection box 8 inside the groove is adjusted. When multiple fixed connection boxes 8 are all turned away from each group of soybean air suction ports 2, the three soybean air suction ports 2 in each group will all be exposed. Thus, the number of soybeans that can be sucked by the seeding disk body 1 is adjusted again, and thus the number of seeds sown in each circle when the seeding disk body 1 rotates is adjusted. Through the above-mentioned secondary adjustment method, the seeding disk body 1 can be adjusted for various numbers of soybean sowing, making the seeding disk body 1 more practical and adaptable.

[0021] To facilitate the use of the sliding of the telescopic block 10 inside the fixed connection box 8 to adjust the number of soybeans that can be sucked by each group of soybean air suction ports 2, one side of multiple fixed connection boxes 8 and the telescopic block 10 is in close contact with the inside of the groove of the seeding disk body 1. And the top of the telescopic block 10 is provided with an arc surface, and multiple telescopic blocks 10 are respectively slidably arranged on multiple groups of soybean air suction ports 2.

[0022] And in order to better disassemble and assemble the first bolt 5, thereby adjusting the positions of the collar 12 and multiple fixed connection boxes 8, a slotted opening is provided at the top of the first bolt 5, and multiple circumferentially distributed mounting holes 4 are provided on the outer surface of the convex end 16, and multiple mounting holes 4 are located between the two first bolts 5 and the rotating groove 11 on the outer surface of the convex end 16.

[0023] Furthermore, in order to use multiple arc-shaped convex blocks to cooperate with multiple springs 15 to simultaneously adjust the positions of multiple adjusting columns 9 on multiple fixed connection boxes 8, multiple adjacent arc-shaped convex blocks on the adjusting disk 13 are connected to each other, and the tops of multiple arc-shaped convex blocks are respectively in close contact with the outer surfaces of multiple adjusting columns 9, and a notch is formed between every two arc-shaped convex blocks.

[0024] Even further, for the convenience of installation and operation stability of the seeding disk body 1, the adjusting disk 13 is rotatably arranged on the outer surface of the convex end 16, and the outer surface of the adjusting disk 13 and the outer surface of one side of the seeding disk body 1 are on the same horizontal plane.
