Description

Technical Field

[0001] The utility model relates to the technical field of peanut sowing, in particular to an adjustable sowing device for peanut planting. Background Art

[0002] A peanut seeding device is an agricultural machine used to evenly plant peanut seeds in a field. The device can adjust the seeding rate and seeding depth mechanically or electronically to ensure that the seeds are evenly distributed and buried at the appropriate depth in the soil.

[0003] At present, when using the sowing device for peanut planting, a seed box for storing seeds is required for storing and transporting peanut seeds. However, the sizes of peanut seeds are not uniform. Seeds of inconsistent sizes are prone to uneven falling during the sowing process. Larger seeds may block the seeding port, while smaller seeds may fall excessively, resulting in uneven distribution of seeds in the field and over-dense sowing in some areas. This uneven distribution will affect the growth consistency and final yield of peanuts. Therefore, it is necessary to redesign an adjustable sowing device for peanut planting to address the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , an adjustable sowing device for peanut planting, comprising a seed box 1, the center position of the upper end of the seed box 1 is open, and a feeding plate 2 is provided here, a discharging pipe is installed at the lower end of the seed box 1, a sieve plate 6 is slidably connected in the seed box 1, and the surface area of ​​the sieve plate 6 is an open area above the seed box 1, a reciprocating screw 7 is rotatably connected to the inner wall of the seed box 1, and a screw sleeve 10 is threadedly connected to the threaded section of the reciprocating screw 7, and the screw sleeve 10 is connected to the sieve plate 6 through a connecting mechanism. A through groove 5 is opened on the outer wall of the seed box 1, and a baffle 4 is rotatably connected at the through groove 5. The connecting mechanism includes a fixed block 11 fixedly connected to the lower end surface of the sieve plate 6, and a fixed groove 12 is opened on the outer wall of the screw sleeve 10. The fixed block 11 is slidably connected to the outer wall of the fixed groove 12. By means of the sieve plate 6, the peanut seeds falling onto the sieve plate 6 can be screened, and the peanut seeds with larger volume can be screened out, so as to ensure that there will be no uneven distribution during subsequent planting, and avoid affecting the consistency of peanut growth and the final yield.

[0023] Reference Figure 2 and Figure 4 The outer wall of the fixed block 11 and the inner wall of the fixed groove 12 are both T-shaped, the fixed block 11 contacts the inner wall of the fixed groove 12, the inner wall of the seed box 1 is fixedly connected to the limit rod 8, the screw sleeve 10 is slidably connected to the outer wall of the limit rod 8, the outer wall of the reciprocating screw 7 is fixedly connected to two groups of limit rings 9, the positions of the two groups of limit rings 9 are symmetrical to each other, the outer wall of the screw sleeve 10 is slidably connected to a pin 13, one end of the pin 13 passes through the body of the screw sleeve 10 and extends to the inside of the fixed block 11, the end of the pin 13 is fixedly connected to a slide plate 15, the outer wall of the slide plate 15 is fixedly connected to a spring 14, and the other end of the spring 14 is fixedly connected to the outer wall of the screw sleeve 10;

[0024] By controlling the sliding of the sieve plate 6, the peanut seeds can be laid flat on its upper end, thereby increasing the screening speed and preventing larger seeds from clogging the mesh of the sieve plate 6 and affecting the screening efficiency. The sieve plate 6 can be quickly disassembled by setting components such as the pin 13, and then the larger seeds can be uniformly collected by extracting the sieve plate 6.
