Through the arrangement of the precision seeder 3 and the seeding pipe 4, precision seeding work can be carried out on the peanut seeds. Through the arrangement of the ridging plow head 5, the soil can be plowed into grooves, facilitating seeding. Through the arrangement of the support bar 6, the sliding sleeve 7 can be supported. Through the arrangement of the sliding sleeve 7, the ridging plow head 5 can be supported.

[0032] Specifically, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 shown, the fixing assembly 9 includes a fixing frame 901. The two sides at the rear of the fixing frame 901 are respectively fixedly connected to the two sides at the front of the sliding sleeve 7. A handle 902 is provided on the front side of the fixing frame 901. A fixing pin 903 is fixedly connected to the rear side of the handle 902. The rear side of the fixing pin 903 sequentially penetrates through the fixing frame 901 and the sliding sleeve 7 and extends into the inner cavity of the fixing hole 10. A spring 904 and a limit plate 905 are sequentially sleeved on the surface of the fixing pin 903 from front to back. The front side and the rear side of the spring 904 are respectively fixedly connected to the front side of the inner wall of the fixing frame 901 and the front side of the limit plate 905. The inner wall of the limit plate 905 is fixedly connected to the surface of the fixing pin 903. The two sides of the limit plate 905 are slidably connected to the two sides of the inner wall of the fixing frame 901. The rear side of the limit plate 905 contacts the front side of the sliding sleeve 7.

[0033] Specifically, as Figure 6As shown, a perforation 11 for cooperating with a fixed pin 903 is formed on the front side of the fixing bracket 901, and the surface of the fixed pin 903 is slidably connected to the inner wall of the perforation 11.

[0034] Specifically, as Figure 6 shown, a through hole 12 for cooperating with the fixed pin 903 is formed on the front side of the sliding sleeve 7, and the surface of the fixed pin 903 is slidably connected to the inner wall of the through hole 12.

[0035] In this embodiment: By providing the fixing bracket 901, the handle 902, the fixed pin 903, the spring 904 and the limiting plate 905, during use, the position of the fixed pin 903 can be positioned through the fixing bracket 901, the fixed pin 903 can be conveniently pulled and moved through the provision of the handle 902, the position of the sliding sleeve 7 can be fixed by inserting the fixed pin 903 into the fixing hole 10, and through the provision of the spring 904 and the limiting plate 905, the spring force of the spring 904 presses on the limiting plate 905, and the limiting plate 905 presses on the fixed pin 903, so that the fixed pin 903 cannot be removed from the fixing hole 10, increasing the fixing stability of the fixed pin 903 to the sliding sleeve 7.

[0036] Specifically, as Figure 1 、 Figure 2 、 Figure 3 shown, first reinforcing ribs 13 are fixedly connected to both sides of the top of the support plate 801, and the side of the first reinforcing ribs 13 close to the frame body 1 is fixedly connected to the frame body 1.

[0037] Specifically, as Figure 1 、 Figure 2 shown, a mounting strip 14 is fixedly connected to the front side of the support plate 801, and second reinforcing ribs 15 are fixedly connected to both sides of the mounting strip 14, and the side of the second reinforcing ribs 15 close to the support plate 801 is fixedly connected to the support plate 801.

[0038] In this embodiment: By providing the first reinforcing ribs 13, the connection stability between the support plate 801 and the frame body 1 can be increased. By providing the mounting strip 14, the device can be mounted to the driving vehicle. By providing the second reinforcing ribs 15, the connection stability between the mounting strip 14 and the support plate 801 can be increased.

[0039] Specifically, as Figure 1 、 Figure 2 、 Figure 4 shown, limiting rods 16 are fixedly connected to both sides of the top of the support bar 6, the tops of the limiting rods 16 penetrate through the support plate 801, and the surface of the limiting rods 16 is slidably connected to the inner wall of the support plate 801.

[0040] Specifically, as Figure 1 、 Figure 2, Figure 3 As shown in Figure 3 , support blocks 17 are fixedly connected to the rear sides of both sides of the bottom of the frame body 1, and a soil covering roller 18 is rotatably connected between the two support blocks 17.

[0041] In this embodiment: By providing the limit rod 16, the position of the support strip 6 can be limited to prevent the support strip 6 from shaking. By providing the support block 17, the soil covering roller 18 can be supported and positioned. By providing the soil covering roller 18, the soil covering work for peanut seeds can be carried out after sowing.

[0042] Working principle: When in use, the device is connected and installed to the driving vehicle through the installation strip 14. Then, peanut seeds are loaded into the seed bin 2. Then, the ridging plow head 5 plows out a groove in the soil. Sowing work is carried out through the precision seeder 3 and the sowing pipe 4. The soil covering work is carried out by the soil covering roller 18 after sowing. When it is necessary to adjust the sowing depth, the hydraulic cylinder 802 can be started, so that the output end of the hydraulic pipe drives the connecting block 804 to move up and down. The connecting block 804 drives the support strip 6 to adjust the height up and down, so that the support strip 6 drives the sliding sleeve 7 to move up and down. The sliding sleeve 7 drives the ridging plow head 5 to move up and down to adjust the height of the ridging plow head 5. By adjusting the height of the ridging plow head 5, the ridging plow head 5 can plow out a groove with the required depth in the soil, so as to achieve the effect of adjusting the sowing depth. When it is necessary to adjust the sowing spacing, the handle 902 can be pulled. The handle 902 drives the fixed pin 903 to move out of the inner cavity of the fixing hole 10, thereby canceling the fixation of the sliding sleeve 7. When the pin moves out of the fixing hole 10, it will drive the limiting plate 905 to squeeze the spring 904. Then, the sliding sleeve 7 is moved on the surface of the support strip 6 to adjust the spacing of the ridging plow head 5. After moving to a suitable position, the handle 902 is released. Then, the spring 904 will drive the limiting plate 905 to move in the reverse direction through the force released after compression. The limiting plate 905 drives the fixed pin 903 to move in the reverse direction, so that the fixed pin 903 is inserted into the fixing hole 10 to fix the position of the sliding sleeve 7. The operation is relatively convenient. Since the outlet of the sowing pipe 4 is fixedly connected to the ridging plow head 5, the effect of conveniently adjusting the sowing spacing can be achieved.

[0043] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
