[0013] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0014] The following further describes the utility model in detail in conjunction with the embodiments.

[0015] As Figure 1 and Figure 2 shown, a specific embodiment of a power support of a seeding machine provided by the utility model:

[0016] A power support of a seeding machine includes a seeding box 1, a seeding drive disk 2 and two push rods 3. The seeding box 1 is arranged at the front ends of the two push rods 3. The seeding drive disk 2 is arranged on the seeding box 1. The middle parts of the two push rods 3 are fixedly connected through a connecting shaft 4. A sleeve 5 is sleeved outside the connecting shaft 4. Two fastening bolts 6 are threadedly connected to the sleeve 5. The ends of the fastening bolts 6 are in pressing contact with the outer wall of the connecting shaft 4. By the pressing contact between the fastening bolts 6 and the connecting shaft 4, the relative positions of the sleeve 5 and the connecting shaft 4 can be fixed.

[0017] At the bottom of the casing 5, two vertical pipes 7 are fixedly arranged side by side. A transmission wheel 8 is installed between the two vertical pipes 7. The transmission wheel 8 is driven by a motor, and the motor can also be installed between the two vertical pipes 7 through a support. The transmission wheel 8 is connected to the driving disc 2 through a transmission belt 9. Flower basket bolts 10 are respectively connected between the two push rods 3 and the two vertical pipes 7. Loosen the fastening bolt 6 and adjust the telescopic length of the flower basket bolt 10, then the vertical pipe 7 can be rotated around the connecting shaft 4, thereby changing the tension of the transmission belt 9. After adjustment, tighten the fastening bolt 6.

[0018] The lower ends of the two vertical pipes 7 are fixedly connected through a fixed shaft 11. A wheel support 12 is hinged on the fixed shaft 11. The wheel support 12 can move around the fixed shaft 11. A pressing wheel 13 is rotatably installed on the wheel support 12. A torsion spring 14 is arranged on the fixed shaft 11. The torsion spring 14 acts on the wheel support 12, and the torsion force of the torsion spring 14 is applied to the wheel support 12. The wheel support 12 has the potential energy to rotate clockwise, so as to ensure that the pressing wheel 13 is more easily attached to the ground. A limiting plate 15 is fixed at the end of the wheel support 12. An installation seat 16 is fixed between the lower ends of the two vertical pipes 7. The installation seat 16 is located above the fixed shaft 11. A long bolt 17 is threadedly connected to the installation seat 16. The end of the long bolt 17 is in pressing contact with the limiting plate 15. The long bolt 17 plays a limiting role to limit the clockwise rotation range of the wheel support 12.

[0019] In addition, the connection relationship between the torsion spring 14 and the wheel support 12 can also be limited to adjust the torsion force of the torsion spring 14. Specifically, a stop piece 18 is welded on the wheel support 12. A through hole is opened on the stop piece 18. A hole eye bolt 19 is inserted into the through hole. The end of the arm rod 20 of the torsion spring 14 is inserted into the hole of the hole eye bolt 19. The other end of the hole eye bolt 19 is connected with a nut 21. The nut 21 is in pressing contact with the stop piece 18. When adjusting the torsion force of the torsion spring 14, rotate the nut 21, then the relative position between the hole eye bolt 19 and the stop piece 18 can be changed, and finally the position of the end of the arm rod of the torsion spring 14 is changed to complete the adjustment of the torsion force of the torsion spring 14.
