Description

Technical Field

[0001] This utility model relates to the field of leveling mechanisms, and in particular to a leveling mechanism for a wheat planter. Background Technology

[0002] The leveling process after wheat sowing is a crucial step in ensuring a stable environment for seed germination, improving emergence rate, and promoting vigorous growth in the later stages. The core objectives are to ensure close contact between the soil and seeds to achieve "soil-seed compatibility," level the ground surface, reduce water evaporation, and prevent air leakage and moisture loss.

[0003] When leveling the soil, it is usually necessary to use a rake to lightly rake along the sowing direction 1-2 times, and then use a roller to level the land. However, due to the large size of the plot, it is easy to miss some areas when using the rake to break up the soil and perform initial leveling. Therefore, it is usually necessary to check manually and break up large bumps. The inspection process is slow, inefficient, and labor-intensive. In view of this, we propose a leveling mechanism for wheat planters. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This wheat seeder uses a leveling mechanism that utilizes the movement of the wheels in conjunction with the automatic pressing component to achieve the vertical reciprocating motion of the pressing plate. This, in turn, works with the crushing nails to break up large clods of soil on the ground, preventing the formation of empty layers beneath the soil due to the presence of large clods, which would otherwise cause the seeds to lack water.

The wheat planter uses a leveling mechanism that, with the help of springs to provide movement space for the pressure plate, can automatically retract when the crushing nails come into contact with stones to avoid damage to the crushing nails. At the same time, the cooperation of the first and second pulleys can transform the slow rotation of the wheels into the rapid vertical movement of the pressure plate, reducing energy consumption without the need for additional drive.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a leveling mechanism for a wheat planter, including a frame 1. Two vertical support plates 2 are fixedly connected to the lower surface of the frame 1. Wheels 3 are rotatably connected to the two vertical support plates 2 on their opposite sides. A first guide rod 4 is fixedly connected to the lower surface of the frame 1. A limiting disc 5 is fixedly connected to the lower end of the first guide rod 4. A displacement drive plate 6 is slidably sleeved on the outer surface of the first guide rod 4. The first guide rod 4 restricts the movement trajectory of the displacement drive plate 6, allowing it to move only in the vertical direction. A second guide rod 7 is fixedly connected to the lower surface of the displacement drive plate 6. The limiting disc 5 is also fixedly connected to the lower end of the second guide rod 7.

[0024] The second guide rod 7 has a sliding mounting plate 8 on its outer surface. The second guide rod 7 restricts the movement trajectory of the mounting plate 8. A spring 26 is fixedly connected between the mounting plate 8 and the displacement drive plate 6. The spring 26 provides a flexible connection between the mounting plate 8 and the displacement drive plate 6, allowing the mounting plate 8 to float. An electric telescopic rod 9 is fixedly connected to the lower surface of the mounting plate 8. A pressure plate 10 is fixedly connected to the telescopic end of the electric telescopic rod 9. A crushing nail 11 is fixedly connected to the lower surface of the pressure plate 10. The crushing nail 11 is used to crush the soil clods. An automatic pressing component is provided on the vertical support plate 2. The movement of the wheel 3, in conjunction with the automatic pressing component, enables the pressure plate 10 to move vertically back and forth. This, in conjunction with the crushing nail 11, crushes large soil clods on the ground, preventing the formation of a void layer beneath the soil clods and thus preventing seed dehydration.

[0025] Furthermore, the automatic pressing component includes two protective shells 12, which are fixedly connected to the adjacent surfaces of the two vertical support plates 2. The protective shells 12 protect the internal structure and prevent dirt and dust from entering and obstructing the movement of the structure. The adjacent surfaces of the two wheels 3 are each fixedly connected to a drive shaft 13, which rotatably penetrates into the interior of the two protective shells 12. The outer surfaces of the two drive shafts 13 inside the protective shells 12 are each fixedly fitted with a first pulley 14. The adjacent surfaces of the two protective shells 12 are each rotatably connected to a rotating disk 15, and the distant surfaces of the two rotating disks 15 are each fixedly connected to a synchronous shaft 16.

[0026] The end of the synchronous shaft 16 also rotates through into the interior of the protective shell 12. The outer surface of the synchronous shaft 16 inside the protective shell 12 is fixedly fitted with a second pulley 17. A transmission belt 18 is sleeved between the second pulley 17 and the first pulley 14. The rotation is accelerated by the diameter difference between the second pulley 17 and the first pulley 14, reducing the pressing cycle of the crushing nail 11 and avoiding missed crushing. The eccentric part of the surface of the two rotating disks 15 on the same side is rotatably connected to a drive rod 25. The other end of the drive rod 25 is rotatably connected to the side of the displacement drive plate 6. The front surface of the frame 1 is fixedly connected to a rake 19. The rear surface of the frame 1 is provided with a groove 20 extending to its upper and lower surfaces.

[0027] A hydraulic push rod 21 is rotatably connected to the inner wall of the groove 20. Two connecting plates 22 are rotatably connected to the lower surface of the frame 1. A ballast 23 is rotatably connected between the two connecting plates 22. The ballast 23 is raised and lowered by the hydraulic push rod 21. A cross plate 24 is fixedly connected between the two connecting plates 22. The telescopic end of the hydraulic push rod 21 is rotatably connected to the cross plate 24. With the help of the spring 26, the pressure plate 10 can automatically retract when the crushing nail 11 comes into contact with the stone to avoid damage to the crushing nail 11. At the same time, the cooperation of the first pulley 14 and the second pulley 17 can change the slow rotation of the wheel 3 into the rapid vertical movement of the pressure plate 10, without the need for additional drive and reducing energy consumption.

[0028] Working principle: When leveling land, the frame 1 is first connected to a tractor or other vehicle. Then, the tractor's lifting mechanism brings the rake 19 into contact with the ground. The hook-like shape of the rake 19 penetrates the ground for initial leveling and tilling. Simultaneously, when the frame 1 is lowered, the wheels 3 also contact the ground. During movement, the wheels 3 rotate synchronously, driving the drive shaft 13. The drive shaft 13 then synchronously drives the first pulley 14, which, in turn, drives the second pulley 17 through the drive belt 18. Since the diameter of the second pulley 17 is only one-quarter that of the first pulley 14, it also accelerates the rotation of the first pulley 14. The rotation of the first pulley 14 synchronously drives the synchronous shaft 16, which in turn drives the rotating disc 15. The rotation of the rotating disc 15 then drives the drive... The moving rod 25 moves. Since the driving rod 25 is installed at the eccentric position of the rotating disk 15, the driving rod 25 will perform circular motion. Since the movement trajectory of the displacement driving plate 6 is restricted by the first guide rod 4, the displacement driving plate 6 will perform vertical motion. With the help of the movement of the displacement driving plate 6, the spring 26 drives the mounting plate 8 to move, and then the mounting plate 8 indirectly drives the pressure plate 10 and the breaking nail 11 to perform vertical reciprocating motion, completing the breaking of large soil blocks on the ground. At the same time, the hydraulic push rod 21 can also push the horizontal plate 24 to move, thereby driving the connecting plate 22 and the compactor 23 to move and contact the ground, completing the leveling of the ground. When traveling on normal ground, the pressure plate 10 can be pulled up with the electric telescopic rod 9 to avoid contact with the normal road surface. In addition, if the breaking nail 11 comes into contact with a stone during the breaking process, the displacement space provided by the spring 26 can be used to make it retract, reducing the damage to the breaking nail 11.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
