[0002] During the planting process of winter wheat, different soil moisture conditions and different sowing times will lead to obvious differences in the growth of winter wheat. Different situations may occur, such as weak seedlings, vigorous growth and false vigorous growth. Therefore, different rollers are needed to cope with different wheat field pressing needs.

[0022] The counterweight 8 is T-shaped, so that the counterweight 8 maintains a good dynamic balance during the rotation process and reduces abnormal noise and vibration.

[0023] The ends of the pressing rollers 3 are each provided with a plurality of air holes 3001 in a circular array.

[0024] The diameter of the pores 3001 on the pressing roller 3 gradually decreases from the middle to the periphery, so as to reduce the situation where impurities enter the pressing roller 3 during the pressing process.

[0025] The working steps of this embodiment are: Existing suppressing equipment is generally a tractor-towed suppressor, or a suppressing wheel is added to the tractor, which moves on the wheat field to suppress the wheat seedlings. However, different soil moisture conditions and different sowing times lead to obvious differences in the growth of winter wheat, resulting in different situations such as weak seedlings, vigorous growth and false vigorous growth. Therefore, different suppressors are needed to cope with different wheat field suppression needs. However, it is necessary to purchase multiple suppressors, which consumes a lot of money and increases production costs. It also takes a lot of space to store the suppressors and reduce rust damage to the suppressors. Therefore, the suppressing strength needs to be adjusted according to different winter wheat growth conditions. When suppressing the vigorous winter wheat, the two electric actuators Ⅰ9 are controlled to extend, and the two ends of the pull rope Ⅰ11 are moved downward synchronously. All the counterweights 8 connected to the connecting rod 8001 fall downward together under the action of gravity, and synchronously drive the corresponding spring telescopic rods 7 to extend. long, then control to start two DD motors 5, the rotating part of DD motor 5 drives the rotating rod 6 to rotate, and synchronously drives the spring telescopic rod 7 and the corresponding parts thereon to rotate, and the rotary joint 10 also rotates with the rotation of the pull rope Ⅰ11, wherein the friction between the pull rope Ⅰ11 and the guide wheel Ⅰ12 is reduced by applying lubricating oil on the guide wheel Ⅰ12. At this time, the operator starts the seedling pressing and strengthening machine to move on the wheat field, so that the pressing roller 3 rolls on the wheat seedlings, and the wheat seedlings are pressed by the weight of the vehicle body itself. At this time, the eccentrically rotating T-shaped counterweight hammer 8 added in the pressing roller 3 is used to increase the pressing force of the pressing roller 3 on the wheat seedlings, thereby applying greater pressure on the vigorously growing wheat seedlings, uniformly pressing the wheat seedlings, inhibiting the excessive growth of the ground part of the wheat seedlings, promoting the growth of the underground part of the wheat, ensuring the safe wintering of the wheat, effectively reducing the number of pressing times on the wheat seedlings, reducing the damage to the wheat seedlings, and ensuring the normal tillering and ear formation of wheat in the coming year.

[0026] Before suppressing the falsely vigorous wheat, since the stems of the falsely vigorous wheat seedlings are weak, too much suppression force may easily damage the wheat seedlings and affect the tillering of wheat in the next year. Therefore, it is necessary to carefully analyze the specific conditions of the wheat seedlings and the soil conditions to determine the suppression force for the wheat. Then, the winter wheat is suppressed. After the required suppression force is determined, the two controlled electric actuators Ⅰ9 shrink to the corresponding length, synchronously drive the rotary joint 10 to pull the two ends of the pull rope Ⅰ11 upward, thereby driving the guide wheel Ⅲ14 to move upward through the pull rope Ⅰ11, and then the winter wheat is suppressed. This causes the spring telescopic rod 7 to contract, driving the corresponding counterweight 8 to move upward, thereby reducing the radius of the eccentric rotation of the counterweight 8. The force generated by the eccentric rotation of the counterweight 8 is also reduced, thereby reducing the overall pressing force of the pressing roller 3 on the wheat seedlings and reducing damage to the wheat seedlings. During the pressing process of the wheat seedlings, the adhesion of wheat seedling debris on the pressing roller 3 is monitored by the visual sensor on the rotating bracket 2, and the electric actuator Ⅰ9 is controlled to contract, thereby adjusting the pressing force of the pressing roller 3 in real time, reducing damage to the wheat seedlings and evenly pressing the wheat seedlings.

[0027] In the treatment of weak seedlings, the reasons for the appearance of weak seedlings are first analyzed, and then the soil moisture conditions are analyzed, and finally it is determined whether it is suitable for suppression. If suppression operation is required, the two DD motors 5 are controlled to be turned off, so that the rotating rod 6 and the corresponding parts thereon no longer rotate. At this time, the pressing force of the pressing roller 3 is the smallest, and then the visual sensor on the rotating bracket 2 is used to monitor the adhesion of wheat seedling debris on the pressing roller 3. If there is still wheat seedling debris adhered to the pressing roller 3, the moving speed of the seedling strengthening machine body 1 is increased by controlling to indirectly reduce the pressing force applied to the wheat seedlings, thereby reducing the damage to the wheat seedlings. The wheat seedlings can also be evenly suppressed. After the suppression is completed, the wheat seedling debris on the pressing roller 3 can be manually cleaned.

[0028] Considering that the pressing roller 3 is in continuous contact and friction with the wheat seedlings during the pressing operation, the temperature of the pressing roller 3 gradually increases, and there are also components such as the spring telescopic rod 7 and the counterweight hammer 8 rotating inside the pressing roller 3, which generate heat due to the friction between the components and the air, causing the temperature of the pressing roller 3 to increase. The high temperature on the pressing roller 3 may damage the wheat seedlings, so an air hole 3001 is provided on the pressing roller 3 to dissipate heat inside the pressing roller 3. When the spring telescopic rod 7 and the counterweight hammer 8 rotate inside the pressing roller 3, it also plays a role The fan blades drive the air flow in the pressing roller 3, and then discharge the heat in the pressing roller 3 to the outside through the air holes 3001. In order to reduce the splashing of dirt and gravel impurities in the wheat field and the situation of entering the pressing roller 3 through the air holes 3001, the air holes 3001 are set to have a trend of decreasing diameter from the middle to the surrounding areas. In this way, not only can the heat dissipation requirements be still met, but the air holes 3001 near the edge of the pressing roller 3 are also smaller, making it difficult for dirt and gravel impurities to pass through, thereby reducing the difficulty of cleaning and maintenance of the seedling pressing and strengthening machine.

[0029] In summary, by controlling the extension and retraction of the electric actuator Ⅰ9 and then adjusting the eccentric rotation radius of the counterweight hammer 8, it is possible to achieve fine adjustment of the pressing force, ensure the best pressing effect, uniformly press wheat of different growth rates, reduce damage to wheat seedlings, inhibit the growth of the above-ground part of wheat, promote the growth of the underground part of wheat, compact the soil, reduce water loss, maintain soil moisture, ensure the safe wintering of wheat, and promote tillering and ear formation of wheat in the coming year.

[0030] Second embodiment: Based on the first embodiment, Figure 1 , Figure 6 and Figure 7 As shown, it also includes a spring 15, an electric actuator II 16, a pull rope II 17 and a chuck 18; the rotating bracket 2 is bolted to two springs 15 distributed front and back; the spring 15 is fixed at one end and movable at the other end; the rotating bracket 2 is equipped with two electric actuators II 16 distributed front and back; the electric actuator II 16 is an electric push rod; the telescopic part of each electric actuator II 16 is in contact with the movable end of a spring 15; each spring 15 is provided with a straight groove II 1501; the rotating bracket 2 is provided with two straight grooves I 2001 distributed front and back; a pull rope II 17 is passed through the two straight grooves I 2001 in turn; the pull rope II 17 is in contact with the pressure roller 3; a chuck 18 is fixedly connected to each end of the pull rope II 17; each chuck 18 is in contact with a spring 15.

[0031] The telescopic part of the electric actuator II 16 is a wear-resistant arc-shaped contact head, which is used to reduce the friction between the telescopic part of the electric actuator II 16 and the reed 15 and increase the service life of the contact head of the telescopic part of the electric actuator II 16.

[0032] The side of the reed 15 away from the electric actuator Ⅰ9 is inclined downward.

[0033] The contact position between the chuck 18 and the reed 15 is coated with a wear-resistant coating to reduce the wear of the chuck 18 and the reed 15 .

[0034] The working steps of this embodiment are: In the above embodiment, due to different soil moisture conditions, the growth of wheat is different, and it is impossible to completely rely on the preset compaction intensity scheme to perform a uniform compaction operation on the wheat. Therefore, during the compaction operation, if a large amount of wheat seedling debris adheres to the outer surface of the compaction roller 3, it indicates that the compaction is too large. The friction between the compaction roller 3 and the wheat seedlings causes the wheat seedlings to be broken and adhere to the compaction roller 3. Therefore, it is necessary to adjust the compaction intensity in real time to reduce the damage to the wheat seedlings. It should also be considered that when the surface of the compaction roller 3 is a smooth surface, it can be The wheat is evenly pressed. If there are wheat seedling debris adhering to the surface of the pressing roller 3, the pressing force of the pressing roller 3 on the wheat seedling is uneven, which will increase the friction between the pressing roller 3 and the wheat seedling, making it easier for the wheat seedling to be broken, causing serious damage to the wheat seedling. Therefore, after adjusting the pressing force, the visual sensor on the rotating bracket 2 monitors the adhesion of wheat seedling debris on the pressing roller 3, controls the extension of the two electric actuators Ⅱ16, and the telescopic part of the electric actuator Ⅱ16 presses against the active end of the spring leaf 15, so that the spring leaf 15 bends and deforms, and at the same time makes the pull rope Ⅱ17 is stretched straight, and the pull rope Ⅱ17 also drives the chuck 18 to move toward the fixed end of the spring sheet 15 along with the spring sheet 15. The stretched pull rope Ⅱ17 also moves toward the direction of the pressing roller 3 until the pull rope Ⅱ17 is in close contact with the pressing roller 3, and the two electric actuators Ⅱ16 are controlled to stop. When the pressing roller 3 is rolling, the pull rope Ⅱ17 in close contact with it scrapes off the wheat seedling debris on the surface of the pressing roller 3, thereby cleaning the pressing roller 3. The wheat seedling debris falls directly back into the wheat field and becomes nutrients for the wheat field. If the pressing roller 3 has been cleaned, the two electric actuators are controlled to stop. The actuator Ⅱ16 contracts and simultaneously restores the reed 15. At this time, the reed 15 is tilted. When the reed 15 is restored, the reed 15 no longer presses the pull rope Ⅱ17 on the pressing roller 3. Under the action of gravity, the pull rope Ⅱ17 moves to the side away from the pressing roller 3. In this way, the pull rope Ⅱ17 can not only clean the pressing roller 3, but also automatically move away from the pressing roller 3 after cleaning, thereby avoiding long-term friction contact between the pressing roller 3 and the pull rope Ⅱ17, which causes wear of the pull rope Ⅱ17 and the pressing roller 3, and prolongs the service life of the pull rope Ⅱ17.
