Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, and particularly relates to a ground wheel device of a seeder. Background Art

[0002] Today, with the rapid development of agricultural mechanization, as one of the important agricultural machinery, the performance and efficiency of soybean seeders directly affect the yield and quality of crops. During the soybean seeding process, the ground wheels of the seeder, as key components, not only bear the weight of the whole machine but also are responsible for walking in the field and driving the seeding mechanism to work. However, when operating in wet or muddy fields, the ground wheels are extremely likely to adhere to a large amount of soil, which not only increases the rotational resistance of the ground wheels, reduces the seeding efficiency, but also may cause the ground wheels to jam due to excessive soil accumulation, affecting the normal operation of the seeder.

[0003] The traditional designs of ground wheels for soybean seeders often neglect the problem of soil cleaning or only adopt simple fixed mud scraping devices, which have obvious deficiencies in terms of cleaning effect, adaptability, and adjustability. For example, the fixed mud scraping devices cannot be flexibly adjusted according to tire wear or different operating environments, resulting in unsatisfactory cleaning effects. Even, they may become ineffective due to the excessive gap between the mud scraping plate and the tire and need to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a ground wheel device for a seeder that can reduce soil residue on the wheels, keep the wheels clean and maintain their grip, aiming at the above problems.

[0005] To achieve the above purpose, the utility model discloses a ground wheel device of a seeder, which includes a wheel frame. A wheel is rotatably installed on the wheel frame. The wheel includes a hub, spokes, and a tire. Its structural feature is that: mud scraping seats are installed on the wheel frame, located on the left and right sides of the hub. Mud scraping plates are installed on the mud scraping seats, located outside the tire. The inner side of the mud scraping seat is close to the hub and has a shape adapted to the hub. The inner side of the mud scraping plate is close to the tire and has a shape adapted to the tire.

[0006] After adopting the above structure, it can ensure that when the seeder operates in complex terrains, it can effectively remove the soil adhering to the tire and the hub, reduce the increase in friction and mechanical failures caused by soil accumulation. And it can improve the cleaning efficiency, reduce soil residue, and keep the wheels clean and maintain their grip.

[0007] To facilitate the removal of hardened mud on the tire, multiple plow blades are provided on the mud scraping plate. The multiple plow blades are spaced from each other. The plow blade includes a blade edge that extends towards the tire. A blade seat is provided at the rear of the blade edge and is fixedly installed on the mud scraping plate. Installing plow blades on the mud scraping plate can scrape off the dry and hard mud on the tire through the plow blades. The multiple plow blades are spaced from each other, making it easier to cut the hardened mud.

[0008] A length adjustment mechanism for adjusting the extension length of the mud scraping plate is installed on the mud scraping seat and the mud scraping plate. Through the length adjustment mechanism, the extension length of the mud scraping plate can be flexibly adjusted to adapt to different working environments and tire wear conditions. It can enhance the adaptability and flexibility of the equipment, extend the service life, and reduce the problem of mud scraping failure caused by fixed design.

[0009] The length adjustment mechanism includes a threaded hole opened on the mud scraping seat, an adjustment hole is opened at the rear end of the mud scraping plate, and an adjustment bolt is installed on the mud scraping plate and passes through the adjustment hole and is tightened in the threaded hole. Precise adjustment can be made according to different sizes of tires and the degree of tire wear, so as to meet different requirements.

[0010] The adjustment hole is an oblong hole, and the oblong hole design allows the mud scraping plate to have a certain lateral movement space during adjustment, increasing the flexibility of adjustment.

[0011] There are two threaded holes, and two corresponding adjustment bolts are provided, making the installation of the mud scraping plate more firm and reliable.

[0012] The mud scraping seat includes two left and right half seats, the half seats extend backward, and the front ends of the half seats are fixedly installed on the wheel frame. It is convenient for installation and maintenance, reduces the maintenance difficulty and the cost of individual replacement.

[0013] The middle part of the half seat is recessed towards the spoke of the ground wheel, and the rear end of the half seat extends outward along the outer edge of the wheel hub. It ensures the close fit between the mud scraping seat and the wheel hub, improves the mud scraping effect, and reduces the entry of soil into the gap between the mud scraping seat and the wheel hub.

[0014] The front end of the half seat is fixedly installed on the wheel frame through a positioning bolt. The connection method is simple and reliable, easy to disassemble and replace. It ensures the stability of the mud scraping seat during operation and reduces loosening or falling off caused by vibration.

[0015] A wheel axle is fixedly installed on the wheel hub, a bearing is installed on the wheel frame, and the wheel axle is connected to the bearing. It extends the service life of the wheel axle and the bearing, reduces energy consumption, and improves the overall performance.

[0016] In summary, the beneficial effects of the present utility model are as follows: An adjustable mud scraping device is added to the ground wheel, effectively cleaning the soil on the outer side of the wheel hub and the tire. Through the length adjustment mechanism, the extension length of the mud scraping plate can be adjusted according to actual needs to adapt to different tire wear degrees and working environments, thereby improving the cleaning efficiency and adaptability of the ground wheel of the soybean seeder, effectively solving the problem that the traditional ground wheel is easy to adhere to soil during operation in muddy fields, and improving the seeding efficiency and adaptability.
