Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a quick-adjustable ground wheel for an agricultural seeder. Background Technology

[0002] Current methods for adjusting the ground wheel height of seeders typically involve using pin holes or lead screws, or require multiple people to adjust the height. These traditional methods suffer from drawbacks such as inconvenience, inaccurate adjustment, and low efficiency. During spring planting, operators need to frequently adjust the ground wheel height to meet the requirements for sowing depth and plant spacing, depending on the varying soil hardness and moisture content. Therefore, existing ground wheel adjustment methods do not meet the requirements of speed, flexibility, and single-person operation, necessitating a more convenient, efficient, easily adjustable, and stable ground wheel structure. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-adjustment ground wheel for an agricultural seeder, so as to solve one or more problems existing in the prior art, and to make the adjustment of the ground wheel of the seeder more efficient and convenient, which can be operated and adjusted by only one person.

[0004] To achieve the above objectives, the present invention provides the following solution: The present invention provides a quick-adjusting ground wheel for an agricultural seeder, comprising a ground wheel seat, a ground wheel arm, an adjusting assembly, a bearing seat, a ground wheel assembly, a first bolt, a second bolt, a first nut, a third bolt, and a second nut. The ground wheel seat is disposed on the inner side of the ground wheel arm. The ground wheel seat and the ground wheel arm are respectively provided with a first circular hole and a third circular hole. The bearing seat is fixed to the inner side of the ground wheel seat by the first bolt, and the bearing seat is disposed in the first circular hole on the ground wheel seat and the third circular hole on the ground wheel arm. The ground wheel arm can rotate around the axis of the bearing seat. The adjusting assembly is disposed on the inner side of the ground wheel arm by the second bolt and the first nut. The ground wheel assembly is disposed on the ground wheel arm away from the ground wheel seat by the third bolt and the second nut, and is disposed on the inner side of the ground wheel arm.

[0005] Preferably, the ground wheel seat includes two side plates, a hook plate, a reinforcing tube, and a screw sleeve. The two side plates are symmetrically welded to the hook plate, the screw sleeve is symmetrically welded to the hook plate and positioned between the two side plates, and the reinforcing tube is welded between the two side plates.

[0006] The side plate is provided with a first circular hole and a first ratchet tooth, and a first threaded hole is evenly distributed along the axis of the first circular hole. The included angle of the first ratchet tooth is between 40° and 80°.

[0007] Preferably, the bearing housing is a rotating body structure, and the bearing housing is provided with second circular holes evenly distributed on it.

[0008] Preferably, the wheel arm includes two long side plates, a round shaft sleeve, an upper support plate, a support tube, and a lower support plate. The upper support plate is welded between the two long side plates and is located at the top of the two long side plates. The lower support plate is welded to a position away from the upper support plate and is located between the two long side plates. The support tube is welded between the two long side plates and is located between the upper support plate and the lower support plate.

[0009] Preferably, the long side plate is provided with a third circular hole and an arc-shaped recess, and the circular shaft sleeve is welded to the outside of the long side plate and is coaxial with the third circular hole on the long side plate.

[0010] Preferably, the bearing housing passes through the first circular hole on the ground wheel seat and the third circular hole on the ground wheel arm, and is fixed in the first threaded hole on the ground wheel seat by the first bolt passing through the second circular hole, so that the ground wheel arm can rotate on the bearing housing.

[0011] Preferably, the adjustment assembly includes an adjustment plate, tension springs, a fixed shaft, an adjustable pin, a bushing, and a fourth bolt. The adjustment plate has a fourth circular hole at one end and a long groove at the other end, with a second ratchet near the fourth circular hole. The fixed shaft has symmetrically arranged circular grooves and second threaded holes at both ends. The fixed shaft is detachably fixed between the two adjustment plates by the fourth bolt and locked through the second threaded holes. The adjustable pin has symmetrically arranged circular grooves identical to those on the fixed shaft. One end of each of the two tension springs is located in the circular groove on the fixed shaft, and the other end is located in the circular groove on the adjustable pin. The adjustable pin is located in the long groove on the adjustment plate and can slide along the long groove. The bushing is located in the fourth circular hole of the adjustment plate, and the length of the bushing is greater than the thickness of the adjustment plate, allowing the adjustment plate to rotate on the bushing.

[0012] Preferably, the adjustment assembly is detachably mounted between the ground wheel arms via a second bolt and a first nut. The adjustable pin is engaged in an arc-shaped recess on the long side plate under the tension of a tension spring, while the first ratchet on the adjustment plate meshes with the second ratchet on the side plate.

[0013] When an external force is applied, pulling the adjustable pin will pull it out of the arc-shaped recess on the long side plate. Under the action of gravity, the first and second ratchet teeth of the ground wheel arm will separate, thereby adjusting the height of the ground wheel by lifting the ground wheel arm by a single person.

[0014] The present invention achieves the following beneficial technical effects compared to the prior art:

[0015] 1. This utility model provides a method for quickly adjusting the ground wheel of a seeder. By pulling the adjusting pin, the operator can flexibly adjust the height of the ground wheel. The operation is simple, requires no additional personnel assistance, and the adjustment process is quick and easy, greatly improving work efficiency.

[0016] 2. This utility model provides a method for quickly adjusting the ground wheel of a seeder. The adjustable pin shaft is pulled by a tension spring to control the interaction of the ratchet teeth, which ensures the stability of the ground wheel during use, avoids the ground wheel from becoming loose after adjustment, and ensures safe use.

[0017] 3. The present invention provides a method for quickly adjusting the ground wheel of a seeder. The modified structure eliminates the need for a complex hydraulic system or multiple people to work together, thereby reducing production and usage costs and simplifying maintenance.
