Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a ground pressing wheel. Background Art

In the prior art, the ground wheel is fixed at a certain standard height by a nut to control the depth of rotary tillage and the depth of sowing. On the one hand, the ground wheel with a fixed height cannot adjust the pressure according to the moisture, soil quality, amount of residual straw, etc. of the soil. On the other hand, on uneven ground, the hard contact between the ground wheel with a fixed height and the ground makes it difficult for the ground wheel to always be in contact with the ground and roll.

The preferred technical solution among the many technical solutions provided by the utility model can produce many technical effects as described below.

[0004] To achieve the above-mentioned purpose, the utility model provides a suppressing ground wheel, including a ground wheel, a ground wheel bracket and a suppressor, wherein the ground wheel is connected to one end of the ground wheel bracket through a ground wheel shaft, and the other end of the ground wheel bracket is rotatably connected to a vehicle frame, one end of the suppressor is hingedly connected to the front of the ground wheel bracket, and the other end of the suppressor is connected to the vehicle frame, and the suppressor applies variable pressure to the ground wheel bracket.

[0005] In some embodiments, the packer applies variable pressure to the ground wheel support via a spring.

[0006] In some embodiments, the suppressor includes a suppressor rod, a spring, a fixer and an adjusting nut. The suppressor rod is of a stepped type. The large diameter end of the stepped suppressor rod is connected to the ground wheel bracket, and a threaded section is provided at the small diameter end thereof. The threaded section at the small diameter end passes through the fixer and the adjusting nut is provided at the end of the threaded section. The spring is sleeved on the small diameter end of the suppressor rod between the fixer and the end face of the large diameter end.

[0007] In some embodiments, a shovel board is further included, wherein the shovel board is arranged on a shovel board bracket, and the shovel board bracket is arranged on the ground wheel bracket.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0016] like Figure 1 As shown:

[0017] The utility model provides a suppressing ground wheel, comprising a ground wheel 1, a ground wheel bracket 2 and a suppressor, wherein the ground wheel 1 is connected to one end of the ground wheel bracket 2 through a ground wheel shaft, the other end of the ground wheel bracket 2 is rotatably connected to a vehicle frame 12, one end of the suppressor is hingedly connected to the front of the ground wheel bracket 2, the other end of the suppressor is connected to the vehicle frame 12, and the suppressor applies variable pressure to the ground wheel bracket 2.

[0018] Specifically, the roller is connected to the ground wheel bracket 2, and variable pressure is applied to the ground wheel bracket 2 through the roller. According to the principle of action and reaction force, the buffering force of the ground wheel 1 during operation is different according to the different properties of the ground soil, and the ground reaction force received by the ground wheel 1 is different, and the action force transmitted to the roller is different. The roller applies reaction forces of different pressures according to different action forces, so that the ground wheel 1 can float with the overall rotary tillage seeder under the action of the roller to keep the ground wheel always in contact with the ground and with a certain pressure. This can ensure that the ground wheel is always sown in a driving state, and can also increase the flatness of the ground after rotary tillage sowing. A connecting support plate 9 is provided on the ground wheel bracket 2, and the end of the roller is hinged to the connecting support plate 9 and connected to the ground wheel bracket 2.

The spring 8 is sleeved on the small diameter end 4 of the suppressor rod between the fixer 6 and the end face of the large diameter end.

[0021] Specifically, the pressure of the roller can be adjusted by adjusting the nut 7, so that the pressure can be adjusted according to the moisture, soil quality, amount of residual straw, etc. of the soil, so as to reduce the congestion caused by excessive pressure on the ground wheel 1 after it is fixed. The variable downward force of the roller under the spring 8 allows the ground wheel to always roll in contact with the ground, which can ensure a high accuracy of sowing.

[0022] In some embodiments, a shovel board 11 is further included, and the shovel board 11 is arranged on a shovel board bracket 10, and the shovel board bracket 10 is arranged on the ground wheel bracket 2.
