Description

Technical Field

[0001] This invention relates to agricultural machinery, and in particular to a depth-limiting wheel device suitable for agricultural machinery used in saline-alkali land. Background Technology

[0002] Modern agricultural machinery often suffers operational problems due to uneven soil surfaces. Uneven ground can cause the machinery's contact parts to penetrate the soil too deeply or too shallowly. Furthermore, in saline-alkali soils, the presence of numerous clods makes the terrain rugged. Especially during rainy weather, the muddy soil can cause the depth-limiting wheels of agricultural machinery to sink into the soil, and the muddy material can stick to the wheels, making the machinery even more difficult to operate. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and to propose a depth limiting wheel device suitable for agricultural machinery in saline-alkali land. This device can adjust the body posture of the agricultural machinery connected to it at any time according to the undulation of the ground, and enable the depth limiting wheel to pass normally through muddy and rugged saline-alkali land.

[0004] The technical solution of this invention is: a depth-limiting wheel device suitable for agricultural machinery in saline-alkali land, comprising:

[0005] The buffer spring and the depth-limiting wheel are connected to the spring above them via a wheel support plate;

[0006] Two depth-limiting wheels are rotatably connected to wheel support plates. Several figure-eight contact plates are fixed at intervals along the annular outer surface of the depth-limiting wheels, and the figure-eight contact plates fixed on the two depth-limiting wheels are arranged in opposite directions.

[0007] In this utility model, the wheel support plate includes wheel plates located on both sides and a support plate fixed to the top of the wheel plates;

[0008] Two depth-limiting wheels are set between two wheel plates, and the top surface of the support plate is connected to the connecting bolt above it by a buffer spring.

[0009] The two depth-limiting wheels are connected to the wheel plate through the same rotating shaft, and the two depth-limiting wheels are connected to the rotating shaft through bearings respectively.

[0010] The depth-limiting wheel includes a hub and a wheel plate fixed to the annular outer surface of the hub;

[0011] A support ring is fixed in the center of the wheel plate, and several connecting platforms are set at intervals along the circumference of the support ring. Each connecting platform is fixed with a figure-eight contact plate.

[0012] The figure-eight contact plate includes two intersecting flat plates, which are set at an angle to each other;

[0013] The orientation of the figure-eight contact plates on the same depth limiting wheel is the same, while the orientation of the figure-eight contact plates between two depth limiting wheels is opposite.

[0014] The beneficial effects of this invention are:

[0015] (1) By setting a buffer spring, it can play a role in conforming and buffering, avoiding excessive shaking of saline-alkali agricultural machinery connected to the device on rugged ground, so that the machinery can better adjust the posture of the machine body according to the undulation of the ground during the movement of the machinery.

[0016] (2) By setting two independently rotating depth limiting wheels and setting oppositely oriented figure-eight soil contact plates on the outer surfaces of the two depth limiting wheels, when the device passes through muddy and rugged saline-alkali ground, the two depth limiting wheels have different rotation speeds according to the different contact surfaces of the depth limiting wheels, and the two oppositely oriented figure-eight soil contact plates can squeeze out the soil, preventing the depth limiting wheels from collapsing into the saline-alkali ground, and ensuring that the depth limiting wheel device can pass through muddy and rugged saline-alkali ground smoothly.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Specific details are set forth in the following description to provide a full understanding of the invention. However, the invention can be practiced in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 As shown, the depth limiting wheel device for agricultural machinery in saline-alkali land according to the present invention includes two depth limiting wheels, which are rotatably connected to the wheel support plate 3 respectively.

[0024] In this embodiment, the wheel support plate includes wheel plates on both sides and a support plate fixed to the top of the wheel plates. There is a certain gap between the two wheel plates, and the two depth-limiting wheels are located between the two wheel plates. The support plate is connected to the connecting bolt 1 above it via a buffer spring 1. The connecting bolt 1 enables the connection between the device and the saline-alkali land agricultural machinery. By setting the buffer spring 2, the saline-alkali land agricultural machinery connected to the device can adjust the posture of the entire machine and the soil-excavation angle according to the undulation of the ground, thereby achieving a better depth-limiting function.

[0025] In this embodiment, the two depth-limiting wheels are a first depth-limiting wheel 4 and a second depth-limiting wheel 5, which are arranged side by side and positioned between two wheel plates. The first depth-limiting wheel 4 and the second depth-limiting wheel 5 are connected to the wheel plates on both sides via a rotating shaft 12, which passes sequentially through one wheel plate, the first depth-limiting wheel 4, the second depth-limiting wheel 5, and the wheel plate on the other side. The first depth-limiting wheel 4 and the second depth-limiting wheel 5 are respectively connected to the rotating shaft 12 via bearings, thus allowing each depth-limiting wheel to rotate independently.

[0026] The depth-limiting wheel includes a hub 7 and a wheel surface 8 fixed to the annular outer side of the hub. Several figure-eight contact plates 6 are fixed at intervals along the annular outer circumference of the wheel surface. Each figure-eight contact plate consists of two intersecting flat plates at a certain angle, forming a figure-eight shape. The figure-eight contact plates can play a certain role in breaking up the soil.

[0027] A support ring 11 is fixed at the center of the annular wheel surface. The support ring 11 is arranged along the annular outer surface of the wheel surface, thus the support ring is circular. Several connecting platforms 10 are fixed at intervals along the circumference of the support ring 11. Each connecting platform 10 is fixed with a figure-eight contact plate 6. With the above structure, several figure-eight contact plates are fixedly arranged on the annular outer surface of the depth-limiting wheel.

[0028] The direction of the figure-eight contact plates on adjacent depth limiting wheels is opposite. In this embodiment, the direction of the figure-eight contact plates on the first depth limiting wheel and the second depth limiting wheel is opposite, that is, they are set in opposite directions.

[0029] When the depth-limiting wheel device is operating on leveled ground, the two depth-limiting wheels function as a single integral wheel, serving to limit depth and provide guidance. When encountering uneven ground, the buffer springs provide cushioning and conformity. When encountering muddy or rugged ground, the two depth-limiting wheels rotate at different speeds, and the opposing figure-eight contact plates squeeze out the mud, ensuring the depth-limiting wheels can smoothly traverse muddy and rugged terrain and preventing them from collapsing.

[0030] The depth-limiting wheel device for agricultural machinery in saline-alkali land provided by this invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention. It should be noted that for those skilled in the art, several improvements and modifications can be made to this invention without departing from the principles of this invention, and these improvements and modifications also fall within the protection scope of the claims of this invention. The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
