The utility model has a simple structure, and under the control of the main wheel and the secondary wheel, the agricultural equipment can be freely driven in the paddy field, the secondary wheel is light and easy to disassemble, and the agricultural machinery does not need to be equipped with the secondary wheel when cultivating in the dry field, so the utility model is applicable to both paddy fields and dry land.

Description

Agricultural machinery wheel

Technical Field

The utility model relates to the field of vehicle accessories, in particular to an agricultural machinery wheel.

Background

Agriculture is an industry that obtains products by artificial cultivation by utilizing growth and development rules of animals and plants. Agriculture belongs to a first industry, and the science of studying agriculture is agronomy. The agricultural labor object is living animals and plants, and the obtained product is the animals and plants. Agriculture is a basic industry that supports the construction and development of national economy.

The agricultural machinery works in paddy fields mainly blocked by water in the fields or deep or shallow water and suddenly-insufficient puddles, so that the cultivation of the agricultural machinery in the paddy fields is particularly difficult. Many techniques exist that can solve the problem of sinking agricultural machinery into puddles by changing the configuration of the wheels, but are still not perfect.

In view of the above, the present utility model provides an agricultural machine wheel to adapt to the normal operation of agricultural vehicles in different environments.

Disclosure of utility model

The present utility model is directed to an agricultural machine wheel, which solves the above-mentioned problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: an agricultural machine wheel comprising two parts, a main wheel and an auxiliary wheel, connected with an axle of a vehicle, comprising: the main wheel tire is a rubber tire with a plurality of trapezoid gear teeth on the circumference;

The auxiliary wheel and the main wheel are connected with the central shaft of the main wheel through a central sleeve on the auxiliary wheel, the main wheel is connected with the wheel shaft of the vehicle through the central shaft, the auxiliary wheel rotates at a high speed when the vehicle works in a paddy field, the vehicle can be prevented from sinking into a puddle, the central shaft penetrates through the axes of the two wheels, and the wheels are fixed on the shafts through nuts or fasteners. In this way, the synchronous rotation and mutual cooperation of the two wheels can be realized, so that the two wheels can operate as a whole;

the auxiliary wheel consists of a gear ring and a central sleeve, the diameter of the gear ring is the same as that of the main wheel, and the central sleeve is used for connecting the main wheel and the auxiliary wheel.

Preferably, the spoke is in a three-leaf sector shape, the structure is simple, and clay is not easy to adhere during operation.

Preferably, the tyre of the main wheel and the rim of the auxiliary wheel are provided with trapezoid gear teeth, and the trapezoid gear teeth have a certain tooth height, so that the phenomenon that the trapezoid gear teeth are deeply sunk in two places of paddy and dry land is avoided.

Preferably, the main wheel and the auxiliary wheel are connected with the central sleeve of the auxiliary wheel through the central shaft of the hub part of the main wheel, can be easily disassembled, and are assembled stably.

Preferably, the main wheel tire is a rubber tire with good ground grabbing capability, slipping can be avoided, the running process of the wheels is kept stable, in addition, the whole rubber tire can play a role in buffering and stably run, jolt is not easy, and the transport efficiency of two lands of paddy field and dry land is improved.

Preferably, the utility model has simple structure and can work in both paddy fields and dry lands.

The utility model has the beneficial effects that: the utility model has simple structure, adopts simple mechanical assembly, and assembles the agricultural wheels with the auxiliary wheels on the side surface so as to adapt to the working requirement of the agricultural vehicle for operation in paddy fields and prevent the wheels from sinking into puddles. Meanwhile, the auxiliary wheel is convenient to assemble and disassemble, and the dual-purpose function of the wheel for paddy fields and dry lands is achieved.

Detailed Description

The utility model provides a wheel which has higher assembly strength and structural reliability, is safer and more stable in the installation and running process and is suitable for paddy fields and dry lands.

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1 to 4, an agricultural machine wheel comprises a main wheel and an auxiliary wheel, wherein the main wheel and the auxiliary wheel are connected with a central sleeve of the auxiliary wheel through a central shaft of a hub part of the main wheel, and the auxiliary wheel can be easily disassembled when not in use; the main wheel tyre and the auxiliary wheel gear ring are provided with trapezoid gear teeth, namely trapezoid surfaces are formed from two sides of the wheel, and the supporting strength is high.

When the field is operated, whether the auxiliary wheel is necessary to be used is judged according to the paddy-upland condition of the operation zone, and if the field is operated in a paddy field, the auxiliary wheel is required to be assembled so as to avoid deep sinking of the wheel into the puddle.

The foregoing is merely illustrative of specific embodiments of the present utility model, and the scope of the utility model is not limited thereto, but any changes or substitutions that do not undergo the inventive effort should be construed as falling within the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
