Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery parts technology, specifically to a vehicle-mounted bracket for convenient wheel replacement. Background Technology

[0002] With the advancement of agricultural modernization, agricultural machinery and equipment are becoming increasingly widespread. Looking at the evolution of rotary tillers, they have gradually shifted from the initial hand-held mini-tillers to more efficient, ride-on rotary tillers that reduce labor. Ride-on rotary tillers operate on the same principle as mini-tillers; tires or blades can be mounted on the front or rear axle. Tires are used when traveling on roads, while blades are used for tilling.

[0003] However, riding rotary tillers are larger and heavier than mini tillers, so changing the wheels is naturally not as convenient as with mini tillers. The best way is to use external tools to lift the whole machine off the ground, making it easier to change the wheels.

[0004] Current models typically use external tools for changing wheel fittings, such as hydraulic jacks, mechanical jacks, lifting platforms, and support frames. Other methods involve manually lifting the entire machine or using winches to pull it up. These methods are generally cumbersome or physically demanding for users, and these tools are not highly adaptable to different operating environments. Utility Model Content

[0005] I. Technical problems to be solved

[0006] This utility model addresses the shortcomings of existing technologies by proposing a vehicle-mounted support that facilitates wheel replacement. When wheel replacement is required, only one person is needed to lift the agricultural machinery using the vehicle-mounted support, which greatly reduces the difficulty and workload of wheel replacement.

[0007] II. Specific Technical Solutions

[0008] A vehicle-mounted bracket for easy wheel replacement includes a mounting base and a support bracket. One end of the mounting base is used for overall mounting of the vehicle-mounted bracket. The other end of the mounting base is provided with a mounting hole, and one end of the support bracket is rotatably connected to the mounting base through the mounting hole. The other end of the support bracket is a support end, which extends to the left and right sides or either left or right side to form an extended support portion.

[0009] Implementation principle and working principle:

[0010] In practical use, this solution involves mounting the vehicle-mounted bracket onto the tiller using the mounting base. When it is necessary to change the wheels, place the support end of the support bracket on the ground, then start the tiller. The tiller will move forward under its own power, and the support bracket will support the machine body. Then, stop the power supply to easily and conveniently change the tiller's wheels. The presence of the extended support section makes the tiller or agricultural machinery more stable.

[0011] Preferably, the mounting base is provided with a long sliding hole, which is located entirely below the mounting hole, and one end of the long sliding hole is connected to the bottom of the mounting hole. The end of the support bracket located inside the mounting hole can slide along the mounting hole and the long sliding hole.

[0012] Preferably, a locking mechanism is provided on the support bracket or mounting base, the locking mechanism being used to fix the support bracket on the mounting base.

[0013] Preferably, the locking mechanism is a quick-adjusting clamp, which includes a base, a rotating handle rotatably connected to the base, a hook on the rotating handle, and a lug on the mounting base.

[0014] Preferably, the support bracket is provided with support rods on both sides, and the extended support part is a support rod provided at the bottom of the support rod;

[0015] Preferably, the free end of the support rod is also provided with an external mounting bracket for installing external components.

[0016] Preferably, the support bracket further includes a connecting plate, the two ends of which are fixedly connected to two support rods respectively.

[0017] Preferably, the connecting plate is also provided with damping teeth on the side away from the mounting hole.

[0018] Preferably, the support bracket is provided with a limiting component, which is located on the side of the support bracket closer to the mounting base.

[0019] The beneficial effects of this utility model are as follows:

[0020] The integrated, lockable and slidable quick-release structure allows one person to easily use the vehicle-mounted bracket to conveniently change the rotary tiller's wheels. Since it is installed on the vehicle, it can be retracted when not in use, which does not affect rotary tillage and also avoids the situation where the wheels cannot be changed due to forgetting to bring the tools.

[0021] An external mounting bracket can be installed on the support frame, which can serve as a tool attachment point during transportation, eliminating the need to carry a separate tool hanger and reducing the number of tools that the operator needs to carry during transportation.

[0022] Based on actual usage, a ground contact damping tooth structure is designed to make lifting the entire machine easier.

[0023] The extended support increases the stability of the entire machine after lifting, improving its safety and reliability. Attached Figure Description

Detailed Implementation

[0031] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] Example 1, such as Figure 1-4 As shown:

[0033] A vehicle-mounted bracket that facilitates wheel replacement, such as Figure 1 Installed at the front of the mini-tiller body, it includes a mounting base 100 and a support bracket 200. The right end of the mounting base 100 can be bolted to the mini-tiller as a whole. A mounting hole 101 is provided at the bottom left end of the mounting base 100. One end of the support bracket 200 is rotatably connected to the mounting hole 101 via a shaft. The bottom end of the support bracket 200 is the support end 201. Figure 4 The support end 201 extends to the left and right sides or either left or right side to form an extended support part 202. In this embodiment, the extended support part 202 is specifically located on the upper side of the left end of the support bracket 200.

[0034] The implementation principle of the main plan is:

[0035] In practical use, the mounting bracket is installed on the mini-tiller via the mounting base 100. When the wheels need to be replaced, the support end 201 of the support bracket 200 is placed on the ground, and then the mini-tiller is started. Driven by its own power, the mini-tiller moves forward. The presence of the support bracket 200 will support the machine body. Then, the power supply can be stopped to easily and conveniently replace the mini-tiller's wheels. In particular, the presence of the extended support part 200 makes the support of the mini-tiller or agricultural machinery more stable.

[0036] In implementation, the mounting base 100 has a horizontally oriented elongated sliding hole 102, which is located below the mounting hole 101. The left end of the elongated sliding hole 102 is connected to the bottom of the mounting hole 101. The upper end of the support bracket 200 can slide along the mounting hole 100 and the elongated sliding hole 102. A locking mechanism 3 is provided on the support bracket 200 or the mounting base 100. The locking mechanism 3 can fix the support bracket 200 on the mounting base 100. The support bracket 200 can slide along the elongated sliding hole 102. When the support bracket 200 slides to the rightmost end of the elongated sliding hole 102, it is fixed by the locking mechanism 3. This can greatly reduce the footprint of the support bracket 200.

[0037] In specific implementation, the locking mechanism 3 of this solution is a quick-adjusting clamp, which includes a base 301. The base 301 is specifically installed in the lower middle part of the support bracket 200. This can better improve stability and reduce the footprint when locking. A rotating handle 302 is rotatably connected to the base 301, and a hook 303 is provided on the rotating handle 302. The hanging ear 304 of the quick-adjusting clamp is provided on the mounting base 100. The fixing, unlocking and locking of the support bracket 200 can be realized through the cooperation of the hook 303 and the hanging ear 304, which is simple and convenient.

[0038] In implementation, the two sides of the support bracket 200 are support rods 203, and the extended support part 202 is a support rod set at the bottom of the support rod 203. In this embodiment, the support rod is formed by folding the bottom end or left end of the support rod 203. The free end of the support rod is also welded with an external mounting bracket 204 for installing external components. Specifically, the external components are wheels or other parts. The advantage of this arrangement is that the external components are more convenient to carry.

[0039] In implementation, the support bracket 200 also includes a connecting plate 205. Specifically, the two ends of the connecting plate 205 are fixedly connected to two support rods respectively. A damping tooth 206 is also provided on the side of the connecting plate 205 away from the mounting hole 101. In specific implementation, multiple damping teeth 206 are provided at the bottom of the connecting plate 205, and the damping teeth 206 are spaced apart in the length direction of the connecting plate 205. This allows the support bracket 200 to contact the ground first when it is lowered, which can reduce the initial contact angle between the support bracket 200 and the ground, increase the resistance between the support bracket 201 and the ground when it is raised, and make the support quicker and more convenient. Example

[0040] like Figure 5 The difference between this embodiment and the existing embodiment 1 is that this solution provides a limiting component 4 on the support bracket 200. In this embodiment, the limiting component 4 is specifically a limiting stop bar, which is specifically welded to the upper side of the support bracket 200. When the support bracket 200 is rotated to the position, the limiting stop bar will support between the support bracket 200 and the mounting base 100, achieving the effect of rotation limiting and improving safety.

[0041] Furthermore, to further enhance safety performance, a sensing component is provided on the limit component 4. Specifically, the sensing component can be a pressure sensor or an angle sensor. An alarm component that works in conjunction with the sensing component is also provided on the moving mechanism. Specifically, the alarm component can be a buzzer. When the sensing component detects that the support bracket has rotated to the correct position, the alarm component will sound an alarm to prevent the moving mechanism from rotating excessively and causing danger.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims.
