Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery accessories, and in particular to a vehicle-mounted bracket and a method for conveniently replacing wheels. Background Art

[0002] With the advancement of agricultural modernization, agricultural machinery and equipment are becoming more and more popular. From the evolution of rotary tillers, it has gradually shifted from the initial walk-behind micro-tillage machine to a ride-on rotary tillage machine that reduces labor and is more efficient. The working principle of a ride-on rotary tillage machine is the same as that of a micro-tillage machine. The front axle or rear axle wheel can be equipped with tires or tillage knives. Tires are required when driving on the road, and tillage knives are used when tilling.

[0003] However, the size and weight of a riding rotary tiller are larger and heavier than a micro-tiller, so the process of replacing the wheels is naturally not as convenient as that of a micro-tiller. The best way is to use external tools to lift the entire machine so that the wheels are off the ground, making it easier to replace the wheels.

[0004] Existing models use external carrying tools to replace wheels, such as hydraulic jacks, mechanical jacks, lifting platforms and support frames. There are also ways to lift the whole machine manually or use winch tools to pull the whole machine up. These methods are troublesome or require a lot of physical strength for users, and these tools are not highly adaptable to different usage environments. Summary of the invention

[0005] 1. Technical Problems Solved

[0006] In view of the deficiencies in the prior art, the present invention proposes a vehicle-mounted bracket for facilitating wheel replacement. When the wheel needs to be replaced, only one person needs to use the power of the vehicle-mounted bracket and the mobile mechanism (riding on a micro-tillage machine) to lift himself, thereby facilitating wheel replacement.

[0007] 2. Specific technical solutions

[0013] Preferably, the locking mechanism is a quick-adjustment clamp, which includes a base, an upper rotatably connected to a rotating handle, a middle rotatably connected to a hook, and the quick-adjustment clamp also includes a hanging ear, which is fixedly arranged on the mounting seat.

[0014] Preferably, a limit assembly is provided on the support bracket, and the limit assembly is used to limit the rotation of the support bracket on the side close to the moving mechanism; the beneficial effect of this preferred embodiment is that the limit assembly can prevent the support bracket from rotating excessively, thereby improving the safety performance.

[0015] Preferably, the supporting bracket includes a supporting rod, and there are two supporting rods which are symmetrically arranged on both sides of the mounting seat, and the bottom of the supporting rod is folded toward the side away from the moving mechanism to form an extended supporting portion; the beneficial effect of this preferred embodiment is that there are two supporting rods, which makes the moving mechanism more stable when it is raised, and the extended supporting portion formed by bending further improves the stability of the support, and the supporting effect is better.

[0016] Preferably, the free ends of the two extended support parts are connected by a connecting rod, and a connecting plate is also arranged between the two extended support parts; the connecting plate is folded upward at one end close to the support rod, and after folding, the two ends of the folded part of the connecting plate are respectively connected to the two support rods; the beneficial effect of this preferred embodiment is that, through the arrangement of the connecting rod and the connecting plate, the supporting effect of the supporting bracket is better, and the strength of the supporting bracket can also be made higher.

[0018] Preferably, damping teeth are provided at the bottom of the folded part of the connecting plate, and there are multiple damping teeth which are arranged at intervals between the two support rods and contact the ground first when the support bracket is lowered; the beneficial effect of this preferred embodiment is that, through the setting of the damping teeth, the damping teeth can contact the ground first when the support bracket is placed on the ground, and its function is to reduce the initial contact angle between the support bracket and the ground, and increase the resistance between the support bracket and the ground when it is propped up.

[0019] The present invention also provides a method for facilitating wheel replacement, which uses the vehicle-mounted bracket for facilitating wheel replacement as described in the claim to replace the wheel; the method comprises the following steps:

[0020] S1, unlocking the lock mechanism to make the support bracket movable;

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-5 As shown:

[0040] A vehicle bracket for facilitating wheel replacement, such as Figure 1 , including a moving mechanism 1 and a vehicle bracket 2 located at the lower left of the moving mechanism. In this embodiment, the moving mechanism 1 is specifically a ride-on rotary tiller, and the left end of the ride-on rotary tiller can be equipped with wheel accessories such as rotary tilling tools or walking wheels according to actual needs.

[0041] When implementing, Figure 1 , Figure 2 and Figure 4 The vehicle bracket 2 mainly includes a mounting seat 200 and a supporting bracket 201; wherein the right side of the mounting seat 200 is fixed to one end of the moving mechanism 1 by bolts, the upper end of the supporting bracket 201 is rotatably connected to the left end of the mounting seat 200, and the left end of the supporting bracket 201 is the supporting end 202; Figure 1 When the supporting end 202 contacts and supports the ground, the moving mechanism 1 is lifted, making it easier to replace wheel accessories.

[0042] The principle of the main scheme is that before replacing the wheels, rotate the support bracket 201 so that the bottom of the support bracket 201 is firmly supported on the ground, start the moving mechanism (riding rotary tiller), and use the power of the moving mechanism to make it move forward, and the front end of the moving mechanism will lift the front end of the moving mechanism under the action of the support bracket; stop the power supply, and the moving mechanism is suspended in the air. At this time, different wheels can be selected for replacement according to actual conditions; the advantage of the main scheme is that the vehicle bracket 2 itself is fixed on the moving mechanism 1 (riding micro-tillage machine), which is very convenient to carry and operate; when actually supporting, only one person is required to operate, and because the power of the moving mechanism itself is used, the labor demand, operation intensity and difficulty are lower.

[0043] When implementing it, Figure 4The mounting base 200 is provided with a long sliding hole 203, and the left side of the long sliding hole 203 extends upward to form a rotating support hole 204, and the rotating support hole 204 is located on the upper side of the long sliding hole 203; and the upper end of the support bracket 201 is installed in the long sliding hole 203 through a pin shaft, and can slide toward the left and right sides along the long sliding hole 203. When the upper end of the support bracket 201 is located in the rotating support hole 204, it can only rotate, and will not move horizontally due to the limitation of the support hole; the advantage of this is that through the setting of the long sliding hole 203, the upper end of the support bracket 201 can slide along it, thereby facilitating the storage of the support bracket 201 and reducing the space occupied by the vehicle bracket 2; wherein, the setting of the rotating support hole 204 can provide a limit for the rotation of the support bracket 201, and can also prevent the support bracket 201 from slipping out during support to cause a safety accident.

[0044] In specific implementation, a locking mechanism 3 is provided on the support bracket 201, and the locking mechanism 3 can fix the support bracket 201 on the mounting seat 200 or the moving mechanism 1; specifically, the locking mechanism 3 in this scheme is a quick adjustment clamp, and the quick adjustment clamp includes a base 301, wherein the base 301 is welded on the support bracket 201, and a rotating handle 302 is rotatably connected to the base 301 through a pin, and a hook 303 is rotatably connected to the middle part of the rotating handle 302, and the quick adjustment clamp 3 also includes a hanging ear 304, and the hanging ear 304 is specifically It is fixed on the upper side of the mounting base 200 by bolts; specifically, the beneficial effect of this structure is that, through the setting of the locking mechanism 3, the support bracket 201 can be stably fixed on the moving mechanism 1 or the mounting base 200, and it is also easy to take out. The specific installation method of the support bracket 201 is to first move the left end of the support bracket 201 to the right side of the mounting base 200, and then rotate the hook 303 to cooperate with the hanging ear 304 to realize the installation and fixation of the support bracket 201. When it needs to be taken out, only the reverse operation is required.

[0045] As a preferred embodiment, Figure 5 The main body of the support bracket 201 in this embodiment is mainly composed of a support rod 205. Specifically, there are two support rods 205, which are symmetrically arranged on both sides of the mounting seat 200, wherein the upper end of the support rod 205 is rotatably connected to the long sliding hole 203 through a pin or a rotating shaft, and the bottom of the support rod 205 is folded toward the left to form an extended support portion 206. Specifically, the folding is more ****; there are two support rods 205, which provides more stable support for the mobile mechanism 1 when it is raised. The extended support portion 206 formed by bending further improves the stability of the support, so that the support effect is better;

[0046] Among them, in order to improve the supporting strength and supporting effect, the free ends of the two extended support parts 206 are connected by a connecting rod 207, and a connecting plate 208 is welded between the two extended support parts 206; the end of the connecting plate 208 close to the support rod 205 is folded upward, and after folding, the two ends of the folded part are respectively connected to the two support rods 205; through the arrangement of the connecting rod 207 and the connecting plate 208, the supporting effect of the support bracket 201 is better, and the strength of the support bracket 201 can also be made higher. Specifically, a plurality of damping teeth 210 are arranged at the bottom right of the folded part of the connecting plate 208, and the damping teeth 210 are arranged at the bottom right of the folded part of the connecting plate 208. The damping teeth 210 are arranged at intervals in the length direction of the two support rods 205, so that they can contact the ground first when the support bracket 201 is lowered. When the support bracket 201 is placed on the ground, the damping teeth 210 contact the ground first, which can reduce the initial contact angle between the support bracket 201 and the ground and increase the resistance between the support bracket 201 and the ground when it is propped up. In specific implementation, external mounting frames 209 can also be welded on both sides of the extended support part 206. Specifically, the external mounting frame 209 is used for installing external components, and the external components are specifically replacement wheels, which makes it easier to carry and use the wheels that need to be replaced.

[0047] In order to better replace the wheel, the present solution also provides a method for facilitating wheel replacement, which uses the above-mentioned on-vehicle bracket for facilitating wheel replacement to replace the wheel; the method comprises the following steps:

[0048] S1, unlock the locking mechanism 3, which is a quick adjustment fixture. First, the handle is rotated to disengage the hook 303 from the hook ear 302, so that the support bracket 201 can move;

[0049] S2, rotating the upper end of the support bracket 201, so that the upper end of the support bracket 201 can rotate at the rotation point of the mounting base 200, so that the bottom of the support bracket 201 is supported on the ground; in step S2, firstly slide the upper end of the support bracket 201 along the long sliding hole 203 to the rotating support hole 204, and then rotate the support bracket 201;

[0050] S3, start the mobile mechanism 1, and use the power of the mobile mechanism 1 to rotate one end of the mobile mechanism 1 close to the vehicle bracket 2 around the support point at the bottom of the support bracket 201, so that the mobile mechanism 1 is raised to facilitate wheel replacement;

[0051] S4, after the wheel is replaced, the mobile mechanism 1 is driven by its own power to move in the opposite direction, so that the mobile mechanism 1 descends; finally, the support bracket 201 is fixed to the mounting seat 200 by the locking mechanism 3.

[0052] Embodiment 2:

[0053] The present embodiment is different from the existing embodiment 1 in that a limit assembly 4 is provided on the support bracket 201. In the present embodiment, the limit assembly 4 is specifically a limit lever, wherein the limit lever is specifically welded to the upper side of the support bracket 201. When the support bracket 201 is rotated into place, the limit lever will be supported between the support bracket 201 and the mounting seat 200, thereby achieving the effect of rotation limit and improving safety.

[0054] Furthermore, in order to better improve the 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 cooperating with the sensing component is also provided on the moving mechanism, wherein the alarm component can specifically be a buzzer, and when the sensing component senses that the supporting bracket is rotated into place, the alarm component alarms to avoid danger caused by excessive rotation of the moving mechanism.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims.
