Description

Technical Field

[0001] The invention belongs to the technical field of field operation machinery, and in particular relates to a crawler-type field operation wheelchair. Background Art

[0002] In the context of the integration of education and agricultural practice, field work has become an important way to cultivate students' hands-on ability and understanding of agricultural production. However, for students with limited mobility, participating in field work, especially rice field work, faces many challenges. In order to gain a deeper understanding of this issue, we conducted relevant literature surveys and field investigations.

[0003] According to literature, traditional wheelchairs were originally designed to meet mobility needs indoors or on hard surfaces. Their tires are usually narrow, with a small contact area and insufficient grip. In the wet and sticky mud of rice fields, this design can easily cause the tires to sink into the mud and fail to provide sufficient traction to propel the wheelchair forward. This not only limits the range of activities for students with mobility problems, but can also cause them to encounter safety hazards when working in the fields, seriously affecting their work experience and participation.

[0004] The actual investigation also verified this point. We found that in the rice fields, the tires of traditional wheelchairs often get stuck in the mud and cannot move forward, and multiple people are needed to help pull the wheelchair out. This not only increases the complexity and difficulty of the work, but may also cause students with mobility problems to feel frustrated and inferior during the work.

[0005] In summary, farm work requires a mechanical aid for students with mobility problems to carry out farm-related work. Summary of the invention

[0006] The purpose of the present invention is to provide a tracked wheelchair for field operations in order to solve the above-mentioned problem that students with mobility problems need a mechanical aid to assist them in carrying out farm operations.

[0007] The technical solution adopted by the present invention is as follows: A crawler-type field work wheelchair comprises a work support plate, a power body is welded to the lower surface of the work support plate, the inner surface of the front end of the power body is movably connected with a reference force-bearing piece, a lower connecting rod is welded to the lower surface of the reference force-bearing piece, a bidirectional motor is fixedly connected to the outer surface of one end of the lower connecting rod away from the reference force-bearing piece, a front end cross bar is welded to the outer surface of one end of the bidirectional motor away from the lower connecting rod, a telescopic motor body is fixedly connected to the outer surface of the front end cross bar, a rolling gear is fixedly connected to the outer surface of the output end of the bidirectional motor, a rolling gear is movably sleeved on the outer surface of the output end of the telescopic motor body, a cylinder is fixedly connected to the outer surface of the front end of the reference force-bearing piece, an upper transverse sleeve rod is welded to the outer surface of the cylinder output end, rolling gears are movably sleeved on the inner surfaces of both sides of the upper transverse sleeve rod, and an auxiliary crawler track is movably connected to the outer surface of the rolling gear.

[0008] By adopting the above technical scheme, under normal traveling state, the auxiliary track provides more contact area for the equipment to avoid being trapped in mud. The bidirectional motor is turned on or off according to the actual situation. By turning on the bidirectional motor, the auxiliary track is driven to rotate, and the clamping mechanism provides power for the equipment. The forward extension of the upper horizontal sleeve facilitates contact with a slope of a certain height at the front end, and also increases the force-bearing area for climbing and crossing. The rotation of the reference force-bearing member, when a small angle turn is required, the operation is carried out through the overall steering of the auxiliary track, avoiding the energy loss caused by the back and forth pause of the power body and the reverse work, and increasing durability. When the person in the wheelchair gets on the seat, the lower end of the wheelchair is retracted inward by the cylinder, and the auxiliary track is in a state of getting higher and higher from the front end to the rear end. The bidirectional motor is turned on at the bottom, and the overall auxiliary track rotates, holding the wheelchair and driving the person up until the seat position is fixed. The rolling gear is extended and retracted through both sides to complete the adjustment of the support displacement and ensure the stability of the lifting.

[0010] By adopting the above technical solution, the support plate provides better support for the cylinder, while providing lower support and leg placement area for personnel. The high-torque motor provides mechanical power for the rotation of the reference force-bearing member. The connecting plate connects the front cross bar and both ends of the cylinder to facilitate the connection between the upper and lower ends, thereby providing a guarantee for the stability of the support.

[0012] By adopting the above technical solution, a reeling mechanism is arranged inside the dual-output reel and the reel, so that the straps can be reeled back conveniently. The difference is that the dual-output reel has double-layer synchronous reeling, so that the wheelchair can be fixed conveniently, while the reel is disassembled and fixed by buckles, so as to fix the personnel.

[0013] In a preferred embodiment, a seat is provided on the inner surface of the work support plate, and a secondary support plate is welded on the outer surface of the seat.

[0016] By adopting the above technical solution, the adjusting sleeve can be extended and retracted to adjust the camera height. The mobile phone holder is convenient for fixing the mobile phone for equipment operation, and is also convenient for taking pictures, watching teaching videos, etc. The camera can achieve better shooting effects and adjust the height of the adjusting sleeve, which is convenient for shooting farther away from the farmland and is conducive to research and study.

[0017] In a preferred embodiment, a six-axis robotic arm is disposed on the upper surface of the auxiliary support plate, and a clamping mechanism is disposed on the outer surface of the output end of the six-axis robotic arm.

[0018] By adopting the above technical solution, the six-axis robot arm can rotate at various angles through different motors to achieve output ends at different positions, which is convenient for front-end operations and allows users to complete operations without getting off the vehicle. A threaded rod is set at the output end of the six-axis robot arm, and the clamping mechanism is fixed by rotation. It has a built-in telescopic motor, which is convenient for clamping objects and pulling out crops for close observation. Similarly, weeding operations can be performed, and drill bits can be replaced by rotation, which facilitates operations such as drilling holes in farmland and sowing.

[0019] In a preferred embodiment, an extension plate is welded to the outer surface of the front end of the auxiliary support plate, and a placement box is fixedly connected to the upper surface of the extension plate.

[0020] By adopting the above technical solution, the extension plate is convenient for placing items, and the front end corresponds to the top of the power track, which is convenient for filtering the silt brought up and avoiding more and more tests on the motor torque.

[0021] In a preferred embodiment, a fixing plate is welded to the upper surface of the extension plate, a working plate is movably connected to the upper surface of the fixing plate in a damping manner, and an auxiliary supporting plate is movably connected to the outer surface of one end of the working plate away from the fixing plate.

At the same time, under some suitable conditions, users can perform agricultural operations on the work board to avoid the inconvenience caused by going to the field. When the weight is large, the auxiliary support plate is folded and fixed at the other end to facilitate further support.

[0023] In a preferred embodiment, a traction block is welded on the outer surface of the rear end of the power body, and power bodies are welded on the outer surfaces of both sides of the power body.

[0024] By adopting the above technical solution, when the equipment is completely stuck or cannot operate due to power failure, the traction block can be used to facilitate external mechanical traction to a safe position, and the power body can drive the driving wheel to rotate through motors set at both ends.

[0025] In a preferred embodiment, driving wheels are provided on the outer surfaces of both ends of the power body, auxiliary wheels are provided on the outer surface of the power body, and the driving wheels are movably connected to the outer surfaces of the auxiliary wheels with power tracks.

[0026] By adopting the above technical solution, the rotation of the driving wheel drives the power track, and the auxiliary wheel assists in ensuring that the power track moves stably on the ground.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. The seat is fixed to the work support plate with screws. When the user is a person with mobility impairment and has his own wheelchair, the seat is removed and the cylinder is retracted inward. The auxiliary track is in a state where the front end is higher and higher towards the rear end. The double-output reel and the reel are both equipped with a reeling mechanism to facilitate the reeling of the straps. The difference is that the double-output reel has a double-layer synchronous reeling to facilitate the fixing of the wheelchair. The reel is disassembled and fixed by buckles to fix the person. The two straps of the double-output reel are used to tie the wheelchair. The buckles are connected to the person and the wheelchair. After the fixation is completed, the double-output reel and the reel are reeled to support and pull from the top. The bidirectional motor is turned on from the bottom, and the overall auxiliary track rotates to hold the wheelchair and drive the person up until the seat is fixed.

[0029] 2. The rolling gear is extended and retracted on both sides to adjust the support displacement and ensure the stability of the lifting. Under normal travel conditions, the auxiliary track provides more contact area for the equipment to avoid silt sinking. The bidirectional motor is turned on or off according to the actual situation. By turning on the bidirectional motor, the auxiliary track is driven to rotate, and the clamping mechanism provides power for the equipment. The extension of the upper horizontal sleeve rod facilitates contact with a slope with a certain height at the front end, and also increases the force-bearing area for climbing and crossing. The rotation of the reference force-bearing parts, when a small angle turn is required, the operation is carried out through the overall steering of the auxiliary track, which avoids the energy loss caused by the back and forth pause of the power body and the reverse work, and increases durability;

[0030] 3. The equipment is set up with a work plate that can be rotated to a horizontal section, so that users can place relevant items for research, such as weeds and crops that need to be identified. At the same time, under some suitable conditions, users can perform agricultural operations on the work plate to avoid the inconvenience caused by going to the ground. When the weight is large, the auxiliary support plate is folded and fixed at the other end for further support. Similarly, the six-axis robotic arm and clamping mechanism are set up to facilitate users to conduct agricultural research;

[0031] 4. This wheelchair provides disabled people with the ability to move freely in rice fields, allowing them to complete farm work and other daily activities more independently, thereby improving their quality of life. By participating in farming and achieving results, disabled people can feel their own value and sense of achievement, thereby improving their self-confidence and happiness.

When the person in the wheelchair gets on the seat, the lower end of the wheelchair is retracted inwardly by the cylinder 10, and the auxiliary crawler 12 is in a state of getting higher and higher from the front end to the rear end. The two-way motor 6 is turned on at the bottom, and the overall auxiliary crawler 12 rotates, holding the wheelchair and driving the person up until the position of the seat 18 is fixed.

A threaded rod is set at the output end of the six-axis robot arm 23, and the clamping mechanism 24 is fixed by rotation. A built-in telescopic motor is convenient for clamping objects and pulling out crops for close observation. Similarly, weeding operations can be performed, and drill bits can be replaced by rotation, which facilitates operations such as drilling holes in farmland and sowing.

[0059] Reference Figure 1-3 A traction block 30 is welded on the outer surface of the rear end of the power body 2, and power bodies 31 are welded on the outer surfaces of both sides of the power body 2.

[0060] When the equipment is completely stuck or cannot operate due to power failure, the traction block 30 is used to facilitate external mechanical traction to a safe position, and the power body 31 is driven by the motors arranged at both ends to drive the driving wheel 32 to rotate.

[0061] Driving wheels 32 are arranged on the outer surfaces of both ends of the power body 31 , and auxiliary wheels 33 are arranged on the outer surface of the power body 31 . The driving wheels 32 are movably connected to the outer surfaces of the auxiliary wheels 33 .

[0062] The rotation of the driving wheel 32 drives the power track 34 , and the auxiliary wheel 33 assists in ensuring that the power track 34 moves stably on the ground.

[0063] The implementation principle of a crawler-type field work wheelchair embodiment of the present invention is:

[0064] The device is provided with a motor inside the power body 31, which drives the power crawler 34 to move by rotating the driving wheel 32. When turning, one side rotates forward and the other side rotates reversely to complete a U-turn or turning. The seat 18 is fixed to the corresponding work support plate 1 with screws. When the user is a person with mobility retardation and brings his own wheelchair, the seat 18 is removed, the cylinder 10 is retracted inward, and the auxiliary crawler 12 is in a state where the front end is higher and higher toward the rear end.

The two straps of the double-output reel 15 are used to tie the wheelchair, and the buckle 17 is connected to the person and the wheelchair. After the fixation is completed, the double-output reel 15 and the reel 16 are reeled in. The auxiliary crawler 12 is rotated to support and traction, and the bidirectional motor 6 is turned on at the bottom. The auxiliary crawler 12 rotates as a whole, holding the wheelchair and driving the person up until the position of the seat 18 is fixed. The rolling gear 9 is extended and retracted on both sides to complete the adjustment of the support displacement and ensure the stability of the lifting. In the normal traveling state, the auxiliary crawler 12 provides more contact area for the equipment to avoid silt sinking. The bidirectional motor 6 is turned on or off according to the actual situation. By turning on the bidirectional motor 6, the auxiliary crawler 12 is driven to rotate, and the clamping mechanism 24 provides power for the equipment. The forward extension of the upper horizontal sleeve rod 11 facilitates contact with a slope with a certain height at the front end, and also increases the force-bearing area for climbing and crossing. The rotation of the reference force-bearing member 4, when a small angle turn is required, the operation is carried out through the overall steering of the auxiliary crawler 12, which avoids the energy loss caused by the back and forth pauses and reverse work of the power body 31, and increases durability.
