Description

Technical Field

[0001] The utility model relates to the technical field of crawler wheels, and particularly relates to a high-ground-clearance replaceable triangular crawler wheel suitable for tobacco operations in hilly and mountainous areas. Background Art

[0002] The triangular structure of the triangular crawler wheel enables it to have unique adaptability on different terrains. On soft ground (such as sandy land and muddy land), due to the large contact area between the crawler and the ground, it can effectively disperse the weight of the equipment and reduce the possibility of subsidence. At the same time, on rough terrains, the triangular crawler wheel can better fit the ground contour through the flexibility of the crawler, cross obstacles, and maintain the stable operation of the equipment.

[0003] The triangular crawler wheel has good passability. Compared with traditional wheels, the triangular crawler wheel has stronger off-road capabilities. It can easily cross obstacles such as ditches and stones, and can travel in various complex terrains (such as mountainous areas, wetlands, snowfields, etc.), and can provide better mobility for mechanical equipment in fields such as agriculture, forestry, military, and engineering construction.

[0004] In harsh working environments, such as rough terrains or roads containing a large amount of sand and gravel, when driving on uneven ground, the chassis is severely scratched. Moreover, in tobacco operations in hilly and mountainous areas, conventional triangular crawler wheels are very easy to be damaged and inconvenient to replace.

[0005] If the triangular crawler wheel is not adjusted according to the specified tension during installation, being too loose or too tight will affect its stability during use. When the crawler tension is too loose during installation, there may be no obvious problems in the initial stage of equipment operation. However, with use, due to factors such as its own gravity and impact force during operation, the crawler will gradually become looser. Content of the Utility Model

[0051] In one embodiment, a high-ground-clearance replaceable triangular crawler wheel applicable to tobacco operations in hilly and mountainous areas includes: a driving wheel 101 for connecting to the power output end of a vehicle; a support frame 102 including a bottom plate 103, side plates 104, and a plurality of rib plates 105. The bottom plate 103 is fixedly connected to the side plates 104, and the rib plates 105 are fixedly arranged between the bottom plate 103 and the side plates 104. The rib plates 105 are used to enhance the strength of the connection between the side plates 104 and the bottom plate 103. The driving wheel 101 is rotatably connected to the top of the side plates 104; a vehicle frame 106 is fixedly connected to the bottom plate 103, and a plurality of first axle shafts 107 are arranged on the vehicle frame 106. A supporting wheel 108 is arranged at each end of each first axle shaft 107; a first bracket 109 is fixedly connected to one end of the vehicle frame 106. A second axle shaft 110 is arranged at the end of the first bracket 109 away from the vehicle frame 106, and a guiding wheel 111 is arranged at each end of the second axle shaft 110; two sleeves 112 are fixedly connected to the other end of the vehicle frame 106, and are fixedly connected by a connecting plate 113 between the two sleeves 112; a second bracket 114 includes two branch pipes 115, a connecting block 116, and a hydraulic rod 117. The branch pipes 115 are telescopically installed in the sleeves 112, and are fixedly connected by the connecting block 116 between the two branch pipes 115. The connecting plate 113 is connected to the connecting block 116 by the hydraulic rod 117. The hydraulic rod 117 is used to drive the branch pipes 115 to telescopically move in the sleeves 112. A third axle shaft 118 is arranged at the end of the second bracket 114 away from the vehicle frame 106, and a guiding wheel 111 is arranged at each end of the third axle shaft 118; a crawler 119 is wrapped around the driving wheel 101, the guiding wheels 111, and the supporting wheels 108.

[0052] Further, a support strengthening plate 131 is arranged between the first bracket 109 and the vehicle frame 106, and a support strengthening plate 131 is arranged between the second bracket 114 and the vehicle frame 106 to enhance the structural strength of the connection.

[0053] The number of the first axle shafts 107 can be 3, and correspondingly 6 supporting wheels 108 are arranged. The design of multiple supporting wheels 108 can evenly distribute the pressure and improve the reliability of equipment use. Of course, it can also be 5 first axle shafts 107, 5 first axle shafts 107, or other quantity designs.

[0054] Among them, the support frame 102 can be provided with 4 rib plates 105 at equal intervals. Of course, it can also be 3 rib plates 105, 5 rib plates 105, or other quantity designs.

[0055] The technical effects of the high-ground-clearance replaceable triangular crawler wheel applicable to tobacco operations in hilly and mountainous areas are as follows:

[0056] First, the adaptability to tobacco operations in hilly and mountainous areas

[0057] The high ground clearance design offers good passability: In hilly and mountainous areas, the terrain undulates greatly and there may be many obstacles such as stones and potholes. The high ground clearance design of this product allows for a large gap between the chassis and the ground during vehicle operation, enabling it to easily cross these obstacles, reducing the risk of the chassis being knocked and damaged, and ensuring the normal passage of the tobacco operation vehicle in complex terrains. For example, in hilly areas where tobacco is planted, the high ground clearance enables the vehicle to smoothly pass over ridges or bypass protruding rocks, avoiding being trapped due to too low a chassis, thus improving the operation efficiency.

[0058] The triangular crawler wheels have strong grip: The structure of the triangular crawler wheels results in a large contact area with the ground. On soft soil or sloping ground in hilly and mountainous areas, the large contact area can provide stronger grip, preventing the vehicle from slipping, which is very important for tobacco operation vehicles because they may need to drive or operate on inclined slopes during mountain operations. Good grip helps ensure the stability and safety of the vehicle. For example, during tobacco transplanting or harvesting operations, when the vehicle is driving on a slippery slope, the triangular crawler wheels can stably support the vehicle and move forward smoothly, avoiding operation interruption or danger caused by slipping.

[0059] Since the triangular crawler wheels distribute the vehicle's weight over a larger area, compared with traditional wheels, they exert less pressure on the soil. In tobacco planting areas, this can reduce the damage to the soil structure, protect the soil fertility and water retention capacity, and is beneficial to the growth of tobacco. Especially in some cases where multiple field operations are required, such as fertilization and irrigation, the lesser degree of soil damage can maintain the good state of the soil and improve the yield and quality of tobacco.

[0060] II. Advantages brought by the structural design

[0061] The support frame 102 is structurally connected with high strength: The fixed connection method of the bottom plate 103, side plates 104 and multiple rib plates 105 in the support frame 102 effectively improves the strength of the connection between the side plates 104 and the bottom plate 103. During vehicle operation, especially on bumpy roads in hilly and mountainous areas, this high-strength connection can ensure the stable installation and normal operation of the drive wheel 101. When the vehicle is subjected to forces from different directions, such as the impact force when crossing a gully or the lateral force when turning, the high-strength support frame 102 structure can prevent the drive wheel 101 from shifting or shaking, ensuring the stability of power output.

[0062] The adjustable second bracket 114 can adapt to different tensions of the crawler 119: With the telescopic design of the second bracket 114, the hydraulic rod 117 drives the telescopic movement of the branch pipe 115 within the sleeve 112, facilitating the adjustment of the position of the idler wheel 111, thereby achieving the adjustment of the tension of the crawler 119. In different operating environments in hilly and mountainous areas, the crawler 119 may become loose or too tight due to terrain undulations or wear during operation. For example, during long-term tobacco operations, the crawler 119 may become loose due to continuous stretching. At this time, the second bracket 114 can be adjusted through the hydraulic rod 117 to move the idler wheel 111, thereby tightening the crawler 119, ensuring the normal operation of the crawler wheels, and reducing the occurrence of faults such as derailment of the crawler 119.

[0063] Facilitates maintenance and replacement: The adjustable structure also provides convenience when components of the crawler wheels need to be repaired or replaced. For example, when a certain idler wheel 111 is damaged, the second bracket 114 can be adjusted to expose the damaged idler wheel 111 in a convenient position for operation, facilitating the disassembly and replacement by maintenance personnel, and reducing maintenance time and costs.

[0064] III. Improvement of Vehicle Stability and Load Capacity by the Overall Structure

[0065] The layout of the track rollers 108 and idler wheels 111 can evenly distribute the weight: Multiple track rollers 108 provided on the frame 106 and the idler wheels 111 at both ends can evenly distribute the weight of the vehicle on the crawler 119. When operating in hilly and mountainous areas, the vehicle may need to carry equipment related to tobacco planting, harvesting, or transportation, and a heavy load requires a good load-bearing structure. This layout can ensure that the crawler wheels can still operate stably under the vehicle load, without causing damage to components such as the crawler 119 and axle due to excessive local stress, improving the overall load capacity of the vehicle.

[0066] The reasonable setting of the idler wheel 111 and track roller 108 helps to guide the running direction of the crawler 119 and maintain the stability of the vehicle during driving. On the rugged roads in hilly and mountainous areas, the vehicle is prone to deviation. A stable driving trajectory can ensure the accuracy of tobacco operations. For example, in operations such as precise fertilization and tobacco picking, the vehicle can accurately reach the predetermined position.

[0067] The height range from the axis of the driving wheel 101 to the bottom plate 103 of the support frame 102 is 450 to 500 millimeters. The height from the axis of the driving wheel 101 to the bottom plate 103 of the support frame 102 can be 450 millimeters, 500 millimeters or other values before. In a conventional triangular crawler wheel, this height, that is, the ground clearance height, usually does not exceed 350 millimeters. Therefore, the high ground clearance design of the embodiment of the present utility model enables the vehicle to have a large gap between the chassis and the ground during driving, can easily cross these obstacles, reduces the risk of the chassis being knocked and damaged, and ensures the normal passage of the tobacco operation vehicle in complex terrains.

[0068] Refer to Figure 4 and Figure 5 , Figure 4 is the structural diagram of the drive shaft 120 of the high ground clearance replaceable triangular crawler wheel applicable to tobacco operations in hilly and mountainous areas according to the embodiment of the present utility model; Figure 5 is the structural diagram of the drive shaft 120 of the high ground clearance replaceable triangular crawler wheel applicable to tobacco operations in hilly and mountainous areas according to the embodiment of the present utility model.

[0069] In one embodiment, the high ground clearance replaceable triangular crawler wheel applicable to tobacco operations in hilly and mountainous areas includes: a driving wheel 101 for connecting to the power output end of the vehicle; a support frame 102 including a bottom plate 103, side plates 104 and a plurality of rib plates 105. The bottom plate 103 is fixedly connected to the side plates 104, and the rib plates 105 are fixedly arranged between the bottom plate 103 and the side plates 104. The rib plates 105 are used to enhance the strength of the connection between the side plates 104 and the bottom plate 103, and the driving wheel 101 is rotatably connected to the top of the side plates 104; a vehicle frame 106 fixedly connected to the bottom plate 103, and a plurality of first axle shafts 107 are arranged on the vehicle frame 106, and a supporting wheel 108 is arranged at each end of each first axle shaft 107; a first bracket 109 fixedly connected to one end of the vehicle frame 106, a second axle shaft 110 is arranged at the end of the first bracket 109 away from the vehicle frame 106, and a guiding wheel 111 is arranged at each end of the second axle shaft 110; two sleeves 112 fixedly connected to the other end of the vehicle frame 106, and the two sleeves 112 are fixedly connected by a connecting plate 113; a second bracket 114 including two branch pipes 115, a connecting block 116 and a hydraulic rod 117. The branch pipes 115 are telescopically installed in the sleeves 112, the two branch pipes 115 are fixedly connected by the connecting block 116, the connecting plate 113 is connected to the connecting block 116 by the hydraulic rod 117, and the hydraulic rod 117 is used to drive the branch pipes 115 to telescopically move in the sleeves 112. A third axle shaft 118 is arranged at the end of the second bracket 114 away from the vehicle frame 106, and a guiding wheel 111 is arranged at each end of the third axle shaft 118; a crawler 119 is externally wrapped around the driving wheel 101, the guiding wheels 111 and the supporting wheels 108.

[0070] The driving shaft 120 includes: a top cover 121; a flange cover 122 that abuts against the top cover 121 and is disposed inside the top cover 121. The top cover 121 is fixedly connected to the flange cover 122 by screws. An opening is provided at the center of the flange cover 122, and the flange cover 122 is fixedly connected to the top of the side plate 104; a bearing 123 is disposed in the central opening of the flange cover 122, and the bearing 123 abuts against the inside of the top cover 121; a main shaft 124 is disposed in the central opening of the flange cover 122. One end of the main shaft 124 abuts against the inside of the top cover 121. The bearing 123 is sleeved on the main shaft 124. The main shaft 124 is provided with a protrusion 125, and the main shaft 124 is used to drive the driving wheel 101 to rotate.

[0071] In terms of structural stability, the driving shaft 120 has a multi-layer fixed structure. The top cover 121 and the flange cover 122 are fixedly connected by screws. This connection method can provide a relatively stable connection structure. During the operation of the vehicle, especially when facing complex road conditions such as bumps and vibrations during tobacco operations in hilly and mountainous areas, the multi-layer fixed structure can prevent relative displacement between the various components of the driving shaft 120. Effect: For example, when the vehicle crosses a pothole or travels on an uneven hillside, the tight connection between the top cover 121 and the flange cover 122 ensures the integrity of the structure of the driving shaft 120, enabling the driving shaft 120 to stably transmit power and avoiding problems such as power transmission interruption or abnormal wear caused by component loosening.

[0072] Positioning and support of the bearing 123: The bearing 123 is disposed in the central opening of the flange cover 122 and abuts against the inside of the top cover 121. This layout enables the bearing 123 to be accurately positioned in the structure of the driving shaft 120 and also provides stable support for the bearing 123. The bearing 123 plays a key role during the rotation of the driving shaft 120. It bears the radial force of the main shaft 124 and allows the main shaft 124 to rotate smoothly therein.

[0073] In terms of power transmission and reliability in the cooperation between the main shaft 124 and other components: The main shaft 124 is disposed in the central opening of the flange cover 122, one end abuts against the inside of the top cover 121, and a bearing 123 is sleeved on the main shaft 124. This structural design enables the main shaft 124 to maintain good coaxiality during rotation. Coaxiality is crucial for power transmission because it ensures that power can be efficiently transmitted from the main shaft 124 to the driving wheel 101. During the operation of the tobacco operation vehicle, whether it is between the flat tobacco planting ridges or on the slopes of hilly and mountainous areas, the good cooperation between the main shaft 124 and other components can ensure the reliability of power transmission. For example, when the vehicle is towing tobacco planting equipment or transporting harvested tobacco, stable power transmission can avoid problems such as low operation efficiency caused by power loss.

[0074] The main shaft 124 is provided with a protrusion 125, which helps the connection between the main shaft 124 and the driving wheel 101. This design can enhance the connection strength between the main shaft 124 and the driving wheel 101, enabling the main shaft 124 to drive the driving wheel 101 to rotate more effectively. Under the complex terrain conditions in hilly and mountainous areas, the tobacco operation vehicle needs to overcome greater resistance, such as when climbing slopes or driving on muddy ground. The protrusion 125 on the main shaft 124 can ensure that there is no slipping between the main shaft 124 and the driving wheel 101 under high load conditions, thus ensuring that the vehicle has sufficient power to complete the tobacco operation tasks.

[0075] Furthermore, it also includes: a axle connection member 126, with a through hole provided at the central position, one end of the main shaft 124 extends into the through hole, and one end of the axle connection member 126 is arranged close to the driving wheel 101.

[0076] Furthermore, the driving wheel 101 includes: a central sleeve, an intermediate plate 127, a first flange 128, a second flange 129, and a plurality of wheel side shafts 130. The central sleeve is arranged in the central area of the intermediate plate 127, and a groove corresponding to the protrusion 125 on the main shaft 124 is provided on the inner circle of the central sleeve; the first flange 128 and the second flange 129 are of the same size and shape, the intermediate plate 127 is arranged between the first flange 128 and the second flange 129, and the wheel side shafts 130 pass through the intermediate plate 127, the first flange 128, and the second flange 129, and the wheel side shafts 130 are arranged on the outer circles of the intermediate plate 127, the first flange 128, and the second flange 129.

[0077] In terms of the connection reliability between the driving wheel 101 and the main shaft 124, the cooperation between the central sleeve and the main shaft 124 is tight and reliable:

[0078] A groove corresponding to the protrusion 125 on the main shaft 124 is provided on the inner circle of the central sleeve. This design achieves the effect of a key connection. During the power transmission process, the protrusion 125 of the main shaft 124 is embedded in the groove of the central sleeve, which can effectively transmit torque and prevent relative sliding between the driving wheel 101 and the main shaft 124 during high torque transmission.

[0079] In terms of structural strength and stability, a multi-layer board structure design is adopted: the drive wheel 101 has a structure where the middle board 127 is sandwiched between the first flange 128 and the second flange 129. This multi-layer board structure increases the overall thickness and structural strength of the drive wheel 101. The first flange 128 and the second flange 129 can be regarded as the outer protection and strengthening structures of the drive wheel 101, while the middle board 127 plays a role in internal support and stress dispersion. When the drive wheel 101 operates in complex hilly and mountainous terrains, such as when crossing stones or potholes, the multi-layer board structure can withstand greater impact forces and is not easily deformed or damaged. This structure helps to extend the service life of the drive wheel 101 and reduce the possibility of tobacco operation interruption caused by drive wheel 101 failures.

[0080] The wheel side shaft 130 passes through the outer rings of the middle board 127, the first flange 128, and the second flange 129. This layout strengthens the outer ring of the drive wheel 101. The wheel side shaft 130 is like a skeleton, connecting the multi-layer boards together and increasing the structural rigidity of the outer ring of the drive wheel 101. During the process of the drive wheel 101 contacting the crawler 119 and transmitting power, the wheel side shaft 130 can effectively prevent the outer ring of the drive wheel 101 from deforming or twisting. Especially when the vehicle turns or travels on uneven ground, the wheel side shaft 130 helps to maintain the shape stability of the drive wheel 101, thus ensuring the normal operation of the crawler 119 and maintaining the driving stability of the vehicle.

[0081] In one embodiment, a work vehicle applicable to tobacco operations in hilly and mountainous areas includes the high-ground-clearance replaceable triangular crawler wheel applicable to tobacco operations in hilly and mountainous areas as described above. In tobacco operations in hilly and mountainous areas, the terrain is complex and changeable, with a large number of steep slopes, gullies, and rough roads. The high-ground-clearance design of the high-ground-clearance replaceable triangular crawler wheel keeps a large distance between the work vehicle chassis and the ground. The work vehicle can easily cross obstacles such as ridges, small stones, and shallow potholes, effectively avoiding damage to the chassis by scraping. The structure of the support frame 102 of the crawler wheel (including the bottom plate 103, side plates 104, rib plates 105, etc.), the adjustable second bracket 114, and the reasonable layout of the idler wheels 108 and guide wheels 111 on the vehicle frame 106 together enhance the overall structural stability of the work vehicle. During the tobacco operation process, the vehicle may need to carry equipment or goods of different weights. This stable structure can ensure the smooth operation of the work vehicle under load conditions and prevent dangerous situations such as tilting or rolling over caused by unstable structure.

[0082] The design of the replaceable triangular track wheel facilitates the maintenance of the work vehicle. When the triangular track wheel is worn, damaged, or needs to operate on different terrains (such as from hilly mountainous areas to relatively flat tobacco processing sites), the track wheel can be conveniently replaced. For example, if a certain component of the track wheel (such as the guide wheel 111 or the idler wheel 108) is damaged, there is no need for complex operations to disassemble the entire vehicle chassis. The track wheel can be directly replaced, which greatly shortens the maintenance time and improves the usage efficiency of the work vehicle.

[0083] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
