Description

Technical Field

[0001] This utility model belongs to the field of guide wheel assembly technology, specifically a guide wheel assembly for agricultural machinery path calibration. Background Technology

[0002] In agricultural machinery, transplanters, seedling diggers, and fertilizer applicators all require continuous, equidistant placement of seedlings, seedling digging, and fertilizer application along the center of the ridge. However, the ridges in the field are not straight. Therefore, during operation, the operator needs to continuously control the front wheels of the machine for guidance. Guide wheel sets are needed to ensure that the transplanter always moves along the center of the ridge. Existing guide wheel sets are not convenient for adjusting the roller spacing. Adjustment often requires disassembling and assembling multiple sets of bolts, which is time-consuming. Furthermore, when used in the field, they are easily contaminated with water, and the resulting corrosion makes the bolts even more difficult to disassemble and assemble, reducing the adjustment speed. To address this, we propose an agricultural machinery path calibration guide wheel set. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a guide wheel set for agricultural machinery path calibration, which effectively solves the problems of existing guide wheel sets being inconvenient to adjust the roller spacing, often requiring the disassembly and assembly of multiple bolts, which is time-consuming, and being prone to water contamination during field use, resulting in rust that makes the bolts even more difficult to disassemble and assemble, thus reducing the adjustment speed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a guide wheel assembly for agricultural machinery path calibration, comprising a crossbeam, sleeves on both the left and right sides of the inner wall of the crossbeam, support frames on both the left and right sides of the inner cavity of the crossbeam, adjusting screws on the inner walls of the support frames, adjusting blocks on the outer walls of the adjusting screws on both the left and right sides, the opposite ends of the two sets of sleeves respectively located on the opposite side walls of the two sets of adjusting blocks, a rotating rod on the bottom wall of the crossbeam, the top end of the rotating rod penetrating the inner wall of the crossbeam and having a first bevel gear, a second bevel gear on the opposite ends of the two sets of adjusting screws, the second bevel gear meshing with the first bevel gear, and wheel assembly structures on the opposite ends of the two sets of sleeves.

[0005] Preferably, the wheel assembly structure includes a supporting circular tube, the inner wall of which is provided with a rotating shaft, the bottom end of which is provided with a supporting plate, and the side wall of the supporting plate is provided with a roller.

[0006] Preferably, the upper side of the inner wall of the supporting circular tube is provided with a flange extending horizontally toward the axis of the supporting circular tube, the inner wall of the rotating shaft is provided with a limiting rod, the outer wall of the limiting rod is provided with a limiting ring, the limiting ring abuts against the bottom wall of the flange, and the upper end of the limiting rod is provided with a cap, the cap abutting against the top wall of the flange.

[0007] Preferably, the left and right sides of the inner wall of the crossbeam are hexagonal, and the outer walls of the sleeves on the left and right sides match the left and right sides of the inner wall of the crossbeam.

[0008] Preferably, a mounting bracket is provided on the rear side wall of the crossbeam, and sealing rings are provided on both the left and right sides of the inner wall of the crossbeam, with the sleeve located on the inner wall of the sealing rings.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This agricultural machinery path calibration guide wheel set, through the combination of devices such as crossbeams, sleeves and support frames, allows the device to easily adjust the spacing between the left and right wheel sets. After symmetrical adjustment, the symmetry line of the wheel sets on both sides is completely aligned with the center line of the ridge. When the agricultural machinery is in motion, the wheel set structure can always fit against the sides of the ridge top or the edge of the furrow, forming a symmetrical support and guiding benchmark. This agricultural machinery path calibration guide wheel assembly, through the combination of supporting round tubes, rotating shafts and supporting plates, can facilitate path calibration and guidance along the direction of the ridges, automatically calibrate the steering efficiency of the guide wheels, and facilitate agricultural machinery to operate on the ridges; This agricultural machinery path calibration guide wheel assembly, through the combination of limiting rods, rotating shafts, and caps, allows the device to easily control the maximum deflection angle of the rollers within a safe range through bidirectional restriction, preventing the rollers from completely detaching from the ridge, avoiding missed tillage and seedling damage caused by the agricultural machinery "going off track," ensuring that the guide assembly always maintains a "ridge top centered" working state, and protecting the guide mechanism from damage in extreme terrain.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0013] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a guide wheel assembly for agricultural machinery path calibration. Sleeves 101 are slidably connected to both sides of the inner wall of a crossbeam 100, providing support for the wheel assembly structure 2. Support frames 102 are fixedly connected to both sides of the inner cavity of the crossbeam 100, supporting adjusting screws 103. Adjusting screws 103 are rotatably connected to the inner walls of the support frames 102, facilitating the movement of adjusting blocks 104. Adjusting blocks 104 are screwed onto the outer walls of the adjusting screws 103 on both sides, facilitating the movement of the sleeves 101. The opposite ends of the two sets of sleeves 101 are respectively fixedly connected... On the opposite sidewalls of the two sets of adjusting blocks 104, the bottom wall of the crossbeam 100 is rotatably connected to a rotating rod 105. The rotating rod 105 facilitates the rotation of the first bevel gear 106. The top of the rotating rod 105 passes through the inner wall of the crossbeam 100 and is fixedly connected to the first bevel gear 106. The first bevel gear 106 facilitates the rotation of the second bevel gear 107. The opposite ends of the two sets of adjusting screws 103 are fixedly connected to the second bevel gear 107. The second bevel gear 107 facilitates the rotation of the adjusting screws 103. The second bevel gear 107 meshes with the first bevel gear 106. The opposite ends of the two sets of sleeves 101 are fixedly connected to a wheel assembly structure 2.

[0014] In this embodiment: the crossbeam 100 is installed on the agricultural machinery. The rotating rod 105 drives the first bevel gear 106 to rotate, which in turn drives the second bevel gear 107 to rotate. The second bevel gear 107 drives the adjusting screw 103 to rotate. The left and right adjusting screws 103 rotate in opposite directions. The adjusting screw 103 drives the adjusting block 104 to move, so that the left and right adjusting blocks 104 move towards or away from each other. The adjusting block 104 drives the sleeve 101 to move, which in turn drives the wheel assembly structure 2 to move and adjust in the center. This allows the device to easily adjust the distance between the left and right wheel assembly structures 2. After symmetrical adjustment, the symmetry line of the wheel assembly structures 2 on both sides is completely aligned with the center line of the ridge. When the agricultural machinery is running, the wheel assembly structure 2 can always fit against the sides of the ridge top or the edge of the furrow, forming a symmetrical support and guiding benchmark.

[0015] The wheel assembly structure 2 includes a support tube 201, which is fixedly connected to the sleeve 101. A rotating shaft 202 is sleeved on the inner wall of the support tube 201, which facilitates the support plate 203. The bottom end of the rotating shaft 202 is fixedly connected to the support plate 203, which facilitates the support of the roller 204. The side walls of the support plate 203 are rotatably connected to the roller 204.

[0016] In this embodiment: When the agricultural machinery is moving forward, if the ridge does not bend to the side, the rollers 204 at both ends are in a relatively horizontal state, and the two rollers 204 are in a balanced state, allowing the agricultural machinery to move straight forward. When the ridge bends to the left in the direction of the agricultural machinery's movement, the left roller 204 will gradually climb to the edge of the ridge, increasing the forward resistance of the left roller 204. At the same time, the right roller 204 will also gradually be lifted, reducing the forward resistance of the right roller 204. This causes the two rollers 204 to lose their balance. As the agricultural machinery continues to move forward, the left roller 204 will gradually turn to the left under the yaw torque generated by the greater forward resistance, guiding the agricultural machinery to turn to the left until the forces on the two rollers 204 return to balance. This allows the agricultural machinery to move forward along the extension direction of the ridge. This makes it easier for the device to perform path calibration and guidance along the direction of the ridge, automatically calibrating the steering efficiency of the guide wheels, and facilitating the operation of the agricultural machinery on the ridge.

[0017] The upper side of the inner wall of the supporting round tube 201 is provided with a flange 205 that extends horizontally toward the axis of the supporting round tube 201. The inner wall of the rotating shaft 202 is provided with a limit rod 206. The outer wall of the limit rod 206 is fixedly connected to a limit ring 207. The limit ring 207 abuts against the bottom wall of the flange 205. A cap 208 is screwed onto the upper end of the limit rod 206. The cap 208 abuts against the top wall of the flange 205.

[0018] In this embodiment: Normal working state: The roller 204 deflects at a small angle, and the limiting rod 206 and the cap 208 are only used as safety backups and do not affect normal steering. Extreme deflection state: When the roller 204 deflects significantly due to a sharp bend in the ridge or a sudden change in terrain, the limiting ring 207 will abut against the lower end surface of the flange 205 to prevent the roller 204 from deflecting further inward. At the same time, the cap 208 will abut against the upper end surface of the flange 205 to prevent the roller 204 from deflecting excessively outward. This allows the device to easily control the maximum deflection angle of the roller 204 within a safe range through bidirectional restriction, preventing the roller 204 from completely leaving the ridge, avoiding missed tillage and seedling damage caused by the agricultural machinery "derailing", ensuring that the guide group always maintains the "ridge top centered" working state, and protecting the guide mechanism from damage in extreme terrain.

[0019] The inner walls of the crossbeam 100 are hexagonal on both the left and right sides, and the outer walls of the sleeves 101 on both the left and right sides match the inner walls of the crossbeam 100.

[0020] In this embodiment, the hexagonal shape facilitates the limiting and guiding of the movement of the sleeve 101, preventing the sleeve 101 from deflecting, and also facilitates the limiting and guiding of the adjusting block 104, preventing the adjusting block 104 from deflecting, which is beneficial for the device to perform adjustment operations.

[0021] A mounting bracket 108 is provided on the rear side wall of the crossbeam 100. The mounting bracket 108 has evenly spaced mounting holes to facilitate the insertion of fastening bolts for fixing. Sealing rings 109 are fixedly connected to both sides of the inner wall of the crossbeam 100. The sealing rings 109 facilitate the sealing of the joint and improve the sealing performance. The sleeve 101 is located on the inner wall of the sealing ring 109.

[0022] In this embodiment: the mounting bracket 108 facilitates connection and fixation with agricultural machinery using fastening bolts, and the sealing ring 109 facilitates sealing of the joint between the sleeve 101 and the crossbeam 100 to prevent leakage and prevent water from entering the field, causing corrosion and affecting the operation of the device.
