Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery repair, specifically an agricultural machinery repair support device. Background Technology

[0002] To facilitate maintenance of the underside of agricultural machinery, an auxiliary support structure is needed to raise it so that maintenance workers can enter under the machinery to carry out maintenance work. However, the existing support structure has a low lifting height and a relatively simple function, resulting in limited operating space for operators and making it difficult to carry out targeted maintenance.

[0003] The workbench for repairing agricultural machinery parts disclosed in announcement number CN215881569U improves the operating space for repair personnel by setting up a workbench with freely adjustable height and protecting it with guard bars to prevent parts from falling, thus improving safety. However, this solution has the following drawbacks: 1. The distance between the two workbenches needs to be adjusted in advance. Once the agricultural machinery is moved to the workbench position, it is impossible to make subsequent adjustments according to the actual placement or repair position of the agricultural machinery; 2. The workbench lacks a mechanism for fixing the agricultural machinery. The agricultural machinery may move during the repair process, affecting repair efficiency and even causing safety hazards. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model adopts an agricultural machinery maintenance support device, which solves the problems of fixed working space and lack of fixing means in the existing agricultural machinery maintenance platform.

[0005] The technical solution is an agricultural machinery maintenance support device, including a base with a groove at the top. A slider that can slide back and forth is set at both ends of the groove. A vertical plate is fixed on both the front and back sides of the top end of each slider. Multiple sets of rollers are set between the two vertical plates on each slider. All rollers are arranged at equal intervals and are located in the same horizontal plane. A horizontal beam in the left-right direction is set above each slider between the two vertical plates. The two ends of the beam are fixedly connected to the left and right ends of the groove. Multiple U-shaped rods with downward openings are set on each beam. The horizontal bar of the U-shaped rod is located at the interval of the rollers. The parallel bars of the U-shaped rod are located above the horizontal beams on the front and back sides. The U-shaped rod can only move up and down and can be fixed in any position. When the U-shaped rod is at the bottom of its movement path, its upper end is lower than the roller.

[0006] The lower end face of the settling tank is a sloping surface that is higher in the middle and lower at the front and back. A support plate is fixed in the middle of the settling tank. A lead screw is rotatably connected between the support plate and the front and rear end faces of the settling tank. The lead screw is parallel to the lower end face of the settling tank and can rotate. The lead screw passes through the slider and is connected to the slider by a thread to form a lead screw structure.

[0007] The base has motors fixed to its front and rear ends respectively, and the motor shaft and lead screw are driven by gear meshing.

[0008] Multiple hydraulic cylinders are fixed on the crossbeam. The number and position of the hydraulic cylinders correspond one-to-one with the parallel rods of the U-shaped rod. The piston rods of the hydraulic cylinders at corresponding positions on the front and rear sides are respectively fixedly connected to two parallel rods of the same U-shaped rod. An inlet pipe is provided on the crossbeam. The left end of the inlet pipe passes through the left end face of the base. A first inlet hole corresponding to each hydraulic cylinder is provided on the upper side of the inlet pipe. The first inlet hole is connected to the lower cavity of the hydraulic cylinder. An inner sleeve is provided inside the inlet pipe. The right end of the inner sleeve is sealed and a compression spring is provided between it and the right end face of the inlet pipe. The outer edge of the inner sleeve is sealed and fitted to the inner edge of the inlet pipe. A second inlet hole corresponding to each first inlet hole is provided on the upper side of the inner sleeve. Under the action of no external force, the second inlet hole is located to the left of the first inlet hole and is not connected to it.

[0009] The roller shaft is rotatably connected to the vertical plate and a first gear is fixed at the outer end of the roller shaft. A second gear is provided between every two first gears. The second gear meshes with the first gears on the left and right sides respectively. A motor is fixed on the vertical plate near the outer side. The motor shaft passes through the vertical plate and is coaxially fixedly connected to one of the roller shafts.

[0010] The base has a conveyor belt at each of its left and right ends. The inner height of the conveyor belt is greater than the outer height, and the height of the upper inner surface is not lower than the upper surface of the vertical plate.

[0011] The upper surface of the vertical plate near the inner side is provided with a clearance groove, and when the U-shaped rod moves down to the lowest point, its horizontal bar can be placed in the clearance groove.

[0012] This utility model has the following advantages over the prior art:

[0013] 1. This utility model improves the existing agricultural machinery repair platform by setting multiple sets of U-shaped rods on the original support to replace the support of agricultural machinery. It can stably fit the lower end face of agricultural machinery of different specifications and shapes through segmented movement, which greatly improves the support stability and adaptability.

[0014] 2. By setting an inner sleeve to control the flow of liquid into and out of the hydraulic cylinder, the U-shaped rod can be fixed after its position is determined, and the fixing method is simple and efficient;

[0015] 3. By setting the lead screw at an angle, the slider can separate from the agricultural machinery as it moves outward, avoiding friction that causes the agricultural machinery to deviate and improving the safety factor;

[0016] 4. By replacing the supports, the spacing between the front and rear vertical panels can be changed at any time according to the needs of the workspace, greatly improving practicality. Attached Figure Description

[0024] Depend on Figures 1 to 6 The present invention includes a base 1, with a recess 2 at the upper end of the base 1. A slider 3 capable of sliding back and forth is provided at the front and rear ends of the recess 2. A vertical plate 4 is fixed on the front and rear sides of the upper end of each slider 3. Multiple sets of rollers 5 are arranged between the two vertical plates 4 on each slider 3. All rollers 5 are arranged at equal intervals and located in the same horizontal plane. A horizontal beam 6 in the left and right direction is provided above each slider 3 between the two vertical plates 4. The two ends of the beam 6 are fixedly connected to the left and right ends of the recess 2. Multiple U-shaped rods 7 with downward openings are provided on each beam 6. The horizontal rods of the U-shaped rods 7 are located at intervals between the rollers 5. The parallel rods of the U-shaped rods 7 are located above the beams 6 on the front and rear sides. The U-shaped rods 7 can only move up and down and can be fixed in any position. When the U-shaped rod 7 is at the lower end of its movement path, its upper end is lower than the rollers 5.

[0025] The lower end face of the settling tank 2 is an inclined surface that is higher in the middle and lower at the front and back. A support plate 8 is fixed in the middle of the settling tank 2. A lead screw 9 is rotatably connected between the support plate 8 and the front and rear end faces of the settling tank 2. The lead screw 9 is parallel to the lower end face of the settling tank 2 and can rotate. The lead screw 9 passes through the slider 3 and is connected to the slider 3 by a thread to form a lead screw structure.

[0026] The base 1 has motors fixed to its front and rear ends respectively, and the motor shaft and the lead screw 9 are driven by gear meshing.

[0027] Multiple hydraulic cylinders 10 are fixed on the crossbeam 6. The number and position of the hydraulic cylinders 10 correspond one-to-one with the parallel rods of the U-shaped rod 7. The piston rods of the hydraulic cylinders 10 at corresponding positions on the front and rear sides are respectively fixedly connected to two parallel rods of the same U-shaped rod 7. An inlet pipe 15 is provided on the crossbeam 6. The left end of the inlet pipe 15 penetrates the left end face of the base 1. A first inlet hole 16 corresponding to each hydraulic cylinder 10 is provided on the upper side of the inlet pipe 15. The first inlet hole 16 is connected to the lower cavity of the hydraulic cylinder 10. An inner sleeve 17 is provided inside the inlet pipe 15. The right end of the inner sleeve 17 is sealed and a compression spring is provided between it and the right end face of the inlet pipe 15. The outer edge of the inner sleeve 17 is sealed and fitted to the inner edge of the inlet pipe 15. A second inlet hole 18 corresponding to each first inlet hole 16 is provided on the upper side of the inner sleeve 17. Under the action of no external force, the second inlet hole 18 is located to the left of the first inlet hole 16 and is not connected to each other.

[0028] The roller shaft 5 is rotatably connected to the vertical plate 4 and a first gear 11 is fixed at the outer end of the roller shaft 5. A second gear 12 is provided between every two first gears 11. The second gear 12 meshes with the first gears 11 on the left and right sides respectively. A motor is fixed on the vertical plate 4 near the outer side. The motor shaft passes through the vertical plate 4 and is coaxially fixedly connected to one of the roller shafts 5.

[0029] The base 1 has a conveyor belt 13 at each of its left and right ends. The inner height of the conveyor belt 13 is greater than the outer height, and the height of the upper inner surface is not lower than the upper surface of the vertical plate 4.

[0030] The upper surface of the vertical plate 4 near the inner side is provided with a relief groove 14, and the U-shaped rod 7 can be moved down to the lowest point so that its horizontal bar can be placed in the relief groove 14.

[0031] In use, this invention first positions the two sliders 3 at the center of the settling trough 2, with all U-shaped rods 7 at the bottom. At this point, the upper end of the roller shaft 5 is higher than the crossbar of the U-shaped rod 7. The water supply pipe is then connected to the left opening of the inlet pipe 15. Next, the agricultural machinery requiring repair is moved to the position of the conveyor belt 13. The conveyor belt 13 moves and lifts the machinery to the top of the roller shafts 5 on both the front and rear sides. Then, the motor on the vertical plate 4 is started, causing all the roller shafts 5 to rotate synchronously, thus conveying the machinery until it reaches the center. The position is determined, and then positive pressure liquid is injected into the inlet pipe 15 through the water supply pipe. The positive pressure liquid overcomes the spring force and drives the inner sleeve 17 to move to the right, so that the first inlet hole 16 and the second inlet hole 18 are connected. The liquid can enter the hydraulic cylinder 10 through the first inlet hole 16 and the second inlet hole 18, causing the piston rod to drive all the U-shaped rods 7 to move upward until the U-shaped rods 7 below the agricultural machinery contact the agricultural machinery and stop moving upward. The liquid supply continues, and the U-shaped rods 7 on the left and right sides of the agricultural machinery continue to move upward a certain distance before the supply stops. The water supply pipe is removed, and the inner sleeve 17 returns to its original position to the left under the action of the compression spring. The first inlet hole 16 and the second inlet hole 18 are disconnected and misaligned. All hydraulic cylinder 10 chambers are resealed, and the position of the U-shaped rod 7 is locked. Finally, the motors on the front and rear sides of the base 1 are started, causing the motors to drive the lead screw 9 to rotate. The lead screw 9 drives the two sliders 3 to move outward synchronously. Since the movement path of the sliders 3 is diagonal, the roller 5 decreases in height and disengages from the agricultural machinery after moving outward with the sliders 3. At this time, the load-bearing component is replaced by the U-shaped rod 7. The vertical plate 4 moves outward to free up space in the middle of the base 1, making it easier for operators to access and maintain the lower side of the agricultural machinery through the space between the U-shaped rods 7. After maintenance, simply reverse the motor to drive the lead screw 9, causing the slider 3 to return to the center and replace the U-shaped rods 7 to support the agricultural machinery again. Then, press the inner sleeve 17 to the right to reconnect all the first liquid inlet holes 16 and the second liquid inlet holes 18, allowing the liquid in the hydraulic cylinder 10 to flow out. All the U-shaped rods 7 can then return to their original positions under gravity, facilitating the next use of the device.

[0032] This utility model improves the existing agricultural machinery repair platform by setting up multiple sets of U-shaped rods 7 to replace the support of agricultural machinery on the basis of the original support. It can stably fit the lower end face of agricultural machinery of different specifications and shapes through segmented movement, which greatly improves the support stability and adaptability. At the same time, by replacing the support, the spacing between the front and rear vertical plates 4 can be changed at any time according to the needs of the work space, which greatly improves the practicality.
