[0021] In order to better understand the purpose, structure and function of the utility model, a travel assist device of the utility model is further described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown, a stroke assisting device of the utility model includes a mounting plate 1 arranged on the side wall of the radish machine clamping frame 19, the mounting plate 1 extends outward on the radish machine clamping frame 19, and a support frame 3 is arranged on the mounting plate 1, and the support frame 3 is arranged obliquely downward relative to the mounting plate 1. At the same time, a bracket plate 5 is rotatably arranged on the support frame 3 through a rotating shaft 4, a through hole is opened on the bracket plate 5 for the rotation shaft 4 to pass through, and a baffle is arranged at the outer end of the bracket plate 5, and the baffle is connected to the rotating shaft 4 through a bolt to play the role of the baffle in limiting the bracket plate 5. Among them, the free end of the bracket plate 5 is arranged obliquely downward toward the position of the mounting plate 1, and a torsion spring 7 is sleeved on the rotating shaft 4 between the bracket plate 5 and the support frame 3, and the support frame 3 and the bracket plate 5 are connected by the torsion spring 7. A roller 6 is also rotatably arranged at the free end of the bracket plate 5, and a travel rod 9 is rotatably arranged on the bracket plate 5, and a control frame 12 is arranged on the travel rod 9. At the same time, a limit buckle 10 for the travel rod 9 to slide is provided on the support frame 3. The setting of the limit buckle 10 can make the travel rod 9 move vertically, and a proximity sensing switch is provided on the support frame 3. The control frame 12 cooperates with the proximity sensing switch, and the proximity sensing switch is connected to the radish machine cylinder.

[0023] Specifically, the proximity sensor switch is arranged on the support frame 3 through a bracket, and the support frame 3 is composed of a connecting plate 13 and a support plate 14, the connecting plate 13 is arranged on the support frame 3, and the support plate 14 is vertically arranged on the top surface of the free end of the connecting plate 13. The proximity sensor switch arranged on the bracket includes a first sensor head 15 and a second sensor head 16 arranged on the support plate 14. The first sensor head 15 and the second sensor head 16 are arranged diagonally on the support plate 14. The control frame 12 matched with the proximity sensor switch includes a base 121 arranged on the travel rod 9, and a vertical plate 122 is arranged on the side wall of the base 121, and a first sensor plate 123 and a second sensor plate 124 are arranged on the vertical plate 122, and the first sensor plate 123 and the second sensor plate 124 are arranged corresponding to the first sensor head 15 and the second sensor head 16 respectively, and the first sensor plate 123 and the second sensor plate 124 are located between the first sensor head 15 and the second sensor head 16.

[0024] The radish machine lowers the radish machine clamping frame 19 and the spiral rod group arranged on the clamping frame (19) into the ditch through the oil cylinder, and the mounting plate 1 arranged on the clamping frame (19) will also be lowered, and the bracket plate 5 arranged on the mounting plate 1 through the support frame 3 drives the roller 6 to contact the ditch. When a bulge appears in the ditch, the roller 6 moves upward along the bulge with the rotating shaft 4 as the midpoint through the bracket plate 5. When the bracket plate 5 rotates, the torsion spring 7 is twisted, and the travel rod 9 on the bracket plate 5 is driven to move upward, and the control frame 12 on the travel rod 9 will also move upward, and the first sensing plate 123 and the second sensing plate 124 on the control frame 12 will be lifted upward through the base 121 and the vertical plate 122, and the first sensing head 15 on the proximity sensing switch will detect the approach of the first sensing plate 123. At this time, the first sensing head 15 sends a signal to the oil cylinder through the electromagnetic valve to supply oil, so that the radish machine clamping frame 19 is lifted upward. When the carrot machine clamping frame 19 is lifted upward, the support frame 3 on the mounting plate 1 is lifted upward, and the support frame 3 rotates relative to the bracket plate 5 through the rotating shaft 4, and the torsion spring 7 releases the torque. At the same time, the support frame 3 also drives the proximity sensor switch to move upward, and when the first sensor head 15 is lifted away from the first sensor plate 123, the oil cylinder stops supplying oil.

[0025] Similarly, when a pit appears in the ridge, the roller 6 descends through the support plate 5 with the rotating shaft 4 as the center, and drives the travel rod 9 on the support plate 5 to move downward. The travel rod 9 drives the first induction plate 123 and the second induction plate 124 on the control frame 12 to descend and makes the second induction plate 124 close to the second induction head 16. At this time, the second induction head 16 senses the second induction plate 124 and sends a signal to the oil cylinder through the solenoid valve. The oil cylinder starts to unload oil and drives the radish machine clamping frame 19 to descend. When the radish machine clamping frame 19 descends, it will drive the support frame 3 to descend through the mounting plate 1. The support frame 3 will also rotate with the rotating shaft 4 and the support plate 5 when it descends. When the support frame 3 descends, the proximity sensor switch on the support will also descend. After the second induction head 16 on the proximity sensor switch is away from the second induction plate 124, the oil cylinder stops unloading oil, and the work of moving the radish machine clamping frame 19 downward can be completed. In this way, the oil cylinder can achieve the work of accurately adjusting the height of the radish machine clamping frame 19.

A through hole is provided on the seat 121, and the through hole on the seat 121 can be inserted into the travel rod 9, and the through hole and the travel rod 9 are in clearance fit. At the same time, a first nut 11 is threadedly connected on the first thread 91 on the travel rod 9, so that the control frame 12 can be easily disassembled. During disassembly, the first nut 11 can be unscrewed from the first thread 91 of the travel rod 9, and then the control frame 12 can be disassembled from the first thread 91 of the travel rod 9, which is simple to operate and easy to use. Among them, a traction frame 8 is provided at the bottom end of the travel rod 9, and the traction frame 8 is rotatably connected to the bracket plate 5. At the same time, a second thread 92 is provided at the bottom end of the travel rod 9, and the travel rod 9 and the traction frame 8 are detachably threadedly connected. In this way, the disassembly and assembly of the travel rod 9 and the traction frame 8 are convenient for installation.

[0027] Preferably, a connection frame 2 is provided at one end of the support frame 3 relative to the rotating shaft 4, and a mounting hole is provided on the connection frame 2, and a bolt 18 and a second nut 181 matched with the bolt 18 are provided in the mounting hole. A slide groove 17 corresponding to the limiting bolt 18 is provided on the mounting plate 1, and the mounting hole is symmetrically arranged with respect to the center of the connection frame 2, and the slide groove 17 is also symmetrically arranged with respect to the center of the mounting plate 1, and the slide groove 17 and the through hole are limited by the bolt 18 and the second nut 181. When the connection frame 2 needs to be moved, the second nut 181 on the bolt 18 can be loosened, and then the connection frame 2 can be moved to a suitable position of the mounting plate 1, and the second nut 181 and the matched bolt 18 can be tightened again to complete the position fixation of the connection frame 2 on the mounting plate 1.
