The rotary cultivator is a cultivating machine for finishing the operations of cultivating and harrowing. The soil breaking machine has the characteristics of strong soil breaking capacity, flat ground surface after ploughing and the like, so that the soil breaking machine is widely applied; meanwhile, the stubble buried below the ground surface can be cut up, the operation of the seeder is convenient, and a good seedbed is provided for later-stage seeding. The existing rotary cultivator mostly adopts double gear boxes to respectively provide power for the front wheel and the rear wheel, when the rotary cultivator needs to be switched to a reverse gear state, the control levers of the two gear boxes need to be respectively regulated and controlled, and the operation is complex.
In view of this, the present invention provides a gear shifting device, and fig. 1 to 2 illustrate an embodiment of the present invention.
Referring to fig. 1, the gear shifting device includes a speed adjusting device 1, a gear shifting member 2 and a driving structure 3, the speed adjusting device 1 includes two gearboxes 101, one gearbox 101 is used for adjusting the speed of a front wheel of the rotary cultivator, and the other gearbox 101 is used for adjusting the speed of a rear wheel of the rotary cultivator; the shift member 2 comprises a first shift lever 201 and a second shift lever 202, and the first shift lever 201 and the second shift lever 202 are respectively rotatably mounted on the two gearboxes 101 to switch the neutral state and the reverse state of the two gearboxes 101; the driving structure 3 comprises a rotating shaft 301, the rotating shaft 301 is rotatably mounted on any one of the gearboxes 101, two connecting parts 4 are mounted on the periphery of the rotating shaft 301, the two connecting parts 4 extend along the radial direction of the rotating shaft 301, an angle is formed between the two connecting parts 4, and the two connecting parts 4 are respectively movably connected with the first shift lever 201 and the second shift lever 202; the rotating shaft 301 has a first state for synchronously driving the two gearboxes 101 to the neutral state and a second state for synchronously driving the two gearboxes 101 to the reverse state on the moving stroke.
The technical scheme of the utility model in, through rotating axis of rotation 301 is installed two on the axis of rotation 301 connecting portion 4 respectively with two on the gearbox 101 first shift pole 201 with second shift pole 202 swing joint, then rotate during the axis of rotation 301, through two connecting portion 4 can drive first shift pole 201 with second shift pole 202 rotates in step, thereby can be to two gearbox 101 carries out synchronous shift, can be through the rotation axis of rotation 301 synchronous regulation two gearbox 101 to neutral state or reverse gear state.
Further, drive portion 5 is still installed to the periphery of axis of rotation 301, drive portion 5 follows axis of rotation 301's radial direction extends, drive portion 5 and two all be the angle setting between connecting portion 4. Because two connecting portion 4 respectively with first shift lever 201 with second shift lever 202 swing joint is difficult for realizing through direct drive arbitrary connecting portion 4 the rotation of axis of rotation 301 is easily blockked by first shift lever 201 or second shift lever 202 establish in addition on the axis of rotation 301 one with two connecting portion 4 are the drive portion 5 that the angle set up, drive portion 5 with axis of rotation 301 directly links, and then direct manipulation drive portion 5 is to when axis of rotation 301 rotates, can not receive first shift lever 201 with the blockking of second shift lever 202, it needs to be said that this embodiment drive portion 5 along the length that axis of rotation 301 radial direction extends is greater than two connecting portion 4 along the length that axis of rotation 301 radial direction extends to improve the moment of drive portion 5, thereby can use less power just can carry out the gear shift operation to two the gearbox 101 simultaneously.
Further, the driving structure 3 further comprises a shift knob 302 and an elastic member 304, the shift knob 302 is configured to be movably mounted on the rotary cultivator, a pull rope 303 is mounted between the shift knob 302 and the driving portion 5, and the shift knob 302 is configured to drive the rotating shaft 301 to move from the first state to the second state; the elastic member 304 is sleeved on the periphery of the pulling rope 303, and two ends of the elastic member 304 are respectively connected with the pulling rope 303 and any one of the gearboxes 101, so as to drive the rotating shaft 301 to move from the second state to the first state. When the gear shifting is not performed, under the action of the elastic member 304, the pull rope 303 pulls the driving portion 5 to make the rotating shaft 301 always be in the first state, and when the gear shifting is required, the pull rope 303 is driven by the gear shifting handle 302 to move, and the pull rope 303 drives the driving portion 5 to move, so as to drive the rotating shaft 301 to rotate, thereby completing the gear shifting.
Further, referring to fig. 1 and fig. 2, the gear shifting device further includes a limiting member 6, the limiting member 6 is provided with a limiting groove 601 penetrating in the front-back direction, the limiting groove 601 extends in the up-down direction, and the gear shifting handle 302 is correspondingly installed in the limiting groove 601; the limiting member 6 is further provided with a retaining groove 602 along the front and rear direction, and the retaining groove 602 is communicated with the upper end of the limiting groove 601, so as to accommodate the gearshift handle 302 when the gearshift handle 302 is located at the upper end of the limiting groove 601; when the shift knob 302 moves from the lower end of the limiting groove 601 to the upper end of the limiting groove 601, the rotation shaft 301 is driven to move from the first state to the second state. Since the elastic member 302 is released when the shift knob 302 is adjusted to place the two gearboxes 101 in the reverse gear state under the action of the elastic member 304, the elastic member 304 drives the two gearboxes 101 to be switched to the neutral gear state, and therefore the limiting member 6 is provided to place the shift knob 302 in the anti-backlash groove 602 when the shift knob 302 switches the two gearboxes 101 to the reverse gear state, and the anti-backlash groove 602 can prevent the shift knob 302 from moving.
Specifically, the retaining groove 602 is recessed downward. By providing the retaining groove 602 recessed downward, both sides and the lower end of the shift knob 302 can be abutted by the retaining groove 602, and the shift knob 302 can be secured in the retaining groove 602 by the elastic member 304.
Referring to fig. 1 again, the pulling rope 303 is installed at an end of the driving portion 5 away from the rotating shaft 301. By connecting the pull rope 303 to the end of the driving portion 5 away from the transmission shaft, the force for controlling the pull rope 303 to rotate the rotation shaft 301 decreases as the pull rope 303 is farther from the rotation shaft 301, and the operation becomes more labor-saving.
Further, the driving unit 5 and the rotating shaft 301 are integrally provided with the two connecting units 4. Through setting up drive division 5 axis of rotation 301 and two connecting portion 4 is integrative to be set up, can improve stability and fastness between a plurality of connected parts, wherein, drive division 5 axis of rotation 301 and two can be integrative casting moulding between connecting portion 4, also can be mutual weld forming.
