Description

Seedling transplanter

The present invention relates to the arrangement of various control levers in a parent implanter. In addition, the present invention relates to an operating device of a mobile farming machine, and can be used for work machines or combines mounted on a mother transplanter or a tractor.

In general, the mother implanter is provided so that the parent implant can be lifted up and down on the rear side of the driving body having a cockpit, and the mother implanter is configured to connect, block, and lift the drive of the parent transplant by operating the implant lift lever installed on the side of the cockpit. Is known. Such a parent implanter includes a peripheral gear lever for changing the shift position of a geared peripheral gear, a sub-shift lever for controlling the speed of a belt-type or hydraulic auxiliary gear, a transplant lifting lever for connecting, blocking, and elevating the driving of the parent implant. A plurality of operation levers such as a sensitivity control lever for adjusting the sensitivity of the lift control is provided. In most conventional mother implanters, the subshift lever and the transplantation lifting lever are arranged on the same left and right sides with respect to the cockpit.

When the mother transplanter is turned on the bank of the rice field, the mother transplanter is lifted to stop planting, and the moving speed of the main body of the machine is made slower than the normal transplant operation speed. In general, the mother transplanter is equipped with an automatic deceleration mechanism that automatically decelerates the moving speed when the mother transplant is raised.There is no need to operate the sub transmission lever at the start of turning. It is operated to return to normal working speed. This is to maintain a low speed between the course adjustment, the so-called seeding line alignment, to keep the seedling line straight after the end of the turn.

Therefore, at the end of the swing, the implant lifting lever is operated from the transplant blocking position to the implant linking position to align the seedling rows, and then the subshift lever is increased immediately. At this time, if the implantation lifting lever and the auxiliary shift lever are provided on the same side of the left and right sides, the hand holding the transplantation lifting lever must be moved to the auxiliary shifting lever immediately after the end of the operation, causing confusion in lever operation. have.

In addition, when the seedlings are reduced, when the seedlings are supplied to the rear transplantation unit on the traveling vehicle body, the operation levers are provided on the side of the cockpit, which may cause the operation levers to become obstacles.

On the other hand, in the operation lever of the type which has an operation positioning mechanism which interlocks a manual operation mechanism by drive of an actuator, such as an electric motor, and determines the operation position, the operation position by an actuator and the operation positioning mechanism The positioning is difficult to match exactly, and in severe cases, the positioning may not be possible.

Therefore, the present invention has a problem that, in the mother implanter of the above-described configuration, confusion of the same lever operation is unlikely to occur, and the operation lever is not obstructed at the time of seedling replenishment, and anyone can easily perform accurate lever operation. In order to achieve, it set as the structure described next.

The peripheral speed lever 60 is arrange | positioned at the left side of the front cover 30, and each shift position of "road running speed", "neutral", "transfer running speed", and "reverse speed" is provided from the front to the back. It is dangerous to accidentally make the "road running speed" at the time of transplantation work. Therefore, as shown in Fig. 3, a stopper 70 which restricts the shift to the "road running speed" may be provided. The stopper 70 rotates by manually grasping the handle 70a protruding toward the front of the operation panel 71, and controls the "road running speed" (shown in solid line) and the unregulated state (double dashed line). To the city). Since the steering wheel 70a enters inward from the outer surface of the operation panel 71 in the state where the road running speed is regulated, the front cover 30 may be worn by the operator for supplying seedlings during work in the rice field. When walking on the left side of the stopper, the handle 70a of the stopper does not become an obstacle.

The operating position of "lift", "neutral", "down" and "transfer" is set in the implantation lifting lever 62, and the lifting hydraulic valve 46 and the implantation clutch 25 are set in accordance with the operation position of the lever. Activate When the transplantation lifting lever 62 is "neutral", the hydraulic valve 46 is in a neutral state. When it is "raised", the hydraulic valve 46 is changed to raise the parent implant 4, and the "down" ”, The hydraulic valve 46 is changed to the lower side of the mother implant part 4. When the transplant part lifting lever 62 is "grafted", the parent transplant part 4 is always kept at a constant height in accordance with the change in the land height of the mother transplant part 4 detected by the center float 54. Change the hydraulic valve 46 so as to. The sensitivity of this lift control is adjusted by the sensitivity adjustment lever 64. In addition, when the implant lifting lever 62 is operated by "transplantation", the implant clutch is connected. When the implant lifting lever 62 is operated other than "transplantation", the implant clutch is blocked. In addition, in the example of FIG. 5, each operation position of the implantation lifting lever 62 is positioned by the combination of the positioning cam 78 and the roller 79 caught by the cam. A detection sensor 80 for detecting the position of the implant lifting lever 62 and a motor 81 for rotating the implant lifting lever 62 are provided. When the finger lever 75 is operated, a position corresponding thereto is provided. The implantation lifting lever 62 is moved until the operation. When the transplantation lifting lever 62 is operated manually, the implantation lifting lever 62 is slid in the axial center direction of the lever shaft 62a, This is performed after disconnecting the sensor 80 and the motor 81. In addition, the implantable lifting lever 62 can be expanded and contracted, so that the implantable lifting lever 62 can be shortened to prevent other operations from becoming cumbersome at the time of the implantation work with little operation.

The sub transmission lever 63 is provided on the left side of the cockpit 29, and the sub transmission 23 can be shifted in multiple stages, for example, in four stages. Normally, the speed is set to be higher than the "lowest speed" when going straight in the paddy field, and "lowest speed" when turning. Apart from the operation of the sub transmission lever 63, an automatic deceleration mechanism is provided for rapidly reducing the sub transmission 23 to the "lowest speed" in conjunction with the rise of the mother implant part 4.

Regarding the lever arrangement of the mother implanter, the peripheral speed lever 60 and the sub transmission lever 63, which are operating levers for adjusting the moving speed of the machine body, are located at the left and right centers of the cockpit 29 on the left side, The implant lever lifting lever 62 and the finger lever 75, which are operating levers for connecting, blocking, and lifting the negative drive, are disposed at the right and left centers of the cockpit 29. The throttle lever 61 is an operation lever for adjusting the moving speed of the main body of the machine. However, the throttle lever 61 is an exception because the throttle lever 61 is not used during the implantation operation.

In the transplantation operation, the mother implanter 1 maintains the mother implantation unit 4 at a height at which the floats 54 and 55 are grounded to drive the mother implantation unit 4, and at the same time, maintains the main body of the machine at an appropriate speed. In this way, seedlings are transplanted to the mud surface stopped by the floats 54 and 55. After transplanting to the rice paddy, the finger lever 75 or the transplantation lifting lever 62 is rotated upward to raise the parent implant 4 while driving stop. As the parent implant portion 4 rises, the subshift automatically decelerates to "lowest speed." Then, the steering wheel 11 is operated to rotate the machine main body.

When the turning is finished, the transplantation operation is resumed by operating the finger lever 75 with the right hand finger or the implant lifting lever 62 with the right hand while holding the steering handle 11. Immediately after the end of the turning, the steering wheel 11 is operated to align the course of the main body of the machine with the line drawn on the paddy field by the conductive line marker 53, so that the alignment is performed. Then, when the alignment is completed, the subshift lever 63 is operated by the left hand to increase the speed up to the moving speed before turning. In this way, since the right hand holds the steering wheel 11 from the start of the swing to the end of the swing, the swing can be safely and reliably performed. In addition, since the finger lever 75 or the implantable lifting lever 62 and the sub transmission lever 63 are operated by separate left and right hands, a quick lever operation can be performed.

In addition, the parent implant 4 is interlocked by the implant transmission shaft 26 by the engine 20.

Various operation apparatuses are arranged on the main frame 15. In addition to the implant lifting lever 62 for elevating the parent implant 4 with respect to the main frame 15, the engine 20 is located on the side of the cockpit 29. ), The sub-shift lever 123 continuously shifts the belt-type sub transmission 23 from the transmission case 12 to the input shaft of the transmission case 12, and the lowering of the mother implant portion 4 by the lifting hydraulic cylinder 45. By moving the elevating control valve 125 crosswise by vertical movement of the locking lever 124 and the float 54 and 55 which are fixed and fixed, A lift sensitivity adjusting lever 126 or the like for adjusting the sensitivity of the lift control for raising and lowering 4) is disposed. In addition, a back lift lever 127 is provided below the cockpit 29 to automatically lift the parent implant 4 when the main frame 15 is retracted.

Further, in the vicinity of the steering wheel 31 and the front cover 30, the main clutch pedal 66 for operating the main clutch in the transmission case 12, or the rear wheel brake pedal 67L for braking the left and right rear wheels 11, 67R), the throttle lever 61 for manipulating the throttle of the engine 20, the lever 75 for raising and lowering the mother implant part 4 at short intervals, and the peripheral gears in the transmission case 12 are operated. The peripheral speed lever 60 etc. which are deceived are arrange | positioned.

In such a mother implanter, the implantation lifting lever 62 is driven by a motor 81. The shaft which is installed on the bracket 152 which is a constituent member integral with the main frame 15 by the pinion 133 which is the operation drive mechanism 102 and the rack gear 134 which are geared by the motor 81 of the motor ( 135) Rotate freely around. In addition, the shaft 135 is provided so that the positioning cam 136 integral with the implantable lifting lever 62, which is a manual operation mechanism, can freely rotate. The cam roller 138 of the swinging arm 137 is provided in contact with the outer circumferential portion of the positioning cam 136 so that the rotational position of the positioning cam 136 can be fixed or released in a freely rotating state. Reference numeral 139 denotes an axis of the swing arm 137 and 140 denotes a spring for elastically applying the cam roller 138 toward the positioning cam 136.

The cam arm 141 is integrally installed on the implant lifting lever 62, and the cam arm 141 is connected to the clutch by pressing the cam of the implant clutch which transmits power to the parent implant 4. You can block it. Moreover, the valve arm 142 is provided in this implantation part lifting lever 62, and presses the spool of the lifting control valve 125 to change the parallel links 40 and 41 from the neutral position to the down position or the up position. Can be operated.

A pin 145 constituting the positioning flow mechanism 104 and the pin 145 are sandwiched between the arm 143 of the implant lifting lever 62 and the positioning cam 136 and the integral arm 144. The long hole 146 is installed. The pin 145 is fixed to the arm 144, and the long hole 146 is formed in the arm 143. The position of the relationship between the rack gear 134 and the positioning cam 136 on the shaft 135 is inserted through the flow gap formed by the pin 145 and the long hole 146 between these arms 144 and 143. Since the rotational position of the positioning cam 136 with respect to the rack gear 134 can move back and forth, the engagement of the positioning cam 136 and the cam roller 138 will be engaged in a fixed position. For this reason, the position of the implantation lifting lever 62 is fixed to the correct position by the positioning cam 136 and the cam roller 138, and the position of the implantation lifting lever 62 by the control of the motor 81 is fixed. Hunting can be prevented.

At this time, since the cam roller 138 acting on the positioning cam 136 is pressed by the elastic force of the spring 140, the positioning cam 136 driven by the motor 81 to a predetermined position is a pin ( Since only the long hole 146 into which the 145 is fitted is rotated in advance, the positioning cam 136 is pre-positioned to prevent hunting more effectively.

Such operation of the operating mechanism by the motor 81 is performed by the output from the controller 147. The operation switch 148, the sensor switch 149, the control program 150, and the like are input to the input side of the controller 147. The operation switch 148 may be caused by the operation of the lever 75, the control output 150 may be turned off of the engine switch 155, and in the case of the sensor switch, the back lift lever 127 may be used. ), The reverse position sensor 149 input of the retraction control. In addition, the operation position is a potentiometer (151) for detecting the rotational position of the rack gear 134 is installed on the bracket 152, the arm 153 is rotated integrally with the rack gear 134 and freely stretched.

In operation by the implant lifting lever 62, the clutch cam arm 141 and the valve arm 142 are rotated to operate the implant clutch and the lift control valve 125 to operate the neutral position N. Can be switched to the lowering implant blocking position (A) and the lowering implant connecting position (B), or the raising position (C), and at each of these positions N, A, B, and C, each of the positioning cams 136 The cam roller 138 is engaged at the alignment position. At this time, even if the pinion 133 is rotated by the rotation of the rack gear 134, the motor 81 is freely rotated. In addition, since the potentiometer 151 is also rotated, the operation position can be input to the controller 147 and displayed.

That is, in the neutral position N, the parent implant part 4 is not raised and lowered, and the implant clutch to the parent implant part 4 is also interrupted | blocked. In the descending implant blocking position A, the parent implant 4 is lowered, but the implant clutch is blocked so that transplantation is not possible. In the descending implant linking position B, the parent implant 4 is lowered and the implant clutch is connected to allow implantation. Moreover, in the raised position C, the mother implant part 4 raises to a non-transplantation position, and this implant part clutch is also in the state which was interrupted | blocked.

In the case of the operation switch 148, when the lever 75 is operated, the motor 81 is intermittently output from the controller 147 every time the lever 75 is raised upward. ), The valve arm 142, the positioning cam 136 and the like are rotated in the upward direction by one pitch. This one pitch is set as each engagement position interval of the cam roller 138 in this positioning cam 136. As shown in FIG. On the contrary, each time the lever 75 is pushed downward, the valve arm 142, the positioning cam 136, and the like are rotated in the downward direction by one pitch.

Next, when the back lift lever 127 is operated to the connecting position as the case of the sensor switch, the reversing position sensor 149 detects that the peripheral speed lever 61 has been operated to the reverse position. ) Is driven to change the lift control valve 31 to the raised position (C).

In addition, as the control output 150 causes the engine switch 155 to be turned OFF, the motor 81 is driven to change the elevating control valve 125 to the neutral position N, thereby changing the parent implant portion 4. Set it to neutral position. Thereby, the implantation lifting lever 62 is always in the neutral position N at the time of engine startup, and it is possible to prevent the mother implantation unit 4 from suddenly driving or lifting at the time of engine startup.

In addition, when the mother transplant part 4 is moved up and down by the ground of the floats 54 and 55, and the mother implant depth is controlled to be constant, the motor 81 is formed at the lower implant part connecting position B. It is carried out by the structure of a system different from the case by the drive of.

Engage the cam roller 138 from the positioning cam 136 by operating the back lift lever 127 at the connecting position D and the peripheral speed lever 60 at the forward position F to the reverse position R. FIG. The alignment is released, and the positioning cam 136 and the parent implant lifting lever 62 are rotated to the raised position C by the elastic force of the spring 156. As a result, the elevating control valve 125 is changed to the raised position C, and the elevating control valve 125 is set to the most elevated position by the elevating hydraulic cylinder 45. At this time, the positioning cam 136 is returned to the neutral position N, the cam roller 138 is engaged with this neutral position N, and the implantation part lifting lever 62 is moved to this neutral position N. FIG. In this way, the hunting of the lifting control valve 125 is eliminated, and the position of the implant lifting lever 62 is assured.

The actuating arm 158 is rotated by the arm 157 at the beginning of the peripheral speed lever 60 so that the swinging arm 137 of the positioning cam 136 is spring-loaded through the back lift cable 159. Retracted against 160, the cam roller 138 can be pulled out of engagement of the positioning cam 136. An arm 162 for fixing an outer cable 161 on the outside of the back lift cable 159 is installed to freely rotate on the same shaft 163 as the back lift lever 127, and a spring 164 By this it is elastically pushed toward the connection position (D) of the back lift lever 127. The back lift lever 127 is integrally engaged with the fixed piece 165.

By rotating the back lift lever 127 from the connecting position D to the blocking position E, the arm 162 is rotated against the spring 164 to connect the connecting lift cable 166 to the lower end thereof. The rotating arm 167 provided in the member integrally with the main frame 15 can be rotated through this. This rotating arm 167 is engaged with the engagement flange 169 integral with the piston 168 so as to be rotated by the expansion and contraction of the lifting hydraulic cylinder 45. Also, the clutch cam arm 141 and the auto return rod 170 are connected to the pivot arm 167.

In such a configuration, when the back lift lever 127 is moved back to the connecting position D and the peripheral speed lever 60 is set to the reverse position R, the cam roller 138 is moved through the back lift cable 159. It is taken out of the positioning cam 136. As a result, the positioning cam 136 is rotated by the spring 156 to press the lifting control valve 125 to change to the rising position C. FIG. Then, the lifting hydraulic cylinder 45 is extended to raise the implanter 15. By this rise, the engagement flange 169 of the elevating cylinder 113 rotates the pivot arm 167 to resist the lift cable 166 against the spring 164 to relax the back lift cable 159. This presses the cam roller 138 of the flow arm 137 onto the positioning cam 136 by the spring 160. At the same time, the pivoting lifting lever 62 and the positioning cam 136 are returned from the raised position C to the neutral position N through the auto return rod 170 by the rotation of the rotation arm 167 and the cam roller ( 138) is engaged and fixed.

Thus, even when the peripheral speed lever 60 is in the reverse position R, the cam roller 138 is engaged with the positioning cam 136 to maintain the lifting control valve 125 in the neutral position N. FIG.

The third embodiment will be described differently from the above example mainly in accordance with FIG. Since the sensitivity of the elevating control valve 125 is controlled by the sub transmission lever 123, it becomes insensitive in the high speed driving region. Between the implantation lifting lever 62 and the sub transmission lever 123 on the lever shaft 135, a sensing arm 171 which cooperates with the vertical movement of the floats 54 and 55 is provided, and the sub transmission lever 123 is provided. Is operated at the high speed position H, the spring 172 and the pin 173 of the sub transmission lever 123 are opened from the sensing arm 171 to strengthen the elastic force of the spring 172, and thus the sensing arm 171 Increase the working load of) to make the sensitivity dull. As a result, a simple and inexpensive configuration can be achieved by sensitivity control in conjunction with the vehicle speed.

When the sensing arm 171 rotates against the spring 172 by the transplantation lifting lever 62, the lifting control valve 125 is pressed to lift the implant device 105, and conversely, rotates toward the spring 172. It will descend. The sensing arm 171 is interlocked with the floats 54, 55 and the cable 174. When the float 110 is rotated upward, the cable 174 is pulled out, and the sensing arm 171 is rotated to the raised position. When the sub transmission lever 123 is operated in the low speed region, the spring 172 is relaxed, and the sensitivity returns to the normal sensitive region. 175 is a rod connected to the sub transmission lever 123, and is connected to allow the stepless transmission by the belt-type sub transmission 23.

The fourth embodiment will be described differently from the always-described embodiment mainly with reference to Figs. 13 and 14. By pulling the lower locking lever 124 in the operation panel 176 on the side of the cockpit 29 upward, the lowering position of the parent implanted part 4 is fixed, and other than the lower locking lever 124. Manipulation is not to be lowered manually or automatically. The lifting control valve 125 is provided below the operation panel 176, and the lower locking pin 177 protrudes above the operation panel 176.

The lower locking lever 124 may rotate up and down around the lever shaft 178. When the lower locking pin 177 is pushed down by the adjustment bolt 179 integrated with the lower locking lever 124, the lifting control valve The lowering circuit in 125 is closed so that the lifting hydraulic cylinder 45 is not reduced. 180 is a push spool.

As described above, the mother implanter according to the present invention has an operation lever for driving, connecting and lifting the mother implant, and an operation lever for adjusting the moving speed of the main body of the mother, which is arranged on the left and right, so that the confusion of lever operation is avoided. It is difficult to produce, and furthermore, it is possible to operate the two system levers at the same time or with a short time difference with both the left and right hands, and the operability of the lever is improved.

In addition, since the operating lever is operated in conjunction with the operation of the operation tool, during the mother transplant operation, the operation can be carried out by operating the operation tool in the front to improve the workability. When the worker replenishes the hair to the hair transplantation part while moving from the cockpit or moving to the side of the cockpit, the length of the operation lever can be shortened so as not to interfere with the hair replenishment work, so that the hair replenishment work can be performed comfortably. In addition, when directly operating the operation lever, the length of the operation lever may be changed to directly operate the lever.

On the other hand, in the present invention, when the operation drive mechanism is driven to a predetermined position by the drive of the actuator, the operation positioning mechanism fixes the operation position of the operation mechanism. At this time, when accurate positioning by the operation positioning mechanism is performed, the positioning flow mechanism can be operated to position at this operation corresponding position. For this reason, the linkage between the operation drive mechanism and the operation positioning mechanism can be made smoothly, and the operation positioning can be performed accurately and reliably.
