  The present invention relates to a planting transmission device for transmitting a seedling planting device via a forward / reverse transmission, an inconstant speed transmission mechanism, etc., and a planting transmission device for a seedling planting machine that prevents the phenomenon of squeezing up the seedling planting part. About.

As a planting transmission device, a technology for transmitting a seedling planting device from a belt-type continuously variable transmission through a one-way clutch, a stock change gear, a planting clutch, etc. (see, for example, Patent Document 1), and a claw A technique (for example, refer to Patent Document 2) for transmitting a seedling planting apparatus from a clutch-type planting clutch via an inconstant speed transmission gear mechanism or the like is known.
JP-A-11-346512 (first page, FIG. 3). Japanese Unexamined Patent Publication No. 2000-312514 (first page, FIG. 4).

In traveling transmission and seedling planting transmission using a forward / reverse transmission such as a hydraulic continuously variable transmission (HST), a single shift lever is used to move from a forward position through a neutral position to a reverse position. Therefore, the seedling planting device does not stop immediately even if there is an erroneous operation of switching from the forward position to the reverse position immediately after passing the neutral position, or even when switching to the reverse position. This often leads to overrun transmission. Such a phenomenon is that when the transmission by the transmission device is at a constant transmission speed, the timing of planting stop by cutting the planting clutch is easily stabilized, but the eccentric gear is used for loose planting. In the form in which the planting clutch is disengaged in the stroke after passing through the inconstant speed transmission mechanism, etc., the planting stop timing is likely to change slowly and becomes unstable. For this reason, it is easy to produce the phenomenon of raising in the transmission of a seedling planting apparatus.

The invention according to claim 1 is provided on the vehicle body (11) by connecting the seedling planting device (7) to the rear side of the vehicle body (11) having wheels (24, 25) via a lift link (13). The power is transmitted from the engine (31) to the transmission case (28) through the forward / reverse transmission (1), and transmitted from the transmission case (28) to the wheels (24, 25) and the seedling planting device (7). It is to seedling planting apparatus planting device (7) (3) is configured to transmission through the non-uniform speed transmission mechanism (2), and the forward-reverse shifting at transmission upstream side than the non-uniform transmission mechanism (2) The seedling transplanter is characterized in that a one-way clutch (4) is provided on the lower transmission side of the device (1) . The seedling transplanter is driven by the engine (31) to travel through the forward / reverse transmission (1), and from the one-way clutch (4) to the inconstant speed transmission mechanism (2). The seedling planting device (7) is planted by being transmitted to the attaching device (3) . Here, when the forward / reverse transmission (1) is operated from the forward position to the neutral position, the forward travel of the vehicle body (11) stops and the seedling planting device (3) also stops. When operated from the neutral position to the reverse position, reverse travel is performed and the seedling planting device (3) passing through the one-way clutch (4) is maintained in a transmission stop state .

According to the second aspect of the present invention, the seedling planting device (3) passes through the one-way clutch (4) , the inter-strain transmission mechanism (5) , the planting clutch (6) , and the unequal speed transmission mechanism (2 ). and seedling planting machine according to claim 1, characterized in that the transmission to. The seedling planting device (3) is operated in an interlocked manner from the one-way clutch (4) through the inter-strain transmission mechanism (5) , the planting clutch (6) , the inconstant speed transmission mechanism (2), and the like. By operating the forward / reverse transmission (1) to the reverse position, the transmission to the seedling planting device (3) is stopped by stopping the reverse transmission of the one-way clutch (4) . Moreover, when stopping the transmission of the seedling planting device (3) , it is possible to stop the interlocking of the inconstant speed transmission mechanism (2) by disengaging the planting clutch (6) . In particular, this planting clutch (6) often uses a fixed position stop clutch configuration, but in this configuration, the planting device (3) can be stably stopped at a fixed position.

The invention according to claim 3, by operating the forward-reverse shift device (1) in the reverse position, not to increase the NaeUe device (7), planting clutch for transmission to the NaeUe device (7) ( The seedling transplanter according to claim 1 or 2, further comprising backlift means (8) for linking and interlocking 6) . By operating the forward / reverse transmission (1) from the neutral position to the forward position or the reverse position, the forward transmission or the reverse transmission can be performed. In this reverse travel, when the backlift means (8) is in the on state, the seedling planting device (7) is raised to the non-planting position and the planting clutch (6) is disengaged to perform the reverse travel. Make it smooth. Further, when the backlift means (8) is switched to the cut-off state, the planting clutch (6) is cut off simultaneously with the reverse travel, but the seedling planting device (7) is not raised and maintained at the seedling planting position. Is done. For this reason, a vehicle body can be moved backward with the attitude | position which lowered | hung the seedling planting apparatus (7) . In such transmission, since the stop position of the planting device (3) is stabilized by cutting the planting clutch (6 ) , planting claws of the seedling planting device (3) are caused by transmission overrun and scooping phenomenon. Etc. can be prevented from being damaged by being strongly driven into the floor or the ground.

  In the first aspect of the invention, since the one-way clutch 4 has a constant rotation, when the one-way clutch 4 stops the reverse rotation transmission state, the inconstant speed transmission mechanism 2 is brought into a stationary state, The overrun of the stop position of the seedling planting device 3 due to this interlocking can be suppressed, the stop position can be stabilized at a constant position, and the seedling raising phenomenon of the seedling planting device 3 can be prevented.

  According to the second aspect of the present invention, the pulsation of the inconstant speed transmission mechanism 2 is difficult to be transmitted due to the transmission load from the one-way clutch 4 through the inconstant speed transmission mechanism 2, and the overrun interlocking when the one-way clutch 4 is disengaged. It can be suppressed accurately. Moreover, when the transmission by the planting clutch 6 is cut off, the pulsation effect by the inconstant speed transmission mechanism 2 of the seedling planting device 3 can be reduced, and the stop timing of the seedling planting device 3 can be stabilized. In the form of the stop clutch 6, the stop at a fixed position can be stabilized.

  The invention according to claim 3 can retract the seedling planting device 7 in a state where it is lowered with respect to the vehicle body. The planting clutch eliminates the overrun when the planting clutch 6 is disengaged and the crunching phenomenon of the seedling planting device 3 by the non-uniform speed transmission mechanism 2. Supporting the stop at a fixed position by 6 can reduce damage caused by the collision of the seedling planting device 3 with the ground or floor surface.

  Based on the drawings, the seedling planting machine 7 is connected to the rear side of the vehicle 11 in the riding four-wheel drive mode via a lift link 13 in the form of a parallel link that is lifted and lowered by hydraulic expansion and contraction of the lift cylinder 12.

  The interlocking mechanism from the engine 21 to the wheels 24 and 25, the seedling planting device 7 and the like includes a hydraulic continuously variable transmission (HST) 1, a transmission mechanism in the transmission case 28, and transmissions in the front and rear axle housings 29 and 30. It is configured to be interlocked via a mechanism, a transmission mechanism in the PTO transmission case 31, and the like. The hydraulic continuously variable transmission 1 is driven by the belt 32 from the engine 21 and drives the HST input shaft 33 to move the trunnion shaft 34 from the neutral position N to the forward position F or the reverse position R by the HST lever 35 on the side of the driver's seat 20. By rotating, the HST output shaft 36 can be continuously variablely rotated from the neutral position to the forward side and the reverse side. The belt 38 is transmitted between the HST output shaft 36 and the input shaft 37 of the mission case 28.

  The transmission mechanism of the transmission case 28 is interlocked with a transmission gear 39 that is geared from the input shaft 37 and shifts to a high and low speed, and further transmits the rear axle 41 via a rear differential gear 40 and a gear in the rear axle housing 30. At the same time, the vehicle can travel by being transmitted through the front axle 43 through the front differential gear 42 and the gears in the front axle housing 29. Further, the input shaft 37 transmits the PTO interlocking shaft 44, the PTO shaft 14 and the like through a one-way clutch (reverse rotation prevention clutch) 4. In the one-way clutch 4, a clutch gear 45 that is meshed and rotated from an input shaft 37 and a clutch metal 47 that is pushed by a spring 46 are arranged along the clutch shaft 48. The claw 49 is engaged with the opposite surface of the claw 49 in the forward rotation direction F and integrally rotates, and in the reverse rotation direction R, the clutch metal 47 is moved in the axial direction against the spring 46 to disengage and engage with the claw 49. It has a directional clutch configuration. A PTO transmission gear 51 that is switched by a shifter 50 is provided on the clutch shaft 48, and is transmitted to the PTO interlocking shaft 44 via the gear shaft 52. As described above, when the input shaft 37 is rotated in the forward direction via the one-way clutch 4, it is not transmitted to the PTO interlocking shaft 44, but is not transmitted to the PTO interlocking shaft 44 when rotated in the reverse direction.

  In the PTO transmission case 31, a straight change gear type inter-strain transmission mechanism 5, an inconstant speed transmission mechanism 2, a planting clutch 6 and the like are provided, and the input rotation from the PTO interlocking shaft 44 is planted. It is configured to be able to output and rotate to the PTO shaft 14 to the apparatus 3 and to be transmitted from the inter-strain transmission mechanism 5 to the sub PTO shaft 53 to an attached work device such as a fertilizer application device. A pair of transmission gear shafts 54 and 55 are mounted on the PTO transmission case 31, and multistage transmission gears 56 and 57 are provided on the shafts 54 and 55, and a shifter 58 is provided along the transmission gear shaft 55. The speed change shaft 54 can be changed in speed by selecting the speed change gear 57 that is engaged by the speed change key 65 that can be moved at the same time. Between the transmission shaft 54 and the PTO shaft 14 that is rotatable around the rear periphery of the transmission shaft 55, a pair of eccentric gears 59, 60, eccentric gears 61, 62 with different transmission ratios are provided. By switching the shift key 64 moved by the shifter 63 along the transmission gear shaft 54, the transmission is switched between the inconstant speed transmission by the eccentric gear 59 and the inconstant speed transmission by the eccentric gear 61. Can be transmitted. When the seedling planting device 3 is transmitted by these unequal speed transmission mechanisms 2, the seedling planting claws 19 set the seedling separating claw 19 from the seedling tank 18 at the ascending position, and the descending position with respect to the soil surface. The speed of the seedling planting process is activated as a rapid speed to perform accurate seedling planting. The planting clutch 6 is pressed by a spring 66 on the rear end surface of the transmission gear 56 on the transmission shaft 54 and can be engaged in a claw engagement form. The planting clutch 6 can be turned off against this.

  A throttle lever 71 is provided on the side of the dashboard 22, and a main transmission lever 72 that switches the transmission gear 39 is disposed. On the side of the driver's seat 20, an HST lever 35 that shifts the hydraulic continuously variable transmission 1, a planting lift lever 73 that lifts and lowers the seedling planting device 7, a backlift lever 8 that serves as backlift means, and the like are disposed. The The planting elevating lever 73 has a fan-shaped rack 74 that is integrally rotated, and is repelled by a spring 70 so as to rotate to the rear raising position A side. The spool 76 of the hydraulic pressure switching valve 75 of the lift cylinder 12 hydraulic circuit is brought into contact with the rear side of the fan rack 74, and the lift switching valve 75 is switched by rotating the fan rack 74. The seedling planting device 7 is lifted and lowered. The fan-shaped rack 74 is provided with an engagement arm 78 that is pressed and engaged by a spring 77 so that the switching operation position of the planting elevating lever 73 can be fixed or released. In this unlocked state, the sector rack 74 is rotated by the force of the spring 70, and the spool 76 is pushed and switched to the raised position A. The planting lift lever 73 transmits the seedling planting device 7 at the raising position A for raising the seedling planting device 7 to the non-seedling planting position, the lowering position B for lowering near the soil surface, and the lowering position. The operation can be switched to the seedling planting position C where the work is performed. A cam arm 79 is integrated with the lower end portion of the sector rack 74 and connected to a bell crank arm 81 between the lift cylinder 12 via a rod 80. A clutch pin 67 of the planting clutch 6 is arranged.

  The backlift lever 8 is switched and guided by forming a long insertion hole 83 and a short cut hole 84 in the front and rear of the lever guide. When the back lift lever 8 is connected to the engagement pin 82 via the wire 85 and is operated to the entry hole 83, the back lift lever 8 retracts the engagement pin 82 from the rotation area of the cam arm 79, 73 can be operated to the raised position A, and when operated to the cut hole 84, the engaging pin 82 protrudes into the rotation area of the cam arm 79, and the planting lift lever 73 can be operated to the lowered position B. The position A is set so that it cannot be operated. The lever guide 88 of the HST lever 35 is provided with a rotating arm 89. By operating the HST lever 35 to the reverse position R, the rotating arm 89 is rotated outward. The engagement arm 78 can be detached from the sector rack 74 by pulling the wire 90 and the rod 91 that are connected to each other. As a result, when the hydraulic continuously variable transmission 1 is operated to the reverse position R, the fan-shaped rack 74, the planting lift lever 73 and the lift valve 75 by the spring 70 are switched to the lift position A. Raised to position. The back lift operation of the raising position A operation of the seedling planting device 7 at the reverse position R is such that the back lift lever 8 is operated to the entry hole 83 and the rotation of the sector rack 74 by the engaging pin 82 is restricted. Performed in the released state. When the backlift lever 8 is operated to the cut hole 84, the rotation range of the sector rack 74 is restricted by the engagement pin 82. Therefore, the HST lever 35 is set to the reverse position R and the engagement arm 78 is moved. Even if it is removed from the fan-shaped rack 74, the raising / lowering valve 75 is not switched to the raised position A, and the seedling planting device 7 can be positioned at the lowered position B.

  The bell crank arm 81 is rotated by the lift and lift of the lift cylinder 12 and is connected to the lower end portion of the arm 94 which is coaxial with the back lift lever 8 via the wire 93 and is connected to the upper end of the arm 94. By engaging the front end of the rod 91 and pulling the wire 93 through the arm 94 and the rod 91, the engagement arm 78 can be engaged with the sector rack 74 and maintained. Further, the rotation of the bell crank arm 81 operates to rotate the sector rack 74 and the planting lift lever 73 through the rod 80 toward the lowered position B against the spring 70. 75 is a turn signal provided on the left and right of the seedling tank 18. 96 is a seedling reduction sensor provided in each seedling tank 18, and 97 is a sensor float, which is configured to be small between the floats 16 and 17.

  During normal seedling planting operation, the back lift lever 8 is operated to the entry hole 83 to disengage the engaging pin 82 from the rotation range of the cam arm 79 of the sector rack 74 and the planting lift lever 73 is moved to the lowered position B. When operated, the seedling planting device 7 is lowered to the seedling planting position. The clutch pin 67 is moved upward by the rotation of the cam arm 79 so that the planting clutch 6 stopped at a fixed position is engaged, and the seedling planting device 7 is in a state of being transmitted. When the HST lever 35 is operated to the forward position F here, the input shaft 37 is transmitted to drive the front and rear wheels 24 and 25, and the one-way clutch 4, the inter-gear transmission mechanism 5, the planting clutch 6, and the inconstant speed. The seedling planting device 7 is transmitted through the transmission mechanism 2 and the like to plant seedlings.

When steering and turning at the seedling planting end, etc., the planting lift lever 73 is moved to the raised position A to switch the lift valve 75 to raise the seedling planting device 7 so that the turning operation is possible. Can do.
Here, when the HST lever 35 is operated to the reverse position R during the seedling planting operation, the rotating arm 89 is rotated outward, and the engaging arm 78 is detached from the sector rack 74 via the wire 90, the rod 91, and the like. Is done. The fan rack 74, the planting lift lever 73, and the like are rotated by the spring 70, the lift valve 75 is switched to the raised position A, and the seedling planting device 7 is raised.

Further, the engagement pin 67 is pushed by the rotation of the cam arm 79 integrated with the sector rack 74, so that the planting clutch 6 enters the disengaged position, and the transmission of the seedling planting device 7 is stopped.
Next, when the back lift lever 8 is operated to the cut hole 84, the engaging pin 82 is in a state in which the rotation of the cam arm 79, the planting elevating lever 73, the sector rack 74, etc. can be restricted, and the elevating valve 75 is moved. The seedling planting device 7 is not raised by restricting to the lowered position B. For this reason, even if the HST lever 35 is set to the reverse position R and the turning arm 89 is turned outward to disengage the engaging arm 78, the restriction of the sector rack 74, the planting lift lever 73, etc. is not released. The seedling planting device 7 can be moved backward in a lowered state.

  The transmission device to the seedling planting device 3 is transmitted from the hydraulic continuously variable transmission 1 and the one-way clutch 4 through the strain transmission mechanism 5, the planting clutch 6, and the inconstant speed transmission mechanism 2 in this order. From the above, even when the one-way clutch 4 is in constant rotation and the hydraulic continuously variable transmission 1 is switched from the forward position F to the neutral position N or further to the reverse position R, an overrun or seedling planting device The 3 part scooping phenomenon can be prevented. And the planting clutch 6 can be turned off in a state where the transmission is stabilized at a constant speed, and the stop of the seedling planting device 3 can be stabilized. The pulsation due to the transmission load of the inconstant speed transmission mechanism 2 is hardly transmitted, and the operation of the one-way clutch 4 and the raising / lowering operation of the seedling planting device 3 can be stabilized.

  Next, the difference from the above example mainly based on FIG. 7 is that the power steering circuit 98, the HST charge circuit 99 of the hydraulic continuously variable transmission 1, and the lift cylinder 12 are related to the hydraulic rotation of the hydraulic continuously variable transmission 1. The lift circuit 100 is provided in series, and prevents the charge pressure to the HST charge circuit 99 from becoming insufficient when the seedling planting device 7 is raised. A small amount throttle mechanism is added even at the fully opened position U of the seedling planting device 7 lift valve 75 to eliminate the shortage of the HST charge pressure. A throttle S is provided at the fully open position U of the lift valve 75, and this is communicated to the HST charge circuit 99 by the supply circuit 102. T is a tank port, P is a hydraulic pump, and 103 is a power steering cylinder of the power steering circuit 98. The power steering cylinder 103 is switched through the power steering circuit 98 by the operation of the steering handle 23. In the hydraulic continuously variable transmission 1, the HST pump 105 and the HST motor 106 are arranged in the HST circuit 104, and the flow direction and flow rate of the hydraulic pressure are controlled by the rotation direction and rotation angle of the trunnion shaft 34. Rotation output is performed. The HST charge circuit 99 replenishes the HST circuit 104 with a constant amount of oil at all times.

  Next, the difference from the above example mainly based on FIG. 8 is that in the seedling planting machine, when the farm field becomes deep water, it becomes easy to disturb the adjacent seedling planting line. In addition, a small and light sensor float 97 is provided so as to rise according to the water depth so that the water depth can be detected. When deep water is detected, the HST lever 35 of the hydraulic continuously variable transmission 1 or the engine is thereby detected. The accelerator or throttle lever 71 for controlling the rotation of the engine 21 is configured in an interlocking manner. This reduces the water flow and maintains a good seedling planting posture. When detecting deep water by the vertical movement of the sensor float 97 with respect to the floats 16 and 17, the vehicle body 11 is driven at a low speed, and when detecting shallow water, the control is interlocked so as to run at a high speed. The rotation angle of the sensor arm 111 that has the sensor float 97 and is rotated up and down is read by the potentiometer 112 and input to the controller 113, and the solenoids 114 and 115 that regulate the operation angle of the HST lever 35 and the throttle lever 71 are output. Control. Reference numeral 116 denotes an arm axis at the center of rotation of the arms 117 and 111 of the floats 16, 17 and 97, and is configured on the same axis.

  Next, the difference from the above example mainly based on FIG. 9 is that when the seedling reduction sensor 96 of each seedling tank 18 detects that the seedling reduction in the tank 18 has reached a certain level, both left and right are passed through the controller 113. The blinker 95 is turned on to notify the operator. Since the decrease of seedlings is notified using the blinker 95, a special notification lamp is not required, and it can be easily notified to an auxiliary worker at a far shore or the like. In addition, when an auxiliary worker carries out planting work in a state where the tank 18 is loaded with a seedling for replenishing seedlings, the auxiliary worker often faces the rear where the tank 18 is located. The blinker 95 provided on the planting device 7 side can be easily visually recognized, and the decrease in seedlings can be immediately known.

  Next, the difference from the above example mainly based on FIGS. 10 and 11 is that the center float 16 moves up and down relative to the seedling frame 15 via a link mechanism such as a float rod 121 and a float arm 122 and a spring 123. Connected to the wire 124, interlocked with the lift valve 75, and detected that the soil surface is deep by the movement of the center float, the lift valve 12 is switched to raise the seedling planting device 7 with the lift cylinder 12, On the contrary, when the soil surface is detected as being shallow by the downward movement of the center float 16, the raising / lowering control is performed so as to maintain the seedling planting depth constant by switching the elevator valve 75 and lowering the seedling planting device 7. It is configured to do.

  The arm pin 125 that supports the intermediate portion of the float arm 122 is supported by the lower portion of the bracket 127 that locks the outer portion 126 of the wire 124. A pair of left and right float arms 122 are provided, and a float rod 121 is connected to one end of the float arm 121 by a link pin 128. The upper end of the spring 123 is connected to the lower end of the wire 124, and the lower end is connected to one end of the float arm 122. The spring 123 is expanded and contracted by the vertical movement of the float 16, and a spring case 129 that surrounds the entire length or a part of the spring 123 is attached along the inside of the bracket 127 to guide the expansion and contraction operation of the spring 123. When the spring 123 falls, the wire 124 may be bent and the seedling planting device 7 may not be lowered. However, the above structure prevents the spring 123 from falling and the wire 124 from being bent, thereby improving the soil depth sensing accuracy. Increase planting accuracy. Further, since the three sides of the spring 123 are surrounded by the spring case 129 and the remaining one of the spring 123 is opened, maintenance of the spring 123 and the wire 124 can be facilitated from this open side.
