Description

  The present invention relates to a transplanter, and more particularly to a mechanism of a transplanter that transplants a vegetable seedling such as an onion into a cocoon.

  Conventionally, a two-row transplanter has been used to plant an onion seedling in a cocoon. However, recently, in order to improve work efficiency, transplanters have been developed that reciprocate and plant 4 onion seedlings in a cocoon. For example, Patent Document 1 discloses a four-row transplanter for reciprocating and planting four onion seedlings in a reed.

In the width direction of the stacking frame 105, a plurality of U-shaped bars 107 are provided at a predetermined interval. This bar is a member that supports the bottom surface of the irrigation tank 104.
Further, similarly to the loading frame 105, a holding frame 106 is provided that is rotatable with respect to the support member 107 and fixes the irrigation tank 104 during loading. The holding frame 106 has a U shape in plan view.

Next, a method of loading the irrigation tank 104 will be described with reference to FIGS.
As shown in FIG. 3, the loading frame 105 is stored vertically when the transplanter 10 is transported. Then, when planting the seedling 38, the stored loading frame 105 is rotated in the left-right direction so that the loading surface of the loading frame 105 becomes horizontal.
Thereafter, the irrigation tank 104 is inserted into the loading frame 105 and loaded. After loading the irrigation tank 104, the holding frame 106 is rotated to hold the irrigation tank 104. Then, the vegetable seedling 38 is planted in the cocoon 40 while supplying water or medicine from the fixed irrigation tank 104. Thereafter, planting is completed, and the stacking frame 105 is folded and stored. Thereby, it can be set as the loading frame 105 which loads the irrigation tank 104 which can be accommodated in a truck.

Next, the rolling mechanism of the vehicle body will be described with reference to FIGS.
Conventionally, the airframe is rolled by operating a valve using a hydraulic cylinder. However, a rolling mechanism using a hydraulic cylinder increases the cost of manufacturing it. Further, the use of the hydraulic cylinder complicates the layout of the operation unit.
Therefore, the rolling operation is performed using the screw 109.

  Specifically, as shown in FIG. 3, an operation box 110 is provided at an intermediate portion of the seedling stage frame 28 provided in the vertical direction from the intermediate portion of the handle frame 26. As shown in FIGS. 15 and 16, the operation box 110 is provided with a rod-shaped shaft member 112. In addition, one end of an oval rotation support member 113 is connected to one end of the shaft member 112. Further, an operation handle 111 is provided at the other end of the rotation support member 113. Thereby, the shaft member 112 is rotatably provided by the operation handle 111.

  In addition, a screw 109 that can be screwed into the operation box 110 is engraved in an intermediate portion of the shaft member 112. One end side of the first plate member 115 is pivotally connected to the intermediate portion of the shaft member 112 with the first pin 114 as a fulcrum. The other end side of the first plate member 115 is rotatably connected to the second plate member 117 and the second pin 116. Furthermore, wire ends 120 a and 120 b are provided at both ends of the second plate member 117, and one ends of two wires 121 a and 121 b are connected.

  As shown in FIG. 17, the other ends of the two wires 121a and 121b are connected to both ends of the third plate 118 through coil springs 122a and 122b. The coil springs 122a and 122b have a function of removing looseness and smoothing the behavior of the airframe during delivery of the load of the two wires 121a and 121b (right to left inclination, etc.). The third plate member 118 is rotatably provided with the third shaft portion 119 as a fulcrum.

  Further, the third shaft portion 119 is provided with a fourth star plate 124 having a three-star shape, and one end of a stay 123 is connected to the fourth plate member 124. A front wheel support shaft 18 on the front wheel 16 side and a drive case 22 on the rear wheel 17 side are rotatably connected to the other end side of the stay 123 via a predetermined member. An upper stay 186 is disposed between the front wheel support shaft 18 and the rotation support shaft 21 via a first stay support member 185 and a second stay support member 187.

Next, a method for rolling the aircraft will be described.
First, the operation handle 111 of the operation box 110 is turned clockwise, for example. Then, the screw 109 provided at the tip of the operation handle 111 is screwed. Next, the first plate member 115 rotates and the second plate member 117 also rotates. Thereafter, one wire 121a provided on the second plate member 117 is pulled, and the other wire 121b is loosened.

  Then, as shown in FIG. 14, the third plate member 118 connected to the other ends of the wires 121 a and 121 b also rotates and stays via the fourth plate member 124 connected to the third shaft portion 119. 123 is pushed forward with respect to the airframe or returned backward. Then, the front wheel support shaft 18 of the front wheel 16 and the drive case 22 of the rear wheel 17 provided on the other end side of the stay 123 rotate about the rotation support shaft 21 as a fulcrum. Thereby, one of the left and right wheels can be raised and lowered in the vertical direction. Therefore, as shown in FIG. 13, the airframe can be tilted in the left-right direction, and stable rolling can be obtained.

Next, the depth setting structure of the planting part will be described with reference to FIGS. 1 and 18 to 19.
First, the main lifting mechanism will be described. The main elevating mechanism is configured to raise and lower the machine body up and down by a hydraulic pump 77 and a hydraulic cylinder 153 on the basis of one sensor roller out of a plurality of units, thereby integrally arranging a plurality of planted bodies at a predetermined height. The actuator is fixed in position.

  Specifically, as shown in FIGS. 18 and 19, columnar sensor rollers 33a to 33c are arranged in front of the planting body. The sensor roller 33a corresponds to the first planted body 50a from the left in plan view, and the sensor roller 33b corresponds to the second planted body 50b and the third planted body 50c. Sensor rollers 33c are respectively arranged corresponding to the fourth planted bodies 50d. That is, the auxiliary lifting mechanism 35 is provided corresponding to the first planted body 50a and the fourth planted body 50d on both sides.

  As shown in FIGS. 18 and 19, the sensor rollers 33 a to 33 c are rotatably provided, and one end portions of a pair of L-shaped float frames 96 are attached to both ends of the rotation shaft 182. . A roller support frame 168 is inserted into each L-shaped float frame 96 to integrally support the sensor rollers 33a to 33c.

  The sensor roller 33 b disposed in the center is fixed to the roller support frame 168 via the float frame 96. The left and right sensor rollers 33 a and 33 c are connected to the float frame 96 and the pin 210 via the roller support frame 168 and a connecting plate 191. Accordingly, the left and right sensor rollers 33a and 33c are provided so as to be rotatable in the vertical direction with the roller support frame 168 as a fulcrum.

A substantially L-shaped roller holding frame 169 is disposed on a side portion from the roller support frame 168. One end of a planting depth adjustment rod 170 extending upward from one end of the roller holding frame 169 is connected to the roller holding frame 169. Further, one end of a rod holding member 171 is provided at the other end of the planting depth adjusting rod 170 so as to be rotatable about the pin 172 as a fulcrum. Furthermore, one end of a main elevating stay 174 is provided at the other end of the rod holding member 171 so as to be rotatable about the pin 173 as a fulcrum. The other end of the main elevating stay 174 is connected to the hydraulic valve 175.
The rod holding member 171 is provided with a planting adjustment handle 178 extending above the apertures 51a to 51d.

  As shown in FIG. 1, the transplanter 10 is provided with a hydraulic cylinder 153 that moves the machine up and down by opening and closing the hydraulic valve 175. In other words, pressure oil is received from the hydraulic cylinder 153 and the piston rod is pushed back in the longitudinal direction of the machine body. A plate-like contact member (not shown) is provided at the tip of the piston rod of the hydraulic cylinder 153. The abutting member abuts a shaft member (not shown) connected to the drive case 22 (rear wheel side) and the front wheel support 18 (front wheel side). That is, the shaft member is provided so as to be movable forward and rearward by the contact of the contact member with the shaft member, and the front wheel support 18 for the front wheel and the drive case 22 for the rear wheel are rotated. Thereby, the body can be moved up and down by the unevenness of the ridge 40.

Next, the auxiliary lifting mechanism 35 will be described.
As shown in FIGS. 18 and 19, the cylindrical sensor roller 33c is connected to the roller support frame 168 via a connecting plate 191 connected to the corners of the float frame 96 disposed at both ends thereof. And can be rotated freely.
Further, a rod-shaped sensor arm 97 extending from the roller support frame 168 in the traveling direction and having a tip bent in a substantially L shape is provided. Further, a rod-like float arm 98 extending in the width direction of the machine body is provided as a shaft portion in the bent portion 214 of the substantially L-shaped sensor arm 97.

  Further, a base end portion of an oval plate member 216 is rotatably connected to the float arm 98 about the float arm 98 as a shaft portion, and a rod-like float rod 99 is provided at a distal end portion of the oval plate member 216. A pin 215 is rotatably disposed. The float rod 99 is connected to the other end of the float frame 96 by a pin 217.

Further, the base end portion of the stay 212 is connected to the distal end portion of the sensor arm 97 whose distal end is bent in an approximately L shape by a pin 213. The tip of the stay 212 is connected to the lower part of the lifting guide 53. The stay 212 rotates the lower end portion of the elevating guide 53 around the upper end.
The auxiliary lifting mechanism disposed on the sensor roller 33a side has the same structure.

Next, the operation of the main lifting mechanism will be described. For example, as shown in FIG. 30, consider the case of a ridge 40 whose left and right strips are lower than the center.
First, the three sensor rollers 33a to 33c are initially set at predetermined height positions. The height adjustment of the three sensor rollers 33a to 33c is performed by the planting depth adjustment handle 178. Next, when the machine body is made to travel on the bag 40, the sensor roller 33b provided at the center moves up and down along the upper surface of the bag 40. Further, the roller support frame 168 that fixes and supports the sensor roller 33b also moves up and down. Further, the roller holding frame 169 provided on the side portion from the roller support frame 168 also moves up and down.

  Then, the planting depth adjustment rod 170 moves up and down, and opens and closes the hydraulic valve 175 via the rod holding member 171. Along with this, the piston rod of the hydraulic cylinder 153 is pushed forward or returned backward. Then, the front wheel support 18 for the front wheels and the drive case 22 for the rear wheels are rotated via the predetermined member. Thereby, the relationship between the aircraft and the bag can be kept constant.

Next, the operation of the auxiliary lifting mechanism will be described.
The sensor rollers 33a and 33c provided on the left and right sides are provided so as to be rotatable in the vertical direction with respect to the roller support frame. Therefore, as shown in FIG. 30, in the case of a ridge 38 having a high central portion and a low left and right side, the left and right sensor rollers 33a and 33c are positioned below the sensor roller 33b. Then, when the machine body travels on the heel 40, the sensor rollers 33a and 33c provided on the left and right sides move up and down following the upper surface of the heel 40.

That is, the sensor arm 97 connected to the float arm 98 of the sensor rollers 33a and 33c rotates up and down with the float arm 98 as a fulcrum. The float rod 99 connected to the tip of the sensor arm 97 reciprocates forward or backward.
As a result, the stay 212 connected to the tip of the sensor arm 97 reciprocates forward or backward. The stay 212 rotates the lower end portion of the elevating guide 53 around the upper end. Thereby, the apertures 51a-51d of the said planting body rotate to an up-down direction.

For example, in the case of a ridge having a convex surface, when the sensor rollers 33a and 33c are raised, the float rod 99 is returned to the rear, and the stay 212 is returned to the rear. And the raising / lowering guide 53 is also returned back. Thereby, the apertures 51a and 51d are positioned upward (E position) according to the convex surface. On the contrary, in the case of a ridge having a concave surface, the reverse movement described above is performed, and the apertures 51a and 51d are positioned downward (G position).
As a result, the planting depth of each strip can be made constant even with the ridge 40 having irregularities in the left-right direction.
In this embodiment, the central sensor roller 33b is fixed and the left and right sensor rollers 33a and 33c can be moved up and down. However, the left and right sensor rollers 33a and 33c are fixed and the center sensor is fixed. The roller 33b can also be provided so as to be movable up and down.

Next, the structure of the upper stop spring will be described with reference to FIG.
Conventionally, the planting drive shaft 125 has been pulled by a strong spring 74 in order to stop the hole-opening devices 51a to 51d of the planting body.
However, since the pulling force of the coil spring 74 is strong and the coil spring 74 is pulled at the end of the shaft (cantilever structure), the burden on the planting drive shaft 125 is large. Further, with the increase in the number of strips such as four strips, a further force for fixing the planting parts 50a to 50d at the upper part is necessary, and there has been a problem that the tensile force of the coil spring 74 must be strengthened. .
In view of this, the cylindrical body 126 provided at the intermediate portion of the planting drive shaft 125 and provided with the planting drive shaft 125 at a position where the shaft portion is eccentric is pulled by a coil spring 74 (both-end support structure).

  Specifically, as shown in FIG. 4, on the planting drive shaft 125, when viewed from the front, between the first planted body A and the second planted body B from the right. A cylindrical body 126 is provided. As shown in FIG. 20, the planting drive shaft 125 is disposed at a position eccentric from the center of the cylindrical body 126. A plate member 155 is disposed on the outer periphery of the cylindrical body 126 below the cylindrical body 126. Then, one end of each of the four coil springs 74 is connected to the plate member 155, and the other end of the coil spring 74 is fixed to a latching member 153 provided on the body frame 15 side.

  And the position of the said cylindrical body 126 is set so that the urging | biasing of the said coil spring 74 may become the minimum, when the said planting body (perforator 51a-51d) stops above. Then, the planting drive shaft 125 is pulled up by the coil spring 74 through the cylindrical body 126. Thereby, when the driving of the planted body is stopped, the hole punchers 51a to 51d of the planted body always stop at the upper part.

Next, the adjustment mechanism in the width direction of the planting body will be described with reference to FIG.
Specifically, as shown in FIG. 21, the transplant portion 13 is provided with a plurality of trumpet-shaped inheritance guide bodies 101 a to 101 d that receive seedlings and guide them downward. The inheritance guide bodies 101a to 101d have an upper end and a lower end opening and are formed in a cylindrical shape. And under the inheritance guide bodies 101a-101d, four aperturers 51a-51d are detachably provided.
Then, the center position of the lower end opening of each of the inheritance guide bodies 101a to 101d and the center position of the upper end opening of each of the aperturers 51a to 51d are shifted (biased) by a certain width in the left-right width direction. And arrange).

  Specifically, as shown in FIG. 21, the center position of the upper end opening of the first hole opening device 51a is viewed from the front with respect to the center position of the lower end opening of the transfer guide bodies 101a to 101d. For example, the position is shifted 1 cm to the left. The center position of the upper end opening of the second hole opening device 51b is shifted from the center position of the lower end opening of the inheritance guide body 101b by 1 cm, for example, when viewed from the front.

  The center position of the upper end opening of the third hole opening device 51c is shifted from the center position of the lower end opening of the transfer guide 101c by 1 cm, for example, when viewed from the front. The center position of the upper end opening of the fourth hole opener 51d is shifted from the center position of the lower end opening of the transfer guide body 101d by 1 cm, for example, when viewed from the front.

In this state, the distance between the first aperture 51a and the second aperture 51b is, for example, W ₂₁ = 200 mm. Further, the distance between the third hole opening device 51c and the fourth hole opening device 51d is, for example, W ₂₃ = 200 mm. The interval between the second opening device 51b and the third opening unit 51c is, for example, _W 22 = 240 mm. The distance between each taking over guide member 101a~101d is constant, for example _{220mm (W 11, W 12,} W 13).

  The pairs of the respective inheritance guide bodies 101a to 101d and the respective apertures 51a to 51d are detachably attached. That is, the relationship between the pair of the first opening device 51a and the transfer guide body 101a and the pair of the second opening device 51b and the transfer guide body 101b are switched. Further, the relationship between the pair of the third hole opening device 51c and the transfer guide body 101c and the pair of the fourth hole opening device 51d and the transfer guide body 101d are switched (changed).

As a result, the center position of the upper end opening of the first hole opening device 51a is shifted from the center position of the lower end opening of the inheritance guide body 101a by 1 cm, for example, to the right when viewed from the front. it can. Further, the center position of the upper end opening of the second hole opening device 51b can be provided, for example, by shifting the position of 1 cm to the left in front view with respect to the center position of the lower end opening of the transfer guide body 101b. .
The center position of the upper end opening of the third hole opening device 51c can be provided, for example, by shifting the center position of the lower end opening of the transfer guide body 101c to the right, for example, by 1 cm. The center position of the upper end opening of the fourth hole opening device 51d can be provided, for example, 1 cm away from the center position of the lower end opening of the transfer guide body 101d when viewed from the front.

In the above state, the interval between the first aperture 51a and the second aperture 51b is, for example, W ₄₁ = 240 mm. The distance between the third opening device 51c and the fourth opening device 51d is, for example, _W 43 = 240 mm. Furthermore, the distance between the second hole opener 51b and the third hole opener 51c is, for example, W ₄₂ = 240 mm.

On the other hand, the interval between the first transfer guide body 101a and the second transfer guide body 101b is, for example, W ₃₁ = 220 mm. The distance between the third inheritance guide body 101c and the fourth inheritance guide body 101d is, for example, W ₃₃ = 220 mm. Furthermore, the distance between the second transfer guide body 101b and the third transfer guide body 101c is, for example, W ₃₂ = 260 mm.
However, in this case, the positions where the seedlings are dropped with respect to the first transfer guide body 101a and the second transfer guide body 101b are shifted by, for example, W ₅₁ and W ₅₂ = 40 mm.

Therefore, the above-described deviation is corrected by advancing the advance angle at which the first and second apertures 51a and 51b rotate.
Hereinafter, the advance angle for correcting the deviation will be described.
It moves by 4 pots (293.2 mm) by one rotation of the hole opening device 51. The deviation is 40 mm. Therefore, the following formula is used to obtain the advance angle X for correcting the deviation of about 40 mm.
X = 40 (mm) /293.2 (mm) × 360 °
And X = 49 °.
That is, the advance angle of the first and second apertures 51a and 51b is advanced by 49 ° with respect to the third and fourth apertures 51c and 51d. Thereby, even if the streak interval is different, it is possible to stabilize the seedling dropped from the shutter from being inherited by the inheritance guide bodies 101a to 101c and the aperturers 51a to 51d.
The method for adjusting the advance angle is not limited. For example, it can be handled by changing the chain at the time of manufacturing or shipping.
