Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare seedling placing apparatus and a spare seedling placing apparatus which moves a fertilizer carrier so as to balance the weight of the body during operation. The present invention relates to a riding type transplanter provided with a platform device and a fertilizer application device. 2. Description of the Related Art Conventionally, a multi-row seedling planting section is mounted on a rear portion of a traveling vehicle body via a lift mechanism so as to be able to move up and down. 2. Description of the Related Art A transplanter (rice transplanter) is known that includes a pair of spare seedling mounting devices on which a plurality of spare seedlings can be placed, and a fertilizer that extends in the left-right direction corresponding to a seedling planting portion at a rear portion of a traveling vehicle body. ing. The spare seedling mounting table is composed of a plurality of spare seedlings vertically
When the number of seedlings in the seedling mounting portion of the seedling plant is reduced or exhausted, a spare seedling is taken out from the spare seedling mounting portion and supplied to the seedling mounting portion. Further, the fertilizer is continuously provided in the left and right direction behind the driver's seat of the traveling vehicle body, and powdery and granular fertilizer fed from the fertilizer hopper is provided at one end of the fertilizer application device. The exhaust heat from the engine is sucked and blown out and fed to the fertilizer pipe by fertilizer, and when the fertilizer in the fertilizer hopper runs out, it is replenished from the running vehicle side. When replenishing the fertilizer hopper with fertilizer or replenishing the seedling mounting table with the preliminary seedlings from the above-described auxiliary seedling mounting table, steps provided between the driving seat of the traveling vehicle body and the fertilizer application device are used. [0003] The above-mentioned spare seedling mounting device is made movable in the front-rear direction, and the spare seedling mounting device is moved back and forth in accordance with a change in the amount of seedlings in the seedling mounting portion of the seedling planting section so as to balance the longitudinal direction of the machine. A conventional rice transplanter is disclosed in Japanese Utility Model Laid-Open No. 5-46225. In addition, the spare seedling mounting table is made rotatable in the horizontal direction, and is always arranged at the front of the traveling vehicle body,
At the time of seedling replenishment, there has also been proposed one that rotates toward the seedling planting portion and approaches the seedling planting portion so that the seedling replenishing operation can be performed efficiently and easily. When there is no more spare seedling on the spare seedling mounting table, or when there is no more fertilizer in the fertilizer hopper, the front end of the running vehicle is buried (farm road).
Or stop the transplanter by approaching it parallel to the ridge, stop and supply new spare seedlings from the ridge side to the spare seedling mounting table, and also supply fertilizer into the fertilizer hopper through the steps. I am trying to do it. [0004] In the above-mentioned conventional transplanting machine, a spare seedling mounting device for supplying seedlings to the seedling mounting of the seedling planting section is provided. There was no fertilizer carrier to supply fertilizer. For this reason, if a fertilizer carrier is provided, there is a problem that it is necessary to take measures to balance the body, as in the case of the spare seedling mounting device. The present invention has been made to solve the above problems. [0005] In order to achieve the above object, the present invention provides a method for mounting a seedling planting portion at the rear of a traveling vehicle body.
In a transplanter having a spare seedling mounting device provided on the traveling vehicle body and a fertilizer application device extending in the left-right direction corresponding to the seedling planting portion at the rear portion of the traveling vehicle body, the seedling planting portion may be provided behind the seat of the traveling vehicle body. A fertilizer hopper of the fertilizer applicator is arranged on the front side, and the spare seedling rest of the spare seedling rest apparatus is moved to the front side so that the spare seedling rest is projected forward from the front end of the machine. Side so that the spare seedling mounting table is moved back and forth to a spare seedling supply position located behind the front end of the machine, and a spare fertilizer for replenishing fertilizer is placed on the fertilizer hopper. stand and fertilizer carrier and spare seedlings

Preliminary fertilizer supported on the above-mentioned spare seedling mount so that it can rotate back and forth
The rotation of the support arm enables the fertilizer carrier to move back and forth between a position above the fertilizer hopper and a position in front of the passenger car body . With the above arrangement, the transplanter equipped with the spare seedling mounting device and the fertilizer device of the present invention performs the following operations. . The spare seedling mounting device can be moved, so when seedlings are supplied from the spare seedling mounting device to the seedling mounting portion of the seedling planting section,
When replenishing the spare seedling mounting device with the spare seedling mounting device, the spare seedling mounting device is moved to easily perform the operation of replenishing the seedling mounting portion and the spare seedling mounting device of the seedling mounting portion. . Since the fertilizer carrier for holding the extra fertilizer for replenishing the fertilizer to the fertilizer hopper of the fertilizer application device is provided on the spare seedling mounting device so as to be movable together with the spare seedling mounting device, the fertilizer carrier is mounted on the fertilizer carrier. By relocating the fertilizer carrier when replenishing the fertilizer hopper with the extra fertilizer that has been placed, or when replenishing the empty fertilizer carrier with the extra fertilizer,
Fertilizer supply to the fertilizer hopper and fertilizer carrier can be easily performed. An embodiment of the present invention will be specifically described below with reference to the accompanying drawings. 1 and 2, a riding type rice transplanter 1 is equipped with a front wheel 3 and a rear wheel 4, and drives and drives the front and rear wheels 3 and 4 to drive a four-wheel drive type vehicle body (traveling vehicle body) 2.

Therefore, the worker can move across the vehicle width direction from the side steps 26, 26 through the rear step 9, and can supply fertilizer to the fertilizer hopper 10 without increasing the overall length of the passenger car body 2, and will be described later. Seedlings can be supplied to the seedling placing table 22 of the seedling planting section 6 from the spare seedling placing table apparatus. A plurality of (five in the drawing) reserve seedlings having a predetermined width and a long length in the front-rear direction are provided on the outer side along the length direction of the side steps 26, 26 in the horizontal direction. A pair of mountable spare seedling mounts 27, 27 (one of which is not shown) is supported by a pair of front and rear parallel link arms 28, 29 so as to be movable in the front-rear direction. The parallel link arms 28 and 29 are rotated back and forth by hydraulic cylinders 30 and 31, and a horizontal support arm 32 is pivotally mounted on an upper end thereof. A vertical arm 34 is connected to a front end of the horizontal support arm 32 via a motor 33. The vertical arm 34 supports spare seedling support frames 35. The spare seedling mounting table 27 is also rotatable by a predetermined angle in the horizontal direction by the hydraulic cylinder 36. A base end of a reserve fertilizer support arm 37 is supported rotatably in the front-rear direction below the lowermost reserve seedling support frame 35 of the reserve seedling mount 27. The part supports three fertilizer carriers 38 on which spare fertilizer is placed. The spare fertilizer support arm 37 can move back and forth by the expansion and contraction operation of a hydraulic cylinder 39. The fertilizer carrier 38 is movable between a position above the fertilizer hopper 10 and a position in front of the passenger car body 2 and can be stopped at an intermediate portion thereof. On both sides (only one is shown) of the driver's seat 7, a cross-shaped stepping operation element 40 and a stepping operation button 41 which are operated by the operator's foot are provided. This foot control 4
The 0 and the stepping operation button 41 are used to freely move the spare seedling mounting table 27 and the fertilizer carrier 38 back and forth, and to rotate right and left. On the other hand, a horizontal sensor 42 and a control box 43 are provided at a front portion of the passenger body 2.
During the seedling planting operation, particularly when the level of the airframe changes due to a change in the amount of seedlings on the seedling table 22 of the seedling planting section 6, this is sensed by the horizontal sensor 42 and controlled in accordance with the sensed value. The box 43 is automatically controlled to move the spare seedling mounting table 27 and the fertilizer carrier 38 to balance the machine. Further, the spare seedling mounting table 27 moves in front of the passenger car body 2 to supply a spare seedling from the ridge (farm road) side.
When moving to the seedling placement section 6 side with the spare seedlings placed thereon and moving to a spare seedling supply position where the seedling mounting base 22 can be supplied with the spare seedlings, The seedlings are rotated horizontally to make it easier to take out the spare seedlings. Similarly, the fertilizer carrier 38 can be easily moved to a position where the reserve fertilizer is supplied to the fertilizer hopper and a position where the empty fertilizer carrier 38 is supplied with the reserve fertilizer. The seedling planting section 6 can extend and retract a hydraulic cylinder (not shown) and move up and down via a lifting link 5. When the center float 20 also serving as a sensor float is in contact with the ground, the center float 20 changes the contact pressure. Upon detection, the seedling planting section 6 is automatically moved up and down. When the shift lever 19 is shifted to the retreat position, the spare seedling mounting table 27 and the fertilizer carrier 38 are moved rearward,
The front wheels 3 are prevented from sinking into the paddy fields when the aircraft is retracted. The horizontal sensor 42 and the control box 43 may be turned on only when an unillustrated planting clutch lever is engaged. Further, the moving speed of the preliminary seedling placing table 27 and the fertilizer carrier 38 is slow during automatic control by the horizontal sensor 42 and the control box 43, and is fast when operated by the foot control 40 and the foot control button 41. ing. Next, the power of the embodiment constructed as above will be described.
It is described the action of the use-type rice transplanters 1. Riding rice transplanter 1

The power is transmitted from the passenger car body 2 to the seedling planting section 6 and the fertilizer application apparatus 8 to drive, and
In the seedling planting part 6, ten seedlings are planted on the paddy surface at predetermined intervals by the rotary seedling planting bodies 23, 23,. The fertilizer fed from the feed pipe 12 of the fertilizer application device 8 is sent out toward the field by the pressure hot air sent from the blower 13 to the blower pipe, and is fertilized in the fertilizer groove opened by a groover (not shown). During the rice planting and fertilizing operations, when the horizontality of the body changes due to a change in the amount of seedlings on the seedling mount 22 of the seedling planting section 6, this is sensed by the horizontal sensor 42 and the sensed value is detected. The auxiliary seedling table 27 and the fertilizer carrier 3 are automatically controlled by the control box 43 accordingly.
8 to balance the aircraft. When the seedlings on the seedling mounting table 22 have run out or are low and need to be replenished, the traveling of the passenger car body 2 is stopped, and the seedling placement section 6 is raised as it is via the lifting link 6. Then, the driver stands backward on the rear step 9, turns backward, lifts the spare seedlings on the spare seedling mounting table 27, and replenishes the spare seedlings from the tip of the mounting table 22. When the supply of the seedlings is completed, the passenger car body 2 is driven to restart the rice planting and fertilization work.
