Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a transplanter with a fertilizer application device such as a riding fertilizer rice transplanter.

[0002]

2. Description of the Related Art Conventionally, some transplanters with this type of fertilizer application have an auxiliary seedling stand placed at a lateral position on the front of the machine and a fertilizer tank provided in the space below the stand. However, in this case, since the supplementary seedlings placed on the auxiliary seedling mounting table cover the upper part of the fertilizer supply port formed in the upper part of the fertilizer tank, the fertilizer tank should be placed outward when supplying fertilizer. It is desirable to rotate it so that the upper part of the fertilizer supply port can be opened.

[0003]

However, in the prior art, since the fertilizer tank is mounted so as to be pivotally movable outward with the vertical axis on the front end side as a fulcrum, the fertilizer tank is moved forward as the pivot operation is performed. However, it is difficult to replenish the fertilizer from the driver's seat, and since the connection position of the hose connected to the bottom of the fertilizer tank is near the rotation fulcrum, the fertilizer tank can be rotated. As a result, the base end of the hose may be twisted and the durability of the hose may be reduced.

[0004]

SUMMARY OF THE INVENTION The present invention has been made with the object of providing a transplanter with a fertilizer application that can solve these problems in view of the circumstances as described above. At the lateral position of the part, an auxiliary seedling table for placing supplementary seedlings is arranged, and a fertilizer tank for storing paste fertilizer is provided on the side surface of the machine in the space below the auxiliary seedling table. With a fertilizer applicator that is installed along the posture, and the other end of the flexible hose that is connected to the bottom of the fertilizer tank is connected to the fertilizer pump that is located inside the machine behind the fertilizer tank. In the transplanter, the fertilizer tank is assembled so that the front side of the tank can be rotated outward with the vertical axis on the rear end side of the tank as a fulcrum, and the hose connection position of the fertilizer tank is set to the middle position or the front side position of the tank bottom. Set to A. In other words, when the fertilizer tank is rotated, the fertilizer tank is displaced rearward, so that the fertilizer can be replenished from the driver's seat side. Since the entire mandrel bends with little twisting and follows the turning operation of the fertilizer tank, the durability of the hose can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a traveling machine body of a riding type fertilizer rice transplanter. An operating unit 3 having a driver's seat 2 is formed at a substantially central portion of the traveling machine body 1, and an engine (not shown) is provided in front of the operation unit 3. No.) is mounted, while the planting part 5 is connected to the rear of the plant via a lifting link mechanism 4. The planting section 4 includes a seedling placing table 6 for placing the planted seedlings, a plurality of planting claws 7 for scraping the planted seedlings from the seedling placing table 6 and planting them on the rice field, and sliding on the rice field. The float 8 and the like are used, but the basic configuration of each of them is the same as the conventional one.

Reference numeral 9 denotes auxiliary seedling mounts provided on the left and right sides of the front of the machine body. The auxiliary seedling mounts 9 are the machine frame 1a.
A frame 9 of a generally U-shape that stands upright from the side of the machine
a is provided with seedling mounting portions 9b projecting outwardly in three steps, and thus, seedlings for supply for replenishing the seedling mounting table 6 are provided in six steps in total. It can be stored neatly in 9b.

Reference numeral 10 denotes a fertilizer tank disposed in a space below the auxiliary seedling table 9 (only the space below the left auxiliary seedling table 9 in this embodiment) along the side surface of the machine. 10 is for storing paste fertilizer, but a flexible hose 11 is connected to the bottom surface of the tank, and the other end side of this hose 11 is behind the fertilizer tank 10 and inside the fuselage. It is connected to the fertilizer pump 12 arranged on one side. That is, fertilizer tank 1
The pasty fertilizer stored in No. 0 is sucked into the fertilizer application pump 12 through the hose 11 and the indicator 13
Through the branch pipe 14 which intervenes therewith, reaches the corresponding position of each planting claw 7, and is discharged into the soil from the fertilizing nozzle 15 arranged at that position.

Reference numeral 16 denotes a boss portion integrally provided at the rear end portion of the fertilizer tank 10 in the vertical direction, and the boss portion 16 is provided so as to project from the rear end portion of the auxiliary seedling stand 9. It is rotatably fitted and assembled to the vertical axis portion 17a of the support shaft member 17. That is, when the fertilizer tank 10 normally located below the auxiliary seedling stand 9 is rotated outward with the vertical axis portion 17a as a fulcrum, the fertilizer supply port formed on the upper surface of the fertilizer tank 10 Since the upper part of 10a is opened, it is possible to replenish the fertilizer without being disturbed by the replenishing seedlings placed on the auxiliary seedling placing table 9. Fertilizer tank 10 with shaft 17a as a fulcrum
Since the front side of is rotated outward, the fertilizer tank 10 is displaced rearward as a whole, and as a result, the operator can replenish the fertilizer while the operator is on the operation unit 3 without getting off the vehicle. It is like this. In addition, 1
Reference numeral 8 denotes a spring hook provided at the front end portion of the tank. The spring hook 18 is detachable from an engagement shaft 19 provided at the front end side of the auxiliary seedling stand 9 and engages with the engagement shaft 19. In the combined state, the fertilizer tank 10 is locked in a normal posture along the side surface of the machine body.

In the fertilizer tank 10, the connecting position of the hose 11 is set to the intermediate position or the front position of the tank bottom. That is, when the fertilizer tank 10 is rotated outward with the rear end side as a fulcrum, the hose 11 connected to the intermediate position or the front side position of the tank bottom is entirely supported by the connection part on the fertilizer pump 12 side as a fulcrum. In order to follow the turning operation of the fertilizer tank 10 by bending,
The durability of the hose 11 can be improved as compared with a hose that is partially twisted.

The hose 11 connected to the bottom of the fertilizer tank 10 always passes through the inner side of the vertical axis portion 17a to reach the fertilizer pump 12 in plan view while the fertilizer tank 10 extends outward. In the rotated state, the piping path of the hose 11 is set so as to pass through the outside of the vertical axis portion 17a in plan view. That is, since the distance between the tank-side connection position of the hose 11 and the pump-side connection position does not change significantly in accordance with the tank rotation operation, it is possible to prevent a large pulling force from acting on the hose 11, and at the same time, to hose the hose 11. The amount of bending of 11 can be minimized.

On the other hand, reference numeral 20 is a nozzle gauge for adjusting the nozzle depth of the fertilizer application nozzle 15. The nozzle gauge 20 is a plate material provided with gauge holes 20a at predetermined intervals. However, at the time of non-adjustment, it can be integrally set on the upper link 4a constituting the lifting link mechanism 4. That is, a pair of bolt shafts 21 are preliminarily provided in the upper link 4a so as to correspond to the intervals of the gauge holes 20a. If the gauge holes 20a are inserted through the bolt shafts 21, the wing nut 2
Since the nozzle gauge 20 can be fixed with the la, the loss of the nozzle gauge 20 can be effectively prevented, and there is an advantage that it can be used immediately at the time of adjustment.

In the structure configured as described above, the fertilizer tank 10 which is normally located below the auxiliary seedling table 9 is rotated outward with the vertical axis portion 17a as a fulcrum when supplying the fertilizer. Although the upper part of the mouth 10a is opened, the fertilizer tank 10 rotates outward with the vertical axis portion 17a located on the tank rear end side as a fulcrum, so that the fertilizer tank 10 is displaced rearward as a whole. It will be. Therefore, the operator can replenish the fertilizer without getting off the vehicle one by one while being on the operation unit 3, and as a result, the workability in replenishing the fertilizer can be improved.

Moreover, in the fertilizer tank 10,
Since the connection position of the hose 11 is set to the intermediate position or the front side position of the tank bottom, the hose 11 bends as a whole with the connection part on the fertilizer pump 12 side serving as a fulcrum, so that the fertilizer tank 10 can be rotated. As a result, it is possible to eliminate the disadvantage that the durability of the hose 11 is deteriorated, such as the case where the hose is partially twisted.

Further, the hose 11 is normally passed through the inward side of the vertical axis portion 17a in plan view, and the fertilizer pump 12
On the other hand, in the state where the fertilizer tank 10 is rotated outward, while passing through the outside of the vertical axis portion 17a in plan view, the distance between the tank-side connecting position of the hose 11 and the pump-side connecting position is the tank. It is possible to avoid a large change due to the turning operation, and as a result, it is possible to prevent the disadvantage that a large pulling force acts on the hose 11, or it is possible to minimize the amount of bending of the hose 11.

However, in the prior art, since the fertilizer tank is mounted so as to be pivotally movable outward with the vertical axis on the front end side as a fulcrum, the fertilizer tank is moved forward as the pivot operation is performed. There is a disadvantage that it becomes difficult to replenish fertilizer from the driver's side such as the driver's seat, and since the connection position of the hose connected to the bottom of the fertilizer tank is near the rotation fulcrum, There was a possibility that the base end of the hose was twisted as the tank was rotated, and the durability of the hose was reduced.
