Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling planter with a fertilizer application equipped with a fertilizer applicator capable of performing good fertilizer application and seedling planting work.

[0002]

2. Description of the Related Art As a conventional technique of this type, Japanese Patent Laid-Open No. 59-59
As shown in Japanese Patent No. 125807, there is a seedling planting machine with a fertilizer application, which is equipped with a spare seedling mounting device fixed to the machine body and a fertilizer tank at a position higher than the spare seedling mounting device.

[0003]

In the prior art described above, however, since the fertilizer tank is located at a high position, it is difficult to put the fertilizer and the workability thereof is poor, and the fertilizer tank containing the fertilizer is still present. Because the car is in a high position, it has a high body weight and poor running performance.

[0004]

In order to solve the conventional problems, the present invention arranges the fertilizer tank 4 in the vicinity of the grounding position of the wheel 15 in a side view of the machine body, and above the fertilizer tank 4. A seedling planting machine with a fertilizer application is characterized in that a preliminary seedling placing device 10 is provided so as to be movable back and forth between a place where the fertilizer tank 4 is located and a place where the upper part of the fertilizer tank 4 is opened.

[0005]

Since the fertilizer tank 4 is arranged in the vicinity of the grounding position of the wheel 15 in the side view of the machine body, the center of gravity of the fertilizer tank 4 containing the fertilizer and having a relatively heavy weight can be moved by the vertical movement of the machine body. It does not change much in the front-back direction of the machine, and prevents changes in the front-back balance of the machine. Even if the amount of fertilizer in the fertilizer tank 4 fluctuates, the center of gravity of the fertilizer tank 4 is in the vicinity of the position above the ground contact position of the wheel 15, so that there is little fluctuation in the front-rear weight balance of the aircraft.

Further, since the preliminary seedling placing device 10 is disposed above the fertilizer application tank 4, the fertilizing application tank 4 protruding above the preliminary seedling placing device 10 does not become an obstacle unlike the conventional example, The seedling supply work is easy. Further, during normal work, the spare seedling placing device 10 is located above the fertilizer tank 4, its center of gravity is located near above the grounding position of the wheel 15, and due to fluctuations in the amount of placed seedlings. The front-rear weight balance of the aircraft does not change much.

On the other hand, when the fertilizer tank 4 is replenished with fertilizer, the auxiliary seedling placing device 10 is moved to a position where the upper part of the fertilizer tank 4 is opened, so that the fertilizer tank 4 at a lower position can be easily replenished with fertilizer. The workability is extremely good.

4, 4, 5, 4, and 5, and a fertilizer feeding section 5, 5, 5, 5, 5, 5, which is provided integrally below and feeds a certain amount of fertilizer, and a fertilizer fed by the feeding section 5 to the discharge section. Fertilizer transfer part 6,6,6,6,6,6 consisting of pipes to transfer and guide
From the fertilizer transfer section 6... Connected to the rear end of the fertilizer transfer section 22, and attached to the leveling floats 22, 22, 22 to dig a ditch for fertilization in a field. It is configured. Reference numeral 23 denotes an air tank which is attached to the lower side of the cockpit 9 and is provided so that air can be blown from a blower 24 driven by the engine 13 through a duct 25. Blower tube 2

The grooving device 7 is formed in a boat shape by the left and right side plates 27 and 27, and the rear end of the fertilizer transfer section 6 is fixed between the left and right side plates 27 and 27. It is connected to the fertilizer discharge pipe 28. Reference numeral 10 denotes a preliminary seedling mounting device, which corresponds to the individual seedling mounting portions for one row of the seedling tank 20 configured so that 6 rows of seedlings can be mounted side by side in the horizontal direction. A seedling placing portion 10a made of a frame configured so that six mat seedlings placed on each seedling scooping plate can be placed in parallel, and the seedling placing portion 10a extends downward from the lower front portion of the seedling placing portion 10a. The left and right front support arms 30 and 30 are rotatably pivoted to the lower ends of the left and right arms 29 and 29, respectively, and rotatably pivoted to the machine body, and to the lower side of the center of the seedling placing portion 10a.

When the lever is rotated in the two directions, the hydraulic valve 36 is switched to contract the hydraulic cylinder 32 to move the spare seedling placement device 10 to the seedling. It is provided so as to be in a supply state. still,
37 is a hydraulic pump and 38 is a relief valve.

The riding type seedling planting machine 3 constructed as described above is put in a paddy field, the seedlings are placed in the seedling tanks 20 and the fertilizers are put in the fertilizer tanks 4 ... If possible, the seedling planting device 2 is towed by the riding type traveling vehicle body 1, and the seedling planting equipment 21 is reciprocated left and right.
Plant on the soil surface prepared in 2.

Further, a fixed amount of fertilizer is gradually fed out by the fertilizer feeding section 5, ... And fed into each fertilizer transfer section 6. Then, the compressed air generated by the blower 24 is
5 into the air tank 23, and from the air tank 23 to the fertilizer transfer sections 6 through the respective air blow pipes 26,... To be fertilized in accordance with each seedling planting line.

In this way, fertilization is carried out at the same time as planting of seedlings, but during the work, if the number of seedlings placed on the seedling tank 20 becomes small, the seedling tank 20 and the spare seedling placing device 10 are as shown in FIG. When the phase in the left-right direction coincides with, the machine is stopped, the seedling supply lever 35 is operated in two directions, and the preliminary seedling mounting device 10 is inclined in the direction C until it comes into contact with the upper end of the seedling tank 20. It is possible to easily supply seedlings to the seedling tank 20 while holding the seedling scooping plate. When the supply of the seedlings is completed, the seedling supply lever 27 is operated in the opposite direction to operate the preliminary seedling loading device 10.
Is returned to the original state.

Next, when all the seedlings on the preliminary seedling mounting device 10 are supplied and the seedlings are exhausted, the rear part of the machine is attached to the ridges and stopped, and the preliminary seedling mounting device 10 is attached to the stopper 34 by the front support arm 30. The seedlings are replenished from the ridges to the preliminary seedling placing device 10 by moving the seedlings in the direction of T until they contact each other. Then, the supplementary seedling mounting device 10 that has been replenished is moved in the reverse direction until the stopper 33 contacts the front support arm 30, and the seedling planting operation is started again.

On the other hand, when the fertilizer in the fertilizer tank 4 becomes low, the preliminary seedling placing device 10 is moved in the direction T to open the fertilizer tank 4 ... and open the lid 4a of the fertilizer tank 4. A person can put a fertilizer bag on the frame body of the seedling placing portion 10a of the preliminary seedling placing device 10 and easily replenish the fertilizer into all the fertilizer tanks 4 ... In the above embodiment, the present invention is applied to the riding type seedling working machine in which the riding type vehicle body 1 is equipped with the seedling planting device 2 at the rear portion thereof. The present invention may be implemented in a riding type seedling planting machine mounted on the front part of No. 1.
