Description

[Detailed explanation of the invention] Conventionally, the fertilizer tank in mobile agricultural machinery with a fertilizer application device was mounted at a high position above the rear wheels.
Supplying fertilizer to the fertilizer tank was extremely difficult, and the center of gravity of the aircraft was high, resulting in poor maneuverability.

Furthermore, in the case of mobile agricultural machinery such as a riding rice transplanter, when feeding seedlings from an auxiliary seedling stand to a planting device at the rear, the fertilizer tank gets in the way, making it difficult to feed the seedlings. Ta.

The purpose of this invention is to improve the above-mentioned drawbacks.The engine is mounted on the front part of the machine body equipped with a fertilizer dispensing mechanism, the top surface is covered with a bonnet, and a working machine with a fertilizer dispensing device is attached to the rear. In a mobile agricultural machine with a fertilizer applicator that is connected to the fertilizer dispensing mechanism so as to be able to be raised and lowered, a wide fertilizer tank connected to the fertilizer delivery mechanism is installed on both sides of the engine and at the fender part of the front wheels, lower than the bonnet and within the width of the fender part. It is characterized by being placed in

The embodiments shown in the drawings will be explained below.
1 has a pair of left and right front wheels 2, 2 and rear wheels 3, 3,
The aircraft is equipped with an engine covered by a bonnet 4 at the front, a pump 6 as a fertilizer delivery mechanism is installed on the side of the cockpit 5, and a planter case 7 and a plurality of planting plants are installed at the rear. A planting device 11 consisting of a rod 8..., a seedling stand 9 that reciprocates from side to side, and a float 10 is connected to be movable up and down by a top link 12 and lower links 13, 13.
An arm 14 protruding diagonally downward from the top link 12 is connected to a piston rod of a hydraulic cylinder, and a fertilizing pipe 15 of a fertilizing device is attached to the float 10 in correspondence with each planting rod 8. The discharge ports of these fertilizing pipes 15 have penetrated into the soil on the sides of the seedlings planted by the planting rods 8 during the work, and the bases of the fertilizing pipes 15... It is connected to the discharge port of the pump 6 by a hose 16.

Then, the steps 17a on both sides of the deck 17,
The portions 17a extend above the front wheels 2, 2, respectively, and the extended receiving portions 2a, 2a are formed into a rectangular frame around the periphery as shown in FIG.
Fertilizer tanks 18, 18 are provided with windows 2b, 2b facing above the front wheels 2, 2, and contain paste fertilizer.
As shown in FIGS. 4 and 5, the frame is long, wide, and low in the front and back, and the rectangular frame has a fourth
The holding plates 19, 1 may be fixed as shown in the figure, or the holding plates 19, 1 may be tilted toward the fertilizer tanks 18, 18 at the front and rear parts of the receiving parts 2a, 2a, as shown in FIG.
Since the fertilizer tank 18 has a tapered shape with a narrowed upper part in side view and front view, the fertilizer tank 18 can be pressed from the side with a holding plate 19,
It can be made detachable by pushing it between 19 and securing it with an appropriate fastener, making it possible to use it as a portable fertilizer tank.

In addition, the left and right fertilizer tanks 18, 18 are connected to the hose 2.
It is connected to the suction port of the pump 6 via pins 0 and 20.

In addition, in the drawing, 21 is the planting clutch lever, 2
2 is a hydraulic lever for raising and lowering the planting device 11;
3 is a handle, and 24, 24 is an auxiliary seedling stand.

When the above-mentioned riding rice transplanter runs while driving the planting device 11 and the pump 6, the planting rods 8... scrape off the pine seedlings in the seedling stand 9 one by one,
Planted on the rice field, pump 6 is used as fertilizer tank 18, 18
Paste fertilizer is sucked in and pumped from the planting rod 1.
Fertilizer is applied to the soil next to the seedlings planted from 5.

When supplying the spare seedlings on the auxiliary seedling stand 24 to the seedling stand 9, the operator can feed the spare seedlings to the seedling stand 9 without being obstructed by the fertilizer tanks 18, 18.

In addition, since the fertilizer tanks 18, 18 are located lower than the bonnet, fertilizer can be easily supplied without spilling, and the center of gravity of the aircraft does not become high, which prevents the stability of the aircraft from worsening. do not have.

Furthermore, since the fertilizer tank 18 is disposed within the width of the fender portion, it is possible to safely travel and rotate the aircraft without colliding with obstacles.

The present invention is directed to a mobile agricultural machine with a fertilizer application device, in which the engine is mounted on the front part of the machine body 1 equipped with a fertilizer feeding mechanism as described above, the top surface of the engine is covered with a bonnet, and a work machine with a fertilizer application device is connected to the rear so as to be able to rise and fall. The wide fertilizer tank 18 connected to the fertilizer delivery mechanism is placed on both sides of the engine and at the fender part of the front wheel 2, lower than the bonnet and within the width of the fender part.
Not only does it not obstruct the working equipment at the rear of the machine as in the past, but it also provides a good front and side field of view to determine the relationship between the crop and the machine, the relationship to the ridge, or obstacles. You can perform accurate steering maneuvers while checking the position of the vehicle.

Moreover, since the fertilizer tank 18 is located lower than the bonnet, it is significantly lower than conventional ones, making it possible to supply fertilizer extremely easily without spilling it, and without raising the center of gravity of the aircraft. The stability and maneuverability of the vehicle can be improved.
