Description

[Detailed explanation of the idea] The present invention relates to a four-wheeled management work vehicle.

In other words, it is a four-wheeled management work vehicle that performs pest control work and other management work.It has a large capacity pest control tank and is well equipped in a safe condition, and the entire aircraft including the driver's seat and engine is well-balanced. The present invention provides a system that allows the operator to operate the aircraft safely and satisfactorily while fully observing the aircraft from the driver's seat, and to enable suitable implementation.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows an external perspective view of a management work vehicle, in which both parallel main frames 5a and 5b are extended in the front and back direction on the center side of the machine body, and both main frames 5
A lateral bumper 6 is connected to the front ends of the main frames 5a and 5b, and the middle part of the lateral front frame 7, which is the upper front part of the main frames 5a and 5b, is connected to the main frames 5.
A rear frame 9 is pivotally supported on a center pin 8 between a and 5b, and extends laterally from the rear of both main frames 5a and 5b.
a, 9b are respectively extended, and each wheel 1a, 1b,
2a, 2b are axle cases 10a which are raised upward;
The axle cases 10a, 10 of both wheels 1a, 1b are installed so as to be driven by hydraulic motors 12 inside the upper parts of the wheels 10b, 11a, 11b, respectively.
Mounting stands 13a and 13b respectively fixed to b are movably installed on both ends of the front frame 7, and axle cases 11a and 11 of both wheels 2a and 2b are mounted.
Mounting bases 14a and 14b fixedly attached to the rear frames 9a and 9b are respectively movably and fixedly attached to the rear frames 9a and 9b.

A driver's seat 3 is installed on the right side of the fuselage outside the main frame 5a and at the rear between the front and rear wheels 1a and 2a, a handle 15 is installed in front of the driver's seat 3, and a safety guard 16 is installed above. An engine E is installed on the left side of the fuselage outside the main frame 5b and between the front and rear wheels 1b and 2b, and a fuel tank 17 is installed above the front side of the engine E. A transmission case 18, which transmits power from the engine E side, is installed at a position inside the gap on the front side of the main frames 5a, 5b.

Between the driver's seat 3 and the engine E, a space C is formed above between the main frames 5c and 5b, and a space C is formed in the upper part between the main frames 5c and 5b. Frames 19a and 19b are erected, and a drive case 20 extending between both support frames 19a and 19b at the rear of the space C is mounted to the support frames 19a and 19b so as to be movable up and down with bolts 21,
It is installed so that transmission can be transmitted from the transmission case 18 to the drive case 20 via a bending transmission shaft 22 extending below the space C, and the rear part of the drive case 20 is
A PTO shaft 23 is provided protruding from the drive case 20, and a top link 24 and both lower links 25, 25 are provided.
Both lift arms 26 extend from the drive case 20 while extending a three-point linkage mechanism B consisting of
26 and both lower links 25, 25 are connected by lift links 27, 27, respectively.

A pest control tank 4 is fitted in the space C between the driver's seat 3 and the engine E, and the tank 4 is slightly higher than the driver's seat 3 and the engine E, and is above the support frames 19a and 19b. Although the tank 4 is formed to be long in the front-back direction to the side and have a large capacity, it is also possible to form an even larger capacity by bending the rear part of the tank 4 toward the side of the rear part of the fuselage to one side or both sides.

S is a known boom sprayer, which includes a tank 28,
It is equipped with a hose 29, a pump part 30, a ground shaft 31, etc., and the top link 2 is attached to the front mast 32.
4 and both lower links 25, 25 are connected and installed and configured so that transmission from the PTO shaft to the pump section 30 side via the bending transmission shaft 33 is possible.

Therefore, it is a four-wheel drive type control work vehicle that can be driven by riding on the side of the aircraft, and can perform pest control work by replenishing from the pest control tank installed in the center of the aircraft. Management work can be performed by connecting various work machines using the rear three-point link mechanism B.

In addition, as shown in Fig. 2, the three-point link mechanism B
When performing pest control work by connecting the boom sprayer S, when the tank 28 becomes empty, the tank 4 can be refilled and the work can be continued in the field.

In this way, the present invention places the driver's seat above between the front and rear wheels on one side of the aircraft, and the engine above between the front and rear wheels on the other side of the aircraft. Since the pest control tank is disposed in the space formed between the driver's seat and the engine, it is possible to install a large number of pest control tanks in a safe manner, and the driver's seat is placed on one side while the engine is mounted on the other side. By placing a pest control tank on the other side and between them, the entire aircraft can be configured in a well-balanced manner, and from the driver's seat on the side, the aircraft can be operated safely while being fully inspected, making it possible to carry out pest control work. It has the feature that it can be suitably used as a four-wheeled management work vehicle for carrying out other management work.
