Abstract

PROBLEM TO BE SOLVED: To provide a controlling machine having excellent traveling stability and steering properties without losing the balance of a machine body, equipped with a fertilizer distributor. SOLUTION: A contained angle space is formed between the rear part of a driving part 2 including a fuel tank 2a of a machine body 1 and the front part of a transmission case 3 transmitted by the driving part 2 to drive machine body wheels 4. A fertilizer hopper 6 is loaded on the contained angle space so as to make the central part of its falling cylindrical part 6a into an upper position approximately corresponding to a shaft center 5 of the machine body wheels 4. The falling cylindrical part 6a is vertically equipped with a raking part of a raking rod 7 to be synchronously rotated through the transmission system of the transmission case 3 and with a distributing blade of a blade shaft 8 with laying a fall amount adjusting means of a shutter type between the raking part and the distributing blade. The base end of a discharging column 9 is connected to the fall hole end of the falling cylindrical part 6a. The discharging column 9 is installed at the front part of the transmission case 3 and the tip discharge hole of the discharging column is faced to the vicinity of the ground to give the objective controlling machine for fertilizer application.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management machine provided with a fertilizer spraying device used for topdressing work and the like.

[0002]

2. Description of the Related Art Conventionally, a mode of a management machine to which a fertilizer spraying device is attached is based on the premise that it is attached without changing a standard type of the aircraft itself, or is divided from a balance and a steering property of the aircraft. Since it is not an attached type issued, it is located far from the position of the center of gravity of the aircraft or where it affects the steering of the operator, and there remains a problem in running stability and steering characteristics.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has made intensive studies from both aspects of the body balance (mechanical engineering) and steering characteristics (ergonomics). An angled space is formed between the case and the case, and a management machine having a fertilizer spraying device attached thereto has been completed.

[0004]

In order to achieve the above object, the present invention relates to a driving unit 2 including a fuel tank 2a of an airframe 1.
And a front portion of a transmission case 3 which is transmitted from the prime mover 2 and drives the body wheels 4, forms an angle space α, and the fertilizer hopper 6 is provided with the body wheels in the angle space α. 4
Is mounted so as to be located at an upper portion substantially corresponding to the axis 5. Then, the falling portion 6a of the fertilizer hopper 6 is vertically provided with the scraping portion 7a of the scraping rod 7 and the distribution blade 8a of the blade shaft 8 which are synchronously rotated via the transmission system of the transmission case 3 vertically. Further, a drop end 6b of the drop cylinder 6a
The discharge tube 9 is connected to the base end 9b, and the discharge tube 9 is attached to the front part of the transmission case 3 so that the front end discharge port 9a is close to the ground.

[0005] In the above structure, the drop amount adjusting means 1 is provided between the scraping portion 7a facing the falling cylinder portion 6a and the distribution blade 8a.
It is a fertilizer spraying management machine provided with 0.

Further, in each of the above structures, the discharge cylinder 9
The discharge port 9a is fixed to the front part of the transmission case 3 and is disposed immediately below the discharge case 11 in the form of a distribution cut 11 having a U-shaped cross section.
It is a manure spraying management machine provided with.

[0007]

Now, a case where topping is performed on the Chinese cabbage ridge will be described. The fertilizer hopper 6 is filled with fertilizer, and the motor is started to run along the ridge. The operator can smoothly operate the spraying device because the spraying device is placed in the narrow angle space α and there is no protrusion from the body. The fertilizer hopper 6 is located in the space between the prime mover 2 and the transmission case 3 so that the center of the falling cylinder 6a is an upper portion substantially corresponding to the axis 5 of the vehicle body wheel 4. By being mounted, the position of the center of gravity of the aircraft is determined, and balanced and stable running is possible. Further, the weight at the position of the center of gravity of the airframe increases due to the weight contribution between the tare of the fertilizer hopper 6 and the stored fertilizer, and a function of suppressing a slight slip of the airframe during traveling works. The drop amount of the fertilizer can be adjusted to an appropriate amount by providing the drop amount adjusting means 10 between the scraping portion 7a facing the falling tube portion 6a and the distribution blade 8a. When the fertilizer is discharged from the discharge port 9a of the discharge tube 9, , And a distribution shoe 11 having a U-shaped cross section.

[0008]

As described above, the present invention has the advantage that the running stability and the steering performance of the airframe during the application of fertilizer are improved, and the workability is remarkably improved. Since there are almost no device parts protruding from the fuselage, the overall design of the fuselage is well organized and the design is excellent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rear portion of a prime mover 2 including a fuel tank 2a of a fuselage 1 and a body wheel 4 transmitted from the prime mover 2 are shown.
Is formed by adjusting the angle of the transmission case 3 between the front end of the transmission case 3 and the fertilizer hopper 6 in the narrow space α, and the falling cylinder The center portion of the portion 6a is mounted on an upper portion substantially coincident with the axis 5 of the vehicle body wheel 4. Then, the dropping portion 6a of the fertilizer hopper 6 and the scraping portion 7a of the scraping rod 7 and the distribution blade 8a of the blade shaft 8 which are synchronously rotated via the transmission system of the transmission case 3 are disposed between the two. It is vertically installed with a shutter type drop amount adjusting means 10 interposed. Further, a base end 9b of a discharge tube 9 made of vinyl chloride is connected to a drop end 6b of the drop tube portion 6a, and the discharge tube 9 is attached to a front portion of the transmission case 3 and a distal end thereof. Outlet 9
The vicinity of a is fixed to the front part of the transmission case 3 and a distribution machine 11 for distributing the fertilizer to the right and left in the shape of a cross section is provided immediately below the discharge case to constitute a manure spraying management machine.
