Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation structure of a main clutch of a self-propelled control machine for carrying out control work of fruit trees by mounting a spraying work machine on a traveling vehicle.

[0002]

2. Description of the Related Art Speed sprayers have been conventionally known as self-propelled control machines. In the speed sprayer, an engine is arranged on the side of a driver's seat, and the driving force of the engine drives a traveling device, a spray device and the like via a mission case.

[0003]

With the conventional structure, the power is transmitted from the output shaft of the engine to the mission case via the main clutch, and the power is transmitted from the mission case to the traveling device. Power is transmitted to the rear, and the transmission path becomes longer in the front-back direction. Further, the main clutch is fixed to the chassis via a dedicated fixing member, which increases the number of assembly steps and the number of parts.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, a driver's seat is provided on the front part of the chassis of the traveling part, a mission case is arranged on the central part of the chassis, a drug tank is provided on it, and an engine and a spray part are placed on the rear part of the chassis. The main clutch is suspended below the engine stand on which it is placed, and power is transmitted from the engine to the mission case via the main clutch.

[0005]

Next, the operation will be explained. The engine base is fixed on the rear part of the chassis, the engine E is mounted on the engine base, and the clutch case of the main clutch is suspended under the engine base to output the output of the engine E. The power is transmitted from the shaft to the main clutch via the pulley and the belt, and the power is transmitted from the main clutch to the mission case via the universal joint.

EXAMPLES Next, examples will be described. 1 is an overall side view of the nozzle rocking type control machine, FIG. 2 is the same plan view, FIG. 3 is the same rear view, FIG. 4 is a side view of the running portion of the nozzle rocking type control machine, and FIG. It is a side surface sectional view of a part.

The self-propelled control machine comprises a traveling section A and a spraying work machine B mounted on the traveling section A. First, the traveling unit A will be described with reference to FIGS. There are crawler type and wheel type traveling means, but in this embodiment,
A wheel type traveling device 33 is adopted.

As shown in FIG. 4, in the traveling section A of the self-propelled control machine of this embodiment, as shown in FIG. 4, the chassis 32 includes a front frame 32a, a connecting frame 32b, a seat frame 32c, a connecting frame 32d and a central frame. 32e, a connecting frame 32f, and a rear frame 32g are integrally connected and fixed, and a step 34 is formed on the front frame 32a.
And the seat frame 3 at the rear of the front frame 32a.
A seat 35 is disposed above the center of the step 2c, an operation column 36 is provided upright at the center of the front end of the step 34, and a handle 36a is provided above the operation column 36. Further, a spray operation panel 39 is arranged on the left side of the seat 35 so that the start / stop of spraying and the discharge amount can be adjusted.

A front axle case 42F is attached to a lower portion of the seat frame 32c, the seat frame 32c is positioned in an inverted U shape by the connecting frames 32b and 32d, and the rear frame 32g is similarly connected. 32f is located above and is configured to lower the vehicle height H. Then, the front bracket 44F and the rear bracket 4 are provided on the lower portion of the rear frame 32g.
4R is vertically installed, and the front and rear of the left and right center of the rear axle case 42R is pivotally supported on the lower portions of the front bracket 44F and the rear bracket 44R, and the rear axle case 42R is pivotally supported in the left and right directions as shown in FIG. are doing.

A mission case M is placed on the central frame 32e, and a drug tank 38 is further provided above.
A canopy 37 that can be opened and closed protrudes forward from the medicine tank 38, and a lid 30 is provided on the upper central surface of the medicine tank 38 for filling the medicine. Then, the engine E, the power sprayer D, the hydraulic pump P, and the spraying portion N are placed on the rear frame 32g and covered by the engine cover 41 and the cover 31, so that the hydraulic pump P can expand and contract the steering cylinder and the like. I have to. In the present embodiment, the cover 31 is rotatable laterally together with the base of the nozzle 1 so as to improve the maintainability of the nozzle 1. Further, the engine E drives the wheel type traveling device 33 via the mission case M, and at the same time, it also drives the power sprayer D to suck the liquid medicine from the medicine tank 38 by the power sprayer D to spray the spraying portion. It is configured to spray from N swingable nozzles 1.1.

As shown in FIG. 5, the power from the engine E is supplied from the output pulley 26 fixed to the output shaft 25 of the engine E via a belt to a hydraulic pump P and a power sprayer D.
And the power is transmitted to the main clutch pulley 50. The main clutch pulley 50 includes friction plates 51, 51.
And the friction plates 51 and 52 on the clutch shaft 49 forming the main clutch 40.
・ 51 are arranged alternately so that they can be connected and disconnected by operating from the driver's seat. The clutch shaft 49 is rotatably supported by the clutch case 47 via bearings,
The clutch case 47 is suspended from the lower portion of the engine base 45 on which the engine E is mounted. Both sides of the engine base 45 are fixed on the rear frame 32g via vibration-proof rubber.

The front end of the clutch shaft 49 of the main clutch 40 is transmitted to the input shaft 46 of the mission case M via the universal joint 53, the gear is changed in the transmission case M, and the front and rear surfaces of the mission case M are projected. The output shaft is input to the front axle case 42F and the rear axle case 42R via a universal joint to drive the four front wheels 33a and 33a and the rear wheels 33b and 33b.

[0013]

Since the present invention is constructed as described above, it has the following effects. That is, since the clutch case is hung below the engine base, the engine and the main clutch can be arranged close to each other, the member connecting them can be shortened, and the loss can be reduced to a compact structure. Moreover, since both are fixed to the engine base, the number of parts of the fixing member can be reduced.
