Description

[Detailed description of the invention]

[0001]

[Industrial application] This invention is a motorcycle-type riding machine with a work machine such as a cultivator or a cultivation board installed behind the machine to perform work such as tilling, weeding, cultivation, ridges, etc. in ridges. It concerns the management machine.

[0002]

2. Description of the Related Art A conventional management machine has two running wheels arranged on the left and right or one wheel in the center, and a walking type having a working machine mounted at a rear portion, and a seat provided at a center portion of four wheels and a front or rear portion. A passenger management machine provided with a working machine is well known. For example, as described in JP-A-2-276502.

[0003]

[Problem to be Solved by the Invention] When performing plowing and weeding work in furrows in upland farming, in the case of a walking-type management machine, perform a series of cultivators attached to the management machine,
In the case of a riding type management machine, a plurality of cultivators are attached to a tractor or the like to perform towing work. However, in the case of a two-wheeled walking machine, the tread is too wide to run through the furrow, and the work machine is manually lifted when turning, requiring a large amount of power, which is a heavy burden. In the case of a riding-type management machine, the aircraft cannot be turned large and small, so it is necessary to provide a large space for circulation. SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger management machine that has a small labor load and a small turning radius and is easy to handle in order to solve the above-mentioned problems.

[0004]

The object of the present invention is as described above, and has the following structure in order to achieve the object. The front wheel 1 and the rear wheel 2 are arranged in the front-rear direction.
A handle is provided above the vehicle, and a fuel tank is provided between the front wheel 1 and the rear wheel 2.
Link 9, engine E and seat 8 to support the rear wheel 2.
The arms 5.5 project rearward from the supporting frame 21
The arm 5.5 has a cultivated bottom that cuts into the soil.
A work machine such as a beta or cultivation plate is attached,
Actuator that raises and lowers the work machine between arm and arm 5.5
Data 6 is interposed .

[0005]

One end of an arm 5.5 extending rearward is attached to both ends of the rear wheel shaft 4 of the rear wheel 2.
A cultivator 3 which is a working machine S is attached to the other end of the cultivator S, and an actuator 6 is attached to one arm 5. The cultivator 3 extends the actuator 6. It moves down and moves up when it is contracted.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The purpose and structure of the present invention are as described above.
Subsequently, the embodiment shown in the attached drawings will be described. FIG.
FIG. 2 is a plan view of the motorcycle-type riding management machine of the present invention, FIG. 3 is a side view of the motorcycle-type riding management machine, and FIG. 4 is a front view of the same.

A description will be given with reference to FIGS. The front wheel 1 and the rear wheel 2 are arranged one by one on a straight line in the front-rear direction.
An engine E is arranged between the rear wheel 2 and the engine E.
A fuel tank 9 is arranged at the upper part of the vehicle, a handlebar 7 is arranged in front of the tank 9, a seat 8 is arranged at the rear, and a transmission case 22 is arranged below the seat 8 on the rear side of the engine E. It is configured as follows. The front wheel 1 is rotated left and right by operating the handle 7, and is rotatably supported by the support frame 20. The rear wheels 2 are driven by the power of the engine E, and the front ends of arms 5.5 are pivotally supported at the rear portions of both ends of a support frame 21 that supports the rear wheel shaft 4 of the rear wheels 2 so as to project rearward. A cultivator 3 serving as a work machine S is attached to the rear end of the actuator 5, and one end of an actuator 6 is attached to one arm 5, and the other end of the actuator 6 is a transmission case below the seat 8. 22.

The actuator 6 is composed of a hydraulic cylinder, and operates to expand and contract by sending hydraulic oil from a hydraulic pump attached to the transmission case 22.
When the arm extends, the arm 5 pivots downward around the rear wheel axle 4 and the cultivator 3 pivots downward to enable work. When the actuator 6 contracts, the arm 5 pivots about the rear wheel axle 4. The cultivator 3 is turned upward and turned to a non-working state. Cultivator 3
Is detachable from the arm 5, and is configured to be operable by replacing it with a cultivation plate or the like as another working machine. At the time of work, the cultivator 3 is moved downward as described above, and the work is performed.
It travels with the ascending movement.

A camera 10 is provided at the rear of the seat 8, and an arm 7a projects from the center of the handle 7 to the front, and a monitor 11 is provided on the arm 7a.
The camera 10 mainly captures the work machine S in the rear, enabling the operator to work while checking the rear with the monitor 11, and the operator does not need to turn around to check the work state and stabilize traveling. It is possible to avoid danger.

[0010] Since the vehicle speed is set relatively high, it is easy to maintain a balance, and it is possible to stably run and work like a bicycle by operating the operator. It is also possible to stabilize in the vertical direction. As shown in FIGS. 3 and 4, the engine E 'and the transmission case 22' are arranged between the front wheel 1 and the rear wheel 2, and the support shaft 26 is fixed to the frame 25 protruding above the transmission case 22 '. doing. The seat 17 is rotatably supported at the rear end of the support shaft 26, a hydraulic cylinder 15 is interposed between the lower portion of the seat 17 and the frame 25, and the vertical rod 18a of the handle 18 is supported at the front end of the support shaft 26. Then, the support frame 20 is fixed to the lower end, and the front wheel 1 is pivotally supported.
a The center of the handle 18 is pivotably supported on the upper end,
The hydraulic cylinder 16 is interposed between the steering wheel 8a and the steering wheel 18. Also, a horizontal sensor 23 and an acceleration sensor 24 are provided near the seat 17, and the horizontal sensor 23 and the acceleration sensor 24 swing with respect to the rolling of the machine. The moving angle and the swinging speed thereof are detected, and the hydraulic cylinders 15 and 16 are operated so that the seat 17 and the handle 18 are horizontal to maintain stability.

[0011]

Since the present invention has the above-described structure and embodiment, it has the following effects. First, compared to walking-type management machines,
High-speed field work is possible, and turning is easy without applying force
And less labor is required. Second, walking
Small management machines are often carried by mini cars,
It is troublesome to take down and transport, but it is a bike type
As a result, the working machine was raised by the actuator 6.
In a state, you can easily go from the barn to the field and pick up the work machine
If you remove it, you can use it as a normal motorcycle and it is versatile
You. Third, because of the simple structure, compared to tractors, etc.
It can be constructed much cheaper.
