Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for enabling a riding unit to be mounted on a front part of a management machine or a cultivator to be used as a riding management machine, or to be removed to be used as a walking management machine.

[0002]

2. Description of the Related Art Conventional walking-type management machines and cultivators are convenient for managing small-scale fields, but when the field is far from the field or when the work is performed for a long time, the worker is required to take care of the workers. Fatigue is inevitable. In particular, the number of farmers is decreasing year by year, and the elderly and women are increasingly working. When such elderly people and women work, it is physically difficult to work while walking for a long time.

[0003] In view of such a situation, in recent years, the elderly and women can easily perform management work, the cost is lower than that of a tractor, and a four-wheeled passenger is required to be able to perform management work in a small field or upland field. Management machines are being used. As a technique of the four-wheel riding management machine, for example, a technique disclosed in Japanese Patent Application Laid-Open No. 7-289017 is known. Also,
Conventionally, a technique is also known in which a seat is arranged at the rear of a conventional cultivator or management machine to make a riding cultivator, or a handle is attached to a tail wheel so that the tail wheel advances in the opposite direction (rearward). For example, Japanese Patent Publication No. 40-48 and Japanese Patent Publication No. 40-63
It is like the technology of No. 69.

[0004]

However, in the case of a four-wheel riding management machine, the turning radius is larger than that of a walking management machine, and particularly, work in a house can hardly be performed, and a tread or a wheel base has a tractor. Because it is narrower than it is, there is a great sense of fear when tilting over ridges and ridges. Moreover, the price was higher than that of the walking management machine.

When the walking type cultivator is a riding type, the steering wheel and the seat are fixed to the same frame. Therefore, when turning, the side clutch lever must be gripped or descended to change the direction. Therefore, when the turning radius is large, the vehicle can be turned by operating the side clutch lever. However, it is necessary to step down and operate when turning sharply or when turning, so that the operability is poor.

In the case where the tail wheel is mounted on the tail wheel so as to travel rearward, when the rotary wheel is plowed, a wheel mark remains, so that a working machine must be mounted on the front end of the engine frame. It is necessary to change the power transmission path of the vehicle, and the type of work is limited. The present invention has been made in view of the above circumstances, and aims to provide a management machine that can easily switch between riding traveling and walking traveling.

[0007]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. The riding unit according to claim 1, wherein the riding unit is mounted on a front part of the walking management machine so as to be able to sit and steer, and the mounting unit, the seat, the handle, and the handle are mounted on the front hitch of the management machine. It is composed of steering wheels that can be turned left and right by turning.

According to a second aspect of the present invention, an elevating mechanism is disposed at the mounting portion.

A main clutch lever 24, an accelerator lever 27, a side clutch The levers 29L and 29R are arranged. The handle base 25 is configured to be rotatable back and forth around a vertical axis with respect to the transmission case 5, so that the handle 26 can be turned forward in a horizontal direction as shown in FIG. I have to. Reference numeral 49 denotes a shift lever.

Next, the structure of the riding unit 1 of the present invention will be described with reference to FIGS. The riding unit 1 includes a front hitch 3 provided at a front end of the engine frame 3.
1 is mounted via an elevating mechanism 46, and the elevating mechanism 46 is attached by inserting a pin 40 into a bracket 30 serving as an attachment part to be attached to the front hitch 31. The front hitch 31 functions as a bumper, and can be equipped with a working machine, a front weight, and the like. A rail support portion 30a and a screw rod insertion hole 30b are formed at a front portion of the bracket 30,
The rail support portion 30a guides and fits the guide rails 32 so as to be slidable up and down, and a screw rod 33 is screwed into the screw rod insertion hole 30b.

The upper ends of the guide rails 32 are fixed to the lower surface of the main frame 34, and the upper part of the elevating screw rod 33 is rotatably supported by a pivot support 47 fixed to the main frame 34, and the elevating screw is Elevating handle 3 at the upper end of rod 33
5 is fixed, the lifting screw 35 is rotated by rotating the lifting handle 35, the bracket 30 is raised and lowered, and the interval between the main frame 34 and the front hitch 31 is changed, and the forward / reverse rotation is performed. The rotary 7 is adapted to be able to adjust the non-working state in FIG. 1, the working state in FIG. 4, and the tillage depth. In this embodiment, the guide rails 32 are fitted to the rail support portions 30a on both sides of the bracket 30. However, one or three or more guide rails 32 may be provided. Guide rods can be arranged on both sides, and a rack or a cylinder can be used instead of the elevating screw rod 33. The configuration of the elevating mechanism 46 is not limited.

The main frame 34 is formed in an L shape in side view, and a seat 44 is provided on a rear end of the main frame 34.
So that the seat 44 is located above the engine 4 when the riding unit 1 is mounted on the cultivator. The front portion of the main frame 34 is formed in a flat plate shape to form a step 34a, a handle column 36 is erected on the center of the step 34a, and a handle shaft 37 is rotatably supported on the handle column 36. A handle 39 is fixed to the upper end of 37. The handle 39 may be a bar type or a wheel type. The lower end of the handle shaft 37 projects downward from the main frame 34 and is fixed to the upper end of a wheel support 42, and the steering wheel 41 is rotatably supported on the wheel support 42, and the handle 39 is rotated. Thus, the steering wheel 41 can be rotated left and right. However, although the wheel support 42 is configured to support one wheel, it may be configured to support two wheels. In this case, the positions of the two wheels are made to coincide with the positions of the running wheels 9L and 9R and the left and right positions. Further, since the wheel support 42, the seat 42, the handle 39, and the elevating mechanism 46 can be disassembled, they can be stored compactly when the passenger unit 1 is removed.

A main clutch lever 43 is disposed on the handle column 36, and the main clutch lever 43 is connected to the belt tension clutch via a wire. Further, a side clutch pedal 45 is arranged on the step 34a, and the side clutch pedal 45 is connected to the side clutch lever 29 or the side clutch arm of the transmission case 5 via a wire 47.

However, the side clutch pedal 45 is eliminated, and as shown in FIG. 4, the handle 26 is turned forward, and the driver turns on the seat 41 between the left and right handles 26, 26 and turns sharply. At times, the side clutch levers 29L and 29R can be gripped to make a sharp turn with the rotation of the handle 39. In addition, an accelerator lever is provided on the handle 39, and the accelerator lever 2 is provided.
7 may be configured to be connected via a wire, or a brake pedal may be provided on the step 34a, and a brake may be configured in the transmission case 5 to be connected via a wire.

With this configuration, the riding unit 1 can be attached to and detached from the front hitch 31 simply by inserting and removing the pins 40, and can be easily and quickly removed. When the passenger unit 1 is mounted, the vehicle can travel on three wheels, ie, the steering wheel 41 and the traveling wheels 9L and 9R. The seat 44 is located between the three wheels, and the worker sits down, and the weight is stabilized. Good balance. And FIG.
As shown in (2), when the lifting handle 35 is rotated to narrow the interval between the mounting bracket 30 and the main frame 34 and raise the engine 4 side, the rotary tilling device is lowered and tilling work can be performed. Conversely, when the distance between the mounting bracket 30 and the main frame 34 is increased, the engine 4 is lowered, and the rotary tilling device is lifted up, so that the rotary tilling device is in a non-tiling state in which it runs or rotates.

In this way, when traveling on the road, the riding unit 1 is attached, and the worker can easily move to the field or work while sitting on the seat 44 while sitting. Further, the steering can be performed by operating the handle 39, and when the vehicle turns sharply, the driver can quickly turn by depressing the side clutch pedal 45. At the time of work, even in the case of a relatively hard field, there is no sudden start because of the forward / reverse rotary 7. Further, when the field is soft, the steering wheel 41 is buried and cannot run, and since the uncultivated area becomes large in a narrow field, the rider unit 1 is removed, and work is performed while walking from behind. As described above, the work can be performed according to the field conditions of the walking type and the riding type.

[0022]

As described above, the present invention has the following advantages. First, as in claim 1,
