Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for maintaining a weight balance in the front-rear direction of a working vehicle in which various agricultural working machines such as a mower are mounted on the front part of the traveling machine body.

[0002]

[Prior art]

 Conventionally, in a work vehicle in which various agricultural working machines such as a mower and a grass collector are mounted on the front part of the traveling machine body, a balance weight is mounted on the traveling machine body in order to maintain a weight balance between the front and rear when the working machine is mounted. It is attached.

[0003]

[Problems to be solved by the device]

 When the balance weight is attached to the traveling machine as in the past, the weight increase rate of the machine becomes high especially in a small work vehicle, which impairs the smoothness of traveling and working of the machine. Or work may be hindered.

The technical problem of the present invention is to eliminate the problems caused by attaching the balance weights to the traveling machine body. Therefore, the present invention is a work vehicle in which a working machine is mounted on the front part of a traveling machine body, without a balance weight being attached to the traveling machine body, capable of maintaining a weight balance in the longitudinal direction of the machine body. The purpose is to provide a device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a battery mounting portion at the rear of the traveling machine body and behind the engine room in the working vehicle in which the working machine is mounted on the front portion of the traveling machine body. This is a balance holding device in a work vehicle in which a battery is detachably mounted on a battery mounting portion.

[0006]

[Action]

 According to the present invention, since a heavy battery is mounted behind the engine room on the traveling machine body and at the rear part of the traveling machine body, the balance weight can be set with the working machine mounted on the front part of the traveling machine body. Even if it is not installed, the weight balance in the front-back direction of the aircraft is maintained. It should be noted that the battery mounted on the rear part of the traveling machine body is for supplying electric power required in the work vehicle, and is generally a heavy lead acid battery.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In the drawings, 1 is a work vehicle. Reference numeral 2 is its traveling body, 3 is a crawler traveling device, and 4 is a driver's seat. A working machine 5 is mounted on the front part of the traveling machine body 2 so as to be vertically movable. Although the working machine 5 shown in the figure is a mower, any suitable machine such as a grass harvester or a snow remover may be used depending on the type of work.

An engine room 6 is provided behind the driver's seat 4 on the traveling machine body 2, and a rear bumper 7 is provided at a rear end of the traveling machine body 2, and the engine room 6 and the rear bumper 7 are provided. A battery mounting portion 8 is formed between them. The battery 9 is detachably mounted on the battery mounting portion 8. The battery 9 serves to supply the electric power required in the work vehicle 1, and is a heavy lead-acid battery having a weight of about 20 kg.

The battery mounting portion 8 includes a mounting table 10 horizontally provided between the engine room 6 and the rear bumper 7 and a pair of left and right fixing portions 11, and the battery 9 is mounted on the mounting table 10. It is mounted and fixed to the pair of left and right fixing parts 11 by the fixing tool 12 and mounted.

The battery mounting portion 8 can be formed to be long in the left-right direction between the rear surface of the engine room 6 and the rear bumper 7 so that the mounting position of the battery 9 can be changed in the left-right direction. According to this structure, even if the work implement 5 mounted on the front part of the traveling machine body 2 has an unbalanced weight in the left-right direction, the unbalanced weight is eliminated by the mounting position of the battery 9. be able to. If the capacity (weight) of the battery 9 is selected in consideration of the weight balance with the work implement 5 within a range that can cover the amount of electric power required by the work vehicle 1, the weight balance of the machine body It is suitable for holding. Further, in the working vehicle 1 according to the present invention, since the weight balance in the front-rear direction of the machine body can be maintained without using the balance weight, it is possible to reduce the weight of the machine body and achieve smooth running and work. it can.

[0011]

[Effect of device]

 ADVANTAGE OF THE INVENTION According to this invention, in the working vehicle which equips the front part of a traveling body with a working machine, the effect of being able to maintain the weight balance in the front-back direction of a body is obtained, without attaching a balance weight to a traveling body.
