JPH07157202A - Traveling pest control machine mounted with hose winder - Google Patents

Abstract

PURPOSE:To resolve the problems that the degree of freedom on the layout of members is restricted and a transmission mechanism is made complex because the driving force of a hose winder is extracted from reduction gears in the past and to provide a separate power extracting mechanism capable of synchronizing the hose winding speed with the vehicle speed. CONSTITUTION:A power extracting chain 2 is kept in contact with the driven wheel 1d of a crawler traveling device 1, and a chain is wound on the drive shaft 3 of a hose winder W from a roller shaft 2a to transmit the driving force to the hose winder W.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a traveling device equipped with a hose winding device such as a control machine.

[0002]

2. Description of the Related Art Conventionally, in a self-propelled traveling device for controlling work, which is equipped with a hose winding device, between a tank or a dynamic jet installed at a place distant from the traveling device and the hose winding device on the traveling device. It is known that a hose is connected by a hose, and the hose is unwound or wound by a winding device while traveling, and the pest control work is performed. If the hose winding speed and the vehicle speed are not synchronized, for example, if the hose winding is slow with respect to the vehicle speed, the hose loosens and interferes with the traveling device, and the hose winding speed is faster than the vehicle speed. If it is too much, the hose will be pulled and the traveling device will be slowed down, and if it is bad, there will be many problems such as damage to the hose.Therefore, synchronize the hose winding speed with the traveling device vehicle speed. Therefore, conventionally, the power of the hose winding device has been adopted from the output shaft of the speed reducer interposed between the engine and the drive wheels of the traveling device.

[0003]

However, in the conventional structure, the installation location of the speed reducer is limited when the engine is driven, and the transmission mechanism from the output shaft to the hose take-up device is adapted for running. It was complicated or complicated. Further, in the case of the motor drive, the running and the winding of the hose are performed at the same time, so the battery is drastically consumed and the capacity must be increased.

[0004]

The present invention uses the following means in order to solve the above problems. That is, in a traveling type control machine equipped with a hose winding device,
A power transmission mechanism is provided near the wheels of the traveling device, and power is transmitted from the power transmission mechanism to the hose winding device so that the vehicle speed of the traveling device and the hose winding speed are synchronized.

[0005]

The wheel may be any wheel of the traveling device. For example, the wheel arranged closest to the hose winding device may be selected, and the hose winding device may be easily connected to the wheel from the hose winding device. It can be driven.

It is a side view.

As shown in FIG. 1, the self-propelled control machine according to the present invention comprises an engine E mounted on the front part of a crawler traveling device 1 and a hose winder W mounted behind it.
The engine E is fixedly mounted on the front frame 5, and a spray pipe 6 projects vertically from the front end of the front frame 5 and stands upright in the vertical direction. Are protruded, and the chemical liquid supplied through the inside of the hose H wound by the hose winding device W is sprayed from the injection ports 7, 7 ... The hose take-up device W is covered with the device cover 4, and the hose H is arranged from the rear of the device cover 4.
It is possible to wind up and unwind.

The crawler traveling device 1 has drive wheels 1a and 1a disposed on the left and right of the front end, and an axle 1b of the drive wheel 1a is disposed between the left and right drive shafts 1a and 1a.
The drive force of the engine E is transmitted to the transmission case M, and further transmitted to the axles 1b and 1b.
The drive wheels 1a and 1a are driven, and the entire crawler traveling device 1 is driven. Further, in the crawler traveling device 1, crawlers 1e are respectively wound between the drive wheel 1a at the front end, the driven wheels 1c and 1c, and the driven wheel 1d at the rear end on the same side.

Then, between the driven wheels 1d and 1d at the rear end,
As shown in FIGS. 1 to 3, a roller shaft 2a having power take-off rollers 2.2 fixed at both ends is arranged as a power transmission mechanism, and both power take-off rollers 2.2 are brought into contact with the inner sides of the driven wheels 1d and 1d, respectively. The rollers 2 and 2 are configured to rotate in synchronization with the driven wheels 1d and 1d. A sprocket 2b is fixedly mounted on the roller shaft 2a, and a chain is wound around the sprocket 3a fixed to the drive shaft 3 of the hose retractor W from the sprocket 2b so that the drive shaft 3 is driven by the power take-off roller. The driven wheels 1d and 1d are configured to be driven in synchronism with the rotations of the driven wheels 1d and 1d. That is, the hose winding device W is synchronized with the drive speed of the crawler traveling device 1.
The drive shaft 3 is driven, and the hose winding speed is synchronized with the vehicle speed.

As described above, as a method of extracting the driving force of the hose winding device W from the driven wheels 1d of the crawler traveling device 1, as shown in FIG. 4, the gear 1f is fixedly mounted on the axle of the driven shaft 1d. The power take-off gear 8 is meshed with 1f, and the drive shaft 3 is driven from the gear shaft of the power take-out gear 8 via a sprocket.
5, or a sprocket 1g is fixedly mounted on the axle of the driven shaft 1d, the chain is wound around the power take-out sprocket 9 from the sprocket 1g, and the sprocket 3a of the drive shaft 3 is further wound. It is also conceivable to wind the chain around.

As described above, the power take-out roller 2 and the power take-out gear 8 as the power take-out members of the hose take-up device W,
Alternatively, the wheel for taking out power from the power take-out sprocket 9 is not limited to the driven wheel 1d, and the driven wheel 1c or the drive wheel 1a may be used. In addition to the crawler traveling device, a wheel type traveling device may be considered, and the driving force of the hose winding device may be taken out from the wheels of the wheel traveling device.

[0012]

Since the present invention is constructed as described above,
It has the following effects. That is, since the drive of the hose winding device mounted on the traveling device is transmitted from the wheels, the hose winding speed is synchronized with the vehicle speed in the same manner as when power is taken out from the conventional speed reducer. Since there is no interference between the hose and the traveling device, and there is no need to transmit power from the reducer as compared with the past, there is more freedom in the position of the reducer and the hose winding device. As a result, there is no need to provide a complicated transmission mechanism, and the assembly structure is simplified.
