They were able to maneuver beautifully in narrow fields, such as by digging up fields with their wheels, and they had to be very careful about advancing and reversing while paying attention to their surroundings, which made the work extremely tedious.

In addition, if a special trolley is manufactured and the chemical spraying device is mounted on the trolley, the disadvantages of towing by a tractor can be overcome, but the dedicated trolley becomes more expensive.
This will lead to a significant increase in costs.

Furthermore, in both cases of towing by a tractor and mounting on a special trolley, adding a cabin and air conditioning equipment to prevent chemicals from being applied to the worker (driver) significantly increases costs.

An object of the present invention is to provide a mobile speed sprayer with a cabin that can eliminate the above-mentioned disadvantages when towed by a tractor and can suppress an increase in cost.

[Means for solving problems]

According to the speed sprayer according to the present invention, an ordinary passenger truck is used as the cart of the chemical spraying device. This ordinary passenger truck includes an auxiliary transmission connected in series to the main transmission, and a manual lever that controls the output of the driving engine. The chemical spraying device also includes a chemical tank that stores the chemical, a spray pump that sends the chemical from the chemical tank to the nozzle, a blower that blows the chemical sprayed from the nozzle outward, and a blower engine that drives the blower. It is equipped with

〔Effect of the invention〕

Ordinary passenger trucks are mass-produced, can be obtained at low prices, and are already equipped with cabins. Therefore, by using such an ordinary passenger truck as a cart on which the chemical spraying device is mounted, it is possible to eliminate the disadvantages of towing the chemical spraying device with a tractor, such as the trouble of attaching and detaching the chemical spraying device each time pest control work is performed. Costs can be significantly reduced.

By providing an auxiliary transmission, the driving torque increases and the extra horsepower of the running engine increases, so it is possible to drive in places that require a large driving force, such as when driving on soft ground. In addition, the engine rotation can be kept constant regardless of the increase or decrease of the medicine in the medicine tank or the magnitude of road surface resistance, the traveling speed can be stabilized, and the amount of medicine sprayed can be made uniform.

It is difficult to maintain a constant pressure on the accelerator pedal of a normal passenger truck in extremely uneven fields.
In this invention, since the engine output can be kept constant using the manual lever, a stable running speed can be obtained.

Throttle wire 96 is connected to throttle wire 102 and M
2O3 to link 98. The link 98 operates in relation to the amount of depression of the accelerator pedal 92, thereby controlling the opening degree of the Scotch valve. At this time, since the chain 104 only slackens due to the operation of the link 98, the throttle lever 96 does not operate in conjunction with the operation of the accelerator pedal 92. Conversely, when the throttle lever 96 is manually operated, the link 98 is pulled and activated via the throttle wire 102 and chain 104;
At this time, the accelerator wire 102 is also interlocked so that the accelerator pedal 92 can be interlocked. Although it is desirable to run the vehicle at a constant speed during the chestnut powder failure, it is extremely difficult to maintain the running speed constant by keeping the amount of depression of the accelerator pedal 92 constant during driving.

However, since the manual throttle lever 96 is held in the operated position even after the driver releases the throttle lever 96, the vehicle can be easily driven at a constant speed.

FIG. 13 shows an operation box 106 located near the driver's seat.
It shows. The operation box 106 is provided with various manual levers for operating the spray piping system of the chemical spraying device 44 described in FIG. 10.
