Description

[Detailed explanation of the invention] This invention is a speed sprayer device among agricultural machinery that disinfects fruit trees by spraying a mist of disinfectant liquid high into the air while driving under the branches of an orchard. , it is possible to attach a working machine other than a pest control device.

The speed sprayer performs pest control work while traveling under the fruit trees in the orchard, which are shaped like low fences, so the vehicle height is low so that it can run without touching the branches. This invention utilizes the low floor and rideability of this speed sprayer device to prevent agricultural tractors from passing through orchards.
Weeding, underbrushing, and intertilling were carried out on foot using a small management machine or Taylor, which took a lot of time and effort, but I decided to do it with a speed sprayer while still riding on the machine, in the same way as with an agricultural tractor. It is something to do.

In order to achieve this purpose, in the present invention, a spray transmission case is provided between the engine for the spray device and the blower, and the blower drive shaft and PTO shaft are taken out from the spray transmission case, and each is controlled by a clutch device. The shafts can be driven independently.

As a result, the PTO shaft protrudes toward the rear of the blower of the speed sprayer device, and the PTO shaft drives the rotary mower device or rotary tilling device attached to the three-point link type work equipment mounting device behind the blower. It can perform the same work as an agricultural tractor in an orchard.

The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

Fig. 1 is a plan view of a speed sprayer with a rotary tiller installed behind the blower; Fig. 2 is a side view of the speed sprayer; Side view, Figure 4 is when the blower is being driven.
Figure 5 shows a state in which the PTO shaft is stopped and the blower is stopped by driving the PTO shaft.

The speed sprayer device is installed on the front bonnet 1.
A traveling engine 6 is disposed inside the vehicle, a clutch housing 7 is fixed to the rear surface of the traveling engine 6, and a traveling transmission case 8 is fixed to the rear surface of the clutch housing 7. Power is transmitted from the traveling transmission case 8 to the rear wheel differential case 9 via a power transmission shaft, thereby driving the speed sprayer device. 20, 20 are front wheels, and 10, 10 are rear wheels.

A steering handle and a seat are provided in a cutout on the right side of the front bonnet 1. Further, a pest control liquid tank 2 is disposed horizontally next to the front bonnet 1, and a spray device engine 12 and a spray transmission case 11 are disposed in the rear bonnet 3 at the rear of the pest control liquid tank 2. Spray transmission case 1
The blower 5 is driven by a blower drive shaft 22 protruding from above the blower 1, and the control liquid sprayed in the form of mist from the spray nozzle 4 is sprayed up in a semicircular shape by pressure air.
A work equipment support stand 17 is erected at the rear end of the chassis 19 that supports the blower 5, and a top link 15 and lower links 16, 16 are provided on the work equipment support stand 17.
A rotary tillage device 13 is attached. A lift cylinder is interposed from the work equipment support stand 17 to the lift arm 14, and the rotary tilling device 13
etc., are moved up and down.

As shown in FIGS. 3, 4, and 5, a PTO shaft 18 for driving a working machine such as a rotary tiller is protruded from the spraying mission case 11 through the lower part. A power transmission shaft 30 is connected to the rear end of this PTO shaft 18 via a universal joint.
are connected in series to drive the rotary tilling device 13.

Power is transmitted from the spray device engine 12 to the spray transmission case 11 through an input shaft 23, and the input shaft 23 transmits power to the blower drive shaft 22 via a hydraulic clutch device 24. 21 is a blower blade.

In addition, power is constantly transmitted from the sprocket 26 on the input shaft 23 to the sprocket 28 on the lower shaft via a chain, etc., and the rotation of the sprocket 28 is connected and disconnected by the hydraulic clutch device 25, while the PTO shaft 18 is being transmitted to.

The blower drive shaft 22 and the PTO shaft 18 can be driven at the same time to perform intercultivation and weeding while performing pest control work.Of course, it is also possible to drive only the blower drive shaft 22 or the PTO shaft 18. It is possible and
These changes are made by a hydraulic directional control valve 29 on the spray transmission case 11.

As described above, the present invention is a speed sprayer device in which two engines, the traveling engine 6 and the sprayer engine 12, are arranged, and the sprayer transmission case 11 is provided between the sprayer engine 12 and the blower 5, and the sprayer is Take out the blower drive shaft 22 and PTO shaft 18 from the transmission case 11,
The clutch device allows each shaft to be driven independently, so even if the PTO shaft cannot be removed from the driving engine due to the disinfectant tank, it can be removed from the sprayer engine.
By taking it out from the spray equipment engine, the PTO shaft can be shortened, and when using the work machine with the blower stopped, the full horsepower of the spray equipment engine can be used, making it possible to use the full horsepower of the spray equipment engine. Rotary tillage equipment can be used, and if you want to perform pest control work at the same time, you can work more effectively in the orchard by using a rotary mower or other working machine that requires less horsepower. be.
