Description

[Detailed Description of the Invention] The present invention relates to a self-propelled speed sprayer device that atomizes and sprays disinfectant while moving through an orchard.

The speed sprayer uses tires or crawlers for self-propulsion.
The vehicle has a traveling device, on which a liquid tank, engine, fan, etc. are mounted.

These arrangements inevitably increase the height of the aircraft, making it impossible to create a driver's seat to cover the driver.

However, in order to spray atomized disinfectant over a wide area,
Depending on the direction of the wind, drivers may be covered in fog.

For this reason, the present invention provides a windshield that covers only the head of the driver sitting on the low-floor seat, and integrates the windshield with the door for getting on and off, making it light enough to be opened when getting on and off. It is.

In addition, the windshield is made of transparent resin, etc., but since fog quickly clouds the surface and reduces visibility, it is necessary to install a wiper that rotates at least in the front and rear of the windshield, and preferably around the entire circumference. This is an attempt to clear the clouds and make driving safer.

Next, the configuration of the present invention will be explained based on the configuration of the embodiment shown in the attached drawings.

Figure 1 is a left side view of the speed sprayer of the present invention.

Figure 2 is also a right side view. FIG. 3 is a right side view of FIG. 2 with the windshield opened.

Since the speed sprayer performs disinfection work within the orchard, it is required to have a vehicle height lower than the lower branches of the fruit trees.

A chassis 10 is suspended over a front wheel 11 that is a steering wheel and a rear wheel 12 that is a driving wheel, and a driving device such as a steering handle 4 is placed at the front of the chassis 10, and a liquid tank is placed at the rear of the chassis 10. It is set up as follows.

A seat 2 is provided at the center of the front part of the liquid tank 1 by forming a concave part during blow molding of the liquid tank.

This has the double advantage that the liquid tank 1 can have a large capacity and the seat 2 does not have to be made separately.

A windshield 6 made of a transparent plate is provided from the front part of the driver's seat to the upper surface of the liquid tank 1, and a wiper 5 is brought into contact with the top of the hemispherical part 6a of the windshield 6 and rotated.

Further, a door 6b for getting on and off is integrally formed on the side surface of the windshield 6 so that it can be opened at the same time.

5C is the electric motor of wiper 5.

The speed sprayer uses a fan 9 and a nozzle 8 installed at the rear of the liquid tank 1 to spray disinfectant into a mist, and it is required to spray as much mist as possible, as high as possible, and over a wide area. The more the requirements are met, the higher the chance that drivers will be exposed to disinfectant.

In order to solve this problem, a closed type windshield 6 is provided from the driver's seat to the upper part of the liquid tank 1.

In order to ventilate the inside of the windshield, the driver's cab and the fan are connected with a pipe to perform air conditioning and ventilation using the suction air of the fan 9.

There is an engine room 7 immediately behind the liquid tank 1, and an engine 13, a transmission transmission 14, and a power sprayer 15 are housed in the engine room 7.

This arrangement is shown in FIG.

The disinfectant liquid pumped by the power sprayer 15 is sprayed in the form of mist from the sprayer 8.

The nozzles are composed of multiple nozzles and are arranged along the circumference of the fan 9.

The mist of the sprayed disinfectant floats up on the airflow of the fan, and at this time is divided into finer mist by the strong wind of the fan 9.

When adhering to the leaves of fruit trees, the finer the particles of mist, the better the disinfection effect will be without damaging the fruit trees.In order to spread the mist throughout the fruit tree without any gaps and evenly, It is required that the mist flow be high and spread over a wide area.

When the fan 9 sucks air from behind and blows the air toward the nozzle 8 side, the direction of the wind is changed to spread outward at the nozzle.

The mist is spread over a semicircular surface perpendicular to the speed sprayer's direction of travel.

A slight difference in wind direction can cause this stream of mist to blow toward the driver.

The windshield 6 mainly consists of a hemispherical portion 6a on the ceiling, and has a door 6b for getting on and off on the side.

Further, the front part of the speed sprayer is provided with a bonnet as in the conventional manner.

The windshield 6 is made of a transparent body as a whole, and can be opened by integrally rotating forward.

The driver's seat 2 is made by molding the liquid tank 1, and is provided in the center to improve visibility, with parts of the liquid tank 1 protruding from the left and right sides of the seat.

The wiper provided at the top of the windshield 6 rotates around the entire circumference of the hemispherical portion 6a, and rotates 360 degrees around the driver 3, effectively improving visibility.

The driver's seat 2 is of a low-floor type and is configured so that the driver's legs can be stretched forward and the seat posture can be as low as possible.

This makes it possible to use the speed sprayer even in orchards where grapes and the like are grown on low trellises.

FIG. 4 is a bottom view of the speed sprayer of the present invention.

11 is a front wheel as a steering wheel, and 12 is a rear wheel as a driving wheel.

In the engine room 7, an engine 13 is placed on the right side, and a transmission transmission 14 is placed in the center.

Further, a power sprayer 15 is disposed on the left side, and power is transmitted from the engine 13 to force-feed the disinfectant.

FIG. 5 is a plan view of the liquid tank 1.

FIG. 6 is also a front view of the liquid tank.

The liquid tank is made by blow molding using resin, and the seat 2 is also molded at the same time as the molding.

The armrest of seat 2 was also molded at the same time. In the past, the liquid tank and seat were made separately and placed one after the other, which resulted in a longer fuselage and a smaller capacity for the liquid tank, which was resolved by making effective use of space.

The rear part of the hemispherical portion 6a of the windshield 6 is placed on the upper surface of the liquid tank 1.

FIG. 7 is a plan view showing another embodiment of the liquid tank 1.

FIG. 8 is a front view of another embodiment of the liquid tank 1.

In this embodiment, the liquid tank 1 has a concave front surface and protrudes from both sides, so that the liquid tank 1 surrounds the seat.

This invention was specifically intended to lower the seat floor, making it possible to place the driver in an even lower position.

As described above, the present invention has the door 6b for getting on and off on the side of the driver's seat 2 integrally provided on the side, and the windshield 6a extending from above the driver's seat 2 to above the liquid tank 1 and forming a hemispherical part 6a. The hemispherical portion 6 of the windshield is
aThe wiper, which rotates all around, is installed so that it rotates centered above the head of the driver 3, so by integrating the door for getting on and off and the windshield, the number of parts can be reduced, and the driver can also easily get on and off the vehicle. In this case, the windshield could be opened by opening only the passenger door, making it easier to get on and off the vehicle.

In addition, since the top of the windshield is made into a hemispherical part, a wiper that rotates around the entire circumference can be installed, and it is possible to wipe off chemical liquid from the entire circumference of the driver's head.
This allows you to always have a good field of view.
