Description

[Detailed Description of the Invention] The present invention relates to an air curtain that protects the driver's seat of a self-propelled power sprayer.

A self-propelled power sprayer is a device that travels within an orchard and uses a blower installed at the rear to blow up a spray stream over a wide area and at a high height, disinfecting a wide area of fruit trees at once.

Therefore, since the spray is blown up over a wide area without restriction, depending on the wind direction or the presence of obstacles, the harmful spray may flow directly towards the driver in the driver's seat.

In order to prevent this, it would be possible to install a windshield in the driver's seat that is more secure than a transparent panel, but this would lead to an increase in the height of the aircraft, making it difficult for the orchard to travel.

Taking these points into consideration, the aircraft does not have to raise the height of the aircraft, but rather uses air generated by a blower to blow out an air curtain around the driver's seat to protect against the spray of disinfectant. be.

The air for this air curtain is obtained by attaching an air collection port to the air guide wall, and is guided to the area around the driver's seat via a duct.

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 an overall view of the self-propelled power sprayer of the present invention.

FIG. 2 is a partial rear view of the self-propelled power sprayer.

FIG. 3 is an enlarged view of the front driver's seat area.

4 and 5 are a side sectional view and a rear view of the air collection port 3. FIG.

A driver's seat 13 where the driver 1 sits is located on the right side of the control section 8 in the direction of movement, and an engine for driving the vehicle and the like are arranged on the left side of the control section 8.

A tank γ is placed in the center, and a disinfectant solution is stored in the tank γ.

A spray drive unit 9 at the rear of the tank 7 has a built-in engine for driving the spray machine and the blower 4.

Behind the spray drive unit 9 is an outlet section for a spray stream in which nozzles 16 are arranged on the circumference, and the blower 4 is placed at the rear of the outlet section.

The blower 4 is an axial type blower that sucks air from behind and blows it out to the front, and is protected by a rear guard 5 to prevent collisions with obstacles and to ensure safety.

The rear guard 5 is attached to the airframe, and also serves to protect the blower from sucking sand and pebbles directly below it.

The rear surface of the spray drive unit 9 is directly hit by the wind blown out by the blower 4, and the wind is diffused in a semicircular plane perpendicular to the direction of travel.

At this time, a wind guide wall 10 having a truncated conical shape and a curved surface is attached to gradually change the wind direction so that the wind from the blower 4 does not directly collide with each other and excessively reduce the wind speed.

The disinfectant solution atomized by the nozzle 16 is blown away by the diffused wind whose direction is changed by the air guide plate.

6 is a running wheel. The air collection port 3 is attached to this air guide wall 10 along the wall of the air guide wall 10.

As shown in FIGS. 4 and 5, the inlet 3a of the air collection port 30 has a semicircular shape along the air guide wall, and the arc 3b portion is in close contact with the air guide wall.

Similarly, the curved surface 3C is in close contact with the outer curved surface of the air guide wall 10.

Then, it is constricted on the spray drive part to form a duct 2, and is sent to the control part 8 through the upper part of the tank.

In FIG. 3, the duct 2 is connected to the exhaust port around the pilot seat 130 of the pilot section 8.

The air exhaust port is composed of an air exhaust port 12 provided on the front side of the tank 7 that blows air out to the back of the operator 1, and an air exhaust port 11 provided forward on the cockpit seat that blows air out to the side surface of the operator 1.

The air exhaust port 12 provided at the front of the tank extends to the footwell below the driver's seat 13, and only the front side of the air curtain is opened and the rear side is protected.

The air curtain blows out in a slightly forward direction for better protection, so the outlet is sloped forward.

As described above, in this invention, the air collection port 3 is attached to the air guide wall 10, and the air exhaust port 12 is provided around the rear of the driver's seat 13 to form an air curtain, so that the speed of the wind flowing along the air guide wall is reduced. It was possible to create an air curtain by drawing in a large amount of wind, and because the duct ran through the top of the tank, the air could be sent over the shortest distance, making it possible to create a strong air curtain.
