Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a speed sprayer that has both a field crop control function and a frost damage prevention function.

[Conventional technology]

Conventionally, speed sprayers equipped with nozzles that open upward or to the left and right to suit the cultivation method of fruit trees, and boom sprayers that spray chemicals from a spray nozzle connected to a boom that extends and retracts from side to side have been proposed. .

[Problem to be solved by the invention]

By the way, with the current opening direction of the speed sprayer's jet head, it is impossible to control anything other than fruit trees and trees, and with the boom sprayer, there are problems with the methods and means for opening and closing the boom.
The complexity of the structure due to the installation of accompanying peripheral equipment, increased costs, larger size, incorrect operation, maintenance, etc.
There are many problems that need to be resolved. Furthermore, the tip of the extended boom may not be able to follow irregularities on the ground surface, leading to damage to the work equipment and damage to crops, which requires highly difficult operating techniques to avoid obstacles. The strength of the extended boom is also an issue.

[Means to solve the problem]

Here, the present invention provides a movable frame 2
, a drug tank 3, a pump 4, a blower 6,
A plurality of nozzles 9 are capable of discharging the air from the blower 6 downward and sideways in a vertical plane with respect to the direction of travel.
In the speed sprayer, a blowing head is provided with an opening 7 in which the nozzle 9 is arranged, and a wind baffle plate 10 is pivotally attached to the side end of the opening 7 so as to freely set the swinging direction of the nozzle 9. The present invention proposes a speed sprayer characterized in that an air baffle plate 11 covering the opening 7 is detachable so as to leave a gap around the opening 7.

[Effect]

Next, the present invention will be explained with reference to the accompanying drawings.

FIG. 1 is a side view of the speed sprayer of the present invention, in which a drug tank 3, a pump 4 for pumping the drug in the drug tank 3, and a pump 4 are mounted on a frame 2 provided with wheels 1. A jet head 5 that atomizes and ejects the medicine that is pumped through the jet;
A blower 6 is placed on the discharge side of the blower 6 to diffuse the atomized drug formed by the blower 6, and the blower 6 is disposed in such a manner that the air is discharged from one end (actually the rear end) of the frame 2 and is directed downward. , a blower tube 8 having a fan-shaped opening 7 is disposed, and inside the opening 7 of the blower tube 8 there is a communication pipe (not shown) communicating with the pump 4.
A plurality of nozzles 9 are provided which communicate with each other via the nozzles 9.

As shown in FIG. 2, a control plate 10 for controlling the direction of air is provided on the side edge of the opening 7 of the blast tube 8, and a control plate 10 is provided inside the opening 7 of the blast tube 8, the details of which will be described later. , a wind regulating plate 11 that partially closes this opening 7 is provided.

In order to make the frame 2 movable, for example, the frame 2 can be moved by the traction hitch bar 13 of the tractor 12.
In this case, tractor 1
By connecting the main shaft 15 on the frame 2 side to the output shaft (not shown in the figure) of the PTO of No. 2 through the universal joint 14, the main shaft 15 is rotationally driven via an appropriate transmission system. V pulley 16, belt 17, V pulley 1
8 to drive the blower 6, and the V
The pump 4 is connected to the spindle 19 of the pulley 16 with a clutch 20 interposed therebetween. A clutch switch 21 for operating the clutch 20 and a spraying knob 22 for controlling opening and closing of the nozzle 9 are attached to a support arm 23 erected on the frame 2.

In the above configuration, air is blown from the blower 6 by power transmission from the PTO output shaft of the tractor 12, and on the other hand, the clutch 20 is actuated by operating the clutch switch 21, and the jet is sent from the chemical tank 3 by the pump 4. The medicine pumped into the air blower 5 is ejected in the form of fine particles from the nozzle 9 as the spray tip 22 is operated, and is carried by the airflow from the blower 6 and dispersed toward the ground surface. During this spraying work, the wind direction is controlled by the control plate 10 according to the conditions of air blowing and chemical spraying, and the air baffle plate 11 is attached to an arbitrary position of the opening 7 of the blow tube 8 by bolts or the like. By fixing through the fastener 24, the state of the spray from the nozzle 9 can be varied in various ways by controlling the air volume, air speed, air pressure, etc. In addition, for practical purposes, this nozzle 9
Although any arrangement can be adopted, the embodiment of FIG. 3 shows two columns.

〔Effect of the invention〕

According to this invention, the following effects can be obtained. In other words, the control plate is pivotally attached to the side end of the jet opening, which prevents the mist or air from the jet opening from bouncing off the ground and rising into the sky, and also promotes its wide dispersion near the ground surface. do.

By installing a wind regulating plate around the nozzle opening to cover it while leaving a gap around the nozzle, the strength of the wind from the opening is reduced and the fog or mist from the nozzle is prevented from damaging crops on the ground. Conveys air.

By adjusting the swing angle of the control plate according to the degree of density associated with crop growth, the strength and spread of the conveying wind downward from the jet head opening can be adjusted.
