In the drawings, reference numeral 9 denotes a storage tank, 11 a power unit, H a supply hose, P a handle, SW an engine accelerator, and V an on-off valve.

Referring to the use state of the present invention as follows.

As shown in Figures 1 to 5, the handle (P) coupled to the rear end upwards, consisting of the first, second, third body (12, 13, 14) to the body portion 2, the wheel 8 is mounted The spraying rod 10 is installed, and the spray nozzle stand 40 is moved up and down by supporting rods 32, horizontal mounting rods 33 and vertical mounting rods 33 'on both side surfaces of the third body 14. In order to spray various chemical liquids by using the atomizer 1 installed to move and move up and down and vertically and horizontally and to adjust left and right widths, first, a storage tank 9 installed in the body part 2 is provided. Put a certain amount of the chemical in the) drive the power unit 11 is installed detachably.

At this time, since the electrical connection relationship of the power unit 11 is a conventional one, a detailed description and a drawing notation are omitted, and also the injection nozzle unit through the supply hose (H) and the opening / closing valve (V) from the storage tank (9). 40 is supplied with a certain amount of the chemical liquid and the power of the power unit 11, that is, the injection pressure of the chemical liquid is controlled by the engine accelerator (SW) is a known technique, so a detailed description thereof will be omitted.

As such, the chemical liquid is supplied to the injection nozzle unit 40 at a constant pressure by the power unit 11 to spray the plant, and the cultivation environment of the crop to be sprayed requires an upward adjustment of the height of the injection nozzle unit 40. If the first, when turning the handle 21 installed in the body portion 2 in one direction, as the pinion (16) connected to the rotating shaft 23 is rotated, by the rack 15 coupled to the injection nozzle stand The second body 13 of the spray table 10 in which the 40 is installed is lifted upward by a certain height, and the position of the spray nozzle 36 to which the chemical liquid is injected is adjusted upward.

In this state, when the left and right width adjustment of the injection nozzle unit 40 is required, as shown in the accompanying drawings 3d, 3e, the injection coupled to the horizontal mounting rod 33 or vertical mounting rod 33 ' In the state where the clamp 35 of the nozzle stand 40 is released so that the clamp 35 can be moved left, right, or up and down along the horizontal mounting rod 33 or the vertical mounting rod 33 '. When the injection nozzle unit 40 is moved by the left, right, or upper and lower widths to be adjusted, and the clamp 35 is tightened again, the left and right width of the injection nozzle unit 40 are adjusted and the upper and lower sides are adjusted. As the adjustment is completed, in this case, in order to adjust the left and right width adjustment and the up and down adjustment of the injection nozzle unit 40, as well as the front injection angle of the injected chemical liquid shown in Figures 3a to 3f. As described above, when the spray nozzle stand 40 is rotated and rotated in the vertical and vertical directions, Injection can be freely set the angle.

At this time, the clamp 35 is made of a combination of the screw method and the hinge method, it is possible to adjust the angle of the free injection nozzle 36 as described above.

In addition, as shown in FIG. 2, the injection nozzle unit 40 has an auxiliary clamp 35 'by which the auxiliary injection nozzle unit 40' is rotated in the vertical and horizontal directions and in the vertical and horizontal directions. Rotated and left, right width can be adjusted so that it can be adjusted freely to widen the injection range of the chemical liquid when spraying, of course, it is possible to further increase the injection efficiency, the injection nozzle unit 40 is installed The second body 13 of the spraying table 10 has a wire 5 of a cable 4 fixed to one end of the rotating rod 7 coupled to the body 2 so as to be rotatable by a hinge pin 6. Since the fixed shobar 20 is internally installed, when the second stage holding key 7 'of the rotating rod 7 is grasped and rotated in one direction to pull the wire 5, the shobar 20 is pulled downward. The third body 14 is lowered together by the fixed shaft 17 fixed to the top, the horizontal support rod 33 or the number As the injection nozzle unit 40 coupled to the mounting rod 33 'is interlocked and lowered together to adjust the height, the upper and lower heights are released, the second stage fixing key 7' of the rotating rod 7 is released and the rotating rod 7 When it is released, the injection nozzle unit 40 is returned to its original height at the initial height set above by being returned to its original position by the function (compression) given to the showbar 20.

Therefore, as the wire 5 is pulled by the two-stage fixing key 7 'of the rotating rod 7, the shovel 20 is lowered to adjust the height of the third body 14 temporarily (momentarily). This is the normal spray setting when the spray nozzle stand 40 is interrupted by obstacles (such as crutches or fixtures installed to prevent sagging of branches in the case of fruit water) in front of the sprayer 1 during spraying or progressing. The spray is not made by the angle is to prevent this.

At this time, since the support rod 32 coupled to both sides of the upper end of the third body 14 is coupled to have a constant elasticity by the tension body 37, a relatively small load (when the branch of the fruit is jammed to block the progression). Is absorbed by the tension force applied, absorbs the load and returns to its original position.

On the other hand, as shown in Figs. 6 to 7B, the injection nozzle stage 40 having a plurality of injection nozzles 36 is vertically and horizontally moved up and down by the clamp 35 and vertically and horizontally. As it is coupled to a vertical mounting rod 33 'which is erected and installed in the body portion 2 so as to be rotated and rotated in a directional direction, the vertical positioning rod 33' can be started using the clamp 35. As a user can freely adjust the height of the nozzle 40 to the desired position.

At this time, the body portion (2) in which the injection nozzle unit 40 is installed can be easily installed and used in a two-wheeled vehicle or a three-wheeled, four-wheeled vehicle as well as a one-wheeled vehicle consisting of one wheel (8) Of course.

In this way, in spraying the chemical liquid to the crop, the power sprayer can be used easily and easily even in a relatively small space (such as a rice field, a garden or a vinyl house), and the angle and position of the spray nozzle 36 can be freely set freely. Can be set to remove the blind spots that are not sprayed with chemicals can increase the spraying efficiency.

By using a power sprayer capable of adjusting the height and width of the spray nozzle according to the present invention, spraying can be performed quickly and safely regardless of the height and width of the crop, even in a narrow space, and the spray nozzle It is possible to adjust the height of the stand and the left and right width as well as the two-stage structure for instantaneous adjustment, so that the user can freely set the spraying angle and position when spraying the chemical liquid freely to maximize the spraying efficiency. It is easy to use, easy to handle, and low in price by simplifying the structure of the sprayer, so it is possible to increase farm income by reducing the cost of purchase.
