First, the loading box (1) and the drive shaft (2), the hose reel (8), the sprayer (14), the speed adjusting means (16) and the wheels (19) are the same or similar in structure and function of the known pesticide sprayer , The loading box (1) is formed to have a volume sufficient to install various mechanisms.

In addition, the drive shaft (2) is axially axially at the bottom of the front surface of the stacking box (1) to be selectively coupled with the PTO shaft of the tractor, the sprayer (14) and on the drive shaft (2) Third and fourth pulleys 3 and 4 which can be connected via first and second pulleys 15 and 10 and V-belts 5 respectively installed on the shaft 13 of the hose reel 8 respectively. And first and second clutches 6 and 7 as intermittent means for selectively transmitting the power of the tractor to them at the same time.

Therefore, when the user operates the first clutch 6, the power of the tractor transmitted through the drive shaft 2 is transmitted through the third pulley 3-V belt 5-first pulley 15. And the sprayer is operated to operate the second clutch (7), and the power of the tractor transmitted through the drive shaft (2) is transferred to the fourth pulley (4)-V belt (5)- 2 is delivered to the hose reel (8) through the pulley (10) is to rotate the hose reel to operate the winding the hose.

Of course, when the sprayer 14 or the hose reel 8 is driven by the power of the tractor, the first or second clutches 6 and 7 are separated from the drive shaft 2, respectively. 14) and the hose reel 8 are stopped.

On the other hand, the hose reel (8) which serves to wind or unwind the hose (9) having a predetermined length is installed to be rotatable through the shaft (13) on the front upper side of the loading box (1), the shaft (13) The second pulley (10) connected to the fourth pulley (4) and the belt (5) is installed at the same time, the hose alignment is the main component of the present invention through the V belt (5) unlike the conventional agricultural sprayer The fifth pulley 11 is additionally installed to transmit power of the tractor to the means 21.

In addition, the sprayer 14, which is operated by the power of the tractor and performs spraying operation of the pesticide, is fixedly installed at the other front upper side of the loading box 1, and the third pulley 3 is formed on the axis of the sprayer 14 ) And a first pulley 15 connected via the V belt 5.

In addition, the speed adjusting means 16 installed to adjust the driving speed by changing the tension of the belt 5 is built in the front portion of the stacking box 1, wherein the speed adjusting means 16 is The idle roller 17 is provided with an idle roller 17 which is rotated in contact with the outer circumferential surface of the V belt 5 provided between the second and fourth pulleys 10 and 4 in a form of selectively pressing. Tension bar 18 that can be arbitrarily changed by the user.

On the other hand, the bottom of both sides of the stacking box (1) is provided with a pair of wheels (19) capable of performing a cloud movement when the whole agricultural sprayer is suspended by the tractor, the wheel 19 is loaded in the present invention ( 1) Rotating the pesticide sprayer itself to the tractor by rotating the installation on the vertical shaft 20 protruding to the bottom of the wheel (1) when rotating the wheel 19 itself rotates at the same time as the cloud when rotating small Since it has a turning radius, it is possible to easily change the direction of tractors and sprayers even in a narrow space and to perform rapid control work.

On the other hand, the main technical configuration of the present invention is to install the hose alignment means 21 to a known agricultural sprayer so that the hose can be wound in a multi-stage alignment on the hose reel (8), the hose alignment As shown in FIG. 6, the means 21 is largely composed of a screw shaft 22, a sixth pulley 26, a guide rod 27, and a notch block 28.

At this time, the screw shaft 22 has a configuration in which the spiral groove 23 is formed on the outer circumferential surface and a pair of fixing pieces protrudingly installed on one side of the stacking box 1 through the bearing 24 The notch block 28 is alternately moved to the left and right sides through the power of the tractor transmitted through the drive shaft 2 and built in the 25.

In addition, the sixth pulley 26 is fixed to one end of the screw shaft 22 and is mutually connected to the fifth pulley 11 and the power transmission V belt 5 provided on the shaft of the hose reel 8. Since it has a connected configuration is driven when the hose reel (8) is driven to transmit the power of the tractor to the screw shaft (22).

In addition, both ends of the guide rod 27 are horizontally fixed to the fixing piece 25 at the bottom of the screw shaft 22 so that the notch block 28 is driven by the power of the tractor. It performs the function of guiding not to flow back and forth and left and right when moving along 22).

On the other hand, the notch block 28 is moved to the left and right on the screw shaft 22 and the guide rod 27 to perform a function to align the hose in multiple stages on the hose reel (8), the upper surface of the body 29 There is a pair of hose guide rollers 30 for the hose (9) to move smoothly to the hose reel (8) side is condensed and the through hole through which the screw shaft 22 is fitted on the center line in the horizontal direction of the body (29) At the same time when 31) is drilled, the inner surface is moved along the groove while being inserted into the cross-shaped spiral groove 23 on one side thereof, and when the two ends of the spiral groove 23 are reached, the respective directions are turned to notch block 28 itself. Guide and the turning projection 32 is installed to change the direction of movement of the body 29, the bottom of the body 29, the support piece 34 is formed through the through hole 33 is fitted with the guide rod 27 is projected Has a configuration.

At this time, the pair of hose guide rollers 30 are usually axially squeezed on the body 29 at a predetermined interval (that is, a gap corresponding to the thickness of the hose), but the thickness of the hose used in the pesticide sprayer Since the volume of the user or the sprayer and the spraying and non-spraying of the sprayer may be different in consideration of changes in volume due to water pressure, the guide roller 30 shaft on one side is omitted, but the spring receives elastic force from one side of the hose. It is desirable to install a little freely movable from side to side in thickness.

Referring to the operation relationship of the hose alignment means 21 having such a configuration as follows.

First, when the hose reel 8 is rotated by the rotation of the fourth pulley 4 of the drive shaft 2 and the second pulley 10 connected through the belt 5, the fifth pulley 11 is also rotated. Since the fourth pulley 4 rotates together, the sixth pulley 26 of the screw shaft 22 of the hose alignment means 21 connected through the V belt 5 also rotates, so that the screw shaft 22 also rotates. Will be rotated.

Therefore, the notch block 28 installed on the screw shaft 22 and the guide rod 27 so as to be movable from side to side is guide and turning protrusion in the through hole 31 which is perforated in the transverse direction in the body 29 thereof. A pair axially supported on the body 29 since the screw shaft 22 and the guide rod 27 on the screw shaft 22 and the guide rod 27 are gradually moved in response to the rotational speed of the screw shaft 22. Since the hose guide roller 30 also moves along the screw shaft 22 and the guide rod 27 to the left or right with a predetermined speed, the hose 9 passing between the hose guide roller 30 is called When wound on the hose reel (8) at a speed that corresponds to the rotation of the thrill (8) does not overlap with each other and is sequentially wound while moving from one side to the other side.

In addition, the notch block 28 reaches one end of the screw shaft 22 (i.e., the hose is one end of the hose reel), and the guide and pivot protrusion 32 is located at one end of the intersecting spiral groove 23. If the screw shaft 22 rotates in one direction, the notch block 28 itself starts to move in the opposite direction by the role of the guide and the turning protrusion 32 even though the screw shaft 22 rotates in one direction. .

Thus, a hose wound on the hose reel 8 passing between the hose guide rollers 30 which maintains idle rotation about an axis is wound in the opposite direction as described above on the previously wound hose.

Of course, the direction of movement of the notch block 28 continues until the guide and the turning protrusion 32 reaches the other end of the intersecting spiral groove 23 of the screw shaft 22 and then reaches the position. As described above, the hose is wound on the hose reel 8 while being automatically rotated and repeats the movement in the other opposite direction.

On the other hand, if you change the direction of the tractor to perform the control work in a specific place to change the direction of the tractor to the wheel 19 installed on the bottom of the stacking box (1) is configured to perform the rolling and rotational movement at the same time Since the radius of rotation is greatly reduced as compared to the conventional sprayer, it is possible to continuously change the direction of the tractor even in a narrow space and to continuously perform the control work.

As described above, the present invention has several advantages as compared to the conventional agricultural sprayer.

First, the hose is installed on the hose reel of the agricultural sprayer mounted on a vehicle other than the tractor, tiller or tractor trailer, so that the hose can be wound using the power from the tractor's PTO shaft. Winding takes place in a multi-stage arrangement, which prevents time loss due to the need to rearrange the hose wound on the hose reel when spraying pesticides.

Second, the hose can be easily wound and taken out, which can greatly increase the efficiency of pesticide control operations.

Third, the wheels installed on the bottom of the loading box can be rotated around the vertical axis as well as the rolling motion, so the tractor and sprayer can be easily changed even in a narrow space when the tractor sprays the pesticide sprayer and moves and changes the direction. It is possible to perform a quick control work.
