[0004] Conventionally, when storing a scatter tube of a powder-granule dispersing machine, an operator moves to a joint portion of the scatter tube and manually bends the joint portion. Contains scatter tubes. Also, when expanding the scatter tube, the operator moves to the joint portion,
The joint portion is manually expanded to make the spray tube sprayable. For this reason, each time the scatter tube is stored or expanded, the driving operation is interrupted, and the workability is deteriorated and the bending operation is complicated. [0005] Therefore, when storing or expanding the spraying tube of the powder and granule spraying machine, the operator must be away from the driver's seat to eliminate the manual operation at the joint portion and to improve the workability. Technical challenges arise,
An object of the present invention is to solve this problem. SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object, and stores powder and granules in a hopper (13) mounted on a vehicle body (12). (12)
A sprinkling pipe (17) is attached in the left and right direction, and a joint part (22) is provided in a part of the sprinkling pipe (17) so that the sprinkling pipe (17) can be bent freely. In the powder / granule sprayer which is adapted to spray the spray from the spray pipe (17) to the field, the joint part (22) of the spray pipe (17) has a flexible pipe (23) and the pipe (23) and an annular body (27) surrounding the annular body (2).
7) is connected to a first arm (2) rotatably in the horizontal direction.

An actuator (30) is connected to the first arm (24), and one end of a wire (35) is locked at a position outside the joint portion (22) of the scatter tube (17).
The present invention provides a powder-spraying machine characterized in that the wire (35) is connected to a manual lever (41) via a pulley (37) or the like. [0007] A flexible tube is provided at the joint portion of the spraying tube. The tube has a first arm which is rotatable in a horizontal direction and a second arm which is rotatable in a vertical direction. When the actuator is driven , the first arm is bent horizontally and inwardly of the vehicle body. At that time, the pipe body is bent in the horizontal direction, and the scatter pipe is bent at substantially the entire width position of the vehicle body. Therefore, the tip of the spray tube is rotated forward and stored horizontally in the left and right sides of the vehicle body. [0008] Then, the actuator in such a state
When driven in the opposite direction , the first arm rotates horizontally and outwardly of the vehicle body and extends. Then, while the pipe body returns from the bent state to the extended state, the distal end of the scatter pipe rotates backward, the bent portion of the scatter pipe expands, and the scatter pipe becomes a straight state. On the other hand, when the wire is pulled by the manual lever, the tip of the spray tube is pulled upward, and the second arm rotates in the vertical direction. Therefore, the front end of the spray tube is bent at substantially the entire width of the vehicle body, and the front end of the spray tube is turned upward to be in a flip-up state. An embodiment of the present invention will be described below in detail with reference to the drawings. FIGS. 1 and 2 show a powder / granule spraying machine 11, in which a hopper 13 is mounted on a vehicle body 12, and a roll 14 is interposed at an outlet of the hopper 13 to connect one end of a dust discharge pipe 15, 15.

On the other hand, a fan 18 is provided between the hopper 13 and the support frame 16, and power is transmitted from the PTO to the fan 18 via a transmission 19. And fan 1
8, one end of the blower tube 20 is connected, and the other end of the blower tube 20 is connected to the front surface of the central portion of the scatter tube 17. An auxiliary blower tube 21 is connected to the fan 18.
The other end of 1 is connected to the lower part of the roll 14. Most (approximately 80%) of the wind generated by the fan 18 is
Is sent to the central part of the scatter pipe 17, and the remaining wind is sent to the auxiliary blower pipe 21. The spray pipe 17 protrudes left and right from the entire width of the vehicle body 12, and is located outside the support frame 16 and at a position corresponding to substantially the entire width of the vehicle body 12, respectively.
2 is provided. The joint portion 22 has a bellows-shaped flexible tube 23, first arms 24, 24 that support the tube 23, and are rotatable in the vertical direction. The second arm 25 includes the second arm 25. As shown in FIGS. 2 and 3, the first arms 24 provided above and below the flexible tube 23 have a base portion 24a and a tip portion 24b, respectively, and have substantially the same length. The base end 24a and the distal end 24b thus formed are rotatably connected by pins 26, and the distal end 24b is joined and fixed to an annular body 27 surrounding the periphery of the tube 23. The first
The bases of the arms 24, 24 are semicircular bands 28, 28.
The bands 28, 28 are joined and fixed to the scatter tube 17. One end of a push-pull type actuator 30 is pivotally mounted on a frame 29 fixed to the rear part of the vehicle body 12, and the distal end 24 b of the first arm located above the pipe 23 and the annular body 27 The other end of the push-pull actuator 30 is pivotally connected to the joint portion by a pin 31. In this embodiment, the electric motor 30a and the screw type cylinder 30b
Is used, and by rotating the electric motor 30a either forward or reverse, the rod 30c of the screw type cylinder 30b is used.
Is made to expand and contract. However, the present invention is not particularly limited to this, and for example, a hydraulic push-pull type actuator may be used. Second and third surfaces are respectively provided on the front and rear surfaces of the annular body 27.
The base ends of the arms 25, 25 are pivotally connected with pins 32, 32, and the distal ends of the second arms 25, 25 are fixed to semicircular bands 33, 33. Then, it is fixed to the spraying tube 17 by contact. Therefore, the second arm 2
5 and 25 are rotatable about the pins 32 and 32 in the vertical direction. When the rod 30c is contracted by driving the push-pull actuator 30, the joint portion between the distal end portion 24b of the first arm and the annular body 27 is pulled in the direction of the frame 29. The tip 24b rotates about the pin 26. At that time, the first arm 24 bends horizontally and inward of the vehicle body 12 at a position substantially half of the entire length. Since the tube 23 is flexible, the tube 23 is also bent in the horizontal direction together with the first arm 24, and the scatter tube 17 is folded at the joint 22 as shown by a two-dot chain line in FIG. Will be tuned. Therefore, the distal end of the spray tube 17 rotates forward, and is stored horizontally in the left and right sides of the vehicle body 12. Here, as shown in FIGS. 1 and 2, the scatter pipe 1 is located at a position outside the joint portion 22 of the scatter pipe 17.
7, a band 34 is fixed at a position near the tip of the band 7, and the band 3
One end of the wire 35 is locked on the upper part of the wire 4. A band 36 is fixed to an intermediate portion of the scatter tube 17 and a pulley 37 is pivotally mounted on the band 36.
8 and 38 are fixed, and guide rings 39 and 39 are also fixed on both lower sides of the vehicle body 12. And the band 34
The wire 35 is stretched along the scatter tube 17 so that the wire 35 is wound around the pulley 37 and the guide ring 3
The other end of the wire 35 is connected to a manual lever 41 provided near the driver's seat 40 by passing through the wires 8 and 39. When the wire 35 is pulled by operating the manual lever 41, the tip of the spray tube 17 is pulled upward, and the second arms 25, 25 shown in FIG.
It rotates in the vertical direction about 32. Then, as shown by a two-dot chain line in FIG. 2, the flexible tube 23 is bent upward together with the second arms 25, 25, and the scatter tube 17 is bent at the joint portion 22. Therefore, the tip end of the spray tube 17 rotates upward, and is in a state of jumping obliquely upward. A wire 35 extends obliquely upward from the inside of the pulley 37, and the push-pull type actuator 30 is driven to store the spray pipe 17 horizontally to the side of the vehicle body 12. Occasionally, the obliquely stretched wire 35 may hinder the operator from getting on and off.
Therefore, when the scatter tube 17 is stored horizontally, the pulley 37 is positioned slightly behind the driver's seat 40,
The fixing position of the band 36 is determined. Next, a description will be given of small holes formed in the spray tube 17 in some places. As shown in FIG. 4, as well as perforated in an opening 42 at the distal end of the spray tube 17, the lower surface of the spray pipe 17 perforated in the small holes H _1, H ₂ ... H _n at predetermined intervals, the fan The powder and granules 43, 43,..., Which are pumped in the spray pipe 17 by the wind force of 18, are formed so as to be sprayed to the field. Each small holes H _1, H ₂ ... collision plate P ₁ on the inside of the H _n, P ₂ ... P _n
Are fixed, and the angle θ of each collision plate is different. The angle θ of the collision plate is determined by the collision plate P fixed to the foremost small hole H _1.
1 of the angle theta ₁ to the minimum, the angle theta ₂ of the collision plate P ₂ fixedly provided second to the small holes H ₂ from the tip, slightly to larger than the angle theta _1. [0020] Then, with the on the inside of the spray tube _{17, θ 1 <θ 2 <} ...... <θ n the angle of the collision plate theta increased gradually as. Therefore, in the relatively inner part of the spray tube 17, when the powders 43, 43... Collide with the collision plate and are scattered from the small holes, the angle θ of the collision plate is large. 43 fall almost directly below the small hole. On the other hand, in the relatively outer portion of the spray tube 17, the angle .theta. Of the collision plate becomes small, so that the powder and granular materials 43, 43,... You. Further, since the tip of the spraying pipe 17 is tapered and inclined downward, the powders 43, 4 projecting from the opening 42 are formed.
3 are widely spread over a long distance of the vehicle body 12. Therefore, the powders 43 can be evenly spread over a wide range from the inner part to the outer part of the spray tube 17. Next, as shown in FIG.
5 into the spray tube 17 from the powdery granules 43, 43,...
Scatter pipe 17 by wind sent from blower pipe 20
Are spread in the spraying pipe 17 depending on the particle size, amount, specific gravity, etc. of the powders 43. Therefore, the innermost of small holes H _n of the spray tube 17 is in proximity to吐粉pipe 15, and dropped from the small holes H _n While the powder granules 43, 43 ... is not sufficiently diffused, application rates Will cause unevenness. To prevent this, there is the large as possible the distance D between the mounting position of the innermost small holes H _n and吐粉pipe 15 of the spray pipe 17. Further, as shown in FIG.
7 In the innermost small holes H _n of not only fixed the collision plate P _n to the inside of the small holes H _n, is fixed a reflector P _o outside of the small holes H _n . Thus, is powdered or granular material 43, 43 ... part of the drop from the small holes H _n, is reflected by colliding with the reflective plate P _o inwardly of sparge tube 17. Therefore, as described above in FIG. 3, even when the distance D from吐粉pipe 15 to the small holes H _n to the large, rear central part periphery in in powder granules 43 of the body 12, 43 can be sufficiently secured. The present invention can be variously modified without departing from the spirit of the present invention, and it is natural that the present invention extends to the modified ones. According to the present invention, as described in detail in the above embodiment, the first arm and the second arm
Is provided, and the first arm is rotatable in the horizontal direction by the actuator, so that the operator can perform the storing operation of the spray tube without leaving the driver's seat.
