DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The powder and granule applicator described in JP-A No. 2-135019 and Japanese Utility Model Publication No. 4-7694 is such that the powder or granules are placed on the bottom corner of the bottom of the bag. It is connected with a spray pipe. The spray pipe of such a duster is connected to either the left or right corner corresponding to the dominant arm when carrying on the back and spraying, and the right-handed person should connect to the right corner. , Left-handed people select and use the one connected to the left corner, for example, if you hold the spray pipe connected to the right corner with your left hand, the corner near the bottom of the bag will bend. Then, the flow of powder and granules was obstructed, and it became impossible to spray.

Further, in the bag body in which the spray pipe is connected to one corner of the bottom side of the bag body, the powdery particles easily accumulate on the other side of the bag bottom. It was difficult to use because the sprayer would not flow into the spray tube unless it was tilted to one side or shaken.

[0006] Further, in this powdery or granular material sprayer, when changing the type of powdery or granular material during spraying, the previous powdery or granular material must be opened from the bag and filled with the next powdery or granular material each time. It is very troublesome because it has to be done.

The opening and closing means of the spray tube in the powder and granular material spreader described in Japanese Utility Model Publication No. 4-386611 is provided with a rotating shaft having a lever at one end thereof penetrating along the diameter of the spray tube. A disk with a size that can close the inside of the spray tube is attached to this rotating shaft, and the disk is formed so as to be rotatable around the rotating shaft by the operation of the lever. When rotated to, the peripheral edge of the disc contacts the inner peripheral surface of the spray tube to close the spray tube, thereby stopping the outflow of the powder or granules, and when rotating the lever in the opposite direction, The disc rotates 90 degrees from the closed position to open the spray pipe, thereby releasing the outflow of the powder and granules.

However, when the lever is rotated in one direction to bring the peripheral edge of the disk into contact with the inner peripheral surface of the spray tube, such an opening / closing means causes the particulate matter to surround the peripheral edge of the disk and the inner peripheral surface of the spray tube. It easily clogged with the surface, obstructing the clogging of the spray tube, and leakage of powder and granules often occurred.

Therefore, in view of the above-mentioned problems, the present invention can be used without trouble with either the left or right hand, and it is possible to smoothly guide the powdery or granular material to the spraying pipe, and further, during the spraying. It is not necessary to discharge the previous powder and granules from the bag to fill the next powder and granules in order to change the type of powder and granules.
The present invention has been devised as a subject to provide a powdery or granular material spreader capable of reliably closing the spraying pipe by the opening / closing means.

[0010]

For this reason, the present invention is directed to a backpack plate having a backpack belt, and a lower funnel-shaped plate with its lower portion gradually converging toward the supply port at the center of the bottom surface. In addition to a powder / granule storage container that is detachably attached by a mounting means, a nozzle is provided on the tip end side, and a bent tube is bent at a substantially right angle on the base end side. A cylindrical spray tube rotatably connected to the supply port of the article storage container by a connecting means and provided with an opening / closing means at an appropriate position, and a means for attaching the backpack plate and the powder or granular material storage container. Extends a mounting plate that stands up on the non-back surface side on the upper left and right edges of the backpack plate, and has insertion slits formed in the mounting plate in the longitudinal direction. Is provided with an insert piece that can be inserted into the insert slit, and further, a backpack plate and powder particles Each of the storage container is formed with a screw hole, the insertion piece is inserted into the insertion slit, and the fixing screw is inserted through the screw holes, and the connecting means between the bent tube and the powder or granular material storage container is formed. Extending only the periphery of the opening of the bending pipe to form a hooking edge so that the outer diameter becomes large, while attaching a connection ring that can insert the bending pipe to the supply port of the powder or granular material storage container and connecting it. A convex strip is formed on the inner peripheral surface of the ring so that the hooking edge of the bending tube cannot be inserted, and the bending tube is inserted from the inside of the powder and granular material storage container into the connecting ring to project the hooking edge. The fixing ring having a shape in which the inner peripheral surface is gradually reduced downward is fixed at a position above the hooking edge portion of the inner peripheral surface of the connecting ring, and the fixing ring and the ridge are provided. The hooking edge portion is sandwiched between the opening and closing means of the spray pipe, and the arc edge of the spray pipe is joined to the inner peripheral surface of the spray pipe. And a semicircular closing plate integrally formed so that it is slidably rotatable on one side of the closing plate about the center of the arc of the semicircle of the closing plate and faces the closing plate. Side semicircular opening can be closed, and a sliding plate that is rotatably arranged outside the spray pipe and that is connected to the sliding plate and can operate the sliding plate. The above problem is solved by forming the sliding plate so as to be continuously rotated by the operation ring from the position where the opening is closed to the position where it is rotated by 180 degrees.

[0011]

According to this invention, however, the backpack plate and the powder / granule storage container are provided with screw holes by inserting the insert piece of the powder / granule storage container into the insertion slit formed in the mounting plate of the backpack plate. It is attached by inserting a fixing screw between them, and is removed by removing the screw and removing the insertion piece from the insertion slit.

Further, the lower part of the powdery or granular material storage container formed in a funnel shape so as to gradually narrow toward the center of the bottom surface automatically guides the powdery or granular material to the spray pipe connected to the center of the bottom surface.

Since the bending pipe is rotatably connected to the supply port of the powdery or granular material storage container by the connecting means, the spreading pipe can be freely oriented in any direction to smoothly perform the spraying work. Also, since the bent tube is connected to the center of the bottom surface of the powder or granular material storage container, the operator can use the spray tube by turning it forward from either the left or right side of the body.

Further, the opening / closing means provided at an appropriate position of the spray pipe, when the sliding plate is rotated to a position for closing the semicircular opening on the side facing the closing plate, the powdery or granular material Is completely stopped, and while the sliding plate is continuously rotated from that position, the opening is gradually opened to allow the granular material to flow out.

Further, the stationary ring smoothly guides the powder or granular material in the powder or granular material storage container to the bent tube by the inner peripheral surface which is gradually reduced downward.
