JPS5925501Y2 - Spout tube diversion device for backpack-type power spreader - Google Patents

Description

[Detailed explanation of the device] This device sprays a powdered chemical onto the area from the back of the worker to prevent the worker from adhering the chemical floating in the air to his or her body. This invention relates to a spray pipe turning device for a backpack-type power spreader that can be set and held in any direction, and the spray pipe can be set in front of the operator if necessary.

With conventional backpack-type power sprayers, the jet tube and jet head are located in front of the worker, so when spraying chemicals in the area to be sprayed, the chemicals floating in the air can be sprayed onto the worker's body, especially his face. There is a great danger that some of the particles may fly or adhere to the body and infiltrate the body, harming the health of the work tools, and work safety cannot be fully guaranteed.

Therefore, this design places the jet tube and jet head on the back side of the worker to prevent chemicals floating in the atmosphere from flying directly to the worker's face and attaching to the worker's face while the worker is moving, and to make it easier to orient the jet pipe. This is intended to provide a jet pipe turning device for a convertible backpack-type power spreader, and the device is designed to provide a jet pipe turning device for a convertible backpack-type power spreader. The front ends of the connecting rod and supporting rod set below are removably attached, and the rear end of the connecting rod fixed to the rear end of the supporting rod is rotatably attached to the lower part of the fan case. It is fixed to the jet pipe attached to the machine, and an operating rod is attached to the middle of the support rod.

An embodiment of this invention will be described below with reference to the drawings. A bent pipe 2 is installed inside the distal end of the discharge port 1 of a fan case F which is integrally connected to the lower part of a drug tank T containing a powdered drug (not shown). The upper part is rotatably fitted, and the several bent pipes 2 are extended backwards (in Figures 1 and 2, the left side is the rear and the right side is the front), and a stop such as a hose band is attached at the rear end.゛The front of the bellows pipe 3 is fastened with a fastener (not shown), and the jet pipe 4 is sequentially attached to the rear of the bellows pipe 3. While the jet head 5 is fitted and fixed, the rotary shaft 8 is rotatably inserted through a pair of holding pieces 6 and 7 fixed to the central outer surface of the fan case F with set screws a. The front end of the support rod 9 is removably fitted orthogonally to the lower end of the support rod 9, and the rear of the connecting rod 10, which is removably attached in an inclined manner above the rotating shaft 8, is connected to the support rod 9.
The rear end is connected and fixed with a fastener, and the rear horizontal part 10h of the connecting rod 10 is wound around the jet pipe 4 and the fixed band d is attached.
By attaching the grip part g to the front end of the operating rod 11 which is inserted and tightened inside and whose front end is fixed in the middle of the supporting rod 9, the rotating shaft 8, the supporting rod 9, the connecting rod 10, the operating rod 11. The bent pipe 2, the bellows pipe 3, the jet pipe 4, and the jet head 5 are integrally formed.

Thus, the cover e below the discharge port 1 of the fan case F is fitted and covered over the spacer pipe 2 via the O-ring r, and the bolt j is inserted into the recess () above the bent pipe 2. is inserted to prevent the bent pipe 2 from coming off the fan case F.

In the figure, 12 is a fuel tank, 13 is a motor, 14 is a frame, 15 is a backrest, 16 is a throttle lever, and 17 is a shutter lever.

This idea has the above-mentioned structure, so it can be used in rural areas, vegetable gardens,
When spraying chemicals in areas to be sprayed such as afforestation areas, a worker (not shown) places the product on his back with the back support 15 against his back.
While heading forward (to the right in Figures 1 and 2), start the engine 13 and operate the shutter lever 17 to drop the medicine from the medicine tank T above the bent pipe 2, and at the same time, the fan case F When the pressurized air is sent towards the bent tube 2 by the drive of the bellows tube 3. The water is sprayed from the spray head 5 through the spray pipe 4 onto the area behind the worker.

However, during the lever spraying operation, by rotating the gripping part g in the direction of yl or y2 in FIG. 1, the bent pipe 2. Since the jet head 5 is integrated with the bellows tube 3 and the jet pipe 4 and can be rotated in any desired direction to the left or right, it is possible to spray the chemical at a desired location, or even from behind the worker. As the work is carried out, the sprayed chemicals do not fly directly to the worker's body, especially the face, so there is no risk of chemical damage, and the spraying work can be carried out safely. Connecting rods 10. are connected obliquely and perpendicularly above and below the rotating shaft 8, which is supported substantially vertically on the outside. While the front ends of the support rods 9 are detachably attached, the rear ends of the connecting rods 10 are fixed to the rear ends of the support rods 9, and the rear ends of the connecting rods 10 are fixed to the jet pipe 4, making it easy to perform spraying operations. In this case, unless the operating rod 11 is operated, the rotating shaft 8. A bent pipe 2. is formed by the supporting rod 9 and the connecting rod 10. Bellows tube 3. Since the jet tube 4 and the jet head 5 can be held in their original positions, the direction of spraying the chemical will not change accidentally, which can improve the spraying effect, and when the fan case F is held vertically. , the jet pipe 4 can be maintained substantially horizontally, and the rotating shaft 8. The support rod 9 and the connecting rod 10 can be separated, making it easy to inspect, maintain, repair, replace, etc., making it easy for the user to handle.Furthermore, the overall structure is extremely simple, making it robust and inexpensive. Moreover, since it is easy to operate, it has practical benefits such as being able to widely supply it to general consumers.

Note that the support rod 9 and the connecting rod 10 are separated from each other by detaching the fastener, and the connecting rod 10 is extracted from the band d of the jet pipe 4, and the supporting rod 9. If the front end of the connecting rod 10 is removed from the rotating shaft 8 and the bent pipe 2 is rotated forward relative to the fan case F, the bellows pipe 3. The spray pipe 4 and the spray head 5 are integrally set at the front, and the spraying work can be carried out in front of the operator as in the past, making it convenient for the user to handle them.
