BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a suction transfer device for transferring a light conveyed object such as rice hulls and leaves to a distant place.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional suction conveyance device. In this apparatus, a blower impeller 2 is provided in a case 1 having a circular front shape on a table, and a discharge tube 3 for connecting a long transfer hose (not shown) in one side of the case 1 in a centrifugal direction is formed. At the same time, a relatively large-diameter suction port 4 is provided at the center of one side wall of the case 1 and is surrounded by an inclined wall as shown in the figure for supplying conveyed objects such as rice husks and leaves on the outside of the suction port 4. The supply hopper 5 is provided.

[0003]

The above-mentioned conventional suction and transfer apparatus has the following problems. When a large amount of conveyed objects such as rice husks and tree leaves are put into the supply hopper 5, the suction port 4 is temporarily closed, so that the outside air required for the bouncing and transporting is not introduced, and the bouncing force of the blower impeller 2 causes Occurs, which can only be transported.
The conveyed object stays in the transfer hose, and even if the suction port 4 is released from being clogged, the stagnant sequentially grows due to the conveyed object that has stagnated first, and finally the conveyance becomes impossible. Sometimes. In order to avoid such a blockage of the suction port 4, the above-mentioned problem can be solved by feeding a small amount of the conveyed object into the supply hopper 5. A new problem arises in that efficiency is reduced and a physical burden is imposed on the operator.

An object of the present invention is to supply a supply hopper for a conveyed object through a suction cylinder provided with an outside air suction port at a required position, so that a large amount of conveyed object is supplied to the supply hopper. Prevents the mouth from being blocked and allows the transported object to be continuously introduced from the suction port by the action of the external air sucked from the external air intake port, making it possible to efficiently transport the transported object without clogging by the blower impeller. An object of the present invention is to provide a suction conveyance device which can be performed well.

[0005]

Means for Solving the Problems According to the structure of the present invention, which solves the problems of the prior art, an impeller is provided in a case having a circular front shape on a table, and a discharge cylinder is formed in a centrifugal direction on one side of the case. In addition, in the suction and conveyance device in which a suction port for supplying a conveyed object is formed at the center of one side wall of the case, the outside air suction port is substantially the same shape and size as the suction port, and is provided at a required position. An open end of the provided suction tube is connected to the suction tube, and a supply hopper for a transferred object is provided in the suction tube.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a partially cutaway front view, and FIG. 2 is a partially cutaway plan view of the same.

A discharge blower A having a slower structure is mounted on a carriage 13 provided with a push operation handle 11 on one side and wheels 12 on the lower surface.

[0008] The discharge blower A is configured as follows. Reference numeral 14 denotes a case having a circular front shape.
4, a drive shaft 1 is mounted on one side wall of the case 14.
A blower impeller 16 provided at the inner end of 5 is provided.
A pulley 17 is fixed to the outer end of the drive shaft 15. The pulley 17 is connected to a pulley 19 of a motor 18 mounted on the carriage 13 via a belt 20, and is connected to the blower impeller 16. High-speed rotation drive is transmitted. A discharge tube 21 is provided in one side of the case 14 in a centrifugal direction. The discharge tube 21 is provided with a flexible lightweight transfer pipe 23 made of synthetic resin or the like via an elbow-shaped connection tube 22. One end is detachably connected.

On the other hand, the other side wall of the case 14 has a relatively large suction port 24 centered on the axis of the drive shaft 15.
Outside the suction port 24, a number of outside air suction holes 25b are formed in an outer end face wall 25a, and the opening of a suction cylinder 25 having the same diameter as the suction port 24 is continuously connected. In addition, a supply hopper 26 for a transferred object is provided above the suction tube 25. 27 is a shutter and the shutter 2
Step 7 adjusts the amount of the transferred object to be supplied into the supply hopper 26 into the suction tube 25. Reference numeral 28 in the figure denotes leg members for attaching the case 14 to the carriage 13. The discharge blower A is configured as described above.

In the above embodiment, the motor 18 is used as a power source of the discharge blower A. However, since the motor 18 can be used in a place where no power is supplied, an engine (not shown) may be mounted instead of the motor. Since it is possible, the motor is not specified as the power source. In addition, by providing the outside air suction hole 25b in the outer end wall 25a of the suction tube 25, it is possible to supply the transported object linearly into the case 14 through the suction port 24 by the sucked outside air flow. Also, since there is no possibility that the conveyed object leaks outside, there is a feature that the hole diameter of the outside air suction hole 25b can be increased. However, by reducing the hole diameter to prevent the conveyed object from leaking outside. Since the outside air suction hole 25b can be provided in, for example, the lower cylindrical wall of the suction tube 25, the formation site of the outside air suction hole 25b is not limited to that of the illustrated embodiment.

[0011]

When the blower wheel 16 is rotated at a high speed by the motor 18, outside air is introduced from the supply hopper 26 and the outside air suction hole 25b. In this state, when an object to be conveyed such as rice husks or tree leaves is supplied to the supply hopper 26, the object to be conveyed is supplied into the suction cylinder 25, and even if a large amount is introduced, the suction port 24 is closed by the object to be conveyed. There is no.
On the other hand, the conveyed object supplied into the suction tube 25 is continuously sent into the case 14 by the external air flow introduced from the external air suction hole 25b, and the strong conveying force and the wind force of the blower impeller 16 are provided. Thus, the sheet is conveyed to a distant place (for example, 100 m) via the discharge tube 21, the connection tube 22, and the transfer pipe 23.

As described above, according to the configuration of the present invention, the following effects can be obtained. (A) Since the conveyed object put into the supply hopper is guided to the suction port of the case through the suction cylinder, even if a large amount of conveyed object is input, the conveyed object is kept in the suction port as in the related art. It is possible to perform a smooth long-distance transport process without temporarily blocking the transported object and clogging the transported object in the transport pipe. (B) Since the outside air suction hole is provided in the suction tube, the conveyed object supplied into the suction tube by the outside air flow sucked from the outside air suction hole is conveyed by this outside air flow and wind action by the blower impeller. Since the object can be effectively and surely carried out to a distant place, the size and weight of the apparatus itself can be reduced, and the handleability can be improved.
