Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a suction conveyor that sucks up rice husks discharged from a rice huller, for example, and discharges the rice husks to a distant place for processing.

[Conventional technology and issues]

Conventionally, for example, a suction conveyor that sucks up rice husks discharged from a rice huller and discharges them to a distant place has a thrower structure, more specifically, a lifting cylinder installed in the centrifugal direction on one side of a flat cylindrical body. A rotary impeller that stands upright and rotates at high speed is disposed inside the flat cylindrical body, and an opening is provided in the center of one side of the flat cylindrical body,
This opening is connected to a suction case having a large-diameter suction cylinder connected to a suction pipe on one side wall. This structure has a problem in that it can only be used for discharging rice husks that are directly connected to the huller. In other words, it is possible to effectively suck up the rice husks released from the rice hulling machine and dispose of them at a distant location, but it is impossible to treat the dust that is generated during the hulling process and accumulates in the workplace. Currently, these dust particles are disposed of manually.

The purpose of the present invention was made in view of these circumstances, and is to provide a suction conveyor that solves the problems of the conventional technology by simple yet rational means, and that saves labor and improves cleaning efficiency. This is what I am trying to do.

[Means to solve the problem]

The structure of the present invention that solves the problems of the prior art is that a lifting cylinder is erected in the centrifugal direction on one side of a flat cylindrical body, a rotor wheel that rotates at high speed is disposed inside the flat cylindrical body, and the above-mentioned In a suction conveyance machine, a suction case is provided with a passage in the center of one side of a flat cylindrical body, and a suction case having a large-diameter suction cylinder to which a suction pipe is connected to the side wall of one side is connected to the suction case. is removable from the suction case, a porous plate member is replaceably attached to the large diameter opening formed in the suction case, and the wall of the suction case is provided with the large diameter suction tube. A small-diameter suction cylinder is removably provided on the other side wall perpendicular to the side wall, and a porous plate member is replaceably attached to the small-diameter opening formed in this side wall. The present invention is characterized in that a partition plate is provided which is located between the large diameter opening and the small diameter opening and is inclined toward the opening of the flat cylindrical body.

〔Example〕

The details of the embodiments will be explained with reference to the drawings.

A lifting tube 4 to which a long ejection tube 3 is connected is erected on one side of the flat cylindrical body 2 in the centrifugal direction. 5 is installed inside. In the figure, 6 is a bearing metal provided on one side wall of the flat cylindrical body 2, 7 is a rotating shaft, and 8 is a pulley. A relatively large-diameter port 9 is formed in the center of the other side wall of the upper flat cylindrical body 2, and a cubic-shaped suction case 10 is connected to the port 9.

A large-diameter suction tube 11 is detachably attached to the top wall 10a of the suction case 10, and the tip of the large-diameter suction tube 11 faces the chaff discharge section of a rice husking machine (not shown). The rear end of the hose 12 is detachably connected. A small-diameter suction cylinder 13 is attached to the front wall 10b of the suction case 10 adjacent to orthogonally to the top wall 10a.
3 is removably connected to the rear end of a flexible hose 14 having a suction port 14a attached to its tip.

The large diameter suction tube 11 is formed by a short tube 11a to which the rear end of the hose 12 is detachably attached, and a short attachment tube 11b having a larger diameter,
The lower end of this short tube 11a is fitted into the upper end of the short mounting tube 11b, and both tubes 11a, 11b
are connected by connecting fittings 11c, and both cylinders 1
Between 1a and 11b, there is an auxiliary intake port 11d for relaxing the suction force of the rotary impeller 5 and preventing the paddy from being sucked and removed together with the rice husks from the rice husking machine to which the hose 12 is connected. It has been formed. Further, reference numeral 14b in the figure is a regulating plate for holding the suction port 14a upward.

A shaft 15 is rotatably attached to the inside of the corner at the boundary between the top wall 10a and the front wall 10b that constitute the suction case 10, and the shaft 15 has the large diameter and small diameter suction cylinders. The partition plate 1 is located between the large-diameter opening 11e and the small-diameter opening 13a where the 11 and 13 communicate, and is inclined downward toward the passage 9 of the flat cylindrical body 2.
The upper end of 6 is fixed. Pins 17 are attached to the side walls 10c of the suction case 10, and these pins 17 connect to the partition plate 16.
The pins 17 are provided in an arcuate guide hole 18 centered on the shaft 15, and each pin 17 has a tightening nut 19 screwed into the partition plate 16. The lower end can be rotated to adjust the angle. That is, if the blower of the rice husking machine is weak, the partition plate 16 is rotated upward to narrow the space between it and the large diameter opening 11e, thereby adjusting the suction by the blower to be small.

In addition, when collecting and discharging rice husks from the hose 12, the small diameter suction cylinder 13 is connected to the suction case 1.
0 and close the small diameter opening 13a with a porous plate member 20. Also, when using the small diameter suction tube 13 and flexible hose 14, remove the large diameter suction tube 11 from the suction case 10. After removing it, the large diameter opening 11e is closed with a porous plate member 21.

[Effect]

For example, when husking work is performed using a husking machine in a workshop, the tip of the hose 12 is placed so as to face the rice husk discharge port of the husking machine. At this time, the first and second
As shown in the figure, the small diameter opening 13a is closed with a plate member 20, and the air inside the hose 12 is forcibly sucked through the suction case 10 by the suction action generated by the high-speed rotation action of the rotary impeller 5, and the rice husks are separated from the partition plate. The rice husks are discharged far from the lifting tube 4 and the discharge tube 3 while being guided along the surface.

When the work is completed and the work area is cleaned, the large-diameter suction tube 11 is removed and the large-diameter opening 11e is opened.

〔effect〕

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Rice husks released from working machines such as rice husking machines are forcibly sucked through a large-diameter suction cylinder by the action of the rotary impeller that makes up the thrower structure, and then (b) A large-diameter suction tube and a small-diameter suction tube are provided separately on adjacent walls of the suction case, and the suction tube is located between the two, and Since a partition plate is provided that slopes toward the outlet of the flat cylindrical body, the rice husks and dust that are sucked in from each suction tube, which is operated separately, are efficiently guided to the outlet along the plate surface of this partition plate. ,
No accumulation within the suction case.

(c) Since either the large-diameter port or the small-diameter port is closed by a porous plate member when not in use, separate suction operations can be performed effectively, and an appropriate amount of air can be taken in through the plate member. The work environment can also be cleaned.
