Abstract

PURPOSE:To prevent a noise and a crush of granular bodies from occurring, by installing a medium node entering in a projection port and another medium node entering in discharge port parallelly with each other, besides in the reverse direction, while forming a conveying section between both medium nodes, in case of a conveyor for a grain of rice or the like. CONSTITUTION:Having guided by a guide 36 and pressed against a belt 25 so far, a conveying body 26 stands upright to the belt 25 at a projection port 3, comes into a state of readiness for conveyance immediately after dipping up a granular body 2 and at the position of a driven pulley 29 of a second wrapping device 22, the conveying body 26 is supported upward from beneath by a projecting piece 34 of a belt 32, so that while the conveying body 26 is in a state of upholding the granular body 2, a conveying section 35 is formed between both belts 25 and 32. And, a conveyed load 2 is carried up to a discharge port 4 and discharged out to a discharge port 33 from the conveying body 26. With this constitution, the reversion of the granular body can be prevented and a noise and a crush of granular bodies in time of high speed conveyance can be prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a granular material conveying machine used for transporting granular materials such as rice grains and wheat grains.

As a conventional powder conveyor of this type, there is one that uses a packet conveyor 1 as a conveying means, as shown in FIG. 1, for example. That is, the packet conveyor 1 is disposed inside a casing 5 having an input port 3 and a discharge port 4 for the powder and granular material 2, and a belt 8 is used as a mediating joint between the upper and lower two pulleys 6 and 7. A winding device 9 is configured by winding around the belt 8, and a large number of packets 10 for transporting the powder and granular material 2 are attached to the belt 8.
These packets 10 are circulated together with the belt 8 to transport the powder and granular material 2.
The waste enters the casing 5, is scooped up into the bucket MO one by one, is conveyed toward the upper pulley 6, and is transferred to the upper boolean IJ.
When the packet 6 moves in an arc shape, the centrifugal force generated on the packet 10 causes the powder 2 to be thrown out toward the jaw plate 11 forming the discharge port 4 of the casing 5.
Make sure it is taken out.

However, in the packet conveyor 1 as a conventional powder or granular material conveyor, although the conveyance capacity of the powder or granular material 2 can be increased by increasing the moving speed of the belt 8; All of the powder and granular material 2 inside is discharged from the outlet 4.
A so-called "return 9" phenomenon occurs in which the packet 10 passes the dischargeable position and falls toward the bottom of the powder bowl 8 casing 5 before being discharged from the powder bowl, and the increase in conveyance efficiency is suppressed accordingly. There was a problem. If the moving speed of the belt 8 is made too fast, a strong impact will be applied to the powder and granules 2 when they are thrown onto the jaw plate 11 of the discharge port 4, causing rice grains, wheat grains, etc. In some cases, fine cracks occur on the surface or inside of the grains, making them more likely to break into pieces, resulting in a loss of taste. Furthermore, there was also the problem that large noises were likely to be generated due to the 6.70 rotations of the pulley, the movement of the belt 8, and the collision between the granular material 2 and the jaw plate 11. This invention solves these conventional problems. It was developed with the aim of solving the disadvantages of conventional methods by increasing the conveyance capacity without increasing the moving speed and eliminating the generation of "return" phenomenon, crushed particles, noise, etc. In a powder conveyor which is equipped with a powder inlet and an outlet, and a means for transporting the powder into a casing, the conveying means carries a flat conveyor. It has a first winding device which allows a large number of floating media nodes to face the powder or granular material input port, and a media node that rotates in a direction substantially parallel to and opposite to the media node of the first winding device, and the media A second winding device is provided with a discharge part of the powder and granular material formed at one end side by a knot and facing the discharge port, and the powder and granule are delivered to the internodes of both media by the rise of each of the conveying bodies. It is characterized by the fact that the conveyance section can be freely formed.

Hereinafter, this invention will be described based on an embodiment shown in FIGS. 2 to 4. Hereinafter, parts that are the same or similar to the conventional ones will be given common reference numerals, and redundant explanation will be omitted.

In the figure, reference numeral 20 denotes a conveying means, which is mainly composed of a first winding device 21 and a second winding device 22. Both the first and second winding devices 21 and 22 are arranged parallel to each other into the casing 5. It is located in

The first winding device 21 has a belt 25 between a driving pulley 26 and a driven pulley 24 disposed at upper and lower positions in the casing 5.
A large number of conveyors 26 are attached to this belt 25, and the belt 25 is placed near the drive pulley 26 to face the inlet 3 for the powder and granular material 2. The conveyor 26 is a flat plate material, one end 26a of which is bent as shown in the figure, and has holes 2 provided at regular intervals in the belt 25.
By inserting this one end 2/)a into the belt 7, it is placed in a loose state so that it can move freely while being attached to the belt 25, as shown in FIGS. 3 and 4. In addition, since the carrier 26 is installed in this way, removal and installation are as follows.
This can be done by simply pulling out and inserting into the belt 25.

The second hoisting device 22 includes a drive pulley 28 and a driven pulley 29 arranged at upper and lower positions in the casing 5, two auxiliary boots J30 and 61 arranged near the drive pulley 28, and furthermore, these pulleys. The belt 32 is lifted up between 28.29 and 30.31 to serve as a "mediate joint".

This belt 32 is rotated approximately perpendicularly to the auxiliary pulley 30, and further passes through another auxiliary pulley 61 to drive 7"-!J28.
It is being hoisted back to. And the second winding device 22
A discharge part 33 for the powder or granular material 2 is formed at one end side, and this discharge part 66 faces the discharge port 4 for the powder or granular material 2. Further, this belt 62 is entirely arranged substantially parallel to the belt 25 of the first winding device 21, and its rotation direction is opposite to the rotation direction R of the belt 250.

In the figure, reference numeral 64 denotes protrusions, one of which is provided on the belt 32, and when the carrier 26 reaches between the two bells 25 and 12, its tip 26b is placed on one of the corresponding protrusions 64. It is designed to be locked. And from this, carrier 2
6 stands up with the movement of both belts 25.32 and moves in a ladder-like manner as shown in the figure, and can freely form a plurality of conveying sections 65 for powder and granular material 2 between both bells 25.52 facing each other. This is what it says. In the illustrated example, the belt 25 of the first winding device 21 and the belt 32 of the second winding device 22 rotate slightly faster. And the second winding device 22
At the position of the auxiliary boot IJ 50, the side of the first winding device 21 of the conveyor body 260 is lowered so that the conveyance section 35 has a hairstyle, and the above-mentioned protrusion 34 according to the conveyance of the powder and granule material 2 is lowered.
We are trying to reduce the load on the. Of course side bell) 25
．． The rotational speeds of 32 may be the same.

In the illustrated example, the discharge section 66 for the powder or granular material 2 is approximately horizontal, but it may of course be buttoned so as to have a downward slope.

In the figure, reference numeral 36 denotes a first guide body, which is fixed to the casing 5 at a position above the input port 3 for the powder and granular material 2, and the conveyor 26 that has passed the drive boob 923 position of the first winding device 21 While the powder and granular material 2 reaches the inlet 6, the conveyor 26 is moved by the belt 25.
It is designed to be pressed with a groove in a substantially parallel state to the surface. Reference numeral 67 in the figure denotes a second guide body, which is disposed at a position that substantially contacts the back side of the belt 25 of the first winding device 21 on the side facing the second winding device 22; One end 26a of the conveying body 26 forming the conveying section 65 is clamped together with the belt 25, so that the conveying body 26 is made to stand approximately upright with respect to the belt 25.

In the illustrated example, the first and first winding devices 21 and 22 are "
Of course, various "conveyor devices" such as "chain conveyor" and "cable conveyor" can also be used, and the present invention is not limited to the illustrated example. As the conveyor body 26, various shapes can be used as long as it has a flat part.Next, the operation will be explained.1. When the conveyance body 26 reaches the inlet for the powder and granular material 2, it rotates to stand upright with respect to the belt 25.

The powder 2 from the input port 6 is received by a conveyor 26 that stands upright with respect to the belt 25, and moves as the belt 25 rotates.

Then, as described above, the space between the two conveying bodies 26 that sequentially moves is filled with the powder or granular material 2. The conveying body 26 which has further rotated and reached the position of the driven boob 929 of the second winding device 22 is supported from below by the projecting piece 64 of the belt 62 and is in a locked state. Conveyor 26 and both bells) 25, 32 together with powder and granular material 2
A plurality of conveyance sections 35 are continuously formed.

Further, the movement continues and the auxiliary boot 960 of the second winding device 22
The conveyor 26, which has slightly passed the position, falls downward due to the weight of the powder and granules 2 (see the arrow X in FIG. 1), and the powder and granules 2 are therefore transferred onto the discharge section 63 and are sequentially discharged. It is discharged from the device through the outlet 4.

In addition, when the powder and granular material 2 is intermittently introduced, the transport section 65 will be partially formed, but in this case, the transport section 65
This only forms an ``empty conveyance zone,'' so to speak, and has no effect on conveyance. Furthermore, it goes without saying that this device can be used in any direction, vertically, horizontally, or diagonally.

Since the powder and granular material conveying machine according to the present invention is as described above, the powder and granular material that has been transported in the conventional manner is transported in the opposite direction.
However, since the powder or granular material can be conveyed continuously without interruption, it can be compressed to death even if the mediating joint such as a belt is rotated at low speed, and has a sufficiently large conveying capacity. Therefore, the device can be operated without causing crushed grains or noise due to high-speed conveyance, and has many effects such as not deteriorating the taste when conveying rice grains, wheat grains, etc.1. According to the embodiment, since the conveyor can be easily removed and attached, maintenance and maintenance can be easily performed when the conveyor is damaged.
