Description

[Detailed explanation of the idea] The present invention relates to a transfer device for grains, etc.

The present invention is intended to provide a simple and inexpensive transfer device that can reliably transfer grains, minimize damage to the quality of the product, and provide a simple and inexpensive transfer device.

BACKGROUND OF THE INVENTION Conventionally, belt conveyors, screw type conveyors, and the like have been used in devices for transporting grains, such as rice, beans, and coffee beans.

The former type of belt conveyor has a driving shaft at one end and a passive shaft at the other end, a belt is wound around the shaft, and objects are placed on the belt and transported.

However, since the belt conveyor is wide, it is heavy and requires a large amount of horsepower.

Furthermore, since the structure is such that the objects to be transported are placed on the belt and transported, the amount of transport is small compared to the area of the belt itself.

In addition, since the screw-type transport device transports the object by the rotation of the screw thread, the object is always in contact with the thread and is unscrewed and transported, resulting in quality loss. Something terrible happened.

The present invention improves the drawbacks of the conventional transportation device, ensures mass transportation and the quality of the transported objects, and provides a lightweight and inexpensive device.

Therefore, the present invention uses a V-belt (connected by a joint) in place of the conventional belt band, and attaches a plurality of rotational resistors to the V-belt, so that the rotational resistance of the V-belt is The aim is to transport objects in an extrusion manner, ensure product quality, and achieve lightweight mass transportation.

Explaining with reference to the drawings, Fig. 1 shows
A horizontally long rectangular tube body 1 made of stainless steel and having a rectangular cross section is shown. On the upper surface of one side of the main body 1,
A hopper 2 for grains, etc. is provided, and a discharge port 3 for the grains, etc. is provided at the other end of the bottom surface of the main body.
Reference numerals 4 and 5 designate pulleys for rotating the V-belt 6 with holes. a passive pulley 5 provided on the hopper 2 side with respect to the pulley 4;
The shaft 8 is pivotally mounted by a pulley position adjustment mount 9 so as to be movable in the length direction of the main body 1. 10 is an adjustment screw. As seen in FIG. 3, the V-belt 6 is
By forming a large number of mounting holes 11 passing through the V-belt 6 in the vertical direction at regular intervals, and attaching the connectors 14 to both ends 12 and 13 of the V-belt 6, one annular endless V-belt with holes is formed. Belt 6 and eggplant. The coupling tool 14 has a chain piece 15 in the center, and a pair of left and right U-shaped fittings 16, 1 are attached to the chain piece 15.
The V-belt 6 is held in a ring shape so as to be bendable via the chain piece 15, and a plurality of tension pulleys 17 are attached to the upper surface of the descending belt 18. This prevents it from lifting up. An arbitrary number of L-shaped mounting bases 19 made of hard synthetic resin are mounted at arbitrary positions in the large number of mounting holes 11.

The L-shaped mounting base 19 crosses the V-belt 6 in a cross shape. A scraping blade 21 made of soft synthetic resin is brought into contact with the side surface of the vertical part 20 of the L-shaped mounting base 19, a fixing plate 22 is brought into contact with the outside thereof, and the three are fastened together with a stopper 23. do.

As seen in FIG. 5, the U-shaped metal fittings 16, 16' are made by bending a single plate formed by press working between an upper surface 24 and a bottom surface 25.
is formed to be wide so as to come into contact with the wide upper surface of the V-belt 6, as shown in FIG.
The bottom surface 25 is arranged so as to be in contact with the bottom surface of the narrow part of the V-belt 6 and the shaft 3 of the chain piece 15.
It is narrowly formed so that it can be hung around 3. If a thread groove is cut in the mounting screw hole 27 formed on the bottom surface of the mounting screw holes 26 and 27 of the U-shaped fitting, the screw 32 can be omitted.

As mentioned above, the scraping blades 21 are made of soft synthetic resin, and are attached to both the front and rear walls 2 of the main body 1.
The horizontal width is slightly larger than the inner width of the main body 1, and the main body 1 is moved so as to rub against the bottom surface 28, which is formed in a long plane except for the curved portion 34.

In addition, the coupler 14 is attached to the V-belt 6 without contacting the pulleys 4, 5, as shown in FIG. 4, in order to rotate together with the V-belt 6 by the pulleys 4, 5. A gap 35 is formed below the center side between the V-belt 6 and each pulley 4, 5.

The position adjustment mount 9 of the passive pulley 5 is
Both the front and rear walls 29, 3 of the main body 1 are installed so as not to impede the rotation of the scraping blade 21 attached to the belt 6.
The position of the driven pulley 5 is adjusted by rotating the screw 10.

Next, the operation of the present invention will be explained.

When grains, etc. are fed into the main body 1 from the hopper 2, the grains, etc. are held in an annular shape within the main body 1 by a coupling device 14, which has a much smaller area than a flat belt, and are transferred to the driving pulley 4. Therefore, the grains, etc., fall onto the bottom surface 28 without being hindered by the V-belt 6 rotating as if being pulled from the discharge port 3 side (without the grains accumulating on the V-belt 6), and the particles of the main body 1 are It accumulates on the bottom surface 28. In this case, among the input grains, etc., those accumulated on the belt while the upper part is rotating, when the lower part is rotating, all the accumulated grains, etc. fall toward the bottom surface 28, and Even when the descending belt 18 is accumulated on the lower part rotating or on the L-shaped mounting base 19, when the descending belt 18 is moved upward after passing the mounting shaft 7 of the drive pulley 4, the descending belt 18 , and most of the accumulated grains etc. on the L-shaped mounting base 19 are discharged from the outlet 3.
The grains, etc. that have fallen toward
Due to the gap between the tension pulley 17 and the tension pulley 17, which is formed in the same way as the
fall towards.

Next, the grains etc. accumulated on the bottom surface 28 of the main body 1 are
The V-belt 6 has a width slightly larger than the width between the front and rear walls 29 and 30 of the main body 1.
Scraping blades 21 arbitrarily attached to mounting holes 11 provided at regular intervals are urged downward by a plurality of tension pulleys 17 to scrape the bottom surface 28 of the main body 1. Therefore, it is pushed out to the discharge port 3 without leaking from both left and right end sides of the scraping blade 21.

However, since the scraping blades 21 are made of a soft synthetic resin, product quality damage caused by the belt conveyor is much less than in conventional conveying devices using screws. Moreover, the curved portion 34 formed on the side of the passive pulley 5 of the main body 1 allows the scraping blades 21 to push out every grain of grain.

Even when a large amount of grain is fed into the main body 1 from the hopper 2, the grain does not overflow to the left and right sides of the belt like in conventional belt conveyors, but only overflows over the top of the raking blades 21. Therefore, it is returned to the bottom surface 28 and the next scraping blade 21
During the scraping operation, it is transported and pushed out to the discharge port 3.

As shown in FIG. 2, the grain transporting device according to the present invention is capable of transporting grains in an upward direction even at an angle of about 30 degrees.

As explained above, the present invention makes it possible to minimize the destruction of product quality such as grains during transportation by first of all using soft synthetic resin scraping blades, and also to prevent the destruction of products such as grains during transportation. On the other hand, by pushing out the accumulated grains in a sweeping motion, it is possible to eliminate any leakage of the grains, etc., and make it possible to transport them in large quantities.

Second, by using a V-belt with many mounting holes instead of a flat belt, the grain body 1
grains, etc. can be easily accumulated on the bottom surface of the belt, the weight of the pulley and the belt itself, and the belt guide plate can be reduced compared to the case of a flat belt, and the number of attachment points can be reduced. By using the holes, the scraping blades can be arranged at desired intervals,
It is possible to cope with the amount of grain to be transported.

Thirdly, the present invention eliminates the need to manufacture a special coupling device by using an item equivalent to a chain piece or a chain piece as the main part of the V-belt coupling device.
