Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor system for transporting a granular substance.

[0002]

2. Description of the Related Art There are various methods for transporting powders and granules, such as a conveyor system such as a belt conveyor and a bucket conveyor, a pneumatic system, and a special pump. It is selected according to the advantages and disadvantages and the characteristics of the object to be transported and the conditions of the installation location. Among these apparatuses, particularly, belt conveyors are currently widely used because they are relatively easy to install and suitable for mass transportation. However, in this belt conveyor, there is a limit to the inclination angle of the belt, and since the belt is used at a gentle inclination, a large space is required, and there are many cases in which peripheral dirt due to falling of a transported object becomes a problem. When transporting at an acute angle is necessary, it is often used together with a bucket conveyor.The bucket conveyor is suitable for vertical transport and efficient, but the equipment is fixed and easy to use. There is a problem in terms. In addition, pneumatic transportation or transportation by a special pump cannot be used in some cases because wear of the device or damage to the transported object may cause a problem depending on the characteristics of the object to be transported. As described above, the conveyor system currently used contains various problems to be improved.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the current conveyor system for transporting particulate matter as described above.
Its purpose is to be able to transport on steep slopes close to vertical,
Easy installation and change of equipment, no drop of transported goods,
It is another object of the present invention to provide a conveyor system that does not damage the package.

[0004]

Therefore, in the chain conveyor of claim 1, two parallel chains 1,
2, a bucket 3 is continuously pivotably installed, and cloth-like sheet members 7 and 8 provided with fasteners 6 at one end on both sides of the bucket 3 are attached. The bucket 3 is covered from both sides and can be opened and closed by a fastener 6. The fastener 6 is closed by a closing slider 10 after a transported object is thrown into the bucket 3 by an input hopper 9, and is closed by a discharge hopper 11. Is opened by the opening slider 12 in front of the vehicle to discharge the transported object.

In the chain conveyor of the first aspect, the fasteners 6 of the buckets 3 installed between the two parallel chains 1 and 2 are closed after the transported goods are loaded by the loading hopper 9. Therefore, even when transported at a steep angle, the transported object does not fall, and efficient transport is possible. Further, since the fastener 6 is opened just before the discharge hopper 11, the transported material is smoothly discharged.

In the chain conveyor according to the present invention, the fastener 6 is formed to have an entire length by sequentially connecting the fasteners 6 manufactured to a predetermined length, and the fastener 6 can be partially removed. It is characterized by having.

In the chain conveyor according to the second aspect, since the fastener 6 can be partially removed, if a failure occurs in the fastener portion during operation,
The failed part can be replaced and easily repaired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the chain conveyor of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view (cross section) showing the entire chain conveyor. After the transported material is put into the bucket 3 by the input hopper 9, the fastener 6 is closed by the closing slider 10, and the bucket 3 moves while being covered by the sheet members 7, 8, and the discharge hopper 1 is moved.
Leads to 1. An opening slider 12 is provided in front of the discharge hopper 11, whereby the fastener 6 is opened, and the transported goods are discharged to the discharge hopper 11. Thereafter, the closing slider 10 installed near the discharge hopper 11
As a result, the fastener 6 is closed again, and the bucket 3 returns to the charging hopper 9 while being covered. Input hopper 9
The slider 12 for opening is installed in front of the zipper, the zipper is opened, and a transported object is loaded.

The above-mentioned chain conveyor is operated by driving two parallel chains 1 and 2 by a pair of driving sprockets 5 installed above the discharge hopper 11. A guide roller 14 is provided at a position where the chain conveyor changes the traveling direction, so that smooth traveling is possible.

The driving sprocket 5 is mounted on an upper frame 15 together with two guide rollers 14,
It is driven by an electric motor 13. The electric motor 13 and the discharge hopper 11 are also incorporated in the upper frame 15, and these devices are integrated as an upper unit. The loading hopper 9 is mounted on a lower frame 16 together with three guide rollers 14, and these devices are integrated as a lower unit.

FIG. 2 is a top view of the periphery of the discharge hopper 11. The electric motor 13 is mounted on the upper surface of the upper frame 15 and drives the drive sprocket 5 by the drive chain 17. Opening slider 12
Is mounted on a bracket extending from the upper frame 15 so that the fastener 6 is opened by movement of the chains 1 and 2. The opened fastener 6 is guided by a plurality of guide pulleys 18 while maintaining the open state, during which the bucket 3 is discharged.

FIG. 3 is a sectional view of the charging hopper 9.
The fastener 6 is opened by an opening slider 12 in front of the charging hopper 9, and the transported material is charged from the charging hopper 9 to the bucket 3. Then, closing slider 1
Although the fastener 6 is closed by 0, the fastener 6 is kept open by the plurality of guide pulleys 18 during the loading of the transported material, as in the discharge.

FIG. 4 is a detailed view of the chains 1 and 2 and the bucket 3. (A) is a top view and (b) is a side view. As shown in the cross section BB, the connecting pins 4 of the chains 1 and 2 pass through the two chains 1 and 2, and the bucket 3 is configured to be pivotable about the connecting pins 4. A fixing projection 19 is formed on a side surface of the bucket 3, and this projection is inserted into a hole provided in a link inside the chains 1 and 2, and the bucket 3 and the chains 1 and 2 are integrated. ing.

FIG. 5 is a detailed view of the fastener 6. The fastener 6 is integrally molded to a fixed length with a flexible resin, and has a structure in which connection portions 20 are formed at both ends. The connecting portions are sequentially connected to make the entire length of the chain conveyor, and the connecting portions 20 can be partially replaced by being disconnected. Also, as shown in FIG. 5, by opening and closing the fastener in the same traveling direction, the fastener 6 can be used as the opening slider 12 and the other as the closing slider 10, as shown in FIG.

According to the above chain conveyor, the bucket 3 is covered with the sheet members 7 and 8,
It can be transported on a steep slope close to a right angle by closing the door, the transported item does not fall, the generation of dust is minimized, and the installation is easy because the upper unit and the lower unit can be installed separately. In addition, the transported item is less likely to be damaged by transport and the device is less worn.
Therefore, the present invention can be provided as a conveyor system suitable for transporting various powders.
