Abstract

(57) [Abstract] [Purpose] To provide a conveyor device for conveying foundry sand which has a simple structure that is easy to manufacture without impairing the transfer function of the conveyer and can easily collect the foundry sand spilled. To aim. [Structure] A sand receiving plate / frame 3 formed by bending a steel plate into a rectangular shape having an average top surface is provided on one side of a bridge plate 2 configured as a platform. A conveyor device for conveying foundry sand, which comprises a belt conveyor on the upper part of the frame 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor device for transporting foundry sand used and recovered in a casting facility.

[0002]

[Prior art and problems]

 Conventionally, a belt conveyor has been used as a conveyor device for conveying foundry sand, but this belt conveyor is entirely made of shaped steel, and has a structure in which a roller is supported up and down to hang the belt around. There is. In such a belt conveyor, a part of the foundry sand adheres to the belt and is transferred to the return side, where it is spilled by the return roller part. The foundry sand spilled in this way entered a narrow and complicated place made of shaped steel, and the work to recover it was extremely troublesome. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a foundry sand conveyer device capable of easily collecting spilled sand.

[0003]

[Means for solving problems]

 In order to achieve the above object, a conveyor device for conveying foundry sand according to the present invention is a sand formed by bending a steel plate on one side of a bridge plate configured as a platform to make the upper surface flat and rectangular. A frame that also serves as a receiving plate is provided, and a plurality of supporting frames are provided on both sides of the frame that also serves as a sand receiving plate so as to oppose each other at appropriate intervals, and the upper position of the opposing supporting frame. It is characterized in that a roller on the feeding side of the belt is mounted between the rollers and a roller on the returning side of the belt is provided between the lower positions of the supporting frames facing each other.

[0004]

[Action]

 By adopting the above-mentioned solution, the present invention can make the structure simple and easy to manufacture without degrading the function of the conveyor, and the spilling foundry sand is formed on a flat surface. Collecting on the frame that also serves as a sand receiving plate facilitates collection work.

[0005]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a bridge plate 2 is attached to the upper surface of the right half of a base frame 1 arranged at appropriate intervals in the front-rear direction for use as a platform plate for workers. On the upper surface of the left half of the frame 1, there is attached a frame 3 also serving as a sand receiving plate, which is formed by bending a steel plate into a flat upper surface. A plurality of mounting frames 4.4 are fixed to the upper part of the sand-receiving plate / frame 3 at appropriate intervals in the front-rear direction, and both ends of the mounting frame 4.4 are fixed. Supporting frames 5.5, each having a tip bent inward, are erected so as to face each other.

An auxiliary frame 6.6 is installed at an intermediate position between the supporting frames 5.5 facing each other, and a space between the tip of the supporting frame 5.5 and the auxiliary frame 6 is provided. Feed roller 7.8. 9 are rotatably mounted via brackets 10.10 and form a U-shape on the upper surface of each feed roller 7.8.9. Further, a return-side roller 11 is rotatably supported between the lower positions of the support frame 5.5 via a bracket 12.12. The endless belt 13 is wound around the upper surface of the feed roller 7.8.9 so as to come into contact with the upper surfaces of the belt pulley (not shown) and the return side roller 11.

The thus-constructed one has the same function as the conventional one that carries the foundry sand S on the endless belt 13, and only a part of the foundry sand adhered to the surface of the endless belt 13 is transferred. The S rotates around the return side and comes into contact with the return side roller 11 and spills off, and is accumulated on the sand receiving plate / frame 3 forming a flat surface. Therefore, the foundry sand S spilled and stored is easily recovered by a scoop or the like.

[0008]

[Effect of device]

 As is apparent from the above description, the present invention has a basic part of the belt conveyor formed by bending a steel material into a flat rectangular upper surface that also serves as a sand receiving plate. It is remarkable that it is simple and has the effect of facilitating the recovery of spilled sand.
