Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and more specifically to a stone conveying device. Background Technology

[0002] Stone conveyors are a common type of transport machine, mainly used for conveying bulk materials or packaged goods. They are suitable for industries such as mining, metallurgy, building materials, and chemicals. The machine body is constructed from high-quality steel plates into an inclined frame, equipped with conveyor belts, rollers, and other transmission devices. It is driven by a geared motor or electric drum and features simple structure, convenient maintenance, and strong component versatility.

[0003] However, during the stone transport process, it may contain magnetically attracted metal waste such as iron. The existing method requires multiple sorting before stone transport (crushed stone transport). For example, most of the metal waste is sorted out when large stones are crushed. However, it is still possible that a small amount of magnetically attracted metal waste such as iron will still be mixed in the crushed stone. Metal waste can be recycled and reused. It would be wasteful to use it directly as stone for subsequent pouring and other purposes. Utility Model Content

[0029] Furthermore, the upper lateral moving mechanism 30 includes front and rear fixed plates 34 fixed at the middle and right sides of the top plate of the upper support frame 20. The two ends of the connecting shaft 35 extending forward and backward are movably connected to the corresponding two fixed plates 34 through bearings. A sprocket 36 is fixed in the middle of the connecting shaft 35, and a chain 37 is tensioned on the two sprockets 36. A movable reduction motor 38 (which is a reduction motor) is fixed on the outer wall of one of the fixed plates 34. The output shaft of the movable reduction motor 38 is a splined shaft that is inserted into the splined hole at one end of the corresponding connecting shaft 35 and drives the connecting shaft 35 to rotate.

[0030] A movable block 31 is fixed to the lower part of the chain 37.

[0031] Furthermore, the upper support frame 20 includes a top plate, and the bottom surface of the top plate is fixed with downwardly extending support plates 29 on the left and right sides. The bottom surface of the support plates 29 is fixed to the top surface of the two side support frames. A material passage groove is formed in the middle of the bottom surface of the support plate 29, and the material passage groove faces the top surface of the belt conveyor 12.

[0032] The top plate is provided with a lower intermediate support plate 25 at the lower center. The bottom surface of the lower intermediate support plate 25 is fixed to the top surface of the two side support frames. A second material passage groove is formed in the middle of the bottom surface of the lower intermediate support plate 25, which faces the top surface of the belt conveyor 12.

[0033] The transverse guide rod 2 is fixed in the middle of the lower middle support plate 25 and the right support plate. The bottom right side of the receiving trough 40 is fixed with a guide support block 41. The transverse guide rod 2 is inserted into the left and right extended guide through hole formed in the middle of the guide support block 41.

[0034] Furthermore, an elastic limiting block 26 is fixed on the right side wall of the middle part of the support plate 29 on the left side, and the left end of the receiving trough 40 faces the elastic limiting block 26 to prevent the left end of the receiving trough 40 from hitting the support plate 29 on the left side.

[0035] The receiving trough 40 includes a bottom plate. The left end of the bottom plate is an inclined part that extends upward and to the left, and the right part of the bottom is a horizontal part. The front and rear parts of the top surface of the bottom plate are fixed or formed with side baffles. The top surface of the right end of the horizontal part is formed with an upward extending baffle plate part 42. The side baffle of the rear part of the bottom plate is formed with a discharge through hole 43 facing the horizontal part. The rear end of the horizontal part is formed with a discharge plate 44 that extends downward and backward. The left and right sides of the discharge plate 44 are formed or fixed with rear side baffles. The front end of the rear side baffle on the left side is fixed to the rear wall of the rear side baffle, and the front end of the rear side baffle on the right side is fixed to the rear wall of the baffle plate part 42.

[0036] The rear end of the feed plate 44 extends out from the rear side of the main frame 10.

[0037] In this embodiment, the stone (crushed stone) is poured into the upper right side of the belt body of the conveyor belt 12. The reduction motor 13 drives the stone to the left and upward. At this time, the push rod of the electric push rod 21 is in the extended state. Simultaneously, the electromagnet plate 23 is activated and approaches the stone conveyed on the conveyor belt 12. This allows it to attract any magnetically attracted metal waste mixed in with the stone. However, the electromagnet plate 23 cannot attract any metal substances mixed inside the stone. Of course, the stone being conveyed at this time is crushed stone, which is generally composed of small particles and usually does not contain much metal.

[0038] Then, after running for a certain period of time, the push rod of the electric push rod 21 retracts, raising the electromagnet plate 23. Then, the moving reduction motor 38 runs, moving the receiving trough 40 to the left and placing it directly below the electromagnet plate 23 (the receiving trough 40 is made of nylon or other plastic material, which will not be attracted by the electromagnet plate 23). Then, the power to the electromagnet plate 23 is turned off, and the material it has attracted will fall into the receiving trough 40. Finally, it is discharged from the rear end of the discharge plate 44, where a receiving bucket can be placed below the rear end to receive this batch of material. It is very convenient and has a good effect.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
