Description

Technical Field

[0001] This utility model belongs to the field of mining sand and gravel transfer technology, specifically relating to a green mine intelligent sand and gravel transfer device. Background Technology

[0002] Sand and gravel refer to a loose mixture of sand and gravel. In geology, mineral or rock particles with a diameter of 0.074–2 mm are called sand. In actual mining operations, transport trucks are used to transport and process the sand and gravel discharged from mining.

[0003] In actual use, existing transport trucks often cause dust spillage and gravel to fall on the ground due to the ruggedness of the transport roads and the mixing of dust with airflow during high-speed transport. This not only affects the transport environment and nearby vehicles, but the scattered gravel may also damage the road surface when combined with the crushing of vehicles. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a green intelligent sand and gravel transfer device for mining. It aims to solve the problem that in the existing technology, due to the ruggedness of the transportation road and the mixing of sand and gravel with airflow during high-speed transportation, dust overflows and sand and gravel are scattered on the ground along the way. This not only affects the transportation environment and nearby vehicles, but the scattered sand and gravel may also damage the road surface when combined with the crushing of vehicles.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a green mine intelligent waste disposal and sand and gravel transfer device, comprising a transport bin, a bin door installed at the front end of the transport bin, and dust suppression and anti-spillage mechanisms jointly installed on both sides and the top of the transport bin. The dust suppression and anti-spillage mechanism includes a side mounting frame, a screw sliding sleeve, and a forward moving frame, and a cleaning mechanism is installed on the inner side of the screw sliding sleeve. The side mounting frames are respectively located on both sides of the transport bin, and a displacement component is installed in the middle of the side mounting frames. An inner mounting frame is fixed on one side of the top of the transport bin, and a dust cover is installed in the middle of the inner mounting frame.

[0008] Furthermore, the displacement component includes a drive motor, which is mounted on one end of one of the side mounts. The output end of the drive motor is connected to a lead screw, and a lead screw sleeve is screwed around one side of the lead screw. A guide frame is fixed on one side of the lead screw sleeve, and a forward moving frame is connected above the guide frame.

[0009] Furthermore, the guide frame and the side mounting frame are movably connected, and a movable rod for guiding the forward moving frame is fixed in the middle of one of the side mounting frames.

[0010] Furthermore, the two ends of the dust cover are fixedly connected to the inner frame and the front moving frame, respectively.

[0011] Furthermore, the cleaning mechanism includes a mounting frame, which is fixed to one side of the lead screw sleeve. The inner ends of the mounting frame are provided with jet splitters on both sides, and jet heads are provided on the inner sides of the jet splitters.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model's transport compartment is installed in the placement area of ​​transport trucks for transporting sand and gravel. After the sand and gravel are all piled up and placed in the transport compartment using an excavator or other means, personnel can start the drive motor to rotate the transmission screw. At this time, the screw sleeve interacting with the screw will, along with the guide frame and the forward moving frame, pull one end of the dust cover to move in coordination with the guide rod in the middle of one of the side loading frames. The dust cover is initially folded and stacked inside the inner loading frame. After being pulled, it can be laid out as a square cover on top of the transport compartment. This not only prevents the sand and gravel from spilling out during transportation but also achieves a good dust leakage effect.

[0016] To reduce the impact of dust adhesion on the transmission lead screw under environmental factors, this invention allows personnel to activate the air compressor carried by the transport truck each time the drive motor starts. At this time, the air compressor reduces the volume of air and increases the pressure through mechanical compression, thereby generating compressed air. The compressed air is stored in an air tank and, with the protection of pressure reducing valves, pressure gauges, and flow regulating valves, supplies a stable pressure and flow to the two interconnected jet nozzles at the front end of the jet nozzle splitter via telescopic air pipes and split air pipes. Since the cleaning mechanism is located inside the lead screw sleeve, the two sets of jet nozzles can move laterally with the lead screw sleeve. Regardless of the direction in which the lead screw sleeve moves, the jet nozzles in that direction can uniformly spray and clean the transmission lead screw in that direction, thereby significantly reducing dust adhesion.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This specific embodiment is a green mine intelligent waste disposal and sand and gravel transfer device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the system includes a transport compartment 1, with a door 2 installed at the front end. Dust suppression and spill prevention mechanisms 3 are jointly installed on both sides and above the transport compartment 1. The dust suppression and spill prevention mechanism 3 includes a side mounting frame 31, a screw sleeve 323, and a forward moving frame 325. A cleaning mechanism 4 is installed inside the screw sleeve 323. The side mounting frames 31 are located on both sides of the transport compartment 1, and a displacement component 32 is installed in the middle of each side mounting frame 31. The displacement component 32 includes a drive motor 321, which is mounted at one end of one of the side mounting frames 31. The output end of the drive motor 321 is connected to a transmission screw 322. A screw sleeve 323 is screwed around one side of the transmission screw 322. A guide frame 324 is fixed to one side of the screw sleeve 323, and a forward moving frame 325 is connected above the guide frame 324. The guide frame 324 and the side mounting frames 31 are movably connected. A forward moving frame 325 is fixed in the middle of one of the side mounting frames 31. The movable rod of the moving frame 325 guides the inner loading frame 33, which is fixedly installed on one side of the upper part of the transport compartment 1. The inner loading frame 33 is equipped with a dust cover 34 in the middle. The two ends of the dust cover 34 are fixedly connected to the inner loading frame 33 and the front moving frame 325 respectively. The transport compartment 1 is installed in the placement area of ​​the transport truck for transporting sand and gravel. After the sand and gravel are piled up in the transport compartment 1 by excavators, etc., the personnel can start the drive motor 321 to rotate the transmission screw 322. At this time, the screw sleeve 323, which interacts with the screw, will carry the guide frame 324 and the front moving frame 325 to pull one end of the dust cover 34 to move in coordination with the movable rod in the middle of one of the side loading frames 31. The dust cover 34 is initially folded and stacked inside the inner loading frame 33. After being pulled, it can be laid on the top of the transport compartment 1 in a square cover shape. This can prevent the sand and gravel from spilling out during transportation and also achieve a good dust leakage effect.

[0025] The cleaning mechanism 4 includes a mounting frame 41, which is fixed to one side of the lead screw sleeve 323. Air jet splitters 42 are provided on both sides of the inner end of the mounting frame 41, and air jet heads 43 are provided on the inner side of each air jet splitter 42. A split air pipe 44 is connected to the inner side of each air jet splitter 42, and a telescopic air pipe 45 is connected to the end of each split air pipe 44. The air jet splitters 42 and air jet heads 43 are symmetrically arranged along the vertical central axis of the mounting frame 41. To reduce the impact of dust adhesion on the transmission lead screw 322 under environmental factors, personnel can turn on the air compressor carried by the transport truck each time the drive motor 321 is started. At this time, the air compressor mechanically compresses... The compressed air is generated by reducing the volume of air and increasing the pressure. The compressed air is stored in the air tank and supplied to the two jet nozzles 43 connected at the front end of the jet splitter 42 with stable pressure and flow through the telescopic air pipe 45 and the split air pipe 44, with the pressure and flow of the pressure reducing valve, pressure gauge and flow regulating valve. Since the cleaning mechanism 4 is located inside the lead screw sleeve 323, the two sets of jet nozzles 43 can move laterally with the lead screw sleeve 323. No matter which direction the lead screw sleeve 323 moves, the jet nozzles 43 in that direction can uniformly spray and clean the transmission lead screw 322 in that direction, thereby greatly reducing dust adhesion.

[0026] Working Principle: The transport bin 1 is installed in the parking area of ​​transport trucks for transporting sand and gravel. After the sand and gravel are completely piled into the transport bin 1 using excavators or other equipment, personnel can start the drive motor 321 to rotate the transmission screw 322. At this time, the screw sleeve 323, which interacts with the screw, will pull one end of the dust cover 34 with the guide frame 324 and the forward moving frame 325, in conjunction with the guide rod in the middle of one of the side loading frames 31. The dust cover 34 is initially folded and stacked inside the inner loading frame 33. After being pulled, it can be laid on top of the transport bin 1 in a square cover shape. This not only prevents the sand and gravel from spilling out during transportation but also achieves a good dust leakage effect. Finally, in order to reduce the impact of dust adhesion on the transmission screw 322 under environmental factors, personnel can... During the start-up process of drive motor 321, the air compressor carried by the transport truck is turned on. At this time, the air compressor reduces the volume of air and increases the pressure through mechanical compression, thereby generating compressed air. The compressed air is stored in the air tank. With the protection of pressure reducing valve, pressure gauge and flow regulating valve, the air is supplied to the two air nozzles 43 connected at the front end of the air jet splitter 42 with stable pressure and flow through the telescopic air pipe 45 and the split air pipe 44. Since the cleaning mechanism 4 is located inside the lead screw sleeve 323, the two sets of air nozzles 43 can move laterally with the lead screw sleeve 323. No matter which direction the lead screw sleeve 323 moves, the air nozzles 43 in that direction can uniformly spray and clean the transmission lead screw 322 in that direction, thereby greatly reducing dust adhesion.
