Description

Technical Field

[0001] The present application relates to the field of sand making, and in particular to an adjustable slag sand making device. Background Art

[0002] Tunnel slag is the stone waste excavated during tunnel excavation. The surrounding rock of some tunnels is good, and the excavated tunnel slag has high strength and has the potential to be used as machine-made sand and gravel.

[0003] Since slag is a product of the excavation process, its size and shape are different. In order to make the recycling and reuse of slag more convenient, it is necessary to put the slag raw materials of different sizes and shapes into the sand making machine, which will crush them so that the slag becomes small and uniform.

[0004] Commonly used sand making machines mostly use a double-roller crushing method, which uses two rollers rotating in opposite directions to crush large pieces of slag raw materials for subsequent use. When the sand making roller crushes the material, it sometimes encounters hard and large materials. Therefore, one of the sand making rollers of the existing sand making machine has a spring structure, which can retreat as a whole when encountering hard and large stones, so that the large stones can fall smoothly and avoid damage to the sand making roller due to excessive pressure. However, this method will result in that when letting the large stones fall, the distance between the two sand making rollers is large at this time, so the materials at this time fall without being squeezed, which will result in no sand making effect in this short period of time, resulting in a decrease in the quality of sand making, and mixing in materials that have not been squeezed by the sand making rollers. Summary of the invention

[0005] Purpose of the invention: In order to solve the problems existing in the prior art, the present application proposes an adjustable slag sand making device.

[0006] Technical solution: An adjustable slag sand making device, comprising a control unit, a base, a sand making box, a first sand making roller unit and a second sand making roller unit, wherein the sand making box has a feed port on the top and a discharge port on the bottom; the first sand making roller unit comprises a first rotating shaft installed on the sand making box, a first roller installed on the first rotating shaft, a first roller skin installed on the first rotating roller, a first passive wheel installed on the first rotating shaft, a first motor installed on the base, a first driving wheel installed on the first motor, and a first synchronous belt connecting the first driving wheel and the first passive wheel; the second sand making roller unit comprises a second rotating shaft, a second roller installed on the second rotating shaft, a second passive wheel installed on the second rotating shaft, a second motor installed on the base, a second driving wheel installed on the second motor, and a second synchronous belt connecting the second driving wheel and the second passive wheel, a plurality of sub-rotating units are installed in parallel at the second roller along the axial direction of the second rotating shaft, and the sub-rotating unit comprises a mounting ring fixedly connected to the second roller and a second roller skin connected to the mounting ring through a plurality of supporting springs.

[0007] Therefore, when encountering larger stones, multiple independent second rollers can retreat independently, so when avoiding stones at one position, the remaining rollers can still play a sand-making effect.

[0008] Furthermore, the outer circumferential surface of the mounting ring has a plurality of outer protrusions distributed in a ring shape with equal spacing, and the inner circumferential surface of the second roller skin has a plurality of inner protrusions distributed in a ring shape with equal spacing, the number of the outer protrusions and the inner protrusions are equal and the two correspond one to one, and the supporting springs are connected between the corresponding outer protrusions and the inner protrusions; both sides of the second roller skin have circular side baffles.

[0009] Thereby, the inner space between adjacent roller skins is not exposed, and the slag is prevented from falling into the roller skin, thereby ensuring the normal operation of the roller skin.

[0010] Furthermore, an adjusting seat, a limiting slide rail and a third motor are installed on the base, and the third motor drives a first screw rod. The adjusting seat has a limiting slide groove that cooperates with the limiting slide rail and a threaded channel that cooperates with the first screw rod; both sides of the sand making box have side through holes, and the side through holes have a strip slide rail, and a slide seat is installed on the side through holes, and the slide seat has a strip slide groove that cooperates with the strip slide rail; the slide seat is also connected to a side convex plate, and the second rotating shaft is installed between the two slide seats, and a hydraulic telescopic rod is connected between each side convex plate and the adjusting seat; a tensioning unit is also installed on the base, and the tensioning unit includes a fixed frame, a tensioning wheel mounting frame and a tensioning wheel, and a tensioning spring is connected between the fixed frame and the tensioning wheel mounting frame, and the second synchronous belt passes through the tensioning wheel.

[0011] Therefore, the distance between the sand making rollers can be adjusted according to different situations, which is convenient for subsequent maintenance and use. And the distance between the two sand making rollers during work can be adjusted to achieve different sand making levels.

[0012] And when making sand at different levels, since the third motor will drive the adjustment seat to move a very small distance (this distance is very small), the tensioning wheel can help adapt to this very small distance, so as to better drive the second rotating shaft.

[0013] Furthermore, a mounting plate is installed in the sand making box, the mounting plate has a horizontal slide rail, a fourth motor, a screw bearing and a limit plate are installed on the mounting plate, a second screw is connected between the fourth motor and the screw bearing, the limit plate has a horizontal slide groove that cooperates with the horizontal slide rail and a threaded hole that cooperates with the second screw, a guide roller frame is installed on the limit plate, and two abutting guide rollers are installed on the guide roller frame; a slide rail frame is provided on the top of the sand making box, a fan unit is installed on the slide rail frame, a handle is provided on the top of the fan unit, and the fan unit and the slide rail frame can be fixed by a locking bolt.

[0014] This makes it easier to clean the roller surface and avoids gravel being mixed between adjacent rollers.

[0015] Furthermore, two connecting cross bars are installed between the two slides, and the connecting cross bars have multiple installation positions, the number of the installation positions is equal to the number of the second roller skins and the positions correspond one to one, each installation position is installed with a limit rod, and the top and bottom ends of the limit plate have limit holes that cooperate with the limit rod.

[0016] Thereby, the tightness and firmness between the various components can be achieved during the cleaning process.

[0017] Furthermore, each installation position is provided with two limiting plug rods, and the top end and the bottom end of the limiting plate are provided with two limiting plug holes.

[0018] Therefore, the cooperation between a limiting plug rod and a plurality of limiting plug holes makes the overall structure more stable.

[0019] Furthermore, the base includes a top plate, a bottom plate and two supporting vertical plates, the supporting vertical plates are provided with a plurality of reinforcing ribs, both ends of the base are open, and the top plate of the base is provided with a feeding through hole connected to the feeding port.

[0020] Furthermore, side shields for partially shielding the side through holes are installed on both sides of the sand making box.

[0021] Thereby, the side through holes are shielded to a certain extent to prevent foreign matter from entering the sand making box.

[0022] Furthermore, the mounting plate is connected to the sand making box through a plurality of I-shaped connectors.

[0023] Furthermore, a first bearing is installed between the first rotating shaft and the sand making box, and a second bearing is installed between the second rotating shaft and the slide seat; the slag sand making device can be in a sand making state and a cleaning state, in which the hydraulic telescopic rod is in its longest state, and the fan unit is not located above the feed port; in the cleaning state, the hydraulic telescopic rod is in its shortest state, all the limit plug holes are inserted by the limit plug rod corresponding to one of the second roller skins, two abutting guide rollers abut against the second roller skin and make the second roller skin closer to the first rotating shaft than other second roller skins, and the fan unit is located above the feed port.

[0024] Thus, the sand making state can achieve sand making, and the cleaning state can achieve better cleaning.

[0025] Beneficial effects: The adjustable slag sand making device of the present application has the following advantages over the prior art:

[0026] 1) When encountering larger slag, multiple independent second rollers can retreat independently, while avoiding larger stones, the remaining rollers can still play the role of sand making.

[0027] 2) The distance of the adjusting seat can be adjusted by the control of the screw rod, so that the distance between the first and second roller skins can be adjusted to meet the requirements of different levels of sand making, thereby achieving the effect of adjustable sand making.

[0028] 3) Through the setting of the hydraulic telescopic rod, the sand making device can be adjusted to the sand making state and the maintenance state, so as to facilitate the cleaning and maintenance of the sand making device.

[0029] 4) The surface of the roller skin can be cleaned in time through the fan unit and the abutting guide roller, thereby realizing automatic cleaning and avoiding gravel between adjacent roller skins. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Two connecting cross bars 2.3.1.2 are installed between the two slides 2.3.1. The connecting cross bars 2.3.1.2 have multiple installation positions. The number of the installation positions is equal to the number of the second roller skins 4.2.3 and the positions correspond one to one. Each installation position is installed with a limit rod 2.3.1.3. The top and bottom ends of the limit plate 2.4.4 have limit holes that cooperate with the limit rod 2.3.1.3. Each installation position has two limit rods 2.3.1.3. The top and bottom ends of the limit plate 2.4.4 have two limit holes.

The mounting plate 2.3 is connected to the sand making box 2 through a plurality of I-shaped connectors 2.7.

[0048] A first bearing is installed between the first rotating shaft 3.1 and the sand making box 2, and a second bearing is installed between the second rotating shaft 4.1 and the slide seat 2.3.1; the slag sand making device can be in a sand making state and a cleaning state. In the sand making state, the hydraulic telescopic rod 5 is in its longest state, and the fan unit is not located above the feed port 2.1; in the cleaning state, the hydraulic telescopic rod 5 is in its shortest state, all the limit plug holes are inserted by the limit plug rod 2.3.1.3 corresponding to one of the second roller skins 4.2.3, two abutting guide rollers 2.4.4.2 abut against the second roller skin 4.2.3 and make the second roller skin 4.2.3 closer to the first rotating shaft 3.1 than other second roller skins 4.2.3, and the fan unit is located above the feed port 2.1.

[0049] Working principle: In the sand making state, first install the second synchronous belt 4.6 between the second passive wheel 4.3 and the second driving wheel 4.5, then start the whole device through the control unit to operate, and then pour the slag into the sand making machine from the feed port 2.1, and then the slag is squeezed and crushed by the first sand making roller unit 3 and the second sand making roller unit 4, so as to obtain slag sand and gravel with uniform shape and size, and due to different engineering requirements, the required slag size is also different, so the third motor 1.3 drives the first screw rod 1.3.1 to make the adjustment seat 1.1 able to move on the limit slide rail 1.2, thereby changing the distance between the first sand making unit 3 and the second sand making unit 4, so as to produce slag of different specifications that meet the requirements. And because the second sand-making roller unit has multiple independent sub-rotating units, when a sub-rotating unit encounters a larger stone, the spring of the sub-rotating unit will be compressed, so that the second roller skin will move backward to avoid the stone and prevent damage to the roller skin due to excessive pressure. However, at this time, the other sub-rotating units are not over-squeezed and can still perform sand-making work normally.

[0050] After working for a period of time, since the second sand-making roller unit of the present application has multiple sub-rotation units, although there are circular side baffles on both sides of the second roller skin, as the use time goes by, gravel may still be sandwiched between adjacent second roller skins. If it is not cleaned in time, it will affect the subsequent sand-making work. Therefore, the sand-making device of the present application needs to be cleaned regularly. In the cleaning state, first remove the second synchronous belt 4.6, move the fan unit, and lock it so that the fan unit is just above the feed port 2.1. The fourth motor drives the limit plate so that the limit plate is aligned with a sub-rotation unit at the end. Then, shorten the hydraulic telescopic rod to the shortest, and replace the second synchronous belt with a new specification (at this time, since the distance between the second driving wheel and the second passive wheel becomes larger, the replaced second synchronous belt is longer than the previous second synchronous belt). Figure 5 As shown, the abutting guide roller abuts against the second roller skin of the sub-rotating unit. Under the drive of the second motor, the second roller skin of the sub-rotating unit rotates and causes the abutting guide roller to abut against it, generating Figure 5 The protrusion toward the first rotating shaft exposes the space between two adjacent second roller skins, and the broken stones can be cleaned up under the action of the airflow of the fan.

[0051] After the cleaning is completed, the hydraulic telescopic rod is shortened so that the fourth motor can drive the limit plate to move and align with the next sub-rotation unit, thereby repeating the above cleaning process until all the sub-rotation units are cleaned.

[0052] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
