Description

Technical Field

[0001] This utility model relates to the field of crushers, and in particular to an adjustable gradation crusher. Background Technology

[0002] Crusheres are widely used in many fields such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemicals. With the standardization of the building materials aggregate market at present, the aggregates produced by conventional crushing equipment can no longer meet the requirements of the current aggregate market. Furthermore, the crushing effect of the original crushing equipment is relatively simple, and the selected equipment can only achieve a very small crushing ratio. Moreover, the output material needs to be sorted separately before it can be used.

[0003] To meet market demands, multiple machines are needed to form a production line, posing a significant challenge to overall planning in terms of land area, environment, and procurement costs. Therefore, a comprehensive device is needed that can achieve a large crushing ratio and continuous gradation of crushed materials. This device should integrate crushing and sand making, allowing for selective and adjustable output after large materials are fed into the equipment, crushing the material into the desired gradation in one step. This is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In order to solve the problems existing in the background art, this utility model proposes an adjustable gradation crusher.

[0005] An adjustable gradation crusher includes a frame, a cylinder fixing frame fixedly installed on the top of the frame, a rotating cylinder rotatably connected inside the cylinder fixing frame, an array of lining components inside the rotating cylinder, a main shaft located at the center of the rotating cylinder, and crushing components arranged on the surface of the main shaft; a second drive motor is located at the top right end of the frame, the right end of the main shaft is connected to the second drive motor via a coupling, and a feed hopper is inserted into the upper left end of the rotating cylinder.

[0006] Based on the above, the number of the inner lining components is three, forming crushing chamber one, crushing chamber two and crushing chamber three from left to right inside the rotating drum. The right end of crushing chamber one, crushing chamber two and crushing chamber three are all provided with a discharge port. Three discharge hoppers are arrayed on the frame, and the three discharge hoppers are respectively located directly below the three discharge ports.

[0007] Based on the above, both ends of the rotating drum are fixed with annular end caps by bolts. The annular end caps have a first insertion hole arrayed on one side facing the end of the rotating drum. The rotating drum surface has three sets of discharge arc grooves arrayed along its length. Two reinforcing rings are fixedly installed on the outer wall of the rotating drum. Two drag wheels are attached to the lower surface of each reinforcing ring. A first drive motor is connected to the center of each drag wheel.

[0008] Based on the above, the inner lining assembly includes an inner tube, with inserted posts fixed in an array at both ends of the inner tube. Spiral lifting plates are welded in an array on the inner wall of the inner tube. A partition is provided between two adjacent inner tubes. A second insertion hole is arrayed through the surface of the partition. The inserted posts are inserted into the second insertion hole or the first insertion hole. A screen hole is arrayed through the circumferential surface of the right end of the inner tube. The screen hole is connected to the discharge arc groove. The diameter of the screen hole on the three sets of inner tubes gradually decreases from left to right.

[0009] Based on the above, the spiral lifting plates inside the three sets of inner cylinders have the same spiral direction, and the inner diameter of the partition is equal to the inner diameter of the inner cylinder.

[0010] Based on the above, the spiral lifting plates inside the two sets of inner cylinders on the left are clockwise, and the spiral lifting plates inside the inner cylinder on the far right are counterclockwise. The inner diameter of the second insertion hole on the left is equal to the inner diameter of the inner cylinder, and the inner diameter of the partition on the right is smaller than the inner diameter of the inner cylinder.

[0011] Based on the above, the spiral lifting blade inside the leftmost inner cylinder has a right-hand spiral direction, while the spiral lifting blades inside the two sets of inner cylinders on the right have a left-hand spiral direction, and the inner diameter of the two second insertion holes is smaller than the inner diameter of the inner cylinder.

[0012] Based on the above, multiple hammer discs are fixedly installed on the surface of the main shaft inside the rotating drum. From left to right, the radii of the multiple hammer discs gradually increase. Hammer heads are arranged in an array and hinged on the circumferential surface of the hammer discs. Two fixed bearing seats are fixedly installed on the top of the frame, and the main shaft is rotatably connected through the two fixed bearing seats.

[0013] This utility model has substantial features and progress compared to the prior art. Specifically, by adjusting the spiral direction of the spiral lifting plates inside the three sets of inner cylinders and adjusting the blocking position of the partition in crushing chamber one, crushing chamber two and crushing chamber three, this utility model can process finished products with different particle sizes. It has the advantages of easy adjustment of gradation and processing finished products with different particle sizes. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figures 1-7 As shown, an adjustable gradation crusher includes a frame 100, a cylinder fixing frame 200 fixedly mounted on the top of the frame 100, a rotating drum 300 rotatably connected inside the cylinder fixing frame 200, an array of inner lining components 400 arranged inside the rotating drum 300, a main shaft 500 located at the center of the rotating drum 300, and crushing components arranged on the surface of the main shaft 500; a second drive motor 600 is located at the top right end of the frame 100, and the right end of the main shaft 500 is connected to the second drive motor 600 via a coupling 700; the second drive motor 600 is model Y315L2-2. A feed hopper 800 is inserted into the upper left part of the rotating drum 300.

[0024] In use, there are three liner components 400, which form crushing chamber one, crushing chamber two, and crushing chamber three from left to right inside the rotating drum 300. Each of the three crushing chambers has a discharge port at its right end. Three discharge hoppers 900 are arrayed on the frame 100, located directly below the three discharge ports. Thus, the material discharged from the three discharge ports is transferred out through the three discharge hoppers 900. In practice, both ends of the rotating drum 300 are fixed with annular end caps 301 by bolts. The annular end caps 301 have first insertion holes 302 arranged in an array on one side facing the end of the rotating drum 300. Three sets of discharge arc grooves 303 are arranged in an array along the length of the rotating drum 300. Two reinforcing rings 304 are fixedly installed on the outer wall of the rotating drum 300. Two drag wheels 305 are attached to the lower surface of each reinforcing ring 304. A first drive motor (not shown in the figure, but referencing prior art) is connected to the center of each drag wheel 305. The first drive motor drives the drag wheels 305 to rotate, thereby driving the reinforcing rings 304 and the rotating drum 300 to rotate.

[0025] Multiple hammer discs 501 are fixedly mounted on the surface of the main shaft 500 inside the rotating drum 300. From left to right, the radii of the hammer discs 501 gradually increase. Hammer heads 502 are hinged in an array on the circumferential surface of the hammer discs 501. The hammer discs 501 and hammer heads 502 constitute a crushing assembly. Two fixed bearing seats 503 are fixedly mounted on the top of the frame 100, and the main shaft 500 is rotatably connected to the two fixed bearing seats 503 through it. As a result, the distance between the multiple hammer heads 502 and the inner wall of the liner assembly 400 gradually decreases from left to right, thus gradually reducing the particle size of the crushed material.

[0026] Specifically, the inner lining assembly 400 includes an inner cylinder 401, with insert posts 402 fixed in an array at both ends. Spiral lifting blades 403 are welded in an array to the inner wall of the inner cylinder 401. A partition plate 404 is provided between adjacent inner cylinders 401, and a second insertion hole 405 is arrayed through the surface of the partition plate 404. The insert posts 402 are inserted into the second insertion hole 405 or the first insertion hole 302, thereby stably inserting the inner lining assembly 400 into the interior of the rotating drum 300. When the rotating drum 300 rotates, it drives the inner cylinder 401 to rotate synchronously. A screen hole 406 is arrayed through the circumference of the right end of the inner cylinder 401, communicating with the discharge arc groove 303. The diameter of the screen holes 406 on the three sets of inner cylinders 401 gradually decreases from left to right. The screen holes 406 are used to screen the crushed material. The screen hole 406 and the discharge arc groove 303 form a discharge port. The crushed material passes through the screen hole 406 and the discharge arc groove 303 and enters the interior of the discharge hopper 900.

[0027] During operation, in Example 1: the second drive motor 600 drives the main shaft 500 and the hammer disc 501 on the main shaft 500 to rotate through the coupling 700. The rotation of the hammer disc 501 simultaneously drives the hammer head 502 hinged on the hammer disc 501 to perform centrifugal motion. Since the diameter of the hammer disc 501 fixed on the main shaft 501 is different, the hammering force of the hammer head 502 on the material on the different hammer discs 501 is also different.

[0028] Inside the crushing chamber: When the material enters the crushing chamber from the feed hopper 800, because the feed size is relatively large, the first-stage hammer disc 501 at this position is relatively small, allowing space for the material to enter the crushing chamber. Furthermore, the hammers 502 that first come into contact with the material, under the action of centrifugal force, first crush the large pieces of material into uniform small pieces before proceeding to the next crushing stage.

[0029] After being hammered by three or more levels of crushing hammers 502 in the first crushing chamber, the material that meets the requirements of the second crushing chamber enters the second crushing chamber through the space between the hammer disc 501 and the partition 404. The material that does not meet the requirements is driven by the towing wheel 305 to rotate the drum 300 and makes circular motion in the space formed by the adjustable curvature spiral lifting plate 403 and the inner cylinder 401. The material that does not meet the requirements at the top position enters the hammer disc 501 in the first crushing chamber by gravity and continues to be crushed.

[0030] Inside the second crushing chamber: Qualified materials that have been crushed in the first crushing chamber enter the second crushing chamber. Due to inertia and the action of the adjustable curvature spiral lifting plate 403, the materials are classified into three grades. Large pieces of material are crushed sequentially through the first row of hammer discs 501, the second row of hammer discs 501, the third row of hammer discs 501, and so on. Medium-sized materials are crushed sequentially through the second row of hammer discs 501, the third row of hammer discs 501, and so on. Small pieces of material are crushed sequentially through the third row of hammer discs 501, the fourth row of hammer discs 501, and so on.

[0031] Materials that meet the requirements for entering the third space of the crushing chamber enter the third space of the crushing chamber through the gap between the partition 404 and the first row of hammer discs 501 in the third crushing chamber. Materials that do not meet the requirements are lifted up by the adjustable curvature spiral lifting plate 403 and continue to be crushed in the second space of the crushing chamber.

[0032] Inside the third crushing chamber: After being crushed in the first and second crushing chambers, the qualified material is distributed circumferentially inside the inner cylinder 401 by the adjustable curvature spiral lifting plate 403. The qualified finished product is discharged from the third crushing chamber through the discharge arc groove 303 distributed circumferentially by the rotating drum 300. The unqualified finished product is lifted by the adjustable curvature spiral lifting plate 403 and enters the crushing zone of the hammer disc 501 and hammer head 502 in the third crushing chamber for crushing, and is crushed into qualified finished products in sequence.

[0033] In this embodiment, the spiral lifting plates 403 inside the three sets of inner cylinders 401 have the same spiral direction, and the inner diameter of the partition plate 404 is equal to the inner diameter of the inner cylinder 401.

[0034] Example 2: If the finished material with the particle size required by crushing chamber two is needed, the partition 404 between crushing chamber two and crushing chamber three should be replaced. The spiral direction of the spiral lifting blades 403 inside the two sets of inner cylinders 401 on the left is right-handed, and the spiral direction of the spiral lifting blades 403 inside the rightmost inner cylinder 401 is left-handed;

[0035] By completely separating crushing chamber two and crushing chamber three, continuously graded medium-grade finished materials can be produced. The inner diameter of the second insertion hole 405 on the left is equal to the inner diameter of the inner cylinder 401, while the inner diameter of the partition plate 404 on the right is smaller than that of the inner cylinder 401. At this time, the material in crushing chamber three moves from the right end to the left end. The fine finished material in crushing chamber three enters crushing chamber two, realizing the adjustment of the gradation of medium-grade finished materials. At this time, the outside of the rotating drum 300 of crushing chamber three is sealed to prevent material from being discharged from the rotating drum 300 of crushing chamber three. The discharge arc groove 303 of the rotating drum 300 of crushing chamber two is opened, and the medium-grade finished material is discharged through the discharge hopper 900 and conveyed to the medium-grade finished product bin.

[0036] Example 3: If a finished product with the particle size of crushing chamber one is required, the partition 404 between crushing chamber one and crushing chamber two is replaced. The spiral direction of the spiral lifting plate 403 inside the leftmost inner cylinder 401 is right-handed, and the spiral direction of the spiral lifting plate 403 inside the two sets of inner cylinders 401 on the right is left-handed. The inner diameter of the two second insertion holes 405 is smaller than the inner diameter of the inner cylinder 401. By completely separating crushing chamber one and crushing chamber two, a continuously graded large-sized finished product can be produced. At this time, the material in crushing chamber two moves from the right end to the left end. At this time, the fine finished product material in crushing chamber two enters crushing chamber one, realizing the adjustment of the gradation of the large-sized finished product. At this time, the outside of the inner cylinder 401 of crushing chamber two is sealed to prevent the material from being discharged from the inner cylinder 401 of crushing chamber two. The discharge arc groove 303 of the rotating drum 300 of crushing chamber one is opened, and the medium-sized finished product is discharged through the discharge hopper 900 and transported to the large-sized finished product bin.

[0037] Additionally, when production reaches the designated cycle and one side of the hammer 502 is worn, and the output drops to a certain level, the second drive motor 600 is reversed. This allows the unworn side of the hammer 502 to contact the material for crushing, which can increase production capacity to some extent. At this time, the drum 300 also rotates under the reverse action of the roller 305, and the adjustable curvature spiral lifting plate 403 delivers the material to the vicinity of the hammer 502 for further crushing. Since the crushing energy is relatively high at this stage, the material needs to be re-tested. If the particle size distribution is too small, the speed of the roller 305 needs to be adjusted to reduce the number of hammer blows and increase the particle size distribution. If the particle size distribution is too large, the speed of the roller 305 needs to be adjusted to increase the number of hammer blows and decrease the particle size distribution. If the situation is severe, the roller 305 can be rotated to achieve a higher frequency of hammer blows and a wider range of finished product adjustments.

[0038] When materials are processed in the equipment, the adjustable curvature spiral lifting plate 403 and the main shaft 500 can rotate in the same direction or in opposite directions. When the adjustable curvature spiral lifting plate 403 rotates in the same direction as the main shaft 500, the probability of the material contacting the hammer 502 is small. When crushing materials, the material direction is the same as that of the hammer 502. At this time, the crushing mechanism is more of a shaping effect, so that the finished material has a cubic structure. When the adjustable curvature spiral lifting plate 403 rotates in the opposite direction to the main shaft 500, the probability of the material contacting the hammer 502 is greater. At this time, the material is hit by the hammer 502 more times, so as to realize the production of sand and fine finished products.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
