Description

Technical Field

[0001] The utility model relates to the technical field of sand making, in particular to a sand making device with adjustable processing particle size. Background Art

[0002] Sand making is mainly used in the construction field to provide sand for basic materials such as concrete and mortar. The process flow of the sand making production line includes the stone being evenly sent to the coarse crusher by vibration for coarse crushing, and the coarse crushed material is sent to the sand making machine by the belt conveyor for further crushing. The finely crushed material is transported to the vibrating screen for screening, and the qualified material after screening is sent to the sand washing machine for cleaning, and then the finished product is transported. Among them, various crushing machines are generally used to crush the stone during coarse crushing.

[0003] Impact crusher is a kind of crushing machine that uses impact energy to crush materials and is often used in sand making. Impact crusher is generally composed of rotor, impact plate, bearing and shaft seat, frame, adjustment device, lubrication system and electrical system.

[0004] However, the prior art has the following defects:

[0005] When adjusting the particle size of the impact crusher, it is generally achieved by adjusting the impact lining and the rotor position. Since the stone material continuously hits the impact plate for a long time, the impact plate is seriously worn, and it needs to be replaced regularly. However, due to the different positions of the impact plates, the degree of wear is also different, and since the impact lining and the impact plate are fixed as one, a complete replacement is required at one time, which is costly and wastes resources. Utility Model Content

[0006] In order to solve the technical problem that when one or several impact plates are seriously worn, the impact lining plate needs to be replaced to ensure the discharge particle size, resulting in high cost, the utility model provides a sand making device with adjustable processing particle size.

[0007] The utility model adopts the following technical scheme to achieve: a sand making device with adjustable processing particle size.

[0008] The invention comprises a housing, a rotor is arranged in the housing, and one end of the rotor is connected to a driving system to provide power to the rotor, a hammer plate is arranged outside the rotor, a groove for a hydraulic cylinder to penetrate is opened on one side of the hammer plate, and one end of the hydraulic cylinder is located inside the housing and connected to a counter-attack lining plate, and the other end of the hydraulic cylinder is located outside the housing and provided with a frame;

[0009] The engagement adjustment mechanism includes an impact bar, an engagement adjustment unit and a limiting unit. The impact bar is installed on the impact lining plate through the engagement adjustment unit, and the position of the impact bar is fixed by the limiting mechanism.

[0010] The range locking mechanism includes a mounting plate and a range locking unit. The mounting plate is fixedly connected below the impact bar, and range locking units are provided on both sides of the mounting plate to lock the moving distance of the impact bar.

[0011] Through the above technical solution, the counter bar can be replaced individually under the action of the meshing adjustment mechanism, and the distance between the counter bar and the rotor and the hammer plate can be adjusted individually, thereby extending the service life of the counter bar. When the distance between the counter bar and the rotor and the hammer plate is adjusted under the action of the range locking mechanism, the moving range of the counter bar can be limited, thereby ensuring the stability of the counter bar when moving.

[0012] As a further improvement of the above scheme, the meshing adjustment unit comprises a rack plate, a limiting groove, a ball, a rotating rod 1, a gear 1, a rotating rod 2 and a gear 2, one end of the two rack plates can be detachably installed on the counter-attack bar, a rack is provided on the adjacent side of the two rack plates, a plurality of ball bearings are provided on the side of the two rack plates away from each other, and the ball bearings contact the limiting groove, one end of the rotating rod 1 is installed with a bearing inside the limiting groove, a gear 1 is provided outside the rotating rod 1, and the gear 1 and the rack plate form a meshing connection structure, both ends of the rotating rod 2 are bearing-connected to the limiting groove and are located below the rotating rod 1, the gear 2 is fixed on the rotating rod 2, and the outside of the gear 2 respectively forms a meshing connection structure with the rack plate and the gear 1.

[0013] Through the above technical solution, the rotation of the rotating rod 1 drives the gear 1 to rotate so that the rack plate extends out or enters the limit groove, so that when the impact bar is worn and the distance from the rotor and the hammer plate is too far to reach the crushing particle size, the impact bar moves closer to the rotor and the hammer plate to ensure the crushing particle size effect, so that the impact bar can be used for a longer life. And under the action of the ball, not only can the rack plate enter the limit groove more smoothly, but also the rack plate can be more stable when it is inside the limit groove.

[0014] As a further improvement of the above solution, the other end of the rotating rod passes through a slot opened on one side of the limiting slot, is located outside the counterattack liner, and is provided with a rotating handle.

[0015] Through the above technical solution, by providing a turning handle on the rotating rod 1 outside the impact lining plate, the rotating rod 1 can be driven more conveniently, thereby realizing the distance adjustment work between the impact bar and the rotor and the hammer plate.

[0016] As a further improvement of the above scheme, the limiting unit comprises gear three, a gear ring, a screw and a fixed plate, wherein the gear three is fixed on the rotating rod one and is located outside the impact liner, the fixed plate is arranged outside the impact liner on one side of the gear three, a groove is opened on the fixed plate to form a threaded connection structure with the outside of the screw, the middle part of the screw is located in the above groove, the gear ring is arranged at one end of the screw, and the gear ring is clamped on the outside of the gear three.

[0019] Through the above technical solution, the magnets arranged on the slide rail and the slider attract each other, which can ensure that the insertion rod is stably inserted, thereby limiting the overall range of the impact bar, so that when adjusting the impact bar, it is more labor-saving to not use hands to hold the impact bar to prevent it from falling.

[0020] As a further improvement of the above scheme, the range locking unit slot, insertion rod, movable groove, inclined block one, inclined block two, pressing groove, pressing rod and spring, the slots are all opened on the side where the sliders are away from each other, one end of the insertion rod is inserted in the slot, and one end of the movable groove is opened on both sides of the limiting groove, the pressing groove is opened at the other end of the movable groove, and a slot that can allow the insertion rod to move is formed between the limiting groove, the movable groove and the pressing groove, the inclined block one is arranged at the end of the insertion rod away from the slot, one end of the pressing rod is provided with a screw groove, and one end of the inclined block two is arranged at the other end of the pressing rod, the other end of the inclined block two contacts with the inclined block one, one end of the spring is welded to the insertion rod, and the other end of the spring is welded to the limiting groove.

When the impact bar needs to be removed, the pressing rod and the impact lining plate are first separated, and the insertion rod is pulled gradually away from the slot under the rebound potential energy of the spring, and the impact bar can be pulled out.

[0036] The meshing adjustment unit comprises a rack plate 7, a limit groove 8, a ball 9, a rotating rod 10, a gear 11, a rotating rod 2 12 and a gear 2 13. One end of the two rack plates 7 can be detachably mounted on the counter-attack bar 6. A long plate is provided at one end of the rack plate 7, and the long plate is connected to the counter-attack bar 6 by bolts. Therefore, when replacing the counter-attack bar 6, it is only necessary to separate the rack plate 7 from the counter-attack bar 6 and then fix the rack plate 7 on the new counter-attack bar 6. A rack is provided on one side adjacent to the two rack plates 7, and a plurality of ball bearings are provided on the side away from each other of the two rack plates 7, and the ball bearings are in contact with the limiting groove 8. A bearing at one end of a rotating rod 10 is installed inside the limiting groove 8, and a gear 11 is provided on the outside of the rotating rod 10, and the gear 11 and the rack plate 7 form a meshing connection structure. Both ends of a rotating rod 12 are bearing-connected to the limiting groove 8 and are located below the rotating rod 10, and a gear 2 13 is fixed on the rotating rod 12, and the outside of the gear 2 13 respectively forms a meshing connection structure with the rack plate 7 and the gear 11.

[0037] The other end of the rotating rod 10 passes through the slot opened on one side of the limiting slot 8 and is located outside the counter-attack liner 5 and is provided with a rotating handle.

[0038] The implementation principle of a sand making device with adjustable particle size in the embodiment of the present application is as follows: the stone enters from the feed port on one side of the housing 1, and when the stone material enters the action area of ​​the hammer plate 3 in coordination with the rotation of the rotor 2, the crushed material is continuously thrown to the impact bar 6 installed above the rotor for crushing by the high-speed impact of the hammer plate 3, and then bounces back from the impact bar 6 to the action area of ​​the hammer plate 3 to be counterattacked again, thereby completing the crushing work, and the crushed stone flows out from the discharge port below the housing 1. When the overall position of the impact liner 5 and the hammer plate 3 need to be adjusted, the hydraulic cylinder 4 is started to move the impact liner 5 closer to the hydraulic cylinder 4.

[0039] When the counter-attack bar 6 needs to be installed, first push the slider 20 to slide on the slide rail 19, so that the magnet on the slider 20 and the magnet on one side of the slide rail 19 are attracted to each other, and the position of the slider 20 is limited. Pick up the counter-attack bar 6 and move the two rack plates 7 into the limiting groove 8, and the two rack plates 7 respectively form a meshing connection structure with the gear 1 11 and the gear 2 13, driving the gear 1 11 and the gear 2 13 to rotate while driving the rotating rod 10 to rotate. When the rack plate 7 completely enters the limiting groove 8, the screw 16 is rotated so that the screw 16 drives the gear ring 15 to approach the gear 3 14 and contact with the gear 3 14. At this time, the rotating rod 10 can be The position of the counter-attack bar 6 is limited, thereby fixing the position of the counter-attack bar 6, and extending the pressing rod 27 into the pressing groove 26 and moving downward so that the inclined block 25 contacts the inclined block 1 24, and the pressing rod 27 is tightly clamped in the screw groove opened on the rack plate 7 with a bolt, so that the pressing rod 27 continues to extend into the pressing groove 26, and the inclined block 25 gradually fits with the inclined block 1 24 to stretch the spring 28 and drive the insertion rod 22 to move in the direction of the limit groove 8 inside the movable groove 23, and is inserted in the slot 21, so that the counter-attack bar 6 can be locked within the range. When the counter-attack bar 6 needs to be removed and replaced, the pressing rod 27 is first moved out to release the limit on the gear ring 15, and the counter-attack bar 6 can be directly pulled out.

[0040] When it is found that one of the impact bars 6 is severely worn and the distance between it and the plate hammer is larger than before, the screw rod 16 is first rotated, and the toothed ring 15 is gradually moved away from the gear three 14 under the threaded connection between the outside of the screw rod 16 and the fixed plate 17, and the gear three 14 cannot be limited. Under the action of gravitational potential energy, the impact bar 6 falls downward, driving the slide rail 19 to move to the outside of the limiting groove 8, so that the other side of the slide rail 19 and the slider 20 fit together to limit the impact bar 6. At this time, the turning handle connected to one side of the rotating rod 10 drives the rotating rod 10 to rotate, so that the gear three 14 rotates and drives the gear 11 to rotate.

When the counter-attack bar 6 and the other counter-attack bars 6 are almost flush with each other, the turning handle on one side of the turning rod one 10 is stopped and kept stationary, and the screw rod 16 is rotated so that the screw rod 16 drives the gear ring 15 to gradually approach the gear three 14 and fit with the gear three 14 to limit the gear three 14. At this time, the turning handle connected to the turning rod one 10 can be loosened to adjust the gap between the counter-attack bar 6 and the hammer plate.
