[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-5 As shown, an embodiment of the present invention provides a single-stage crusher that is easy to maintain, including a casing 1, an outer wall of one side of the casing 1 is connected to a maintenance door 3 by a hinge, an outer wall of one side of the casing 1 is rotatably connected to a rotating plate 4, the rotating plate 4 is adapted to the maintenance door 3, the interior of the rotating plate 4 is connected to a screw rod 5 by a thread, and a force rod 6 is inserted into the interior of the screw 5, a shell 2 is fixed to the bottom of the casing 1, a sieve plate 7 is provided inside the shell 2, a support plate 12 is fixed to the inner wall of the shell 2, a guide column 13 is fixed to the bottom outer wall of the sieve plate 7, the guide column 13 is movably inserted into the interior of the support plate 12, a stopper 11 is fixed to the bottom end of the guide column 13, a spring 14 is sleeved on the outside of the guide column 13, and the spring 14 is located between the support plate 12 and the sieve plate 7.
[0022] Specifically, in this embodiment, it includes a casing 1, and the casing 1 has a crushing mechanism of a single-stage crusher in the prior art. An outer wall of one side of the casing 1 is connected to a maintenance door 3 through a hinge. An outer wall of the casing 1 has an inspection port, which is covered by the inspection door 3. An outer wall of one side of the casing 1 is rotatably connected to a rotating plate 4. The number of rotating plates 4 is preferably 4, and the rotating plates 4 are installed around the outer side of the inspection door 3. The rotating plates 4 are adapted to the inspection door 3 and can block the inspection door 3 when the rotating plates 4 rotate. The interior of the rotating plate 4 is connected to a screw rod 5 through a thread. The screw rod 5 can interfere with the inspection door 3 when it rotates, so that the inspection door 3 is fixed to the casing 1. The screw rod 5 is inserted into the interior of the screw rod 5. The force rod 6 is used to facilitate the rotation of the screw 5. The bottom of the casing 1 is fixed with a shell 2, and a sieve plate 7 is provided inside the shell 2. The sieve plate 7 is installed at an angle. The inner wall of the shell 2 is fixed with a support plate 12. The bottom of both ends of the sieve plate 7 has a support plate 12. The bottom outer wall of the sieve plate 7 is fixed with a guide column 13, which is movably inserted into the inside of the support plate 12. The guide column 13 can move up and down inside the support plate 12. The bottom end of the guide column 13 is fixed with a stopper 11, and the stopper 11 is used to prevent the guide column 13 from being separated from the support plate 12. The outside of the guide column 13 is sleeved with a spring 14, which is located between the support plate 12 and the sieve plate 7, and the spring 14 is used to support the sieve plate 7.
[0023] The utility model provides a single-stage crusher which is easy to maintain. The screw 5 is rotated so that the screw 5 does not interfere with the maintenance door 3, and then the rotating plate 4 is rotated so that the rotating plate 4 does not block the maintenance door 3, so that the maintenance door 3 can be conveniently opened, thereby achieving the effect of facilitating maintenance of the crusher.
[0024] In another embodiment provided by the present invention, the interior of the casing 1 is connected to the rotor 22 through a bearing, and the outer wall of one side of the rotor 22 is hinged with hammers 23 distributed symmetrically in the center. The rotor 22 and the hammers 23 are the crushing mechanisms of the single-stage crusher of the prior art. At the same time, the interior of the casing 1 also has an impact plate and a grate plate, etc., so that the material can be crushed into an ideal state. One end of the connecting shaft of the rotor 22 extends to the outside of the casing 1 and is fixed with a driving pulley 18. When the driving pulley 18 rotates, it drives the rotor 22 to rotate; the interior of the casing 2 is connected to the rotating shaft 21 through a bearing, and one end of the rotating shaft 21 extends to the outside of the casing 2 and is fixed with a driven pulley 19. When the driven pulley 19 rotates, it drives the rotating shaft 21 to rotate. The driven pulley 19 and the driving pulley 18 are connected by a belt drive. When the driving pulley 18 rotates, it drives the driven pulley 19 to rotate; the outside of the rotating shaft 21 is fixed with a fixing ring 15, and the outer wall of the fixing ring 15 is integrally formed with evenly distributed protrusions. 16. The bottom of the fixing ring 15 contacts the sieve plate 7. When the rotating shaft 21 rotates, the protrusion 16 on the outside of the fixing ring 15 can drive the sieve plate 7 to vibrate, and the fixing ring 15 is driven to rotate by the provided rotating shaft 21, and the protrusion 16 on the fixing ring 15 rubs against the sieve plate 7, so that the sieve plate 7 vibrates under the support of the spring 14, thereby causing the sieve plate 7 to be stuck and shaken off, preventing the sieve plate 7 from being blocked, and at the same time, it can enable the sieve plate 7 to maintain an efficient screening effect; and the larger diameter active pulley 18 drives the smaller diameter driven pulley 19 to rotate, achieving the effect of increasing the speed of the driven pulley 19, thereby making the rotating shaft 21 obtain a higher speed, so that the vibration frequency of the sieve plate 7 is increased; a mounting bracket 17 is fixed to the outer wall of one side of the casing 1, and a reduction motor 20 is fixed to the outer wall of one side of the mounting bracket 17. The output shaft of the reduction motor 20 is connected to the active pulley 18 by a key, and the reduction motor 20 drives the active pulley 18 to rotate.
[0025] In another embodiment provided by the present invention, a guide plate 10 is fixed inside the casing 1, and the guide plate 10 is located at the bottom of the rotor 22. The guide plate 10 can drop the material to a high position on the sieve plate 7, so that the material can be fully screened by the sieve plate 7. A discharge hopper 8 is fixed to the side wall of the shell 2, and the discharge hopper 8 is adapted to the sieve plate 7. The material that does not pass through the sieve plate 7 flows out from the discharge hopper 8. A discharge port 9 is provided on the bottom outer wall of the shell 2, and the fine material that passes through the sieve plate 7 flows out from the discharge port 9, thereby achieving the effect of separating two materials of different specifications.
[0026] Working principle: When in use, the reduction motor 20 drives the active pulley 18 and the rotor 22 to rotate, the active pulley 18 drives the driven pulley 19 to rotate, the driven pulley 19 drives the rotating shaft 21 and the fixed ring 15 to rotate, and when the fixed ring 15 rotates, the multiple protrusions 16 on its outer wall squeeze the sieve plate 7 in sequence. Since the bottom of the sieve plate 7 is supported by the spring 14, the sieve plate 7 vibrates; when the material needs to be crushed, the material is put into the interior of the casing 1, so that when the rotor 22 rotates, the material is crushed. The material is crushed by the hammer head 23, and after being crushed by the hammer head 23, it collides with the impact plate inside the casing 1, so that the material is further crushed, and then the material passes through the internal grate plate and falls on the screen plate 7; under the action of the screen plate 7, the material with larger particles flows out from the discharge hopper 8 along the screen plate 7, and the material with smaller particles passes through the screen plate 7 and flows out from the discharge port 9. At the same time, when the screen plate 7 vibrates, it can shake off the material stuck on the screen plate 7 to prevent the screen plate 7 from being blocked, so that the screen plate 7 can efficiently screen the material.
[0027] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
