[0001] The utility model relates to the technical field of hammer crushers, in particular to a coal slime hammer crusher. Background Art
[0002] Coal slime refers to a semi-solid substance formed by coal powder containing water. It is a product in the coal production process. During the production process, the coal slime needs to be air-dried first, and then crushed by a crusher. A hammer crusher is usually used to crush the coal slime. When the hammer crusher in the prior art crushes the coal slime, the dust generated by the crushing will be discharged through the feed port, affecting the health of the staff and affecting normal work. The feed port cannot limit the entry of coal slime with a large volume into the crusher. The entry of coal slime with a large volume into the crusher body will affect the crushing efficiency of the crusher. In severe cases, the crusher may get stuck and fail to work. Therefore, a coal slime hammer crusher is designed to solve the above problems. Utility Model Content
[0003] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a coal slime hammer crusher.
[0004] The technical problem to be solved by the utility model is to provide a coal slime hammer crusher, which can prevent dust from being discharged from the feed port, and can screen the coal slime with too large a volume to prevent the coal slime with too large a volume from entering the crusher, thereby ensuring the crushing efficiency and having high practicality.
[0005] The utility model provides a coal slime hammer crusher, comprising: a crusher body, a feed port, a baffle, a rotating shaft, and a motor. The feed port is penetrated on the left side of the upper surface of the crusher body, and a baffle is rotatably arranged above the feed port through the rotating shaft. A motor is fixedly arranged on the base of the crusher body, and a driving pulley is fixedly arranged on the output end of the motor. A transmission shaft is penetrated in the center of the crusher body, and a driven pulley is fixedly arranged on the outer end of the transmission shaft, and a transmission belt is sleeved between the driving pulley and the driven pulley, a grate plate is fixedly arranged on the inner side of the crusher body, a hammer disc is fixedly arranged on the transmission shaft, a plurality of hammer head shafts are fixedly arranged on the hammer disc, and a hammer head is rotatably arranged on the hammer head shaft.
[0006] Preferably, the feed port is tilted toward the lower right, and the tilt angle is 30°-60°.
[0007] Preferably, when the baffle is in a vertical state, the bottom thereof is in close contact with the inner bottom of the feed inlet.
[0008] Preferably, a limit rod is fixedly provided on the outer surface of the rotating shaft, a limit assembly is fixedly provided on the outer side of the feed port, the limit assembly includes a fixed plate, a threaded hole and a limit bolt, the fixed plate is fixedly provided on the outer surface of the feed port, a plurality of threaded holes are fixedly provided around the outer surface of the fixed plate, and the threaded inner holes are threadedly connected to the limit bolts.
[0009] Preferably, a through hole is opened in the center of the fixed disk, and the diameter of the through hole is not less than the diameter of the rotating shaft, and the rotating shaft passes through the through hole.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:
[0013] 1. The utility model is provided with a baffle, which is rotatably arranged on the feed port through a rotating shaft. When coal slime is added to the feed port, the gravity of the coal slime will squeeze the baffle, causing the baffle to rotate along the rotating shaft, and the bottom of the baffle will separate from the bottom of the feed port. The coal slime enters the crusher body through the gap between the baffle and the bottom of the feed port. After the material in the feed port completely enters the crusher body, the baffle is in a vertical state again under the action of the gravity of the baffle, blocking the feed port to prevent dust from being discharged from the feed port when the crusher body crushes the coal slime.
[0014] 2. The utility model is provided with a hammer shaft and a hammer head, and the hammer head is rotatably arranged on the hammer shaft, so that the hammer head can rotate along the hammer head, thereby reducing the force between the hammer head and the hammer disc when the hammer head hits the coal slime, preventing the hammer head from falling off from the connection of the hammer disc, and ensuring the service life.
[0015] 3. By setting a limit rod and a limit assembly, and by threading the limit bolt on the limit assembly into the threaded hole, when the shaft rotates, the limit rod will be driven to rotate. When the limit rod contacts the limit bolt, the limit rod can limit the rotation of the shaft, thereby achieving the effect of limiting the rotation angle of the baffle. By limiting the rotation angle of the baffle, materials with too large a volume can be prevented from entering the crusher body through the feed port, resulting in the crushing efficiency of the crusher body being affected. The rotation angle of the shaft and the baffle can be adjusted by threading the limit bolt into different threaded holes, so as to facilitate the control of the diameter of the coal slime entering the crusher body through the feed port.

[0023] Example:
[0024] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides a coal slime hammer crusher, comprising: a crusher body 1, a feed port 2, a baffle 3, a rotating shaft 301, and a motor 4. The feed port 2 is penetrated on the left side of the upper surface of the crusher body 1, and the baffle 3 is rotatably arranged above the feed port 2 through the rotating shaft 301. The motor 4 is fixedly arranged on the base of the crusher body 1, and a driving pulley 401 is fixedly arranged on the output end of the motor 4. A transmission shaft 5 is penetrated in the center of the crusher body 1, and a driven pulley 501 is fixedly arranged on the outer end of the transmission shaft 5, and a transmission belt 6 is sleeved between the driving pulley 401 and the driven pulley 501. A grate plate 7 is fixedly arranged on the inner side of the crusher body 1, a hammer disc 8 is fixedly arranged on the transmission shaft 5, and a plurality of hammer head shafts 901 are fixedly arranged on the hammer head shaft 901, and a hammer head 9 is rotatably arranged on the hammer head shaft 901.
[0025] During actual use, the coal slime to be crushed is added into the crusher body 1 through the feed port 2, and the gravity of the coal slime will squeeze the baffle 3, causing the baffle 3 to rotate along the rotating shaft 301, and the bottom of the baffle 3 will detach from the bottom of the feed port 2, and the coal slime will enter the crusher body 1. After the material in the feed port 2 completely enters the crusher body 1, under the action of the gravity of the baffle 3, the baffle 3 is in a vertical state again, blocking the feed port 2 to prevent dust from being discharged from the feed port 2 during crushing, and the motor 4 is turned on, and the motor 4 drives the active pulley 401 to rotate, and the active pulley 401 drives the transmission shaft 5 and the hammer plate 8 to rotate through the transmission belt 6, and the hammer plate 8 drives the hammer head 9 to rotate, and the hammer head crushes the coal slime. The crushed coal slime passes through the grate plate 7 and falls to the bottom of the crusher body 1, completing the crushing of the coal slime.
[0026] In this embodiment, the feed port 2 is tilted to the lower right, and the tilt angle is 30°-60°, so that the coal slime can enter the crusher body 1 along the bottom of the feed port 2 under the action of gravity.
[0027] Preferably, when the baffle 3 is in a vertical state, the bottom is in close contact with the inner bottom of the feed port 2, so that the baffle 3 can block the feed port 2, thereby preventing dust from being discharged from the feed port 2 when the crusher body 1 crushes the coal slime.
[0028] In this embodiment, refer to Figure 1-Figure 4 As shown, a limiting rod 302 is fixedly provided on the outer surface of the rotating shaft 301, and a limiting component is fixedly provided on the outer side of the feed port 2. The limiting component includes a fixed plate 10, a threaded hole 1001 and a limiting bolt 1002. The fixed plate 10 is fixedly provided on the outer surface of the feed port 2, and a plurality of threaded holes 1001 are fixedly provided around the outer surface of the fixed plate 10. The threaded inner surface of the threaded hole 1001 is connected to the limiting bolt 1002.
[0029] In this embodiment, a through hole is opened in the center of the fixed disk 10 , and the diameter of the through hole is not less than the diameter of the rotating shaft 301 . The rotating shaft 301 passes through the through hole, and the fixed disk 10 will not affect the rotation of the rotating shaft 301 .
[0030] In this embodiment, the length of the limiting bolt 1002 is not less than the distance between the limiting rod 302 and the fixing plate 10 , so that the limiting rod 302 can contact the limiting bolt 1002 easily.
[0031] In this embodiment, the length of the limiting rod 302 is not less than the length between the rotating shaft 301 and the threaded hole 1001 , so that the limiting rod 302 can contact the limiting bolt 1002 easily.
[0032] By setting a limit rod 302 and a limit assembly, and by threading the limit bolt 1002 on the limit assembly into the threaded hole 1001, when the rotating shaft 301 rotates, the limit rod 302 will be driven to rotate. When the limit rod 302 contacts the limit bolt 1002, the limit rod 302 can limit the rotation of the rotating shaft 301, thereby achieving the effect of limiting the rotation angle of the baffle 3. By limiting the rotation angle of the baffle 3, materials with too large a volume can be prevented from entering the crusher body 1 through the feed port 2, resulting in the crushing efficiency of the crusher body 1 being affected. The rotation angle of the rotating shaft 301 and the baffle 3 can be adjusted by threading the limit bolt 1002 into different threaded holes 1001, so as to facilitate the control of the diameter of the coal slime entering the crusher body 1 through the feed port.
