Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically a mineral powder raw material crusher. Background Technology

[0002] Mineral powder raw materials are mainly solid wastes from mineral processing or mining. Mineral powder raw materials are widely used as admixtures in concrete. However, mineral powder raw materials have large particles and need to be crushed randomly using mineral powder raw material skins before being put into use.

[0003] Existing mineral powder crushers use a drive assembly to rotate a turntable, which in turn drives the hammers on the turntable to hammer the mineral powder. At the same time, the mineral powder impacts the impact plate inside the crusher, thereby improving the crushing efficiency. After crushing, the mineral powder that meets the requirements is discharged through the filter screen inside the crusher.

[0004] The existing mineral powder crushers use bolts and nuts to install and fix the internal filter screen. When replacing or removing the filter screen, the crusher needs to be disassembled first, and then the filter screen needs to be removed. The disassembly process is cumbersome and increases the burden on operators. Therefore, we propose a mineral powder crusher. Utility Model Content

A motor 3 is fixedly connected to the left side of the upper surface of the support frame 1. A pulley 4 is fixedly connected to the front end of the output shaft of the motor 3. The pulley 4 and the pulley 5 are connected by belt drive. The input end of the motor 3 is electrically connected to the output end of the control switch 12. When the control switch 12 is operated, the motor 3 is started. The output shaft of the motor 3 rotates, which drives the pulley 4 to rotate, drives the pulley 5 to rotate, and causes the main shaft 6 to rotate, which drives the turntable 7. The turntable 7 rotates, which drives the hammer 8 to rotate around the central axis of the turntable 7. The mineral powder raw material is fed into the inside of the machine housing 2 through the feed port on the upper side of the machine housing 2. The rotating hammer 8 hammers the mineral powder raw material. At the same time, the mineral powder raw material hits the impact plate 10, thereby crushing the mineral powder raw material. A protective door 13 is hinged to the rear surface of the machine housing 2. The lower side of the protective door 13 is fixedly connected to the machine housing 2 by bolts. It also includes a fixing mechanism 9.

[0024] Fixed mechanism 9 includes an arc-shaped insertion plate 901, an arc-shaped rack plate 902, a drive shaft 903, and a gear 904. The arc-shaped insertion plates 901 are slidably connected to the left and right sides of the interior of the housing 2. Arc-shaped grooves are provided on both the left and right sides of the interior of the filter screen 11, and the arc-shaped insertion plates 901 are inserted into the arc-shaped grooves on the same side. The outer arc surfaces of the arc-shaped insertion plates 901 are fixedly connected to the arc-shaped rack plates 902. The drive shaft 903 is rotatably connected to both the left and right sides of the interior of the housing 2. The rear side of the outer surface of the drive shaft 903 is fixedly connected to the gear 904. The gear 904 is fixedly connected to the gear on the same side. The arc-shaped rack plate 902 is engaged with the fixed mechanism 9, which also includes a bevel gear 905, a transmission shaft 906, a bevel gear 907, a worm gear 908, a worm 909, and a rotating handle 910. The bevel gears 905 are all fixedly connected to the front of the outer surface of the transmission shaft 903. The transmission shaft 906 is rotatably connected to the front of the inner side of the housing 2. The bevel gears 907 are symmetrically distributed on the left and right sides of the outer surface of the transmission shaft 906. The bevel gears 907 are all engaged with the bevel gears 905 on the same side. The worm gear is fixedly connected to the right side of the outer surface of the transmission shaft 906. 908. A worm gear 909 is rotatably connected to the front side of the inner casing 2. The worm gear 909 meshes with a worm wheel 908. A rotating handle 910 is fixedly connected to the front end of the worm gear 909.

The front surface of the filter screen 11 has symmetrically distributed insertion holes, and the insertion rods 911 are all inserted into the insertion holes on the same side. When the filter screen 11 needs to be replaced, the protective door 13 is opened, and the rotating handle 910 is rotated to rotate the worm gear 909, which in turn rotates the worm wheel 908, causing the transmission shaft 906 to rotate. The first bevel gear 905 rotates, which in turn rotates the first transmission shaft 903, causing the gear 904 to rotate. This rotates the arc-shaped rack plate 902, which in turn moves the arc-shaped insertion plate 901, causing it to move out of the arc-shaped groove. At this point, the filter screen 11 is pulled backward, separating the insertion rod 911 from the slot, thus replacing the filter screen 11. After replacement, the filter screen 11 is pushed forward, and the insertion rod 911 is inserted into the slot. The handle 910 is then turned to insert the arc-shaped insertion plate 901 into the arc-shaped groove, completing the installation of the filter screen 11.

[0025] The working principle of the mineral powder crusher provided by this utility model is as follows: When using the mineral powder crusher, operate the control switch 12 to start the motor 3. The output shaft of the motor 3 rotates, driving the pulley 4 to rotate, driving the pulley 5 to rotate, causing the main shaft 6 to rotate, driving the turntable 7, and causing the hammers 8 to rotate around the central axis of the turntable 7. The mineral powder is fed into the inside of the casing 2 through the feed port on the upper side of the casing 2. The rotating hammers 8 hammer the mineral powder, and at the same time, the mineral powder hits the impact plate 10, thereby crushing the mineral powder. The crushed mineral powder falls into the filter screen 11 on the lower side of the inside of the casing 2. The mineral powder that has reached the crushed size falls out from the lower side of the casing 2 through the filter screen 11, while the mineral powder that has not reached the crushed size is crushed by the hammers. The crushing process continues. When it is necessary to replace the filter screen 11, open the protective door 13, rotate the handle 910 to rotate the worm gear 909, drive the worm wheel 908 to rotate, drive the transmission shaft 906 to rotate, drive the bevel gear 907 to rotate, drive the bevel gear 905 to rotate, drive the transmission shaft 903 to rotate, drive the gear 904 to rotate, drive the arc-shaped rack plate 902 to move, and drive the arc-shaped insertion plate 901 to move, so that the arc-shaped insertion plate 901 leaves the arc-shaped groove. At this time, pull the filter screen 11 backward to separate the insertion rod 911 from the slot, thereby replacing the filter screen 11. After the replacement is completed, push the filter screen 11 forward to insert the insertion rod 911 into the slot, flip the handle 910 to insert the arc-shaped insertion plate 901 into the arc-shaped groove, and complete the installation of the filter screen 11.

[0026] It is worth noting that the motor 3 disclosed in the above embodiments is Y3-160M-4, and the control switch 12 is provided with a control button corresponding to the motor 3 and used to control its switch.
