[0016] 1.

[0019] 4. The present invention provides an adjusting component which can adjust the size of the opening at the bottom of the feed hopper, thereby controlling the feed amount per unit time. During adjustment, the telescopic cylinder located outside the feed hopper contracts to make the adjusting plates on both sides approach each other, and vice versa, the adjusting plates on both sides move away from each other, thereby adjusting the size of the opening at the bottom of the feed hopper.

[0020] 5. The present invention sets an adjusting component. During the material discharge process, the support frame located at the bottom of the screen drives the elastic rod to perform reciprocating motion. When the elastic rod moves downward, the scraper rod presses the adjusting plate downward and forces the elastic rod to produce elastic deformation. At this time, the scraper rod can push the material that falls on the top of the adjusting plate from the top of the adjusting plate when moving downward, thereby preventing the material from accumulating on the top of the adjusting plate.

[0021] 6. The present invention provides an adjusting component so that the support frame can drive the mounting frame to make reciprocating motion. At this time, the mounting frame can drive the shovel plate to slide along the side wall of the adjusting plate through the telescopic rod to prevent the material from adhering to the side wall of the adjusting plate. At the same time, the material in the feed hopper can be dredged through the movement of the support frame and the shovel plate to prevent the material from being blocked at the bottom of the feed hopper.

[0022] 7. The present invention provides a telescopic rod, so that when the device is in use, if the position of the adjustment plate changes, the telescopic rod can be extended and retracted to prevent the shovel plate and the adjustment plate from interfering with each other in movement, so that when the device is in use, the size of the opening at the bottom of the feed hopper can be adjusted, thereby improving the flexibility of the device.

[0023] 8. The present invention sets a water inlet assembly, and the water inlet pipe is connected to the water pipe outside. At this time, the rotating drum drives the crankshaft to rotate by rotating the diverter pipe. When the crankshaft rotates, it can drive the sealing plate to reciprocate in the water inlet pipe through the movable rod. When the sealing plate runs to the lower dead point, the water entering the water inlet pipe can enter the shell through the bypass pipe, and finally enter the rotating drum through the rotating diverter pipe, thereby automatically completing the water adding process when the device is running.

[0024] 9. The present invention isolates the shell into two chambers by setting a partition, so that water cannot contact the movable rod when flowing. Water may contain various chemicals and impurities, and contact with the movable rod will cause rust and corrosion of metal parts, reduce its strength and durability, and shorten its service life, thereby extending the service life of the movable rod.

[0025] 10. The present invention provides a material adding component and a water inlet component, and the movement frequency of the material adding component and the water inlet component is proportional to the rotation speed of the cylinder. The faster the rotation speed of the cylinder, the more material and water are added to the cylinder per unit time. Therefore, the equal ratio addition of water and ore material can be achieved through the rotation of the cylinder, which helps to improve the fluidity of the material in the ball mill, so that the grinding medium and the ore can fully contact and act, thereby improving the grinding efficiency and effect.

[0045] Working principle:

[0046] When in use, ore and water are added to the crushing device 2 through the feeding device 7 on the top of the bracket 8, and then the driving motor 4 on the top of the base 1 drives the gear ring 6 to rotate through the driving gear 5, so that the cylinder 21 rotates together with the gear ring 6. At this time, the two sides of the cylinder 21 drive the feeding pipe 23 and the discharging pipe 25 to rotate along the corresponding bearing seat 3 through the front cover 22 and the rear cover 24 respectively. At this time, the steel balls and ore in the cylinder 21 can be squeezed and worn against each other on the surface of the lining steel plate 28, completing the ore crushing process;

[0047] The crushed material is screened by setting a conical protective shell 26, so that after the liquid level in the cylinder 21 reaches the discharge pipe 25, the powder with qualified particle size can enter the discharge pipe 25 along with the water flow through the conical protective shell 26, and the discharge pipe 25 can be rotated and the material can be transported to the outside of the device by the rear spiral plate 27 set in the discharge pipe 25;

[0048] When the driving motor 4 is running, the ore after preliminary crushing is added to the feeding assembly 74, and at the same time, a water pipe is connected to the outside of the water inlet assembly 76. At this time, the feeding pipe 23 drives the drum 72 to rotate in the housing 71. At this time, the water in the water inlet assembly 76 and the materials in the feeding assembly 74 enter the drum 72. At this time, after being transported by the front spiral plate 73 in the drum 72, the materials mixed with water can enter the drum 72;

[0049] During this process, when the protrusion 75 contacts the top plate 742, the top plate 742 is squeezed upward and forces the compression spring 744 to be compressed. At this time, the connecting rod 743 drives the screen 745 to move upward along the inner side of the feed hopper 741. When the protrusion 75 is separated from the top plate 742, the compression spring 744 drives the screen 745 to reset. As a result, the screen 745 can reciprocate in the feed hopper 741 when the device is running, and the ore material added to the feed hopper 741 is screened to make the ore particle size entering the ball mill more uniform; this can reduce the ineffective work of the ball mill, improve the grinding efficiency, shorten the grinding time, and reduce energy consumption; and too large ore particles may cause excessive wear and impact on the lining and grinding medium of the ball mill, and even cause equipment failure; early screening can reduce such damage, extend the service life of the ball mill, and reduce maintenance costs.

[0050] The adjusting component 749 can adjust the opening size of the bottom of the feed hopper 741, so as to control the feeding amount per unit time. When adjusting, the telescopic cylinder 902 located outside the feed hopper 741 contracts to make the adjusting plates 901 on both sides close to each other, and vice versa, the adjusting plates 901 on both sides move away from each other, thereby adjusting the opening size of the bottom of the feed hopper 741;

[0051] During the material discharge process, the support frame 746 at the bottom of the screen 745 drives the elastic rod 747 to reciprocate together. When the elastic rod 747 moves downward, the scraper rod 748 presses the adjustment plate 901 downward and forces the elastic rod 747 to produce elastic deformation. At this time, the scraper rod 748 can push the material that falls on the top of the adjustment plate 901 from the top of the adjustment plate 901 when moving downward, thereby preventing the material from accumulating on the top of the adjustment plate 901.

[0052] During this process, the support frame 746 can drive the mounting frame 905 to make a reciprocating motion, and the mounting frame 905 can drive the shovel plate 903 to slide along the side wall of the adjustment plate 901 through the telescopic rod 904 to prevent the material from adhering to the side wall of the adjustment plate 901. At the same time, the movement of the support frame 746 and the shovel plate 903 can also be used to dredge the material in the feed hopper 741 to prevent the material from being blocked at the bottom of the feed hopper 741.

[0053] Among them, by setting the telescopic rod 904, when the device is in use, if the position of the adjustment plate 901 changes, the telescopic rod 904 can be extended and retracted to prevent the shovel plate 903 from interfering with the adjustment plate 901, so that when the device is in use, the opening size at the bottom of the feed hopper 741 can be adjusted, thereby improving the flexibility of the device;

[0054] When the water inlet assembly 76 is in use, the water inlet pipe 762 is connected to an external water pipe. At this time, the rotating drum 72 drives the crankshaft 766 to rotate by rotating the diverter pipe 765. When the crankshaft 766 rotates, it can drive the sealing plate 768 to reciprocate in the water inlet pipe 762 through the movable rod 767. When the sealing plate 768 runs to the lower dead point, the water entering the water inlet pipe 762 can enter the housing 761 through the bypass pipe 763, and finally enter the rotating drum 72 by rotating the diverter pipe 765, thereby automatically completing the water adding process when the device is running;

[0055] The housing 761 is isolated into two chambers by setting a partition 764, so that the water flow cannot contact the movable rod 767 when flowing. The water may contain various chemicals and impurities, and contact with the movable rod 767 will cause the metal parts to rust and corrode, reduce their strength and durability, and shorten their service life, thereby extending the service life of the movable rod 767;

[0056] The movement frequency of the feeding assembly 74 and the water inlet assembly 76 is proportional to the rotation speed of the cylinder 21. The faster the rotation speed of the cylinder 21, the more material and water are added to the cylinder 21 per unit time. Therefore, the equal ratio addition of water and ore material can be achieved through the rotation of the cylinder 21, which helps to improve the fluidity of the material in the ball mill and make the grinding medium fully contact and act with the ore, thereby improving the grinding efficiency and effect.
