[0033] A grinding device for lead-zinc ore testing, comprising a first support frame 1, the top of the first support frame 1 is fixedly connected to a second support frame 2, the top inner walls of both sides of the second support frame 2 are fixedly connected to a crushing box 4, the top of the crushing box 4 is fixedly connected to a feed hopper 3, the bottom of the crushing box 4 is fixedly connected to an upper discharge port 5, the top inner walls of both sides of the first support frame 1 are fixedly connected to a connecting tube 7, the top of the connecting tube 7 is fixedly connected to a receiving hopper 6, the bottom of the connecting tube 7 is fixedly connected to a lower discharge port 10, and the outer surface of the first support frame 1 is provided with a grinding assembly 8. A screening assembly 9 is provided inside the first support frame 1. The screening assembly 9 is located below the discharge port 10. The crushed ore falls into the receiving hopper 6 through the upper discharge port 5, and then enters the connecting cylinder 7. In the connecting cylinder 7, the auger shaft 809 rotates driven by the second pulley 804. The spiral blades 810 on the outer surface of the auger shaft 809 further grind and push the ore, so that the ore forms a continuous grinding process in the connecting cylinder 7. The ground ore falls into the receiving box 901 of the screening assembly 9 through the lower discharge port 10.

[0034] Furthermore, the grinding assembly 8 includes a rotating shaft 807, crushing pieces 808, an auger shaft 809 and spiral blades 810. The crushing box 4 is internally rotatably connected to the rotating shaft 807, and the outer surface of the rotating shaft 807 is fixedly connected to a plurality of annular equidistantly distributed crushing pieces 808. The connecting tube 7 is internally rotatably connected to the auger shaft 809, and the outer surface of the auger shaft 809 is fixedly connected to the spiral blades 810. As the rotating shaft 807 rotates, the plurality of annular equidistantly distributed crushing pieces 808 fixed thereon begin to impact and shear the ore, thereby crushing the ore into smaller particles.

[0035] Furthermore, the grinding assembly 8 also includes a first motor 801, a first pulley 802, a first belt 803, a second pulley 804, a second belt 805 and a third pulley 806. The first motor 801 is fixedly installed inside the first support frame 1, and the output end of the first motor 801 is fixedly connected to the first pulley 802, the outer surface of the connecting cylinder 7 is rotatably connected to the second pulley 804, and the outer surface of the crushing box 4 is rotatably connected to the third pulley 806.

[0036] Furthermore, the third pulley 806 is fixedly connected to the rotating shaft 807, and the second pulley 804 is fixedly connected to the auger shaft 809. Since the third pulley 806 is fixedly connected to the rotating shaft 807, the rotating shaft 807 also rotates accordingly.

[0037] Furthermore, the screening assembly 9 includes a receiving box 901, a carrying box 902, a box door 903, a connecting plate 904 and a connecting rod 906. The outer surfaces of both sides of the top of the first support frame 1 are fixedly connected with connecting plates 904. The two connecting plates 904 are both arranged in an L-shaped structure. The carrying box 902 is fixedly connected between the two connecting plates 904. The outer surface of the carrying box 902 is hinged with a box door 903. The outer surfaces of both sides of the carrying box 902 are rotatably connected to two connecting rods 906. The other ends of the four connecting rods 906 are rotatably connected to the receiving box 901. The ore is pushed out from one side of the carrying box 902. The box door 903 of the carrying box 902 is designed to be easy to open for cleaning or maintenance when needed.

[0038] Furthermore, the screening assembly 9 also includes a connecting rod 907, a second motor 909 and a cam 912. The outer surface of the carrying box 902 is rotatably connected to the cam 912, and the second motor 909 is fixedly installed on the outer surface of the other side of the carrying box 902. The output end of the second motor 909 is fixedly connected to the cam 912. The non-center point of the cam 912 is fixedly connected to one end of the connecting rod 907, and the other end of the connecting rod 907 is fixedly connected to the material receiving box 901. When the second motor 909 is started, its output end drives the cam 912 to rotate. The non-center point of the cam 912 is fixedly connected to the material receiving box 901 through the connecting rod 907. Therefore, the rotation of the cam 912 will drive the material receiving box 901 to vibrate up and down.

[0039] Furthermore, a rectangular groove 911 is provided on the inner wall of the bottom of the carrying box 902, and a push plate 910 is slidably connected inside the rectangular groove 911. The push plate 910 is movably fitted with the inner wall of the carrying box 902. An electric push rod 908 is fixedly installed on the outer surface of the carrying box 902. The output end of the electric push rod 908 is fixedly connected to the push plate 910. The output end of the electric push rod 908 pushes the push plate 910 to slide in the rectangular groove 911, thereby pushing the ore out from one side of the carrying box 902. The box door 903 of the carrying box 902 is designed to be easy to open for cleaning or maintenance when needed.

[0040] Furthermore, a plurality of equally spaced through holes 905 are provided on the bottom inner wall of the receiving box 901 , and vibration causes smaller ore particles to fall into the carrying box 902 through the through holes 905 at the bottom of the receiving box 901 .

[0041] Furthermore, the upper discharge port 5 is located inside the receiving hopper 6, and the feed hopper 3 is conical. The lead-zinc ore to be processed is poured into the crushing box 4 through the conical feed hopper 3. The conical design helps the ore to fall smoothly into the crushing box and reduce the risk of blockage.

[0042] Working principle: when it is necessary to use the lead-zinc ore test grinding device, first pour the lead-zinc ore to be processed into the crushing box 4 through the conical feed hopper 3. The conical design helps the ore to fall into the crushing box smoothly and reduces the risk of blockage. When the ore enters the crushing box 4, start the first motor 801, and the output end of the first motor 801 drives the first pulley 802 to rotate, and transmits power to the second pulley 804 through the first belt 803. The second pulley 804 continues to drive the third pulley 806 to rotate through the second belt 805. Since the third pulley 806 is fixedly connected to the rotating shaft 807, the rotating shaft 807 also rotates accordingly. As the rotating shaft 807 rotates, a plurality of annular equidistantly distributed crushing pieces 808 fixed thereon begin to impact and shear the ore, breaking the ore into smaller particles. The crushed ore falls into the receiving hopper 6 through the upper discharge port 5, and then enters the connecting cylinder 7. In the connecting cylinder 7, the auger shaft 809 rotates under the drive of the second pulley 804 The spiral blades 810 on the outer surface of the auger shaft 809 further grind and push the ore, so that the ore forms a continuous grinding process in the connecting tube 7. The ground ore falls into the receiving box 901 of the screening component 9 through the lower discharge port 10. The second motor 909 is started, and its output end drives the cam 912 to rotate. The non-center part of the cam 912 is fixedly connected to the receiving box 901 through the connecting rod 907. Therefore, the rotation of the cam 912 will drive the receiving box 901 to vibrate up and down. This vibration The movement causes smaller ore particles to fall into the carrying box 902 through the through hole 905 at the bottom of the receiving box 901, while larger particles remain in the receiving box 901, thereby realizing a screening function. In order to clean the ore in the carrying box 902, the electric push rod 908 can be started, and the output end of the electric push rod 908 pushes the push plate 910 to slide in the rectangular groove 911, thereby pushing the ore out of one side of the carrying box 902. The box door 903 of the carrying box 902 is designed to be easy to open for cleaning or maintenance when necessary.
