[0038] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0039] Example:

[0040] See also Figure 1-Figure 3, an ore crushing device, comprising a frame (not shown in the figure), a shell 1, a screen 2, a rotor 3, a hammer 4, a support plate 5 and a plate 6. The shell 1 is arranged on the frame, the shell 1 is a cylindrical structure, the interior of the shell 1 is a hollow structure, the shell 1 is arranged in a horizontal direction, and the top of the shell 1 has a material inlet, and the top of the shell 1 has a material outlet.

[0041] A screen 2 is arranged on the discharge port at the bottom of the shell 1 . The screen 2 is arc-shaped, and the radius of the screen 2 is equal to the radius of the shell 1 .

[0042] Both ends of the rotor 3 are rotatably disposed in the housing 1 , and a plurality of hammer bodies 4 are disposed on the rotor 3 . The hammer bodies 4 are connected to the rotor 3 via connecting rods.

[0043] The support plate 5 is rotatably disposed on one end portion of the housing 1 . The support plate 5 is circular, and the axis of the support plate 5 is colinear with the axis of the housing 1 . Meanwhile, a plurality of plate members 6 are disposed on the support plate 5 .

[0044] One end of the plate 6 is fixedly connected to the support plate 5, and the length direction of the plate 6 is perpendicular to the plate surface of the support plate 5. There are a plurality of plate members 6 evenly distributed around the support plate 5, and all the plate members 6 are arranged close to the edge of the support plate 5.

[0045] In this embodiment, a rotating rotor 3 is arranged in the shell 1, and the hammer body 4 is swung in the shell 1 by the rotor 3, so that the ore entering the shell 1 from the feed port can be crushed.

[0046] The ore deposited at the bottom of the shell 1 is driven to a certain height by the rotation of the support plate 5 and the plate member 6 and then falls down, and is struck by the hammer 4 again to be broken.

[0047] The technical solution can effectively solve the problem that a large volume of ore is deposited on the screen 2, causing the screen 2 to be blocked.

[0048] In one specific embodiment:

[0049] The two ends of the shell 1 are hollow structures, and two support plates 5 are respectively located at the two ends of the shell 1, and the support plates 5 and the shell 1 are coaxially arranged. There is a gap between the outer edges of the two support plates 5 and the inner wall of the shell 1, and the two support plates 5 are rotatably arranged on the frame. The two ends of all the above-mentioned plates 6 are fixedly arranged on the two support plates 5 respectively.

[0050] The middle of the support plate 5 has a through hole, and the two ends of the rotor 3 pass through the two through holes respectively. Meanwhile, both ends of the rotor 3 are rotatably arranged on the frame.

[0051] Preferably, the ore crushing device further comprises a motor 7, a gear 8, a gear ring 9, two pulleys 10 and a belt 11. The motor 7 is fixedly arranged on the frame, and the gear 8 is coaxially arranged on the output shaft of the motor 7.

[0052] The gear ring 9 is coaxially arranged on one of the support plates 5 and is located outside the housing 1 . The gear ring 9 is meshed with the gear 8 .

[0053] One of the pulleys 10 is coaxially arranged on the output shaft of the motor 7 , and the other pulley 10 is coaxially arranged on one end of the rotor 3 . The two guide wheels are connected in power via a belt 11 .

[0054] In this embodiment, the motor 7 directly drives the gear 8 and the gear ring 9 to rotate, thereby driving the support plate 5 and the plate member 6 to rotate in the housing 1. The purpose of driving the rotor 3 to rotate is achieved through the pulley 10 and the belt 11 on the output shaft of the motor 7.

[0055] Among them, since the rotor 3 and the output shaft of the motor 7 are poweredly connected by the pulley 10 and the belt 11, the rotation direction of the rotor 3 is the same as the rotation direction of the output shaft of the motor 7, and the output shaft of the motor 7 and the support plate 5 are poweredly connected by the gear ring 9 and the gear 8, so the rotation direction of the output shaft of the motor 7 is opposite to the rotation direction of the support plate 5. In summary, the rotation direction of the support plate 5 is opposite to the rotation direction of the rotor 3.

[0056] Therefore, when the ore crushing device is in operation, when the rotor 3 drives the hammer 4 to strike the ore, the plate 6 throws the ore into the housing 1 in the direction opposite to the rotation direction of the hammer 4, so that the hammer 4 exerts a stronger impact on it.

[0057] In another specific embodiment:

[0058] The number of teeth of the gear ring 9 is at least twice that of the gear 8, and the diameters of the two pulleys 10 are the same, so that the rotation speed of the support plate 5 is lower than the rotation speed of the rotor 3, so as to avoid the plate 6 rotating too fast, resulting in the small ore that meets the standards after crushing being unable to pass through the gap between adjacent plates 6.

[0059] In another specific embodiment:

[0060] The cross section of the plate 6 is arc-shaped, one end of the arc-shaped structure extends along the radial direction of the support plate 5, and the rotation direction of the support plate 5 is opposite to the bending direction of the plate 6. This solution is conducive to shoveling up larger ores deposited on the screen 2.

[0061] In another specific embodiment:

[0062] A baffle 12 is provided at each end of the rotor 3 , and the two baffles 12 can completely cover the through hole in the middle of the support plate 5 . Both baffles 12 are located in the shell 1 . The baffles 12 are provided to prevent ore from flying out of the through hole in the middle of the support plate 5 .

[0063] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
