[0002] After the crusher in the mine crushes the ore, it needs to be screened. The ore that passes the screening will be sent to the subsequent work, and the unqualified ore will continue to be crushed.

[0003] A screening device produced by our company is a screen mesh with a well-shaped structure made of multiple steel bars, and the ore is screened by vibrating the screen mesh with a vibrator.

[0004] After the production of the screen is completed, it is necessary to test the strength of the screen, screening effect and other factors. The current testing method is to start the vibrator, then pour a car of ore of different sizes onto the screen, and then observe.

[0005] As far as the current testing method is concerned, the ore for testing needs to be loaded and unloaded repeatedly. However, the ore is large in size and heavy in weight, and the loading process is very slow, which seriously affects the overall testing efficiency. Utility Model Content

[0037] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Example:

[0039] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 This embodiment discloses a screening test device for a crusher, comprising a base 10, a conveyor belt 20, a lifting assembly 30, and a diversion trough 40. The base 10 is used to mount the screening equipment 50 to be tested, the conveyor belt 20 is used to transport the ore to be tested to the lifting assembly 30, and the lifting assembly 30 is used to lift the ore into the diversion trough 40. The diversion trough 40 is used to re-introduce the ore into the screening equipment 50 to achieve circulation.

[0040] Specifically, the top of the base 10 has a mounting area, and an output channel is provided in the middle of the mounting area of ​​the base 10. The output channel passes through the front side of the base 10. When the screening device 50 is installed, the screening device 50 is installed in the mounting area, and the bottom of the screening device 50 is located above the output channel.

[0041] A conveyor belt 20 is installed on two adjacent sides of the base 10. One conveyor belt 20 is located in front of the base 10 and docked at the outlet of the output channel. The other conveyor belt 20 is installed on the left side of the base 10 and below the outlet of the screening device 50. The two conveyor belts 20 are installed on the same horizontal plane, and one end of each conveyor belt 20 is close to each other.

[0042] The bottom of the lifting assembly 30 serves as its input end, communicating with the adjacent ends of the two conveyor belts 20, allowing ore output from both conveyor belts 20 to enter the lifting assembly 30. The top of the lifting assembly 30 serves as its output end, communicating with one end of a diversion trough 40. The diversion trough 40 is positioned above the base 10, with the end of the diversion trough 40 facing away from the lifting assembly 30 located directly above the base 10. The diversion trough 40 is arranged in a downwardly sloping direction.

[0043] In this embodiment, the screening device 50 to be tested is installed in the installation area of ​​the base 10, and then the entire device is driven to operate by the lifting assembly 30, and the entire screening device 50 is driven to operate by the vibrator on the screening device 50.

[0044] During the test, the test ore on the screening device 50 is screened and output from the output channel and the outlet of the screening device 50, and all the ores are respectively sent to the input end at the bottom of the lifting component 30 through two conveyor belts 20, and then all the ores are lifted into the guide trough 40 by the lifting component 30, and then sent to the screening device 50 again through the guide trough 40.

[0045] In the above-mentioned cycle work, a single screening device 50 can be tested for a long time to ensure the accuracy of the test. Through this technical solution, the ore loading process can be reduced, thereby shortening the working time of the entire test.

[0046] In one specific embodiment:

[0047] Vertical enclosures are located on the left, right, and rear sides of the installation area. The output channel extends from the center of the base 10 to the front of the installation area, and is arranged at an angle. This enclosure prevents ore from flying out of the left, right, and rear sides of the installation area. The inclined configuration of the output channel also facilitates ore removal.

[0048] In another specific embodiment:

[0049] A baffle 21 is provided on one side of the two conveyor belts 20 away from the base 10 to prevent ore from flying off the conveyor belts 20 .

[0050] In another specific embodiment:

[0051] The lifting assembly 30 includes a housing 31, a spiral column, and a motor 32. Specifically, the bottom of the housing 31 has two inlets on either side, connected to the output ends of the two conveyor belts 20, forming the input ends of the lifting assembly 30. The spiral column is rotatably mounted within the housing 31 and is arranged vertically, with one side of its top connected to one end of the guide trough 40. The output shaft of the motor 32 is connected to one end of the spiral column and is used to drive the spiral column to rotate.

[0052] In this embodiment, after the ore is fed from the conveyor belt 20 into the bottom of the outer shell 31, under the action of the motor 32, the spiral column will lift the ore upward in the outer shell 31, so that the ore reaches the end of the guide trough 40, and under the action of the guide trough 40, returns to the screening equipment 50.

[0053] Preferably, the spiral column includes a main shaft 35 and a spiral plate 34 provided on the main shaft 35, and one end of the main shaft 35 is connected to the output shaft of the motor 32. The pitch of the spiral plate 34 should be larger than the size of the largest ore.

[0054] In addition, one end of the guide groove 40 connected to the outer shell 31 has two arc-shaped plates 33, and the two arc-shaped plates 33 are both located above the spiral plate 34, one of the arc-shaped plates 33 is close to the main shaft 35, and the other is located on the outside of the spiral plate 34. The width between the two arc-shaped plates 33 is greater than or equal to the width of the spiral plate 34, and the two arc-shaped plates 33 form a bracket-shaped structure.

[0055] When the spiral plate 34 lifts the ore to the guide trough 40, as the spiral plate 34 continues to move, the ore enters the guide trough 40 under the action of the two arc-shaped plates 33. Since the guide trough 40 is arranged in an inclined structure, the ore in the guide trough 40 falls into the screening equipment 50 under the action of gravity.

[0056] Preferably, the housing 31 is hollow cylindrical in shape, with a receiving slot at its bottom. The slot has a semicircular shape at one end and two inlets at the other. The hollow cylindrical design of the housing 31 prevents ore from falling to the bottom. Therefore, the internal diameter of the housing 31 is slightly larger than the diameter of the spiral plate 34.

[0057] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
