[0026] See also Figure 1-2As shown in Figure 5, the present invention is an ore mining, processing and screening equipment, including a frame 1, a rectangular frame 2 fixed on the frame 1 by an L-shaped connecting frame 15, and a screen assembly 3 movable left and right along a horizontal plane is arranged in the rectangular frame 2, and rectangular through holes 25 are respectively arranged on the two side walls of the rectangular frame 2. The two sides of the screen assembly 3 are connected with movable parts 24 located in the rectangular through holes 25 through connecting rods 27. When in use, the movable parts 24 move along the length direction of the rectangular through holes 25; and a plurality of supporting rollers 28 are synchronously installed between the two opposite inner walls of the rectangular frame 2, and the supporting rollers 28 are supported on the bottom side of the screen assembly 3.

[0027] In order to facilitate driving the screen assembly 3 to move inside the rectangular frame 2 during use, a motor 11 is installed on the frame 1, and a pulley B111 is fixed on the output shaft of the motor 11; the turntable 20 is rotatably installed on one side of the rectangular frame 2 through a rotating shaft, and a pulley A201 is arranged on one side of the turntable 20, and the pulley B111 and the pulley A201 are connected by a transmission belt, so that the motor 11 rotates to drive the turntable 20; and a fixed arm 21 is fixed at the center of the turntable 20, and the end of the fixed arm 21 is rotatably connected to a rotating arm 22, and the rotating arm 22 is rotatably connected to a connecting column 23, and the connecting column 23 is connected to the movable part 24. Based on the above arrangement, when in use, the transmission component composed of the rotating arm 22, the connecting column 23 and the fixed arm 21 is utilized to achieve the purpose of driving the movable part 24 to move along the length direction of the rectangular through hole 25.

[0028] Specifically, rectangular guide grooves are provided on both upper and lower sides of the movable member 24 , and guide slide bars 26 cooperating with the rectangular guide grooves are provided on two opposite inner walls of the rectangular through hole 25 .

[0029] In order to facilitate the collection of the materials screened by the screen 3, Figure 1 And 5-6, a U-shaped discharge chute A29 is fixed on the rectangular frame 2 located below the screen assembly 3, and a first material receiving box 51 / material conveyor belt A is placed directly below the discharge port of the U-shaped discharge chute A29; at the same time, in order to facilitate loading, a U-shaped frame 12 is arranged on the frame 1 located above the screen assembly 3, and a discharge chute 4 is fixed on the U-shaped frame 12, and the open end of the discharge chute 4 is connected to the hopper 13.

[0030] It can be known that in order to facilitate the restriction and blocking of the operation of the screen assembly 3, a stop rod 29 is installed between the two inner walls at one end of the rectangular frame 2, and the stop rod 29 includes a metal rod body and a rubber sleeve mounted on the outside of the metal rod body; during the rotation of the control motor 11, one end of the screen assembly 3 will collide with the stop rod 29, thereby causing the entire screen assembly 3 to vibrate violently, which will cause the particles adhering to the screen assembly 3 to fall off.

[0031] In a specific embodiment, Figure 3The screen assembly 3 provided by the invention comprises a pair of side plates 30, the two ends of the two side plates 30 are connected with a support beam A31, and a plurality of support beams B are connected between the two side plates 30 between the two support beams A31; a metal screen 32 is installed on the support beam A31 and the support beam B; a plurality of columns 34 are arranged on the support beam A31 away from one end of the discharge chute 4, a threaded structure is arranged at the end of the column 34, and a nut 35 is threadedly connected to the threaded structure; a baffle plate 33 is also included, and a through hole for the column 34 to pass through is arranged on the baffle plate 33; based on this arrangement, after a long period of screening, a large amount of large particles of debris will be enriched above the metal screen 32, and the presence of these large particles of debris will affect the screening efficiency of the screen assembly 3, Therefore, when in use, it is necessary to clean up the large particles of debris accumulated above the metal screen 32; when cleaning, loosen the nut 35, remove the baffle 33 at this time, and then control the activity of the screen assembly 3, so that the large particles of debris above the metal screen 32 can be cleaned out from the installation position of the baffle 33; in order to collect the large particles of debris cleaned out, a U-shaped unloading chute B4 is fixedly installed on the frame 1 located just below the end of the screen assembly 3 through an L-shaped angle iron 16; based on the above requirements, the metal screen 32 of the present invention is installed with an overall tilt setting, that is, when it is installed in use, the top protrusion heights of the two support beams A31 are different, and the height of the metal screen 32 gradually decreases from one end of the U-shaped frame 12 to the other end.

[0032] A U-shaped discharge chute C5 which moves forward and backward in the horizontal direction is arranged below the U-shaped discharge chute B4; when in use, when it is necessary to clean large particles of debris on the screen assembly 3, the U-shaped discharge chute C5 is controlled to move toward the inside of the frame 1, and then the top of the U-shaped discharge chute C5 is controlled to move out from the discharge port of the U-shaped discharge chute B4; when screening is performed, the U-shaped discharge chute C5 is controlled to move toward the outside of the frame 1, and then the top of the U-shaped discharge chute C5 is controlled to move to the discharge port of the U-shaped discharge chute B4. At this time, the material screened out from the screen assembly 3 enters the U-shaped discharge chute B4, and enters the U-shaped discharge chute C5 after being acted upon by the U-shaped discharge chute B4.

[0033] In order to facilitate the control of the U-shaped discharge chute C5 to move forward and backward in the horizontal direction, Figure 4 A pair of supporting side panels 10 are arranged on the frame 1, and a rectangular groove 101 is arranged on the opposite sides of the two supporting side panels 10 along the length direction thereof; a rectangular beam 50 matching the U-shaped unloading trough C5 is arranged on both sides of the U-shaped unloading trough C5; locking bolts 102 are arranged on the supporting side panels 10 to fix the rectangular beam 50 located in the U-shaped unloading trough C5.

[0034] In order to facilitate the collection of the large particles of debris cleared out during use, a second material collection box 40 / material conveyor belt B is placed just below the discharge port of the U-shaped discharge chute B4.
