[0042] Example 1

[0043] Reference Figure 1 - Figure 2 A schematic diagram of the overall structure of a coal conveyor belt for crushable coal is provided. The coal conveyor belt for crushable coal includes a coal conveying assembly 100, which includes a conveyor body 101 and a crushing component 102 disposed on one side of the conveyor body 101; and a screening assembly 200, which includes a structural component 201 disposed on one side of the crushing component 102, a actuating component 202 disposed on one side of the structural component 201, and a screening component 203 disposed on one side of the moving component 301.

[0044] The structural component 201 includes a screening box 201a disposed on one side of the crushing box 102a, a mounting column 201b disposed inside the screening box 201a, and a sliding column 201c slidably disposed on one side of the mounting column 201b.

[0045] The actuating component 202 includes a limiting frame 202a disposed on one side of the sliding column 201c, a limiting groove 202b opened on one side of the limiting frame 202a, and an elastic limiting block 202c rotatably disposed on one side of the limiting frame 202a. The screening component 203 includes a screening screen plate 203a disposed inside the screening box 201a. The screening screen plate 203a is used to screen the crushed coal.

[0046] Specifically, the crushing component 102 includes a crushing box 102a disposed on the upper side of the conveyor body 101, a feed inlet 102b disposed on the upper side of the crushing box 102a, a drive device 102c disposed on one side of the crushing box 102a, and a crushing cylinder 102d disposed inside the crushing box 102a. The crushing cylinder 102d is used to crush the coal raw material. The crushing box 102a is fixedly connected to the screening box 201a. The crushed coal in the crushing box 102a falls into the screening box 201a above the screening screen 203a. A door is opened on the other side of the screening box 201a. The coal remaining above the screening screen 203a after screening can be taken out and thrown back into the crushing box 102a for secondary crushing, thereby improving the crushing effect of the device on coal.

[0047] Furthermore, the structural component 201 also includes a support rod 201d disposed on one side of the screening box 201a, the support rod 201d being disposed on one side of the conveyor body 101, the structural component 201 also includes a support leg 201e disposed on one side of the mounting column 201b, and a mounting plate 201f disposed on one side of the mounting column 201b, the mounting plate 201f being used for fixing and splicing the mounting column 201b and for opening a through groove 201g on one side of the mounting column 201b, the sliding column 201c being disposed in the through groove 201g, the sliding column 201c being able to slide left and right in the through groove 201g.

[0048] Operation process: During use, the coal to be crushed is poured into the screening box 201a through the feed inlet 102b. Then, the drive device 102c is started, which drives the crushing cylinder 102d to rotate and crush the coal. The crushed coal falls onto the screening screen 203a in the screening box 201a and is screened by the screening screen 203a. The screened coal falls onto the conveyor body 101 and is conveyed by the conveyor body 101. At the same time, the coal remaining on the screening screen 203a can be removed and put back into the crushing box 102a for secondary crushing. This improves the crushing effect of the device on coal and reduces the inconvenience of existing conveyors that are difficult to crush before conveying and screen after crushing, resulting in excessive coal volume and mass above the conveyor, which affects the service life of the conveyor.

[0049] Example 2

[0050] Reference Figure 2 - Figure 6 This embodiment differs from the first embodiment in that: the actuating member 202 includes a drive motor 202d disposed on one side of the screening box 201a and an actuating plate 202e disposed on one side of the output end of the drive motor 202d. The actuating plate 202e is located inside the screening box 201a. When the drive motor 202d rotates, it drives the actuating plate 202e to rotate around the output shaft of the drive motor 202d. The actuating member 202 also includes an actuating rod 202f disposed on one side of the actuating plate 202e. When the actuating plate 202e rotates, it drives the actuating rod 202f to rotate.

[0051] The actuating element 202 includes a limiting frame 202a disposed on one side of the sliding column 201c, a limiting groove 202b opened on one side of the limiting frame 202a, and an elastic limiting block 202c rotatably disposed on one side of the limiting frame 202a. The elastic limiting block 202c has a reset elasticity, and its initial state is tilted to one side with one end in contact with one side of the limiting groove 202b. The actuating rod 202f extends into the limiting groove 202b.

[0052] Specifically, the actuating member 202 also includes an arc-shaped protrusion 202i disposed on one side of the elastic limiting block 202c and a smooth portion 202j disposed on one side of the elastic limiting block 202c. The arc-shaped protrusion is disposed at the upper and lower ends of the elastic limiting block 202c. The actuating member 202 also includes an arc-shaped portion 202k disposed on one side of the limiting groove 202b and a straight groove portion 202l disposed at both ends of the limiting groove 202b. The straight groove portion 202l is disposed at the upper and lower ends of the limiting groove 202b. In the initial state, the actuating rod 202f is located in the limiting groove 202b. When the actuating plate 202e drives the actuating rod 202f to rotate, the actuating rod 202f will rotate in the arc-shaped portion 202k of the limiting groove 202b. When it rotates to contact the arc-shaped protrusion 202i of the elastic limiting block 202c, it will squeeze the limiting block and make it move towards the initial state. When the lever 202f rotates in the opposite direction, it enters the straight groove 202l of the limiting groove 202b, thus losing the squeezing force on the elastic limiting block 202c. The elastic limiting block 202c returns to its initial tilted state. As the lever 202f continues to rotate, it drives the limiting frame 202a to move horizontally, thereby driving the sliding column 201c to move horizontally. When it reaches the end position, the lever 202f rotates to the arc-shaped part 202k on the other side of the limiting groove 202b, and rotates from the arc-shaped part 202k towards the arc-shaped protrusion 202i below the elastic limiting block 202c. Repeating the above steps, the limiting frame 202a and the sliding column 201c move horizontally in the opposite direction. This process is repeated to achieve the left and right sliding of the sliding column 201c.

[0053] Preferably, specifically, the actuating component 202 further includes an arc-shaped groove 202g opened on one side of the elastic limiting block 202c and a limiting post 202h set on one side of the limiting frame 202a. The limiting post 202h extends into the arc-shaped groove 202g. The arc-shaped groove 202g and the limiting post 202h are used to limit the elastic limiting block 202c and restrict its rotation angle. The screening component 203 includes a channel 203b opened on one side of the mounting post 201b, a connecting plate 203c set on one side of the sliding column 201c, and a screening screen plate 203a set on one side of the connecting plate 203c. During the left and right sliding of the sliding column 201c, the screening screen plate 203a is driven to shake left and right, thereby improving the screening effect of the device.

[0054] The rest of the structure is the same as in Example 1.

[0055] Operation process: When the crushed coal falls onto the upper side of the screening screen plate 203a, the drive motor 202d is started. The drive motor 202d rotates, driving the actuating plate 202e to rotate, which in turn drives the actuating rod 202f to rotate. When the actuating plate 202e drives the actuating rod 202f to rotate, the actuating rod 202f will rotate in the arc-shaped part 202k of the limiting groove 202b. When it rotates to contact the arc-shaped protrusion 202i of the elastic limiting block 202c, it will squeeze the limiting block and make it rotate in the opposite direction of the initial state. At this time, the actuating rod 202f rotates into the straight groove part 202l of the limiting groove 202b, and loses the squeezing force on the elastic limiting block 202c. The elastic limiting block 202c returns to its initial tilted state, and the actuating rod 202f rotates back to its initial position. As 2f continues to rotate, it will cause the limiting frame 202a to move horizontally, thereby causing the sliding column 201c to move horizontally. When it reaches the end position, the actuating rod 202f will rotate to the arc-shaped part 202k on the other side of the limiting groove 202b, and rotate from the arc-shaped part 202k towards the arc-shaped protrusion 202i below the elastic limiting block 202c. Repeat the above steps to cause the limiting frame 202a and the sliding column 201c to move horizontally in the opposite direction. During the process of the drive motor 202d driving the actuating plate 202e to rotate back and forth, the above process is repeated, thereby realizing the left and right sliding of the sliding column 201c, causing the screening screen plate 203a to shake left and right, thereby improving the screening effect of the device.

[0056] Example 3

[0057] Reference Figure 6 - Figure 8 This embodiment differs from the previous embodiments in that: the movable component 301 includes a movable block 301a disposed on one side of the sliding column 201c and a movable rod 301b disposed on one side of the movable block 301a. A strip-shaped groove is provided on the lower side of the mounting column 201b. One end of the movable block 301a extends into the strip-shaped groove and is connected to the sliding column 201c. When the sliding column 201c slides, it will drive the movable block 301a and the movable rod 301b to slide. The movable block 301a contacts one side of the mounting column 201b. The movable component 301 also includes a sliding groove 301c opened on one side of the mounting column 201b, a sliding block 301d slidably disposed in the sliding groove 301c, and a wedge 301e slidably disposed on one side of the sliding block 301d. The movable rod 301b contacts the horizontal surface of the wedge 301e. During the sliding process of the movable rod 301b, it can squeeze the wedge 301e, thereby driving the wedge 301e to slide.

[0058] Specifically, the movable component 301 also includes a stop block 301f disposed on one side of the mounting post 201b. The stop block 301f is used to block and compress the wedge block 301e, pressing it into the sliding block 301d. The movable rod 301b and the stop block 301f will never contact each other. A return spring 301g is disposed in the slide groove 301c. The two ends of the return spring 301g are connected to the inner side wall of the slide groove 301c and the side wall of the sliding block 301d, respectively. The return spring 301g is used to reset the sliding block 301d. The movable component 301 also includes a compression spring 301h disposed inside the sliding block 301d. The two ends of the compression spring 301h are connected to the side wall of the wedge block 301e and the inner side wall of the sliding block 301d, respectively. When the movable rod 301b slides, it drives the wedge block 301e to slide towards the stop block 301f. When the inclined surface of the slider 201c contacts the inclined surface of the stop block 301f, the stop block 301f will squeeze the wedge block 301e and press it into the sliding block 301d. At this time, the wedge block 301e separates from the moving rod 301b, and the sliding block 301d loses the squeezing force of the moving rod 301b. At this time, the slider is driven to return to its original sliding position by the rebound force of the return spring 301g. At the same time, during the sliding process, the wedge block 301e is extended again by the rebound force of the compression spring 301h. When the slider 201c slides in the opposite direction, when the moving rod 301b slides to contact the inclined surface of the wedge block 301e, it will slightly squeeze the wedge block 301e and press it into the sliding block 301d. After passing the wedge block 301e, the wedge block 301e extends again, and the moving rod 301b contacts the horizontal surface of the wedge block 301e again, returning to the initial state. This process is repeated to realize the left and right sliding of the sliding block 301d.

[0059] Furthermore, the striking element 302 includes a pressing rod 302a disposed on one side of the sliding block 301d and a pressing ball 302b disposed on one side of the pressing rod 302a. The pressing ball 302b is used to press the striking plate 302d. The striking element 302 also includes a fixing plate 302c disposed on one side of the mounting post 201b, a striking plate 302d slidably disposed on one side of the fixing plate 302c, and a striking block 302e disposed on one side of the striking plate 302d. The striking element 302 also includes a through hole 302f opened on one side of the fixing plate 302c and a through hole 302f disposed on the fixing plate 302c. The tension spring 302g on the inner side is used to reset the striking plate 302d. The extrusion ball 302b extends into the through hole 302f and slides therewith. During the sliding process, the sliding block 301d will drive the extrusion ball 302b to extend into the through hole 302f and extrude the striking plate 302d, thereby driving the striking plate 302d and the extrusion ball to slide upward and vibrate the upper screening screen plate 203a. On the one hand, this can improve the screening effect of the screening screen plate 203a on coal, and on the other hand, it can reduce the possibility of clogging of the screening screen plate 203a.

[0060] The rest of the structure is the same as in Example 2.

[0061] Operation process: As the sliding column 201c moves the screening screen 203a left and right, it also moves the wedge block 301e towards the stop block 301f. When the inclined surface of the wedge block 301e contacts the inclined surface of the stop block 301f, the stop block 301f will squeeze the wedge block 301e and press it into the sliding block 301d. At this time, the wedge block 301e separates from the moving rod 301b, and the sliding block 301d loses the squeezing force of the moving rod 301b. At this time, the slider is driven to return to its original position by the rebound force of the return spring 301g. At the same time, during the sliding process, the wedge block 301e is extended again by the rebound force of the compression spring 301h. At this time, the sliding column 201c slides to the end point on one side and begins to slide in the opposite direction. When the sliding column 201c slides in the opposite direction, the moving rod 301e... When rod 301b slides to contact the inclined surface of wedge 301e, it will slightly compress wedge 301e, pressing it into sliding block 301d, and then pass over wedge 301e. At this time, wedge 301e extends out again, and moving rod 301b contacts the horizontal surface of wedge 301e again, returning to the initial state. This process is repeated to achieve left and right sliding of sliding block 301d. During the reciprocating sliding of sliding block 301d, it will drive the extrusion ball 302b to intermittently extend into the through hole 302f to extrude the striking plate 302d, thereby driving the striking plate 302d and striking block 302e to slide upward, intermittently vibrating and striking the upper screening screen plate 203a. On the one hand, this can improve the screening effect of screening screen plate 203a on coal, and on the other hand, it can reduce the possibility of clogging of screening screen plate 203a.
