[0043] Example 1

[0044] 1 and 2 , a schematic diagram of the overall structure of a coal conveyor belt conveyor capable of crushing coal is provided. The coal conveyor belt conveyor capable of crushing coal includes a coal conveying assembly 100, including a conveyor body 101 and a crushing member 102 disposed on one side of the conveyor body 101; a screening assembly 200, including a structural member 201 disposed on one side of the crushing member 102, a toggle member 202 disposed on one side of the structural member 201, and a screening member 203 disposed on one side of a moving member 301;

[0045] The structural member 201 includes a screening box 201a provided on one side of the crushing box 102a, a mounting post 201b provided inside the screening box 201a, and a sliding post 201c slidably provided on one side of the mounting post 201b;

[0046] The toggle member 202 includes a limit frame 202a arranged on one side of the slide column 201c, a limit groove 202b opened on one side of the limit frame 202a and an elastic limit block 202c rotatably arranged on one side of the limit frame 202a. The screening member 203 includes a screening mesh plate 203a arranged on the inner side of the screening box 201a. The screening mesh plate 203a is used to screen the crushed coal.

[0047] Specifically, the crushing part 102 includes a crushing box 102a arranged on the upper side of the conveyor body 101, a feed port 102b arranged on the upper side of the crushing box 102a, a driving device 102c arranged on one side of the crushing box 102a and a crushing cylinder 102d arranged 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 onto the screening mesh 203a in the screening box 201a. A box door is provided on the other side of the screening box 201a. The coal remaining above the screening mesh 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 the coal.

[0048] Furthermore, the structural component 201 also includes a support rod 201d arranged on one side of the screening box 201a, and the support rod 201d is arranged on one side of the conveyor body 101. The structural component 201 also includes a support leg 201e arranged on one side of the mounting column 201b, and a mounting plate 201f arranged on one side of the mounting column 201b. The mounting plate 201f is used to fix and splice the mounting column 201b and a through groove 201g opened on one side of the mounting column 201b. The sliding column 201c is arranged in the through groove 201g, and the sliding column 201c can slide left and right in the through groove 201g.

[0049] Operation process: When in use, the coal to be crushed is poured into the screening box 201a through the feed port 102b, and the driving device 102c is started to drive the crushing cylinder 102d to rotate to crush the coal. The crushed coal falls onto the screening mesh plate 203a in the screening box 201a, and the coal is screened by the screening mesh plate 203a. The screened coal falls onto the conveyor body 101 and is transported by the conveyor body 101. At the same time, the coal remaining above the screening mesh plate 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 coal by the device and reducing the inconvenience of the existing conveyor that is difficult to crush the coal before transportation and screen the crushed coal, resulting in the volume and mass of the coal above the conveyor being too large, making the mass of the coal above the conveyor per unit area too large, thereby affecting the service life of the conveyor.

[0050] Example 2

[0051] 2 to 6 , this embodiment differs from the first embodiment in that the toggle member 202 includes a drive motor 202d disposed on one side of the screening box 201a and a toggle plate 202e disposed on one side of the output end of the drive motor 202d. The toggle plate 202e is located in the screening box 201a. When the drive motor 202d rotates, the toggle plate 202e is driven to rotate with the output shaft of the drive motor 202d as the center. The toggle member 202 also includes a toggle rod 202f disposed on one side of the toggle plate 202e, which drives the toggle rod 202f to rotate when the toggle plate 202e rotates.

[0052] The toggle member 202 includes a limit frame 202a arranged on one side of the sliding column 201c, a limit slot 202b opened on one side of the limit frame 202a and an elastic limit block 202c rotatably arranged on one side of the limit frame 202a. The elastic limit block 202c has reset elasticity, and its initial state is tilted to one side and one end of it is in contact with one side of the limit slot 202b. The toggle rod 202f extends into the limit slot 202b.

[0053] Specifically, the toggle member 202 further includes an arc-shaped protrusion 202i provided on one side of the elastic limiting block 202c and a smooth portion 202j provided on one side of the elastic limiting block 202c. The arc-shaped protrusion is provided at the upper and lower ends of the elastic limiting block 202c. The toggle member 202 further includes an arc-shaped portion 202k provided on one side of the limiting groove 202b and a straight groove portion 202l provided at both ends of the limiting groove 202b. The straight groove portion 202l is provided at the upper and lower ends of the limiting groove 202b. In the initial state, the toggle rod 202f is located in the limiting groove 202b. When the toggle plate 202e drives the toggle rod 202f to rotate, the toggle 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 to make it rotate in the opposite direction of the initial state. At this time, the toggle rod 202f rotates into the straight groove portion 202l of the limit groove 202b, and the squeezing force on the elastic limit block 202c is lost. The elastic limit block 202c resumes its tilt to its initial state. When the toggle rod 202f continues to rotate, it will drive the limit frame 202a to move horizontally, thereby driving the sliding column 201c to move horizontally. When it moves to the end position, the toggle rod 202f will rotate to the arc portion 202k on the other side of the limit groove 202b, and rotate from the arc portion 202k toward the arc-shaped protrusion 202i below the elastic limit block 202c. Repeat the above steps to drive the limit frame 202a and the sliding column 201c to move horizontally in the opposite direction, and so on, thereby realizing the left and right sliding of the sliding column 201c.

[0054] Preferably, specifically, the toggle member 202 also includes an arcuate groove 202g opened on one side of the elastic limit block 202c and a limit column 202h arranged on one side of the limit frame 202a, and the limit column 202h extends into the arcuate groove 202g. The arcuate groove 202g and the limit column 202h are used to limit the elastic limit block 202c and limit its rotation angle. The screening member 203 includes a groove 203b opened on one side of the mounting column 201b, a connecting plate 203c arranged on one side of the sliding column 201c and a screening mesh plate 203a arranged on one side of the connecting plate 203c. During the process of the sliding column 201c sliding left and right, the screening mesh plate 203a is driven to shake left and right, thereby improving the screening effect of the device.

[0055] The rest of the structure is the same as that of Example 1.

[0056] Operation process: When the crushed coal blocks fall onto the upper side of the screening mesh plate 203a, the driving motor 202d is started, and the driving motor 202d rotates to drive the toggle plate 202e to rotate, thereby driving the toggle rod 202f to rotate. When the toggle plate 202e drives the toggle rod 202f to rotate, the toggle rod 202f will rotate in the arc 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 to rotate in the opposite direction of the initial state. At this time, the toggle rod 202f rotates into the straight groove portion 202l of the limiting groove 202b. At this time, the squeezing force on the elastic limiting block 202c is lost, and the elastic limiting block 202c resumes its tilt to the initial state, and the toggle rod 20 When 2f continues to rotate, the limit frame 202a will be driven to move horizontally, thereby driving the sliding column 201c to move horizontally. When it moves to the end position, the toggle rod 202f will rotate to the arc portion 202k on the other side of the limit slot 202b, and rotate from the arc portion 202k toward the arc-shaped protrusion 202i below the elastic limit block 202c. Repeat the above steps to drive the limit frame 202a and the sliding column 201c to move horizontally in the opposite direction. In the process of the driving motor 202d driving the toggle plate 202e to rotate back and forth, the above process is repeated, thereby realizing the left and right sliding of the sliding column 201c, driving the screening mesh plate 203a to shake left and right, thereby improving the screening effect of the device.

At this time, the wedge block 301e is separated 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 by the rebound force of the return spring 301g to return to its original position. 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 sliding column 201c slides in the opposite direction, the moving rod 301b slides to the inclined surface of the wedge block 301e, which will slightly squeeze the wedge block 301e and press it into the sliding block 301d, then pass over the wedge block 301e. At this time, the wedge block 301e is extended again, and the moving rod 301b contacts the horizontal surface of the wedge block 301e again, returning to the initial state, and so on, realizing the left and right sliding of the sliding block 301d.
