Description

Technical Field

[0001] The invention relates to the technical field of dry coal sorting, in particular to a flap-type dry coal sorting equipment. Background Art

[0002] In the field of coal sorting technology, dry sorting is a commonly used sorting method. Its basic principle is to analyze the moving material through rays to determine whether the material in the unit area is coal or gangue and other impurities, and then calculate the time it takes to pass through the pneumatic actuator through kinematics, and then control the opening and closing of the corresponding valve on the pneumatic actuator to remove the gangue impurities in the coal, thereby completing the sorting process.

[0003] When coal is sorted, there is still a certain amount of moisture on the surface of the coal. Due to friction, collision, extrusion and other effects during sorting, some of the moisture will be separated, which not only changes the moisture content of the coal, but also increases the adhesion between the coal and the inner wall of the sorting equipment during sorting. Since coal sorting is a continuous working process, it is difficult for cleaning personnel to clean the adhered coal in time. In the long run, it will cause the distribution of coal in the equipment and its fluidity when falling, resulting in the coal not being able to fall according to the expected trajectory and speed, thereby affecting the sorting effect. Summary of the invention

A flap-type coal delivery trolley is provided, and the bottom of the trolley can be flipped. The bottom of the trolley and its side are connected by a controllable locking structure.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] Embodiment 1:

[0043] See also Figures 1 to 5 A flap-type dry coal sorting equipment comprises a frame 1, a driving device 2 fixedly mounted on the frame 1, an identification and sorting device 3 mounted above the driving device 2, and a control device 4 arranged on the frame 1 and located below the sorting device 3. A plurality of sorting channels 5 are arranged on one side of the frame 1, and a coal delivery device 6 is fixedly connected to the driving device 2.

[0044] A second step skateboard 11 is installed at the upper end of the frame 1 and at a position located on one side of the coal delivery device 6. The upper end of the second step skateboard 11 is fixedly connected to the end of the coal delivery device 6. The upper end surfaces of the second step skateboard 11 and the first step skateboard 12 are both composed of inclined surfaces and planes. A plurality of correcting wheels 13 are installed at the upper end of the frame 1 and at a position located on the inner side of the identification and sorting device 3.

[0045] The driving device 2 includes a power shaft 23, and the power shafts 23 are symmetrically installed at both ends of the frame 1, and the end of the power shaft 23 on one side is connected to a reducer 22, and the input end of the reducer 22 is connected to the output shaft of the driving motor 21, and the driving motor 21 is fixedly installed on the side wall of the frame 1. Sprockets 24 are symmetrically installed on the power shaft 23, and a transmission chain 25 is wound around the sprocket 24. Support rails 26 are symmetrically arranged on both sides of the transmission chain 25. The support rails 26 and the guide wheels 61 are in sliding contact. The ends of the support rails 26 are arc-shaped and oil leakage holes 261 are opened on the opposite side walls. A lubrication component 27 is arranged in the middle of the power shaft 23 near the driving motor 21.

[0046] The lubrication assembly 27 includes an I-shaped sleeve 271, which is fixedly installed on the middle part of the power shaft 23 near the drive motor 21. A connecting disk 272 is sleeved on the outside of the I-shaped sleeve 271. The connecting disk 272 is fixedly connected to the I-shaped sleeve 271 by fixing bolts 273. The side wall of the connecting disk 272 is evenly provided with oil cylinders 274 along its circumference. A piston plate 276 is slidably installed inside the oil cylinder 274 through a supporting spring 275. A ball head rod 277 is fixedly connected to the middle part of the piston plate 276.

Under the synchronous rotation of the transmission chain 25, the coal delivery device 6 together with the coal will move along the rotation direction of the transmission chain 25. When the coal delivery device 6 moves to the bottom of the sorting device 3, the sorting device 3 can analyze the coal through rays, so as to determine whether the coal in the coal delivery device 6 is coal or gangue, and then calculate the time it takes to reach the pneumatic actuator through kinematics and transmit the signal to the control device 4. The control device 4 can control the operation of the pneumatic actuator. After identification and sorting, the coal will continue to move along the rotation direction of the transmission chain 25.

[0049] Embodiment 2:

[0050] The technical solution is basically the same as that of the first embodiment, see Figure 1 , Figure 2 , Figures 6 to 9 as well as Fig.11 , the difference is:

[0051] The coal conveying device 6 includes a guide wheel 61, and a guide wheel 61 is slidably provided on the upper end of the driving device 2. The guide wheel 61 is arranged through the middle part of the lower end of the L-shaped frame plate 62, and the L-shaped frame plate 62 is fixedly connected to the driving device 2. A side support plate 63 is fixedly connected to the upper end of the L-shaped frame plate 62. The cross-section of the side support plate 63 is triangular, and the inclined surfaces of the two side support plates 63 are arranged opposite to each other. A surrounding plate 64 is fixedly installed on the side wall of the end of the side support plate 63, and a bottom plate 65 is arranged at the lower end of the opposite side of the side support plate 63. A coal storage space is formed between the bottom plate 65, the surrounding plate 64 and the side support plate 63. A rotating shaft 66 is fixedly installed on the end of the bottom plate 65 near the surrounding plate 64, and the rotating shaft 66 and the surrounding plate 64 are rotatably connected. A support column 67 is fixedly installed on the side wall of the end of the bottom plate 65 away from the surrounding plate 64, and a limit assembly 68 is arranged at a position near the support column 67 on the lower end surface of the side support plate 63, and the limit assembly 68 and the support column 67 are connected in cooperation.

[0052] Buffer wheels 651 are symmetrically mounted on the lower end surface of the bottom plate 65 near the edge.

[0053] The limiting assembly 68 includes a limiting plate 681, and the bottom of the side support plate 63 is ball-jointed to the limiting plate 681. A rectangular groove 682 is provided in the middle of the upper end of the limiting plate 681, and a cross plate 683 is inserted in the rectangular groove 682. A hinge 684 is fixedly connected to the side wall of the cross plate 683. A torsion spring is provided in the middle of the hinge 684 and its upper end is fixedly installed on the bottom of the side support plate 63. A concave groove 685 is provided on the side wall of the limiting plate 681 close to the support column 67, and the support column 67 abuts in the concave groove 685. The central angle of the concave groove 685 is less than 180 degrees. A positioning groove 686 is provided on the side wall of the cross plate 683, and an electric push rod 688 is installed on the side wall of the side support plate 63. The protruding end of the electric push rod 688 is fixedly connected to a convex magnetic plate 687, and the convex magnetic plate 687 is opposite to the positioning groove 686.

[0054] In this embodiment, the horizontal plate 683 is made of magnetic material and can limit and fix the limiting plate 681 under the action of the convex magnetic plate 687.

[0055] During specific operation, when the coal delivery device 6 moves to the predetermined sorting channel 5, the electric push rod 688 is started, and the convex magnetic plate 687 is driven by the electric push rod 688 to separate from the cross plate 683. At this time, the cross plate 683 and the hinge 684 can rotate freely, and the gravity of the coal will squeeze the support column 67, so that the bottom plate 65 rotates downward around the rotating shaft 66, and the support column 67 will squeeze the limit plate 681, so that the limit plate 681 rotates a certain angle around the ball hinge point and resets under the action of the torsion spring. Finally, the bottom plate 65 rotates to the bottom of the limit plate 681, and the coal on the bottom plate 65 falls along the sorting channel 5. When the gangue in the coal moves to the top of the pneumatic actuator, the control device 4 will control the pneumatic actuator to open and remove the gangue.

[0056] Embodiment three:

[0057] The technical solution is basically the same as that of the second embodiment, see Figure 1 , Figure 2 , Figures 6 to 9 as well as Fig.10 , the difference is that: the central angle corresponding to the concave groove 685 is greater than 180 degrees.

[0058] During operation, the electric push rod 688 is started, and the convex magnetic plate 687 is driven to separate from the horizontal plate 683 by the electric push rod 688. At this time, since the central angle of the concave groove 685 is greater than 180 degrees, the pressure of the coal material alone cannot make the limit plate 681 rotate, and the driving device 2 will drive the coal delivery device 6 to continue to move along the support track 26. When the lower end of the limit plate 681 contacts the first step slide plate 12, due to the obstruction of the first step slide plate 12, the limit plate 681 will deflect at a certain angle. At this time, the gravity of the coal material will drive the bottom plate 65 to rotate to the limit plate 6 81, the coal above the bottom plate 65 will slide down along the bottom plate 65 into the sorting channel 5. When the gangue in the coal moves to the top of the pneumatic actuator, the control device 4 will control the pneumatic actuator to open and remove the gangue. The buffer wheel 651 set at the lower end of the bottom plate 65 can generate a certain shock force when it hits the first step slide plate 12. Then the buffer wheel 651 will hit the second step slide plate 11, and the bottom plate 65 will continue to rotate downward at a certain angle. The shock force generated by the two collisions can accelerate the falling speed of the coal above the bottom plate 65, thereby improving the coal sorting efficiency.

[0059] When the coal material above the bottom plate 65 has finished falling, the entire coal delivery device 6 will continue to move along the rotation direction of the transmission chain 25. When the bottom plate 65 moves to above the lubrication assembly 27, the bottom plate 65 will hit the ball head rod 277. The impact force can cause the bottom plate 65 to vibrate again, thereby shaking off a small amount of wet coal adhering to its surface. At the same time, the ball head rod 277 will move into the oil cylinder 274 and squeeze the piston plate 276. At this time, the support spring 275 is compressed, and the lubricating oil in the oil cylinder 274 will be squeezed to the atomizing nozzle 279 through the oil pipe 278, and then sprayed out through the atomizing nozzle 279. The end of the support rail 26 is arc-shaped and an oil leakage hole 261 is opened on the opposite side wall, so the atomized lubricating oil can adhere to the meshing point of the sprocket 24 and the transmission chain 25, and at the same time adhere to the contact point between the guide wheel 61 and the support rail 26, so that it can play a lubricating role, which is conducive to the stable operation of the entire coal delivery device 6. When the lubricating oil in the previous oil cylinder 274 is used up, the fixing bolt 273 can be manually unscrewed and the connecting plate 272 can be rotated a certain angle, so that the next oil cylinder 274 can be adjusted to a position that can contact the bottom plate 65, and finally the fixing bolt 273 is screwed back;

[0060] After passing through the lubrication component 27, the bottom plate 65 will continue to move along the support track 26 below. During this process, natural wind can blow on the surface of the bottom plate 65 to keep it dry. Then the bottom plate 65 moves to the top of the end away from the lubrication component 27. Due to the existence of the correcting wheel 13, the correcting wheel 13 can support the bottom plate 65 while correcting the bottom plate 65, so that the bottom plate 65 rotates upward around the rotating shaft 66 and gradually squeezes the limit plate 681. At this time, the limit plate 681 will rotate to a certain extent. Finally, the bottom plate 65 drives the support column 67 to move into the concave groove 685 again, and the electric push rod 688 will drive the convex magnetic plate 687 to abut against the positioning groove 686 on the cross plate 683, so as to achieve the purpose of limiting and fixing the limit plate 681. At this time, the bottom plate 65 will also be fixed, and coal can be added again manually to carry out the next coal sorting operation.

[0061] The working principle of the present invention when in use:

[0062] 1. In the initial position, the coal delivery device 6 is located near the end of the sorting device 3. At this time, the coal to be sorted is manually added to the coal delivery device 6. The support rail 26 can play a certain supporting role for the coal delivery device 6. The drive motor 21 is started. Under the deceleration transmission of the reducer 22, the drive motor 21 will drive the power shaft 23 and the sprocket 24 to rotate. Under the synchronous rotation of the transmission chain 25, the coal delivery device 6 together with the coal will move along the rotation direction of the transmission chain 25. When the coal delivery device 6 moves to the bottom of the sorting device 3, the sorting device 3 can analyze the coal through rays, so as to determine whether the coal in the coal delivery device 6 is coal or gangue. Then, the time for it to reach the pneumatic actuator is calculated through kinematics and the signal is transmitted to the control device 4. The control device 4 can control the operation of the pneumatic actuator. After identification and sorting, the coal will continue to move along the rotation direction of the transmission chain 25.

[0063] Second: If the central angle of the concave groove 685 is less than 180 degrees, when the coal delivery device 6 moves to the predetermined sorting channel 5, the electric push rod 688 is started, and the convex magnetic plate 687 is driven by the electric push rod 688 to separate from the horizontal plate 683. At this time, the horizontal plate 683 and the hinge 684 can rotate freely, and the gravity of the coal will squeeze the support column 67, so that the bottom plate 65 rotates downward around the rotating shaft 66, and the support column 67 will squeeze the limit plate 681, so that the limit plate 681 rotates a certain angle around the ball hinge point and resets under the action of the torsion spring. Finally, the bottom plate 65 rotates to the bottom of the limit plate 681, and the coal on the bottom plate 65 falls along the sorting channel 5. When the gangue in the coal moves to the top of the pneumatic actuator, the control device 4 will control the pneumatic actuator to open and remove the gangue;

[0064] 3. If the central angle of the concave groove 685 is greater than 180 degrees, the electric push rod 688 is started, and the convex magnetic plate 687 is driven to separate from the horizontal plate 683 by the electric push rod 688. At this time, since the central angle of the concave groove 685 is greater than 180 degrees, the pressure of the coal material alone cannot make the limit plate 681 rotate, and the driving device 2 will drive the coal delivery device 6 to continue to move along the support track 26. When the lower end of the limit plate 681 contacts the first step slide plate 12, due to the obstruction of the first step slide plate 12, the limit plate 681 will deflect at a certain angle, and the gravity of the coal material will drive the bottom plate 6 5 rotates to the bottom of the limit plate 681, and the coal above the bottom plate 65 will slide down along the bottom plate 65 into the sorting channel 5. When the gangue in the coal moves to the top of the pneumatic actuator, the control device 4 will control the pneumatic actuator to open and remove the gangue. The buffer wheel 651 set at the lower end of the bottom plate 65 can generate a certain shock force when it hits the first step slide plate 12, and then the buffer wheel 651 will hit the second step slide plate 11, and the bottom plate 65 will continue to rotate downward by a certain angle. The shock force generated by the two collisions can accelerate the falling speed of the coal above the bottom plate 65, thereby improving the coal sorting efficiency;

[0065] Fourth: When the coal material above the bottom plate 65 has finished falling, the entire coal delivery device 6 will continue to move along the rotation direction of the transmission chain 25. When the bottom plate 65 moves to above the lubrication assembly 27, the bottom plate 65 will hit the ball head rod 277. The impact force can cause the bottom plate 65 to vibrate again, thereby shaking off a small amount of wet coal adhering to its surface. At the same time, the ball head rod 277 will move into the oil cylinder 274 and squeeze the piston plate 276. At this time, the support spring 275 is compressed, and the lubricating oil in the oil cylinder 274 will be squeezed to the atomizing nozzle 279 through the oil pipe 278, and then sprayed out through the atomizing nozzle 279. The end of the support rail 26 is arc-shaped and an oil leakage hole 261 is opened on the opposite side wall, so that the atomized lubricating oil can adhere to the meshing point of the sprocket 24 and the transmission chain 25, and at the same time adhere to the contact point between the guide wheel 61 and the support rail 26, so that it can play a lubricating role, which is conducive to the stable operation of the entire coal delivery device 6. When the lubricating oil in the previous oil cylinder 274 is used up, the fixing bolt 273 can be manually unscrewed and the connecting plate 272 can be rotated a certain angle, so that the next oil cylinder 274 can be adjusted to a position that can contact the bottom plate 65, and finally the fixing bolt 273 is screwed back;

[0066] 5: After passing through the lubrication component 27, the bottom plate 65 will continue to move along the support track 26 below. During this process, natural wind can blow on the surface of the bottom plate 65 to keep it dry. Then the bottom plate 65 moves to the top of the end away from the lubrication component 27. Due to the existence of the correcting wheel 13, the correcting wheel 13 can support the bottom plate 65 while correcting it, so that the bottom plate 65 rotates upward around the rotating shaft 66 and gradually squeezes the limit plate 681. At this time, the limit plate 681 will rotate to a certain extent. Finally, the bottom plate 65 drives the support column 67 to move into the concave groove 685 again, and the electric push rod 688 will drive the convex magnetic plate 687 to abut against the positioning groove 686 on the cross plate 683, so as to achieve the purpose of limiting and fixing the limit plate 681. At this time, the bottom plate 65 will also be fixed, and coal can be added again manually to carry out the next coal sorting operation.
