[0003] Currently, limestone, as a raw material for cement production, is often transported using conveying equipment with dust-proof effect. Since the surface of limestone particles is relatively rough and irregular in shape, the sharp edges rub against the surface of the conveying equipment, increasing wear.

[0017] 1. When it is necessary to transport limestone, the raw material for cement production, the chain conveyor device is first started. When the slide plate moves to the bottom of the storage bin, the slide plate is pushed by the storage bin to open the conveying box.

[0018] 2. When the conveying box filled with limestone moves to one end of the chain conveyor, the drive motor is started to drive the protrusion to rotate, which in turn drives multiple protrusions of different lengths to push the slide plate upward, so that the limestone placed in the conveying box falls downward to the inside of the collecting bin under the action of its own gravity, thus completing the conveying of the limestone. The automatic unloading of the limestone is realized through the action of the pushing component, further improving the conveying efficiency of the dust-proof conveying equipment.

The outer surface of the baffle 406 is slidably connected to the inner wall of the slide groove 402. A pressure sensor 407 is provided on the outer surface of the other side of the storage bin 401 near the bottom.

[0039] In this embodiment, during the cement production process, when it is necessary to transport the raw material limestone for cement production, the chain conveyor 2 is first started, wherein the chain conveyor 2 is composed of a chain, a sprocket, a tray and a driving device, the chain is connected by the sprocket and moves on a certain track, the operation of the chain conveyor 2 drives a plurality of relatively arranged connecting blocks 501 to move along the rotation of the two chains, and then drives a plurality of conveying boxes 503 to move, and the chain conveyor 2 is connected to the plurality of relatively arranged connecting blocks 501 to move along the rotation of the two chains, and then drives a plurality of conveying boxes 503 to move, and the chain conveyor 2 is connected to the plurality of relatively arranged connecting blocks 501 to move along the rotation of the two chains, and then drives a plurality of relatively arranged connecting blocks 501 to move, and the chain conveyor 2 is connected to the ... Figure 2 and Figure 5 As shown, the movement of the conveying box 503 drives the L-shaped slide plate 505 to move. When the slide plate 505 moves to the bottom of the storage bin 401, since the top of the slide plate 505 is higher than the bottom of the storage bin 401 and lower than the bottom of the baffle 406, when the conveying box 503 continues to move toward the storage bin 401, the slide plate 505 is pushed by the storage bin 401 and moves toward the mounting frame 506, thereby causing the two first springs 508 to be squeezed and shortened, so that the conveying box 503 is opened. At the same time, when the slide plate 505 moves to the bottom of the storage bin 401, the first air pump 513 is started, and the first valve 514 on the surface of the air inlet pipe is opened to push the air into the hollow tube 510. The internal gas is transported, thereby driving the first piston 511 to move in the direction of the push rod 512 until the push rod 512 is extended to its longest position. When the outer surface of the slide plate 505 contacts the outer surface of the storage bin 401, the outer surface of the push rod 512 just contacts the outer surface of the baffle 406, and pushes the baffle 406 outward along the movement of the conveying box 503, so that the two second springs 405 connected thereto are squeezed and shortened, thereby causing a gap between the baffle 406 and the inside of the storage bin 401, so that the limestone in the conveying box 503 falls downward into the inside of the conveying box 503 under the action of its own gravity. When the outer surface of the hollow tube 510 moves to contact the outer surface of the storage bin 401, as shown in FIG. Figure 7As shown, since the outer diameter of the hollow tube 510 is greater than the outer diameter of the push rod 512, when the hollow tube 510 moves to the outer surface of the storage bin 401, it just contacts the pressure sensor 407. The pressure sensor 407 uses a resistance strain gauge. The pressure acts on the measuring diaphragm of the sensor, causing the diaphragm to deform, thereby causing the resistance of the strain gauge to change. By measuring the resistance change, the applied pressure can be calculated using the corresponding conversion relationship. When the pressure sensor 407 detects the external pressure, the signal is transmitted to the external control system. The first air pump 513 is started again through the external control system, and the first valve 514 on the surface of the air intake pipe is opened to extract gas into the interior of the hollow tube 510, so that the interior of the hollow tube 510 is in a negative pressure state, and then the first piston 511 moves toward the direction of the first air pump 513 under the action of the negative pressure, and then drives the push rod 512 to move toward the direction of the first air pump 513, so that the push rod 512 is separated from the baffle 406, and the two second springs 405 can be extended under the action of their own elastic force, thereby driving the baffle 406. The bottom of the storage bin 401 is sealed by resetting. At this time, the two cylinders 502 matching the conveying box 503 are started through the external control system to shorten it, drive the conveying box 503 to move downward, thereby driving the slide plate 505 to move downward and separate it from the outer surface of the storage bin 401, so that the two first springs 508 are no longer squeezed and extend under the action of their own elastic force, thereby driving the slide plate 505 to move in the direction away from the mounting frame 506 until it contacts the inner wall of the conveying box 503, that is, the sealing of the conveying box 503 is completed to prevent dust from flying inside the limestone during the transportation process. While the conveying box 503 is sealed, it continues to move forward with the chain conveyor 2 to transport the limestone. Since the limestone is relatively stationary with the conveying box 503 during the transportation process, it will not cause excessive friction to the inside of the conveying box 503, thereby reducing the wear of the conveying equipment due to sliding friction, solving the problem of the traditional conveying method of conveying limestone, a raw material for cement production, which is easy to wear the conveying equipment and reduces the service life of the conveying equipment in the prior art.

[0041] In this embodiment, when the conveying box 503 filled with limestone moves to one end of the chain conveyor 2, the distance between the slide plate 505 and the protrusion 610 is first detected by the photoelectric sensor 611, wherein the photoelectric sensor 611 mainly emits a laser beam, and the beam is reflected back after irradiating the target object. The sensor measures the time difference from the emission to the reception of the laser, and calculates the distance between the object and the sensor by the speed of light. When the slide plate 505 moves to the longest protrusion close to the protrusion 610, the drive motor 606 is started by the external control system to drive the protrusion 610 to rotate clockwise, thereby driving multiple protrusions of different lengths on the protrusion 610 to rotate. During the rotation of the protrusion 610, the coil spring 609 is stretched and elongated, and the rotation of the protrusion 610 causes it to exert an upward thrust on the slide plate 505. Figure 2 and Figure 3 As shown, when the slide plate 505 moves to a position close to the protrusion 610, it will move along an arc driven by the chain conveyor 2, as shown in FIG. Fig. 9 As shown, the raised portion on the surface of the protrusion 610 becomes shorter in clockwise order along the longest protrusion, and the shortened length matches the distance from the center position of the protrusion 610 when the slide plate 505 rotates downward along the arc. As the protrusion 610 rotates, the slide plate 505 is continuously pushed upward, so that the two first springs 508 are squeezed and shortened. As the slide plate 505 rotates downward and opens, the limestone placed in the conveying box 503 falls downward to the inside of the collecting bin 701 under the action of its own gravity, and the conveying of the limestone is completed. When the photoelectric sensor 611 detects that the shortest raised portion on the surface of the protrusion 610 rotates to contact the outer surface of the slide plate 505, the signal is transmitted to the external control system, and the two electric push rods 604 are activated by the control system to shorten them. When the movable protrusion 610 moves to a position away from the slide plate 505, the driving motor 606 can be turned off. Among them, the driving motor 606 is not arranged with a self-locking function. When the driving motor 606 is turned off, the coil spring 609 will shorten under the action of its own elastic force, thereby driving the protrusion 610 to rotate in the opposite direction and reset. When the automatic feeding component 5 moves to the bottom of the chain conveyor 2, the first air pump 513 on the automatic feeding component 5 is started again to transport gas to the inside of the hollow tube 510, driving the push rod 512 to extend to its longest length, and at the same time, the two cylinders 502 on the automatic feeding component 5 are started to stretch them, driving the conveying box 503 to move away from the chain conveyor 2. The automatic unloading of limestone is realized by the action of the pushing component 6, and the conveying efficiency of the dust-proof conveying equipment is further improved.

[0042] Embodiment 3: Figure 1-2 and Figure 11-15As shown, the dustproof component 7 includes a collecting bin 701, the bottom of the collecting bin 701 is fixedly connected to the top of the base plate 1, the opposite inner walls of the collecting bin 701 are provided with grooves 702, the inner walls of the two grooves 702 are fixed with connecting rods 703, the outer surfaces of the two connecting rods 703 are provided with fans 704, the outer surfaces of the two grooves 702 are fixedly installed with leak hole blocks 705, two temporary storage boxes 707 are fixed to the top of the base plate 1, the outer surfaces of the two temporary storage boxes 707 are fixedly connected with conveying pipes 706, one ends of the two conveying pipes 706 are respectively fixedly passed through the interiors of the two grooves 702, and exhaust valves 708 are provided on the tops of the two temporary storage boxes 707.

[0043] In this embodiment, when limestone for cement production is transported to the interior of the collection bin 701, in order to prevent dust in the limestone from polluting the air during the falling process, when the transport box 503 moves to the top of the collection bin 701, the second air pump 715 is first started, and the second valve 716 on the surface of the air inlet pipe is opened to transport gas to the interior of the air delivery pipe 717, so that the interior of the four hollow rods 712 is filled with gas, and then the four second pistons 714 move upward under the action of air pressure, thereby driving the four lifting pipes 713 to move upward, thereby driving the lifting frame 710 to move upward, and then the telescopic sleeve 709 The two fans 704 are respectively started to absorb gas from the outside, so that the inside of the collection bin 701 is in a negative pressure state, and the dust moving downward is moved to the inside of the two conveying pipes 706 under the action of the negative pressure. The fans 704 are mainly based on the principles of gas dynamics and the basic laws of air flow. The fans 704 rotate mechanically to drive the impeller to rotate. The high-speed rotation of the impeller causes the surrounding air to be sucked in. When the impeller of the fan 704 rotates, the air is compressed and pushed to the outlet. Since the volume of the gas decreases in the process of being sucked into the impeller, the pressure of the gas decreases, forming a negative pressure. In order to prevent large particles of limestone from falling into the two conveying pipes 706, the two leak blockers 705 are used to effectively protect the two fans 704. After the dust enters the two temporary storage boxes 707 along the two conveying pipes 706, the two exhaust valves 708 are opened, so that the gas entering the temporary storage box 707 is discharged outward along the exhaust valves 708. When the touch sensor 711 detects that the outer surface of the conveying box 503 is in contact with the inner wall of the lifting frame 710, the touch sensor 711 detects the touch by sending and receiving ultrasonic signals. When the object touches the lifting frame 710, the touch sensor 711 is used to detect the touch. 0, the propagation path of the sound wave will be changed, thereby affecting the reception of the signal. The second air pump 715 is started again through the external control system, and the second valve 716 on the surface of the air outlet pipe is opened to extract gas into the inside of the air delivery pipe 717, thereby extracting gas into the inside of the four hollow rods 712, so that the second piston 714 moves downward under the action of air pressure, thereby driving the lifting pipe 713 to move downward, so that the telescopic sleeve 709 is shortened, which facilitates the rotation of the conveying box 503. Through the action of the dustproof component 7, the limestone, the raw material for cement production, is effectively prevented from releasing dust into the environment to pollute the air during the transportation process.

[0044] The use method and working principle of the device: In the cement production process, when it is necessary to transport the raw material limestone for cement production, the chain conveyor device 2 is first started. The operation of the chain conveyor device 2 drives a plurality of relatively arranged connecting blocks 501 to move along the rotation of the two chains, thereby driving a plurality of conveying boxes 503 to move. Figure 2 and Figure 5As shown, the movement of the delivery box 503 drives the L-shaped slide plate 505 to move. When the slide plate 505 moves to the bottom of the storage bin 401, since the top of the slide plate 505 is higher than the bottom of the storage bin 401 and lower than the bottom of the baffle 406, when the delivery box 503 continues to move toward the storage bin 401, the slide plate 505 is pushed by the storage bin 401 and moves toward the mounting frame 506, thereby causing the two first springs 508 to be squeezed and shortened, so that the delivery box 503 is opened. At the same time, when the slide plate 505 moves to the bottom of the storage bin 401, the first air pump 513 is started, and the first valve 514 on the surface of the air inlet pipe is opened to deliver gas to the inside of the hollow tube 510, thereby driving the first piston 51 1 moves in the direction of the push rod 512 until the push rod 512 is extended to its longest position. When the outer surface of the slide plate 505 contacts the outer surface of the storage bin 401, the outer surface of the push rod 512 just contacts the outer surface of the baffle 406 and pushes the baffle 406 outward along the movement of the conveying box 503, so that the two second springs 405 connected thereto are squeezed and shortened, thereby creating a gap between the baffle 406 and the inside of the storage bin 401, so that the limestone in the conveying box 503 falls downward into the inside of the conveying box 503 under the action of its own gravity. When the outer surface of the hollow tube 510 moves to contact the outer surface of the storage bin 401, it just contacts the pressure sensor 407. When the pressure sensor 407 detects the external pressure, The signal is transmitted to the external control system, which starts the first air pump 513 again through the external control system, and opens the first valve 514 on the surface of the suction pipe to draw gas into the interior of the hollow tube 510, so that the interior of the hollow tube 510 is in a negative pressure state, and then the first piston 511 moves toward the direction of the first air pump 513 under the action of the negative pressure, thereby driving the push rod 512 to move in the direction of the first air pump 513, thereby separating the push rod 512 from the baffle 406, and the two second springs 405 can extend under the action of their own elastic force, thereby driving the baffle 406 to reset and seal the bottom of the storage bin 401. At this time, the two cylinders 502 matching the conveying box 503 are started through the external control system to shrink it. The conveying box 503 is short, which drives the conveying box 503 to move downward, thereby driving the slide plate 505 to move downward and separate it from the outer surface of the storage bin 401, so that the two first springs 508 are no longer squeezed and extend under the action of their own elastic force, thereby driving the slide plate 505 to move away from the mounting bracket 506 until it contacts the inner wall of the conveying box 503, that is, the sealing of the conveying box 503 is completed. While the conveying box 503 is sealed, it continues to move forward with the chain conveyor 2 to transport the limestone. Since the limestone is relatively stationary with the conveying box 503 during the transportation process, it will not cause excessive friction to the interior of the conveying box 503. When the conveying box 503 filled with limestone moves to one end of the chain conveyor 2,First, the distance between the slide plate 505 and the protrusion 610 is detected by the photoelectric sensor 611. When the slide plate 505 moves close to the longest protrusion in the protrusion 610, the drive motor 606 is started by the external control system to drive the protrusion 610 to rotate clockwise, thereby driving the multiple protrusions of different lengths on the protrusion 610 to rotate. During the rotation of the protrusion 610, the coil spring 609 is stretched and elongated. The rotation of the protrusion 610 causes it to exert an upward thrust on the slide plate 505. Figure 2 and Figure 3 As shown, when the slide plate 505 moves to a position close to the protrusion 610, it will move along an arc driven by the chain conveyor 2, as shown in FIG. Fig. 9As shown, the raised portion on the surface of the protrusion 610 becomes shorter in clockwise order along the longest protrusion, and the shortened length matches the distance from the center position of the protrusion 610 when the slide plate 505 rotates downward along the arc. As the protrusion 610 rotates, the slide plate 505 is continuously pushed upward, so that the two first springs 508 are squeezed and shortened. As the slide plate 505 rotates downward and opens, the limestone placed in the conveying box 503 falls downward to the inside of the collecting bin 701 under the action of its own gravity, and the conveying of the limestone is completed. When the photoelectric sensor 611 detects that the shortest raised portion on the surface of the protrusion 610 rotates to contact the outer surface of the slide plate 505, a signal is transmitted to the external control system, and the control system is activated The two electric push rods 604 shorten the protrusion 610 and move it to a position away from the slide plate 505 to turn off the drive motor 606. The drive motor 606 does not have a self-locking function. When the drive motor 606 is turned off, the coil spring 609 shortens under its own elastic force, thereby driving the protrusion 610 to rotate in the opposite direction and reset. When the automatic feeding component 5 moves to the bottom of the chain conveyor 2, the first air pump 513 on the automatic feeding component 5 is started again to deliver gas to the inside of the hollow tube 510, driving the push rod 512 to extend to its longest length. At the same time, the two cylinders 502 on the automatic feeding component 5 are started to extend it, driving the conveying box 503 to move in a direction away from the chain conveyor 2. When the limestone for cement production is transported When the conveying box 503 reaches the inside of the collecting bin 701, in order to prevent the dust in the limestone from polluting the air during the falling process, when the conveying box 503 moves to the top of the collecting bin 701, the second air pump 715 is first started, and the second valve 716 on the surface of the air inlet pipe is opened to convey gas to the inside of the air delivery pipe 717, so that the inside of the four hollow rods 712 is filled with gas, and then the four second pistons 714 move upward under the action of air pressure, and then drive the four lifting pipes 713 to move upward, thereby driving the lifting frame 710 to move upward, and then the telescopic sleeve 709 is extended, and then, the two fans 704 are started respectively to absorb gas to the outside respectively, so that the inside of the collecting bin 701 is in a negative pressure state, so that the downward moving The moving dust moves to the inside of the two conveying pipes 706 under the action of negative pressure. In order to prevent large particles of limestone from entering the inside of the two conveying pipes 706 during the process of falling downward, the two leak hole blocks 705 are used to effectively protect the two fans 704. After the dust enters the two temporary storage boxes 707 along the two conveying pipes 706, the two exhaust valves 708 are opened, so that the gas entering the temporary storage box 707 is discharged outward along the exhaust valves 708. When the touch sensor 711 detects that the outer surface of the conveying box 503 is in contact with the inner wall of the lifting frame 710, the second air pump 715 is started again through the external control system, and the second valve 716 on the surface of the outlet pipe is opened to extract gas into the inside of the air pipe 717.Thus, gas is drawn into the interior of the four hollow rods 712, so that the second piston 714 moves downward under the action of gas pressure, and then drives the lifting tube 713 to move downward, so that the telescopic sleeve 709 is shortened, which facilitates the rotation of the conveying box 503. Among them, the external control system is connected with the chain conveying device 2, the pressure sensor 407, the cylinder 502, the first air pump 513, the electric push rod 604, the drive motor 606, the photoelectric sensor 611, the fan 704, the touch sensor 711 and the second air pump 715.
