[0031] The present invention is described in more detail below with reference to the embodiments.

[0032] Embodiment 1

[0033] See also Figure 1 to Figure 2 The sealed material guide chute of this embodiment includes a material guide chute body 1, and a plurality of material guide frames 2 for supporting are arranged on both sides of the material guide chute body 1. A conveyor belt 7 for conveying coal is arranged at the bottom of the material guide chute body 1. A hopper 10 is arranged at the end of the material guide chute body 1 protruding outward. The top of the hopper 10 is opened, and a movable cover 5 that can be opened and closed is hinged at the top opening of the hopper 10.

[0034] Specifically, both sides of the material guide chute body 1 are material blocking side plates 8, and the bottom end of the material guide chute body 1 is a coal blocking plate 9. At the same time, the side of the movable cover 5 away from the material guide chute body 1 is hinged to the hopper 10 through a hinge joint 6, and a sealing strip is installed at the cover of the movable cover 5. The setting of the sealing strip material side plates 8 and the coal blocking plate 9 guides the coal in the material guide chute body 1, which can ensure the sealing of the inside of the material guide chute body 1 and prevent the coal from leaking from the joints.

[0035] In this embodiment, a hopper 10 and a movable cover 5 are arranged at the end of the material guide chute body 1, and are equipped with sealing strips. While significantly improving the sealing performance of the material guide chute body 1 and reducing the occurrence of material leakage, the design of the movable cover 5 and the hopper 10 is convenient for cleaning personnel to quickly open and deal with the leaked materials, avoiding the tedious operation of manual cleaning one bucket at a time under the traditional plugging plate structure, greatly reducing the labor intensity of cleaning personnel, saving time and labor costs, and also reducing material waste and environmental pollution, thereby improving the overall efficiency and environmental performance of the material conveying system of the thermal power plant.

[0036] Embodiment 2

[0037] See also Figures 3 to 7 On the basis of the above-mentioned embodiment 1, an installation box 1001 is fixedly installed on the side of the hopper 10 away from the material guide trough body 1. The installation box 1001 is divided into two installation grids by a partition. A vibrating mechanism 4 is installed in each installation grid. The vibrating mechanism 4 includes a vibrating hammer 1801 and a swinging mechanism for driving the vibrating hammer 1801 to swing. The vibrating hammer 1801 is slidably fitted to the outer wall of the hopper 10. The vibrating hammer 1801 is used to vibrate the outer wall of the hopper 10 to shake off the material with high viscosity adhering to the hopper 10.

[0038] Specifically, the rocking mechanism includes an inverted T-shaped plate 13, on which a driving rod 15 is rotatably installed on the side of the T-shaped plate 13 away from the hopper 10, and a knocking rod 18 and a toggle rod 16 are sequentially sleeved on the driving rod 15 from one side of the T-shaped plate 13 to the outside, the knocking rod 18 is rotatably sleeved with the driving rod 15, and a vibrating hammer 1801 is fixedly installed on the top of the knocking rod 18 on the side close to the hopper 10.

[0039] Among them, the toggle rod 16 includes a socket block 1601 fixedly socketed with the driving rod 15 and two toggle rods 1602 fixed on the side of the socket block 1601 and staggered at a certain angle. The free end of each toggle rod 1602 is fixedly connected to a toggle shaft 17 on one side close to the T-shaped plate 13 for toggle the knocking rod 18 to swing.

[0040] Meanwhile, the swing mechanism further includes a driving motor for driving the driving rod 15 to rotate.

[0041] Starting the driving motor can drive the driving rod 15 to rotate, and the rotation of the driving rod 15 can drive the toggle rod 16 to swing. Due to the setting of the toggle shaft 17, the toggle rod 16 can drive the toggle shaft 17 to move while swinging, and then the toggle shaft 17 drives the knocking rod 18 to swing, so that the knocking rod 18 drives the vibrating hammer 1801 to vibrate at different positions, which can effectively improve the vibration effect.

[0042] In addition, in this embodiment, through the installation box 1001 and the installation grid, multiple sets of vibrating mechanisms 4 can be installed to further vibrate various positions of the hopper 10 to improve the coal feeding effect.

[0043] Furthermore, the knocking rod 18 is fixedly connected to a sleeve tube 19 on one side close to the hopper 10, and a rotating shaft is rotatably sleeved in the sleeve tube 19. After the free end of the rotating shaft extends out of the sleeve tube 19, it is vertically fixedly connected to an extrusion cylinder 20 with a sealed upper end. A power storage rod 21 is sleeved inside the extrusion cylinder 20. After the top end of the power storage rod 21 slides through the extrusion cylinder 20, it is fixedly connected to a top cover 22. After the bottom end of the power storage rod 21 extends out of the extrusion cylinder 20, it is fixedly connected to a clamping plate 24. The bottom end of the clamping plate 24 is provided with two arc-shaped grooves arranged at intervals. The T-shaped plate 13 is fixedly connected to two support rods 27 arranged laterally in parallel on one side close to the hopper 10. The two support rods 27 are respectively clamped with the two arc-shaped grooves in a one-to-one correspondence.

[0044] Among them, a limit block 23 is fixedly sleeved on the force storage rod 21 , a spring 25 is fixedly arranged between the top end of the limit block 23 and the top end inside the extrusion cylinder 20 , and the spring 25 is sleeved on the force storage rod 21 .

[0045] The setting of the limit block 23 and the extrusion cylinder 20 can make the spring 25 in a compressed state to accumulate elastic force when the knocking rod 18 swings to the vertical position. When the driving shaft 17 drives the knocking rod 18 to swing toward both sides, the elastic force accumulated in the spring 25 will be released. At this time, the knocking rod 18 will move quickly to both sides to drive the vibrating hammer 1801 to hammer the installation box 1001, thereby causing strong vibration of the hopper 10. Combined with the vibration function of the vibrating hammer 1801 itself, double vibration can be achieved, which can further improve the unloading effect of the ash hopper.

[0046] In this embodiment, the T-shaped plate 13 is fixedly connected to the outer side wall of the hopper 10 via two connecting columns 14 .

[0047] Embodiment 3

[0048] See also Figure 3 , Figure 4 as well as Figure 8 On the basis of the above-mentioned embodiment 1 or embodiment 2, a fixed bracket 3 is fixedly provided at the top of the guide trough body 1, and a crushing mechanism 11 is fixedly installed on the outer side of the fixed bracket 3. The crushing mechanism 11 includes a rectangular frame 28, a lifting mechanism and a crushing frame. The crushing frame includes a left fixed plate 32 and a right fixed plate 33 which are staggered up and down. Four upper squeezing rollers 38 which are arranged at intervals are fixedly connected to the side of the left fixed plate 32 close to the right fixed plate 33, and five lower squeezing rollers 39 are fixedly connected to the side of the right fixed plate 33 close to the left fixed plate 32. The projections of each upper squeezing roller 38 and each lower squeezing roller 39 in the vertical direction are staggered in sequence. When the hopper 10 is added with spilled coal, the large lumps of coal can be crushed by squeezing the upper squeezing rollers 38 and the lower squeezing rollers 39.

[0049] The lifting mechanism includes two lifting rods, namely a left lifting rod 31 and a right lifting rod 34 .

[0050] The left lifting rod 31 is fixedly connected to the left fixing plate 32 , and the right lifting rod 34 is fixedly connected to the right fixing plate 33 .

[0051] At the same time, the lifting mechanism also includes a driving mechanism for driving the left fixing plate 32 and the right fixing plate 33 to move closer to or away from each other.

[0052] By driving the left fixed plate 32 and the right fixed plate 33 closer to each other through the driving mechanism, the upper squeezing roller 38 can pass through the gap between the lower squeezing rollers 39, so that the large lumps of coal are squeezed and broken to prevent clogging of the hopper. At the same time, the problem of coal jamming in the guide chute body 1 can also be effectively avoided, ensuring the smooth operation of the conveying system.

[0053] Specifically, the driving mechanism includes a telescopic member 29 fixed at the top of the rectangular frame 28, a synchronization rod 35 fixed at the bottom of the telescopic member 29, two limit sliding sleeves 30 provided on both sides of the rectangular frame 28, and a swing mechanism.

[0054] In this embodiment, the free end of the synchronization rod 35 is fixedly connected to the limiting sleeve 30 fixed to the left lifting rod 31 , and the top ends of the two lifting rods are fixedly connected to the two limiting sleeves 30 respectively.

[0055] The swing mechanism includes two swing units respectively arranged on the front and rear sides of the bottom end of the rectangular frame 28, and the swing unit includes a swing rod 37 and two limit sleeves 36. The two limit sleeves 36 are respectively hinged to two lifting rods. The middle part of the swing rod 37 is hinged to the rectangular frame 28 through a hinge shaft 40, and the two ends of the swing rod 37 are slidably sleeved with the limit sleeves 36.

[0056] Specifically, by starting the telescopic member 29, the telescopic end of the telescopic member 29 moves, and the telescopic member 29 can drive the synchronization rod 35 to move up and down, and then the synchronization rod 35 can drive the limiting sliding sleeve 30 to slide along the vertical rod of the rectangular frame 28, and the limiting sliding sleeve 30 can synchronously drive the left lifting rod 31 to move up and down.

[0057] At the same time, when the left lifting rod 31 moves, the swing rod 37 will swing under the limiting action of the hinge shaft 40, and the movement directions of the two ends of the swing rod 37 are opposite. Therefore, the swing of the swing rod 37 can drive the right lifting rod 34 to move in the opposite direction of the left lifting rod 31, and the right fixed plate 33 moves synchronously, thereby realizing the synchronous reverse movement of the left fixed plate 32 and the right fixed plate 33, and then crushing the large pieces of coal.

[0058] In this embodiment, a hydraulic lifting device is provided between the fixed bracket 3 and the material guide trough body 1 .

[0059] After the spilled coal is collected and loaded, the fixed support 3 can be lifted by the hydraulic lifting device, so that the crushing mechanism 11 is withdrawn from the hopper 10, and the movable cover 10 is closed to prevent the coal from spilling.

[0060] Embodiment 4

[0061] On the basis of the above-mentioned embodiment 1, embodiment 2 or embodiment 3, an operation box 12 for controlling power supply is installed on the material guide frame 2, and each motor is electrically connected to the operation box 12.

[0062] The working principle of the present invention is as follows: when there is spilled coal at the tail of the belt conveyor that needs to be cleaned up, the cleaning personnel opens the movable cover 5, collects the spilled residual material on the ground at the tail of the belt conveyor, and then uses a shovel to directly shovel the collected residual material into the hopper 10. The design of the movable cover 5 and the hopper 10 is convenient for the cleaning personnel to quickly open and handle the spilled material, avoiding the tedious operation of manually cleaning one bucket at a time under the traditional plugging plate structure, greatly reducing the labor intensity of the cleaning personnel, saving time and labor costs, and in addition, reducing material waste and environmental pollution, and improving the overall efficiency and environmental performance of the material conveying system of the thermal power plant.

[0063] When the viscosity of the spilled coal is high, the vibrating mechanism 4 can be started to vibrate the hopper 10 to avoid sticking. At the same time, the vibrating mechanism 4 can drive the vibrating hammer 1801 to hammer the installation box 1001 through the settings of the knocking rod 18, the power storage rod 21 and the spring 25, thereby causing strong vibration of the hopper 10. Combined with the vibration function of the vibrating hammer 1801 itself, double vibration can be achieved, which can further improve the unloading effect of the ash hopper.

[0064] When the volume of the spilled coal is large, the crushing mechanism 11 can be started, and the left fixed plate 32 and the right fixed plate 33 can be driven to approach each other through the driving mechanism, so that the upper squeezing roller 38 passes through the gap between the lower squeezing rollers 39, and the large lumps of coal are squeezed and crushed to prevent clogging of the hopper. At the same time, it can also effectively avoid the problem of coal jamming in the guide chute body 1, ensuring the smooth operation of the conveying system.

[0065] After all the residual materials are cleaned up, the hydraulic lifting device is started to lift the fixed bracket 3, so that the crushing mechanism 11 withdraws from the hopper 10, and the movable cover 10 is closed and the sealing condition is checked.
