Description

Technical Field

[0001] The invention relates to the technical field of coal block conveying equipment, and in particular to an automatic feeding device for preventing coal block raw materials from being squeezed and broken. Background Art

[0002] In the process of conveying and feeding coal raw materials, related screw conveying equipment is usually used. When in use, the coal raw materials fed through the feed hopper are conveyed from one end to the other along the internal channel of the machine body through the rotation of the spiral blades installed inside the machine body.

[0003] However, the feeding structure of the existing screw conveying equipment is generally simple and single. The coal block raw materials are generally fed directly, so that the coal block raw materials are fed continuously, and the amount of feeding cannot be controlled. When the amount of coal block raw materials fed at one time is too much or is fed continuously, due to the limited processing capacity of the screw conveying equipment, a large number of coal blocks cannot be transported to the interior of the equipment in time, resulting in the accumulation of coal blocks in the feed hopper of the machine body, resulting in the blockage of coal block raw materials. These blocked coal block raw materials will be strongly squeezed and rubbed under the rotation of the rotating blades of the screw conveying equipment and the action of gravity, resulting in an increase in the coal block breakage rate, which will not only cause the screw conveying equipment to fail to work normally and affect the subsequent processing of the coal block raw materials, but also long-term blockage and overload operation will aggravate the wear of the screw conveying equipment, shorten the service life of the equipment, and increase maintenance costs.

[0012] Preferably, the arc surface away from the arc-shaped beating plate is fixedly connected with an I-shaped rod, and the I-shaped rod is slidably connected to the fixed frame, and the facing ends of the I-shaped rods on the same side are fixedly connected with sliding columns, and the sliding columns are slidably connected to the straight slots.

[0014] Preferably, the water storage ring is annularly and equidistantly fixed with a T-shaped water pipe, the end of the T-shaped water pipe away from the water storage ring passes through the feed hopper, and the end of the T-shaped water pipe passing through the feed hopper is fixedly connected with an atomizing nozzle, the piston rod is sealingly and slidably connected to the T-shaped water pipe, a second spring is fixedly connected between the T-shaped water pipe and the vertical rod, and the second spring is sleeved on the outside of the piston rod.

[0015] Preferably, the water mist spraying mechanism further comprises a sector gear fixedly connected to the opposite side of the linkage shaft, a tooth plate is fixedly connected to the vertical rod close to the sector gear, and the tooth plate is meshingly connected to the sector gear.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) When the coal raw materials are fed into the machine body through the feed hopper, the rotation of the rotating shaft is controlled by the driving motor, so that the disc and the lever installed on it can rotate synchronously. The lever can be used to move the plum blossom wheel, so that the material plate can be driven to rotate intermittently inside the feed hopper. Due to the special shape design of the plum blossom wheel and the equal rotation angle of the plum blossom wheel each time the lever is moved, the moving speed of the lever when following the rotation of the rotating shaft is consistent, so that the time for the plum blossom wheel to be moved each time is also equal, so that the material receiving time of each adjacent material plate is consistent, and the amount of coal raw materials received is also the same. During the subsequent rotation and pouring, the coal raw materials are intermittently transported into the machine body, effectively preventing the coal from accumulating and clogging in the feed hopper. , which ensures the continuity and stability of the conveying process. At the same time, during the intermittent rotation of the material plate, a fixed amount of coal blocks are fed into the machine body each time, avoiding the blockage caused by a large number of coal blocks pouring in at the same time, and providing time for the coal blocks in the feed hopper to rearrange and disperse, further reducing the risk of blockage. Since the material plates are arranged at equal distances, the amount of coal block raw materials entering the machine body each time can be kept consistent, thereby preventing excessive feeding of coal block raw materials from causing blockage at the connection between the feed hopper and the machine body, effectively reducing the accumulation of coal block raw materials, and avoiding the squeezing of coal block raw materials, which causes the coal block raw materials to break, resulting in a large amount of coal block residues left in the machine body, affecting the transportation of coal block raw materials and the normal use of the machine body.

[0017] (2) When the lever rotates to drive the plum blossom wheel to rotate intermittently and the material plate is used to intermittently and quantitatively discharge the coal raw materials, the transmission connection of the transmission member can synchronously drive the linkage shaft to rotate in coordination with the cam installed thereon when the rotating shaft rotates, and intermittently squeeze the pressure ball arranged on the side of the cam. In combination with the design of the first spring, the arc-shaped flapping plate can move back and forth on the side of the feed hopper, forming a flapping effect on the outer wall of the feed hopper, causing the outer wall of the feed hopper to vibrate during the flapping process. The vibration can effectively shake off the coal dust and impurities attached to the inner wall of the feed hopper, keep the feed hopper clean, reduce the interference of impurities on the coal transportation, promote the smooth feeding of the coal, avoid blockage or uneven feeding caused by coal dust and impurities, and thus improve the coal transportation efficiency.

[0018] Among them, the cam is composed of a circular ring structure and a protruding part, the pressed ball is a spherical object, and the outer surfaces of the cam and the pressed ball are both slippery surfaces. When the protruding part on the cam contacts the pressed ball, since the diameter of the protruding part of the cam is larger than the diameter of the circular ring structure, the rotation of the cam can form an extrusion effect on the pressed ball, pushing the pressed ball in the direction away from the cam. In conjunction with the design of the first spring, during the continued rotation of the cam, the arc-shaped flapping plate can flap the outer wall of the feed hopper, and the side edge of the cam is arranged to cooperate with the pressed ball. The intermittent extrusion of the pressed ball by the rotation of the cam can make the arc-shaped flapping plate move back and forth regularly, producing an effective and stable flapping effect, so that the force and time of the arc-shaped flapping plate flapping the outer wall of the feed hopper each time are consistent, and the design of the first spring can play a resetting role in this process. When the cam no longer squeezes the pressed ball, the first spring can push the arc-shaped flapping plate to reset and prepare for the next flapping action.

[0019] (3) In the process of beating the outer wall of the feed hopper, the rotation of the linkage shaft can not only drive the cam to rotate, but also drive the fan gear to rotate synchronously, and drive the tooth plate to move vertically. By using the second spring arranged between the vertical rod and the T-shaped water pipe, under the cooperation of the elastic force, the fan gear can synchronously drive the piston rod to move up and down inside the T-shaped water pipe while continuously rotating, so as to suck the water source in the water storage ring and spray it out from the atomizing nozzle in the form of atomized water mist. Since the atomizing nozzle is arranged in the feed hopper, the water mist sprayed by the atomizing nozzle will directly act on the surface of the coal block raw materials being discharged, spraying water mist on the coal block raw materials during the feeding process, so as to avoid the coal block raw materials being too dry in a dry environment, resulting in extrusion and damage during the feeding.

[0020] Among them, since the T-shaped water pipe is arranged in an annular shape and equidistantly on the water storage ring, multiple atomizing nozzles are evenly distributed at different positions in the feed hopper. When in use, the coal block raw materials can be sprayed from different positions, thereby increasing the uniformity of the coal blocks receiving water mist, and further improving the effect of spraying water mist on the coal block raw materials, so as to increase the wettability of the coal block raw materials and avoid the coal block raw materials from being too dry.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiments of the present invention: Please refer to Figures 1 to 9 As shown, an automatic feeding device for preventing coal block raw materials from being squeezed and broken includes a machine body 1, a feed hopper 2 is fixedly connected to the outer surface of the upper end of the front side of the machine body 1, a discharge hopper 3 is fixedly connected to the outer surface of the lower end of the rear side of the machine body 1, and the feed hopper 2 and the discharge hopper 3 are arranged far apart, and a fixing frame 4 is fixedly connected to one end of the machine body 1 facing the feed hopper 2, and the fixing frame 4 is arranged on the outer side of the feed hopper 2, and also includes: an intermittent feeding mechanism 5, a follow-up flapping mechanism 6 and a water mist spraying mechanism 7, and the intermittent feeding mechanism 5, the follow-up flapping mechanism 6 and the water mist spraying mechanism 7 are all arranged between the fixing frame 4 and the feed hopper 2.

[0025] The intermittent feeding mechanism 5 is used for intermittent feeding of coal block raw materials.

[0026] The follow-up beating mechanism 6 is used to beat the outer wall of the feed hopper 2 synchronously while the coal block raw materials are intermittently fed.

[0027] The water mist spraying mechanism 7 is used to spray water mist into the interior of the machine body 1 synchronously while the coal block raw materials are intermittently fed.

[0028] The intermittent feeding mechanism 5 includes a driving motor 501 fixedly connected to the fixing frame 4 . The output end of the driving motor 501 is fixedly connected to a rotating shaft 502 , and the rotating shaft 502 is rotatably connected between the inner walls of both sides of the fixing frame 4 .

[0029] A central axis 505 is rotatably connected between the inner walls on both sides of the fixed frame 4, and the central axis 505 is rotatably connected to the feed hopper 2. A material plate 507 is fixedly connected to the outer surface of the middle part of the central axis 505 in an annular shape and equidistantly, and the material plate 507 is arranged in the feed hopper 2. The outer surfaces of both ends of the central axis 505 are symmetrically fixedly connected with plum blossom wheels 506, and the outer surfaces of both ends of the rotating shaft 502 are symmetrically fixedly connected with turntables 503. The turntables 503 are fixedly connected with levers 504 on the opposite sides thereof, which are eccentric to the axis, and the levers 504 are used to drive the plum blossom wheels 506 to rotate.

[0030] The effects achieved by this embodiment are as follows: when the coal lump raw materials are fed into the interior of the machine body 1 through the feed hopper 2, the material receiving time of each two adjacent material plates 507 can be made consistent, and the amount of coal lump raw materials received is also the same. During the subsequent rotation and pouring, the coal lump raw materials are intermittently transported into the interior of the machine body 1, effectively preventing the coal lump from accumulating and clogging in the feed hopper 2, thereby ensuring the continuity and stability of the transportation process.

[0031] In addition, since the material plates 507 are arranged at equal distances, the amount of coal lump raw materials entering the body 1 each time can be kept consistent, thereby preventing excessive feeding of coal lump raw materials from causing blockage at the connection between the feed hopper 2 and the body 1, effectively reducing the accumulation of coal lump raw materials, and avoiding the squeezing of coal lump raw materials causing the coal lump raw materials to break, resulting in a large amount of coal lump residues left inside the body 1, affecting the transportation of coal lump raw materials and the normal use of the body 1.

[0032] Further examples: Please refer to Figures 1 to 9 As shown, the follow-up flapping mechanism 6 includes a linkage shaft 602 symmetrically connected to the inner walls on both sides of the fixed frame 4, and a transmission member 601 is transmission-connected between the linkage shaft 602 and the rotating shaft 502, and a cam 603 is fixedly connected to the outer surface of the linkage shaft 602.

[0033] The follow-up beating mechanism 6 also includes an arc-shaped beating plate 607 symmetrically fitted on the outside of the feed hopper 2, and a first spring 608 is fixedly connected between the arc-shaped beating plate 607 and the fixed frame 4, and an extension rod 606 is symmetrically fixedly connected to the arc surface on the side away from the arc-shaped beating plate 607, and a fixed block 604 is fixedly connected to the end away from the extension rod 606, and a compressed ball 605 is fixedly connected to the fixed block 604 on the side facing the cam 603, and the cam 603 is used to squeeze and push the compressed ball 605 to move.

[0034] U-shaped frames 613 are symmetrically fixedly connected to the inner walls on both sides of the fixing frame 4, and a linkage frame 611 is rotatably connected between the opposite vertical surfaces of the U-shaped frame 613. Straight notches 612 are symmetrically opened at both ends of the linkage frame 611.

[0035] The arc surface away from the arc-shaped beating plate 607 is fixedly connected with an I-shaped rod 609, and the I-shaped rod 609 is slidably connected with the fixing frame 4. The facing ends of the I-shaped rods 609 on the same side are fixedly connected with a sliding column 610, and the sliding column 610 is slidably connected with the straight slot 612.

[0036] The effects achieved by this embodiment are as follows: when the lever 504 rotates to drive the plum blossom wheel 506 to rotate intermittently and the material plate 507 is used to intermittently and quantitatively discharge the coal raw materials, the arc-shaped beating plate 607 can be used to beat the outer wall of the feed hopper 2, so that the outer wall of the feed hopper 2 vibrates during the beating process. The vibration can effectively shake off the coal dust and impurities attached to the inner wall of the feed hopper 2, keep the feed hopper 2 clean, reduce the interference of impurities on the transportation of coal blocks, promote the smooth discharge of coal blocks, avoid blockages or uneven feeding caused by coal dust and impurities, and thus improve the transportation efficiency of coal blocks.

[0037] Further examples: Please refer to Figures 1 to 9 As shown, the water mist spraying mechanism 7 includes a water storage ring 702 fixedly connected to the bottom of the fixed frame 4, the water storage ring 702 is fixedly connected with a water pipe 703, the outer ring surface of the feed hopper 2 is slidably connected with an annular top plate 710, the bottom of the annular top plate 710 is annularly equidistantly fixed with vertical rods 708, and the bottom of the vertical rods 708 is fixedly connected with a piston rod 706.

[0038] A T-shaped water pipe 704 is fixedly connected to the water storage ring 702 at equal intervals in an annular shape, and a one-way valve is arranged between the T-shaped water pipe 704 and the water storage ring 702. The end of the T-shaped water pipe 704 away from the water storage ring 702 passes through the feed hopper 2, and the end of the T-shaped water pipe 704 passing through the feed hopper 2 is fixedly connected to an atomizing nozzle 705. The piston rod 706 is sealingly and slidably connected to the T-shaped water pipe 704. A second spring 707 is fixedly connected between the T-shaped water pipe 704 and the vertical rod 708, and the second spring 707 is sleeved on the outside of the piston rod 706.

[0039] The water mist spraying mechanism 7 also includes a sector gear 701 fixedly connected to the opposite side of the linkage shaft 602 , a tooth plate 709 is fixedly connected to the vertical rod 708 close to the sector gear 701 , and the tooth plate 709 is meshingly connected to the sector gear 701 .

[0040] The effects achieved by this embodiment are as follows: in the process of beating the outer wall of the feed hopper 2, the piston rod 706 can be driven to move up and down reciprocatingly inside the T-shaped water pipe 704, and the water source in the water storage ring 702 is sucked, so that the water source is sprayed out from the atomizing nozzle 705 in the form of atomized water mist. Since the atomizing nozzle 705 is arranged in the feed hopper 2, the water mist atomized and sprayed by the atomizing nozzle 705 will directly act on the surface of the coal block raw materials being discharged, and spray water mist on the coal block raw materials in the feeding process to avoid the coal block raw materials being too dry in a dry environment, resulting in squeezing and breakage of the discharged materials.

[0041] The complete usage steps and working principle of the above embodiment are as follows: The following is the working process of the intermittent feeding mechanism 5 for intermittent feeding of coal block raw materials: When in use, the coal block raw material enters the interior of the machine body 1 through the feed hopper 2. Figure 2 As shown in the figure, a spiral blade is installed, and the coal block raw material can be transported by the rotation of the spiral blade, and finally discharged from the discharge hopper 3. When the coal block raw material enters the inside of the feed hopper 2, as shown in the figure, Figure 2 and Figure 5 As shown, since the inner walls on both sides of the fixing frame 4 are rotatably connected with the rotating shaft 502 and the central shaft 505 in sequence, and the rotating shaft 502 is fixedly connected to the output end of the driving motor 501, the central shaft 505 is rotatably connected with the feed hopper 2, and the outer surface of the middle part of the central shaft 505 is annularly and equidistantly fixed with material plates 507, so that the distance between two adjacent material plates 507 can be equal. When the coal block raw material is delivered to the inside of the feed hopper 2, it will preferentially fall into the gap formed between the two adjacent material plates 507. At the same time, the driving motor 501 synchronously drives the rotating shaft 502 to rotate, and the A turntable 503 is symmetrically fixedly connected to the outer surface of both ends of the rotating shaft 502, and a lever 504 is fixedly installed on the opposite side of the rotating shaft 503, and a plum blossom wheel 506 is symmetrically fixedly arranged on the outer surface of both ends of the central shaft 505, and the plum blossom wheel 506 and the lever 504 are adapted. When the driving motor 501 drives the rotating shaft 502 to rotate on the fixed frame 4, the rotating disk 503 will rotate synchronously with the rotation of the rotating shaft 502. At this time, the position of the lever 504 changes synchronously. The lever 504 can be driven to rotate intermittently, and the plum blossom wheel 506 rotates. At the same time, the material plate 507 is synchronously driven to rotate with the central axis 505 as the axis through the connection with the central axis 505. At this time, the coal block material falling between the two adjacent material plates 507 will be transported from the feed hopper 2 to the machine body 1 under the rotation of the material plates 507. In this process, through the intermittent material discharge mechanism 5, since the rotation angle of the plum blossom wheel 506 is equal each time the lever 504 moves, and the moving speed of the lever 504 is consistent, the time when the plum blossom wheel 506 is moved each time is also equal, so that the material receiving time of each two adjacent material plates 507 is consistent, and the received The amount of coal raw materials is also the same. During the subsequent rotation and pouring, the coal raw materials are intermittently transported into the machine body 1. Since the material plates 507 are equidistantly arranged, the amount of coal raw materials entering the machine body 1 each time can be kept consistent, thereby preventing excessive discharge of coal raw materials from causing blockage at the connection between the feed hopper 2 and the machine body 1, reducing the accumulation of coal raw materials, and avoiding squeezing of coal raw materials to cause breakage of coal raw materials, resulting in a large amount of coal residues left inside the machine body 1, affecting the transportation of coal raw materials and the normal use of the machine body 1.

[0042] Please refer to the above working process Figures 1 to 9 .

[0043] The following is the working process of the follow-up beating mechanism 6 beating the outer wall of the feed hopper 2 synchronously while the coal block raw material is intermittently discharged: When the driving motor 501 drives the rotating shaft 502 to rotate on the fixing frame 4, Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, since the lower end of the rotating shaft 502 is connected to the linkage shaft 602 through the transmission member 601, and the linkage shaft 602 is rotatably connected to the fixed frame 4, a cam 603 is fixedly arranged on the outer surface of the linkage shaft 602, and an arc-shaped beating plate 607 that is initially in contact with each other is symmetrically arranged on the outer side of the feed hopper 2, and the arc-shaped beating plate 607 is fixedly connected to the fixed block 604 through two symmetrical extension rods 606, and the fixed block 604 is installed with a pressure ball 605 on the side facing the cam 603. When the rotating shaft 502 rotates, the linkage shaft 602 can be driven to rotate synchronously with the fixed frame 4 through the transmission of the transmission member 601 (it should be noted here that the transmission member 601 is composed of two transmission wheels and a transmission belt connected between the two transmission wheels, and the two transmission wheels are respectively fixedly connected to the outer surfaces of the rotating shaft 502 and the linkage shaft 602. When the rotating shaft 502 rotates, the two transmission wheels can be driven by the transmission of the transmission belt The transmission wheels rotate synchronously, so that when the rotating shaft 502 rotates, the linkage shaft 602 can synchronously rotate on the fixed frame 4), and when the linkage shaft 602 rotates, the cam 603 installed on the linkage shaft 602 synchronously follows the rotation and approaches the direction of the compressed ball 605. When the cam 603 contacts the compressed ball 605, since the first spring 608 is fixedly connected between the arc-shaped flapping plate 607 and the fixed frame 4, initially, the arc-shaped flapping plate 607 can be driven to approach the outer wall of the feed hopper 2 under the elastic force of the first spring 608. By setting the connection mode of the first spring 608, the arc-shaped flapping plate 607 can be movable and can be changed in position. When the cam 603 contacts the compressed ball 605, the compressed ball 605 can be squeezed, driving the arc-shaped flapping plate 607 to move synchronously in the direction away from the feed hopper 2. At this time, the first spring 608 is synchronously squeezed. Figure 6 As shown, because the mutually adaptable structure formed between the cam 603 and the compressed ball 605 is symmetrically arranged at the two ends of the arc-shaped flapping plate 607, and the two linkage shafts 602 are both connected to the rotating shaft 502 in transmission, the two linkage shafts 602 can keep the movement synchronous when the rotating shaft 502 rotates, that is, the two cams 603 can also rotate at the same time and squeeze the adjacent compressed balls 605, so that the thrust on both sides of the arc-shaped flapping plate 607 is kept consistent, so that the movement process of the arc-shaped flapping plate 607 can be kept on the same axis, thereby improving the stability of the arc-shaped flapping plate 607 during movement.

[0044] It should be noted that, Figure 4As shown in the figure, the cam 603 is composed of a circular ring structure and a protruding portion, and the pressure ball 605 is a spherical object, and the outer surfaces of the cam 603 and the pressure ball 605 are both slippery surfaces. When the cam 603 rotates, the protruding portion on the cam 603 will gradually rotate close to the outer surface of the pressure ball 605. When the protruding portion on the cam 603 contacts the pressure ball 605, since the diameter of the protruding portion of the cam 603 is larger than the diameter of the circular ring structure, the rotation of the cam 603 can make the protruding portion slide over the surface of the pressure ball 605. When the protruding portion on the cam 603 and the outer surface of the pressure ball 605 are in sliding contact, due to the reduction of space, the cam 603 will form an extrusion effect on the pressure ball 605, so that the pressure ball 605 is pushed away from the cam 603. At this time, through the change of the position of the pressure ball 605, the arc-shaped flapping plate 60 7 position synchronously follows the change, the arc-shaped slapping plate 607 will move in the direction away from the feed hopper 2, so that the arc-shaped slapping plate 607 and the outer wall of the feed hopper 2 gradually lose contact, and the first spring 608 is compressed at this time. When the cam 603 continues to rotate, so that the upper protrusion thereof loses contact with the pressed ball 605, the squeezing effect of the upper protrusion of the cam 603 on the pressed ball 605 disappears. Under the elastic force of the first spring 608, the arc-shaped slapping plate 607 can be pushed in the direction of the feed hopper 2, so that the arc-shaped slapping plate 607 is re-attached to the outer wall of the feed hopper 2, and so on and so forth, so that the arc-shaped slapping plate 607 can form a slapping effect on the outer wall of the feed hopper 2, so that the outer wall of the feed hopper 2 vibrates during the slapping process, and the vibration can effectively reduce the occurrence of coal dust impurities generated during the feeding process of coal block raw materials adhering to the inner wall of the feed hopper 2.

[0045] Furthermore, by setting the movement process of the arc-shaped beating plate 607 to follow the rotation synchronous transmission of the rotating shaft 502, the outer wall of the feed hopper 2 can be simultaneously beat while the coal block raw material is intermittently and quantitatively discharged, so that the vibration generated by the beating can be used to remove the coal dust impurities remaining on the inner wall of the feed hopper 2 when the coal block raw material is discharged, thereby saving energy consumption and eliminating the need for subsequent manual cleaning by workers, making the operation process more complete, the structure more compact, and effectively improving the degree of automation of the equipment.

[0046] like Figure 2 , Figure 3 as well as Figure 6 As shown, since the arc-shaped beating plates 607 are symmetrically arranged on the outer side of the feed hopper 2, and the arc-shaped beating plates 607 are fixedly installed with I-shaped rods 609, and the I-shaped rods 609 penetrate and slide through the fixed frame 4, when the arc-shaped beating plates 607 move through the cooperation of the cam 603 and the pressure ball 605, the I-shaped rods 609 can provide a limiting basis for the movement of the arc-shaped beating plates 607, so that the I-shaped rods 609 can penetrate and slide synchronously on the fixed frame 4, so that the arc-shaped beating plates 607 can move on the same axis. Figure 3and Figure 6 As shown, the facing ends of the two I-shaped rods 609 are fixedly connected to the sliding column 610, and U-shaped frames 613 are symmetrically fixed on the inner walls on both sides of the fixed frame 4. The U-shaped frame 613 is rotatably connected with a linkage frame 611, and straight grooves 612 are symmetrically provided on both sides of the linkage frame 611. The sliding column 610 is slidably connected in the straight groove 612. When the arc-shaped flapping plate 607 moves in the direction away from the feed hopper 2 and synchronously drives the I-shaped rod 609 to move (it should be noted here that since only one of the two arc-shaped flapping plates 607 is provided to move through the cooperation of the cam 603 and the pressure ball 605, in the initial stage of the cooperation of the cam 603 and the pressure ball 605, only one of the arc-shaped flapping plates 607 is driven to move, and the I-shaped rod 609 connected to the arc-shaped flapping plate 607 will synchronously follow and move in the direction away from the other I-shaped rod 609), it can drive the sliding column set at the end of the I-shaped rod 609 610 slides in the straight slot 612, and the sliding of the sliding column 610 can drive the linkage frame 611 to rotate on the U-shaped frame 613. At this time, the other end of the linkage frame 611 passes through the straight slot 612 and penetrates the sliding column 610 that is slidably connected. Under the rotation of the linkage frame 611, it can be synchronously pushed to slide in the straight slot 612, and push another I-shaped rod 609, so that the two I-shaped rods 609 form a state of moving away from each other. Since the I-shaped rod 609 is installed on the arc-shaped flapping plate 607, when the two I-shaped rods 609 move away from each other, the two arc-shaped flapping plates 607 also move synchronously in the direction away from the feed hopper 2, so that the two arc-shaped flapping plates 607 maintain a synchronous state to move and synchronously flap the outer wall of the feed hopper 2. This design can effectively reduce the number of settings of the transmission member 601, the cam 603 and the pressure ball 605 related structures, and realize the movement synchronization between the two arc-shaped flapping plates 607.

[0048] The following is the working process of the water mist spraying mechanism 7 spraying water mist into the interior of the machine body 1 while the coal raw materials are intermittently fed: When the linkage shaft 602 rotates and drives the cam 603 to rotate synchronously, Figure 2 , Figure 5 , Figure 6 as well as Fig. 9As shown, since the opposite ends of the linkage shaft 602 are fixedly connected with the sector gear 701, and the side of the sector gear 701 is meshed with a tooth plate 709, and the tooth plate 709 is fixedly installed on the vertical rod 708, as the linkage shaft 602 rotates, the sector gear 701 will also synchronously follow the linkage shaft 602 to rotate as the axis. Initially, the sector gear 701 is not meshed with the tooth plate 709. When the sector gear 701 rotates, its upper teeth gradually approach the tooth plate 709 and finally mesh with the tooth plate 709. Through the meshing between the teeth, the tooth plate 709 can be driven to move upward synchronously with the vertical rod 708, as shown in FIG. Figure 7 , Figure 8 as well as Fig. 9As shown, an annular top plate 710 is fixedly arranged on the top of the vertical rod 708, and the annular top plate 710 is slidably arranged on the outer wall of the feed hopper 2. When the vertical rod 708 moves upward, the annular top plate 710 can be synchronously driven to slide upward on the outer wall of the feed hopper 2, thereby driving multiple vertical rods 708 to move upward synchronously. In addition, because the bottom of the vertical rod 708 is fixedly connected to the piston rod 706, the piston rod 706 is sealingly slidably connected in the T-shaped water pipe 704, and the second spring 707 is fixedly connected between the vertical rod 708 and the T-shaped water pipe 704, when the vertical rod 708 moves upward, the piston rod 706 can be driven to slide upward synchronously inside the T-shaped water pipe 704. At the same time, the second spring 707 is driven by the vertical rod 708 to The upward force will also be stretched. Since the lower end of the fixed frame 4 is fixedly connected to the water storage ring 702, and the water storage ring 702 can be connected to an external container with a water source through a water pipe 703, and a T-shaped water pipe 704 is fixedly connected to the water storage ring 702, and a one-way valve is arranged between the T-shaped water pipe 704 and the water storage ring 702. When the vertical rod 708 moves to drive the piston rod 706 to slide upward synchronously with the inside of the T-shaped water pipe 704, the water source can be pumped from the inside of the water storage ring 702 through the one-way valve into the inside of the T-shaped water pipe 704. Since the feeding movement of the coal block raw material continues, the linkage shaft 602 will also continue to rotate, so that the fan gear 701 continues to rotate. When the fan gear When the wheel 701 continues to rotate, it will gradually lose contact with the tooth plate 709 and release the meshing relationship between them. As the meshing effect on the tooth plate 709 disappears, the vertical rod 708 will be pulled downward by the elastic force of the second spring 707, so that the vertical rod 708 returns to its initial position. At this time, the downward movement of the vertical rod 708 will also drive the piston rod 706 to slide downward in the T-shaped water pipe 704, and the sucked water source will be sprayed out in the form of atomized water mist through the atomizing nozzle 705 installed at one end of the T-shaped water pipe 704 away from the water storage ring 702. Since the T-shaped water pipe 704 is fixedly connected to the lower end of the feed hopper 2, and the atomizing nozzle 705 is synchronously arranged in the feed hopper 2, the water source will be sprayed out in the form of atomized water mist. The water mist sprayed by the atomizing nozzle 705 will directly act on the surface of the coal block raw materials, and spray water mist on the coal block raw materials in the feeding process to avoid the coal block raw materials from being too dry in a dry environment, which will cause squeezing and breakage of the materials. In this process, since the T-shaped water pipe 704 is equidistantly arranged on the water storage ring 702, multiple atomizing nozzles 705 are evenly distributed at different positions in the feed hopper 2. When in use, the coal block raw materials can be sprayed from different positions, thereby increasing the uniformity of the coal blocks receiving water mist, and further improving the effect of spraying water mist on the coal block raw materials, so as to increase the wettability of the coal block raw materials and avoid the coal block raw materials from being too dry.
