[0002] Bucket wheel stacker-reclaimer is a large-scale continuous loading and unloading equipment, mainly used for the storage and reclaiming of bulk materials (such as coal, ore, sand and gravel, etc.). It can realize the functions of efficient material stacking and retrieving materials from the material pile, and is a key equipment in the automated process of bulk material handling.

[0003] During the use of the bucket wheel stacker and reclaimer, due to the large material drop difference between the bucket wheel and the conveyor belt, the material after picking up will have a strong impact on the conveyor belt when it falls onto the conveyor belt, which can easily damage the conveyor belt and generate a large amount of dust.

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.

[0034] Example 1

[0035] See also Figure 1-Figure 12 The dust prevention device for a bucket wheel stacker and reclaimer shown in the figure comprises a machine body 101, a cantilever 102 is mounted on the machine body 101, a conveyor belt 103 for conveying after reclaiming is arranged on the cantilever 102, a bucket wheel body 104 is arranged on one side of the cantilever 102, and a plurality of groups of hoppers 105 are fixed on the outer side of the bucket wheel body 104 in a circular array state, and each group of hoppers 105 is arranged in communication with the interior of the bucket wheel body 104, and further comprises:

[0036] A rotating assembly for rotating the bucket wheel body 104 is arranged on the cantilever 102, and a sealing and dustproof assembly for sealing and dustproofing the feed port on the bucket 105 after taking materials is arranged on each group of hoppers 105, and an S-shaped conveying cover 4 for stable conveying after taking materials is arranged between the bucket wheel body 104 and the conveyor belt 103, one end of the S-shaped conveying cover 4 is located above the conveyor belt 103 and is provided with an intermittent discharging assembly for intermittent control of discharging, a buffer plate 6 for buffering after feeding is arranged inside the S-shaped conveying cover 4, a lifting assembly for lifting and lowering the buffer plate 6 is arranged on the S-shaped conveying cover 4, and a vibration assembly for assisting the stable conveying of materials inside the S-shaped conveying cover 4 is arranged below the S-shaped conveying cover 4, and a control assembly for controlling the discharging after taking materials is arranged between each group of hoppers 105 and the bucket wheel body 104;

[0037] The rotating assembly includes a support frame 201 fixed to the cantilever 102, an S-shaped conveying cover 4 is fixed to the upper end of the support frame 201, a rotating shaft 202 is rotatably connected to the support frame 201, one end of the rotating shaft 202 is fixed to the bucket wheel body 104, and the bucket wheel body 104 and the rotating shaft 202 are concentrically arranged, and a driving motor 203 for driving the rotating shaft 202 is installed on one side of the cantilever 102;

[0038] It should be noted here that: during the operation of the bucket wheel stacker and reclaimer, the S-shaped conveying cover 4 and the buffer plate 6 cooperate with the sealing and dust-proof components, the intermittent discharging components, the control components and other components, so that the materials falling into the S-shaped conveying cover 4 can be buffered, so as to prevent the materials from falling directly onto the conveyor belt 103 with a relatively high material difference, thereby reducing the impact on the conveyor belt 103 and avoiding a large amount of dust generated by the direct fall of materials during the material collection and transportation process. After the hopper 105 takes the materials, the front end and the bottom of the hopper 105 can be in a relatively blocked state, thereby reducing the probability of the materials in the hopper 105 shaking after taking the materials and generating dust and overflowing, thereby ensuring the dust-proof effect of the bucket wheel stacker and reclaimer during operation.

[0039] Preferably, the blocking and dust-proof assembly includes two groups of symmetrically arranged first mounting shafts 301 rotatably connected to the hopper 105, and the two groups of first mounting shafts 301 are fixed with blocking plates 302 for blocking the hopper 105, one end of the first mounting shaft 301 is fixed to the circular baffle 303, and the outer side of the first mounting shaft 301 is sleeved with a torsion spring 304, and the two ends of the torsion spring 304 are respectively connected to the outer side of the hopper 105 and the circular baffle 303, and two groups of positioning baffles 305 for positioning the blocking plate 302 are fixed to the inner side of the hopper 105;

[0040] It should be noted here that: in the process of the hopper 105 taking materials by the rotation of the bucket wheel body 104, when the hopper 105 cuts into the material, the material and the two sets of sealing plates 302 are pressed against each other, pushing the two sets of sealing plates 302 to rotate toward the inside of the hopper 105 and allowing part of the material to enter the inside of the hopper 105. As the bucket wheel body 104 continues to rotate, the hopper 105 after taking the material is no longer against the material pile. At this time, the two sets of sealing plates 302 are reset through the elastic force of the torsion spring 304 and the rotation connection of the first mounting shaft 301, and the reset sealing plates 302 are positioned against each other through the positioning baffle 305. The interior of the hopper 105 is shielded and protected by the resetting of the two sets of sealing plates 302 to prevent the hopper 105 from being in an open state after taking the material and generating dust and overflowing with the rotation of the bucket wheel body 104.

[0041] Preferably, the control assembly includes an annular plate 501 rotatably connected to the inner side of the bucket wheel body 104, the annular plate 501 is provided with a through slot 502 for communicating with the inside of the hopper 105, the other end of the S-shaped conveying cover 4 is fixed to the inside of the annular plate 501 and communicates with the through slot 502, and the inside of each group of hoppers 105 is rotatably connected with a second mounting shaft 503, and the second mounting shaft 503 is fixed with a flip plate 504 for carrying the material after entering the hopper 105;

[0042] It should be noted here that: after the hopper 105 finishes taking materials, the flip plate 504 inside the hopper 105 is offset against the outer side of the annular plate 501 to support the materials that fall in. As the bucket wheel body 104 continues to rotate, when the flip plate 504 inside the hopper 105 is connected to the inside of the through slot 502, the flip plate 504 is no longer supported and the gravity of the materials inside the hopper 105 pushes the flip plate 504 to flip toward the inside of the through slot 502. Through the flipping of the flip plate 504, the materials that enter the hopper 105 fall into the S-shaped conveying cover 4, completing the conveying of the materials after taking materials.

[0043] Preferably, the gap discharge assembly includes square grooves 801 symmetrically opened on both sides of the S-shaped conveying cover 4, and two groups of square grooves 801 are slidably connected with strip baffles 802 for discharging blocking, and the outer side of the S-shaped conveying cover 4 is provided with a transmission assembly for transmitting the two groups of strip baffles 802 and a guide assembly for guiding during the transmission process;

[0044] It should be noted here that: through transmission, the two groups of strip baffles 802 are driven to reciprocate towards or away from each other on the S-shaped conveying cover 4. Through the reciprocating movement of the two groups of strip baffles 802, the discharge of the S-shaped conveying cover 4 is intermittently blocked and controlled to avoid the continuous excessive discharge of the S-shaped conveying cover 4 from causing impact on the conveyor belt 103, and through the intermittent control of the discharge of the S-shaped conveying cover 4, dust overflow caused by excessive one-time discharge is again avoided, thereby ensuring the dust prevention effect.

[0045] Preferably, the transmission assembly includes a transmission plate 1001 arranged on the outside of the S-shaped conveying cover 4, a telescopic assembly for telescopically connecting the transmission plate 1001 is arranged on the outside of the S-shaped conveying cover 4, two groups of symmetrically arranged inclined grooves 1002 are opened on the transmission plate 1001, and transmission pins 1003 are slidably connected to the two groups of inclined grooves 1002, and the two groups of transmission pins 1003 are respectively fixed to one side of the two groups of strip baffles 802, and a pushing assembly for pushing the transmission plate 1001 is arranged on the rotating shaft 202; the pushing assembly includes a driving disk 1201 fixed to the outside of the rotating shaft 202, and a plurality of extrusion pins 1202 for pressing the transmission plate 1001 against each other are fixed on the outside of the driving disk 1201 in a state of an annular array;

[0046] It should be noted here that: the driving disk 1201 is driven to rotate by the rotation of the rotating shaft 202. During the rotation of the driving disk 1201, the transmission plate 1001 is caused to reciprocate up and down with the rotation of the rotating shaft 202 through the mutual extrusion effect of each group of extrusion pins 1202 and the transmission plate 1001 in turn and the resetting effect of the telescopic component on the transmission plate 1001 after movement. During the movement of the transmission plate 1001, the two groups of strip baffles 802 are driven to reciprocate towards or away from each other on the S-shaped conveying cover 4 through the interaction between the two groups of inclined grooves 1002 and the two groups of transmission pins 1003 respectively.

[0047] Preferably, the guide assembly includes two groups of connection blocks 901 fixed on the strip baffle 802, and the two groups of connection blocks 901 are slidably connected with T-shaped rods 902, and one end of the T-shaped rod 902 is fixed to the outer side of the S-shaped conveying cover 4;

[0048] It should be noted here that the connecting block 901 and the T-shaped rod 902 are used to facilitate the guiding movement of the strip baffle 802 after being assisted by force.

[0049] Preferably, two groups of telescopic components are symmetrically arranged, and the telescopic components include a fixed block 1101 fixed to the outside of the S-shaped conveying cover 4, a first sleeve 1102 is fixed to the fixed block 1101, a first slide bar 1103 is slidably connected to the first sleeve 1102, one end of the first slide bar 1103 is fixed to the transmission plate 1001, and a spring 1104 is sleeved on the outside of the first sleeve 1102, and both ends of the spring 1104 are respectively connected to the fixed block 1101 and the transmission plate 1001;

[0050] It should be noted here that: the first sleeve 1102 and the first slide bar 1103 facilitate the extension and retraction guidance of the transmission plate 1001 after being stressed, and the spring 1104 facilitates the reset of the transmission plate 1001 after movement.

[0051] Preferably, the lifting assembly includes a U-shaped frame 701 fixed to the upper end of the S-shaped conveying cover 4, a threaded tube 702 is slidably connected to the S-shaped conveying cover 4, one end of the threaded tube 702 is fixed to the buffer plate 6, a threaded rod 703 is rotatably connected to the U-shaped frame 701, the threaded rod 703 is threadedly engaged with the threaded tube 702, and a mounting motor 704 for driving the threaded rod 703 is installed on the U-shaped frame 701, two groups of second sleeves 705 are slidably connected to the S-shaped conveying cover 4, the two groups of second sleeves 705 are symmetrically arranged on both sides of the threaded tube 702, one end of the second sleeve 705 is fixed to the buffer plate 6, and a second slide bar 706 is slidably connected to the second sleeve 705, and one end of the second slide bar 706 is fixed to the U-shaped frame 701;

[0052] It should be noted here that: the threaded rod 703 is driven to rotate by installing a motor 704. During the rotation of the threaded rod 703, the mutual meshing transmission between the threaded rod 703 and the threaded tube 702 and the sliding guiding effect of the second sleeve 705 and the second slide rod 706 are used to make the buffer plate 6 rise and fall after being subjected to force. By lifting and lowering the buffer plate 6, the gap between the bottom of the buffer plate 6 and the inside of the S-shaped conveying cover 4 is adjusted. The adjustment of the gap facilitates the control of the discharge flow rate after buffering.

[0053] Preferably, the vibration assembly includes a mounting plate 1301 disposed below the S-shaped conveying cover 4, and a plurality of groups of rubber protrusions 1302 for abutting and squeezing the S-shaped conveying cover 4 are fixed on the outer side of the mounting plate 1301 in a circular array, and a driving assembly for driving the mounting plate 1301 is disposed on the support frame 201;

[0054] It should be noted here that: the mounting disk 1301 is rotated by the driving assembly. During the rotation of the mounting disk 1301, each group of rubber protrusions 1302 is sequentially abutted against the lower end of the S-shaped conveying hood 4, causing the S-shaped conveying hood 4 to vibrate against each other. Through the vibration effect, the material inside the S-shaped conveying hood 4 is facilitated to be stably conveyed.

[0055] The driving assembly includes a driving shaft 1402 rotatably connected to the support frame 201, the mounting plate 1301 is fixed to one end of the driving shaft 1402, and a first gear 1401 and a second gear 1403 are respectively fixed to the rotating shaft 202 and the driving shaft 1402, and the first gear 1401 and the second gear 1403 are meshed with each other;

[0056] It should be noted here that: during the rotation of the rotating shaft 202, the first gear 1401 is driven to rotate. During the rotation of the first gear 1401, the mutual meshing transmission between the first gear 1401 and the second gear 1403 causes the drive shaft 1402 and the mounting plate 1301 on the drive shaft 1402 to rotate.

[0057] In this scheme: a dust prevention device for a bucket wheel stacker and reclaimer comprises the following steps:

[0058] During the operation of the bucket wheel stacker and reclaimer, the bucket wheel body 104 on one side of the cantilever 102 is moved to the position where the material needs to be taken through the movement of the machine body 101. After the movement is completed, the rotating shaft 202 and the bucket wheel body 104 at one end of the rotating shaft 202 are driven to rotate by the driving motor 203. During the rotation of the bucket wheel body 104, each group of hoppers 105 cuts into the material pile and collects part of the material into the hopper 105. As the bucket wheel body 104 continues to rotate and the control component controls the hopper 105, the material collected in the hopper 105 falls into the S-shaped conveying cover 4 and is conveyed through the S-shaped conveying cover 4. The cover 4 guides the material conveying, so that the material finally falls onto the conveyor belt 103, and cooperates with the conveyor belt 103 to convey the material to complete the material picking operation. In the process of picking up the material through the S-shaped conveyor cover 4, because the S-shaped conveyor cover 4 is arranged in an S shape, the material falling into the S-shaped conveyor cover 4 can be buffered through the shape of the S-shaped conveyor cover 4 and the buffer plate 6 inside the S-shaped conveyor cover 4, so as to prevent the material from falling directly onto the conveyor belt 103 with a relatively high material difference, reduce the impact on the conveyor belt 103, and avoid a large amount of dust generated by the direct fall of the material during the material picking and conveying process, so as to achieve a dust prevention effect;

[0059] In the process of the bucket wheel body 104 rotating to make the hopper 105 take the material, when the hopper 105 cuts into the material, the material and the two sets of blocking plates 302 are pressed against each other, pushing the two sets of blocking plates 302 to rotate toward the inside of the hopper 105 and allowing part of the material to enter the inside of the hopper 105. As the bucket wheel body 104 continues to rotate, the hopper 105 after taking the material is no longer pressed against the material pile. At this time, the elastic force of the torsion spring 304 and the rotation connection of the first mounting shaft 301 are used to reset the two sets of blocking plates 302 and the reset blocking plates 302 are pressed against each other by the positioning baffle 305. The reset of 302 shields and protects the inside of the hopper 105, so as to prevent the hopper 105 from being in an open state after taking materials and generating dust and overflowing with the rotation of the bucket wheel body 104. After the hopper 105 takes materials, the internal flip plate 504 of the hopper 105 and the outer side of the annular plate 501 are counteracted to support the materials that fall into the hopper. With the continuous rotation of the bucket wheel body 104, when the flip plate 504 inside the hopper 105 is connected with the inside of the through slot 502, the flip plate 504 is no longer supported and the gravity of the materials inside the hopper 105 pushes the flip plate 504 to flip toward the inside of the through slot 502 (see FIG. Figure 6The material in the hopper 105 is in the S-shaped conveying cover 4, and the material after taking the material is transported. In the whole process of transport control, the front end and the bottom of the hopper 105 are in a relatively blocked state, which reduces the probability of dust generated by the shaking of the material after taking the material in the hopper 105 and the overflow, and ensures the dust prevention effect during the operation of the bucket wheel stacker and reclaimer. After the material in the hopper 105 is transported to the inside of the S-shaped conveying cover 4, as the bucket wheel body 104 continues to rotate, the flip plate 504 is abutted against the inner wall of the through slot 502, pushing the flip plate 504 to reset. The reset of the flip plate 504 facilitates the normal material taking and load-bearing support operation of the hopper 105.

[0060] And in the process of taking materials, the driving disk 1201 is driven to rotate by the rotation of the rotating shaft 202. In the process of the rotation of the driving disk 1201, the transmission plate 1001 is made to reciprocate up and down with the rotation of the rotating shaft 202 through the mutual extrusion effect of each group of extrusion pins 1202 and the transmission plate 1001 in turn and the resetting effect of the telescopic component on the transmission plate 1001 after the movement, and the transmission plate 1001 is made to reciprocate up and down with the rotation of the rotating shaft 202. In the process of the movement of the transmission plate 1001, the two groups of inclined grooves 1002 interact with the two groups of transmission pins 1003 respectively, so as to drive the two groups of strip baffles 802 to reciprocate on the S-shaped conveying cover 4 to move towards or away from each other. Through the reciprocating motion of the two groups of strip baffles 802, the discharging of the S-shaped conveying cover 4 is intermittently blocked and controlled to avoid the continuous excessive discharging of the S-shaped conveying cover 4 from causing an impact on the conveyor belt 103, and through the intermittent control of the discharging of the S-shaped conveying cover 4, the dust overflow caused by excessive one-time discharging is avoided again, thereby ensuring the dust prevention effect.
