Description

Technical Field

[0001] The present invention relates to the technical field of bucket wheel stacker reclaimers, and particularly to a dust-proof device for a bucket wheel stacker reclaimer. Background Art

[0002] A bucket wheel stacker reclaimer is a large-scale continuous loading and unloading device, mainly used for the stacking and reclaiming operations of bulk materials (such as coal, ore, sand and gravel, etc.). It can realize the functions of efficient material stacking and reclaiming materials from the stockpile, and is a key device in the automatic process of bulk material handling.

[0003] During the use of the bucket wheel stacker reclaimer, due to the large falling material difference between the bucket wheel and the conveyor belt, the material after reclaiming will cause a strong impact on the conveyor belt when it falls onto the conveyor belt, which is likely to cause damage to the conveyor belt. At the same time, a large amount of dust will be generated. Moreover, after the bucket on the bucket wheel reclaims materials and rotates with the bucket wheel, the materials inside the bucket will shake and cause dust to overflow, affecting the working environment of the bucket wheel stacker reclaimer. For this reason, we propose a dust-proof device for a bucket wheel stacker reclaimer. Summary of the Invention

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figures 1 - 12 , a dust-proof device for a bucket wheel stacker-reclaimer shown in the figure, including a machine body 101, a cantilever 102 is installed on the machine body 101, a conveyor belt 103 for conveying after taking materials 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 fixedly arranged on the outer side of the bucket wheel body 104 in an annular array state. Each group of hoppers 105 is communicated with the inside of the bucket wheel body 104. It also includes:

[0036] A rotating assembly arranged on the cantilever 102 for rotating the bucket wheel body 104. A plugging and dust-proof assembly for plugging and dust-proofing the feeding port on the hopper 105 after taking materials is arranged on each group of hoppers 105. 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 controlling the intermittent discharging. A buffer plate 6 for buffering after feeding is arranged inside the S-shaped conveying cover 4. A lifting assembly for lifting the buffer plate 6 is arranged on the S-shaped conveying cover 4. A vibration assembly for assisting the stable conveying of the materials inside the S-shaped conveying cover 4 is arranged below the S-shaped conveying cover 4. 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. The 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. 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-reclaimer, through the mutual cooperation of the S-shaped conveying cover 4, the buffer plate 6, and components such as the plugging and dust-proof component, the intermittent discharging component, and the control component, the materials falling into the inside of the S-shaped conveying cover 4 can be buffered, avoiding the direct fall of the materials onto the conveyor belt 103 with a relatively large material difference, reducing the impact on the conveyor belt 103, and at the same time avoiding a large amount of dust generated by the direct fall of the materials during the material-taking and conveying process. After the hopper 105 takes materials, the front end and the bottom of the hopper 105 can be in a relatively plugged state, reducing the probability of dust generated by the shaking of the materials in the hopper 105 after taking materials and overflowing, and ensuring the dust-proof effect during the operation of the bucket-wheel stacker-reclaimer.

[0039] Preferably, the plugging and dust-proof component includes two groups of symmetrically arranged first mounting shafts 301 rotatably connected to the hopper 105. A plugging plate 302 for plugging the hopper 105 is fixed on the two groups of first mounting shafts 301. One end of the first mounting shaft 301 is fixed to a circular baffle 303. A torsion spring 304 is sleeved outside the first mounting shaft 301. The two ends of the torsion spring 304 are respectively connected to the outside of the hopper 105 and the circular baffle 303. Two groups of positioning baffles 305 for positioning the plugging plate 302 are fixed inside the hopper 105.

[0040] It should be noted here that during the process of the hopper 105 taking materials by the rotation of the bucket-wheel body 104, when the hopper 105 cuts into the materials, through the mutual abutting and squeezing action of the materials and the two groups of plugging plates 302, the two groups of plugging plates 302 are pushed to rotate towards the inside of the hopper 105 and part of the materials enter the inside of the hopper 105. As the bucket-wheel body 104 continues to rotate, the hopper 105 after taking materials no longer abuts against the material pile. At this time, through the elastic force of the torsion spring 304 and the rotational connection of the first mounting shaft 301, the two groups of plugging plates 302 are reset and the reset plugging plates 302 are abutted and positioned by the positioning baffles 305. The inside of the hopper 105 is shielded and protected by the reset of the two groups of plugging plates 302, avoiding the generation and overflow of dust due to the open state of the hopper 105 after taking materials along with the rotation of the bucket-wheel body 104.

[0041] Preferably, the control component includes an annular plate 501 rotatably connected to the inside of the bucket-wheel body 104. A through groove 502 for communicating with the inside of the hopper 105 is opened on the annular plate 501. The other end of the S-shaped conveying cover 4 is fixed inside the annular plate 501 and communicates with the through groove 502. A second mounting shaft 503 is rotatably connected to the inside of each hopper 105. A turning plate 504 for carrying the materials entering the inside of the hopper 105 is fixed on the second mounting shaft 503.

[0042] It should be noted here that after the hopper 105 finishes taking materials, through the abutting action between the inner turning plate 504 of the hopper 105 and the outer side of the annular plate 501, the falling materials are carried and supported. Along with the continuous rotation of the bucket wheel body 104, when the inner turning plate 504 of the hopper 105 communicates with the inside of the through slot 502, at this time, the support for the turning plate 504 is no longer provided, and under the action of the gravity of the materials inside the hopper 105, the turning plate 504 is pushed to turn towards the inside of the through slot 502. Through the turning of the turning plate 504, the materials entering the hopper 105 fall into the inside of the S-shaped conveying cover 4, completing the conveying of the materials after taking.

[0043] Preferably, the intermittent discharging assembly includes square grooves 801 symmetrically opened on both sides of the S-shaped conveying cover 4. A strip-shaped baffle 802 for discharging blockage is slidably connected to the two groups of square grooves 801. A transmission assembly for driving the two groups of strip-shaped baffles 802 and a guiding assembly for guiding during the transmission process are arranged outside the S-shaped conveying cover 4;

[0044] It should be noted here that through transmission, the two groups of strip-shaped baffles 802 are driven to perform reciprocating motions of approaching or separating from each other on the S-shaped conveying cover 4. Through the reciprocating motions of the two groups of strip-shaped baffles 802, the discharging on the S-shaped conveying cover 4 is intermittently blocked and controlled, avoiding excessive continuous discharging on the S-shaped conveying cover 4 from impacting the conveyor belt 103. And through the intermittent control of the discharging on the S-shaped conveying cover 4, it also avoids excessive dust overflow caused by excessive discharging at one time, ensuring the dust-proof effect.

[0045] Preferably, the transmission assembly includes a transmission plate 1001 arranged outside the S-shaped conveying cover 4. An expansion and contraction assembly for telescopically connecting the transmission plate 1001 is arranged outside the S-shaped conveying cover 4. Two groups of symmetrically arranged inclined grooves 1002 are opened on the transmission plate 1001. Transmission pins 1003 are slidably connected to the two groups of inclined grooves 1002. The two groups of transmission pins 1003 are respectively fixed to one side of the two groups of strip-shaped baffles 802. 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. A plurality of extrusion pins 1202 for abutting and extruding the transmission plate 1001 are fixed in an annular array on the outside of the driving disk 1201;

[0046] It should be noted here that: by the rotation of the rotating shaft 202, the driving disc 1201 is driven to rotate. During the rotation of the driving disc 1201, through the abutting and squeezing actions of each group of squeezing pins 1202 against the transmission plate 1001 in sequence and the resetting action of the telescopic assembly on the transmission plate 1001 after movement, the transmission plate 1001 makes an up-and-down reciprocating movement along with the rotation of the rotating shaft 202. During the movement of the transmission plate 1001, through the interaction between the two inclined slots 1002 and the two transmission pins 1003 respectively, the two strip-shaped baffles 802 are driven to make a reciprocating movement of approaching or separating from each other on the S-shaped conveying cover 4.

[0047] Preferably, the guiding assembly includes two connecting blocks 901 fixed on the strip-shaped baffle 802. A T-shaped rod 902 is slidably connected to the two connecting blocks 901, and one end of the T-shaped rod 902 is fixed to the outside of the S-shaped conveying cover 4;

[0048] It should be noted here that: through the connecting block 901 and the T-shaped rod 902, it is convenient to assist the guiding movement of the strip-shaped baffle 802 after being stressed.

[0049] Preferably, two groups of telescopic assemblies are symmetrically arranged. The telescopic assembly includes a fixed block 1101 fixed on the outside of the S-shaped conveying cover 4. A first sleeve 1102 is fixed on the fixed block 1101. A first sliding rod 1103 is slidably connected to the first sleeve 1102. One end of the first sliding rod 1103 is fixed to the transmission plate 1001. A spring 1104 is sleeved on the outside of the first sleeve 1102, and both ends of the spring 1104 are connected to the fixed block 1101 and the transmission plate 1001 respectively;

[0050] It should be noted here that: through the first sleeve 1102 and the first sliding rod 1103, it is convenient to conduct telescopic guiding on the transmission plate 1001 after being stressed. Through the spring 1104, it is convenient for the transmission plate 1001 to reset after movement.

[0051] Preferably, the lifting assembly includes a U-shaped frame 701 fixed on the upper end of the S-shaped conveying cover 4. A threaded pipe 702 is slidably connected to the S-shaped conveying cover 4. One end of the threaded pipe 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 in threaded engagement with the threaded pipe 702. An installation motor 704 for driving the threaded rod 703 is installed on the U-shaped frame 701. Two second sleeves 705 are slidably connected to the S-shaped conveying cover 4. The two second sleeves 705 are symmetrically arranged on both sides of the threaded pipe 702. One end of the second sleeve 705 is fixed to the buffer plate 6. A second sliding rod 706 is slidably connected to the second sleeve 705. One end of the second sliding rod 706 is fixed to the U-shaped frame 701;

[0052] It should be noted here that: by installing the motor 704 to drive the threaded rod 703 to rotate, during the rotation of the threaded rod 703, through the meshing transmission between the threaded rod 703 and the threaded tube 702 and the sliding guiding action of the second sleeve 705 and the second sliding rod 706, the buffer plate 6 after being stressed is lifted and lowered. Through the lifting and lowering of 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, and the discharge flow rate after buffering is conveniently controlled through the adjustment of the gap.

[0053] Preferably, the vibration assembly includes a mounting plate 1301 disposed below the S-shaped conveying cover 4. A plurality of rubber protrusions 1302 for abutting and pressing against the S-shaped conveying cover 4 are fixedly arranged in an annular array on the outer side of the mounting plate 1301. A driving assembly for driving the mounting plate 1301 is provided on the support frame 201;

[0054] It should be noted here that: through the driving assembly, the mounting plate 1301 is rotated. During the rotation of the mounting plate 1301, each group of rubber protrusions 1302 abuts against the lower end of the S-shaped conveying cover 4 in turn, causing the S-shaped conveying cover 4 to vibrate by abutting. Through the vibration effect, the stable conveying operation of the materials inside the S-shaped conveying cover 4 is facilitated.

[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. A first gear 1401 and a second gear 1403 are respectively fixed on 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, through the meshing transmission between the first gear 1401 and the second gear 1403, the driving shaft 1402 and the mounting plate 1301 on the driving shaft 1402 are rotated.

[0057] In this solution: a dust-proof device for a bucket wheel stacker-reclaimer includes the following steps:

[0058] During the operation of the bucket-wheel stacker-reclaimer, through the movement of the machine body 101, the bucket-wheel body 104 on one side of the boom 102 is moved to the position where material needs to be retrieved. After the movement is completed, the drive motor 203 drives the rotary shaft 202 and the bucket-wheel body 104 at one end of the rotary shaft 202 to rotate. During the rotation of the bucket-wheel body 104, each group of hoppers 105 cuts into the material pile, and part of the material is collected into the interior of the hopper 105. With the continuous rotation of the bucket-wheel body 104 and the control of the control component, the material collected inside the hopper 105 falls into the interior of the S-shaped conveying cover 4. Through the conveying and guiding effect of the S-shaped conveying cover 4 on the material, the material finally falls onto the conveyor belt 103. Cooperating with the conveying function of the conveyor belt 103 on the material, the operation of retrieving the material is completed. During the process of retrieving the material through the S-shaped conveying cover 4, since the S-shaped conveying cover 4 is arranged in an S shape, through the shape of the S-shaped conveying cover 4 and the buffering plate 6 inside the S-shaped conveying cover 4, the material falling into the interior of the S-shaped conveying cover 4 can be buffered, avoiding the material falling directly onto the conveyor belt 103 with a relatively large material difference, reducing the impact on the conveyor belt 103, and at the same time avoiding a large amount of dust generated by the direct falling of the material during the material retrieval and conveying process, achieving a dust-proof effect;

[0059] During the process of the hopper 105 retrieving the material through the rotation of the bucket-wheel body 104, when the hopper 105 cuts into the material, through the mutual extrusion effect of the material and the two blocking plates 302, the two blocking plates 302 are pushed to rotate towards the interior of the hopper 105 and part of the material enters the interior of the hopper 105. With the continuous rotation of the bucket-wheel body 104, the hopper 105 after retrieving the material no longer abuts against the material pile. At this time, through the elastic force of the torsion spring 304 and the rotational connection effect of the first mounting shaft 301, the two blocking plates 302 are reset and the reset blocking plates 302 are abutted and positioned by the positioning baffle 305. The interior of the hopper 105 is shielded and protected by the reset of the two blocking plates 302, avoiding the open state of the hopper 105 after retrieving the material from generating dust and overflowing along with the rotation of the bucket-wheel body 104. After the hopper 105 finishes retrieving the material, through the abutting effect between the turning plate 504 inside the hopper 105 and the outer side of the annular plate 501, the falling material is carried and supported. Along with the continuous rotation of the bucket-wheel body 104, when the turning plate 504 inside the hopper 105 communicates with the inside of the through slot 502, at this time, the support for the turning plate 504 is no longer provided and through the gravity of the material inside the hopper 105, the turning plate 504 is pushed to turn towards the inside of the through slot 502 (see Figure 6State), by flipping the flipping plate 504, the materials entering the inside of the hopper 105 fall into the inside of the S-shaped conveying cover 4, completing the conveying of the materials after material taking. During the entire conveying control process, the front end and the bottom of the hopper 105 are in a relatively blocked state, reducing the probability of dust generated by the shaking of the materials in the hopper 105 after material taking and overflowing, ensuring the dust prevention effect during the operation of the bucket wheel stacker-reclaimer. After the materials inside the hopper 105 are conveyed towards the inside of the S-shaped conveying cover 4, as the bucket wheel body 104 continues to rotate, the flipping plate 504 abuts against the inner wall of the through groove 502, pushing the flipping plate 504 to reset. Through the reset of the flipping plate 504, it is convenient for the hopper 105 to take materials normally and carry out supporting operations;

[0060] And during the material taking process, by rotating the rotating shaft 202, the driving disk 1201 is driven to rotate. During the rotation of the driving disk 1201, through the abutting and squeezing actions of each group of extrusion pins 1202 against the transmission plate 1001 in sequence and the resetting action of the telescopic assembly on the transmission plate 1001 after movement, the transmission plate 1001 makes a reciprocating up and down movement as the rotating shaft 202 rotates. During the movement of the transmission plate 1001, through the interaction between the two inclined grooves 1002 and the two transmission pins 1003 respectively, the two strip-shaped baffles 802 are driven to make a reciprocating movement of approaching or separating from each other on the S-shaped conveying cover 4. Through the reciprocating movement of the two strip-shaped baffles 802, the intermittent blocking control of the discharging on the S-shaped conveying cover 4 is carried out, avoiding the impact on the conveyor belt 103 caused by excessive continuous discharging on the S-shaped conveying cover 4. And through the intermittent control of the discharging on the S-shaped conveying cover 4, it is again avoided that excessive discharging at one time generates dust overflow, ensuring the dust prevention effect.
