Description

Technical Field

[0001] This invention belongs to the field of bucket wheel reclaimers. Background Technology

[0002] In the continuous material reclaiming process of a bucket wheel reclaimer, each bucket rotates with the annular bucket wheel. Each time a bucket rotates with the annular bucket wheel and its feed inlet faces upwards, the sharp blades of that bucket scoop upwards to remove the material, bringing it into the bucket cavity. In mining, soil, and other material reclaiming scenarios, due to the diversity of the materials being reclaimed, such as... Figure 2 As shown, the material reaching the bucket may be in clumps 61, which get stuck between the two side walls of the bucket. When the bucket rotates to the top of the bucket wheel, the clumps 61 stuck between the two side walls of the bucket will not fall down under the action of gravity, thus causing the problem of low material handling efficiency. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an anti-jamming bucket wheel for a bucket wheel reclaimer, which solves the problem of clumps of material getting stuck between the two side walls inside the bucket.

[0004] Technical solution: To achieve the above objectives, the present invention provides an anti-jamming bucket wheel for a bucket wheel reclaimer, comprising an annular bucket wheel body, on which a plurality of buckets are fixedly installed in a circumferential array; the buckets are composed of an arc-shaped back and bucket side plates on both sides of the arc-shaped back, and an arc-shaped hollow groove is provided in the middle of the arc-shaped back of the bucket along the length direction, and an arc-shaped anti-jamming strip is provided in the arc-shaped hollow groove along the length direction.

[0005] Furthermore, when the bucket is in the material-shoveling state, the feed inlet of the bucket faces upward; a blade holder is fixedly installed at one end of the curved back of the bucket near the feed inlet, and a sharp blade is installed on the side of the blade holder near the feed inlet.

[0006] Furthermore, the end of the curved shovel back away from the tool holder has a shaft sleeve, and one end of the curved anti-jamming strip is fixedly connected to a transverse rotating shaft. The shaft sleeve is provided with a shaft hole, and the transverse rotating shaft is coaxially rotatably disposed in the shaft hole. Torsion springs are provided in the two shaft holes. The torsion springs apply a clockwise torque to the transverse rotating shaft, causing the curved anti-jamming strip to tend to swing clockwise around the transverse rotating shaft. Under normal conditions, under the clockwise torque of the torsion spring, the end of the curved anti-jamming strip is limited and overlapped on the inside of the tool holder.

[0007] Furthermore, a chute is provided inside the annular bucket wheel body. The upper end of the chute is the receiving port, and the lower end is the lateral discharge port. When each bucket rotates with the annular bucket wheel body to the position directly above the receiving port, the material in the bucket is poured downwards to the receiving port.

[0008] Furthermore, a blade-shaped lever arm is vertically connected to the side of the transverse rotating shaft away from the arc-shaped anti-jamming strip; a frame body is integrally set on the feed inlet profile of the chute;

[0009] When the bucket rotates counterclockwise with the annular bucket wheel to directly above the receiving port, the lower contour of the blade-shaped lever arm on the bucket contacts the right beam of the frame body, forming motion interference. As the bucket continues to rotate counterclockwise with the annular bucket wheel body, the right beam of the frame body applies an upward thrust to the blade-shaped lever arm, thereby causing the arc-shaped anti-jamming strip to overcome the clockwise torque of the torsion spring and swing counterclockwise downward around the transverse axis.

[0010] Furthermore, the contour edge of the two bucket side plates near the bucket wheel shaft is an arc edge, and the center of the arc edge is on the axis of the bucket wheel shaft; an arc baffle is fixedly connected to one side of the chute through a connecting arm, and the arc axis of the arc baffle coincides with the axis of the bucket wheel shaft.

[0011] When the bucket is positioned on the side of the annular bucket wheel and the bucket's feed inlet is facing upwards, the outer arc surface of the circular baffle slides or gap-fits with the circular edges of the two bucket side plates, and the arc-shaped back of the bucket, the two bucket side plates, and the outer arc surface of the circular baffle together form the bucket cavity.

[0012] Furthermore, when the bucket reaches the upper part of the annular bucket wheel body, the two bucket side plates of the bucket separate from the outer arc surface of the fixed arc baffle, and at this time the bucket cavity between the two bucket side plates is connected below.

[0013] Furthermore, the center of the arc-shaped baffle has an arc-shaped slit cut out along its length. When the bucket is in the right position of the annular bucket wheel, the blade-shaped lever arm on the bucket passes through the arc-shaped slit.

[0014] Beneficial effects: In the event that the material in the bucket cavity between the two bucket side plates is a non-loose clump of material, and this clump of material is stuck in the bucket cavity between the two bucket side plates and cannot fall down, as the bucket continues to rotate counterclockwise with the annular bucket wheel, the right beam of the frame applies an upward thrust to the blade-shaped lever arm, thereby causing the arc-shaped anti-jamming strip to overcome the clockwise torque of the torsion spring and swing counterclockwise downward around the transverse axis. The downward swinging anti-jamming strip applies a downward forced thrust to the clump of material stuck between the two bucket side plates, allowing the clump of material to fall down smoothly, thus solving the problem of clumps of material getting stuck between the two bucket side plates.

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] As attached Figures 1 to 6 The image shows an anti-jamming bucket wheel for a bucket wheel reclaimer, such as... Figure 1 and 3 The system includes an annular bucket wheel body 7 and a bucket wheel shaft 3. The annular bucket wheel body 7 is coaxially and fixedly connected to the bucket wheel shaft 3 via a bucket wheel bracket 8. The bucket wheel shaft 3 is rotatably mounted on the bucket wheel shaft bracket 2 via bearings. A drive device drives the bucket wheel shaft 3 to rotate actively. Several buckets 11 are fixedly mounted in a circular array on the annular bucket wheel body 7. The drive device drives the annular bucket wheel body 7 to rotate continuously counterclockwise. At the same time, each bucket 11 continues to rotate counterclockwise with the annular bucket wheel body 7. Each time the bucket 11 rotates with the annular bucket wheel body... When the ring-shaped bucket wheel 7 rotates to the right side, the sharp blades 13 of the bucket 11 scoop the material upwards; a chute 6 is provided on the inner side of the ring-shaped bucket wheel 7, and the chute 6 is fixed on the chute support 1; the upper end of the chute 6 is the receiving port 24, and the lower end is the side discharge port 9; when each bucket 11 rotates with the ring-shaped bucket wheel 7 to directly above the receiving port 24, the material in the bucket 11 is poured downwards to the receiving port 24; and finally discharged to the material conveying device through the side discharge port 9.

[0023] The bucket 11 is composed of an arc-shaped back 14 and bucket side plates 5 on both sides of the arc-shaped back 14. When the bucket 11 is in the shoveling state, the feed port 4 of the bucket 11 faces upward. A blade holder 12 is fixedly installed at one end of the arc-shaped back 14 near the feed port 4, and a sharp blade 13 is installed on the side of the blade holder 12 near the feed port 4. The contour edge of the two bucket side plates 5 near the bucket wheel shaft 3 is a rounded edge 44, and the center of the rounded edge 44 is on the axis of the bucket wheel shaft 3. A rounded baffle 52 is fixedly connected to one side of the chute 6 through a connecting arm 43, and the arc axis of the rounded baffle 52 coincides with the axis of the bucket wheel shaft 3.

[0024] When the bucket 11 is located on the side of the annular bucket wheel body 7 and the feed inlet 4 of the bucket 11 is facing upward, the outer arc surface of the arc baffle 52 slides or gap-fits with the arc edge 44 of the two bucket side plates 5, and the arc back 14, the two bucket side plates 5 and the outer arc surface of the arc baffle 52 together form the bucket cavity.

[0025] When the bucket 11 reaches the upper position of the annular bucket wheel body 7, the two bucket side plates 5 of the bucket 11 separate from the outer arc surface of the fixed-position arc baffle 52, at which point the lower part of the bucket cavity between the two bucket side plates 5 is connected; as Figure 2and 5 .

[0026] The arc-shaped back 14 of the bucket 11 has an arc-shaped hollow groove 10 along its length in the middle. Two coaxial shaft cylinders 22 are provided on both sides of the arc-shaped back 14 away from the blade holder 12. An arc-shaped anti-jamming strip 16 is provided along its length in the arc-shaped hollow groove 10. A transverse rotating shaft 20 is fixedly connected to one end of the arc-shaped anti-jamming strip 16. A shaft hole 21 is provided on the side of the two shaft cylinders 22 that are close to each other. The two ends of the transverse rotating shaft 20 are coaxially rotatably disposed in the two shaft holes 21. A torsion spring 19 is provided in both shaft holes 21. The torsion spring 19 applies a clockwise torque to the transverse rotating shaft 20, causing the arc-shaped anti-jamming strip 16 to swing clockwise around the transverse rotating shaft 20.

[0027] Under normal conditions, under the clockwise torque of the torsion spring 19, the end 16.1 of the arc-shaped anti-jamming strip 16 is limited and overlapped on the inner side of the cutter holder 12, thereby preventing the arc-shaped anti-jamming strip 16 from continuing to swing clockwise around the transverse rotating shaft 20; a blade-shaped lever arm 17 is vertically connected to the side of the transverse rotating shaft 20 away from the arc-shaped anti-jamming strip 16; each blade-shaped lever arm 17 is inside the ring of the annular bucket wheel body 7; a frame body 25 is integrally set on the outline of the feed inlet 4 of the chute 6; when the bucket 11 rotates counterclockwise with the annular bucket wheel body 7 to directly above the receiving port 24, if Figure 6 As shown, the lower profile 17.1 of the blade-shaped lever arm 17 on the bucket 11 contacts the right beam 25.1 of the frame body 25, forming motion interference. The bucket 11 continues to rotate counterclockwise with the annular bucket wheel body 7. The right beam 25.1 of the frame body 25 applies an upward thrust to the blade-shaped lever arm 17, thereby causing the arc-shaped anti-jamming strip 16 to overcome the clockwise torque of the torsion spring 19 and swing counterclockwise downward around the transverse pivot 20.

[0028] The arc-shaped baffle 52 has an arc-shaped slit 51 cut out along its length in the middle. The width of the arc-shaped slit 51 is greater than the width of the blade-shaped lever arm 17. When the bucket 11 is in the right position of the annular bucket wheel body 7, the blade-shaped lever arm 17 on the bucket 11 passes through the arc-shaped slit 51, thereby avoiding motion interference between the blade-shaped lever arm 17 and the arc-shaped baffle 52.

[0029] Working principle, analyzing the cycle of any bucket 11:

[0030] During operation, the drive device drives the annular bucket wheel 7 to rotate counterclockwise continuously. At the same time, each bucket 11 also rotates counterclockwise with the annular bucket wheel 7. Each time the bucket 11 rotates to the right side of the annular bucket wheel 7, the sharp blade 13 of the bucket 11 scoops up the material being taken. At this time, the arc edges 44 of the two bucket side plates 5 of the bucket 11 slide or gap fit with the outer arc surface of the arc baffle 52. The arc back 14, the two bucket side plates 5 and the outer arc surface of the arc baffle 52 together form a bucket cavity with the feed inlet 4 facing upward. The material scooped up by the sharp blade 13 of the bucket 11 falls into the bucket cavity with the feed inlet 4 facing upward, which is formed by the arc back 14, the two bucket side plates 5 and the outer arc surface of the arc baffle 52.

[0031] Subsequently, the bucket 11 continues to rotate counterclockwise with the annular bucket wheel 7. When the bucket 11 rotates counterclockwise with the annular bucket wheel 7 to directly above the receiving port 24, the lower contour 17.1 of the blade-shaped lever arm 17 on the bucket 11 contacts the right beam 25.1 of the frame 25, forming motion interference. At the same time, the two bucket side plates 5 of the bucket 11 are separated from the outer arc surface of the fixed-position arc baffle 52. The lower part of the bucket cavity between the two bucket side plates 5 is open, and the material in the bucket cavity between the two bucket side plates 5 inside the bucket 11 falls into the receiving port 24 of the chute 6 under the action of gravity, and is finally discharged to the material conveying device through the lateral discharge port 9. Meanwhile, if the material in the bucket cavity between the two bucket side plates 5 is a non-loose clump of material 61, and the clump of material 61 is stuck in the bucket cavity between the two bucket side plates 5 of the bucket 11 and cannot fall, such as Figure 2 As the bucket 11 continues to rotate counterclockwise with the annular bucket wheel body 7, the right beam 25.1 of the frame body 25 applies an upward thrust to the blade-shaped lever arm 17, causing the arc-shaped anti-jamming strip 16 to overcome the clockwise torque of the torsion spring 19 and swing counterclockwise downward around the transverse pivot 20. The downward swinging anti-jamming strip 16 applies a downward forced thrust to the clump of material 61 stuck between the two bucket side plates 5, allowing the clump of material 61 to fall smoothly, thus solving the problem of the clump of material 61 being stuck between the two bucket side plates 5.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
