Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to a material bucket elevator. Background Art

[0002] In the field of industrial production and material transportation, bucket elevators, as a key vertical conveying equipment, are widely used in the transportation of powdered and granular materials. It can effectively lift materials from a lower position to a higher position, meet the material height requirements of different production links, and ensure the continuity and efficiency of the production process.

[0003] The basic working principle of a bucket elevator is to carry and transport the materials put in from the feed port upwards through the hopper's cyclic movement along a specific conveying route in a closed casing. However, in the operation of existing bucket elevators, when materials are put in from the feed port, a strong impact will occur between the materials and the bucket at the moment of contact. This impact will not only damage the bucket itself, but long-term repeated impacts may cause the bucket to deform, wear, or even break, shortening the bucket's service life, increasing equipment maintenance costs and the frequency of bucket replacement. In addition, the vibration generated by the impact will be transmitted to the entire elevator system, which will affect the elevator's stability, increase the elevator's energy loss, and further increase the risk of equipment damage.

[0004] Chinese patent CN116374500B discloses a bulk building material conveying device. During the process of loading the hopper, the moving direction of the hopper is the same as the moving direction of the material, which reduces the relative speed between the hopper and the material, reduces the wear of the hopper, and increases the service life of the hopper. However, when discharging the material, the solution makes the opening of the bag face the discharge port, and the counterweight block flips the inner and outer surfaces of the bag, so that the material is discharged from the bag and discharged from the shell through the discharge port. In this process, the material is discharged in a dumping manner. The whole discharge process requires a large amount of power, and the material is easy to fall into the shell when dumping and accumulate at the bottom of the shell, affecting the normal transportation of the material.

DETAILED DESCRIPTION

[0030] 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.

[0031] An embodiment of a material bucket elevator of the present invention is as follows Figures 1 to 11 shown.

[0032] A material bucket elevator comprises a shell 100, a conveyor belt 200 and a plurality of hoppers 300. The shell 100 is arranged along a first direction, which is a vertical direction. The conveyor belt 200 is annular and can be installed in the shell 100 to rotate around a second direction, which is a horizontal direction. The plurality of hoppers 300 are fixedly arranged on the conveyor belt 200 and are evenly distributed along the winding direction of the conveyor belt 200. The upper and lower ends of the hoppers 300 can be opened or closed. A feed port 110 and a discharge port 120 are provided on the shell 100. The feed port 110 is located below the discharge port 120. The feed port 110 and the discharge port 120 are both located on the same side of the shell 100, and the material feeding direction and the material discharge direction are the same as the direction of the material conveyed by the conveyor belt 200 located on the same side.

[0033] The movement of the hopper 300 in the housing 100 includes a first stroke, a second stroke, and a third stroke. In the first stroke, the upper end of the hopper 300 is open and the lower end is closed. At this time, the material can enter from the feed port 110 and enter the hopper 300 from top to bottom. In the second stroke, both the upper and lower ends of the hopper 300 are closed. In the third stroke, the upper end of the hopper 300 is closed and the lower end is opened. At this time, the material can be discharged from the hopper 300 from top to bottom through the discharge port 120.

[0034] In this embodiment, a housing 100, a conveyor belt 200 and a plurality of hoppers 300 are provided. When in use, the conveyor belt 200 is driven to rotate about the second direction and drive the plurality of hoppers 300 to rotate synchronously, and then the material is put into the housing 100 from one side of the feed port 110. When the movement of the hopper 300 in the housing 100 is in the first stroke, the upper end of the hopper 300 is opened and the lower end is closed, and the material can enter from one side of the feed port 110 and enter the hopper 300 from top to bottom. Because the feeding direction of the material is the same as the direction in which the conveyor belt 200 on the same side conveys the material, when the material enters the housing 100 from the feed port 110, the material will enter the hopper 300 along the rotation direction of the hopper 300. See the attached drawing. Figure 2 As shown, and with Figure 2 The upper, lower, left and right sides are shown in the figure. The feed port 110 and the discharge port 120 are both opened on the right side of the housing 100. The conveyor belt 200 is shown in the attached figure. Figure 2, and one side of the conveyor belt 200 located on the same side as the feed port 110 and the discharge port 120 moves from top to bottom. By making the feeding direction of the material entering the hopper 300 from the feed port 110 the same as the movement direction of the hopper 300, the impact of the material entering the hopper 300 from the feed port 110 on the hopper 300 is weakened, the service life of the hopper 300 is extended, and the vibration and wear of the material bucket elevator are further reduced. The kinetic energy of the material can assist the movement of the hopper 300 to a certain extent, thereby relatively reducing the energy loss of the material bucket elevator and improving the stability of the material transportation process.

[0035] When the material enters the hopper 300, the movement of the hopper 300 in the housing 100 is in the second stroke, and the upper and lower ends of the hopper 300 are closed. Prevent the material from spilling during transportation. When the hopper 300 filled with the material moves to the discharge port 120 along the conveyor belt 200, the movement of the hopper 300 in the housing 100 is in the third stroke, the upper end of the hopper 300 is closed and the lower end is opened, and the material can be discharged from the hopper 300 from top to bottom through one side of the discharge port 120. During the movement of the hopper 300, the upper and lower ends of the hopper 300 are switched between open and closed, so that the hopper 300 can realize feeding or discharging, and ensure the stable transportation. That is, when it is necessary to receive materials, the upper end of the hopper 300 is opened and the lower end is closed, so that the hopper 300 receives the materials entering from the feed port 110. When it is necessary to discharge materials, the lower end of the hopper 300 is opened and the upper end is closed, so that the hopper 300 can discharge the materials from the discharge port 120, and try to avoid the materials falling into the shell 100. When feeding materials, the upper and lower ends of the hopper 300 are closed to avoid the materials from spilling during the transportation process. By continuously switching the movement of the hopper 300 between the first stroke, the second stroke and the third stroke, the material receiving, feeding and discharging processes are made more accurate and controllable, ensuring the stable transportation of materials.

[0036] In this embodiment, a top pulley 130 and a bottom pulley 140 are provided in the outer shell 100. Both the top pulley 130 and the bottom pulley 140 can rotate around the second direction. The top pulley 130 is located above the bottom pulley 140, and the conveyor belt 200 is sequentially wound around the top pulley 130 and the bottom pulley 140.

[0037] Specifically, a driving motor 400 is provided on the housing 100, and the top pulley 130 is fixedly installed at the output end of the driving motor 400. When in use, the driving motor 400 is started, and the bottom pulley 140 and the conveyor belt 200 are driven to rotate in the second direction through the top pulley 130.

Specifically, the upper cover 320 is hinged to the upper end of the shell 310, and the lower cover 330 is hinged to the lower end of the shell 310.

[0039] In this embodiment, the feed port 110 is tilted, and the feed port 110 has a first head end and a first tail end, the first head end is located above the first tail end, and the first head end is located on the side of the first tail end away from the conveyor belt 200 in the third direction, and the third direction is the radial direction of the rotation axis of the conveyor belt 200, so that the material can enter from the first head end and enter the hopper 300 from top to bottom through the first tail end. That is, the material can enter from the feed port 110 and enter the hopper 300 from top to bottom.

[0040] The discharge port 120 is arranged at an angle, and has a second head end and a second tail end, the second head end is located above the second tail end, and the second head end is located on the side of the second tail end close to the conveyor belt 200 in the third direction, so that the material can enter from the second head end and be discharged from the second tail end from top to bottom. That is, the material can be discharged from the discharge port 120 from top to bottom in the hopper 300.

[0041] In this embodiment, a guide plate 500 is provided in the housing 100. The guide plate 500 and the conveyor belt 200 are sequentially arranged in the second direction. A limit bar 501 is provided on the guide plate 500. The limit bar 501 is annular and is used to limit the rotation of the conveyor belt 200. A first slide rail 510 and a second slide rail 520 are provided on the guide plate 500. The upper cover 320 is slidably matched with the first slide rail 510, and the lower cover 330 is slidably matched with the second slide rail 520. The upper cover 320 slides along the first slide rail 510 to open or close the upper cover 320, and the lower cover 330 slides along the second slide rail 520 to open or close the lower cover 330.

[0042] Specifically, the upper cover 320 is provided with a first slide bar 321, which is arranged along the second direction and slidably installed in the first slide rail 510. The first slide rail 510 includes a first sliding section 511, a second sliding section 512 and a third sliding section 513. The first sliding section 511, the second sliding section 512 and the third sliding section 513 are sequentially arranged around the second direction on the guide plate 500 and are connected to each other. The two ends of the first sliding section 511 around the second direction are respectively referred to as the first end and the second end, the two ends of the second sliding section 512 around the second direction are respectively referred to as the third end and the fourth end, and the two ends of the third sliding section 513 around the second direction are respectively referred to as the fifth end and the sixth end.

[0043] That is, the conveyor belt 200 is shown in FIG. Figure 2 The direction shown in the figure is clockwise, and the direction closer to the clockwise arrow is called the front, and the direction farther from the clockwise arrow is called the rear. The front side and rear side here will continue to be used in the following description.

[0044] The first end is located at a side of the second end away from the conveyor belt 200 in the third direction, and the third end is located at a side of the fourth end close to the conveyor belt 200 in the third direction. The first end, the fourth end, the fifth end, and the sixth end are equidistant from the conveyor belt 200 in the third direction. When the first sliding bar 321 is at the first end, the fourth end, the fifth end, or the sixth end, the upper cover 320 is closed.

[0045] The lower cover 330 is provided with a second slide bar 331, which is arranged along the second direction and slidably installed in the second slide rail 520. The second slide rail 520 includes a fourth slide section 521, a fifth slide section 522 and a sixth slide section 523, which are arranged in sequence around the second direction on the guide plate 500 and are connected to each other. The two ends of the fourth slide section 521 around the second direction are respectively referred to as the seventh end and the eighth end, the two ends of the fifth slide section 522 around the second direction are respectively referred to as the ninth end and the tenth end, and the two ends of the sixth slide section 523 around the second direction are respectively referred to as the eleventh end and the twelfth end, and the seventh end, the eighth end, the ninth end, the tenth end, the eleventh end and the twelfth end are arranged in sequence in the rotation direction of the conveyor belt 200 and are connected to each other, and in the rotation direction of the conveyor belt 200, the seventh end is located behind the eighth end.

[0046] The seventh end is located at a side of the eighth end that is away from the conveyor belt 200 in the third direction, and the ninth end is located at a side of the tenth end that is close to the conveyor belt 200 in the third direction. The seventh end, the tenth end, the eleventh end, and the twelfth end are equidistant from the conveyor belt 200 in the third direction. When the second sliding bar 331 is at the seventh end, the tenth end, the eleventh end, or the twelfth end, the lower cover 330 is closed.

[0047] See attached Figure 6 and attached Figure 8 As shown, when the hopper 300 rotates to the downstream side of the feed port 110, the first slide bar 321 is located on the second end side of the first sliding section 511, and the hopper 300 is connected to the first tail end of the feed port 110, and the second slide bar 331 is located in the sixth sliding section 523.

[0048] See attached Figure 6 and attached Fig.10 As shown, when the hopper 300 rotates to the upstream side of the discharge port 120 , the second slide bar 331 is located on the eighth end side of the fourth sliding section 521 , and the lower cover 330 is connected to the second head end of the discharge port 120 , and the first slide bar 321 is located in the third sliding section 513 .

[0049] In this embodiment, by setting the first slide rail 510 and the second slide rail 520, when the conveyor belt 200 rotates in the second direction, the hopper 300 will be driven to rotate synchronously, and the first end of the first sliding section 511 is used as the starting point for explanation. At this time, the first slide bar 321 set on the upper cover 320 gradually slides toward the second end along the first end of the first sliding section 511. Since the first end is located on the side of the second end away from the conveyor belt 200 in the third direction, as the hopper 300 continues to move, the upper cover 320 will rotate relative to the shell 310 under the guidance of the first sliding section 511 and gradually open. When the first slide bar 321 slides to the side of the second end of the first sliding section 511, the hopper 300 rotates to the downstream side of the feed port 110, so that when the material enters from the feed port 110, the material can enter the hopper 300.

[0050] After the first slide bar 321 slides to the second end of the first slide section 511, the first slide bar 321 will come to the third end of the second slide section 512 (the second end and the third end can be regarded as two overlapping end points), and then the first slide bar 321 will gradually slide along the third end of the second slide section 512 to the fourth end, at which time the upper cover 320 will rotate relative to the housing 310 under the guidance of the second slide section 512, and gradually close to complete the material connection. In the above process, the second slide bar 331 of the lower cover 330 slides in the sixth slide section 523, so that the lower cover 330 remains closed. This is the first stroke of the movement of the hopper 300 in the housing 100.

[0051] After the first slide bar 321 slides to the fourth end of the second slide section 512, the first slide bar 321 will come to the fifth end of the third slide section 513 (the fourth end and the fifth end can be regarded as two overlapping end points), and then the first slide bar 321 will gradually slide along the fifth end of the third slide section 513 to the sixth end. During this process, the upper cover 320 remains in the closed state. The second slide bar 331 of the lower cover 330 slides in the sixth slide section 523, so that the lower cover 330 remains closed. This is the second stroke of the movement of the hopper 300 in the housing 100.

[0052] Until the second sliding bar 331 of the lower cover 330 slides to the twelfth end of the sixth sliding section 523, that is, the seventh end of the fourth sliding section 521 (the seventh end and the twelfth end can be regarded as two overlapping end points), then the second sliding bar 331 will gradually slide along the seventh end of the fourth sliding section 521 to the eighth end. Since the seventh end is located on the side of the eighth end away from the conveyor belt 200 in the third direction, as the hopper 300 continues to move, the lower cover 330 will rotate relative to the shell 310 under the guidance of the fourth sliding section 521 and gradually open. When the second sliding bar 331 slides to the eighth end of the fourth sliding section 521, the lower cover 330 is opened to the maximum. At this time, the hopper 300 rotates to the upstream side of the discharge port 120 to ensure that the material can be discharged from the hopper 300 to the discharge port 120, and try to avoid the material falling into the shell 100 to affect the normal transportation of the material.

[0053] When the second slide bar 331 slides to the eighth end of the fourth slide section 521, the second slide bar 331 will come to the ninth end of the fifth slide section 522 (the eighth end and the ninth end can be regarded as two overlapping end points), and then the second slide bar 331 will gradually slide along the ninth end of the fifth slide section 522 to the tenth end, at which time the lower cover 330 will rotate relative to the housing 310 under the guidance of the fifth slide section 522, and gradually close to complete the discharge. In the above process, the first slide bar 321 of the upper cover 320 slides in the third slide section 513, so that the upper cover 320 remains closed. This is the third stroke of the movement of the hopper 300 in the housing 100.

[0054] On the basis of ensuring that the material can enter the hopper 300 from the feed port 110 and can be discharged from the hopper 300 to the discharge port 120, when the hopper 300 rotates to the downstream side of the feed port 110, if the first slide bar 321 slides to the second end of the first slide section 511, the upper cover 320 can be opened to the maximum after the material enters from the feed port 110, ensuring that the material can enter the hopper 300. When the hopper 300 rotates to the upstream side of the discharge port 120, if the second slide bar 331 slides to the eighth end of the fourth slide section 521, the lower cover 330 is opened to the maximum at this time, which can increase the material discharge speed.

[0055] Furthermore, two guide plates 500 are provided, and the two guide plates 500 are respectively referred to as a first guide plate and a second guide plate. The first guide plate and the second guide plate are arranged side by side along the second direction in the housing 100 and are located on both sides of the conveyor belt 200 along the second direction.

[0056] The first guide plate and the second guide plate are both provided with a first slide rail 510 and a second slide rail 520. The first slide rail 510 on the first guide plate and the first slide rail 510 on the second guide plate are arranged face to face in the second direction. The second slide rail 520 on the first guide plate and the second slide rail 520 on the second guide plate are arranged face to face in the second direction. The upper cover 320 is provided with a first slide bar 321 at both ends along the second direction. The two first slide bars 321 are arranged in a one-to-one correspondence with the two first slide rails 510, and each first slide bar 321 is slidably installed in the first slide rail 510 corresponding to it. The lower cover 330 is provided with a second slide bar 331 at both ends along the second direction. The two second slide bars 331 are arranged in a one-to-one correspondence with the two second slide rails 520, and each second slide bar 331 is slidably installed in the second slide rail 520 corresponding to it.

[0057] In this embodiment, the first sliding rod 321 and the second sliding rod 331 are both columnar structures, the size of the first sliding rod 321 in the second direction is smaller than the size of the second sliding rod 331 in the second direction, the size of the first sliding rail 510 in the second direction is smaller than the size of the second sliding rail 520 in the second direction, and the diameter of the first sliding rod 321 is larger than the diameter of the second sliding rod 331.

[0058] Further, when the movement of the hopper 300 in the housing 100 is in the second stroke, the third sliding section 513 of the first slide rail 510 and the sixth sliding section 523 of the second slide rail 520 are arranged side by side in the second direction and are connected to each other.

[0059] That is, see Appendix Figure 7 As shown, when the movement of the hopper 300 in the housing 100 is in the second stroke, and the second slide bar 331 is in the sixth sliding section 523 and the first slide bar 321 is in the third sliding section 513, the sixth sliding section 523 and the third sliding section 513 are arranged side by side in the second direction and are interconnected. When in use, the first slide bar 321 can be set at the end of the upper cover 320, and the second slide bar 331 can be set at the end of the lower cover 330, so that the distance from the conveyor belt 200 along the third direction is as large as possible, so that the upper cover 320 and the lower cover 330 are easier to rotate.

[0060] And the size of the first slide bar 321 in the second direction is smaller than the size of the second slide bar 331 in the second direction, that is, the first slide bar 321 is short and the second slide bar 331 is long, so that the depth of the first slide rail 510 is smaller than the depth of the second slide rail 520, that is, the first slide rail 510 is shallow and the second slide rail 520 is deep, and the diameter of the first slide bar 321 is larger, that is, the first slide bar 321 is thick and the second slide bar 331 is thin, so that when the movement of the hopper 300 in the shell 100 is in the second stroke, the first slide bar 321 can slide in the third sliding section 513 and the second slide bar 331 can slide in the sixth sliding section 523.

[0061] And when the second sliding rod 331 slides from the sixth sliding section 523 to the fourth sliding section 521, the first sliding rail 510 and the second sliding rail 520 will separate and no longer overlap, the upper cover 320 is still in the third sliding section 513, and the lower cover 330 will gradually open. At this time, the upper cover 320 is still in a closed state. Due to the different structures of the first sliding rod 321 and the second sliding rod 331, the first sliding rail 510 and the second sliding rail 520, the second sliding rod 331 will automatically enter the fourth sliding section 521 of its corresponding second sliding rail 520 and will not continue to slide with the third sliding section 513 of the first sliding rail 510.

[0062] Similarly, when the first sliding rod 321 slides from the third sliding section 513 to the first sliding section 511, the first sliding rail 510 and the second sliding rail 520 will separate and no longer overlap, the lower cover 330 will still be in the sixth sliding section 523, and the upper cover 320 will gradually open. At this time, the lower cover 330 is still in a closed state. At this time, the first sliding rod 321 will also automatically enter the first sliding section 511 of its corresponding first sliding rail 510 under the restriction of its own structure and the first sliding rail 510, and will not continue to slide with the sixth sliding section 523 of the second sliding rail 520.

[0063] Alternatively, in another possible embodiment, the first slide rail 510 and the second slide rail 520 are arranged side by side in the third direction.

[0064] That is, the first slide bar 321 will slide along the first slide rail 510, and the second slide bar 331 will slide along the second slide rail 520. There is no overlapping area between the first slide rail 510 and the second slide rail 520, and the distance between the first slide rail 510 and the second slide rail 520 in the third direction is sufficient to open or close the first slide bar 321 and the second slide bar 331.

[0065] Alternatively, in a further embodiment, the tenth end of the fifth sliding segment 522 and the second first end of the discharge port 120 are located on the same horizontal line in the third direction.

[0066] By making the tenth end of the fifth sliding section 522 and the second head end of the discharge port 120 be on the same horizontal line in the third direction, when the second sliding rod 331 on the lower cover 330 slides to the tenth end of the fifth sliding section 522, the lower cover 330 will be completely closed and will no longer discharge materials. By changing the setting positions of the fourth sliding section 521, the fifth sliding section 522 and the sixth sliding section 523, the opening or closing node of the lower cover 330 can be controlled, so that when the lower cover 330 passes the second head end of the discharge port 120, it will no longer discharge materials, thereby further preventing materials from falling into the outer shell 100.

[0067] In combination with the above embodiment, the specific working process is as follows: when in use, the conveyor belt 200 is driven to rotate around the second direction and drive multiple hoppers 300 to rotate synchronously, and then the material is put into the housing 100 from the side of the feed port 110. The first end of the first sliding section 511 is used as the starting point for description. At this time, the first slide bar 321 gradually slides toward the second end along the first end of the first sliding section 511, and the upper cover 320 will gradually open. When the first slide bar 321 slides to the side of the second end of the first sliding section 511, the hopper 300 rotates to the downstream side of the feed port 110, so that when the material enters from the feed port 110, the material can enter the hopper 300. And the feeding direction of the material entering the hopper 300 from the feed port 110 is the same as the movement direction of the hopper 300.

[0068] After the first slide bar 321 slides to the second end of the first slide section 511, the first slide bar 321 will come to the third end of the second slide section 512 (the second end and the third end can be regarded as two overlapping end points), and then the first slide bar 321 will gradually slide along the third end of the second slide section 512 to the fourth end, at which time the upper cover 320 will rotate relative to the housing 310 under the guidance of the second slide section 512, and gradually close to complete the material connection. In the above process, the second slide bar 331 of the lower cover 330 slides in the sixth slide section 523, so that the lower cover 330 remains closed. This is the first stroke of the movement of the hopper 300 in the housing 100.

[0069] After the first slide bar 321 slides to the fourth end of the second slide section 512, the first slide bar 321 will come to the fifth end of the third slide section 513 (the fourth end and the fifth end can be regarded as two overlapping end points), and then the first slide bar 321 will gradually slide along the fifth end of the third slide section 513 to the sixth end. During this process, the upper cover 320 remains in a closed state. The second slide bar 331 of the lower cover 330 slides in the sixth slide section 523, so that the lower cover 330 remains closed. At this time, it is the second stroke of the movement of the hopper 300 in the housing 100, and the upper and lower ends of the hopper 300 are closed. Prevent materials from spilling during transportation.

[0070] Until the second sliding rod 331 of the lower cover 330 slides to the twelfth end of the sixth sliding section 523, that is, the seventh end of the fourth sliding section 521 (the seventh end and the twelfth end can be regarded as two overlapping end points), then the second sliding rod 331 will gradually slide along the seventh end of the fourth sliding section 521 to the eighth end, and the lower cover 330 will rotate relative to the shell 310 under the guidance of the fourth sliding section 521, and gradually open. When the second sliding rod 331 slides to the eighth end of the fourth sliding section 521, the lower cover 330 is opened to the maximum. At this time, the hopper 300 rotates to the upstream side of the discharge port 120 to ensure that the material can be discharged from the hopper 300 to the discharge port 120, and try to avoid the material falling into the shell 100 to affect the normal transportation of the material.

[0071] When the second slide bar 331 slides to the eighth end of the fourth sliding section 521, the second slide bar 331 will come to the ninth end of the fifth sliding section 522 (the eighth end and the ninth end can be regarded as two overlapping end points), and then the second slide bar 331 will gradually slide along the ninth end of the fifth sliding section 522 to the tenth end, at which time the lower cover 330 will rotate relative to the shell 310 under the guidance of the fifth sliding section 522, and gradually close to complete the discharge. In the above process, the first slide bar 321 of the upper cover 320 slides in the third sliding section 513, so that the upper cover 320 remains closed. This is the third stroke of the movement of the hopper 300 in the shell 100. During the movement of the hopper 300, the upper and lower ends of the hopper 300 are switched between open and closed, so that the hopper 300 can realize feeding or discharging, and ensure the stable transportation.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
