Description

Technical Field

[0001] The invention relates to the technical field of elevators, in particular to a bucket elevator and an elevator system based on selected tailings sediment. Background Art

[0002] Bucket elevator is a fixed mechanical conveying equipment, mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials. It can be widely used in feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, port terminals, etc. of various sizes for lifting bulk materials.

[0003] At present, when a bucket elevator is in use, it is necessary to adjust the running speed of the material according to the actual material being transported and lifted. When the existing elevator is working, the bucket will scoop up the material from the storage below, lift it to the top with the conveyor belt or chain, bypass the top wheel and flip it downward, and finally pour the material into the receiving trough. When the transportation speed of the elevator changes, the scooping or filling time of the bucket will change. This makes the amount of material carried by the bucket different at different speeds: the faster the running speed, the less the bucket carries. Therefore, in this state, although the running speed is improved, the final material transfer efficiency will not change, and the purpose of speeding up material transportation cannot be achieved.

[0019] In the present invention, the material transfer is realized by setting a lifting component, utilizing the uniform speed movement of the lifting component and the barrier transportation of the baffle plate;

[0020] At the same time, by setting the amount adjustment component and utilizing the cooperation between the blocking member and the driving structure, the transportation speed of the lifting component can be adjusted while changing the conduction amount of the deflection cylinder loading port, so that no matter what the lifting speed of the lifting component is, the loading port has a material discharge speed that is adapted to the running speed, so that no matter what the speed state is, the amount of material falling between the two sets of baffles on the lifting component is always the same.

[0034] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0035] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0036] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0037] See also Figure 1-Figure 10 In an embodiment of the present invention, a tailings silt bucket elevator based on selection includes:

[0038] A deflection cylinder 3 mounted on the bottom support member 1, a sleeve cylinder 2 is slidably arranged on the deflection cylinder 3, and an external box 8 is arranged on the deflection cylinder 3, and an adjustment component is arranged on the external box 8, and the adjustment component includes a blocking member and a driving structure, and when the driving structure is actuated, the blocking member can be driven to move relative to the deflection cylinder 3, so as to adjust the conductance of the feed port 301 on the deflection cylinder 3;

[0039] Preferably, see Figure 1 , Figure 5 , Fig. 9 The above-mentioned deflection cylinder 3 is rotatably connected to the support block 101 fixedly arranged on the bottom supporting member 1, and the above-mentioned sleeve cylinder 2 is provided with a discharge port 201 on the side facing the bottom supporting member 1. In detail, the left and right sides of the above-mentioned sleeve cylinder 2 are provided with slide grooves 202, and a slider 7 is slidably arranged in the slide groove 202. The bottom supporting member 1 is also fixedly installed with a cylinder 6, and the cylinder 6 is symmetrically arranged in two groups along the width direction of the bottom supporting member 1. The two groups of the cylinders 6 are controlled by the same driving power supply, and the telescopic ends of the two groups of the cylinders 6 are rotatably connected with the slider 7. By driving the cylinder 6, the sleeve cylinder 2 and the deflection cylinder 3 can be driven to deflect relative to the support block 101, thereby changing the discharge height of the discharge port 201 to be suitable for discharge operations at different heights.

[0040] The blocking member comprises a blocking plate 16 slidably disposed in the deflection cylinder 3, and the blocking plate 16 is provided with through grooves 1601 with decreasing areas at equal intervals;

[0041] Preferably, see Figure 8 , Fig. 9 The through grooves 1601 are arranged in three groups equidistantly along the length direction of the blocking plate 16. The areas of the three groups of through grooves 1601 gradually decrease along the direction of the deflection cylinder 3 toward the sleeve cylinder 2. By utilizing the cooperation between the through grooves 1601 and the loading port 301, the conduction amount of the loading port 301 per unit time can be changed. Combined with the speed change of the lifting component, the lifting component can freely change the material transfer speed.

[0042] The driving structure includes a guide plate 15 slidably disposed in the external box 8 and fixedly connected to the blocking plate 16, the guide plate 15 is provided with an embedded groove body, the embedded groove body includes moving grooves 2901 equidistantly provided on the guide plate 15, each group of the moving grooves 2901 is provided with a positioning groove 2902, and two adjacent groups of the moving grooves 2901 are connected by an inclined groove 2903;

[0043] Preferably, see Figure 8 The above-mentioned moving slots 2901 are arranged in three groups with equal spacing, such as Figure 8 As shown, the ends of the movable grooves 2901 at both ends are provided with positioning grooves 2902, the length of the movable groove 2901 at the middle position is twice the length of the movable grooves 2901 at the beginning or the end, and a positioning groove 2902 is opened at the middle end of the movable groove 2901 at the middle position.

[0044] It also includes a mounting member 1501 fixedly disposed on the guide plate 15, wherein two groups of the mounting members 1501 are symmetrically disposed along the width direction of the guide plate 15, and the two groups of the mounting members 1501 are connected to the deflection cylinder 3 through a first spring 30;

[0045] For details, please refer to Figure 1 , Figure 5 , Fig. 9 The mounting member 1501 is slidably arranged in the leading grooves 802 opened on the left and right sides of the external accessory box 8, and a transverse groove 801 is opened on the external accessory box 8, and a sliding member 9 is arranged in the transverse groove 801, and one end of the sliding member 9 immersed in the external accessory box 8 is arranged in the embedded groove body;

[0046] It is particularly important to note that the first spring 30 is always in a compressed state. The first spring 30 in the compressed state pushes the guide plate 15 to move away from the feeding port 301. In the initial state, the through slot 1601 with the largest area coincides with the feeding port 301, and the sliding member 9 is located at the end of the travel of the transverse slot 801 and is located in the positioning slot 2902 away from the blocking plate 16 (combined with the Figure 8 ), due to the pushing effect of the first spring 30 on the guide plate 15, the sliding member 9 can keep the position of the guide plate 15 fixed. At this time, the operating speed of the lifting assembly is the largest, which is suitable for lifting lighter raw materials (dry tailings silt) or finished products. However, when lifting rougher raw materials or semi-finished products, in order to ensure lifting safety and accurate positioning, the speed of the lifting assembly needs to be reduced;

[0047] In the present invention, combined with Figure 8 If the lifting speed needs to be reduced, the hand-held sliding member 9 slides along the transverse groove 801. During the sliding process, the contact and extrusion between the sliding member 9 and the groove wall of the positioning groove 2902 can force the sliding member 9 to separate from the positioning groove 2902, and then the sliding member 9 is combined with the moving groove 2901 and slides along the moving groove 2901 until the sliding member 9 is combined with the inclined groove 2903, and then the sliding member 9 is pushed. At this time, the contact and extrusion between the sliding member 9 and the groove wall of the inclined groove 2903 can force the guide plate 15 to drive the blocking plate 16 to approach the bottom supporting member 1 along the length direction of the deflection cylinder 3. When the sliding member 9 is combined with the next group of moving grooves 2901, the upper and lower groups of through grooves 1601 with smaller areas of the blocking plate 16 are combined with the loading port 301. At this time, the unloading port area of ​​the loading port 301 is reduced, and the material entering the deflection cylinder 3 through the loading port 301 per unit time will be relatively reduced;

[0048] Then, the sliding member 9 is continuously pushed, and the sliding member 9 slides along the moving groove 2901 until the sliding member 9 is about to engage with the positioning groove 2902 on the moving groove 2901, and the first spring 30 releases its elastic potential energy, which can push the guide plate 15 to continue to move a short distance in the direction of the bottom supporting member 1, and engage the sliding member 9 in the positioning groove 2902, so that the position of the blocking plate 16 is fixed, thereby maintaining the unloading opening area of ​​the loading port 301, so that the loading port 301 can feed the lifting assembly in a stable input manner; when it is necessary to adjust the unloading opening area of ​​the loading port 301 again, the sliding member 9 is continuously pushed in the same direction, and after the sliding member 9 is engaged with the next set of positioning grooves 2902, the opening area of ​​the loading port 301 can be further reduced with the cooperation of the blocking plate 16;

[0049] In combination with the above, the opening area of ​​the loading port 301 is combined with the running speed of the lifting component, so that no matter what the running lifting speed of the lifting component is, the loading port 301 has a unloading speed that matches the running speed. The two cooperate with each other and can freely adjust the material transfer efficiency of the elevator, thereby meeting the actual material transfer needs during transfer.

[0050] Furthermore, it also includes a lifting assembly arranged in the deflection cylinder 3 and the sleeve cylinder 2, and the lifting assembly can transport the material entering the upper material port 301 to the lower material port 201 of the sleeve cylinder 2, and when the blocking member is actuated, it can drive the speed regulating structure arranged on the deflection cylinder 3 to cooperate, so as to adjust the speed of the lifting assembly;

[0051] The speed regulating structure includes a rack plate 32 fixedly connected to the mounting member 1501, the rack plate 32 is meshed with a driving wheel 31 rotatably mounted on the external accessory box 8, and the driving wheel 31 is coaxially fixed with the gear switch;

[0052] Preferably, see Figure 1 , Figure 5 , Fig. 9 , Fig.10 The gear switch is connected to the driving motor controlling the lifting assembly in communication. In combination with the above, in the initial state, when the material discharge opening area of ​​the loading port 301 is maintained at the maximum state, the gear switch controls the driving motor to be in the maximum speed state, and the sliding member 9 cooperates with the engaging groove body to drive the blocking plate 16 to slide relative to the loading port 301 and force the material discharge opening area of ​​the loading port 301 to decrease. In the process, the rack plate 32 fixed to the blocking plate 16 can drive the driving wheel 31 to rotate clockwise (combined with Fig. 9 ), at this time, the gear switch is actuated to adjust the speed of the drive motor, causing the speed of the drive motor to decrease;

[0053] With the cooperation of the quantity adjustment component and the speed adjustment structure, the elevator can adjust the efficiency of material transfer according to the needs of actual operations, thereby improving the overall practical performance of the elevator.

[0054] For further information, see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 In actual use, the hoist can lift the material in the loading port 301 to the top through the lifting assembly, bypass the top wheel and flip downward, and then pour the material into the receiving tank (not shown in the figure) through the unloading port 201. However, in the actual transportation process, the slot heights of the receiving tank are not the same. In order to reduce the spillage of materials during unloading, the unloading port 201 is usually close to the slot of the receiving tank. In the present invention, by driving the cylinder 6 to move, the sleeve tube 2 and the deflection tube 3 can be driven to deflect relative to the support block 101, thereby changing the distance between the unloading port 201 and the ground or the receiving tank. At present, the distance between the unloading port 201 and the receiving tank of the hoist is mostly driven by the cylinder 6. However, the transportation length of the existing hoist is constant. Therefore, when the distance between the unloading port and the receiving tank is changed, the horizontal distance between the loading port 301 and the receiving tank will also change relatively. Therefore, when adjusting the distance between the loading port 301 and the receiving tank, the fixed position of the hoist also needs to be changed;

[0055] In the present invention, a height adjustment mechanism is arranged between the deflection cylinder 3 and the sleeve cylinder 2, and the height adjustment mechanism includes a telescopic component and a linkage component. By utilizing the cooperation between the telescopic component and the linkage component, the elevator can have two ways of adjusting the discharge port 201: one is to change the height of the discharge port 201 when the transportation length remains unchanged (to cope with the situation where the fixed position of the elevator remains unchanged and the receiving slot can be horizontally displaced); the other is to change the height of the discharge port 201 and the transportation length of the lifting component at the same time when the fixed position of the elevator and the position of the receiving slot remain unchanged.

[0056] In detail, the telescopic assembly includes a screw rod 4 rotatably mounted on the deflection cylinder 3, the screw rod 4 is provided with a threaded sleeve 5 threadedly connected thereto, and the threaded sleeve 5 is fixedly connected to a mounting block 203 fixedly arranged on the sleeve cylinder 2;

[0057] The linkage assembly includes a support block 101 fixedly arranged on the bottom supporting member 1, a fixed sleeve 28 is arranged on the support block 101, the fixed sleeve 28 is coaxial with the deflection center of the deflection cylinder 3, and a third spring 27 is slidably arranged in the fixed sleeve 28, one end of the third spring 27 abuts against the bottom of the fixed sleeve 28, and the other end abuts against the linkage member arranged in the fixed sleeve 28;

[0058] The linkage member includes a rotating rod 26 disposed in the fixed sleeve 28, a composite groove is provided on the outer wall of the rotating rod 26, a protrusion fixedly connected to the fixed sleeve 28 is slidably provided in the composite groove, and an arc-shaped toothed plate 21 is fixedly provided on the rotating rod 26, and the arc-shaped toothed plate 21 is meshed with a slave gear 22 rotatably mounted on the deflection cylinder 3; Figure 1 , Figure 5 , Figure 6 A driving wheel 23 is coaxially fixed on the above-mentioned driven gear 22, and the driving wheel 23 is connected to a driven wheel 24 rotatably mounted on the deflection cylinder 3 through a linkage belt. In particular, the radius of the driving wheel 23 is multiple times the radius of the driven wheel 24, and the driven wheel 24 is connected to the screw rod 4 through a bevel gear set 25. In detail, the bevel gear set 25 includes a first bevel gear and a second bevel gear, the first bevel gear is coaxially fixed to the driven wheel 24, and the second bevel gear is coaxially fixed to the screw rod 4;

[0059] For details, please refer to Figure 7 The composite groove includes a vertical groove 2601, an arc groove 2602 and a locking groove 2603 formed on the outer wall of the rotating rod 26. In the initial state, the third spring 27 is in a compressed state. The third spring 27 in the compressed state pushes the rotating rod 26 to move toward the outside of the fixed sleeve 28. At this time, the protrusion formed on the inner wall of the fixed sleeve 28 is just stuck at the end of the vertical groove 2601 away from the arc groove 2602. At this time, the arc-shaped tooth plate 21 is in a meshing state with the slave gear 22 (such as Figure 1 In the initial state, the threaded sleeve 5 is close to the bevel gear set 25, and when the cylinder 6 is driven to push the sleeve 2 to rotate counterclockwise (combined with Figure 1 ), the slave gear 22 cooperates with the arc-shaped toothed plate 21 and can rotate counterclockwise, and then under the cooperation of the driving wheel 23, the driven wheel 24 and the bevel gear set 25, the slave gear 22 can drive the screw rod 4 to rotate multiple circles in the same direction, thereby forcing the threaded sleeve 5 to drive the mounting block 203 and the sleeve tube 2 to gradually move away from the support block 101. It should be supplemented that during the entire adjustment process, the projection position of the discharge port 201 on the bottom supporting member 1 remains unchanged. Therefore, after the position of the elevator and the receiving slot is fixed, the discharge port 201 can be controlled to be close to the slot of the receiving slot by the above method, thereby reducing the phenomenon of material scattering during the discharge process;

[0060] In detail, the sleeve tube 2 is sleeved on the plug-in tube 302 fixedly arranged on the deflection tube 3. With the cooperation of the plug-in tube 302, the sleeve tube 2 will never be separated from the deflection tube 3. During the sliding process of the sleeve tube 2 relative to the deflection tube 3, the transportation length of the lifting assembly will also change accordingly, which is described in detail as follows.

[0061] The lifting assembly includes a first pulley 10, a second pulley 11, a positioning rod 17 and a tensioning structure, the tensioning structure includes a guide rod 18 fixedly arranged in the deflection cylinder 3, and two groups of guide rods 18 are symmetrically arranged along the width direction of the deflection cylinder 3. Second springs 19 are slidably arranged on the two groups of guide rods 18, one end of the second spring 19 abuts against the end of the guide rod 18, and the other end abuts against a moving block 20 slidably arranged on the guide rod 18, and a moving wheel 13 is rotatably installed between the two groups of moving blocks 20;

[0062] The lifting assembly further includes a conveyor belt 12 connected to the first pulley 10, the second pulley 11, the positioning rod 17 and the moving wheel 13, and baffle plates 1201 are fixedly arranged on the conveyor belt 12 at equal intervals, and the baffle plates 1201 are used to hold materials;

[0063] Preferably, see Figure 2 , Figure 3 , Figure 4 The positioning rod 17 is placed in the through groove 1202 opened on the conveyor belt 12. With the cooperation of the first pulley 10, the second pulley 11, the positioning rod 17 and the moving wheel 13, the conveyor belt 12 is as follows. Figure 2 , Figure 3 The state shown is placed in the deflection cylinder 3 and the sleeve cylinder 2, and the second spring 19 is always in a compressed state. The second spring 19 in the compressed state pushes the moving wheel 13 away from the plane formed by the axis of the first pulley 10 and the second pulley 11, so that the conveyor belt 12 is in a taut state, so that the conveying operation can be carried out;

[0064] In particular, the second pulley 11 is connected to a driving rod 14 rotatably mounted on the deflection cylinder 3 through a linkage belt, and the driving rod 14 is fixedly connected to the output shaft of the driving motor. By starting the driving motor, the conveyor belt 12 can be driven to rotate clockwise, thereby transferring materials;

[0065] In combination with the above, when the sleeve tube 2 slides relative to the deflection tube 3, the first pulley 10 will follow the sleeve tube 2 to move relative to the deflection tube 3. At the same time, since the length of the conveyor belt 12 is fixed, when the sleeve tube 2 gradually moves away from the deflection tube 3, the extrusion of the conveyor belt 12 on the moving wheel 13 can force the moving block 20 to further squeeze the second spring 19. At this time, due to the reverse effect of the second spring 19 on the moving wheel 13, the conveyor belt 12 is always in a taut state, and the transport parallel surface close to the loading port 301 will increase, so that the conveyor belt 12 can normally transport the materials entering the deflection tube 3 through the loading port 301 to the unloading port 201 for discharge;

[0066] Another method of adjusting the height of the discharge port 201 of the present invention is based on the premise of not changing the transport length, and can cope with the situation where the height of the receiving slot remains unchanged but can be moved horizontally. At this time, the hand-held arc-shaped toothed plate 21 is pressed toward the fixed sleeve 28, and the third spring 27 is further squeezed. During this process, the protrusion on the inner wall of the fixed sleeve 28 slides in the vertical groove 2601 until the protrusion contacts the arc groove 2602, and the arc-shaped toothed plate 21 is staggered from the gear 22 and disengaged, and then the arc-shaped toothed plate 21 is rotated counterclockwise (combined with the arc-shaped toothed plate 21). Figure 7 ), when the protrusion moves to contact the locking groove 2603, the arc-shaped toothed plate 21 is released, and then the third spring 27 releases its elastic potential energy, which can push the arc-shaped toothed plate 21 to move an end distance toward the outside of the fixed sleeve 28, and then the protrusion is combined with the locking groove 2603 to lock the position of the arc-shaped toothed plate 21. At this time, the driving cylinder 6 is actuated, and the slave gear 22 cannot be combined with the arc-shaped toothed plate 21. The sleeve tube 2 can only change the distance between the discharge port 201 and the receiving groove by deflection following the deflection tube 3; when it is necessary to change the adjustment mode, the arc-shaped toothed plate 21 is pressed again, and then reversed. After it cannot rotate, the arc-shaped toothed plate 21 is released, and the third spring 27 releases its elastic potential energy, which can make the protrusion contact with the formed end of the vertical groove 2601 again, so that the arc-shaped toothed plate 21 is restored to the meshing state with the slave gear 22;

[0067] In summary, in the present invention, by changing the meshing state of the arc-shaped tooth plate 21 and the slave gear 22, there are two ways to change the height of the discharge port 201. The two sets of height adjustment methods can meet the control of the distance between the discharge port 201 and the receiving slot under different restriction conditions, thereby improving the overall practicality and flexibility of the elevator.

[0068] A tailings sediment bucket elevator system based on concentration is also proposed, which adopts the tailings sediment bucket elevator based on concentration as described above.
