Description

Technical Field

[0001] The invention relates to the technical field of material lifting, in particular to a chain plate type bucket elevator. Background Art

[0002] Bucket elevator is a conveying equipment used to continuously convey powdered, granular and small block materials in a vertical or nearly vertical direction. Its working principle is to scoop up the materials from the lower storage through a series of hoppers fixed on the traction chain or belt, lift them to the top with the conveyor belt or chain, bypass the top wheel and then flip downward to pour the materials into the receiving trough.

[0003] There are many types of bucket elevators available, which are mainly divided into three types: belt type, chain type and chain plate type according to the different traction devices. Among them, chain plate bucket elevators are widely used in building materials, chemical industry, mining, electric power and other industries because of their good sealing, convenient operation and maintenance and small footprint.

[0004] In the related art, for example, Chinese patent CN207209184U discloses a bucket elevator with a function of automatically raising the material height. When the bucket elevator with the function of automatically raising the material height is conveying rice, the rice is lifted up by the hopper so that the rice decreases in height, and the distance between the rice and the ultrasonic distance sensor increases, thereby exceeding the set value of the comparator. At this time, the power device is started to move the storage plate upward, thereby increasing the height of the rice, until the distance between the rice and the ultrasonic distance sensor is less than the set value of the comparator, the power device stops the storage plate from continuing to move, thereby keeping the height difference between the hopper and the rice unchanged, so that the hopper can carry more rice each time, thereby improving the conveying efficiency of the rice, and when the rice is conveyed, the vibrator is turned on to make the rice material at a higher place fall down, so that the rice material is more evenly distributed everywhere, which is convenient for being scooped up by the hopper.

[0005] Although the above-mentioned bucket elevator with the function of automatically raising the material height can ensure to a certain extent that the bucket can hold a sufficient amount of material every time it moves to the bottom, it is found in actual use that when the bucket moves to the top, most of the material inside it is mainly thrown out by centrifugal force, and a small part of the material cannot be thrown out due to its deep position, and can only fall back into the bucket elevator as the bucket flips, affecting the material conveying efficiency.

There are two chains 11, which are spaced apart in the horizontal direction and are simultaneously transmission-sleeved on the outside of the driving sprocket 12, the driven sprocket 13 and the reversing sprocket 14.

[0043] There are two driving sprockets 12, which are coaxial and spaced apart in the horizontal direction and are both inserted at the top of the casing 1. To facilitate the installation of the two driving sprockets 12, the chain plate bucket elevator is configured to further include a first rotating shaft, which is horizontally arranged at the top of the casing 1 and vertically penetrates the front and rear side walls of the casing 1 during installation. The two driving sprockets 12 are respectively fixedly sleeved at both ends of the first rotating shaft; there are two driven sprockets 13, which are coaxial and spaced apart in the horizontal direction. The two driven sprockets 13 are arranged at intervals and are inserted at the bottom of the casing 1; in order to facilitate the installation of the two driven sprockets 13, the chain plate bucket elevator is configured to also include a second rotating shaft, the second rotating shaft is horizontally arranged at the bottom of the casing 1, and vertically penetrates the front and rear side walls of the casing 1 when installed, the axis of the second rotating shaft and the axis of the first rotating shaft are located in the same vertical plane, and the two driven sprockets 13 are fixedly sleeved on both ends of the second rotating shaft respectively; the chain 11 between the driven sprocket 13 and the driving sprocket 12 is vertically arranged, and is a vertical lifting section.

[0044] There are two reversing sprockets 14, which are coaxial and inserted in the middle of the casing 1 and are located on the right side of the driving sprocket 12. To facilitate the installation of the two reversing sprockets 14, the chain plate bucket elevator is configured to also include a third rotating shaft, which is horizontally arranged in the middle of the casing 1 and vertically penetrates the front and rear side walls of the casing 1 when installed.

[0045] like Fig.10 As shown, the hopper 2 is configured as a box structure with an open top, the cross-sectional shape of the hopper 2 is configured as a rectangle, and the vertical cross-sectional shape is configured as a U-shape; in order to facilitate connecting the hopper 2 to the chain 11, the chain plate bucket elevator is configured to further include a plurality of pairs of connecting blocks 21, a pair of connecting blocks 21 is configured to correspond to one hopper 2 and two chains 11 at the same time, and the two connecting blocks 21 of the same pair are symmetrically arranged on the left side wall of the hopper 2; the connecting block 21 is configured as a U-shaped structure, and is arranged on the left side wall of the hopper 2 with the opening facing right during installation, as shown in FIG. Figure 3 As shown, the other end of the connecting block 21 opposite to the opening is fixedly sleeved on the chain 11 .

[0046] When in use, the driving sprocket 12 is first driven to rotate in the clockwise direction through the driving mechanism 5; during the process of the driving sprocket 12 rotating in the clockwise direction, the driving sprocket 12 synchronously drives the driven sprocket 13 and the reversing sprocket 14 to rotate in the clockwise direction through the chain 11, so that the chain 11 forms a closed triangular conveying loop inside the casing 1, and then the hopper 2 can move along the triangular conveying loop.

[0047] During the movement of the hopper 2, materials are simultaneously fed into the casing 1 through the feed port 101. When the hopper 2 moves in the vertical lifting section, the hopper 2 first receives the materials fed from the feed port 101, and then closes the opening under the action of the closing component to avoid spilling of materials during the lifting process.

[0048] When the hopper 2 switches from the vertical lifting section to the inclined material pouring section, the hopper 2 turns over under the traction of the chain 11, so that the opening of the hopper 2 is set to the lower right, which is convenient for discharging.

[0049] When the hopper 2 moves in the inclined material discharge section, the opening of the hopper 2 is opened under the action of the closing component, and the material inside the hopper 2 can be completely poured out under the action of gravity and discharged from the discharge port 102, which prevents the material from falling back into the casing 1 and helps to improve the material conveying efficiency.

[0050] When the hopper 2 switches from the inclined material discharge section to the inclined recovery section, the opening of the hopper 2 is set to the lower left under the traction of the chain 11.

[0051] When the hopper 2 switches from the inclined recovery section to the vertical lifting section, the hopper 2 flips under the traction of the chain 11, so that the opening of the hopper 2 is set upward, which is convenient for receiving materials; and because the hopper 2 filled with materials is distributed in the vertical lifting section and the inclined material pouring section at the same time, the energy required to lift the hopper 2 in the vertical lifting section is partially converted by the gravitational potential energy of the hopper 2 in the inclined material pouring section, which is beneficial to reduce the load of the driving mechanism 5 and reduce the use cost.

[0052] In some embodiments, the closing assembly is configured to include a cover plate 31 and a switching portion 32, one end of the cover plate 31 is elastically hinged to the top of the inner side of the hopper 2, and the other end is suspended.

[0053] Specifically in this embodiment, Figure 3 As shown, the cover plate 31 is configured as a rectangular plate-shaped structure, and is configured to include a mounting frame 311 and a sealing plate 312, as shown in FIG. Fig.10As shown, the mounting frame 311 is configured as a rectangular frame structure, and when installed, the left long side is hinged to the left top of the hopper 2, and the right long side is suspended; the sealing plate 312 is configured as a rectangular plate-like structure, and when installed, the cover is arranged on the top of the mounting frame 311; in order to facilitate the hinge connection of the mounting frame 311 to the hopper 2, a rotating shaft 201 is arranged in parallel at the left top of the hopper 2, and the rotating shaft 201 is configured as an "I"-shaped rotating body structure, and is configured to include a "T"-shaped fixed part and a ring-shaped rotating part, wherein the fixed part is fixedly set on the hopper 2 during installation, and the rotating part can be relatively rotatably sleeved on the front end of the fixed part during installation, and the left end of the front short side of the mounting frame 311 is fixedly sleeved on the rotating part during installation, and the left end of the rear short side can be relatively rotatably sleeved on the rear end of the fixed part.

The second guide part 17 has a second inclined surface 171, and the extension direction of the second inclined surface 171 is the same as the inclination direction of the inclined return section, and the second inclined surface 171 cooperates with the guide of the clamping plate 322; the third guide part 18 has a third inclined surface 181, and the extension direction of the third inclined surface 181 is the same as the inclination direction of the inclined material pouring section, and the third inclined surface 181 cooperates with the guide of the clamping plate 322.

[0056] Specifically in this embodiment, Fig.10As shown, the card strip 321 is set as a "7"-shaped strip structure, and is parallel and fixedly set on the right top of the hopper 2 during installation, and the bent section of the card strip 321 is set toward the rotating shaft 201; the card plate 322 is set as a rectangular plate structure, and is inserted into the mounting frame 311 during installation; in order to facilitate the support of the card plate 322, two guide columns 3221 are vertically and symmetrically arranged on the front and rear side walls of the card plate 322 and the left end, and the guide columns 3221 are set as a T-shaped structure, and the large end is set outward, and the two short side walls of the mounting frame 311 are provided with sliding holes 3111 in the middle, and the card plate 32 During installation, the guide column 3221 is arranged to be slidably inserted into the slide hole 3111; in order to facilitate the elastic sliding of the clamping plate 322, a plurality of compression springs 34 are vertically and fixedly arranged on the right side wall of the left long side of the mounting frame 311, and the plurality of compression springs 34 are arranged at intervals along the length direction of the mounting frame 311, and the other ends of the compression springs 34 are vertically and fixed / abutted against the left side wall of the clamping plate 322. Under the action of the compression springs 34, the clamping plate 322 has a tendency to extend out of the cover plate 31; in order to facilitate the smoothness of the clamping plate 322 and the clamping strip 321 when clamping, the right side wall of the clamping plate 322 is arranged as an inclined surface, and the inclined surface is extended in the lower left direction.

[0057] like Figure 2 and Figure 3 As shown, the first guide portion 16 is disposed on the rear inner wall surface of the housing 1. Figure 7 As shown, the first guide portion 16 is configured as a plate-like structure in the shape of a right-angled trapezoid, and the short base and the long base of the first guide portion 16 are both extended in the vertical direction, and the short base is located on the left side of the long base, and the right-angled waist is horizontally arranged and located above the oblique waist; the plane where the oblique waist is located is set as the first inclined surface 161.

[0058] Before receiving the materials, the cover plate 31 is arranged vertically.

[0059] When the hopper 2 moves to the first guide portion 16, the guide post 3221 first abuts against the first inclined surface 161. As the chain 11 moves, the hopper 2 moves upward relative to the first guide portion 16. Under the push of the first inclined surface 161, the guide post 3221 moves downward along the slide hole 3111. The guide post 3221 simultaneously drives the clamping plate 322 to retract into the inside of the cover plate 31, and the compression spring 34 is compressed. When the clamping plate 322 is completely retracted into the inside of the cover plate 31, the guide post 3221 continues to push the first inclined surface 161 and drives the cover plate 31 to rotate counterclockwise around the rotating shaft 201 until the cover plate 31 is horizontally arranged. When the guide post 3221 disengages from the first inclined surface 161, the compression spring 34 is released, synchronously driving the clamping plate 322 to extend from the inside of the cover plate 31 and be clamped on the clamping strip 321, thereby sealing the hopper 2.

[0060] like Figure 6 and Fig. 9As shown, the second guide portion 17 and the third guide portion 18 are both arranged on the rear inner wall surface of the casing 1, and the second guide portion 17 is located at the upper right of the third guide portion 18, the second guide portion 17 is arranged as a plate-like structure in the shape of a right-angled trapezoid, and the short bottom side and the long bottom side of the second guide portion 17 are both extended in the vertical direction, and the short bottom side is located on the left side of the long bottom side, the right-angled waist is arranged horizontally and is located below the oblique waist, and the plane where the oblique waist is located is arranged as the second inclined surface 171; the third guide portion 18 is arranged as a plate-like structure in the shape of a pentagon, and is obtained by cutting off a corner of a rectangle, the oblique side of the third guide portion 18 is located at the upper right, and extends obliquely in the lower right direction.

[0061] During use, when the hopper 2 moves to the second guide portion 17, the guide column 3221 first abuts against the second inclined surface 171. As the chain 11 moves, the hopper 2 moves downward relative to the second guide portion 17. Under the push of the second inclined surface 171, the guide column 3221 moves along the slide hole 3111 in a direction away from the clamping strip 321. The guide column 3221 simultaneously drives the clamping plate 322 to retract into the cover plate 31, while disengaging the clamping block and the clamping strip 321. When the clamping plate 322 is completely retracted into the cover plate 31, the cover plate 31 has a tendency to rotate clockwise around the rotation axis 201 under the action of the gravity of the material to open the opening of the hopper 2; when the guide column 3221 and the second inclined surface 171 are disengaged, the cover plate 31 rotates clockwise around the rotation axis 201 under the action of the gravity of the material until it abuts against the third inclined surface 181, and the clamping plate 322 then extends out from the inside of the cover plate 31 under the action of the compression spring 34.

[0062] In a further embodiment, the height of the lifted material of the same elevator is often not adjustable and cannot adapt to complex work requirements. To solve this problem, the chain-type bucket elevator is configured to also include an adjustment mechanism 4, and the adjustment mechanism 4 is configured to be able to adjust the direction of the cover plate 31 when opening the opening of the hopper 2 to change the pouring direction of the material.

[0063] When in use, the direction of the cover plate 31 when opening the hopper 2 can be adjusted through the adjustment mechanism 4. While changing the pouring direction of the material, the direction of the material discharged from the discharge port 102 can be changed, thereby adapting to different material lifting height requirements and helping to improve versatility.

[0064] In a further embodiment, the adjustment mechanism 4 is configured to include a vertical adjustment component 41 and a horizontal adjustment component 42, the vertical adjustment component 41 is configured to be able to adjust the position of the reversing sprocket 14 in the vertical direction; the horizontal adjustment component 42 is configured to be able to adjust the position of the reversing sprocket 14 in the horizontal direction.

[0065] Specifically in this embodiment, Figure 6As shown, when the reversing sprocket 14 moves to the right, the angle between the vertical lifting section and the inclined material dumping section will increase, so that the rotation angle of the cover plate 31 when it is opened becomes larger, thereby being able to adapt to the discharge requirements of a lower height; similarly, when the reversing sprocket 14 moves to the left, the angle between the vertical lifting section and the inclined material dumping section will decrease, so that the rotation angle of the cover plate 31 when it is opened becomes smaller, thereby being able to adapt to the discharge requirements of a higher height.

[0066] When the reversing sprocket 14 moves upward, the angle between the vertical lifting section and the inclined material dumping section will increase, so that the rotation angle of the cover plate 31 when it is opened will become larger, thereby being able to adapt to the discharge requirements at a lower height; similarly, when the reversing sprocket 14 moves downward, the angle between the vertical lifting section and the inclined material dumping section will decrease, so that the rotation angle of the cover plate 31 when it is opened will become smaller, thereby being able to adapt to the discharge requirements at a higher height.

[0067] In a further embodiment, the vertical adjustment assembly 41 is configured to include a vertical first screw (not shown), one end of which is threadedly connected to the housing 1 and the other end is provided with a slider 411 , and the reversing sprocket 14 is disposed on the slider 411 .

[0068] Specifically in this embodiment, the first screw can be arranged outside the housing 1; Figure 2 As shown, one end of the slider 411 is slidably inserted into the housing 1, and the other end is set through the rear side wall of the housing 1; when installing, the first screw can be set so that the top end is fixedly connected to the bottom of the slider 411, and the bottom end is threadedly connected to the housing 1, and the second rotating shaft can be relatively rotatably set on the slider 411.

[0069] When in use, the first screw rod can be rotated to drive the second rotating shaft to move up and down in the vertical direction through the slider 411, and the second rotating shaft can synchronously drive the two reversing sprockets 14 to move up and down in the vertical direction.

[0070] In a further embodiment, the horizontal adjustment component 42 is configured to include a horizontally arranged second screw rod 421 , one end of the second screw rod 421 is threadedly connected to the slider 411 , and the other end is relatively rotatably arranged on the reversing sprocket 14 .

[0071] Specifically in this embodiment, Figure 2 As shown, the left end of the second screw rod 421 is vertically and threadedly connected to the right side wall of the slider 411, and the right end is relatively rotatably sleeved on the second rotating shaft.

[0072] When in use, the second screw rod 421 can be rotated to drive the second rotating shaft to move left and right in the horizontal direction, and the second rotating shaft can simultaneously drive the two reversing sprockets 14 to move left and right in the horizontal direction.

[0073] In other embodiments, the closing component is further provided with an elastic member, and the elastic member is connected to the hinge joint between the cover plate 31 and the hopper 2. Under the action of the elastic member, the cover plate 31 has a tendency to open the opening of the hopper 2.

[0074] Specifically in this embodiment, the elastic member is set as a torsion spring 33. As Figure 3 shown, when the torsion spring 33 is installed, it is sleeved on the rotating shaft 201, and the right end is fixedly arranged on the fixed part, and the left end is fixedly arranged on the rotating part. Under the action of the torsion spring 33, the cover plate 31 has a tendency to rotate clockwise around the rotating shaft 201.

[0075] In some other embodiments, the driving mechanism 5 is set to include a driving motor 51 and a speed reducer 52. The driving motor 51 and the speed reducer 52 are arranged outside the housing 1, and the input ends of the driving motor 51 and the speed reducer 52 are in transmission connection, and the output end of the speed reducer 52 is in transmission connection with the driving sprocket 12.

[0076] Specifically in this embodiment, as Figure 1 shown, for the convenience of installing the driving mechanism 5, an installation platform 15 is fixedly sleeved on the outer side wall of the top of the housing 1. The installation platform 15 is horizontally arranged, and the driving motor 51 and the speed reducer 52 are both fixedly connected to the top of the installation platform 15 by bolts during installation.

[0077] During use, the driving motor 51 is started, and the driving motor 51 drives the driving sprocket 12 to rotate by itself through the speed reducer 52.

[0078] In some other embodiments, to improve the stability of the hopper 2 during movement, the chain plate bucket elevator is further provided with a tensioning mechanism 6. The tensioning mechanism 6 is configured to be able to drive the driven sprocket 13 to move vertically to tension the chain 11.

[0079] Specifically in this embodiment, sliding bearing seats are sleeved on both ends of the second rotating shaft located outside the housing 1, and the sliding bearing seats can slide vertically; the tensioning mechanism 6 can be set to include a counterweight 61 and a sliding frame 62. The counterweight 61 is set as a strip structure and is horizontally penetrated through the front and rear side walls of the housing 1 during installation; the sliding frame 62 is set as a "C" - shaped structure with the opening facing downwards. The two suspended ends of the sliding frame 62 are respectively vertically and fixedly arranged on the tops of the two sliding bearing seats during installation, and the counterweight 61 is arranged on the top of the sliding frame 62 during installation; to enable the counterweight 61 and the sliding frame 62 to slide vertically, as Figure 1 shown, vertical slots 103 are penetrated through the front and rear side walls of the housing 1. The slots 103 extend vertically, and the counterweight 61 and the sliding block are simultaneously slidably inserted into the slots 103.

[0080] When in use, the second rotating shaft has a tendency to move downward in the vertical direction under the gravity of the counterweight 61 , and the second rotating shaft has a tendency to tighten the chain 11 through the driven sprocket 13 , so that the chain 11 can be tensioned.

[0081] It is understandable that the tensioning mechanism 6 can also be configured as any one of a spiral tensioning device, an automatic compensation tensioning device or a screw tensioning device in the prior art.

[0082] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0083] When in use, first rotate the first screw and the second screw 421 respectively according to the discharge height requirement, wherein the first screw drives the second rotating shaft to move in the vertical direction through the second screw 421, and the second rotating shaft simultaneously drives the two reversing sprockets 14 to move in the vertical direction; the second screw 421 drives the two reversing sprockets 14 to move in the horizontal direction through the second rotating shaft.

[0084] Then start the driving motor 51, which drives the driving sprocket 12 to rotate in the clockwise direction through the reducer 52; during the process of the driving sprocket 12 rotating in the clockwise direction, the driving sprocket 12 synchronously drives the driven sprocket 13 and the reversing sprocket 14 to rotate in the clockwise direction through the chain 11, so that the chain 11 forms a closed triangular conveying loop inside the casing 1, thereby enabling the hopper 2 to move along the triangular conveying loop.

[0085] During the movement of the hopper 2, materials are simultaneously fed into the casing 1 through the feed port 101. When the hopper 2 moves in the vertical lifting section, the hopper 2 first receives the materials fed from the feed port 101, and then moves to the first guide portion 16. When the hopper 2 moves to the first guide portion 16, the guide column 3221 first abuts against the first inclined surface 161. As the chain 11 moves, the hopper 2 moves upward relative to the first guide portion 16. Under the push of the first inclined surface 161, the guide column 3221 moves downward along the slide hole 3111. The guide column 3221 synchronously drives the card plate 322 to retract into the cover plate 31, and the compression spring 34 is compressed; when the card plate 322 is completely retracted into the cover plate 31, the guide column 3221 drives the cover plate 31 to rotate counterclockwise around the rotating shaft 201 until the cover plate 31 is horizontally set under the continued pushing of the first inclined surface 161, and the torsion spring 33 accumulates force; when the guide column 3221 is separated from the first inclined surface 161, the compression spring 34 is released, and synchronously drives the card plate 322 to extend from the inside of the cover plate 31 and be clamped on the clamping strip 321, thereby realizing the sealing of the hopper 2.

[0086] When the hopper 2 switches from the vertical lifting section to the inclined material discharge section, the hopper 2 is turned over under the traction of the chain 11, so that the opening is set to the lower right to facilitate material discharge.

[0087] When the hopper 2 moves in the inclined material discharge section, when the hopper 2 moves to the second guide portion 17, the guide column 3221 first abuts against the second inclined surface 171. As the chain 11 moves, the hopper 2 moves downward relative to the second guide portion 17. Under the push of the second inclined surface 171, the guide column 3221 moves along the slide hole 3111 in the direction away from the clamping strip 321. The guide column 3221 simultaneously drives the clamping plate 322 to retract into the inside of the cover plate 31, and at the same time, the compression spring 34 is compressed while the clamping block and the clamping strip 321 are disengaged. When the clamping plate 322 is fully retracted, the cover After the cover plate 31 is inside, under the action of the gravity of the material and the elastic action of the torsion spring 33, the cover plate 31 has a tendency to rotate clockwise around the rotating shaft 201 to open the opening of the hopper 2; when the guide column 3221 and the second inclined surface 171 are disengaged, under the action of the gravity of the material and the elastic action of the torsion spring 33, the cover plate 31 rotates clockwise around the rotating shaft 201 until it abuts against the third inclined surface 181. At this time, the material is poured out along the cover plate 31 and discharged from the discharge port 102. At the same time, under the action of the compression spring 34, the clamping plate 322 is synchronously extended from the inside of the cover plate 31.

[0088] When the hopper 2 switches from the inclined material discharge section to the inclined recovery section, the opening of the hopper 2 is set to the lower left under the traction of the chain 11, and the cover plate 31 is reset under the action of the torsion spring 33.

[0089] When the hopper 2 switches from the tilting recovery section to the vertical lifting section, the hopper 2 is turned over under the traction of the chain 11, so that the opening is set upward to facilitate material receiving.

[0090] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
