Description

Technical Field

[0001] The present invention relates to the technical field of fine sand elevators, and more specifically, to a transmission mechanism for a fine sand elevator and a use method thereof. Background Art

[0002] Fine sand elevator is a mechanical equipment specially used for vertical or inclined conveying of bulk materials such as fine sand. It uses the transmission mechanism of the chain driven by an electric motor as a transportation device to make the lifting bucket move within the specified track, and transport fine sand from low to high in an efficient and energy-saving manner. It is widely used in industrial fields such as mines, cement plants, and building materials plants, and has the characteristics of environmental protection, low noise, and strong adaptability.

[0003] At present, when fine sand enters the interior of the elevator, its transmission mechanism will drive multiple containers used to carry fine sand to pass through the position of the feed port in sequence. When the fine sand is poured into the interior of the container, the fine sand will tilt at the opening of the container, that is, the surface of the material pile will form a slope biased towards the position of the feed port. In this case, the heights of the material piles at different positions in the container will be different. After the higher position of the material pile exceeds the container opening, once vibration occurs, some fine sand will be scattered, which will not only cause the fine sand to collide and accumulate with the chain, resulting in reduced lifting efficiency, but also cause accumulation of materials at the bottom of the elevator.

[0004] In order to ensure the normal operation of the transmission mechanism of the existing elevator, an elastic part is arranged at the bottom of the elevator. When fine sand falls, the elastic part will be squeezed, the accumulation of fine sand will continue to increase, and the elastic part will gradually bend downward under the influence of pressure, thereby increasing the accumulation space.

[0005] However, in the actual operation process, the accumulation of fine sand is still inevitable. The accumulation problem still exists. When the amount of fine sand falling from a high place is large, the accumulation phenomenon is particularly serious, which seriously affects the work efficiency. When the accumulation of fine sand is too much, the operation of the lifting bucket will be greatly hindered, and even stuck. In serious cases, it will cause the entire elevator to stop. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the present invention is to provide a transmission mechanism for a fine sand elevator and a method of using the same.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a transmission mechanism for a fine sand elevator, comprising a main body component, a conveying component arranged at the bottom of the main body component, and a flipping component arranged at one side of the conveying component.

[0008] The main component includes a lifting bin, with base plates installed on both sides of the lifting bin, a feed hopper connected to the lower side wall of one of the base plates, and a discharge hopper connected to the upper side wall of the other base plate, two sets of chain transmission components are installed inside the lifting bin, and multiple lifting buckets are installed equidistantly between the two sets of chain transmission components.

[0009] The conveying assembly comprises a first material row bin arranged on the inner bottom wall of the lifting bin and a second material row bin sleeved on the outside of the first material row bin.

[0010] A swing assembly is installed on the inner wall of a base plate corresponding to the feed hopper, and a guide assembly is installed on the side of each lifting hopper away from the base plate.

[0011] The swing assembly comprises two swing rods swingably connected to the inner wall of one of the base plates, and a push block is rotated between the two swing rods.

[0012] The present invention is further configured as follows: the two opposite side walls of the lifting bin are in a through state, the two base plates are respectively located at the two side wall positions of the lifting bin in a through state, an exhaust bin is vertically installed on the top of the lifting bin, and through grooves are respectively opened on the side walls of the two base plates, and the positions of the two through grooves are respectively arranged corresponding to the feed hopper and the discharge hopper, the swing assembly is located above the feed hopper, and a servo motor is installed above the side wall of the lifting bin, and the output end of the servo motor is connected to the chain transmission assembly.

[0013] By adopting the above technical solution, the servo motor drives the corresponding sprocket to rotate, causing the chain to transmit. During the transmission process, the chain pulls the lifting bucket to transmit displacement, thereby achieving the purpose of lifting fine sand. When the lifting bucket is lifted to the highest point, the opening of the lifting bucket gradually tilts to pour the material. When the lifting bucket is transmitted to the other side of the chain, the fine sand inside the lifting bucket is completely discharged, and the discharged fine sand is discharged through the discharge bucket.

[0014] The present invention is further configured as follows: the tops of the first and second row bins are both in an open state, and the first and second row bins are inclined and extended downward from the lifting bin to the outside, and the conveying assembly also includes a collecting bucket arranged on the bottom wall of the lifting bin and a conveyor belt mechanism installed on the bottom of the collecting bucket, one end of the conveyor belt mechanism extends to the outside of the collecting bucket and is arranged corresponding to the first row bin, and a baffle is installed on the side of the collecting bucket close to the first row bin.

[0015] The present invention is further configured as follows: a plurality of baffles are equidistantly connected to the bottom of the baffle, a telescopic cylinder is installed at the bottom of the first row of bins, and a piston rod of the telescopic cylinder is connected to the bottom of the second row of bins.

[0016] By adopting the above technical solution, when part of the fine sand falls to the bottom of the lifting bin during the lifting and pouring process, the fine sand is collected by the collecting bucket and the first row of bins, and then the fine sand is discharged into the first row of bins through the conveyor belt mechanism, and the fine sand slides to the outside of the lifting bin through the inclination angles of the first row of bins and the second row of bins, thereby moving the fine sand out from the bottom of the lifting bin.

[0017] The present invention is further configured as follows: a flip cylinder is hingedly installed on the top of each of the L-shaped tracks, a swing plate is hingedly installed on the top of each of the L-shaped tracks, the piston rod of the flip cylinder is hinged to the side wall of the swing plate, slideways are arranged on the opposite sides of the two L-shaped tracks, sliders are connected to both sides of the slide, the two sliders are respectively arranged corresponding to the two slides, the sliders are slidably connected to the inside of the corresponding slides, and a pull rod is hinged between the bottom of the two swing plates and the side wall of the slide.

[0018] By adopting the above technical solution, the flipping cylinder pushes the swing plate to swing upward, one end of the swing plate pulls the pull rod and the slide to move upward, the slide slides upward along the extension direction of the slide, and the storage box is flipped when it is lifted to the top position of the L-shaped track, and the fine sand is poured back into the interior of the feed hopper, so that the scattered fine sand is reused for the second time.

[0019] The present invention is further configured as follows: the flipping assembly includes a horizontally arranged connecting rod and an L-shaped track connected to both ends of the connecting rod, the height of the two L-shaped tracks is the same as the height of the feed hopper, the side walls of the L-shaped tracks are slidably connected to a slide, a storage box is installed on the side walls of the slide, a flipping cylinder is hingedly installed on the top of each of the L-shaped tracks, a swing plate is hinged on the top of each of the L-shaped tracks, the piston rod of the flipping cylinder is hinged to the side wall of the swing plate, slides are arranged on the opposite sides of the two L-shaped tracks, and sliders are connected to both sides of the slide, the two sliders are respectively arranged corresponding to the two slides, the sliders are slidably connected to the inside of the corresponding slides, and a pull rod is hinged between the bottom of the two swing plates and the side walls of the slide.

[0020] The present invention is further configured as follows: one end of the swing assembly extends between two adjacent lifting buckets, and the swing assembly also includes two fixed blocks installed on the inner walls of the corresponding base plate, a connecting piece is connected between the two fixed blocks, and two positioning plates are symmetrically installed on the top of the connecting piece, and the two positioning plates are rotatably connected to the opposite sides with a rotating rod, the two swing rods are arranged corresponding to the two rotating rods, and the end of the swing rod away from the push block is connected to the outer wall of the corresponding rotating rod.

[0021] The present invention is further configured as follows: the outer side walls of the two rotating rods are sleeved with torsion springs, one end of the torsion spring is connected to the side wall of the corresponding positioning plate, and the other end of the torsion spring is connected to the side wall of the corresponding swing rod.

[0022] The present invention is further configured as follows: a base is provided at the bottom of the push block, and inclined portions are provided around the bottom of the base.

[0023] By adopting the above technical solution, when the lifting bucket rises, it first fits with the push block and then pushes it upward. The swing rod swings synchronously to the horizontal, the torsion spring is twisted, and the push block slides on the top of the lifting bucket to flatten the surface of the fine sand. The lifting bucket continues to rise, the swing rod swings upward, and the push block pulls in the opposite direction for secondary flattening. When the lifting bucket rises to a certain height and separates from the push block, the swing rod is reset by the reaction force of the torsion spring, that is, through the swing of the swing rod and the change of the height of the lifting bucket, the push block can slide on the top of the lifting bucket, thereby achieving the purpose of flattening the material pile, ensuring the stability of the material pile on the top of the lifting bucket and reducing the scattering of fine sand.

[0024] When the push block slides on the surface of the lifting bucket, the bottom surface of the base is in contact with the top of the lifting bucket and the material pile. During the pushing process, the base always keeps in contact with the top of the lifting bucket and the material pile. Through the setting of the inclined portion, the fine sand is scraped and fits the inclined portion, and the inclined portion serves as a guiding slope to guide the fine sand to the arc-shaped outer wall of the push block, so that part of the fine sand can be gradually pushed to a lower position after being impacted, rather than being pushed down directly. The inclined portion is arranged around the bottom of the base, and when the push block slides in the opposite direction, the inclined portion can still play a guiding effect.

[0025] The present invention is further configured as follows: the guide assembly includes a first track installed above the side of the lifting bucket away from the base plate, the interior of the first track is slidably connected to a second track, the side wall of the second track is connected to a U-shaped platform, the inner cavity of the U-shaped platform is arranged toward the opening direction of the lifting bucket, and the top of the U-shaped platform is higher than the corresponding top surface of the lifting bucket.

[0026] By adopting the above technical solution, the lifting bucket continuously conveys the lifting height, and when the lifting bucket is transmitted to the upper position inside the lifting bin, it flips over. The flipped lifting bucket pours out the carried fine sand, and the fine sand is initially guided by the protruding part of the U-shaped platform when it is discharged. When the lifting bucket flips to the other side of the chain transmission assembly, the U-shaped platform stretches due to gravity, and the fine sand is secondary guided by the extended U-shaped platform. The poured fine sand is discharged through the corresponding through groove and the discharge bucket. This setting compensates for the distance between the lifting bucket and the discharge bucket, thereby reducing the amount of fine sand that falls after flipping and pouring.

[0027] A method for using a transmission mechanism for a fine sand elevator, using the transmission mechanism for a fine sand elevator as described above, comprises the following steps: S1. The fine sand to be processed is poured into the feed hopper through the pouring mechanism, and the fine sand enters the interior of the lifting bin through the internal flow channel of the feed hopper. At the same time, the chain transmission assembly drives multiple lifting buckets to drive clockwise inside the lifting bin, and the fine sand is scattered into the interior of the lifting bucket during the flow process.

[0028] S2. When the fine sand enters the lifting bin through the feed hopper, it scatters in a parabolic shape and is carried by one of the lifting buckets. When the lifting bucket continues to be lifted upward, the top of the lifting bucket and the side close to the base plate fit with the bottom surface of the push block. Then the lifting bucket continues to move upward and pushes the push block upward. When the swing rod swings upward to a horizontal state, the bottom surface of the push block slides on the top of the lifting bucket to flatten the surface of the poured fine sand. When the lifting bucket moves upward and the swing rod swings upward at an angle, the push block is pulled in the opposite direction for a second flattening. The lifting bucket continues to move upward, and the push block is separated from the lifting bucket. Then the swing rod swings downward to reset and flattens the next lifting bucket. S3. The lifting bucket continuously conveys the fine sand. When the lifting bucket is transmitted to the upper position inside the lifting bin, it flips over. The lifted bucket after flipping pours out the fine sand it carries. During the pouring process, the guide assembly is used to guide the fine sand.

[0029] S4. When part of the fine sand falls to the bottom of the lifting bin during the lifting and pouring process, the conveying component is used to collect the fallen fine sand, and the fine sand is directly discharged from the lifting bin through the first row bin and the second row bin. The discharged fine sand slides onto the flip component and accumulates. When a certain amount of fine sand accumulates inside the flip component, the conveying component stops conveying, the second row bin is retracted to overlap with the first row bin, the flip component is flipped, and the fine sand is poured back into the feed hopper for secondary lifting.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting a push block, when the bucket rises, it first fits with the push block and then pushes it upward. The swing rod swings synchronously to the horizontal, the torsion spring is twisted, and the push block slides on the top of the bucket to flatten the surface of the fine sand. The bucket continues to rise, the swing rod tilts upward, and the push block pulls in the opposite direction to flatten the surface for the second time. When the bucket rises to a certain height and separates from the push block, the swing rod is reset by the reaction force of the torsion spring, that is, through the swing of the swing rod and the change of the height of the bucket, the push block can slide on the top of the bucket, thereby achieving the purpose of flattening the material pile, ensuring the stability of the material pile on the top of the bucket and reducing the scattering of fine sand.

[0031] (2) When the push block slides on the surface of the lifting bucket, the bottom surface of the base contacts the top of the lifting bucket and the material pile. During the pushing process, the base always maintains contact with the top of the lifting bucket and the material pile. Through the setting of the inclined portion, the fine sand is scraped and fits with the inclined portion, and the inclined portion acts as a guiding slope to guide the fine sand to the curved outer wall of the push block, so that part of the fine sand can be gradually pushed to a lower height position after being impacted, rather than being pushed down directly. The inclined portion is arranged around the bottom of the base. When the push block slides in the opposite direction, the inclined portion can still play a guiding effect.

[0032] (3) The lifting height is continuously conveyed by the lifting bucket. When the lifting bucket is transmitted to the upper position inside the lifting bin, it flips over. After flipping, the lifting bucket pours out the carried fine sand. When the fine sand is discharged, it is initially guided by the protruding part of the U-shaped platform. When the lifting bucket flips to the other side of the chain transmission assembly, the U-shaped platform stretches due to gravity. The fine sand is guided for the second time through the extended U-shaped platform. The poured fine sand is discharged through the corresponding through groove and the discharge bucket. This setting compensates for the distance between the lifting bucket and the discharge bucket, thereby reducing the amount of fine sand that falls after flipping and pouring.

[0033] (4) When a certain amount of fine sand accumulates inside the storage box, the conveyor belt mechanism stops conveying, the piston rod of the telescopic cylinder contracts and drives the second row of silos to retract and overlap with the first row of silos, that is, the second row of silos are retracted from between the two L-shaped tracks. Then the flipping cylinder pushes the swing plate to swing upward, and one end of the swing plate pulls the pull rod and the slide to move upward. The slide slides upward along the extension direction of the slide. When the storage box is lifted to the top position of the L-shaped track, it flips over and the fine sand is poured back into the feed hopper. The scattered fine sand is reused to alleviate the problem of fine sand accumulation at the bottom of the elevator. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0050] See also Figure 1-Figure 13 , the present invention provides the following technical solutions: Embodiment 1, a transmission mechanism for a fine sand elevator, includes a main body component 1, the main body component 1 is used to lift and transport fine sand, and the specific structure of the main body component 1 is as follows: See also Figure 1-Figure 3 The main component 1 includes a lifting bin 15, and two opposite side walls of the lifting bin 15 are in a through state, and base plates 11 are installed on the two through side walls of the lifting bin 15, a feed hopper 12 is connected to the lower side wall of one of the base plates 11, and a discharge hopper 14 is connected to the upper side wall of the other base plate 11, and through grooves 16 are respectively opened on the side walls of the two base plates 11, and the positions of the two through grooves 16 are respectively arranged corresponding to the feed hopper 12 and the discharge hopper 14, the lifting bin 15 and the two base plates 11 are combined to form a chamber for lifting fine sand, the feed hopper 12 and the corresponding through grooves 16 are used to feed the inside of the lifting bin 15, and the discharge hopper 14 and the corresponding through grooves 16 are used to discharge the lifted fine sand inside the lifting bin 15.

[0051] See also Figure 1-Figure 3 Two groups of chain transmission components 17 are installed inside the lifting bin 15, and multiple lifting buckets 18 for loading fine sand are installed equidistantly between the two groups of chain transmission components 17. The chain transmission component 17 is composed of two sprockets and a chain. The two sprockets are respectively installed on the top and bottom of the lifting bin 15, and the two sprockets are connected by a chain. The lifting bucket 18 is installed on the chain, and the lifting bucket 18 is used to load fine sand.

[0052] See also Figure 1-Figure 3 A servo motor 19 is installed above the side wall of the lifting bin 15. The output end of the servo motor 19 is connected to the chain transmission assembly 17. The servo motor 19 is connected to the sprocket on the top of the lifting bin 15, that is, the servo motor 19 drives the corresponding sprocket to rotate, causing the chain to be transmitted. During the transmission process, the chain pulls the lifting bucket 18 to transmit displacement, thereby achieving the purpose of lifting fine sand. When the lifting bucket 18 is lifted to the highest point, the opening of the lifting bucket 18 gradually tilts to pour the material. When the lifting bucket 18 is transmitted to the other side of the chain, the fine sand inside the lifting bucket 18 is completely discharged, and the discharged fine sand is discharged through the discharge bucket 14.

[0053] An exhaust bin 13 is vertically installed on the top of the lifting bin 15, and the exhaust bin 13 is used to guide the smoke and dust generated when the fine sand is discharged, so as to avoid the smoke and dust accumulating inside the lifting bin 15 and causing the staff to be unable to observe the internal situation.

[0054] Although the existing method alleviates the impact of fine sand accumulation on the elevator by changing the size of the space where the fine sand accumulates, fine sand accumulation still exists. The elevator bucket still needs to scoop up the accumulated fine sand each time, but if a lot of fine sand falls, it will still cause the elevator to overload. In this state, the elevator bucket will get stuck or even stop.

[0055] See also Figure 1 , Figure 5 and Figure 6 To this end, a conveying assembly 2 and a flip assembly 3 arranged on one side of the conveying assembly 2 are installed at the bottom of the lifting bin 15. The conveying assembly 2 is used to collect fine sand, and the flip assembly 3 is used to collect and lift the fine sand discharged by the conveying assembly 2 to reduce the amount of fine sand accumulated at the bottom of the elevator. The specific structure of the conveying assembly 2 is as follows: See also Figure 5 and Figure 6 The conveying component 2 includes a collecting hopper 21 arranged on the bottom wall of the lifting bin 15, a first row bin 24 on the bottom wall of the lifting bin 15, and a second row bin 25 sleeved on the outside of the first row bin 24. The tops of the first row bin 24 and the second row bin 25 are both open, and the first row bin 24 and the second row bin 25 are inclined downwardly extended from the lifting bin 15 to the outside. When part of the fine sand falls to the bottom of the lifting bin 15 during the lifting and pouring process, the fine sand is collected by the collecting hopper 21, and then the fine sand is discharged into the first row bin 24 through the conveyor belt mechanism 22, and the fine sand slides to the outside of the lifting bin 15 through the inclination angle of the first row bin 24 and the second row bin 25, thereby moving the fine sand out from the bottom of the lifting bin 15.

[0056] See also Figure 5 and Figure 6 The conveying assembly 2 also includes a conveyor belt mechanism 22 installed at the bottom of the collecting bucket 21, one end of the conveyor belt mechanism 22 extends to the outside of the collecting bucket 21 and is arranged corresponding to the first row of bins 24, a baffle 23 is installed on the side of the collecting bucket 21 close to the first row of bins 24, and a plurality of baffle bars 26 are equidistantly connected to the bottom of the baffle 23, a telescopic cylinder 27 is installed at the bottom of the first row of bins 24, and the piston rod of the telescopic cylinder 27 is connected to the bottom of the second row of bins 25. When fine sand falls, it is first collected by the collecting bucket 21, and the fine sand falls onto the surface of the conveyor belt mechanism 22, and the conveyor belt mechanism 22 drives the fine sand to be transported in the direction of the first row of bins 24, and finally discharged from the interior of the lifting bin 15 through the cooperation of the first row of bins 24 and the second row of bins 25.

[0057] See also Figure 1 and Figure 4The turning assembly 3 includes a horizontally arranged connecting rod 31 and an L-shaped track 32 connected to both ends of the connecting rod 31. The height of the two L-shaped tracks 32 is the same as that of the feed hopper 12. The side wall of the L-shaped track 32 is slidably connected to a slide 34. A storage box 36 is installed on the side wall of the slide 34. The end of the second row of bins 25 away from the first row of bins 24 passes through the two L-shaped tracks 32 and extends to the top of the storage box 36. The fine sand is discharged from the interior of the lifting bin 15 through the first row of bins 24 and the second row of bins 25. It directly slides into the storage box 36, and the fine sand is flattened when passing through the baffle 23 and the baffle bar 26, thereby controlling the stacking height and stacking amount of the fine yarn on the first row of bins 24 to a certain extent, and stably slides into the interior of the storage box 36 to avoid excessive accumulation of fine sand and dust when it falls into the storage box 36.

[0058] See also Figure 4 , a flip cylinder 38 is hingedly installed on the top of each L-shaped track 32, a swing plate 37 is hingedly installed on the top of each L-shaped track 32, the piston rod of the flip cylinder 38 is hinged to the side wall of the swing plate 37, and a slide 33 is arranged on the opposite side of the two L-shaped tracks 32. Slide blocks are connected to both sides of the slide 34. The two slide blocks are respectively arranged corresponding to the two slides 33. The slide blocks are slidably connected to the inside of the corresponding slide 33. A pull rod 35 is hinged between the bottom of the two swing plates 37 and the side wall of the slide 34. When a certain amount of fine sand is accumulated in the storage box 36, the conveyor belt mechanism 22 stops conveying, and the piston rod of the telescopic cylinder 27 contracts and drives the second discharge The bin 25 is retracted and overlapped with the first row bin 24, that is, the second row bin 25 is retracted from between the two L-shaped tracks 32, and then the flipping cylinder 38 pushes the swing plate 37 to swing upward, one end of the swing plate 37 pulls the pull rod 35 and the slide 34 to move upward, and the slide 34 slides upward along the extension direction of the slide 33, and the storage box 36 is flipped when it is lifted to the top position of the L-shaped track 32, and the fine sand is poured back into the interior of the feed hopper 12 for secondary lifting. There is no need to manually shovel out the fine sand or manually collect the discharged material, and then the flipping cylinder 38 contracts, the storage box 36 is reset, and the telescopic cylinder 27 pushes the second row bin 25 to extend again, thereby facilitating the next discharging operation.

[0059] In the second embodiment, even if the fallen fine sand is discharged and lifted again by conveying and transferring, the transfer speed is limited, and a large amount of fallen fine sand will affect the overall lifting efficiency of the elevator.

[0060] For this purpose, see Figure 7-Figure 9A swing assembly 4 is installed on the inner wall of a base plate 11 corresponding to the feed hopper 12, and one end of the swing assembly 4 extends between two adjacent lifting buckets 18. When the lifting buckets 18 collect the incoming fine sand, the swing assembly 4 pushes the material pile to the middle of the lifting bucket 18 or even to the lower position of the material pile, thereby ensuring the stability of the material pile at the top of the lifting bucket 18 and reducing the scattering of fine sand. The specific structure of the swing assembly 4 is as follows: See also Figure 7-Figure 9 and Fig.13 The swing assembly 4 is located above the feed hopper 12. The swing assembly 4 includes two fixed blocks 41 installed on the inner walls of the corresponding base plate 11. A connecting piece 42 is connected between the two fixed blocks 41. Two positioning plates 43 are symmetrically installed on the top of the connecting piece 42. The two positioning plates 43 are rotatably connected to the opposite sides of the two positioning plates 43 with rotating rods 44. A swing rod 46 is connected to the outer wall of each rotating rod 44. The swing rod 46 swings synchronously with the rotating rod 44, and the connecting piece 42 limits the angle of the swing rod 46, that is, the downward swinging angle of the swing rod 46 is limited.

[0061] A push block 47 is rotatably connected between the two swing arms 46. The length of the push block 47 is the same as the width of the lifting bucket 18. The two swing arms 46 are located on both sides of the lifting bucket 18. The push block 47 is used to contact the top of the lifting bucket 18. Through the swing of the swing arm 46 and the change in the height of the lifting bucket 18, the push block 47 can slide on the top of the lifting bucket 18, thereby achieving the purpose of leveling the material pile.

[0062] See also Figure 7-Figure 9 The outer walls of the two rotating rods 44 are sleeved with torsion springs 45, one end of the torsion spring 45 is connected to the side wall of the corresponding positioning plate 43, and the other end of the torsion spring 45 is connected to the side wall of the corresponding swing rod 46. When the lifting bucket 18 continues to be lifted upward, the top of the lifting bucket 18 and the side close to the base plate 11 are in contact with the bottom surface of the push block 47, and then the lifting bucket 18 continues to move upward and pushes the push block 47 to move upward. When the swing rod 46 swings upward to a horizontal state, the torsion spring 45 is twisted, and the bottom surface of the push block 47 slides on the top of the lifting bucket 18 to push the fine sand surface After being pushed flat, the lifting bucket 18 continues to move upward. When the swing arm 46 swings upward at an angle, the push block 47 is pulled in the opposite direction. The swing arm 46 moves to the side wall of the lifting bucket 18 and there is a certain gap between the swing arm 46 and the side wall of the lifting bucket 18. When the push block 47 is pulled in the opposite direction, the secondary pushing flat is completed. When the lifting bucket 18 moves to a certain height so that the push block 47 is separated from the lifting bucket 18, the swing arm 46 swings downward and resets through the reaction force of the torsion spring 45. The connecting piece 42 limits the angle of the swing arm 46, and then the push block 47 pushes the next lifting bucket 18 flat.

[0063] See also Fig.12A base 48 is provided at the bottom of the push block 47, and inclined parts 49 are provided around the bottom of the base 48. A counterweight roller is provided at the bottom of the base 48, and the counterweight roller is used to counterweight the push block 47 as a whole, so that the base 48 is always set downward. When the push block 47 slides on the surface of the lifting bucket 18, the roller fits the surface of the lifting bucket 18, and the bottom surface of the base 48 contacts the top of the lifting bucket 18 and the pile of materials. During the pushing process, the base 48 is always in contact with the top of the lifting bucket 18 and The material pile remains in contact, and the counterweight roller rolls on the surface of the lifting bucket 18. Through the setting of the inclined portion 49, the fine sand is scraped and fits the inclined portion 49. The inclined portion 49 serves as a guiding slope to guide the fine sand to the curved outer wall of the push block 47, so that part of the fine sand can be gradually pushed to a lower position after being impacted, rather than being pushed down directly. The inclined portion 49 is arranged around the bottom of the base 48. When the push block 47 slides in the opposite direction, the inclined portion 49 can still play a guiding effect.

[0064] If there is a lot of fine sand accumulated inside the lifting bucket 18, the accumulated fine sand will fall off in advance when the lifting bucket 18 is turned over to empty the material. By setting the swing component 4, the fine sand at the position of the chain transmission component 17 close to the feed bucket 12 can be adjusted to reduce the amount of fine sand returning and falling. When the lifting bucket 18 is turned over to empty the fine sand, the fine sand in the lifting bucket 18 will gradually pour out in a parabola. Because the lifting bucket 18 is not provided with a guiding mechanism in the emptying direction, part of the fine sand will fall between the lifting bucket 18 and the discharge bucket 14, resulting in the fine sand still falling.

[0065] See also Fig.10 For this purpose, a guide assembly 5 for guiding fine sand is installed on the side of each lifting bucket 18 away from the base plate 11 to achieve a guiding effect and compensate for the distance between the lifting bucket 18 and the discharge bucket 14, thereby reducing the amount of fine sand falling after turning over and dumping. The specific structure of the guide assembly 5 is as follows: See also Fig.10 and Fig.11 The guide assembly 5 includes a first track 51 installed above the side of the lifting bucket 18 away from the base plate 11, the interior of the first track 51 is slidably connected to the second track 52, and the side wall of the second track 52 is connected to a U-shaped platform 53, the inner cavity of the U-shaped platform 53 is arranged toward the opening direction of the lifting bucket 18, the top of the U-shaped platform 53 is higher than the corresponding top surface of the lifting bucket 18, and the lifting height is continuously conveyed by the lifting bucket 18. When the lifting bucket 18 is transmitted to the upper position inside the lifting bin 15, it flips over, and the lifted lifting bucket 18 pours out the carried fine sand. When the fine sand is discharged, it is initially guided by the protruding part of the U-shaped platform 53. When the lifting bucket 18 flips to the other side of the chain transmission assembly 17, the U-shaped platform 53 is extended by gravity, and the fine sand is guided for the second time through the extended U-shaped platform 53, and the poured fine sand is discharged through the corresponding through groove 16 and the discharge bucket 14.

[0066] Embodiment 3, a method for using a transmission mechanism for a fine sand elevator, comprising the following steps: S1. The fine sand to be processed is poured into the feed hopper 12 through the pouring mechanism, and the fine sand enters the lifting bin 15 through the internal flow channel of the feed hopper 12. At the same time, the chain transmission assembly 17 drives multiple lifting bins 18 to drive clockwise inside the lifting bin 15, and the fine sand is scattered into the lifting bin 18 during the flow process.

[0067] The more specific steps of S1 are: S11. The staff pours the fine sand to be processed into the feed hopper 12 through the pouring mechanism. The fine sand enters the lifting bin 15 through the internal flow channel of the feed hopper 12 and the corresponding through groove 16. At the same time, the servo motor 19 drives the chain transmission assembly 17 to transmit. The chain transmission assembly 17 drives multiple lifting bins 18 to transmit clockwise inside the lifting bin 15. The fine sand is scattered into the interior of the lifting bin 18 during the flow process.

[0068] S2. When the fine sand enters the lifting bin 15 through the feed hopper 12, it scatters in a parabolic shape and is carried by one of the lifting buckets 18. When this lifting bucket 18 continues to be lifted upward, the top of the lifting bucket 18 and the side close to the base plate 11 fit with the bottom surface of the push block 47. Then the lifting bucket 18 continues to move upward and pushes the push block 47 upward. When the swing rod 46 swings upward to a horizontal state synchronously, the bottom surface of the push block 47 slides on the top of the lifting bucket 18 to flatten the surface of the poured fine sand. When the lifting bucket 18 moves upward and the swing rod 46 swings upward at an angle, the push block 47 is pulled in the opposite direction for a second flattening. The lifting bucket 18 continues to move upward, and the push block 47 is separated from this lifting bucket 18. Then the swing rod 46 swings downward to reset and flattens the next lifting bucket 18.

[0069] The more specific steps of S2 are: S21. When the fine sand enters the lifting bin 15 through the feed hopper 12, it scatters in a parabolic shape and is carried by one of the lifting buckets 18. When the lifting bucket 18 continues to be lifted upward, the top of the lifting bucket 18 and the side close to the base plate 11 fit with the bottom surface of the push block 47. Then the lifting bucket 18 continues to move upward and pushes the push block 47 upward. When the swing rod 46 swings upward to a horizontal state synchronously, the torsion spring 45 is twisted, and the bottom surface of the push block 47 slides on the top of the lifting bucket 18 to flatten the surface of the poured fine sand.

[0070] S22, the lifting bucket 18 continues to move upward, and when the swing rod 46 swings upward at an angle, the push block 47 is pulled in the opposite direction to perform a second flattening. When the lifting bucket 18 moves to a certain height so that the push block 47 is separated from the lifting bucket 18, the swing rod 46 swings downward and resets due to the reaction force of the torsion spring 45, and the connecting piece 42 limits the angle of the swing rod 46, and then the push block 47 flattens the next lifting bucket 18.

[0071] S3, the lifting bucket 18 continuously conveys the fine sand, and when the lifting bucket 18 is transmitted to the upper position inside the lifting bin 15, it flips over. The lifted bucket 18 after flipping pours out the carried fine sand, and the poured fine sand is discharged through the discharge bucket 14. During the pouring process, the guide assembly 5 is used to guide the fine sand, and the fine sand is poured toward the discharge bucket 14.

[0072] The more specific steps of S3 are: S31. The lifting height is continuously conveyed by the lifting bucket 18. When the lifting bucket 18 is transmitted to the upper position inside the lifting bin 15, it flips over. The lifted bucket 18 after flipping pours out the carried fine sand. When the fine sand is discharged, it is initially guided by the protruding part of the U-shaped platform 53. When the lifting bucket 18 flips over to the other side of the chain transmission assembly 17, the U-shaped platform 53 stretches due to gravity. The fine sand is guided for the second time through the extended U-shaped platform 53. The poured fine sand is discharged through the corresponding through groove 16 and the discharge bucket 14.

[0073] S4. When part of the fine sand falls to the bottom of the lifting bin 15 during the lifting and pouring process, the conveying component 2 is used to collect the fallen fine sand, and the fine sand is directly discharged from the lifting bin 15 through the first row bin 24 and the second row bin 25. The discharged fine sand slides into the storage box 36 and accumulates. When a certain amount of fine sand accumulates inside the storage box 36, the conveying component 2 stops conveying, the second row bin 25 is retracted to overlap with the first row bin 24, and the storage box 36 moves up along the extension direction of the L-shaped track 32 and the slide 33 and completes the flipping, and the fine sand is poured back into the interior of the feed hopper 12 for secondary lifting.

[0074] The more specific steps of S4 are: S41. When part of the fine sand falls to the bottom of the lifting bin 15 during the lifting and pouring process, the fine sand is collected by the collecting bucket 21 and the first row bin 24. Then, the fine sand is discharged into the first row bin 24 through the conveyor belt mechanism 22. The fine sand slides to the outside of the lifting bin 15 through the inclination angle of the first row bin 24 and the second row bin 25, and finally falls into the storage box 36 and accumulates.

[0075] S42. When a certain amount of fine sand is accumulated inside the storage box 36, the conveyor belt mechanism 22 stops conveying, the piston rod of the telescopic cylinder 27 contracts and drives the second row of material bins 25 to be retracted and overlapped with the first row of material bins 24, that is, the second row of material bins 25 are retracted from between the two L-shaped tracks 32, and then the flipping cylinder 38 pushes the swing plate 37 to swing upward, and one end of the swing plate 37 pulls the pull rod 35 and the slide 34 to move upward, and the slide 34 slides upward along the extension direction of the slide 33. When the storage box 36 is lifted to the top position of the L-shaped track 32, it flips over, and the fine sand is poured back into the interior of the feed hopper 12 for a second lift.
