Description

Technical Field

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

[0002] A fine sand elevator is a mechanical device specifically used for vertically or obliquely conveying bulk materials such as fine sand. It uses a transmission mechanism driven by an electric motor to drive a chain as a transportation device, enabling the lifting bucket to move within a specified track, efficiently and energy-savingly conveying fine sand from a lower position to a higher position. It is widely used in industrial fields such as mines, cement plants, and building material factories, and has characteristics such as environmental protection, low noise, and strong adaptability.

[0003] Currently, when fine sand enters the interior of the elevator, its transmission mechanism drives multiple containers for carrying fine sand to pass through the position of the feed inlet in sequence. When the fine sand is poured into the interior of the container, the fine sand will be inclined at the opening of the container, that is, a slope biased towards the position of the feed inlet will be formed on the surface of the material pile. In this case, the height of the material piles at different positions in the container will be different. Once vibration occurs when the height of the material pile at a higher position exceeds the opening of the container, some fine sand will be scattered, which not only causes the fine sand to collide and accumulate with the chain, resulting in a reduction in the lifting efficiency, but also causes the accumulation of materials at the bottom of the elevator.

[0004] In order to ensure the normal operation of the transmission mechanism, an existing elevator is provided with an elastic member at the bottom of the elevator. When the fine sand drops, it will squeeze the elastic member. As the accumulation amount of the fine sand continuously increases, the elastic member will gradually bend downward under the influence of the pressure, thereby increasing the accumulation space.

[0005] However, in the actual operation process, the situation of fine sand accumulation will still inevitably occur. The accumulation problem still exists, and when the amount of fine sand falling from a high position is large, the accumulation phenomenon is particularly serious, seriously affecting the work efficiency. When the accumulated fine sand is too much, the operation of the lifting bucket will be greatly hindered, and even jamming may occur, and in severe cases, it may even cause the entire elevator to stall. Summary of the Invention

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a transmission mechanism for a fine sand elevator and its usage method.

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

[0008] The main body component includes a lifting bin, on both sides of which are installed substrates. Below the side wall of one of the substrates is connected with a feed hopper, and above the side wall of the other substrate is connected with a discharge hopper. Inside the lifting bin are installed two sets of chain drive components, and between the two sets of chain drive components are equidistantly installed a plurality of lifting buckets.

[0009] The conveying component includes a first discharge bin arranged on the inner bottom wall of the lifting bin and a second discharge bin sleeved outside the first discharge bin.

[0010] On the inner wall of one of the substrates corresponding to the feed hopper is installed a swinging component, and on the side of each lifting bucket away from the substrate is installed a guiding and discharging component.

[0011] The swinging component includes two swinging rods swingably connected to the inner wall of one of the substrates, and a pushing block is rotatably arranged between the two swinging rods.

[0012] The present invention is further configured as follows: both opposite side walls of the lifting bin are in a through state, and the two substrates are respectively located at the positions of the two through side walls of the lifting bin. Vertically installed at the top of the lifting bin is an exhaust bin. Through slots are respectively opened on the side walls of the two substrates, and the positions of the two through slots are respectively corresponding to the feed hopper and the discharge hopper. The swinging component is located above the feed hopper. 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 drive component.

[0013] By adopting the above technical solution, the servo motor drives the corresponding sprocket to rotate, causing the chain to drive. During the driving process of the chain, the lifting bucket is pulled to drive and displace, so as to achieve the purpose of lifting the fine sand. When the lifting bucket is lifted to the highest point, the opening of the lifting bucket gradually inclines to dump the material. When the lifting bucket is driven 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 hopper.

[0014] The present invention is further configured as follows: the tops of the first discharge bin and the second discharge bin are both in an open state, and the first discharge bin and the second discharge bin extend obliquely downward from the lifting bin to the outside. The conveying component further includes a collecting hopper arranged on the inner bottom wall of the lifting bin and a conveyor belt mechanism installed at the bottom of the collecting hopper. One end of the conveyor belt mechanism extends outside the collecting hopper and corresponds to the first discharge bin. A baffle is installed on one side of the collecting hopper close to the first discharge bin.

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

[0016] By adopting the above technical solution, when some fine sand falls to the bottom of the lifting bin during the lifting and discharging process, the fine sand is collected by the collecting hopper and the first discharging bin, and then the fine sand is discharged into the first discharging bin through the transmission of the conveyor belt mechanism. Moreover, the fine sand slides out of the bottom of the lifting bin by virtue of the inclination angles of the first discharging bin and the second discharging bin.

[0017] The present invention is further configured as follows: a tipping cylinder is hingedly installed at the top of each of the L-shaped tracks, a swing plate is hinged at the top of each of the L-shaped tracks, the piston rod of the tipping cylinder is hingedly connected to the side wall of the swing plate, slide ways are arranged on one side of the two L-shaped tracks facing each other, sliders are connected to both sides of the slide table, the two sliders are respectively arranged corresponding to the two slide ways, the sliders are slidably connected to the interiors of the corresponding slide ways, and a pull rod is hingedly connected between the bottoms of the two swing plates and the side wall of the slide table.

[0018] By adopting the above technical solution, the tipping cylinder pushes the swing plate to swing upward, one end of the swing plate pulls the pull rod and the slide table to move upward, the slide table slides upward along the extension direction of the slide way, and when the storage box is lifted to the top position of the L-shaped track, it turns over, and the fine sand is poured back into the interior of the feed hopper, realizing the secondary utilization of the scattered fine sand.

[0019] The present invention is further configured as follows: the tipping assembly includes a horizontally arranged connecting rod and L-shaped tracks connected to both ends of the connecting rod. The heights of the two L-shaped tracks are the same as the height of the feed hopper. A slide table is slidably connected to the side wall of the L-shaped track, a storage box is installed on the side wall of the slide table, a tipping cylinder is hingedly installed at the top of each of the L-shaped tracks, a swing plate is hinged at the top of each of the L-shaped tracks, the piston rod of the tipping cylinder is hingedly connected to the side wall of the swing plate, slide ways are arranged on one side of the two L-shaped tracks facing each other, sliders are connected to both sides of the slide table, the two sliders are respectively arranged corresponding to the two slide ways, the sliders are slidably connected to the interiors of the corresponding slide ways, and a pull rod is hingedly connected between the bottoms of the two swing plates and the side wall of the slide table.

[0020] The present invention is further configured as follows: one end of the swinging assembly extends between two adjacent lifting buckets. The swinging assembly further includes two fixing blocks installed on the inner wall of the corresponding substrate, a connecting member is connected between the two fixing blocks, two positioning plates are symmetrically installed on the top of the connecting member, a rotating rod is rotatably connected to one side of each of the two positioning plates facing away from each other, the two swinging rods are arranged corresponding to the two rotating rods, and the end of the swinging rod away from the pushing block is connected to the outer wall of the corresponding rotating rod.

[0021] The present invention is further configured such that torsion springs are sleeved on the outer side walls of both of the rotating rods. One end of each torsion spring is connected to the side wall of the corresponding positioning plate, and the other end of each torsion spring is connected to the side wall of the corresponding swing rod.

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

[0023] By adopting the above technical solution, when the lifting bucket ascends, it first fits with the push block and then is pushed upward. The swing rod swings synchronously to the horizontal position, the torsion spring is twisted, the push block slides on the top of the lifting bucket, leveling the surface of the fine sand. The lifting bucket continues to ascend, the swing rod swings upward obliquely, and the push block pulls back in the reverse direction for secondary leveling. When the lifting bucket rises to a certain height and disengages from the push block, the swing rod resets by the reaction force of the torsion spring. That is, through the swing of the swing rod and the change in the height of the lifting bucket, the push block can slide on the top of the lifting bucket, thereby achieving the purpose of leveling 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 platform contacts the top of the lifting bucket and the material pile. During the pushing process, the base platform always remains in contact with the top of the lifting bucket and the material pile. Through the setting of the inclined portions, the fine sand is scraped and fits with the inclined portions, and the inclined portions, as guiding inclined surfaces, guide the fine sand onto the arc-shaped outer wall of the push block. Thus, part of the fine sand can be gradually pushed to a lower height after being impacted, rather than being directly pushed down. The inclined portions are provided around the bottom of the base platform, and when the push block slides in the reverse direction, the inclined portions can still play a guiding role.

[0025] The present invention is further configured such that the guiding and discharging assembly includes a first track installed above the side of the lifting bucket away from the base plate. A second track is slidably connected inside the first track. A U-shaped platform is connected to the side wall of the second track. The inner cavity of the U-shaped platform is arranged towards the opening direction of the lifting bucket, and the top of the U-shaped platform is higher than the top surface of the corresponding lifting bucket.

[0026] By adopting the above technical solution, the lifting bucket continuously conveys and raises its height. 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. 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 extends under the influence of gravity, and the fine sand is secondarily guided by the lengthened U-shaped platform. The poured fine sand is discharged through the corresponding through slots and discharge hoppers. This setting compensates for the distance between the lifting bucket and the discharge hopper, thereby reducing the amount of fine sand that drops after flipping and discharging.

[0027] A usage method of a transmission mechanism for a fine sand elevator, using a transmission mechanism for a fine sand elevator as described above, includes the following steps:

[0028] S1. The fine sand to be processed is poured into the interior of the feed hopper through the tipping mechanism. 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 drive assembly drives a plurality of lifting buckets to rotate clockwise inside the lifting bin, and the fine sand scatters into the interior of the lifting buckets during the flowing process.

[0029] S2. When the fine sand enters the interior of the lifting bin through the feed hopper, it scatters in a parabolic shape and is carried by one of the lifting buckets. When this lifting bucket continues to lift upward, the side of the top of the lifting bucket close to the substrate fits against the bottom surface of the push block. Then, as the lifting bucket continues to move upward, it pushes the push block upward. When the swing rod swings upward synchronously to the horizontal state, the bottom surface of the push block slides on the top of the lifting bucket to level the surface of the poured fine sand. When the lifting bucket moves upward and the swing rod swings obliquely upward, the push block is pulled in the reverse direction for secondary leveling. As the lifting bucket continues to move upward, the push block disengages from this lifting bucket. Then, the swing rod swings downward to reset and levels the next lifting bucket.

[0030] S3. Through continuous transportation by the lifting buckets, when the lifting buckets are driven to the upper position inside the lifting bin, they flip over, and the flipped lifting buckets pour out the carried fine sand. During the pouring process, the guide and discharge assembly is used to cooperate to guide the fine sand.

[0031] S4. When some fine sand falls to the bottom of the lifting bin during the lifting and pouring process, the conveying assembly is used to collect the fallen fine sand. The fine sand is directly discharged from the lifting bin through the first discharge bin and the second discharge bin. The discharged fine sand slides onto the flipping assembly and accumulates. When a certain amount of fine sand accumulates inside the flipping assembly, the conveying assembly stops conveying. The second discharge bin retracts and overlaps with the first discharge bin, and the flipping assembly flips, and the fine sand is poured back into the interior of the feed hopper for secondary lifting.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] (1) By setting the push block, when the lifting bucket rises, it first fits against 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 level the surface of the fine sand. As the lifting bucket continues to rise and the swing rod swings obliquely upward, the push block is pulled in the reverse direction for secondary leveling. When the lifting bucket rises to a certain height and disengages from the push block, the swing rod resets by the reaction force of the torsion spring. That is, through the swing of the swing rod and the change in the height of the lifting bucket, the push block can slide on the top of the lifting bucket, thereby achieving the purpose of leveling the material pile, ensuring the stability of the material pile on the top of the lifting bucket, and reducing the scattering of fine sand.

[0034] (2)When the pushing block slides on the surface of the lifting bucket, the bottom surface of the base platform contacts the top of the lifting bucket and the material pile. During the pushing process, the base platform always remains in contact with the top of the lifting bucket and the material pile. Through the setting of the inclined part, the fine sand is scraped and fits with the inclined part, and the inclined part, as a guiding inclined plane, guides the fine sand onto the arc-shaped outer wall of the pushing block. Thus, part of the fine sand can be gradually pushed to a lower position after being impacted instead of being directly pushed down. The inclined part is arranged around the bottom of the base platform, and when the pushing block slides in the reverse direction, the inclined part can still play a guiding role.

[0035] (3)By continuously transporting and lifting the height of the lifting bucket, when the lifting bucket is transmitted to the upper position inside the lifting bin, it flips. 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 elongates under the influence of gravity, and the fine sand is secondarily guided by the lengthened U-shaped platform. The discharged fine sand is discharged through the corresponding through slots and the discharge hopper. This setting compensates for the distance between the lifting bucket and the discharge hopper, thereby reducing the amount of fine sand that falls after flipping and discharging.

[0036] (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 discharge bin to retract and overlap with the first discharge bin, that is, the second discharge bin retracts 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 sliding table upward. The sliding table slides upward along the extension direction of the slideway. When the storage box is lifted to the top position of the L-shaped track, it flips, and the fine sand is poured back into the inside of the feed hopper, reusing the scattered fine sand and alleviating the problem of fine sand accumulation at the bottom of the elevator.

[0054] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0055] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0056] Please refer toFigures 1 - 13 , the present invention provides the following technical solutions:

[0057] Embodiment 1, a transmission mechanism for a fine sand elevator, including a main body assembly 1, the main body assembly 1 is used for lifting and conveying fine sand, and the specific structure of the main body assembly 1 is as follows:

[0058] Refer to Figures 1 - 3 , the main body assembly 1 includes a lifting bin 15. Both opposite side walls of the lifting bin 15 are in a through state, and base plates 11 are installed on both side walls of the lifting bin 15 in a through state. 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. Through slots 16 are respectively opened on the side walls of the two base plates 11, and the positions of the two through slots 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 form a chamber for lifting fine sand. The feed hopper 12 and the corresponding through slot 16 cooperate to supply materials to the inside of the lifting bin 15, while the discharge hopper 14 and the corresponding through slot 16 cooperate to discharge the lifted fine sand inside the lifting bin 15.

[0059] Refer to Figures 1 - 3 , two sets of chain drive assemblies 17 are installed inside the lifting bin 15. A plurality of lifting buckets 18 for loading fine sand are installed at equal intervals between the two sets of chain drive assemblies 17. The chain drive assembly 17 is composed of two sprockets and a chain. The two sprockets are respectively installed at 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 for loading fine sand.

[0060] Refer to Figures 1 - 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 drive assembly 17. The servo motor 19 is connected to the sprocket above the inside of the lifting bin 15, that is, the servo motor 19 drives the corresponding sprocket to rotate, causing the chain to drive. During the transmission process of the chain, the lifting bucket 18 is pulled to drive and displace, 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 inclines to pour materials. When the lifting bucket 18 is driven 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 hopper 14.

[0061] An exhaust bin 13 is vertically installed at the top of the lifting bin 15, and the exhaust bin 13 is used for guiding the smoke and dust generated during the fine sand discharging to avoid the problem that the smoke and dust accumulate inside the lifting bin 15 and cause the staff to be unable to observe the internal situation.

[0062] Although the existing method alleviates the impact of fine sand accumulation on the elevator by changing the spatial size of the fine sand accumulation position, there will still be a situation of fine sand accumulation. Each lifting bucket still needs to scoop up the accumulated fine sand. However, if there is a large amount of dropped fine sand, it will still cause the elevator to operate overloaded, and in this state, the lifting bucket may get stuck or even stop.

[0063] Refer to Figure 1 , Figure 5 and Figure 6 , for this reason, a conveying component 2 is installed at the bottom of the lifting bin 15 and a turning component 3 is arranged on one side of the conveying component 2. The conveying component 2 is used to collect fine sand, and the turning component 3 is used to collect and lift the fine sand discharged by the conveying component 2, reducing the amount of fine sand accumulated at the bottom of the elevator. The specific structure of the conveying component 2 is as follows:

[0064] Refer to Figure 5 and Figure 6 , the conveying component 2 includes a collecting hopper 21 arranged on the inner bottom wall of the lifting bin 15, a first discharge bin 24 on the inner bottom wall of the lifting bin 15, and a second discharge bin 25 sleeved outside the first discharge bin 24. The tops of the first discharge bin 24 and the second discharge bin 25 are both in an open state, and the first discharge bin 24 and the second discharge bin 25 extend obliquely downward from the lifting bin 15 to the outside. When some fine sand drops to the bottom of the lifting bin 15 during the lifting and discharging process, the collecting hopper 21 is used to collect the fine sand. Then, the fine sand is conveyed into the first discharge bin 24 by the conveyor belt mechanism 22, and the fine sand slides out of the bottom of the lifting bin 15 along the inclination angles of the first discharge bin 24 and the second discharge bin 25.

[0065] Refer to Figure 5 and Figure 6 , the conveying component 2 further includes a conveyor belt mechanism 22 installed at the bottom of the collecting hopper 21. One end of the conveyor belt mechanism 22 extends outside the collecting hopper 21 and is arranged corresponding to the first discharge bin 24. A baffle 23 is installed on one side of the collecting hopper 21 close to the first discharge bin 24. A plurality of retaining bars 26 are equidistantly connected to the bottom of the baffle 23. A telescopic cylinder 27 is installed at the bottom of the first discharge bin 24, and the piston rod of the telescopic cylinder 27 is connected to the bottom of the second discharge bin 25. When the fine sand drops, first, the collecting hopper 21 is used to collect it, and the fine sand drops onto the surface of the conveyor belt mechanism 22. Then, the conveyor belt mechanism 22 drives the fine sand to be conveyed towards the first discharge bin 24, and finally, it is discharged from the inside of the lifting bin 15 through the cooperation of the first discharge bin 24 and the second discharge bin 25.

[0066] Refer to Figure 1 and Figure 4, the flipping assembly 3 includes a horizontally arranged connecting rod 31 and L-shaped tracks 32 connected to both ends of the connecting rod 31. The heights of the two L-shaped tracks 32 are the same as the height of the feed hopper 12. A sliding table 34 is slidably connected to the side wall of the L-shaped track 32. A storage box 36 is installed on the side wall of the sliding table 34. One end of the second discharge bin 25 away from the first discharge bin 24 passes between the two L-shaped tracks 32 and extends to the top of the storage box 36. Fine sand is discharged from the inside of the lifting bin 15 through the cooperation of the first discharge bin 24 and the second discharge bin 25 and directly slides into the inside of the storage box 36. When the fine sand passes through the baffle 23 and the bar 26, it is leveled, thereby controlling to a certain extent the stacking height and stacking amount of the fine sand on the first discharge bin 24, stably sliding into the inside of the storage box 36, and avoiding the situation of dust raising when a large amount of fine sand accumulates and falls into the inside of the storage box 36.

[0067] Refer to Figure 4 , a flipping cylinder 38 is hingedly installed on the top of each L-shaped track 32. A swing plate 37 is hinged to the top of each L-shaped track 32. The piston rod of the flipping cylinder 38 is hinged to the side wall of the swing plate 37. Slideways 33 are provided on the opposite sides of the two L-shaped tracks 32. Sliders are connected to both sides of the sliding table 34. The two sliders are respectively arranged corresponding to the two slideways 33. The sliders are slidably connected to the inside of the corresponding slideways 33. A pull rod 35 is hinged between the bottoms of the two swing plates 37 and the side wall of the sliding table 34. When a certain amount of fine sand accumulates 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 discharge bin 25 to retract and overlap with the first discharge bin 24, that is, the second discharge bin 25 retracts from between the two L-shaped tracks 32. 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 sliding table 34 to move upward. The sliding table 34 slides upward along the extension direction of the slideway 33. When the storage box 36 is lifted to the top position of the L-shaped track 32, it flips, and the fine sand is poured back into the inside of the feed hopper 12 for secondary lifting. There is no need for manual shoveling of the fine sand and no need for manual collection and dumping. Then the flipping cylinder 38 contracts, the storage box 36 resets, and the telescopic cylinder 27 pushes the second discharge bin 25 to extend again, thereby facilitating the next discharging operation.

[0068] Embodiment 2. Even if the dropped fine sand is discharged and re-lifted by means of conveying and transferring, the transfer speed is limited, and the dropping of a large amount of fine sand will affect the overall lifting efficiency of the elevator.

[0069] Therefore, refer to Figures 7 - 9, a swing assembly 4 is installed on the inner wall of a substrate 11 corresponding to the feed hopper 12. One end of the swing assembly 4 extends between two adjacent lifting hoppers 18. When the lifting hoppers 18 collect the incoming fine sand, the swing assembly 4 pushes the material pile towards the middle of the lifting hoppers 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 hoppers 18 and reducing the scattering of the fine sand. The specific structure of the swing assembly 4 is as follows:

[0070] Refer to Figures 7 - 9 and Figure 13 , the swing assembly 4 is located above the feed hopper 12. The swing assembly 4 includes two fixing blocks 41 installed on the inner wall of the corresponding substrate 11. A connecting piece 42 is connected between the two fixing blocks 41. Two positioning plates 43 are symmetrically installed on the top of the connecting piece 42. A rotating rod 44 is rotatably connected to each side of the two positioning plates 43 facing away from each other. 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 swing angle of the swing rod 46 is restricted.

[0071] A push block 47 is rotatably connected between the two swing rods 46. The length of the push block 47 is the same as the width of the lifting hopper 18. The two swing rods 46 are located on both sides of the lifting hopper 18. The push block 47 is used to contact the top of the lifting hopper 18. Through the swing of the swing rod 46 and the change in the height of the lifting hopper 18, the push block 47 can slide on the top of the lifting hopper 18, thereby achieving the purpose of leveling the material pile.

[0072] Refer to Figures 7 - 9 , torsion springs 45 are sleeved on the outer side walls of the two rotating rods 44. 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 hopper 18 continues to lift upward, the top of the lifting hopper 18 and the side close to the substrate 11 are attached to the bottom surface of the push block 47. Then the lifting hopper 18 continues to move upward and pushes the push block 47 upward. When the swing rod 46 swings upward to the horizontal state synchronously, the torsion spring 45 is twisted. The bottom surface of the push block 47 slides on the top of the lifting hopper 18 to level the surface of the poured fine sand. When the lifting hopper 18 continues to move upward and the swing rod 46 swings obliquely upward, the push block 47 is pulled in the reverse direction. When the swing rod 46 moves to the side wall position of the lifting hopper 18 and there is a certain gap between the swing rod 46 and the side wall of the lifting hopper 18, the push block 47 is pulled in the reverse direction to complete the secondary leveling. When the lifting hopper 18 moves to a certain height and the push block 47 is separated from this lifting hopper 18, the swing rod 46 swings downward to reset through the reaction force of the torsion spring 45. The connecting piece 42 limits the angle of the swing rod 46, and then the push block 47 levels the next lifting hopper 18.

[0073] Refer to Figure 12, a base platform 48 is provided at the bottom of the pushing block 47. Inclined portions 49 are provided around the bottom of the base platform 48. A counterweight roller is provided at the bottom of the base platform 48. The counterweight roller is used to counterweight the whole pushing block 47, so that the base platform 48 always remains downward. When the pushing block 47 slides on the surface of the lifting bucket 18, the roller fits with the surface of the lifting bucket 18, and the bottom surface of the base platform 48 contacts the top of the lifting bucket 18 and the material pile. During the pushing process, the base platform 48 always remains in contact with the top of the lifting bucket 18 and the material pile. 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 with the inclined portion 49, and the inclined portion 49, as a guiding inclined surface, guides the fine sand onto the arc-shaped outer wall of the pushing block 47. Then, part of the fine sand can be gradually pushed to a lower position after being impacted, rather than being directly pushed down. The inclined portions 49 are provided around the bottom of the base platform 48. When the pushing block 47 slides in the reverse direction, the inclined portions 49 can still play a guiding role.

[0074] If there is a large amount of fine sand accumulated inside the lifting bucket 18, when the lifting bucket 18 is flipped for discharging, the accumulated fine sand will fall in advance. Through the setting of the swinging assembly 4, the fine sand near the feeding hopper 12 of the chain transmission assembly 17 can be adjusted, reducing the amount of fine sand falling back during the return. When the lifting bucket 18 is flipped to discharge the fine sand, the fine sand in the lifting bucket 18 will gradually pour out in a parabola. Since no guiding mechanism is provided in the discharging direction of the lifting bucket 18, part of the fine sand will fall between the lifting bucket 18 and the discharging hopper 14, resulting in the situation that the fine sand will still fall.

[0075] Refer to Figure 10 , for this reason, a guiding and discharging assembly 5 for fine sand diversion is installed on one 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 discharging hopper 14, thereby reducing the amount of fine sand falling after flipping and discharging. The specific structure of the guiding and discharging assembly 5 is as follows:

[0076] Refer to Figure 10 and Figure 11 , the guiding and discharging assembly 5 includes a first track 51 installed above one side of the lifting bucket 18 away from the base plate 11. A second track 52 is slidably connected inside the first track 51. A U-shaped platform 53 is connected to the side wall of the second track 52. The inner cavity of the U-shaped platform 53 is arranged towards the opening direction of the lifting bucket 18. The top of the U-shaped platform 53 is higher than the top surface of the corresponding lifting bucket 18. Through the continuous lifting height of the lifting bucket 18, when the lifting bucket 18 is transmitted to the upper position inside the lifting bin 15, it flips. The flipped 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 extends under the influence of gravity, and the fine sand is secondarily guided by the lengthened U-shaped platform 53. The discharged fine sand is discharged through the corresponding through slots 16 and the discharging hopper 14.

[0077] Embodiment 3, a method of using a transmission mechanism for a fine sand elevator, comprising the following steps:

[0078] S1. The fine sand to be processed is poured into the interior of the feed hopper 12 through the tipping mechanism. The fine sand enters the interior of the lifting bin 15 through the flow channel inside the feed hopper 12. At the same time, the chain drive assembly 17 drives a plurality of lifting buckets 18 to rotate clockwise inside the lifting bin 15, and the fine sand scatters into the interior of the lifting buckets 18 during the flowing process.

[0079] The more specific steps of S1 are:

[0080] S11. The staff pours the fine sand to be processed into the interior of the feed hopper 12 through the tipping mechanism. The fine sand enters the interior of the lifting bin 15 through the flow channel inside the feed hopper 12 and the corresponding through slots 16. At the same time, the servo motor 19 drives the chain drive assembly 17 to drive, and the chain drive assembly 17 drives a plurality of lifting buckets 18 to rotate clockwise inside the lifting bin 15, and the fine sand scatters into the interior of the lifting buckets 18 during the flowing process.

[0081] S2. When the fine sand enters the interior of 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 lift upward, the side of the top of the lifting bucket 18 close to the base plate 11 fits against 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 synchronously to the horizontal state, the bottom surface of the push block 47 slides on the top of the lifting bucket 18 to level the surface of the poured fine sand. When the lifting bucket 18 moves upward and the swing rod 46 swings obliquely upward, the push block 47 is pulled in the reverse direction for secondary leveling. When the lifting bucket 18 continues to move upward, the push block 47 disengages from this lifting bucket 18. Then the swing rod 46 swings downward to reset and levels the next lifting bucket 18.

[0082] The more specific steps of S2 are:

[0083] S21. When the fine sand enters the interior of 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 lift upward, the side of the top of the lifting bucket 18 close to the base plate 11 fits against 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 synchronously to the 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 level the surface of the poured fine sand.

[0084] S22. The lifting bucket 18 continues to move upward. When the swing rod 46 swings obliquely upward, the push block 47 is pulled in the opposite direction for secondary leveling. When the lifting bucket 18 moves to a certain height and the push block 47 disengages from this lifting bucket 18, the swing rod 46 swings downward and resets under the reaction force of the torsion spring 45. The connecting member 42 limits the angle of the swing rod 46. Then, the push block 47 levels the next lifting bucket 18.

[0085] S3. Through continuous conveyance by the lifting bucket 18, when the lifting bucket 18 is transmitted to the upper position inside the lifting bin 15, it flips. The flipped lifting bucket 18 pours out the fine sand it carries. The poured fine sand is discharged through the discharge hopper 14. During the pouring process, the guiding and discharging assembly 5 is used to guide the fine sand, and the fine sand is poured in the direction of the discharge hopper 14.

[0086] The more specific steps of S3 are as follows:

[0087] S31. Through continuous conveyance and lifting of the lifting bucket 18, when the lifting bucket 18 is transmitted to the upper position inside the lifting bin 15, it flips. The flipped lifting bucket 18 pours out the fine sand it carries. 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 drive assembly 17, the U-shaped platform 53 elongates under the influence of gravity, and the fine sand is secondarily guided by the elongated U-shaped platform 53. The poured fine sand is discharged through the corresponding through slot 16 and the discharge hopper 14.

[0088] S4. When some fine sand falls to the bottom of the lifting bin 15 during lifting and pouring, the conveying assembly 2 is used to collect the fallen fine sand. The fine sand is directly discharged from the lifting bin 15 through the first discharge bin 24 and the second discharge bin 25. The discharged fine sand slides into the interior of the storage box 36 and accumulates. When a certain amount of fine sand has accumulated inside the storage box 36, the conveying assembly 2 stops conveying. The second discharge bin 25 retracts and overlaps with the first discharge bin 24. The storage box 36 moves upward along the extension directions of the L-shaped track 32 and the slideway 33 and completes flipping, and the fine sand is poured back into the interior of the feed hopper 12 for secondary lifting.

[0089] The more specific steps of S4 are as follows:

[0090] S41. When some fine sand falls to the bottom of the lifting bin 15 during lifting and pouring, the collecting hopper 21 and the first discharge bin 24 are used to collect the fine sand. Then, the fine sand is conveyed by the conveyor belt mechanism 22 and discharged into the interior of the first discharge bin 24. And the fine sand slides out of the lifting bin 15 through the inclination angles of the first discharge bin 24 and the second discharge bin 25, and finally falls into the interior of the storage box 36 and accumulates.

[0091] S42. After a certain amount of fine sand has 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 discharging bin 25 to retract and overlap with the first discharging bin 24, that is, the second discharging bin 25 retracts from between the two L-shaped tracks 32. Then, the tilting cylinder 38 pushes the swing plate 37 to swing upward. One end of the swing plate 37 pulls the pull rod 35 and the sliding table 34 to move upward. The sliding table 34 slides upward along the extension direction of the slideway 33. When the storage box 36 is lifted to the top position of the L-shaped track 32, it turns over, and the fine sand is poured back into the inside of the feed hopper 12 for secondary lifting.
