[0001] The invention relates to the technical field of lifting equipment, in particular to a high-efficiency bucket elevator. Background Art

[0002] Bucket elevators are common conveying machinery and are widely used in industries such as cement, mining, chemicals and grain. They lift materials through a lifting bucket. In the actual working process of existing bucket elevators, due to the gap in the feeding part of the bucket elevator, the material falls into the lower section of the bucket elevator, and the material does not completely fall from the top of the bucket elevator to the lower section of the bucket elevator when it is discharged, so the existing bucket elevators are prone to pile up materials in the lower section. At this time, the bucket will dig out the accumulated materials at the bottom when climbing, increasing the load of the motor. Once the material is fed too quickly, it will also cause blockage and jamming, causing equipment failure. Therefore, the existing bucket elevators need to manually cover the material in the lower section to reduce the load of the motor, which greatly affects the continuous operation of production.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 10 As shown, the present invention provides a high-efficiency bucket elevator, comprising a feeding device 1, a discharging device 2, a bucket 3, and a transmission belt 4.

[0030] The feeding device 1 is used to transport materials into the bucket elevator, the hopper 3 is used to transport materials, and the discharging device 2 is used to transport materials out of the bucket elevator. The discharging port 211 of the discharging device 2 is arranged on the right side of the transmission belt 4, the feeding port 121 of the feeding device 1 is arranged on the left side of the transmission belt 4, and the feeding device 1 is arranged below the discharging device 2.

[0031] The discharging device 2 is provided with a motor 5, the output shaft of the motor 5 is connected to a driving wheel 6, and a driven wheel 7 is provided in the feeding device 1. The transmission belt 4 is arranged in a loop and is mounted on the driving wheel 6 and the driven wheel 7. The transmission belt 4 can rotate under the action of the driving wheel 6. A plurality of hoppers 3 are installed on the transmission belt 4 and are driven by the transmission belt 4 to achieve lifting. Since the transmission belt 4 is arranged in a loop, when the hopper 3 runs to the top of the transmission belt 4, it will flip over and pour out the material in the hopper 3, so that the discharging device 2 can deliver the material.

[0032] Combine the following Figures 4 to 7 The structure of the feeding device 1 will be described.

[0033] refer to Figure 4 and Figure 5 The feeding device 1 includes a feeding section outer cover 11, a feeding hopper 12, a feeding guiding mechanism 13, and a feeding receiving mechanism 14.

[0034] The interior of the feed section outer cover 11 is a cavity for accommodating the transmission belt 4 , the hopper 3 and the driven wheel 7 .

[0035] The function of the feed hopper 12 is to feed materials, and a feed port 121 opening upward is provided outside the feed section cover 11. The feed hopper 12 is installed on the feed section cover 11 and is provided with a feed channel connecting the outside and the inside of the feed section cover 11. In this embodiment, the feed hopper 12 is located to the right of the transmission belt 4.

[0036] The material feeding and guiding mechanism 13 comprises a material guiding track 131 located in the material feeding section outer cover 11. The function of the material guiding track 131 is to recover the materials leaked from the two sides of the hopper 3.

[0037] The material feeding and receiving mechanism 14 is located below the feed hopper 12 .

[0038] refer to Figure 6 and Figure 7 The feeding and receiving mechanism 14 includes a receiving mechanism body 141. A receiving cavity 1411 is provided in the receiving mechanism body 141. The receiving mechanism body 141 is provided with a receiving mechanism feeding port 1412 communicating with the guide track 131 and a receiving mechanism discharging port 1413 communicating with the inside of the feeding section outer cover 11.

[0039] The material guide track 131 transports the material into the receiving chamber 1411 through the material receiving mechanism feed port 1412 and transports the material into the feeding section outer cover 11 through the material receiving mechanism discharge port 1413 , and the material finally enters the hopper 3 below.

[0040] Further, the feed hopper 12 is partially disposed in the feed section outer cover 11, the top of the receiving mechanism body 141 abuts against the bottom of the feed hopper 12, and the top of the receiving mechanism body 141 is configured as an inclined surface, which can guide the direction of the material being fed. Further, the side of the top surface of the receiving mechanism body 141 close to the hopper 3 is the bottom end.

[0041] Furthermore, the material feeding and receiving mechanism 14 further includes a material collecting portion 142 located in the receiving cavity 1411. The material collecting portion 142 connects the material collecting mechanism material feeding port 1412 and the material collecting mechanism material discharging port 1413. The material collecting mechanism material feeding port 1412 is located above the material collecting mechanism material discharging port 1413. The material collecting portion 142 can transport the material from the material collecting mechanism material feeding port 1412 to the material collecting mechanism material discharging port 1413.

[0042] Furthermore, there are two groups of feeding and guiding mechanisms 13. The two groups of feeding and guiding mechanisms 13 are respectively located at the front and rear sides of the hopper 3, that is, when the hopper 3 is raised or lowered, it passes between the two groups of feeding and guiding mechanisms 13. Such an arrangement can collect the materials falling from the front and rear sides of the hopper 3. There are two feeding ports 1412 of the collecting mechanism, and the guiding rails 131 correspond to the feeding ports 1412 of the collecting mechanism one by one. The collecting part 142 is connected to both feeding ports 1412 of the collecting mechanism.

[0043] Furthermore, the feeding and receiving mechanism 14 further includes a material guide bar 143, which is mounted on the receiving mechanism body 141 and can slide in the lateral direction to approach or move away from the receiving cavity 1411. The material guide bar 143 is at least partially disposed in the feeding section outer cover 11. The function of the material guide bar 143 is to fill the gap between the hopper 3 and the receiving mechanism body 141. The material falling from the top of the feeding hopper 12 and the receiving mechanism body 141 is received by the material guide bar 143 located in the feeding section outer cover 11, thereby preventing the material from falling from the gap between the hopper 3 and the receiving mechanism body 141.

[0044] Furthermore, the width of the portion of the guide strip 143 located in the feed section outer cover 11 is smaller than the width of the gap between the hopper 3 and the material receiving mechanism body 141. When the hopper 3 moves upward, the hopper 3 squeezes the guide strip 143, causing the guide strip 143 to move rightward, and the material on the guide strip 143 enters the hopper 3.

[0045] Furthermore, the guide strip 143 passes through the material receiving mechanism body 141 and is connected to a resilient member 144 at the receiving cavity 1411. A spring 145 is connected to the resilient member 144 and the inner wall of the receiving cavity 1411. The function of the spring 145 is to push the resilient member 144 to drive the guide strip 143 to return to the left.

[0046] Furthermore, a rebound slot 146 is provided in the receiving cavity 1411, and the bottom of the rebound member 144 is inserted in the rebound slot 146. The rebound slot 146 serves to limit the position, thereby preventing the rebound member 144 from being displaced too much when being driven to the right by the guide strip 143.

[0047] Furthermore, there are two guide bars 143, and the material collection portion 142 is located between the two guide bars 143. The lower guide bar 143 can also carry the material falling from the material receiving mechanism outlet 1413, preventing the material falling from the material receiving mechanism outlet 1413 from falling from the gap between the hopper 3 and the material receiving mechanism body 141.

[0048] Furthermore, the feeding device 1 further comprises two lower scraping mechanisms 15 disposed in the feeding section outer cover 11. The two lower scraping mechanisms 15 are respectively located at the front and rear sides of the hopper 3, that is, the interval between the two lower scraping mechanisms 15 is a passage through which the hopper 3 passes when it is lifted or lowered.

[0049] The lower scraping mechanism 15 includes a lower material receiving plate 151 and a lower scraping plate 152 disposed on the inner side of the lower material receiving plate 151. In this embodiment, the inner side of the lower material receiving plate 151 is defined as the side facing the hopper 3. A lower material receiving track 1511 is disposed on the lower material receiving plate 151, and the bottom end of the lower material receiving track 1511 is configured as an opening located above the feed hopper 12. The function of the lower scraping plate 152 is to scrape the materials on the front and rear sides of the rising hopper 3, and then the materials fall from the lower material receiving track 1511 into the feed hopper 12.

[0050] Furthermore, the lower scraping mechanism 15 also includes a conveying track 153 connected to the bottom opening of the lower material receiving track 1511 , and the conveying track 153 transports the material to the feed hopper 12 .

[0051] Combine the following Figure 8 and Fig. 9 The structure of the discharging device 2 is described in detail.

[0052] like Figure 8 and Fig. 9As shown, the discharging device 2 includes a discharging section outer cover 21, an upper material receiving mechanism 22, a first discharging bottom plate 23, and a second discharging bottom plate.

[0053] The discharge section outer cover 21 is provided with a discharge port 211, which is located on the left side of the transmission belt 4 and opens downward. The inside of the discharge section outer cover 21 is a cavity for the transmission belt 4 and the hopper 3 to pass through.

[0054] The upper material receiving mechanism 22, the first material discharging bottom plate 23, and the second material discharging bottom plate are all arranged in the material discharging section outer cover 21. The upper material receiving mechanism 22 includes two upper material receiving plates 221 and an upper scraper 222 installed on the inner side of the upper material receiving plates 221. A gap is arranged between the two upper material receiving plates 221, and the hopper 3 can pass through between the two upper material receiving plates 221 when descending. An upper material receiving track 2211 is arranged in the upper material receiving plate 221. The upper scraper 222 can scrape the materials on the front and rear sides of the hopper 3, and the scraped materials enter the upper material receiving track 2211 and fall along the upper material receiving track 2211.

[0055] The first discharging bottom plate 23 is tilted. The second discharging bottom plate is tilted and located below the first discharging bottom plate 23, and the discharging port 211 is located below the second discharging bottom plate.

[0056] The upper material receiving mechanism 22 is divided into two groups, one of which is disposed above the first material discharging bottom plate 23 , and the other of which is disposed between the second material discharging bottom plate and the first material discharging bottom plate 23 .

[0057] After the hopper 3 turns over on the top of the transmission belt 4, the material is poured onto the first discharge bottom plate 23. The upper receiving mechanism 22 above scrapes the material on both sides of the hopper 3 and transfers it to the first discharge bottom plate 23. Then the material slides from the first discharge bottom plate 23 to the second discharge bottom plate, and finally slides from the second discharge bottom plate to the discharge port 211. The upper receiving mechanism 22 below can transfer the material that has fallen into the first discharge bottom plate 23 in time to the second discharge bottom plate.

[0058] Furthermore, a first front scraper 231 is provided on the top of the first discharging bottom plate 23, and a second front scraper is provided on the top of the second discharging bottom plate. The first front scraper 231 can prevent the material from falling into the gap between the first discharging bottom plate 23 and the hopper 3, and the second front scraper can prevent the material from falling into the gap between the second discharging bottom plate and the hopper 3.

[0059] The feeding device 1 and the discharging device 2 are connected via a plurality of intermediate sections 8. Fig.10As shown, the middle section 8 is a cylinder with upper and lower openings, and the transmission belt 4 and the hopper 3 pass through the middle section 8. Two limit plates 81 are provided on at least one middle section 8. The two limit plates 81 are located between the left and right parts of the transmission belt 4, and a gap is provided between the two limit plates 81. The limit plates 81 can prevent the left and right parts of the transmission belt 4 from colliding during operation.
