Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting machine for lowering grain pits. Background Technology
[0002] Grain pits are important facilities used for receiving, screening and storing raw grains during grain processing and storage. Grain pits are usually designed in the shape of a sloping bucket with a right-angled triangle cross-section. To ensure operational safety, iron railings are usually installed above the grain pits to prevent people from accidentally entering or falling in.
[0003] In this system, the bottom of the grain pit needs to be connected to the feed hopper of the elevator. The grain in the grain pit is transported to the processing system by the bucket elevator. The grain enters the outer shell of the elevator, and the reciprocating bucket is used to lift the grain. Some grain will continue to accumulate in the outer shell of the elevator. Since the bottom of the elevator is installed in the grain pit, the grain accumulated at the bottom of the elevator is not easy to be discharged. Long-term accumulation can easily cause mold. Therefore, we propose an elevator for the grain pit. Utility Model Content

[0034] In this embodiment, as Figure 1 and Figure 2As shown, a hoist for a grain pit includes a hoist body 1. An anti-accumulation component 2 is installed at the bottom of the hoist body 1. The anti-accumulation component 2 is used to discharge the material deposited at the bottom of the hoist body 1. The anti-accumulation component 2 includes a collection hopper 21, a discharge shell 22, bolts 23, a pusher plate 24, a hydraulic rod 25, a connector 26, and a sealing plate 27. The collection hopper 21 is connected to the bottom of the hoist body 1. The discharge shell 22 is connected to the collection hopper 21 by bolts 23. The pusher plate 24 is inserted into the cavity of the discharge shell 22. The output end of the hydraulic rod 25 is fixedly connected to the pusher plate 24. The hydraulic rod 25 is connected to the discharge shell 22 by the connector 26. The sealing plate 27 is fixedly connected to the top end of the pusher plate 24. When the pusher plate 24 pushes material, the sealing plate 27 can close the feed port of the discharge shell 22.
[0035] Therefore, bolts 23 are used to connect the discharge shell 22 and the collection hopper 21, and connectors 26 are used to fix the position of the hydraulic rod 25. When cleaning the grain deposited at the bottom of the elevator body 1, the hydraulic rod 25 is activated. When the output end of the hydraulic rod 25 retracts, it drives the pusher plate 24 and the sealing plate 27 to move. After the sealing plate 27 separates from the feed port of the discharge shell 22, the deposited grain enters the discharge shell 22. The output end of the hydraulic rod 25 is extended, and the pusher plate 24 pushes the grain in the discharge shell 22. At the same time, the sealing plate 27 seals the feed port of the discharge shell 22. The grain deposited in the elevator body 1 is guided into the discharge shell 22 through the collection hopper 21, and the grain in the discharge shell 22 is discharged by the pusher plate 24 to prevent the grain from accumulating at the bottom of the elevator body 1 and causing mold due to inconvenience in cleaning.
[0036] Furthermore, the collecting hopper 21 connects the bottom of the elevator body 1 and the discharge shell 22. The top of the discharge shell 22 is machined with a feeding port, and the end of the discharge shell 22 away from the hydraulic rod 25 is provided with a discharge port. The discharge shell 22 is machined with a cavity that matches the pusher plate 24. The pusher plate 24 and the sealing plate 27 are arranged vertically.
[0037] In some embodiments, such as Figure 1 and Figure 5 As shown, the discharge end of the discharge shell 22 is equipped with an opening and closing assembly 3. The opening and closing assembly 3 is used to control the opening and closing of the discharge shell 22. The opening and closing assembly 3 includes a card seat 31, a rotating shaft 32, a bracket 33, an end cover 34, a cam 35, and a reset component 36. The bottom end of the card seat 31 is fixedly connected to the discharge shell 22. The bracket 33 is hinged to the card seat 31 through the rotating shaft 32. The top end of the end cover 34 is fixedly connected to the bracket 33. The end cover 34 is parallel to the discharge port of the discharge shell 22. The cam 35 is distributed at both ends of the rotating shaft 32. The reset component 36 is used to push the cam 35 to reset.
[0038] Furthermore, the card holder 31 is located on top of the discharge shell 22, the bracket 33 and the rotating shaft 32 are fixedly connected, the rotating shaft 32 is connected to the card holder 31 through the bearing, there are two cams 35, and the end cover 34 is used to close the discharge port of the discharge shell 22. The end cover 34 is designed to open and close, which facilitates the discharge of grain from the discharge shell 22.
[0039] In some embodiments, such as Figure 4 As shown, the reset component 36 includes a limiting shell 361, a T-shaped top plate 362, and an elastic element 363. The bottom end of the limiting shell 361 is fixedly connected to the discharge shell 22. The T-shaped top plate 362 is inserted into the slide groove of the limiting shell 361. One end of the T-shaped top plate 362 abuts against the cam 35. The other end of the T-shaped top plate 362 is fixedly connected to the elastic element 363. The elastic element 363 is embedded in the slide groove at the top of the limiting shell 361.
[0040] Furthermore, the top of the limiting shell 361 is machined with a sliding groove, the T-shaped top plate 362 is used to push the cam 35 to reset, and the two ends of the elastic element 363 are respectively connected to the T-shaped top plate 362 and the limiting shell 361.
[0041] In some embodiments, such as Figure 3 As shown, the connector 26 includes a clamp 261 and a positioning pin 262. The clamp 261 is fixedly connected to the hydraulic rod 25, and the clamp 261 is connected to the discharge shell 22 through the positioning pin 262.
[0042] Furthermore, clamp 261 is used to fix the tail end of hydraulic rod 25, and the outer wall of positioning pin 262 is threaded. Positioning pin 262 is used to connect discharge shell 22 and clamp 261.
[0043] In some embodiments, such as Figure 1 As shown, a support base 221 is fixedly connected to the bottom of the discharge shell 22, and a reinforcing rib 222 is fixedly connected to the support base 221.
[0044] Furthermore, the support base 221 supports the overall mechanism, and the use of reinforcing ribs 222 enhances the support capacity of the support base 221 for the discharge shell 22.
[0045] In some embodiments, such as Figure 1 As shown, the elevator body 1 includes a feed hopper 11, and a leak-proof plate 12 is fixedly connected to the feed inlet of the feed hopper 11. The leak-proof plate 12 is used to increase the contact area between the feed hopper 11 and the grain pit.
[0046] Furthermore, the grain in the lower grain pit enters the elevator body 1 through the feed hopper 11. The anti-leakage plate 12 widens the edge of the feed hopper 11 to prevent the grain from leaking between the feed hopper 11 and the lower grain pit.
[0047] In some embodiments, such as Figure 3 As shown, a rubber gasket is provided on the top of the sealing plate 27, which is used to increase the sealing between the sealing plate 27 and the discharge shell 22.
[0048] Furthermore, the rubber pad moves together with the sealing plate 27, increasing the sealing between the sealing plate 27 and the discharge shell 22, and preventing grain from getting stuck in the gap between the sealing plate 27 and the discharge shell 22.
[0049] In some embodiments, such as Figure 5 As shown, a counterweight plate 341 is fixedly connected to the side of the end cover 34 away from the discharge shell 22. The counterweight plate 341 lowers the center of gravity of the end cover 34.
[0050] Furthermore, the design of the counterweight plate 341 lowers the center of gravity of the end cap 34, which is beneficial for the end cap 34 to reset.
[0051] In some embodiments, such as Figure 4 As shown, the T-shaped top plate 362 includes a snap-fit plate 362a, which is inserted into the limiting groove of the limiting shell 361.
[0052] Furthermore, the design of the snap-fit plate 362a allows the T-shaped top plate 362 to move laterally within the limiting shell 361.
[0053] In some embodiments, such as Figure 4 As shown, elastic element 363 is a compression spring.
[0054] Furthermore, the elastic element 363 adopts a compression spring design, which facilitates the T-shaped top plate 362 to be reset in the limiting shell 361.
[0055] The working principle of this application is illustrated below with a preferred embodiment:
[0056] The elevator body 1 is installed in the grain pit. The feed hopper 11 on the elevator body 1 is connected to the discharge port of the grain pit. Grain enters the elevator body 1 through the feed hopper 11 for lifting. When it is necessary to discharge the grain deposited at the bottom of the elevator body 1, the hydraulic rod 25 is activated. The output end of the hydraulic rod 25 retracts, driving the pusher plate 24 to move. The pusher plate 24 drives the sealing plate 27 to separate from the feed port of the discharge shell 22. At this time, the grain at the bottom of the elevator body 1 enters the discharge shell 22 through the collection hopper 21. Then, the output end of the hydraulic rod 25 is extended, driving the pusher plate 24 to move. The pusher plate 24 pushes the grain towards the discharge end of the discharge shell 22. The sealing plate 27 located at the top of the pusher plate 24 seals the feed port of the discharge shell 22. As the output end of the hydraulic rod 25 extends, the grain in the discharge shell 22 pushes the end cover 34 to separate from the discharge shell 22, and then the grain is discharged. The end cover 34 drives the rotating shaft 32 and the cam 35 to rotate together. When the cam 35 rotates, it pushes the T-shaped top plate 362 to move inward along the slide groove of the limiting shell 361 to compress the elastic element 363. After the grain is discharged, the end cover 34 is in a vertical state under the action of the counterweight plate 341, and under the action of the elastic potential energy of the elastic element 363, it pushes the T-shaped top plate 362 and the cam 35 to reset, so that the end cover 34 and the discharge end of the discharge shell 22 fit together.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
