Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste material recycling and processing technology, and in particular to a hopper for recycling solid waste material and unloading it by gravity. Background Technology
[0002] Most of the leftover materials generated during the production process can be recycled and reused, but they need to be stored separately. Taking the recycling of waste materials generated from steel mill production and processing as an example, the hoppers are generally complete boxes or funnels. During loading, there is often tilting or slanting, which is not allowed in production operation standards; or a high lifting height is required. If the site conditions are not met, safety accidents can easily occur. In addition, when unloading materials from complete boxes or funnels, the waste hopper needs to be tilted. During tilting and unloading, the center of gravity of the waste hopper is unstable and the force is unbalanced, making it very easy for it to swing in the air. Due to the large size and weight of the waste hopper, objects may fall during the swing, posing a risk of injuring workers or damaging equipment, which is a significant safety hazard.
[0003] Therefore, it is necessary to develop a hopper for solid waste recycling and gravity unloading to overcome the above-mentioned technical problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a hopper for solid waste recycling and gravity unloading, which effectively overcomes the defects of the prior art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A hopper for solid waste recycling and gravity unloading includes two hopper bodies. The two hopper bodies are open at their close ends and upper parts. The upper parts of the two close ends of the two hopper bodies are hinged. A first lifting point is provided on each side of the two close ends of the two hopper bodies near the hinge point. The two first lifting points on the same side are distributed at both ends of the hinge point. A second lifting point is provided in the middle area of the upper part of the two far ends of the two hopper bodies. Locking components that can be opened or locked are provided on both sides of the close ends of the two hopper bodies.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, on either side of the upper part of the two bucket bodies that are close to each other, there is a first ear plate and two parallel second ear plates respectively. The first ear plate extends between the two second ear plates and is hinged by a pin that passes vertically through the three. The first lifting point is distributed on the first ear plate and the second ear plate and is symmetrically distributed at both ends of the pin.
[0009] Furthermore, all of the first lifting points are lifting holes.
[0010] Furthermore, a lifting rod is vertically fixed between the upper parts of the two buckets that are close to each other, and the lifting rod constitutes the first lifting point.
[0011] Furthermore, a limiting block is provided between the two second ear plates, and the two buckets can be flipped open around the pin until the upper edge of the first ear plate abuts against the limiting block.
[0012] Furthermore, the opening and closing angle of the two buckets is α, and 120°≤α≤150°.
[0013] Furthermore, a first reinforcing plate is fixed to the outer side of the upper edge of each of the two buckets along their respective edge lines. A second lifting point is provided at the upper middle area of the two buckets at the ends that are far apart from each other, at the first reinforcing plate. The second lifting point is a hole that passes through the first reinforcing plate and the upper edge of the bucket.
[0014] further,
[0015] Furthermore, a second reinforcing plate is fixed to the outer side of each of the two bucket bodies at one end close to each other, along their respective edge lines.
[0016] Furthermore, the buckets are all rectangular trough-shaped components, and steel corner protectors are fixed at the lower right angles of the two ends that are far apart from each other.
[0017] The advantages of this utility model are: the structure is simple and reasonable, it can realize the collection and recycling of surplus materials and the large-angle opening and unloading under gravity, and the operation process is relatively safe. Attached Figure Description

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0028] Example
[0029] like Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, the hopper for solid waste recycling and gravity unloading in this embodiment includes two hopper bodies 1. The two hopper bodies 1 are open at their respective ends and upper parts. The upper parts of the two sides of the ends of the two hopper bodies 1 that are close to each other are hinged. The two sides of the ends of the two hopper bodies 1 that are close to each other are respectively provided with first lifting points 11 near the hinge points. The two first lifting points 11 on the same side are distributed at both ends of the hinge points. The middle area of the upper part of the ends of the two hopper bodies 1 that are far apart from each other is provided with second lifting points 12.
[0030] In this embodiment, the hopper for solid waste recycling and gravity unloading is used for static storage of waste materials. Two hopper bodies 1 are placed on the ground or other carrier surface. Under gravity, the two hopper bodies 1 close together to form a complete hopper, storing the material inside. Then, a crane is used to lift the hopper using the first lifting point 11. Before lifting, the lifting ropes are anchored at the first lifting points 11 on both sides. Since the first lifting points 11 are located at both ends of the hinge joint of the two hopper bodies 1 on both sides of the hopper, the lifting ropes (represented by A in the figure) apply an oblique force to the hopper body 1. The force has an upward vertical component and a horizontal component pointing towards the other bucket 1, which effectively closes the two buckets 1, preventing them from separating during lifting. This allows them to be transferred to the target location. During unloading, the crane's lifting rope is anchored to the second lifting point 12 at the ends of the two buckets 1 that are furthest apart. After lifting, the two buckets 1 will tilt downwards at their middle (the ends closest to each other) under gravity, causing them to swing open to a larger angle, allowing the remaining material inside the buckets to fall smoothly. Furthermore, the entire unloading process does not require tilting the buckets; after lifting, gravity allows the two buckets 1 to flip and open to a larger angle. The structural design is simple and reasonable, and the operation is relatively safe.
[0031] In this embodiment, on either side of the upper part of the two bucket bodies 1 that are close to each other, there are corresponding first ear plates 111 and two parallel second ear plates 112. The first ear plate 111 extends between the two second ear plates 112 and is hinged by a pin (represented by b in the figure) that passes vertically through all three. The first lifting points 11 are distributed on the first ear plate 111 and the second ear plate 112, and are symmetrically distributed at both ends of the pin. Each bucket body 1 has a first ear plate 111 and a second ear plate 112 distributed on both sides. The two bucket bodies 1 have roughly the same structural shape and a relatively stable center of gravity. Furthermore, by using the method of interlocking and pinning the first ear plate 111 with the two second ear plates 112, the structural design is relatively compact and less prone to tilting or swaying.
[0032] In this embodiment, the first lifting point 11 is a lifting hole. Specifically, the lifting hole passes through the first ear plate 111 or through two second ear plates 112. The end of the lifting rope can be equipped with a hook, which passes through the lifting hole when lifting.
[0033] As a preferred implementation method, such as Figure 4 As shown, a hanging rod is vertically fixed between the upper parts of the two bucket bodies 1 that are close to each other, and the hanging rod constitutes the first lifting point 11.
[0034] In the above implementation scheme, the first lifting point 11 adopts the form of a lifting rod, which makes the connection structure between the two buckets 1 more robust and the arrangement of the lifting ropes simpler.
[0035] In a preferred embodiment, a limiting block 13 is provided between the two second ear plates 112, and the two bucket bodies 1 can be flipped open around the pin until the upper edge of the first ear plate 111 abuts against the limiting block 13.
[0036] In the above implementation scheme, due to the design of the limiting block 13, the maximum angle that the two buckets 1 can open is limited, avoiding the situation where the hinge point of the buckets 1 moves up and down during unloading if there is no angle limit, thus avoiding the situation where the opening of the buckets 1 is unstable.
[0037] In this embodiment, the opening angle of the two buckets 1 is α, and 120°≤α≤150°. This angle design is reasonable, making unloading more convenient and faster.
[0038] In a preferred embodiment, a first reinforcing plate 14 is fixed to the outer side of the upper edge of each of the two bucket bodies 1 along their respective edge lines. A second lifting point 12 is provided at the upper middle area of the two bucket bodies 1 at the opposite ends of each other, at the first reinforcing plate 14. The locking assembly 2 includes a U-shaped socket 21 rotatably mounted on the side end of one of the bucket bodies 1 and an insert plate 22 rotatably mounted on the side end of the other bucket body 1. The insert plate 22 is inserted into the socket 21 and locked by a pin 23 passing through both.
[0039] In the above implementation scheme, the design of the first reinforcing plate 14 increases the structural strength of the upper edge of the bucket body 1, thereby making the location of the second lifting point 12 more robust and preventing breakage or deformation of the stress point (second lifting point 12) after prolonged use. Simultaneously, the hook at the end of the lifting rope can be easily attached by passing it through the hole.
[0040] In a preferred embodiment, the locking assembly 2 includes a U-shaped socket 21 rotatably mounted on one side of one of the bucket bodies 1 and a plug plate 22 rotatably mounted on the other side of the bucket body 1. The plug plate 22 is inserted into the socket 21 and locked by a pin 23 passing through both.
[0041] In the above implementation scheme, before loading, the hopper is placed on the ground or other carrier in a closed state. The insert plates 22 on both sides of the two hoppers 1 that are close to each other are rotated into the sockets 21 on the corresponding sides and then locked by the pins 23. This can further ensure that the two hoppers 1 will not open due to external interference in the closed state. When unloading the remaining material, the pins 23 are pulled out, and the sockets 21 and insert plates 22 hang down naturally under the action of gravity.
[0042] In this embodiment, a first rotating shaft is connected to the side end of the closed end of the socket 21. The first rotating shaft is rotatably assembled with the corresponding part of the bucket body 1. A second rotating shaft is connected to the side end of one end of the plug plate 22. The second rotating shaft is rotatably assembled with the corresponding part of the bucket body 1.
[0043] In this embodiment, a second reinforcing plate 15 is fixed to the outer side of the two bucket bodies 1 at their respective adjacent ends along their respective edge lines. The design of the second reinforcing plate 15 improves the structural strength of the edge structure at the adjacent ends of the two bucket bodies 1, preventing damage during repeated opening and closing collisions.
[0044] In this embodiment, the bucket bodies 1 are all rectangular trough-shaped components, and steel corner protectors 16 are fixed to the lower right angles of the two ends that are far apart from each other. The design of the steel corner protectors 16 can effectively protect the right angle parts of the lower part of the bucket body 1 that are easy to come into contact with the ground or other carriers, reduce wear, and extend service life.
