Abstract
Description
Technical Field
[0001] This utility model relates to the field of unloading technology, and specifically to a storage bin that facilitates automatic unloading. Background Technology
[0002] In the process of recycling waste plastics, the waste plastics are crushed into loose materials and fragments. Storage silos are often used to temporarily store these materials. When unloading these loose materials and fragments, the silos generally adopt a tipping structure, which tilts the entire silo over. Under the action of gravity, the materials slide out of the silo. Such a structure requires a lifting mechanism with a large single output force, resulting in high overall cost and complex structure. When the silo is large, the lifting height during unloading is also high, which places high demands on the height of the plant. Moreover, the unloading process is large and dangerous. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a storage bin that facilitates automatic unloading, thereby solving the problem that the tilting bucket type unloading bin has a complex structure and is too high and dangerous when unloading and lifting.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A storage bin for facilitating automatic unloading includes a box for loading materials. A discharge door is located on one side of the box for unloading materials. A discharge plate is located on the bottom surface of the inner cavity of the box. The side of the discharge plate away from the discharge door extends upward along the inner wall of the box. The discharge plate is sequentially divided into multiple neatly arranged discharge plate strips perpendicular to the unloading direction. Multiple parallel discharge plate strips are combined to form a complete discharge plate. Multiple sequentially arranged horizontal push cylinders are located on the side wall of the box away from the discharge door. The extended sides of the multiple discharge plate strips correspond one-to-one with and are connected to the horizontal push cylinders. Driven by the corresponding horizontal push cylinders, any discharge plate strip can extend or retract individually. During unloading, each horizontal push cylinder pushes multiple discharge plate strips to extend simultaneously, carrying the material out of the box. Then, the multiple discharge plate strips retract sequentially at intervals, causing the material to fall into the empty space formed by the first retracted discharge plate strip.
[0006] As a preferred embodiment, the side shape of the unloading plate slits is "L" shaped, including a horizontal bottom plate and vertical side plates, and the bottom of the bottom plate and the contact surface of the box body are translated by sliding friction.
[0007] In a preferred embodiment, the cylinder body of the push cylinder is fixed to the outer side of the housing and near the bottom. The telescopic rod of any push cylinder is inserted into the housing and fixedly connected to the corresponding side plate near the bottom. A sliding rod is also provided above the push cylinder. Multiple parallel sliding rods correspond one-to-one with the side plates. One end of any sliding rod passes through the side wall of the housing and is fixed to the corresponding side plate. Multiple sliding sleeves are provided on the side wall of the housing near the top. The sliding rods are respectively fitted into the sliding sleeves. The length of the sliding rod is not less than the stroke of the push cylinder.
[0008] As a preferred embodiment, the top two sides of the unloading gate are hinged to the box body, and a top door cylinder is inclinedly arranged on the side of the box body near the unloading gate. One end of the cylinder body of the top door cylinder is hinged to the side of the box body near the bottom, and the middle of the side edge of the unloading gate is hinged to one end of the telescopic rod of the top door cylinder.
[0009] As a preferred embodiment, the bottom of the box is provided with multiple support legs, which can be fixed to the ground.
[0010] In a preferred embodiment, the width of the unloading plate slits perpendicular to the unloading movement direction is 5-15cm.
[0011] The beneficial effects of this utility model are as follows: Inside the container used for loading materials, unloading plates are provided along the bottom surface and the innermost side surface of the container. Materials accumulate on the unloading plates, which are composed of multiple unloading plate strips. Multiple horizontal push cylinders are each positioned opposite one of the unloading plate strips. The unloading plate strips are driven by their respective horizontal push cylinders to extend and retract independently. During unloading, each horizontal push cylinder simultaneously pushes each unloading plate strip out of the container. Then, each unloading plate strip retracts sequentially at intervals, causing the material to fall at the first retracted unloading plate strip. After the material falls, all the remaining unloading plate strips retract. In this way, the material is first moved horizontally out of the container before falling for unloading. Unloading can be achieved without a lifting mechanism, avoiding the safety hazards caused by lifting unloading. It is also particularly suitable for crushed, bulk, and powdered materials. Multiple horizontal push cylinders distribute the thrust, eliminating the need for high-power power components, thus easily achieving the unloading process. The overall structure is simple, occupies little space, is highly practical, and is easy to operate and maintain. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0017] The storage bin described in this utility model facilitates automatic unloading. See also... Figures 1-2 As shown, the device includes a container 1 for loading materials. A discharge door 10 for unloading materials is provided on one side of the container 1. A discharge plate 2 is provided on the bottom surface of the inner cavity of the container 1. The discharge plate 2 extends upward along the inner wall of the container 1 on the side away from the discharge door 10. The discharge plate 2 is sequentially divided into multiple neatly arranged discharge plate strips 21 perpendicular to the unloading direction. Multiple parallel and closely spaced discharge plate strips 21 are combined to form the discharge plate 2 as a whole. The side wall of the container 1 away from the discharge door 10... Multiple horizontal push cylinders 6 are arranged in sequence. The extended sides of multiple unloading plate strips 21 correspond to and are connected to the horizontal push cylinders 6 one by one. Under the drive of the corresponding horizontal push cylinders 6, any unloading plate strip 21 can extend or retract individually. During unloading, each horizontal push cylinder 6 pushes multiple unloading plate strips 21 to extend simultaneously, driving the material out of the box 1. Then, multiple unloading plate strips 21 retract in sequence at intervals, so that the material falls into the empty space formed by the first retracted unloading plate strip 21.
[0018] Specifically, a discharge plate 2 is added to the bottom surface inside the housing 1. During loading, the material accumulates on top of the discharge plate 2. When discharging, the discharge door 10 is opened, and then the hydraulic cylinder 6 pushes the discharge plate 2 outwards. The material on top of the discharge plate 2 moves accordingly. The upward-extending side of the discharge plate 2 pushes the innermost material outwards. The overall bent shape of the discharge plate 2, like a sieve, carries the material outwards. After the discharge plate 2 carries the material out of the discharge door 10, the individual, non-adjacent discharge plate strips 21 are retracted at intervals. During the initial retraction of the discharge plate strips 21, since their adjacent strips 21 are not... Because the unretracted discharge plate slats 21 extend upwards, forming side plates 3 that block the material, reducing the amount of material carried back by the first retracted discharge plate slats 21. This keeps the material on the outside of the box 1, allowing it to fall through the gaps created by the retracted discharge plate slats 21. Since the discharge plate slats 21 are narrow, most of the material falls off as they retract one after another, leaving very little material residue on the unretracted discharge plate slats 21. Furthermore, due to vibrations during movement, the material falls off relatively cleanly. Finally, all the discharge plate slats 21 retract, completing the unloading process.
[0019] In this embodiment, the side shape of the unloading plate slats 21 is "L" shaped, including a horizontal base plate 9 and a vertical side plate 3. The bottom of the base plate 9 and the contact surface with the box body 1 are translated by sliding friction. The contact surface between the steel unloading plate slats 21 and the box body 1 becomes smoother with wear. The smooth steel surface has low resistance, making it easier to push the material out of the unloading plate 2 and realize material unloading.
[0020] like Figure 1 and Figure 2 The cylinder body of the push cylinder 6 is fixed on the outer side of the housing 1 and near the bottom. The telescopic rod of any push cylinder 6 is inserted into the housing 1 and fixedly connected to the corresponding side plate 3 near the bottom. A sliding rod 4 is also provided above the push cylinder 6. Multiple parallel sliding rods 4 correspond one-to-one with the side plates 3. One end of any sliding rod 4 passes through the side wall of the housing 1 and is fixed on the corresponding side plate 3. Multiple sliding sleeves 5 are provided on the side wall of the housing 1 near the top. The sliding rods 4 are respectively fitted into the sliding sleeves 5. The length of the sliding rod 4 is not less than the stroke of the push cylinder 6. When unloading material, the unloading plate 2 gradually moves the material out of the box 1, causing the center of gravity to shift continuously. To maintain stability, the side plate 3 of the unloading plate 2 is connected to the slide rod 4 near the top. The slide rod 4 slides in the sliding sleeve 5 fixed on the box 1. This not only allows the unloading plate slits 21 to move in a straight line, stabilizing the extension and retraction directions, but also prevents the unloading plate 2 from overturning due to the shift in the center of gravity when it carries the material outward.
[0021] In this embodiment, the top two sides of the unloading gate 10 are hinged to the housing 1. A top door cylinder 8 is inclinedly arranged on the side of the housing 1 near the unloading gate 10. One end of the cylinder body of the top door cylinder 8 is hinged to the side of the housing 1 near the bottom. The middle of the side edge of the unloading gate 10 is hinged to one end of the telescopic rod of the top door cylinder 8. In actual operation, the unloading gate 10 can open and close automatically, reducing the danger of personnel contact.
[0022] In this embodiment, the bottom of the housing 1 is provided with multiple support legs 7, which can be fixed to the ground during operation. The support legs 7 are fixed to the ground with bolts, making the housing 1 stable and preventing it from tipping over due to gravity shift during unloading.
[0023] In this embodiment, the width of the unloading plate slits 21 perpendicular to the unloading movement direction is 5-15cm. The width of the unloading plate slits 21 should not be too wide or too narrow. If it is too wide, the material will easily fall out and not be completely cleaned up. If it is too narrow, the unloading plate slits 21 will not be strong enough and will easily bend.
[0024] The working process of this utility model is as follows:
[0025] As shown in Figure 1-2, firstly, the box 1 is filled with materials, such as recycled waste plastic fragments or granules. The unloading door 10 is in the closed state, and the unloading plate 2 is in the retracted state. The materials accumulate on the horizontal bottom plate 9 of the unloading plate 2. When unloading, the top door cylinder 8 lifts the unloading door 10, and the unloading door 10 flips upward. Multiple horizontal push cylinders 6 simultaneously push each unloading plate 2 to extend. When the materials are sent out of the box 1, they start to fall from the unobstructed edge. After all the unloading plates 2 have extended, the adjacent unloading plate strips 21 are retracted simultaneously. The materials almost all fall into the gaps formed by the retracted unloading plate strips 21. Finally, the remaining unloading plate strips 21 are also retracted at the same time, and the unloading door 10 falls down, completing the unloading process.
[0026] The above embodiments are merely illustrative of the principles and effects of this utility model, as well as some of its applications, and are not intended to limit this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
