Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, and more specifically, to a material storage bin. Background Art

[0002] Silos are equipment used to store or distribute various raw materials and finished products in powder, granular, liquid or gaseous form. Usually, they consist of a silo, a silo door and a filler or drum-shaped body, which can be used to store and distribute materials during the production process.

[0003] A feed pipe is provided on the outer wall of some existing storage silos. The feed pipe is used to connect to the material transmission system. The material transmission system includes a pipeline, a funnel and a fan, wherein the two ends of the pipeline are respectively connected to the fan and the feed pipe, and the funnel is connected to the pipeline. People add granular materials into the funnel so that the granular materials enter the pipeline. Under the action of the fan, the granular materials enter the storage silo along the pipeline through the feed pipe. In this way, it is convenient for people to add granular materials into the storage silo.

[0004] After the material is transferred, people need to disassemble the pipeline and the feed pipe. In order to facilitate the disassembly of the pipeline and the feed pipe, one end of the existing pipeline connected to the feed pipe has a certain deformation ability. People put the pipeline on the feed pipe to ensure the sealing between the two, and also facilitate the disassembly of the pipeline and the feed pipe. After disassembling the pipeline and the feed pipe, people need to seal one end of the feed pipe, which can prevent external dust, moisture or other contaminants from entering the storage bin, thereby ensuring the quality and purity of the material in the storage bin. The existing method is generally to fix the cover on the feed pipe with screws, which makes the process of sealing the feed pipe more troublesome.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a storage bin.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a storage bin, comprising a bin body and a feed pipe arranged on the outer wall of the bin body, the feed pipe is sleeved with a sliding sleeve, the sliding sleeve slides along the length direction of the feed pipe, the lower end of the sliding sleeve is rotatably connected with a flip cover, an elastic member is arranged between the flip cover and the sliding sleeve, the elastic member always provides the flip cover with a force to rotate toward the sliding sleeve, the lower side of the sliding sleeve is provided with a sealing ring 1 for contacting with the flip cover, the outer peripheral wall of the feed pipe is provided with a sealing ring 2, the sealing ring 2 is used to seal the gap between the sliding sleeve and the feed pipe.

[0008] The utility model is further configured as follows: two fixed blocks are fixedly connected to the outer peripheral wall of the sliding sleeve, a rotating shaft is arranged between the two fixed blocks, the flip cover is fixedly connected to the rotating shaft, the elastic member is a torsion spring sleeved on the rotating shaft, and the two ends of the torsion spring are respectively clamped on the fixed block and the flip cover.

[0009] The utility model is further configured as follows: the lower side of the second sealing ring is flush with the lower side of the feed pipe, and the thickness of the second sealing ring is thinner as it is closer to the upper and lower sides thereof.

[0010] The utility model is further configured as follows: an annular groove is provided on the outer peripheral wall of the feed pipe, and a buckle head for buckling into the annular groove is fixedly connected to one end of the flip cover facing away from the fixing block.

[0011] The utility model is further configured as follows: the buckle head is configured in a hemispherical shape.

[0012] The utility model is further configured as follows: a friction portion which is always located above the sliding sleeve is arranged on the feeding pipe, and a plurality of friction lines are arranged on the outer peripheral wall of the sliding sleeve.

[0013] In summary, the utility model has the following beneficial effects: after people separate the pipeline from the feed pipe, they move the sliding sleeve downward until the lower end of the sliding sleeve is located at the lower end of the feed pipe. At this time, the flap will maintain a close contact with the sealing ring 1 under the action of the elastic member, thereby ensuring the sealing between the flap and the sliding sleeve, and the sealing ring 2 will be stuck between the sliding sleeve and the feed pipe, thereby ensuring the sealing between the sliding sleeve and the feed pipe. When people need to connect the feed pipe and the pipeline, they slide the sliding sleeve upward. At this time, the feed pipe will push the flap open, so that the flap flips back to the direction of the feed pipe. At this time, the lower end of the feed pipe will be exposed, and people will set the pipeline sleeve at the lower end of the feed pipe to achieve the connection between the two. This arrangement makes it possible to close and open the feed pipe by simple sliding, which is convenient for people to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Storage silos, such as Figure 1 and Figure 2 As shown, it includes a warehouse body 1 and a feeding pipe 2 arranged on the outer wall of the warehouse body 1, a sliding sleeve 3 is sleeved on the feeding pipe 2, the sliding sleeve 3 slides along the length direction of the feeding pipe 2, the lower end of the sliding sleeve 3 is rotatably connected with a flip cover 4, an elastic member is arranged between the flip cover 4 and the sliding sleeve 3, the elastic member always provides the flip cover 4 with a force to rotate in the direction of the sliding sleeve 3, a sealing ring 1 5 for contacting with the flip cover 4 is arranged on the lower side of the sliding sleeve 3, a sealing ring 2 6 is arranged on the outer peripheral wall of the feeding pipe 2, the sealing ring 2 6 is used to block the gap between the sliding sleeve 3 and the feeding pipe 2, after people separate the pipeline from the feeding pipe 2, people move the sliding sleeve 3 downward until the lower end of the sliding sleeve 3 is located at the feeding pipe 2. At the lower end, the flip cover 4 will maintain a close contact with the sealing ring 1 5 under the action of the elastic member, thereby ensuring the sealing between the flip cover 4 and the sliding sleeve 3, and the sealing ring 2 6 will be stuck between the sliding sleeve 3 and the feeding pipe 2, thereby ensuring the sealing between the sliding sleeve 3 and the feeding pipe 2. When people need to connect the feeding pipe 2 and the pipeline, they slide the sliding sleeve 3 upwards. At this time, the feeding pipe 2 will push the flip cover 4 open, so that the flip cover 4 flips back to the feeding pipe 2. At this time, the lower end of the feeding pipe 2 will be exposed, and people will set the pipeline sleeve at the lower end of the feeding pipe 2 to connect the two. This arrangement makes it possible to close and open the feeding pipe 2 by simple sliding, which is convenient for people to operate.

[0020] like Figure 2 and Figure 3 As shown, two fixing blocks 7 are fixedly connected to the outer peripheral wall of the sliding sleeve 3, and through holes are opened on the two fixing blocks 7. A rotating shaft 8 is arranged between the two fixing blocks 7, and the two ends of the rotating shaft 8 are respectively inserted into the two through holes. The flip cover 4 is fixedly connected to the rotating shaft 8, and the flip cover 4 rotates around the center line of the rotating shaft 8. The elastic member is a torsion spring sleeved on the rotating shaft 8, and the two ends of the torsion spring are respectively clamped on the fixing block 7 and the flip cover 4. When one side of the flip cover 4 contacts the lower side of the sliding sleeve 3, the torsion spring is still in a compressed state. This arrangement can ensure that the flip cover 4 and the sliding sleeve 3 are in contact. The resistance force between the sealing ring 1 5 ensures the sealing effect between the flip cover 4 and the lower end of the sliding sleeve 3. The lower side of the sealing ring 2 6 is flush with the lower side of the feed pipe 2. This arrangement ensures that as long as the sliding sleeve 3 slides upward for a certain distance, the sliding sleeve 3 will not contact the sealing ring 2 6, thereby making the subsequent sliding upward process of the sliding sleeve 3 less labor-intensive. The thickness of the sealing ring 2 6 is thinner as it approaches its upper and lower sides, thereby forming guiding inclined surfaces on the upper and lower ends of the sealing ring 2 6, so that whether the pipeline is set on the feed pipe 2 or the sliding sleeve 3 slides downward, it will be smoother.

[0021] like Figure 2As shown, an annular groove 9 is provided on the outer peripheral wall of the feed pipe 2, and the annular groove 9 is located above the sealing ring 2 6. A buckle head 10 for buckling into the annular groove 9 is fixedly connected to the end of the flip cover 4 facing away from the fixed block 7. In the process of the sliding sleeve 3 sliding upward, the buckle head 10 will contact the outer peripheral wall of the feed pipe 2. When the buckle head 10 moves the position of the annular groove 9, the buckle head 10 will directly buckle into the slide groove under the action of the torsion spring. This has a certain limiting effect on people sliding the sliding sleeve 3, indicating that people have slid to the appropriate position and do not need to slide upward anymore. After people release the sliding sleeve 3, the sliding sleeve 3 is not easy to slide down under the limiting effect of the buckle head 10. The buckle head 10 is hemispherical, and the hemispherical buckle head 10 makes the contact area with the outer wall of the feed pipe 2 small, so that there is a gap between the buckle head 10 and the outer wall of the feed pipe 2. The friction force is relatively small, so that the sliding sleeve 3 is easy to slide. The feeding tube 2 is provided with a friction part 11 which is always located above the sliding sleeve 3. The outer peripheral wall of the sliding sleeve 3 is provided with a plurality of friction lines. When people need to slide the sliding sleeve 3 upward, due to the resistance of the rubber ring 2, the force required by people at the beginning of sliding is relatively large. People can hold the sliding sleeve 3 with one hand and the friction part 11 on the feeding tube 2 with the other hand, and then slide the sliding sleeve 3 upward with force. The friction coefficient on the friction part 11 is large, which increases the friction force between the hand and the feeding tube 2. The setting of the friction lines increases the friction force between the hand and the sliding sleeve 3. This setting makes it difficult for people to lose their hands during the sliding process. The warehouse body 1 is made of stainless steel material, which ensures the overall strength and life of the warehouse body 1.
