Description

Technical Field

[0001] This application relates to the field of grain conveying technology, specifically to a convenient telescopic chute structure for preventing leakage at the grain inlet of a warehouse. Background Technology

[0002] In grain storage, the airtightness of the warehouse is a key indicator, and the sealing treatment of the inlet of the shallow circular silo is a crucial factor affecting the overall airtightness. Currently, the system mainly uses two isolation methods: one is gate valve sealing, which is widely used on the connecting chute between the unloading conveyor and the inlet of the shallow circular silo.

[0003] However, the sealing structure of gate valves has inherent defects, making it difficult to create a completely sealed space. Rainwater can easily seep into the storage silo along the valve body gaps, directly threatening the safety of stored grain. At the same time, these leaks significantly reduce the airtightness of the storage silo, hindering the effective implementation of technologies such as controlled atmosphere storage and mechanical ventilation. Secondly, there is the blind flange sealing method. Some units choose to remove part of the traditional chute structure and install blind flanges at the grain inlet for sealing. While this method can effectively isolate rainwater, the blind flanges require frequent disassembly and reassembly, which is time-consuming and labor-intensive, severely restricting the efficiency of grain conveying operations and failing to meet the needs of efficient storage.

[0004] Therefore, there is an urgent need for a convenient telescopic chute structure that ensures sealing performance and allows for quick assembly and disassembly. Utility Model Content

When the lower section of the chute is not in use, the cover plate seals the upper end of the lower section of the chute. During operation, the middle section of the chute is fixed to the lower section of the chute with bolts to form a grain conveying channel; A limit mechanism is installed on the outer side of the middle section of the chute to restrict the descent of the middle section of the chute.

[0009] Optionally, a limiting rod is installed on the side of the middle section of the chute away from the limiting mechanism, and the limiting rod is slidably connected to the upper section of the chute.

[0010] Optionally, a handle is mounted on the outer side of the fixing plate to provide a gripping position.

[0014] Optionally, an anti-detachment frame is fixed at the lower end of the upper section of the chute, and the length and width dimensions of the anti-detachment frame are both larger than the length and width dimensions of the inner opening of the limiting frame.

[0015] Optionally, an insulation board is also installed at the connection between the cover plate and the lower section of the chute, and the insulation board is in contact with the inner wall of the lower section of the chute.

[0016] Compared with the prior art, this application has at least the following beneficial effects: 1.

[0021] The following is in conjunction with the appendix Figure 1-10 The present application will be further described in detail through specific embodiments.

[0022] This utility model provides a convenient telescopic chute structure for preventing leakage at the grain inlet of a warehouse, including an upper section 1 of the chute, a middle section 2 of the chute installed on the lower side of the upper section 1, and a locking mechanism 3 installed at the upper end of the middle section 2. The middle section 2 of the chute is detachably connected to the upper section 1 of the chute through the locking mechanism 3, so that the middle section 2 of the chute can be quickly disassembled and assembled with the upper section 1 of the chute. The upper section 1 of the chute is connected to the unloading belt conveyor; The length and width of the middle section 2 of the chute are both larger than the length and width of the upper section 1 of the chute; The lower end of the middle section 2 of the chute is bolted with the lower section 7 of the chute. The lower section 7 of the chute is fixedly connected to the feed inlet on the top of the silo. When the lower section 7 of the chute is not in use, the upper end of the lower section 7 of the chute is sealed by the cover plate 8. During operation, the middle section 2 of the chute is disassembled from the upper section 1 of the chute, and the middle section 2 of the chute is lowered. The middle section 2 of the chute is fixed to the lower section 7 of the chute by bolts, thus constructing a complete grain conveying channel. The locking mechanism 3 includes a latch 301, which is installed on the outside of the middle section 2 of the chute. The upper end of the latch 301 is provided with a limiting block 302 fixed to the outside of the upper section 1 of the chute, so that the middle section 2 of the chute and the upper section 1 of the chute can be quickly disassembled and assembled. A limit mechanism 5 is installed on the outer side of the middle section 2 of the chute to restrict the descent of the middle section 2 of the chute. The limiting mechanism 5 includes a mounting plate 501. The upper end of the mounting plate 501 is fixedly mounted on the outer end of the upper section 1 of the chute. A connecting plate 502 is slidably mounted on the lower end of the mounting plate 501. An adjusting rod 505 is threadedly connected to the inner side of the connecting plate 502. A fixing plate 504 is fixed to the outer end of the middle section 2 of the chute. The lower end of the adjusting rod 505 is rotatably connected to the fixing plate 504. Specifically, when the latch 301 is pulled upward, the upper section 1 and the middle section 2 of the chute are disassembled, allowing the interior of the upper section 1 and the middle section 2 of the chute to move. Then, the adjusting rod 505 is rotated, and the distance between the middle section 2 and the upper section 1 of the chute is adjusted by using the threaded connection between the adjusting rod 505 and the connecting plate 502. This prevents the middle section 2 of the chute from falling directly downward after the locking mechanism 3 is released from fixing the upper section 1 and the middle section 2 of the chute. The locking mechanism 3 can also ensure the stable fixing between the upper section 1 and the middle section 2 of the chute, preventing the threaded connection from slipping. A limit rod 6 is installed on the side of the middle section 2 of the chute away from the limit mechanism 5. The limit rod 6 is slidably connected to the upper section 1 of the chute to prevent the middle section 2 of the chute from tilting when the limit mechanism 5 is limited on one side. A handle 4 is mounted on the outer side of the mounting plate 504 to provide a gripping position; The longitudinal section of the mounting plate 501 is "L" shaped. The mounting plate 501 and the connecting plate 502 form an elastic connection, which allows for a small distance adjustment between the connecting plate 502 and the mounting plate 501. Under the over-adjustment of the adjusting rod 505, the spring between the connecting plate 502 and the mounting plate 501 deforms, thereby ensuring a stable fit between the middle section 2 and the lower section 7 of the chute, without affecting the seal between the middle section 2 and the lower section 7 of the chute. A limiting plate 503 is fixed to the outside of the mounting plate 501 to limit the downward movement distance of the middle section 2 of the chute and avoid affecting the movement of the connecting plate 502. A limiting frame 11 is installed at the upper end of the middle section 2 of the chute, and a 9 is installed at the connection between the limiting frame 11 and the middle section 2 of the chute to compensate for the gap at the connection. The lower end of the upper section 1 of the chute is fixed with an anti-detachment frame 12. The length and width of the anti-detachment frame 12 are both larger than the length and width of the inner opening of the limiting frame 11, thereby preventing the anti-detachment frame 12 from detaching from the limiting frame 11, and thus preventing the upper section 1 of the chute from completely separating from the middle section 2 of the chute. The connection between the upper section 11 and the middle section 2 of the chute and the connection between the middle section 2 and the lower section 7 of the chute are provided with corresponding hole structures for bolt installation, so as to realize the bolt connection of adjacent pipes and facilitate quick assembly and disassembly. An insulation board 10 is also installed at the lower end of the cover plate 8. The insulation board 10 is in contact with the inner wall of the lower section 7 of the chute to ensure the insulation performance of the upper opening of the lower section 7 of the chute.

[0023] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
