Description

Technical Field

[0001] The utility model relates to the field of storage devices, and particularly relates to a grain inlet mechanism of a grain bin. Background Art

[0002] At present, in the field of grain storage in China, there are mainly silos, shallow silos, steel silos, flat warehouses, etc. for long-term storage or turnover of grain. The storage time of grain is usually very long, which requires grain storage units to take some measures to avoid or reduce the occurrence of mildew, insect pests, etc. in the grain. One of the main measures adopted is to carry out circulating fumigation operation in the bin with highly toxic phosphine gas. This requires that when this operation is carried out, the whole grain bin must be sealed (airtight) and last for a period of time. For this purpose, at present, almost all grain storage bins, especially silos and shallow silos, use manual airtight gates at the grain inlet on the top of the bin and the grain outlet on the bottom of the bin to make the grain bin airtight by closing the airtight gates tightly when needed.

[0003] The existing widely used connecting device of the grain inlet adopts a vertical chute to directly connect the manual gate and the interface of the inlet chute into the bin. The airtight effect is poor, and there are situations such as air leakage or water seepage, which greatly affects the use effect and the food storage is not good. Content of the Utility Model

[0004] The purpose of the utility model is to provide one, aiming at improving the relatively poor grain storage effect of the existing grain bin, resulting in problems such as grain mildew or insect pests.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: A grain inlet mechanism of a grain bin, comprising:

A second flange for docking with the first flange is arranged at one end of the connecting pipe. Symmetrical wedge-shaped slide rails are arranged on the end face of the second flange, and a chute for engaging with the wedge-shaped slide rails is arranged horizontally on the first flange. Locking holes are arranged in a corresponding position on the second flange and the first flange;

[0008] A first sealing ring is arranged on the end face of the sealing cover, and a second sealing ring for corresponding to the first sealing ring is arranged at the port of the feed pipe.

[0009] Preferably, a contour baffle is provided on the second flange and sleeved on the contour edge of the first flange, and a sliding track for axial movement is provided between the contour baffle and the second flange.

[0010] Preferably, the wedge-shaped sliding rail is a T-shaped sliding rail.

[0011] Preferably, the end face of the sealing cover is provided with a convex spherical surface.

[0012] Preferably, a plurality of handwheel locks are further provided. A threaded shaft and a nut locked with the threaded shaft are provided on the handwheel lock. The threaded shaft is arranged in the locking hole, or a plurality of pairs of side ears are oppositely arranged on the connecting pipe and the grain inlet pipe, and the threaded shaft penetrates through the side ears and is locked and arranged.

[0013] Preferably, a heat preservation layer is provided inside the sealing cover.

[0014] Preferably, a fireproof layer is further provided inside the sealing cover.

[0015] Preferably, the side surface of the connecting pipe is an inclined surface that gradually narrows in the direction away from the second flange.

[0034] Embodiment

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a feed inlet mechanism for a granary, including a feed pipe 10 and a connecting mechanism 20. The feed pipe 10 is arranged at the bottom or top of the granary. A sandwich layer is provided on the pipe of the feed pipe 10, and a fireproof filler 101 is arranged in the sandwich layer. A first flange 102 is arranged at the port of the feed pipe 10; the connecting mechanism 20 includes a connecting pipe 201 and a sealing cover 202 arranged at one end of the connecting pipe 201. A second flange 203 for docking with the first flange 102 is arranged at one end of the connecting pipe 201. Symmetrical wedge-shaped slide rails 2031 are arranged on the end face of the second flange 203. A chute 1021 for engaging with the wedge-shaped slide rails 2031 is arranged horizontally on the first flange 102. Locking holes 1022 are arranged in alignment on the second flange 203 and the first flange 102; a first sealing ring 2021 is arranged on the end face of the sealing cover 202, and a second sealing ring 103 in alignment with the first sealing ring 2021 is arranged at the port of the feed pipe 10.

[0036] Specifically, through the cooperation of the wedge-shaped slide rails 2031 and the chute 1021, relatively precise alignment and engagement can be formed, and at the same time, the distance between the connecting pipe 201 and the feed pipe 10 can be limited or adjusted. Then, through the locking holes 1022 in alignment on the second flange 203 and the first flange 102, bolts are used for connection and locking. With the fitting of the first sealing ring 2021 and the second sealing ring 103, the purpose of sealing the position of the feed pipe 10 is achieved. The arrangement of the wedge-shaped slide rails 2031 can ensure stable installation and convenient assembly. After the assembly is completed, the connecting pipe 201 and the feed pipe 10 are not prone to deformation and can ensure the sealing performance for a relatively long time.

[0037] Furthermore, for the fireproof filler 101 that can be designed to be fireproof inside the pipe of the feed pipe 10, such as asbestos; a fireproof coating can also be sprayed on the outer surface layers of the feed pipe 10 and the connecting mechanism 20, such as a solvent-based coating composed of chlorinated rubber, paraffin, and various fireproof additives, to improve the safety performance of the feed pipe 10.

[0038] In terms of sealing performance, the first sealing ring 2021 and the second sealing ring 103 can adopt sealing rings made of silicone or rubber materials, and aluminum foil tape is pasted on the outer surface to prevent adhesion between the first sealing ring 2021 and the second sealing ring 103 during long-term fitting and sealing, which is inconvenient for opening the sealing door, and can improve the service life of the first sealing ring 2021 and the second sealing ring 103 and improve the practicability.

[0039] Further, in this embodiment, the wedge-shaped slide rail 2031 is a T-shaped slide rail. The T-shaped structural slide rail cooperates with the chute 1021, which can effectively prevent the connection mechanism 20 from detaching from the grain inlet pipe 10 on the vertical plane, forming a tight butt joint installation. The sliding movement or assembly is convenient for operation and has good assembly stability.

[0040] As Figure 1 shown, in this embodiment, the end face of the sealing cover 202 is provided with a convex spherical surface 2022. The sealing cover 202 is a spherical surface 2022 with a central bulge. The design of this spherical surface 2022 can effectively prevent water accumulation on the sealing cover 202 and avoid water seeping into the granary through the connection part, resulting in mildew of the grain. Preferably, the size of the central bulge of the spherical surface 2022 of the sealing cover 202 can be 10 mm. It should be recognized that other heights of bulges can also be used, and the effect of preventing water accumulation can also be achieved.

[0041] In this embodiment, a contour baffle 2032 sleeved on the contour edge of the first flange 102 is provided on the second flange 203. A sliding track for axial movement is provided between the contour baffle 2032 and the second flange 203. The setting of the contour baffle 2032 can cover the butt joint position between the connecting pipe 201 and the grain inlet pipe 10, thus avoiding the erosion of rainwater and improving the protection performance. The design of the sliding track can provide a design for the sliding between the contour baffle 2032 and the second flange 203 to ensure the rationality and practicality of the structural cooperation operation.

[0042] Further, as Figure 1 shown, in this embodiment, a heat-insulating layer 2023 is provided inside the sealing cover 202, and a fireproof layer 2024 is also provided inside the sealing cover 202. Specifically, rock wool or glass wool can be provided in the sealing cover 202 to form the heat-insulating layer 2023, and for the fireproof layer 2024, a space for placing fireproof materials can be separated by setting a partition board first, and then asbestos can be filled in this space to form the fireproof layer 2024, so that the overall grain inlet mechanism of the granary has good heat-insulating and fireproof performances and improves the practicality of grain storage.

[0043] As Figure 2 shown, in this embodiment, a plurality of handwheel locks 30 are also provided. The handwheel lock 30 is provided with a threaded shaft and a nut locked to the threaded shaft. The threaded shaft is arranged in the locking hole 1022, or a plurality of pairs of side ears 2012 are oppositely arranged on the connecting pipe 201 and the grain inlet pipe 10, and the threaded shaft penetrates through the side ears 2012 for locking. Therefore, locking can be carried out through the locking hole 1022, or the side ears 2012 can be provided for avoiding locking. The design of the handwheel is convenient for manual operation, that is, locking can be carried out. If a greater locking force is required, tools such as a wrench can be used to improve the convenience of use.

[0044] As shown Figure 1 As shown, in this embodiment, the side surface of the connecting pipe 201 is an inclined surface 2011 that gradually narrows in the direction away from the second flange 203. In this way, it is possible to avoid the sealing cover 202 that is axially abutted from having a stable support in the axial direction, and it is not easy to have axial displacement, and it has good fitting accuracy and sealing performance.

[0045] In this embodiment, the widths of the first sealing ring 2021 and the second sealing ring 103 are 3 - 8 mm, and preferably can be 6 mm. The sealing rings with a certain width can provide good sealing performance after fitting.

[0046] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
