Description

Technical Field

[0001] This utility model relates to the technical field of grain silo top feed inlet structure, specifically to a silo top feed inlet telescopic chute device. Background Technology

[0002] The feed inlet is located at the top of the grain silo, connected to the internal equipment via a vertical pipe. Grain flows rapidly downwards under gravity, directly into the silo. The bottom of this pipe typically features a distributor, some of which are rotatable, to evenly distribute the vertically falling grain throughout the silo, preventing it from accumulating in one spot and forming a spike. For example, the applicant's prior patent (CN221343039U) discloses a rotary distributor that not only achieves rotary distribution but also distributes grain within different radii.

[0003] There is a problem with the sealing between the feed inlet at the top of the silo and the feed pipe; when grain needs to be fed, the plug in the feed pipe is opened and then plugged back in after the grain is fed, but it is not tight. In the later stages of the grain silo, the poor sealing will affect the effectiveness of operations such as circulating fumigation. Utility Model Content

[0004] The purpose of this invention is to provide a telescopic chute device for the top feed inlet of a silo, which solves the problem of poor sealing of the pipe connected to the feed inlet after the grain feeding is completed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic chute device for a silo top inlet includes a first pipe section, a telescopic chute and a second pipe section, wherein the telescopic chute is sleeved and assembled with the first pipe section, and the telescopic chute and the first pipe section are connected by a flexible connection. The second pipe section is located on the upper side of the feed inlet and is used for the lower end of the telescopic chute to abut or extend into it. It also includes a sealing plate for covering the upper opening of the second pipe section.

[0006] Furthermore, the outer side of the first pipe section is provided with a hanging lug, and the bottom of the telescopic chute is provided with a hanging arm, the end of which is provided with a connecting groove or connecting hole for docking with the hanging lug.

[0007] Furthermore, a canvas tube is used to achieve a flexible connection between the telescopic chute and the first pipe section. The canvas tube is located on the outside of the first pipe section, and the hanging arm is located on the periphery of the canvas tube.

[0008] Furthermore, the sealing plate is a detachable movable plate, and the upper pipe opening of the second pipe section is provided with a flange edge for the lower end of the telescopic chute to abut against or connect to the sealing plate.

[0009] Furthermore, the sealing plate is a rectangular plate with flange edges around its perimeter.

[0010] Furthermore, the bottom side of the middle region of the sealing plate is provided with a heat insulation part, which includes a built-in heat insulation layer.

[0011] Furthermore, the cross-section of the insulation section is trapezoidal.

[0012] Furthermore, at least one side of the sealing plate is provided with a handle.

[0013] Furthermore, the handle is convex and includes an elongated hole running vertically through it.

[0014] The beneficial effects of this utility model are: This utility model relates to a telescopic chute device for the top feed inlet of a grain silo. One section of the chute is designed to be vertically extendable. When grain is being fed into the silo, the telescopic chute is lowered to connect with the lower pipe. After the grain has been fed into the silo, the telescopic chute is raised, and the flexible connection retracts, separating the telescopic chute from the lower pipe. A sealing plate is then placed at the opening of the lower pipe to seal it, achieving a good airtight seal. This ingenious design is easy to manufacture, low in cost, and effectively solves the problems existing in the feed inlet structures of some grain silo models. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0018] Embodiments of this utility model: like Figures 1-5 As shown, a telescopic chute device for a grain silo top inlet includes a first pipe section 1, a telescopic chute 5, and a second pipe section 7. The telescopic chute 5 is fitted and assembled with the first pipe section 1, and the telescopic chute 5 and the first pipe section 1 are connected by a flexible connection. The second pipe section 7 is located on the upper side of the inlet 8 and is used for the lower end of the telescopic chute 5 to abut against it. The first pipe section 1 and the second pipe section 7 are actually the chute parts used for feeding, but different names are defined in this embodiment for ease of description and understanding. This embodiment is an improvement on the existing structure. The upper part of the first pipe section 1 is connected to the existing feeding pipeline to receive the transported grain, which flows through the chute to the inlet 8 and enters the silo through a distributor or other diversion device. The inlet 8 refers to the steel sleeve pre-embedded during the construction of the grain silo.

[0019] like Figure 1 As shown, the outer side of the first pipe section 1 is provided with a hanging lug 2, and the bottom of the telescopic chute 5 is provided with a hanging arm 4. The hanging arm 4 is L-shaped, and the end of the hanging arm 4 is provided with a connecting hole for docking with the hanging lug 2. The hanging lug 2 is provided with a through hole. After the connecting hole of the telescopic chute 5 is aligned with the through hole, it can be connected by bolts or pins (axial insertion) to realize the suspension of the telescopic chute 5. At this time, there is a gap between the bottom of the telescopic chute 5 and the upper pipe opening of the second pipe section 7, and a sealing plate 9 needs to be placed thereafter. In other embodiments, in order to facilitate the connection operation, a connecting groove, i.e., an open groove, can also be machined at the end of the hanging arm 4, specifically a C-shaped groove. The hanging lug 2 is provided with a corresponding C-shaped groove, and the bolt can be inserted into the C-shaped groove radially.

[0020] The telescopic chute 5 and the first pipe section 1 are connected by a canvas tube 3. The canvas tube 3 is located on the outside of the first pipe section 1, and the hanging arm 4 is located around the canvas tube 3. The canvas tube 3 can be understood as a cylindrical structure made of canvas that runs vertically through the pipe. The telescopic chute 5 is fitted over the first pipe section 1, and the upper connection point of the canvas tube 3 is located outside the first pipe section 1 (this connection point is a certain distance from the bottom of the first pipe section 1). A flange can be installed outside the first pipe section 1 to connect the upper part of the canvas tube 3, and the connection is achieved by tightening it with bolts.

[0021] like Figure 2As shown, after unscrewing the aforementioned bolts, the telescopic chute 5 can fall downwards under gravity and connect with the upper opening of the second pipe section 7, at which point the grain feeding operation can be performed. In other embodiments, if the diameter of the telescopic chute 5 is smaller than that of the second pipe section 7, the second pipe section 7 is located above the feed inlet 8 and is used to allow the lower end of the telescopic chute 5 to extend into it during feeding.

[0022] like Figures 3 to 5 As shown, the telescopic chute 5 device at the top feed inlet 8 of the silo also includes a sealing plate 9, which is used to cover the upper opening of the second pipe section 7.

[0023] like Figure 1 As shown, the sealing plate 9 is a detachable movable plate. The upper opening of the second pipe section 7 is provided with a flange edge, defined as the first flange edge 71, for the lower end of the telescopic chute 5 to abut against or connect to the sealing plate 9. During feeding, the sealing plate 9 is removed, and the upper opening of the second pipe section 7 can mate with the lower end of the telescopic chute 5. When the telescopic chute 5 is raised and bolted to the lug 2, the sealing plate 9 can then be operated to cover the upper opening of the second pipe section 7. Figure 3 As shown, the sealing plate 9 can seal the pipe opening after the grain is fed in, and it meets the requirements for the airtightness of the grain silo.

[0024] like Figure 1 As shown, the lower end of the telescopic chute 5 abuts against the first flange edge 71, or can be inserted into the second pipe section 7. However, for better results, a second flange edge 51 is provided at the lower end of the telescopic chute 5, which is flanged and connected to the first flange edge 71. This provides good stability and prevents dust and impurities from overflowing from here.

[0025] like Figure 4 As shown, the sealing plate 9 is a rectangular plate with flange edges on all four sides, which is adapted to the upper part of the second pipe opening. The two can be connected by bolts. Figure 1 As shown, a hollow rectangular rubber gasket 6 can be attached to the upper side of the flange at the upper opening of the second pipe section 7. The gasket has through holes corresponding to the flange holes. Under the tightening of the bolts, the sealing plate 9 can seal the second pipe section 7. When grain needs to be fed in, the sealing plate 9 can be removed, and then the telescopic chute 5 can be lowered. Due to the design of the rectangular gasket, the telescopic chute 5 also has a certain buffering effect.

[0026] like Figure 5 As shown, a heat insulation section 92 is provided on the bottom side of the middle area of ​​the sealing plate 9. The heat insulation section 92 includes a built-in heat insulation layer, such as using filled heat insulation cotton as the heat insulation layer. The cross-section of the heat insulation section 92 is trapezoidal, larger at the top and smaller at the bottom. The outer diameter of the upper part of the heat insulation section 92 is adapted to the inner diameter of the second pipe section 7, which not only provides heat insulation but also provides a certain positioning function, making it easy for the sealing plate 9 to be quickly installed in place (utilizing the outer conical surface of the heat insulation section 92).

[0027] like Figure 4 As shown, the sealing plate 9 has a handle on at least one side; in this embodiment, one handle is designed on each side. The handle is protruding and includes an elongated hole 91 that runs vertically through it, allowing the worker to hold it during operation for ease of use.

[0028] In this embodiment, the lifting of the telescopic chute 5 and the installation and disassembly of the sealing plate 9 are all done manually. This is because grain storage is concentrated in a few days during a specific season each year and is not used particularly frequently. Manual operation not only meets the design purpose but also reduces costs and is more conducive to promotion and application or modification of existing devices.

[0029] In other embodiments, if electric control is required, an electric telescopic rod can be fixed to the outside of the feed inlet 8, with its upper part connected to the bottom outside of the telescopic chute 5, for controlling the lifting and lowering of the telescopic chute 5. A 90-degree angle cylinder is used to control the movement of the sealing plate 9. One corner of the sealing plate 9 is connected to the pressure arm of the 90-degree angle cylinder. The rotation of the angle cylinder can rotate the sealing plate 9 into place or out, and the extension and retraction of the angle cylinder can achieve the pressing and lifting release of the sealing plate 9.
