Description

Technical Field

[0001] This invention relates to the field of pipeline technology, specifically a leak-proof material feeding pipe. Background Technology

[0002] The feed pipe is a core component of the feed conveying system, responsible for quickly and smoothly transporting feed from the feed tower to the designated feeding point. Its design must balance efficient conveying with anti-clogging and anti-leakage. It usually adopts a spiral auger structure to ensure that the feed flows evenly in the pipe. Depending on the application scenario, different pipe materials can be selected to cope with the corrosiveness of different feed components. In modern automated systems, the feed pipe is linked with motors and sensors to achieve precise feeding, significantly improving the operational efficiency of farms and reducing labor costs.

[0003] However, the existing technology has the following shortcomings: the current feeding pipe adopts the traditional single-point rigid suspension, and is suspended outdoors by direct hanging of iron wire or steel cable. Because it cannot buffer the vibration of the auger and the weight of the feed, the pipe body and joints become fatigued and loose. In addition, the pipe is embrittled by long-term exposure to sunlight outdoors and cracks in the stress concentration area of ​​the joint. Furthermore, the rigid connection of the flange at the joint will eventually lead to the end of the feeding pipe breaking due to vibration and other factors, resulting in material leakage.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies are not connected through a transitional structure, but rather formed as a whole through a connecting structure. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] The present invention will be further described below with reference to the accompanying drawings: Example 1: As shown in the attached document Figure 1 To be continued Figure 7 As shown: This embodiment provides a leak-proof feeding pipe, including a pipe support device 1, a pipe 2 mounted on the pipe support device 1, a fixed base plate 3 mounted below the pipe support device 1, a column 11 inside the pipe support device 1, an L-shaped locking box 12 fixed at the top of the column 11, a pipe buffer frame 13 connected to the L-shaped locking box 12, a cover side wing frame 14 on both sides of the pipe buffer frame 13, and a cover plate 15 covering the space between the cover side wing frames 14; an outer bellows sleeve 22 connected to the pipe 2, flange connecting pieces 21 installed at both ends of the outer bellows sleeve 22, an inner telescopic connecting rubber sleeve 23 installed inside the outer bellows sleeve 22, and sleeve rings 24 installed at both ends of the inner telescopic connecting rubber sleeve 23; a three-way frame plate 141 is installed inside the cover side wing frame 14, and an arc-shaped plate insert rod 142 is nested on the three-way frame plate 141.

[0024] Furthermore, the base plate 3 is mainly used for fixing the column 11, and with the assistance of the L-shaped locking box 12 and the material pipe buffer frame 13 on the column 11, it completes the fixing and support of the material pipe 2, so that it can be suspended outdoors.

[0025] Furthermore, the L-shaped locking box 12 is L-shaped in general, with the shorter end fixed to the end of the column 11, while the longer end is a threaded shaft, used to fix the material tube buffer frame 13, and the arrangement angle of the material tube buffer frame 13 can be adjusted through the rotation process.

[0026] The material pipe buffer frame 13 is equipped with a threaded sleeve beam 131. A V-shaped fixing strip 132 is installed on the outer surface of the threaded sleeve beam 131. A fixing block 133 is fixed at the center of the outer wall of the V-shaped fixing strip 132. Connecting screws 134 are installed on both the front and rear surfaces of the fixing block 133. A teardrop-shaped frame 135 is fixed below both ends of the V-shaped fixing strip 132. A pipe clamping device 136 is installed on each connecting screw 134. An adjusting lock cylinder 137 is connected between even numbers of pipe clamping devices 136. A locking clamp 1351 is installed on the teardrop-shaped frame 135, and a locking plate sleeve 1352 is installed on the outer wall of the teardrop-shaped frame 135.

[0027] Furthermore, the threaded sleeve beam 131 has a threaded hole inside, which is used to connect the threaded shaft inside the L-shaped locking box 12 to the threaded shaft, thus completing the connection and fastening.

[0028] Furthermore, the connecting screw 134 fixed at the center of the front and rear surfaces of the fixing block 133 on the strip is mainly used for the fixed support of the pipe clamping device 136, so that the pipe clamping device 136 is fixed and prevented from swinging.

[0029] Furthermore, two clamping devices 136 need to be used together, and they are connected in conjunction with the adjusting locking cylinder 137 to allow the components on the arc-shaped lower support 1367 inside the clamping device 136 to change angle.

[0030] The clamping device 136 includes a Y-shaped frame 1361, a fixing ring 1362 fixed on the Y-shaped frame 1361, a connecting column 1363 connected inside the Y-shaped frame 1361, a buffer assembly 1364 connected below the connecting column 1363, a rubber upper clamp 1365 installed on the top of the buffer assembly 1364, an even number of height-adapting rods 1366 connected on the Y-shaped frame 1361, and an arc-shaped lower support 1367 connected to the end of the even number of height-adapting rods 1366.

[0031] Furthermore, the Y-shaped frame 1361 is in the shape of a "Y" with threaded holes inside the intersection for connecting to the connecting post 1363, and the buffer assembly 1364, which is indirectly connected to the connecting post 1363, is disposed between the Y-shaped frames 1361.

[0032] Furthermore, the height adjustment rod 1366 is mainly used for the connection between the Y-shaped frame 1361 and the arc-shaped lower support 1367, and works with the rubber upper clamp 1365 to clamp different diameters of the material tube 2, thus enabling height adjustment.

[0033] Furthermore, the rubber upper clamp 1365 adopts a structural design of "inner iron casting plus outer rubber coating". The inner iron frame achieves support strength, while the outer rubber coating can reduce the adverse effects on the clamping of the material tube 2.

[0034] The buffer assembly 1364 includes an outer shell 13641, an inner sleeve post 13642 embedded within the outer shell 13641, an outer connecting cylinder 13645 nested on the inner sleeve post 13642, an inner support spring 13643 nested outside the outer connecting cylinder 13645 and the inner sleeve post 13642, several limiting posts 13644 surrounding the inner sleeve post 13642, a movable top block 13646 on the inner sleeve post 13645, and a rubber top ring 13647 installed on the inner surface of the outer shell 13641.

[0035] Furthermore, the outer shell 13641 has corresponding sliding grooves on its surface. The sliding grooves allow the movable top block 13646 on the cylinder to move. As the cylinder vibrates, the inner support spring 13643 is quickly reset by pressing down on it.

[0036] Furthermore, a rubber top ring 13647 is disposed inside the outer shell 13641 and fixed by the inner surface of the outer shell 13641 to support the movable top block 13646 on the cylinder after the inner support spring 13643 is lifted and reset, thus avoiding resonance.

[0037] Among them, the arc-shaped lower support 1367 has a hinged sleeve 13671 nested in the center, the surface of the hinged sleeve 13671 is fixed with a rubber lower clamp 13672, an even number of upper protrusions 13673 are installed below the hinged sleeve 13671, and a hinged angle adjusting tube 13674 is installed between the even number of upper protrusions 13673.

[0038] Furthermore, the lower rubber clamp 13672 has the same structure as the upper rubber clamp 1365. The lower rubber clamp 13672 is adjusted by means of the hinged sleeve 13671, and the angle is fixed by the hinged angle adjusting cylinder 13674 between the lugs 13673 on the platform below the hinged sleeve 13671 in conjunction with the adjusting locking cylinder 137.

[0039] The specific working principle is as follows: This invention uses a column 11 and a base plate 3 to fix the ground, and then connects the material pipe buffer frame 13 to the L-shaped locking box 12. The threaded sleeve beam 131 is fixed to the L-shaped locking box 12, and the fixing block 133 below the V-shaped fixing strip 132 is used to install the clamping device 136 through the connecting screw 134. The teardrop-shaped frame 135 at both ends of the V-shaped fixing strip 132 are connected to the cover side wing 14. Then the cover plate 15 is installed on the cover side wing 14. The material pipe 2 is connected to the auger pipe on the material box at one end. The material pipe 2 passes through the clamping device 136 and is connected to the flange connecting piece 21 at one end of the outer bellows sleeve 22. Then it is connected to another material pipe from the flange connecting piece 21 at the other end. During the operation of the auger, the material pipe 2 is subjected to the rubber lower clamp 13672 and the rubber upper clamp 1365. The vibration of the auger is absorbed by the outer connecting cylinder 13645 connected to the upper rubber clamp 1365, which drives the movable top block 13646 on the cylinder to move in the outer casing 13641. At the same time, it squeezes the built-in inner support spring 13643, allowing the inner support spring 13643 to quickly return to its original position after compression. During the return, the top of the movable top block 13646 on the cylinder is buffered by the rubber top ring 13647 to prevent resonance. The lower rubber clamp 13672 is fixed between the lugs 13673 on the upper platform of the hinged sleeve 13671 by the hinged angle adjusting cylinder 13674, which, together with the screw nut, adjusts the left and right sides and the adjusting lock cylinder 137 to form a fixed position. This keeps the lower rubber clamp 13672 at a fixed angle, and the upper rubber clamp 1365 is fixed by bolts to eliminate vibration and prevent the material pipe end from breaking and leaking due to vibration and other factors.

[0040] Example 2: As shown in the attached document Figure 2 To be continued Figure 3 As shown: The material pipe support device 1 includes a column 11 with an L-shaped locking box 12 fixed to its top. A material pipe buffer frame 13 is connected to the L-shaped locking box 12. Covering side wings 14 are provided on both sides of the material pipe buffer frame 13, and a cover plate 15 covers the space between the covering side wings 14. A threaded sleeve beam 131 is provided inside the material pipe buffer frame 13. A V-shaped fixing strip 132 is installed on the outer surface of the threaded sleeve beam 131. A fixing block 133 is fixed at the center of the outer wall of the V-shaped fixing strip 132. Connecting screws 134 are installed on the front and rear surfaces of the fixing block 133. A teardrop-shaped frame 135 is fixed below both ends of the V-shaped fixing strip 132. A pipe clamping device 136 is installed on each of the connecting screws 134. A three-way frame plate 141 is provided inside the covering side wings 14, and an arc-shaped plate insert rod 142 is nested on the three-way frame plate 141. A locking clamp 1351 is installed on the teardrop-shaped frame 135, and a locking plate sleeve 1352 is installed on the outer wall of the teardrop-shaped frame 135.

[0041] Furthermore, the three-way support plate 141 has three plates facing different directions, and nesting holes are provided in the plates. The arc plate insert rod 142 is nested through the holes to fix the arc plate insert rod 142.

[0042] Furthermore, the arc plate insert rod 142 is used to fix the cover plate 15 between them, thereby covering the outer gusset sleeve at the connection of the lower material pipe buffer frame 13 and the material pipe 2, and completing the sunshade and rain protection work.

[0043] Furthermore, the teardrop-shaped support 135 mainly secures the three-way support plate 141 by the locking sleeve 1352 on the outer wall, and then tightens it with bolts to prevent the three-way support plate 141 from shifting.

[0044] The specific working principle is as follows: This invention fixes the L-shaped locking box 12 to the end of the column 11, then connects the material tube buffer frame 13 to the L-shaped locking box 12, and finally fixes the three-way frame plate 141 with the locking plate sleeve 1352 on the outer wall of the teardrop-shaped frame 135. After fixing, the arc plate insert 142 is inserted into the three-way frame plate 141, and the cover plate 15 is fixed above the arc plate insert 142, so that the connecting structure of the material tube buffer frame 13 and the end of the material tube forms a cover. By covering the outer gusset sleeve of the end of the material tube and the material tube buffer frame, the two are protected from external dust, sunlight and rain erosion, thus improving the overall durability. Example 3: As shown in the attached document Figure 7 As shown: Among them, the material pipe 2 is connected to an outer bellows sleeve 22, and flange connecting pieces 21 are installed at both ends of the outer bellows sleeve 22. An inner telescopic connecting rubber sleeve 23 is installed inside the outer bellows sleeve 22, and sleeve rings 24 are provided at both ends of the inner telescopic connecting rubber sleeve 23.

[0045] Furthermore, flange connecting pieces 21 are provided at both ends of the material pipe 2, and the same flange connecting pieces 21 are provided at both ends of the outer bellows sleeve 22. Then, the flange connecting pieces 21 on the outer bellows sleeve 22 are connected to the flange connecting pieces 21 on the material pipe 2 at the connection point of the material pipe 2. Finally, the vibration transmission of the rigid connection is eliminated by the tensile properties of the outer bellows sleeve 22 itself.

[0046] Furthermore, the inner telescopic connecting rubber sleeve 23 of the outer gusset sleeve 22 is mainly nested into the inside of the material tube 2 through the sleeve ring 24 connected at both ends. When the material tube 2 is displaced, the material transmitted in the material tube 2 enters from the sleeve ring 24 and is output to another material tube from the sleeve ring 24 at the other end.

[0047] Furthermore, at the connection point between material pipe 2 and another material pipe, an outer gusset 22 and its internal components need to be installed.

[0048] The specific working principle is as follows: This invention connects material pipe 2 to another material pipe. Both ends are connected by flange connecting pieces 21, with sealing rings embedded in the flange connecting pieces 21 at both ends of the outer bellows sleeve 22. 3-4 disc spring washers are installed at the threaded holes on the outside for pre-tightening, and finally fixed with bolts. The sleeve ring 24 is adapted to the inner diameter of the material pipe 2 to form a double-end nest. When the material is conveyed in the material pipe 2, the outer bellows sleeve 22 and the inner telescopic connecting sleeve 23 work together to buffer its displacement, ensuring the continuous conveying of the material and preventing material leakage due to breakage at the end of the material pipe caused by vibration.
