Description

Technical Field

[0001] This utility model relates to the field of grain conveying equipment, specifically a main pipeline anti-blocking device for rice conveying. Background Technology

[0002] Rice is a staple food made from paddy through processes such as cleaning, hulling, and milling. Usually, when processing raw rice, it is necessary to transport the rice, and the transport equipment is a pipeline.

[0003] However, the existing main pipeline system for rice transportation has the following defects during operation: When rice is transported inside the pipeline, during the transportation process, when passing through pipe bends and diameter reduction sections, vertical lifting sections, and downstream of tees and valves, due to the lack of a mechanism to vibrate and clear the material, the material is prone to blockage in the pipeline due to adhesion, bridging, or static friction when passing through these paths, thus affecting the transportation of the material. Utility Model Content

[0004] This utility model aims to provide a main pipeline anti-blockage device for rice transportation. It is mainly used to solve the problem that the existing technology lacks a mechanism to vibrate and clear the material, which makes the transportation pipeline prone to blockage due to material adhesion, bridging or static friction when the material passes through pipe bends and diameter reduction sections, vertical lifting sections and downstream of tees and valves, thus affecting the material transportation technology.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A main pipeline anti-clogging device for rice transportation includes a transportation pipeline, a pneumatic hammer installed on the outer wall of the transportation pipeline, a time relay installed at the control end of the pneumatic hammer, a striking hole opened on the outer wall of the transportation pipeline corresponding to the output end of the pneumatic hammer, an installation hole opened inside the transportation pipeline communicating with the striking hole, a fixing plate fixedly connected to the inner wall of the installation hole near the inner wall of the transportation pipeline, a moving rod slidingly passing through both sides of the fixing plate, one end of the moving rod extending into the inside of the striking hole, the other end extending into the inside of the transportation pipeline, and an agitator fixedly connected to one end of the moving rod near the inside of the transportation pipeline, a support plate fixedly connected to the outer wall of the moving rod near the inside of the installation hole, and a return spring provided between the outer wall of the moving rod near the fixing plate and the support plate.

[0007] The working principle and beneficial effects of this utility model:

[0008] 1. Working Principle: The pneumatic hammer can be intermittently activated via a time relay, causing its output end to strike the striking hole. This generates vibration in the conveying pipe, facilitating the clearing of materials accumulated inside. Simultaneously, when the output end of the pneumatic hammer contacts the inner wall of the striking hole, it drives a moving rod to move into the conveying pipe. This moving rod, in turn, causes a stirring rod to move horizontally within the pipe. When the pneumatic hammer is installed in a location prone to blockage, the moving stirring rod, in conjunction with the material, directly contacts the material, further ensuring smooth material transport within the pipe. A return spring resets the moving rod, allowing it to move again the next time the pneumatic hammer's output end strikes the striking hole.

[0009] 2. Beneficial effects:

[0010] (1) The pneumatic hammer can be intermittently activated by a time relay, so that the output end of the pneumatic hammer strikes the striking hole, thereby generating vibration force in the conveying pipeline, which facilitates the unblocking of materials accumulated inside the conveying pipeline. At the same time, when the output end of the pneumatic hammer contacts the inner wall of the striking hole, the output end of the pneumatic hammer drives the moving rod to move into the conveying pipeline. Thus, the moving rod drives the stirring rod and the extension rod to move horizontally inside the conveying pipeline. When the pneumatic hammer is installed in a position in the conveying pipeline that is prone to blockage, it works in conjunction with the horizontally moving stirring rod and the extension rod to directly contact the material, thereby further ensuring that the material can be smoothly conveyed inside the conveying pipeline. The return spring drives the support plate to slide inside the mounting hole, thereby resetting the moving rod, which is convenient to move again when the output end of the pneumatic hammer strikes the striking hole.

[0011] Preferably, a second connecting flange is installed at the bottom end of the conveying pipe, and a conveying bag is installed at the bottom end of the conveying pipe through the second connecting flange. The conveying bag facilitates connection with an external vibrating screen and facilitates the conveying of grain.

[0012] Preferably, a plurality of support blocks are fixedly connected to the outer wall of the conveying pipe near the output end of the pneumatic hammer. The plurality of support blocks are arranged in a circular array at equal intervals along the periphery of the pneumatic hammer. One end of the plurality of support blocks is fixedly connected to the same first connecting flange. One end of the plurality of support blocks is installed to the pneumatic hammer through the same first connecting flange, and the output end of the pneumatic hammer passes sequentially between the first connecting flange and the plurality of support blocks. Due to the function of the time relay, an electrical signal can be intermittently transmitted to the starting hammer, thereby controlling the pneumatic hammer to start. At this time, the output end of the pneumatic hammer strikes the striking hole, which facilitates the transmission of vibration force to the conveying pipe. The vibration force inside the conveying pipe facilitates the clearing of materials accumulated inside the conveying pipe.

[0013] Preferably, two guide rods are fixedly connected to one side of the fixed plate near the outer wall of the movable rod. The two guide rods are arranged symmetrically in a circular array. The two guide rods penetrate the support plate, and the support plate and the two guide rods are slidably connected. A baffle is fixedly connected to one end of each of the two guide rods. Due to the function of the baffle, it is convenient to restrict the movement of the support plate and prevent the support plate from dislodging from the mounting hole.

[0014] Preferably, the reset spring is sleeved on the outer wall of the guide rod, with one end of the reset spring fixedly connected to one side of the fixed plate and the other end fixedly connected to one side of the support plate. The reaction force of the reset spring facilitates the reset of the support plate. At this time, the support plate moves to the outside of the conveying pipe on the outer wall of the guide rod until one side of the support plate contacts the side of the baffle, thereby completing the reset of the moving rod.

[0015] Preferably, the outer wall of the support plate is adapted to the outer wall of the mounting hole; when the moving rod drives the support plate to move, the support plate can only move laterally inside the mounting hole.

[0016] Preferably, the outer wall of the stirring rod is fixedly connected to two sets of extension rods, which are arranged symmetrically in a ring array. Each set of extension rods has several rods, and the rods in each set are arranged in a linear array at equal intervals along the radial direction of the stirring rod. Due to the function of the extension rods, the contact area between the stirring rod and the material is increased, thereby further ensuring that the material can be smoothly conveyed inside the conveying pipeline.

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, a main pipeline anti-clogging device for rice transportation includes a transportation pipeline 1, a second connecting flange 17 installed at the bottom end of the transportation pipeline 1, and a transportation bag 2 installed at the bottom end of the transportation pipeline 1 through the second connecting flange 17. A pneumatic hammer 4, model FP-50-U, is installed on the outer wall of the transportation pipeline 1. A time relay 5 is installed at the control end of the pneumatic hammer 4. The input end of the time relay 5 is electrically connected to the output end of an external power supply. The time relay 5 is set to trigger the pneumatic hammer 4 once every ten seconds, continuously striking for two seconds. Several support blocks 3 are fixedly connected to the outer wall of the transportation pipeline 1 near the output end of the pneumatic hammer 4. Blocks 3 are arranged in a ring array at equal intervals around the pneumatic hammer 4. One end of several support blocks 3 is fixedly connected to the same first connecting flange 16. One end of several support blocks 3 is installed to the pneumatic hammer 4 through the same first connecting flange 16. The output end of the pneumatic hammer 4 passes through the first connecting flange 16 and several support blocks 3 in sequence. Due to the function of the time relay 5, an electrical signal can be intermittently transmitted to the starting hammer to control the pneumatic hammer 4 to start. At this time, the output end of the pneumatic hammer 4 strikes the striking hole 6, which facilitates the transmission of vibration force to the conveying pipe 1. The vibration force inside the conveying pipe 1 facilitates the unblocking of the material accumulated inside the conveying pipe 1.

[0024] A striking hole 6 is provided on the outer wall of the conveying pipe 1 corresponding to the output end of the pneumatic hammer 4. An installation hole 7 communicating with the striking hole 6 is provided inside the conveying pipe 1. A fixing plate 8 is fixedly connected to the inner wall of the installation hole 7 near the inner wall of the conveying pipe 1. A single moving rod 9 slides through both sides of the fixing plate 8. One end of the moving rod 9 extends into the striking hole 6, and the other end extends into the conveying pipe 1. Two guide rods 11 are fixedly connected to one side of the fixing plate 8 near the outer wall of the moving rod 9. The two guide rods 11 are arranged symmetrically in a circular array and pass through a support plate 10. The outer wall of the support plate 10 is adapted to the outer wall of the installation hole 7, and the support plate 10 and the two guide rods 11 are slidably connected. A baffle 12 is fixedly connected to one end of each guide rod 11. One end of the moving rod 9 is fixedly connected to an agitator 14 near the inside of the conveying pipe 1. Two sets of extension rods 15 are fixedly connected to the outer wall of the agitator 14. The two sets of extension rods 15 are arranged in a circular array symmetrically. Each set of extension rods 15 has several extension rods. The extension rods 15 in each set are arranged in a linear array at equal intervals along the radial direction of the agitator 14. A support plate 10 is fixedly connected to the outer wall of the moving rod 9 near the inside of the mounting hole 7. A return spring 13 is provided between the fixed plate 8 and the support plate 10 near the outer wall of the moving rod 9. At the same time, when the moving rod 9 moves into the conveying pipe 1, the moving rod 9 drives the support plate 10 to move inside the mounting hole 7, so that the support plate 10 moves on the outer wall of the two guide rods 11, and then the support plate 10 drives the return spring 13 to compress.

[0025] A return spring 13 is sleeved on the outer wall of the guide rod 11. One end of the return spring 13 is fixedly connected to one side of the fixed plate 8, and the other end is fixedly connected to one side of the support plate 10. When the output end of the pneumatic hammer 4 contacts the inner wall of the striking hole 6, the output end of the pneumatic hammer 4 contacts one end of the moving rod 9. At this time, the outer wall of the moving rod 9 slides inside the fixed plate 8, causing one end of it to move into the conveying pipe 1. Thus, the moving rod 9 drives the stirring rod 14 and the extension rod 15 to translate inside the conveying pipe 1. Therefore, when the pneumatic hammer 4 is installed in a position in the conveying pipe 1 where blockage is likely to occur, the translating stirring rod 14 and the extension rod 15 directly contact the material. Due to the function of the extension rod 15, it is easier to increase the size of the stirring rod 14. The contact area with the material is increased to further ensure that the material can be smoothly conveyed inside the conveying pipe 1. When the output end of the pneumatic hammer 4 separates from the moving rod 9, the reaction force of the return spring 13 facilitates the reset of the support plate 10. At this time, the support plate 10 moves to the outside of the conveying pipe 1 on the outer wall of the guide rod 11 until one side of the support plate 10 contacts the other side of the baffle 12, thus completing the reset of the moving rod 9. This facilitates the next movement as the output end of the pneumatic hammer 4 hits the striking hole 6. Since only a part of one end of the moving rod 9 is in the striking hole 6, when the output end of the pneumatic hammer 4 contacts the moving rod 9, it can both drive the moving rod 9 to move and will not affect the transmission of vibration force too much.

[0026] As described above, the specific implementation of this utility model is as follows: When materials are conveyed inside the conveying pipe 1, at locations prone to blockage, such as elbows and reducing sections, vertical lifting sections, and downstream of tees and valves, material adhesion, bridging, or static friction can easily cause blockages in the conveying pipe 1. At this time, due to the action of the time relay 5, an electrical signal can be intermittently transmitted to the starting hammer, thereby controlling the pneumatic hammer 4 to start. At this time, the output end of the pneumatic hammer 4 strikes the striking hole 6, which facilitates the transmission of vibration force to the conveying pipe 1. The vibration force inside the conveying pipe 1 facilitates the unblocking of materials accumulated inside the conveying pipe 1. At the same time, when the output end of the pneumatic hammer 4 contacts the inner wall of the striking hole 6, the output end of the pneumatic hammer 4 contacts one end of the moving rod 9. At this time, the outer wall of the moving rod 9 slides inside the fixed plate 8, causing one end of it to move into the conveying pipe 1. Thus, the moving rod 9 drives the stirring rod 14 and the extension rod 15 to move horizontally inside the conveying pipe 1. Therefore, when the pneumatic hammer 4 is installed at a location prone to blockage in the conveying pipe 1, it works in conjunction with the horizontally moving stirring rod 14. The extension rod 15 is in direct contact with the material. Due to the function of the extension rod 15, the contact area between the stirring rod 14 and the material is increased, thereby further ensuring that the material can be smoothly conveyed inside the conveying pipe 1. At the same time, when the moving rod 9 moves into the conveying pipe 1, the moving rod 9 drives the support plate 10 to move inside the mounting hole 7, thereby the support plate 10 moves on the outer wall of the two guide rods 11. Then the support plate 10 drives the return spring 13 to compress. When the output end of the pneumatic hammer 4 separates from the moving rod 9, due to the reaction force of the return spring 13, the support plate 10 is easily driven to reset. At this time, the support plate 10 moves on the outer wall of the guide rod 11 to the outside of the conveying pipe 1 until one side of the support plate 10 contacts the side of the baffle 12, thereby completing the reset of the moving rod 9, which is convenient for the next movement as the output end of the pneumatic hammer 4 hits the striking hole 6. Since only a part of one end of the moving rod 9 is in the striking hole 6, when the output end of the pneumatic hammer 4 contacts the moving rod 9, it can drive the moving rod 9 to move without affecting the transmission of vibration force too much.

[0027] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
