Description

Technical Field

[0001] This utility model relates to the field of unloading valve technology, specifically a tubular chain conveying unloading valve that facilitates unloading. Background Technology

[0002] The discharge valve of the tubular chain conveyor controls the discharge of materials from the conveying pipeline through rotation or swinging motion. With its high efficiency, precision and reliability, the discharge valve has become an indispensable piece of equipment in modern industrial production. Its application in environmental protection, chemical industry, food and other fields has demonstrated its wide adaptability and technical advantages.

[0003] Existing technology involves directly opening a discharge port on the pipeline. When material is conveyed to the opening, it is naturally discharged by gravity or air pressure difference. Although this achieves the basic discharge function, it has certain shortcomings: the discharge position is fixed and cannot be dynamically adjusted. If the discharge position needs to be changed, the pipeline needs to be re-drilled. In addition, the discharge port is often in a normally open state. When the material has not reached the designated position, leakage is likely to occur due to pipeline vibration, resulting in material waste. To address these issues, we provide a convenient pipe chain conveying discharge valve. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tubular chain conveying unloading valve that facilitates material unloading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tubular chain conveying unloading valve for easy material unloading, comprising a pipe, wherein a chain and chain plates are respectively driven and connected inside the pipe, and the outside of the chain is fixedly connected to the inside of the chain plates. The outer wall of the chain plates is in contact with the inner wall of the pipe. Two unloading frames are fixedly connected between the two pipes, and an unloading valve body is provided inside the unloading frame. The two ends of the unloading valve body are respectively rotatably connected to the inside of the two pipes. A valve is provided on the outer wall of the unloading valve body, and two rotating rods are fixedly connected to the two ends of the valves. One end of the two rotating rods is rotatably connected to the inside of the unloading valve body. A limiting mechanism is inserted into the inside of the rotating rod. A receiving block is fixedly connected to the outer wall of the unloading valve body, and the limiting mechanism is located inside the receiving block. A rotating mechanism is fixedly connected to the outer wall of the unloading valve body.

[0006] The aforementioned limiting mechanism includes a servo motor, a cam, a plug, a slide rod, a transmission block, and a spring. The output end of the servo motor is fixedly connected to the interior of the cam, and the cam is located on one side of the transmission block. One end of the plug is fixedly connected to one end of the slide rod, and the outer wall of the slide rod is fixedly connected to one end of the transmission block. One end of the slide rod is fixedly connected to one end of the spring.

[0007] As described above, the servo motor and the cam are both located inside the unloading valve body, the end of the insert block away from the slide rod is inserted into the inside of the rotating rod, and two guide blocks are fixedly connected to the outer wall of the slide rod.

[0008] As described above, the end of the guide block away from the slide rod is slidably connected to the inner wall of the receiving block, and the end of the spring away from the slide rod is fixedly connected to the inside of the receiving block.

[0009] The aforementioned rotating mechanism includes a second servo motor, a drive shaft, a first gear, and a second gear. The output end of the second servo motor is fixedly connected to one end of the drive shaft, and the outside of the drive shaft is fixedly connected to the inside of the first gear. The first gear meshes with the second gear.

[0010] As described above, the inner wall of the second gear is fixedly connected to the outer wall of the unloading valve body, and the inner wall of the unloading frame is fixedly connected to a mounting base.

[0011] As described above, the end of the drive shaft away from the servo motor is rotatably connected to the interior of the mounting base.

[0012] Compared with existing technologies, this easy-to-discharge tubular chain conveyor unloading valve has the following advantages:

[0013] I. This utility model, through the setting of a limiting mechanism, enables the controller to start a servo motor to drive the cam to rotate. When the cam's convex surface rotates to contact the transmission block, the transmission block is pressed and drives the slide rod to move. At this time, the spring is compressed, and the slide rod slides within the receiving block along the guide block's trajectory, ultimately synchronously driving the insert block to disengage from the rotating rod. Conversely, the insert block is inserted into the rotating rod to achieve locking. This can prevent the valve from accidentally opening due to material accumulation in the non-discharging state, avoiding automatic spillage of material and resulting waste. At the same time, combined with the design of the multi-point unloading valve body on the pipeline, material can be unloaded at any position, improving the flexibility and reliability of the equipment.

[0014] Second, this utility model uses a rotating mechanism to start a servo motor 2 via a controller, which drives the shaft to rotate and rotates gear 1. Through the meshing transmission between gear 1 and gear 2, gear 2 further drives the unloading valve body to rotate to the valve-down position. This effectively removes residual materials from the unloading valve body, reduces the risk of accumulation, and improves the cleanliness of unloading.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[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] like Figure 1-6 As shown, this utility model provides a technical solution: a tubular chain conveying unloading valve for easy material unloading, including a pipe 1, with a chain 2 and chain piece 3 respectively connected to the inside of the pipe 1, and the outside of the chain 2 is fixedly connected to the inside of the chain piece 3. The outer wall of the chain piece 3 is in contact with the inner wall of the pipe 1. Two unloading frames 4 are fixedly connected between the two pipes 1, and an unloading valve body 5 is provided inside the unloading frame 4. The two ends of the unloading valve body 5 are rotatably connected to the inside of the two pipes 1. A valve 6 is provided on the outer wall of the unloading valve body 5, and two rotating rods 7 are fixedly connected to the two ends of the valve 6. One end of the two rotating rods 7 is rotatably connected to the inside of the unloading valve body 5. A limiting mechanism 8 is inserted into the inside of the rotating rods 7. A receiving block 10 is fixedly connected to the outer wall of the unloading valve body 5, and the limiting mechanism 8 is located inside the receiving block 10. A rotating mechanism 9 is fixedly connected to the outer wall of the unloading valve body 5.

[0024] In use, first connect all electrical components to an external power source and then electrically connect them to the controller. Since a multi-point unloading valve body 5 is installed on pipeline 1, unloading can be achieved at any position. When a certain unloading valve body 5 needs to unload, the controller starts the rotating mechanism 9. The rotating mechanism 9 drives the unloading valve body 5 to rotate to the valve 6 facing downwards. This effectively removes residual material inside the unloading valve body 5, reduces the risk of accumulation, and improves the cleanliness of unloading. Subsequently, the controller starts the limiting mechanism 8. The limiting mechanism 8 slides along the trajectory of the guide block 11 in the receiving block 10. Finally, it synchronously drives the limiting mechanism 8 to disengage from the rotating rod 7. Conversely, the limiting mechanism 8 inserts into the rotating rod 7 to lock it. This can prevent the valve 6 from being accidentally opened due to material accumulation in the non-unloading state, and avoid the automatic spillage of material and waste. At the same time, combined with the design of the multi-point unloading valve body 5 on pipeline 1, material can be unloaded at any position, improving the flexibility and reliability of the equipment.

[0025] like Figure 1-5 As shown, the limiting mechanism 8 includes a servo motor 801, a cam 802, an insert block 803, a slide rod 804, a transmission block 805, and a spring 806. The output end of the servo motor 801 is fixedly connected to the inside of the cam 802, and the cam 802 is located on one side of the transmission block 805. One end of the insert block 803 is fixedly connected to one end of the slide rod 804, and the outer wall of the slide rod 804 is fixedly connected to one end of the transmission block 805. One end of the slide rod 804 is fixedly connected to one end of the spring 806. The servo motor 801 and the cam 802 are both located inside the unloading valve body 5. The end of the insert block 803 away from the slide rod 804 is inserted into the inside of the rotating rod 7. Two guide blocks 11 are fixedly connected to the outer wall of the slide rod 804. The end of the guide block 11 away from the slide rod 804 is slidably connected to the inner wall of the receiving block 10. The end of the spring 806 away from the slide rod 804 is fixedly connected to the inside of the receiving block 10.

[0026] The servo motor 801 is started by the controller, which drives the cam 802 to rotate. When the convex surface of the cam 802 rotates to contact the transmission block 805, the transmission block 805 is pressed and drives the slide rod 804 to move. At this time, the spring 806 is compressed, and the slide rod 804 slides in the receiving block 10 along the trajectory of the guide block 11. Finally, it synchronously drives the insert block 803 to disengage from the rotating rod 7. Conversely, the insert block 803 is inserted into the rotating rod 7 to achieve locking. This can prevent the valve 6 from being opened accidentally due to material accumulation in the non-discharging state, and avoid the waste caused by automatic material spillage. At the same time, combined with the design of the multi-point unloading valve body 5 on the pipeline 1, the material can be unloaded at any position, which improves the flexibility and reliability of the equipment.

[0027] The servo motor 801 is installed on the inner wall of the unloading valve body 5. The inner wall of the unloading valve body 5 has upward-facing heat dissipation holes to optimize the heat dissipation of the servo motor 801. At the same time, the heat dissipation holes are not connected to the inside of the material conveying channel, which can effectively prevent material leakage or blockage of the heat dissipation holes.

[0028] like Figure 1 and Figure 6 As shown, the rotating mechanism 9 includes a second servo motor 901, a drive shaft 902, a first gear 903, and a second gear 904. The output end of the second servo motor 901 is fixedly connected to one end of the drive shaft 902, and the outside of the drive shaft 902 is fixedly connected to the inside of the first gear 903. The first gear 903 meshes with the second gear 904. The inner wall of the second gear 904 is fixedly connected to the outer wall of the unloading valve body 5. The inner wall of the unloading frame 4 is fixedly connected to a mounting base 12. The end of the drive shaft 902 away from the second servo motor 901 is rotatably connected to the inside of the mounting base 12.

[0029] The servo motor 901 is started by the controller, and the drive shaft 902 rotates accordingly, which drives the gear 903 to rotate. With the meshing transmission of gear 903 and gear 904, gear 904 further drives the unloading valve body 5 to rotate to the valve 6 facing downward. This effectively removes residual materials in the unloading valve body 5, reduces the risk of accumulation and improves the cleanliness of unloading.

[0030] Working principle: In use, first connect all electrical components to an external power source and then electrically connect them to the controller. Since a multi-point unloading valve body 5 is installed on pipeline 1, unloading at any position is possible. When a particular unloading valve body 5 needs to unload, the controller starts the second servo motor 901, which drives the shaft 902 to rotate, thereby rotating the first gear 903. Through the meshing transmission between the first gear 903 and the second gear 904, the second gear 904 further rotates the unloading valve body 5 until the valve 6 faces the direction of unloading. In the next state, the controller then starts the servo motor 801, which drives the cam 802 to rotate. When the convex surface of the cam 802 rotates to contact the transmission block 805, the transmission block 805 is pressed and drives the slide rod 804 to move. At this time, the spring 806 is compressed, and the slide rod 804 slides in the receiving block 10 along the trajectory of the guide block 11. Finally, it synchronously drives the insert block 803 to disengage from the rotating rod 7. Conversely, the insert block 803 is inserted into the rotating rod 7 to achieve locking. This can prevent the valve 6 from being opened accidentally due to material accumulation in the non-unloading state.
