Description

Technical Field

[0001] This utility model relates to the field of electric tee technology, and in particular to a bias electric tee. Background Technology

[0002] In the grain storage industry, efficient and precise material transportation is crucial for ensuring smooth storage management processes and reducing operating costs. With the increasing scale and automation of the grain industry, higher demands are placed on the flexibility, adaptability, and reliability of material conveying equipment. Electric tees, as core reversing devices in grain conveying systems, are widely used at the junctions of various process equipment such as chutes, scraper conveyors, and bucket elevators. Their main function is to quickly switch material conveying paths according to production needs, realizing the diversion or merging of materials, playing a vital role in improving the overall operating efficiency of the grain storage conveying system.

[0003] Most electric tees used in existing technologies are positive-electric tees. Their overall working principle involves a motor providing power to drive a lead screw to rotate, while a nut that works with the lead screw converts this rotational motion into linear motion. The nut connects to a reversing valve core inside the tee. As the nut moves linearly, the reversing valve core slides within the tee housing, thereby changing the flow path of material within the tee and enabling rapid material reversal between the two outlets. This motor-lead screw-nut transmission-based structural design allows positive-electric tees to reversing material flow relatively stably, demonstrating good applicability in conventional installation scenarios.

[0004] However, when a positive-electric tee needs to connect to two pieces of equipment in the next process, and the installation location is directly above one of the process pieces, while the installation space is limited due to factors such as spatial layout, using existing positive-electric tees presents serious connection challenges. Due to the structural characteristics of positive-electric tees, their outlet position is relatively fixed. Within limited installation space, to ensure precise alignment between the positive-electric tee's outlet and the next process piece, the connection interface requires extensive customization and adjustment. This not only makes interface fabrication extremely difficult but also increases construction costs and extends the construction period, significantly hindering the process equipment modification work. Therefore, an offset-electric tee is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a biased electric tee, which aims to improve the problems in the prior art, such as the difficulty in manufacturing the equipment connection interface, high construction cost and long construction period due to limited installation space, as well as the easy damage to the flip plate after long-term use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrically driven tee includes a cabinet with two discharge ports at the bottom. One discharge port coincides with the central axis of the cabinet, while the other discharge port forms a 45° angle with the central axis. A flap is installed inside the cabinet, and a rotating assembly is installed on the outer wall of the flap. A slider is fixedly connected to one side of the flap, and a connecting shell is slidably connected to the outer wall of the slider. Limiting plates are fixedly connected to both sides of the slider, and the limiting plates are slidably connected to the surface of a sealing groove inside the connecting shell. A spring is installed inside the connecting shell, with its two ends fixedly connected to one side of the slider and one side of the inner wall of the connecting shell, respectively. A connecting frame is fixedly connected to the outer wall of the flap, and the connecting frame is slidably connected to the outer wall of the connecting shell. A triangular groove is provided on the inner wall of the cabinet to limit the rotation range of the flap.

[0009] The rotating assembly includes a second bearing, which is located on one side of the flap, and the outer wall of the second bearing is fixedly connected to one side of the connecting shell.

[0010] As a further description of the above technical solution:

[0011] One end of the bearing is rotatably connected to one side of the inner wall of the cabinet, and the other end of the bearing extends through to the outside of the cabinet.

[0022] This utility model has the following beneficial effects:

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-7This utility model provides an embodiment of a bias-driven tee, including a cabinet 1. The bottom of the cabinet 1 has two discharge ports. One discharge port coincides with the central axis of the cabinet 1, which is made of 304 stainless steel. The other discharge port forms a 45° angle with the central axis of the cabinet 1. These two specific angled discharge ports, combined with subsequent pipeline connections, effectively solve the problems of high manufacturing difficulty and high construction cost of the connection interface for downstream process equipment. Inside the cabinet 1 is a flap 22 made of wear-resistant manganese steel plate. This flap 22 serves as a core material guiding component, used to precisely control the flow direction of materials. A rotating assembly is provided on the outer wall of the flap 22. A slider 16 made of high-polymer wear-resistant nylon material is fixedly connected to one side of the flap 22. A connecting shell 18 is slidably connected to the outer wall of the slider 16. The slider 16, in conjunction with the connecting shell 18 and a spring 17, performs telescopic buffering movement, achieving the effect of reducing the impact force of materials on the surface of the flap 22, thereby extending the service life of the flap 22. Limiting plates 19 are fixedly connected to both sides of slider 16. The limiting plates 19 are slidably connected to the surface of the sealing groove inside the connecting shell 18. The limiting plates 19 are used to provide guidance and limit when slider 16 slides, ensuring the stability and reliability of the buffer mechanism. A high-strength compression spring 17 is set inside the connecting shell 18. The two ends of the spring 17 are fixedly connected to one side of slider 16 and one side of the inner wall of connecting shell 18, respectively. The spring 17 is used to absorb the impact energy generated when the material hits, and is the main functional component of the buffer component. A connecting frame 15 is fixedly connected to the outer wall of flip plate 22. The connecting frame 15 is slidably connected to the outer wall of connecting shell 18. The connecting frame 15 is used to protect the connecting shell 18 from dust and prevent material dust from entering the movement gap of slider 16 and affecting its buffering effect. A triangular groove is set on the inner wall of cabinet 1. The triangular groove is used to physically limit the rotation range of flip plate 22, so as to prevent flip plate 22 from hitting the inner wall of cabinet 1 or causing mechanical interference due to excessive rotation angle.

[0035] The rotating assembly includes a second bearing 8 of the deep groove ball bearing type. This rotating assembly provides power and support for the rotation of the flap 22, ensuring its precise switching of material outlets. The second bearing 8 is located on one side of the flap 22, and its outer side wall is fixedly connected to one side of the connecting shell 18. One end of the second bearing 8 is rotatably connected to one side of the inner wall of the cabinet 1, and the other end of the second bearing 8 extends through to the outside of the cabinet 1. This structure supports the entire weight of the flap 22 and its buffer mechanism, ensuring its smooth rotation with low frictional resistance. A first mounting base 6, a second mounting base 9, a third mounting base 20, and a limit switch 11 of model LXK3-20S / T are fixedly connected to one side of the cabinet 1. These mounting bases securely mount the entire drive and transmission components onto the cabinet 1, providing a foundation for stable operation of the equipment. The limit switch 11 detects the extreme position of the nut 3 and sends a signal to the control component to stop the motor 10, achieving... To prevent damage to the equipment caused by overtravel of the drive mechanism, bearing 28 is rotatably connected inside fixed seat 6. A T-shaped lead screw 2 is provided on one side of the cabinet 1. Both ends of the lead screw 2 are fixedly connected to bearing 4 of the thrust ball bearing type. Each bearing 4 is rotatably connected inside fixed seat 3 20. The bearing 4, together with fixed seat 3 20, fixes and supports the lead screw 2 axially and radially, achieving the effect of high-speed and stable rotation of the lead screw 2. A reinforcing rib 21 is fixedly connected to one side of fixed seat 29. The reinforcing rib 21 is used to enhance the structural strength and rigidity of the motor 10 mounting base and effectively suppress the vibration generated by the motor 10 during operation. A stepper motor 10 with a reducer is fixedly connected to one side of the reinforcing rib 21. The motor 10 serves as the power source of the entire device and provides driving force for the turning of the flip plate 22. The output end of the motor 10 is fixedly connected to the outer wall of one of the bearings 4. A bracket 5 is fixedly connected between the two fixed seats 3 20.

[0036] The outer wall of the T-shaped lead screw 2 is connected to a brass nut 3 via a threaded engagement. The lead screw 2 and the nut 3 rotate and move linearly, effectively converting the rotational motion output by the motor 10 into the linear motion of the nut 3, providing power input for the subsequent swing mechanism. A connecting rod 12 and a connecting strip 14 are fixedly connected to the outer wall of the nut 3. The connecting rod 12 is slidably connected between the two side brackets 5, guiding the sliding motion of the connecting rod 12 with the brackets 5. This prevents the nut 3 from rotating on the lead screw 2 and only performing purely linear reciprocating movement, ensuring precise transmission. For accuracy, a swing shaft 7 is fixedly connected to the outer wall of bearing 8, and a swing plate 13 is fixedly connected to the outer wall of swing shaft 7. A groove is opened inside swing plate 13. Swing shaft 7 is used to accurately transmit the swing of swing plate 13 to flip plate 22. It is the key hub connecting transmission mechanism and actuator. Connecting bar 14 is slidably connected to the surface of groove inside swing plate 13. Connecting bar 14 slides in cooperation with groove inside swing plate 13, which achieves the effect of cleverly converting linear motion of nut 3 into arc swing motion of swing plate 13, and finally drives flip plate 22 to complete the switching between two discharge ports.

[0037] Working Principle: During equipment use, the two outlets at the bottom of cabinet 1 are connected to the two devices in the next process. One outlet at the bottom of cabinet 1 is parallel and coincident with the central axis, while the other outlet forms a 45° angle with the central axis. This solves the problems of difficult manufacturing, high construction cost, and long construction period in existing technical solutions where the positive electric tee connects to the two devices in the next process and is located directly above one of the process devices. This enhances the convenience of installation, reduces construction costs, and shortens the construction period. Next, motor 10 is started, and the output end of motor 10 drives the lead screw 2 to rotate, causing bearing 4 to rotate inside the fixed seat 20. Since the lead screw 2 and the lead nut 3 are engaged, the lead screw 2 rotates while driving the lead nut 3, and the connecting rod 12 slides between the two side brackets 5, ensuring that the lead nut 3 does not rotate. While the lead nut 3 moves, it drives the connecting strip 14 to swing on the swing plate 1. 3. The sliding of the internal groove surface causes the swing shaft 7 and bearing 8 to rotate, thereby causing the flip plate 22 to rotate on the inner wall of the cabinet 1. The rotation of the flip plate 22 guides the material to one of the outlets at the bottom of the cabinet 1, while the other outlet remains closed. When the flip plate 22 forms a 45° angle with the central axis, the material collides with the surface of the flip plate 22, causing the slider 16 and the limiting plate 19 to slide inside the connecting shell 18, and the connecting frame 15 to slide on the outer wall of the connecting shell 18. The connecting frame 15 covers the connecting shell 18, preventing the material from entering the gap between the flip plate 22 and the connecting shell 18. The sliding of the limiting plate 19 inside the connecting shell 18 limits the movement direction of the slider 16, preventing the slider 16 from accidentally sliding out of the connecting shell 18. The sliding of the slider 16 inside the connecting shell 18 causes the spring 17 to compress, reducing the impact force of the material on the surface of the flip plate 22 and extending the service life of the components.
