[0002] Instrument transformers are electrical devices that are mainly used in power systems to convert high voltage or large current into low voltage or small current for measurement, protection and control. They play a vital role in power systems because directly measuring high voltage or large current is both dangerous and inaccurate. Instrument transformers can isolate the measuring equipment from high voltage or large current and provide a safe working environment.

Traditional pouring equipment often has low pouring efficiency, serious material waste, and it is difficult to accurately control the pouring amount and direction. In addition, bubbles and uneven pouring are prone to occur during the pouring process, affecting the quality of the final product. The existing pouring hopper needs to add and adjust the casting material many times during the pouring process, which increases the workload and may introduce bubbles and impurities. At the same time, these devices are also inconvenient in cleaning and maintenance, and it is easy for the casting material to remain on the inner wall, affecting the smooth progress of subsequent production.

The hopper can be installed on the pouring equipment through the outer end of the bearing rod, and the inclination angle of the hopper can be adjusted by rotating the axial rod on the bearing rod, thereby controlling the pouring direction of the hopper, so that the hopper can realize multi-directional pouring. After the pouring angle is adjusted, the outer material tube can be pushed to rotate on the inner material tube through the adjusting groove. Since the outer surface of the inner material tube is provided with a slide groove, a slider is provided in the slide groove, and the slider is fixedly connected to the bottom inner surface of the outer material tube, the outer material tube will also move upward relative to the inner material tube as the outer material tube rotates, thereby realizing the adjustment of the internal cavity of the inner material tube, controlling the size of the internal cavity of the inner material tube, and injecting the casting material into the hopper through the feeding pipe on the top cover.

One end of the elastic tube away from the buffer plate is fixedly connected to the two side surfaces of the scraper. When the motor starts to drive the rotating rod to rotate, it will also drive the mounting block to rotate, thereby prompting the mounting block to drive the scraper strip to rotate on the inner wall of the inner material tube through the first connecting rod and the second connecting rod.

When the outer material tube moves downward to extrude and pour the pouring material inside the inner material tube, as the pouring material is collectively squeezed in the inner material tube, the pouring material first generates an extrusion force on the pressure plate, thereby prompting the pressure plate to move downward in the inner material tube, and as the pouring material continues to be squeezed, the pouring material will enter the cavity between the pressure plate and the bottom plate through the leakage hole on the pressure plate and finally complete the pouring through the pouring tube.

[0017] The present invention provides an angle-adjustable pouring hopper for mutual inductor processing, which has the following beneficial effects:

[0018] 1. The angle-adjustable pouring hopper processed by the mutual inductor controls the internal cavity of the inner material tube to match according to the pouring amount required for each pouring production, so as to achieve accurate delivery of the pouring material and avoid the problem of adding the pouring material multiple times during the pouring process, which not only increases the workload but also affects the quality and efficiency of the pouring. When pouring, the motor can be started, and the start of the motor will drive the rotating rod to rotate, that is, the threaded rod in the rotating rod will rotate, and the top thread of the threaded rod is connected with a driving tube, and the driving rod is fixedly connected to the inner material tube through the support rod, so the rotation of the rotating rod will also cause the threaded rod to move down along the rotating rod, thereby driving the top cover to rotate and move down. The downward movement will generate a downward pulling force on the outer material tube, thereby causing the outer material tube to rotate and move downward on the outer surface of the inner material tube, and squeeze the internal cavity of the inner material tube, causing the castable in the inner material tube to be injected into the mold through the pouring pipe on the chassis to achieve pouring. By setting up the outer material tube and connecting the outer material tube to the motor through a threaded rod and a rotating rod, pouring can be achieved by pressurized transportation. Compared with the commonly used natural flow pouring, not only the pouring speed can be greatly improved, but also the pouring quality is greatly improved. The castable on the inner wall of the outer material tube can be cleaned by moving the outer material tube up and down, avoiding the problem of difficulty in moving due to the castable remaining on the inner wall of the outer material tube not being cleaned in time.

[0019] 2. The angle-adjustable pouring hopper processed by the mutual inductor can scrape the inner wall of the inner material tube by rotating the scraper bar, so as to avoid the problem that the stubborn pouring material sticking to the inner surface of the inner material tube cannot be effectively cleaned. At the same time, the pouring material inside the inner material tube can be stirred by the staggered first connecting rod and the second connecting rod, so that the pouring material inside the inner material tube is in a flowing state, which can ensure the fluidity of the pouring material and avoid local enrichment or deficiency, thereby ensuring the uniformity of the pouring material and the performance of the final solidified product. In addition, the bubbles in the pouring material can be effectively removed by stirring, the pores in the product after pouring can be reduced, and the mechanical strength and electrical insulation performance of the product can be improved. Stirring the pouring material can also help improve the efficiency of the pouring production line, ensure the fluidity of the material and the continuity of pouring, and reduce the downtime in production. At the same time, when the scraper bar rotates, The scraper is driven to rotate, thereby scraping and cleaning the upper surface of the inner material tube through the scraper, and the limit ring and the buffer plate will also rotate when the scraper rotates, and the buffer plate and the scraper are connected by an elastic tube. Therefore, when there is stubborn castable adhesion on the inclined surface of the inner material tube, as the scraper rotates, the buffer plate will first contact the stubborn castable, and as the rotation amplitude increases, the pressure between the buffer plate and the stubborn castable increases. At this time, the buffer plate will squeeze the elastic tube, and the pressure between the buffer plate and the stubborn castable gradually increases. In this way, the squeezing force on the stubborn castable can be gradually increased, so that there is a buffer force when scraping the stubborn castable, avoiding direct rigid scraping and causing deformation of the scraper and the scraper, which can not only clean the stubborn castable, but also greatly improve the working stability of the hopper.

[0020] 3. The angle-adjustable pouring hopper processed by the mutual inductor, when the motor stops, the pressure on the pouring material in the inner material tube stops, and the pressure plate is reset under the action of elastic force, so that the space between the pressure plate and the chassis gradually increases, that is, the cavity between the pressure plate and the chassis is sucked in both directions through the leakage hole and the pouring tube, thereby generating a reverse suction force on the pouring tube, thereby generating a reverse suction force on the pouring material remaining in the pouring tube, thereby avoiding the problem of pouring material dripping through the pouring tube during the pouring interval, which can not only avoid the waste of pouring material, but also avoid pollution to the pouring equipment.

Six telescopic rods 77 are arranged at fixed intervals around the central axis of the outer material tube 71. A fixed seat 78 is fixedly connected to the bottom of the telescopic rod 77. An annular groove 79 is horizontally opened on the outer surface of the bottom of the inner material tube 1. The inner end of the fixed seat 78 is slidably connected in the annular groove 79.

[0037] A motor 710 is fixedly installed on the middle bottom surface of the chassis 2, and the output end of the motor 710 is rotatably connected to a rotating rod 711. The rotating rod 711 passes through the chassis 2 and is arranged inside the inner material tube 1. A socket hole 712 is provided on the upper surface of the rotating rod 711, and a threaded rod 713 is slidably connected to the socket hole 712 up and down.

[0038] The top surface of the inner material tube 1 is arranged to be inclined, and the edge of the top surface of the inner material tube 1 is symmetrically fixedly connected with a support rod 715, and one end of the support rod 715 away from the inner material tube 1 is fixedly connected with a drive tube 716, and the drive tube 716 is arranged above the rotating rod 711, and the inner surface of the drive tube 716 is threadedly connected to the top outer surface of the threaded rod 713.

[0039] During operation, the hopper can be mounted on the pouring equipment through the outer end of the bearing rod 6. The tilt angle of the hopper can be adjusted by rotating the axial rod 5 on the bearing rod 6, thereby controlling the pouring direction of the hopper, so that the hopper can achieve multi-directional pouring. After the pouring angle is adjusted, the outer material tube 71 can be pushed to rotate on the inner material tube 1 through the adjusting groove 74. Since the outer surface of the inner material tube 1 is provided with a slide groove 72, a slider 73 is provided in the slide groove 72, and the slider 73 is fixedly connected to the inner surface of the bottom of the outer material tube 71, the outer material tube 71 rotates with the rotation of the outer material tube 71. 71 will also move upward relative to the inner material tube 1, so as to adjust the internal cavity of the inner material tube 1, control the size of the internal cavity of the inner material tube 1, and inject the casting material through the feeding pipe 76 on the top cover 75, so as to control the internal cavity of the inner material tube 1 according to the casting amount required for each casting production to match, realize the accurate delivery of the casting material, avoid the problem of adding the casting material multiple times during the casting process, which not only increases the workload, but also affects the quality and efficiency of the casting.

Therefore, the rotation of the rotating rod 711 will also cause the threaded rod 713 to move downward along the rotating rod 711, thereby driving the top cover 75 to rotate and move downward.

The casting material on the inner wall of the outer material pipe 71 can be cleaned by moving the outer material pipe 71 up and down, avoiding the problem of difficulty in movement caused by the casting material remaining on the inner wall of the outer material pipe 71 not being cleaned in time.

[0040] Second embodiment: Figures 1 to 8 As shown, the auxiliary mechanism 8 includes a mounting block 81, which passes through and is fixedly connected to the middle outer surface of the rotating rod 711. The mounting block 81 is arranged in a wheel shape, and a scraper bar 82 is fitted on the inner surface of the inner material tube 1. The scraper bar 82 is arranged in an inclined shape. The top of the scraper bar 82 is fixedly connected to a first connecting rod 83, and the bottom of the scraper bar 82 is fixedly connected to a second connecting rod 84. The end of the first connecting rod 83 away from the scraper bar 82 is fixedly connected to the upper surface edge of the mounting block 81, and the end of the second connecting rod 84 away from the scraper bar 82 is fixedly connected to the lower surface edge of the mounting block 81.

[0041] Three scraper strips 82 are arranged at fixed intervals around the central axis of the mounting block 81, and a scraper plate 85 is fixedly connected to the top of the three scraper strips 82. The bottom surface of the scraper plate 85 is fitted on the top surface of the inner material tube 1, and the outer surface of the scraper plate 85 is penetrated and fixedly connected with a limiting ring 86.

The inner wall of the inner material tube 1 is scraped by the rotation of the scraper bar 82 to avoid the problem that the stubborn casting material adhering to the inner surface of the inner material tube 1 cannot be effectively cleaned. At the same time, the casting material inside the inner material tube 1 can be stirred by the staggered first connecting rod 83 and the second connecting rod 84, so that the casting material inside the inner material tube 1 is in a flowing state, which can ensure the fluidity of the casting material and avoid local enrichment or deficiency, thereby ensuring the uniformity of the casting material and the performance of the final cured product. In addition, the stirring can effectively remove bubbles in the casting material, reduce the pores in the product after casting, and improve the mechanical strength and electrical insulation performance of the product. Stirring the casting material also helps to improve the efficiency of the casting production line, ensure the fluidity of the material and the continuity of casting, and reduce The scraper 82 rotates to drive the scraper 85 to rotate, so that the upper surface of the inner material tube 1 is scraped and cleaned by the scraper 85, and the limit ring 86 and the buffer plate 87 rotate when the scraper 85 rotates, and the buffer plate 87 and the scraper 85 are connected by an elastic tube 88. Therefore, when there is stubborn castable material adhering to the inclined surface of the inner material tube 1, the scraper 82 rotates to make the buffer plate 87 contact with the stubborn castable first, and as the rotation amplitude increases, the buffer plate 87 is The pressure between the plate 87 and the stubborn castable increases, and the buffer plate 87 squeezes the elastic tube 88. At this time, the pressure between the buffer plate 87 and the stubborn castable gradually increases. In this way, the squeezing force on the stubborn castable can be gradually increased, so that there is a buffer force when scraping the stubborn castable, avoiding direct rigid scraping that causes deformation of the scraper 85 and the scraper strip 82. Not only can the stubborn castable be cleaned, but also the working stability of the hopper is greatly improved.

[0044] The third embodiment: Figures 1 to 8 As shown, a pressure plate 89 is slidably connected to the inner surface of the bottom of the inner material tube 1, and leakage holes 810 are evenly penetrated through the upper surface of the pressure plate 89. The middle part of the pressure plate 89 is slidably sleeved on the bottom outer surface of the rotating rod 711, and a connecting ring 811 is fixedly connected to the middle upper surface of the pressure plate 89.

The top of the reset cover 812 is rotatably connected to the outer surface of the rotating rod 711, and the bottom of the reset cover 812 is elastically connected to the upper surface of the pressure plate 89 through a spring. A cavity is reserved between the pressure plate 89 and the chassis 2, and a spiral plate 813 is fixedly connected to the inside of the pouring tube 3.

[0045] During operation, when the outer material tube 71 moves downward to squeeze and pour the casting material inside the inner material tube 1, as the casting material is collectively squeezed in the inner material tube 1, the casting material first generates an extrusion force on the pressure plate 89, thereby prompting the pressure plate 89 to move downward in the inner material tube 1. As the casting material continues to be squeezed, the casting material will enter the cavity between the pressure plate 89 and the bottom plate 2 through the leakage hole 810 on the pressure plate 89 and finally complete the pouring through the pouring tube 3. When the motor 710 stops, the pressure on the casting material in the inner material tube 1 stops. At this time, the pressure plate 89 is reset under the action of elastic force, so that the space between the pressure plate 89 and the chassis 2 is gradually increased, that is, the cavity between the pressure plate 89 and the chassis 2 is sucked in both directions through the leakage hole 810 and the pouring tube 3, thereby generating a reverse suction force on the pouring tube 3, thereby generating a reverse suction force on the castable material remaining in the pouring tube 3, thereby avoiding the problem of the castable material dripping through the pouring tube 3 during the pouring interval, which can not only avoid the waste of castable material, but also avoid pollution to the pouring equipment.
