Description

Technical Field

[0001] The utility model relates to the technical field of tungsten-molybdenum materials, in particular to a feeding hopper for stirring and connecting tungsten-molybdenum materials. Background Art

[0002] Tungsten and molybdenum materials are high-temperature metals with good thermal conductivity, electrical conductivity, low thermal expansion coefficient, high-temperature strength, low vapor pressure and wear resistance. They are important materials for electronic and power equipment manufacturing, metal material processing, glass manufacturing, high-temperature furnace structural component manufacturing, aerospace and defense industry applications.

[0003] The Chinese patent discloses a feed hopper (CN202987940U), including a hopper, a motor and a lifting and stirring mechanism connected to the motor. A feed port is provided at the top of the hopper, and the motor is arranged at the feed port; a discharge port is provided at the bottom of the hopper, and the discharge port is larger than the feed port; the lifting and stirring mechanism includes a pipe column and a barb movably connected to the pipe column. Compared with the traditional hopper design that is wide at the top and narrow at the bottom, the utility model is designed to be narrow at the top and wide at the bottom, thereby preventing the fuel from being squeezed by the four side walls at the discharge port and being stuck at the discharge port; a lifting and stirring mechanism is added, and the motor is in continuous operation to drive the pipe column on the lifting and stirring mechanism to move up and down, and the barb movably connected to the pipe column swings up and down accordingly. When moving downward, the barb closes toward the pipe column due to inertia, and when moving upward, the barb opens away from the pipe column due to gravity. Such repeated swinging can destroy the structure of the stuck fuel and prevent it from clogging the hopper. At present, most of the feed rates are carried out by the weight of the object itself. On the one hand, the discharge is uneven and clogging is easy to occur. On the other hand, adhesion is easy to occur on the inner wall of the feed hopper, and the interior of the feed hopper is easy to corrode for a long time. Therefore, a feed hopper for stirring and connecting tungsten-molybdenum materials is provided. Utility Model Content

When the half gear loses meshing with the transmission rack, the transmission rack drives the impact rod to impact the inner wall of the feed hopper under the action of the telescopic spring. The feed hopper is vibrated by the impact, so as to avoid the adhesion of tungsten-molybdenum material to the feed hopper, resulting in a decrease in feed content and an increase in the discharge amount of the feed hopper. At the same time, it can also avoid the corrosion of the feed hopper due to adhesion of tungsten-molybdenum material, thereby increasing the service life of the feed hopper and accelerating the discharge efficiency of the feed hopper.

[0014] 2. In the utility model, a dredging component is provided. Under the action of the thread of the reciprocating screw, the fixed plate drives the scraper ring to move up and down in the feed hopper. The up and down movement of the scraper ring can stir the tungsten-molybdenum material. The rotation of the reciprocating screw will also drive the spiral rod to rotate. When discharging, not only can the material be discharged evenly, but also the blockage of the feed hopper can be avoided, thereby improving the stability of the feed hopper.

[0022] like Figure 1-4 As shown: This embodiment provides a feeding hopper for stirring and joining tungsten and molybdenum materials, comprising a feeding hopper 1, a fixing cylinder 4 is fixedly installed on the inner wall of the feeding hopper 1, a mounting cover 5 is fixedly installed on the upper surface of the fixing cylinder 4, a supporting frame 2 is fixedly installed on the outer surface of the feeding hopper 1, a vibration component 7 is arranged on the inner wall of the fixing cylinder 4, and a dredging component 6 is arranged on the inner wall of the mounting cover 5;

[0023] The vibration assembly 7 includes a positioning plate 71 and a connecting rod 76, a telescopic spring 72 is fixedly installed on the side wall of the positioning plate 71, a transmission rack 73 is fixedly installed on one end of the telescopic spring 72, a strike rod 74 is fixedly installed on one end of the transmission rack 73, a half gear 75 is fixedly installed on the outer surface of the connecting rod 76, the lower surface of the positioning plate 71 is fixedly connected to the inner wall of the bottom surface of the fixed cylinder 4, the outer surface of the connecting rod 76 is rotatably connected to the inner wall of the shell cavity of the fixed cylinder 4, the half gear 75 is meshed with the transmission rack 73, one end of the strike rod 74 is in contact with the inner wall of the feed hopper 1, one end of the connecting rod 76 extends to the upper surface of the fixed cylinder 4, and the other end of the connecting rod 76 extends to the outside of the lower surface of the fixed cylinder 4.

[0024] The specific implementation method is as follows: pour the tungsten-molybdenum material into the feed hopper 1, and the driving motor 61 in the mounting cover 5 drives the connecting rod 76 to rotate. At this time, the connecting rod 76 drives the half gear 75 to rotate in the fixed cylinder 4. When the half gear 75 is engaged with the transmission rack 73, the rotation of the half gear 75 will drive the transmission rack 73 to move, thereby driving the impact rod 74 to move back. At this time, the telescopic spring 72 is in a compressed state. When the half gear 75 loses engagement with the transmission rack 73, the transmission rack 73 drives the impact rod 74 to impact the feed hopper 1 under the action of the telescopic spring 72. At this time, the inner wall of the feed hopper 1 vibrates, and the tungsten-molybdenum material is shaken off, thereby improving the discharge efficiency of the feed hopper.

[0025] The dredging component 6 includes a driving motor 61, the upper surface of the driving motor 61 is fixedly connected to the inner wall of the top surface of the mounting cover 5, the output end of the driving motor 61 is fixedly connected to one end of a connecting rod 76, the other end of the connecting rod 76 is fixedly installed with a reciprocating screw 62, the outer surface of the reciprocating screw 62 is threadedly installed with a fixing plate 63, the outer surface of the fixing plate 63 is fixedly installed with a scraper ring 64, the outer surface of the scraper ring 64 is in contact with the inner wall of the feed hopper 1, one end of the reciprocating screw 62 is fixedly installed with a spiral rod 65, the lower surface of the feed hopper 1 is connected and installed with a discharge pipe 3, and one end of the spiral rod 65 extends to the inside of the discharge pipe 3.

[0026] The specific implementation method is as follows: when the connecting rod 76 rotates, it will also drive the reciprocating screw 62 to rotate. As the reciprocating screw 62 rotates, the fixed plate 63 moves up and down on the outer surface of the reciprocating screw 62 under the action of the thread on the outer surface, thereby driving the scraper ring 64 to move up and down in the feed hopper 1. The scraper ring 64 cleans the inner wall of the feed hopper 1 and can also stir the tungsten-molybdenum material to avoid adhesion. When the reciprocating screw 62 rotates, it will drive the spiral rod 65 to rotate in the discharge pipe 3, and then open the control valve on the discharge pipe 3, and the tungsten-molybdenum material in the feed hopper 1 is discharged from the discharge pipe 3.

[0027] Working principle: Pour tungsten-molybdenum material into the feed hopper 1, and the drive motor 61 in the mounting cover 5 drives the connecting rod 76 to rotate. At this time, the connecting rod 76 drives the half gear 75 to rotate in the fixed cylinder 4. When the half gear 75 is engaged with the transmission rack 73, the rotation of the half gear 75 will drive the transmission rack 73 to move, thereby driving the impact rod 74 to move back. At this time, the telescopic spring 72 is in a compressed state. When the half gear 75 loses engagement with the transmission rack 73, the transmission rack 73 drives the impact rod 74 to the feed material under the action of the telescopic spring 72. The hopper 1 is hit, and the inner wall of the feed hopper 1 vibrates. When the connecting rod 76 rotates, it also drives the reciprocating screw 62 to rotate. As the reciprocating screw 62 rotates, the fixing plate 63 moves up and down on the outer surface of the reciprocating screw 62 under the action of the thread on the outer surface, thereby driving the scraper ring 64 to move up and down in the feed hopper 1. The scraper ring 64 cleans the inner wall of the feed hopper 1. When the reciprocating screw 62 rotates, it drives the screw rod 65 to rotate in the discharge pipe 3, and then opens the control valve on the discharge pipe 3, and the tungsten-molybdenum material in the feed hopper 1 is discharged from the discharge pipe 3.
