Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] An automatic feeding device for refractory material production includes a mixing barrel 1 and a feeding pipe 2, the feeding pipe 2 is fixedly connected to the bottom of the mixing barrel 1, a lower hopper 3 is arranged at the bottom of the feeding pipe 2, the lower hopper 3 is hinged to the feeding pipe 2 at the connection point through a rotating shaft, a bracket 4 is fixedly connected to one side of the feeding pipe 2, a motor 5 is fixedly installed on one side of the bracket 4, the output end of the motor 5 passes through the inside of the feeding pipe 2 and is fixedly connected to a spiral rod 6, a swing mechanism is arranged at the bottom of one side of the feeding pipe 2, and a blowing mechanism is arranged on one side of the swing mechanism.

[0029] The swing mechanism includes a connecting frame 7 fixedly connected to the bottom of the feeding pipe 2, a first transmission wheel 8 is sleeved on the surface of the output end of the motor 5, the first transmission wheel 8 is connected to the second transmission wheel 9 through a belt drive, a screw rod 10 is fixedly connected to one side of the second transmission wheel 9, and a moving block 11 is transmission-connected to the surface of the screw rod 10, a swing block 12 is fixedly connected to the bottom of the lower hopper 3, and the moving block 11 and the swing block 12 are hinged at the connection through a connecting rod 13.

[0030] In this embodiment, it is considered that when the automatic feeding device is transporting, the refractory material will finally be discharged from the feeding pipe 2 and pass through the lower hopper 3. During the process of the refractory material falling in the lower hopper 3, it can easily cause the refractory material to accumulate on the lower hopper 3, resulting in ineffective material discharge, which affects the feeding rate of the automatic feeding device. Therefore, by setting a swing mechanism, the motor 5 can be started to rotate, driving the screw rod 6 to rotate to transmit the refractory material in the feeding pipe 2, so that the refractory material falls on the lower hopper 3. At the same time, the motor 5 will also drive the first transmission The driving wheel 8 rotates, and the first transmission wheel 8 drives the second transmission wheel 9 to rotate through the belt. The second belt pulley drives the screw rod 10 to rotate. When the screw rod 10 rotates, it will drive the moving block 11 to make the moving block 11 reciprocate along the trajectory of the sliding block 24 and the sliding groove 25, and at the same time drive the connecting rod 13 to make appropriate adjustments around the hinge. The connecting rod 13 will drive the swing block 12 and the lower hopper 3 to swing back and forth around the hinge between the feeding pipe 2 and the lower hopper 3, thereby improving the fluidity of the refractory material, avoiding the accumulation of refractory materials, and affecting the feeding rate of the automatic feeding device.

[0031] The problem that, when the automatic feeding device is used for conveying, the refractory material will finally be discharged from the feeding pipe 2 and pass through the lower hopper 3, and the refractory material will only slide down due to the gravity of the refractory material itself during the process of falling in the lower hopper 3 can easily cause the refractory material to accumulate on the lower hopper 3, resulting in ineffective feeding and affecting the feeding rate of the automatic feeding device is solved.

[0032] A sliding block 24 is fixedly connected to the top of the moving block 11 , and a sliding groove 25 for use with the sliding block 24 is formed on the inner wall of the connecting frame 7 .

[0033] In this embodiment, by providing the sliding block 24 and the sliding groove 25, when the screw rod 10 rotates to transmit the moving block 11, the moving block 11 is restricted to move only along the track of the sliding block 24 and the sliding groove 25, while improving its stability during movement.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, the swing mechanism in this embodiment can swing the lower hopper 3, thereby increasing the falling rate of the refractory material. However, considering that some fine refractory materials will adhere to the lower hopper 3, they cannot be dropped by swinging only, which will also affect the feeding rate. In this application, the blast mechanism includes an air collecting box 14 fixedly connected to the bottom of the connecting frame 7, one side of the air collecting box 14 is fixedly connected to an air inlet pipe 15, both sides of the air collecting box 14 are fixedly connected to an injection pipe 16, and one end of the injection pipe 16 is fixedly connected to an injection hood 17;

[0036] A push rod 18 is fixedly connected to one side of the moving block 11 . One end of the push rod 18 penetrates into the interior of the air collecting box 14 and is fixedly connected to a push block 19 .

[0037] In this embodiment, it is considered that some fine refractory materials may adhere to the lower hopper 3 and cannot be dropped by swinging only, which will also affect the feeding rate. Therefore, by setting a blast mechanism, the blast mechanism can be set to move the moving block 11 back and forth while the moving block 11 moves back and forth. Figure 2 and Figure 3 When the moving block 11 moves to the right, it will drive the push rod 18, the push block 19 and the piston 20 to move to the right. The piston 20 will squeeze the gas in the gas collecting box 14. When the pressure is greater than the limit of the one-way pressure valve 22, the gas will be ejected from the jet pipe 16 and then sprayed on the lower hopper 3 through the jet cover 17, blowing off the fine refractory materials, further improving the feeding rate of the automatic feeding device;

[0038] The problem that some fine refractory materials may adhere to the lower hopper 3 and cannot be dropped by swinging alone, which may also affect the feeding rate, is solved;

[0039] It should be noted that when the moving block 11 is reset, it will drive the push rod 18, the push block 19 and the piston 20 to reset. At this time, there is a negative pressure in the air collecting box 14, and the gas will enter the air collecting box 14 through the air inlet pipe 15 to supplement the air source, thereby circulating and spraying the gas onto the lower hopper 3.

[0040] A piston 20 is fixedly connected to one side of the push block 19 , and the piston 20 is made of rubber.

[0041] In this embodiment, by providing the piston 20 , a closed cavity can be formed in the gas collecting box 14 . When the push block 19 drives the piston 20 to move, the gas in the gas collecting box 14 is compressed.

[0042] A one-way valve 21 is fixedly connected to the surface of the air inlet pipe 15 , and a one-way pressure valve 22 is fixedly installed on the surface of the air injection pipe 16 .

[0043] In this embodiment, a one-way valve 21 and a one-way pressure valve 22 are provided, wherein the one-way valve 21 is a valve that can only take air into the air collecting box 14, and the one-way pressure valve 22 is a valve that can only exhaust air into the jet pipe 16. Therefore, the compressed gas in the air collecting box 14 will be ejected through the jet pipe 16, and the air collecting box 14 will be under negative pressure, and external gas will enter the interior of the air collecting box 14 through the air intake pipe 15.

[0044] The connection between the air injection pipe 16 and the feeding pipe 2 is supported by a support block 23 .

[0045] In this embodiment, the support block 23 is provided to support the jet pipe 16 and limit the position of the jet pipe 16, so that the jet pipe 16 is more stable during the jetting process.

[0046] Working principle: the user starts the motor 5 to rotate, driving the screw rod 6 to rotate and transmit the refractory material in the feeding tube 2, so that the refractory material falls on the lower hopper 3. At the same time, the motor 5 will also drive the first transmission wheel 8 to rotate, and the first transmission wheel 8 drives the second transmission wheel 9 to rotate through the belt, and the second belt pulley will drive the screw rod 10 to rotate. When the screw rod 10 rotates, it will drive the moving block 11 to move back and forth along the trajectory of the sliding block 24 and the sliding groove 25, and at the same time drive the connecting rod 13 to make appropriate adjustments around the hinge, and the connecting rod 13 will drive the swing block 12 and the lower hopper 3 to swing back and forth around the hinge between the feeding tube 2 and the lower hopper 3, thereby improving the fluidity of the refractory material, avoiding the accumulation of refractory materials, and affecting the feeding rate of the automatic feeding device;

[0047] While the moving block 11 is moving back and forth, Figure 2 and Figure 3 When the moving block 11 moves to the right, it will drive the push rod 18, the push block 19 and the piston 20 to move to the right. The piston 20 will squeeze the gas in the gas collecting box 14. When the pressure is greater than the limit of the one-way pressure valve 22, the gas will be ejected from the injection pipe 16 and then sprayed on the lower hopper 3 through the injection hood 17, blowing off the fine refractory materials, further improving the feeding rate of the automatic feeding device.
