The output end of the motor 52 is installed with a speed reducer 53. The output end of the speed reducer 53 is installed with a feeding rod 54. The bottom of the feeding box 51 is communicated with a feeding pipe 55.

[0028] As a technical optimization solution of the present utility model, by setting the transmission and feeding component 5, the motor 52 can be started during feeding, so that the output of the motor 52 drives the speed reducer 53 to rotate, and then drives the feeding rod 54 to rotate, enabling the hard gold powder to be quantitatively and uniformly conveyed from the feeding box 51 through the feeding pipe 55 into the gold melting furnace body 1. This mechanical transmission method is more stable and uniform in addition compared with manual feeding, and the addition amount can be accurately controlled by adjusting the speed of the motor 52 and other methods, effectively solving the problem of inaccurate measurement.

[0029] ReferringFigure 3 On one side of the blanking box 51, a cylinder 6 is installed. On the other side of the cylinder 6, a support plate 7 is installed. At the bottom of the support plate 7, a hydraulic cylinder 8 is installed, and the hydraulic cylinder 8 is installed on the top of the support base 2.

[0030] As a technical optimization scheme of the present utility model, by setting the cylinder 6, the support plate 7 and the hydraulic cylinder 8, the cylinder 6 can push the support plate 7 and the blanking box 51 to perform horizontal displacement, facilitating the adjustment of the blanking position.

The heat insulation box 10 protects the hydraulic cylinder 8, reducing the influence of the heat of the melting furnace on the hydraulic cylinder 8, preventing the hydraulic cylinder 8 from being damaged due to high temperature, extending its service life, and ensuring the stability of the equipment operation.

[0033] Reference Figure 3 On the top of the inner wall of the blanking box 51, a limiting plate 11 is installed. The limiting plate 11 is located at the bottom of the speed reducer 53. Inside the limiting plate 11, a limiting ring 12 is movably connected. Inside the limiting ring 12, it is installed on the outside of the feeding rod 54.

[0034] As a technical optimization scheme of the present utility model, by setting the limiting plate 11 and the limiting ring 12, the limiting plate 11 can perform movable limiting on the surface of the limiting ring 12, enabling the limiting ring 12 to play a supporting and positioning role on the feeding rod 54, keeping the feeding rod 54 stable during rotation, ensuring the smoothness of the hard gold powder transportation, and avoiding uneven addition of hard gold powder caused by the shaking of the feeding rod 54.

[0038] As a technical optimization scheme of the present utility model, by setting the heat insulation protection box 15, heat insulation protection is carried out on the cylinder 6, reducing the influence of the high temperature of the melting furnace on the cylinder 6, preventing the cylinder 6 from malfunctioning due to excessive temperature, ensuring the stable operation of the cylinder 6, and further ensuring the normal operation of the position adjustment function of the blanking box 51.

[0039] The working principle and usage process of the present utility model: When using the gold melting furnace convenient for adding hard gold powder, first put the gold into the gold melting furnace body 1 for heating and melting. At this time, the thermocouple sensor 42 in the detection and control component 4 installed on one side of the inner wall of the gold melting furnace body 1 starts to work. It will monitor the temperature in the furnace in real time and transmit the temperature signal to the controller 43 through a wire. When the gold gradually melts and the thermocouple sensor 42 detects that the temperature in the furnace reaches the preset temperature value suitable for adding hard gold powder, the controller 43 receives this temperature signal and accurately controls the time relay 44 electrically connected thereto according to the preset program. The time relay 44 starts to work, sends a signal to start the motor 52, and the motor 52 starts to rotate after receiving the start signal. The output shaft of the motor 52 drives the reducer 53 to rotate. After the reducer 53 further reduces the speed and increases the torque, it drives the feeding rod 54 to rotate. The hard gold powder previously loaded into the blanking box 51 through the feeding hopper 9 is quantitatively and uniformly conveyed from the blanking pipe 55 communicated with the bottom of the blanking box 51 into the gold melting furnace body 1. During the process of adding hard gold powder, if it is necessary to adjust the blanking position, the cylinder 6 can be started, and the cylinder 6 pushes the support plate 7 and the blanking box 51 connected thereto to perform a horizontal displacement. If it is necessary to adjust the height of the blanking box 51, the hydraulic cylinder 8 is started, and the hydraulic cylinder 8 drives the support plate 7 and the blanking box 51 to rise or fall. Through the cooperation of the cylinder 6 and the hydraulic cylinder 8, the blanking pipe 55 can be accurately aligned with the feeding port of the gold melting furnace body 1, ensuring the smooth addition of hard gold powder and avoiding spilling, achieving the effect of being convenient for adding hard gold powder, and enhancing the production efficiency and product quality of the gold melting furnace.

[0040] In summary: For the gold melting furnace convenient for adding hard gold powder, by setting the detection and control component 4 to cooperate with the transmission blanking component 5 to conveniently add hard gold powder into the gold melting furnace body 1, it solves the problems that the existing gold melting furnace lacks a special hard gold powder adding device, requires manual feeding during shutdown when adding, resulting in uneven mixing and inaccurate metering, and the operation is cumbersome and time-consuming, affecting the production efficiency and product quality of the gold melting furnace.
