[0035] The horizontal moving assembly and the long hole 26 are arranged on the U-shaped frame 2;

[0036] The feeding box 3 with an open bottom is connected to a horizontal moving assembly and the feeding box 3 moves along the long hole 26 and slides with the U-shaped frame 2;

[0037] The feed port 31 is provided on the rear side wall of the feeding box 3 and is connected to the output end of a powder delivery pump fixedly provided in another area through a hose, and the input end of the powder delivery pump is connected to the sintering machine head ash storage bin fixedly provided on one side thereof;

[0038] The star-shaped feeder 4 is arranged at the bottom of the feeding box 3 and is connected with the interior thereof.

[0039] Further refinement of the embodiment of the present invention, such as Figure 1 As shown, the horizontal moving assembly includes a multi-stage electric push rod 21 and a multi-stage telescopic rod 22 , and the U-shaped frame 2 is provided with the multi-stage electric push rod 21 and the multi-stage telescopic rod 22 connected to the feeding box 3 .

[0040] Further refinement of the embodiment of the present invention, such as Figure 1 and Figure 3 As shown, two first slide rails 23 are symmetrically arranged on the U-shaped frame 2 and the long hole 26 is located between the two first slide rails 23. A slider 24 is provided on each first slide rail 23 and the two sliders 24 are distributed opposite each other. High-strength connecting rods 25 connected to the feeding box 3 are symmetrically arranged on the sliders 24.

[0041] Further refinement of the embodiment of the present invention, such as Figure 2 As shown, a material level sensor 32 is provided at the top of the inner portion of the feeding box 3, and is specifically an ultrasonic material level sensor.

[0042] Further refinement of the embodiment of the present invention, such as Figure 2 As shown, a stirring assembly 33 is provided in the feeding box 3 below the feeding port 31. The stirring assembly 33 belongs to the existing technology and is not improved. It includes a driving motor, a rotating shaft and a turning rod. The above components are not numbered in the figure.

[0043] It should be noted that the powder delivery pump, the star-shaped feeder 4, the multi-stage electric push rod 21, the material level sensor 32 and the stirring assembly 33 are all electrically connected to the controller, which is not shown in the figure.

[0044] The workflow of this utility model:

[0045] In the initial state, the controller controls the multi-stage electric push rod 21 to move and drive the feeding box 3 to stop at one end of the long hole 26. In the movement process, the sliding block 24 can move along the first sliding rail 23 to provide guidance, and the multi-stage telescopic rod 22 synchronously extends and retracts with the multi-stage electric push rod 21. Then the controller controls the powder conveying pump to work to extract the material from the sintering machine head ash storage and inject it into the feeding box 3 from the feeding port 31. At this time, the material level sensor 32 can detect the accumulation height of the sintering machine head ash in real time, and the star-shaped feeder 4 is in the stop state.

[0046] When the injection height reaches the pre-set upper limit, the material level sensor 32 feeds back a signal to the controller, and the controller controls the powder conveying pump to stop working. At the same time, the motor in the star-shaped feeder 4 starts to work at a pre-set speed to quantitatively and uniformly feed the double-shaft stirring device 1. At the same time, the multi-stage electric push rod 21 drives the feeding box 3 to move uniformly from left to right, so that the multi-point reciprocating injection process of the sintering machine head ash to different areas of the double-shaft stirring device 1 can be realized.

[0047] In the process of reciprocating uniform injection, the feeding box 3 is not hindered in movement because it is connected with the powder conveying pump through a hose. If the sintering machine head ash accumulates and the unloading is not smooth during the feeding process, the controller controls the stirring assembly 33 to move to effectively stir the sintering machine head ash to ensure smooth unloading. In combination with the operation of the star-shaped feeder 4, the multi-point quantitative and uniform feeding process into the double-shaft stirring device 1 can be realized, which greatly reduces the labor intensity of the original manual operation of the loader and makes the feeding amount more accurate.

[0048] Compared with the prior art, the device can realize the automatic reciprocating multi-point quantitative and uniform feeding process into the double-shaft stirring device 1, thereby avoiding the phenomenon of excessively high or low local sintering machine head ash concentration, prolonging the service life of the stirring device, reducing the labor intensity, and making the feeding amount control more accurate and the sintering machine head ash feeding effect better.

[0049] In some embodiments, as shown in Figure 4 The star-shaped feeder 4 is symmetrically provided with a connecting rod 41, and the double-shaft stirring device 1 is symmetrically provided with a second sliding rail 42 in sliding cooperation with the connecting rod 41. This embodiment can provide support at the bottom of the feeding box 3 to prolong the service life of the first sliding rail 23.

[0050] In other embodiments, as shown in Figure 4As shown, there is a PVC transparent door curtain 5 between the double-shaft stirring device 1 and the U-shaped frame 2, and the PVC transparent door curtain 5 is symmetrically distributed about the U-shaped frame 2; the embodiment can effectively reduce the amount of dust generated in the sintering machine head ash stirring process to overflow into the surrounding environment, and further effectively reduce the phenomenon of dust overflow by cooperating with the spraying and humidifying function of the double-shaft stirring device 1 itself.

[0051] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
