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.

[0037] Example

[0038] See also Figures 1 to 5 A crucible feeder comprises a feeding barrel 1, a blocking cover 4, a feeding opening and closing control mechanism and a hanging component. A feeding port 2 and a feeding port 3 are respectively arranged at the top and the bottom of the feeding barrel 1. Two blocking covers 4 are symmetrically hinged at the feeding port 3. The feeding opening and closing control mechanism is slidably arranged on the outer wall of the feeding barrel 1 along the height direction of the feeding barrel 1, and is used for slidingly controlling the opening or closing of the two blocking covers 4. The hanging component is arranged on the outer wall of the feeding barrel 1, and is used for holding the feeding barrel 1.

[0039] In this embodiment, the feeding opening and closing control mechanism includes two symmetrically arranged pulling components, and the pulling components include a pull rod 101, a rotating rod 102, a connecting plate 103 and a connecting rod 104. The pull rod 101 is symmetrically slidably set on the outer wall of the feeding barrel 1 along the height direction of the feeding barrel 1, and the top of the pull rod 101 is rotatably connected to the rotating rod 102, and the connecting plate 103 is fixedly connected to the bottom of the pull rod 101. Two connecting rods 104 are symmetrically rotatably connected to the connecting plate 103, and the two connecting rods 104 are respectively rotatably connected to one side of the two cover covers 4, wherein a hook handle 105 is fixedly connected between the two rotating rods 102 of the two pulling components. In order to facilitate the crane hook 5 to accurately hook the hook handle 105 and to be more stable and not easy to shake after hooking the hook handle 105, preferably, a hook 106 is fixedly connected to the hook handle 105.

[0040] In this embodiment, the hanging assembly includes a slide cylinder 201, a sliding rod 202 and a hook ring 203. The slide cylinder 201 is set in two, and the two slide cylinders 201 are symmetrically fixedly connected to the two sides of the outer wall of the feeding barrel 1. The inside of the two slide cylinders 201 is slidably installed with a sliding rod 202, and the top of the two sliding rods 202 is fixedly connected with a hook ring 203.

[0041] In this embodiment, a limit opening 204 is provided on the slide 201, a limit block 205 is fixedly connected to the slide rod 202, and the limit block 205 is slidably arranged in the limit opening 204, the highest sliding position of the limit block 205 in the limit opening 204 is the highest sliding range of the slide rod 202 in the slide 201, and the sliding of the slide rod 202 in the slide 201 can make the hook ring 203 rise and fall within a certain range, leaving a certain space for the operator to operate the hook handle 105.

[0042] In this embodiment, a plurality of sliding limit sleeves 107 are fixedly connected to the outer wall of the feeding barrel 1. The plurality of sliding limit sleeves 107 are divided into two groups. The two pull rods 101 are respectively slidably arranged in the two groups of sliding limit sleeves 107, thereby facilitating the stable lifting and sliding of the pull rods 101.

[0043] In summary, when the crucible feeder is used, after various raw materials for producing rare earth hydrogen storage alloys, rare earth permanent magnet alloys or other alloys are weighed according to the batching requirements, such as Figure 1 to Figure 2 As shown, in the state where the two blocking covers 4 close the feeding port 3 (generally, the feeding tube 1 is placed on the ground, and the two blocking covers 4 are closed. In another case, the hook handle 105 is hung upward, and the two blocking covers 4 are also closed under tension), after the batching in the batching section is completed, the batching is loaded into the feeding tube 1 according to the process operation flow requirements, and then the hook 106 can be hung by the crane hook 5. The hook 106 and the hook handle 105 make the two pulling components pull upward, so that the two blocking covers 4 are pulled to keep the feeding port 3 closed. After the crane hook 5 hangs the entire crucible feeder above the crucible of the smelting furnace, as shown in FIG. Figure 3 to Figure 4 As shown, the hook ring 203 is then hung by the overhead crane hook 6. After the crane hook 5 releases the hook 106, due to the loss of upward pulling force, the two blocking covers 4 are flipped downward under the combined action of their own gravity and the downward gravity of the ingredients in the feeding barrel 1, the feeding port 3 is open, and the ingredients in the feeding barrel 1 can be automatically poured downward into the crucible of the smelting furnace. After the feeding is completed, the crucible feeder can be lifted out.
