Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology, specifically referring to a positioning material feeding device for a conveyor crane. Background Technology

[0002] Sapphire polycrystalline material is made by high-purity alumina powder through high-temperature sintering. The entire sintering process can be divided into three main steps: feeding, high-temperature sintering (crystal growth), and unloading. During the sintering process, the position of the heating furnace remains fixed.

[0003] To improve production capacity and plant utilization, production workshops typically have multiple sintering furnaces arranged in parallel, each capable of independent sintering operations. However, feeding each sintering furnace separately leads to low feeding and management efficiency. Therefore, to optimize management and simplify the feeding process, a conveyor crane is usually used to feed materials uniformly from the top of the hopper.

[0004] Due to equipment adjustments, raw material backlogs, or other production factors, the time and location for feeding materials are often unpredictable. Therefore, feeding operations need to be highly flexible, capable of being performed at any location and time. This makes it impossible for the feeding system to use a pre-set programming mode, and it is difficult to achieve automated program control. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a positioning and feeding device for a conveyor crane, which at least partially solves the above problems.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a positioning and feeding device for a conveying crane, including a feeding hopper for conveying raw materials, and the lower end of the feeding hopper is provided with a discharge port;

[0007] A conical nozzle is flexibly connected to the lower end of the discharge port, and a plug is fixed to the upper end of the conical nozzle by a connecting rod. The plug is adapted to the inner hole of the discharge port.

[0008] Furthermore, a fixed flange is provided on the outer wall of the discharge port, and multiple sets of guide pillars are slidably arranged on the fixed flange. A sliding flange is provided at the lower end of the guide pillar, and a spring is arranged around the guide pillar. The spring is connected between the fixed flange and the sliding flange.

[0009] Furthermore, the upper end of the conical nozzle is disposed through the center of the sliding flange.

[0010] Furthermore, a corrugated pipe is connected between the conical nozzle and the discharge port, and the connecting rod passes through the corrugated pipe.

[0011] Furthermore, the upper end of the cone nozzle is provided with multiple sets of cross-arranged support rods, and the connecting rod is provided on the support rods.

[0012] Furthermore, the positioning and feeding device for a conveying trolley proposed in this utility model also includes a conveying trolley, a receiving hopper, and a lifting device. The feeding hopper is connected to the lower end of the conveying trolley through the lifting device, and the receiving hopper is arranged below the conveying trolley. When the cone nozzle comes into contact with the receiving hopper, it will be compressed and driven to seal and separate from the discharge port.

[0013] The beneficial effects of this utility model are as follows: after the cone nozzle is pressed, it is pushed upward, which can push the seal and the discharge port to separate, so that the material in the feeding hopper is poured downward into the receiving hopper. The entire equipment operates by the gravity of the material to trigger feeding. The operating structure is simple and efficient. It does not rely on electrical programming control and can realize feeding operation at any required location and time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-4 As shown in the embodiment of this utility model, a positioning and feeding device for a conveying trolley 1 includes a conveying trolley 1, a receiving hopper 2, a lifting device 3, a feeding hopper 4, and a conical nozzle 11. The feeding hopper 4 is connected to the lower end of the conveying trolley 1 via the lifting device 3. The lifting device 3 is driven by an electric hoist, which moves the feeding hopper 4 vertically. The receiving hopper 2 is arranged below the conveying trolley 1. The feeding hopper 4 is filled with the conveying raw material (i.e., high-purity alumina). When filling the material, the feeding hopper 4 is in a low position. When conveying the material, the feeding hopper 4 is driven to a high position by the lifting device 3. When the hopper 4 moves above the receiving hopper 2, the lifting device 3 drives the feeding hopper 4 to move down to a height that matches the receiving hopper 2. The lower end of the feeding hopper 4 is provided with a discharge port 5. When feeding, the raw material is transported to the receiving hopper 2 through the discharge port 5. The cone nozzle 11 is elastically connected to the lower end of the discharge port 5. The upper end of the cone nozzle 11 is fixed with a plug 14 through the connecting rod 13. The plug 14 matches the inner hole of the discharge port 5. When the cone nozzle 11 contacts the receiving hopper 2, the receiving hopper 2 applies a pushing force to the cone nozzle 11. The cone nozzle 11 will slide upward and retract, driving the plug 14 to separate from the discharge port 5, thereby opening the discharge port 5.

[0023] In some embodiments, a fixed flange 6 is provided on the outer wall of the discharge port 5, and multiple sets of guide pillars 7 are slidably provided on the fixed flange 6. A sliding flange 9 is provided at the lower end of the guide pillar 7, and a spring 8 is surrounded on the guide pillar 7. The spring 8 is connected between the fixed flange 6 and the sliding flange 9. The spring 8 always pushes the sliding flange 9 downward. When the feeding hopper 4 is in a high position, the cone nozzle 11 under the discharge port 5 is not subjected to any external force. The spring 8 pushes the sliding flange 9 to move downward, thereby driving the cone nozzle 11 to move downward. The seal 14 is sealed with the discharge port 5. At this time, the material in the feeding hopper 4 cannot flow downward, so that the feeding hopper 4 can be transferred.

[0024] In some embodiments, the upper end of the cone nozzle 11 is disposed through the center of the sliding flange 9, and a bellows 10 is connected between the cone nozzle 11 and the discharge port 5. The connecting rod 13 is disposed through the bellows 10. When the cone nozzle 11 is pressed and slides upward, the bellows 10 will also contract. When the cone nozzle 11 slides downward under the heavy pressure of the material above, the bellows 10 will also extend again. The bellows 10 can follow the position of the cone nozzle 11 and can ensure a sealed connection between the discharge port 5 and the cone nozzle 11, so that there will be no leakage.

[0025] In some embodiments, the upper end of the conical nozzle 11 is provided with multiple sets of cross-arranged support rods 12, and the connecting rod 13 is provided on the support rod 12. There is a certain gap between the support rods 12, and the diameter of the connecting rod 13 is also smaller than the diameter of the inner hole of the discharge port 5. When the plug 14 is separated from the discharge port 5, the raw material in the feed hopper 4 will fall down through the gap between the connecting rod 13 and the inner hole of the discharge port 5, and then fall through the gap between the support rods 12, and finally fall from the conical nozzle 11 into the receiving hopper 2.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
