Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0050] Embodiment 1

[0051] A kind of crucible dumping mechanism, comprising: crucible 4, support plate 3, chassis 1, vertical support rod 2 and hydraulic push-pull rod 5;

[0052] As Figure 1 Shown, chassis 1 is symmetrically provided with two, in the front end of two chassis 1 and between two chassis 1 is connected with cross frame;Chassis 1 is made of I-beam or square steel material;Whole chassis 1 is as the overall support base of crucible 4;In the front side of chassis 1, and located at the two ends of cross frame symmetrically set two vertical support rods 2;Vertical support rod 2 also uses square steel material.

[0053] Close to the upper end of crucible 4, and located at the two sides of crucible 4 symmetrically set two support plates 3;Support plate 3 is made of steel material, is welded on the side wall of crucible 4.Located at the front side of two support plates 3, each is provided with a support plate hinge seat 201, the upper end of two vertical support rods 2 is provided with a hinge round block;Hinge round block is arranged in support plate hinge seat 201, is transversely inserted into a hinge screw rod, the upper end of vertical support rod 2 is hinged to the front side of support plate 3, support plate 3 and the crucible 4 connected with support plate 3 can be rotated with support plate hinge seat 201 as fulcrum.The whole fulcrum is as the center point of rotation of crucible 4 to occur inclination;The fulcrum is combined with vertical support rod 2, also as the auxiliary support point of crucible 4 during rotation, and after inclination;

[0054] In the embodiment, set hydraulic push-pull rod 5 as the power to push crucible 4 to rotate and incline;One root of hydraulic push-pull rod 5 is set at the two sides of crucible 4;As Figure 1 Shown, hydraulic push-pull rod 5 is arranged between the lower bottom surface of support plate 3 and chassis 1;The lower bottom surface of support plate 3, and the position close to the rear side of support plate 3 is provided with push-pull rod hinge seat 501;Chassis 1 is also provided with push-pull rod hinge seat 501 above;The upper end of hydraulic push-pull rod 5 is hinged between push-pull rod hinge seat 501 and support plate 3;The lower end of hydraulic push-pull rod 5 is hinged between push-pull rod hinge seat 501 and chassis 1.

[0055] Hydraulic push-pull rod 5 is controlled to extend or retract by its hydraulic control assembly;When hydraulic push-pull rod 5 extends, support plate 3 and crucible 4 rotate slowly with support plate hinge seat 201 as the rotating hinge point, and the material in crucible 4 begins to pour out when it inclines to a certain extent.

[0056] Because the upper end opening of crucible 4 is circular, there is no flow guide structure when the material is poured;When the flow of liquid material is large, the pouring material flow range is too large, and it is not easy to pour into the container, and it will be spilled;

[0057] As a preferred embodiment, as Figure 2As shown, a flow guide 301 is provided on the edge of the upper surface of the crucible 4; the flow guide 301 is configured as a part of the structure extending from the upper end of the crucible 4; a concave flow guide groove is opened in the middle of the flow guide 301, and the flow guide groove is connected to the space inside the crucible 4 that contains the material; when the material is poured, the material will flow out along the flow guide groove in the flow guide 301, keeping the material in a fixed flow line when poured, making it easy to pour into the container and avoiding spillage.

[0058] If the material is initially poured out, the flow rate may suddenly be too high, and the depth of the guide channel may be limited, causing the material to overflow from the guide channel; as a preferred implementation, such as Figure 1 As shown, a cover 7 is detachably installed on the guide port 301 above the guide port, and the detachable structure of the two is configured as follows:

[0059] A mating connecting plate 702 is provided on both sides of the upper surface of the guide port 301; similarly, a mating connecting plate 702 is also provided on both sides of the lower surface of the guide port cover 7; when the guide port cover 7 is placed above the guide port 301, the mating connecting plates 702 of the two will mate one by one; by passing bolts through the mating connecting plates 702 and tightening the nuts, the guide port 301 and the guide port cover 7 can be mated and connected.

[0060] like Figure 4 As shown, a guide channel is also formed on the bottom surface of the guide port cover 7. This guide channel is directly opposite the guide channel inside the guide port 301, and the two have the same width. With the guide port cover 7, no overflow will occur regardless of the flow rate of the material when it is poured out. Furthermore, after the guide port cover 7 is connected to the guide channel inside the guide port 301, the overall volume of the guide channel is increased, which increases the flow rate of the guided material.

[0061] As a preferred embodiment, such as Figure 4 As shown, a valve plate slot 703 is provided on the upper surface of the upper cover 7 near the front side of the guide port; the valve plate slot 703 communicates with the guide groove inside the upper cover 7; a valve plate 701 is movably disposed in the valve plate slot 703.

[0062] Pushing valve plate 701 down cuts off the flow guide port 301 and the flow guide groove inside the cover 7 above the flow guide port; conversely, pulling valve plate 701 up opens the flow guide groove. By setting valve plate 701, the material pouring can be controlled. This is suitable for situations where materials are divided into different containers. When one container is full, valve plate 701 is temporarily used to close the flow guide port. After the next container is placed, valve plate 701 is opened to pour the material. This avoids material spilling onto the ground and being wasted when changing containers.

[0063] As a preferred embodiment, since the material temperature is high, the temperature of the valve plate 701 after contacting the material is also high, and it cannot be directly touched by hand; therefore, as shown in Figure 4 , a hook hole 7011 is arranged above the valve plate 701; an iron hook tool is used to hook the valve plate 701, and the valve plate 701 is pulled up or pushed down.

[0064] As shown in Figure 1 , a plurality of bolt plates 101 are arranged on the side of the base frame 1; bolts are screwed into the bolt plates 101, and the bolts are embedded into the ground; the base frame 1 is fixed to the ground; and the entire device cannot be easily displaced and is more stable.

[0065] Example 2

[0066] Based on the basis of Example 1, in Example 1, when the material in the crucible 4 is poured out, the temperature of the material itself is very high, and hot air is generated around; these hot air will hinder the observation of the pouring condition and the filling condition of the container.

[0067] As shown in Figure 2 , in this embodiment, a plurality of blow nozzles 601 are arranged on the horizontal frame on the front side of the base frame 1; when the material is poured out, the air in the blow nozzles 601 blows on the material poured out;

[0068] A wind pipe 6 is arranged on the side of the base frame 1; the first end of the wind pipe 6 is in communication with the plurality of blow nozzles 601; and the second end of the wind pipe 6 is connected to a blower. The blower generates air, which reaches each blow nozzle 601 through the wind pipe 6 and is blown out.

[0069] By blowing the material through the blow nozzles 601, not only can the material just poured out be cooled and radiated to a certain extent, but also the generated hot air can be blown away, without affecting the observation of the pouring condition of the material and the filling condition of the container.

[0070] Example 3

[0071] Based on the basis of Example 1, in Example 1, the angle of the crucible 4 rotating and tilting is controlled by a person; and the material can be poured out only when the crucible 4 is tilted to a certain angle; and if the angle of the crucible 4 is too small, the pouring rate of the material may be slow; and if the angle of the crucible 4 is too large, the pouring rate of the material is too fast; in order to ensure the safety of operation, the material needs to be poured at a uniform speed.

[0072] As shown in Figure 3As shown, the embodiment is provided with an angle monitoring sensor 8 below one of the supporting plates 3; the angle monitoring sensor 8 can adopt a gyroscope angle sensor, or other types, can follow the rotation of the object, and monitor the rotation angle of the sensor; the angle monitoring sensor 8 is communicatively connected to the PLC; the hydraulic control assembly of the hydraulic push-pull rod 5 is communicatively connected to the PLC. The corresponding inclination angle value can be input in advance through the input end of the PLC according to the material quantity and flow rate; after the crucible 4 is driven to rotate and incline to the set angle value by the hydraulic push-pull rod 5, the PLC will issue an instruction to the hydraulic control assembly to make the hydraulic push-pull rod 5 stop working; in this way, the accurate control of the dumping angle of the crucible 4 can be realized.

[0073] The hydraulic push-pull rod 5 and the hydraulic control assembly belong to existing products, and the structure and principle thereof will not be described in detail here.

[0074] In the description of the present specification, the description of the terms "one embodiment", "example", "specific example" and the like means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are contained in at least one embodiment or example of the present application.
