[0001] This utility model relates to the technical field of silicon carbide crystal growth equipment, and in particular to a hot field feeding device. Background Technology

[0002] Silicon carbide crystal growth furnaces are high-temperature furnaces, with internal temperatures reaching approximately 2400℃. They require precise installation of the thermal field, which must remain parallel to the ground throughout the installation process. Otherwise, uneven crystal distribution inside the crucible will affect the crystal growth quality. Existing patent CN216336134U, "A Suspension Device for a Thermal Field in Crystal Manufacturing," uses a cantilever crane and cage-type tooling fixtures to hoist thermal field components such as the crucible and finally install them into the furnace body. However, this device has high requirements for operating space. It cannot be used in small spaces with rows of equipment due to narrow aisles and low rack entrance heights; furthermore, it cannot be operated by a single person, and in larger spaces, it requires multiple people, impacting production efficiency. Utility Model Content

[0004] Technical solution: To solve the above problems, this utility model adopts a hot zone feeding device, including a forklift, a movable beam, and a load-bearing clamp. The movable beam includes a mounting plate, a main beam, a guard plate, and a fork plate. The mounting plate is connected to the forklift, the main beam is fixedly mounted on the mounting plate, the fork plate is mounted below the main beam through a connecting rod, and the guard plate is slidably mounted on the mounting plate.

[0005] The connecting rod includes a telescopic rod body and spheres located at both ends of the rod body. Grooves for mounting the spheres are provided on the main beam and the fork plate. The bearing fixture includes a bearing base and a handle mounted on the bearing base. When loading, the fork plate lifts the bearing base, and the forklift is used to adjust the position and height of the fork plate.

[0006] Furthermore, the mounting plate is also equipped with a left-right turn screw, a handwheel, and a linear guide rail. The handwheel is connected to the left-right turn screw for rotating the left-right turn screw. The linear guide rail is arranged parallel to the left-right turn screw, and two sliders are provided on the linear guide rail. The sliders are connected to the mover of the left-right turn screw, and the guard plates are installed on the sliders. By rotating the handwheel, the two guard plates move in opposite directions.

[0007] Furthermore, the connecting rod includes a sleeve and an internal threaded rod. One end of the sleeve is provided with a ball, and the other end of the sleeve is provided with a mounting hole for installing the internal threaded rod, and the mounting hole is provided with an internal thread. One end of the internal threaded rod is provided with a ball, and the other end of the internal threaded rod is provided with an external thread. The extension and retraction of the connecting rod can be achieved by adjusting the length of the internal threaded rod screwed into the mounting hole.

[0008] Furthermore, the fork plate is provided with a positioning pin, and the bearing base is provided with a positioning pin hole whose position matches the positioning pin.

[0019] like Figure 1 As shown, a hot zone loading device in this embodiment includes a forklift 1, a movable beam 2, and a load-bearing clamp 3. The forklift is a mature existing technology, and its structure will not be described in detail here. The forklift 1 is used to adjust the position and height of the movable beam 2. Figure 2 As shown, the movable beam 2 includes a mounting plate 21, main beams 22, guard plates 27, and fork plates 29. The mounting plate 21 is connected to the forklift 1. The two main beams 22 are fixedly installed on the mounting plate 21, and the axes of the main beams 22 are perpendicular to the plane of the mounting plate 21. The fork plates 29 are installed below the main beams 22 via four connecting rods 28. The main beams 22 are also equipped with retaining beams 211 to limit and protect the thermal field, preventing it from tipping forward.

[0020] like Figure 3 and Figure 4 As shown, the connecting rod 28 includes a sleeve rod 281 and an internal thread rod 282. One end of the sleeve rod has a ball, and the other end has a mounting hole for the internal thread rod, with an internal thread inside. One end of the internal thread rod has a ball, and the other end has an external thread. The extension and retraction of the connecting rod 28 are achieved by adjusting the length of the internal thread rod screwed into the mounting hole, thereby adjusting the distance between the fork plate and the main beam. This ensures that the fork plate 29 is in a horizontal position and does not damage the uniformity of the powder inside the hot zone crucible. The main beam 22 and the fork plate 29 have grooves for the ball to be installed. The connection is achieved through spherical contact. When there is a deviation between the center of the movable beam and the center of the hot zone, the ball can self-adaptively contact to achieve correct installation.

[0021] The guard plate 27 is slidably mounted on the mounting plate 21. Specifically, the mounting plate 21 is equipped with a left-to-right turn screw 23, a handwheel 24, and a linear guide rail 25. The handwheel 24 is connected to the left-to-right turn screw 23 and is used to rotate the screw. The linear guide rail 25 is arranged parallel to the left-to-right turn screw 23 and has two sliders 26, which are connected to the movers of the left-to-right turn screw 23. The guard plate 27 is mounted on the sliders 26 and is arc-shaped to fit the outer surface of the hot zone. During feeding, the guard plates 27 are located on both sides of the hot zone to limit and protect it. By rotating the handwheel 24, the two guard plates 27 can be moved in opposite directions to adjust the distance between them to accommodate hot zones of different diameters.

[0022] like Figure 5As shown, the support fixture 3 includes a support base 31 and four foldable handles 33 mounted on the support base 31. Operators can use the handles 33 to lift and adjust the position of the heating element, allowing for single-person or multi-person loading. The support base 31 includes a top plate, a bottom plate, and connecting columns for connecting the top and bottom plates, with the top and bottom plates arranged parallel to each other. Several arc-shaped grooves of different diameters are formed on the upper surface of the top plate. Heating elements of different diameters can be placed in the corresponding grooves for initial positioning and fixation. A raised surface is provided on the lower surface of the top plate, and a concave surface with a shape matching the raised surface is provided on the upper surface of the fork plate 29. When the fork plate 29 lifts the support base 31, the raised surface and the concave surface fit together to lock and limit the support base 31, making it more stable during loading. To further secure the support base 31 and ensure the stability of the thermal field during loading, a positioning pin 210 is provided on the fork plate 29, and a positioning pin hole 32 is provided on the top plate to match the positioning pin 210. When the fork plate 29 lifts the support base 31, the positioning pin 210 is installed in the positioning pin hole 32 to fix the support base 31.

[0023] The working process of this utility model is as follows: First, the hot zone is placed in the corresponding size groove on the top plate of the support base 31. The forklift 1 is controlled to lower the fork plate 29 between the top plate and the bottom plate, and then extend the fork plate 29 so that it is directly below the hot zone. The height of the fork plate 29 is adjusted so that the convex surface of the top plate is in contact with the concave surface of the fork plate. The positioning pin 210 is installed in the positioning pin hole 32 to fix the support base 31. After fixing the support base 31, the guard plate 27 is adjusted so that it abuts against the outer wall of the hot zone. The hot zone is transported to the installation position by the forklift 1 driving the fork plate 29, and then the fork plate is removed.

[0024] This utility model utilizes a forklift lifting method for material loading, requiring minimal space and allowing for use in small, interconnected equipment spaces. The connecting rod enables flexible installation of the fork plates, allowing adjustment of their height and angle to accommodate different thermal zones and enhance device flexibility. The support base and guard plate can adapt to thermal zones of varying sizes, improving the device's applicability. Single-person loading is possible, significantly increasing loading efficiency. Furthermore, multiple limiting and fixing mechanisms, including grooves, positioning pins, and guard plates, ensure the stability, safety, and positional consistency of the loading process, thereby guaranteeing the subsequent crystal growth quality.
