[0028] See also Figure 1-3As shown, the utility model provides a trolley for a feeding barrel, and the trolley for the feeding barrel 30 includes a trolley body 1 and a fixed bracket 2 arranged on the trolley body 1. The fixed bracket 2 is provided with a base 3 for supporting the bottom of the feeding barrel 30 and a driving mechanism for driving the base 3 to rotate, and the driving mechanism is connected to the base 3 in a transmission manner to drive the base 3 to rotate relative to the fixed bracket 2. Among them, the driving mechanism includes a worm wheel 4, a worm 5 meshing with the worm wheel 4, and a driving member 6 for driving the worm 5 to rotate, and the worm wheel 4 is fixedly connected to the base 3. The worm wheel 4 and the worm 5 are used as a transmission mechanism, which has a good load-bearing effect and is suitable for the load-bearing of the heavier feeding barrel 30 and materials in the field of single crystal pulling. In addition, its self-locking function can improve the stability of the rotation of the feeding barrel 30.
[0029] In actual use, the feeding barrel 30 is installed on the base 3. When the feeding barrel 30 needs to be rotated, the worm 5 is driven by the driving member 6, so that the worm 5 drives the worm wheel 4 to rotate, and then the worm wheel 4 drives the base 3 and the feeding barrel 30 located on the base 3 to rotate synchronously, so that the feeding barrel 30 is rotated to a specific direction forward posture to cooperate with the hopper (not shown) to add materials. Compared with the manual rotation of the feeding barrel 30 in the prior art, the present application uses the worm wheel 4 and worm 5 mechanism to drive the base 3 to rotate, and then realizes the rotation of the feeding barrel 30 on the base, which is labor-saving and efficient, and greatly reduces the labor intensity of workers. In one example, the driving member 6 is a manually driven driving member 6, and the driving member 6 includes a first rotating shaft 61 rotatably arranged on the fixed bracket 2, a handwheel 62 detachably mounted on the end of the first rotating shaft 61, a first sprocket 63 fixedly arranged on the first rotating shaft 61, a second sprocket 64 fixedly arranged on the shaft of the worm 5, and a chain 65 wound around the first sprocket 63 and the second sprocket 64.
[0030] By rotating the hand wheel 62, the hand wheel 62 drives the first rotating shaft 61 to rotate, the first rotating shaft 61 drives the first sprocket 63 to rotate, the first sprocket 63 drives the second sprocket 64 to rotate through the chain 65, the second sprocket 64 drives the worm 5 to rotate, the worm 5 drives the worm wheel 4 to rotate, and the worm wheel 4 drives the base 3 to rotate, thereby causing the base 3 to drive the feeding barrel 30 to rotate.
[0031] Furthermore, in order to keep the staff's body posture in a comfortable state during the rotation of the feeding barrel 30, the first rotating shaft 61 is arranged above the worm 5. The specific height of the first rotating shaft 61 from the ground can be set according to the height of the staff, and no specific limitation is made here, so as to avoid the staff from bending over significantly during the process of turning the handle 13, which will cause work fatigue.
[0032] In another example, the driving member 6 may also be a motor (not shown). In this case, the driving shaft of the motor is connected to the worm 5. Compared with the manually driven driving member 6 in the previous example, using a motor as the driving member 6 saves manpower and is more convenient and quick.
[0033] In one example, a mounting base 7 is fixedly provided on the fixed bracket 2, and the worm wheel 4 is rotatably mounted on the mounting base 7, and the worm wheel 4 is fixedly mounted on the bottom of the base 3. Specifically, the mounting base 7 includes a disc-shaped chassis 71 and a disc-shaped limiting plate 72 protruding from the middle of the chassis 71. The worm wheel 4 is generally annular, and the worm wheel 4 is sleeved on the limiting plate 72, and the worm wheel 4 and the limiting plate 72 are rotatably connected through a bearing. There is an avoidance gap between the worm wheel 4 and the chassis 71 to avoid friction between the worm wheel 4 and the chassis 71 when the worm wheel 4 rotates relative to the chassis 71. The base 3 is arranged above the worm wheel 4, and the bottom of the base 3 is fixedly connected to the worm wheel 4 by bolts, so that the base 3 can rotate synchronously with the worm wheel 4 relative to the mounting base 7.
[0034] In one example, the base 3 includes a disc body 31 and a fence 32 protruding from the edges of the disc body 31. The fence 32 can limit the feeding barrel 30 from the outside to prevent the feeding barrel 30 from deviating from the base 3. A limiting protrusion 33 is provided in the middle of the base 3. The limiting protrusion 33 can be inserted into a limiting groove located at the bottom of the feeding barrel 30 and adapted to the limiting protrusion 33, so that the limiting protrusion 33 limits the feeding barrel 30 to prevent the feeding barrel 30 and the base 3 from moving relative to each other.
[0035] Furthermore, the limiting protrusion 33 is in a truncated cone shape, and the side surface of the limiting protrusion 33 is a conical surface, and the diameter of the conical surface gradually increases from top to bottom, which facilitates the assembly between the limiting protrusion 33 and the limiting groove at the bottom of the feeding barrel 30.
[0036] In one example, the trolley body 1 includes a frame 11, a roller 12 installed at the bottom of the frame 11, and a handle 13 installed at the top of the frame 11. The frame 11 is open at the top, and there is a cavity inside the frame 11. The handle 13 is arranged along the width direction of the frame 11. In actual use, the staff can easily push the trolley body 1 to move freely by holding the handle 13.
[0037] In one example, the fixed bracket 2 is rotatably connected to the trolley body 1 through the second rotating shaft 8, so that the fixed bracket 2 can drive the feeding barrel 30 to swing relative to the vehicle frame 11 to adjust the inclination angle of the feeding barrel 30. Specifically, the second rotating shaft 8 is arranged along the width direction of the vehicle frame 11, and one end of the second rotating shaft 8 is rotatably connected to the top of the vehicle frame 11 through a mounting seat. The fixed bracket 2 includes a swing mounting frame 21 that partially extends into the vehicle frame 11, a tray 22 fixedly mounted at the bottom of the swing mounting frame 21, and a first mounting frame 23 fixedly mounted on one side of the tray 22. The swing mounting frame 21 is fixedly connected to the other end of the second rotating shaft 8, so that the entire fixed bracket 2 can be rotated to a vertical position and an inclined position of a predetermined angle with the second rotating shaft 8 as a fulcrum, and then the inclination angle of the feeding barrel 30 can be adjusted by rotating the fixed bracket 2. In this example, the mounting base 7 is fixedly mounted on the tray 22, the worm 5 is rotatably mounted on the tray 22 through two mounting seats, and the first rotating shaft 61 is rotatably mounted on the first mounting frame 23 through a bearing.
[0038] In one example, in order to prevent the feeding barrel 30 from moving relative to the fixed bracket 2 during the tilting process, a plurality of restraints 9 are vertically spaced on the swing mounting frame 21, and the restraints 9 are used to restrain the feeding barrel 30 on the swing mounting frame 21. Preferably, the restraints 9 have a lock 91, and when the restraints 9 need to restrain the feeding barrel 30, the feeding barrel 30 can be restrained on the swing mounting frame 21 by simply fastening the lock 91; when the restraints of the feeding barrel 30 need to be released, the lock 91 only needs to be unlocked, which is convenient and quick.
[0039] See also Figure 4 As shown, in one example, a buffer 10 is also fixedly provided on the top of the vehicle frame 11. The buffer 10 is used to buffer the fixed bracket 2 when the fixed bracket 2 rotates to an inclined position of a predetermined angle with the second rotating shaft 8 as a fulcrum, so that the fixed bracket 2 can smoothly rotate to the inclined position of the predetermined angle.
[0040] In one example, a damping rod 20 is further provided on the side of the fixed bracket 2 facing the tilting direction, one end of the damping rod 20 is hinged to the trolley body 1, and the other end is hinged to the swing mounting frame 21, so that the damping rod 20 can make the fixed bracket 2 more stable during the process of resetting from the tilted state to the vertical state. Preferably, the damping rod 20 adopts a nitrogen spring.
[0041] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
