AI Technical Summary
When the existing pushing device has a long telescopic stroke, the retracted state length is too long, which causes the barrel flip device to be unusable in workshops with smaller spaces, and cannot have sufficient extension length and short retracted length at the same time.
A pushing device is designed, including a fixing part, a first pushing part, a second pushing part, a driving mechanism and a linkage mechanism. Through the linkage mechanism, the first pushing part and the second pushing part are synchronized out or retracted under the drive of the drive mechanism, so as to realize three-stage expansion and contraction, and nest and stack between the fixing part, the first pushing part and the second pushing part, thereby reducing the overall thickness and volume.
The pushing device has a short length when retracting while having sufficient extension stroke, which improves the structural compactness of the barrel flip device and is suitable for workshops with smaller spaces.

Abstract
Description
Technical Field
[0001] This application relates to the technical field of single crystal pulling, and specifically relates to a pushing device and a barrel tilting device. Background Art
[0002] Before feeding, the barrel needs to be rotated to a specific inclination angle to cooperate with the hopper for feeding, and returns to the vertical state after feeding.
[0003] Existing barrel tilting devices generally include a frame, a fixed frame rotatably installed on the frame, and a pushing device for pushing the fixed frame to rotate relative to the frame. The barrel can be assembled on the fixed frame, and then the pushing device is used to push the fixed frame to rotate relative to the frame from one side of the fixed frame, thereby driving the barrel to rotate to adjust the inclination angle of the barrel.
[0004] Existing pushing devices usually select cylinders. However, since the cylinder is a two-stage telescopic device, when the barrel requires a large inclination angle or the barrel is relatively high, a cylinder with a longer telescopic stroke is needed. However, when the cylinder with a longer telescopic stroke is in the retracted state, its length is too long, which will reduce the structural compactness of the barrel tilting device and cannot be used in a workshop with a small space. Therefore, there is an urgent need for a new pushing device. Utility Model Content
[0005] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application provides a pushing device to solve the problem that the existing pushing device cannot have both a sufficient extended length and a short length in the retracted state in the prior art.
[0006] The purpose of this application can be achieved through the following technical solutions:

The second linkage member bypasses the second driven wheel, and both ends of the second linkage member are fixedly connected to the second end of the fixed part and the second end of the second pushing part respectively.
[0025] By arranging the first driven wheel and the first linkage member, arranging the first driven wheel at the first end of the first pushing part, bypassing the first driven wheel with the first linkage member, and fixedly connecting both ends of the first linkage member to the first end of the fixed part and the first end of the second pushing part respectively, the second pushing part can follow the first pushing part to extend synchronously, and the second pushing part has a larger extension stroke;
[0026] And by arranging the second driven wheel and the second linkage member, arranging the second driven wheel at the second end of the first pushing part, bypassing the second driven wheel with the second linkage member, and fixedly connecting both ends of the second linkage member to the second end of the fixed part and the second end of the second pushing part respectively, the second pushing part can follow the first pushing part to retract synchronously, and the second pushing part has a larger contraction stroke.
[0027] Optionally: The first linkage member and / or the second linkage member includes one of a belt, a toothed belt, a chain, a steel belt or a pulley rope.

The driving assembly is installed on the vertical plate 101, and the driving assembly is configured to drive the driven member 131 to linearly move along the first direction, so that the first pushing portion 11 extends or retracts relative to the fixing portion 10.

[0050] Please refer to Figure 2 and Figure 3As shown, in some embodiments, the linkage mechanism 14 includes a first linkage component 141 and a second linkage component 142. The first linkage component 141 includes a first driven wheel 1411 and a first linkage member 1412. The first driven wheel 1411 is disposed at the second end 112 of the first pushing portion. The second end 112 of the first pushing portion is provided with a first receiving groove 21 for receiving the first driven wheel 1411.

[0053] When the pushing device 100 needs to retract, the motor rotates in reverse to drive the rack to move in the reverse direction along the first direction through the gear, so that the first pushing part 11 gradually retracts relative to the fixed part 10. During this process, the first pushing part 11 is in transmission cooperation with the second linkage member 1422 through the second driven wheel 1421, so that the part of the second linkage member 1422 located above the first pushing part 11 gradually moves to below the first pushing part 11, and then the second linkage member 1422 pulls the second pushing part 12 to gradually retract relative to the first pushing part 11 synchronously. And during this process, the second pushing part 12 pulls the first linkage member 1412 to move synchronously, so that the part of the first linkage member 1412 located below the first pushing part 11 gradually moves to above the first pushing part 11.
