TECHNICAL FIELD
[0001] The utility model relates to foundry technology field especially relates to a telescopic sand receiving device. BACKGROUND
[0002] Sand casting is a process method with a long history and the widest application range, which uses clay bonded sand as molding material to produce castings. In the casting process, after the casting is poured, the sand mold is cooled for a certain period of time, and then the sand box needs to be turned over and the sand is dropped. The hot sand in the sand box and the casting are poured onto the screen of the sand drop device, the casting is left on the upper part of the screen, and the hot sand passes through the screen into the old sand regeneration device for processing to realize the reuse of old sand.
[0003] During sand receiving, the sand receiving groove is placed at the discharge port position of the old sand regeneration device, and the staff connects the sand receiving groove to the shelf adjacent to the discharge port. However, due to the long length of the sand receiving groove and the narrow working space, it is difficult and laborious for the staff to operate, and there is a safety hazard during the sand receiving process. In addition, when idle, it occupies a large working space, which is very inconvenient to use. SUMMARY
[0004] In view of the above problems that the length of the sand receiving groove is large, it is inconvenient to connect and laborious, and it occupies a large working space, and there is a safety hazard during the connecting operation, the utility model provides a telescopic sand receiving device.
[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:
[0006] A telescopic sand receiving device comprises a support frame, a sand receiving groove and a sand receiving hopper. The sand receiving groove is inclined and arranged on one side of the top of the support frame. The sand receiving hopper is adjacent to the support frame and located below the discharge port of the sand receiving groove. The sand receiving groove comprises a first sand receiving groove and a second sand receiving groove. The first sand receiving groove is arranged in the second sand receiving groove and moves along the second sand receiving groove. The top of the first sand receiving groove is provided with a limiting part. The first sand receiving groove is connected with the second sand receiving groove through the limiting part.
[0007] Further, the support frame is a frame structure, and the sand receiving groove is fixedly connected to the right side edge of the top of the support frame.
[0008] Further, the two side edges of the top of the second sand receiving groove are bent inward to form a U-shaped sliding groove. The top edge of the first sand receiving groove is arranged in the U-shaped sliding groove and moves along the U-shaped sliding groove.
[0009] Furthermore, the limiting part is fixed to the bottom of the first sand receiving groove, and the limiting part is plate-shaped or hook-shaped.
[0010] Furthermore, a collection pipe is fixed at the discharge port at the lower part of the second sand receiving trough. The collection pipe is hollow inside, and its side wall is fixedly connected to the side wall of the support frame.
[0011] Furthermore, the collection pipe is located above the sand receiving hopper.
[0012] The beneficial effects of this utility model are as follows: This utility model utilizes the relative movement between the first and second sand receiving troughs, allowing the sand receiving troughs to achieve telescopic posture changes. Furthermore, the use of a support frame as support for the sand receiving troughs prevents movement during sand receiving, effectively improving the stability of sand receiving. In this utility model, a collection pipe limits the flow of sand through the first and second sand receiving troughs, preventing sand from splashing out due to collision when sliding out at high speed from the outlet of the second sand receiving trough, ensuring that the sand accurately enters the sand receiving hopper.

[0013] Figure 1 The diagram shown is a schematic diagram of the structural principle of one embodiment of this utility model.
[0014] Figure 2 As shown Figure 1 The left view.
[0015] Figure 3 As shown Figure 1 A side view. Detailed Implementation
[0016] This utility model discloses a retractable sand receiving device. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.
[0017] like Figure 1 As shown, the sand receiving device includes a support frame 1, a sand receiving trough, and a sand receiving hopper 5. The support frame 1 is a frame structure, and the sand receiving trough is located on the right side of the top of the support frame 1. The sand receiving trough includes a first sand receiving trough 2 and a second sand receiving trough 3, with the first sand receiving trough 2 disposed within the second sand receiving trough 3. The top edge of the second sand receiving trough 3 is bent inward to form a U-shaped groove, and the top edge of the first sand receiving trough 2 is disposed within the U-shaped groove and moves along the U-shaped groove.
[0018] Combination Figure 2 and Figure 3The bottom of the first sand receiving groove 2 is fixed with a limiting part 6, and the first sand receiving groove 2 is clamped with the second sand receiving groove 3 through the limiting part 6. The limiting part 6 is in a plate shape or a hook shape. In the embodiment, the limiting part 6 is in a plate shape. In the static state, the top of the first sand receiving groove 2 is clamped on the top of the second sand receiving groove 3 through the limiting part 6 in a plate shape. The discharge port of the lower part of the second sand receiving groove 3 is fixed with a collecting pipe 4, the inside of the collecting pipe 4 is hollow, and the side wall of the collecting pipe 4 is fixedly connected with the right side wall of the support frame 1. The discharge port of the lower part of the second sand receiving groove 3 is fixed with a collecting pipe 4, the inside of the collecting pipe 4 is hollow, and the side wall of the collecting pipe 4 is fixedly connected with the right side wall of the support frame 1. The sand receiving hopper 5 is located below the collecting pipe 4.
[0019] The bottom of the first sand receiving groove 2 is fixed with a limiting part 6, and the first sand receiving groove 2 is clamped with the second sand receiving groove 3 through the limiting part 6. In the static state, the top of the first sand receiving groove 2 is clamped on the top of the second sand receiving groove 3 through the limiting part 6 in a plate shape. The discharge port of the lower part of the second sand receiving groove 3 is fixed with a collecting pipe 4, the inside of the collecting pipe 4 is hollow, and the side wall of the collecting pipe 4 is fixedly connected with the right side wall of the support frame 1.
