Description

Technical Field

[0001] This utility model relates to the field of precision casting technology, and in particular to a vibrating screen. Background Technology

[0002] A vibrating screen works by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two forces results in a complex rotary vibration of the screen surface.

[0003] When used in precision casting, vibrating screens are placed below rain-type sand washing machines for sand equalization. Currently, the vibrating screens are bolted to the sand washing machine, which generates significant noise and is inconvenient for disassembly and cleaning. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a vibrating screen to solve the problems of excessive noise and inconvenient cleaning of existing vibrating screens.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A vibrating screen for sand equalization in a sand washing machine, comprising a screen body, a connecting assembly, and a lifting assembly;

[0007] The screen body is located below the sand washing machine, and the connecting component is used to connect the screen body and the sand washing machine; the lifting component is located at the end of the screen body away from the connecting component and is used to raise and lower the screen body.

[0008] The connecting component is a belt structure, and the lifting component includes a wire rope and a ratchet.

[0009] Furthermore, the connecting assembly includes a belt and pulleys.

[0010] Furthermore, the pulley includes a first pulley and a second pulley, the first pulley being disposed on the sand washing machine, and the second pulley being disposed on one side of the screen body.

[0011] Furthermore, the first pulley and the second pulley are connected by a belt.

[0012] Furthermore, the connecting components are in two sets, with the two sets of connecting components respectively disposed on both sides of the screen body.

[0013] Furthermore, the ratchet is located at the lower part of the screen body, one end of the wire rope is connected to the ratchet, and the other end of the wire rope is connected to the screen body.

[0014] Furthermore, the lifting assembly also includes a pulley, which is disposed on the screen body, and the wire rope is wound around the pulley.

[0015] Furthermore, the sieve body is inclined.

[0016] Furthermore, the screen body is provided with screen holes of different diameters for filtering molding sand of different diameters.

[0017] Furthermore, the sieve body is provided with a support partition, which is vertically arranged.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] (1) Compared with the existing technology, the vibrating screen is bolted to the sand washing machine, which generates a lot of noise. This utility model adopts a belt structure for flexible connection between the sand washing machine and the vibrating screen, which can reduce noise and effectively absorb and buffer the vibration transmission between the sand washing machine and the vibrating screen, avoid the vibration superposition caused by rigid connection, reduce component wear, and extend the service life of the equipment.

[0020] (2) The present invention provides a lifting component at the end of the vibrating screen away from the connecting component. The lifting component includes a wire rope, a ratchet and a pulley. The wire rope is placed between the pulley and the ratchet, and the ratchet is placed below the vibrating screen. The rotation of the ratchet causes the wire rope to drive the pulley and the other end of the vibrating screen to rise and fall. On the one hand, this makes it easy to remove the vibrating screen. On the other hand, through the repeated rising and falling of the vibrating screen, the molding sand is fully vibrated and screened.

[0021] (3) The screen body has screen holes of different diameters to filter molding sand of different diameters, thereby improving the working efficiency of the vibrating screen; and the two ends of the screen body are at different heights during operation, making it easy to pour out the molding sand inside the vibrating screen. The setting of the support baffle of the screen body can prevent the screen body from deforming.

[0022] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] A specific embodiment of this utility model is as follows: Figure 1 As shown, a vibrating screen for sand equalization in a sand washing machine is disclosed, comprising a screen body 1, a connecting assembly 2, and a lifting assembly 3;

[0030] The screen body 1 is located below the sand washing machine, and the connecting component 2 is used to connect the screen body 1 and the sand washing machine; the lifting component 3 is located at the end of the screen body 1 away from the connecting component 2, and is used to lift the screen body 1.

[0031] The connecting component 2 is a belt 22 structure, and the lifting component 3 includes a wire rope 32 and a ratchet 31.

[0032] Compared to the existing technology where the vibrating screen is bolted to the sand washing machine, generating significant noise, this embodiment uses a belt 22 structure for flexible connection between the sand washing machine and the vibrating screen. This reduces noise and effectively absorbs and buffers vibration transmission between the sand washing machine and the vibrating screen, avoiding vibration superposition caused by rigid connection, reducing component wear, and extending equipment service life.

[0033] Specifically, such as Figure 2 As shown, the sieve body 1 includes a sieve hole structure 11, a frame 13, and a support partition 12.

[0034] A screen structure 11 is located at the bottom of the screen body 1, with screen holes of different diameters for filtering molding sand of different diameters, thereby improving the working efficiency of the vibrating screen. A support partition 12 is provided on the upper part of the screen structure 11, and the support partition 12 is vertically arranged. The support partition 12 can maintain the rigidity of the screen body 1 and prevent the screen body 1 from deforming.

[0035] The outer part of the sieve structure 11 is the frame 13, which is the frame structure of the sieve body 1.

[0036] Furthermore, the two ends of the screen body 1 are at different heights during operation, which facilitates the pouring of molding sand inside the vibrating screen.

[0037] The screen body 1 is provided with a connecting component 2 and a lifting component 3 at both ends, with one end of the lifting component 3 being higher than the end of the connecting component 2.

[0038] The connecting component 2 is used to connect the screen body 1 and the sand washing machine. There are two sets of connecting components 2, which are respectively arranged on both sides of the screen body 1.

[0039] The connecting assembly 2 includes a belt 22 and pulleys 21. Each set of pulleys 21 has two pulleys: a first pulley 21 and a second pulley 21. The first pulley 21 is mounted on the sand washing machine, and the second pulley 21 is mounted outside the frame of the screen body 1. The first pulley 21 and the second pulley 21 are connected by the belt 22. The pulleys 21 are fixed to the sand washing machine and the screen body 1 by pulley 21 fixing plates. During operation, because the pulleys 21 and belt 22 are flexibly connected, compared to a rigid connection, this reduces friction and noise generated by the relative movement between the vibrating screen and the sand washing machine, extends the equipment's service life, and facilitates disassembly and maintenance.

[0040] The lifting assembly 3 includes a ratchet 31 and a wire rope 32. The ratchet 31 is located at the lower part of the screen body 1, and one end of the wire rope 32 is connected to the ratchet 31, while the other end is connected to the screen body 1.

[0041] Furthermore, the lifting assembly 3 also includes a pulley 33. The pulley 33 is mounted on the outer frame of the sand washing machine, and the wire rope 32 is wound around the pulley 33. When lifting the screen body 1, the ratchet 31 is rotated, and the wire rope 32 passes around the pulley 33, with its end driving the screen body 1 to rise or fall, facilitating the picking and placing of the screen body 1.

[0042] In this embodiment, a lifting component 3 is provided at the end of the vibrating screen away from the connecting component 2. The lifting component 3 includes a wire rope 32, a ratchet 31, and a pulley 33. The wire rope 32 is located between the pulley 33 and the ratchet 31, and the ratchet 31 is located below the vibrating screen. The rotation of the ratchet 31 causes the wire rope 32 to drive the pulley 33 and the other end of the vibrating screen to rise and fall. On the one hand, this makes it easy to remove the vibrating screen. On the other hand, through the repeated rising and falling of the vibrating screen, the molding sand in the screen body 1 can be fully vibrated and screened.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
