Description

Technical Field

[0001] The utility model belongs to the technical field of recycling and screening equipment, and particularly relates to a recycling and screening mechanism for foundry auxiliary materials. Background Art

[0002] Recycled foundry sand refers to the waste generated during the foundry production process, which is sand material reused after recycling treatment. Before recycling treatment, it needs to be screened by a screening mechanism. When the existing recycling and screening mechanism for foundry auxiliary materials is in use, generally, an electric motor drives the recycling and screening machine to vibrate and screen on the base. Due to the moving rollers on the base of the recycling and screening machine without any positioning structure, during the vibration screening process, it may drive the moving rollers to displace and roll, thus preventing the recycling and screening machine from stably screening. For this reason, we propose a recycling and screening mechanism for foundry auxiliary materials. Content of the Utility Model

[0003] The purpose of the utility model is to provide a recycling and screening mechanism for foundry auxiliary materials to solve the problem that there is no stable limiting structure on the base of the recycling and screening machine, which may cause the rollers at the bottom of the recycling and screening machine to displace as mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A recycling and screening mechanism for foundry auxiliary materials, including a recycling and screening machine. The bottom end of the recycling and screening machine is connected with a base. The bottom end of the base is symmetrically fixed with moving rollers. A stable limiting mechanism is arranged at the bottom end of the base. A holding and pulling mechanism is arranged on one side of the recycling and screening machine. The stable limiting mechanism includes: a limiting component arranged at the bottom end of the base; a lockable guiding component arranged between the limiting component and the inner side of the base; an adjusting component arranged at the top end of the base and connected with the limiting component.

[0005] Preferably, the limiting component includes a built-in groove opened at the bottom end of the base and a limiting plate arranged inside the built-in groove. The limiting plate is snap-connected with the built-in groove. A rubber pad is fixed at the bottom end of the limiting plate.

[0006] Preferably, the lockable guiding component includes guiding grooves symmetrically opened at the top end inner wall of the built-in groove and guiding rods symmetrically fixed at the top end of the limiting plate. The guiding rods are slidably connected with the guiding grooves.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4 For this utility model, a technical solution is provided: a casting auxiliary material recycling and screening mechanism, including a recycling and screening machine 1. The bottom end of the recycling and screening machine 1 is connected to a base 2. The bottom end of the base 2 is symmetrically fixed with moving rollers 3. A stable limiting mechanism is arranged at the bottom end of the base 2. A holding and pulling mechanism is arranged on one side of the recycling and screening machine 1. The stable limiting mechanism includes: a limiting component arranged at the bottom end of the base 2; a lockable guiding component arranged between the limiting component and the inner side of the base 2; and an adjusting component arranged at the top end of the base 2 and connected to the limiting component.

[0020] In this embodiment, preferably, the limiting component includes an internal groove 100 opened at the bottom end of the base 2 and a limiting plate 101 arranged inside the internal groove 100. The limiting plate 101 is engaged with the internal groove 100. A rubber pad 102 is fixed at the bottom end of the limiting plate 101. When the rubber pad 102 at the bottom end of the limiting plate 101 fits with the ground, it can firmly limit the base 2.

[0021] In this embodiment, preferably, the lockable guiding component includes guiding grooves 200 symmetrically opened at the top end inner wall of the internal groove 100 and guiding rods 201 symmetrically fixed at the top end of the limiting plate 101. By sliding the guiding rods 201 in the guiding grooves 200, it is convenient to play a guiding role when the limiting plate 101 moves.

[0022] In this embodiment, preferably, a locking hole 300 penetrating through the surface of the base 2 to the inside of the guiding groove 200 is opened. A locking screw 301 screwed to the locking hole 300 is arranged on the surface of the base 2. The end of the locking screw 301 is in pressing fit with the surface of the guiding rod 201, which can position the position of the guiding rod 201 inside the guiding groove 200.

[0023] In this embodiment, preferably, the adjusting component includes a screw hole 400 penetrating through the top end of the base 2 and connected to the internal groove 100. An adjusting screw 401 screwed to the screw hole 400 is arranged at the top end of the base 2. A bearing 402 is connected between the bottom end of the adjusting screw 401 and the limiting plate 101, and the position of the limiting plate 101 can be adjusted.

[0024] In this embodiment, preferably, a hand crank 500 is fixed at the top end of the adjusting screw 401, which can easily rotate the adjusting screw 401 to rotate inside the screw hole 400.

[0025] In this embodiment, preferably, the holding and pulling mechanism includes a pulling handle 600 fixed on one side of the recycling and screening machine 1 and a rubber ring 601 sleeved on the surface of the pulling handle 600, which is convenient for holding and pulling the recycling and screening machine 1 to move.

[0026] Working principle and usage process of the utility model: When the utility model is pulled by holding the handle 600, and the rubber ring 601 plays a role in anti-slip during holding, when pulling the recycling screening machine 1 to move through the moving rollers 3, after the movement is completed, stop pulling the recycling screening machine 1. Then loosen the locking screw 301 so that its end separates from the surface of the guide rod 201 and is screwed into the interior of the locking hole 300 to release the positioning of the guide rod 201. Subsequently, rotate the adjusting screw 401 by the handwheel 500 so that it rotates inside the screw hole 400, and push the limiting plate 101 to move downward from the interior of the built-in groove 100 through the bearing 402. At the same time, drive the guide rod 201 to slide inside the guide groove 200 to play a role in moving guidance. When the rubber pad 102 at the bottom of the limiting plate 101 is in close contact with the ground, the moving rollers 3 can be supported and positioned to avoid the displacement of the moving rollers 3 when the recycling screening machine 1 vibrates and screens. Then tighten the locking screw 301 so that it rotates inside the locking hole 300 and its end presses against and fits with the surface of the guide rod 201, and the position of the guide rod 201 can be locked and fixed to complete the work of fixed limit.
