Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a broken sand collecting device for a shakeout machine. Background Technique

[0002] In the process of casting production, after the castings are poured and cooled, they need to be separated from the sand mold tooling. The shakeout machine vibrates to separate the castings from the sand mold, and then the castings are taken out from the sand mold tooling. It is easy to separate the sand mold on the outer shape of the casting, but for the sand in the inner cavity of the casting, a part of the sand can flow out through the holes, but not all of it can flow out. At this time, it is necessary to lift the casting out of the shakeout machine and manually dig out the sand outside. The dug-out sand needs to be transported to the shakeout machine again by manual labor for the operation of the subsequent process, which greatly increases the labor intensity of workers and reduces work efficiency.

[0003] Therefore, we propose a broken sand collecting device for a shakeout machine to facilitate solving the problems raised above. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems mentioned above.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A broken sand collecting device for a shakeout machine includes a plurality of first support seats and two second support seats installed on the ground. Every two first support seats are arranged opposite to each other, and a rotating roller is rotatably installed between the two opposite first support seats and the two second support seats respectively. One end of one of the rotating rollers is installed with a driving structure, and the same conveyor belt is installed on the plurality of rotating rollers in a driving manner. A screening plate for placing the casting is installed directly above the feeding end of the conveyor belt, and the sand and gravel falling from the casting directly fall onto the conveyor belt through the screening plate, and the sand and gravel are conveyed to a designated position by the conveyor belt for collection.

[0006] Further: The driving structure includes a mounting plate installed below the conveyor belt and a motor installed on the mounting plate. The output shaft of the motor is installed with a driving wheel, and the output shaft of the driving wheel is connected to a driven wheel installed at the end of one of the rotating rollers through a conveyor belt for transmission.

[0007] Further: Support legs are installed at the corners of the bottom of the screening plate, and the plurality of support legs are fixed on the ground.

[0008] Further: A funnel is arranged below the screening plate, and the discharge port of the funnel is located directly above the conveyor belt.

[0009] Further: A tension adjustment assembly is arranged at the connection between the rotating roller and the second support seat.

[0010] Further: The tightness adjustment assembly includes an adjustment plate rotatably mounted at the end of the rotating roller. A plurality of sliding grooves are formed in the adjustment plate. A pin shaft slidably mounted in the sliding groove is fixed on the second support seat. An adjustment seat is fixed on the outer side of the adjustment plate. An adjustment bolt is threadedly mounted on the adjustment seat and is rotatably connected to the side wall of the second support seat.

[0011] Advantages of the present utility model:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0019] Embodiments of the present utility model:

[0020] A sand crushing and collecting device for a shakeout machine, comprising a number of first support seats 1 and a number of second support seats 2. Every two first support seats 1 are arranged oppositely, and two second support seats 2 are also arranged oppositely. A rotating roller 3 is rotatably installed between the two opposed first support seats 1. At the tops of the two second support seats 2, a tension adjustment assembly 9 is installed, and a rotating roller 3 is also rotatably installed between the two tension adjustment assemblies 9. Through the setting of the tension adjustment assembly 9, the tension of the conveyor belt 5 can be adjusted. And the same conveyor belt 5 is drivingly installed on a plurality of rotating rollers 3. Through the setting of the conveyor belt 5, it plays a role in conveying the sand and gravel. A driving structure is installed below the conveyor belt 5, and the driving structure is connected to the rotating roller 3 at the end. Through the setting of the driving structure, it plays a role in driving the conveyor belt 5.

[0021] Above the feeding end of the conveyor belt 5, a screening plate 6 is installed. Through the setting of the screening plate 6, the casting can be placed on the screening plate 6, so that the sand and gravel on the casting can directly fall onto the conveyor belt 5 and be conveyed to the designated position by the conveyor belt 5, reducing the process of the staff putting the sand and gravel onto the conveyor belt 5 and reducing the labor intensity of the staff. And support legs 7 are installed at the corners of the bottom of the screening plate 6. Through the setting of the support legs 7, it plays a role in supporting the screening plate 6. A funnel 8 is installed at the bottom of the screening plate 6. Through the setting of the funnel 8, the sand and gravel can directly fall onto the conveyor belt 5 through the funnel 8, reducing the sand and gravel from falling outside the conveyor belt 5.
