Description

Technical Field

[0001] The utility model relates to the technical field of sand material recovery for sand casting, in particular to a sand mold vibrating table for alloy steel sand casting. Background Art

[0002] During the sand casting process, alloy steel grit, as part of the molding sand, effectively supports and secures the shape of the casting, preventing deformation or displacement of the molten metal during solidification. Its high strength and excellent thermal conductivity ensure the stability and accuracy of the casting quality. After casting, a vibrating shakeout machine is used to separate the alloy steel grit from the casting and recycle it.

[0003] In the related art, a search revealed a solution for a sand casting sand recovery device (Announcement No. CN22145426U), which pours the casting sand into a recovery box. At this time, the sand is guided into a vibrating screening assembly through two guide inclined plates on the upper part of the recovery box. The casting sand is vibrated and screened by the vibrating screening assembly, and qualified fine powder raw materials fall to the bottom of the recovery box through the vibrating screening assembly. The casting sand raw materials that have not been completely ground remain in the vibrating screening assembly and continue to be vibrated and screened until they become fine powder and fall into the recovery box for collection and subsequent use.

[0004] However, the above solution is prone to dust problems when the casting sand raw materials are crushed by grinding, which will lead to an increase in dust content in the working environment, making subsequent cleaning more troublesome, and the dust is not good for the health of the workers. Utility Model Content

[0005] The purpose of the utility model is to provide a sand mold vibrating table for alloy steel sand casting to solve the problems raised in the above background technology.

[0009] A vacuum cleaner is installed on the surface of the crushing box and is connected to the filter box. The vacuum cleaner can be used to extract dust from the crushed alloy steel sand, reduce dust, and protect the working environment and the health of workers.

[0010] Furthermore, the crushing assembly includes a motor and two rollers, which are driven and installed inside the crushing box and are driven by two gears. The motor is installed on the side of the crushing box and is connected to one of the rollers. The surface of the roller is provided with a plurality of teeth, and the teeth on the surfaces of the two rollers are staggered. The agglomerated alloy steel sand can be fully crushed, and the teeth crush the alloy steel sand, making it convenient to recover the alloy steel sand.

[0011] Furthermore, a guide hopper is installed on the lower end face of the vibrating sand machine, the bellows is sleeved on the lower end of the guide hopper, the lower end face of the crushing box is provided with a discharge hopper, the filter box is connected to the surface of the discharge hopper, and the inside of the filter box has a slope, which can prevent alloy steel sand from accumulating on the middle surface of the filter box.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-3 The utility model provides a technical solution: a sand vibrating table for alloy steel sand casting, comprising a bracket 1, a sand vibrating machine 2 is installed on the upper part of the bracket 1, a bellows 4 is installed at the end of the sand vibrating machine 2, and the bracket 1 supports the sand vibrating machine 2 at a high position, leaving space for installing a crushing box 5;

[0023] The crushing box 5 is located below the bellows 4 and is connected to the bellows 4. The flexible connection of the bellows 4 ensures that the vibrating sand machine 2 does not cause the crushing box 5 to vibrate, thereby reducing the wear of the crushing box 5. The crushing box 5 is equipped with a crushing assembly for crushing agglomerated alloy steel sand.

[0024] Filter box 9, two filter boxes 9 are provided and are connected to the crushing box 5, a filter plate 13 is plugged into the surface of the filter box 9, a handle 16 is rotatably connected to the surface of the filter box 9, a threaded tube 17 is screwed on the surface of the handle 16, a spring 18 is installed on the inner wall of the threaded tube 17, the spring 18 is connected to a top column 19, the top column 19 presses against the filter plate 13, the filter plate 13 can block the alloy steel grit from passing through, thereby preventing the alloy steel grit from entering the vacuum cleaner 8, and the recovery rate of the alloy steel grit is high;

[0025] The dust collector 8 is installed on the surface of the crushing box 5 and is connected to the filter box 9. The dust collector 8 collects dust to prevent the dust from spreading into the environment.

[0026] In this embodiment, if Figure 2As shown, the crushing assembly includes a motor 6 and two rollers 22. The two rollers 22 are driven and installed inside the crushing box 5 and are engaged and driven by two gears 7. The motor 6 is installed on the side of the crushing box 5 and is connected to one of the rollers 22. When the motor 6 drives one roller 22 to rotate, the two rollers 22 are rotated simultaneously through the two gears 7. When the agglomerated alloy steel sand falls between the two rollers 22, the alloy steel sand can be crushed.

[0027] In this embodiment, if Figure 2 As shown, a plurality of teeth 12 are provided on the surface of the roller 22 , and the teeth 12 on the surfaces of the two rollers 22 are arranged in a staggered manner. The teeth 12 can improve the crushing efficiency of the rollers 22 .

[0028] In this embodiment, if Figure 1 and Figure 3 As shown, the lower end face of the vibrating sand machine 2 is equipped with a guide bucket 3 to ensure that the alloy steel sand will not remain in the vibrating sand machine 2. The bellows 4 is sleeved on the lower end of the guide bucket 3. The lower end face of the crushing box 5 is provided with a discharge bucket 11. The filter box 9 is connected to the surface of the discharge bucket 11. The filter box 9 has an inclined surface inside, and some of the alloy steel sand entering the filter box 9 can slide along the inclined surface into the filter box 9.

[0029] In this embodiment, if Figure 1 and Figure 3 As shown, the upper surface of the filter box 9 is connected to the vacuum cleaner 8 through a bifurcated tube 10, and a valve 21 is installed on the bifurcated tube 10. By opening the two valves 21, the filter boxes 9 can be used at the same time. When the filter plate 13 needs to be cleaned, the corresponding valve 21 can be closed without affecting the dust reduction effect.

[0030] In this embodiment, if Figure 3 As shown, the surface of the filter box 9 is provided with a cannula 15, the handle 16 is rotatably connected to the cannula 15, and the surface of the threaded tube 17 is fixedly connected with a rotating handle 20. It is more convenient to use the rotating handle 20 to drive the threaded tube 17 to rotate, so that the sealing strip 14 can better press against the discharge bucket 11.

[0031] In this embodiment, if Figure 1 and Figure 3 As shown, a sealing strip 14 is installed on the side of the filter plate 13. When the threaded tube 17 is twisted, the threaded tube 17 squeezes the spring 18, and the spring 18 presses against the filter plate 13 through the top column 19. The filter plate 13 makes the sealing strip 14 abut against the discharge bucket 11, and the sealing effect is good, which can prevent the alloy steel sand from passing through the filter plate 13.

[0032] Specifically, when in use, the casting with alloy steel grit is placed in the vibrating sand machine 2. The vibrating sand machine 2 separates the alloy steel grit and the casting by vibration. The alloy steel grit falls into the crushing box 5 through the bellows 4. The motor 6 drives the teeth 12 to rotate through the roller 22. The teeth 12 crush the agglomerated alloy steel grit, thereby fragmenting the alloy steel grit. When the alloy steel grit is crushed, the dust collector 8 extracts the dust generated by the crushing of the alloy steel grit through the bifurcated pipe 10 and the filter box 9. The filter plate 13 blocks the alloy steel grit from entering the vacuum cleaner 8, preventing dust from being raised while not extracting the alloy steel grit. The crushed alloy steel grit leaks out of the discharge hopper 11.

[0033] When the filter plate 13 needs to be cleaned, the corresponding valve 21 is closed. At this time, the other filter box 9 can still be used without delaying dust collection. The threaded tube 17 is loosened by turning the handle 20 so that the top column 19 is no longer tightly against the filter plate 13. Then, the handle 16 is turned to drive the top column 19 to stagger with the filter plate 13, and the filter plate 13 is pulled out of the filter box 9 for cleaning.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
