Description

Technical Field

[0001] This utility model relates to the technical field of resin sand treatment equipment, and in particular to an automatic cleaning device for resin sand screening mechanisms. Background Technology

[0002] Resin sand is widely used in foundry production, and it needs to be screened during use to ensure the quality of the sand particles and facilitate recycling. The screening mechanism is the core equipment for completing this process.

[0003] After prolonged operation, the inner walls of the screening mechanism, especially the hopper and screen sections, will inevitably accumulate a mixture of resin, curing agent, and sand particles. If these residues are not cleaned in time, they will affect screening efficiency and may even clog the equipment, leading to production interruptions.

[0004] Currently, cleaning the interior of these screening facilities largely relies on manual labor. Workers need to stop the machine and then use tools to physically scrape and rinse the interior. This method not only requires a large amount of manpower and is labor-intensive, but also suffers from blind spots and operational dead zones due to the often complex internal structure of the screening facilities. This results in incomplete cleaning, residues easily hardening, and increased difficulty in subsequent cleaning.

[0005] In summary, existing cleaning methods lack automation and efficiency, making it difficult to meet the high standards of equipment maintenance required in modern casting production. There is an urgent need for an automated cleaning device that can automatically extend into the screening mechanism, clean thoroughly, and save manpower.

[0006] Therefore, this utility model proposes an automatic cleaning device for resin sand screening mechanisms to overcome the shortcomings of the prior art. Utility Model Content

[0007] In the existing technology, the cleaning of resin sand screening mechanisms mainly relies on manual labor, which has the problems of high labor intensity, low work efficiency, and difficulty in reaching the inside of the mechanism, resulting in incomplete cleaning. The present invention aims to provide an automatic cleaning device for resin sand screening mechanisms with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an automatic cleaning device for a resin sand screening mechanism, which is used to clean the screening mechanism. The device includes: a support frame; and a hydraulic rod, the output end of which is connected to the support frame.

[0009] The device further includes a first motor fixedly connected to the support frame; a first bevel gear fixedly connected to the output end of the first motor; and a second bevel gear meshing with the first bevel gear.

[0010] Furthermore, the second bevel gear is fixedly connected to a rotating column, which is rotatably mounted on the support frame; a water tray and a rotating disk are fixedly connected to the outer side of the rotating column; and a brush bristle is fixedly connected to the bottom of the rotating disk.

[0011] The rotating column has a hollow structure and is fixedly connected to a rotary joint; the rotary joint is connected to a water pipe, and the interior of the rotating column is connected to the water pan.

[0012] Preferably, the water tray is fixedly connected with nozzles at even intervals.

[0013] Preferably, the water pipe is connected to a water tank, and the water tank is equipped with a water pump.

[0014] Preferably, the water tray is located above the rotating disk.

[0015] Preferably, the lower part of the screening mechanism is fixedly connected to a discharge channel.

[0016] Preferably, a connecting shaft is also fixedly connected to the support frame.

[0017] Preferably, a brush wheel is fitted and rotatably connected to the connecting shaft; the device further includes a second motor, which is fixed to the support frame, and the output end of the second motor drives the brush wheel.

[0018] Preferably, the outer periphery of the brush wheel is fixedly connected with two brush bristles.

[0019] This utility model has the following beneficial effects: 1. In this utility model, by setting up a support frame driven by a hydraulic rod, and a rotating column driven by a first motor and a bevel gear set on the support frame, the rotating column drives the rotating disk and brush to rotate, and at the same time drives the spray nozzle to rotate and spray through the rotary joint and water tray, the problem of the existing technology of relying on manual cleaning of the residue on the inner wall of the screening mechanism, which is inefficient, labor-intensive and incomplete, is solved. It achieves the technical effect of automatically extending into the inside of the mechanism, saving manpower and improving cleaning efficiency.

[0020] 2. In this utility model, by integrating the rotating bristles and the rotating nozzle into the same cleaning assembly to work together, the problem of stubborn deposits being difficult to remove by simply rinsing or brushing in the prior art is solved. This achieves the technical effect of combining mechanical brushing with high-pressure spraying, resulting in stronger cleaning power and more thorough cleaning. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0024] Please refer to Figures 1 to 3 This utility model provides an automatic cleaning device for a resin sand screening mechanism, which aims to solve the problems of manual cleaning of residues on the inner wall of the resin sand screening mechanism, which is inefficient and incomplete.

[0025] like Figure 1 As shown, the resin sand screening mechanism uses an automatic cleaning device to clean the screening mechanism 1, and the lower part of the screening mechanism 1 is fixedly connected to a discharge channel 2.

[0026] like Figure 1 and Figure 2 As shown, the device includes a support frame 4 and a hydraulic rod 3. The output end of the hydraulic rod 3 is connected to the support frame 4. The hydraulic rod 3 drives the support frame 4 to move vertically to extend into the screening mechanism 1.

[0027] like Figure 1 and Figure 3As shown, a first motor 503 is fixedly connected to the support frame 4. A bevel gear 504 is fixedly connected to the output end of the first motor 503. A bevel gear 505 meshes with the first bevel gear 504. A rotating column 507 is fixedly connected to the second bevel gear 505. The rotating column 507 is rotatably mounted on the support frame 4. The rotating column 507 has a hollow structure. A rotary joint 506 is fixedly connected to the rotating column 507. A water pipe 502 is connected to the rotary joint 506. A water tank 501 is connected to the water pipe 502. A water pump is installed inside the water tank 501. A water tray 508 and a rotating disk 510 are fixedly connected to the outside of the rotating column 507. The water tray 508 is located above the rotating disk 510. The inside of the rotating column 507 is connected to the water tray 508. Spray nozzles 509 are fixedly connected at even intervals on the water tray 508. A brush bristle 511 is fixedly connected to the bottom of the rotating disk 510.

[0028] To further enhance the comprehensiveness of the cleaning operation and address the issue of impurities easily adhering to the support frame 4, the automatic cleaning device for this resin sand screening mechanism also includes an auxiliary cleaning component. Please refer to [link / reference needed] for details. Figure 2 The support frame 4 is also fixedly connected to a connecting shaft 601, which serves as the mounting base for the auxiliary cleaning components. Its position cooperates with the rotating column 507 to cover different cleaning areas. A brush wheel 603 is mounted and rotatably connected to the connecting shaft 601. The brush wheel 603 can rotate around the connecting shaft 601. Brush bristles 604 are fixedly connected to the outer circumferential surface of the brush wheel 603. When the brush wheel 603 rotates, the brush bristles 604 rotate accordingly and perform physical friction cleaning on the inner wall of the support frame 4. In order to provide rotational power, the device also includes a second motor 602. The second motor 602 is fixed to the support frame 4, and the output end of the second motor 602 forms a drive connection with the brush wheel 603. This drive connection ensures that when the second motor 602 starts, it can drive the brush wheel 603 to rotate stably on the connecting shaft 601, thereby realizing automatic brushing of the inner side of the support frame 4.

[0029] Based on the above embodiments, the present invention may also include the following preferred technical solutions: In order to improve the coverage and uniformity of the spray, nozzles 509 are fixedly connected at even intervals on the water tray 508; in order to provide power for the clean water source, a water pipe 502 is connected to a water tank 501, and a water pump is provided inside the water tank 501; in terms of structural layout, the water tray 508 is located above the rotating disk 510; and, in order to clarify the working object structure of the device, a discharge channel 2 is fixedly connected to the lower part of the screening mechanism 1.

[0030] Working principle: When the screening mechanism 1 finishes screening and needs to be cleaned, the hydraulic rod 3 is activated. The output end of the hydraulic rod 3 drives the connected support frame 4 to move downward, so that the support frame 4 extends into the interior of the screening mechanism 1.

[0031] After the support frame 4 is lowered into position, the first motor 503 is started. The output end of the first motor 503 is fixedly connected to the first bevel gear 504. The first bevel gear 504 rotates and meshes to drive the second bevel gear 505 to rotate. The second bevel gear 505 is fixedly connected to the rotating column 507, thereby driving the rotating column 507, which is rotatably mounted on the support frame 4, to rotate.

[0032] The rotation of the rotating column 507 causes the rotating disk 510 fixedly connected to its outer side to rotate as well. The brush 511 fixedly connected to the bottom of the rotating disk 510 rotates accordingly, mechanically scrubbing the inner wall of the screening mechanism 1.

[0033] At the same time, the water pump inside the water tank 501 starts, and the water in the water tank 501 is transported to the rotary joint 506 through the water pipe 502. The rotary joint 506 is fixedly connected to the hollow rotating column 507. The water flows into the interior of the rotating column 507 and connects to the water pan 508 located above the rotating disk 510. The water pan 508 rotates together with the rotating column 507, and the water finally sprays out from the nozzles 509 that are evenly spaced and fixedly connected on the water pan 508 to spray and rinse the inner wall of the screening mechanism 1.

[0034] While the screening mechanism 1 is being cleaned, the second motor 602 is started. The second motor 602 is fixed on the support frame 4. The output end of the second motor 602 drives the brush wheel 603. The brush wheel 603 is fitted and rotatably connected to the connecting shaft 601 fixed on the support frame 4. The rotation of the brush wheel 603 drives the brush bristles 604 fixedly connected to its outer periphery to rotate, thereby brushing the inner wall of the support frame 4. The residue generated during the cleaning of the screening mechanism 1 can be discharged through the discharge channel 2 fixedly connected to its lower part.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
