Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collection device technology, and more specifically, to a dust collection cover for a sand bucket. Background Technology
[0002] In the foundry industry, in a certain intermediate ladle process, it is necessary to take out or pour sand from the sand bucket. When workers take out or pour sand, dust is generated. Generally, it is necessary to use a suction hood to absorb the dust.
[0003] Traditional sand bucket vacuums have the following drawbacks: They are relatively large, primarily to ensure sufficient suction coverage and adsorption capacity. However, this design also presents a significant disadvantage: limited mobility. Due to their size and weight limitations, moving the vacuum to different work areas often requires multiple workers or specialized handling equipment, undoubtedly increasing operational complexity and time costs.
[0004] Especially in industries like foundry where frequent sand handling is required, the inconvenience of moving the suction hood is a significant issue. Workers need to move the hood back and forth between different sand buckets to remove dust during sand collection or dumping. The traditional sand bucket suction hood, due to its bulky nature, negatively impacts overall work efficiency. Therefore, improvements are needed. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a sand bucket suction cover, which has the advantage of being easy to use.

[0009] As a preferred embodiment of this utility model, a limiting ring is fixedly installed on the outer side of the circular shaft, and the limiting ring is located on the rear side of the circular ring block.
[0010] As a preferred embodiment of this utility model, a handle is fixedly installed above the rear end of the sand bucket, and a handle is fixedly installed above the front end of the sand bucket.
[0011] As a preferred embodiment of this utility model, a limiting block is fixedly installed inside the movable groove on the inner side of the curved block, and a rectangular plate is movably installed inside the movable groove on the inner side of the limiting block. A return spring is elastically installed between the inner side of the rectangular plate and the inner side of the movable groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model allows the suction cup to be lifted by pulling the handle upwards, and then the foot pedal to be stepped down. At this time, the curved block is compressed by the positioning ring and retracts into the movable groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6 As shown, this utility model provides a sand bucket suction cover, including a sand bucket 1, a suction cover 2 is provided on the outside of the sand bucket 1, a first protrusion 6 and a second protrusion 8 are fixedly installed on both sides of the front end of the suction cover 2, a round shaft 7 is rotatably installed on the inside of the first protrusion 6, a circular ring block 9 is fixedly installed on the outside of the circular shaft 7, a universal shaft 10 is fixedly installed on the outside of the circular ring block 9, a short shaft 11 is fixedly installed on the inside of the universal shaft 10, a movable wheel 12 is movably sleeved on the outside of the short shaft 11, a connecting plate 26 is fixedly installed on the outside of the sand bucket 1, a positioning ring 13 is fixedly installed on the front end of the connecting plate 26 and movably sleeved on the outside of the circular shaft 7, the positioning ring 13 is located on the front side of the circular ring block 9, a movable groove 15 is opened inside the circular ring block 9, and slots 16 are opened on the inner sides of both ends of the positioning ring 13, and a curved block 17 extending into the slot 16 is movably installed inside the movable groove 15.
[0024] When it is necessary to move the suction cup 2, first stand on one side of the suction cup 2, hold the handle 25 with one hand, and then pull the handle 25 upward to lift the suction cup 2. Then, step on the foot pedal 23 downward to make the foot pedal 23 drive the cylindrical block 22 to rotate. The cylindrical block 22 drives the circular shaft 7 to rotate, and the circular shaft 7 drives the circular ring block 9 to rotate. At this time, the curved block 17 is squeezed by the positioning ring 13 and shrinks into the movable groove 15, causing the return spring 20 to deform under the squeezing force. When the circular ring block 9 drives the moving wheel 12 to rotate to the lower position, the return spring 20 releases its elastic potential energy to push the curved block 17 into the lower slot 16, thereby fixing the moving wheel 12. Then, push the handle 24 to move the suction cup 2.
[0025] Pull the suction cup 2 up by pulling the handle 25 upwards, and then step down on the foot pedal 23. At this time, the curved block 17 is compressed by the positioning ring 13 and retracts into the movable groove 15. When the ring block 9 drives the moving wheel 12 to rotate downwards, the return spring 20 releases its elastic potential energy to push the curved block 17 into the lower slot 16, thereby fixing the moving wheel 12. Compared with the traditional sand bucket suction cup, this sand bucket suction cup has a retractable moving wheel 12, which makes it easy for staff to move the suction cup 2. After moving it to the designated position, it is easy to retract the moving wheel 12, making it convenient to use.
[0026] Among them, a U-shaped notch 5 is provided at the top front end of the suction hood 2, which corresponds to the sand bucket 1. Slit-shaped dust suction ports 4 are provided on both sides of the suction hood 2, which correspond to the suction pipe 3.
[0027] The suction cup 2 is generally trapezoidal with a U-shaped notch 5. A slit-shaped dust suction port 4 is opened on the side of the suction cup 2. When in use, the whole thing is placed on the sand bucket 1. Workers take it out or pour sand in through the U-shaped notch 5.
[0028] By setting the opening above the suction hood 2 to a U-shaped structure, it does not obstruct the worker's view or affect the worker's operation; secondly, the slotted dust suction port 4 is opened near the dust generation point, and no dust suction ports are opened in other parts, which reduces the collected air volume and saves the power of the enterprise's dust collection system; then, compared with a large dust suction port, the slotted dust suction port 4 has a faster cross-sectional wind speed, and its dust collection effect is better for sandy dust with a certain speed.
[0029] Among them, the front end of the round shaft 7 is fixedly installed with a rotating shaft 21 that passes through the second protrusion 8, the front end of the rotating shaft 21 is fixedly installed with a cylindrical block 22, and the outer side of the cylindrical block 22 is fixedly installed with a foot pedal 23.
[0030] Stepping on the foot pedal 23 causes the foot pedal 23 to rotate the cylindrical block 22, which in turn causes the cylindrical block 7 to rotate, which in turn causes the cylindrical block 7 to rotate the annular block 9. At this time, the curved block 17 is compressed by the positioning ring 13 and shrinks into the interior of the movable groove 15.
[0031] Among them, a limiting ring 14 is fixedly installed on the outer side of the circular shaft 7, and the limiting ring 14 is located on the rear side of the circular block 9.
[0032] By installing the limiting ring 14 on the inner side of the circular block 9, the limiting ring 14 limits the circular block 9, thereby limiting the circular block 9.
[0033] Among them, a handle 24 is fixedly installed on the upper rear end of the sand bucket 1, and a handle 25 is fixedly installed on the upper front end of the sand bucket 1.
[0034] Pulling handle 25 lifts the suction cup 2, and pushing handle 24 moves the suction cup 2.
[0035] Among them, a limiting block 18 is fixedly installed on the inner side of the curved block 17 and located inside the movable groove 15. A rectangular plate 19 is movably installed inside the movable groove 15 and located inside the limiting block 18. A return spring 20 is elastically installed between the inner side of the rectangular plate 19 and the inner side of the movable groove 15.
[0036] The curved block 17 is compressed by the positioning ring 13 and shrinks into the interior of the movable groove 15, causing the return spring 20 to deform under the compression force. When the ring block 9 drives the moving wheel 12 to rotate downward, the return spring 20 releases its elastic potential energy to push the curved block 17 into the lower end of the slot 16, thereby fixing the moving wheel 12.
[0037] Working principle and usage process of this utility model:
[0038] When it is necessary to move the suction cup 2, first stand on one side of the suction cup 2, hold the handle 25 with one hand, and then pull the handle 25 upward to lift the suction cup 2. Then, step on the foot pedal 23 downward to make the foot pedal 23 drive the cylindrical block 22 to rotate. The cylindrical block 22 drives the circular shaft 7 to rotate, and the circular shaft 7 drives the circular ring block 9 to rotate. At this time, the curved block 17 is squeezed by the positioning ring 13 and shrinks into the movable groove 15, causing the return spring 20 to deform under the squeezing force. When the circular ring block 9 drives the moving wheel 12 to rotate to the lower position, the return spring 20 releases its elastic potential energy to push the curved block 17 into the lower slot 16, thereby fixing the moving wheel 12. Then, push the handle 24 to move the suction cup 2.
[0039] The suction cup 2 is generally trapezoidal with a U-shaped notch 5. A slit-shaped dust suction port 4 is opened on the side of the suction cup 2. When in use, the whole thing is placed on the sand bucket 1. Workers take it out or pour sand in through the U-shaped notch 5.
