Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of sand and gravel separator technology, and more specifically, to an environmentally friendly and durable sand and gravel separator for concrete preparation. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading waste concrete blocks, mixing them with aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, and then adding cement, water, etc. Recycled concrete can be classified into the following types according to the aggregate combination: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates and fine aggregates are natural sand; coarse aggregates are natural crushed stone or pebbles and fine aggregates are recycled aggregates; recycled aggregates replace part of the coarse aggregates or fine aggregates.

[0003] According to a public disclosure of a recycled concrete sand and gravel separation device (publication number: CN212575824U), it includes a casing, a sand outlet and a stone outlet extending through the side wall along the length of the casing. A through hole is provided on the side wall of the casing through the sand and stone outlets, and a pusher plate for pushing sand and gravel is installed within the through hole. A pushing component for horizontally sliding the pusher plate is also provided within the casing. However, in this device, the interaction of the pusher plate, sand outlet, and stone outlet makes it difficult to simultaneously screen the concrete, spread it evenly, and strike the filter plate. The material is difficult to spread evenly on the filter plate, hindering uniform material distribution, reducing screening accuracy and efficiency, and making it difficult to effectively loosen the material on the screen, thus slowing down the filtration process. This design needs improvement. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide an environmentally friendly and durable sand and gravel separator for concrete preparation, which solves the technical problems in related technologies / prior technologies that make it difficult to simultaneously screen concrete, spread the concrete, and strike the filter plate. The material is difficult to spread evenly on the filter plate, which is not conducive to the uniform distribution of the material, reduces the accuracy and efficiency of screening, makes it difficult to effectively loosen the material on the screen, and makes it difficult to help particles pass through the filter plate, thereby slowing down the filtration process.

[0005] According to one aspect, at least one embodiment of this disclosure provides an environmentally friendly and durable sand and gravel separator for concrete preparation, including a protective shell, wherein a discharge port is provided on the side of the protective shell;

[0006] The protective shell is equipped with a screening device, which includes a motor. The output shaft of the motor is fixedly connected to a reciprocating lead screw. A threaded block is threadedly connected to the circumferential surface of the reciprocating lead screw. A scraper is fixedly connected to the bottom of the threaded block. A slider is fixedly connected to the side of the threaded block. The end of the slider away from the threaded block is slidably connected to the inner wall of the protective shell.

[0007] For example, in at least one embodiment of this disclosure, an environmentally friendly and durable concrete preparation sand and gravel separator is provided, which further includes a screening device comprising a filter structure. The filter structure includes a rotating rod, which is fixedly connected to one end of a reciprocating screw. A disc is fixedly connected to the circumferential surface of the rotating rod, and a fixing block is fixedly connected to the circumferential surface of the disc. A rotating rod extends through the side of the protective shell, and a striking rod is fixedly connected to the circumferential surface of the rotating rod. A gear is fixedly connected to the circumferential surface of the rotating rod, and a filter plate is fixedly connected to the inner wall of the protective shell.

[0008] The gear is located on the movement trajectory of the fixed block, and the filter plate is located on the movement trajectory of the striking rod. The design of the gear and the fixed block is conducive to the rotation of the striking rod, which is beneficial to striking the filter plate.

[0009] A torsion spring is fixedly connected to the circumferential surface of the rotating rod. The end of the torsion spring away from the rotating rod is fixedly connected to the side of the protective shell. The design of the torsion spring helps the striking rod to reciprocate continuously, effectively preventing the filter plate from clogging and making the screening process smoother.

[0010] According to another aspect, at least one embodiment of this disclosure also provides an environmentally friendly and durable concrete preparation sand and gravel separator, including the screening device comprising a feeding structure, the feeding structure comprising a sprocket, the sprocket being fixedly connected to the circumferential surface of a rotating rod, a chain being provided on the side of the sprocket, a chain wheel being provided at the end of the chain away from the chain, a rotating shaft being fixedly connected to the inner wall of the chain wheel, a threaded rod being fixedly connected to one end of the rotating shaft, a threaded sleeve being threadedly connected to the circumferential surface of the threaded rod, a support rod being fixedly connected to the bottom of the threaded sleeve, and a scraper being fixedly connected to the bottom of the support rod.

[0011] For example, in at least one embodiment of this disclosure, an environmentally friendly and durable concrete preparation sand and gravel separator is provided, which further includes the side of the sprocket meshing with the inner wall of the chain, and the side of the chain wheel meshing with the inner wall of the chain.

[0012] The rotating shaft runs through the side of the protective shell, and the torsion spring is initially in a relaxed state. The design of the torsion spring allows the striking rod to automatically reset, reducing manual intervention.

[0013] A limiting rod extends through the side of the threaded sleeve, and one end of the limiting rod is fixedly connected to the inner wall of the protective shell. The design of the limiting rod can limit the threaded sleeve, thereby increasing the stability of the device.

[0014] The protective shell is provided with support legs on its side, and a feeding plate is fixedly connected to the top of the support legs. The feeding plate is designed to allow materials to enter the inner wall of the protective shell in an orderly manner.

[0015] The number of limiting rods is set to several, and they are arranged in a circumferential array on the side of the threaded sleeve. The displacement of the threaded sleeve is limited by the limiting rods on its side, ensuring that the movement of the threaded sleeve will not exceed the predetermined range.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, a reciprocating screw driven by a motor rotates in conjunction with components such as a fixed block, rotating rod, and rotary rod in the screening device. This achieves the effect of rotating rod driving a striking rod to rotate, which then strikes the filter plate. When the fixed block moves away from the gear, the rotating rod drives the striking rod to reset through the elastic force of a torsion spring, causing the striking rod to continuously strike the filter plate. This achieves the effect of simultaneously screening concrete, leveling the concrete, and striking the filter plate. The material can be evenly spread on the filter plate, which helps to ensure uniform material distribution, improves screening accuracy and efficiency, and effectively loosens the material on the screen, helping particles pass through the filter plate, thereby accelerating the filtration process.

[0018] 2. In this disclosure, the force that drives the sprocket to rotate through the rotating rod cooperates with the support rod, limiting rod, and threaded sleeve in the screening device. This achieves the effect of limiting the threaded sleeve through the limiting rod on the side of the threaded sleeve, then displacing the threaded sleeve to drive the support rod to move, which in turn drives the scraper to move, and finally pushing the screened concrete out of the discharge port through the scraper's displacement. This achieves the effect of automatic feeding, automatically pushing the screened concrete out of the discharge port, thus avoiding the trouble of manual cleaning and handling, making the whole process smoother and more efficient.

Detailed Implementation

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-6 As shown, it illustrates an environmentally friendly and durable concrete preparation sand and gravel separator according to an embodiment of the present disclosure, including a protective shell 101, and a discharge port 104 is provided on the side of the protective shell 101.

[0034] The protective shell 101 is equipped with a screening device 2, which includes a motor 201. The output shaft of the motor 201 is fixedly connected to a reciprocating lead screw 202. A threaded block 203 is threadedly connected to the circumferential surface of the reciprocating lead screw 202. A scraper 205 is fixedly connected to the bottom of the threaded block 203. A slider 204 is fixedly connected to the side of the threaded block 203. The end of the slider 204 away from the threaded block 203 is slidably connected to the inner wall of the protective shell 101.

[0035] In some examples, the screening device 2 includes a filtering structure, which includes a rotating rod 206 fixedly connected to one end of a reciprocating screw 202. A disc 207 is fixedly connected to the circumferential surface of the rotating rod 206, and a fixing block 208 is fixedly connected to the circumferential surface of the disc 207. A rotating rod 209 extends through the side of the protective shell 101. A striking rod 215 is fixedly connected to the circumferential surface of the rotating rod 209, and a gear 210 is fixedly connected to the circumferential surface of the rotating rod 209. A filter plate 216 is fixedly connected to the inner wall of the protective shell 101.

[0036] The gear 210 is located on the movement trajectory of the fixed block 208, and the filter plate 216 is located on the movement trajectory of the striking rod 215. The design of the gear 210 and the fixed block 208 is conducive to the rotation of the striking rod 215, which is conducive to striking the filter plate 216.

[0037] A torsion spring 211 is fixedly connected to the circumferential surface of the rotating rod 209. The end of the torsion spring 211 away from the rotating rod 209 is fixedly connected to the side of the protective shell 101. The design of the torsion spring 211 is conducive to the continuous reciprocating motion of the striking rod 215, effectively preventing the filter plate 216 from clogging and making the screening process smoother.

[0038] For example, such as Figures 1-6 As shown, this application uses a motor 201 to drive a reciprocating screw 202 to rotate, which in turn causes the threaded block 203 to move. A limiting rod 220 on the side of the threaded block 203 limits its movement. The displacement of the threaded block 203 then causes the scraper 205 to move, leveling the material on the top of the filter plate 216. The rotation of the reciprocating screw 202 drives a rotating rod 206 to rotate, which in turn drives a disc 207 to rotate. The rotation of the disc 207 then drives a fixed block 208. The mechanism rotates, and then the fixed block 208 squeezes the gear 210, causing the gear 210 to drive the rotating rod 209 to rotate. The rotation of the rotating rod 209 drives the striking rod 215 to rotate, and the striking rod 215 strikes the filter plate 216. When the fixed block 208 moves away from the gear 210, the rotating rod 209 drives the striking rod 215 to reset through the elastic force of the torsion spring 211, so that the striking rod 215 continuously strikes the filter plate 216. This achieves the effect of screening concrete, leveling the concrete and striking the filter plate 216 at the same time, preventing the filter plate 216 from clogging and accelerating the filtration speed.

[0039] like Figures 1-6 As shown, this invention illustrates an environmentally friendly and durable concrete preparation sand and gravel separator according to another embodiment of the present disclosure. The screening device 2 includes a feeding structure, which includes a sprocket 212. The sprocket 212 is fixedly connected to the circumferential surface of the rotating rod 209. A chain 213 is provided on the side of the sprocket 212. A chain wheel 214 is provided at the end of the chain 213 away from the chain 213. A rotating shaft 217 is fixedly connected to the inner wall of the chain wheel 214. A threaded rod 218 is fixedly connected to one end of the rotating shaft 217. A threaded sleeve 219 is threadedly connected to the circumferential surface of the threaded rod 218. A support rod 221 is fixedly connected to the bottom of the threaded sleeve 219. A scraper 222 is fixedly connected to the bottom of the support rod 221.

[0040] In some examples, the side of sprocket 212 meshes with the inner wall of chain 213, and the side of sprocket 214 meshes with the inner wall of chain 213.

[0041] The rotating shaft 217 runs through the side of the protective shell 101. The torsion spring 211 is initially in a relaxed state. The design of the torsion spring 211 allows the striking rod 215 to automatically reset, reducing manual intervention.

[0042] A limiting rod 220 passes through the side of the threaded sleeve 219. One end of the limiting rod 220 is fixedly connected to the inner wall of the protective shell 101. The design of the limiting rod 220 can limit the threaded sleeve 219, increasing the stability of the device.

[0043] The protective shell 101 has a support leg 102 on its side, and a feeding plate 103 is fixedly connected to the top of the support leg 102. The feeding plate 103 is designed to allow materials to enter the inner wall of the protective shell 101 in an orderly manner.

[0044] The number of limiting rods 220 is set to several, and they are arranged in a circumferential array on the side of the threaded sleeve 219. The displacement of the threaded sleeve 219 is limited by the limiting rods 220 on its side, ensuring that the movement of the threaded sleeve 219 will not exceed the predetermined range.

[0045] For example, such as Figures 1-6 As shown, the rotation of the rotating rod 206 drives the sprocket 212 to rotate, which in turn drives the chain 213 to rotate. The chain 213 then drives the chain wheel 214 to rotate, which in turn drives the rotating shaft 217 to rotate. The rotating shaft 217 then drives the threaded rod 218 to rotate, which in turn drives the threaded sleeve 219 to move. The threaded sleeve 219 is then limited by the limiting rod 220 on its side. The movement of the threaded sleeve 219 then drives the support rod 221 to move, which in turn drives the scraper 222 to move. The movement of the scraper 222 pushes the screened concrete out of the discharge port 104, thus achieving automatic material feeding.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
