Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a screening mechanism of an environmentally friendly mobile construction waste land restoration machine. Background Art

[0002] Construction waste is solid waste generated during the construction, reconstruction, expansion or demolition of buildings. According to the different sources of construction waste, it can be divided into construction waste and demolition waste. Construction waste has a wide range of erosion effects on our living environment. If we ignore construction waste for a long time, it will have a bad impact on urban environmental sanitation, living conditions, land quality assessment, etc. First of all, a large amount of land piled with construction waste will reduce the quality of the soil and reduce the production capacity of the soil; construction waste piled in the air will affect the air quality, and some dust particles will be suspended in the air, which is harmful to human health; during the stacking process of construction waste, long-term accumulation will cause harmful substances in construction waste to penetrate into the underground waters and pollute the water environment; if construction waste is piled in the city, it will be detrimental to the urban environment and aesthetics; the stacking of construction waste may have certain safety hazards, and some accidents may occur at any time.

[0003] Nowadays, land remediation machines are mostly used to screen construction waste. In addition to stones, current construction waste also contains a lot of waste plastic bags and iron objects. The screening mechanism of existing land remediation machines is unable to screen waste plastic bags and iron objects. Summary of the invention

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art: in addition to stones, current construction waste also includes a lot of waste plastic bags and iron objects. The screening mechanism of the existing land remediation machine cannot screen the waste plastic bags and iron objects, and a screening mechanism of an environmentally friendly mobile construction waste land remediation machine is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A screening mechanism of an environmentally friendly mobile construction waste land restoration machine comprises two mounting side plates and also includes:

[0007] A primary screening assembly, the primary screening assembly comprising a primary screening plate mounted on the upper end of the mounting side plate and used for screening the waste gas bag;

[0008] A secondary screening assembly, the secondary screening assembly comprising a secondary screening plate installed between two mounting side plates and located below the primary screening assembly, one end of the secondary screening plate being rotatably connected to the mounting side plate, and the other end of the secondary screening plate being connected to the mounting side plate via a vibration assembly;

[0009] A three-stage screening assembly comprises a three-stage screening plate installed between two installation side plates.

[0010] Preferably, the first-level screening component also includes strip grooves symmetrically opened laterally on the first-level screening plate, a rotatable rotating plate is installed in each of the strip grooves, a plurality of intercepting pins arranged in an L shape are installed on both sides of the rotating plate, each of the intercepting pins is provided with a barb facing inward for rotationally cooperating with the rotating plate, and each of the barbs is provided with a plurality of sharp needles for cooperating therewith.

[0011] Preferably, the secondary screening assembly also includes a protective plate fixedly connected to the primary screening plate and opening downwardly, a rotating disk for providing centrifugal force is rotatably connected inside the protective plate, a rotating shaft vertically arranged with the protective plate is installed at the center of the rotating disk, a cross pin integrally formed with the top of the rotating shaft is installed, a detachable and matching mounting sleeve is clamped on the cross pin, a plurality of rotating blades are threadedly connected to the outer side of the mounting sleeve, and two magnets are symmetrically installed in each of the rotating blades.

[0012] Preferably, the plurality of rotating blades are located in planes at different heights and are staggered.

[0013] Preferably, the vibration assembly includes a limiting column connected at the corner of the first-level screening plate and allowing the first-level screening plate to slide up and down, the limiting column is equipped with an upper mounting disc embedded in the lower plane of the first-level screening plate and a lower mounting disc fixedly connected to the limiting column, and the opposing surfaces of the lower mounting disc and the limiting column are provided with recesses and protrusions that match each other and allow the upper mounting disc to move up and down.

[0014] Preferably, a second connecting plate arranged in an inclined manner and a first connecting plate arranged in a triangular prism shape are also installed in the first-level screening plate.

[0015] Preferably, the three-stage screening device further comprises a plurality of adjustment components installed in the three-stage screening plate, and the three-stage screening plate is installed with rods through the adjustment components.

[0016] Preferably, the adjustment component includes an installation groove opened in the three-stage screening plate, each of the installation grooves is installed with a transversely arranged assembly plate, the assembly plate is provided with an assembly groove, the rod passes through the assembly groove and is slidably connected in the installation groove, an arc sleeve is rotatably connected to the rod, a straight spring is fixedly connected between the arc sleeve and the side wall of the assembly groove, a rotating column is also rotatably connected in the assembly groove, and a limiting cam that resists the rod is fixedly connected to the rotating column.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the interaction of structures such as strip grooves, rotating plates, and intercepting pins, the sides of the diverter plate can play a guiding role, so that the construction waste can enter the next process more stably. When the rotating plate encounters a waste gas bag during rotation, it can be hooked by the intercepting pin, and the setting of the barb prevents the hooked waste gas bag from falling off. At the same time, the sharp needle on the barb can further pierce the waste gas bag and fix it on the barb. Through the first-level screening component, a large number of waste gas bags in the construction waste can be screened out for harmless treatment.

[0019] 2. Through the interaction of structures such as the guard plate, rotating disk, cross pin, and mounting sleeve, as the rotating blades rotate and continuously stir the construction waste, the magnetic waste mixed in the waste can be adsorbed on the magnet. The multiple rotating blades are located at planes of different heights and are staggered. Such a setting can make the magnets on the rotating blades easier to adsorb and the screening of magnetic waste is more efficient.

[0020] 3. When the limit column rotates, it drives the lower mounting plate to rotate. The erroneous movement between the protrusions and the concave protrusions will drive the upper mounting disc to vibrate up and down, causing the construction waste inside the enclosure to roll continuously, thereby increasing the accuracy and efficiency of screening and saving time costs.

[0021] 4. By rotating the rotating column, the cam slowly squeezes the rod, allowing the rod to slowly move to the right. At this time, the straight spring slowly contracts and stops rotating at the appropriate distance. The rotating column remains stable under the action of friction and will not reset, thereby changing the distance between the rods and facilitating screening.

[0022] Through the screening of the above three processes, waste gas bags and ironware can be screened out, which is convenient for subsequent work. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Reference Figure 1-5 , a screening mechanism of an environmentally friendly mobile construction waste land restoration machine, comprising two mounting side plates 1, and also comprising:

[0034] The first-level screening component includes a first-level screening plate 2 installed on the upper end of the mounting side plate 1 and used for screening waste gas bags. A diverter plate 3 arranged in a triangular shape is installed on the first-level screening plate 2. When construction waste is poured in, the sides on both sides of the diverter plate 3 can play a guiding role, so that the construction waste can enter the next process more stably.

[0035] The primary screening component also includes strip grooves 17 symmetrically and laterally opened on the primary screening plate 2, and a rotatable rotating piece 5 is installed in each strip groove 17. A plurality of intercepting pins 18 arranged in an L shape are installed on both sides of the rotating piece 5, and each intercepting pin 18 is provided with a barb facing inward for rotating with the rotating piece 5, and each barb is provided with a plurality of sharp needles used therewith. The device is started to rotate the rotating piece 5, and the two rotating pieces 5 rotate inward in opposite directions. This can drive the construction waste into the next procedure on the one hand. When the rotating piece 5 rotates, it encounters a waste gas bag, which can be hooked by the intercepting pin 18, and the setting of the barb prevents the hooked waste gas bag from falling off. At the same time, the sharp needles on the barb can further pierce the waste gas bag and fix it on the barb. A large number of waste gas bags in the construction waste can be screened out for harmless treatment through the primary screening component.

[0036] The secondary screening component includes a secondary screening plate 7 installed between two mounting side plates 1 and located below the primary screening component. The secondary screening component also includes a protective plate 11 fixedly connected to the primary screening plate 2 and opening downward. The primary screening plate 2 is also provided with a second connecting plate 10 arranged in an inclined manner and a first connecting plate 4 arranged in a triangular prism, which play a role in guiding construction waste so that the construction waste can stably enter the protective plate 11.

[0037] A rotating disk 8 for providing centrifugal force is rotatably connected inside the enclosure plate 11. A rotating shaft arranged perpendicular to the enclosure plate 11 is installed at the center of the rotating disk 8. A cross pin 20 formed in one piece is installed at the top of the rotating shaft. A detachable and matching mounting sleeve 21 is clamped on the cross pin 20. The outer side of the mounting sleeve 21 is threadedly connected with multiple rotating blades 12. Two magnets 19 are symmetrically installed in each rotating blade 12. When construction waste enters the enclosure plate 11, the rotation of the rotating disk 8 will cause the construction waste to generate centrifugal force. When the construction waste rotates to the opening of the enclosure plate 11, the construction waste enters the next process under the action of centrifugal force. As the rotating blades 12 rotate and continuously stir the construction waste, the magnetic waste mixed in the waste can be adsorbed on the magnets 19. The multiple rotating blades 12 are located on planes at different heights and are staggered. Such an arrangement can make the magnets 19 on the rotating blades 12 easier to adsorb and the screening of magnetic waste is more efficient.

[0038] One end of the secondary screening plate 7 is rotatably connected to the mounting side plate 1, and the other end of the secondary screening plate 7 is connected to the mounting side plate 1 through a vibration assembly. The vibration assembly includes a limit column 9 connected at the corner of the primary screening plate 2 and for the primary screening plate 2 to slide up and down. The limit column 9 is provided with an upper mounting disc 6 embedded in the lower plane of the primary screening plate 2 and a lower mounting disc 15 fixedly connected to the limit column 9. The opposite surfaces of the lower mounting disc 15 and the limit column 9 are provided with recesses 16 and protrusions that match each other and can allow the upper mounting disc 6 to move up and down. When the limit column 9 rotates, it drives the lower mounting disc 15 to rotate. The erroneous movement between the protrusion and the recess 16 will drive the upper mounting disc 6 to vibrate up and down, thereby causing the construction waste inside the enclosure plate 11 to roll continuously, thereby increasing the accuracy and efficiency of screening and saving time costs.

[0039] The three-stage screening component includes a three-stage screening plate 13 installed between two mounting side plates 1. The three-stage screening device also includes a plurality of adjustment components installed in the three-stage screening plate 13. The three-stage screening plate 13 is installed with rods 14 through the adjustment components. The adjustment components are used to adjust the distance between the rods 14 so as to perform effective screening.

[0040] The adjusting component includes an installation groove 24 opened in the three-level screening plate 13, each installation groove 24 is installed with a transversely arranged assembly plate, the assembly plate is provided with an assembly groove, the rod 14 passes through the assembly groove and is slidably connected in the installation groove 24, the rod 14 is rotatably connected with an arc sleeve 26, a straight spring 22 is fixedly connected between the arc sleeve 26 and the side wall of the assembly groove, and a rotating column 25 is also rotatably connected in the assembly groove, and a limiting cam 23 that abuts against the rod 14 is fixedly connected to the rotating column 25, and a handle is provided on 25. When it is necessary to adjust the distance between the rods 14, the rotating column 25 can be rotated to allow the cam 23 to slowly squeeze the rod 14, so that the rod 14 slowly moves to the right, and at this time the straight spring 22 slowly contracts and stops rotating at a suitable distance, and the rotating column 25 remains stable under the action of friction and will not reset, thereby changing the distance between the rods 14, and thus facilitating screening.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
