Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0040] The embodiment of the present invention provides an air inner circulation dustproof bag breaking drum primary screening device, comprising a base 1. For example, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a support seat 2 is provided above the base 1; a sealing cylinder 3 is provided on the top of the support seat 2; a protective cover 4 is provided between the support seat 2 and the base 1; a feeding mechanism 5 is provided at one end of the sealing cylinder 3, and a discharging mechanism 6 is provided at the other end; a first collecting box 7 is provided at one end of the base 1 close to the feeding mechanism 5, and a second collecting box 8 is provided at the other end; a discharging hose 9 is provided on the top of the second collecting box 8; a first clamping ring 10 is provided at the end of the discharging hose 9 away from the second collecting box 8; a screening mechanism 11 is provided in the sealing cylinder 3; an adaptive flapping mechanism 12 is provided in the screening mechanism 11; a first circulation channel 13 is provided on the sealing cylinder 3; the first circulation channel 13 is connected with the feeding mechanism 5; a first discharging port 14 is provided on a side wall of the base 1 close to the feeding mechanism 5; the first discharging port 14 is connected with the first collecting box 7; a plurality of groups of receiving Box 15; the bottom of each group of the storage boxes 15 is an open structure; the top of each group of the storage boxes 15 is provided with a group of double-piston rod hydraulic cylinders 16; one of the output ends of each group of the double-piston rod hydraulic cylinders 16 is hinged to the sealing cylinder 3; the other output end of each group of the double-piston rod hydraulic cylinders 16 extends into the storage box 15, and is connected to a group of walking wheels 17 in transmission; a screening groove 21 is provided at the bottom of the sealing cylinder 3; a plurality of groups of scrapers 22 are evenly spaced at the top of the screening groove 21; each group of the scrapers 22 is movably in contact with the outer wall of the screening mechanism 11; the bottom of the screening groove 21 is connected with a centralizing cover 18; a conveyor belt 19 is provided in the base 1; the bottom of the centralizing cover 18 is movably fitted on the top of the conveyor belt 19; a circulating air pump 20 is provided on the bottom inner wall of the base 1; the input end of the circulating air pump 20 is connected with the centralizing cover 18, and the output end is connected with the first circulation channel 13.

[0041] When the primary screening device is working, the feed mechanism 5 is controlled to open the feed channel, and the circulating air pump 20 is started at the same time. The circulating air pump 20 extracts the air in the concentrated cover 18 and sprays the airflow through the feed mechanism 5 to generate an air wall, thereby preventing the dust generated by the decoration garbage during the screening process from escaping to the outside of the primary screening device. At the same time, the feed mechanism 5 can change the direction of the airflow to guide the airflow into the screening mechanism 11, thereby realizing the internal circulation of the air of the primary screening device, avoiding dust from polluting the air in the working area, which not only improves the environmental protection, but also improves the safety of the use of the primary screening device. Before the primary screening device is used, the output ends at the bottom of several groups of double piston rod hydraulic cylinders 16 are controlled to drive several groups of walking wheels 17 to extend from the storage box 15 and contact the ground, and the primary screening device is lifted. At this time, the primary screening device can be moved at will. At the same time, the output ends at the tops of several groups of double piston rod hydraulic cylinders 16 can be controlled to adjust the inclination angle of the sealing cylinder 3, so that different inclination angles can be used when screening different garbage, which not only improves the convenience of the primary screening device, but also improves the compatibility of the primary screening device.

[0042] For example, Figure 6 , Figure 7 and Figure 8 As shown, the feeding mechanism 5 includes a connecting ring 501; a fixing ring 505 is sleeved at one end of the connecting ring 501 close to the sealing cylinder 3; a second sealing plate 506 is arranged inside the fixing ring 505; a second circulation channel 507 is arranged on a side wall of the fixing ring 505 close to the sealing cylinder 3; the second circulation channel 507 is movably connected with the first circulation channel 13; a first air cavity 508 is arranged inside the connecting ring 501; the first air cavity 508 is connected with the second circulation channel 507; a rotating ring 502 is movably sleeved at one end of the connecting ring 501 away from the sealing cylinder 3; A first sealing plate 503 is provided in the rotating ring 502; the first sealing plate 503 and the second sealing plate 506 are movably fitted together on one side; an airflow guide plate 504 is provided in the rotating ring 502; the airflow guide plate 504 is located on the side of the first sealing plate 503 away from the second sealing plate 506; a plurality of groups of jet holes 510 are evenly spaced on a side wall of the first sealing plate 503 away from the inner wall of the rotating ring 502; a second air cavity 509 is provided in the rotating ring 502; the second air cavity 509 is connected to the first air cavity 508 and the plurality of jet holes 510.

[0043] When the primary screening device is working, the control rotating ring 502 drives the first sealing plate 503 to rotate upward, so that the feeding channel of the feeding mechanism 5 is exposed, and when the feeding work is performed, the output airflow of the circulating air pump 20 passes through the first circulation channel 13, the second circulation channel 507, the first air cavity 508 and the second air cavity 509 in turn, and then is ejected from a plurality of groups of jet holes 510 to form an air wall. The side wall of the airflow guide plate 504 close to the first sealing plate 503 is an arc surface, which can redirect the airflow into the sealing cylinder 3, and in the process of the airflow entering the sealing cylinder 3, the bottom of the fixing ring 505 will be cleaned to avoid dust accumulation. When the primary screening device is idle, the first sealing plate 503 can be controlled to rotate downward to close the primary screening device to prevent the internal structure from being exposed to external air for a long time, thereby improving the cleaning efficiency of the primary screening device and also improving the service life of the primary screening device.

[0044] For example, Fig. 9 As shown, the discharge mechanism 6 includes a sealing cover 601, and a second discharge port 602 is opened on the bottom inner wall of the sealing cover 601; a discharge pipe 603 is provided at the bottom of the sealing cover 601; a second clamping ring 604 is provided at the bottom of the discharge pipe 603; and the second clamping ring 604 is clamped with the first clamping ring 10.

[0045] When the primary screening equipment is working, bamboo, wood, fabric, plastic and other garbage are removed from the mixed particles through the screening mechanism 11, and then enter the sealing cover 601, and enter the second collecting box 8 for collection after passing through the second discharge port 602, the discharge pipe 603 and the discharge hose 9. The second collecting box 8 is connected to the discharge mechanism 6 through the soft discharge hose 9, which will not affect the angle adjustment of the sealing cylinder 3.

[0046] For example, Fig.10 As shown, the screening mechanism 11 includes a screening drum 1101; a plurality of groups of sieve holes 1102 are evenly distributed on the outer wall of the screening drum 1101; a plurality of groups of four-sided bag breaking knives 1103 are evenly distributed on the inner wall of the screening drum 1101; the cross section of the four-sided bag breaking knife 1103 is cross-shaped.

[0047] For example, Fig.11As shown, the adaptive flapping mechanism 12 includes two groups of support rods 1201; the two groups of support rods 1201 are symmetrically arranged at the two ends of the sealing cylinder 3; a mounting column 1202 is arranged between the two groups of sealing cylinders 3; a plurality of groups of electric telescopic rods 1203 are evenly spaced on the outer wall of the mounting column 1202; a group of flapping plates 1204 are transmission-connected to the output end of each group of electric telescopic rods 1203; a plurality of groups of bag breaking cones 1205 are distributed in a rectangular array on the side wall of each group of flapping plates 1204 away from the mounting column 1202; a straight pressure sensor 1206 is provided at the connection between the output end of each group of electric telescopic rods 1203 and the corresponding group of flapping plates 1204.

[0048] When the primary screening equipment is working, garbage such as bamboo, wood, fabric, and plastic enter the screening drum 1101. The particles attached to the garbage are separated from the garbage during the rotation of the screening drum 1101, and enter the collecting cover 18 after passing through a number of sieve holes 1102 and fall on the conveyor belt 19. Since the collecting cover 18 is under negative pressure, the dust floating in the air will also be sucked into the collecting cover 18. During the rolling process of the screening drum 1101, the four-sided bag-breaking knife 1103 will cut the packaging bag of the garbage to disperse the garbage. The four-sided bag-breaking knife 1103 has four cross-shaped blades to prevent the garbage from hanging on the bag-breaking knife. At the same time, during the garbage screening process, several groups of electric telescopic rods 1203 will drive several groups of beating plates 1204 to beat the garbage back and forth, so that the particles attached to the garbage can be separated more thoroughly, and several groups of bag breaking cones 1205 arranged on the beating plates 1204 can create openings on the garbage packaging bags, thereby improving the efficiency of the bag breaking work. At the same time, a pressure sensor 1206 is provided at the connection between the electric telescopic rod 1203 and the beating plate 1204, which can automatically adapt to the beating work of garbage of different thicknesses by sensing pressure, thereby improving the use effect of the primary screening equipment.

[0049] By controlling the feeding mechanism 5 to open the feeding channel and starting the circulating air pump 20 at the same time, the circulating air pump 20 draws out the air in the collecting hood 18 and sprays the air flow through the feeding mechanism 5 to generate an air wall, thereby preventing the dust generated by the decoration waste during the screening process from escaping to the outside of the primary screening equipment. At the same time, the feeding mechanism 5 can change the direction of the air flow and guide the air flow into the screening mechanism 11, thereby realizing the internal circulation of the air in the primary screening equipment and avoiding dust from polluting the air in the working area, which not only improves the environmental protection, but also improves the safety of the use of the primary screening equipment.

[0050] The airflow is ejected through several groups of jet holes 510 to form an air wall, and the airflow guide plate 504 can redirect the airflow into the sealing cylinder 3. In the process of the airflow entering the sealing cylinder 3, the bottom of the fixing ring 505 will be cleaned to avoid dust accumulation. At the same time, when the primary screening device is idle, the first sealing plate 503 can be controlled to rotate downward to seal the primary screening device, preventing the internal structure from contacting the external air for a long time, thereby improving the cleaning efficiency of the primary screening device and the service life of the primary screening device.

[0051] By utilizing the rolling of the screening drum 1101, several groups of four-sided bag-breaking knives 1103 are driven to cut open the garbage packaging bags to disperse the garbage. Several groups of electric telescopic rods 1203 will drive several groups of beating plates 1204 to beat the garbage back and forth, so that the particles attached to the garbage can be separated more thoroughly. Several groups of bag-breaking cones 1205 arranged on the beating plates 1204 can create openings on the garbage packaging bags, thereby improving the efficiency of the bag-breaking work. At the same time, a pressure sensor 1206 is provided at the connection between the electric telescopic rod 1203 and the beating plate 1204, which can automatically adapt to the beating work of garbage of different thicknesses by sensing pressure, thereby improving the use effect of the primary screening equipment.

[0052] By controlling the output ends of the bottom of several groups of double-piston-rod hydraulic cylinders 16, several groups of walking wheels 17 are driven to extend out of the storage box 15 and touch the ground, and the primary screening equipment is lifted. At this time, the primary screening equipment can be moved at will. At the same time, by controlling the output ends of the tops of several groups of double-piston-rod hydraulic cylinders 16, the inclination angle of the sealing cylinder 3 can be adjusted, so that different inclination angles can be used when screening different garbage, which not only improves the convenience of use of the primary screening equipment, but also improves the compatibility of use of the primary screening equipment.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
