[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] like Figure 1-3 As shown, the embodiment of the utility model provides a sand and gravel screening system, comprising:
[0023] A vibrating screen 1, the vibrating screen 1 is connected to a supporting frame through a vibrating spring, a screening net is provided in the middle of the vibrating screen 1, the vibrating screen 1 has a hopper below the screening net, the hopper has a sand and gravel outlet 2, a horizontal cylinder 20 is fixed on the side of the vibrating screen 1, and a screening cylinder 11 is fixedly connected to the horizontal cylinder 20;
[0024] A first climbing conveyor line 3, wherein the first climbing conveyor line 3 is located below the sand and gravel outlet 2 of the vibrating screen;
[0025] A second climbing conveyor line 4, which is located on the side of the vibrating screen, is provided with a bracket 5 fixed thereon, a baffle 6 is fixed in the bracket 5, and an inclined plate 7 is also fixed on the bracket 5, the outlet of the screening drum corresponds to the inclined plate 7, and there is a gap between the inclined plate 7 and the baffle 6 and the conveyor belt of the second climbing conveyor line.
[0026] The process of the utility model when in use is as follows: first, the sand and gravel that need to be screened are injected into the vibrating screen 1, and the vibration motor 17 connected to the vibrating screen starts to vibrate. Since the vibrating screen is connected to the supporting frame through a vibration spring, the vibrating screen can achieve vibration, and the screening of the screening net of the vibrating screen 1 makes the fine sand and gravel fall into the hopper and be discharged from the sand and gravel outlet 2 of the hopper, and finally fall onto the first climbing conveyor line 3 and be transmitted upward through the first climbing conveyor line 3. At the same time, the sand and gravel with larger particles cannot be screened out from the screening net, and will move around due to the vibration, and finally fall into the horizontal cylinder 20, and fall out of the screening cylinder 11, and will fall onto the inclined plate 7, and finally slide from the inclined plate 7 to the conveyor belt of the second climbing conveyor line 4, and finally be transmitted upward through the second climbing conveyor line 4, so as to separate the fine sand and gravel in the sand and gravel.
[0027] Furthermore, the inclined plate 7 has an inclination angle of 60 degrees. Specifically, the inclined plate 7 of the utility model has an inclination angle of 60 degrees, and the inclined plate 7 can make the sand and gravel fall downward smoothly.
[0028] Furthermore, the bracket 5 includes a door frame 8, the baffle 6 is fixed on the door frame 8, a cross beam 9 is also fixed on the door frame 8, and the inclined plate 7 is fixed on the cross beam 9. The bracket 5 of the utility model is a door frame 8, which is fixed to both ends of the side beam of the second climbing conveyor line 4 through the door frame 8, and the baffle 6 is fixed to the door frame 8 by rivets. The cross beam 9 on the door frame 8 is used to fix the inclined plate 7, so as to guide the sand and gravel while preventing it from sliding downward.
[0029] Further, the conveyor belt of the second climbing conveyor line 4 is provided with anti-skid patterns 10. Specifically, the utility model is provided with anti-skid patterns 10 on the conveyor belt of the second climbing conveyor line 4, and the anti-skid patterns 10 can increase the friction of the sand and gravel to prevent it from sliding down.
[0030] Furthermore, the first climbing conveyor line 3 and the second climbing conveyor line 4 both adopt concave conveyor lines (the concave conveyor line is not shown). Specifically, the utility model adopts a concave conveyor line (a mature structure that can be directly purchased on the market), and a groove can be formed in the middle area of the conveyor belt, and fine sand and gravel can be deposited in the groove, which is convenient for upward transmission.
[0031] Further, the screening drum 11 includes a straight cylinder portion, a guide slide 13 is fixed below the straight cylinder portion, and the guide slide 13 includes a first side plate 12 and a second side plate 14, the first side plate 12 and the second side plate 14 are respectively fixed on both sides of the straight cylinder portion, and an inclined slide plate is fixed between the first side plate 12 and the second side plate 14. Specifically, there is a guide slide 13 below the screening drum 11, and the slide plate is in an inclined state, and its outlet faces the inclined plate 7, so that it can ensure that sand and gravel can fall directly onto the inclined plate 7.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
