Description

Technical Field

[0001] The utility model particularly relates to a high-efficiency sand and gravel vibrating screen. Background Art

[0002] With the rapid development of the economy, the development of the construction industry has also kept pace. Among them, sand and gravel are indispensable raw materials in construction projects. However, the sizes of common sand and gravel on the market are of various sizes, there is no clear division of specifications, and the uses are also numerous. Usually, a construction site needs to use sand and gravel of various specifications. In order to meet market demand, sand making plants will screen and classify the sand and gravel processed by sand making machines.

[0003] After the current sand and gravel vibrating screen finishes screening the sand and gravel, the screened sand and gravel will fall directly into the collection box on the ground. Subsequently, the sand and gravel in the collection box need to be manually transported, which increases labor costs and reduces work efficiency. Utility Model Content

[0006] Preferably, the screening assembly includes a rotating shaft arranged on the first supporting frame, support rods are arranged at equal intervals around the outer side of the rotating shaft, and a screening cylinder is arranged on the outer side of the support rods.

[0007] Preferably, the feed port of the screening drum is communicated with the discharge port of the feeding funnel.

[0008] Preferably, a support plate is provided on the first support frame and at the end of the screening drum, a motor is provided on the support plate, and a power output end of the motor is connected to the rotating shaft.

[0009] Preferably, the material transfer assembly includes transmission shafts arranged at the head and tail of the second support frame, and a conveyor belt is arranged between the two transmission shafts.

[0010] Preferably, a blanking assembly is provided at the transmission end of the transmission belt, and the blanking assembly includes two rotating rods, two springs and a blanking plate provided on the second supporting frame.

[0011] Preferably, the two rotating rods are respectively arranged on both sides of the transmission end, the springs are respectively arranged on the outside of the rotating rods, and the blanking plate is installed between the two rotating rods.

[0012] The technical effects and advantages of the utility model are as follows: the high-efficiency sand and gravel vibrating screen pours the sand and gravel to be screened into the feeding funnel, and as the power output end of the motor drives the rotating shaft to rotate, the screen drum is driven to rotate through the connection of the support rod to screen the sand and gravel, and the screened sand and gravel directly passes through the surface of the screen drum and falls to the surface of the conveyor belt. As the drive shaft rotates, the conveyor belt is driven to transmit the screened sand and gravel to a high place. When the sand and gravel fall from the transmission end of the conveyor belt, it will first fall onto the discharge plate. As the rotating rod rotates, the discharge plate rotates to avoid the sand and gravel from falling directly over a large range. The screened sand and gravel can be directly transported to a high place without the need for manual handling at a later stage, which saves labor costs and improves work efficiency.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] In order to facilitate the adjustment of the transmission direction of sand and gravel after screening, refer to Figure 1 、 Figure 2 and Figure 3As shown, it includes a first supporting frame 1 arranged vertically and a second supporting frame 2 arranged obliquely. A feeding funnel 3 and a screening assembly are provided on the first supporting frame 1. The screening assembly is arranged at the discharge port 4 of the feeding funnel 3. A material transfer assembly is provided on the second supporting frame 2. The material transfer assembly is used to transport the sand and gravel screened by the screening assembly toward a higher place, and pour the sand and gravel to be screened into the feeding funnel 3. As the power output end of the motor 9 drives the rotating shaft 5 to rotate, the screening drum is driven by the connection of the support rod 6. 7 rotates to screen the sand and gravel. The screened sand and gravel directly pass through the surface of the screening drum 7 and fall onto the surface of the conveyor belt 11. As the transmission shaft 10 rotates, the conveyor belt 11 is driven to transmit the screened sand and gravel to a higher place. When the sand and gravel fall from the transmission end of the conveyor belt 11, they will first fall onto the discharge plate 14. As the rotating rod 12 rotates, the discharge plate 14 rotates to avoid the sand and gravel falling directly over a large range. The screened sand and gravel can be directly transported to a higher place without the need for manual handling at a later time, thus saving labor costs.

[0020] In order to control the range of sand and gravel falling, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the screening assembly includes a rotating shaft 5 provided on a first support frame 1, support rods 6 are provided at equal intervals around the outside of the rotating shaft 5, and a screening drum 7 is provided on the outside of the support rods 6. The rotation of the rotating shaft 5 drives the support rods 6 to rotate, so that the screening drum 7 rotates accordingly, and the sand and gravel after screening can fall directly onto the conveyor belt 11. The feed port of the screening drum 7 is connected to the discharge port 4 of the feed funnel 3, and the sand and gravel that need to be screened can directly enter the screening drum 7 for screening. A support plate 8 is provided on the first support frame 1 and at the end of the screening drum 7. A motor 9 is provided on the support plate 8. The power output end of the motor 9 is connected to the rotating shaft 5, and the stability of the motor 9 is improved by the support plate 8. The rotating shaft 5 is driven to rotate by the motor 9, thereby driving the rotation of the screening drum 7. The material transfer assembly includes drive shafts 10 mounted at the head and tail of the second support frame 2. A conveyor belt 11 is installed between the two drive shafts 10. A power unit, such as a motor 9, is installed outside the drive shafts 10. This is conventional technology and will not be described in detail here. The screened sand and gravel are transported via the conveyor belt 11. A discharge assembly is located at the end of the drive belt. This discharge assembly comprises two rotating rods 12, two springs 13, and a discharge plate 14, mounted on the second support frame 2. The two rotating rods 12 are located on either side of the discharge end, with the springs 13 located outside each of the rotating rods 12. The discharge plate 14 is mounted between the two rotating rods 12. As sand and gravel fall from the discharge end, they land on the discharge plate 14. As the amount of sand and gravel increases and its weight increases, the rotating rods 12 rotate, driving the discharge plate 14 to rotate, allowing the sand and gravel to fall, thus controlling the range of its fall. After the sand and gravel fall, the springs 13 resiliently return the discharge plate 14 to its original position.

[0021] During use, the sand and gravel to be screened are poured into the feed funnel 3. As the power output end of the motor 9 drives the rotating shaft 5 to rotate, the screening drum 7 is driven to rotate through the connection of the support rod 6 to screen the sand and gravel. The screened sand and gravel directly pass through the surface of the screening drum 7 and fall onto the surface of the conveyor belt 11. As the transmission shaft 10 rotates, the conveyor belt 11 is driven to transmit the screened sand and gravel to a high place. When the sand and gravel fall from the transmission end of the conveyor belt 11, it will first fall on the discharge plate 14. As the rotating rod 12 rotates, the discharge plate 14 rotates. After the sand and gravel fall, the discharge plate 14 returns to its initial state under the elastic action of the spring 13.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
