Description

Technical Field

[0001] This utility model relates to the field of sand and gravel screening technology, specifically an electric sand screening device for construction. Background Technology

[0002] In various construction projects, sand and gravel are widely used as basic building materials. In order to meet the specific requirements of sand and gravel particle size in different construction stages, such as masonry, plastering, and concrete mixing, it is usually necessary to screen the raw sand and gravel materials purchased or mined.

[0003] Traditional sand screening devices use manual screens to separate sand and gravel, and then transport the screened sand and gravel to the construction site using collection boxes. However, the collection of screened sand and gravel is inefficient, resulting in secondary dust and waste of fine sand and gravel during the material feeding and transportation process. In addition, the collection boxes are usually fixed or secured with simple pins when carrying the screened sand, which is cumbersome to operate, difficult to disassemble, and prone to shaking, displacement, or even falling off, leading to sand leakage, equipment damage, or safety accidents. Utility Model Content

[0034] For further reference Figure 2 , Figure 3 and Figure 4 The sand screening mechanism is located inside the sand screening box 3 and is used to screen sand and gravel used in construction. The sand screening mechanism includes a screening plate 6 and a screening plate 7 installed inside the sand screening box 3. Both screening plates 6 and 7 are inclined, and movable plates 10 are fixedly installed on both sides of the screening plates 6 and 7. The inner wall of the sand screening box 3 is provided with a vibration groove for the movable plates 10 to move. A vibration spring 9 is connected between the movable plates 10 and the vibration groove. A vibration motor 8 is fixedly installed at the bottom of both screening plates 6 and 7.

[0035] Furthermore, a guide plate 11 is fixedly installed on the top of the inside of the sand screening box 3. The guide plate 11 is inclined. The top of the guide plate 11 corresponds to the feed inlet 4, and the bottom of the guide plate 11 corresponds to the screening plate 6. Discharge ports are opened on both sides of the sand screening box 3. Both discharge ports are matched with the screening plate 6 and the screening plate 7. Collection boxes 5 corresponding to the discharge ports are fixedly installed on both sides of the sand screening box 3.

[0036] The overall working principle of this utility model is as follows:

[0037] The sand and gravel mixture to be screened is fed into the sand screening box 3 through the feed port 4 at the top of the sand screening box 3. The sand and gravel first fall onto the guide plate 11 fixedly installed at the top of the sand screening box 3. Since the guide plate 11 is inclined, the sand and gravel slide off its surface and are guided to the upper end of the screening plate 6 located in the upper layer inside the sand screening box 3. The vibration motor 8 installed at the bottom of the screening plate 6 is started. The vibration generated by the vibration motor 8 is transmitted to the screening plate 6. The screening plate 6 is installed at an inclination. The vibration spring 9 allows the screening plate 6 to make small reciprocating movements during vibration, while also playing a buffering role to reduce the transmission of vibration to the main body of the sand screening box 3. Under the action of vibration and inclination, the sand and gravel move downward on the screening plate 6. Sand particles smaller than the mesh of the screening plate 6 pass through the mesh and fall down, while large-diameter sand and gravel larger than the mesh moves along the inclined surface of the screening plate 6 and is finally discharged through the discharge port corresponding to the side wall of the sand screening box 3 and falls into the collection box 5.

[0038] Medium-sized sand and gravel passing through screening plate 16 fall onto screening plate 27, which is also installed at an angle below screening plate 16. The mesh of screening plate 27 is smaller than that of screening plate 16. It is also vibrated by vibration motor 8. Under the action of vibration and tilting, the finest sand and gravel smaller than the mesh of screening plate 27 passes through the mesh and falls down, while medium-sized sand and gravel move along the surface of screening plate 27 and are finally discharged through another discharge port corresponding to the side wall of screening box 3, falling into the collection box 5 on the other side. The finest sand and gravel passing through screening plate 27 falls into the receiving box 23 located directly below screening box 3.

[0039] When it is necessary to remove the sand and gravel collected inside the receiving box 23, the operator rotates the control knob 26 fixed on the top of the screw 210, causing the nut 28 to rotate. When the nut 28 rotates, it moves on the outer wall of the screw 210. The movement of the nut 28 drives the bearing 29 to move, and the movement of the bearing 29 drives the positioning plate 25 to move synchronously until the nut 28 is completely separated from the screw 210. Then, the electric push rod 21 drives the receiving plate 211 to move, and the receiving plate 211 moves. The movement of plate 11 causes the top receiving box 23 to move downward synchronously under the gravity of the sand and gravel. The movement of the receiving plate 211 drives the movement of multiple extension rods 213. Through the cooperation of the limiting rod 212 and the limiting sleeve 27, and the correspondence between the limiting hole and the limiting rod 212, the receiving plate 211 is more stable when it moves downward. When the receiving box 23 moves to a position that is convenient for the user to take out the sand and gravel inside, the electric push rod 21 can stop working, so as to facilitate the removal of the finest sand and gravel after screening.
