[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0025] Example: Figures 1-5 As shown, this embodiment proposes a green and environmentally friendly sand screening equipment for construction, including a sand screening equipment frame 1, an anti-blocking mechanism 3 for preventing blockage during screening, and a feeding mechanism 4 for conveying the screened sand.
[0026] like Figure 1 , Figure 3 and Figure 4As shown, the anti-blocking mechanism 3 includes two support columns 33 rotatably connected to one side of the outside of the sand screening device frame 1, which can provide lateral support force and rotation ability. The two support columns 33 are fixedly connected with a support rod 34 on the outside, which can provide ability and can be driven to rotate by the rotation of the support column 33. The bottom of the support rod 34 is fixedly connected with a connecting block 36, which can provide connection ability and support ability, and the connecting block 36 is designed to be inclined and connected to the bottom of the support rod 34. The outside of the connecting block 36 is fixedly connected with a force block 37, which can provide support ability and pressure receiving ability. The top of the support rod 34 is fixedly connected with a knocking block 35, which can provide knocking ability. When the support column 33 drives the support rod 34 to rotate, it can drive the knocking block 35 to rotate. The top side of the sand screening device frame 1 is provided with a driving assembly 38 for driving the sand screening device frame 1 to screen. The outside of the driving assembly 38 is rotatably connected with a main shaft 39, which can provide support ability and rotation ability. The outside of the main shaft 39 is fixedly connected with a cylindrical screening net 31, which can provide filtering ability. The outside of the cylindrical screening net 31 is fixedly connected with two right-angle blocks 32, which can provide docking ability. In use, when the main shaft 39 drives the cylindrical screening net 31 to rotate, it drives the right-angle block 32 to rotate. When rotating, the right-angle block 32 contacts the force block 37, causing the support rod 34 to rotate. When the support rod 34 rotates, it can drive the knocking block 35 to incline to one side of the cylindrical screening net 31, knocking the outside of the cylindrical screening net 31, which can prevent the holes of the cylindrical screening net 31 from being blocked, reducing its working efficiency.
[0027] As shown in Figure 4 , the driving assembly 38 includes a support block 381 fixedly connected to one side of the top of the sand screening device frame 1, which can provide support ability and enable the main shaft 39 to rotate inside the support block 381. The outside of the main shaft 39 is rotatably connected to the top of the support block 381. The outside of the main shaft 39, i.e. the side close to the support block 381, is fixedly connected with a motor 382, which can provide driving ability to convert electrical energy into driving ability, so that the output end can rotate. The output end of the motor 382 is fixedly connected to the outside of the main shaft 39, so that the motor 382 can drive the main shaft 39 to rotate.
[0028] As shown in Figure 3 and Figure 4 , the outside of the right-angle block 32 and the force block 37 is a right-angled triangle, and the inclined surfaces are opposite to each other, which can provide extrusion ability and facilitate the rotation of the support column 33 to make the force block 37 away from one side of the cylindrical screening net 31.
[0029] As shown in Figure 1 ,Figure 2 And Figure 5 As shown in the figure, the inside of the sand screening equipment frame 1 is provided with a conveying belt 2, which is designed by a belt, rotating rollers, etc. Here is the prior art, so it is not necessary to elaborate too much, so that the column screening net 31 will drop the filtered sand to the surface of the conveying belt 2 through free fall, and then be conveyed out. The bottom of the sand screening equipment frame 1 is fixedly connected with a drainage plate 5, which is designed to guide and convey the larger particles rotated by the column screening net 31.
[0030] As shown in the figure Figure 2 And Figure 5 As shown in the figure, the feeding mechanism 4 includes a feeding pipe 45 fixedly connected to the top of the sand screening equipment frame 1, which is designed to provide a conveying channel for screening. The outside of the feeding pipe 45, i.e. the side close to the column screening net 31, is fixedly connected with a support plate 41, which is designed to provide good support ability and at the same time provide good support ability for the other end of the main shaft 39.
[0031] As shown in the figure Figure 2 The outside of the main shaft 39 is rotatably connected to the outside of the support plate 41. The outside of the support plate 41, i.e. the side away from the column screening net 31, is fixedly connected with a connecting rod 42, which is designed to provide connection ability so that the rotation of the main shaft 39 can cause the connecting rod 42 to rotate.
[0032] As shown in the figure Figure 2 As shown in the figure, the outside of the connecting rod 42 is fixedly connected with a stirring rod 43, which is designed to provide stirring ability. When the sand to be screened enters the inside of the feeding pipe 45, the rotation of the main shaft 39 can drive the connecting rod 42 to rotate, and then the rotation of the stirring rod 43 can stir the sand in the inside of the feeding pipe 45 to prevent clogging. The inside of the sand screening equipment frame 1, i.e. the side close to the feeding pipe 45, is fixedly connected with a guide plate 44. After the sand is stirred by the stirring rod 43, it will fall into the inside of the guide plate 44, and then flow into the inside of the column screening net 31 for screening.
[0033] Working principle: the green building sand screening equipment provided by the utility model drives the motor 382 in the driving assembly 38 to work when screening, converts electric energy into rotational energy, and drives the main shaft 39 to rotate. The rotation of the main shaft 39 drives the column screening net 31 to rotate, and at the same time, the two right angle blocks 32 on the column screening net 31 also rotate. When the right angle block 32 rotates to contact the stress block 37, the inclined surface of the right angle block 32 and the inclined surface of the stress block 37 are pressed against each other (as shown in the figure Figure 1The outer part of the right-angle block 32 and the force-receiving block 37 is in the shape of a right-angled triangle, so that the force-receiving block 37 can effectively receive the force from the right-angle block 32. When the force-receiving block 37 is pressed, the force is transmitted to the supporting rod 34 through the connecting block 36, and the rotating ability of the supporting column 33 enables the supporting rod 34 to rotate. The rotation of the supporting rod 34 further drives the knocking block 35 to move. With the rotation of the supporting rod 34, the knocking block 35 tilts to one side of the cylindrical screening net 31 and knocks the outer part of the cylindrical screening net 31. Such knocking action can effectively prevent the holes of the cylindrical screening net 31 from being blocked (as shown in Figure 2 so as to ensure the smooth screening and avoid the reduction of working efficiency due to the blocking of the screening net. Then, the sand meeting the particle size requirement falls through the holes of the cylindrical screening net 31 and freely falls onto the conveying belt 2 inside the sand screening equipment frame 1, conveying the screened sand to the outside of the equipment and completing the conveying process. Meanwhile, the drainage plate 5 can drain and convey the larger particles, so as to effectively separate and convey the sand of different particle sizes (as shown in Figure 1 ;
[0034] When in use, the sand to be screened passes through the feeding pipe 45, which provides a channel for the conveying of the sand and ensures that the sand can smoothly enter the inside of the cylindrical screening net 31. Outside the feeding pipe 45, the supporting plate 41 provides good support for the entire feeding mechanism 4 and also provides stable support ability for the other end of the main shaft 39. The main shaft 39 starts to rotate under the driving of the motor 382 (as shown in Figure 2 The outer part of the main shaft 39 is rotationally connected with the supporting plate 41, so that the main shaft 39 can stably rotate. The rotation of the main shaft 39 is transmitted to the connecting rod 42 through the supporting plate 41, so that the connecting rod 42 also rotates. When the main shaft 39 drives the connecting rod 42 to rotate, the poking rod 43 also moves and can stir the sand entering the inside of the feeding pipe 45. Through such stirring, the sand can be effectively prevented from being blocked in the inside of the feeding pipe 45, so as to ensure that the sand can smoothly enter the screening link. The sand stirred by the poking rod 43 falls onto the guide-in plate 44 inside the sand screening equipment frame 1 (as shown in Figure 2 The design of the guide-in plate 44 enables the sand to smoothly flow to the inside of the cylindrical screening net 31 for screening.
[0035] All the technical features in the embodiment can be freely combined according to actual needs.
[0036] The above embodiment is a preferred implementation scheme of the present application, and the present application can also be implemented in other ways without departing from the technical concept of the present application. Any obvious replacement within the scope of the present application is within the protection scope of the present application.
