Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a sand and gravel separator for construction engineering. Background Technique
[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation, and capable of forming an internal space to meet the needs of people's production, residence, study, and public activities. During construction, a large amount of sand and gravel waste is often generated. To avoid waste of resources, sand and gravel are often separated.
[0003] After retrieval, as disclosed in a Chinese patent document, a new type of sand and gravel separator [Publication No.: CN220406331U]. This new type of sand and gravel separator includes a base and a vibrating screen arranged on the base. A feeding hopper is slidably arranged above the vibrating screen. A hopper moving mechanism is arranged on the base. The hopper moving mechanism includes a sliding frame. The sliding frame includes an upper mounting plate, a left side plate and a right side plate arranged below both sides of the upper mounting plate. A sliding block is arranged at the bottom of the left side plate. A jack is opened on the side wall of the sliding block. A plurality of bearing seats are arranged on the base. A lead screw is rotatably arranged between adjacent bearing seats. One end of the lead screw passes through one of the bearing seats and is connected to a driving motor. A flange nut inserted and matched with the jack is slidably arranged on the lead screw.
[0004] The sand and gravel separator disclosed in this patent makes the sand and gravel waste evenly spread on the screen by setting a hopper moving mechanism that can drive the feeding hopper to slide along the length direction of the vibrating screen, which is beneficial to improving the screening efficiency of sand and gravel. Although the waste can be evenly spread on the screen, there are still deficiencies in actual use. When driving the feeding hopper to move, it is necessary to stop transporting sand and gravel in the feeding hopper to evenly spread the waste on the screen. After the sand and gravel in the feeding hopper is discharged, it needs to be poured again. This not only makes the operation more troublesome but also reduces the subsequent efficiency.

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 As shown, a sand and stone separator for construction engineering includes a base 1. Above the base 1, a screening box 2 is provided. Between the front and rear sides of the bottom of the screening box 2 and the top of the base 1, first springs 3 are fixedly arranged. At the bottom of the screening box 2, a vibration motor 4 is provided. Inside the screening box 2, a screening mesh 5 is movably connected. On the back of the screening box 2, a limiting structure 6 for limiting the screening mesh 5 is provided. At the top of the screening box 2, a feeding hopper 7 is fixedly arranged through a fixing frame. Inside the right side of the screening box 2, a pusher plate 8 is movably connected. Inside one end of the pusher plate 8, a movable plate 9 is movably connected. Between the movable plate 9 and the inner wall of one end of the pusher plate 8, a plurality of second springs 10 are fixedly arranged. On both sides between the inner side of one end of the pusher plate 8 and the inner wall of the screening box 2, third springs 11 are fixedly arranged. At the bottom of the pusher plate 8, a plurality of gear teeth 12 are fixedly arranged. On the right side of the screening box 2, a motor 13 is fixedly arranged. The output shaft of the motor 13 is bolted with an arc gear 14. The top of the arc gear 14 is meshed with the pusher plate 8 through the gear teeth 12.
[0024] The limiting structure 6 includes a screw rod 61, a crank 62, a fixing plate 63 and a limiting plate 64. The surface of the screw rod 61 is threadedly connected to the inner part of the back surface of the screening box 2. One end of the screw rod 61 is fixed to one side of the crank 62, and the other end of the screw rod 61 is rotatably connected to the bottom of the fixing plate 63. One side of the fixing plate 63 is fixed to one side of the limiting plate 64. In this way, when limiting the screening mesh 5, the crank 62 can be rotated to drive the screw rod 61 to rotate, and at the same time drive the fixing plate 63 and the limiting plate 64 to move upward, so as to limit the back surface of the screening mesh 5, facilitating the subsequent disassembly, installation and cleaning of the screening mesh 5.
[0025] Moving grooves 18 are formed on both sides of the back surface of the screening box 2, and the back surface of the limiting plate 64 is slidably connected to the inside of the moving groove 18. In this way, the limiting plate 64 can be assisted in limiting, facilitating its up and down movement.
[0026] A scraper 16 is fixedly connected to the top of the screening box 2, and the bottom of the scraper 16 is in contact with the top surface of the pushing plate 8. In this way, as the pushing plate 8 moves to the right, the scraper 16 will come into contact with the top of the pushing plate 8, so as to scrape and clean the top surface of the pushing plate 8.
[0027] Sliders 15 are fixedly connected to the front and rear sides of the bottom of the pushing plate 8, and the surfaces of the sliders 15 are movably connected to the inside of the right end of the screening box 2. In this way, the pushing plate 8 can be assisted in supporting and maintaining its stability during movement.
[0028] Discharge plates 17 are communicated with both the left side of the screening box 2 and the surface of the screening box 2, and the discharge plates 17 are inclined. In this way, the screened sand and waste can be guided to facilitate better subsequent blanking and collection.
[0029] It should be noted that in this technical solution, technical features such as... should be regarded as the prior art. For the specific structures, working principles, possible control methods and spatial arrangement methods of these technical features, conventional selections in this field can be adopted, and this technical solution will not be further specifically elaborated.
[0030] Working principle: When in use, the vibration motor 4 can be started, so that the screening box 2 vibrates through the elastic force of the first spring 3, and then the sand and gravel can be poured into the inside of the feed hopper 7, and the sand and gravel will fall down to the surface of the screening net 5 for screening, and the screened sand and gravel will be discharged to the left, and the screened waste will fall down and be discharged from the front, and as the sand and gravel are discharged from the bottom of the feed hopper 7, they will accumulate in one part of the screening net 5. At this time, the motor 13 can be started, and the arc gear 14 can be driven to rotate, and then the push plate 8 can be driven to move to the left. When moving, the sand and gravel accumulated in one place can be pushed by the push plate 8 and the movable plate 9. When the teeth on the surface of the arc gear 14 are separated from the surface of the gear teeth 12, the push plate 8 will be driven back to the starting position by the elastic force of the third spring 11 itself. Then, the sand and gravel inside the hopper 7 will continue to fall downward, and this process will be repeated, thereby improving the efficiency of subsequent screening. After the screening is completed, in order to facilitate the next use, the limit structure 6 can be used to cancel the limit on the screening net 5, and finally the screening net 5 can be pulled out, and the blockage on the surface of the limiting structure 6 can be cleaned.
