Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a sand screening machine for building construction. Background Technology

[0002] Sand is an indispensable basic material in construction. However, natural sand or sand transported from sand pits often contains various impurities, such as stones and leaves. These impurities can affect the performance of sand in construction and require screening.

[0003] Chinese Patent CN215940551U discloses a sand screening machine for construction, relating to the field of construction. The sand screening machine includes: a protective shell with a sand outlet on its lower surface; and a screening mechanism connected to the protective shell. The screening mechanism includes a screening chamber and a rotating rod. The screening chamber is fixedly connected inside the protective shell, and two symmetrically arranged hydraulic telescopic cylinders are fixedly connected to the lower outer surface of the screening chamber. One end of each hydraulic telescopic cylinder is fixedly connected to the protective shell. The rotating rod is fixedly connected inside the screening chamber, and a first screening screen and a second screening screen are rotatably connected to the rotating rod. A drive motor for driving the rotating rod is fixedly connected to the lower outer surface of the screening chamber. However, in the aforementioned patent, sand needs to be injected into the screening chamber for screening. Since the screening chamber has limited storage capacity, frequent injection of sand is required, making rapid and continuous screening difficult and reducing the screening speed. Therefore, we propose a sand screening machine for construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sand screening machine for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sand screening machine for construction includes a hopper, a feeding component on the outside of the hopper, two sets of support plates fixedly connected to the outer surface of the hopper, two sand screening frames below the hopper, support components on the side of the two sets of support plates that are close to each other, bearing rings embedded on the side of the two sets of support plates that are close to each other, two rotating rods connected to the inner rings of the two sets of bearing rings, the outer surfaces of the two rotating rods respectively connected to the bottom surfaces of the two sand screening frames, a guide frame below the two sand screening frames, and two injection pipes connected to the bottom surface of the hopper.

[0007] In a further embodiment, the feeding component includes a geared motor mounted on the outer surface of the feeding hopper, a drive rod mounted on the output end of the geared motor, a bidirectional spiral feeding blade connected to the outer surface of the drive rod, and two bearing rings embedded in the inner wall of the feeding hopper, the inner rings of the two bearing rings being connected to the outer surface of the drive rod.

[0008] In a further embodiment, both sets of support members include a fixing plate mounted on one side of the support plate, and two sets of tension springs are connected to the bottom surface of both sets of fixing plates. Two connecting plates are connected to the outer surface of both sand screening frames. The bottom ends of the two sets of tension springs are respectively connected to the upper surface of the two sets of connecting plates, and a vibration motor is mounted on the bottom surface of both sets of connecting plates.

[0009] In a further embodiment, one side of each of the two sets of support plates is connected to the outer surface of the two guide frames, and the two sand screening frames are located above the two guide frames.

[0010] In a further embodiment, a support plate is fixedly connected to one side of the two support plates that are close to each other. A controller is fixedly installed on the front of the support plate, and an anti-slip base is fixedly connected to the bottom surface of both sets of support plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a hopper to store large quantities of sand. Simultaneously, a feeding mechanism drives a geared motor to rotate the drive rod and bidirectional spiral feed blades, enabling bidirectional pushing of the sand within the hopper. The sand then continuously slides through two feeding pipes onto two sand screening frames, eliminating the tedious manual filling process and ensuring continuous and stable sand screening. The vibration generated by the vibrating motor on the two screening frames ensures thorough screening of the sand within both frames. This achieves simultaneous bidirectional sand screening, significantly improving screening efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4In this utility model, a sand screening machine for construction includes a hopper 1, a feeding component 2 on the outside of the hopper 1, two sets of support plates 3 fixedly connected to the outer surface of the hopper 1, two sand screening frames 4 below the hopper 1, support components 5 on the side of the two sets of support plates 3 that are close to each other, and bearing rings 8 embedded on the side of the two sets of support plates 3 that are close to each other, and two rotating rods 7 connected to the inner rings of the two sets of bearing rings 8, respectively. The outer surfaces of the two rotating rods 7 are connected to the bottom surfaces of the two sand screening frames 4. Through the cooperation of the rotating rods 7 and the bearing rings 8, one end of the sand screening frame 4 is supported, and the sand screening frame 4 rotates slightly around the rotating rods 7, so that the other end of the sand screening frame 4 can vibrate up and down better when screening sand, and avoid the phenomenon of deviation. Guide frames 6 are provided below the two sand screening frames 4. Conveying equipment can be added below the two guide frames 6 as needed to transport the screened sand. Two injection pipes 9 are connected to the bottom surface of the hopper 1.

[0022] In a further embodiment, the feeding component 2 includes a geared motor 201 mounted on the outer surface of the feeding hopper 1. A drive rod 202 is mounted on the output end of the geared motor 201. A bidirectional spiral feeding blade 203 is connected to the outer surface of the drive rod 202. Two bearing rings 204 are embedded in the inner wall of the feeding hopper 1. The inner rings of the two bearing rings 204 are connected to the outer surface of the drive rod 202. The geared motor 201 drives the rotation of the drive rod 202 and the bidirectional spiral feeding blade 203. In addition, the special structure of the bidirectional spiral feeding blade 203 can continuously and stably convey the material to the top of the two sand screening frames 4, solving the problem of frequent manual feeding in traditional sand screening machines. The setting of the two bearing rings 204 can provide stable support and rotation conditions for the drive rod 202, reducing shaking and friction loss.

[0023] In a further embodiment, both sets of support members 5 include a fixing plate 501 mounted on one side of the support plate 3. The bottom surfaces of both sets of fixing plates 501 are connected to two sets of tension springs 502. The outer surfaces of both sand screening frames 4 are connected to two connecting plates 503. The bottom ends of the two sets of tension springs 502 are respectively connected to the upper surfaces of the two sets of connecting plates 503. The bottom surfaces of both sets of connecting plates 503 are equipped with vibration motors 504. Through the cooperation of the two sets of tension springs 502 and the connecting plates 503, an elastic support structure can be formed. When the vibration motor 504 is started, the tension springs 502 can buffer the impact force generated by the vibration of the sand screening frame 4, and prevent the sand screening machine from shifting or becoming loose due to excessive vibration amplitude. At the same time, it can keep the sand screening frame 4 at a reasonable vibration frequency and amplitude, ensuring that the sand is fully screened in the sand screening frame 4 and improving the screening effect.

[0024] In a further embodiment, the two sets of support plates 3 are connected to the outer surfaces of the two guide frames 6 on their adjacent sides. The two sand screening frames 4 are located above the two guide frames 6. The two sets of support plates 3 are fixedly connected to a support plate 10 on their adjacent sides. A controller 11 is fixedly installed on the front of the support plate 10. Anti-slip bases 12 are fixedly connected to the bottom surfaces of the two sets of support plates 3. By positioning the two sand screening frames 4 above the guide frames 6, bidirectional screening of sand is achieved, improving sand screening efficiency. The controller 11 can be used to adjust the operating parameters of various components of the sand screening machine, such as feeding speed and vibration frequency. The two sets of anti-slip bases 12 increase the friction between the sand screening machine and the ground, preventing the equipment from sliding due to vibration or external force during operation.

[0025] The working principle of this utility model is as follows: First, a large amount of sand is injected into the inside of the hopper 1. Then, the feeding device 2 is started to push the sand in the hopper 1 in both directions. The sand in the hopper 1 will flow into the top of the two sand screening frames 4 through the two feeding pipes 9. Then, the vibration motor 504 is started, which can drive the sand screening frame 4 to vibrate up and down. Under the action of vibration, the sand in the sand screening frame 4 is fully screened. Sand of different particle sizes is separated by the screen. Then, the screened sand falls into the corresponding guide frame 6 below for discharge.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
