[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.
[0003] A search revealed a Chinese patent document disclosing a screening and mixing device for construction engineering [Announcement No.: CN112619472A]. This device includes a base and a mixing chamber. The base is equipped with a power chamber, a right slide chute, a middle slide chute, and a left base. The power chamber is fixed to the top right side of the base with screws. The right slide chute is fixed to the front right side of the base with screws. The middle slide chute is fixed to the front middle of the base with screws. The left base is fixed to the top left side of the base with screws. The mixing chamber is located on the left side of the base. This invention allows for easy independent operation of screening and mixing of building materials using a single motor, effectively saving energy.
[0004] To ensure the smoothness of the house walls, cement mortar will be applied to the walls. Cement mortar is formed by mixing a certain proportion of cement powder and sand with water and using a mixing device. Since cement mortar needs to be applied to the wall, it is necessary to ensure that there are no foreign objects in the sand. However, the existing mixing device has a poor screening effect and cannot quickly screen out foreign objects in the sand. To address this problem, we propose a screening and mixing device for construction engineering. Utility Model Content
[0005] The purpose of this invention is to provide a screening and mixing device for construction engineering to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a screening and mixing device for construction engineering, comprising a base and a mixing tank, wherein the mixing tank is fixedly installed on the top of the base, a support frame is fixedly connected to the top of the base, a screening frame is provided on the top of the mixing tank, one side of the screening frame is fixedly connected to the inner wall of the support frame, and a dispersing and mixing mechanism is provided on the top of the support frame. The dispersing and stirring mechanism includes a motor fixedly installed on the top of the support frame. The output end of the motor extends through to the bottom of the support frame and is fixedly connected to a linkage rod. The bottom of the linkage rod extends through the screening frame and into the interior of the mixing tank. Four stirring rods are fixedly connected to the circumferential side of the linkage rod. The screening frame is equipped with a dispersing plate inside, and a dispersing block is fixedly connected to the bottom of the dispersing plate. One side of the dispersing plate is fixedly connected to the surface of the linkage rod. A vibration mechanism is fixedly mounted on the screening frame.
[0007] Preferably, the vibration mechanism includes two vibration blocks fixedly connected to both sides of the screening frame. An extrusion rod is provided inside the screening frame. One end of the extrusion rod extends through to one side of the support frame and is fixedly connected to a linkage block. Two striking rods are fixedly connected to one side of the linkage block, and one end of the striking rod contacts one side of the vibration block. Two tension springs are fixedly connected to one side of the support frame, and one end of each tension spring is fixedly connected to one side of the linkage block.
[0008] Preferably, two guide rods are fixedly connected to one side of the support frame, and a guide hole is provided on one side of the linkage block to cooperate with the guide rods.
[0009] Preferably, a spring is fixedly connected to one side of the vibrating block, and a counterweight is fixedly connected to one end of the spring.
[0010] Preferably, both sides of the extrusion rod are sloped and are positioned opposite to the dispersing plate.
[0011] Preferably, the number of the dispersion blocks is several, and they are evenly distributed at the bottom of the dispersion plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a dispersing and stirring mechanism, this utility model can pour sand into the screening frame and start the motor at the same time. The motor will drive the linkage rod and stirring rod to rotate. The linkage rod will drive the dispersing plate to rotate, and the dispersing plate will also drive the dispersing block to rotate. During the rotation of the dispersing block, the sand will be evenly dispersed on the screening frame, avoiding sand accumulation and thus improving the screening speed. 2. By setting up a vibration mechanism, this utility model enables the dispersing plate to rotate. When the dispersing plate is squeezed out by the inclined part of the extrusion rod, the extrusion rod drives the linkage block and the striking rod to move away from the dispersing plate. At the same time, the linkage block will stretch the tension spring. When the dispersing plate rotates to the point where it is no longer in contact with the extrusion rod, the tension generated by the tension spring will drive the linkage block and the striking rod to suddenly return to their original positions. The striking rod will strike the vibrating block to generate vibration, and the vibration force will be transmitted to the screening frame, further improving the sand screening rate.

[0015] 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.
[0016] Please see Figure 1 - Figure 5 As shown, Example 1: A screening and mixing device for construction engineering includes a base 1 and a mixing tank 2. The mixing tank 2 is fixedly installed on the top of the base 1. A support frame 3 is fixedly connected to the top of the base 1. A screening frame 4 is provided on the top of the mixing tank 2. One side of the screening frame 4 is fixedly connected to the inner wall of the support frame 3. A dispersing and mixing mechanism is provided on the top of the support frame 3. The dispersing and stirring mechanism includes a motor 5 fixedly installed on the top of the support frame 3. The output end of the motor 5 extends through to the bottom of the support frame 3 and is fixedly connected to a linkage rod 6. The bottom of the linkage rod 6 extends through the screening frame 4 and into the interior of the mixing tank 2. Four stirring rods 7 are fixedly connected to the circumferential side of the linkage rod 6. The screening frame 4 is equipped with a dispersing plate 8, and a dispersing block 9 is fixedly connected to the bottom of the dispersing plate 8. One side of the dispersing plate 8 is fixedly connected to the surface of the linkage rod 6. The vibration mechanism is fixedly installed on the screening frame 4.
[0017] In this embodiment, considering that cement mortar needs to be applied to the wall surface, it is necessary to ensure that there are no foreign objects in the sand. However, the existing mixing device has a poor screening effect and cannot quickly screen the foreign objects in the sand. Therefore, by setting up a dispersing and mixing mechanism, the sand can be poured into the screening frame 4, and at the same time the motor 5 is started. The motor 5 will drive the linkage rod 6 and the mixing rod 7 to rotate. The linkage rod 6 will drive the dispersing plate 8 to rotate, and the dispersing plate 8 will also drive the dispersing block 9 to rotate. During the rotation of the dispersing block 9, the sand will be evenly dispersed on the screening frame 4, avoiding sand accumulation and thus improving the screening rate.
[0018] The number of dispersion blocks 9 is several, and they are evenly distributed at the bottom of the dispersion plate 8.
[0019] In this embodiment, by setting up dispersion blocks 9, the sand can be evenly dispersed by rotating multiple dispersion blocks 9, thereby avoiding sand accumulation.
[0020] Example 2: The vibration mechanism includes two vibrating blocks 10 fixedly connected to both sides of the screening frame 4. An extrusion rod 11 is provided inside the screening frame 4. One end of the extrusion rod 11 extends through to one side of the support frame 3 and is fixedly connected to a linkage block 12. Two striking rods 13 are fixedly connected to one side of the linkage block 12. One end of the striking rod 13 contacts one side of the vibrating block 10. Two tension springs 14 are fixedly connected to one side of the support frame 3, and one end of the tension spring 14 is fixedly connected to one side of the linkage block 12.
[0021] In this embodiment, a vibration mechanism is provided so that during the rotation of the dispersion plate 8, such as... Figure 5 As shown, when the dispersing plate 8 is pressed against the inclined part of the extrusion rod 11, the extrusion rod 11 drives the linkage block 12 and the striking rod 13 to move away from the dispersing plate 8. At the same time, the linkage block 12 will cause the tension spring 14 to be in a stretched state. When the dispersing plate 8 rotates to the point where it is no longer in contact with the extrusion rod 11, the tension generated by the tension spring 14 will cause the linkage block 12 and the striking rod 13 to suddenly reset. The striking rod 13 will strike the vibrating block 10 to generate vibration. The vibration force will be transmitted to the screening frame 4, further increasing the sand screening rate.
[0022] Two guide rods 15 are fixedly connected to one side of the support frame 3, and a guide hole 16 is provided on one side of the linkage block 12 to cooperate with the guide rods 15.
[0023] In this embodiment, by setting guide rod 15 and guide hole 16, the linkage block 12 and the striking rod 13 can be restricted to move only along the trajectory of guide rod 15 and guide hole 16, thereby improving their stability during movement.
[0024] A spring 17 is fixedly connected to one side of the vibrating block 10, and a counterweight 18 is fixedly connected to one end of the spring 17.
[0025] In this embodiment, by setting a spring 17 and a counterweight 18, when the striking rod 13 strikes the vibrating block 10, the counterweight 18 and the spring 17 will also vibrate, thereby improving the vibration effect and further increasing the sand screening rate.
[0026] Both sides of the extrusion rod 11 are sloping and are opposite to the position of the dispersion plate 8.
[0027] In this embodiment, by setting the extrusion rod 11, when the dispersing plate 8 and the sloping part of the extrusion rod 11 are extruded, the extrusion rod 11 drives the linkage block 12 and the striking rod 13 to move away from the dispersing plate 8, thus playing a transmission role.
[0028] Working principle: The user pours sand into the screening frame 4 and starts the motor 5 at the same time. The motor 5 will drive the linkage rod 6 and the stirring rod 7 to rotate. The linkage rod 6 will drive the dispersing plate 8 to rotate. The dispersing plate 8 will also drive the dispersing block 9 to rotate. During the rotation of the dispersing block 9, the sand will be evenly dispersed on the screening frame 4 to avoid sand accumulation and thus improve the screening speed. As the dispersion plate 8 rotates, such as Figure 5 As shown, when the dispersing plate 8 is extruded from the inclined section of the extrusion rod 11, the extrusion rod 11 drives the linkage block 12 and the striking rod 13 to move away from the dispersing plate 8. At the same time, the linkage block 12 will cause the tension spring 14 to be in a stretched state. When the dispersing plate 8 rotates to the point where it is no longer in contact with the extrusion rod 11, the tension generated by the tension spring 14 will cause the linkage block 12 and the striking rod 13 to suddenly reset. The striking rod 13 will strike the vibrating block 10 to generate vibration, and the vibration force will be transmitted to the screening frame 4 to further improve the sand screening rate.
[0029] It should be noted that the motor 5 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 5 are clear to those skilled in the art, so they will not be described in detail.
