Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0036] Reference Figure 1-5 As shown in the embodiment of this utility model, a simple aggregate screening device for engineering experiments is proposed, including a base 1, a support rod 2, and a vibrating screen assembly 3, wherein:

[0037] The base 1 has a hollow cavity inside, and the base 1 has a filling hole 11 that connects to the cavity. Fine sand, gravel and other objects can be filled into the cavity through the filling hole 11 to ensure the stability of the base 1.

[0038] One end of the support rod 2 is detachably connected to the base 1;

[0039] The vibrating screen assembly 3 includes a screen frame 31, a screen base plate 32, a buffer 33, a limiting member 34, a vibrating motor 35, a power supply 36, and a screen mesh 37. The screen base plate 32 is installed at the bottom of the screen frame 31. The buffer 33 is installed at the bottom of the screen frame 31 and is connected to the other end of the support rod 2. One end of the limiting member 34 is connected to the screen frame 31, and the other end is slidably installed on the support rod 2. The vibrating motor 35 is installed at the bottom of the screen base plate 32. The power supply 36 is connected to the vibrating motor 35 and is a portable battery. The screen mesh 37 is installed inside the screen frame 31 and can be a standard screen. The buffer 33 can be a spring. The vibrating motor 35 is connected to the bottom of the screen base plate 32 by screws to ensure the vibration amplitude of the screen frame 31 during operation.

[0040] The simple aggregate screening device for engineering experiments proposed in this embodiment is detachably connected to the base 1 at one end of the support rod 2, and connected to the bottom of the screen frame 31 at the other end through the buffer 33. It is easy to disassemble and install, disassemble for transportation, and reassemble for use, making it easy to carry. The base 1 has a hollow cavity, and the base 1 has a filling hole 11 that connects to the cavity. During transportation, the hollow design of the base 1 reduces the overall weight, making it easy to move and transport. When in use, fine sand, fine stones, or other objects are poured into the cavity through the filling hole 11 to ensure the stability of the base 1. It can be used in the field or in complex environments, meeting the screening needs of construction sites.

[0041] In some embodiments, the limiting member 34 includes a connecting rod 341 and a limiting ring 342. The two ends of the connecting rod 341 are connected to the screen frame 31 and the limiting ring 342, respectively. The limiting ring 342 is sleeved on the support rod 2. The connecting rod 341 is perpendicular to the limiting ring 342. The inner diameter of the limiting ring 342 is larger than the outer diameter of the support rod 2, which can limit the position of the screen frame 31 and ensure stability during vibration.

[0042] In some embodiments, the vibrating screen assembly 3 further includes a foot pedal 4, which is detachably connected to the screen frame 31. The screen frame 31 has a threaded connection on its side, and the foot pedal 4 has a connecting thread. The foot pedal 4 is detachably connected to the screen frame 31 by connecting to the threaded connection. When the device is being carried out and the power supply 36 has run out of power, the foot pedal 4 connects to the screen frame 31, and the screen frame 31 vibrates when the foot is pressed, improving the practicality and reliability of the device.

[0043] In some embodiments, the foot pedal 4 includes a first connecting portion 41, a second connecting portion 42, and a third connecting portion 43. The first connecting portion 41 is connected to the side wall of the sieve frame 31 and is arranged parallel to the upper surface of the base 1. The second connecting portion 42 is connected to both the first connecting portion 41 and the third connecting portion 43, and the third connecting portion 43 is parallel to the first connecting portion 41. The simple aggregate screening device for engineering experiments also includes a mounting plate 5 and a reset member 6. The mounting plate 5 is arranged parallel to the third connecting portion 43, and the reset member 6 is installed between the third connecting portion 43 and the mounting plate 5. When using the foot pedal 4, lifting the foot allows the foot pedal 4 to quickly reset, facilitating the next foot pedaling, thereby allowing the sieve frame 31 to vibrate repeatedly, improving the reliability and stability of the device. The reset member 6 can be a spring.

[0044] In some embodiments, four support rods 2 are provided, and the four support rods 2 are arranged in pairs, with the two support rods 2 in each pair being symmetrically arranged. By symmetrically arranging the two support rods 2 in each pair, the supporting force on the screen frame 31 is more uniform, the supporting effect on the screen frame 31 is more stable, and the reliability and stability of the device are improved.

[0045] In some embodiments, the vibrating screen assembly 3 further includes a protective cover 38, which is mounted on the screen frame 31. By mounting the protective cover 38 above the screen frame 31, the material collected on the screen mesh 37 is shielded, preventing material from flying out and causing waste during the screening process, thus improving the reliability of the device.

[0046] In some embodiments, the bottom end of the support rod 2 is provided with an external thread 21, and the base 1 is provided with a threaded hole 12. The external thread 21 is threadedly connected to the threaded hole 12. By threading the external thread 21 to the threaded hole 12, the support rod 2 and the base 1 are detachably connected. The connection is reliable, convenient and quick, easy to assemble and disassemble, and improves the portability of the device.

[0047] In other embodiments, the support rod 2 and the base 1 can be connected by other means such as snap-fit ​​connection, as long as the support rod 2 and the base 1 can be detachably connected.

[0048] In some embodiments, the base 1, the support rod 2, and the screen frame 31 are all made of aluminum alloy. Choosing aluminum alloy reduces the overall weight of the device and improves its portability. Of course, the base 1, the support rod 2, and the screen frame 31 can also be made of other lightweight materials.

[0049] The working principle of the simple aggregate screening device for engineering experiments proposed in this embodiment is as follows: fine sand, fine stones, and other objects are poured into the cavity through the filling hole 11. The screen 37 is placed on the screen frame 31, and the aggregate is poured onto the screen 37. Then, the protective cover 38 is covered, and the vibration motor is started, which drives the screen bottom plate 32 to vibrate. At the same time, the screen frame 31 and the screen 37 vibrate, which greatly shortens the screening time of the aggregate. It can be used in the field or in complex environments to meet the screening needs of construction sites. Through the design of the power supply 36 and the vibration motor 35, the device can be used outdoors. The vibration motor 35 can be connected to the power supply 36 for a period of time. The ingenious design of the foot pedal 4 allows the screen frame 31 to vibrate when the power supply 36 is out of power. This saves effort and effectively speeds up the screening of aggregate.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
