Vibrators are fixedly connected to both sides of the shell. The shell is inclined above the base plate, and a screening mechanism is installed inside the shell.

[0003] The aforementioned existing technology uses a drive motor to achieve synchronous counter-movement of the upper and lower screen frames, causing the soil inside the screen frames to continuously shake, which helps the soil spread out and increases the probability of soil passing through the screen holes, thereby improving soil screening efficiency. However, in the actual screening process, some moist soil may adhere to the screen mesh, causing blockage, and some clumps of soil may not be effectively screened out. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid drying and screening device for soil testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rapid drying and screening device for soil testing includes a receiving box and a screening frame disposed above the receiving box. Elastic support members are provided at the four corners of the screening frame. A screening mechanism is provided on the screening frame, and a fixed cover is fixedly connected to the top outer wall of the screening frame by bolts. The screening mechanism includes a hot air drying component mounted on a fixed cover, a screen fixedly connected to the bottom of the screening frame, and a vibration motor fixedly installed on the outer wall of one side of the screening frame. The hot air drying assembly includes a powerful hot air blower fixedly connected to the outer wall of the rear side of the fixed cover via a blower base, and four blower hoods fixedly connected to the top of the fixed cover and distributed at equal intervals.

[0006] As a further description of the above technical solution, the elastic support includes a support block, a connecting block welded to the outer wall of the screening frame, and a connecting spring welded between the support block and the connecting block.

[0007] As a further description of the above technical solution, the tops of the four blower hoods are fixedly connected to the same diversion pipe, and the air outlet of the powerful hot air blower is fixedly connected to the diversion pipe through a pipe.

[0008] As a further description of the above technical solution, each of the four blower covers is provided with a dispersant below it, and the top of the fixed cover is fixedly connected to a feed hopper.

[0009] As a further description of the above technical solution, the dispersant includes a bracket fixedly connected to the bottom outer wall of the blower hood, a drive shaft, an impeller fixedly connected to the top of the drive shaft, and a dispersing curved blade fixedly connected to the bottom of the drive shaft.

[0011] As a further description of the above technical solution, a guide frame is welded to the outer wall of the other side of the screening frame.

[0012] The beneficial effects of this utility model are as follows: 1. Equipped with a hot air drying component, during the soil vibration screening process, a powerful hot air blower sends out hot air, which is effectively diverted through the diversion pipe and flows into each blower hood. Finally, each blower hood blows the hot air evenly into the screening frame, so that the soil can be fully dried during the vibration process. This avoids the situation where some damp soil adheres to the screen and causes blockage, which is conducive to improving the soil screening efficiency. 2. Each of the four blower hoods of this utility model is equipped with a dispersant below it. The airflow at the blower hood will cause the impeller to rotate, and then the dispersing curved blade at the bottom of the drive shaft will rotate so that the soil can be fully dispersed during the vibration and forward movement.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, referring to Figure 1-3 A rapid drying and screening device for soil testing includes a receiving box 1 for collecting soil and a screening frame 3 disposed above the receiving box 1. A fixing cover 6 is fixedly connected to the top outer wall of the screening frame 3 by bolts, and a feeding hopper 7 is fixedly connected to the top of the fixing cover 6. Specifically, each of the four corners of the screening frame 3 is provided with an elastic support 2. The elastic support 2 includes a support block 201, a connecting block 202 welded to the outer wall of the screening frame 3, and a connecting spring 203 welded between the support block 201 and the connecting block 202. Specifically, the screening frame 3 is equipped with a screening mechanism, which includes a hot air drying component on the fixed cover 6, a screen 4 fixedly connected to the bottom of the screening frame 3, and a vibration motor 5 fixedly installed on one side of the outer wall of the screening frame 3. A guide frame 16 is welded to the other side of the outer wall of the screening frame 3. Furthermore, the hot air drying assembly includes a powerful hot air blower 9 fixedly connected to the rear outer wall of the fixed cover 6 via a blower base 8 and four air blowing hoods 10 fixedly connected to the top of the fixed cover 6 and distributed at equal distances. The top of the four air blowing hoods 10 is fixedly connected to the same diversion pipe 11, and the air outlet of the powerful hot air blower 9 is fixedly connected to the diversion pipe 11 via a pipe. The working principle of this embodiment is as follows: First, the vibration motor 5 and the four elastic support members 2 work together to make the screen 4 in the screening frame 3 vibrate. The soil falling from the feed hopper 7 onto the surface of the screen 4 will move forward due to the vibration. In this process, the vibration screening effect can be achieved. The impurities in the soil will remain on the surface of the screen 4, and the soil will be screened out by the screen 4 and collected by the receiving box 1. Finally, the screened impurities will be discharged from the guide frame 16. Second, during the vibration screening of the soil, the powerful hot air blower 9 sends out hot air and it flows into each blower hood 10 through the effective diversion pipe 11. Finally, each blower hood 10 blows the hot air evenly into the screening frame 3, so that the soil can be fully dried during the vibration. This can avoid the situation where some wet soil adheres to the screen 4 and easily causes blockage, which is beneficial to improving the soil screening efficiency.

[0017] Example 2, refer to Figure 3-5 This embodiment is an optimization based on embodiment 1. Specifically, each of the four blower hoods 10 is equipped with a dispersant below it. The dispersant includes a bracket 12 fixedly connected to the bottom outer wall of the blower hood 10, a drive shaft 13, an impeller 14 fixedly connected to the top of the drive shaft 13, and a dispersing bend 15 fixedly connected to the bottom of the drive shaft 13. Furthermore, the impeller 14 is located inside the blower hood 10, and the drive shaft 13 is connected to the central inner wall of the bracket 12 through a bearing. This dispersant breaks up some clumps of soil by converting the flow power of the airflow into the rotational power of the dispersing bend 15. This method does not require electric drive, effectively saves the cost of use, and has the effect of being economical and environmentally friendly. The working principle of this embodiment is as follows: the airflow at the blower hood 10 will cause the impeller 14 to rotate, and then the dispersing curved blade 15 at the bottom of the drive shaft 13 will rotate so that the soil can be fully dispersed during the vibration and forward movement, thereby avoiding the situation where some clumps of soil cannot be effectively screened out, and thus further improving the soil screening efficiency.
