Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil detection, and more specifically to a soil sample high-efficiency pre-processing device. Background Art
[0002] Soil testing is to determine whether the representative value of factors affecting soil environmental quality is determined, and to determine environmental quality and its changing trend. After soil collection is completed, it needs to be pre-processed. During the pre-processing operation, the soil needs to be refined to facilitate researchers to conduct inspections. However, the existing soil sample processing device does not have the function of screening, nor does it have the function of crushing coarse materials, resulting in the mixing of coarse and fine materials, which cannot provide researchers with more abundant research materials and cannot produce more powerful explanatory results.
[0003] China Patent Authorization Announcement No.: CN212539875U provides a soil sample pretreatment device, which utilizes a filter plate to screen the soil. Fine material can fall directly from the filter plate into a funnel, and coarse material is placed on the filter plate. The coarse material is located in a crushing box, so that the coarse material can be crushed while retaining the raw material, which can provide researchers with richer research raw materials and help to obtain more powerful explanatory results.
[0004] However, in this solution, since the crushing pieces cannot completely fit with the surface of the filter plate, the coarse materials trapped on the filter plate may not all come into contact with the crushing pieces during the rotation of the crushing pieces. Some of the coarse materials may move to the corners of the filter plate and cannot be crushed, thereby reducing the crushing efficiency. Therefore, an efficient soil sample pretreatment device is proposed to address the above problems. Utility Model Content

The unscreened coarse soil will slide along the filter plate and fall into the crushing component and be crushed by the crushing component. With this arrangement, the coarse material can be crushed while retaining the raw material, which can provide researchers with more abundant research raw materials and ensure that all unscreened coarse soil is crushed to avoid omissions, thereby effectively improving the crushing efficiency.

[0033] Example:
[0034] See also Figure 1-2 A soil sample efficient pretreatment device comprises a box body 1, a filter plate 2 and a collection box 4. The upper end of the box body 1 is open, and a feed plate 7 is fixedly connected to the inner wall of the box body 1. The filter plate 2 is located on the upper side of the feed plate 7, and a plurality of filter screens 3 are installed on the filter plate 2. A vibration component 5 is arranged on the lower side of the filter plate 2. The collection box 4 is located in the inner cavity of the box body 1. A rectangular hole matching the collection box 4 is opened at one end of the box body 1. A crushing component 6 is arranged on the upper side of the collection box 4. The vibration component 5 comprises a vibration motor 504, which is installed at the bottom end of the filter plate 2. The crushing component 6 comprises a pair of crushing rollers 603 matching each other, and both ends of the crushing rollers 603 are rotatably connected to the inner wall of the box body 1.
[0035] The purpose of soil testing is to determine whether the representative value of factors affecting soil environmental quality is determined, and to determine environmental quality and its changing trend. After soil collection is completed, it needs to be pre-treated. During the pre-treatment operation, the soil needs to be refined to facilitate researchers to conduct inspections. In this solution, the user can insert the collection box 4 into the inner cavity of the box body 1 through the rectangular hole, and then place the soil sample on the upper end of the filter plate 2. The filter plate 2 and the feed plate 7 are both placed at an angle, and the soil rolls downward along the inclined surface of the filter plate 2. The smaller fine soil is screened through the filter screen 3 and falls onto the feed plate 7. The feed plate 7 is located at a lower position. The end is located just above the collecting box 4, and the soil slides down the feeding plate 7 into the collecting box 4. The larger coarse soil on the filter plate 2 cannot be screened by the filter net 3 and will continue to slide along the filter plate 2. The lower end of the filter plate 2 is located at the upper end of the crushing component 6, and the coarse soil falls into the crushing component 6 and is crushed by the crushing component 6, and finally becomes small particles of fine soil and falls into the collecting box 4 to be collected. With this arrangement, the coarse material can be crushed while retaining the raw material, which can provide researchers with richer research raw materials and ensure that all coarse soil that has not been screened is crushed, effectively improving the crushing efficiency.
[0036] See also Figure 2-3The vibration assembly 5 also includes a first base 501 and a second base 502, both of which are fixedly connected to the inner wall of the box body 1, and a pair of springs 503 are fixedly connected to the first base 501 and the second base 502 respectively, and the top ends of the multiple springs 503 are fixedly connected to the bottom end of the filter plate 2.
[0037] In this solution, the user can start the vibration motor 504 to vibrate, thereby driving the filter plate 2 to vibrate. The filter plate 2 vibrates at a high frequency under the elastic force of multiple springs 503, which can effectively drive the soil on the upper end of the filter plate 2 to vibrate, so that during the soil sliding process, the fine soil can be more smoothly screened by the filter net 3, and at the same time, some coarse soil can be decomposed and broken up during the vibration, which is beneficial to subsequent crushing.
[0038] See also Figure 3-4 The crushing assembly 6 also includes a servo motor 601, which is installed at the outer end of the box body 1, and the output end of the servo motor 601 extends to the inner cavity of the box body 1 and is fixedly connected to a worm 602. The end of the worm 602 away from the servo motor 601 is rotatably connected to the second base 502, and a pair of symmetrical and opposite spiral lines are engraved on the outer surface of the worm 602. The outer ends of a pair of crushing rollers 603 are fixedly connected to worm wheels 604, and the pair of worm wheels 604 are meshed with the worm 602.
[0039] When the user starts the servo motor 601, the worm 602 can be driven to rotate, and then the pair of worm gears 604 can be driven to rotate synchronously in opposite directions. The pair of worm gears 604 drive the pair of crushing rollers 603 to rotate. One end of the filter plate 2 is located on the upper side between the pair of crushing rollers 603. The coarse soil falling from the filter plate 2 will fall between the pair of crushing rollers 603 and be squeezed and crushed by the rotation of the pair of crushing rollers 603, and finally become small particles of soil that fall from between the pair of crushing rollers 603 into the collection box 4.
[0040] Working principle:
[0041] When in use, the user needs to start the vibration motor 504 to vibrate, drive the filter plate 2 to vibrate, and the filter plate 2 performs high-frequency vibration under the elastic force of multiple springs 503, and at the same time start the servo motor 601 to drive the worm 602 to rotate, thereby driving a pair of worm gears 604 to rotate synchronously in opposite directions, and the pair of worm gears 604 drive a pair of crushing rollers 603 to rotate, then the user inserts the collection box 4 into the inner cavity of the box body 1 through the rectangular hole, and then places the soil sample on the upper end of the filter plate 2, and the soil rolls downward along the inclined surface of the filter plate 2. The smaller fine soil is screened through the filter mesh 3 and falls onto the discharge plate 7. The soil slides down the discharge plate 7 into the collecting box 4. The vibration of the filter plate 2 can vibrate the soil, so that the fine soil is screened by the filter mesh 3 more smoothly, and at the same time, some coarse soil is decomposed and broken up during the vibration. The coarse soil cannot be screened by the filter mesh 3, and will continue to slide down the filter plate 2, falling between the pair of crushing rollers 603, and being squeezed and crushed by the rotation of the pair of crushing rollers 603, and finally becoming small particles of soil that fall from between the pair of crushing rollers 603 into the collecting box 4.
[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
