[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment: A sample crusher for soil testing, such as Figures 1 to 4 As shown, it includes a first funnel 1, a support frame 2 and a collecting box 3. A first filter screen 7 is arranged below the first funnel 1, a second box body 5 is arranged below the first filter screen 7, and a first box body 4 is arranged below the second box body 5. Protective shells 6 are fixed on both sides above the first box body 4, and motors 11 are arranged inside the two protective shells 6. A belt 13 is arranged on the transmission shaft of the protective shell 6. A rolling roller 12 is connected to the side of the belt 13 away from the motor 11, and the number of the rolling roller 12 and the belt 13 are both two. At the same time, a second filter screen 8 is also arranged at the bottom of the first box body 4. The rolling roller 12 is arranged to fully crush the soil sample, and the use of the motor 11 ensures that it has a continuous power to stably crush the sample, thereby ensuring the operation efficiency of the device. At the same time, the filter screen is arranged to remove impurities that do not belong to the soil in the sample twice to avoid affecting the final sample and the test results.

[0024] A vibrator 10 is fixed on the top of the support frame 2 near the inner wall of the second box body 5. The vibrator 10 is provided to better promote the falling of soil samples and facilitate the screening process. Continuous vibration can ensure that the soil continues to maintain a trend of falling under the dual effects of gravity and vibration, which reduces a certain amount of energy costs in the process and improves the practicality of the device.

[0025] A second funnel 9 is provided below the first box body 4, and the collecting box 3 is located just below the outlet of the second funnel 9. The second funnel 9 as a discharge port mainly serves to gather the final sample, avoiding sample splashing or other situations that are not conducive to collection due to the discharge port being too wide. At the same time, the collecting box 3 located just below the second funnel 9 is for timely collection and preservation in conjunction with the discharge, which improves the rigor of the device and ensures the scientific nature of the final sample.

[0026] The first filter 7 is a high-density filtering device, which is designed to screen the sample quality in the first step, and block the sand or plant debris that are not needed for the test outside the device to avoid the above factors causing uneven final sample quality, thereby affecting the final test results.

[0027] The two rolling rollers 12 are in close contact with each other and are respectively connected to the corresponding motor 11. The rolling rollers 12 in close contact with each other are for better squeezing and crushing the soil. If the distance between the two is large, some larger materials or sand and gravel will fall into the inside, affecting the final sampling and detection results. At the same time, the separately arranged power system can make the movement directions of the two rolling rollers 12 opposite, and the crushed soil will be transferred to the processing process below during the crushing process, thereby improving the practical value of the device.

[0028] Two small raised baffles are provided at the bottom of the support frame 2, and the length between the two raised baffles is equal to the width of the collecting box 3. This design is to better fix the collecting box 3 directly under the second funnel 9, avoid the position displacement caused by the vibration of the vibrator 10, thereby affecting the result of collecting samples, and improve the practicality of the device.

[0029] The working principle of this utility model:

[0030] During use, the device needs to be powered on as a whole first, and then the dried soil is placed in the first funnel 1. Under the vibration of the vibrator 10, the soil will fall through the first filter screen 7. When passing through the first filter screen 7, some sand or plant debris will be directly retained above the first filter screen 7. The screened soil will continue to fall under the influence of gravity. When it passes under the second box body 5, it will be gathered by the funnel-shaped bottom to the top of the two rolling rollers 12. The soil will continue to fall. When passing between the two rolling rollers 12, it will be subjected to a large squeezing force between the two closely connected rolling rollers 12, causing the soil to break. After that, it will suddenly pass through the first box body 4 and fall on the second filter screen 8. Under the continuous operation of the vibrator 10, it will suddenly be screened again. After screening, the most uniform and fine soil will fall into the collection box 3, and the crushing process is completed.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above implementation regulations. The above implementation regulations and the description only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
