[0040] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

Therefore, the above terms should not be understood as limiting the present invention.

[0042] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0043] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections, or communication; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0044] Combine Figure 1 and Figure 2 A soil sample detection system 100 according to a preferred embodiment of the present invention will be described in detail below, wherein the soil sample detection system 100 includes a first weighing device 1, a dewatering device 2, a second weighing device 3, a transfer device 4 and a data processing device 5.

[0045] The first weighing device 1, the dewatering device 2, and the second weighing device 3 are arranged in sequence. The first weighing device 1 is used to weigh the soil container 200 containing the soil sample before dewatering. The dewatering device 2 is used to remove moisture from the soil sample. The second weighing device 3 is used to weigh the soil container 200 containing the soil sample after dewatering.

[0046] The transfer device 4 is used to sequentially transfer the soil container 200 containing the soil sample to be tested to the dewatering device 2 and the second weighing device 3 after the first weighing device 1 has weighed the soil sample. In other words, after the first weighing device 1 has weighed the soil sample, the soil container 200 is first transferred to the dewatering device 2 to remove moisture from the soil sample, and then transferred to the second weighing device 3 to measure the weight after dewatering.

[0047] The data processing device 5 is connected to the first weighing device 1 and the second weighing device 3 respectively to determine the moisture content of the soil sample to be tested according to the weights weighed by the first weighing device 1 and the second weighing device 3 .

[0048] In this way, after the soil sample detection system 100 of the present invention is weighed by the first weighing device 1, the soil container 200 is automatically transferred to the dewatering device 2 and the second weighing device 3 in sequence through the transferring device 4. When transferred to the dewatering device 2, the water is removed by the dewatering device 2. When transferred to the second weighing device 3, the weight after dewatering is weighed by the second weighing device 3. At the same time, after both weighings are completed, the weighing data is processed in real time by the data processing device 5, so that the moisture content of the soil sample to be tested is quickly obtained.

[0049] Therefore, the soil sample detection system 100 of the present invention can achieve the purpose of quickly detecting the moisture content of the soil sample of the building or highway foundation, and then can quickly determine whether the construction quality of the building or highway foundation meets the requirements based on the moisture content of the soil sample of the building or highway foundation, with high detection efficiency and small detection error.

[0050] Specifically, the first weighing device 1 and the second weighing device 3 may be electronic scales. The dewatering device 2 may be an oven. The data processing device 5 may be a computer. It is understood that the first weighing device 1, the dewatering device 2, and the second weighing device 3 of the present invention include, but are not limited to, the above. Devices capable of weighing, removing moisture from soil samples, and performing data processing are also applicable to the present invention.

[0051] Specifically, the moisture content of the soil sample to be tested can be obtained by the data processing device 5 according to the following formula: (weight of the soil container 200 containing the soil sample to be tested - weight of the soil container 200 containing the soil sample to be tested after dehydration) / (weight of the soil container 200 containing the soil sample to be tested after dehydration - known mass of the soil container 200 alone) * 100%.

[0052] Further, combined with Figure 2The first weighing device 1, the dewatering device 2, and the second weighing device 3 together form a transfer area. The transfer device 4 is disposed in the transfer area. The transfer device 4 includes a transfer gripper 41 and a transfer base 42. The transfer gripper hand 41 is rotatably disposed on the transfer base 42. The transfer gripper hand 41 has a gripping opening 4101 for gripping and transferring the soil container 200. Thus, after the transfer gripper hand 41 grips the soil container 200, it can rotate accordingly to transfer the soil container 200 to the dewatering device 2 and the second weighing device 3.

[0053] According to some preferred embodiments of the present invention, Figure 1 、 Figures 3 to 6 The soil sample detection system 100 includes a conveying device 6, at least one transfer device 7 and at least one pushing device 8.

[0054] The conveying device 6 has a conveyor belt 61, and the conveyor belt 61 has a feeding end 611 and a feeding end 612, so as to transport the soil sampler 300 and the soil container 200 for obtaining the soil sample to be tested along the conveying direction from the feeding end 611 to the feeding end 612. Figure 3 , a soil taking channel 301 is formed in the soil taking device 300 and runs axially through the soil taking device 300, for loading the soil sample to be tested. A holding cavity 202 with a holding opening 201 at the top is formed in the soil container 200. The first weighing device 1 is arranged on one side of the conveyor belt 61 and close to the discharge end 612. That is to say, after the soil taking device 300 takes soil, the soil taking device 300 loaded with the soil sample to be tested in the soil taking channel 301 and the soil container 200 required for testing can be directly placed on the conveyor belt 61, and the conveyor belt 61 drives the soil taking device 300 and the soil container 200 to move along the conveying direction from the loading end 611 to the discharge end 612, so as to be transported to the first weighing device 1.

[0055] Along the conveying direction, the transfer device 7 is disposed upstream of the first weighing device 1 and is used to transfer at least part of the soil sample to be tested from the soil sampling channel 301 to the soil storage chamber 202 when the soil sampler 300 and the soil container 200 are conveyed to the transfer position. In other words, when the soil sampler 300 and the soil container 200 are conveyed to the first weighing device 1, the soil sampler 300 and the soil container 200 will first pass through the transfer device 7. At this time, the soil sample to be tested is transferred from the soil sampling channel 301 of the soil sampler 300 to the soil storage chamber 201 of the soil container 200 by the transfer device 7 to facilitate subsequent weighing.

[0056] Combine Figure 1 and Figure 4The pushing device 8 and the first weighing device 1 are respectively arranged on opposite sides of the conveyor belt 61, and the pushing device 8 is aligned with the first weighing device 1. When the soil container 200 is transported to the pushing position, the soil container 200 containing the soil sample to be tested is pushed to the first weighing device 1 in a direction perpendicular to the conveying direction for weighing. In other words, when the soil container 300 and the soil container 200 are transported to the first weighing device 1, the soil container 300 and the soil container 200 will pass through the transfer device 7 and then the pushing device 8. At this time, the pushing device 8 will directly push the soil container 200 to the upper surface of the first weighing device 1 for weighing by the first weighing device 1.

[0057] Further, combined with Figure 1 The conveying device 6 includes at least one conveying and placing seat 62, which is disposed on the surface of the conveyor belt 61. A placement groove is formed in the conveying and placing seat 62, which is adapted to accommodate the soil extractor 300 and for placing the soil extractor 300. The surface of the conveyor belt 61 is formed with at least one chute 613 extending perpendicular to the conveying direction. The chute 613 is adjacent to the conveying and placing seat 62, and the soil container 200 is slidably disposed in the chute 613.

[0058] In this way, during the process of conveying the soil extractor 300 and the soil container 200 by the conveyor belt 61, the soil extractor 300 and the soil container 200 will not shake or be easily separated, thereby improving the conveying stability of the soil extractor 300 and the soil container 200. In addition, because the chute 613 can limit the sliding movement of the soil container 200, the movement stability of the pushing device 8 when pushing the soil container 200 can be improved.

[0059] Furthermore, each of the transport and placement seats 62 can be equipped with two chutes 613 at each end to accommodate two soil containers 200. Thus, two soil containers 200 can be configured for each soil extractor 300. This allows the average of the two moisture contents to be calculated as the final moisture content during subsequent testing, resulting in higher detection accuracy.

[0060] Furthermore, the plurality of conveying and placing seats 62 are arranged at intervals along the conveying direction of the conveyor belt 61. In this way, multiple samples to be tested can be transported at one time for testing, thereby realizing the streamlined testing of the soil samples to be tested by the soil sample testing system 100 and improving the efficiency of testing large batches of soil samples to be tested.

[0061] Furthermore, the soil taker 300 may be a ring-type soil taker 300, and the number of the pushing devices 8 may be two. Specifically, the pushing devices 8 may be cylinders.

[0062] Further, combined with Figure 1 and Figure 5 The transfer device 7 includes a transfer lifting drive member 71, a rotary propeller 72, and a cutter head 73. When the soil collector 300 and the soil container 200 are transported to the transfer position, the soil container 200 is close to the end of the soil collecting passage 301. The transfer lifting drive member 71 is connected to the cutter head 73 and the rotary propeller 72. When the soil collector 300 and the soil container 200 are in the transfer position, the cutter head 73 and the rotary propeller 72 are driven to descend simultaneously so that the cutter head 73 approaches and aligns with the end of the soil collecting passage 301. When the soil collector 300 and the soil container 200 leave the transfer position, the cutter head 73 and the rotary propeller 72 are driven to rise simultaneously so that the cutter head 73 is away from the soil collecting passage 301, thereby facilitating the transport of the next soil collector 300 and the soil container 200 to the transfer position.

[0063] The rotary propeller 72 is connected to the soil-scraping cutter head 73. When the soil-scraping cutter head 73 is aligned with the end of the soil-scraping channel 301, the soil-scraping cutter head 73 is driven to rotate forward, so that the soil-scraping cutter head 73 rotates and extends into the soil-scraping channel 301, thereby scraping the soil sample to be tested out of the soil-scraping channel 301 and transferring it to the soil container 200. After the soil-scraping cutter head 73 has scraped the soil, the soil-scraping cutter head 73 is driven to rotate backward, so that the soil-scraping cutter head 73 is away from the soil-scraping channel 301. This facilitates the continued transportation of the soil sampler 300 and the soil container 200 containing the soil sample to be tested along the conveying direction after scraping the soil, facilitating subsequent weighing and collection and processing of the soil sampler 300.

[0064] Furthermore, there may be two transfer devices 7, which are spaced apart from each other, so that soil can be dug from two ends of the soil sampler 300, thereby obtaining two soil samples to be tested for detection.

[0065] Furthermore, the transfer lifting drive member 71 is a transfer drive motor, and the rotary propeller 72 is a screw propulsion motor. Figure 6 The shovel head 73 is constructed as a spiral cutter head with multiple shovel blades 731 arranged radially. As a result, after the transfer drive motor drives the auger motor and the shovel head 73 to rotate downward, the auger motor drives the multiple shovel blades 731 to rotate spirally forward, thereby improving transfer efficiency.

[0066] According to some preferred embodiments of the present invention, Figure 1 and Figure 7 The soil sample detection system 100 includes a trimming device 9, a material moving device 10 and a pushing device 11.

[0067] The trimming device 9 is disposed on one side of the conveyor belt 61, upstream of the transfer device 7 in the conveying direction. When the soil sampler 300 and the soil container 200 are conveyed to the trimming position, the soil container 200 moves away from the end of the soil sampler 300, and the trimming device 9 trims the end edge of the soil sample to be tested to be flush with the end edge of the soil sampler 300. In this way, the soil container 200 does not affect the trimming process of the trimming device 9, allowing the trimming process to proceed smoothly and stably.

[0068] The material transfer device 10 is arranged between the trimming device 9 and the second weighing device 3 to transfer the trimmed soil sampler 300 to the second weighing device 3 to weigh the weight of the soil sampler 300 loaded with the soil sample to be tested, and transfer it back after weighing.

[0069] The data processing device 5 is connected to the second weighing device 3 to determine the wet density of the soil sample to be tested based on the weight weighed by the soil sampler 300. In this way, a high-efficiency detection of the wet density of the soil sample to be tested is achieved.

[0070] Specifically, the total mass of the soil sampler 300 and the soil sample to be tested minus the known mass of the soil sampler 300 alone = the mass of the soil sample to be tested; the mass of the soil sample to be tested / the known volume of the soil sampling channel 301 within the soil sampler 300 = the wet soil density. Simultaneously, the data processing device 5 can also determine the dry density of the soil sample to be tested based on the wet density and moisture content: dry density = wet density / (1 + moisture content).

[0071] Further, combined with Figure 7 The trimming device 9 includes two spaced-apart cutting trimmers 91, each of which includes a cutting lift drive 911 and a cutting blade 912. The cutting lift drive 911 is connected to the cutting blade 912, so that when the soil taker 300 and the soil container 200 are in the trimming position, the cutting blade 912 is driven to descend so that the cutting blade 912 approaches and aligns with the end edge of the soil taker 300, and drives the cutting blade 912 to cut excess soil extending out of the soil taker 300 so that the end edge of the soil sample to be tested is flush with the end edge of the soil taker 300. When the soil taker 300 and the soil container 200 leave the trimming position, the cutting blade 912 is driven to ascend so as to move away from the soil taker 300 and no longer cut.

[0072] Furthermore, the material moving device 10 may be a robot.

[0073] According to some preferred embodiments of the present invention, Figure 1 The soil sample detection system 100 includes a pushing device 11. Along the conveying direction, the pushing device 11 is arranged between the transfer device 7 and the trimming device 9. When the soil taker 300 and the soil container 200 are conveyed to the pushing position, the pushing device 11 pushes the soil container 200 to move in a direction perpendicular to the conveying direction so that the soil container 200 is close to the end of the soil taker 300, so that the soil dug out by the transfer device 7 subsequently falls into the soil container 200 as much as possible.

[0074] Specifically, the pushing device 11 can be a cylinder.

[0075] According to some preferred embodiments of the present invention, the soil sample detection system 100 includes a collecting box 12, which is close to the discharge end 612. A collecting cavity with a collecting port 1201 on the top is formed in the collecting box 12, and the height of the collecting port 1201 is lower than the height of the upper surface of the conveyor belt 61, so as to facilitate the collection of the soil samples to be tested and the soil sampler 300 transported to the discharge end 612 of the conveyor belt 61.

[0076] According to some preferred embodiments of the present invention, Figure 1 The soil sample detection system 100 includes a first scanning device 13 and a second scanning device 14. The outer surface of the soil sampler 300 is provided with a sampling mark code, and the outer surface of the soil container 200 is provided with a detection mark code. The first scanning device 13 is used to scan the sampling scanning code, and the second scanning device 14 is used to scan the detection mark code. The data processing device 5 is connected to the first scanning device 13 and the second scanning device 14 respectively to correspond the detection mark code and the sampling mark code, so that the collected soil samples can be corresponded to the corresponding test results, which is convenient for corresponding statistics of the moisture content of each soil sample to be tested.

[0077] Specifically, the first scanning device 13 and the second scanning device 14 may be scanners.

[0078] The present invention also provides a soil sample detection method, combining Figures 1 to 2 The soil sample is detected by the soil sample detection system as described above, and the soil sample detection method includes the following steps:

[0079] S10: The soil container 200 containing the soil sample to be tested is weighed for the first time by the first weighing device 1 .

[0080] S20: The soil container 200 after the first weighing is transferred to the dewatering device 2 by the transfer device 4 .
