[0001] The invention relates to the technical field of soil detection, in particular to a deep multi-point soil parameter rapid detection device. Background Art

[0002] Soil is an important research object in the fields of agricultural production, ecological environment protection and geological exploration. Its physical, chemical and biological properties directly affect the growth of crops, environmental sustainability and the rational use of resources. Therefore, it is of great significance to quickly and accurately obtain soil parameters (such as water content, organic matter content, pH value, nutrient content, etc.) for precision agriculture, environmental monitoring and land resource management.

[0003] However, when conducting soil detection, traditional soil detection methods usually require taking out soil samples and then using spectral sensors to perform parameter analysis.

In addition, during the drilling process of soil samples, soils at multiple points are very likely to be cross-mixed, which in turn leads to a decrease in the accuracy of the detection results.

[0017] When the rubber block is turned into the measuring window, it can also push out the soil that enters the edge of the measuring window due to soil collapse during the detection of the spectral sensor, thereby reducing the soil parameter error caused by the next soil detection. After the detection is completed, the rubber scraper ring can scrape off the soil sticking to the surface of the detection tube, thereby saving the trouble of cleaning the detection tube for the staff.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, reference Figures 1 to 4, which is the first embodiment of the present invention, and provides a deep multi-point soil parameter rapid detection device, which can realize rapid parameter measurement of multiple points in the soil, and avoid the cross-mixing of soil at multiple points, thereby ensuring the accuracy of the detection result, including a detection mechanism 100, which includes a mobile frame 101, and a fixed plate 107 arranged above the mobile frame 101, a detection tube 110 is arranged at the lower right side of the fixed plate 107, and a lifting component for driving the detection tube 110 to insert into the soil for detection is arranged on the side of the mobile frame 101 away from the detection tube 110. The detection tube 110 is provided with a multi-point detection component for detecting soil at multiple points, and a switching mechanism 200 is arranged above the detection tube 110. The switching mechanism 200 includes a glass tube 201 arranged inside the detection tube 110, and a switching component arranged above the detection tube 110 for rotating and switching the glass tube 201, and a cleaning component arranged outside the detection tube 110 for clearing the soil on the surface of the detection tube 110.

[0033] In this embodiment, by pushing the mobile frame 101 to the designated detection position, and then controlling the lifting assembly on the mobile frame 101, the lifting assembly drives the fixed plate 107 to move downward, and then the fixed plate 107 drives the detection tube 110 to be inserted into the soil, so that the multi-point detection assembly inside the detection tube 110 detects the soil at multiple different positions, thereby realizing rapid parameter measurement of multiple positions in the soil, avoiding cross-mixing of soil at multiple points, and thus ensuring the accuracy of the detection results. At the same time, when the fixed plate 107 moves down to its position, the switching assembly will be linked to control the switching of the glass tube 201, thereby realizing the process of avoiding the influence of external soil entering the sensor inside the multi-point detection assembly during the downward movement of the detection tube 110, and at the same time reducing the damage of the soil to the surface of the glass tube 201 during the upward movement and resetting of the detection tube 110, thereby reducing the error caused by the scratches on the surface of the glass tube 201 on the sensor detection. When the fixed plate 107 moves up and resetting, the cleaning assembly can also scrape the soil sticking to the surface of the detection tube 110, thereby saving the trouble of the staff to clean the detection tube 110.

[0034] Specifically, the lifting assembly includes a column 102 arranged above the moving frame 101, and the column 102 is set in four.

The servo motor 105 is detachably connected to the upper end of the column 102, and a screw rod 106 is installed at the output end of the servo motor 105. A screw rod sleeve 108 is fixedly installed on the side of the fixed plate 107 close to the screw rod 106. Slide blocks 104 are fixedly installed on the front and rear sides of the fixed plate 107. A sliding groove 103 is opened on the inner side of the column 102. The size of the slider 104 is adapted to the size of the sliding groove 103, and the slider 104 is slidably connected to the sliding groove 103. A tool box 109 is detachably installed in the middle of the upper end of the fixed plate 107, and the screw rod 106 is threadedly connected to the screw rod sleeve 108.

[0035] In this embodiment, the column 102 is fixedly connected to the upper part of the mobile frame 101 by bolts. During detection, the servo motor 105 is turned on, and the servo motor 105 drives the screw rod 106 to rotate forward. The screw rod 106 cooperates with the screw rod sleeve 108 to drive the fixed plate 107 to move downward, so that the fixed plate 107 drives the two detection tubes 110 on the right to follow the movement, so that the detection tubes 110 can be inserted into the soil, so as to achieve multi-point detection effect of the soil in two directions in the detection area, and avoid the trouble of drilling and detecting the soil at different points, thereby improving the detection efficiency of the soil, and avoiding the cross-mixing of the soil in the process of soil sampling at multiple points, thereby ensuring the accuracy of the detection results. The cooperation between the slider 104 and the slide groove 103 can ensure the stability of the up and down movement of the fixed plate 107. The setting of the tool box 109 facilitates the storage of the detection tools, thereby ensuring the detection efficiency of the soil.

[0036] Furthermore, the multi-point detection assembly includes a puncture head 113 disposed at the lower end of the detection tube 110, the upper end of the puncture head 113 is detachably connected to the lower end of the detection tube 110, a straight rod 111 is welded to the middle of the upper end of the puncture head 113, a side of the straight rod 111 away from the column 102 is detachably mounted with a plurality of spectral sensors 112, the spectral sensors 112 are equidistantly distributed, a measuring window 114 is provided on the side of the detection tube 110 away from the servo motor 105, both sides of the measuring window 114 are provided with inclined surfaces 115, and the inclined surfaces 115 are inclined toward the inner wall of the detection tube 110. The spectral sensor 112 corresponds to the measuring window 114 one by one, a strip groove 116 is provided on the side of the fixed plate 107 close to the detection tube 110, an auxiliary rod 117 is provided on the side of the movable frame 101 away from the servo motor 105, the auxiliary rod 117 is fixedly connected to the column 102, the auxiliary rod 117 is movably connected to the strip groove 116, a pushing block 118 is fixedly installed on the lower end of the auxiliary rod 117, the side surface of the pushing block 118 is triangular, and the protruding end of the pushing block 118 is set to an arc surface, and a bracket 119 is welded on the side of the fixed plate 107 close to the detection tube 110.

[0037] In this embodiment, during the downward movement, the puncture head 113 on the detection tube 110 follows the movement, so that the puncture head 113 is first inserted into the soil, and then the servo motor 105 is continued to be controlled to rotate, thereby driving the detection tube 110 to penetrate into the soil, so that the detection tube 110 reaches a set depth, and then the multiple spectral sensors 112 arranged inside the detection tube 110 detect soil points at different depths through the measuring window 114, thereby quickly detecting soil parameters at multiple points at different depths, and avoiding soil mixing caused by soil collapse during soil drilling, thereby further improving the detection accuracy of soil parameters, and at the same time, through the inclined surfaces 115 on both sides of the measuring window 114, it is more convenient for the rubber block 207 to rotate in or out of the measuring window 114, and through the setting of the strip groove 116, it is ensured that the fixing plate 107 will not interfere with the auxiliary rod 117 during the movement.

[0038] During detection, the servo motor 105 is turned on, and the servo motor 105 drives the screw rod 106 to rotate forward. The screw rod 106 cooperates with the screw rod sleeve 108 to drive the fixing plate 107 to move downward, so that the fixing plate 107 drives the two detection tubes 110 on the right to move with it, so that the detection tubes 110 can be inserted into the soil, so as to achieve multi-point detection effect in two directions of the soil in the detection area, and avoid the trouble of drilling and detecting the soil at different points, thereby improving the detection efficiency of the soil. When the detection tube 110 moves downward, the puncture head 113 on the detection tube 110 Following the movement, the piercing head 113 is first inserted into the soil, and then the servo motor 105 is continuously controlled to rotate, thereby driving the detection tube 110 to penetrate into the soil, so that the detection tube 110 reaches a set depth, and then the soil points at different depths are detected through the measuring window 114 by multiple spectral sensors 112 arranged inside the detection tube 110, thereby quickly detecting the soil parameters at different depths of multiple points, and avoiding the soil mixing caused by soil collapse during the soil drilling process, thereby further improving the detection accuracy of soil parameters.

[0039] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a deep multi-point soil parameter rapid detection device, which solves the problem that the measurement window 114 cannot be blocked and the measurement is switched, resulting in the measurement window 114 not being blocked during the deep soil penetration process, causing the soil to enter the detection tube 110. The switching component includes a ratchet ring 202 arranged above the glass tube 201, a ratchet rod 204 is arranged on the inner side of the ratchet ring 202, and the ratchet end of the ratchet rod 204 is meshed with the inner tooth groove of the ratchet ring 202, and a fixing rod 203 is arranged above the ratchet ring 202. Smooth strips 205 are arranged on the front and rear sides of the fixing rod 203, and limit plates 208 are arranged on the front and rear ends of the strip groove 116. The lower end of the limit plate 208 is fixedly connected to the upper end of the fixing plate 107, and the fixing rod 203 is arranged between the limit plate 208 and the auxiliary rod 117 The upper end of the fixing rod 203 away from the auxiliary rod 117 is rotatably connected to the lower end of the bracket 119 through a bearing. A plurality of rubber blocks 207 are arranged on the surface of the glass cylinder 201. The rubber blocks 207 are distributed in a ring shape, and the rubber blocks 207 correspond to the measuring windows 114 one by one. The size of the rubber blocks 207 matches the size of the measuring window 114. The end of the ratchet rod 204 close to the auxiliary rod 117 passes through the middle of the fixing rod 203 and is movably connected to the fixing rod 203. The outer side wall of the end of the ratchet rod 204 close to the auxiliary rod 117 is sleeved with a first spring 206. The lower end of the first spring 206 is fixedly connected to the fixing rod 203, and the upper end of the first spring 206 is fixedly connected to the ratchet rod 204. A second spring 209 is fixedly installed on one side of the limiting plate 208 close to the fixing rod 203, and the other end of the second spring 209 is fixedly connected to the surface of the smooth strip 205.

[0040] In this embodiment, the rubber block 207 is fixedly connected to the glass tube 201 by gluing. The glass tube 201 is made of transparent glass. When the fixing plate 107 moves downward, the glass tube 201 inside the detection tube 110 moves accordingly, and the ratchet ring 202 on the glass tube 201 also moves accordingly. When the fixing plate 107 moves to the top of the pushing block 118, the fixing plate 107 continues to move downward. At this time, the pushing block 118 on the auxiliary rod 117 contacts the smooth strip 205 on the fixing rod 203. The pushing block 118 pushes the fixing rod 203 to deflect outward by 15 degrees, thereby driving the ratchet rod 204 on the fixing rod 203 to rotate accordingly, and at the same time squeezing the second spring 209, so that the ratchet rod 204 drives the ratchet ring 202 to rotate. The first spring 206 drives the pawl rod 204 to snap into the adjacent tooth groove. At this time, the fixed plate 107 no longer moves downward, and the ratchet ring 202 deflected by 15 degrees drives the glass tube 201 to rotate 15 degrees, so that the rubber block 207 blocked in the measuring window 114 is rotated out, and the light-transmitting part of the glass tube 201 is rotated to the measuring window 114, so that the spectral sensor 112 can detect the soil parameters through the measuring window 114, thereby realizing the linkage to realize that the rubber block 207 blocked in the measuring window 114 is moved out when the detection tube 110 is in place. The rubber block 207 is rotated out, thereby improving the soil detection efficiency. In addition, due to the existence of the rubber block 207, it can be avoided that the soil enters the detection tube 110 during the downward movement of the detection tube 110. At the same time, when the rubber block 207 is rotated out, the detection tube 110 is switched from the closed state to the detection state, further improving the soil detection effect. After the detection is completed, the fixed plate 107 is controlled to move upward and reset. At this time, the smooth strip 205 on the fixed rod 203 will contact the pushing block 118 again, and then drive the fixed rod 203 to deflect 15 degrees again, thereby realizing the deflection of the glass tube 201 again, so that the rubber block 207 of the adjacent group is rotated into the measuring window 114, so that the rubber block 207 blocks the measuring window 114, avoiding the detection. During the separation of the measuring tube 110 from the soil, the glass tube 201 is in direct contact with the soil, causing the soil to scratch the glass tube 201, thereby avoiding the influence of the damaged glass tube 201 on the detection of the spectral sensor 112, thereby ensuring the accuracy of soil parameters and reducing the maintenance frequency of the glass tube 201. At the same time, during the process of the rubber block 207 being rotated into the measuring window 114, the rubber block 207 can also push out the soil entering the edge of the measuring window 114 due to soil collapse during the detection of the spectral sensor 112, thereby reducing the soil parameter error caused by the next soil detection. Due to the design of the inclined surfaces 115 on both sides of the measuring window 114, it is convenient for the rubber block 207 to be smoothly rotated in or out.

[0041] Specifically, the cleaning assembly includes a fixed ring 210 arranged on the outside of the detection tube 110, the fixed ring 210 is fixedly connected to the lower end of the movable frame 101, and the two fixed rings 210 are symmetrically arranged, the fixed rings 210 correspond one to one with the detection tube 110, and a rubber scraper ring 211 is detachably installed on the inner side of the fixed ring 210, and the inner wall of the rubber scraper ring 211 fits with the outer wall of the detection tube 110.

[0042] In this embodiment, after the detection is completed, the fixed plate 107 is controlled to move upward, and the fixed plate 107 will drive the detection tube 110 to separate from the soil. At this time, the rubber scraper ring 211 inside the fixed ring 210 will scrape off the soil sticking to the surface of the detection tube 110, thereby saving the trouble of the staff to clean the detection tube 110.

[0043] The rest of the structure is the same as that of Example 1.

[0044] When in use, during the downward movement of the fixing plate 107, the glass tube 201 inside the detection tube 110 moves accordingly, and at the same time, the ratchet ring 202 on the glass tube 201 also moves accordingly. When the fixing plate 107 moves to the top of the pushing block 118, the fixing plate 107 continues to move downward. At this time, the pushing block 118 on the auxiliary rod 117 contacts the smooth strip 205 on the fixing rod 203. The pushing block 118 pushes the fixing rod 203 to deflect outward by 15 degrees, thereby driving the ratchet rod 204 on the fixing rod 203 to rotate accordingly, and at the same time squeezing the second spring 209, so that the ratchet rod 204 drives the ratchet ring 202 to rotate one tooth groove. When the pushing block 118 passes the fixing rod 203, the driving force disappears at this time. With the spring resilience, the second spring 209 The fixing rod 203 is driven to reset, and at the same time, the first spring 206 drives the pawl rod 204 to be stuck in the adjacent tooth groove. At this time, the fixing plate 107 no longer moves downward, and at the same time, the ratchet ring 202 deflected by 15 degrees drives the glass tube 201 to rotate 15 degrees, so that the rubber block 207 blocked in the measuring window 114 is rotated out, and at the same time, the light-transmitting part of the glass tube 201 is rotated to the measuring window 114, so that it is convenient for the spectral sensor 112 to detect soil parameters through the measuring window 114, so that the rubber block 207 blocked in the measuring window 114 is rotated out while the detection tube 110 is in place, thereby improving the soil detection efficiency. In addition, due to the existence of the rubber block 207, it can be avoided that the soil enters the detection tube 110 during the downward movement of the detection tube 110. The situation inside the detection tube 110 is detected. At the same time, when the rubber block 207 is rotated out, the detection tube 110 is switched from the closed state to the detection state, which further improves the soil detection effect. After the detection is completed, the fixed plate 107 is controlled to move upward and reset. At this time, the smooth strip 205 on the fixed rod 203 will contact the pushing block 118 again, and then drive the fixed rod 203 to deflect 15 degrees again, so that the glass tube 201 is deflected again, so that the rubber block 207 of the adjacent group is rotated into the measuring window 114, so that the rubber block 207 blocks the measuring window 114, and avoids the situation that the glass tube 201 directly contacts the soil during the separation process of the detection tube 110 and the soil, causing the soil to scratch the glass tube 201, thereby avoiding the damage of the glass tube 201. 01 affects the detection of the spectral sensor 112, thereby ensuring the accuracy of soil parameters and reducing the maintenance frequency of the glass tube 201. At the same time, when the rubber block 207 moves into the measuring window 114, the rubber block 207 can also push out the soil that enters the edge of the measuring window 114 due to soil collapse during the detection process of the spectral sensor 112, thereby reducing the soil parameter error caused by the next soil detection. After the detection is completed, the fixed plate 107 is controlled to move upward, and the fixed plate 107 will drive the detection tube 110 to separate from the soil. At this time, the rubber scraper ring 211 inside the fixed ring 210 will scrape off the soil sticking to the surface of the detection tube 110, thereby saving the trouble of the staff to clean the detection tube 110.
