Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural soil sampling, in particular to an agricultural soil environment detection sampling device and a method thereof. Background Art
[0002] Agricultural soil, also known as cultivated soil, is formed on the basis of natural soil through human production activities such as tillage, fertilization, irrigation, and improvement, as well as the combined effects of natural factors. Examples include soil in cultivated land, orchards, and tea gardens. To ensure the stable development of agriculture, soil environmental testing and protection are receiving increasing attention. Since soil sampling is required before testing, replacing manual labor with instruments can reduce workload and improve safety. Currently, soil sampling devices for testing suffer from poor flexibility, low efficiency, unadjustable soil penetration depth, and inconvenience in use. Patents have been released to address these issues.
[0003] For example, Chinese patent CN211477701U discloses a sampling device for soil testing in an agricultural environment, comprising a base plate, a column, a buffer spring, a bearing plate, a turntable assembly, a driving mechanism, a soil outlet pipe, a crushing mechanism, a negative pressure device, a guide claw plate, and a rigid support assembly. The four corners of the upper end face of the base plate are each vertically provided with a column, a bearing plate is slidably passed through the upper portion of the column, and a buffer spring is padded on the lower portion of the bearing plate, which is sleeved on the column. The rigid support assembly of the present invention is configured so that when the soil outlet pipe is wound around the winding wheel of the turntable assembly, the magnetic attraction between the magnetic shafts is cut off. When the soil outlet pipe is extended vertically downward, the multiple magnetic shafts are attracted together, thereby increasing the rigidity of the soil outlet pipe and making it easier to extend into the soil.
[0004] Although the equipment in the above documents can grab the soil with a grabbing plate to facilitate sampling, it is not practical in actual use, such as: When sampling and testing agricultural soil, only soil 5 to 20 centimeters below the ground is needed, so manual excavation is easy. In addition, agricultural soil sampling requires the use of a five-point method, which involves sampling at five points and then mixing the five samples for testing. This operation is relatively complicated, and using the equipment in the document not only fails to improve efficiency but also delays the operation. In addition, there are still relatively small grass root fragments in the soil after sampling. Due to the mechanism of the grass roots themselves and their characteristics of promoting microorganisms, if the grass roots are not removed, the overall structure and nutrient data of the soil will be affected. The equipment in the document is obviously unable to achieve this complete sampling function. Therefore, an agricultural soil environment detection sampling device capable of improving sample sampling quality is now designed to solve such defects. Summary of the Invention

[0015] The present invention provides an agricultural soil environment detection sampling device and method. Compared with existing technologies, it has the following advantages: (1) The agricultural soil environment detection sampling device and method thereof, by combining the sedimentation drying mechanism and the sampling lifting mechanism, the arrangement of the two mechanisms can utilize the five-point arrangement of several samplers to sample five points at a time, and after the sampling is completed, the five soil samples can be crushed and mixed by utilizing the coordination between the structures, and after the mixing is completed, the fine grass roots in the soil are floated up and removed by sedimentation.

[0016] (2) The agricultural soil environment detection sampling device and method thereof are characterized by providing a sliding plate in the interior of the second sliding frame for use with the first sliding frame, and providing a sampler at the bottom of the sliding plate.

In the process, the continuously rotating convex top block will press the water-screening frame, so that the water-screening frame can vibrate up and down, allowing the soil to be in uniform contact with the warm air, thereby improving the drying efficiency and quality.
[0018] (4) The agricultural soil environment detection sampling device and method thereof are used by installing a rebound rod on the inner side of the first sliding frame and matching it with a hook plate and a vertical sliding frame. The arrangement of these structures can ensure that when the sliding plate does not squeeze the push-pull plate, the elastic force of the third spring can be used to drive the hook plate and the arc-shaped rotating block not to dock with the L-shaped pressure plate and the supporting plate, ensuring that when the cylinder is normally raised and lowered for sampling, no conflict will easily occur, thereby improving the stability of the equipment during operation.

[0024] The present invention also discloses a method for sampling agricultural soil environment detection, which specifically comprises the following steps: S1. Soil sampling: Push the sedimentation and drying mechanism 1 to the braking position, then start the cylinder 201 to push the sampler 204 down for sampling; S2. Crushing and settling: After sampling is completed, the soil sample is pushed into the crushing frame 113 by the pressing plate 209 for crushing, and falls into the inclined water storage tank 103 for settling; S3. Weeding and drying: remove the grass roots in the soil and dry the soil.
[0025] The above agricultural soil environment detection sampling method has the following more specific steps: S1. Soil sampling: Before use, push the sedimentation and drying mechanism 1 to the designated position, then fill the interior of the inclined water storage tank 103 with water, then manually remove the loose soil on the ground at the sampling position, and then start the cylinder 201 to push the second sliding frame 202 and the sliding plate 203 to descend synchronously. At this time, since the hook plate 214 and the L-shaped pressing plate 205 are staggered, the L-shaped pressing plate 205 will not contact the hook plate 214. After the sampler 204 descends to the bottom, several samplers 204 are pressed into the soil in a five-point manner. After the sampler 204 is completely immersed in the soil, start the cylinder 201 again to drive the second sliding frame 202, the sliding plate 203 and the sampler 204 to rise. At this time, the sampler 204 rises with the soil sample inside. After the sampler 204 is completely risen and reset, go to step S2; S2, crushing and settling: after the sliding plate 203 rises and resets, pull the sliding plate 203 by hand to move the sliding plate 203 from the second sliding frame 202 to the inner side of the first sliding frame 119, and then continue to push until the sliding plate 203 is completely moved to the left side of the inner cavity of the first sliding frame 119. At the same time, the sliding plate 203 will press the push-pull plate 215 to push the vertical sliding frame 213 to move left as a whole. At this time, the arc-shaped rotating block 218 is located just above the supporting plate 111, and the hook plate 214 is located just below the L-shaped pressing plate 205. At the same time, the sliding plate 203 uses the damping between it and the first sliding frame 119 to fix the push-pull plate 215. Then the cylinder 201 continues to start and push the second sliding frame 202 to descend again. At this time, the L-shaped pressing plate 205 contacts the hook plate 214 and presses the hook plate 214 down. The top plate 207 also drives the pressing plate 209 to synchronously descend with the vertical sliding frame 213 and the resistance rotating frame 217. During the descent of the pressing plate 209, the inner side of the sampler 204 will be inserted to squeeze out the soil, and then the soil sample falls into the inner side of the crushing frame 113. At this time, the motor 116 is started and the engagement of the gear plate 115 drives the two crushing rollers 117 to rotate synchronously. Then the crushing rollers 117 crush the soil sample, and the crushed soil falls into the interior of the inclined water storage tank 103, and then enters the interior of the water screening frame 109 through the inclined surface for standing. At this time, the buoyancy of the water is used to float the grass roots in the crushed soil sample. At this time, the I-shaped top plate 207 drops to the bottom, and at the same time, the arc-shaped rotating block 218 contacts the supporting plate 111 to flip and is located at the bottom of the supporting plate 111, and then goes to step S3; S3, weeding and drying: after the static state is completed, the cylinder 201 is started to drive the L-shaped pressure plate 205 to rise. At this time, the L-shaped pressure plate 205 is no longer pressed, and then the second spring 208 uses the elastic force to push the I-shaped top plate 207, the pressure plate 209, the vertical sliding frame 213 and the blocking rotating frame 217 to rise. At this time, the arc-shaped rotating block 218 lifts the supporting plate 111 and drives the water blocking frame 106 to rise under the limit of the L-shaped slider 105. The rise of the water blocking frame 106 uses the lifting rod 108 to pull the water sieve. The mesh frame 109 rises slowly and synchronously, and after the water blocking frame 106 rises and no longer blocks the concave opening 112, the water inside the inclined water tank 103 drives the grass roots floating on the top to flow out from the concave opening 112, and then the water screening mesh frame 109 continues to rise and completely falls off from the inclined water tank 103 and is located on the left side of the dryer 120. At this time, the cylinder 201 rises to the top and stops, and then the dryer 120 starts to blow out warm air to dry the soil inside the water screening mesh frame 109, and the soil is dried by rotating the rotating rod 114. The rotation drives the convex top block 118 to rotate, and the rotation of the convex top block 118 will continuously touch the water screening frame 109, so that the water screening frame 109 will continuously vibrate up and down under the elastic force of the first spring 110 to dry. After the drying is completed, the dryer 120 and the motor 116 are turned off, and then the water blocking frame 106 is supported by hand to pull up, so that the L-shaped slider 105 is separated from the guide slide frame 104, and then the pressing plate 209 and the water blocking frame 106 are taken out, and the soil sample inside is collected, and the sliding plate is moved downwards. 203 is pulled right to the inside of the second sliding frame 202. At this time, the push-pull plate 215 is no longer pressed and the elastic force of the third spring 216 is used to drive the resistance rotating frame 217 and the hook plate 214 to move right as a whole. At this time, the arc-shaped rotating block 218 and the hook plate 214 are not directly opposite to the supporting plate 111 and the L-shaped pressure plate 205 respectively. After the soil is taken out, the L-shaped slider 105 is connected to the guide sliding frame 104 to re-place the water screening frame 109 and the water blocking frame 106 into the concave opening 112.
