Description

Technical Field

[0001] The invention relates to the technical field of forestry breeding soil quality detection, in particular to a soil quality analyzer used for forestry breeding. Background Art

[0002] Tree breeding refers to the technology of genetically improving trees for predetermined purposes. In tree breeding work, introduction has the longest history. The mechanism of this technology is to utilize the variation and differentiation of tree populations under natural or human influences to select, separate and breed groups or individuals that meet the purpose. The main approaches include introduction and domestication (see tree introduction), provenance testing, selective breeding, hybrid breeding, haploid and polyploid breeding (see ploidy breeding), radiation mutagenesis (see mutagenesis breeding), etc.

[0003] When forestry is breeding, it is necessary to test the soil nutrients of the breeding land, which plays a very important role in forestry breeding. In the existing technology, when testing the soil required for breeding, the soil is generally brought back to the laboratory for shade drying and sample preparation, and then chemical methods are used for testing. Although the detection accuracy is high, the detection process is complicated. When conducting soil analysis and testing at different locations or at different depths in the same location, the labor intensity is high, the detection is time-consuming, and the work efficiency is low. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a soil analyzer for forestry breeding, which has the advantages that a lifting device can drive the lifting of a tunneling bucket through a base, and a rotating device can control the rotation of the tunneling bucket. When taking soil samples, the tunneling bucket can be controlled to descend and to rotate at the same time so that the tunneling bucket can enter the soil to be tested. When the tunneling bucket reaches a specified depth, an angle calibration component is first arranged to cooperate with the rotating device to calibrate the position of the tunneling bucket so that the axis of the sampling hole is parallel to the axis of the extension port, and then the tunneling bucket is lifted to a certain depth. The component controls the installation barrel to move downward relative to the excavation barrel so that the axis of the extension port coincides with the axis of the sampling hole. Finally, the sampling component is extended from the extension port and the sampling barrel through the push-pull component to sample soil at different heights. The soil in the sampling component can be transported to the screening device through the set hose auger. The screening device will screen the impurities in the sampled soil. The sampled soil after screening can be used for soil testing, so that soil sampling and screening are integrated operations. After the soil sampling is completed, the soil can be screened at the sampling site and a preliminary analysis of the soil can be performed, thereby shortening the detection cycle and reducing the detection cost.

[0005] The above object of the present invention is achieved through the following technical solutions:

The lower end of the mounting cylinder is connected to an angle calibration component, the upper end of the mounting cylinder is connected to the base through a lifting component, a vertically arranged base plate is provided in the mounting cylinder, a push-pull component is provided between the vertically arranged side of the base plate and the mounting cylinder, a plurality of sampling components are fixedly connected to the side of the base plate close to the push-pull component, a side wall of the mounting cylinder is provided with an extension port corresponding to the sampling component, the sampling component can be extended from the extension port, a hose auger is connected to the upper side of the sampling component, the upper end of the hose auger is connected to the top of the screening device through a support frame, and the support frame is fixedly connected to the base.

[0007] By adopting the above technical scheme, the lifting device can drive the excavation bucket to rise and fall through the base, and the rotating device can control the excavation bucket to rotate. When soil sampling is performed, the excavation bucket can be controlled to descend and the excavation bucket can be controlled to rotate so that the excavation bucket can enter the soil to be tested. When the excavation bucket reaches the specified depth, the angle calibration component is first arranged to cooperate with the rotating device to calibrate the position of the excavation bucket so that the axis of the sampling hole is parallel to the axis of the extension port, and then the installation tube is controlled to move downward relative to the excavation bucket through the lifting component so that the axis of the extension port coincides with the axis of the sampling hole. Finally, the sampling component is extended from the extension port and the sampling tube through the push-pull component to sample soil at different heights. The soil in the sampling component can be transported to the screening device through the hose auger, and the screening device will screen the impurities in the sampled soil. The sampled soil after screening can be tested, so that soil sampling and screening are integrated. After the soil sampling is completed, the soil can be screened and preliminarily analyzed at the sampling site, thereby shortening the detection cycle and reducing the detection cost.

[0008] In a preferred example, the present invention can be further configured as follows: the screening device includes a driving box, the driving box is fixedly connected to the workbench, the screening box is slidably connected to the upper side of the driving box, the driving box is rotatably connected to a driving shaft, the axis of the driving shaft is parallel to the sliding direction of the screening box, the driving shaft sleeve is provided with a first I-shaped wheel shaft and is hinged thereto, the bottom of the screening box is fixedly connected to a transmission rod, the lower end of the transmission rod is spherically arranged, the lower end of the transmission rod is located on the inner side of the first I-shaped wheel shaft, one end of the first I-shaped wheel shaft is provided with an adjustment assembly, one end of the driving shaft passes through the driving box and is fixedly connected to a first motor, and the first motor is fixedly connected to the driving box.

[0009] By adopting the above technical scheme, the arranged adjustment component can drive the first I-wheel shaft to rotate around the hinge between itself and the driving shaft. When the axis of the first I-wheel shaft coincides with the axis of the driving shaft, the rotation of the first motor will not drive the transmission rod to swing. When the angle between the axis of the first I-wheel shaft and the axis of the driving shaft is an acute angle, the rotation of the driving shaft will drive the inclined first I-wheel shaft to rotate around the axis of the driving shaft, so that the transmission rod located in the first I-wheel shaft will reciprocate in the axial direction of the driving shaft under the action of the first I-wheel shaft, and the transmission rod will transmit this reciprocating motion to the screening box, so that the screening box vibrates. The vibration of the screening box can screen the sampled soil. By controlling the change of the angle between the axis of the first I-wheel shaft and the axis of the driving shaft, the swing amplitude of the transmission rod can be changed, thereby changing the vibration amplitude of the screening box, and then the vibration amplitude of the screening box can be adjusted according to the size of the sampled soil particles and the situation of other impurities contained therein, thereby improving the working efficiency of screening the sampled soil, and at the same time improving the screening index of the screening box, making the test data more accurate.

[0010] In a preferred example, the present invention can be further configured as follows: the adjustment component includes a second I-wheel axle, the second I-wheel axle is sleeved on the drive shaft and slidably connected thereto, a pull rod is provided between the second I-wheel axle and the first I-wheel axle, both ends of the pull rod are respectively hinged to the first I-wheel axle and the second I-wheel axle, a rotating block is provided on the inner side of the second I-wheel axle, one end of the rotating block is rotatably connected to one end of a telescopic rod, and the other end of the telescopic rod is fixedly connected to the drive box.

[0011] By adopting the above technical solution, the rotating block can be moved along the extension and retraction direction of the telescopic rod by controlling the extension and retraction of the telescopic rod. The movement of the rotating block will drive the second I-wheel axle to slide on the driving shaft. The sliding of the second I-wheel axle will drive the pull rod to move. The movement of the pull rod will cause the first I-wheel axle to rotate around the hinge between itself and the transmission shaft, thereby adjusting the amplitude of the screening box.

[0012] In a preferred example, the present invention can be further configured as follows: the screening box includes a box body, the box body is slidably connected to the driving box, the inner side of the screening box is divided into a plurality of screening chambers by a plurality of partitions, a first screening plate and a second screening plate are fixedly connected from top to bottom in the screening chamber, the first screening plate and the second screening plate are both inclined to one side, a plurality of storage boxes are inserted into the side wall of the lower part of the box body, and the storage boxes correspond one to one to the screening chambers.

[0013] By adopting the above technical scheme, the sampled soil can be screened multiple times by the first screening plate and the second screening plate, so that impurities in the sampled soil can be filtered, the purity of the sampled soil is improved, and larger soil particles can be filtered out. The filtered sampled soil can fall into the storage box, and the inclined first screening plate and the second screening plate can increase the contact area with the sampled soil, so that the sampled soil can be screened more fully. At the same time, the filtered material will be deposited at the low position of the first screening plate and the second screening plate, thereby effectively avoiding the problem of the first screening plate and the second screening plate being completely blocked due to excessive impurities filtered, so that the user only needs to remove the impurities regularly.

[0014] In a preferred example, the present invention can be further configured as follows: a test tube placement tray is fixedly connected to one side of the vertically arranged box body, and a plurality of test tube placement cavities are opened on the upper side of the test tube placement tray.

[0015] By adopting the above technical scheme, the test tube placement cavity provided can be used to hold the test tube, and the box can be shaken by controlling the rotation of the first motor, so that the solution in the test tube can be fully shaken without manual shaking, and the solution is shaken by the driving force of the screening device, so that the screening device can serve multiple purposes, effectively improving the practicability of the device and reducing the production cost.

[0016] In a preferred example, the present invention can be further configured as follows: the sampling component includes a sampling barrel, one end of the sampling barrel is fixedly connected to the base plate, the other end of the sampling barrel is opened, a baffle is fixedly connected inside the sampling barrel, a second motor is fixedly connected to the side of the baffle close to the base plate, the output shaft of the second motor passes through the baffle and is fixedly connected to a rotating shaft, the output shaft is rotatably connected to the baffle, a spiral blade is fixedly connected to the side wall of the rotating shaft, a discharge port is provided on the upper side wall of the sampling barrel, and the hose auger is connected to the discharge port.

[0017] By adopting the above technical solution, the rotation of the second motor can be controlled to drive the rotation of the rotating shaft, and the spiral blades on the rotating shaft also rotate therewith. When the sampling barrel penetrates deeper into the soil, the rotation of the spiral blades can transport the soil at the open end of the sampling barrel to the interior of the sampling barrel. The set hose auger can transport the soil inside the sampling barrel to the corresponding screening chamber, and the spiral blades also have a certain crushing effect on the soil in the process of penetrating deeper into the soil, thereby facilitating the subsequent transportation and subsequent detection of the soil.

[0018] In a preferred example, the present invention can be further configured as follows: the lifting assembly includes a fixed seat, the fixed seat is sleeved on the mounting tube and fixedly connected thereto, a plurality of first telescopic cylinders are fixedly connected to the lower side of the fixed seat, and the lower ends of the first telescopic cylinders are fixedly connected to the base.

[0019] By adopting the above technical solution, controlling the extension and retraction of the first telescopic cylinder can drive the installation tube to move up and down relative to the excavation barrel, thereby facilitating the control of the vertical position of the sampling tube and the sampling hole, thereby facilitating the control of the sampling tube for sampling.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. The lifting device can drive the excavation bucket to rise and fall through the base, and the rotating device can control the excavation bucket to rotate. When soil sampling is performed, the excavation bucket can be controlled to descend and simultaneously controlled to rotate so that the excavation bucket can enter the soil to be tested. When the excavation bucket reaches the specified depth, the angle calibration component is first arranged to cooperate with the rotating device to calibrate the position of the excavation bucket so that the axis of the sampling hole is parallel to the axis of the extension port. Then, the lifting component is used to control the installation barrel to move downward relative to the excavation bucket so that the axis of the extension port coincides with the axis of the sampling hole. Finally, the sampling component is extended from the extension port and the sampling barrel through the push-pull component to sample soil at different heights. The soil in the sampling component can be transported to the screening device through the hose auger. The screening device will screen the impurities in the sampled soil. The sampled soil after screening can be tested for soil quality, so that soil sampling and screening are integrated. After the soil sampling is completed, the soil can be screened and preliminarily analyzed at the sampling site, thereby shortening the detection cycle and reducing the detection cost.

[0022] 2. The sampled soil can be screened multiple times by the first screening plate and the second screening plate, so that the impurities in the sampled soil can be filtered out, the purity of the sampled soil can be improved, and the larger soil particles can be filtered out. The filtered sampled soil can fall into the storage box, and the inclined first screening plate and the second screening plate can increase the contact area with the sampled soil, so that the sampled soil can be screened more fully. At the same time, the filtered material will be deposited at the low position of the first screening plate and the second screening plate, thereby effectively avoiding the problem of the first screening plate and the second screening plate being completely blocked due to excessive filtered impurities, so that the user only needs to remove the impurities regularly.

[0023] 3. The test tube placement cavity provided can be used to hold test tubes. By controlling the rotation of the first motor, the box can be shaken, so that the solution in the test tube can be fully shaken without manual shaking.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, a soil quality analyzer for forestry breeding disclosed in the present invention comprises a base 1 and a workbench 2. A storage battery is arranged inside the workbench 2. The storage battery provides power to various electronic devices. The workbench 2 is fixedly connected to the upper side of the base 1. A screening device 3 is fixedly connected to the upper side of the workbench 2. A lifting device 4 is fixedly connected to the upper side of the base 1. The lifting device 4 comprises a threaded rod 41. The lower end of the threaded rod 41 is rotatably connected to the base 1. The upper end of the threaded rod 41 is rotatably connected to a mounting plate 42. Both ends of the lower side of the mounting plate 42 are fixedly connected to guide rods. The lower end of the guide rod 43 is fixedly connected to the base 1, the upper end of the mounting plate 42 is fixedly connected to the fourth motor 44, the upper end of the threaded rod 41 passes through the mounting plate 42 and is fixedly connected to the output shaft of the fourth motor 44, the threaded rod 41 is sleeved with a sliding block 45 and is threadedly connected thereto, and the sliding block 45 is sleeved on the two guide rods 43, and the guide rods 43 are slidably connected to the sliding block 45, wherein the lifting device 4 can also be replaced by other lifting mechanisms, and the lifting device 4 selected in the present invention has the outstanding advantage of being able to accurately control the height of the sliding block 45. The sliding block 45 can be moved up and down by controlling the rotation of the fourth motor 44.

[0033] like Figure 1 and Figure 3As shown, the sliding block 45 is vertically arranged with one side fixedly connected to the base 5, a tunneling bucket 6 is inserted through the upper side of the base 5 and is rotatably connected thereto, the tunneling bucket 6 is connected to a rotating device 7, and a plurality of sampling holes 8 are opened in the side wall of the tunneling bucket 6 in the vertical direction. In this embodiment, the number of sampling holes 8 is three, and the lower end of the tunneling bucket 6 is conical. At the same time, a spiral feed sheet is also arranged on the outer side of the tunneling bucket 6. The arranged feed sheet helps the tunneling bucket 6 to penetrate into the ground, and at the same time, the soil during tunneling can be transported to the upper side of the ground. A sampling device 9 is arranged on the inner side of the tunneling bucket 6, as shown in FIG. Figure 3 As shown, the sampling device 9 includes a mounting tube 91 , the outer wall of the mounting tube 91 is arranged to fit the inner wall of the excavation bucket 6 , the lower end of the mounting tube 91 is connected to an angle calibration component 92 , and the upper end of the mounting tube 91 is connected to the base 5 via a lifting component 93 .

[0034] like Figure 1 and Figure 2 As shown, further, the lifting assembly 93 includes a fixed seat 931, which is sleeved on the mounting barrel 91 and fixedly connected thereto, and a plurality of first telescopic cylinders 932 are fixedly connected to the lower side of the fixed seat 931. Preferably, there are four first telescopic cylinders 932, which are located at the four corners of the lower side of the fixed seat 931, and the lower ends of the first telescopic cylinders 932 are fixedly connected to the base 5. By controlling the expansion and contraction of the first telescopic cylinders 932, the mounting barrel 91 can be driven to move up and down relative to the excavation barrel 6. Figure 3 As shown, a vertically arranged base plate 94 is provided in the mounting cylinder 91, and a push-pull component 95 is provided between the vertically arranged side of the base plate 94 and the mounting cylinder 91. Preferably, the push-pull component 95 is a plurality of second telescopic cylinders, and the two ends of the second telescopic cylinders are respectively fixedly connected to the mounting cylinder 91 and the base plate 94. Other devices with telescopic structures can also be used to replace the second telescopic cylinders. A plurality of sampling assemblies 96 are fixedly connected to one side of the base plate 94 close to the push-pull component 95. The number of sampling assemblies 96 and the number of sampling holes 8 correspond one to one. The side wall of the mounting cylinder 91 is provided with an extension port corresponding to the sampling assembly 96, and the sampling assembly 96 can be extended from the extension port. A hose auger 97 is connected to the upper side of the sampling assembly 96. The upper end of the hose auger 97 is connected to the top of the screening device 3 through a support frame 98, and the support frame 98 is fixedly connected to the base 1.

[0035] like Figure 1 and Figure 3As shown, when soil sampling is carried out, the sampling hole 8 is in a closed state, that is, the protruding hole on the side wall of the mounting tube 91 is misaligned with the sampling hole 8 on the excavation bucket 6. At this time, the side wall of the mounting tube 91 closes the sampling tube 961, thereby preventing external soil from entering the sampling device 9 when the excavation bucket 6 moves downward, thereby avoiding mixing of soils at different heights, thereby ensuring the accuracy of data during soil testing. By controlling the excavation bucket 6 to descend and controlling the excavation bucket 6 to rotate, the excavation bucket 6 can be made to enter the soil to be tested. When the excavation bucket 6 reaches the specified depth, the angle calibration component 92 is first set to cooperate with the rotating device 7 to calibrate the position of the excavation bucket 6, so that the axis of the sampling hole 8 is parallel to the axis of the extension port, and then the lifting component 93 is used to control the installation tube 91 to move downward relative to the excavation bucket 6 so that the axis of the extension port coincides with the axis of the sampling hole 8. Finally, the sampling component 96 is extended from the extension port and the sampling tube 961 by the push-pull component 95 to sample soil at different heights. The soil in the sampling component 96 can be transported to the screening device 3 through the set hose auger 97. The screening device 3 will screen the impurities in the sampled soil. The sampled soil after screening can be used for soil testing, so that soil sampling and screening are integrated operations. After the soil sampling is completed, the soil can be screened and preliminarily analyzed at the sampling site, thereby shortening the detection cycle and reducing the detection cost.

[0036] like Figure 1 and Figure 2 As shown, the lifting assembly 93 includes a fixed seat 931, which is sleeved on the mounting tube 91 and fixedly connected thereto. A plurality of first telescopic cylinders 932 are fixedly connected to the lower side of the fixed seat 931. The lower ends of the first telescopic cylinders 932 are fixedly connected to the base 5. The first telescopic cylinders 932 are preferably hydraulic cylinders, which can drive the mounting tube 91 to move up and down by controlling the contraction of the hydraulic cylinders.

[0037] like Figure 1 and Figure 2As shown, the rotating device 7 includes a driven gear 71, which is sleeved on the excavation bucket 6 and fixedly connected thereto, and the driven gear 71 is meshed with a driving gear 72. A third motor 73 is provided at the upper end of the driving gear 72, and the driving gear 72 is fixedly connected to the output shaft of the third motor 73. The third motor 73 is fixedly connected to the base 5 via a connecting seat 74. Furthermore, the angle calibration assembly 92 includes an angle sensor 921, which is preferably a WOA-A angle sensor 921. The angle sensor 921 is fixedly connected to the lower end of the mounting tube 91, and the detection end of the angle sensor 921 is fixedly connected to a spline shaft 922. The spline shaft 922 is plugged into the bottom of the excavation barrel 6 and is slidably connected thereto. When the mounting tube 91 moves up and down relative to the excavation barrel 6, the spline shaft 922 will not fall off the excavation barrel 6. When the excavation barrel 6 rotates, the spline shaft 922 also rotates therewith. A controller 923 is also fixedly connected to one side of the drive box 31, and the angle sensor 921 and the third motor 73 are both electrically connected to the controller 923. The initial set angle value of the angle sensor 921 is that the axis of the sampling hole 8 is parallel to the axis of the extension port. When the excavation bucket 6 rotates relative to the mounting barrel 91, that is, when the excavation bucket 6 reaches the specified depth and needs to be sampled, the excavation bucket 6 stops rotating. The angle sensor 921 detects the rotation angle of the excavation bucket 6 and then transmits the detected data to the controller 923. After receiving the detection signal, the controller 923 feeds back the third motor 73. After receiving the feedback signal, the third motor 73 rotates. The rotation of the third motor 73 can drive the driving gear 72 to rotate. The rotation of the driving gear 72 can drive the driven gear 71 to rotate. The rotation of the driven gear 71 can drive the excavation bucket 6 to rotate, so that the axis of the sampling hole 8 on the excavation bucket 6 and the axis of the extension port on the mounting barrel 91 can be parallel.

[0038] like Figure 1 and Figure 4As shown, the screening device 3 includes a driving box 31, which is fixedly connected to the workbench 2. A screening box 32 is slidably connected to the upper side of the driving box 31. The driving box 31 is rotatably connected to a driving shaft 33. The axis of the driving shaft 33 is parallel to the sliding direction of the screening box 32. The driving shaft 33 is sleeved with a first I-shaped wheel shaft 34 and is hinged thereto. A transmission rod 35 is fixedly connected to the bottom of the screening box 32. The lower end of the transmission rod 35 is spherically arranged, and the lower end of the transmission rod 35 is located on the inner side of the first I-shaped wheel shaft 34. An adjusting component 36 is provided at one end of the first I-shaped wheel shaft 34. The arranged adjusting component 36 can drive the first I-shaped wheel shaft 34 to rotate around the hinge between itself and the driving shaft 33. One end of the driving shaft 33 passes through the driving box 31 and is fixedly connected to a first motor 37. The first motor 37 is fixedly connected to the driving box 31. When the axis of the first I-wheel shaft 34 coincides with the axis of the drive shaft 33, the rotation of the first motor 37 will not cause the transmission rod 35 to swing. When the angle between the axis of the first I-wheel shaft 34 and the axis of the drive shaft 33 is an acute angle, the rotation of the drive shaft 33 will drive the inclined first I-wheel shaft 34 to rotate around the axis of the drive shaft 33, so that the transmission rod 35 located in the first I-wheel shaft 34 will reciprocate in the axial direction of the transmission shaft under the action of the first I-wheel shaft 34, and the transmission rod 35 will transmit this reciprocating motion to the screening The box 32 is moved by the vibration of the screening box 32, so that the screening box 32 vibrates. The vibration of the screening box 32 can screen the sampled soil. The swing amplitude of the transmission rod 35 can be changed by controlling the change of the angle between the axis of the first I-shaped wheel shaft 34 and the axis of the driving shaft 33, so that the vibration amplitude of the screening box 32 can be changed. Then, the vibration amplitude of the screening box 32 can be adjusted according to the size of the sampled soil particles and the situation of other impurities contained therein, thereby improving the working efficiency of screening the sampled soil, and at the same time improving the screening index of the screening box 32, so that the test data is more accurate.

[0039] like Figure 4 As shown, the adjustment assembly 36 includes a second I-shaped wheel shaft 361, which is sleeved on the drive shaft 33 and slidably connected thereto, a pull rod 362 is provided between the second I-shaped wheel shaft 361 and the first I-shaped wheel shaft 34, and both ends of the pull rod 362 are respectively hinged to the first I-shaped wheel shaft 34 and the second I-shaped wheel shaft 361, and a rotating block 363 is provided on the inner side of the second I-shaped wheel shaft 361, one end of the rotating block 363 is rotatably connected to one end of a telescopic rod 364, and the other end of the telescopic rod 364 is fixedly connected to the drive box 31. Preferably, the telescopic rod 364 is an electric telescopic rod. By controlling the extension and retraction of the telescopic rod 364, the rotating block 363 can be moved along the extension and retraction direction of the telescopic rod 364. The movement of the rotating block 363 will drive the second I-wheel axle 361 to slide on the drive shaft 33. The sliding of the second I-wheel axle 361 will drive the pull rod 362 to move. The movement of the pull rod 362 will cause the first I-wheel axle 34 to rotate around the hinge between itself and the drive shaft, thereby adjusting the amplitude of the screening box 32.

[0040] like Figure 5 As shown, the screening box 32 includes a box body 321, which is slidably connected to the driving box 31. The inner side of the screening box 32 is divided into a plurality of screening chambers by a plurality of partitions 322. The first screening plate 323 and the second screening plate 324 are fixedly connected from top to bottom in the screening chamber. The first screening plate 323 and the second screening plate 324 are both inclined to one side. A plurality of storage boxes 325 are inserted into the side wall at the lower part of the box body 321. The storage boxes 325 correspond to the screening chambers one by one, and the storage boxes 325 are provided with locks, which can be fixed to the box body 321 by the locks, thereby preventing the storage boxes 325 from slipping off. The first screening plate 323 and the second screening plate 324 can screen the sampled soil multiple times, so that the impurities in the sampled soil can be filtered out, the purity of the sampled soil can be improved, and the larger soil particles can be filtered out. The filtered sampled soil can fall into the storage box 325, and the inclined first screening plate 323 and the second screening plate 324 can increase the contact area with the sampled soil, so that the sampled soil can be screened more fully. At the same time, the filtered material will be deposited at the low position of the first screening plate 323 and the second screening plate 324, thereby effectively avoiding the problem of the first screening plate 323 and the second screening plate 324 being completely blocked due to excessive filtered impurities, so that the user only needs to clear the impurities regularly.

[0041] Furthermore, a door body is provided on the side wall of the box body 321 at the upper part of the lower position of the first sieve plate 323 and the second sieve plate 324. The door body is not shown in the figure. The provided door body facilitates cleaning of impurities on the first sieve plate 323 and the second sieve plate 324.

[0042] like Figure 2 As shown, the box body 321 is vertically arranged with a test tube placement tray 10 fixedly connected to one side, and a plurality of test tube placement cavities 11 are opened on the upper side of the test tube placement tray 10. The test tube placement tray 10 is made of a transparent material, so that the internal conditions of the test tubes are easy to observe, and the upper end of the test tube placement cavity 11. The inner side of the upper end of the test tube placement cavity 11 is also fixedly connected with a rubber ring, and the rubber ring can achieve a good fixing effect on the test tube. After the sampling soil is screened, the screened sampling soil is taken out from the storage box 325, and then a certain amount of sampling soil is added to the test tube, followed by adding an appropriate amount of water, and shaking the test tube by hand for several times, and finally the test tube is placed in the test tube placement cavity 11. By controlling the rotation of the first motor 37, the box 321 can be vibrated, and the vibration time is 5 minutes, so that the solution in the test tube can be fully shaken without manual shaking. After the solution in the test tube is shaken, the obtained solution can be filtered through filter paper (if the filtrate is turbid, it needs to be filtered again). After the filtration is completed, the detection reagent can be added to the filtrate for detection.

[0043] During the oscillation process, the test tube uses the driving force of the screening device 3 to shake the solution evenly, so that the screening device 3 plays a multi-purpose role, effectively improving the practicality of the device and reducing the production cost. Before shaking the solution in the test tube, the amplitude of the box 321 needs to be adjusted to meet the amplitude of shaking the solution evenly.

[0044] like Figure 3 and Figure 6 As shown, the sampling assembly 96 includes a sampling barrel 961, one end of the sampling barrel 961 is fixedly connected to the base plate 94, and the other end of the sampling barrel 961 is opened. A baffle 962 is fixedly connected inside the sampling barrel 961, and a second motor 963 is fixedly connected to the side of the baffle 962 close to the base plate 94. The output shaft of the second motor 963 passes through the baffle 962 and is fixedly connected to a rotating shaft 964. The output shaft is rotatably connected to the baffle 962, and a spiral blade 965 is fixedly connected to the side wall of the rotating shaft 964. A discharge port is provided on the upper side wall of the sampling barrel 961, and a hose auger 97 is connected to the discharge port. By controlling the rotation of the second motor 963, the rotating shaft 964 can be driven to rotate, and the spiral blade 965 located on the rotating shaft 964 also rotates therewith. When the sampling barrel 961 goes deeper into the soil, the spiral blade 965 rotates to transport the soil at the open end of the sampling barrel 961 to the interior of the sampling barrel 961. The set hose auger 97 can transport the soil inside the sampling barrel 961 to the corresponding screening chamber, and the spiral blade 965 also has a certain crushing effect on the soil in the process of going deep into the soil, thereby facilitating the subsequent transportation and subsequent detection of the soil.

[0045] The third motor 73 and the fourth motor 44 mentioned in this embodiment are both servo motors, and the first motor 37 , the second motor 963 , the fourth motor 44 , the first telescopic cylinder 932 , the second telescopic cylinder, the electric telescopic rod 364 and the hose auger 97 are all electrically connected to the controller 923 .

[0046] The implementation principle of this embodiment is: when taking soil samples, the excavation bucket 6 can be lowered by controlling the rotation of the fourth motor 44, and the third motor 73 can be controlled to drive the excavation bucket 6 to rotate, so that the excavation bucket 6 can enter the soil to be detected. When the excavation bucket 6 reaches the specified depth, the angle sensor 921 is set to detect the rotation angle of the excavation bucket 6, and then transmit the detected data to the controller 923. After receiving the detection signal, the controller 923 feedbacks the third motor 73. After receiving the feedback signal, the third motor 73 rotates, so that the axis of the sampling hole 8 on the excavation bucket 6 is parallel to the axis of the extension port on the mounting tube 91, and then the first telescopic cylinder 932 is controlled to shrink. Thereby, the axis of the extension port coincides with the axis of the sampling hole 8, and finally, the sampling assembly 96 is extended from the extension port and the sampling tube 961 by controlling the contraction of the second telescopic cylinder, and the second motor 963 is controlled to rotate while the sampling tube 961 is extended, so that the rotating shaft 964 can rotate, and then the spiral blade 965 on the rotating shaft 964 can transport the soil to the interior of the sampling tube 961, and the set hose auger 97 can transport the soil inside the sampling tube 961 to the corresponding screening chamber, and finally, the set hose auger 97 can transport the soil in the sampling tube 961 to the screening device 3, and the screening device 3 will screen the impurities in the sampled soil, and the sampled soil after screening can be used for soil quality testing.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
