TECHNICAL FIELD

[0001] The application belongs to the technical field of soil sampling and detection, and particularly relates to a greenhouse soil sampling and detection device. BACKGROUND

[0002] Soil detection, as a key means for mastering the soil environment quality, aims to prevent soil pollution hazards and is realized by dynamically analyzing and measuring the degree of soil pollution and its change trend. The monitoring process usually covers the aspects of preparation, point distribution, sampling, sample preparation, analysis and testing, and evaluation.

[0003] A patent with the publication number CN109030078A discloses a soil sampler, which comprises a waist-shaped hole formed in a handle towards a pull rod, a moving rod arranged in the waist-shaped hole, a wire groove arranged on the outer wall of the annular flapper, a pull rope fixedly connected to the end of the moving rod away from the sampling cylinder, and the end of the pull rope away from the moving rod is fixedly connected with the groove bottom of the wire groove; the end of the moving rod away from the handle is respectively provided with a sleeve, the end of the sleeve close to the moving rod is provided with a moving groove for the sliding of the moving rod, the end of the moving rod away from the handle outwardly extends a resisting block, the opening of the moving groove inwardly extends a limiting block for resisting the block, the end of the sleeve away from the moving rod is respectively and vertically fixedly connected with a material blocking plate, the sleeve is provided with a pin hole, the moving rod is provided with a positioning hole with the same inner diameter as the pin hole, and the pin hole is provided with a latch.

[0004] However, the existing greenhouse soil sampling device has many problems in actual operation. First, during sampling, the soil sample is usually collected by driving the sampling pipe to drill into the ground. After the sampling pipe is drilled, it needs to be disassembled to take out the internal soil column. This process is extremely tedious, not only consumes a lot of time and manpower, but also reduces the sampling efficiency. Moreover, when the sampling pipe is disassembled and the soil column is taken out, since the soil column is closely combined with the inner wall of the sampling pipe, a tool is often needed to knock the sampling pipe to make the soil column loose and fall off. However, the knocking force is difficult to accurately control. If the force is too small, the soil column is difficult to take out; if the force is too large, the soil column is easily broken, which causes the sample to be incomplete and affects the accurate detection and analysis of various indexes of the soil, and cannot provide a reliable basis for the scientific management of the greenhouse soil.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a greenhouse soil sampling and testing device includes a body 1. A fixing plate 2 is fixedly connected to the upper surface of the body 1. Two horizontal plates 21 are fixedly connected to one side of the fixing plate 2. A servo motor 25 is fixedly connected to the upper surface of each horizontal plate 21. A reciprocating screw 26 is fixedly connected to the output end of the servo motor 25. The circumferential surfaces of the two reciprocating screws 26 are slidably connected to the same sliding plate 29. A sampling component is provided on the lower surface of the sliding plate 29. The sampling component includes two rotating ring plates 27 rotatably disposed below the sliding plate 29. The two rotating ring plates 27 are spliced ​​together to form a sampling tube. The body 1 corresponds to the two rotating ring plates. A fixing hole 11 is provided at the position of plate 27 for sampling. A support plate 22 is fixedly connected to the upper surface of sliding plate 29. A fixed motor 23 is fixedly connected to the upper surface of support plate 22. The sampling assembly also includes a chassis 28 fixedly connected to the output end of fixed motor 23. Two rotating ring plates 27 are rotatably connected to the lower surface of chassis 28. A connecting motor 210 is fixedly connected to the upper surface of chassis 28. The connecting motor 210 controls the two rotating ring plates 27 to rotate and splice. A feeding assembly is also provided on the upper surface of machine body 1. The feeding assembly includes a semi-ring plate 3 slidably set on the upper surface of machine body 1. The semi-ring plate 3 is used to feed soil columns.

[0024] Specifically, existing greenhouse soil sampling equipment has many problems in actual operation. First, during sampling, it mostly relies on driving the sampling tube to drill into the ground to collect soil samples. However, after the sampling tube has finished drilling, it needs to be removed to take out the soil column inside. This process is extremely cumbersome, not only consuming a lot of time and manpower and reducing sampling efficiency, but also, when removing the sampling tube and taking out the soil column, because the soil column is tightly attached to the inner wall of the sampling tube, it is often necessary to use tools to knock the sampling tube to loosen the soil column and make it fall off. However, it is difficult to accurately control the knocking force. If the force is too weak, the soil column will not be able to be removed; if the force is too strong, the soil column will easily break, resulting in an incomplete sample. This affects the accurate detection and analysis of various soil indicators in the future, and cannot provide a reliable basis for the scientific management of greenhouse soil. Therefore, this invention addresses the aforementioned problem by setting up the above structure. First, when the machine body 1 performs soil sampling, the servo motor 25 and the fixed motor 23 are started. After the servo motor 25 starts, it drives the reciprocating screw 26 to rotate. The rotation of the reciprocating screw 26 drives the sliding plate 29, which is slidably connected on its circumference, to slide downward. The downward sliding of the sliding plate 29 causes the sampling tube, which is spliced ​​from two rotating ring plates 27, to be inserted into the greenhouse soil. During the sampling process, the fixed motor 23 is started, which drives the chassis 28 at its output end to rotate. The rotation of the chassis 28 drives the two rotating ring plates 27 on its lower surface to drill into the soil during the descent process to perform sampling. By separating and splicing the rotating ring plate 27, the sampling tube can be assembled and separated, which can effectively drill soil samples. In addition, the rotating ring plate 27 separated during sampling can perform sampling more quickly without damaging the soil column, reducing the risk of soil column breakage and improving the quality of soil sampling.

[0025] like Figures 1 to 4 As shown, the feeding assembly in this embodiment includes a first slide groove 31 formed on the upper surface of the machine body 1. A lead screw 32 is rotatably connected in the first slide groove 31. A slider 33 is slidably connected on the circumferential surface of the lead screw 32. A connecting block 34 is fixedly connected to the upper surface of the slider 33. Connecting rods 35 are rotatably connected to both sides of the connecting block 34. The same semi-ring plate 3 is fixedly connected to one side of the two connecting rods 35. A bottom plate 36 is fixedly connected to the bottom end of the semi-ring plate 3. A guide groove 310 is formed on one side of the bottom plate 36.

[0026] Specifically, after the sampling work is completed, the lead screw 32 of the first sliding groove 31 is started, and the rotation of the lead screw 32 drives the sliding block 33 arranged on the circumference of the lead screw 32. The sliding block 33 can move close to one side of the rotating ring plate 27. Before driving the sliding block 33 to move close to the rotating ring plate 27, the connecting motor 210 on the upper surface of the chassis 28 is started, and the starting of the connecting motor 210 drives the two rotating ring plates 27 on the lower surface of the chassis 28 to rotate, thereby gradually splitting the two spliced rotating ring plates 27. In the process of rotating the rotating ring plates 27, the sliding block 33 drives the bottom plate 36 and the half ring plate 3 to abut against the soil column. When the two rotating ring plates 27 are completely separated, the bottom plate 36 is inserted below the soil column, and then the electrically controlled connecting rod 35 is rotated to make the half ring plate 3 inclined, so that the soil column is separated from the adhesion with the rotating ring plate 27, thereby completing the discharging work. By starting the lead screw 32 of the first sliding groove 31 to drive the sliding block 33 to move close to the rotating ring plate 27, and cooperating with the connecting motor 210 to drive the rotating ring plate 27 to rotate and split in advance, precise paving is prepared for subsequent discharging. When the rotating ring plate 27 is rotated and split, the sliding block 33 synchronously drives the bottom plate 36 and the half ring plate 3 to abut against the soil column. The action is coordinated and orderly, which effectively avoids the scattering of the soil column during discharging, guarantees the integrity of the sample, and after the rotating ring plate 27 is completely separated, the bottom plate 36 is accurately inserted below the soil column. Then, the electrically controlled connecting rod 35 is rotated to make the half ring plate 3 inclined, so that the soil column is smoothly separated from the adhesion, and the discharging is completed. The whole process has high automation degree and close step connection, which not only improves the discharging efficiency, but also greatly reduces the difficulty of manual operation and the risk of sample damage, and ensures the quality of the sampling work.

[0027] As shown in Figure 4 The upper surface of the bottom plate 36 is embedded with a moving plate 39, the upper surface of the moving plate 39 is fixedly connected with a positioning block 38, the half ring plate 3 is provided with a second sliding groove 37 corresponding to the position of the positioning block 38, and the positioning block 38 can slide along the second sliding groove 37.

[0028] Specifically, after the half ring plate 3 is inclined and moved out by driving the sliding block 33 of the lead screw 32, the positioning block 38 is pulled to drive the moving steel plate to slide along the second sliding groove 37. The moving plate 39 drives the inclined soil column to separate from the half ring plate 3 and perform discharging work, so that the half ring plate 3 can perform discharging of the next soil column, and the discharging efficiency of the soil column is improved.

[0029] Embodiment two: as shown in Figures 1 to 8As shown, the comparative example one, wherein another embodiment of the present application is: each rotating plate ring plate is provided with a cutting assembly, the cutting assembly includes a first groove 211 opened in each rotating ring plate 27, the top wall of the first groove 211 is fixedly connected with two compression springs 213, the bottom end of the two compression springs 213 is fixedly connected with the same arc plate 214, the upper surface of the arc plate 214 is fixedly connected with the magnetic plate 212, the magnetic plate 212 is magnetically attracted to the top wall of the first groove 211, and the bottom end of the arc plate 214 is fixedly connected with the hook plate 215.

[0030] Specifically, when the two rotating ring plates 27 complete sampling, the top wall of the first groove 211 is powered to carry magnetism, repel the magnetic plate 212, then the magnetic plate 212 moves downward to stretch the compression spring 213, the magnetic plate 212 drives the arc plate 214 to move downward, the arc plate 214 drives the hook plate 215 to insert into the bottom end of the soil column in the process of moving downward, cuts off the connection between the bottom end soil column and the land, completes the sampling work, in addition, the arc plate 214 is an elastic plate, after the hook plate 215 inserts into the bottom end of the soil column, the arc plate 214 gradually slides out of the first groove 211 and bends under the repulsion of the magnetic plate 212; The top wall of the first groove 211 is powered to carry magnetism and repel the magnetic plate 212, and the automatic driving is realized by using magnetic force, without complex mechanical structure, so as to reduce the failure rate and maintenance cost, the magnetic plate 212 moves downward to stretch the compression spring 213 and drives the arc plate 214 to move downward, the hook plate 215 accurately inserts into the bottom end of the soil column, can quickly and effectively cut off the connection between the soil column and the land, ensures the completeness of sampling, avoids the damage of the sample, and the arc plate 214 is an elastic plate, which can gradually slide out of the first groove 211 and bend under the continuous repulsion of the magnetic plate 212, this characteristic makes the hook plate 215 better fit the soil column, enhances the cutting effect, at the same time, adapts to different shapes and textures of soil, improves the universality and reliability of sampling, and provides high-quality samples for subsequent accurate analysis of soil.

[0031] As Figure 8 shown, one side of the fixed plate 2 is provided with an auxiliary assembly, the auxiliary assembly includes a first guide rail 41 fixedly connected to one side of the fixed plate 2, a first guide groove 42 is opened in one side of the first guide rail 41, a first guide plate 43 is slidably connected in the first guide groove 42, two auxiliary plates 44 are fixedly connected to one end of the first guide plate 43, and a falling groove 4 is opened in the upper surface of the machine body 1; a plurality of spray holes 45 are opened in the arc-shaped inner wall of the two auxiliary plates 44, a telescopic pipe 46 is fixedly connected to the upper surface of the first guide plate 43, a storage box 24 is fixedly connected to the upper surface of the fixed plate 2, and the first guide plate 43 is in communication with the storage box 24 through the telescopic pipe 46.

[0032] Specific, complete sampling after the unloading work, start the fixed plate 2 side of the auxiliary assembly, start the first guide rail 41 side of the auxiliary assembly, the first guide rail 41 drive its side of the first guide plate 43 inside the sliding, the first guide plate 43 will drive its one end of the two auxiliary plate 44 to move up and down, because the auxiliary plate 44 and rotating ring plate 27 after the rotation of the abutment, the auxiliary plate 44 to move up and down the abutment of the rotating ring plate 27 cleaning work, auxiliary plate 44 to clean up at the same time, the storage tank 24 in the pressurized pump inside the water to the extension tube 46, then along the extension tube 46 pressurized to the first guide plate 43, and then pressurized to the auxiliary plate 44, from the auxiliary plate 44 close to the rotating ring plate 27 side of the nozzle 45 spray, auxiliary auxiliary plate 44 cleaning work, facilitate the storage of equipment.

[0033] The working principle is that first, the servo motor 25 and the fixed motor 23 are started. After the servo motor 25 is started, the reciprocating screw 26 is driven to rotate, and the rotation of the reciprocating screw 26 drives the sliding plate 29 slidingly connected to the circumferential surface to slide downward. The downward sliding of the sliding plate 29 drives the sampling tube below formed by splicing the two rotating ring plates 27 to insert into the soil in the greenhouse. During the sampling process of the spliced rotating ring plates 27, the fixed motor 23 is started to drive the chassis 28 at the output end to rotate. The rotation of the chassis 28 drives the two rotating ring plates 27 on the lower surface to drill into the soil during the descending process to perform the sampling work. In addition, when the two rotating ring plates 27 complete sampling, the top wall of the first groove body 211 is electrified to carry magnetism, repel the magnetic plate 212, and then the magnetic plate 212 moves downward to stretch the compression spring 213. The magnetic plate 212 drives the arc-shaped plate 214 to move downward. The arc-shaped plate 214 drives the hook plate 215 to insert into the bottom end of the soil column during the downward movement of the arc-shaped plate 214, cuts off the connection between the bottom end of the soil column and the land, completes the sampling work, and the arc-shaped plate 214 is an elastic plate. After the hook plate 215 inserts into the bottom end of the soil column, the arc-shaped plate 214 gradually slides out of the first groove body 211 and bends when the magnetic plate 212 repels. After the sampling work is completed, the lead screw 32 of the first sliding groove 31 is started. The rotation of the lead screw 32 drives the sliding block 33 arranged on the circumferential surface. The sliding block 33 can move close to one side of the rotating ring plate 27. Before driving the sliding block 33 to move close to the rotating ring plate 27, the connecting motor 210 on the upper surface of the chassis 28 is started. The starting of the connecting motor 210 drives the two rotating ring plates 27 on the lower surface of the chassis 28 to rotate, thereby gradually disassembling the two spliced rotating ring plates 27. During the rotation of the rotating ring plates 27, the sliding block 33 drives the bottom plate 36 and the half ring plate 3 to abut against the soil column. After the two rotating ring plates 27 are completely separated, the bottom plate 36 is inserted into the lower part of the soil column, and then the connecting rod 35 controlled by the rotation motor is rotated to make the half ring plate 3 inclined, so that the soil column is separated from the adhesion with the rotating ring plate 27, thereby completing the unloading work. And when the half ring plate 3 is inclined, and the sliding block 33 is driven by the driving screw rod 32 to move the half ring plate 3 out, the positioning block 38 is pulled to drive the moving steel plate to slide along the second sliding groove 37, the moving plate 39 drives the inclined soil column to separate from the half ring plate 3, and the blanking work is carried out, so that the half ring plate 3 can carry out blanking of the next soil column, and the blanking efficiency of the soil column is improved; After the sampling and blanking work is finally completed, the auxiliary assembly on one side of the fixed plate 2 is started, the first guide rail 41 on one side of the auxiliary assembly is started, the first guide plate 43 inside one side of the first guide rail 41 is driven to slide, the first guide plate 43 will drive the two auxiliary plates 44 fixed at one end to move up and down, because the auxiliary plate 44 abuts against the rotating ring plate 27 after the rotation is separated, the auxiliary plate 44 abuts against the rotating ring plate 27 and moves up and down to clean the rotating ring plate 27, and the auxiliary plate 44 moves up and down to clean, at the same time, the pressurizing pump in the storage box 24 pressurizes the water in the storage box 24 to the telescopic pipe 46, then pressurizes to the first guide plate 43 along the telescopic pipe 46, and then pressurizes to the auxiliary plate 44, and then sprays from the spray hole 45 on the side of the auxiliary plate 44 close to the rotating ring plate 27, the auxiliary plate 44 cleans to facilitate storage of the equipment.
