Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a soil column leaching device for soil testing that is easy to observe. Background Technology

[0002] When conducting leaching tests on soil, it is necessary to collect the soil to be tested. However, most current testing equipment is not convenient for testing personnel to observe during the testing process, making it difficult to accurately record the test data. Furthermore, it is inconvenient to clean the soil in the testing device after the test, thus wasting a lot of time cleaning the testing device.

[0003] Publication number CN215066646U discloses a soil column leaching device for easy observation in soil testing, relating to the field of soil testing technology. This easy-to-observe soil column leaching device includes a base with a rotating mechanism mounted on it. A first side plate and a second side plate are fixedly installed on the top of the base. In this device, the glass cup can collect the mixed liquid discharged from the testing glass tube during soil leaching testing. This not only improves the cleanliness of the testing environment but also collects dripping pesticides from inside the testing glass tube during leaching, thereby reducing pesticide residue pollution. Furthermore, the front of both the placement box and the pesticide storage box are equipped with graduation lines, facilitating recording and comparison by testing personnel during the testing process. This not only improves the efficiency of testing records but also enhances the overall work efficiency of the testing personnel.

[0004] While the above scheme facilitates recording and comparison by testing personnel, the soil testing container needs to be rotated and its angle adjusted by operating the gear transmission mechanism when it is removed from the placement box. The rotation and adjustment when the equipment is moved to remove the soil testing container can easily cause it to fall off and be damaged, and soil to spill. Furthermore, when pesticides are introduced into the two soil testing containers through diversion, uneven diversion can affect the comparative testing results. Therefore, we propose a soil column leaching device for soil testing that is easy to observe. Utility Model Content

[0005] The main purpose of this invention is to provide a soil column leaching device for soil testing that is easy to observe. By setting a limiting unit and a liquid distribution and collection unit, it solves the problems that the rotation adjustment when the equipment is moved and the soil testing container is removed can easily cause it to fall off and be damaged, and soil can be spilled. It also solves the problem that when pesticides are introduced into the two soil testing containers by diversion, the flow is uneven and affects the comparative detection effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a soil column leaching device for soil testing that is easy to observe, including a support frame and an observation discharge tube, and further including: a limiting unit and a liquid separation and collection unit set on the support frame, wherein the bottom part of the observation discharge tube is in the shape of a hollow frustum, and the observation discharge tube is mainly used to hold the soil to be tested;

[0007] The limiting unit includes a rectangular frame plate, a longitudinal support plate, a clamping arc plate, a limiting ring, a bidirectional screw rod, an adjusting strip plate, and a clamping arc plate. The rectangular frame plate is hollow inside and fixedly disposed between the inner walls of opposite sides of the support frame. Two longitudinal support plates are provided and symmetrically fixedly disposed on the top surface of the rectangular frame plate. The two clamping arc plates are respectively fixedly disposed at the center of the surface of the longitudinal support plate facing the vertical central axis of the rectangular frame plate. The two limiting rings are respectively fixedly disposed at the bottom ends of the two clamping arc plates. The bidirectional screw rod is movably disposed on the inner wall of one end of the rectangular frame plate. The two adjusting strip plates are respectively engaged with the two symmetrically disposed positive and negative threads on the bidirectional screw rod. The clamping arc plate is fixedly disposed on the surface of the adjusting strip plate near the clamping arc plate and located above the limiting ring. The two observation and feeding tubes are respectively placed on the two limiting rings. A turntable is fixedly disposed at one end of the bidirectional screw rod that extends movably to the outside of the rectangular frame plate.

[0008] The liquid separation and collection unit includes a discharge vertical pipe, a dispensing cylinder, a switch valve, and a measuring cup. The two discharge vertical pipes are symmetrically fixed and embedded on the top surface of the support frame and located directly above the two limiting rings. The two dispensing cylinders are respectively fixedly installed at the top of the two discharge vertical pipes, and a first graduation groove is provided on the outer circumference of the dispensing cylinder. The two switch valves are respectively fixedly installed on the outer circumference of the two discharge vertical pipes. The inner bottom surface of the support frame has two symmetrically opened positioning grooves, and the two measuring cups are respectively placed on the two positioning grooves.

[0009] Preferably, the limiting unit further includes a guide rod, which is fixedly mounted on the inner wall of the other end of the rectangular frame plate and movably passes through the two adjustment strips.

[0010] Preferably, the bidirectional lead screw and the clamping arc plate are arranged perpendicular to each other.

[0011] Preferably, the abutting arc plate and the clamping arc plate are arranged opposite to each other.

[0012] Preferably, a second graduated groove is provided on the outer circumferential surface of the observation discharge tube.

[0013] Preferably, the support frame is fixedly provided with four legs at the bottom corners, arranged in a rectangular array.

[0014] Preferably, a support ring is fixedly provided on the inner wall of the bottom end of the observation discharge tube, and a circular filter plate is placed above the support ring.

[0015] Compared with existing technologies, the soil column leaching device for soil testing of this utility model, which is easy to observe, has the following beneficial effects:

[0016] 1. In this utility model, by setting a limiting unit, before the pesticide is introduced into the observation and discharge tube, a limiting ring fixed below the rectangular frame plate by a longitudinal support plate and a clamping arc plate can provide bottom support and limit the observation and discharge tube directly below it. By holding the turntable, the bidirectional screw can be controlled to rotate forward and backward on the rectangular frame plate. The relative movement of the two longitudinal support plates threaded to the bidirectional screw can drive the two clamping arc plates to adjust the distance. The guide rod can guide the longitudinal support plates to slide and provide auxiliary support. After the distance between the two clamping arc plates is opened, the two observation and discharge tubes can be clamped and limited on the clamping arc plates to complete the assembly. After the distance between the two clamping arc plates is opened, the observation and discharge tubes can be moved upward and horizontally inside the rectangular frame plate to remove them and complete the subsequent soil unloading. The equipment assembly and removal of the observation and discharge tubes is flexible and stable and will not fall off, be damaged, or cause soil spillage.

[0017] 2. In this utility model, by setting up a liquid separation and collection unit, after closing the two switch valves respectively fixed on the outer circumference of the two discharge vertical pipes, the pesticides introduced into the two discharge cylinders are temporarily stored. The first scale groove on the outer circumference of the discharge cylinder can be used to determine and control the pesticides temporarily stored on the two discharge cylinders to maintain the same amount. After the discharge pipe is assembled, the two switch valves are opened at the same time, and the two pesticides with the same amount can be introduced into the two observation discharge pipes at the same time for comparison of leaching effect. The two measuring cups restricted by the positioning groove directly below the two observation discharge pipes can be used to help personnel observe the amount of pesticide dripped and collected after leaching the two parts of soil for further comparative analysis. The equipment ensures that the pesticide distribution of the leached soil is consistent and guarantees the comparative detection effect. Attached Figure Description

A double-acting screw 205 is controlled to rotate forward and backward on the rectangular frame plate 201 by a handle turntable. The two longitudinal support plates 202, threaded to the double-acting screw 205, move relative to each other under force, causing the two clamping arc plates 203 to adjust their spacing. A guide rod 208 guides the longitudinal support plates 202 to slide and translate. After the two clamping arc plates 203 are spaced apart, the two observation and discharge pipes 4 are clamped and limited on the clamping arc plates 203, completing the assembly. The two pipes respectively fixed to the outer circumference of the two discharge vertical pipes 301 are then closed. After the switch valve 303 is turned on, pesticides in the two discharge cylinders 302 are temporarily stored. The first scale groove on the outer circumference of the discharge cylinder 302 is used to determine and control the pesticides temporarily stored in the two discharge cylinders 302 to maintain the same amount. After the discharge pipe 4 is assembled, the two switch valves 303 are turned on at the same time, and the two pesticides with the same amount are introduced into the two observation discharge pipes 4 for comparison of leaching effect. The two measuring cups 304, which are restricted by the positioning grooves directly below the two observation discharge pipes 4, are used to help the personnel observe the amount of pesticide dripped and collected after leaching the two parts of soil for further comparison and analysis. After the two clamping arc plates 203 are opened, the observation discharge pipe 4 is moved up and down inside the rectangular frame plate 201 to remove it and complete the subsequent soil unloading.
