[0004] In the above scheme, only soil samples of a single particle size can be obtained after impurities are removed. If a control experiment is conducted on soil samples of different particle sizes after impurities are removed, sieves with different apertures need to be replaced and the impurity removal operation needs to be repeated many times. The steps are complicated and there are limitations when using impurity separation equipment for soil testing. Utility Model Content

[0005] In view of the problem that the existing impurity separation devices in the prior art can only obtain soil samples of a single particle size after impurities are removed, if a control experiment is conducted on soil samples of different particle sizes after impurities are removed, sieves of different apertures need to be replaced, and the impurity removal operation needs to be repeated multiple times, which is a complicated process. The utility model provides an environmental detection impurity separation device, which can obtain soil samples of different particle sizes through a one-time impurity separation effect, so as to conduct control experiments on soil samples of different particle sizes. Compared with the method of replacing sieves of different apertures for repeated impurity removal operations, the steps are simpler, and the limitation that the impurity separation equipment can only be used for single particle size soil detection is effectively avoided. The specific technical scheme is as follows:

[0006] An environmental detection impurity separation device comprises an impurity separation unit, wherein a plurality of particle size classification units are arranged below the impurity separation unit, a brush body is slidably arranged in the inner cavity of each particle size classification unit, and the brush bodies in each particle size classification unit are uniformly driven by a driving unit;

[0007] Each layer of the particle size classification unit includes a box body, and also includes a first mesh body installed in the inner cavity of the box body in a horizontal direction, and the brush body is slidably arranged on the upper surface of the first mesh body, and the rear side of the box body is rotatably provided with a sample outlet for closing or opening the inner cavity of the box body;

[0008] Among them, the mesh size of the first mesh in several layers of the particle size classification units gradually decreases from top to bottom.

[0009] In the above technical solution, the driving unit includes a first set of blocks and a second set of blocks installed on both sides of the top of the brush body, and also includes a screw rod rotatable from front to back in the inner cavity of the box body, the first set of blocks is threadedly sleeved on the outer wall of the screw rod, the driving unit also includes a limit rod fixedly installed from front to back in the inner cavity of the box body, and the second set of blocks is slidably sleeved on the outer wall of the limit rod.

[0010] In the above technical solution, the front end of the screw rod extends out of the outer wall of the box body and is installed with a pulley, and the outer wall sliding sleeves of two upper and lower adjacent pulleys are provided with belts.

[0011] In the above technical solution, a base is installed at the bottom of the box at the bottom end, a motor frame is installed on the upper surface of the base, a motor is installed on the top of the motor frame, and the output end of the motor is connected to the screw rod at the bottom end.

[0013] In the above technical solution, the shape of the building block is set to be L-shaped.

[0014] In the above technical solution, the mesh number of the second mesh body is smaller than the mesh number of the first mesh body at the top.

[0015] In the above technical solution, a transparent observation window is provided on the front side of the outer wall of the box.

[0016] Compared with the prior art, the environmental detection impurity separation device of the utility model has the following beneficial effects:

[0017] First, the existing impurity separation device can only obtain soil samples with a single particle size after impurities are removed. If a control experiment is performed on soil samples with different particle sizes after impurities are removed, sieves with different apertures need to be replaced, and the impurity removal operation needs to be repeated for many times, which is a problem of complicated steps. The utility model can obtain soil samples with different particle sizes through a one-time impurity separation effect by arranging a multi-layer box body, a first mesh body, and a sample outlet from top to bottom, so as to conduct a control experiment on soil samples with different particle sizes.

[0021] 6. The utility model can remove impurities contained in the soil by means of the guide bucket, the second net body and the building blocks at the feed hopper, so as to prevent the impurities from entering the inner cavity of the box body and affecting the accuracy of the soil sample test results. The guide bucket is flexible and convenient to disassemble and install, and is easy to operate, so as to clean the impurities separated from the upper surface of the second net body.

[0022] In summary, the utility model can obtain soil samples of different particle sizes in a targeted manner through a one-time impurity separation effect, so as to carry out control experiments on soil samples of different particle sizes. Compared with the method of replacing sieves of different apertures for repeated impurity removal operations, the steps are simpler, and the limitation that the impurity separation equipment can only be used for single particle size soil detection is effectively avoided. The soil samples on the upper surface of the first mesh body of each level are discharged uniformly, which is more convenient than the method of collecting soil samples layer by layer, and the collection of soil samples of different particle sizes does not affect each other, thereby ensuring the accuracy of sampling of soil samples of each particle size.

DETAILED DESCRIPTION

[0028] The following is a combination of specific implementation cases and attached Figures 1 to 4 The present invention is further described below, but the present invention is not limited to these embodiments.

[0029] See also Figures 1 to 4 As shown, an impurity separation device for environmental detection includes an impurity separation unit, through which impurities in a soil sample are removed and separated, and a plurality of layers of particle size classification units are arranged below the impurity separation unit. The following takes the arrangement of three layers of particle size classification units as an example for explanation, through which soil samples of different particle sizes are obtained in a targeted manner, so as to conduct a control experiment on three groups of soil samples of different particle sizes, and a brush body 5 is slidably arranged in the inner cavity of each layer of the particle size classification unit, and the brush body 5 in each layer of the particle size classification unit is uniformly driven by a driving unit, and the brush body 5 in each layer of the particle size classification unit is uniformly driven by the driving unit, so as to assist in pushing and collecting the soil samples separated by each layer of the particle size classification unit;

[0030] Main references Figure 1 and Figure 3As shown, each particle size classification unit includes a box body 1, and also includes a first net body 2 installed in the inner cavity of the box body 1 along the horizontal direction, and a brush body 5 is slidably arranged on the upper surface of the first net body 2. A sample outlet 4 for closing or opening the inner cavity of the box body 1 is arranged at the rear side of the box body 1 through a pin rotation. Soil samples of different particle sizes can be discharged to the outside through the sample outlets 4 opened at different positions. The brush body 5 moves backward along the upper surface of the first net body 2, so that the soil sample on the upper surface of the first net body 2 moves backward to the sample outlet 4 for discharge; wherein, several layers of particle size classification units are provided. The mesh number of the first mesh body 2 in the particle size classification unit gradually decreases from top to bottom. In this embodiment, the mesh number of the first mesh body 2 in the three-layer particle size classification unit is set to 100 mesh, 150 mesh, and 200 mesh from top to bottom, thereby being able to obtain soil samples of different particle sizes through a one-time impurity separation effect, so as to conduct a control experiment on soil samples of different particle sizes. Compared with the method of replacing sieves of different apertures for repeated impurity removal operations, the steps are simpler, and the limitation that the impurity separation equipment can only be used for single particle size soil detection is effectively avoided.

[0031] Main references Figure 3 As shown, the driving unit includes a first set of blocks 6 and a second set of blocks 7 installed on both sides of the top of the brush body 5, and also includes a screw rod 8 rotatably arranged in the inner cavity of the box body 1 through a bearing from front to back, the first set of blocks 6 is threadedly sleeved on the outer wall of the screw rod 8, the driving unit also includes a limit rod 9 fixedly installed in the inner cavity of the box body 1 from front to back, and the second set of blocks 7 is slidably sleeved on the outer wall of the limit rod 9;

[0032] The first set of blocks 6 on the outer wall are driven by the rotation of the screw rod 8 to move the brush body 5 forward, and the second set of blocks 7 on the outer wall of the brush body 5 are driven to move along the outer wall of the limiting rod 9. The brush bodies 5 at different levels are synchronously moved forward along the outer wall of the first net body 2, and the soil samples on the upper surface of the first net body 2 at different levels are assisted to be pushed to the sample outlet 4 at the corresponding position, and the soil samples with different particle sizes are collected separately by opening the sample outlet 4.

[0033] Main references Figure 2 and Figure 3 As shown, the front end of the screw rod 8 extends out of the outer wall of the box body 1 and is installed with a pulley 10. The outer wall sliding sleeves of the two upper and lower adjacent pulleys 10 are provided with a belt 11. When one of the screw rods 8 rotates, it can drive the pulley 10 on its outer wall to rotate, and then the belt 11 drives the other pulleys 10 to rotate synchronously, thereby realizing the synchronous rotation of all the screw rods 8.

[0034] Main references Figure 2As shown, a base 14 is installed at the bottom of the bottom box 1, a motor frame 13 is installed on the upper surface of the base 14, a motor 12 is installed on the top of the motor frame 13, the motor frame 13 provides support for the installation of the motor 12, and the output end of the motor 12 is connected to the bottom screw 8, the bottom screw 8 connected to the output end of the turned-on motor 12 rotates, and then the pulley 10 on the outer wall of the screw 8 drives the belt 11 to rotate, and with the help of the transmission of the belt 11, all the pulleys 10 are caused to rotate in the same direction and synchronously, so as to realize the synchronous rotation of all the screws 8.

[0035] Main references Figure 1 and Figure 4 As shown, the impurity separation unit includes a feed hopper 15 connected to the inner cavity of the top box body 1, and also includes a guide hopper 16 embedded in the inner cavity of the feed hopper 15. A second mesh body 17 is installed in the inner cavity of the guide hopper 16 in the horizontal direction. Blocks 18 are symmetrically installed on the left and right sides of the guide hopper 16, and the blocks 18 are hung at the top edge of the feed hopper 15. The soil sample to be tested is put through the top guide hopper 16, and the impurities stay on the upper surface of the second mesh body 17 under the obstruction of the second mesh body 17, so as to realize the impurity separation of the soil sample; the shape of the block 18 is set to be L-shaped, so that the guide hopper 16 can be quickly assembled or disassembled at the feed hopper 15 with the help of the block 18.

[0036] In addition, the mesh number of the second mesh body 17 is smaller than the mesh number of the first mesh body 2 at the top. In the present embodiment, the mesh number of the second mesh body 17 is set to 80 meshes. Therefore, without affecting the separation of impurities in the soil sample by the second mesh body 17, the soil sample is facilitated to smoothly enter the first mesh body 2 at the top for subsequent soil sample particle size classification processing.

[0037] In order to be able to observe the situation of each layer of soil samples in real time and to make timely adjustments and controls according to the operating status of the equipment, a transparent observation window 19 is provided on the front side of the outer wall of the box body 1. In this embodiment, the material of the transparent observation window 19 is set to a transparent acrylic plate, which is low in cost and meets the needs of transparent observation.

[0038] It is worth noting that a discharge port is provided at the bottom of the bottom box body 1 for discharging the soil that has passed through the outer wall of the bottom first net body 2 .

[0039] The working principle of an environmental detection impurity separation device in this embodiment is as follows:

[0040] The soil sample to be tested is put into the guide bucket 16 at the top, and the impurities are blocked by the second net body 17 and stay on the upper surface of the second net body 17, so that the impurities in the soil sample are separated;

[0041] The soil sample after impurity removal enters the inner cavity of the top box 1, and the first layer of soil samples is obtained under the blocking effect of the first net body 2 in the inner cavity of the top box 1. Similarly, the second layer of soil samples is obtained under the effect of the first net body 2 in the inner cavity of the middle box 1, and the third layer of soil samples is obtained under the effect of the first net body 2 in the inner cavity of the bottom box 1. The soil samples of the three layers are respectively discharged and collected to the outside through the sample outlets 4 at the corresponding positions;

[0042] In order to facilitate the synchronous discharge of soil samples of three layers, the screw rod 8 at the bottom end connected to the output end of the turned-on motor 12 rotates, thereby prompting the pulley 10 on the outer wall of the screw rod 8 to drive the belt 11 to rotate. With the help of the transmission of the belt 11, all the pulleys 10 are prompted to rotate in the same direction and synchronously to achieve the synchronous rotation of all the screw rods 8. The rotation of the screw rod 8 prompts the first set of blocks 6 on the outer wall to drive the brush body 5 to move forward, and at the same time prompts the second set of blocks 7 on the outer wall of the brush body 5 to move along the outer wall of the limit rod 9. The brush bodies 5 of different levels move synchronously to the front side along the outer wall of the first net body 2, and the soil samples on the upper surface of the first net body 2 of different levels are auxiliary pushed to the sample outlet 4 at the corresponding position, and the soil samples of different particle sizes are collected separately through the opened sample outlet 4.

[0043] The utility model can obtain soil samples of different particle sizes in a targeted manner through a one-time impurity separation effect, so as to carry out a control experiment on soil samples of different particle sizes. Compared with a method of replacing sieves of different apertures for repeated impurity removal operations, the steps are simpler, and the limitation that the impurity separation equipment can only be used for soil detection of a single particle size is effectively avoided. The soil samples on the upper surface of the first mesh body 2 of each layer are discharged uniformly, which is more convenient than a method of collecting soil samples layer by layer, and the collection of soil samples of different particle sizes does not affect each other, thereby ensuring the accuracy of sampling of soil samples of each particle size.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
