When investigating land quality, it is usually necessary to sample and collect the soil in order to test and analyze the soil quality, so as to obtain data information related to land quality. Soil sampling refers to the method of collecting soil samples. When sampling soil, soil sampling and collection equipment is generally used. By drilling the soil sampling and collection equipment into the soil surface, the soil sample of the soil layer to be collected can be introduced into the cavity, thereby realizing the collection of soil for land quality investigation. By investigating land quality, the content of each chemical element in the soil can be found out, providing a data basis for the protection and management of the soil environment and the conservation, intensive and recycling of land resources.

[0003] When switching the water circuit of the pre-filter, a valve is usually required to control or change the path of the water flow to achieve different filtering configurations. Therefore, it is necessary to connect the pipe and the valve. In the prior art, the connection between the pipe and the valve is usually made with the help of bolts or clamps. When the pipe and the valve are installed, the connection between the two cannot be well positioned and supported, so that the stability of the pipe and the valve cannot be well guaranteed during the connection process, and the installation is prone to displacement and misalignment, which will affect the efficiency and effect of the installation, making it difficult to quickly connect the pipe and the valve, and to quickly switch the water circuit. Therefore, in order to solve the above problems, a pre-filter that facilitates water circuit switching is proposed. Utility Model Content

On the surface of the water inlet 11, a water inlet pipe 16 is fixedly connected. At the end of the water inlet pipe 16 away from the water inlet 11, a delivery pipe 17 is fixedly connected. On the surface of the water inlet pipe 16, a first valve 18 is installed. On the surface of the delivery pipe 17, a second valve 19 is installed. On the surface of the water outlet 12, a connecting pipe 110 is fixedly connected. On the surface of the connecting pipe 110, a third valve 111 is installed. Both ends of the third valve 111 are connected to the water inlet 11 and the water outlet 12 respectively through the connecting pipe 110. At the bottom of the third valve 111, a discharge pipe 112 is fixedly connected. Two groups of pre-filter bodies 1 are connected by the connecting pipe 110 and the third valve 111. By opening the first valve 18 on the left group of pre-filter bodies 1, closing the first valve 18 on the right group of pre-filter bodies 1, closing the second valve 19 at the same time, and controlling the third valve 111 to close the discharge pipe 112, water can enter the water inlet pipe 16 through the delivery pipe 17, and then enter the water inlet 11 through the water inlet pipe 16 and enter the left pre-filter body 1. After being treated by the left pre-filter body 1, it can enter the right pre-filter body 1 through the water outlet 12 on the left pre-filter body 1, so that the series connection of the waterway can be realized, and the purity of water can be gradually improved. By opening the second valve 19, opening the first valves 18 on both groups of pre-filter bodies 1 at the same time, controlling the third valve 111 to close the connection between the connecting pipe 110 and the water inlet 11 on the right group of pre-filter bodies 1, and then opening the discharge pipe 112, the water in the delivery pipe 17 can enter the water inlet 11 through the two water inlet pipes 16 respectively, and enter the pre-filter body 1 through the water inlet 11 respectively, to realize the treatment in the two groups of pre-filter bodies 1. The treated water is discharged through the water outlet 12 and discharged through the discharge pipe 112 under the action of the third valve 111, so that the parallel connection of the waterway can be realized, the purpose of waterway switching can be achieved, and each pre-filter body 1 can treat a part of the water flow, which can increase the overall treatment flow rate;

The movable rod 22 can be reset by the setting of the first spring 25, and then the movable rod 22 can drive the connecting rod 23 and the clamping block 24 to reset, thereby realizing the clamping block 24 to clamp the connecting pipe 110 and the discharge pipe 112.

[0027] Furthermore, a replacement mechanism is provided on the inner side of the pre-filter body 1, and the replacement mechanism includes a fixing block 3, which is fixedly connected to the inner wall of the pre-filter body 1, and one end of the fixing block 3 away from the pre-filter body 1 is fixedly connected to a support ring 31, and the surface of the filter element 13 is fixedly connected to a connecting ring 32, and a movable groove 33 is provided on the inner side of the support ring 31, and a limiting rod 34 is fixedly connected to the inner wall of the movable groove 33, and a pull rod 35 is movably connected to the surface of the limiting rod 34, and an insert block 36 is fixedly connected to the surface of the pull rod 35, and a slot 37 is provided on the inner side of the connecting ring 32, and a second spring 38 is fixedly connected to the surface of the pull rod 35, and the insert block 36 can be inserted into and separated from the slot 37 through the movement of the insert block 36, so as to realize the limiting and releasing of the connecting ring 32, thereby facilitating the fixing and removal of the filter element 13 and facilitating the replacement of the filter element 13.

[0028] Further, the support ring 31 is annularly and fixedly connected to the fixed block 3. The connecting ring 32 and the filter element 13 are arranged inside the support ring 31. The pull rod 35 and the insertion block 36 are both movable inside the movable groove 33. Through the arrangement of the support ring 31, the connecting ring 32 and the filter element 13 can be supported and placed, thereby facilitating the installation and use of the filter element 13.

Through the arrangement of the second spring 38, the pull rod 35 can be reset, and thus the insertion block 36 and the insertion slot 37 can be inserted and combined, making it more convenient to fix the filter element 13.

[0030] Working principle: When in use, by pulling the movable rod 22, the movable rod 22 moves on the surface of the fixed rod 2. At this time, the first spring 25 is in a contracted state, enabling the connecting rod 23 to drive the clamping block 24 to move under the action of the movable rod 22, and thus the clamping block 24 is opened. Then, the connecting pipe 110 and the discharge pipe 112 are docked with the third valve 111. Then, the movable rod 22 is released, and the movable rod 22 will be reset under the elastic return action of the first spring 25. Further, the connecting rod 23 will drive the clamping block 24 to be reset, so that the clamping block 24 can clamp the connecting pipe 110 or the discharge pipe 112, facilitating the preliminary fixation of the connection between the connecting pipe 110 and the discharge pipe 112 and the third valve 111, making it difficult for the connecting pipe 110 and the discharge pipe 112 to displace, and thus facilitating the better installation and fixation of the connecting pipe 110 and the discharge pipe 112 to the third valve 111 with tools such as bolts;

[0031] Open the top of the pre-filter body 1 to separate the water inlet 11 and the water outlet 12 from the pre-filter body 1. By pulling the pull rod 35, the pull rod 35 moves on the surface of the limit rod 34 and inside the movable groove 33, causing the insertion block 36 to contract inside the movable groove 33. At this time, the second spring 38 is in a contracted state. Then, the connecting ring 32 and the filter element 13 are placed inside the support ring 31, and the connecting ring 32 is lapped on the support ring 31. Then, the pull rod 35 is released, and the pull rod 35 will be reset under the elastic return action of the second spring 38. Further, the pull rod 35 will drive the insertion block 36 to be reset accordingly, and then the insertion block 36 and the insertion slot 37 are inserted and combined, thereby fixing the connecting ring 32 and completing the installation and use of the filter element 13; When the filter element 13 needs to be taken out and replaced, by pulling the pull rod 35, the pull rod 35 drives the insertion block 36 to separate from the insertion slot 37, and thus the fixation of the connecting ring 32 can be released, and the filter element 13 can be taken out.
