On the other hand, they can also perform a preliminary determination of the carbonate content in the soil, thereby saving the operator's experimental time. When it is necessary to determine the carbonate content in the soil, the soil sample to be tested is placed into the discharge port at the top of the box body, and then the telescopic rod is started to extend and retract. The card block provided at the output end of the telescopic rod will drive the sliding frame where the guide block is located to move horizontally along the bottom end of the V-shaped plate, and the push block provided at the top end of the sliding frame will slide along the filter groove opened on the V-shaped plate.

[0018] (2) The crushing assembly provided in the present invention can further screen the soil screened by the screening assembly, and at the same time crush some of the adhered soil blocks to improve the reaction test efficiency. After the sample falls from the weighing plate to the filter plate, the reel is started to pull the pull rope, and the pull rope will drive the folding pad to contract. At the same time, the pressure roller hinged at one end of the folding pad will move synchronously. At the same time, during the movement of the pressure roller, the driving wheel will rotate under the traction of the elastic belt, so that the pressure roller rotates during the movement and squeezes and crushes the soil sample. At this time, the spring is compressed until the pressure roller moves to contact the limit bar, and the reel can be released to release the pull rope. The spring will drive the pressure roller to reset. Repeat the above steps until the sample is crushed.

[0019] (3) The blower provided in the present invention can blow the crushed sample into the reaction bottle for testing. When the blower is started, the blower will blow the soil sample in the collection box into the guide bin, and then drop it into the reaction bottle through the guide bin. A reference calcium carbonate sample is placed in another reaction bottle, and hydrochloric acid is added to the two reaction bottles through a liquid pump. At the same time, the top cover is rotated to seal the top opening of the reaction bottle. The carbonate content in the soil sample can be calculated by measuring the volume of gas discharged from the gas collecting pipe. BRIEF DESCRIPTION OF THE DRAWINGS
