Description

Technical Field

[0001] This utility model relates to the field of soil testing, specifically to a soil crushing device for soil testing. Background Technology

[0002] Soil samples need to be sieved before testing to remove impurities such as stones and plant roots. Afterward, the samples need to be crushed to homogenize them and avoid data fluctuations caused by uneven particle distribution. For example, Chinese patent CN222709787U provides a soil sample crushing device, including a crushing body. A cover plate is hinged to the upper left of the crushing body, and a sample plate is fixedly connected to the lower end of the crushing body. A motor is fixedly connected to the lower middle of the sample plate, and the motor's output end passes through the sample plate and the crushing body and is fixedly connected to a crushing structure. The upper left and upper right of the sample plate have holding slots, and three evenly distributed support legs are fixedly connected to the lower end of the sample plate. Two closed covers are provided on the outer surface of the crushing body, located above the two holding slots. Such existing crushing devices generally lack sieving capabilities, requiring the use of a sieve to remove impurities such as stones and plant roots from the sample before it is poured into the crushing device for processing, resulting in low efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a crushing device for soil testing, which solves the problem that existing crushing equipment generally does not have a screening function, and requires the use of a sieve to remove impurities such as stones and plant roots from the sample before it is poured into the crushing equipment for processing, resulting in low efficiency.

[0004] To achieve the above objectives, this utility model provides a soil crushing device, which includes a base housing a motor, a cylinder at the upper end of the base, a rotating shaft connected to the output shaft of the motor inside the cylinder, crushing blades on the rotating shaft, and a cam connected to the upper end of the rotating shaft; a sieve box is detachably mounted on the cylinder, a filter frame is horizontally displaceable inside the sieve box, and the side of the filter frame is connected to the inner wall of the sieve box by a spring; a crossbar is provided at the bottom of the filter frame, and an abutment wheel is provided on the crossbar, with the cam at least partially contacting the abutment wheel.

[0005] Preferably, a groove is formed on the side of the sieve box, and a sliding post is provided on the side of the filter frame, with the sliding post located within the groove.

[0006] Preferably, the lower end of the sieve box is connected to a cylindrical connecting part, which is sleeved on the cylinder.

[0007] Preferably, the outer wall of the cylinder is provided with a buckle body, and the outer wall of the docking part is provided with a hook body that cooperates with the buckle body.

[0008] Preferably, the upper opening of the sieve box is provided with a cover.

[0009] Beneficial Effects: This utility model provides a soil crushing device, which includes a base housing a motor, a cylinder at the upper end of the base, a rotating shaft connected to the output shaft of the motor inside the cylinder, crushing blades mounted on the rotating shaft, and a cam connected to the upper end of the rotating shaft. A sieve box is detachably mounted on the cylinder, and a filter frame is horizontally movable inside the sieve box. The side of the filter frame is connected to the inner wall of the sieve box by a spring. A crossbar is provided at the bottom of the filter frame, and an abutment wheel is mounted on the crossbar. The cam at least partially contacts the abutment wheel. During operation, a soil sample is placed in the filter frame inside the sieve box. A filter screen is provided at the bottom of the filter frame. The motor and the rotating shaft drive the cam to rotate, and the protrusion of the cam intermittently contacts the abutment wheel, thereby causing the filter frame to sway left and right inside the sieve box. After filtration, the soil sample enters the lowered cylinder and is crushed by the rotating crushing blades. The soil testing crushing device provided by this utility model has both the functions of screening and crushing soil samples. Before crushing, the soil sample can be screened to remove impurities such as stones and plant roots, thereby improving the accuracy of soil sample testing.
