Batch mixing device for soil PH detection

The utility model discloses a batch mixing device for soil PH detection, which comprises a box body, the box body is slidably connected with a mixing plate, the mixing plate is rotatably connected with a push rod, and the box body is rotatably connected with a fixed disc through a rotating shaft; a motor works to enable a fixing disc to rotate clockwise, a push rod moves, a mixing plate slides back and forth in a box body, in the process that the mixing plate slides to be close to a supporting plate, soil is pushed to extrude the supporting plate, the supporting plate slides to abut against the box body, a sliding rod slides to stretch a first spring, and at the moment, the soil is extruded and crushed between the mixing plate and the supporting plate; in the process that a mixing plate slides away from a supporting plate and resets, a first spring pushes a sliding rod and the supporting plate to slide and reset, the mixed soil and the agent are pushed to roll over, the soil and the agent can be better mixed
