Immersing water trough of stem washer

The utility model relates to an immersion water tank device of a stalk washer, which comprises a water tank and a rotating roller which is connected with the inner part of the water tank. The bottom of the immersing water tank device of a stalk washer is provided with a groove, and the depth of the groove is larger than the depth of a tank body of the water tank; a rotating roller of which the periphery is distributed with blades is arranged in the groove; the rotating roller is supported and connected with a support frame; a motor is connected with the rotating roller by a transmission mechanism. Tobacco stalks can be forcibly pressed into water by the blades which are driven by the rotation of the rotating roller. The utility model increases the water absorption area of the tobacco stalks, and achieves the purpose of the whole surfaces of the tobacco stalks can all absorb water content. The movement speed of the tobacco stalks under the driving of the rotating roller is slower than the original movement speed of the tobacco stalks following water flow, and the immersion time can be enhanced. The wet depth of the tobacco stalks can be enhanced largely, and the quality of immersion stalks can be enhanced.
