The application relates to the technical field of solid-liquid reaction equipment, in particular to a device for solid-liquid reaction. The device is characterized in that a liquid inlet is arranged on the side wall of a reaction body near the top end, so that liquid-phase materials can be fed from the top of the reactor; the disturbance suspension disc is combined with the hollow shaft to make up-and-down reciprocating motion, so that high-concentration liquid-phase materials gradually flow to the bottom of the reaction body; the solid-phase materials are gradually fed into the feeding pipe through the spiral conveying mechanism, and then enter the bottom of the reaction body through the feeding pipe to contact and react with the low-concentration liquid-phase materials formed by reaction; when the disturbance suspension disc makes up-and-down reciprocating motion with the hollow shaft, the solid-phase particles are disturbed to suspend upward, and then contact and react with the liquid-phase materials with higher concentration, so that the relative amount or relative concentration of the solid-phase materials and the liquid-phase materials when they contact is weakened, the intensity of the reaction is weakened, the safety is improved, the small solid-phase materials can be prevented from being wrapped in the product, and the thoroughness of the reaction is improved.

The application provides a furrowing device for crop test, which comprises a base frame, a chute is formed along the length direction of the base frame, and a plurality of furrowing devices are installed in the chute; an open structure is arranged at one end of the chute, a stopper is detachably installed on the side of the open structure, a plurality of clamping grooves are arranged on the side wall of the chute at intervals, and a pressing member is arranged on the other side wall of the chute corresponding to the absence of the clamping groove; the furrowing device comprises a hanging arm which is in sliding cooperation with the chute, the lower end of the hanging arm is provided with an arc-shaped bent arm, the bottom of the bent arm is provided with a plowshare, the top end of the hanging arm is provided with a sliding part which is in sliding cooperation with the upper end surface of the base frame, each hanging arm is clamped into a clamping groove and is tightly pressed by the corresponding pressing member, and the hanging arm is limited in the clamping groove so as to prevent the furrowing device from moving along the length direction of the base frame. The open structure is arranged on one side of the base frame, the furrowing device is convenient to assemble and disassemble, the required number of furrowing devices can be installed according to actual needs, the use and operation are simple, the working efficiency is effectively improved, and the use cost is saved.
