A continuous grain drying process moisture online detection method. Step 1: delivering to-be-dried grains into a dryer and activating a drying operation; step 2: detecting in real-time a gross weight and a material level and utilizing a relation between moisture content and content weight to calculate moisture content; step 3: either manually or automatically controlling and regulating a grain discharge rate and / or the drying temperature on the basis of real-time changes in the moisture content of the grains, thus allowing the moisture content of the grains discharged by a grain discharging mechanism to be within a range of permitted moisture content thresholds. The method is easy to operate, strong in anti-interference capability, and great in environmental adaptability, is suitable for continuous drying operations for crops such as corn, rice, and wheat, and avoids a major shortcoming of the prior art on moisture content detection.

The invention discloses a vibration prevention based multifunctional indication device. According to the scheme, the device comprises a main trigger unit, an auxiliary trigger unit, a back trigger unit and a front trigger unit that are arranged in a box body, wherein the main trigger unit is provided with a central bearing, side baffles, a top baffle and a main trigger positioned in the main trigger unit; the auxiliary trigger unit is provided with an auxiliary baffle arranged vertically and upwards along the top baffle, and the auxiliary baffle forms an auxiliary trigger restricted in the auxiliary trigger unit together with a frame and a door baffle; when main and auxiliary trigger carriers tilt due to vibration, run to an intersection of the main and auxiliary triggers, collide and quickly return to initial positions, it is displayed that no color is changed in an indication hole; or when the tilt angles of the main and auxiliary trigger carriers are increased to a preset tilt angle, the main and auxiliary triggers do not have the intersection and leave from the initial positions, and it is displayed that the color is changed in the indication hole. Due to the adoption of the scheme, the defects that existing tilt detectors all do not have vibration-proof functions or are complicated in structure, difficult to manufacture, high in cost and inconvenient to popularize although having the vibration-proof functions are overcome; and the device is widely applied to anti-tilt indication of various articles in moving and carrying processes.
