9. The biomass straw drying device according to claim 4, wherein: limiting plate (6) below is equipped with width and is greater than second conveyer belt (2) and is located collecting vat (8) of second conveyer belt (2) below, collecting vat (8) bottom width is less than the opening width, and the tank bottom of collecting vat (8) extends to first conveyer belt (1) and downward sloping, and the hole that leaks near first conveyer belt (1) is still seted up to collecting vat (8) tank bottom, leaks the hole below and is equipped with third conveyer belt (9) to first conveyer belt (1) direction conveying, and third conveyer belt (9) conveying tail end is equipped with lifting belt (10) that promote the straw to on second conveyer belt (2).
10. The use method of the biomass straw drying device is characterized by comprising the following steps:
a. the straws which are soaked and squeezed are put on a first conveyor belt (1) in a strip shape, conveyed by the first conveyor belt (1) to enter a cutting plate (3), cut into segments under the matching of a cutter (4) and a cutting groove, and conveyed to a second conveyor belt (2);
b. the conveying speed of the second conveying belt (2) is lower than that of the first conveying belt (1), so that straws can be stacked on the second conveying belt (2), the height of the straws can be increased, when the straws pass through the limiting plate (6), redundant straws can be blocked by the limiting plate (6), and therefore, part of straws can fall into the collecting tank (8) after turning over the baffle (7), and due to the inclined arrangement of the bottom of the collecting tank (8), the straws can enter the third conveying belt (9) along the bottom of the tank, pass through the lifting belt (10) and return to the second conveying belt (2) again, and due to the limitation of the height of the straws, the amount of the straws falling into the collecting pipe (11) in unit time can be calculated by adding the speed data of the second conveying belt (2), so that quantitative drying can be realized;
c. after a certain period of time, a certain amount of straws are collected in the collecting cylinder, then the valve is opened, the straws fall into the heating box, the rotary disc (15) rotates, the heating box and the disc (13) rotate to a first drying station, namely below the first stirring plate (18), at the same time, the first motor is driven to drive the first lead screw (21) to rotate, so that the height of the first slide block (19) is adjusted, the second lead screw (22) is driven to rotate through the second motor so as to adjust the position of the second slide block (20) on the disc (13), namely, the relative position of the stirring plate (18) on the disc (13) is adjusted, the axis of the disc (13) is positioned at 1/3 of the length of the stirring plate (18), a certain gap exists between the bottom end of the stirring plate (18) and the bottom plate of the heating box, and then the third motor is driven to drive the stirring plate (18) to rotate;
d. when the stirring plate (18) is stirred, the second motor is driven to drive the second lead screw (22) to rotate at the same time, the second stirring plate (18) is driven to move in the direction far away from the axis of the disc (13), the rotation and the movement of the stirring plate (18) are carried out simultaneously, therefore, the movement track of the stirring plate (18) is a spiral line, in the rotating process of the stirring plate (18), straws are uniformly laid on the bottom plate, and the first motor is driven to drive the first sliding block (19) to move upwards, namely, the stirring plate (18) is driven to move upwards, so that the stirring plate (18) moves to the upper part of the heating box;
e. at the moment, the rotary disc (15) rotates to drive the disc (13) to move to a second drying station, namely a second stirring station, namely below the second stirring plate (18), and the straws are accumulated due to the fact that the collecting cylinder concentrates the straws to be placed in a certain range, when the first stirring plate (18) rotates, a part of straws still accumulate in the range, so that the second stirring plate (18) repeats the action of the first stirring plate (18), the straws in the range are evenly paved on the bottom plate, and all straws are evenly separated;
f. at the moment, the rotary disc (15) rotates to drive the disc (13) to move to a third drying station, namely a third stirring station, namely below the third stirring plate (18), and the motion track of the first stirring plate (18) is repeated, so that all straws are further ensured to be uniformly separated;
g. after the three drying stations, the heating box is taken out at the disassembling station, so that the quantitative drying of the straws is completed, and then a new heating box is placed on the disc (13) again at the feeding station.
