The invention has the technical effects and advantages that:
(1) When a worker judges that red dates are not on the ground through naked eyes, the rectangular closing plate can be closed by adjusting the first electric push rod on the electric control handle pickup device, at the moment, air flow cannot enter from the rectangular inclined suction port, impurities such as red dates cannot be sucked, the rectangular closing plate can be controlled to be opened by adjusting the opening button on the electric control handle in the same way, the ground red dates are picked up, and the purpose of selective pickup is achieved by controlling the opening and closing of the rectangular closing plate;
(2) The trunk-type impurity removing and separating box can well separate impurities from materials without damaging the materials, the gradual flaring can spray the materials from the impurities and reduce the acceleration of the materials, at the moment, the airflow speed of the trunk-type impurity removing and separating box can not suspend the materials, the materials impact a baffle plate to fall, and due to the fact that the impurities are lighter in weight and smaller in volume compared with the materials and are subjected to negative pressure suction airflow effect generated by an impurity removing device, the impurities can pass through a fence along with the airflow in the falling process and are crushed and discharged through an electric impurity crushing roller, the rotating speed of the electric impurity crushing roller can be adjusted through a rotating speed adjusting knob on a control panel, the crushed impurities are easier to discharge, the pipeline is prevented from being blocked, and the fence is not only a passing area of the impurities but also is prevented from being crushed by the electric impurity crushing roller along with the movement of the impurities;
(3) When the air speed is adjusted and the motor rotating speed adjusting knob is rotated respectively, the working states of the blower, the second motor, the first motor and the water pump can be controlled respectively, the air quantity in the pipeline is insufficient, the air quantity in the pipeline is not communicated with the material flow, the air sensor and the solid flowmeter adjust the gear of the blower, so that the wind power of the blower is increased, and when the machine fails in working engineering, the emergency stop button is pressed to stop the working of all working parts;
(4) The discharging impurity removing device can remove impurities mixed in the materials for the second time, impurity removing gaps are formed in the lower half part of the shell of the discharging device and the discharging inclined plate, after the gap width is limited, the materials can be prevented from being discharged, the impurities are discharged from the gaps in the rotation process of the discharging roller, and impurities such as soil blocks, small stone particles and the like can be discharged from the gaps;
(5) When the air flow of the end cannot meet the flow of the picked up materials, the air flow sensor controls the rotating speed of the air blower, so that the air flow of the inlet is regulated to regulate the suction force of the suction port, the air blower always maintains the rotating speed at the minimum air flow capable of picking up the red dates, when the rectangular closing plate is closed, the curved closing plate is opened, the end does not have air circulation at the moment, the air flow sensor does not work, and the air blower is regulated to be in an energy-saving gear; when the rectangular closing plate is opened, the pickup device works, materials and air circulate in the material conveying device, the air flow sensor and the solid flowmeter start to work, the solid flowmeter is arranged at the venturi tube shrinkage reducing section, the section is easy to be blocked, and when the material flow of the section is large, the solid flowmeter controls the air speed of the blower to adjust so as to prevent the blockage, and the material congestion is avoided.
