1. A self-propelled picking vehicle for pineapples based on scraper transportation, comprising: a baseplate (1), a driving mechanism (2), and a propelling mechanism (3); wherein the driving mechanism (2) is disposed on the baseplate (1), the propelling mechanism (3) is disposed at a lower end of the baseplate (1), and the driving mechanism (2) is connected to the propelling mechanism (3); a front end of a horizontal chain conveyor (4) is provided with a cutting plate (6); the cutting plate (6) is provided with two disk blades (7), outer sides of the two disk blades are provided with dividers (16), and a fruit protector (8) is disposed between the two disk blades (7); and a fruit picking mechanism (9) is disposed at an upper end of the fruit protector (8);
wherein the fruit picking mechanism (9) comprises a first support (901), a second support (902), a rotating shaft (903), fruit picking plates (904) and a power unit (905); the rotating shaft (903) is rotatably fixed by the first support (901) and the second support (902), and an end of the rotating shaft (903) is connected to an output end of the power unit (905); the fruit picking plates (904) are coaxially connected to the rotating shaft (903);
wherein a vertical rotating and lifting chain conveyor (5) is disposed at a rear of the baseplate (1), and the horizontal chain conveyor (4) is configured to convey picked pineapples to the vertical rotating and lifting chain conveyor (5);
wherein the horizontal chain conveyor (4) and the cutting plate (6) located in the front end of the horizontal chain conveyor (4) are connected to the baseplate (1) through a hydraulic cylinder (10); the cutting plate (6) disposed at the front end of the horizontal chain conveyor (4) is adjusted through the hydraulic cylinder (10) to adapt to different cutting heights;
wherein impetus of the vertical rotating and lifting chain conveyor (5) is distributed through the driving mechanism (2) and transmitted using chain transmission; chain conveyor scrapers (12) are sandwich composite materials, a middle of each of the chain conveyor scrapers (12) is a steel plate (13) capable of providing a supporting force, and an outside of each of chain conveyor scrapers (12) is wrapped by a rubber flexible material (14) to reduce mechanical contact with fruits and damage to the fruits; and each of the chain conveyor scrapers (12) is covered with the rubber flexible material (14) to protect the fruits; and
wherein the horizontal chain conveyor (4) and the vertical rotating and lifting chain conveyor (5) have relatively independent transmission to rotate independently, a height difference is provided between a tail end of the horizontal chain conveyor (4) and the vertical rotating and lifting chain conveyor (5), and the height difference is in a range of 10-12 centimeters (cm) to ensure that the fruits fall without damage.
