The precision seeding technology develops rapidly in recent years and provides higher requirements for seed sowing devices, but the existing air-suction seed sowing device is lack of a device capable of regulating and controlling air volume, the air volume is large each time during seeding, small potato blocks are easily adsorbed on a suction nozzle at the same time, serious reseeding is caused, the waste of the potato blocks is caused, and more energy is wasted.
Disclosure of Invention
The invention aims to solve the problems and combine the sowing requirements of different potato seeds to research and design the air quantity regulating device of the potato air-suction type seed sowing device, and the air quantity regulating device is added to indirectly change the size of the suction nozzle so as to control the adsorption force of potato blocks, so that the aim of sowing various potato seeds with different qualities by the same seed sowing device is fulfilled, and the aims of uniform seed sowing and reduction of rebroadcasting are fulfilled.
The purpose of the invention is realized as follows: the air quantity regulating device of the air-suction seeding apparatus consists of an inner cylinder and an outer cylinder. The sector area of the ventilation part on the bottom surface of the inner cylinder is 1/3 of the bottom surface circle, the two sides of the sector correspond to the two small holes on the side wall of the cylinder for positioning, the bottom surface of the outer cylinder is equally divided into three areas, the common ratio q of the geometric series is 2, and the initial area a of the geometric series is determined according to the sectional area of the suction pipe118.84, the three ventilating surface areas on the bottom surface of the outer cylinder are respectively 18.84mm, 56.52mm and 131.88mm, the difference angle between each area is 120 degrees, and the boundaries of the areas correspond to the small holes on the side wall of the cylinder for positioning. The two cylinders are in clearance fit, and are arranged between a seed suction pipe and a suction nozzle of the seed sowing device after being combined, the inner cylinder is connected to the seed suction pipe through threads, and the suction nozzle is directly sleeved on the outer cylinder to adjust the direction. The air quantity is controlled by controlling the area of the circular holes in the overlapped area exposed by the two cylinders, so that the adsorption force is controlled when the potato blocks are adsorbed. The circular holes on the side surfaces of the cylinders are aligned for positioning, so that the air inlet area is increased or decreased between 18.84mm, 56.52mm and 131.88mm according to the law of equal ratio array, the outer cylinder can be rotated according to the general range of the weight of the potato pieces during sowing, and the relative positions of the two cylinders are adjusted to the positionsThe required air quantity gear can meet the operation requirement.
The invention controls the wind power when the potato blocks are adsorbed by adjusting the air volume adjusting device which increases or decreases the overlapping area between the two cylinders in an equal ratio array, realizes the requirement of seeding potato blocks with different qualities, increases the uniformity of seed sowing and reduces reseeding. Has the characteristics of novel and reasonable and simple mechanism design and convenient adjustment.
