[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] like Figure 1-Figure 4As shown, a pneumatic stratified fertilizer dispensing device comprises a seat body 1, outer ring blades 2, connecting rods 3, inner ring blades 4 and a double-groove connecting plate 5, wherein the outer ring blades 2 comprise outer ring bottom blades 201 and outer ring top blades 202, a plurality of outer ring bottom blades 201 are evenly spaced on the bottom end surface of the seat body 1 and one end of the outer ring bottom blades 201 is hinged to the bottom end surface of the seat body 1, the other end of the outer ring bottom blades 201 is hinged to one end of the outer ring top blades 202, the upper part of the outer ring top blades 202 is hinged with connecting rods 3, the other end of the connecting rods 3 is hinged to the seat body 1, and the outer ring blades 2 can be rotated around the hinge point by pushing and pulling the connecting rods 3, and the inner ring blades 4 comprise inner ring bottom blades 40 1 and outer ring top blade 402, the inner ring bottom blade 401 is arranged between two adjacent outer ring bottom blades 201 and one end of the inner ring bottom blade 401 is hinged to the bottom end surface of the seat body 1, and the other end of the inner ring bottom blade 401 is hinged to one end of the inner ring top blade 402, a fixing pin is arranged on the inner ring top blade 402, the two ends of the double groove connecting plate 5 are symmetrically provided with sliding grooves, the middle part of the double groove connecting plate 5 is connected to the fixing pin, a pin is inserted in the sliding groove, and the pin is fixed on the outer ring top blade 202, the outer ring bottom blade 201 and the inner ring bottom blade 401 are both rectangular structures, and the outer ring top blade 202 and the outer ring top blade 402 are both rectangular structures. In order to ensure the roundness of the cross section of the area enclosed by the outer ring blades 2 and the inner ring blades 4, it is more preferred that the number of the outer ring blades 2 and the inner ring blades 4 is the same and not less than 10. In order to ensure the stability of the relative movement between the outer blade 2 and the inner blade 4, the number of the fixing pins of the inner top blade 402 is not less than two, and the fixing pins are all arranged on the symmetry line of the inner top blade 402. An air duct 6 is arranged inside the seat 1, one end of the air duct 6 is sealed, and the other end is connected to the fan, and the sealed end of the air duct 6 extends out of the seat 1. When the outer blade 2 and the inner blade 4 shrink under the action of the connecting rod 3, the outer blade 2 and the inner blade 4 can contact and cooperate with the sealed end of the air duct 6 to close the fertilizer discharger and prevent the fertilizer from falling. The middle part of the air duct 6 is connected with a plurality of arc tubes along the circumference, and the other end of the arc tube is fixed on the inner wall surface of the seat 1. The outer arc surface of the arc tube is provided with a plurality of ventilation holes. The wind of the fan enters the arc tube through the air duct 6 and then sprays out through the ventilation holes of the arc tube. The sprayed wind will stir the fertilizer under the action of the arc tube structure and promote the fertilizer to fall. Preferably, the opening of the ventilation hole on the arc tube is downward and the angle between the axis of the ventilation hole and the horizontal plane is 45 degrees, which can better provide wind force for the fertilizer to spiral downward, so that the fertilizer can fall more smoothly with the help of wind force and more easily reach the soil where it is applied.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
