Compared with the third embodiment, because the elastic cushion block 804 is arranged, and when the push block 502 and the cylinder 503 descend, the elastic cushion block 804 is just positioned under the cylinder 503, so that the cylinder 503 collides with the elastic cushion block 804, vibration can be effectively reduced, and rigid collision between the cylinder 503 and the surface of the sliding rod 801 is avoided, so that the service life is longer.
Example five:
referring to fig. 1 to 10, on the basis of the fourth embodiment, a flow guide cavity 6 is fixedly installed at the bottom of the housing 2 for guiding seeds during sowing, and the flow guide cavity 6 is matched with the push block 502 in size.
In the present embodiment, it is preferable that: after the sliding rod 801 pushes the seeds out of the storage bin 302, the seeds may fall along a parabolic track, and at this time, the rapid descending of the push block 502 cannot necessarily push all the seeds out of the shell 2; and the flow guide cavity 6 is arranged, so that the seeds are gathered when the sliding rod 801 pushes the seeds, and the ejection sowing of the push block 502 is facilitated.
The working principle and the using method of the invention are as follows: during use, the shell 2 is driven to move to a position to be sowed through the unmanned aerial vehicle body 1, then the starting motor 301 drives the storage bin 302 and the guide groove 303 to rotate, at the moment, the contact between the cylinder 503 and the guide groove 303 moves from the lower end of the descending section to the other descending section along the ascending section, in the process, the cylinder 503 drives the push block 502 to ascend, and the push block 502 drives the base 501 to ascend along the support 4 and extrude the first spring 504; the base 501 further drives a third pulling rope 7003 to ascend through the matching of structures such as the cross clamping groove 10, the movable pulley 7001 and the second pulling rope 7002, the third pulling rope 7003 drives the square block and the inserted bar to descend and stretch a fourth spring, when the square block descends, the two sliding bars 801 are driven to move towards the inside of the storage bin 302 and extrude the second spring 803 through the matching of the inserted bar and the wedge-shaped hole 802, when the sliding bars 801 move into the storage bin 302, seeds in the storage bin 302 are exposed outwards from the through holes where the sliding bars 801 move and roll to the lower end of the descending section of the guide groove 303.
Then the motor 301 stops rotating, the storage bin 302 and the guide groove 303 also stop rotating, at this time, the cylinder 503 enters another vertical descending section, and in the process, under the action of the first spring 504, the cylinder 503 and the bracket 4, the base 501 drives the push block 502 to descend rapidly along the bracket 4; the pulling force on the second pulling rope 7002 is relieved when the base 501 descends, so that the movable pulley 7001 automatically descends due to gravity, the square block quickly ascends under the action of the fourth spring at the moment, the third pulling rope 7003 is tensioned again when the square block ascends, the inserting rods on two sides are driven to synchronously ascend simultaneously, the inserting rods are matched with the wedge-shaped holes 802 to drive the two sliding rods 801 to move towards the outside of the storage bin 302 when ascending, the seeds positioned at the lower end of the descending section are pushed out from the storage bin 302 and then matched with the quick descending of the pushing block 502 to complete seeding, and finally the motor 301 is started again and reciprocates in sequence.
Through the matching of the structures such as the first spring 504, the push block 502, the descending section and the cylinder 503, the seeds can be ejected out of the shell 2 in an ejection state, and then enter the inside of the position to be sowed, so that the seeds can be more favorably germinated and grown; through the matching of the structures such as the movable pulley 7001, the second pull rope 7002, the third pull rope 7003 and the cross-shaped clamping groove 10, the horizontal moving distance of the two sliding rods 801 can be changed, the situation that seeds in the storage bin 302 fall too much from a through hole at one time is avoided, the actual seeding quantity requirement is met, meanwhile, a labor-saving design is formed, a square block can be pulled among a large number of seeds more easily, and the seeds are conveyed by matching with the wedge-shaped hole 802; through the cooperation of structures such as slide bar 801, elastic cushion block 804 and decline section, can cushion the fast decline of cylinder 503, reduce cylinder 503 and slide bar 801's striking injury, improve holistic life, satisfied more demands in the in-service use.
