A switching mechanism of a piggyback seeder for livestock includes a seed outlet tube arranged downward at the lower end of the seed bag, a cylinder transversely arranged on the side of the seed outlet tube, a vertical pressure plate and a reset spring arranged in the inner cavity of the cylinder from front to back, a front end of the cylinder connected with the seed outlet tube, and a seed outlet tube. A transverse switching socket is arranged, and the side of the seed outlet pipe is provided with a socket. The seed outlet pipe extends out of the socket and connects with the pressing plate. The back end of the cylinder is provided with a back end plate, a through hole is arranged on the back end plate, and a pulling rope is connected at the back end of the pressing plate. The pulling rope extends out of the cylinder through the through hole, and the seed outlet pipe is inserted at the switch. A transverse orifice plate is arranged at the top of the chip, and a plurality of leakage through holes are arranged at the orifice plate, and a plurality of leakage through holes are arranged at the switch socket. When the switch socket is closed, the leakage through holes of the orifice plate and the leakage through holes of the switch socket are staggered from each other. The utility model can control the opening and closing of the seed bag outlet and realize effective seeding.

技术介绍
目前,我国处于不同程度退化中的草地有90%,其中60%以上出现严重退化现象,因此怎样修复退化天然草地是目前亟需要解决的重大问题。目前,天然草地补播主要采用机械播种,机械播种能破坏草地原生植被,一些多年生丛生禾草在机械播种的时候被连根拔起,这样在补播新草种的过程中破坏了原始植被,反而加重了草地退化。并且,机械播种无法在降雨时正常进行,在降雨过程中及降雨后,草地较为泥泞,播种机械通常难以正常进行播种工作,只能等到地面稍微干燥后才能播种,错过了种子最有效的发芽水分条件。同时,机械播种对天然草地碾压较为严重,随着国家严格的草原保护措施的实施,天然草地逐渐禁止机械碾压,这就需要一种更加有效的适合于在天然草地的播种设备来进行草地生态修复。再者,草原的山坡、洼地等区域机械设备难以到达,播种范围受草原地形影响较大,播种范围更小。因此,需要研究一种无需人工及机械操作、成本低、更加节能、能够有效利用草原降雨条件、受草原地形影响小、播种范围更大、并能有效保证种子发芽率的牲畜背驮式播 ...
