Design and testing of a double-tray symmetrical staggered automatic seedling extraction device for tobacco pot seedlings
In order to solve the problems of high labor and low efficiency of tobacco semi-transplanting,a symmetrical staggered automatic seedling picking device was designed.First of all,the principle of the automatic seedling picking device for staggered picking of two trays of seedlings was described,and the kinetic and kinematic models of the picking and dropping operation were established.Then,the key components of the seedling picking device such as tray feeding device,seedling picking device and automatic control system were designed,the operation process of the key components was analyzed,and the selection of key components was completed according to the actual requirements.Finally,Based on the existing transplanter power chassis,a prototype of 2ZY-1 tobacco transplanter was made,and the performance test was conducted with 60-day-old tobacco seedlings in the field.The test results showed that the success rate of seedling picking was 89.63％,the success rate of seedling dropping was 97.20％and the injury rate was 3.59％when the automatic seedling picking and dropping speed was around 20 plants/min.
