The utility model discloses a
greenhouse corn planting
transplanting seedbed frame, including a plurality of elevating
system, a plurality of elevating
system all include two casing, two casing are commonly installed with manual drive
assembly, two
power output of manual drive
assembly all are fixedly connected with two -way screw rod, two two -way screw rod's outer surface all symmetrical thread sleeve joint has two
round bar, two
round bar's outer surface commonly rotatory sleeve joint has upper connecting rod subassembly and lower connecting rod subassembly, two upper connecting rod subassembly between commonly fixedly connected with the top plate, two lower connecting rod subassembly between commonly fixedly connected with the groove tray. In the utility model, through worm
gear drive drive two -way screw rod rotation, drive upper and lower connecting rod subassembly linkage, make the top plate and groove tray synchronous lifting, and the worker reduces the height layer by layer according to the demand when
transplanting operation, avoids the traditional fixed
seedbed frame because of the upper layer too high and leads to the climbing operation of avoiding, and the safety and efficiency of
transplanting are improved obviously.
