Detailed Description

For a better understanding of the present invention, embodiments thereof are explained in detail below with reference to the accompanying drawings.

The forestry seedling tray transfer trolley shown in the attached drawings 1-4 comprises a trolley body 1, a lifting frame 2 and a conveyor belt 3, wherein the trolley body 1 comprises a box body 11 with an opening at the side end and four rollers 12 at the bottom end of the box body 11, and the rollers 12 are provided with four rollers. The front and rear inner side walls of the box body 11 are provided with a plurality of layers of seedling tray placing racks 111. The height of the box body 11 is 2-3 m, so that a plurality of layers of tray placing racks 111 can be arranged. The seedling tray placing frame 111 can be fixed on the inner wall of the box body 11 by welding. Also can set up a plurality of screw holes on the inner wall of box 11, as required, the interval of transferring adjacent seedling tray rack 111 earlier then passes through bolt fastening. When in use, the two ends of the seedling tray 4 are loaded on the seedling tray placing rack 111. The opening part of automobile body 1 sets up a crane 2, and crane 2's embodiment is: the lifting frame 2 comprises a support 21, a sliding rod 22, a lead screw 23 and a lead screw driving motor 24, the sliding rod 22 and the lead screw 23 are vertically arranged on the front side and the rear side of the vehicle body 1, two lug plates 211 are respectively extended from the front end and the rear end of the right side of the support 21, a through hole and a threaded hole for the sliding rod 22 and the lead screw 23 to pass through are formed in each lug plate 211, and the lead screw driving motor 24 is arranged on the top end of the vehicle body 1.
