A device for laying trays in the field

Abstract

The invention discloses a disk placing device used for field disk laying operation. The movement of the existing disk-discharging mechanism is inaccurate. Both frame one and frame two of the present invention are provided with a chuck assembly and a tray assembly; the chuck assembly is located above the tray assembly; the chuck assembly includes a chuck follower and a chuck cam; the tray assembly includes a swing lever group, a swing cam, The pallet fixed shaft and the pallet; the chuck cam and the swing cam are driven by the drive assembly to rotate synchronously; the pallet and the pallet fixed shaft are fixed; the two swing rods of the swing rod group are fixed on the pallet fixed shaft; the swing cam is driven by The main cam and the back cam are composed; the main and back cams and the two swing rods of the swing rod group constitute the cam pair respectively. The invention completes the orderly laying of the entire stack of seedling trays one by one through the orderly movement of the chuck follower and the supporting plate, avoiding laying multiple seedling trays at one time; the swing cam is a conjugate cam, which is always connected with the swing rod Maintaining contact ensures precise movement of the oscillating rod and increases the stability of the unit.

Description

technical field [0001] The invention belongs to the technical field of agricultural auxiliary machinery, and in particular relates to a plate placing device used for spreading plates in the field. Background technique [0002] Rice seedling raising is an important production link of rice planting. During seedling raising, it is necessary to complete the processes of sowing, covering soil, and laying trays. With the development of mechanization of agricultural production in our country, rice seedlings are now mostly using precision seeding automatic production lines to improve the quality of seedlings. After passing through the automatic seedling raising line, the soil covering, sowing and soil covering are completed in the seedling raising tray. After sowing, it is necessary to manually place the seedling trays one by one in the seedling hardening shed or the seedling field for seedling cultivation. This process is labor-intensive and requires a large labor force. A mechani...

Problems solved by technology

Although the existing tray laying equipment can complete the operation of seedling raising trays, it still needs manual loading one by one, and cannot complete the work of placing a whole stack of seedling trays

[0004] Invention patent A field tray laying machine (patent application number 201910007933.6) although the tray placement mechanism can complete the tray placement work of the whole stack of seedling trays, but the relaxation of the claws of the tray depends entirely on gravity, the movement of the device is not accurate, and the stability is not stable. it is good

And because the moment arm at the linkage bar is short, the force on the part is relatively large, and the driving force required is relatively large, so the overall force condition is not good
