Saw-holding type soil ball-carried seedling transplantation machine

Abstract

The invention discloses a saw-holding type soil ball-carried seedling transplantation machine comprising a machine body, a pair of mechanical arms attached to arc-shaped slide rails and equipped withsliding devices, a pair of digging paws and seedling straightening devices. The mechanical arms conduct arc-shaped movements along the arc-shaped slide rails via the sliding devices and with an axis of a driving wheel as a circle center and drives the digging paws mounted on the mechanical arms to move in an arc way; a hydraulic device mounted on the mechanical arms can control left-right openingand close of the digging paws and the seedling straightening device; when the pair of digging paws are closed, digging surfaces of two digging saws form hemispherical radian; arc-shaped saw rack and arc-shaped saw webs mounted on the digging paw racks swing and effectively cut and saw soil and tree roots off; a cutting shape is hemispherical; a connection distance between the mechanical arms withthe sliding devices and transmission sleeves can be adjusted; with the combination of the exchangeable and detachable arc-shaped saw webs, soil balls with different sizes can be cut as needed; the cutting surface is smooth and standard; and the saw-holding type soil ball-carried seedling transplantation machine has advantages in particular upon frozen earth work.

Description

technical field [0001] The invention relates to a transplanting machine, in particular to a holding saw type seedling transplanting machine with soil balls. Background technique [0002] At present, in the seedling market, the seedling and cultivation of tree seedlings are mainly realized by traditional manual labor. The tree excavators that have appeared in the market in recent years mainly include: 1. Portable tree excavators operated by one person. , high labor intensity, low efficiency, can not be used for the transplanting of a large number of bulb seedlings, it is cut with chainsaw chains, which is easy to contaminate the root system of the seedlings, and seriously affects the survival rate of the seedlings after transplanting; 2. The second seedling transplanting machine , Borrowing the chassis of industrial vehicles, it is designed with a two-lobed 1 / 2 cylindrical working mechanism. This kind of equipment has high cost and large size, which is not conducive to workin...

Problems solved by technology

[0002] At present, in the nursery stock market, the raising and cultivation of tree seedlings are mainly realized by traditional human labor. The tree digging machines that have appeared on the market in recent years mainly include: 1. Portable tree digging machines operated by a single person. , labor intensity is big, efficiency is low, can not be used for the transplanting of a large amount of ball seedlings, and it adopts chainsaw chain to cut, easily pollutes seedling root system, seriously affects the survival rate of seedlings after transplanting; 2, the second kind of seedlings transplanting machine , borrowing the industrial vehicle chassis, designed with two 1 / 2 cylindrical working mechanisms, this kind of equipment has high cost and large size, which is not conducive to working in nurseries or forests where the distance between seedlings is slightly narrow, because of the cylindrical working structure, The diameter of the tree soil ball that can be excavated is small, and it cannot effectively cut off the thicker tree roots, so the use limitation is large; 3. The third seedling transplanting machine, with the help of the industrial vehicle body, adopts a three-lobed oblique insertion working structure, and uses hydraulic pressure Drive system, this kind of equipment has large dimensions, high production cost, and low work efficiency. It cannot effectively cut off the thicker tree roots, and it is easy to cause the main root system of the tree to be torn off, which seriously affects the survival rate of tree transplanting.
