Hand saw type seedling transplanting machine with soil ball

Technical field

0001The invention relates to a transplanting machine, in particular to a holding saw type seedling transplanting machine with soil ball. Background technique

0002At present, in the seedling market, the seedling and cultivation of tree seedlings are mainly realized by traditional human labor. In recent years, the tree excavators that have appeared on the market mainly include: 1. Single-person operation portable tree excavators. This kind of equipment is manually operated. , The labor intensity is large, the efficiency is low, and it cannot be used for transplanting a large number of ball seedlings. It uses a chain saw chain for cutting, which easily pollutes the roots of the seedlings and seriously affects the survival rate of the seedlings after transplanting; 2. The second seedling transplanter , Borrowing the industrial vehicle chassis, the design has a two-part 1/2 cylindrical working mechanism. This kind of equipment has high cost and large size, which is not conducive to working in nurseries or woods where the seedling spacing is slightly narrow. Due to the cylindrical working structure, The diameter of the soil ball of the tree that can be excavated is small, which cannot effectively cut the thicker tree roots, and has large use limitations; 3.The third type of seedling transplanter, with the help of the industrial vehicle body, adopts a three-part oblique insertion working structure, and is driven by hydraulic pressure. System, this kind of equipment has large dimensions, high production cost and low work efficiency. It cannot effectively cut the thicker tree roots. It is easy to cause the main root system of the tree to be hard torn off, which seriously affects the survival rate of tree transplantation. During the excavation process, large excavation pits are formed around the trees, which are mainly used in large-scale nursery forest farms abroad.

0003Summary of the invention

0004The present invention is to overcome the shortcomings of existing products on the market, and provide a tree digger that can work in a smaller environment with a hybrid power system, which can effectively cut thicker tree roots and reduce the impact on tree saplings during excavation.

The sliding device (which can be a whole or a combination of two or more parts) is nested into the arc-shaped sliding rail one by one, and can be used as an arc-shaped sliding rail. For guiding movement, the arc slide can also be toothed on at least one side, and the sliding device is installed with a walking gear corresponding to it. Arc-shaped movement, and drives the excavating claw installed on the mechanical arm to make an arc-shaped movement. The blades are connected to form a 1/4 spherical shape. The front part of the excavating claw frame surrounds the upper part of the arc-shaped saw frame, and a gap is reserved in the middle for installing the arc-shaped rack, and a pin hole is reserved for installing the pin to make the arc-shaped rack. Closely engaged with the transmission rack, the arc-shaped saw frame is installed in the front of the excavating claw frame, and the axis of the upper part of the arc-shaped saw frame is less than 1/2 of the circular tube shape as the axis to make arc reciprocating The hydraulic device installed on the mechanical arm can control the digging claw and the seedling supporter to open and close left and right. When the pair of digging claws are closed, the digging surfaces of the two digging saws form a hemispherical arc. The arm moves in an arc with the axis of the active shaft as the center of the circle to control the direction of movement of the excavating claw mounted on the mechanical arm. The arc saw frame and the arc saw blade mounted on the excavating claw frame make an arc reciprocating swing. Movement, effective cutting and sawing of the soil and tree roots, and is equipped with a seedling supporter for embracing the trunk; B refers to A, the arc-shaped slide rail described in A plays a supporting and guiding role in the present invention, and is discarded The arc-shaped slide rail is also included in the scope of the present invention by modifying the mechanical arm to use the active shaft sleeve as the support and guide.
