Holder used for portable tree digging machine

Abstract

The invention designs a holder used for a portable tree digging machine, and belongs to the technical field of garden greening machinery instruments. The holder includes a fixing clamping plate, a slewing bearing and a tree digging machine fixing frame; the fixing clamping plate is composed of two arc-shaped plates, the two sides of the fixing clamping plate are symmetrically provided with split bolts and fixing holes, and the split bolts are provided with nuts with fins; the slewing bearing is provided with two rows of balls with different diameters, open areas are arranged on the slewing bearing, and inner and outer bearing rings of the slewing bearing are connected with each other in a clamped mode; the upper and lower rows of balls are arranged on the contact side of the inner bearingring, the two ends of the open area of the inner bearing ring and the two ends of the open area of the outer bearing ring are all of open-type structures, the fixing clamping plate is welded to the inner wall of the inner bearing ring through a retractable rod, a first locating hole is correspondingly formed in the retractable rod, and a first locating bolt is inserted into the first locating hole. The tree digging machine fixing frame is connected with the slewing bearing through a connecting rod, and the tree digging machine fixing bracket is used for placing the portable tree digging machine. The designed holder saves labor during work, and is stable in location and suitable for actual use, the cut soil balls are regular, circular and complete, and the working plane of the holder is easy to adjust.

Description

technical field [0001] The invention relates to the technical field of special mechanical appliances for landscaping, in particular to a support for a portable tree digger. Background technique [0002] With the development of modern society, greening has been paid more and more attention by people. The greening process must involve the transplantation of greening seedlings. At present, there are two kinds of tree digging equipment on the market. One is a large tree digging locomotive. This kind of tree digging locomotive digs trees quickly and has high efficiency. Another kind of tree digging equipment is some portable tree diggers. The purchase cost of portable tree diggers is relatively cheap. It is more suitable for digging some seedlings with higher planting density. However, this portable tree digger needs to be used when working The whole process is carried by manpower, and the cutting trajectory is not easy to control, and it is easy to cut irregular soil balls, wh...

Another kind of tree-digging equipment is some portable tree-digging machines. The purchase cost of portable tree-digging machines is relatively cheap, and it is more suitable for digging some seedlings with high planting density. The whole process is carried by manpower, and the cutting track is not easy to control, it is easy to cut irregular soil balls, which affects the sales of seedlings

The utility model patent with the patent number CN201420423133.5 discloses a portable tree cutting machine with tracks. From the description of this patent document, we can see that this patent adds an arc track, and the chain saw can slide along the arc track. , this patent has achieved the labor-saving effect, but there are also deficiencies: 1. The sliding track of the chain saw is arc-shaped, that is to say, only one arc-shaped working surface can be completed for each cutting, and the track must be moved when it is necessary to continue cutting. The operation is cumbersome, and once the moving position is inaccurate with the previous position, the cut soil ball will also be irregular; 2. The track is a fixed overall structure. When the operating ground is not level, the track will occur Tilting, if you still cut along the track, the soil ball will be cut crookedly, which will affect the sales of seedlings; 3. The radius of the track is fixed, and trees of different thicknesses have different specifications for the soil ball during tree transplantation. To meet the needs of excavating trees of different thicknesses, it is necessary to prepare multiple tracks, which is too expensive
