Description

Disc-toothed cutter-type tree transplanting excavator

technical field

The invention provides a disc-toothed cutter type tree transplanting excavator, which belongs to the technical field of garden machinery.

Background technique

At present, different varieties of arbors are planted on the sidewalks on both sides of domestic urban roads. In order to achieve urban greening and viewing and shade in summer, arbors that are more than 5 to 10 years old must be transplanted. During the transplanting process, the survival rate must be guaranteed. Now For domestic transplanting, the lateral roots around the trees are mainly cut off manually with a shovel or shovel, and then the main lateral roots of the trees are cut off. If the lateral roots of the transplanted trees are short, the survival rate of the transplanted trees is low; if the lateral roots of the transplanted trees are long, keep the fibrous roots against the roots The damage is small, and the survival rate of tree transplanting is high, but manual excavation is labor-intensive, labor-intensive and time-consuming, and the efficiency is low.

The patent 200610039487 tree transplanting excavator drives the digging shovel through six oil cylinders, which consumes a lot of power, and it is difficult to excavate the trees with older trees and thick lateral roots, and it is difficult to use a shovel for trees with thick taproots.

Foreign tree transplanting excavators have complex structures and are expensive, and are not suitable for domestic excavation requirements.

Contents of the invention

The purpose of the present invention is to provide a kind of can overcome the defect of existing tree transplanting excavator, the disc-toothed cutter driven by power rotates, the cutting radius is determined according to the age of the tree, and the cutting is cut off by the rotation of the disc-toothed cutter. The lateral roots of the trees are rotated out at the same time, and the angle of the disc-toothed cutter is adjusted to cut the lateral roots, which consumes less power and has high efficiency.

Working principle: According to the rotary centrifugal cutting principle of disc saw teeth, the toothed saw blade is applied to the tree root cutting, and the soil is rotated out while cutting off the main root and lateral root of the tree.

Its technical scheme is.

A disc-toothed cutter-type tree transplanting excavator includes a trolley, a diesel engine, a double-acting oil cylinder, a disc-toothed cutter and a reducer. The diesel engine is located on the upper surface of the platform of the trolley frame, and the thrust handle is located on the On the chassis of the trolley, there is a walking wheel on the end face of the thrust handle, a steering wheel on the other end face, and a double-acting lifting cylinder on the chassis of the trolley. The double-acting lifting cylinder extends the frame in the transportation state. During operation, the double-acting lifting cylinder shrinks the frame and descends, and the two ends of the rotating shaft pass through the bearings and are installed on the frame, and are fixedly connected with the lower surface of the platform. The diesel engine drives the transmission shaft to rotate through the coupling, drives the reducer to rotate, and connects the disc shaft One end surface is fixedly connected with the disc toothed cutter through bolts, the connecting disc shaft runs through the bearing and connects with the output end of the reducer, the connecting disc shaft passes through the central hole of the disc toothed cutter, and the bearing is fixed on the balance beam set on the frame.

In the disc-toothed cutter-type tree transplanting excavator, one end of the double-acting rotary oil cylinder is fixed on the trolley chassis, and the other end is fixedly connected to the platform.

The disc-toothed cutter type tree transplanting excavator is described, and the disc-toothed cutter is crescent-shaped.

The disc-toothed cutter-type tree transplanting excavator includes: when the disc-toothed cutter cuts off the lateral roots of trees, the included angle with the horizontal line on the ground is 80-90 degrees, and the angle between the main root of the tree and the horizontal line on the ground is cut off. 10 ~ 40 degrees setting.

Compared with the prior art, the present invention has the following advantages.

1. Driven by power, the disc-toothed cutter rotates to cut off the lateral roots of trees. The angle between the disc-toothed cutter and the ground level is 80 degrees. The rotating cutter can spin out the soil at the incision, just like a manual shovel Excavation is the same, as the trolley rotates, the lateral roots in the circumferential direction are cut off, and more fibrous roots are retained, the double-acting rotary cylinder is activated, and the angle between the disc-toothed cutter and the ground level is 15 degrees, and the roots are cut off in the circumferential direction The main root of the tree is toppled over, which is more efficient than the shovel driven by the existing oil cylinder, energy-saving 100%, and high in efficiency.

2. The double-acting lifting oil cylinder is installed on the base to lift the entire frame. When working, the oil cylinder is lowered, and in the transportation state, the oil cylinder is raised. It is easy to operate, simple and reliable.

3. The disc-toothed cutter can be replaced according to the size of the excavated tree.

4. The tree transplanting excavator adopts a high-manganese steel disc-toothed rotary cutter. The disc-toothed cutter rotates to cut roots and saves labor. The crescent-shaped disc-toothed cutter spins out the soil at the cutting point, which is wear-resistant and durable. .
