Description

a tree root digging machine

technical field

The invention relates to the technical field of machinery, in particular to a machine for felling tree roots.

Background technique

Poplar is the main species of timber forest, shelter forest and surrounding greening. Planting poplars not only has huge economic benefits, but also has great ecological and social benefits. Poplar grows fast and produces a large amount of wood. Generally, it can be harvested and utilized in about 10 years. After the poplar trees are felled, they will leave a large number of root systems in the woodland. If it is necessary to replant or change the land use, it is necessary to remove the cut roots. Compared with other forest trees, the root system of poplar is not well developed, and the problem of one-time uprooting during harvesting can be considered.

There are mainly two kinds of existing technologies for removing the roots of fast-growing forests. One is to use a traditional excavator to dig the tree. This method cannot achieve the purpose of uprooting the roots at one time, and it is not efficient to dig the soil one bucket at a time. Another kind is as patent CN201420418054, and this technology is improved on the model of former excavator, just changes the excavating bucket into the mechanism of grasping root, and this mechanism of grasping root grasps tree root earlier during work, then passes through top The root of the tree is pulled up by the way of pulling, and the efficiency is improved. And the common shortcoming of above two kinds of prior art is: excavator itself price is very high, is not suitable for common grower to use.

Contents of the invention

The purpose of this invention is to provide a kind of root digging machine that can be used together with 50 horsepower four-wheel tractors. The tree root digging machine can uproot tree roots at one time, and has high working efficiency. Since 50-horsepower four-wheel tractors are currently widely used in rural areas and have a large number of stocks, the tree root digging machine is used in conjunction with 50-horsepower four-wheel tractors to reduce input costs and improve economic benefits.

The technical solution adopted in the present invention is: a tree root digging machine, which is used together with a 50-horsepower four-wheel tractor, and its components include a fuel tank, a hydraulic console, a tree root digging machine base, an upper hydraulic cylinder, a lower hydraulic cylinder, a Side bars, right side bars, cross braces, connecting rods and digging forks, the fuel tank is fixedly connected with the tractor front end counterweight connecting plate. The hydraulic console is fixedly connected with the bracket near the driver's seat. The base of the tree root digging machine is fixedly connected to one end of the tractor gearbox; three pairs of connecting ears are arranged on one side of the connecting plate of the root digging machine base, which are divided into one upper and two lower left and right symmetrical configurations, wherein the upper connecting ear and the upper hydraulic pressure One end of the cylinder is swivel connected, the lower connecting lug is spherically connected with one end of the lower hydraulic cylinder; the piston end of the upper hydraulic cylinder is swivelly connected with the connecting lug of the cross brace, and the piston end of the lower hydraulic cylinder is connected spherically with the connecting ear of the connecting rod; The two ends of the strut are respectively fixedly connected with the left and right side rods; one end of the left and right side rods is respectively connected with the connection pins on both sides of the connecting rod in rotation, and the other end is respectively connected with the tie rod pins on both sides of the tractor in rotation. The cross brace is provided with a pair of connecting ears on the middle symmetrical plane. The connecting rod is a [shaped symmetrical structure, with a pair of connecting ears at its two ends, a connecting pin at its two outer corners, and four digging forks arranged side by side at intervals and fixedly connected in its middle section. All components form a composite four-bar linkage.

Operation process: drive the tractor and operate the hydraulic system. In the first step, the piston rod of the upper hydraulic cylinder shrinks, and the piston rods of the two lower hydraulic cylinders extend synchronously, so that the digging fork leaves the ground and is basically perpendicular to the ground. Drive the tractor to the root digging position; in the second step, the piston rod of the upper hydraulic cylinder is extended, so that the digging fork is pressed down to the depth of the tree root; in the third step, the piston rods of the two lower hydraulic cylinders are retracted synchronously, so that the digging fork pries the tree root In the fourth step, the piston rod of the upper hydraulic cylinder shrinks to pull the entire tree root off the ground.

Implementation of the above technical solutions can achieve the purpose of the present invention.

The present invention has the advantages of: ① the tree roots can be dug up at one time, and the working efficiency is high; ② the present invention is used together with a 50-horsepower four-wheel tractor, and the cost is low. However, 50-horsepower four-wheel tractors are widely used in the rural areas of our country at present, and can be fully utilized to improve economic benefits.
