Abstract
A kind of afforestation prevents trunk from cracking tool when cutting down trees, main component is two semicircular rings being made into steel plate, intermediate welding wire rope connects, it can be movable, trunk cracks in order to prevent when afforestation is cut down trees, first bark is pulled down in the root of tree, then this kit on trunk, bolt (5) are passed through into the circular hole on steel plate (4) and are then passed through the circular hole on movable steel plate (3), it is screwed on the nut on steel plate (3), it tightens, if the gap between trunk and two semicircular rings is too big, with regard to unclamping bolt (5), movable steel plate (3) is a little mobile to the left side, it screws on again again, in this way, it would not there is a phenomenon where trunks to crack when great Shu falls down.
Description
(1) technical field
The present invention relates to a kind of tool, it is green to belong to gardens for especially a kind of afforestation prevents trunk from cracking tool when cutting down trees
Change agriculture and forestry machinery equipment technical field.
(2) background technique
It is usually direction gasoline saw, electric saw or the hand first in a lateral edge for tree perpendicular to trunk when afforestation worker cuts down trees
Saw saw twice, forms the opening of a V-arrangement, depth meets and exceeds the axle center of trunk, then in the other side of trunk, along level
Direction is gone down to the center of opposite side v-shaped opening saw, when soon cutting the center of opposite side v-shaped opening, due to setting itself greatly
The reason of weight, big tree can fall down towards to side direction automatically；If the weight of tree crown is sufficiently large, big tree can not also have in two openings
Have perforation before begin to, and can by trunk from the position close to axle center along the axial direction of trunk tear together very it is long not
The openning of rule, seriously destroys the globality of trunk, substantially reduces the use value of trunk and the market price, do not have also at present
There is a kind of simple and effective tool that can prevent trunk from cracking when cutting down trees.
(3) summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides be specifically used to prevent trunk from cracking when a kind of afforestation is cut down trees
Tool.
The present invention is achieved by the following scheme:
The tool that a kind of afforestation of the present invention prevents trunk from cracking when cutting down trees, main component is two semicircles being made into steel plate
Ring, centre are connected with wirerope, can be movable, and after the semicircle packet that two are made into steel plate is on trunk, both ends are used
Bolt is tightened, and trunk cracks when for preventing from setting greatly.
The beneficial effects of the present invention are: structure is simple, easy to carry, kit can make on the big tree of different-diameter
With.
(4) Detailed description of the invention
Attached drawing is the structural schematic diagram for the tool for preventing trunk from cracking when a kind of afforestation of the present invention is cut down trees.
Wherein: 1 semicircular ring A, 2 nuts, 3 movable steel plates, 4 steel plates, 5 bolts, 6 semicircular ring B, 7 wirerope.
(5) specific embodiment
A kind of specific embodiment for the tool for preventing trunk from cracking when cutting down trees as shown in the picture for a kind of afforestation of the present invention.Packet
Include: semicircular ring A(1), nut (2), movable steel plate (3), steel plate (4), bolt (5), semicircular ring B(6), wirerope (7).
Wherein: movable steel plate (3) processes a slot on one side, and a circular hole, the left side weldering of circular hole are bored in another side
Connect a nut (2), semicircular ring A(1) it is to be process with steel plate, thickness is than the slot on movable steel plate (3)
Width is 0.5 millimeter small, slide movable steel plate (3) only could when perpendicular to semicircular ring A(1), semicircular ring A(1) one end weldering
Upper three wirerope (7) connect with semicircular ring B(6)；The other end is processed into zigzag in outside, and outermost end is processed into wedge
Shape, when movable steel plate (3) is located at semicircular ring A(1) sawtooth position when pull will not move to the right；Semicircular ring B(6) it is to use steel plate
It is process, thickness is identical as semicircular ring A(1), and one end and three wirerope (7) firm weldings make itself and semicircular ring A(1)
It connects, the other end is welded with steel plate (4), there is circular hole on steel plate (4), and bolt (5) passes through this circular hole and is then passed through movable steel plate (3)
On circular hole, can be screwed on the nut on steel plate (3), the diameter of three wirerope (7) is identical with length.
Trunk cracks in order to prevent when afforestation is cut down trees, and first bark is pulled down in the root of tree, then the present invention one
Bolt (5) are passed through circular hole on steel plate (4) and worn again by the kit that kind afforestation prevents trunk from cracking when cutting down trees on trunk
The circular hole on movable steel plate (3) is crossed, is screwed on the nut on steel plate (3), tightens, if between trunk and two semicircular rings
Gap is too big, just unclamps bolt (5), and movable steel plate (3) is a little mobile to the left side, then screws on again.In this way, fall down in great Shu
When would not there is a phenomenon where trunks to crack.
