Abstract

A kind of afforestation prevents trunk from cracking device when cutting down trees, main component is two semicircular rings being made into steel plate, centre is connected with connection ring, 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 present apparatus packet 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

A kind of afforestation prevents trunk from cracking device when cutting down trees
(1) technical field
The present invention relates to a kind of device, it is green to belong to gardens for especially a kind of afforestation prevents trunk from cracking device 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 device 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 Device.
The present invention is achieved by the following scheme:
The device 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 connection ring, 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, set of device can make on the big tree of different-diameter With.
(4) Detailed description of the invention
Attached drawing 1 is the structural schematic diagram for the device for preventing trunk from cracking when a kind of afforestation of the present invention is cut down trees.
Attached drawing 2 is the structural schematic diagram for the device connection ring for preventing trunk from cracking when a kind of afforestation of the present invention is cut down trees.
Attached drawing 3 is the structure before the device connection ring for preventing trunk from cracking when a kind of afforestation of the present invention is cut down trees is loaded onto Schematic diagram.
Wherein: 1 semicircular ring A, 2 nuts, 3 movable steel plates, 4 steel plates, 5 bolts, 6 semicircular ring B, 7 connection rings, 8 square hole A, 9 sides Hole B.
(5) specific embodiment
As attached drawing 1,2,3 show a kind of specific implementation for the device for preventing trunk from cracking when a kind of afforestation of the present invention is cut down trees Example.Include: semicircular ring A(1), nut (2), movable steel plate (3), steel plate (4), bolt (5), semicircular ring B(6), connection ring (7), Square hole A(8), square hole B(9).
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), and one end has a square hole A (8), the other end is processed into zigzag in outside, and outermost end processes wedgewise, when movable steel plate (3) is located at semicircular ring A(1) saw Pulling to the right when tooth position is set will not move;Semicircular ring B(6) it is to be process with steel plate, thickness is identical as semicircular ring A(1), There is a square hole A (9) in one end, and 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 Circular hole on movable steel plate (3) can be screwed on the nut (2) on steel plate (3), and connection ring (7) is the steel being processed into steel plate Item, enclose circle after pass through square hole A(8) and square hole B(9) after notch is welded, form a connection ring.
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 device packet 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.
