Description

A kind of device that cuts off auxiliary roots of wheat

Technical field

The invention belongs to agricultural mechanical field, be specifically related to a kind of winter wheat device that preceding or period of seedling establishment cuts off its axillary root of surviving the winter.

Background technology

Wheat is one of China's important crops, and along with constantly reduce in the raising and the arable land of living standards of the people, it is more and more important that the status of good quality and high output wheat becomes.The wheat researcher finds in the production practices of research improving yield of wheat: the axillary root of early stage an amount of excision or damage wheat, the not only not underproduction of wheat has the output positive-effect on the contrary.This is because intertillage is completely cured root system to be had short control effect.The part root system that winter wheat is completely cured and has damaged plant seedling stage, promptly at that time inhibitory action was played in the growth of its root amount and root, but after being completely cured, through jointing---the vigorous growth of blooming, the adnation radical of the wheat plant of being completely cured and total root are heavy on the contrary above the adjoining tree of not being completely cured.The old root of being completely cured sprays new root, takes root effect deeply, promote wheat root to grow, enlarge the distribution of root system in soil, increased absorption inorganic nutriment, also improve the vigor in residue root system later stage, particularly improved the vigor of deep layer root system, delayed the aging of root system.Simultaneously, can also obviously delay the wheat senescence of leaves, improve the photosynthesis characteristics in wheat later stage, improve photosynthetic rate, be the important adjusting measure that improves wheat late growth stage function, prevents early ageing.Be completely cured also to have to control and tiller and colony, the raising percentage of earbearing tiller, promote short effect that weighs of big panicle many grains per panicle and anti-early ageing, effect of increasing production is very remarkable.The outfitting tool but the intertillage that does not still suit large area to popularize at present is completely cured makes this technology be difficult to large scale application.

Summary of the invention

At problem and defective in existing in the above-mentioned prior art, the objective of the invention is to provide a kind of device that cuts off auxiliary roots of wheat, this device can cut off two row wheat part axillary roots in the ranks, also plays the effect of weeding, chesson simultaneously.

In order to reach the technical scheme that purpose of the present invention takes be: a kind of device that cuts off auxiliary roots of wheat, it comprises spade, it is characterized in that, bottom is connected with spear at spade, the spear top is equipped with front cutting edge, and bottom is equipped with rear knife edge, and front cutting edge and rear knife edge are perpendicular to same straight line.

Described spear is pointed shape arrow shovel, and its clearance angle ε that buries is 7 °～10 °, and basil i is 12 °～15 °, and cutting angle β is 19 °～25 °, and penetrating angle α is 6 °～10 °, and open angle 2 γ are 25 °～40 °.

Described front cutting edge is installed in the cutter groove of spear by inner bolt.

The knife edge of described front cutting edge and the penetrating angle of horizontal plane are 30 °～60 °.

Described rear knife edge is semicircle, is installed in by bolt in the cutter groove of spear bottom.

Front cutting edge of the present invention and rear knife edge installation direction are perpendicular to horizontal plane and consistent with direction of advance, and two blades are installed in the same plane.

This cut-out auxiliary roots of wheat device is installed on the wheat root-cutting machine, can adjust this Unit Installation position according to the size of wheat line-spacing, root-cutting machine is in the process of advancing, this device is operated in two row wheats in the ranks, this installs each blade and wheat part axillary root in the ranks can be cut off, and can also play the effect of intertill and clean tillage and chesson simultaneously.

The device of cut-out auxiliary roots of wheat of the present invention, because the spear reasonable in design, the resistance of being completely cured of breaking ground is little, power consumption is little, can effectively cut off two row wheat part axillary roots in the ranks, front cutting edge and rear knife edge can further cut off the auxiliary roots of wheat of the upper and lower both sides of spear, and the auxiliary roots of wheat in the following 15cm in the face of land is cut off, the effect of being completely cured is obvious, play disconnected old root, spray new root, the effect of taking root deeply, finally make wheat big panicle many grains per panicle grain heavy, reach effect of increasing production.

The device of cut-out auxiliary roots of wheat of the present invention can also cut off the effect of playing weeding, chesson with grass roots in operation process.

Embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in detail.

Fig. 1 is the structural representation of the device of cut-out auxiliary roots of wheat of the present invention.A kind of device that cuts off auxiliary roots of wheat, it comprises spade 1, it is characterized in that, and 1 bottom is connected with spear 2 at spade, and spear 2 tops are equipped with front cutting edge 3, and bottom is equipped with rear knife edge 4, and front cutting edge 3 and rear knife edge 4 are perpendicular to same plane.The knife edge of front cutting edge (3) and the penetrating angle of horizontal plane are 30 °～60 °, and rear knife edge (4) is semicircle.Front cutting edge 3 and rear knife edge 4 arrive in the upper and lower cutter groove with bolt respectively, can dismantle easily after the wearing and tearing, change.

Fig. 2 and Fig. 3 are respectively the front view and the vertical view of spear 2.Spear 2 is pointed shape arrow shovel, and parameter mainly comprises the clearance angle ε that buries, basil i, and cutting angle β, penetrating angle α, open angle 2 γ etc., strong for guaranteeing the spear ability of burying, the amount of breaking ground is little, and power consumption is little, need be optimized each parameter.The clearance angle ε that buries of spear 2 is 7 °～10 °, and basil i is 12 °～15 °, and cutting angle β is 19 °～25 °, and penetrating angle α is 6 °～10 °, and open angle 2 γ are 25 °～40 °.

Fig. 4 and Fig. 5 are the structural representation of front cutting edge and rear knife edge.Front cutting edge and rear knife edge installation direction are perpendicular to horizontal plane and consistent with direction of advance, and two blades are installed in the same plane.

Front cutting edge has sharp blade, penetrating angle is 30 °～60 °, can directly cut off the axillary root on spear top, rear knife edge is semicircle, has sharp knife edges, can cut off the more auxiliary roots of wheat of deep layer, and little to the disturbance of soil, after the anterior wearing and tearing can before and after reversing of position, continue to use, after all wearing and tearing in the front and back end, change also very convenient.The two blades ability of being completely cured is strong, and the resistance of being completely cured of breaking ground is little, reduces power consumption.

The device of cut-out auxiliary roots of wheat of the present invention, because reasonable in design, the resistance of being completely cured of breaking ground is little, power consumption is little, walk between wheat two row, can effectively cut off the wheat part axillary root in 10～15cm under the face of land, front cutting edge and rear knife edge can further cut off the auxiliary roots of wheat of the upper and lower both sides of shovel of being completely cured, the effect of being completely cured is obvious, wheat root there is the effect of afterwards urging that presses down earlier, finally make the better of wheat root growth, promote the heavy effect of the short grain of big panicle many grains per panicle and anti-early ageing, and significantly improve output.This device also plays the effect of intertill and clean tillage and chesson simultaneously.
