Description

A kind of stubble-cleaning knife

Technical field

The utility model is related to agricultural machinery technological field, more particularly to a kind of stubble-cleaning knife.

Background technology

At present, stubble cleaner is the special crop root residue for removing and being left after harvesting in the ground, and existing stubble-cleaning knife is with machinery Straw and root are smashed during moving ahead, straw-returning is allowed, still, existing stubble-cleaning knife runs into thicker when cutting stalk Be difficult to during strong stalk by straw cutting, or, when plant roots and stems are deeper, stubble-cleaning knife deeply in soil when, blade and ground into Right angle buries, and blade attacks soil rubble directly, all the time in blunt knife state, smashes rhizome without being difficult to bury, and blade is not Sharp state can be repaired into automatically, therefore, these problems existed for existing stubble-cleaning knife, research is a kind of to improve stubble-cleaning knife Cutting dynamics, and plant roots and stems preferably can be dug out into cut-out, and the blade for cutting rhizome can be repaired into sharp state automatically Stubble-cleaning knife, have important practical significance.

Utility model content

The purpose of this utility model is the deficiency existed for current stubble-cleaning knife, and design is a kind of to improve cutting for stubble-cleaning knife Dynamics is cut, and plant roots and stems preferably can be dug out into cut-out, and the blade for cutting rhizome can be repaired into sharp state automatically Stubble-cleaning knife.

The technical solution of the utility model is：A kind of stubble-cleaning knife, including handle of a knife, blade, loosen the soil plate, the handle of a knife, blade, The plate that loosens the soil is integrally formed, and the handle of a knife and blade are L-shaped, the plate that loosens the soil distorted downwards along transition wire with respect to blade 20 °~ 60 °, the transition wire has 10 °~20 ° angles with the blade base, and the blade is provided with serrated knife blade, described to loosen the soil Plate end is provided with some knives that loosen the soil, and the knife end of loosening the soil is provided with smooth blade, the blade along blade length provided with some Reinforcement.

Further, the handle of a knife is provided with installation through-hole.

The beneficial effects of the utility model are：

Blade of the present utility model is provided with serrated knife blade, working resistance can be reduced when cutting stalk, and then reduce Tractive resistance, saving fuel oil improves efficiency, reduces production cost；The plate that loosens the soil distorted downwards along transition wire with respect to blade 20 °~ 60 °, it is to avoid blade buries at a right angle with ground, soil rubble is attacked directly due to blade and causes blade blunt knife, and will preferably can be planted Thing rhizome digs out cut-out, and the blade for cutting rhizome can be repaired into sharp state automatically, raises labour efficiency.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Wherein：

1st, handle of a knife 2, blade 3, loosen the soil plate

4th, transition wire 5, serrated knife blade 6, loosen the soil knife

7th, smooth blade 8, reinforcement 9, installation through-hole

Embodiment

Brief description is made to embodiment of the present utility model below in conjunction with the accompanying drawings.

A kind of stubble-cleaning knife as shown in Figure 1, including handle of a knife 1, blade 2, loosen the soil plate 3, the handle of a knife 1, blade 2, loosen the soil plate 3 one Body formed, the handle of a knife 1 and blade 2 are L-shaped, and the plate 3 that loosens the soil distorts downwards 20 °~60 ° with respect to blade 2 along transition wire 4, Avoid blade from being buried at a right angle with ground, soil rubble is attacked directly due to blade and causes blade blunt knife, the transition wire 4 and the knife The base of body 2 has 10 °~20 ° angles, and the blade 2 is provided with serrated knife blade 5, and work resistance can be reduced when cutting stalk Power, and then tractive resistance is reduced, saving fuel oil improves efficiency, reduces production cost, if the end of plate 3 of loosening the soil is provided with dry and soft Plant roots and stems preferably can be dug out cut-out by native knife 6, the end of knife 6 of loosening the soil provided with smooth blade 7, and can will cut root The blade of stem repairs into sharp state automatically, raises labour efficiency, and some reinforcements are provided with along the length of blade 2 on the blade 2 8, it is to avoid blade is broken in operation process, extend stubble-cleaning knife service life, the handle of a knife 1 is provided with installation through-hole 9, for inciting somebody to action Stubble-cleaning knife is installed on stubble ploughing knife pivot.

One embodiment of the present utility model is described in detail above, but the content is only of the present utility model Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
