Abstract
The utility model provides a paddy field straw-returning cutter, which belongs to a part for agricultural machinery. The utility model overcomes the defects of the paddy field straw-returning cutter used in the prior art, i.e. high operation load, poor operation effect and poor economical efficiency. The paddy field straw-returning cutter mainly comprises a longitudinal curved cutter, a left horizontal wedged cutter and a right horizontal wedged cutter; the left horizontal wedged cutter and the right horizontal wedged cutter are respectively welded on the longitudinal curved cutter; the curvature radius of the longitudinal curved cutter is 100 to 110 millimeters; and both the welding angle between the left horizontal wedged cutter and the longitudinal curved cutter and the welding angle between the right horizontal wedged cutter and the longitudinal curved cutter are 55 to 85 degrees in the front view, 155 to 169 degrees in the side view and 140 to 172 degrees in the upward view. The paddy field straw-returning cutter is mainly used on various rotary cultivators.
Description
Technical field
The utility model belongs to a kind of parts of agricultural machinery, specifically, relates in particular to also field cutter of a kind of paddy field balloonflower root.
Background technology
Paddy rice is one of staple food crop of China, in recent years, ripe or rice, rice two ripe and three cultivated land districts at paddy and wheat two, the effective rate of utilization of rice wheat balloonflower root sharply descends.Therefore, rice wheat balloonflower root and the high-stubble shed behind the combine operation directly have influence on the plantation of paddy rice, thereby part rice wheat balloonflower root is gone out of use or burn, and have caused the wasting of resources and environmental pollution, have had a strong impact on people's lives and traffic safety.
At present, use also field cutter of paddy field balloonflower root, exist problems such as working load is big, operation effectiveness is poor, less economical in China.
Summary of the invention
In order to solve also field cutter of the paddy field balloonflower root that uses in the prior art, working load is big, poor, the less economical defective of operation effectiveness, and the utility model provides also field cutter of a kind of paddy field balloonflower root.
The utility model is realized through following technical scheme:
A kind of paddy field balloonflower root is the field cutter also, comprises vertical curved knife, the horizontal oblique cutter in a left side, right horizontal oblique cutter, and the horizontal oblique cutter in a left side is welded on respectively on vertical curved knife with right horizontal oblique cutter; Vertically the radius of curvature R of curved knife is the 100--110 millimeter; The horizontal oblique cutter in a left side is 55 °～85 ° with vertical curved knife at positive apparent direction soldering angle a with right horizontal oblique cutter, is 155 °～169 ° at side-looking direction soldering angle b, is 140 °～172 ° looking up direction soldering angle c.
Vertically the radius of curvature R of curved knife is preferably 105 millimeters.
Compared with prior art, the beneficial effect of the utility model is: use the also field cutter operation of paddy field balloonflower root, can reduce the power consumption of tractor; Improve the facility operating efficiency, improve balloonflower root and bury effect, help balloonflower root and accelerate the speed of rotting; Improve soil organic matter content, strengthen soil fertility, reduce fertilizer amount; Increase crop yield, increase farmers' income, and can avoid burning environmental pollution and the traffic safety problem of being brought because of balloonflower root.

Fig. 3 is that the A of Fig. 2 is to view.
Vertical curved knife in the drawings, 1; 2, the horizontal oblique cutter in a left side; 3, right horizontal oblique cutter.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment 1: a kind of paddy field balloonflower root is the field cutter also, comprises the horizontal oblique cutter of vertical curved knife 1, a left side 2, right horizontal oblique cutter 3, and the horizontal oblique cutter 2 in a left side is welded on respectively on vertical curved knife 1 with right horizontal oblique cutter 3; Vertically the radius of curvature R of curved knife 1 is 100 millimeters; The horizontal oblique cutter 2 in a left side and right horizontal oblique cutter 3 and vertical curved knife 1 are 55 ° at positive apparent direction soldering angle a, and b is 155 ° at side-looking direction soldering angle, is 140 ° looking up direction soldering angle c.
Embodiment 2: vertically the radius of curvature R of curved knife 1 is 105 millimeters, and other is identical with embodiment 1.
Embodiment 3: the horizontal oblique cutter 2 in a left side is 70 ° with vertical curved knife 1 at positive apparent direction soldering angle a with right horizontal oblique cutter 3, and b is 160 ° at side-looking direction soldering angle, is 160 ° looking up direction soldering angle c, and other is identical with embodiment 2.
The utility model can be docked on the existing all kinds of rotary tiller shaft in use, and is easy to install.Balloonflower root and high-stubble that combine is shed discharged water the soaked field after 24 hours; With the balloonflower root also facility of the field cutter operation of going to the field in paddy field is housed; Under the rotation of cutter shaft; Paddy field balloonflower root also field cutter is pressed grass, hack, covering balloonflower root and flow chart such as level land, thereby realizes flow charts such as balloonflower root is buried, whole ground.
