Embodiment 1

[0014] Example 1: A paddy field bellflower knife for returning to the field, including a longitudinal arc knife 1, a left transverse oblique knife 2, and a right transverse oblique knife 3, and the left transverse oblique knife 2 and the right transverse oblique knife 3 are respectively welded on the longitudinal On the arc knife 1; the radius of curvature R of the longitudinal arc knife 1 is 100 millimeters; the left transverse oblique knife 2 and the right transverse oblique knife 3 and the longitudinal arc knife 1 have a welding angle a of 55° in the front view direction, and The welding angle b in the side view direction is 155°, and the welding angle c in the bottom view direction is 140°.

Embodiment 2

[0015] Embodiment 2: The radius of curvature R of the longitudinal arc knife 1 is 105 mm, and the others are the same as in Embodiment 1.

Embodiment 3

[0016] Embodiment 3: The welding angle a of the left transverse oblique knife 2 and the right transverse oblique knife 3 and the longitudinal arc knife 1 is 70° in the front view direction, 160° in the side view direction b, and c in the bottom view direction Be 160 °, others are identical with embodiment 2.

[0017] When the invention is in use, it can be directly replaced on the cutter shafts of various existing rotary cultivators, and the installation and use are convenient. After soaking the straw and high stubble scattered by the combine harvester in water for 24 hours, the machine equipped with the platycodon grandiflorum returning knife is put into the field for operation. , covering straw and leveling the land and other operations, so as to realize the operation procedures such as straw burial and land preparation.

Abstract

The invention provides a rice field straw chopper, and belongs to a part of agricultural machinery. The rice field straw chopper overcomes the defects of high operation load, poor operation effect and poor economical efficiency of the rice field straw chopper used in the prior art. The rice field straw chopper mainly comprises a longitudinal arc knife, a left transverse oblique knife and a right transverse oblique knife, wherein the left transverse oblique knife and the right transverse oblique knife are welded on the longitudinal arc knife respectively; the curvature radius of the longitudinal arc knife is 100 to 110 millimeters; and the welding angles between the left transverse oblique knife and the longitudinal arc knife and between the right transverse oblique knife and the longitudinal arc knife are 55 to 85 degrees in the front view direction, 155 to 169 degrees in the side view direction and 140 to 172 degrees in the bottom view direction. The rice field straw chopper is mainly used for various rotary cultivators.

Description

technical field [0001] The invention belongs to a part of an agricultural machine, and in particular relates to a paddy field bellflower returning knife. Background technique [0002] Rice is one of the main food crops in my country. In recent years, in areas where rice and wheat are double-cropped or rice-rice double-cropped and triple-cropped, the effective utilization rate of rice and wheat straw has dropped sharply. Therefore, the rice straw and high stubble scattered after the combine harvester operation directly affect the planting of rice, so that part of the rice straw is discarded or burned, resulting in waste of resources and environmental pollution, seriously affecting people's lives and traffic safety . [0003] At present, the use of paddy field straw returning knives in our country has problems such as large operating load, poor operating effect, and poor economic efficiency. Contents of the invention [0004] In order to solve the defects of the paddy fiel...
