Description

Novel earthing-up knife

Technical Field

The invention relates to the technical field of agricultural mechanical equipment, in particular to a novel hilling knife.

Background

When the field managing machine in the prior art carries out ridging operation, the soil turned up by the ridging knife is different in size, and some soil is connected together with one another or with grass or roots, so that the later ridging operation is not facilitated.

Disclosure of Invention

In order to solve the defects and problems of a field management machine in the prior art, a novel hilling knife is provided.

The technical scheme adopted by the invention for solving the technical problem is as follows: the novel hilling knife comprises a rotary knife shaft, five knife sleeves are fixed at the outer end of the rotary knife shaft, five rotary knives are fixed on the five knife sleeves through nuts, the rotary knives gradually become wider from a knife handle to a knife tip, the knife tip is upwards tilted, the tilting angle of the knife tip is 30-45 degrees, a knife tongue is transversely welded at the joint of the knife tip and the knife handle, the knife tongue is obliquely upwards tilted, the tilting angle of the knife tongue is 15-30 degrees, a bent knife notch is connected between the knife tongue and the knife handle, and a knife notch is formed among the bent knife notch, the knife tongue and the knife handle.

The invention has the beneficial effects that: compared with the prior art, the novel hilling knife has the advantages that the tip tilting angle is 30-45 degrees, the blade tongue tilting angle is 15-30 degrees, the hilling efficiency and the earth throwing precision can be greatly improved by adopting the angle, the cut of the bent knife is connected between the blade tongue and the knife handle, the raised soil can be effectively cut off and broken, grass or roots can be cut off, and the hilling quality is improved.

Drawings

The novel earthing-up knife of the present invention is further described with reference to the accompanying drawings and the detailed description.

Fig. 1 is a schematic perspective view of a novel hilling knife according to the present invention.

The specific implementation mode is as follows:

as shown in fig. 1, the novel hilling knife of the invention comprises a rotary knife shaft 1, five knife sleeves 2 are fixed at the outer end of the rotary knife shaft 1, and five rotary knives 4 are fixed on the five knife sleeves 2 through nuts 3.

As shown in fig. 1, the rotary knife 4 includes a knife root 41, a knife handle 42, a knife tip 43, a knife tongue 44, and a curved knife cut 45. The knife root 41 is sleeved in the knife sleeve 2 and fixedly connected through the nut 3, so that the rotary knife 4 and the knife sleeve 2 are fixed together. The rotary knife 4 becomes gradually wider from the handle 42 to the point 43. The tool nose 43 is tilted upwards, the tilting angle of the tool nose 43 is 30-45 degrees, the tool tongue 44 is welded at the joint position of the tool nose 43 and the tool handle 42, the tool tongue 44 is in the transverse direction, the tool tongue 44 is tilted upwards, and the tilting angle of the tool tongue 44 is 15-30 degrees.

As shown in FIG. 1, a curved blade cut 45 is connected between the blade tongue 44 and the handle 42, the curved blade cut 45 spans between the blade tongue 44 and the handle 42, and a blade opening 46 is formed between the curved blade cut 45 and the blade tongue 44 and the handle 42. The curved blade cuts 45 can effectively cut or chop the soil from the raised blade tongue 44, while the blades 46 can effectively cut the roots or grass.

In conclusion, compared with the prior art, the novel hilling knife has the advantages that the tip tilting angle is 30-45 degrees, the blade tongue tilting angle is 15-30 degrees, the hilling efficiency and the soil throwing precision can be greatly improved by adopting the angle, the cut of the bent knife is connected between the blade tongue and the knife handle, the raised soil can be effectively cut off and broken, grass or roots can be cut off, and the hilling quality is improved.

The present invention has been described in accordance with embodiments thereof with the understanding that the present invention is not limited thereto but rather it is to be understood that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims, and any such modifications, equivalents and the like as fall within the true spirit and scope of the invention.
