Abstract
The utility model discloses a special digging cutter for a Chinese yam harvester. The special digging cutter comprises a cutter body. The cutter body is arranged on a digging chain of the Chinese yam harvester and is provided with an arc cutting head, a head end of the arc cutting head is provided with a blade, the blade comprises a circumscribed-circle blade part and an inscribed-circle blade part, the circumscribed-circle blade part is arranged on an outer side surface of an arc bulge at the head end of the arc cutting head, and the inscribed-circle blade part is arranged on an inner side surface of the arc bulge at the head end of the arc cutting head. According to the special digging cutter disclosed by the utility model, the arc cutting head is arranged on the cutter body so that a contact area between the cutter head and soil is increased, and the blade at the edge of the cutter head comprises the circumscribed-circle blade part on an arc convex surface and the inscribed-circle blade part on an arc concave surface so that a contact surface of the digging cutter with the soil is gradually thickened, thus the resistance of the digging cutter entering the interior of the soil is reduced, and the efficiency of digging is favorably improved.
Description
Technical field
The utility model relates to a kind of cutter, relates in particular to a kind of excavation cutter that is applicable to results long-rhizome crop.
Background technology
The cutter that uses on the isometric root crop reaping machine of Chinese yam at present generally comprises cutter hub and the cutter head that is attached thereto; And in order to improve the efficient of digging, cutter head is designed to arcuate structure, and blade symmetry be arranged on the cutter head both sides of edges; But blade only is arranged on the curved edge of cutter head mostly; Make that thickness increases suddenly on the arcwall face of junction and cutter head of arc and cutter hub, increased the resistance that cutter buries, reduced the efficient of digging to a certain extent.
The utility model content
The utility model technical problem to be solved provides a kind of simple in structure, can improve the special-purpose cutter that excavates of Chinese yam harvester of digging efficiency.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the special-purpose cutter that excavates of Chinese yam harvester; Comprise that being installed on said Chinese yam harvester excavates the cutter hub on the chain; Said cutter hub is provided with the arc cutter head, and said cutter head head end is provided with blade, and said blade comprises the circumcircle blade part of being located at said cutter head head end arc outer surface and the inscribed circle blade part of being located at said cutter head head end arc inner surface.
As optimized technical scheme, said inscribed circle blade part extends to the junction of said cutter head and said cutter hub along said cutter head head end arc convex inner surface.
As optimized technical scheme, the internal diameter of said cutter head arc is caudad dwindled by the cutter head head end gradually.
As optimized technical scheme, said circumcircle blade part and said inscribed circle blade part are positioned at said cutter head head end end and intersect.
Owing to adopted technique scheme; The special-purpose cutter that excavates of Chinese yam harvester is provided with the arc cutter head on cutter hub; The arc cutter head has increased the contact area of cutter head and soil, and blade comprises the circumcircle blade part and the inscribed circle blade part of being located at said cutter head head end arc convex inner surface of cutter head head end arc convex outer surface, makes excavation cutter and soil contact thickening gradually; Resistance when getting into soil inside to reduce excavating cutter helps to improve the efficient of digging.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the opposite side view of Fig. 1;
Among the figure: the 1-cutter hub; The 2-cutter head; 3-circumcircle blade part; 4-inscribed circle blade part.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
Shown in Fig. 1, Fig. 2 and Fig. 3 were common, the special-purpose cutter that excavates of Chinese yam harvester comprised that being installed on said Chinese yam harvester excavates the cutter hub 1 on the chain; Said cutter hub 1 is provided with arc cutter head 2; The internal diameter of said cutter head 2 arcs is caudad dwindled by cutter head 2 head ends gradually, and cutter head 2 is set to arcuate structure, has increased the contact area of cutter head 2 with soil; And during 1 motion of the digger chain band moving knife body of Chinese yam harvester; Can make the cambered surface recess of cutter head 2 stir a large amount of soil, simultaneously it moved to more than the face of land, help being unearthed of Chinese yam.
Said cutter head 2 edges are provided with blade; Said blade comprises the circumcircle blade part 3 and the inscribed circle blade part 4 of being located at said cutter head 2 head end arc inner surfaces of said cutter head 2 head end arc outer surfaces; And said circumcircle blade part 3 is positioned at said cutter head 2 head end ends with 4 ones of said inscribed circle blades and intersects; Circumcircle blade part 3 makes cutter head 2 surface thicknesses present the state of gradual change with inscribed circle blade part 4, can reduce to a certain extent that cutter buries and the resistance when being unearthed.
Specifically being distributed as of present embodiment blade: said circumcircle blade part 3 is arranged on the curved surfaces of said cutter head 2 convexities, and said inscribed circle blade part 4 extends to the junction of said cutter head 2 and said cutter hub 1 along said cutter head 2 head end arc convex inner surfaces.Make the cutter hub 1 and the thickness of the junction of cutter head 2 that progressive formation arranged, can reduce resistance and improve the efficient that Chinese yam is unearthed.
The utility model not only can be installed on and be used to gather in the crops Chinese yam on the Chinese yam harvester, can also be installed on other results class mechanically, is used to gather in the crops other long-rhizome crop, and is simple in structure, easy to use.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
