Abstract
The utility model discloses a circular saw blade provided with multi-fixing holes, the circular saw blade is provide with a circular saw blade body and a central fixing hole, and is characterized in that a plurality of pairs of auxiliary fixing holes (21, 22, 23, 24) are arranged surrounding the central fixing hole (2) of the circular saw blade body (1), each pair of the auxiliary fixing hole is arranged at the both sides of the central fixing hole, the two holes have the equal distance from the central fixing hole and are in the same diameter line with the central fixing hole, every pair of the auxiliary fixing hole is uniformly distributed. The circular saw blade in the utility model is suitable for various cutting saw blades, particularly for corn harvesters, and has the characteristics of simple and practical structure and allowing the conventional circular saw blade to be more firm in fixing, more stable in running, better in process quality, longer in service life time.
Description
Technical field
The utility model relates to a kind of agricultural machinery harvesting saw blade, specifically is a kind of saw blade, and particularly a kind of a plurality of fixing holes and number of teeth of being provided be at 70 to 160 teeth, use more stable, the good effect of cutting efficiency height, long service life.More durable saw blade.
Background technology
The saw blade that is used to cut uses very extensive, and its great majority is in the middle of disk a centre bore to be set, and is used for fixing saw blade.Some shortcoming of this structure: have only a center hole to fix, only fix by the fixture of centre bore both sides and the friction between the saw blade, such one is fixing not firm, skids easily; The 2nd, saw blade is in operation, and particularly at a high speed, or the saw blade diameter is when big, and the saw blade steadiness is poor, makes crudy influenced, and saw blade is damaged, and influences saw blade service life.Therefore, need make improvements.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of many fixing holes saw blade, and this saw blade makes saw blade fixing more firm by a plurality of auxiliary fixing holes are set, and moves more surely, and the life-span is longer.
The purpose of this utility model is achieved through the following technical solutions: many fixing holes saw blade, be provided with the annular saw lamellar body, the center fixation hole, it is characterized in that: around the center fixation hole of described annular saw lamellar body, be provided with several auxiliary fixing hole, these are several in the auxiliary fixing hole, every pair of auxiliary fixing hole all is located at the both sides in described center fixation hole respectively, two Kong Junyu center fixation holes are equidistant, and with the center fixation hole on same diameter line, described several to auxiliary fixing hole to and between evenly distribute.
The utility model further improves and the additional project of enforcement is:
Described several to auxiliary fixing hole to and between equidistantly on same circumference evenly distribute.
Described several to auxiliary fixing hole to between on different circumference, evenly distribute.
Be provided with diameter and described shop in the both sides of described annular saw lamellar body and help every pair of fixed disk that Kongzui major diameter distance is complementary in the fixing hole group.
The quantity of auxiliary fixing hole of the present utility model and position can be according to the sizes of saw blade, the size of operation rotary speed is provided with, saw blade is big more, rotary speed is fast more, then the quantity of auxiliary fixing hole is many more, and big more with the distance of centre bore, auxiliary fixing hole can be located on the concentric circles of a centre bore, also can be located on the concentric circles of different centre bores, be provided with flexibly.The utlity model has simple in structure be suitable for, can make traditional saw blade fixing more firm, move more stablely, crudy is better, the advantage of longer service life.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 of the present utility model;
Fig. 2 is the structural representation of embodiment 2 of the present utility model.
The profile of the utility model product is not subjected to the restriction of this figure, and only the profile change also belongs to protection domain of the present utility model.
Embodiment
The utility model is done the explanation of into going up the step below in conjunction with drawings and Examples: embodiment 1: referring to accompanying drawing 1, many fixing holes saw blade 1, be provided with the annular saw lamellar body, center fixation hole 2, around the center fixation hole of described annular saw lamellar body, be provided with 1 pair of auxiliary fixing hole 21, should be located at the both sides in described center fixation hole to auxiliary fixing hole, equidistant with the center fixation hole, and with the center fixation hole on same diameter line.
Embodiment 2: referring to accompanying drawing 2, many fixing holes saw blade, be provided with the annular saw lamellar body, the center fixation hole, be provided with 4 pairs of auxiliary fixing holes 21,22,23,24 around the center fixation hole 2 of described annular saw lamellar body 1, in the auxiliary fixing hole of this 4 couple, every pair of auxiliary fixing hole all is located at the both sides in described center fixation hole, equidistant with the center fixation hole, and with the center fixation hole on same diameter line.Be evenly distributed on the circumference between every pair of auxiliary fixing hole.
Below only be 2 embodiments of this patent; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of this patent.
Claims (4)
1. fixing hole saw blade more than a kind, be provided with the annular saw lamellar body, the center fixation hole, it is characterized in that: be provided with several on every side in the center fixation hole (2) of described annular saw lamellar body (1) auxiliary fixing hole (21,22,23,24), these are several, and every pair of auxiliary fixing hole all is located at the both sides in described center fixation hole respectively in the auxiliary fixing hole, and two Kong Junyu center fixation holes are equidistant, and with the center fixation hole on same diameter line, described several to auxiliary fixing hole to and between evenly distribute.
