SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to lie in overcoming the above-mentioned that exists among the prior art, the utility model aims at providing a cutting knife, conveniently adjusts the interval between the cutting blade, need not to demolish cutting blade moreover.

In order to realize the technical effect, the utility model discloses a technical scheme does: the utility model provides a cutting knife, include the arbor, fixed and the equidistance distribute in a plurality of cutting blades on the arbor, cutting blade with the arbor sets up with one heart, and is adjacent be provided with interval adjustment mechanism between the cutting blade, interval adjustment mechanism including set up in the position sleeve of cutting blade both sides, every side the position sleeve all with cutting blade passes through a plurality of fasteners looks fixed connection, both sides be provided with nested between the position sleeve, nested with the setting is dismantled mutually to the arbor, the position sleeve cover is located on the arbor, just the position sleeve with be provided with radial limit structure between the arbor.

The further improvement is that: the nesting comprises a first sleeve body and a second sleeve body which are semicircular and mutually matched, and two ends of the first sleeve body are fixedly connected with the second sleeve body through a plurality of bolts respectively.

The further improvement is that: the fastener is a connecting bolt.

The further improvement is that: the radial limiting structure comprises a plurality of positioning convex strips arranged on one of the cutter shaft and the inner side wall of the positioning sleeve, and positioning grooves which are arranged on the other one of the cutter shaft and the inner side wall of the positioning sleeve and are matched with the positioning convex strips, the height of the positioning convex strips and the depth direction of the positioning grooves extend along the radial direction, and the length direction of the positioning convex strips and the length direction of the positioning grooves extend along the length direction of the cutter shaft.

The further improvement is that: the positioning convex strips are provided with a plurality of convex strips and are evenly arranged on the cutter shaft.

The further improvement is that: a connecting sleeve is arranged at one end of the positioning sleeve, the diameter of the connecting sleeve is larger than that of the positioning sleeve, a plurality of through holes are formed in the cutting blade, connecting holes matched with the through holes are formed in the connecting sleeve, and the fastening piece penetrates through the connecting holes and the through holes to fixedly connect the connecting sleeve with the cutting blade.

The utility model has the advantages and the beneficial effects that: cutting blade passes through the position sleeve cover and sets up on the arbor, and the nestification sets up between two adjacent cutting blade's position sleeve, and the setting is dismantled mutually with the arbor to nested moreover, can adjust adjacent cutting blade's interval through the installation or demolish the nestification and the different length of installation, and it is convenient to adjust, can not trompil the arbor moreover, has guaranteed its intensity and life.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, fig. 2 and fig. 3, a cutting knife includes arbor 1, fixed and equidistance distribution in a plurality of cutting blade 2 on the arbor 1, cutting blade 2 with arbor 1 sets up with one heart, and is adjacent be provided with interval adjustment mechanism between cutting blade 2, interval adjustment mechanism including set up in the position sleeve 3 of cutting blade 2 both sides, every side position sleeve 3 all with cutting blade 2 is through a plurality of fasteners 7 looks fixed connection, both sides be provided with nested 4 between the position sleeve 3, nested 4 with arbor 1 dismantles the setting mutually, position sleeve 3 overlaps and locates on the arbor 1, just position sleeve 3 with be provided with radial limit structure between the arbor 1.

The preferred embodiment in this embodiment does, nested 4 includes the first cover body and the second cover body that semicircular in shape and mutually supported, the both ends of the first cover body respectively with the second cover body is through a plurality of bolts looks fixed connection, because nested 4 does not contact with cutting blade 2, it only plays the axial positioning effect, consequently only need control its length can realize the interval between the adjacent cutting blade 2 and adjust, and need not to carry out radial positioning between nested 4 and the arbor 1, adopt the cooperation of the first cover body of two semicircular and the second cover body from this, dismouting and its convenience, in addition can also be the one end of the first cover body with the one end looks rotating connection of the second cover body, its other end passes through the bolt fastening, it is more convenient during the dismouting operation.

In a preferred embodiment of the present embodiment, the fastening member 7 is a connecting bolt.

Radial limit structure including set up in a plurality of location sand grip 5 on the arbor 1, set up in the locating sleeve 3 inboards of telling and with location sand grip 5 matched with constant head tank 6, location sand grip 5 high and the depth direction of constant head tank 6 is along radial extension, location sand grip 5 and the length direction of constant head tank 6 is along the length direction of arbor 1 extends, location sand grip 5 has a plurality of, and evenly set up in on the arbor 1.

The preferred embodiment in this embodiment does, an end of the positioning sleeve 3 is provided with a connecting sleeve 8, the diameter of the connecting sleeve 8 is greater than the diameter of the positioning sleeve 3, the cutting blade 2 is provided with a plurality of through holes, the connecting sleeve 8 is provided with a connecting hole matched with the through holes, the fastener 7 passes through the connecting hole and the through holes are used for fixedly connecting the connecting sleeve 8 with the cutting blade 2.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
