Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a tool apron 1 system of an anti-flail knife, which has the beneficial effects of preventing flail knife and being easy to replace as shown in fig. 1 to 4; the tool comprises a tool apron 1 connected with driving equipment such as excavating machinery and a tool bit 2 detachably mounted on the tool apron 1, wherein one end of the tool bit 2 is movably inserted into the tool apron 1, and the other end of the tool bit 2 is in contact with the outside, so that the tool bit has the characteristics of wear resistance, high strength and the like; the tool apron 1 is provided with a cotter pin 3 for axially limiting the tool bit 2, so that the tool bit 2 is prevented from being separated from the tool apron 1; the tool bit 2 rotates relative to the tool apron 1 under the action of external force. The cotter pin 3 may axially limit the cutter head 2, but does not prevent the cutter head 2 from rotating.
The end part of the tool bit 2, which is spliced with the tool apron 1, comprises a first splicing column 4 and a second splicing column 5 which are communicated with each other and have the same axle center; an annular groove 6 is formed in the first plug column 4; a first inserting hole 7 and a second inserting hole 8 are formed in the positions where the tool apron 1 and the tool bit 2 are inserted and matched; the diameter of the second plug hole 8 is smaller than that of the first plug hole 7; the first plug column 4 is positioned in the middle of the tool bit 2. Wherein the first plug column 4 is matched with the first plug hole 7, and the second plug column 5 is matched with the second plug hole 8.
The annular groove 6 can be arranged on the second plug column 5, and the annular groove 6 is mainly opposite to the pin hole 9 and matched with the split pin 3 to realize limiting.
The tool apron 1 is also provided with a pin hole 9; two pin holes 9 are arranged; the pin hole 9 penetrates through the whole tool apron 1 and is communicated with the first inserting hole 7; the cotter pin 3 is in interference fit with the pin hole 9; the cotter pin 3 can be taken out of the pin hole 9 under the action of sufficient external force, so that the cotter pin 3 is prevented from being separated from the pin hole 9 and the cutter head 2 is prevented from falling off due to vibration in the using process; the outer peripheral face in the middle of the cotter pin 3 is abutted to the annular groove 6 of the first plug column 4, namely, one part in the middle of the cotter pin 3 is matched with the annular groove 6, and the other part is matched with the pin hole 9, so that the axial direction of the first plug column 4 is limited.
The tool apron 1 at two ends of the pin hole 9 is provided with the abdicating notch 10, and the abdicating notch 10 can prevent the outside from rubbing the cotter pin 3 on the tool apron 1 to cause abrasion in the use process of the tool bit 2; the opening tracks of the two pin holes 9 are splayed.
Has the advantages that: the tool bit 2 plays a role in excavating and contacting with the outside, and has stronger strength and wear resistance; but long-time friction with the outside also wears faster, so the tool bit 2 needs to be replaced, the tool bit 2 is connected with the tool apron 1, the tool bit 2 can rotate under the action of external force, so the wear is uniform, and the arrangement of the cotter pin 3 can axially limit the tool bit 2 by matching with the annular groove 6 on the tool bit 2, so the tool bit 2 is prevented from being separated; when the tool bit 2 is worn and needs to be replaced, the cotter pin 3 can be knocked out of the pin hole 9, then the tool bit 2 is taken out, the tool bit 2 is replaced, and finally the cotter pin 3 is inserted; has the advantages of preventing the flail knife and being easy to replace.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the design concept of the present invention should be included in the scope of the present invention.
