At present, the bucket tooth round pin is when the assembly, and its middle part is interference fit with the cooperation of second through-hole, need beat the bucket tooth round pin during the assembly and go into the side can assemble firmly, but this kind of mounting means is very inconvenient when later stage maintenance, in case the bucket tooth damages when needing to be changed, needs beat the bucket tooth round pin out to along with the extension of live time, the bucket tooth round pin is direct to be blocked in the through-hole sometimes even, and this has brought very big inconvenience for subsequent maintenance work.

SUMMERY OF THE UTILITY MODEL

The utility model provides a simple to operate's bucket tooth round pin, its main aim at overcome the inconvenient problem of current bucket tooth round pin dismouting.

In order to solve the technical problem, the utility model adopts the following technical scheme:

Furthermore, the right-hand member of first right round pin section is equipped with the screw thread section, the left end of second left round pin section is equipped with the screw hole with screw thread section complex, the left end face of first left round pin section is equipped with left hexagon socket, the right-hand member face of second right round pin section is equipped with right hexagon socket.

From the above description of the present invention, compared with the prior art, the present invention has the following advantages: the utility model discloses novel structure, design benefit, bucket tooth round pin when the assembly, pass first right round pin section in proper order through the first through-hole and the second through-hole of bucket tooth left side wall, the second left round pin section passes first through-hole and the second through-hole of bucket tooth right side wall in proper order, then connect the right-hand member of first right round pin section and the left end of second left round pin section, left step face is inconsistent with the left end face of second through-hole, right step face is inconsistent with the right-hand member face of second through-hole after the connection is accomplished; when the bucket tooth needs to be changed, can dismantle with first right round pin section and the left round pin section disconnect-type connection of second. The utility model discloses the dismouting is simple and convenient more, the subsequent maintenance work of the bucket tooth of being convenient for.

FIG. 2 is a view showing the configuration of the tooth and the tooth holder.

Detailed Description

Refer to fig. 1 and 2. The utility model provides a convenient dismounting's bucket tooth round pin, includes left side round pin body 1, right side round pin body 2, left side round pin body 1 includes first left side round pin section 11 and first right side round pin section 12, the diameter of first left side round pin section 11 is greater than the diameter of first right side round pin section 12, and the junction of first left side round pin section 11 and first right side round pin section 12 forms left step face 13, first left side round pin section 11 and the first through-hole 31 looks adaptation of 3 left side walls of bucket tooth. The right side round pin body 2 includes second left side round pin section 21 and second right side round pin section 22, the diameter of second right side round pin section 22 is greater than the diameter of second left side round pin section 21, and the junction of second left side round pin section 21 and second right side round pin section 22 forms right step face 23, second right side round pin section 22 and the first through-hole 31 looks adaptation of tooth 3 right side wall. The first right pin section 12 and the second left pin section 21 are matched with a second through hole 41 of the tooth holder 4, the right end of the first right pin section 12 is detachably connected with the left end of the second left pin section 21, the first right pin section 12 and the second left pin section 21 are matched with the second through hole 41 of the tooth holder 4, and the sum of the lengths of the first right pin section 12 and the second left pin section 21 after connection is equivalent to the length of the second through hole 41.

Refer to fig. 1. The right end of the first right pin section 12 is provided with a threaded section 14, the left end of the second left pin section 21 is provided with a threaded hole 24 matched with the threaded section, the left end face of the first left pin section 11 is provided with a left hexagon socket 15, and the right end face of the second right pin section 22 is provided with a right hexagon socket 25.

Refer to fig. 1 and 2. When the bucket tooth pin is assembled, a first right pin section 12 sequentially penetrates through a first through hole 31 and a second through hole 41 of the left side wall of a bucket tooth 3, a second left pin section 21 sequentially penetrates through the first through hole 31 and the second through hole 41 of the right side wall of the bucket tooth 3, then two hexagonal adjustable wrenches are adopted, one hexagonal adjustable wrench is matched with a right inner hexagonal hole 25 to enable the second left pin section 21 to be fixed, the other hexagonal adjustable wrench is matched with a left inner hexagonal hole 15, the first right pin section 12 is rotated to enable a threaded section 15 to be matched with the threaded hole 25 until the first right pin section 12 is screwed, so that the right end of the first right pin section 12 is connected with the left end of the second left pin section 21, after connection is completed, a left step surface 13 is abutted against the left end surface of the second through hole 41, and a right step surface 14 is abutted against the right end surface of the second through hole 41; when the bucket tooth 3 needs to be replaced, the first right pin section 12 and the second left pin section 21 are connected separately and can be detached.
