Detailed Description

The invention is further described below with reference to the accompanying drawings:

examples

An adjustable katter tooth holder is shown in figures 1-5 and comprises a tooth holder 1, a tooth sleeve 2 and a pin 3; the tooth holder 1 is fixedly arranged at the front end of an excavator bucket; the gear sleeve 2 is connected to the front end of the gear seat 1 and is fixedly connected with the gear seat 1 through a pin 3; the toothholder 1 comprises a fixed seat 11, a connecting tooth 12, a fixed screw 13, a fixed nut 14 and a locking bolt 15; the fixing seat 11 is in a concave shape, the rear end of the fixing seat is provided with a clamping groove 112, and the fixing seat 11 is clamped at the front end edge of the excavator bucket through the clamping groove 112; mounting through holes are formed in the upper side and the lower side of the clamping groove 112 at the rear end of the fixing seat 11, a fixing screw 13 and a fixing nut 14 are mounted in the mounting through holes, and the fixing seat 11 is fixedly connected with the edge of the front end of the excavator bucket through the fixing screw 13 and the fixing nut 14; the front end of the fixed seat 11 is provided with a connecting cavity 111, and the upper side and the lower side of the connecting cavity 111 are provided with connecting holes; the connecting teeth 12 are positioned at the front end of the fixed seat 11, the rear ends of the connecting teeth 12 are arranged in the connecting cavity 111, and threaded holes are formed in the upper side and the lower side of the rear ends of the connecting teeth 12; the connecting teeth 12 are fixedly connected with the fixed seat 11 through locking bolts 15; a cushion cover 4 is fixedly arranged between the tooth holder 1 and the tooth sleeve 2.

The working principle is as follows:

example 1:

as shown in the first drawing: the toothholder 1 is clamped on the front side edge of the excavator bucket through the rear end clamping groove 112, and is fixedly arranged on the excavator bucket through the fixing screw rod 13 and the fixing nut 14, when the toothholder 1 is worn or broken, only the fixing screw rod 13 and the fixing nut 14 need to be dismounted through a wrench, the worn or broken toothholder 1 is dismounted, a new toothholder 1 is replaced from the new toothholder 1, and the new toothholder 1 is fixedly connected to the front end of the excavator bucket through the fixing screw rod 13 and the fixing nut 14; the traditional tooth holder 1 is not required to be welded on the excavator bucket; the rapid connection and separation of the toothholder 1 and the bucket are realized through the clamping groove 112, the fixing screw 13 and the fixing nut 14, so that the replacement of the toothholder 1 is convenient and rapid; meanwhile, the replacement cost is reduced.

Example 2:

as shown in fig. two: the toothholder 1 adopts split type, toothholder 1 divide into fixing base 11 and connection tooth 12, after on the excavator bucket is installed to toothholder 1, still can come with changing connection tooth 12 through dismantling locking bolt 15, when the bucket that need change different length and shape digs the tooth under the different scene of digging, accessible spanner rotates locking bolt 15 and makes locking bolt 15 loosen connection tooth 12, connecting tooth 12 is being taken off and is following connection tooth 12 and the corresponding tooth cover 2 of changing different length and shape, fixing through locking bolt 15, thereby satisfy required digging tooth under the different condition of digging.

Example 3:

as shown in fig. four and fig. five: under the scenes of lower excavation strength, the position of the connecting tooth 12 in the connecting cavity 111 can be adjusted by loosening the locking bolt 15, and the connecting tooth 12 is connected with the fixed seat 11 through the locking bolt, so that the extending length of the connecting tooth 12 is longer, and the effect of adjusting the extending length of the connecting tooth 12 is achieved; the cushion cover 4 is arranged between the connecting tooth 12 and the tooth sleeve 2 for use, so that bucket teeth on the bucket become longer and can extend into soil layers more easily, and the excavation working efficiency is improved.
