Problems solved by technology

[0004] When carrying out rail transit construction in cold places in the north, the bucket of the excavator is required to excavate the frozen soil. Since the surface of the frozen soil is relatively hard, if the teeth of the bucket are directly used to tap the frozen soil for excavation, the After a long time of knocking, it is easy to cause damage to the bucket teeth of the bucket, and the traditional bucket does not have a device for breaking frozen soil, which makes it difficult for the bucket to excavate frozen soil directly

Embodiment 1

[0034] see Figure 1-Figure 3 As shown, a foundation pit excavation device for rail transit construction according to the embodiment of the present invention includes a bucket 1 and bucket teeth 2, and one end of the bucket 1 is fixedly installed with the bucket teeth 2; A base 31 is movably installed on both sides, a vibration motor 32 is fixedly installed on one side of the base 31, a connecting plate 33 is fixedly installed on one side of the base 31 close to the vibration motor 32, and the two connecting plates 33 are close to each other. A connecting block 34 is fixedly installed on one side, and an inserting block 35 is fixedly installed on one side of the connecting block 34; when rail transit construction is carried out in a cold place in the north, the bucket 1 of the excavator is required to excavate the frozen soil. The surface of the soil is relatively hard. If you directly use the bucket teeth 2 of the bucket 1 to tap the frozen soil for excavation, the bucket tee...

Embodiment 2

[0044] like Figure 9 As shown, comparative example one, wherein another embodiment of the present invention is:

[0045] A magnet block 9 is fixedly installed on the top of the cleaning plate 704, and the rotating block 708 is made of iron; during operation, after cleaning the bucket 1, the rotating block 708 is reset with the crushing ball 710 and the conical block 711, Since the rotating block 708 is made of iron, the rotating block 708 and the magnet block 9 on the cleaning plate 704 will be adsorbed and fixed to each other, and the unused rotating block 708 and the crushing ball 710 will be fixed to prevent the rotating block 708 from carrying the crushing ball 710 Rotation can damage parts.

[0046]Working principle: when the bucket 1 is excavating the frozen soil, the vibration motor 32 on the base 31 is activated. The vibration motor 32 is the prior art. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric block obtains the exciti...

Abstract

The invention belongs to the field of excavating equipment, and particularly relates to a foundation pit excavating device for rail transit construction, which comprises a bucket and bucket teeth, and the bucket teeth are fixedly mounted at one end of the bucket; a base is fixedly installed on the two sides of the bucket, a vibration motor is fixedly installed on one side of the base, and a connecting plate is fixedly installed on the side, close to the vibration motor, of the base. When the bucket excavates frozen soil, the vibration motor on the base is started, the vibration motor drives the base and the connecting plates to vibrate together, at the moment, the inserting block between the two connecting plates also vibrates along with the base, and when the bucket makes contact with the frozen soil, the tip ends of the connecting plates and the tip ends of the inserting block also make contact with the frozen soil; due to the fact that the connecting plate and the inserting block vibrate all the time, the bucket teeth can vibrate and crush frozen soil when entering the frozen soil, the bucket teeth of the bucket can quickly and effectively enter the frozen soil to excavate, and the effect of conveniently crushing and excavating the frozen soil is achieved.

Description

technical field [0001] The invention belongs to the technical field of excavation equipment, in particular to a foundation pit excavation device for rail transit construction. Background technique [0002] Excavation equipment usually refers to excavators, and when excavators are excavating, they all need to be excavated through buckets, and the buckets are used to load soil. [0003] A Chinese patent with publication number CN112502209A discloses a foundation pit excavation device for building construction. The main points of its technical solution are: it can effectively speed up the excavation rate of the foundation pit soil and the transportation efficiency of the excavated soil, and saves manual excavation. time, reduce labor costs, and improve the efficiency of foundation pit excavation. [0004] When carrying out rail transit construction in the cold regions of the north, the bucket of the excavator is required to excavate the frozen soil. Since the surface of the fr...
