Description

Construction equipment with interlocking instrument of dozer and roller}

The present invention relates to construction equipment equipped with a dozer and roller interlocking mechanism. In particular, a dozer and a roller are arranged at the front and rear of construction equipment including an excavator, and the dozer and roller are interlocked on a rotating frame to level the ground. In addition to the selective use of rollers for the function of the dozer and ground compaction, the first and second replacement blades are detachably attached to the front lower part and both sides of the dozer blade to improve and maintain the durability of the parts of the dozer device. This relates to construction equipment equipped with a dozer and roller linkage mechanism whose structure has been improved to reduce maintenance costs.

In general, an excavator refers to a construction machine for transporting, loading, and excavating soil and materials. In addition, attachments are installed on excavators, and work varies depending on the type of attachment installed.

Such excavators work by exchanging two to three attachments per task.

Attachments used in excavators include buckets, tongs, and breakers.

However, since an excavator can usually install only one attachment at a time, in order to use another attachment, the excavator must move to the location where the attachment required for the work is located.

Additionally, there is often a long distance between the location where the necessary attachments are located and the location where the excavator works. Therefore, there is a problem that it takes a lot of time to replace it with the necessary attachment.

In addition, since it takes a lot of time to replace the attachment, there is a problem that the work efficiency of the excavator is reduced.

As a prior art related to an excavator equipped with an existing dozer, as disclosed in Korean Patent Publication No. 10-2195598 "Excavator equipped with a dozer device" (registration date: December 21, 2020), the dozer device is installed at the lower part of the excavator. It includes a dozer frame coupled to a dozer frame, a dozer blade provided on one side of the dozer frame, and a support portion coupled to an upper end of the dozer blade and formed in a hook shape with one end bent.

Conventional prior art related to existing road paving rollers includes a vehicle body and a rotatable device on the vehicle body, as disclosed in Korean Patent Publication No. 10-1239402 "Roller Device for Road Paving" (registration date: 2013.02.26) In the road paving roller device that is installed and includes a roller wheel that supports the running of the vehicle body and flattens the support surface, when the vehicle body runs backwards, if a worker or obstacle is located behind the vehicle body, it is It is provided with a safety unit that detects and automatically stops the running of the vehicle body, and the safety unit includes a rotation shaft rotatably installed at the rear of the vehicle body, a rotation rod extending from the rotation shaft, and a rear of the roller wheel. A sensing unit installed on a rotating rod and including a contact panel that rotates the rotating rod and the rotating shaft by contacting an operator or an obstacle located at the rear of the vehicle body, and the contact panel being activated by an operator or an obstacle located at the rear of the vehicle body It includes a vehicle stop unit that stops the vehicle body by driving a parking brake provided on the vehicle body when this pressure is applied and the rotation shaft rotates.

However, as previously explained, existing construction equipment has the disadvantage of increasing construction costs because the dozer and roller cannot be mounted together on one excavator equipment, and must be installed by replacing the attachment or put into the construction site as separate equipment. There is.
