Problems solved by technology
[0003] The object of the present invention is to provide a loader for engineering vehicles with a quick change device, to solve the problem that the quick change device in the prior art proposed in the above background technology, once separated from the bucket, the bucket will lose its support, and the bucket will easily appear. Accidents caused by falling and hurting people, and because the angle of use of the replacement tool may be different from that of the bucket, the maximum angle that the loader can drive may not meet the needs of the replacement tool, so there are certain troubles and problems during use. The dead angle of the job, so it can't meet the needs of people's use

The invention discloses an engineering van loading machine with a quick-changing device. The engineering van loading machine comprises a diagonal rod, a main frame is arranged below the diagonal rod,the diagonal rod is in rotary connection with the main frame through a pin shaft, a bucket is fixedly connected to the left side of a bent plate, and a connecting frame is arranged on the upper portion of the right side of the bent plate. According to the engineering van with the quick-change device, by means of the cooperation of a sliding block and the bent plate, the bucket is still supported by the sliding block after a first bolt and a second bolt are dismounted, the bucket can not fall suddenly, and the safety in replacement is high; through cooperation of a first supporting rod, a threaded rod and a second supporting rod, the initial angle of the bent plate can be changed under the premise that the loading machine is not driven, the problem that for an existing quick-changing device, as the using angle of a changing tool is different with that of the bucket, certain trouble and operation dead angles exist in the use process is solved, and thus the engineering van loading machinewith the quick-changing device can fully met the using needs of people.
Description
technical field [0001] The invention relates to the technical field, in particular to an engineering vehicle loader with a quick change device. Background technique [0002] The engineering vehicle loader is a large-scale loading equipment. The appearance of the loader has changed the manual loading operation method and provided great convenience for people. In order to meet different operation needs, at the front end of the engineering vehicle loader, A quick-change device is provided so that the bucket can be replaced with different tools. However, once the quick-change device in the prior art is separated from the bucket, the bucket will lose its support, and it is prone to accidents where the bucket falls and injures personnel. , and because the angle of use of the replaced tool may be different from that of the bucket, the maximum angle that the loader can drive may not meet the needs of the replaced tool, so there are certain troubles and dead angles in the process of ...
