Description
Technical Field
The invention relates to the field of low-carbon environment-friendly equipment, and mainly develops automatic feeding equipment capable of replacing a fuel loader for a mixing station, in particular to an automatic feeding robot.
Background
The invention applies for the new application after improvement and upgrading based on an automatic feeding system applied for 8 months and 8 days in 2022. The CN115045159a document discloses an automatic feeding system for grading materials, which has the biggest defect that the structure design and the configuration of a motor of a cyclic bucket are problematic. The width of the hopper is smaller than the wheel distance of the wheels of the travelling trolley, so that the wheels can continuously climb up the material pile; the common motor is burnt when meeting the obstacle. Therefore, the feeding requirement of the construction site cannot be met. Through continuous improvement of field technicians, the automatic feeding robot for the grading materials, which can meet construction requirements, is creatively designed again.
In the actual feeding and conveying process of the mixing station, the currently used method is to complete feeding by using a loader to feed the mixing hopper from each aggregate bin, and in the process, the feeding is completely performed by evaluating the feeling of the operator of the loader, and the condition of material leakage in each mixing hopper needs to be observed at any time to determine whether the material should be filled. Under the condition that the light is not good at night and the material leakage of the collecting hopper cannot be accurately judged, the phenomenon that a certain grade of aggregate is lacked can occur, and when an operator is tired, the problem that the first aggregate is poured into the second collecting hopper and the second aggregate is poured into the third collecting hopper is wrong can also occur frequently, so that the gradation of the mixture is changed, and the mixing quality of the mixture is affected.
And the cost budget is further that a common 3-4-stage batching mixing field needs to be provided with 1-2 loaders and 2-4 operators, and a 4-7-stage batching mixing field needs to be provided with 3-4 loaders and 6-8 operators. If a assault is encountered, a24 hour overtime operation is required, and more loader operators are required to perform shift operations.
At present, many construction units at home and abroad are explored, and an automatic and unmanned feeding mode is adopted. What has appeared is: CN2018208901137 a concrete mixing station sinking type batching apparatus; also comprises a CN2017204675768 sinking type stabilized soil mixing station, a manufacturing method of the sinking type stabilized soil mixing station, a container type sinking batching device and other new processes. The method is automatic, a large amount of concrete is required to be constructed underground in a collecting bin, a space for sinking conveying equipment is reserved for installing the sinking conveying equipment, high site building cost is required to be input in the early stage, the service period is less than 1-2 years, and the service period is not more than 5 years.
At present, an asphalt concrete mixing station and a cement stabilized soil mixing station for engineering construction in China are built temporary mixture mixing stations. Asphalt stations are fastest for 1-2 years, water stable for 2-3 years, and cement concrete stations for hydropower and tunnel engineering have been in existence for more than 5 years. After the mixing station finishes the mixing task of the mixture, 99% of the mixing stations are required to be completely removed, a large amount of concrete below the bin is crushed after the bin is removed, and the mixing stations are subjected to site re-tillage, so that a large amount of construction wastes are required to be cleared, and more construction cost is caused for a construction unit.
Therefore, the sinking type mixture mixing station is a very wasteful resource, and the least preferable method for realizing automation has no great popularization value and is not suitable for comprehensive popularization and application. How to develop a feeding system with small occupied area, low input cost and quick field installation, without carrying out a large amount of foundation construction and field repeated tillage disposal cost in the later period, various grading materials such as coarse aggregates, fine aggregates, fillers and the like stacked on the ground can be directly conveyed to a collecting hopper according to a proportion, and the feeding system is an optimal automation scheme which is urgently needed by a plurality of construction units.
