Abstract
The utility model relates to a multipurpose digger which is refitted by a farm tractor. On the basis of the existing wheel digger, the multipurpose digger is additionally provided with a hydraulic scraping function or hydraulic dozing and leveling function, and the purpose of one machine with two functions and two purposes can be achieved. The application range of a wheel digger is enlarged. The multipurpose digger overcomes the defects of the existing wheel digger that the existing wheel digger only can complete digging earth work, and can not complete more work tasks. The multipurpose digger is suitable for popularizing and using in the works, such as digging earth work, soil leveling, etc., of farmland capital construction and fundamental establishment construction. The multipurpose digger can play the role of advancing the mechanization of earth work construction in the massive countryside. Because the utility model has the characteristics of small size, portability and strong maneuverability, the multipurpose digger can exert specific action in large-scale earth work construction.
Description
Affiliated technical field
The utility model relates to a kind of farm machinery, and especially a kind of farm tractor can satisfy the multipurpose excavator of engine requests such as excavation, shovel soil, level land after repacking.The utlity model has good practical value, promote the use of in the operations such as being adapted in farmland capital construction, the infrastructure construction excavating cubic metre of earth, leveling land.Realize earthwork construction mechanization for satisfying vast rural area, play a role in promoting.Because it has small and exquisite, light, mobility strong, also can bring into play special role in large-scale earthwork construction.
Background technology
In farmland capital construction and infrastructure construction, because the engineering quantity of the earthwork is big, task is heavy, has a strong impact on programming.Along with mechanization degree improves, excavator, loader etc. appears at the scene of construction, for accelerating the earthwork construction progress, alleviates physical labor intensity, has played huge effect.At present, the kind of excavator is divided two kinds, i.e. crawler type and wheeled.Crawler-mounted excavator is big with its power, and the efficient profundity is liked by the constructor.Its shortcoming involves great expense, and walking is inconvenient, only is applicable to large-scale ground works.Though wheel excavator power is little, low, the maneuverability of cost demonstrates huge effect equally in small-sized ground works.
Wheel excavator generally is to adopt wheeled tractor to convert, and just at rear tractor the hydraulic excavating device is arranged.The hydraulic excavating device comprises: adopt bearing pin to connect big arm on the reversing frame, big arm connects forearm, and forearm connects backhoe.Clutch connects gear pump, for hydraulic cylinder provides high voltage power liquid.High voltage power liquid is transported to reversing frame hydraulic cylinder, big arm hydraulic cylinder, little arm hydraulic cylinder, backhoe hydraulic cylinder by hydraulic valve, reversal valve through high-pressure hose.Handle reversal valve, can finish cubic metre of earth task of excavating flexibly, easily.
But when needs shovel native operation, and when being the lorry loading earthwork, existing wheel excavator is difficulty relatively; When needs carry out grading operation, to level land, existing wheel excavator is more difficult.Wheel excavator only has the excavation function, does not possess shovel soil, level land function.
Summary of the invention
The purpose of this utility model is: a kind of tractor modification excavator is provided, on original wheel excavator basis, increases the native function of shovel or increase the level land function, reaching a machine has two kinds of functions, and purpose double-duty is arranged, and enlarges the wheel excavator scope of application.Overcome original wheel excavator and only can finish digging operation, can not finish the deficiency of more job tasks.
The utility model is that the scheme that its technical problem of solution is taked is: the hydraulic pressure scraper device is arranged in wheel excavator the place ahead or hydraulic pressure level land device is arranged.Utilize the tractor onward impulse to cooperate, the earthwork is scooped up or ground is pushed away flat with hydraulic shovel soil, level land device.
The hydraulic pressure scraper device comprises: adopt bearing pin to connect dipper-arm on the fixed mount, dipper-arm adopts bearing pin to connect scraper bowl.Fixed mount and dipper-arm have two respectively, are separately positioned on both sides, wheel excavator chassis.High voltage power liquid is transported to dipper-arm hydraulic cylinder and scraper bowl hydraulic cylinder by hydraulic valve, reversal valve through high-pressure hose.The dipper-arm hydraulic cylinder has two, and the one end is connected on the fixed mount, and an end is connected the dipper-arm middle part.The scraper bowl hydraulic cylinder is two, and scraper bowl hydraulic cylinder one end is connected on the dipper-arm clamping plate, and an end is connected on the scraper bowl.
Hydraulic pressure level land device comprises: connect pivoted arm by bearing pin on vehicle frame, the pivoted arm other end is fixed with the level land plate.Pivoted arm has two, is separately positioned on both sides, wheel excavator chassis.High voltage power liquid is transported to boom hydraulic cylinder by hydraulic valve, reversal valve through high-pressure hose.Boom hydraulic cylinder is two, and an end is connected on the vehicle frame, and an end is connected on the pivoted arm.Boom hydraulic cylinder also can be one, and when boom hydraulic cylinder was one, boom hydraulic cylinder one end was connected the vehicle frame middle part, and an end is connected plate middle part, level land.
The beneficial effects of the utility model are: hydraulic pressure level land device is installed in wheel excavator the place ahead, the modification excavator has possessed excavation, the two kinds of functions in level land, or at wheel excavator the place ahead installation hydraulic pressure scraper device, the modification excavator has possessed excavation and two kinds of functions of shovel soil.One chaptrel formula excavator has two kinds of purposes, has overcome original wheel excavator and only can finish the excavation earthwork, can not finish the deficiency of more job tasks.In addition, hydraulic pressure level land device or scraper device are installed in wheel excavator the place ahead, have obtained another beyond thought effect: increase the wheel excavator forward weight, play the effect of balance when excavator is worked.
