Abstract
The utility model discloses a small-sized excavator used in food processing industry, which is characterized by being capable of avoiding the generation of pollution. The small-sized excavator comprises an excavator body and a wheelbarrow arranged at the bottom of the excavator body. By arranging the wheelbarrow at the bottom of the excavator, when the excavator needs to walk, the wheelbarrow is pushed to lead the excavator to be walk; and by arranging an AC motor to drive a hydraulic pump, the AC motor is led to be capable of working so as to lead the hydraulic pump to work and supply oil tohydraulic cylinders on a movable arm, a dipper handle and a shovel loader, thus realizing the work capability of the excavator. Therefore, power units of internal combustion engines arranged on the existing excavators can be eliminated, and the pollution of workplaces can be avoided, thus being particularly suitable for promotion and use in food processing industry.
Description
Technical field
The utility model relates to a kind of excavator, especially relates to a kind of mini-excavator that is used for food-processing industry.
Background technology
At present, existing excavator includes swing arm 5, dipper 7, scraper bowl 8 and excavator platform 1, excavator platform 1 is provided with hydraulic oil pump 4, is respectively arranged with hydraulic cylinder 9 on swing arm 5 and dipper 7, and hydraulic cylinder 9 is provided with oil passage control valve 10 with the oil circuit of hydraulic oil pump 4.During work, hydraulic oil pump 4 drives its work by internal combustion engine as dynamical element, control by oil passage control valve 10, realize the Telescopic of excavator swing arm 5, dipper 7 various pieces respectively, thereby realize the work of scraper bowl 8, and moving of excavator also is to rely on the task driven of internal combustion engine and the ground-engaging element motion of excavator.But when adopting internal combustion engine as dynamical element, its pollution is bigger, and therefore, when needing shovel fortune material in such as food production industries such as product wine industries, excavator all can not use, and can only pass through great amount of manpower, transports with spades, takes time and effort.
The utility model content
Technical problem to be solved in the utility model provides a kind of mini-excavator that prevents to produce pollution.
The technical scheme that its technical problem that solves the utility model adopts is: mini-excavator, comprise the excavator body, and be provided with Trolley in excavator body bottom.
As the preferred version of technique scheme, described Trolley adopts liftable hydraulic manual go-cart.
Further be that the excavator body comprises the excavator platform and be arranged on hydraulic pump on the excavator platform that hydraulic pump is electrically connected motor.
Further be that described motor adopts the 380V ac motor.
The beneficial effects of the utility model are: by the Trolley that is provided with in excavator body bottom, then when excavator need be walked, can make the excavator walking by promoting Trolley; And connect hydraulic pump by the electric electromechanics that is provided with, and then can make motor work and drive hydraulic pump works, and the hydraulic cylinder on swing arm, dipper and the scraper bowl is carried out fuel feeding, make excavator work.Therefore, can cancel the combustion engine powered element that is provided with on the existing excavator, avoid causing the pollution of workplace, be particluarly suitable for promoting the use of in the food-processing industry.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: excavator platform 1, Trolley 2, motor 3, hydraulic pump 4, swing arm 5, dipper 7, scraper bowl 8, hydraulic cylinder 9, oil passage control valve 10.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, mini-excavator of the present utility model comprises the excavator body, is provided with Trolley 2 in excavator body bottom.Then when this excavator need be walked, can make this mini-excavator walking by promoting Trolley 2, thereby can cancel the combustion engine powered element that is provided with on the existing excavator, avoid the workplace is polluted.Trolley 2 can adopt highly fixing cart structure, when then needing with mini-excavator promotion walking, the bottom that must be the excavator body does not contact with ground, and like this, highly Gu Ding Trolley 2 can promote it, but, when this mini-excavator in when work, body itself has certain vibration, and the bottom of excavator body does not contact with ground, sliding of Trolley 2 will be caused, and promptly the walking that this mini-excavator is unnecessary can be caused.As optimal way, described Trolley 2 adopts liftable hydraulic manual go-cart.After adopting liftable hydraulic manual go-cart, when then this mini-excavator is worked, can fall the support face of 2 pairs of excavator bodies of Trolley, the bottom of excavator body is contacted with ground, like this, the vibration of excavator work just can not cause it to slide; And when needs promote this mini-excavator walking, can rise the support face of 2 pairs of excavator bodies of Trolley, and the bottom of excavator body and ground are broken away from, promote its walking and get final product.In addition, this Trolley 2 can be that the bottom and this mini-excavator that directly are fixedly connected on the excavator body form integrative-structure, also can be provided with in this mini-excavator body bottom one with the suitable space of Trolley 2, when needs when production department promotes the walking of this mini-excavator, again Trolley 2 is shifted onto this suitable space, mini-excavator body bottom and is got final product.
In the above-described embodiment, do not adopting internal combustion engine to be used as power under the situation of element, for realizing the Telescopic of this mini-excavator swing arm 5, dipper 7 various pieces, the excavator body comprises excavator platform 1 and is arranged on hydraulic pump 4 on the excavator platform 1 that hydraulic pump 4 is electrically connected motor 3.Then, can drive hydraulic pump 4 work, realize the fuel feeding or the oil return of each hydraulic cylinder 9, can prevent the pollution of the work of this mini-excavator well the production place by motor 3 startup work.Wherein, motor 3 can adopt the 220V ac motor to realize, also can adopt the 380V ac motor, and preferred 380V ac motor, its reliable operation can realize more powerful transmission, and owing to generally all be the power supply that adopts 380V in the factory, therefore, can avoid in factory using the power supply of other different stage to realize the work of this mini-excavator.
