Abstract
The utility model discloses a boom excavator, and relates to the engineering technical field. The utility model is mainly characterized in that an electromotor is adopted as the power source; the front of machine body is provided with a boom which can swing leftward, rightward, downward and upward; the front end of the boom is provided with a rotation hobbing cutter; an expansible lingual plate; a transmission belt is provided with the boom; a material receiving hopper is arranged below the rear end of the boom; the bottom of the material receiving hopper is provided with a material outlet transmission belt, the trial of which has a material outlet. Compared with the prior art, the utility model has the advantages of structural simplicity, flexibility and cost-effectiveness, therefore is suitable for use in subway tunnel soil excavation, underground coal extraction, etc.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is a kind of machinery of digging a hole that can dig a hole into the earth, mine.
Background technology
Present domestic subway tunnel excavation still is the hand excavation mostly, and inefficiency and safety factor are low.The import earth boring machine is owing to factors such as complex structure, cost height, maintenance difficult are seldom used.Existing coal-winning machine makes its application be subjected to certain limitation because mobility is poor.A kind of maneuverability, the economical and practical machinery of digging a hole if can be designed, these difficult problems can be solved.
Summary of the invention
The purpose of this utility model is design a kind of simple structure, maneuverability, economical and practical movable arm type earth boring machine.
Technical solution adopted in the utility model is the swing arm principle that adopts existing excavator, reaches revolving of coal-winning machine and cuts conveying principle, they is organically combined, and become a kind of novel earth boring machine.In order to keep with fresh air in the hole, power source adopts motor to be used as power.The swing arm that can bob and weave is set in the front of fuselage, the front end of swing arm is provided with rotary cutting roller knife, and the rotary cutting roller knife below is provided with stretching lingual plate, is provided with the swing arm conveyer belt in the swing arm, below, swing arm rear end is provided with receiving hopper, and the receiving hopper bottom is provided with the discharging conveyer belt.
Because the utility model adopted technique scheme, compare with the existing machinery of digging a hole, have simple in structure, maneuverability, advantage such as economical and practical, be fit to multiple uses such as subway tunnel shoveling, down-hole coal excavation.
Description of drawings
Fig. 1 is a side-looking structural representation of the present utility model.
Fig. 2 is a plan structure schematic diagram of the present utility model.
Among the figure: 1 rotary cutting roller knife, 2 hydraulic motors, 3 arc skateboards, 4 swing arm conveyer belts, 5 swing arms, 6 swing ox heads, 7 transmit motor, 8 receiving hoppers, 9 driver's cabins, 10 hoods, 11 discharging conveyer belts, 12 oscillating oil cylinders, 13 hoist cylinders, 14 hyoplastron oil cylinders, 15 stretching lingual plates, 16 crawler belts, 17 lower walls.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Fig. 1, shown in Figure 2, fuselage of the present utility model front connects swing ox head 6, swing ox head 6 tops connect swing arm 5, swing arm 5 front ends are provided with rotary cutting roller knife 1, rotary cutting roller knife 1 built-in hydraulic motor 2, rotary cutting roller knife 1 below is provided with arc skateboard 3, stretching lingual plate 15 and hyoplastron oil cylinder 14, swing arm 5 built-in swing arm conveyer belts 4, swing arm 5 rear ends are equipped with transmits motor 7, and hoist cylinder 13 is installed in swing arm 5 back lower places, and ox head 6 rears are provided with receiving hopper 8, oscillating oil cylinder 12, receiving hopper 8 back upper places are provided with driver's cabin 9, hood 10 is arranged behind the driver's cabin 9, and the receiving hopper bottom is provided with discharging conveyer belt 11, and underbelly has crawler belt 16, lower wall 17.
It bobs and weaves swing arm 5 by 12 controls of hoist cylinder 13, oscillating oil cylinder, and rotary cutting roller knife 1 moves cutting with it.Cutting diffusing soil (or coal) down arrives swing arm conveyer belt 4 through stretching lingual plate 15, arc skateboard 3, sends into receiving hopper 8 through swing arm conveyer belt 4 again, send car by discharging conveyer belt 11 again after.Arbitrarily control movable arm swinging, can dig round hole, square hole and irregular hole.
