Abstract
A digging and soil-shifting double-purpose bucket comprises a bucket body, wherein the included angle between the upper end of the bucket body and the inner wall on the lower end of the bucket body is 65 to 95 degrees, the shape of the bucket body is wider in the middle portion and narrows gradually to two ends, edges of the upper end of the bucket body and/or the lower end of the bucket body are provided with outward convex bucket teeth, a connecting sleeve I is arranged outside the middle portion of the bucket body, and a connecting sleeve II is arranged outside the top portions of the bucket teeth on the lower end of the bucket body. The bucket of the invention can be used for digging and shifting soil and realizes digging and shifting soil with one machine, and the digging amount in one time is increased simultaneously, thereby lowering the energy consumption and improving the working efficiency.
Description
Technical field
The present invention relates to a kind of scraper bowl, relate in particular to a kind of excavation, soil-shifting double-purpose bucket.
Background technology
Existing excavator, for example, Chinese patent CN101158165A disclosed " double-power hydraulic digging machine " generally is to be made of hydraulic system, track bottom car assembly, slewing equipment, driver's cabin and operating mechanism etc.Operating mechanism comprises swing arm, dipper and scraper bowl.At present, people require more and more higher to functional requirement, operation requirement, environmental requirement and the energy consumption of excavator.And existing excavator can only excavate, function singleness, and single excavation amount is little, energy consumption height, inefficiency.Its reason mainly is the poor structure of its scraper bowl.
Summary of the invention
The objective of the invention is to solve existing power shovel function singleness, the shortcoming that capacity is little provides a kind of function many, and the excavation amount is bigger, the digging and soil-shifting double-purpose bucket of high efficiency.
The objective of the invention is to be achieved through the following technical solutions, it comprises the scraper bowl body, and the angle of described scraper bowl body upper end and scraper bowl body lower end inwall is 70-95 ° (preferred 70-90 a °), and the scraper bowl body shape is the middle part broad, progressively narrows to two ends; There is the teeth of outside protrusion at the edge of scraper bowl body upper end and/or scraper bowl body lower end; The outside, scraper bowl body middle part is provided with adapter sleeve I, and the teeth tip position of scraper bowl body lower end is provided with adapter sleeve II.
The teeth quantity that the edge of scraper bowl body upper end and scraper bowl body lower end outwards protrudes, evenly distributes by preferred five to seven respectively.
The scraper bowl body is connected with the assembling of excavator boom: the scraper bowl body is hinged by the adapter sleeve II and the excavator boom of the adapter sleeve I outside its middle part and its lower end teeth tip position.
The present invention's scraper bowl is installed on the existing excavator, and excavator just both can carry out digging operation, the operation of can bulldozing again, and simultaneously, the excavation amount of single increases, and energy consumption reduces, and increases work efficiency.
Description of drawings
Fig. 1 is a scraper bowl embodiment side sectional view of the present invention;
Fig. 2 is a scraper bowl embodiment front view of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Embodiment 1
With reference to accompanying drawing 1, present embodiment comprises the scraper bowl body, and the angle of scraper bowl body upper end 2 and scraper bowl body lower end 4 inwalls is 90 °, and the scraper bowl body shape is the middle part broad, progressively narrows to two ends; There is the teeth 1 of outside protrusion at the edge of scraper bowl body upper end 2, and there is the teeth 7 of outside protrusion at the edge of scraper bowl body lower end 4; The outside, scraper bowl body middle part is provided with adapter sleeve I, and the teeth II 7 top outer positions of scraper bowl body lower end 4 are provided with adapter sleeve II 5.
Scraper bowl body upper end 2 and scraper bowl body lower end 4 teeth quantity respectively are five, evenly distribute.
Fig. 2 is the front view of present embodiment, the circular arc side 8 of visible scraper bowl.This circular arc scraper bowl has expanded the actual capacity of scraper bowl, and the excavation quantitative change of single operation is big, has improved production efficiency.
The scraper bowl body is connected with the assembling of excavator boom: the scraper bowl body is hinged with excavator boom by the adapter sleeve II 5 of adapter sleeve I 3 outside its middle part and 4 teeth II, 7 top outer positions, its lower end.
The angle of scraper bowl body upper end 2 and scraper bowl body lower end 4 inwalls is 80 °.Surplus with embodiment 1.
Embodiment 3
The angle of scraper bowl body upper end 2 and scraper bowl body lower end 4 inwalls is 70 °.Surplus with embodiment 1.
The equipment of excavator is a device of directly finishing mining task.Three parts are hinged forms by swing arm, dipper, scraper bowl etc. for it.Swing arm rises and falls, dipper stretches and the control of reciprocating double-action hydraulic cylinder is all used in the scraper bowl rotation.Because the change of the articulated position of scraper bowl and dipper, when dipper stretched, scraper bowl body upper end 2 was last, and scraper bowl body lower end 4 ground proximitys just can be finished the operation of bulldozing; When the dipper retraction, and constantly change the position, just can realize dredge operation.
The theoretical foundation that circular arc scraper bowl of the present invention expands actual capacity is as follows.
Excavating resistance is meant the soil resistance that scraper bowl is run in mining process, it acts on the bucket point in approximate usually thinking, and can decompose tangential resistance Pt and normal direction resistance Pn according to the tangential direction of mining track.Present rough algorithm is:
Pt＝σbc Pn＝ψPt
In the formula: σ is determined by test for excavating specific resistance; B is wide for bucket; C is a thickness of cutting; ψ is a coefficient, is determined by test.
When the coefficient of admission of the coefficient of volumetric expansion of disregarding soil and scraper bowl,, should have in order in certain excavation stroke, to fill scraper bowl
q＝bcL
In the formula: c is a thickness of cutting; Q is a dipper capacity; C is a thickness of cutting.
Pt＝σ×b×c＝σq/L
Promptly excavate merit: Pt L=σ q
In mining process, Pn does not do work, and has only the Pt acting, abbreviates the excavation merit as.When the soil grade of excavating object and dipper capacity can be determined, just can determine excavation merit PtL by following formula.
Scraper bowl of the present invention both sides are designed to circular arc, and b struggles against wide constant, and the c thickness of cutting is constant, and the c thickness of cutting is certain, and then the q dipper capacity is constant, thereby it is constant to excavate merit Pt L=σ q.The scraper bowl both sides are circular arc, and it is big that the surface area of scraper bowl becomes, and its actual dipper capacity becomes big, thereby single excavation quantitative change is big, and energy consumption reduces, and has improved operating efficiency.
