Abstract
The utility model relates to an engineering mechanical apparatus, and concretely relates to an improvement made on the mechanical arm of an excavator so as to increase the strength of the excavator, namely, a soil loosening apparatus for increasing the strength of the excavator. A main arm oil cylinder is connected with a main arm, one end of the main arm is connected with a small arm fulcrum, a small arm is connected with a small arm oil cylinder and a soil loosening device oil cylinder, and the soil loosening device oil cylinder is connected with a soil loosening device. The soil loosening apparatus is characterized in that the ratio of a distance from the supporting point of a small arm oil cylinder head to the small arm fulcrum and a distance from the small arm fulcrum to the soil loosening device is 0.4 to 0.8. The soil loosening apparatus provided by the utility model has the advantages that weight of the main arm and the small arm is raised through shortening the arm length and increasing arm thickness; the volume of the hydraulic cylinders is raised, thereby generating larger strength; and the ratio between segments above and below the small arm fulcrum is changed, such that the small arm fulcrum is moved downwards, and the proportion of the length between the small arm fulcrum and the pushing point of the small arm oil cylinder to the length of the whole small arm is increased, thereby raising excavating strength.
Description
Technical field
The utility model relates to a kind of engineering machinery device, is exactly particularly in order to increase excavator strength, and the improvement that excavator mechanical arm aspect is carried out, promptly a kind of device that loosens the soil that excavator strength is increased.
Background technology
Requisite plant equipment when excavator is construction such as current various building, road and bridge, and, produced huge social and economic benefit because the appearance of these mechanized equipments has improved speed of application greatly.But because the difference of construction plant, the emptying in the process of reality, find the excavator of prior art, can't finish excacation for harder soil block because arm strength is little, arm is heavy not enough as the operating personnel of excavator.
Summary of the invention
The purpose of this utility model provides a kind of device that can increase the excavator arm strength, a kind of device that loosens the soil that excavator strength is increased is provided, the technical scheme of taking is: the principal arm oil cylinder is connected with principal arm, principal arm one end is connected with the forearm fulcrum; forearm is connected with the ridge buster oil cylinder with the forearm oil cylinder respectively; the ridge buster oil cylinder is connected with ridge buster, it is characterized in that: it is 0.4-0.8 that the forearm oil cylinder lacks the ratio of a strong point to the distance of forearm fulcrum and forearm fulcrum to the distance of ridge buster.
The wall thickness of described principal arm and forearm is the 2.0-2.5 centimetre, and own wt is increased to the 7-20 ton, has increased the 3-10 ton than before.
The length of described principal arm and forearm is respectively in 6 meters and 3.5 meters.Shortened more than 20% than before.
The capacity of the capacity forearm oil cylinder of described hydraulic cylinder is increased to 32 liters, and the capacity of principal arm oil cylinder is increased to 69 liters, and all capacity has increased by 15% than before.
Advantage of the present utility model is: by shortening brachium, increase the abundant increase that has showed principal arm and forearm own wt of arm; Increase the capacity of hydraulic cylinder, thereby produce bigger strength.Change the ratio of forearm fulcrum two sections, the forearm fulcrum is moved down, the forearm fulcrum is increased to the ratio that the length between the thrust point of forearm oil cylinder accounts for whole little arm lengths, thereby increase the strength of excavating.
Description of drawings
Fig. 1 is the structural representation of device of loosening the soil.
Among the figure,
1-principal arm, 2-principal arm oil cylinder, 3-forearm fulcrum, 4-forearm oil cylinder, 5-forearm, 6-ridge buster.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of device that loosens the soil that excavator strength is increased, the technical scheme of taking is: principal arm oil cylinder 2 is connected with principal arm 1, principal arm one end is connected with forearm fulcrum 3; forearm 5 respectively with forearm oil cylinder 4 be connected with the ridge buster oil cylinder; the ridge buster oil cylinder is connected with ridge buster 6, it is characterized in that: it is 0.4-0.8 that the forearm oil cylinder lacks the ratio of a strong point to the distance of forearm fulcrum and forearm fulcrum to the distance of ridge buster 6.
The wall thickness of described principal arm and forearm is the 2.0-2.5 centimetre, and own wt is increased to the 7-20 ton, has increased the 3-10 ton than before.
The length of described principal arm and forearm is respectively in 6 meters and 3.5 meters.Shortened more than 20% than before.
The capacity of described hydraulic cylinder, the capacity of forearm oil cylinder are increased to 32 liters, and the capacity of principal arm oil cylinder is increased to 69 liters, has all increased by 15% than before.
