Abstract
The utility model discloses an air scoop for an air pick, which wraps the periphery of an air outlet hole of the air pick. The air outlet hole of the air pick passes through an inner cavity of the air scoop and is communicated with the outside, a transverse baffle plate and a longitudinal baffle plate are arranged in the inner cavity of the air scoop, the transverse baffle plate is perpendicular to the central axis of the air pick, and the longitudinal baffle plate is perpendicular to the transverse baffle plate through the central axis of the air pick. Airflow of the air outlet hole tortuously and smoothly flows, linear movement of exhaust airflow is eliminated, exhaust velocity is decreased, and the problems of low power, high noise and poor freezing resistance of an original air pick in operation.
Description
Technical field
The utility model relates to a kind of gas pick, is particularly for a kind of gas pick and uses air scoop.
Technical background
Gas pick is to be the novel pneumatic instrument of power with compressed air, is widely used in operation occasions such as soft rock fragmentation, pavement breaking, house breaking, urban construction.The gas pick of prior art is only adopted simple slice structure with air scoop, the venthole of gas pick and air scoop distance are near, space length is very little, the airborne globule very easily is adsorbed on its surface, when ambient temperature is low (5～0 ℃), just knurl is iced in exhaust outlet formation outside easily, stops up the exhaust passage and causes equipment to work.In addition, easily produce the effect at the whistle during exhaust, noise is bigger, is difficult to reach present environmental protection requirement.
The utility model content
In order to address the above problem, the purpose of this utility model provides that a kind of efficient height, noise are low, anti-freeze type can good gas pick be used air scoop.
For achieving the above object, the technical solution of the utility model is that a kind of gas pick is used air scoop, be wrapped in around the venthole of gas pick, the venthole of gas pick is through the inner chamber of air scoop, pore by air scoop is in communication with the outside, and it is characterized in that the inner chamber of air scoop contains transverse baffle and longitudinal baffle.The transverse baffle of air scoop inner chamber is vertical with the axis of gas pick, and longitudinal baffle is vertical with transverse baffle through the axis of gas pick, and two deflection plates are all crossing with the venthole of air scoop.
Its operation principle is: the venthole of gas pick is discharged air-flow, and exhaust airstream makes air-flow make a circulation to turn back by the deflection plate in the air scoop, and smooth flowing eliminated the rectilinear motion of exhaust stream, reduces exhaust velocity.
Beneficial effect: the utility model method has compared with prior art solved the problem that power is low, noise big, anti-freeze type can differ from.Adopt the making material of engineering plastics, reduced the manufacturing cost of air scoop, and replacing is more easy, has improved operating efficiency as air scoop.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, present embodiment is being to implement under the prerequisite with technical solutions of the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model.
As Figure 1-3, the transverse baffle 1 of air scoop inner chamber is vertical with the axis of gas pick, longitudinal baffle 2 is vertical with transverse baffle 1 through the axis of gas pick, two deflection plates are all crossing with the venthole 3 of air scoop, as shown in Figure 4, air scoop is wrapped in around the venthole 3 of gas pick, and the venthole 3 of gas pick is through the inner chamber of air scoop, and the venthole 3 by air scoop is in communication with the outside.When exhaust airstream during by the deflection plate in the air scoop, air-flow is circuitous turns back, and smooth flowing eliminated the rectilinear motion of exhaust stream, reduced the speed of exhaust.And as shown in Figure 5, Primordial Qi pick air scoop and outer exhaust outlet space length are too small, and the airborne globule very easily is adsorbed on its surface, gas be compressed or the process that dumps that expands in, need to absorb the heat in the atmosphere, so the low temperature of formation exhaust outlet.When ambient temperature is low (5～0 ℃), just knurl is iced in exhaust outlet formation outside easily, stops up the exhaust passage and causes equipment to work.And venthole 3 distances of air scoop and gas pick body are too small, form the effect at the whistle easily, produce very big noise.After using the designed air scoop of the utility model instead, strengthened the distance of venthole 3 with the air scoop housing of gas pick body, and air-flow during through deflection plate through the rectification of deflection plate, reduced the flow velocity of air-flow, substantially can not produce the effect at the whistle, the noise that has produced when having reduced the work of gas pick.In addition, adopt the making material of engineering plastics polyethylene as air scoop, the manufacturing cost of not only having saved air scoop, and be not easy the globule in the absorbed air when temperature is low makes the formation difficulty more of ice knurl.
