Abstract
The utility model relates to a portable power air pick. The utility model comprises a machine head and a drill sleeve which is arranged on the lower part of the machine head, wherein, the upper part of the machine head is connected with a cylinder body. An air cylinder sleeve is fixed in the cylinder body. A sealing hollow cavity is arranged between the outer wall of the air cylinder sleeve and the inner wall of the cylinder body. The outer wall of the air cylinder sleeve is provided with a through hole which is communicated with the sealing hollow cavity. The head part of an impact piston rod is arranged in the air cylinder sleeve to slide and match. The upper part of the cylinder body is connected with a small power source. An output shaft of the small power source is eccentrically connected with the upper end of a connecting rod through a driving mechanism. The lower end of the connecting rod is connected with a piston block arranged in an air cylinder sleeve to form a piston reciprocating action device. The utility model has the advantages of compact structure, independent work and use without connecting air compressors, convenient and flexible operation and portability, and strong impact frequency and strength.
Description
Technical field: the utility model relates to a kind of pneumatic pick.
Background technology: general pneumatic pick must connect the impact of could working of air compressor input pressure gas, to carry generator, air compressor etc. when constructing in the open air, carry very inconvenient, if the place of construction does not temporarily have power, perhaps to install when connecting inconvenience, pneumatic pick can't use, directly influence construction, and drive with external source of the gas, the frequency of impact and the dynamics of pneumatic pick are restricted, and can not adapt to the requirement of some construction.
Summary of the invention: at the deficiency that existing pneumatic pick must external source of the gas just can be worked, the utility model provides a kind of compact conformation, the portable power pneumatic pick of the use that can work independently.
The utility model comprises head and is located at the drill sleeve of bottom, the top of head connects cylinder body, cylinder jacket is fixed in the cylinder body, between the outer wall of cylinder jacket and the inwall of cylinder body closed cavity is arranged, and the outer wall of cylinder jacket is provided with through hole and is communicated with this closed cavity, the head of impulsion cylinder places cylinder sleeve to move cooperation, above cylinder body, be connected with the minitype motivation source, the output shaft in this minitype motivation source is by the eccentric upper end that connects connecting rod of transmission mechanism, the lower end of connecting rod and place the piston block of cylinder sleeve to connect and compose the piston reciprocating action unit.
During use, utilize the minitype motivation source to drive piston block reciprocating action in cylinder sleeve, make gas compression-expansion repeatedly, and then make the impulsion cylinder knee-action, impact the bore bit that is installed in the drill sleeve and carry out work.Compact conformation of the present utility model need not connect the air compressor use that promptly can work independently, and portably uses flexiblely, and frequency of impact and dynamics are higher.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the main structure schematic diagram of embodiment.
Embodiment: as shown in the figure, drill sleeve 9 is located at head 8 bottoms, during use bore bit can be installed.The top of head 8 connects cylinder body 1, and cylinder jacket 2 is fixed in the cylinder body 1, between the inwall of the outer wall of cylinder jacket 2 and cylinder body 1 closed cavity 4 is arranged, and the outer wall of cylinder jacket 2 is provided with through hole 10 these closed cavities 4 of connection.The head of impulsion cylinder 3 places cylinder sleeve 2 to move cooperation, above cylinder body 1, be connected with minitype motivation source 5, the output shaft in this minitype motivation source 5 is by the eccentric upper end that connects connecting rod 6 of transmission mechanism, the lower end of connecting rod 6 and place the piston block 7 of cylinder sleeve 2 to connect and compose the piston reciprocating action unit.
The transmission mechanism of present embodiment is the gear graduation transmission mechanism, and the eccentric position that roller bolt 11 is located on the final stage gear 12 is connected with connecting rod 6 upper ends, and also available certainly other structure is connected with connecting rod 6, as bent axle.In the course of the work, connecting rod 6 drives piston blocks 7 and moves back and forth, and when piston block 7 downwards the time, the gas in the cylinder sleeve 2 is compressed, and portion gas is compressed into closed cavity 4 by through hole 10, and impulsion cylinder 3 is driven to down impact.When piston block 7 makes progress, the gas of impulsion cylinder 3 tops expands and forms negative pressure, Compressed Gas in the closed cavity 4 enters in the cylinder sleeve 2 of impulsion cylinder 3 lower head by through hole 10, move on the impulsion cylinder 3, impulsion cylinder 3 high-frequency perseverations impact the bore bit that is installed in the drill sleeve 9, make pneumatic pick work.In practice, minitype motivation source 5 can be gasoline engine or motor, also can cooperate by arrangement of clutch between minitype motivation source 5 and transmission mechanism, pneumatic pick is suspended when impacting need not close minitype motivation source 5, avoid carrying out frequent starting, use control also more convenient.
