DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] An adjustable electric pick, such as Figures 1 to 7As shown, it includes a shell 1, one end of which is fixed with a plate body 27 by screws, a pick head assembly is installed at the bottom of the shell 1, and a driving member for driving the pick head assembly is installed on the top of the shell 1, and the driving member includes a driving motor 6 and an eccentric disk 9, the driving motor 6 is fixed to the outer wall of one side of the plate body 27 by screws, and the eccentric disk 9 and the output end of the driving motor 6 are connected by a coupling, and the inner wall of the through hole opened on the surface of the eccentric disk 9 is threadedly connected with a threaded column 16, the inner wall of the through hole is slidably connected with a slider 15, and the slider 15 and the threaded column 16 are threadedly connected, a limiting plate 13 is welded between the inner walls on both sides of the shell 1, and a reciprocating rod 12 is slidably connected to the surface of the limiting plate 13, and a swing arm 8 is rotatably connected between one end of the reciprocating rod 12 and the slider 15, and the other end of the reciprocating rod 12 is rotatably connected with a rolling ball 11.

[0031] By providing a driving motor 6, the eccentric disk 9 can be driven to rotate, and the swing arm 8 is used to convert the circular motion of the eccentric disk 9 into the reciprocating motion of the reciprocating rod 12 along the limit plate 13. When the reciprocating rod 12 makes a progressive motion, the ball 11 at the end of the reciprocating rod 12 can be used to drive the pick head assembly, so that the pick head assembly can break the object under the drive of the ball 11. When the hammering depth of the pick head assembly needs to be adjusted, the slider 15 is made to slide along the through hole opened on the surface of the eccentric disk 9 by rotating the threaded column 16, and the position of the slider 15 relative to the eccentric disk 9 is adjusted, and the farthest position of the ball 11 moving along the limit plate 13 is adjusted. The distances driven by the ball 11 to move the pick head assembly are different, so that the impact force of the pick head assembly can be adjusted within a certain range.

[0032] Furthermore, the pick head assembly includes a mounting seat 14 and a bevel gear 24, the mounting seat 14 is fixed between the inner walls on both sides of the shell 1 by screws, and the bevel gear 24 is rotatably connected to the mounting seat 14 through a bearing 25, a support rod 23 is fixed to the outer wall of one side of the bevel gear 24 by screws, and the outer wall of the support rod 23 is slidably connected to the top plate 21, and a hammer rod 26 is fixed to the bottom of the top plate 21 by bolts, and the same spring 22 is fixed between the top of the bevel gear 24 and the bottom of the top plate 21 by a clamping manner.

[0033] When the ball 11 makes a forward motion, it hammers the surface of the top plate 21. The force transmission effect enables the hammer rod 26 to impact and crush the object under the drive of the top plate 21. When the ball 11 makes a return motion, the rebound force of the spring 22 enables the hammer rod 26 to reset.

[0034] Furthermore, a side plate 19 is fixed between the inner walls on both sides of the shell 1 by screws, and the outer wall on one side of the side plate 19 is rotatably connected to a bevel gear 20, and the bevel gear 20 and the bevel gear 24 are meshed with each other, and the outer wall of the bevel gear 20 and the outer wall of the eccentric disk 9 are respectively fixed with a pulley 2 18 and a pulley 7 by pins, and the pulley 2 18 and the pulley 7 are transmitted by a synchronous belt 17.

[0035] By utilizing the transmission effect of the synchronous belt 17, the driving motor 6 drives the eccentric disk 9 to rotate while driving the bevel gear 20 to rotate. The bevel gear 20 drives the bevel gear 24 to rotate during the rotation process, so that the hammer rod 26 can crush the object by rotating while reciprocating. This improves the crushing effect on the object.

[0036] Furthermore, a protective shell 5 is fixed to an outer wall of one side of the plate body 27 by bolts, and a dustproof and heat dissipation net 4 is welded to one end of the protective shell 5 .

[0037] The protective shell 5 can cover the driving motor 6 to protect the driving motor 6 , and the dustproof heat dissipation net 4 can facilitate heat dissipation of the driving motor 6 during operation.

[0038] Furthermore, a controller 3 is fixed to the outer wall of the shell 1 by screws, and the controller 3 and the driving motor 6 are electrically connected. A switch button is provided on the controller 3 to control the start and stop of the driving motor 6.

[0039] Furthermore, handles 2 are fixed to the outer walls on both sides of the shell 1 by screws. During operation, the handles 2 are held by the hands, so that the entire electric pick can be easily controlled and operated.

[0040] Furthermore, a sealing plate 10 is threadedly connected to one end of the housing 1. When the position of the slider 15 relative to the eccentric disk 9 needs to be adjusted, the sealing plate 10 is removed from the housing 1 to facilitate rotating the threaded column 16 to adjust the position of the slider 15.

[0041] Working principle: When in use, hold the handle 2 with your hand, then start the start button on the controller 3. After starting, the drive motor 6 drives the eccentric disk 9 to rotate, and uses the swing arm 8 to convert the circular motion of the eccentric disk 9 into the reciprocating motion of the ball 11. The ball 11 impacts the top plate 21 during the process motion, so that the hammer rod 26 breaks the object during the movement. When the crushing depth of the hammer rod 26 needs to be adjusted, the threaded column 16 is rotated to make the slider 15 move along the through hole opened on the surface of the eccentric disk 9, and the farthest moving position of the ball 11 is adjusted, thereby adjusting the impact force of the hammer rod 26.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
