Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from fig. 1 to 3, the invention includes two vertical plates 1 placed at intervals in the front and back, a horizontal rotating shaft 2 capable of moving left and right is arranged between the two vertical plates 1, two ends of the rotating shaft 2 respectively penetrate through and extend out of the corresponding vertical plates 1, a connecting rod 3 capable of rotating along with the rotating shaft 2 is fixed in the middle of the rotating shaft 2, a hammer 4 is fixed at the other end of the connecting rod 3, a ratchet wheel 5 is respectively fixed at the front and back ends of the rotating shaft 2, a transverse plate 6 is arranged below each ratchet wheel 5, a plurality of pawls 7 matched with the corresponding ratchet wheel 5 are arranged on the upper end surface of each transverse plate 6, the rotating shaft 2 moves left to drive the ratchet wheels 5 to move on the plurality of pawls 7 and rotate the ratchet wheels 5 counterclockwise, the rotating shaft 2 moves right to drive the ratchet wheels 5 to slide on the.

In order to realize better supporting effect, two risers 1 are equipped with a mobilizable dolly 8, and two risers 1 highly be greater than connecting

rod

3 and 4 length of tup, and the length that highly be greater than connecting rod 3 through

riser

1 and 4 tups satisfies can not make tup 4 contact bottom surface on dolly 8 under the pivoted condition of connecting rod 3.

In order to realize that the rotating shaft 2 can move left and right, a horizontal through groove 9 is formed in the vertical plate 1, the front end and the rear end of the rotating shaft 2 respectively penetrate through the front through groove 9 and the rear through groove 9, and the technical requirement that the rotating shaft 2 can move left and right is met through the arrangement of the through grooves 9.

In order to realize the driving of the rotating shaft 2, two L-shaped rods 10 which are symmetrical about the central plane of the rotating shaft 2 in the front-back direction are arranged on the part of the rotating shaft 2, which is arranged between the two transverse plates 6, the transverse rod ends of the L-shaped rods 10 are fixedly connected with the rotating shaft 2, the vertical rod ends extend out of the corresponding vertical plate 1 and are fixed with a stepping motor 11, a gear 12 is connected onto the stepping motor 11, a rack 13 meshed with the gear 12 is fixed on the upper end face of the vertical plate 1, and the gear 12 is driven to be meshed with the rack 13 through the rotation of the stepping motor 11, so that the rotating shaft 2 is.

In order to realize that the ratchet wheel 5 can drive the ratchet wheel 5 to rotate when the ratchet wheel 5 moves forwards, the upper end surface of the transverse plate 6 is provided with an installation groove 14, the left ends of the plurality of the ratchet wheels 7 are hinged in the installation groove 14 through a pin shaft, the right ends of the plurality of the ratchet wheels 7 are provided with a pressure spring 15, a rope 16 is sleeved in the middle of the pressure spring 15, the fact that the ratchet wheels 7 can only swing in the right side area is realized through the cooperation of the rope 16 and the pressure spring 15, and therefore the ratchet wheel 5 can be driven to rotate by the ratchet wheels 7 when the.

The specific working process of the invention is as follows: when the device is used, the trolley 8 is moved to one side of a stone to be crushed, the stroke of the stepping motor 11 is set according to the size of the stone, the stepping motor 11 is opened after the completion, the rotation of the stepping motor 11 drives the gear 12 to rotate anticlockwise, the gear 12 is meshed with the rack 13, the rack 13 is fixed, the stepping motor 11 is moved to the left under the condition that the gear 12 rotates, and the leftward movement of the stepping motor 11 drives the rotating shaft 2 to move leftward through the L-shaped rod 10.

Parallel translation's in-process left in pivot 2, because the hindrance effect of pawl 7 realizes that 5 movements of ratchet receive to block this moment, and this blocks effect and realizes 5 anticlockwise rotations of ratchet, and 5 anticlockwise rotations of ratchet drive pivot 2 rotations, and the rotation of pivot 2 drives connecting rod 3 and rotates, and the rotation of connecting rod 3 drives tup 4 and carries out the striking to the stone.

After knocking is completed, under the set formation of the stepping motor 11, the stepping motor 11 starts to rotate reversely and drives the rotating shaft 2 to move left and right, at the moment, the ratchet wheel 5 slides on the pawl 7, the left side of the pawl 7 is hinged with the right side and is provided with the pressure spring 15 and the rope 16, so that the plurality of pawls 7 can be sequentially extruded downwards when the ratchet wheel 5 moves rightwards, the technical effect that the ratchet wheel 5 does not rotate and only moves is realized, and after the stepping motor 11 returns to the initial position, the next knocking is started again.

This device moves left with crossing pivot 2, and ratchet 5 and the cooperation of a plurality of pawls 7 realize that ratchet 5 can drive pivot 2 and drive tup 4 through connecting rod 3 and carry out hitting of stone when clockwise rotating, and when pivot 2 moved right, pawl 7 was not giving ratchet 5 power, realized that tup 4 wholly moved right for tup 4 breaks away from with the stone, hits to beat for next time and makes preparation.

The effectual in-process of beating the stone of having avoided beating through the back-and-forth movement of pivot 2, the stone hinders tup 4 to lead to tup 4 can not be complete rotate the round.
