[0002] When the splitter works, it is necessary to close the splitter blades on both sides and press them against the splitter wedge so as to insert them into the drilled holes. After the work is completed, it is necessary to separate the splitter blades from the splitter wedge and apply lubricating oil between the splitter blades and the splitter wedge. Currently, the traditional method is to stack the splitter blades against the splitter wedge with a spiral spring. The defect of this method is that when separating the splitter blades from the splitter wedge and applying lubricating oil between the splitter blades and the splitter wedge, the elastic force of the spring needs to be overcome, and the operation is extremely inconvenient. Moreover, there is a risk of accidental reset and rebound of the spring, and the splitter blades may pinch the hand, causing injury.

[0003] Based on this, the utility model provides a novel reset mechanism for a rock splitter to solve the problems of inconvenient operation and the risk of pinching the hand by the splitter blades when separating the splitter blades from the splitter wedge. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides a novel reset mechanism for a rock splitter. To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A novel reset mechanism for a rock splitter includes a splitting oil cylinder. A front cover of the splitter is arranged at the front end of the splitting oil cylinder. A splitter wedge penetrates through the front cover of the splitter, and the splitter wedge is connected to the splitting oil cylinder through a pin shaft; Splitting machine cracking blades are respectively arranged on both sides of the splitter wedge and penetrate through the front cover of the splitter. A reset assembly is arranged at the connection part of the fixing part of the splitter cracking blades and the front cover of the splitter, which is fixed on the front cover of the splitter.

[0006] Preferably, the reset assembly includes a side cover of the splitter, a cracking blade closing oil cylinder and a closing oil cylinder pressing plate. The output end of the cracking blade closing oil cylinder is connected to the end of the splitter cracking blade. The cracking blade closing oil cylinder penetrates through the side wall of the side cover of the splitter and the front cover of the splitter. The closing oil cylinder pressing plate fixes the cracking blade closing oil cylinder on the side cover of the splitter, and the side wall of the side cover of the splitter is fixedly connected to the side wall of the front cover of the splitter.

[0007] Preferably, a cracking blade cushion block is inserted into the contact surface between each splitter cracking blade and the front cover of the splitter.

[0008] Preferably, the side wall of the side cover of the splitter is connected to the side wall of the front cover of the splitter by screws.

[0009] Preferably, a through hole is provided on the front cover of the splitter, and the through hole is in a cross structure.

[0010] Preferably, the wedge block of the splitter passes through the vertical groove body of the cross structure, and the cracking pieces of the splitter are respectively arranged in the horizontal groove bodies on both sides of the vertical groove body.

[0011] Preferably, concave holes matching with the cracking piece closing oil cylinder are provided on both side walls of the front cover of the splitter.

[0012] Preferably, a first fixing hole is provided outside the concave hole, a second fixing hole is provided on the side cover of the splitter, and the side cover of the splitter and the front cover of the splitter are fixed through the first fixing hole and the second fixing hole.

[0013] Preferably, the splitting oil cylinder (1) and the front cover (2) of the splitter are connected by threads.

[0014] In summary, due to the adoption of the above technical solutions in the present utility model, the present utility model has the following technical effects:

[0015] 1. By controlling the telescopic movement of the oil cylinder, the present utility model realizes the opening and closing of the cracking piece of the splitter and the wedge block of the splitter: when it is necessary to insert into the hole to expand and crack the rock, the oil cylinder extends, and the cracking piece of the splitter and the wedge block of the splitter are closed, which is more convenient for entering the hole. When it is necessary to separate the splitting piece of the splitter and the wedge block of the splitter to apply lubricating oil, the oil cylinder retracts, and the cracking piece of the splitter and the wedge block of the splitter can be easily separated, and applying lubricating oil is more labor-saving and convenient. The use of a hydraulic oil cylinder instead of a spiral spring solves the problems of the traditional spiral spring, such as inconvenient operation and the risk of accidental reset and rebound of the spring.

[0016] 2. In the original spiral spring reset mode of the present utility model, when it is necessary to apply lubricating oil, a crowbar or a steel plate is used to overcome the elastic force of the spring to pry open the cracking piece of the splitter and the wedge block of the splitter. At this time, the spring is compressed, and there is a force to make the cracking piece of the splitter and the wedge block of the splitter recombine. If the crowbar or the steel plate slips, the cracking piece of the splitter and the wedge block of the splitter may be quickly closed under the thrust of the spring, posing a risk of pinching hands. The solution of the present utility model can avoid the above hidden dangers. BRIEF DESCRIPTION OF THE DRAWINGS

The splitting machine wedge block 3 is connected to the splitting oil cylinder 1 through a pin shaft. Splitting machine cracking pieces 4 are respectively arranged on both sides of the splitting machine wedge block 3 and penetrate through the front cover 2 of the splitting machine. A reset assembly is provided at the connection of the fixed part of the splitting machine cracking pieces 4 fixed on the front cover 2 of the splitting machine. The reset assembly includes a side cover 5 of the splitting machine, a cracking piece closing oil cylinder 6, and a closing oil cylinder pressing plate 7. The output end of the cracking piece closing oil cylinder 6 is connected to the end of the splitting machine cracking piece 4. The cracking piece closing oil cylinder 6 penetrates through the side wall of the side cover 5 of the splitting machine and the front cover 2 of the splitting machine. The closing oil cylinder pressing plate 7 fixes the cracking piece closing oil cylinder 6 on the side cover 5 of the splitting machine. The side wall of the side cover 5 of the splitting machine is fixedly connected to the side wall of the front cover 2 of the splitting machine.

[0022] In one embodiment, a splitting piece spacer 8 is inserted into the contact surface between each splitting piece 4 of the splitter and the front cover 2 of the splitter. The splitting piece spacer 8 is used to separate the splitting piece 4 of the splitter from the front cover 2 of the splitter, preventing the front cover 2 of the splitter from being scratched when the splitting piece 4 of the splitter slides. The side cover 5 of the splitter and the side wall of the front cover 2 of the splitter are connected by screws. The front cover 2 of the splitter is provided with a through hole 9, and the through hole 9 is in a cross shape. The wedge block 3 of the splitter passes through the vertical groove of the cross structure, and the splitting pieces 4 of the splitter are respectively arranged in the horizontal grooves (i.e., the inner hole sliding grooves of the front cover 2 of the splitter) on both sides of the vertical groove.

[0023] In one embodiment, concave holes 10 matching the splitting piece closing oil cylinder 6 are provided on both side walls of the front cover 2 of the splitter. A first fixing hole 11 is provided on the side wall of the front cover 2 of the splitter outside the concave hole 10, and a second fixing hole 12 is provided on the side cover 5 of the splitter. The side cover 5 of the splitter and the front cover 2 of the splitter are fixed through the first fixing hole and the second fixing hole.

[0024] In one embodiment, the splitting oil cylinder 1 and the front cover 2 of the splitter are connected by threads.

[0025] In summary, the working principle of a novel reset mechanism of a rock splitter of the present utility model is as follows: First, the wedge block 3 of the splitter is connected to the splitting oil cylinder 1 through a pin shaft; the front cover 2 of the splitter is tightly connected to the splitting oil cylinder 1 by threads; the splitting piece 4 of the splitter passes through the inner hole sliding groove of the front cover 2 of the splitter for connection, and the splitting piece 4 of the splitter can slide in the inner hole sliding groove of the front cover 2 of the splitter; a splitting piece spacer 8 is inserted into the middle of the contact surface between the splitting piece 4 of the splitter and the front cover 2 of the splitter, which is used to separate the splitting piece 4 of the splitter from the front cover 2 of the splitter, preventing the front cover 2 of the splitter from being scratched when the splitting piece 4 of the splitter slides. The splitting piece closing oil cylinder 6 passes through the matching hole of the side cover 5 of the splitter, and the splitting piece closing oil cylinder 6 is fixed on the side cover 5 of the splitter through the closing oil cylinder pressing plate 7; the side cover 5 of the splitter is tightly connected to the front cover 2 of the splitter by screws. At this time, the piston rod of the splitting piece closing oil cylinder 6 abuts against the splitting piece 4 of the splitter. When the piston rod of the splitting piece closing oil cylinder 6 extends, it will push the splitting piece 4 of the splitter to closely adhere to the wedge block 3 of the splitter; when the piston rod of the splitting piece closing oil cylinder 6 retracts, the splitting piece 4 of the splitter will loosen without an external thrust from the wedge block 3 of the splitter, thereby realizing the separation and clamping of the splitting piece 4 of the splitter. Through the splitting piece closing oil cylinder 6, the splitting piece 4 of the splitter and the wedge block 3 of the splitter can be easily separated, and it is more labor-saving and convenient to apply lubricating oil, solving the risks of spring rebound and pinching hands in the traditional one, and reducing potential safety hazards.

[0026] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
