[0003] But every splitting machine is split 3-5 holes, and a certain amount of lubricating oil is applied to reduce the friction between the wedge and the wedge, when applying lubricating oil, firstly, ensure that the rock splitting machine is in the state of stopping running and power off, manually separate the two wedges and move away from the wedge, since the traditional two wedges are also provided with reset tension spring, the two wedges can be closed when the wedge retracts after splitting is completed, so it is very laborious to separate the two wedges, and after separation, a brush or other tool is used to directly apply lubricating oil on the contact surface of the wedge and the wedge, which is complicated, and the work load is large, and the work progress is also affected, and the work efficiency is reduced, and when manually applying, if the equipment is suddenly started or an accident occurs, the worker is easily injured, and the life and property safety of the operator cannot be guaranteed. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above problems, the utility model provides a rock splitting machine.

[0005] The utility model is realized through the following technical schemes:

[0006] A rock splitting machine, comprising a cylinder body and a sliding cavity below the cylinder body, two wedges are slidingly connected in the sliding cavity, and a sealing plate connected and fixed with the cylinder body is arranged on both sides of the sliding cavity, a retractable wedge is tightly attached between the two wedges, a plurality of oil outlets are arranged on the contact surface of the wedge and the wedge, the oil outlets are communicated with the oil duct in the wedge, the oil duct is connected with the oil branch pipe which can move synchronously with the wedge, the oil branch pipe extends to the outside of the sliding cavity and is connected with the oil hose, the two oil hoses are connected with the oil main pipe, and the oil main pipe is communicated with the automatic oil injection pump.

[0007] Further, the sealing plate is provided with a through hole for the movement of the oil branch pipe.

[0008] Further, the automatic oil injection pump is connected and fixed with the cylinder body through the support.

[0009] Further, the oil branch pipe is made of stainless steel.

[0010] Alternatively, the diameter of the oil outlet hole can be 2-3 mm.

[0011] Compared with existing technologies, the advantages of this invention are as follows: By creating oil outlet holes, oil channels, and oil hoses on the contact surface between the splitting block and the wedge block, and connecting them to an automatic oil pump, this invention eliminates the need for manual labor to separate the splitting block and apply lubricating oil, reducing cumbersome procedures and workload, and improving work efficiency. It also avoids the safety risks associated with accidental equipment startup that may result from manual application, effectively protecting the life and property safety of operators, and achieving convenient, efficient, and safe lubrication operations.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 , 2 As shown in Figures 3 and 4, a rock splitter includes a cylinder 1 and a sliding cavity 2 at its lower part. Two splitting blocks 5 are slidably connected inside the sliding cavity 2, and sealing plates 4 connected and fixed to the cylinder 1 are provided on both sides of the sliding cavity 2. Retractable wedges 3 are tightly fitted between the splitting blocks 5. Several oil outlet holes 6 are opened on the contact surfaces of the wedges 3 and the splitting blocks 5. The oil outlet holes 6 are connected to the oil delivery channels 7 inside the splitting blocks 5. An oil delivery branch pipe 8 that can move synchronously with the splitting blocks 3 is connected to the upper part of the oil delivery channel 7. The oil delivery branch pipe 8 extends to the outside of the sliding cavity 2 and is connected to the oil delivery hose 9. The two oil delivery hoses 9 converge and are connected to the main oil delivery pipe 10. The main oil delivery pipe 10 is connected to the automatic oil injection pump 11.

[0019] like Figure 2As shown, the blocking plate 4 is provided with a through hole 12 for the movement of the oil supply branch pipe 8 to prevent the oil supply branch pipe 8 from being stuck when moving.

[0020] As shown in the drawings, Figure 1 , 4 The automatic oil injection pump 11 is connected and fixed to the cylinder body 1 through a support 13.

[0021] As shown in the drawings, Figure 2 , 3 The oil supply branch pipe 8 is made of stainless steel.

[0022] As shown in the drawings, Figure 3 The oil hole 6 has a diameter of 2-3mm.

[0023] The implementation principle of the rock splitting machine is as follows:

[0024] When splitting the rock, the wedge 3 and the splitting block 5 are inserted into the pre-formed hole, the cylinder body 1 is started, the wedge 3 is extended, a huge thrust is generated, the two splitting blocks 5 are stretched to both sides, and the rock is split;

[0025] When it is necessary to apply lubricating oil, the automatic oil injection pump 11 is started, the lubricating oil in the automatic oil injection pump 11 is injected into the oil supply main pipe 10, the lubricating oil in the oil supply main pipe 10 enters the oil supply branch pipe 8 through the corresponding oil supply hose 9, and then fills the oil supply channel 7, the lubricating oil in the oil supply channel 7 is extruded by the pressure and flows out of the oil outlet hole 6, and spreads to the contact surface between the splitting block 5 and the wedge 3, and at the same time, the lubricating oil is applied by the wedge 3 which is stretched and contracted, thereby reducing the friction between the wedge 3 and the splitting block 5, and realizing automatic application of the lubricating oil, the process is simple, the work is reduced, the work progress is accelerated, the work efficiency is improved, the operator is prevented from being injured, and the life and property safety of the operator is ensured;
