Description

Technical Field

[0001] The utility model relates to the technical field of mining mechanical hammers, in particular to a mining mechanical hammer with an auxiliary positioning structure. Background Art

[0002] Currently in mining, mechanical equipment such as hydraulic breakers are needed to break rocks on the ground. The power source of the hydraulic breaker is the pressure oil provided by the pump station of the excavator or loader. It can more effectively clean floating stones and soil in rock crevices during the excavation of the building foundation.

[0003] For example, the utility model with application number CN202222542033.1 discloses a hydraulic mining hammer, which uses a gas-liquid composite cylinder to increase the striking energy of the hammer core, that is, pressure oil is used to act on the piston surface of the rod chamber to lift the hammer core, and at the same time, the compressed gas in the rodless chamber is compressed. The compressed gas in the rodless chamber releases the pressure and acts on the piston and the gravity of the hammer core, accelerating the descent. Since the lifting of the hammer core of the hydraulic mining hammer completely uses pressure oil to drive the lifting cylinder, the lifting height of the hammer core can be adjusted steplessly, thereby ensuring the requirements of energy saving and environmental protection, and meeting the purpose of green mining. However, in the actual use of this type of hydraulic mining hammer, it is inconvenient to assist in positioning the lower end of the mechanical hammer, resulting in the problem that the lower end of the mechanical hammer may be deflected due to vibration during the reciprocating hammering process.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a mining mechanical hammer with an auxiliary positioning structure is provided. Utility Model Content

[0008] Furthermore, a dust reduction assembly is provided on the top of the connecting plate, and the dust reduction assembly includes a piston plate, a one-way valve and a filter cover. The piston plate is slidably connected to the inside of the limiting cylinder, and a one-way valve is arranged at one end of the bottom of the limiting cylinder, and a filter cover is sleeved on the outer side of the one-way valve.

[0009] Furthermore, the piston plate is fixedly connected to the fixing rod, and the fixing rod is slidably connected to the limiting cylinder.

[0010] Furthermore, the dust reduction component also includes a one-way valve 2 and a connecting pipe. The other end of the bottom of the limiting cylinder is connected to the one-way valve 2, and the top of the one-way valve 2 is connected to the connecting pipe.

[0011] Furthermore, the dust reduction assembly also includes a water tank and a spray head. The end of the connecting pipe is provided with a water tank, and the bottom outer end of the water tank is provided with a spray head.

[0014] The utility model provides a mining mechanical hammer with an auxiliary positioning structure, which has the following beneficial effects:

[0015] 1. The utility model can make the stabilizing plate fit with the ground before crushing by setting the positioning assembly, so that it can judge whether the breaker hammer body is vertical according to the fit of the stabilizing plate, so as to adjust the angle of the breaker hammer, and avoid affecting the subsequent crushing effect due to the skewness of the breaker hammer. In addition, during the crushing process, the spring can be used to squeeze the limiting cylinder, so that the connecting plate can press the stabilizing plate through the support to increase the friction between it and the ground, so that the limiting sleeve can limit the lower end of the breaker hammer body to guide it, further avoiding its deflection, thereby improving the subsequent crushing effect;

[0016] 2. The utility model provides a dust reduction component. When the breaker body is moving downward, the fixed rod will also drive the piston plate to move inside the limit cylinder, thereby transporting the air inside the limit cylinder to the inside of the water tank through the one-way valve 2 and the connecting pipe. As the pressure at the upper end of the water tank increases, the internal water will be sprayed out from the spray head, so that the water droplets combine with the dust generated during the crushing to settle it, thereby preventing excessive dust from reducing the quality of the surrounding environment and affecting observation. When the breaker body is recovered, the spring will push the limit cylinder to reset the piston plate. At this time, the external air will be filtered by the filter cover and replenished into the limit cylinder through the one-way valve 1, thereby enabling the dust reduction component to be reused.

Before crushing, it is possible to judge whether the breaker body 1 is vertical according to the fit between the stabilizing plate 307 and the ground, so as to adjust the angle of the breaker body 1 to avoid affecting the subsequent crushing effect due to the tilt of the breaker body 1. The stabilizing plate 307 is annular in plan view, and the bottom of the stabilizing plate 307 is serrated. The spring 302 will squeeze the limiting cylinder 303, so that the connecting plate 304 presses the stabilizing plate 307 through the pillars 306 to increase the friction between it and the ground, so that the limiting sleeve 305 limits and guides the lower end of the breaker body 1 to further avoid its deflection.

[0023] like Figure 2 and Figure 3 As shown, a dust suppression component 4 is arranged on the top of the connecting plate 304, and the dust suppression component 4 includes a piston plate 401, a one-way valve 402 and a filter cover 403.

In the crushing process, the spring 302 squeezes the limiting cylinder 303, so that the connecting plate 304 presses the stabilizing plate 307 through the support 306 to increase the friction between it and the ground, so that the limiting sleeve 305 limits the lower end of the breaker body 1. Then, when the breaker body 1 is in the process of moving downward, The fixing rod 301 will also drive the piston plate 401 to move inside the limiting cylinder 303, thereby transporting the air inside the limiting cylinder 303 to the inside of the water tank 406 through the one-way valve 2 404 and the connecting pipe 405, and as the pressure at the upper end of the water tank 406 increases, the water inside will be sprayed out from the spray head 407.
