At the upper rear side of the body 3, the arc-shaped baffle 41 is provided with a sliding cabin 42 that passes through its front end. A baffle 43 is slidably installed in the inner cavity of the sliding cabin 42. The baffle 43 is provided with a ring array of positioning holes 45 that pass through it left and right. The left and right sides of the arc-shaped baffle 41 are provided with docking holes 46 that pass through the inner cavity of the sliding cabin 42. The inner circles of the two docking holes 46 are penetrated by a limiting rod 47, and the limiting rod 47 passes through one of the positioning holes 45. A pull plate 44 is fixedly installed at the front end of the baffle 43, and a pull rod 48 is fixedly installed at the left end of the limiting rod 47.

[0025] When the mining machine body 1 uses the mining head body 3 at the front end of the mining head driving arm 2 to mine, the arc-shaped baffle 41 can be used to prevent ore fragments from splashing. At the same time, when the shielding range needs to be adjusted, the baffle 43 can be extended by pinching the pull plate 44 and pulling it forward, so that a larger range of the mining head body 3 can be blocked. After stretching, the corresponding positioning hole 45 can be aligned with the two docking holes 46 on the left and right, and then the pull rod 48 can be held to insert the limit rod 47 through the right docking hole 46, and then through the corresponding positioning hole 45 and then through the left docking hole 46 to complete the limit fixation of the baffle 43.

[0026] like Figure 3 、 Figure 4 As shown, a snap compartment 471 is provided on the side of the limiting plug rod 47 away from the pull rod 48, and one end of the snap compartment 471 passes through the left side of the arc-shaped baffle 41, and an upper and lower limiting slide plates 472 are slidably installed in the inner cavity of the snap compartment 471, and a V-shaped spring piece 474 is fixedly installed between the opposite surfaces of the two limiting slide plates 472, and the opposite back surfaces of the two V-shaped spring pieces 474 are fixedly installed with inclined snaps 473, and the opposite ends of the two inclined snaps 473 respectively pass through the upper and lower sides of the limiting plug rod 47, and the inclined surface of the inclined snaps 473 faces the side away from the arc-shaped baffle 41, and at the same time, the vertical part of the inclined snaps 473 is in contact with the left side of the arc-shaped baffle 41;

[0027] When the limiting rod 47 completely passes through the left docking hole 46, the two inclined buckles 473 will be squeezed and released by the V-shaped spring piece 474 in the inner cavity of the buckle compartment 471, thereby using the vertical surface to press against the left side of the arc-shaped baffle 41 to complete the left and right direction limitation of the limiting rod 47, thereby effectively avoiding vibration-induced falling off of the limiting rod 47 and improving the stability of the baffle 43 after adjustment. When it is necessary to remove the limiting rod 47, just press the inclined buckle 473 at the same time and pull the limiting rod 47 to the right at the same time to complete the disassembly.

[0028] like Figure 4 、 Figure 5As shown, the spray dust reduction mechanism 5 includes an L-shaped hard plastic water pipe 51 and a water pump 53. The left end of the horizontal part of the L-shaped hard plastic water pipe 51 is fixedly connected to an atomizing nozzle 52. The atomizing nozzle 52 is located in the right side of the gap between the arc baffle 41 and the mining head body 3. The water pump 53 is fixedly installed on the top of the mining head drive arm 2. The output end of the water pump 53 is fixedly connected to a water hose 54. The other end of the water hose 54 is fixedly connected to the bottom end of the vertical part of the L-shaped hard plastic water pipe 51. The input end of the water pump 53 is connected to an external water source. A fixed sleeve is fixedly installed below the outer wall of the vertical part of the L-shaped hard plastic water pipe 51. 55. An extension plate 21 is fixedly mounted on the right side of the mining head drive arm 2. A servo motor 211 is fixedly mounted on the front side of the extension plate 21. A driving gear 212 is fixedly mounted on the output shaft of the servo motor 211. A gear guard 31 is fixedly mounted on the right eccentric portion of the mining head body 3. A driven gear 32 is movably mounted on the right center of the mining head body 3. The gear guard 31 is located above the driven gear 32. The driven gear 32 meshes with the driving gear 212. The fixed sleeve 55 is fixedly mounted on the right eccentric portion of the driven gear 32. An encoder 213 is provided on the top of the servo motor 211.

[0029] When dust reduction is being performed, water from an external source can be injected into the L-shaped hard plastic water pipe 51 through the water supply hose 54 by the water pump 53, and then sprayed into the space between the arc baffle 41 and the mining head body 3 by the atomizing nozzle 52, thereby playing a role in dust reduction. In order to ensure the dust reduction range, the servo motor 211 on the front side of the extension plate 21 can be started to drive the driving gear 212 to rotate. The engagement of the driving gear 212 with the driven gear 32 can drive the driven gear 32 to rotate about the axis of the mining head body 3 by using the fixed sleeve 55, and at the same time, the rotation angle of the driving gear 212 is controlled by the encoder 213, so that the rotation of the driven gear 32 is only one hundred and eighty degrees of the upper half of the mining head body 3 and then reset, so that the reciprocating motion of the atomizing nozzle 52 sprays water to reduce dust, thereby improving the dust reduction range for dust, and the tops of the driven gear 32 and the driving gear 212 can be protected by the gear guard plate 31 to prevent gravel from getting stuck, thereby ensuring the stability of operation.

[0030] The following is a detailed description of the working principle of the mining machine with a dual-function mining device.

[0031] like Figure 1-5As shown, when the mining machine body 1 is mining with the mining head body 3 at the front end of the mining head driving arm 2, the arc-shaped baffle 41 can be used to prevent the ore fragments from splashing. At the same time, when it is necessary to adjust the shielding range, the baffle 43 can be extended by pinching the pull plate 44 and pulling it forward, so that a larger range of the mining head body 3 can be blocked. After stretching, the corresponding positioning hole 45 can be aligned with the two docking holes 46 on the left and right, and then the pull rod 48 can be held to insert the limit rod 47 through the right docking hole 46 and through the corresponding After the positioning hole 45 is formed, it passes through the left docking hole 46 to complete the limit fixation of the baffle 43. At the same time, when the limit rod 47 completely passes through the left docking hole 46, the two inclined buckles 473 are squeezed by the V-shaped spring pieces 474 in the inner cavity of the buckle cabin 471 and released to bounce up, thereby using the vertical surface to press the left side of the arc-shaped baffle 41 to complete the left and right direction limit of the limit rod 47, thereby effectively preventing the limit rod 47 from falling off left and right due to vibration, and improving the stability of the baffle 43 after adjustment. When the limit rod 47 needs to be removed, just press The lower bevel buckle 473 is pulled out simultaneously with the limit rod 47 to the right to complete the disassembly. When performing dust reduction, the external water source can be injected into the L-shaped hard plastic water pipe 51 through the water hose 54 by the water pump 53, and sprayed into the space between the arc baffle 41 and the mining head body 3 through the atomizing nozzle 52 to play a role in dust reduction. In order to ensure the dust reduction range, the servo motor 211 on the front side of the extension plate 21 can be started to drive the driving gear 212 to rotate, and the driven gear 32 can be driven by the engagement of the driving gear 212 with the driven gear 32. 32 uses the fixed sleeve 55 to control the L-shaped hard plastic water pipe 51 to rotate about the axis of the mining head body 3, and at the same time uses the encoder 213 to control the rotation angle of the driving gear 212, so that the rotation of the driven gear 32 is only 180 degrees of the upper half of the mining head body 3 and then resets, realizing the reciprocating motion of the atomizing nozzle 52 to spray water and reduce dust, thereby increasing the dust reduction range, and the tops of the driven gear 32 and the driving gear 212 can be protected by the gear guard plate 31 to prevent gravel from getting stuck, thereby ensuring the stability of operation.
