An embodiment of the present invention, a heading machine 100, is described below with reference to fig. 1 to 5.

Example one

As shown in fig. 1 and 2, the present embodiment provides a heading machine 100 including an apparatus body 110, a crawler type traveling part 120, a blade part 130, and a support part 140. The crawler belt 120 is provided at the bottom of the apparatus body 110, and it is understood that the crawler belt 120 in the heading machine 100 is a portion that contacts the ground. The equipment body 110 is movable or rotatable by the crawler type traveling unit 120, in other words, when the heading machine 100 travels in a coal mine tunnel, the equipment body 110 can advance, retreat, or turn by the crawler type traveling unit 120. Further, the crawler track 120 has a contact surface 121, and specifically, the crawler track 120 includes a track and a driving member capable of driving the track to run. The lower surface of the crawler belt is a contact surface 121 contacting the ground. During the advancing process of the heading machine 100, the track in the track type traveling part 120 continuously runs, but the contact surface 121 is always the lower surface of the track which is in direct contact with the ground. It is noted that the shape of the contact surface 121 may be square or any other shape.

Further, one end of the blade portion 130 is rotatably connected to the apparatus body 110, that is, the blade portion 130 is rotatable with respect to the apparatus body 110, and specifically, the blade portion 130 may be rotatably connected to the apparatus body 110 by a first shaft, in other words, the blade portion 130 may be rotatable about an axis of the first shaft. Typically, the heading machine 100 further includes a cutting part 170, the cutting part 170 is disposed at one end of the apparatus body 110 near the blade portion 130, and the cutting part 170 is located above the blade portion 130. After the cutting part 170 cuts the rock mass of the tunnel face, the rock mass begins to peel off and fall off, the dropped rock mass is accumulated below the cutting part 170, and the shovel plate part 130 is installed below the cutting part 170, so that the shovel plate part 130 can cut and shovel the rock mass, and can also play a role in receiving materials, and the materials can be conveniently and subsequently conveyed out.

Further, one end of the support portion 140 is rotatably connected to the apparatus body 110, that is, the support portion 140 is rotatable with respect to the apparatus body 110, and specifically, the support portion 140 may be rotatably connected to the apparatus body 110 by a second shaft, that is, the support portion 140 may rotate about an axis of the second shaft. The heading machine 100 includes an upper support provided at the top of the apparatus body 110 and a lower support provided at the bottom of the apparatus body 110, and it is understood that the lower support is the support 140.

Since the shovel portion 130 is closer to the tunnel face than the supporting portion 140, the shovel portion 130 is located at the front end of the heading machine 100, the supporting portion 140 is located at the rear end of the heading machine 100, the first angle 132 is an approaching angle, and the second angle 142 is a departing angle. Since both the shovel plate part 130 and the support part 140 can rotate relative to the apparatus body 110, by limiting the angular ranges of the first angle 132 and the second angle 142, on one hand, the lengths and the rotational ranges of the shovel plate part 130 and the support part 140 can be restricted, and interference with other parts of the heading machine 100 can be avoided; on the other hand, by increasing the ranges of the first angle 132 and the second angle 142, the heading machine 100 may have a larger approach angle and departure angle, so that when the heading machine 100 runs in a coal mine tunnel, especially on an uphill slope or a downhill slope, the possibility that the front or rear part of the equipment interferes with the ground can be greatly reduced, the passing performance in the coal mine tunnel can be improved, and the heading machine 100 can adapt to more complicated geological conditions.

In addition, when the oil tank 151 is directly connected to the device body 110, the oil tank 151 may be detachably connected to the device body 110, so that the oil tank 151 may be conveniently repaired or replaced.

Further, an oil pump 152 is provided on the apparatus body 110, one end of a first oil pipe 153 is connected to the bottom of the oil tank 151, and the other end of the first oil pipe 153 is connected to the oil pump 152. Specifically, the bottom of the oil tank 151 is provided with an oil outlet 1511, and the end of the first oil pipe 153 is hermetically connected with the oil outlet 1511. The oil pump 152 can draw oil in the oil tank 151, that is, the oil in the oil tank 151 enters the oil pump 152 through the first oil pipe 153, and then is conveyed to the hydraulic elements through the oil pump 152, and the hydraulic elements can drive the shovel plate part 130 and the supporting part 140 to rotate, and can also drive the crawler traveling part 120 to operate.

By arranging the oil tank 151 at the top of the equipment body 110 and connecting the end of the first oil pipe 153 with the bottom of the oil tank 151, on one hand, the position of the oil tank 151 is improved, and oil can flow out of the oil tank 151 more easily; on the other hand, the oil surface of the heading machine 100 can be ensured not to be lower than the oil outlet 1511 when the heading machine is on an uphill slope or a downhill slope, the oil pump 152 cannot be emptied in a working environment with a large gradient, and the hydraulic system 150 can still provide power, so that the use reliability of the hydraulic system 150 is improved. In addition, the method is beneficial to improving the passing property of the heading machine 100 in the coal mine tunnel, and the heading machine 100 can adapt to more complicated geological conditions.

The hydraulic motor 161 and the speed reducer 162 are both disposed on the device body 110, specifically, the hydraulic motor 161 and the device body 110 may be detachably connected, and the speed reducer 162 and the device body 110 may also be detachably connected, so that the mounting and the dismounting are convenient, and the maintenance and the replacement of components are facilitated.

Further, reduction gear 162 is connected for the transmission with hydraulic motor 161, and reduction gear 162 can be connected with the transmission shaft transmission, and the transmission shaft drives crawler-type walking portion 120 operation, through setting up reduction gear 162, when the transmission moment of torsion, can match suitable rotational speed.

It should be noted that increasing the power of the hydraulic motor 161 or increasing the reduction ratio of the reducer 162 can enhance the driving capability of the heading machine 100, which is beneficial to improving the trafficability in the coal mine roadway, and the heading machine 100 can adapt to more complex geological conditions. Specifically, the reducer 162 may be a gear reducer 162, the gear reducer 162 includes a driving gear and a driven gear, the driving gear is in transmission connection with the hydraulic motor 161, the driven gear is in transmission connection with the transmission shaft, and the driving gear and the driven gear are engaged with each other, since the number of teeth of the driven gear is divided by the gears of the driving gear to obtain a reduction ratio, it may be considered to increase the number of teeth of the driven gear to improve the reduction ratio of the reducer 162.

Example four

As shown in fig. 1, 2 and 4, in the first embodiment, the crawler-type traveling unit 120 further includes a first crawler belt 122 and a second crawler belt 123. The first crawler 122 is connected with the second crawler 123, and it can be understood that the first crawler 122 and the second crawler 123 form a crawler, which is beneficial to widening the crawler and reducing the ground contact pressure of the heading machine 100. Ground contact pressure refers to the vertical load per unit area of an object in contact with the ground. The ground pressure directly determines the stability and the trafficability characteristic of the machine in the driving process, and the possibility of machine sinking is greatly reduced when the heading machine 100 drives at a position with softer texture in a coal mine tunnel by reducing the ground pressure.
