In other embodiments, the cutter 100 may be used to cut after the percussion drill 200 has been used to impact the mineral source. It will be appreciated that when only the cutter 100 is used to cut the source directly, since the cutter 200 is cut into the source, it can only cut one way towards the source for each operation, and if the source is cut, it is necessary to cut the source multiple times at multiple angles to make the large ore fall off the source, and in addition, the depth of the cutter 100 cut into the source is limited, and the efficiency of mining the source is difficult to improve.

Referring to fig. 2, in a further embodiment, the hammer drill 200 is a hydraulic hammer drill, the cutter 100 includes a dicing saw 105, and the dicing saw 105 performs cutting by rotating. The dicing saw 105 has a large cutting force under the condition of rotation, and thus can effectively cut the mineral resources to destroy the internal structure of the mineral resources. The dicing saw 105 is a circular dicing saw. It will be appreciated that the direction of rotation of the saw 105 is at an angle to the face of the source, preferably the direction of rotation of the saw 105 is between 60 and 90 degrees to the face of the source, that is the saw 105 cuts the face of the source at an angle of 60 to 90 degrees to the face of the source.

In a further embodiment, the main body apparatus 10 is provided with a robot arm 300, the robot arm 300 is capable of rotating at multiple angles, the hammer drill 200 is fixed to the robot arm 300 so that the hammer drill 100 can perform impacts in upward, downward, forward, leftward and rightward directions, and the cutter 100 is fixed to the robot arm 300 so that the cutter 300 can perform cutting in upward, downward, forward, leftward and rightward directions.

In a further embodiment, the main body device 10 further comprises a control device 400, and the control device 400 is used for controlling the percussion drill 200 to perform percussion and controlling the cutter 100 to perform cutting. The control device 400 is connected to the hammer drill 200 and the cutter 100 to control the hammer drill 200 and the cutter 200. The control device is also connected with the walking device 20 and the transportation device 40 so as to control the walking device 20 to walk and control the transportation device 400 to transport ores.

In a further embodiment, the control device 400 controls the impact drill 200 to impact at a first preset frequency and a preset force, where the first preset frequency is the number of times that the impact drill 200 impacts within a preset time; the control device 400 controls the cutter 100 to rotate at a second preset frequency and a preset linear speed for cutting, wherein the second preset frequency is the number of times that the cutter 100 cuts within the preset time; the first preset frequency is 5-100 times of the second preset frequency. So that the ore source cut by the cutter 100 is impacted by the impact drill 200 to form an ore block. Typically, the second predetermined frequency of cutting of the mineral source by the cutter 100 is less than the first predetermined frequency of impact of the impact drill 200 against the mineral source, i.e., the number of times the mineral source is cut by the cutter 100 within a predetermined time is less than the number of times the mineral source is impacted by the impact drill 200. In the present embodiment, the first preset frequency is set to 5 to 100 times the second preset frequency, so that the efficiency of the percussion drill 200 and the cutter 100 working together can be improved. In a preferred embodiment, the first predetermined frequency is 10-50 times the second predetermined frequency. In a more preferred embodiment, the first predetermined frequency is 10-20 times the second predetermined frequency. It is understood that, when the dicing saw 105 is a circular dicing saw, when the diameter of the circular dicing saw is determined, the "control device 400 controls the cutter 100 to rotate at the second preset frequency and the preset linear velocity to perform cutting" may further be: the control device 400 controls the cutter 100 to rotate at a second preset frequency and a preset rotation speed for cutting.

In a further embodiment, the control device 400 controls the cutter 100 to cut the mineral source at a first time, the control device 400 controls the percussion drill 200 to strike the mineral source at a second time, the first time precedes the second time, and the time interval between the first time and the second time is less than 5 min. That is to say, in the mining machine 1, the cutter 100 is controlled to cut the mineral resources first, and the impact drill 200 is controlled to impact the mineral resources, and the method has the advantages as described above, but in this embodiment, the first time and the second time interval are set so that the matching efficiency of the cutter 100 and the impact drill 200 is higher, and if the cutter 100 cuts the mineral resources first and then the impact drill 200 is controlled to impact the mineral resources for a long time, the mining time is prolonged, and the working efficiency of the matching of the cutter 100 and the impact drill is greatly reduced. In a preferred embodiment, the time interval between the first time and the second time is less than 2 min. In a further embodiment, after the control device 400 controls the cutter 100 to cut a first location of the mineral source at a first time, the control device 400 controls the percussion drill 200 to strike a second location of the mineral source at a second time, wherein the second location is less than 2m from the first location. That is, the location at which the impact bur 200 impacts the mineral source may not be spaced too far from the location at which the cutter 100 cuts the mineral source, otherwise the efficiency of the cutter 100 and impact bur 200 in cooperation may be reduced because the area at which the cutter 100 cuts the mineral source, i.e., the area of damage to the internal structure of the mineral source, is limited, and when the first and second locations are spaced too far apart, the mineral source in the second location may not be damaged by the cutter 100, and then impacting the impact bur 200 in the second, more remote location may not achieve the desired effect.

In a further embodiment, the control device 400 further sets the first preset frequency, the preset force, the second preset frequency and the preset linear speed according to the environmental parameter and/or the mineral source parameter of the mineral source. The environmental parameters comprise one or more of temperature, humidity and dust density, and the mineral source parameters comprise one or more of hardness, viscosity and water content of the mineral source. The dust density refers to the mass of dust particles per unit volume of air. It will be appreciated that when the mining machine 1 mines a mineral source within a roadway, the environmental and source parameters at which the source is located have a significant impact on the safety and efficiency of the percussion drill 200 and cutter 100 in operation. The mineral source parameters are important criteria for the operating parameters of the cutter 100 and the impact drill 200, for example, when the hardness of the mineral source is high, the impact drill 200 is required to impact with high force, or the cutter 100 is required to cut at a high preset linear speed, and the viscosity and the water content of the mineral source are also important factors for adjusting the operating parameters of the impact drill 200 and the cutter 100. The environmental parameters have an important influence on the environmental safety of the mining machine 1, for example, when the mining machine 1 is in operation and the temperature of the mineral source is too high and the dust density is too high, if the percussion drill 200 is impacted at a first preset frequency and a preset force, the cutter 100 still cuts at a second preset frequency and a preset linear speed, and the risk of dust explosion may occur. Therefore, in this embodiment, the control device 400 sets the first preset frequency, the preset force, the second preset frequency and the preset linear speed according to the environmental parameter and/or the mineral source parameter where the mineral source is located, so that the working safety of the mining machine 1 can be ensured while the mining machine has high efficiency.

The hardness, viscosity and water content of the ore source can be detected through manual sampling, and corresponding monitoring elements can be installed in the main body device 10 for real-time monitoring.

In one embodiment, two of the percussion drills 200 are disposed on one of the cutters 100, and the two percussion drills 200 are disposed on both sides of the cutter 100, and when the cutter 100 cuts the cutting saw 105 in the mine, the percussion drills 200 on both sides strike the mine from both sides of the cutting saw 100, respectively. Two impact drills 200 impact on both sides of the cutter 100, further improving mining efficiency.

In a further embodiment, a distance sensor (not shown in the figures) is disposed on each of the percussion drill 200 and the cutter 100, the distance sensor is connected to the control device 400, and when the distance sensor monitors that the distance between the percussion drill 200 and the cutter 100 is smaller than a preset distance, the control device 400 controls the percussion drill 200 and the cutter 100 to be separated until the distance between the two is greater than or equal to the preset distance.
