For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 6 As shown, this embodiment provides a basic base system, including a base 1, a tooth seat 3 and a tooth 4. The top projection of the base 1 is rectangular, and has a length L (X axis), a size of 250 mm; a width W (Y axis), a size of 160 mm; a maximum height H (Z axis), a size of 150 mm. The base 1 has a first end face 14 and a second end face 15 in the length direction, and the front receiving portion 2 and the rear receiving portion 20 are arranged between the first end face 14 and the second end face 15.

[0029] like Figures 2 to 4As shown, a front protrusion 10 is provided on the upper surface 13 of the base 1, and the front protrusion 10 is a trapezoidal structure formed by the upper surface 13 extending in the height direction. The trapezoidal structure includes a first side surface 11 close to the first end surface 14, and a second side surface 12 close to the second end surface 15. The upper surface 13 of the base 1 is inwardly recessed to form a front receiving portion 2 and a rear receiving portion 20, and the front receiving portion 2 and the rear receiving portion 20 are connected in a front-to-back through manner. Most of the front receiving portion 2 is located in the front protrusion 10, and the front receiving portion 2 is an open cylindrical profile, and the front receiving portion 2 has a front center axis m.

[0030] Specifically, the front accommodating portion 2 includes a first accommodating surface 21 and a second accommodating surface 22. The axis of the first accommodating surface 21 and the second accommodating surface 22 is consistent with the front center axis m and the two are arranged at an angle β, and the angle β is 90°. The first accommodating surface 21 is a semicircular arc surface structure with a radius Ra and a size of 50 mm; the second accommodating surface 22 is a toroidal surface structure.

[0031] Specifically, the front center axis m is inclined from low to high from the second accommodating surface toward away from the rear accommodating portion, and the front center axis m forms an angle α with the upper surface 13, which is 40°; the front center axis m forms an angle γ with the length direction of the base, which is 7°.

[0032] Specifically, the rear accommodation portion 20 is in the shape of a straight groove, and has a cross-sectional radius Rb and a rear central axis m1 . The cross-sectional radius Rb is 30 mm, and the rear central axis m1 is coplanar with the front central axis m and the two have an included angle α.

[0033] like Figure 5 to Figure 6 As shown, the gear seat 3 is installed in the rear accommodating portion 20, and the gear seat 3 is a hollow cylindrical structure. The first outer surface 30 of the gear seat 3 is in contact with the first accommodating surface 21; the second outer surface 31 of the gear seat 3 is consistent with the second accommodating surface 22, and the joint between the second outer surface 31 and the second accommodating surface 22 is fixed by a metal welding process.

[0034] The bottom of the tooth seat 3 has an open tooth withdrawal cavity 32, and the tooth withdrawal cavity 32 is connected to the rear accommodating portion 20 of the base 1. A through assembly hole 33 is provided in the middle of the tooth seat 3, and the assembly hole 33 has an assembly center axis m2, and the assembly center axis m2 coincides with the front center axis m. The tooth 4 is installed in the assembly hole 33 by an external expansion method. A carbide head 5 is welded to the top of the chisel 4 by a brazing process, which is the part that directly crushes the ground material or ore. There is a height H1 from the carbide head 5 to the mounting surface 16 of the base 1, and the size is 240mm. The height H1 is the working torque. A shorter working torque design can increase the cutting force of the basic base system, so that it can adapt to the crushing requirements of hard rock layers, help expand the working range of mining machinery, achieve multi-purpose use of one machine, save construction costs for customers, and improve work efficiency.

[0035] The basic base system provided in the present application is usually used in coal mining and mining occasions. Therefore, the chisel 4 needs to be replaced after its service life is reached. The disassembly tool will occupy the rear accommodation portion 20 and the tooth withdrawal cavity 32 along the X-axis direction to strike and eject the tooth 4.

[0036] like Figure 7 and Figure 8 As shown, the basic base system provided in the present application is arranged on the cylindrical drum 6 according to a set rule to form a cutting rotor. Specifically, two groups of basic base systems are arranged on the outer surface of the drum 6 in a cylindrical spiral line, and the two groups of basic base systems have a set distance in the axial direction of the drum. The ejection plate 7 is arranged on the outer surface of the drum 6 at intervals and is located between the two groups of basic base systems. In addition, each pair of basic base systems in the two groups of basic base systems is staggered in the circumferential direction of the cylinder. When working, the cutting rotor rotates rapidly around the circumferential direction of the drum (i.e., the arrow direction A), and the chisel 4 cuts and crushes the ground material or ore, so that the cut objects are concentrated from both sides to the middle. After being collected in the middle, they are transported to the transmission belt of the mechanical equipment by the discharge surface 70 of the ejection plate 7, and then transported to the material pile or transport truck.

[0037] As can be seen from the above, the basic base system provided by the present application adopts a lightweight and high structural strength design, and is equipped on a hard rock cutting rotor, which provides higher durability. The chisel can be easily disassembled, which improves the working comfort of the operator, reduces the risk of fatigue, and helps to achieve higher production. The ore particles are fine and uniform so that they can be directly used for further processing without additional crushing and screening, which is very suitable for truck and rail transportation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
