[0021] In summary, the present application has the following beneficial effects:

[0022] 1. In this invention, after the coal and mineral materials are transported by the main transport truss, they enter the discharge belt on the right side for conveying. At this time, the throwing truss one and the throwing truss two can be rotated and adjusted by the steering mechanism. The angle of the throwing truss two can be adjusted by the pitch cylinder, so as to facilitate the unloading of the coal and mineral materials to all sides to form a material pile. Then, the mobile tracked vehicle one, the mobile tracked vehicle two and the transition tracked vehicle can move forward synchronously, driving the mobile transport truss, the active transport truss and the throwing mechanism to move at the same time, which can effectively increase the transport range of the coal and mineral materials.

[0023] 2. In this invention, after the coal and mineral materials enter the upper feed pipe, they will pass through layers of support pipes with different tapers.

[0024] 3. In this invention, after the coal material passes through the layers of crushing components, it enters the deceleration tube below through the connecting pipe and then comes into contact with the rotating spiral stirring shaft. At this time, the coal material will not only be subject to the force of gravity during its fall, but also to the force along the axis generated by the rotation of the spiral stirring shaft. This force will slow down the falling speed of the material.

[0025] 4. In this invention, there is friction between the coal and the spiral mixing shaft during the falling process. When the coal and the spiral mixing shaft come into contact, due to the rotation of the spiral mixing shaft, the material will be subjected to a frictional force in the opposite direction of rotation. This frictional force will also slow down the falling speed of the material because it also generates an additional resistance in the direction of the falling material. Therefore, it can slow down the falling speed of the coal and the material and avoid the high-speed falling from causing great impact on the conveyor belt below the discharge pipe and the idler assembly below the conveyor belt.

[0059] A crushing rod 7221 is fixedly arranged at the lower end opening of each conical pipe, and the crushing rods 7221 on each conical pipe are vertically arranged, so as to preliminarily crush the large material falling down.

[0060] Specifically, after the coal mine material enters the upper feed pipe 71, the dispersed coal mine material will be gradually gathered by the conical pipes with different tapers, and the large coal mine particles can be crushed by the crushing rods 7221 in the gathering process, so as to effectively reduce the particle size of the coal mine and meet the requirements of subsequent processing, and the large coal mine particles will not only increase the load of the transportation equipment, but also may be damaged due to bumping and collision in the transportation process, and even cause safety hazards. ​​​

[0061] Further, when the falling coal mine materials pass through the layer-by-layer support pipe two 722, the coal mine materials at the outer ring will push the conical pipe of the support pipe two 722, at this time, the support pipe two 722 will fall, the upper compression spring 723 becomes a stretching state, and the lower compression spring 723 becomes a compression state, which can buffer the support pipe two 722 and improve the service life of the support pipe two 722.

[0062] As shown in Figures 12-15 The speed reduction assembly 74 includes a speed reduction pipe 741 and symmetrically arranged support rings 76, the upper end of the speed reduction pipe 741 is fixedly connected with the lower end of the connecting pipe one 73 through bolts, the lower end outer surface of the speed reduction pipe 741 is fixedly provided with a connecting pipe two 75, the lower end of the connecting pipe two 75 is fixedly installed with a discharge pipe 751 through bolts, the discharge pipe 751 and the connecting pipe two 75 are rotationally provided with a gear two 77, the upper surface of the connecting pipe two 75 is fixedly provided with a driving motor 752, the output shaft of the driving motor 752 penetrates the upper surface of the connecting pipe two 75 and is rotationally matched, and the gear one 753 is fixedly provided on the surface beyond the output shaft and is engaged with the gear two 77, the gear one 753 is driven to rotate by the driving motor 752, and in turn drives the gear two 77 to rotate.

[0063] As shown in Figures 12-15 The opposite surfaces of the two support rings 76 are fixedly provided with a plurality of spiral stirring shafts 761, the spiral stirring shafts 761 are annularly and uniformly arranged on the surfaces of the support rings 76,

[0064] The conical stirring frame composed of the upper support ring 76 and the spiral stirring shafts 761 on the surface thereof is directed downward, and the annular connecting ring 763 is fixedly arranged at the lower end of the spiral stirring shaft 761 at this place to ensure the stability of the rotation of the spiral stirring shaft 761 at this place,

[0065] The conical stirring frame composed of the lower support ring 76 and the spiral stirring shafts 761 on the surface thereof is directed upward, and the conical top head 762 is fixedly arranged at the upper end of the spiral stirring shaft 761 at this place to ensure the stability of the rotation of the spiral stirring shaft 761 at this place and ensure that the upper end thereof will not be bent and deformed by the falling coal mine materials above.

[0066] As shown in Figures 12-15 The two groups of spiral stirring shafts 761 intersect with each other, and at the intersection points, can be fixedly connected by steel wires or fixedly connected by welding, so that the two conical stirring frames are more closely connected and the stirring effect on the falling coal mine materials is enhanced.

[0067] As shown in Figures 12-15As shown, the inner wall of the lower support ring 76 is annularly provided with a plurality of countersunk holes, and the inner wall of the gear two 77 is annularly provided with a plurality of bolt holes. The positions of the countersunk holes and the bolt holes correspond to each other, so that the gear two 77 and the support ring 76 can be fixed by bolts.

[0069] Specifically, after the coal materials pass through the layer-by-layer crushing assembly 72, the coal materials enter the lower speed-reducing pipe 741 through the connecting pipe one 73, and then contact the spiral stirring shaft 761 which is in a rotating state. At this time, the coal materials not only receive the force of gravity during falling, but also receive the force along the axial direction generated by the rotation of the spiral stirring shaft 761. This force slows down the falling speed of the materials, because it generates an additional resistance in the direction opposite to the direction of gravity. In addition, the coal materials generate a friction force with the spiral stirring shaft 761 during falling. When the coal materials contact the spiral stirring shaft 761, the materials receive a friction force opposite to the direction of rotation due to the rotation of the spiral stirring shaft 761. This friction force also slows down the falling speed of the materials, because it generates an additional resistance in the direction of falling. Therefore, the falling speed of the coal materials can be slowed down, so as to avoid the great impact force on the conveying belt 6 below the discharging pipe 751 and the roller assembly below the conveying belt 6.

[0070] Further, the coal materials are further dispersed by the spiral stirring shaft 761 when passing through the spiral stirring shaft 761, so that the large-volume coal materials contained in the coal materials are further processed, thereby improving the use effect of the coal materials.

A square scraper 765 is arranged in the groove, and the scraper 765 is fixed to the connecting shaft 764 by bolts. A flexible rubber scraper is arranged on the outer side surface of the scraper 765, which contacts the inner wall of the speed-reducing pipe 741 and does not damage the inner wall of the speed-reducing pipe 741.

[0072] As shown in the drawings, Figures 12-15As shown, the end face of the lower support ring 76 is annularly provided with a plurality of through holes same in number with the connecting shafts 764, facilitating the penetrating of the connecting shafts 764, and the lower end face of the upper support ring 76 is annularly provided with a plurality of bolt holes same in number with the connecting shafts 764, and the upper and lower ends of the connecting shafts 764 are provided with threads, which can be connected with the bolt holes, and after the connecting shafts 764 are connected with the upper and lower support rings 76, nuts are finally used to finally tighten and fix the lower ends of the connecting shafts 764.

[0073] Specifically, the connecting shafts 764 rotate with the support rings 76, and in the rotating process of the support rings 76, the coal mine materials are scattered by the spiral stirring shaft 761, and a small part of the coal cinder splashes on the wall of the speed reduction pipe 741, which can be cleaned by the flexible scraper strips outside the scraper 765.

[0074] As shown in the figure, Figure 5 The material throwing mechanism 5 includes a material throwing truss one 51, a material throwing truss two 52 and a discharging belt 55, the upper end of the material throwing truss one 51 is fixedly connected with a steering mechanism 54 between the main body conveying truss 1, the lower right side of the material throwing truss one 51 and the lower left side of the material throwing truss two 52 are hingedly matched, and the upper end of the material throwing truss one 51 is hingedly provided with a pitch cylinder 53 on the right side, and the piston rod of the pitch cylinder 53 is hingedly connected with the upper end of the material throwing truss two 52.

[0075] The above-mentioned steering mechanism 54 and pitch cylinder 53 are prior art, and will not be described and drawn in detail.

[0076] As shown in the figure, Figure 5 The material throwing truss one 51 and the material throwing truss two 52 are both fixedly provided with a plurality of groups of roller assemblies, the discharging belt 55 is used in cooperation with the roller assemblies, and the roller assemblies are rotatably installed on the material throwing truss one 51 and the material throwing truss two 52 and used in cooperation with the discharging belt 55, a tensioning mechanism is arranged on the left side of the material throwing truss one 51, and a driving unit is arranged on the right side of the material throwing truss two 52, the tensioning mechanism is used in cooperation with the discharging belt 55, and the driving unit is used in cooperation with the roller on the material throwing truss two 52.
