[0002] At present, stacker-reclaimer is the key equipment in the coal transportation system of thermal power plants. It is mainly used for the storage and excavation of materials. It has the advantages of large stacking and reclaiming capacity, small material field area, convenient operation, and easy automatic control. It can be used to dig and stack bulk materials such as coal, ore, sand and gravel, coke, etc. It is widely used in coal storage plants of thermal power plants, ore and coal raw material fields of large steel companies, large coking plants, large cement plants, large bulk cargo ports, light industry and chemical industry, large earthwork construction sites and other departments' storage plants.

The discharge conveying mechanism and the reclaiming conveying mechanism are arranged side by side in the body length direction. The material from the first material storage area can fall into the second material storage area after passing through the feed conveying mechanism, the first drop pipe and the discharge mechanism in sequence. The material from the second material storage area can fall into the first material storage area after passing through the reclaiming conveying mechanism, the second drop pipe and the return conveying mechanism in sequence.

[0004] However, there are still some shortcomings in its use: 1.

In the present invention, there will be friction between the coal and mineral materials and the spiral stirring shaft during the falling process. When the coal and mineral materials come into contact with the spiral stirring shaft, due to the rotation of the spiral stirring shaft, the materials will be subjected to a friction force in the opposite direction of rotation. This friction force will also slow down the falling speed of the materials because it also generates an additional resistance in the direction of the falling materials. Therefore, the falling speed of the coal and mineral materials can be slowed down, and the high-speed falling state can be avoided to cause a great impact force on the conveyor belt below the discharge pipe and the roller assembly below the conveyor belt.

DETAILED DESCRIPTION

[0019] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0020] See also Figure 1-15 The present invention is described in detail below with reference to the accompanying drawings and embodiments: like Figure 1-7As shown, a self-propelled rotary stacker includes a main transport truss 1, a mobile transport truss 3, a feeding mechanism 7, a throwing mechanism 5 and a conveyor belt 6. The mobile transport truss 3 is arranged below the main transport truss 1, corresponding to the position of the main transport truss 1. A mobile crawler vehicle 1 2 and a mobile crawler vehicle 2 21 are installed below the main transport truss 1. The mobile crawler vehicle 1 2 is arranged directly below the main transport truss 1, and the mobile crawler vehicle 2 21 is arranged at the left feed port position of the main transport truss 1. A gap is left between the two vehicles to allow the mobile transport truss 3 to pass through, and the main transport truss 1 can be driven to move by the mobile crawler vehicle 1 2 and the mobile crawler vehicle 2 21. like Figure 1-7 As shown, the mobile transport truss 3 is composed of multiple truss sections, and a transition crawler vehicle 4 is installed below the connection of each truss section. A spherical joint structure is provided at the upper end of the transition crawler vehicle 4, and the spherical joint structure is connected to the trusses at both ends to ensure that the transition crawler vehicle 4 below will not cause position changes to the mobile transport truss 3 when completing the turn, and to ensure that there is a good degree of freedom between the two trusses to avoid truss deformation caused by rigid connection or uneven ground. After the transition crawler vehicle 4 completes the turn, it changes from moving in the front-to-back direction to moving in the left-to-right direction. At this time, it can drive the mobile transport truss 3 to move to the left and protrude from the bottom of the main transport truss 1 to increase the distance of material transportation.

[0021] The above-mentioned mobile crawler vehicle 1 2, mobile crawler vehicle 2 21, transitional crawler vehicle 4 and spherical joint structure are all prior art and will not be described or drawn in detail here.

[0022] like Figure 1 As shown, the feeding mechanism 7 is installed at the left feeding end of the mobile transport truss 3 , and the throwing mechanism 5 is installed at the right discharging end of the main transport truss 1 .

[0023] like Figure 1-3 As shown, the main transport truss 1 and the mobile transport truss 3 are both equipped with roller assemblies, and the conveyor belt 6 is used in conjunction with the roller assemblies. The roller assemblies are used to support the conveyor belt 6, and a plurality of rollers are rotatably installed on the main transport truss 1 and the mobile transport truss 3. The rollers are slidably matched with the conveyor belt 6, and the conveyor belt 6 is driven to move by the rotation of the rollers; like Figure 1-3As shown, a working platform 12 is installed on the main transport truss 1, and a hydraulic tensioning cylinder 13 and a reducer mechanism 14 are installed on the working platform 12. The hydraulic tensioning cylinder 13 is connected to a roller on the main transport truss 1 to adjust the tension of the transport belt. The output end of the reducer mechanism 14 is connected to another roller on the main transport truss 1 to drive the roller so that the conveyor belt 6 moves above the roller assembly.

[0024] The above-mentioned roller assembly, hydraulic tensioning cylinder 13 and reducer mechanism 14 are all prior art and will not be drawn or described in detail here.

[0025] like Figure 1-3 As shown, an angle adjustment plate 11 is hingedly installed at the position of the left feed port of the main transport truss 1. The angle adjustment plate 11 is connected to the main transport truss 1 through a pulley and a connecting rope, and a roller assembly is also installed on the angle adjustment plate 11. The position of the angle adjustment plate 11 is fixed after the adjustment is completed, so as to reduce the height difference between the connection position of the conveyor belt 6 on the left side of the main transport truss 1 and the mobile transport truss 3, thereby improving the transportation effect of the materials.

[0026] like Figure 8-15 As shown, the feeding mechanism 7 includes a feeding pipe 71, a plurality of crushing components 72, a connecting pipe 73 and a speed reduction component 74 which are arranged in sequence from top to bottom; The crushing assembly 72 includes a support tube 1 721, a support tube 2 722 and a support tube 4 724. The upper end of the uppermost support tube 1 721 is fixedly connected to the lower end of the feed tube 71 by bolts. A connecting tube 3 7211 is fixedly sleeved on the outer side surface of the support tube 1 721. The lower end surface of the connecting tube 3 7211 is on the same horizontal plane as the lower end surface of the support tube 1 721. A plurality of supporting shafts 7213 are evenly fixedly arranged on the inner wall of the upper part of the connecting tube 3 7211 in an annular shape. The lower end surface of the supporting shaft 7213 is on the same horizontal plane as the lower end surface of the support tube 1 721. An annular support plate 7212 is fixedly provided on the lower end surface of the connecting tube three 7211, the inner circle diameter of the support plate 7212 is larger than the outer circle diameter of the supporting tube one 721, and the supporting plate 7212 is fixedly connected to the upper end of the supporting tube four 724 by bolts.

[0027] like Figure 8-11 As shown, the second support pipe 722 is composed of an upper cylindrical pipe and a lower frustum-shaped pipe; The upper end ring of the support tube 722 slides in the connecting tube 7211, and the support shaft 7213 penetrates the upper end ring of the support tube 722 and slides together. The compression spring 723 sleeved on the outer side of the support shaft 7213 is symmetrically fixedly arranged on the upper and lower end surfaces of the upper end ring of the support tube 722. The upper end of the upper compression spring 723 abuts against the upper inner wall of the connecting tube 7211, and the lower end of the lower compression spring 723 abuts against the upper surface of the support plate 7212. The outer ends of the compression springs 723 are fixedly provided with an annular rubber pad, which is located at the abutment. like Figure 8-11 As shown, the inner surface of the cylindrical pipe of the support tube 2 722 slides on the outer ring wall of the support tube 1 721, and the outer surface of the cylindrical pipe of the support tube 2 722 slides on the inner ring wall of the support tube 4 724.

[0028] like Figure 8-11 As shown, the tapers of the frustum-shaped pipes of the second support pipe 722 in each crushing assembly 72 are all different, wherein the taper refers to the ratio of the diameter difference between the upper and lower bottom circles to the height of the frustum, and the heights of the frustum-shaped pipes of the second support pipe 722 in each crushing assembly 72 are all the same, and the opening sizes of the upper bottoms are all the same, the lower bottom opening size of the uppermost frustum-shaped pipe is the largest, and the lower bottom opening size of the lowermost frustum-shaped pipe is the smallest; A crushing rod 7221 is fixedly arranged at the lower opening of each frustum-shaped pipe. The crushing rods 7221 on each frustum-shaped pipe are arranged vertically to each other, so as to perform preliminary crushing on the falling large materials.

[0029] Specifically, after the coal and mineral materials enter the upper feed pipe 71, they will pass through layers of support pipes 722 with different tapers. At this time, the scattered coal and mineral materials will be gradually gathered by the conical pipe, and the large coal particles therein can be crushed by a number of breaking rods 7221 during the gathering process, which can effectively reduce the coal particle size and meet the requirements of subsequent processing. In addition, due to its large particle size and heavy weight, large-particle coal will not only increase the load on the transportation equipment, but may also be damaged due to bumps and collisions during transportation, and even cause safety hazards.

[0030] Furthermore, when the falling coal and mineral materials pass through the layers of support tube 2 722, the coal and mineral materials in the outer circle will push the conical pipe of support tube 2 722. At this time, support tube 2 722 will fall, and the upper compression spring 723 will become a stretched state, and the lower compression spring 723 will become a compressed state, which can have a buffering effect on support tube 2 722 and increase the service life of support tube 2 722.

[0031] like Figure 12-15As shown, the reduction assembly 74 includes a reduction tube 741 and a symmetrically arranged support ring 76, the upper end of the reduction tube 741 is fixedly connected to the lower end of the connecting tube 1 73 by bolts, a connecting tube 2 75 is fixedly arranged on the outer surface of the lower end of the reduction tube 741, a discharge tube 751 is fixedly installed on the lower end of the connecting tube 2 75 by bolts, a gear 2 77 is rotatably arranged between the discharge tube 751 and the connecting tube 2 75, a driving motor 752 is fixedly arranged on the upper surface of the connecting tube 2 75, the output shaft of the driving motor 752 passes through the upper surface of the connecting tube 2 75 and rotates together, and a gear 1 753 is fixedly arranged on the protruding surface, the gear 1 753 is meshed with the gear 2 77, and the driving motor 752 drives the gear 1 753 to rotate, thereby driving the gear 2 77 to rotate.

[0032] like Figure 12-15 As shown, a plurality of spiral stirring shafts 761 are fixedly disposed on the opposite surfaces of the two support rings 76. The spiral stirring shafts 761 are evenly disposed on the surfaces of the support rings 76 in an annular shape. The conical stirring frame composed of the upper support ring 76 and the spiral stirring shaft 761 on its surface faces downward, and an annular connecting ring 763 is fixedly provided at the lower end of the spiral stirring shaft 761 to ensure the stability of the spiral stirring shaft 761 when rotating. The conical stirring frame composed of the support ring 76 below and the spiral stirring shaft 761 on its surface is directed upward, and a conical top head 762 is fixedly provided on the upper end of the spiral stirring shaft 761 to ensure the stability of the spiral stirring shaft 761 during rotation and to ensure that its upper end will not be bent and deformed by the coal and mineral materials falling from above.

[0033] like Figure 12-15 As shown, the two sets of spiral stirring shafts 761 intersect each other, and at the intersection, they can be connected and fixed by steel wires, or fixed by welding, so that the two conical stirring frames can be connected more tightly and the stirring effect of the falling coal and mineral materials can be enhanced.

[0034] like Figure 12-15 As shown, the inner wall surface of the lower support ring 76 is provided with a plurality of countersunk holes in a circular shape, and the inner wall surface of the gear 2 77 is provided with a plurality of bolt holes in a circular shape. The positions of the countersunk holes and the bolt holes correspond to those of the bolt holes, and the gear 2 77 and the support ring 76 can be fixed by bolts.

[0035] like Figure 12-15 As shown, the upper support ring 76 abuts against the lower end surface of the connecting tube 1 73 , and the upper support ring 76 can rotate freely relative to the lower end of the connecting tube 1 73 .

[0036] Specifically, after the coal and mineral materials pass through the layers of crushing components 72, they enter the deceleration tube 741 below through the connecting tube 1 73, and then contact the spiral stirring shaft 761 which is in a rotating state. At this time, the coal and mineral materials will not only be affected by the force of gravity during the falling process, but also by the force along the axis generated by the rotation of the spiral stirring shaft 761. This force will slow down the falling speed of the materials, because it generates a resistance in the direction opposite to the direction of gravity in the falling direction of the materials, and there will be friction between the coal and mineral materials and the spiral stirring shaft 761 during the falling process. When the coal and mineral materials contact the spiral stirring shaft 761, due to the rotation of the spiral stirring shaft 761, the materials will be subjected to a friction force in the opposite direction of rotation. This friction force will also slow down the falling speed of the materials, because it also generates an additional resistance in the direction of the falling direction of the materials. Therefore, the falling speed of the coal and mineral materials can be slowed down, avoiding the high-speed falling state from causing a great impact force on the conveyor belt 6 below the discharge pipe 751 and the roller assembly below the conveyor belt 6.

[0037] Furthermore, when the coal mineral material passes through the spiral stirring shaft 761, it will be further broken up by the spiral stirring shaft 761, so that the large volume of coal mineral material contained therein will be further processed, thereby improving the subsequent use effect of the coal mineral material.

[0038] like Figure 12-15 As shown, a number of connecting shafts 764 are evenly arranged in a ring shape between the two support rings 76. The connecting shafts 764 can be used to support the two support rings 76, and a square groove is opened on the outer surface of the connecting shaft 764. A square scraper 765 is arranged in the groove. After the scraper 765 is placed in the groove, the scraper 765 and the connecting shaft 764 can be fixed with bolts. A flexible rubber scraper strip is arranged on the outer side of the scraper 765. The scraper strip contacts the inner wall of the speed reducer tube 741 and will not cause damage to the inner wall of the speed reducer tube 741.

[0039] like Figure 12-15 As shown, a plurality of through holes equal in number to the connecting shaft 764 are opened in a circular shape on the end face of the lower support ring 76 to facilitate the passage of the connecting shaft 764, and a plurality of bolt holes equal in number to the connecting shaft 764 are opened in a circular shape on the lower end face of the upper support ring 76. The surfaces at the upper and lower ends of the connecting shaft 764 are threaded and can be matched with the bolt holes for connection. After the connecting shaft 764 is connected to the upper and lower support rings 76, a nut is used to finally tighten and fix the lower end of the connecting shaft 764.

[0040] Specifically, the connecting shaft 764 will rotate with the support ring 76. During the rotation of the support ring 76, the coal mineral material will be dispersed through the spiral stirring shaft 761. At the same time, a small amount of coal slag will splash onto the wall of the speed reducer tube 741. At this time, it can be cleaned by the flexible scraper strip on the outside of the scraper 765.

[0041] like Figure 5 As shown, the material throwing mechanism 5 includes a material throwing truss 1 51, a material throwing truss 2 52 and a discharging belt 55, a steering mechanism 54 is fixedly connected between the upper end of the material throwing truss 1 51 and the main transport truss 1, the lower right side of the material throwing truss 1 51 and the lower left side of the material throwing truss 2 52 are hinged, and a pitch cylinder 53 is hingedly provided on the right side of the upper end face of the material throwing truss 1 51, and the piston rod of the pitch cylinder 53 is hingedly connected to the left side of the upper end of the material throwing truss 2 52.

[0042] The above-mentioned steering mechanism 54 and pitch cylinder 53 are prior art and will not be described or drawn in detail here.

[0043] like Figure 5 As shown, a plurality of groups of roller assemblies are fixedly provided on the throwing truss 1 51 and the throwing truss 2 52, the discharging belt 55 is used in conjunction with the roller assembly, and rollers used in conjunction with the discharging belt 55 are rotatably installed on the throwing truss 1 51 and the throwing truss 2 52, a tensioning mechanism is provided on the left side of the throwing truss 1 51, and a driving unit is provided on the right side of the throwing truss 2 52, the tensioning mechanism is used in conjunction with the discharging belt 55, and the driving unit is used in conjunction with the rollers on the throwing truss 2 52.

[0044] The above-mentioned roller assembly, tensioning mechanism and driving unit are all prior art and will not be drawn or described in detail here.

[0045] Specifically, after the coal and mineral materials are transported by the main transport truss 1, they enter the discharge belt 55 on the right for transportation. At this time, the steering mechanism 54 can be used to drive the throwing truss 1 51 and the throwing truss 2 52 to rotate and adjust, and the pitch cylinder 53 can be used to adjust the angle of the throwing truss 2 52, so as to facilitate the unloading of the coal and mineral materials to the surroundings to form a material pile. Afterwards, the mobile crawler vehicle 1 2, the mobile crawler vehicle 2 21 and the transitional crawler vehicle 4 can be moved forward synchronously to drive the mobile transport truss 3, the active transport truss and the throwing mechanism 5 to move at the same time to continue unloading and stacking.

[0046] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0047] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system.
