Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Given by fig. 1-7, the utility model discloses a broken frame 1, be located the support function frame 2 of broken frame 1 bottom with be located support function frame 2 one side auxiliary frame 3, broken frame 1's bottom seted up with support function frame 2 is linked together sieve mouth 4, sieve mouth 4's both sides are equipped with a plurality of evenly distributed's baffler 5, broken frame 1's inside is equipped with rather than matched with pivot 12, a plurality of evenly distributed's of outer wall crushing pole 6 of pivot 12, sieve mouth 4 with be equipped with vibration frame 7 between the support function frame 2, two liang be equipped with a plurality of evenly distributed's vibration sieve board 8 between the vibration frame 7, support function frame 2's inside is equipped with blanking groove 9, blanking groove 9's inside is equipped with conveying mesh belt 10, auxiliary frame 3 keeps away from one side of support function frame 2 is equipped with collection frame 11, conveying mesh belt 10 runs through support function frame 2 with auxiliary frame 3 to extend to in collection frame 11, one side of broken frame 1 be equipped with pivot 12 matched with crushing motor, support function frame (2) is equipped with conveying mesh belt 10 and conveying motor matched with respectively.

As can be seen from the above design, the crushing frame 1 is a cylindrical structure with an opening at one end, the opening is used as a feeding hole, the coal mine is poured into the crushing frame 1 at the opening through a cover plate or any other matched blanking inlet structure component, and is concentrated above the screening opening 4, the middle position of the baffle plates 5 at the two sides is arranged, then the crushing motor and the vibrating motor are started, the rotating shaft 12 rotates at high speed and drives the crushing rod 6 to rotate to impact the coal mine, because the size, hardness and quality of the coal mine are different, when the crushing rod 6 rotates to crush the coal mine, the blocking plates 5 can block the coal mine from moving to the two side spaces inside the crushing frame 1, the distance from the crushing rod 6 to the crushed coal mine is increased, meanwhile, the gap in the middle of the blocking plates 5 expands the crushing effect of the coal mine, the coal mine can be crushed to the size not larger than the gap between every two blocking plates 5, then enters the two sides of the crushing frame 1, is crushed into a coal mine with smaller volume again and falls down through a vibrating sieve plate 8 of a sieving port 4, during crushing, the vibrating screen plate 8 can not only screen a coal mine with a certain submitted size, but also prevent the crushing rod 6 from blocking the shell in the process of crushing the coal mine due to the high-frequency vibration of the vibrating frame 7 driven by the vibrating motor, and the vibration crushing function is increased and decreased, and because the plurality of vibration sieve plates 8 are arranged and the gaps are arranged, the coal mine can be crushed in the sieving process, if a coal mine with larger volume blocks meshes or is positioned in gaps, the phenomenon can be easily solved by high-frequency vibration, further crushing the coal mine to a reasonable size, then completing the whole transportation process by the conveying mesh belt 10, screening the coal mine meeting the size requirement of the size at the conveying mesh belt 10 and entering a blanking chute 9, and conveying the coal mine with larger size to a collection frame 11 for collection or re-crushing;

example two

As shown in fig. 4 to 7, on the basis of the first embodiment, the position of the crushing rod 6 is located between the gap between every two barrier plates 5, and the gap between every two barrier plates 5 is not smaller than the width of the crushing rod 6;

crushing grooves are formed in the two sides of the blocking plate 5 and the inner wall of the crushing frame 1;

an auxiliary plate is arranged inside the auxiliary frame 3, and the distance between the auxiliary plate and the top surface of the conveying mesh belt 10 is adjusted through a plurality of threaded rods;

the conveying mesh belt 10 is a stainless steel conveying mesh belt, and meshes of the conveying mesh belt 10 are herringbone meshes;

two, every are no less than to the quantity of vibration sieve 8 the sieve mesh size of vibration sieve 8 from top to bottom is progressively reduced to be arranged in proper order, vibration sieve 8 with vibration frame 7 passes through bolt fixed connection.

It is not difficult to see from above-mentioned design, the colliery can fall on conveying mesh belt 10 after vibrating screen plate 8, conveying mesh belt 10 utilizes its metallic structure and chevron shape mesh, the colliery after the screening is sieved again, rotate the transportation simultaneously, in the in-process of rotating the transportation, vibrating screen plate 8 still can be through adjusting the distance with conveying mesh belt 10, utilize transmission power in the data send process, chevron shape hole and high-frequency vibration reach crushing effect, and similarly, the accessory plate in auxiliary frame 3 keeps away from with conveying mesh belt 10 cooperation with the same, until conveying mesh belt 10 accomplishes whole transportation flow, accord with the volume size requirement sieve entering blanking groove 9 in conveying mesh belt 10 department, the great then of volume is carried and is collected or is broken once more in collecting frame 11.
