detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Example: Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

Embodiment one

Given by Figures 1-7, the utility model comprises a crushing frame 1, a support function frame 2 positioned at the bottom of the crushing frame 1 and an auxiliary frame 3 positioned on one side of the support function frame 2, the bottom of the crushing frame 1 There is a screening port 4 communicating with the support function frame 2, and a number of evenly distributed barrier plates 5 are provided on both sides of the screening port 4, and a rotating shaft matched with the crushing frame 1 is provided inside the crushing frame 1. 12. A number of evenly distributed crushing rods 6 on the outer wall of the rotating shaft 12, a vibrating frame 7 is provided between the screening port 4 and the supporting functional frame 2, and a number of uniform Distributed vibrating sieve plate 8, the inside of the support function frame 2 is provided with a blanking chute 9, the inside of the blanking trough 9 is provided with a conveying mesh belt 10, and the auxiliary frame 3 is far away from the side of the support function frame 2 A collection frame 11 is provided on one side, and the conveying mesh belt 10 runs through the supporting function frame 2 and the auxiliary frame 3, and extends into the collection frame 11. One side of the crushing frame 1 is provided with the A crushing motor matched with the rotating shaft 12, a vibrating motor matched with the vibrating frame 7 and a conveying motor matched with the conveying mesh belt 10 are respectively provided on one side of the supporting function frame (2).

It is not difficult to see from the above design that the crushing frame 1 is a cylindrical structure with an opening at one end, and the opening is used as a feed inlet, and the coal mine is poured into the opening through a cover plate or any other suitable material inlet structural components installed at the opening. In the crushing frame 1, it is concentrated on the top of the screening port 4, and the middle position of the barrier plates 5 on both sides. Then the crushing motor and the vibration motor are started, and the rotating shaft 12 rotates at a high speed and drives the crushing rod 6 to rotate and impact the coal mine. Because of the size, hardness and quality of the coal mine, They are all different. When the crushing rod 6 rotates to crush the coal mine, the barrier plate 5 will block the coal mine from moving to the space on both sides of the crushing frame 1, and increase the distance from the crushing rod 6 to the crushed coal mine. At the same time, the gap in the middle of the barrier plate 5 will expand. The crushing effect of coal mines allows coal mines to be crushed to a size not larger than the gap between two barrier plates 5, and then enters the two sides of the crushing frame 1, and then breaks into smaller coal mines and passes through the vibrating screen plate 8 of the screening port 4 During the crushing period, the vibrating sieve plate 8 can not only screen coal mines of a certain size, because the vibrating frame 7 is driven by the high-frequency vibration of the vibrating motor, it can prevent the crushing rod 6 from jamming in the process of crushing coal mines, and increase or decrease It has the function of vibrating and crushing, and because it has multiple vibrating sieve plates 8, there are gaps installed. During the coal mine screening process, if there is a large coal mine stuck in the mesh or in the gap, high-frequency vibration can easily solve this problem. Such phenomena, and let the coal mine be further crushed to a reasonable size, and then the conveyor belt 10 completes the entire transportation process, and those that meet the size requirements are screened at the conveyor belt 10 and enter the blanking trough 9, and the larger ones are transported Collect or crush again in the collecting rack 11;

Embodiment two

As shown in Figures 4-7, on the basis of Embodiment 1, the position of the crushing rod 6 is located between the gaps between the two barrier plates 5, and the gaps between the two barrier plates 5 Not less than the width of the breaking rod 6;

Both sides of the barrier plate 5 and the inner wall of the crushing frame 1 are provided with crushing grooves;

The inside of the auxiliary frame 3 is provided with an auxiliary plate, and the auxiliary plate adjusts the distance from the top surface of the conveying mesh belt 10 through several threaded rods;

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

The number of the vibrating sieve plates 8 is not less than two, and the size of the sieve holes of each of the vibrating sieve plates 8 is arranged in descending order from top to bottom, and the vibrating sieve plates 8 and the vibrating frame 7 are fixedly connected by bolts .

It is not difficult to see from the above design that the coal mine will fall on the conveyor mesh belt 10 after passing through the vibrating screen plate 8, and the conveyor mesh belt 10 uses its metal structure and herringbone mesh to screen the screened coal mine again. , while rotating and transporting, during the process of rotating and transporting, the vibrating sieve plate 8 can still achieve the crushing effect by adjusting the distance between the vibrating sieve plate 8 and the conveying mesh belt 10, and utilizing the transmission power, herringbone holes and high-frequency vibration during the transmission process. Similarly, The auxiliary plate in the auxiliary frame 3 cooperates with the conveying mesh belt 10 at the same distance until the conveying mesh belt 10 completes the entire transportation process, and those that meet the volume size requirements are screened at the conveying mesh belt 10 and enter the blanking trough 9, which has a larger volume. The ones are transported to the collecting rack 11 for collection or crushing again.
