In the prior art, the jaw crusher has strong crushing capacity, but the discharge hole is a strip-shaped hole formed by the cooperation of the fixed plate and the movable plate, and some flaky materials are easily discharged from the strip-shaped hole under the condition that the materials are not crushed or the crushing does not meet the particle size requirement in the crushing process, so that the partial materials are required to be crushed again, and even more times of crushing is carried out, so that the cost is high. The hammer crusher has the advantage of uniform discharge grain size, but causes that materials need to stay in the bin for a long time, the friction between the materials and a discharge net at the outlet of the bin is large, the failure rate of the discharge net is high, and the sliding cost is high.

In view of the above, the designer provides a multi-stage crushing device, which combines multi-stage crushers and has the advantages of strong crushing capacity, high yield, low failure rate and the like.

Referring to fig. 1-2, in this embodiment, the multi-stage crushing apparatus includes a first-stage crusher 100 and a second-stage crusher 200 connected to each other, where the types of the first-stage crusher 100 and the second-stage crusher 200 are different, a discharge port of the first-stage crusher 100 is connected to a feed port of the second-stage crusher 200, and the second-stage crusher 200 is used for crushing the material output from the first-stage crusher 100 and not meeting the particle size requirement.

In view of the above, the working principle of the multi-stage crushing device provided in this embodiment is as follows:

The multistage crushing device can be assembled on the swing arm of the excavator, namely the original bucket of the excavator is disassembled, and the multistage crushing device is assembled at the position of the excavator, which is originally used for assembling the bucket, so that the movable crushing operation is realized by combining the multistage crushing device with the excavator, and the movable crushing device is convenient to take, convenient to crush and high in efficiency. Automatic feeding can be achieved through the swing arms, namely the angle of the swing arms is adjusted, the feed inlet of the first-stage crusher 100 is used for aligning materials, and the materials are excavated. After the material loading is accomplished, start first order breaker 100 and second grade breaker 200, big particle diameter's material enters into first order breaker 100 earlier, first order breaker 100 breaks big particle diameter material, the discharge gate discharge of particle diameter reduction material from first order breaker 100 enters into the feed inlet of second grade breaker 200, because the material has accomplished a breakage, the particle diameter reduction of material, the operation load is little when second grade breaker 200 is broken, can be quick and effectual break the material once more, thereby satisfy required particle diameter requirement, the cooperation of two-stage breaker is used, it is high to have a crushing efficiency, the output is big and advantages such as fault rate are little.

It should be understood that, in both the first-stage crusher 100 and the second-stage crusher 200, there is no need to crush the material at the position, and the partial material is the material which itself meets the particle size requirement, that is, in the material to be crushed, most of the material has a particle size larger than the required particle size, but a small amount of the material can meet the requirement without crushing, so that the comprehensive operation cost is increased in the process of screening the material, and the like, the accumulated material is crushed together.

The following examples illustrate the detailed construction of the multi-stage crushing apparatus provided per se.

In this embodiment, the multi-stage crushing apparatus includes a housing 300, a first stage crusher 100, a second stage crusher 200, a screen 400, and a connection block 500.

The shell 300 is an elongated shell, the shell 300 has a first port and a second port along its length, the first port is a feed port 310 of the shell 300, which communicates with a feed port of the first stage crusher 100, and obviously, in other embodiments, the feed port 310 and the feed port may be one port. The second port may be a discharge port of the second stage crusher 200. The feed inlet 310 of the casing 300 is of a reducing structure, specifically, the caliber of the feed inlet 310 is gradually increased in the direction away from the discharge port of the first-stage crusher 100 from the feed inlet of the first-stage crusher 100, the amount of materials entering from the feed inlet 310 is larger, the material taking frequency can be reduced, the crushing time of the crusher for materials is longer under the same operation time limit, the yield can be increased, and the economic benefit is improved. The screen 400 is installed at the discharge port of the second-stage crusher 200, and can adjust the particle size of the discharged material. The connection base 500 is installed at the top of the casing 300, and the connection base 500 can be connected with a swing arm of an engineering machine such as a excavator.

Therefore, through the cooperation of the multistage crusher, the requirement of a user on the particle size of the material can be met while the high yield and the high efficiency are ensured.

In this embodiment, the first stage crusher 100 may alternatively be a jaw crusher. The jaw crusher comprises a movable jaw plate 110 and a fixed jaw plate 120 which are matched with each other, and the movable jaw plate 110 can move relative to the fixed jaw plate 120, so that the distance between the movable jaw plate and the fixed jaw plate is adjusted, and extrusion crushing of materials is realized. And a feed inlet and a discharge outlet are defined between the movable jaw plate 110 and the jaw plate 120, the opening of the feed inlet is larger than that of the discharge outlet, materials enter from the feed inlet, and materials meeting the particle size requirement after crushing are discharged from the discharge outlet.

In this embodiment, the second stage crusher 200 may be alternatively provided as a hammer crusher, a impact crusher, or the like. In the present embodiment, the second-stage crusher 200 is exemplified as a hammer crusher. The hammer crusher comprises a rotating shaft 210 and a pendulum 220, wherein the pendulum 220 is rotatably arranged on the rotating shaft 210, the rotating shaft 210 can drive the pendulum 220 to rotate, and the pendulum 220 is utilized to strike materials to realize crushing.
