Description

Technical Field

[0001] The utility model belongs to the technical field of crushers, and particularly relates to a crushing device capable of screening crushed materials. Background Art

[0002] A crusher is a machine used to crush large materials into smaller particles. The main function of the crusher is to crush large raw materials into a size suitable for further processing. The working principle of the crusher is mainly based on the action of force. The material enters from the feed inlet of the crusher and is then crushed by the crushing components in the crushing chamber. The crushed material particles are discharged through the discharge outlet. Different types of crushers, such as jaw crushers, impact crushers, cone crushers, etc., have different specific crushing methods and working principles, but all achieve material crushing through the above methods.

[0003] Most existing crushers have certain limitations in use. After the material is initially crushed, it is very difficult to directly crush it into particles of the same size. Therefore, during use, it is necessary to perform a separate screening operation on the initially crushed material according to the use environment. After screening, the material is manually operated and put into the crusher again for crushing. This method not only increases the working intensity of the staff but also reduces the crushing efficiency.

[0004] Therefore, a crushing device capable of screening crushed materials is needed to solve the problems in the prior art that the crushed material needs to be screened separately later, and the screened material needs to be manually put into the crushing device for re-crushing. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a crushing device capable of screening crushed materials to solve the problems raised in the above background art.

[0008] It should be noted in the solution that the secondary crushing assembly includes a secondary box body. The secondary box body is fixedly connected to the outer wall of one side of the main box body corresponding to the first discharge port, and a through hole communicating with the first discharge port is penetrated and opened on the outer wall of one side of the secondary box body. A second feeding plate is fixedly connected to the inner wall of the secondary box body close to the first discharge port. Between the inner walls at both ends of the secondary box body, two second rotating shafts that are parallelly distributed are rotatably connected. On the outer surfaces of the two second rotating shafts, second crushing rollers are tightly sleeved. The outer wall of one end of one of the second rotating shafts penetrates through the outer wall of one end of the secondary box body, and a driving gear is tightly sleeved on the outer surface.

[0009] It is further worth noting that a guide plate arranged in an inclined shape is fixedly connected to the inner wall of the main box body, and a second discharge port is opened on the outer wall of one side of the main box body.

[0010] It is even further necessary to note that support legs are fixedly connected to the four corners of the bottom surface of the main box body, and two symmetrically distributed inclined blocks are fixedly connected to the inner wall of the bottom surface of the secondary box body.

[0011] As a preferred implementation manner, the guide block is triangular, and the two first gears are meshed with each other.

[0023] The crushing mechanism 6 includes two first rotating shafts 61 and a first motor 62 distributed in parallel. The outer walls on both sides of the two first rotating shafts 61 respectively rotate through the two mounting plates 5 and are rotatably connected to the inner walls on both sides of the main box body 1. The first motor 62 is fixedly connected to the outer wall of one side of the main box body 1. On the outer surfaces of both sides of the two first rotating shafts 61, first crushing rollers 63 are tightly sleeved.

The outer wall of one side of one of the first rotating shafts 61 rotates through the outer wall of one side of the main box body 1 and is coaxially fixedly connected to the output end of the first motor 62.

[0024] Further, as Figure 1 , Figure 3 and Figure 4 shown, specifically, the secondary crushing assembly 9 includes a secondary box body 91. The secondary box body 91 is fixedly connected to the outer wall of one side of the main box body 1 corresponding to the first discharge port 8, and a through hole communicating with the first discharge port 8 is provided through the outer wall of one side of the secondary box body 91. A second feeding plate 92 is fixedly connected to the inner wall of the secondary box body 91 close to the first discharge port 8. Two second rotating shafts 93 distributed in parallel are rotatably connected between the inner walls at both ends of the secondary box body 91. Second crushing rollers 94 are tightly sleeved on the outer surfaces of the two second rotating shafts 93. The outer wall of one end of one of the second rotating shafts 93 rotates through the outer wall of one end of the secondary box body 91 and a driving gear 95 is tightly sleeved on its outer surface. The outer wall of one end of the other second rotating shaft 93 rotates through the outer wall of one end of the secondary box body 91 and is coaxially fixedly connected to a driven gear 96 meshing with the driving gear 95. An installation frame 97 is fixedly connected to the outer wall of one end of the secondary box body 91. A second motor 98 is fixedly connected to the top surface of the installation frame 97. The output end of the second motor 98 is coaxially fixedly connected to the outer wall of one end of the second rotating shaft 93 on which the driving gear 95 is tightly sleeved. A discharge pipe 99 is fixedly communicated with the bottom surface of the secondary box body 91.

[0025] Further, as Figure 2 shown, specifically, a guiding plate 10 arranged in an inclined shape is fixedly connected to the inner wall of the main box body 1. A second discharge port 11 is provided on the outer wall of one side of the main box body 1.

[0026] Further, as Figure 1 and Figure 4As shown, it is worth specifically stating that support legs 12 are fixedly connected to the four corners of the bottom surface of the main box body 1, and two symmetrically distributed inclined blocks 13 are fixedly connected to the inner wall of the bottom surface of the auxiliary box body 91.

[0027] Furthermore, as Figure 2 shown, it is worth specifically stating that the material guiding block 4 is triangular, which divides the material into two parts for separate crushing to improve the crushing effect.

The first motor 62 drives one of the first rotating shafts 61 to rotate. Under the meshing action of the two first gears 64, the two first rotating shafts 61 rotate in opposite directions, thereby driving the first crushing roller 63 to rotate. The material guiding block 4 divides the input material into two parts for crushing, reducing the pressure during the operation of the crushing device and improving the crushing effect. The crushed material falls on the upper surface of the inclined sieve plate 7 for screening. The material meeting the crushing requirements passes through the sieve plate 7 and falls on the upper surface of the inclined material guiding plate 10, and finally is discharged through the second discharge port 11. There is no need for manual separate screening of the crushed material, effectively avoiding the problem that the crushed material needs to be separately screened subsequently.

[0030] The unqualified crushed material is intercepted by the sieve plate 7, enters the auxiliary box body 91 through the first discharge port 8, and is introduced between the two second crushing rollers 94 through the second feeding plate 92. At the same time, the second motor 98 rotates to drive the driving gear 95 and one of the second rotating shafts 93 to rotate. Under the meshing action, the driving gear 95 drives the driven gear 96 to rotate, and further drives the other second rotating shaft 93 to rotate. The two second rotating shafts 93 respectively drive the two second crushing rollers 94 to rotate in opposite directions to perform secondary crushing on the unqualified crushed material. The material after secondary crushing is discharged through the discharge pipe 99 under the guidance of the two inclined blocks 13, effectively avoiding the problem that the screened material needs to be manually put into the crushing device for re-crushing.

[0031] The first motor 62 and the second motor 98 can be purchased on the market. The first motor 62 and the second motor 98 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they are not repeated in the specification.
