[0002] Crusher machinery is used for crushing materials and is widely used in many sectors such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. It features a large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and economical operating costs, and is commonly used in various industries for pulverizing materials.
[0003] Common crushers simply transport the crushed material to the outside environment when crushing it, without being able to screen or classify the crushed material according to its particle size. When workers need to use the crushed material, they still need to screen it again. Common crushers have a relatively simple function: they can only crush materials and cannot screen or classify the crushed material at the same time. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crusher with screening function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A crusher with screening function includes a machine body. Mounting shafts are rotatably mounted at both ends of the inner top of the machine body. Rolling rollers are mounted on the outer walls of both mounting shafts. A screening shell matching the two rolling rollers is mounted on the inner top of the machine body. The two rolling rollers are located at the inner ends of the screening shell. A bottom plate is mounted on the inner wall of the bottom end of the screening shell. Several screening holes are provided on the inner wall of the screening shell and the top of the bottom plate. A lifting sleeve is slidably mounted on the outer wall of the screening shell. Several crushing teeth are mounted on the outer walls of both rolling rollers.
[0007] Preferably, guide grooves are provided at both ends of the inner walls on both sides of the machine body. An electric slider is slidably installed inside the guide groove. A support rod is installed at the end of the electric slider away from the inner wall of the guide groove. The end of the support rod away from the electric slider is installed on the outer wall of the lifting sleeve. The inner wall of the lifting sleeve abuts against the outer wall of the screening shell.
[0008] Preferably, the bottom end of the mounting shaft is rotatably mounted on the top of the base plate, and a mounting sleeve is installed on the outer wall of the bottom end of the mounting shaft. Scrapers are installed on the outer walls of both ends of the mounting sleeve, and the bottom of the scrapers abuts against the top of the base plate.
[0009] Preferably, a fixing plate is installed on both sides of the bottom of the base plate, and an mounting plate is installed on the top end of the fixing plate away from the base plate. The side of the mounting plate abuts against the outer wall of the screening shell, and a mounting hole is opened on the top side of the mounting plate.
[0010] Preferably, the inner bottom of the machine body is provided with guide grooves at both ends, and a discharge port is provided on the inner wall of the end of the guide groove away from the bottom plate, and the end of the discharge port away from the guide groove passes through the machine body.
[0011] Preferably, the top two sides of the screening shell are provided with fixing grooves, and the two sides of the machine body are provided with fixing holes. A feeding plate is installed inside the fixing hole.

[0012] Preferably, the top end of the mounting shaft passes through the machine body and is equipped with a motor, while the bottom end of the motor is mounted on the top of the machine body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, after the material is crushed, it can move downwards inside the screening shell by its own weight. The crushing roller can push the moving material towards the inner wall of the screening shell. When the crushed material moves downwards, the smaller particles fall through the screening holes on the inner wall of the screening shell to the bottom of the machine, while the larger particles fall to the top of the bottom plate and are located between the two crushing rollers. The space inside the screening shell between the bottom plate and the crushing roller can store the larger particles, making it convenient for workers to classify and screen the material according to the size of the crushed particles.
[0015] 2. In this utility model, during use, the operator can use the electric slider and support rod to move the lifting sleeve up and down on the outer wall of the screening shell according to the usage situation. This allows the lifting sleeve to clean the outer wall of the screening shell in real time, preventing the screening holes from becoming clogged when the crushed material is screened. This facilitates better screening of the material by the screening shell and screening holes. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-5 A crusher with screening function includes a body 1. Mounting shafts 7 are rotatably mounted at both ends of the inner top of the body 1. Rollers 9 are mounted on the outer walls of the two mounting shafts 7. Screening shells 8 that match the two rollers 9 are mounted on the inner top of the body 1. The two rollers 9 are located at the inner ends of the screening shell 8. A bottom plate 10 is mounted on the inner wall of the bottom end of the screening shell 8. Several screening holes 15 are opened on the inner wall of the screening shell 8 and the top of the bottom plate 10. A lifting sleeve 11 is slidably mounted on the outer wall of the screening shell 8. Several crushing teeth 19 are mounted on the outer walls of the two rollers 9.
[0024] As a technical optimization of this utility model, guide grooves 12 are provided at both ends of the inner walls on both sides of the body 1. An electric slider 13 is slidably installed inside the guide groove 12. A support rod 14 is installed at the end of the electric slider 13 away from the inner wall of the guide groove 12. The end of the support rod 14 away from the electric slider 13 is installed on the outer wall of the lifting sleeve 11. The inner wall of the lifting sleeve 11 abuts against the outer wall of the screening shell 8. When in use, the lifting sleeve 11 can clean the outer wall of the screening shell 8 to prevent the screening holes 15 on the outer wall of the screening shell 8 from becoming blocked.
[0025] As a technical optimization of this utility model, the bottom end of the mounting shaft 7 is rotatably mounted on the top of the base plate 10. An mounting sleeve 20 is installed on the outer wall of the bottom end of the mounting shaft 7. Scrapers 21 are installed on the outer walls of both ends of the mounting sleeve 20. The bottom of the scraper 21 abuts against the top of the base plate 10. The scraper 21 can scrape the material on the top of the base plate 10, so that the fine particles of the crushed material fall into the inner bottom of the machine body 1 along with the screening holes 15 on the base plate 10.
[0026] As a technical optimization of this utility model, a fixing plate 16 is installed on both sides of the bottom of the base plate 10. An mounting plate 17 is installed at the top end of the fixing plate 16 away from the base plate 10. The side of the mounting plate 17 abuts against the outer wall of the screening shell 8. An mounting hole 22 is opened on the top side of the mounting plate 17. The operator can fix the mounting plate 17 and the screening shell 8 with bolts.
[0027] As a technical optimization of this utility model, both ends of the inner bottom of the machine body 1 are provided with guide grooves 6. The inner wall of the guide groove 6 away from the bottom plate 10 is provided with a discharge port 5. The end of the discharge port 5 away from the guide groove 6 passes through the machine body 1. When the crushed material falls to the inner top of the machine body 1, the material can be discharged to the outside through the guide groove 6 and the discharge port 5.
[0028] As a technical optimization of this utility model, the top two sides of the screening shell 8 are provided with fixing grooves 18, and the two sides of the machine body 1 are provided with fixing holes 2. The inside of the fixing holes 2 is equipped with a feeding plate 3. One end of the feeding plate 3 is installed at the bottom of the fixing groove 18, and the other end of the feeding plate 3 is located on the side of the machine body 1. The operator can push the material to be crushed into the inside of the screening shell 8 through the feeding plate 3, and crush the material by the cooperation of the crushing roller 9 and the inner wall of the screening shell 8.
[0029] As a technical optimization of this utility model, the top end of the mounting shaft 7 passes through the machine body 1 and is equipped with a motor 4. The bottom end of the motor 4 is installed on the top of the machine body 1. The motor 4 can drive the rolling roller 9 and the scraper 21 to rotate through the mounting shaft 7.
[0030] In use, the operator places the material to be crushed inside the two feed plates 3 and pushes the feed plates 3 inwards towards the inside of the machine body 1 until the material enters the screening shell 8. Two motors 4 drive two grinding rollers 9 located inside the screening shell 8 via two mounting shafts 7. During use, a certain gap is maintained between the outer wall of the grinding rollers 9 and the inner wall of the screening shell 8 to facilitate the storage and crushing of the material entering the screening shell 8. The material to be crushed inside the screening shell 8 is located between the grinding rollers 9 and the screening shell 8. When the grinding rollers 9 rotate, they move the material between their outer wall and the inner wall of the screening shell 8. The rotating grinding rollers 9 compress the material and cooperate with the inner wall of the screening shell 8 to crush the material between the inner wall of the screening shell 8 and the grinding rollers 9.
[0031] During use, several crushing teeth 19 are installed on the outer wall of the crushing roller 9, which increases the friction of the outer wall of the crushing roller 9, making it easier for the crushing roller 9 to move the material. The two crushing rollers 9 rotate in opposite directions. When the crushing roller 9 rotates, it can move the material to one side between the two crushing rollers 9, and push the material towards the position between the two crushing rollers 9. The two crushing rollers 9 can then squeeze and crush the material on their opposite sides.
[0032] After the material is crushed, it can move downwards inside the screening shell 8 under its own weight. The crushing roller 9 can push the moving material against the inner wall of the screening shell 8, so that the smaller particles fall through the screening holes 15 on the inner wall of the screening shell 8 to the bottom of the machine body 1 as the crushed material moves downwards. As the larger particles move downwards inside the screening shell 8, the crushing roller 9 and the inner wall of the screening shell 8 work together to continue to crush the material. When the larger particles are still large in volume after crushing, they can fall to the top of the bottom plate 10 and be located between the two crushing rollers 9. The space inside the screening shell 8 between the bottom plate 10 and the crushing rollers 9 can store the larger particles, making it convenient for workers to classify and screen the material according to the particle size after crushing.
[0033] During use, the operator can use the electric slider 13 and support rod 14 to move the lifting sleeve 11 up and down on the outer wall of the screening shell 8, so that the lifting sleeve 11 can clean the outer wall of the screening shell 8 in real time, preventing the screening holes 15 from becoming clogged when the crushed material is screened, and making it easier for the screening shell 8 and the screening holes 15 to screen the material better.
[0034] When the mounting shaft 7 drives the crushing roller 9 to rotate, it can also drive the scraper 21 to rotate through the mounting sleeve 20. The scraper 21 pushes the material on the top of the bottom plate 10, causing smaller particles remaining on the top of the bottom plate 10 to fall through the screening holes 15 on the bottom plate 10 to the bottom of the machine body 1, while larger particles remain stored on the top of the bottom plate 10. The material that falls to the bottom of the machine body 1 can slide along the inner wall of the guide channel 6 towards the discharge port 5 and be discharged to the outside through the discharge port 5, making it convenient for workers to retrieve the crushed material.
[0035] After the material is crushed, the staff can disassemble the base plate 10 through the mounting plate 17 and the fixing plate 16, so that the larger particles stored on the top of the base plate 10 can be discharged to the outside through the guide channel 6 and the discharge port 5. The staff can collect the remaining larger particles after crushing.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
