Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to a screening crushing device. Background Technology

[0002] Material handling refers to the systematic process of transporting, storing, protecting and controlling materials. It covers the entire process from the procurement, transportation and storage of raw materials, to the handling in the production process, and then to the packaging, storage and distribution of finished products. In the field of material handling, screenable crushing devices are key equipment for realizing the integration of material crushing and grading.

[0003] Regarding the relevant technologies, the inventors believe that the following defects often exist: In the process of using existing screenable crushing devices, the replacement of the screen is relatively complicated, which leads to the screen not being cleaned in time. The screen is easily blocked by material residue, which not only reduces the screening efficiency and screening quality, but also aggravates the wear of the screen by the material and shortens its service life. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing screening crushing device has the disadvantage of complicated screen replacement during use, which leads to untimely cleaning, easy clogging, and reduced screening efficiency and quality. Therefore, we propose a screening crushing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a screenable crushing device, comprising a housing, a crushing device disposed inside the housing, a screen slidably connected inside the housing, a connecting shell fixed to one side of the housing, a support block disposed inside the connecting shell, a connecting rod fixed to one side of the support block, a top plate fixed to one end of the connecting rod, a sliding plate fixed to the top of the support block, a vertical rod fixed to the top of the sliding plate, a connecting hole for cooperating with the vertical rod being opened at the bottom of the screen, a pull plate slidably connected to the surface of the connecting rod, fixing blocks fixed to both ends of the pull plate, and four fixing holes for cooperating with the fixing blocks being opened on one side of the connecting shell.

[0006] Preferably, a first spring is slidably connected to the surface of the connecting rod, one end of the first spring is fixed to the top plate, and the other end of the first spring is fixed to the pull plate.

[0007] Preferably, guide blocks are fixed on both sides inside the connecting shell, and guide grooves that cooperate with the guide blocks are opened at both ends of the sliding plate.

[0008] Preferably, two second springs are fixed to the top of the sliding plate, the second springs are located on both sides of the vertical rod, and the other end of the second springs is fixed to the inside of the connecting shell.

[0009] Preferably, a guide block is fixed inside the box and is located above the crushing device; a guide plate is fixed inside the box and is located below the screen; and a discharge port is provided on one side of the box.

[0010] Preferably, an L-shaped plate is fixed to one side of the box body, and cylinders are fixed to both ends of one side of the L-shaped plate. The output end of the cylinder extends into the interior of the box body. A scraper is provided inside the box body. The bottom of the scraper abuts against the screen, and one side of the scraper is fixed to the output end of the cylinder.

[0011] Preferably, a groove is provided on the other side of the box body, and a collection box is fixed on the other side of the box body. The collection box is located on one side of the groove, and a pull-out box is slidably connected inside the collection box.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, by pulling the pull plate outward, the fixing block is moved away from the inside of the fixing hole. Then, the connecting rod is pulled to move the support block. The support block pulls the sliding plate away from the connecting shell, ensuring that the sliding plate smoothly pulls the vertical rod away from the inside of the connecting hole, thereby releasing the fixing of the screen and allowing the screen to be removed from the box. Through the above process, the maintenance of the screen is made more efficient. Timely cleaning of the screen can reduce the pore blockage caused by material residue, thereby improving screening efficiency and screening quality, reducing material wear on the screen, extending its service life, and adapting to different particle size screening needs.

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figures 1-5 As shown, this utility model provides a technical solution: a screenable crushing device, including a housing 1, a crushing device 2 disposed inside the housing 1, a screen 3 slidably connected inside the housing 1, a connecting shell 4 fixed to one side of the housing 1, a support block 5 disposed inside the connecting shell 4, a connecting rod 6 fixed to one side of the support block 5, a top plate 7 fixed to one end of the connecting rod 6, a sliding plate 8 fixed to the top of the support block 5, a vertical rod 9 fixed to the top of the sliding plate 8, a connecting hole 10 for use with the vertical rod 9 being opened at the bottom of the screen 3, and a pull plate 11 slidably connected to the surface of the connecting rod 6, both ends of the pull plate 11 being fixed. There is a fixing block 12, and a fixing hole 13 is opened on one side of the connecting shell 4 to cooperate with the fixing block 12. There are four fixing holes 13. A first spring 14 is slidably connected to the surface of the connecting rod 6. One end of the first spring 14 is fixed to the top plate 7, and the other end of the first spring 14 is fixed to the pull plate 11. Guide blocks 15 are fixed on both sides inside the connecting shell 4. Guide grooves 16 that cooperate with the guide blocks 15 are opened at both ends of the sliding plate 8. Two second springs 17 are fixed on the top of the sliding plate 8. The second springs 17 are located on both sides of the vertical rod 9, and the other end of the second springs 17 is fixed to the inside of the connecting shell 4. Specifically: The crushing device 2 crushes the material, which then falls onto the screen 3 for screening. After a period of use, residue tends to adhere to the pores of the screen 3, causing blockage. When cleaning and maintenance of the screen 3 is required, the pull plate 11 is pulled outward, and the tension of the first spring 14 quickly moves the fixing block 12 away from the inside of the fixing hole 13. Then, the connecting rod 6 is pulled to move the support block 5. The support block 5 pulls the sliding plate 8 away from the connecting shell 4. Simultaneously, the rebound force of the second spring 17, along with the structure of the guide block 15 and the second spring 17, effectively constrains the movement path of the sliding plate 8, preventing deviation and ensuring that the sliding plate 8 smoothly pulls the vertical rod 9 away from the connecting hole 10. Inside, the screen 3 is released from its fixation, allowing it to be removed from the housing 1. This process makes the maintenance of the screen 3 more efficient. Timely cleaning of the screen 3 reduces pore blockage caused by material residue, thereby improving screening efficiency and quality, reducing wear on the screen 3, and extending its service life. It also adapts to screening needs of different particle sizes. When the screen 3 needs to be installed, simply place it inside the connecting housing 4, then pull the pull plate 11 outward to move the fixing block 12 away from the fixing hole 13. Pull the connecting rod 6 to move the support block 5. The support block 5 pushes the sliding plate 8 towards the connecting housing 4. At this time, the second spring 17 is compressed, causing the vertical rod 9 to enter the connecting hole 10, thus fixing the screen 3. The operation is very convenient.

[0017] Reference Figure 1 and Figure 2 As shown in this embodiment: a guide block 18 is fixed inside the box 1, the guide block 18 is located above the crushing device 2, a guide plate 19 is fixed inside the box 1, the guide plate 19 is located below the screen 3, and a discharge port 20 is opened on one side of the box 1. Specifically: By setting the structure of the guide block 18, the material can be guided to fall accurately into the crushing device 2 for crushing, avoiding the material from falling outside the crushing device 2 and ensuring the normal operation of the crushing work. By setting the structure of the guide plate 19, the crushed and screened material will be discharged from the discharge port 20 along the guide plate 19. The guide plate 19 plays the role of guiding the material discharge direction, making the discharge smoother.

[0018] Reference Figure 2 and Figure 5As shown in this embodiment: an L-shaped plate 21 is fixed on one side of the box body 1, and cylinders 22 are fixed at both ends of one side of the L-shaped plate 21. The output end of the cylinders 22 extends into the interior of the box body 1. A scraper 23 is provided inside the box body 1. The bottom of the scraper 23 abuts against the screen 3, and one side of the scraper 23 is fixed to the output end of the cylinder 22. A groove 26 is provided on the other side of the box body 1, and a collection box 24 is fixed on the other side of the box body 1. The collection box 24 is located on one side of the groove 26, and a pull-out box 25 is slidably connected inside the collection box 24. Specifically: By setting up the structure of L-shaped plate 21, cylinder 22 and scraper 23, the cylinder 22 is activated, and its output end pushes the scraper 23 to move inside the box 1, thereby scraping off materials that do not conform to the aperture size from the screen 3, avoiding material accumulation and ensuring that the screen 3 is always unobstructed. By setting up a collection box 24 and a pull-out box 25, the material scraped off by the scraper 23 is collected. Then, the pull-out box 25 is pulled out from the collection box 24, and the material inside the pull-out box 25 is put back into the box 1 for crushing again using the crushing device 2.

[0019] Working Principle: The user crushes the material using the crushing device 2. The crushed material falls onto the screen 3 and is then screened. After a period of use, residue tends to adhere to the pores of the screen 3, causing blockage. When cleaning and maintenance of the screen 3 is required, the pull plate 11 is pulled outward, and the tension of the first spring 14 quickly moves the fixing block 12 away from the inside of the fixing hole 13. Then, the connecting rod 6 is pulled to move the support block 5. The support block 5 pulls the sliding plate 8 away from the connecting shell 4. Simultaneously, the rebound force of the second spring 17, along with the structure of the guide block 15 and the second spring 17, effectively constrains the movement path of the sliding plate 8, preventing deviation and ensuring that the sliding plate 8 smoothly pulls the vertical rod 9 away from the connecting hole 13. By removing the screen 3 from the housing 1, the screen 3 can be removed from the housing 1. This process makes the maintenance of the screen 3 more efficient. Timely cleaning of the screen 3 can reduce pore blockage caused by material residue, thereby improving screening efficiency and quality, reducing wear on the screen 3, and extending its service life. It can also adapt to screening needs of different particle sizes. When the screen 3 needs to be installed, simply place the screen 3 into the housing 4, then pull the pull plate 11 outward to move the fixing block 12 away from the fixing hole 13. Pull the connecting rod 6 to move the support block 5. The support block 5 pushes the sliding plate 8 towards the housing 4. At this time, the second spring 17 is compressed, which drives the vertical rod 9 into the housing 10, thereby fixing the screen 3. The operation is very convenient.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
