Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a cone crusher for coarse aggregate production. Background Technology

[0002] A cone crusher is a type of mining machinery used for medium and fine crushing operations. It crushes materials such as ores and rocks through the squeezing and grinding action between a moving cone and a fixed cone. In construction, road engineering, and other fields, coarse aggregate is an indispensable raw material; as a key piece of equipment in the coarse aggregate production process, the performance of the cone crusher directly affects the quality of the coarse aggregate and the production efficiency.

[0003] Existing crushers often directly feed materials into the inlet, which may cause materials to frequently enter the crushing chamber through one side. This results in uneven material distribution within the crushing chamber and may also cause damage to the side that is in frequent contact. In addition, the crushed materials may vary in size, and some of the crushed materials may still not meet the size requirements, requiring separate screening later, which greatly reduces the crushing efficiency of coarse aggregates. Therefore, we need to propose a cone crusher for coarse aggregate production. Utility Model Content

[0004] The purpose of this utility model is to provide a cone crusher for coarse aggregate production. The coarse aggregate fed into the feed inlet is concentrated by the upper guide hopper and fed into the crusher body from the middle, thereby avoiding frequent contact between the coarse aggregate and one side, which would reduce the service life of the crushing chamber. The coarse aggregate is carried into the upper screening box by the lower guide hopper, and then screened through the screening screen to send the coarse aggregate that meets the requirements into the lower screening box and discharged through the lower discharge hopper. The coarse aggregate that does not meet the size requirements is discharged from the upper screening box through the upper discharge hopper, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cone crusher for coarse aggregate production, comprising a bottom plate, a crusher body, and a feed inlet at the top of the crusher body, wherein an upper guide hopper is provided on the upper surface of the feed inlet;

The screening screen is located inside the upper screening box, and the upper screening box is connected to the crusher body via a lower guide hopper.

[0008] Preferably, the material pushing module includes an upper scraper plate, a lower scraper plate, a locking block, and a driving structure. The upper scraper plate is slidably disposed inside the upper screening box, and the lower scraper plate is slidably disposed inside the lower screening box. Four sets of locking blocks are provided. Locking blocks are symmetrically disposed on both sides of the upper and lower scraper plates, and locking grooves corresponding to the locking blocks are opened on the inner sides of both the lower and upper screening boxes.

[0009] Preferably, the drive structure includes a servo motor, a lead screw, a driven gear, a toothed belt, and a driving gear. Two sets of lead screws are provided. The driven gear and the driving gear are respectively fixedly connected to the corresponding lead screws. The toothed belt is meshed and sleeved on the outer arc surface of the driven gear and the driving gear. The servo motor is connected to the driving gear via a connecting shaft.

[0010] Preferably, all four sets of locking blocks are configured as protrusions, and the locking block of the upper scraper near the driven gear is threaded onto the outer arc surface of a set of lead screws, and the locking block of the lower scraper near the driving gear is threaded onto the outer arc surface of another set of lead screws.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides: a cone crusher for coarse aggregate production, such as... Figure 1-4 As shown, the crusher includes a base plate 1, a crusher body 2, and a feed inlet 3 at the top of the crusher body 2. The crusher body 2 is supported on the upper surface of the base plate 1 by several sets of support legs 6, thereby ensuring the stability of the crusher body 2 during operation. An upper guide hopper 4 is provided on the upper surface of the feed inlet 3. The upper guide hopper 4 is provided above the feed inlet 3, so that the coarse aggregate fed into the feed inlet 3 is concentrated and fed into the crusher body 2 from the middle through the upper guide hopper 4. The upper guide hopper 4 is designed as a hollow inverted frustum shape, thereby avoiding frequent contact between the coarse aggregate and one side, which would reduce the service life of the crushing chamber.

[0024] Preferably, a screening assembly for screening coarse aggregate is provided on the upper surface of the base plate 1 and below the discharge port of the crusher body 2. The screening assembly includes a lower screening box 5, an upper screening box 7, a screening screen 14, and a pushing module. The lower screening box 5 is set on the upper surface of the base plate 1 by support legs. The upper screening box 7 is connected to the upper surface of the lower screening box 5. The screening screen 14 is set inside the upper screening box 7, and the upper screening box 7 is connected to the crusher body 2 by a lower guide hopper 11. The lower guide hopper 11 carries the coarse aggregate output from the upper screening box 7 into the upper screening box 7. Then, the coarse aggregate with the required size is screened into the lower screening box 5 through the screening screen 14 and discharged through the lower discharge hopper 8. The coarse aggregate that does not meet the size requirements is discharged from the upper screening box 7 through the upper discharge hopper 10. This makes it convenient to directly put the larger coarse aggregate back into the crusher body 2, thereby avoiding the need for separate screening later.

[0025] Specifically, the pushing module includes an upper scraper 15, a lower scraper 16, a locking block 20, and a driving structure. The upper scraper 15 is slidably disposed inside the upper screening box 7, and the lower scraper 16 is slidably disposed inside the lower screening box 5. Four sets of locking blocks 20 are provided, with locking blocks 20 symmetrically disposed on both sides of the upper scraper 15 and the lower scraper 16. The lower screening box 5 and the upper screening box 7 are both provided with locking grooves corresponding to the locking blocks 20. The upper scraper 15 is slidably disposed on the upper surface of the screening screen 14. After the crusher has finished working, the upper scraper 15 and the lower scraper 16 push the coarse aggregate inside the lower screening box 5 and the upper screening box 7 out, thereby avoiding the retention of coarse aggregate inside the lower screening box 5 and the upper screening box 7, which would affect the next use of the crusher.

[0026] Furthermore, the drive structure includes a servo motor 13, a lead screw 17, a driven gear 19, a toothed belt 21, and a drive gear 22. Two sets of lead screws 17 are provided. The driven gear 19 and the drive gear 22 are fixedly connected to the corresponding lead screws 17. The toothed belt 21 is meshed and sleeved on the outer arc surface of the driven gear 19 and the drive gear 22. The servo motor 13 is keyed to the drive gear 22 through a connecting shaft. When the servo motor 13 is started, it drives one set of lead screws 17 to rotate. The lead screw 17 drives the drive gear 22 to rotate. The drive gear 22 then drives the toothed belt 21 to rotate through meshing. The toothed belt 21 then drives the drive gear 22 to rotate through meshing, thereby driving the other set of lead screws 17 to rotate.

[0027] Furthermore, all four sets of locking blocks 20 are configured as protrusions, and the locking block 20 on the side of the upper scraper 15 near the driven gear 19 is threaded onto the outer arc surface of a set of lead screws 17, while the locking block 20 on the side of the lower scraper 16 near the driving gear 22 is threaded onto the outer arc surface of another set of lead screws 17. A support plate is fixedly installed on the side of the lower screening box 5, and the servo motor 13 is bolted to the upper surface of the support plate. A limit frame 18 is provided on the upper surface of the support plate, and the driven gear 19, toothed belt 21, and driving gear 22 are rotatably disposed inside the limit frame 18. The locking block 20 is a protrusion and moves along the locking groove, thereby ensuring that the two sets of lead screws 17 can thread-drive the two sets of locking blocks 20 to move, while preventing the locking block 20 from rotating with the lead screw 17. At the same time, the limit frame 18 is set to limit the driven gear 19, toothed belt 21, and driving gear 22 to prevent the driven gear 19, toothed belt 21, and driving gear 22 from deviating.

[0028] It is worth noting that the lower screening box 5 is connected to the upper discharge hopper 10 via a set of collection boxes 12 on its side, and the upper screening box 7 is connected to the lower discharge hopper 8 via another set of collection boxes 12 on its side. Two sets of conveyor platforms 9 are symmetrically arranged on the upper surface of the bottom plate 1. The two sets of conveyor platforms 9 are located below the lower discharge hopper 8 and the upper discharge hopper 10, respectively. The lower screening box 5, the upper screening box 7, the lower discharge hopper 8, the upper discharge hopper 10, and the collection boxes 12 are all inclined, with the side closer to the conveyor platform 9 being the lower side. This ensures that a large amount of coarse aggregate can smoothly enter the corresponding conveyor platform 9 from the lower discharge hopper 8 and the upper discharge hopper 10. The coarse aggregate with the required specifications is moved to the collection point by the conveyor platform 9 corresponding to the lower discharge hopper 8, and the larger coarse aggregate is moved to the coarse aggregate to be crushed by the conveyor platform 9 corresponding to the upper discharge hopper 10. This facilitates the further crushing of the larger coarse aggregate and avoids the need for separate screening later, thereby improving the efficiency of coarse aggregate crushing.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
