Description

Technical Field

[0001] This utility model relates to the field of aggregate processing technology, and in particular to an integrated aggregate crushing and mixing equipment. Background Technology

[0002] Permeable concrete is made by coating coarse aggregate with a thin layer of cement paste, which binds the aggregate together to form a honeycomb structure with evenly distributed pores. In the construction process, equipment is generally needed to crush the concrete aggregate.

[0003] For example, a Chinese patent discloses an integrated equipment for crushing and mixing recycled aggregates (publication number CN221999679U), which includes a mixing tank and a crushing box disposed above a base. The lower surface of the crushing box is fixedly connected to the upper surface of the mixing tank. A crushing mechanism is disposed inside the crushing box, and a conveying structure for conveying recycled aggregates is disposed outside the crushing box.

[0004] However, the aforementioned publicly available documents, through the combined use of a crushing mechanism, a conveying structure, and an integrated crushing and mixing mechanism, not only achieve the effect of integrated crushing and mixing but also effectively improve the crushing effect of materials, resulting in advantages such as strong practicality and good production efficiency. However, in use, the fixed installation of the filter screen can easily lead to untimely filtration and mesh clogging, thus hindering long-term use and widespread adoption. Therefore, those skilled in the art have provided an integrated aggregate crushing and mixing device to solve the problems mentioned in the background art. Utility Model Content

[0008] As a further technical solution of this utility model, the stirring assembly includes rotating plates fixedly sleeved on the front and rear ends of the outer peripheral sidewall of the rotating shaft two. Three sets of rolling rollers are rotatably installed between the two rotating plates. The outer peripheral sidewalls of the three sets of rolling rollers abut against the inner peripheral sidewall of the mixing box.

[0027] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5This utility model provides a technical solution for an integrated aggregate crushing and mixing equipment: It includes a support frame 1, with a screening component 2 inside the support frame 1. The screening component 2 includes a square frame 201 located inside the support frame 1. The inner bottom surface of the square frame 201 has several through-hole screens 202. A connecting plate 203 is bolted to the front outer wall of the square frame 201. Sliding rods 204 are symmetrically installed on the front outer wall of the connecting plate 203. A connecting plate 205 is bolted to the front outer wall of the support frame 1 (the threaded bolt connection allows for quick replacement of the return spring 211 when it loses elasticity due to metal fatigue). One end of each of the two sliding rods 204 is slidably sleeved on the connecting plate 205. Sliding blocks 206 are fixed to the left and right outer walls of the square frame 201. Support rods 206 are symmetrically fixed inside the support frame 1. 07. Two sliders 206 are respectively slidably sleeved on the outer walls of the two support rods 207 (the sliding of sliders 206 on support rods 207 can ensure the stability of the square frame 201 when moving laterally back and forth). A block 208 is fixed on the rear outer wall of the square frame 201. A rotating shaft 209 is rotatably installed inside the bracket 1. An eccentric wheel 210 is fixed on the outer wall of the rotating shaft 209. The outer wall of the eccentric wheel 210 abuts against the block 208. A return spring 211 is provided on the outside of the two sliders 204. The two ends of the two sets of return springs 211 are fixedly connected to the connecting plate 1 203 and the connecting plate 205 respectively. A drive motor 212 is fixedly installed on the left outer wall of the bracket 1. One end of the rotating shaft 209 extends to the left outer wall of the bracket 1 and is fixedly connected to the output end of the drive motor 212. In use, the drive motor 3 is controlled and started to drive the rotating shaft 3 209 to drive the eccentric wheel 210 to rotate. This causes the square frame 201 to move laterally along the outer wall of the two support rods 207 via the block 208. This allows the slide bar 204 to slide on the connecting plate 205 and compress the return spring 211 to cause elastic deformation, which in turn pushes the square frame 201 back to its original position. This cycle repeats to generate a vibration effect, which fully screens the aggregate in the square frame 201, avoiding untimely filtration and mesh blockage. At the same time, suitable aggregate falls into the collection box placed below through the screen holes 202, while larger aggregate is intercepted in the square frame 201 and prevented from spilling out by the frame wall. Afterwards, the staff can clean it up, thus improving its practicality.

[0029] A mixing box 101 is fixed to the top surface of the support 1. A discharge hood 501 is fixed and connected to the center of the bottom surface of the mixing box 101 (an electrically controlled valve installed on the discharge hood 501 facilitates its opening and closing, thereby facilitating the discharge of the crushed and mixed aggregate; the electrically controlled valve is existing technology, and its working principle and structural features will not be described or shown in this text). A crushing box 102 is fixed and connected to the top surface of the mixing box 101. A feeding hood 5 is fixed and connected to the top surface of the crushing box 102 (the feeding hood 5 facilitates the conveying of aggregate into the crushing box 102). Rotating shafts 103 are symmetrically rotatably mounted inside the crushing box 102. Crushing rollers 104 are fixedly sleeved on the outer walls of the two rotating shafts 103. Rotating shafts 105 are rotatably mounted inside the mixing box 101. Rotating shafts 105 and the two rotating shafts 103 are rotatably connected to each other through a linkage assembly 4. Next, the linkage component 4 includes a drive motor 401 fixed to the front outer wall of the mixing box 101. One end of the rotating shaft 105 extends to the front outer wall of the mixing box 101 and is fixedly connected to the output end of the drive motor 401, while the other end extends to the rear outer wall of the mixing box 101 and is fixed with a pulley 402. The two ends of the two rotating shafts 103 extend to the front and rear outer walls of the crushing box 102 respectively. In use, the drive motor 401 is controlled and started to drive the rotating shaft 105 to drive the pulley 402 to rotate. Under the rotational connection of the toothed belt 405, the pulley 404 drives one of the rotating shafts 103 to rotate. At the same time, under the meshing characteristics of the two gears 403, the other rotating shaft rotates synchronously, thereby driving the two crushing rollers 104 to rotate synchronously in opposite directions inside the crushing box 102 to crush the conveyed aggregate.

[0030] A stirring assembly 3 is provided on the outside of the rotating shaft 105. The stirring assembly 3 includes rotating plates 301 fixedly sleeved at the front and rear ends of the outer peripheral sidewall of the rotating shaft 105. Three sets of crushing rollers 302 are installed between the two rotating plates 301 and rotate together. The outer peripheral sidewall of the three sets of crushing rollers 302 abuts against the inner peripheral sidewall of the mixing box 101. A cylinder 303 is fixed at the center of the outer peripheral sidewall of the rotating shaft 105. A stirring blade 304 arranged in a circular array is fixed on the outer peripheral sidewall of the cylinder 303. When the crushed aggregate falls into the mixing box 101, the rotating shaft 105 synchronously drives the stirring blades 304 and the crushing rollers 302 to perform circular motion. This not only fully mixes the aggregate, but also further crushes the aggregate by rotating and abutting against the inner sidewall of the mixing box 101 through the crushing rollers 302, thereby improving the crushing effect of the aggregate.

[0031] The working principle of this utility model is as follows: When in use, the aggregate is first conveyed into the crushing box 102 along the feed cover 5, and then the drive motor 401 is started to drive the rotating shaft 105 and the rotating shaft 103 to rotate synchronously, so that the two crushing rollers 104 rotate synchronously in opposite directions to crush the aggregate.

[0032] Meanwhile, the crushed aggregate falls into the mixing box 101. The rotating shaft 105 synchronously drives the mixing blades 304 and the crushing roller 302 to perform circumferential motion. This not only fully mixes the aggregate, but also further crushes the aggregate by rotating and abutting against the inner wall of the mixing box 101 through the crushing roller 302, thus improving the crushing effect of the aggregate.

[0033] Meanwhile, the crushed and mixed aggregate is discharged into the square frame 201 through the discharge hood 501. The drive motor is started to rotate the eccentric wheel 210 by rotating the shaft 209. This causes the square frame 201 to move laterally along the outer wall of the two support rods 207, and the slide bar 204 slides on the connecting plate 205 to compress the reset spring 211 and cause it to deform elastically. This, in turn, pushes the square frame 201 back to reset. This cycle repeats to generate a vibration effect, which fully screens the aggregate in the square frame 201 and avoids untimely filtration and mesh blockage.

[0034] Finally, suitable aggregates fall through the sieve holes 202 into the collection box placed below, while larger aggregates are intercepted in the square box 201, after which the staff can clean them up.

[0035] It should be noted that all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
