Description

Technical Field

[0001] This utility model relates to the field of concrete crushing technology, specifically to a concrete block crushing structure. Background Technology

[0002] In construction projects such as building demolition, road renovation, and mining, a large number of waste concrete blocks are generated. If these blocks are not properly disposed of, they not only occupy valuable land resources but also pollute the surrounding soil, water sources, and other ecological environments due to long-term stockpiling. Therefore, crushing and reusing waste concrete blocks to transform them into recycled aggregates and other materials that can be reused in construction projects has become a key measure for the industry to achieve resource recycling and reduce environmental pressure. In previous research and experiments on concrete block crushing, the traditional method has often used excavators to crush the concrete blocks one by one. However, this method has many significant drawbacks, which seriously restrict the development and progress of related experiments. From an efficiency perspective, crushing concrete blocks one by one with excavators is extremely inefficient. Since an excavator can only process one concrete block at a time, dealing with a large number of blocks requires a lot of time and manpower, resulting in a lengthy crushing process that cannot meet the needs of large-scale projects for efficient disposal of waste concrete blocks, greatly limiting the overall progress of the project. In terms of crushing effect, this method is difficult to guarantee the uniformity and precision of the crushed particle size. When excavators crush concrete blocks, the force and manner of action are difficult to control precisely, resulting in inconsistent particle sizes and quality of the crushed concrete blocks. This not only increases the difficulty and cost of subsequent screening and reprocessing, but also makes it difficult to meet the strict requirements of different projects for the particle size of recycled aggregates, thus affecting the quality and applicability of recycled materials.

[0003] Therefore, the inventor of this utility model proposes a concrete block crushing structure to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete block crushing structure to solve the technical problem that the existing excavators crush concrete blocks one by one, which is inefficient and cannot meet the needs of large-scale projects for efficient processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A concrete block crushing structure includes a frame, a crushing assembly, and a driving assembly, wherein the crushing assembly and the driving assembly are fixedly mounted on the frame. The crushing assembly includes a crushing box, a movable jaw, and at least one crushing roller disposed within the crushing box. The movable jaw is oscillatingly disposed within the crushing box and connected to the drive assembly. The drive assembly includes a drive member and a pusher member. The pusher member includes a pusher seat and a movable rod. The drive member is used to drive the pusher seat to move. One end of the movable rod is hinged to the pusher seat, and the other end of the movable rod is hinged to the swing jaw plate.

[0006] Furthermore, the movable jaw component includes a swing jaw plate and a cover, the cover being fitably mounted on the swing jaw plate.

[0007] Furthermore, a conversion element is provided between the driving element and the pushing element. The conversion element is mounted on the frame, the driving element is connected to the conversion element, and the conversion element is connected to the pushing element.

[0008] Furthermore, the conversion component includes two fixed cylinders and a pneumatic component disposed between the two fixed cylinders, with the two fixed cylinders fixedly mounted on the frame; Both of the fixed cylinders are equipped with rotating shafts, and the ends of the two rotating shafts that are far apart from each other are respectively connected to a first pulley and a second pulley.

[0009] Furthermore, the pneumatic component includes a base plate frame and two gear rings fixedly mounted on the base plate frame. Each gear ring is fixedly connected to a corresponding fixed cylinder. Each gear ring contains a gear, and an eccentric rod is connected between the two gears. Two connecting rods are connected to both ends of the eccentric rod, and the two connecting rods are respectively connected to the two rotating shafts. A hinge rod is sleeved in the middle of the eccentric rod.

[0010] Furthermore, a sleeve is fixedly installed at the bottom of the seat plate frame, a piston column is slidably connected inside the sleeve, a push rod is fixedly installed on the piston column, both ends of the push rod completely penetrate the piston column, and the bottom end of the hinge rod is hinged to the top end of the push rod.

[0011] Furthermore, a tie rod is hinged to the bottom of the swing jaw plate, the tie rod is slidably mounted on the frame, and a spring is sleeved on the tie rod. The spring, through the tie rod, tends to drive the swing jaw plate away from the crushing roller.

[0012] Furthermore, the oscillating jaw plate has teeth formed on the side near the crushing roller.

[0013] Furthermore, the driving component includes a motor, the output shaft of which is connected to a drive pulley, and a first belt is tensioned between the drive pulley and the first pulley; A driven pulley is coaxially fixedly connected to the crushing roller, and a second belt is tensioned between the driven pulley and the second pulley.

[0014] Furthermore, a groove is formed on the crushing roller, and a plurality of crushing hammers are hinged in the groove.

[0015] The beneficial effects of this utility model are: This application utilizes a drive assembly to drive the moving jaw to swing in conjunction with the crushing roller to crush materials. The drive assembly transmits power to the pusher via a conversion component, causing the pusher to drive the movable rod, which in turn drives the swinging jaw plate to periodically swing towards the crushing roller for compression and crushing. Simultaneously, the spring on the bottom tie rod of the swinging jaw plate stores energy during crushing and releases its elastic energy at the end of the crushing stroke, assisting the swinging jaw plate to quickly and reliably reset, preparing space for the next crushing operation. Traditional excavators can only process one concrete block at a time. When faced with a large number of blocks to be crushed, the process is time-consuming, labor-intensive, and lengthy. This application places the concrete blocks into a crushing box for crushing, meeting the requirements of large-scale projects for efficient processing and the need for recycled concrete aggregates in different projects. By using a drive assembly to drive the moving jaw to cooperate with the crushing roller, continuous and batch crushing operations can be achieved, processing a large number of concrete blocks in a short time, significantly improving crushing efficiency, meeting the requirements of large-scale projects for efficient processing, and accelerating the overall progress of the project.

[0020] This embodiment proposes a concrete block crushing structure, such as... Figures 1 to 8 As shown, the assembly includes a frame 1, a crushing component 2, and a drive component 3. The crushing component 2 and the drive component 3 are fixedly mounted on the frame 1. The crushing component 2 includes a crushing box 21, a moving jaw 22, and at least one crushing roller 23 disposed within the crushing box 21. In this embodiment, it is preferred that the number of crushing rollers 23 is one. The moving jaw 22 is oscillatingly disposed within the crushing box 21 and connected to the drive component 3. The drive component 3 is used to drive the moving jaw 22 to move closer to or away from the crushing roller 23 to cooperate in crushing materials. The moving jaw 22 includes a swing jaw plate 221 and a cover 222. The top of the swing jaw plate 221 is rotatably mounted on the crushing box 21, and the cover 222 is openably mounted on the swing jaw plate 221. The drive component 3 is configured to drive the swing jaw plate 221 to swing toward the crushing roller 23 to perform the crushing operation.

[0021] In this embodiment, after the drive assembly 3 is started, it drives the swing jaw plate 221 to swing periodically toward the crushing roller 23 (i.e., Figure 5 The swing jaw plate 221 swings left and right, thereby squeezing and crushing the construction waste (such as waste concrete blocks without steel bars) that is put in into the crushing box 21.

[0022] In a preferred embodiment, the drive assembly 3 includes a drive member 31, a conversion member 32, and a pusher member 33. The conversion member 32 is mounted on the frame 1. The drive member 31 is connected to the conversion member 32, the conversion member 32 is connected to the pusher member 33, and the pusher member 33 is connected to the moving jaw member 22. The conversion component 32 includes two fixed cylinders 321 fixed on the frame 1 and a pneumatic component 322 disposed between the two fixed cylinders 321. A rotating shaft 323 is rotatably disposed inside each of the two fixed cylinders 321. The ends of the two rotating shafts 323 that are far apart from each other are respectively connected to a first pulley 324 and a second pulley 325. The pneumatic component 322 includes a base plate frame 3221 and two gear rings 3222 fixedly mounted on the base plate frame 3221. Each gear ring 3222 is fixedly connected to the corresponding fixed cylinder 321. A gear 3223 is disposed inside each gear ring 3222. An eccentric rod 3224 is rotatably connected between the two gears 3223. Two connecting rods 3225 are connected to both ends of the eccentric rod 3224. The two connecting rods 3225 are respectively connected to the two rotating shafts 323. A hinge rod 3226 is sleeved in the middle of the eccentric rod 3224. In one possible embodiment, the design may also be carried out without using gears 3223. A sleeve 3227 is fixedly installed at the bottom of the seat plate frame 3221. A piston column 3228 is slidably connected inside the sleeve 3227. A push rod 3229 is fixedly installed on the piston column 3228. Both ends of the push rod 3229 completely penetrate the piston column 3228. The bottom end of the hinge rod 3226 is hinged to the top end of the push rod 3229.

[0023] In this embodiment, the drive unit 31 drives the first pulley 324 to rotate via belt transmission, which in turn drives the rotating shaft 323 inside the fixed cylinder 321 to rotate. This rotation is transmitted to the eccentric rod 3224 via the connecting rod 3225, causing it to make eccentric circular motion around the center of the rotating shaft 323. The hinge rod 3226 in the middle of the eccentric rod 3224 swings up and down with the eccentric motion, and drives the push rod 3229 and piston rod 3228 hinged to it to make reciprocating linear motion in the sleeve 3227. At the same time, the reciprocating linear motion at the bottom of the push rod 3229 is converted into the periodic swing of the swing jaw plate 221 toward or away from the crushing roller 23 through the transmission of the push seat 331 and the movable rod 332, thereby performing the crushing operation on the material.

[0024] The pusher 33 includes a pusher seat 331 and a movable rod 332. The bottom of the push rod 3229 is fixedly connected to the pusher seat 331 through the sleeve 3227. The left end of the movable rod 332 is hinged to the pusher seat 331, and the right end of the movable rod 332 is hinged to the swing jaw plate 221. A pull rod 333 is hinged to the bottom of the swing jaw plate 221. The pull rod 333 is slidably mounted on the frame 1. A spring 334 is sleeved on the pull rod 333. The spring 334 has a tendency to drive the swing jaw plate 221 away from the crushing roller 23 through the pull rod 333 (that is, a tendency to drive the swing jaw plate 221 to move to the left). When the push rod 3229 moves upward under the piston drive, it drives the push seat 331, which is fixedly connected to the bottom, to rise together. The push seat 331 converts the upward thrust into a horizontal thrust towards the crushing roller 23 through the movable rod 332 hinged to it, driving the swing jaw plate 221 to swing to the right around its upper hinge point towards the crushing roller 23 to perform the crushing operation. At the same time, the pull rod 333 at the bottom of the swing jaw plate 221 is pulled and slides in the slide of the frame 1. The spring 334 sleeved on the pull rod 333 is thus compressed and stores energy. When the crushing stroke ends and the push rod 3229 begins to move downward under the drive assembly 3, the push seat 331 descends accordingly. At this time, the compressed spring 334 releases its stored elastic energy and applies a pull force away from the crushing roller 23 to the bottom of the swing jaw plate 221 through the pull rod 333, assisting and ensuring that the swing jaw plate 221 quickly and reliably returns to its original position, thereby preparing space for the next feeding and crushing stroke.

[0025] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
