Through the coordinated operation of a drive gear, fixed rod, drive motor, conical grinding sleeve, conical grinding table, grinding balls, and driven gear, this concrete block crusher facilitates the rotation of the conical grinding sleeve around the conical grinding table, further crushing the initially pulverized concrete and achieving a secondary crushing function. Therefore, compared to existing technologies, this crusher can more finely crush concrete with better crushing results.

[0004] However, when the concrete block crusher is damaged, the opening device is not easy to lift, making it difficult for maintenance personnel to disassemble and repair the damaged parts inside, which affects the maintenance cost and reduces the maintenance efficiency of the equipment.

[0005] Meanwhile, its concrete block crusher uses a secondary crushing process to fully break down the blocks, but there is no screening structure inside the device, which may result in uneven crushing of the raw materials after crushing, reducing the processing effect of the device and affecting the processing quality.

[0006] Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing concrete block crusher. Utility Model Content

[0007] The purpose of this utility model is to provide a concrete block crusher for mortar production, in order to solve the problems mentioned in the background art, such as the difficulty in conveniently lifting and opening the device when damage occurs, which makes it difficult for maintenance personnel to disassemble and repair the damaged parts inside, affecting the maintenance and repair costs and efficiency of the device. At the same time, the lack of a screening structure inside the device may result in uneven crushing of the raw materials after crushing, reducing the processing effect of the device and affecting the processing quality.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a concrete block crusher for mortar production, comprising: a machine body shell, and a cover provided on the upper side of the machine body shell, wherein a first drive motor is provided inside the cover, and a crushing block is provided at the lower end of the first drive motor;

[0009] Also includes:

[0010] The positioning frame is installed inside the outer shell of the machine body, and a crushing frame is provided on the inner side of the positioning frame. A first limiting rod is connected to the outer side of the upper end of the crushing frame, and an installation plate is installed in the middle opening of the lower side of the crushing frame. A screening screen body is provided inside the installation plate.

[0011] A cleaning brush is installed at the lower end of the crushed block, and a guide ring is provided on the upper side of the crushed block. A drive assembly is provided on the left side of the machine cover, and a second push frame is installed on the right side of the machine cover. A second limit rod is connected to the upper side of the second push frame, and a guide plate is provided on the lower side of the second push frame.

[0012] In one possible implementation, the drive assembly includes a first push frame mounted on the left side of the hood, with a drive rod connected to the lower side of the first push frame, and a second drive motor mounted on the lower side of the drive rod.

[0013] In one possible implementation, the drive rod is threadedly connected to the first push frame, and the first push frame is engaged with the cover.

[0014] In one possible implementation, the crushing frame and the positioning frame are engaged relative to each other, and the first limiting rod is threadedly connected to both the crushing frame and the positioning frame.

[0015] In one possible implementation, the screening mesh body and the mounting plate are engaged relative to each other to limit the installation of the screening mesh body, and the screening mesh body is symmetrically arranged about the central axis of the mounting plate, wherein the shape and structure of the screening mesh body is semi-circular.

[0016] In one possible implementation, the broken block is arranged to rotate relative to the guide ring, and the longitudinal section of the guide ring is a "T"-shaped structure to guide and limit the rotation trajectory of the broken block.

[0017] In one possible implementation, the second pusher is slidably disposed relative to the guide plate, and the guide plate has an "I" shaped structure.

[0018] In one possible implementation, a discharge rod is provided in the middle of the mounting plate, and a limit frame is installed at the lower end of the discharge rod.

[0019] In one possible implementation, the crushed block is engaged with the discharge rod, and the discharge rod is rotatably mounted relative to the limiting frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: When a concrete block crusher for mortar production is damaged, the lifting and opening device is easy to use, allowing maintenance personnel to easily disassemble and repair damaged internal parts, reducing maintenance costs and improving maintenance efficiency. Furthermore, the internal screening structure prevents uneven crushing of raw materials, improving the processing effect and quality of the equipment, resulting in better performance. Specific details are as follows:

[0021] 1. The screen body is fixed inside the crushing frame by the mounting plate and crushing frame, so that the screen body can screen the crushed raw materials and prevent raw materials that do not meet the crushing requirements from being discharged to the lower side, thereby improving the processing effect and processing quality of the device.

[0022] 2. The first drive motor, in conjunction with the crushing block, pushes the discharge rod to rotate along the mounting plate and the limit frame inside the machine body shell, so that the discharge rod pushes the crushed material to be discharged from the inside of the machine body shell, avoiding the blockage of the device by a large amount of discharged material, and improving the discharge efficiency of the device;

[0023] 3. The device is opened and unfolded by pushing the first push frame and the machine cover upward along the second push frame and the guide plate by the second drive motor and the drive rod. This allows maintenance personnel to easily rotate the first limit rod. At this time, the first limit rod relaxes its limit on the positioning frame and the crushing frame, which makes it easier for operators to disassemble and maintain the crushing frame, improve the maintenance and repair efficiency of the device, and reduce the maintenance cost of the device.

[0030] 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.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a concrete block crusher for mortar production, comprising: a machine body shell 1, an anti-slip pad 2, a positioning frame 3, a crushing frame 4, a first limiting rod 5, a mounting plate 6, a screening screen body 7, a discharge rod 8, a limiting frame 9, crushed blocks 10, a cleaning brush 11, a machine cover 12, a first drive motor 13, a guide ring 14, a drive assembly 15, a first push frame 1501, a drive rod 1502, a second drive motor 1503, a second limiting rod 16, a second push frame 17, and a guide plate 18;

[0032] Firstly, as Figure 1 , Figure 2 and Figure 4As shown, the second drive motor 1503 drives the drive rod 1502 to rotate inside the outer casing 1. Because the drive rod 1502 is threadedly connected to the first pusher frame 1501, the drive rod 1502 pushes the second drive motor 1503 and the cover 12 to move upwards. Since the second pusher frame 17 is slidably connected to the guide plate 18, as the cover 12 is pushed upwards by the drive assembly 15, it causes the second pusher frame 17 and the second limiting rod 16 to slide upwards along the guide plate 18, opening the upper side of the outer casing 1. At this time, the raw material to be crushed is poured into the upper side of the outer casing 1. Simultaneously, the second drive motor 1503 drives the drive rod 1502 to rotate in the opposite direction, causing the cover 12 and the second pusher frame 17 to reset along the guide plate 18. Then, the first drive motor 13 drives the crushed block 10... Rotating under the guide ring 14 causes the first drive motor 13 to work with the crushing frame 4 installed inside the positioning frame 3 to crush the raw materials. Since the crushing frame 4 is equipped with an installation plate 6 and a screen body 7, the screen body 7 filters the crushed raw materials, trapping the raw materials that do not meet the crushing standards on the upper side of the screen body 7. At the same time, since the crushed block 10 is equipped with a cleaning brush 11 on the lower side, the crushed block 10 drives the cleaning brush 11 to clean the upper side of the screen body 7 during rotation, preventing the raw materials from clogging the upper side of the screen body 7 and improving the screening effect of the screen body 7. The raw materials that meet the crushing standards fall into the lower side of the crushing frame 4 through the screen body 7, preventing the raw materials that do not meet the crushing requirements from being discharged to the lower side, improving the processing effect of the device and improving the processing quality of the device.

[0033] Secondly, as Figure 1 , Figure 2 and Figure 3 As shown, the first drive motor 13 drives the crushing block 10 to rotate inside the outer shell 1 of the machine body. Since the crushing block 10 is engaged with the discharge rod 8, the crushing block 10 engages and limits the discharge rod 8, causing the crushing block 10 to push the discharge rod 8 to rotate synchronously inside the outer shell 1 of the machine body. At this time, the discharge rod 8 rotates along the limit frame 9 at the lower end of the outer shell 1, pushing the crushed raw material to the lower side, so that the discharge rod 8 stirs and pushes the screened raw material, preventing the crushed raw material from agglomerating into lumps and blocking the inside of the device. At this time, the raw material is discharged through the lower opening of the outer shell 1 to the inside of the anti-slip pad 2, reducing the possibility of the device clogging, avoiding the need for operators to frequently unclog the discharge port of the device, reducing the cleaning and maintenance cost of the device, and improving the discharge efficiency of the device.

[0034] Finally, as Figure 1 , Figure 3 and Figure 5As shown, when the device is damaged, by rotating the second limiting rod 16, the second limiting rod 16 rotates upward and disengages from the outside of the cover 12. At this time, the maintenance personnel can pull upward to remove the cover 12 and the crushed block 10. Due to the threaded connection between the first limiting rod 5 and the crushing frame 4 and the positioning frame 3, the maintenance personnel can easily rotate the first limiting rod 5. At this time, the first limiting rod 5 rotates outward to relax its limiting on the positioning frame 3 and the crushing frame 4. At the same time, because of the engaging connection structure between the crushing frame 4 and the positioning frame 3, the operator can easily pull upward to remove the crushing frame 4 and simultaneously pull upward to pull the screening screen body 7, so that the screening screen body 7 is disengaged from the inside of the mounting plate 6. This facilitates the operator to quickly disassemble the device for disassembly and maintenance, reduces the difficulty of maintenance and repair, improves the efficiency of device maintenance and repair, and reduces the maintenance cost of the device.
