Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, and particularly relates to a crushing and grinding machine for cement product processing. Background Art

[0002] Cement products are articles poured with cement during the building construction process. During the current cement pouring process, defective products are likely to occur due to operation errors. For resource recycling, the defective products need to be broken and ground first.

[0003] For example, the utility model with the publication number CN217450465U discloses a crushing and grinding machine for cement product processing, which includes a processing box. Support frames are fixedly arranged on the opposite sides of the processing box. A connecting plate is fixedly arranged on one side of the processing box, and a crushing component is installed on the other side of the connecting plate. Two first motors and two second motors are fixedly installed on the processing box, and the two first motors are located directly above the two second motors. Two crushing rollers and two grinding rollers are rotatably connected between the opposite inner walls of the processing box through bearings. In this utility model, the first motor drives the crushing rollers to rotate, so that the two crushing rollers cooperate with each other to crush the cement products, reducing the volume of the cement products, and enabling them to be better ground by the grinding rollers and grinding blocks driven by the second motor. The setting of the first filter plate can sort and filter the crushed cement products, preventing the cement products from blocking between the two second guide plates, and ensuring the smooth and stable grinding of the cement products.

[0004] During the implementation of this application, it is found that this technology has the following problems: Most existing crushing and grinding machines for cement product processing use two groups of crushing rollers to crush cement products to reduce their volume for better grinding. However, most cement products contain steel bars inside. When the cement products are introduced into the crushing and grinding machine, the inside of the grinding machine is prone to blockage or damage, thus reducing the practicality of the equipment.

[0005] Therefore, a crushing and grinding machine for cement product processing is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problem that most cement products contain steel bars inside, and when the cement products are introduced into the crushing and grinding machine, the inside of the grinding machine is prone to blockage or damage. The utility model provides a crushing and grinding machine for cement product processing.

[0007] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0008] A pulverizing and grinding machine for cement product processing, comprising a pulverizing and grinding machine main body. The pulverizing and grinding machine main body includes a pulverizing cylinder. A clamping groove is formed on one side of the pulverizing and grinding machine main body away from the pulverizing cylinder. A pretreatment mechanism capable of screening cement and steel bars is installed inside the clamping groove of the pulverizing and grinding machine main body. A supporting mechanism capable of restricting the moving range of the pretreatment mechanism is installed on the lower surface of the pretreatment mechanism. A driving mechanism capable of pushing the cement blocks inside the pretreatment mechanism is installed on one side of the pretreatment mechanism away from the pulverizing and grinding machine main body.

[0009] Furthermore, the pretreatment mechanism includes a fixing plate. One side of the fixing plate close to the pulverizing cylinder is clamped inside the clamping groove of the pulverizing and grinding machine main body. Two groups of limiting plates are installed on the upper surface of the fixing plate. An L-shaped fixing plate is installed on the back surface of the fixing plate. A hydraulic cylinder is installed at the top of the inner wall of the L-shaped fixing plate. An extrusion plate is installed at the output end of the hydraulic cylinder. A connecting plate is clamped on one side adjacent to the two groups of limiting plates. A clamping groove is formed on one side of the connecting plate close to the pulverizing and grinding machine main body. Two groups of fastening plates are slidably connected inside the clamping groove of the connecting plate. Thread holes are formed on the upper surfaces of the two groups of fastening plates. Bolts are threadedly connected inside the two groups of fastening plates.

[0010] Furthermore, anti-slip pads are bonded to one side adjacent to the two groups of fastening plates.

[0011] Furthermore, a feed inlet is formed at the top of the pulverizing and grinding machine main body. The lower surfaces of the ends of the two groups of limiting plates away from the driving mechanism are both located directly above the feed inlet of the pulverizing and grinding machine main body.

[0012] Furthermore, the driving mechanism includes an L-shaped connecting plate. An electric telescopic rod is installed on the inner side wall of the L-shaped connecting plate. The output end of the electric telescopic rod is installed on one side of the connecting plate away from the pulverizing and grinding machine main body.

[0013] Furthermore, the supporting mechanism includes a supporting plate. The upper surface of the supporting plate is installed on the lower surface of the fixing plate. One side of the supporting plate close to the pulverizing cylinder abuts against one side of the pulverizing and grinding machine main body away from the pulverizing cylinder. A connecting block is installed on the front surface of the supporting mechanism. A thread hole is formed on one side of the connecting block away from the pulverizing and grinding machine main body. A screw is threadedly connected inside the connecting block. The external thread of the screw passes through the connecting block and is connected to the inside of the pulverizing and grinding machine main body.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The utility model moves two sets of fastening plates to the upper and lower sides of the internal steel bars of the cement product respectively, and then installs bolts into the threaded holes of the two sets of fastening plates by rotating the bolts, so that the two sets of fastening plates are fixedly connected to the upper and lower sides of the internal steel bars of the cement product respectively. By starting the hydraulic cylinder to push the extrusion plate to extrude the cement product, the cement block and the steel bar are separated, and the two sets of fastening plates limit the moving position of the steel bar, thereby minimizing the situation that the internal steel bars of the cement product enter the main body of the pulverizing and grinding machine when the subsequent cement block is introduced into the main body of the pulverizing and grinding machine, resulting in blockage of the main body of the pulverizing and grinding machine. Therefore, the pulverizing efficiency of the main body of the pulverizing and grinding machine is improved.

[0016] 2. The utility model passes through the rotating screw, passes the screw through the connecting block and connects it to the inside of the main body of the pulverizing and grinding machine, so that the screw and the screw limit the moving position of the support plate. Then, the support plate is installed between the main body of the pulverizing and grinding machine and the fixing plate, so that the support plate supports the fixing plate, thereby minimizing the movement of the fixing plate during use. Therefore, the stability of the fixing plate during use is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As Figures 1 to 4 shown, a pulverizing and grinding machine for cement product processing includes a pulverizing and grinding machine main body 1. The pulverizing and grinding machine main body 1 includes a pulverizing cylinder 2. A card slot is provided on one side of the pulverizing and grinding machine main body 1 away from the pulverizing cylinder 2. A pretreatment mechanism 3 capable of screening cement and steel bars is installed inside the card slot of the pulverizing and grinding machine main body 1. A support mechanism 5 capable of restricting the moving range of the pretreatment mechanism 3 is installed on the lower surface of the pretreatment mechanism 3. A driving mechanism 4 capable of pushing the cement blocks inside the pretreatment mechanism 3 is installed on one side of the pretreatment mechanism 3 away from the pulverizing and grinding machine main body 1. Specifically, the steel bars inside the cement product are separated by the pretreatment mechanism 3, so as to avoid as much as possible the steel bars inside the cement product entering the inside of the pulverizing and grinding machine main body 1 when the subsequent cement blocks are introduced into the inside of the pulverizing and grinding machine main body 1, resulting in blockage inside the pulverizing and grinding machine main body 1. Therefore, the pulverizing efficiency of the pulverizing and grinding machine main body 1 is improved. The cement blocks inside the pretreatment mechanism 3 are pushed by the driving mechanism 4, thus reducing the labor consumption of the staff when operating the device. Therefore, the practicability of the device is improved. The pretreatment mechanism 3 is supported by the support mechanism 5, so as to avoid as much as possible the movement of the pretreatment mechanism 3 during use. Therefore, the stability of the pretreatment mechanism 3 during use is improved.

[0027] As Figures 1 to 3As shown, the pretreatment mechanism 3 includes a fixing plate 301, a side of the fixing plate 301 close to the pulverizing barrel 2 is clamped in the slot of the pulverizing and grinding machine body 1, two groups of limiting plates 302 are installed on the upper surface of the fixing plate 301, an L-shaped fixing plate 303 is installed on the back of the fixing plate 301, a hydraulic cylinder 304 is installed on the top of the inner wall of the L-shaped fixing plate 303, and an extrusion plate 305 is installed on the output end of the hydraulic cylinder 304, and a connecting plate 307 is clamped on the adjacent side of the two groups of limiting plates 302, and a slot is provided on the side of the connecting plate 307 close to the pulverizing and grinding machine body 1, and two groups of fastening plates 306 are slidably connected in the slot of the connecting plate 307, and threaded holes are provided on the upper surfaces of the two groups of fastening plates 306, and bolts 308 are connected to the internal threads of the two groups of fastening plates 306; The structure is that after the cement product containing steel bars is placed on the upper surface of the fixing plate 301, the two sets of fastening plates 306 are respectively moved to the upper and lower sides of the steel bars inside the cement product, and then the bolts 308 are rotated and installed into the threaded holes of the two sets of fastening plates 306, so that the two sets of fastening plates 306 are respectively fixedly connected to the upper and lower sides of the steel bars inside the cement product, and the extrusion plate 305 is pushed by starting the hydraulic cylinder 304 to extrude the cement product, so that the cement block and the steel bars are separated, and the two sets of fastening plates 306 limit the moving position of the steel bars, so as to avoid the steel bars inside the cement product from entering the inside of the crushing and grinding machine body 1 when the subsequent cement block is introduced into the inside of the crushing and grinding machine body 1 as much as possible, thereby improving the crushing efficiency of the crushing and grinding machine body 1.

[0028] At the same time, by positioning the fixed plate 301 on one side of the top of the crushing and grinding machine body 1, the staff can push the cement blocks accumulated on the fixed plate 301 into the interior of the crushing and grinding machine body 1 by pushing the connecting plate 307, so that subsequent staff do not need to move the pre-treated cement blocks on the upper end of the fixed plate 301 back and forth, thereby improving the practicality of the equipment; by snapping the fixed plate 301 into the card slot of the crushing and grinding machine body 1, the fixed plate 301 can be removed from the card slot of the crushing and grinding machine body 1, thereby facilitating the staff to regularly replace and maintain the pretreatment mechanism 3.

[0029] like Figure 3 As shown, the adjacent sides of the two sets of fastening plates 306 are bonded with anti-skid pads 309; specifically, when the two sets of fastening plates 306 are clamped to the upper and lower ends of the steel bars inside the cement product, the two sets of anti-skid pads 309 are located between the connection points of the two sets of fastening plates 306 and the steel bars, so that the two sets of anti-skid pads 309 increase the friction between the contact surfaces of the two sets of fastening plates 306 and the steel bars, thereby minimizing the movement of the steel bars when they are clamped inside the two sets of anti-skid pads 309 and causing the steel bars to fall into the inside of the crushing and grinding machine body 1.

[0030] like Figure 1 and Figure 2As shown, a feed inlet is provided at the top of the main body 1 of the crushing and grinding machine. The lower surfaces of the two ends of the two limiting plates 302 away from the driving mechanism 4 are both located directly above the feed inlet of the main body 1 of the crushing and grinding machine. Specifically, by abutting the adjacent sides of the two limiting plates 302 against the front and rear sides of the connecting plate 307, the movement path of the connecting plate 307 is restricted by the two limiting plates 302. Then, since one end of the two limiting plates 302 is located directly above the feed inlet of the main body 1 of the crushing and grinding machine, the two limiting plates 302 guide the cement blocks moving at the upper end of the fixing plate 301 into the main body 1 of the crushing and grinding machine, thus minimizing the chance that the cement blocks will fall to the ground when the staff pushes the connecting plate 307 to drive the cement blocks at the upper end of the fixing plate 301 to move. Therefore, the safety of the device during use is improved.

[0031] As Figure 1 and Figure 2 shown, the driving mechanism 4 includes an L-shaped connecting plate 401. An electric telescopic rod 402 is installed on the inner side wall of the L-shaped connecting plate 401, and the output end of the electric telescopic rod 402 is installed on the side of the connecting plate 307 away from the main body 1 of the crushing and grinding machine. Specifically, before the staff pushes the connecting plate 307 to push the accumulated cement blocks at the upper end of the fixing plate 301 into the feed inlet of the main body 1 of the crushing and grinding machine, by starting the electric telescopic rod 402 to push the connecting plate 307 to move, the electric telescopic rod 402 replaces manual pushing of the connecting plate 307 to move, thus reducing the labor consumption of the staff when operating the device. Therefore, the practicality of the device is improved.

[0032] As Figure 1 and Figure 4 shown, the supporting mechanism 5 includes a supporting plate 501. The upper surface of the supporting plate 501 is installed on the lower surface of the fixing plate 301. One side of the supporting plate 501 close to the crushing cylinder 2 abuts against the side of the main body 1 of the crushing and grinding machine away from the crushing cylinder 2. A connecting block 502 is installed on the front surface of the supporting mechanism 5. A threaded hole is provided on the side of the connecting block 502 away from the main body 1 of the crushing and grinding machine. A screw 503 is threadedly connected inside the connecting block 502, and the external thread of the screw 503 passes through the connecting block 502 and is connected to the inside of the main body 1 of the crushing and grinding machine. Specifically, after the fixing plate 301 is installed into the card slot of the main body 1 of the crushing and grinding machine, by rotating the screw 503, the screw 503 passes through the connecting block 502 and is connected to the inside of the main body 1 of the crushing and grinding machine, so that the screw 503 and the screw 503 restrict the moving position of the supporting plate 501. Then, since the supporting plate 501 is installed between the main body 1 of the crushing and grinding machine and the fixing plate 301, the supporting plate 501 supports the fixing plate 301, thus minimizing the chance that the fixing plate 301 will move during use. Therefore, the stability of the fixing plate 301 during use is improved.

[0033] Meanwhile, one side of the support plate 501 close to the main body 1 of the crushing and grinding machine is detachably connected to the side of the main body 1 of the crushing and grinding machine away from the crushing cylinder 2 through the connecting block 502 and the screw 503, so that the support plate 501 can be disconnected from the side adjacent to the main body 1 of the crushing and grinding machine during use, thus minimizing the obstruction of the subsequent workers from normally disassembling and replacing the fixing plate 301 by the support plate 501.

[0034] In summary: After the cement product containing steel bars is placed on the upper surface of the fixing plate 301, the two fastening plates 306 are respectively moved to the upper and lower sides of the steel bars inside the cement product, and then by rotating the bolt 308, the bolt 308 is installed into the threaded holes of the two fastening plates 306, so that the two fastening plates 306 are respectively fixedly connected to the upper and lower sides of the steel bars inside the cement product, and the extrusion plate 305 is pushed by starting the hydraulic cylinder 304 to extrude the cement product, so that the cement block and the steel bar are separated, and the moving positions of the two fastening plates 306 to the steel bar are restricted, thus minimizing the entry of the steel bars inside the cement product into the main body 1 of the crushing and grinding machine when the subsequent cement blocks are introduced into the main body 1 of the crushing and grinding machine, and therefore improving the crushing efficiency of the main body 1 of the crushing and grinding machine.

[0035] Meanwhile, before the worker pushes the connecting plate 307 to push the cement blocks accumulated at the upper end of the fixing plate 301 into the feeding port of the main body 1 of the crushing and grinding machine, the electric telescopic rod 402 is started to push the connecting plate 307 to move, so that the electric telescopic rod 402 replaces the manual labor to push the connecting plate 307 to move, thus reducing the labor consumption of the worker when operating the device, and therefore improving the practicability of the device; after the fixing plate 301 is installed in the clamping groove of the main body 1 of the crushing and grinding machine, by rotating the screw 503, the screw 503 is passed through the connecting block 502 and connected to the inside of the main body 1 of the crushing and grinding machine, so that the screw 503 and the screw 503 restrict the moving position of the support plate 501, and then by installing the support plate 501 between the main body 1 of the crushing and grinding machine and the fixing plate 301, the support plate 501 supports the fixing plate 301, thus minimizing the movement of the fixing plate 301 during use, and therefore improving the stability of the fixing plate 301 during use.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the principles described in the above embodiments and the specification are only the principles of the present invention.
