Description

Technical Field

[0001] This utility model relates to the field of manufactured sand processing technology, and in particular to a manufactured sand impact crushing mechanism. Background Technology

[0002] Manufactured sand refers to sand produced by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements, which can better meet daily needs.

[0003] After mining, manufactured sand needs to be crushed by a crusher for subsequent use. For example, the utility model disclosed in CN213408964U discloses an impact crusher for calcium carbonate mines, which mainly includes a lower casing, an upper casing, a drive shaft, a bearing seat, a through rod, a guard plate, a screen plate, a hammer, and a partition plate. The lower casing and the upper casing are connected by a flange. A pulley and a first flywheel are respectively installed on the drive shaft located at one end of the casing, and a second flywheel is installed on the drive shaft located at the other end of the casing. By controlling the rotor to cooperate with the crushing chamber, the material thrown out of the rotor outlet can impact and crush the material inside the crushing chamber, achieving an impact crushing effect.

[0004] However, the above-mentioned device only causes the material to be thrown from the discharge port into the crushing chamber for impact crushing. The material that is not completely crushed is not crushed again in the subsequent process, resulting in an unsatisfactory crushing effect, which affects the crushing effect and crushing efficiency.

[0021] like Figure 1-3 As shown, the present invention proposes a machined sand impact crushing mechanism, which includes a crushing chamber 1 and a feeding hopper 3 disposed at the upper end of the crushing chamber 1. The crushing chamber 1 is provided with crushing components 4 for crushing machined sand.

[0022] In this invention, the crushing component 4 can perform dual crushing treatment on the input manufactured sand, so that the manufactured sand can be crushed more thoroughly.

[0023] In an optional embodiment, the crushing component 4 includes two peripheral guard plates 41 fixedly connected to the inner wall of the crushing chamber 1. An impact head 410 is slidably connected to the inner wall of the crushing chamber 1 between the two peripheral guard plates 41. Support shafts 43 are rotatably connected to the front and rear side walls of the inner cavity of the crushing chamber 1, and turntables 44 are fixedly connected to the two support shafts 43. The turntables 44 are located below the inner side of the impact head 410. A connecting rod 45 is fixedly connected between the two turntables 44. Two push rods 46 are rotatably connected to the connecting rod 45, and one end of each push rod is hinged to the impact head 410. Guide plates 48 are fixedly connected to the left and right side walls of the inner cavity of the crushing chamber 1, and the guide plates 48 are symmetrically distributed below the peripheral guard plates 41. Two crushing rollers 47 are rotatably connected between the front and rear side walls of the inner cavity of the crushing chamber 1, and the rear end of the crushing rollers 47 penetrates the crushing chamber 1. The back of the crushing chamber 1 is provided with a drive assembly for driving the turntable 44 and the crushing roller 47 to rotate synchronously.

[0024] In this embodiment, when the turntable 44 driven by the drive component drives the push rod 46 on the connecting rod 45 to reciprocate and push the impact head 410 toward the side close to the peripheral guard plate 41, it can perform the first impact crushing on the introduced material. The material falling along the guide plate 48 can also be crushed again by the crushing roller 47, so that the material can be crushed twice and the crushing is more thorough, thereby improving the crushing effect and processing efficiency of the material.

[0025] It should be noted that both the peripheral guard plate 41 and the impact head 410 are V-shaped. The V-shaped peripheral guard plate 41 can guide the material while the impact head 410, which moves toward the peripheral guard plate 41, can crush the material. The lower end of the impact head 410 is fixedly connected to a guide rod 42 that passes through the guide plate 48, so as to improve the stability of the impact head 410 when it moves up and down along the vertical plane.

A transmission assembly 414 is provided on the left crushing roller 47 and the end of the rear support shaft 43 that passes through the crushing chamber 1.

[0028] In this embodiment, after the start-up drive motor 412 drives the rear support shaft 43 to rotate the rear turntable 44, the two turntables 44 can be driven to rotate synchronously through the connecting rod 45 between the two turntables 44. The rotating rear support shaft 43 can also drive the left crushing roller 47 to rotate synchronously through the transmission component 414, and then drive the two crushing rollers 47 to rotate synchronously through two meshing gears 413.

[0029] It should be noted that the transmission assembly 414 includes two pulleys, which are respectively fixedly connected to the left crushing roller 47 and the rear support shaft 43 through one end of the crushing chamber 1. The two pulleys are fitted with a transmission belt. Through the two pulleys and the transmission belt, the rotating rear support shaft 43 can drive the left crushing roller 47 to rotate synchronously. The transmission assembly 414 and the gear 413 are both located inside the support cover 411, which covers the transmission assembly 414 and the gear 413.

A pump body 22 is fixedly mounted on the water tank 21, the liquid inlet end of the pump body 22 is communicated with the water tank 21 through a pipe, the liquid outlet end of the pump body 22 is communicated with a water supply pipe 23 one end of which is communicated with the water guide frame 24, and a plurality of spray heads 25 are communicated with the inner side of the water supply pipe 23.

[0031] In this embodiment, the water flow delivered by the pump body 22 is sprayed out in a square shape through the spray heads 25 on the water guide frame 24, which can wet the fed machine-made sand, so as to reduce the impact of dust overflowed during the crushing process of materials on the surrounding environment.

[0032] It should be noted that the inside of the water guide frame 24 is hollow, both the water supply pipe 23 and the spray heads 25 are communicated with the hollow part of the water guide frame 24, the inner side of the water guide frame 24 is concave, and the plurality of spray heads 25 are equidistantly distributed in a square shape at the concave part of the water guide frame 24.

[0033] The working principle of the above embodiment is as follows: After the machine-made sand material to be crushed is fed through the feeding hopper 3, the driving motor 412 and the pump body 22 can be started respectively. After the started driving motor 412 drives the rear support shaft 43 to drive the rear turntable 44 to rotate, the connecting rod 45 between the two turntables 44 can drive the two support shafts 43 and the turntables 44 to rotate synchronously, and the connecting rod 45 driven by the turntables 44 can drive the push rod 46 on the connecting rod 45 to reciprocally push the impact head 410 to move reciprocally toward the side close to the peripheral guard plate 41, so as to perform primary impact crushing on the fed machine-made sand material; The rotating rear support shaft 43 can also drive the left crushing roller 47 to rotate synchronously through the transmission assembly 414, and after the two crushing rollers 47 are driven to rotate synchronously by two meshed gears 413, the primarily crushed machine-made sand material can fall onto the material guide plate 48 along the gap between the impact head 410 and the peripheral guard plate 41, then fall between the crushing rollers 47 along the material guide plate 48 and be crushed again by the crushing rollers 47; At the same time, the started pump body 22 delivers water flow into the water guide frame 24 through the water supply pipe 23, and then sprays the water out in a square shape through the spray heads 25 on the water guide frame 24, which can wet the fed machine-made sand, so as to reduce the impact of dust overflowed during the crushing process of materials on the surrounding environment.

[0034] 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.
