Abstract

The invention discloses a vertical shaft multistage board hammer sand making machine, and belongs to the technical field of the sand making equipment. The problems that the board hammer cannot beat gravels between the adjacent board hammers in the crushing since the board hammers of the existing vertical shaft board hammer are fixedly arranged at intervals and the crushing range is relatively small are solved. The sand making machine comprises a rack, a main case, a metal screen drum, a driving motor, a board hammer rotor and aboard hammers; an umbrella-shaped baffle plate is fixedly arrangedabove the board hammer rotor through an outer ring board, a fixed rod penetrates through the center of the board hammer rotor, and a driving mechanism is arranged between the board hammer rotor and the umbrella-shaped baffle plate; the driving mechanism comprises a first bevel gear, a second bevel gear, a crankshaft and a connecting rod, and further comprises a dust collection device. By arrangingthe board hammer rotor, the fixed rod and the driving mechanism, the board hammers are driven to swing up and down through the cooperation of the board hammer rotor, the fixed rod and the driving mechanism, the crushing range is enlarged, the crushing speed is higher, and the crushing efficiency is improved; a dust collection device is provided, and the dust is discharged after being sufficientlywashed, and the environment and the health of the worker cannot be influenced.

Description

technical field

[0001] The invention relates to the technical field of sand making equipment, in particular to a vertical shaft type multi-stage blow bar sand making machine. Background technique

[0002] Natural sand is a non-renewable resource in a short period of time. With the rapid development of my country's infrastructure, natural sand is almost exhausted. At the same time, due to the devastating damage to resources and the environment caused by excavation of sand and gravel, many cities have banned the use of natural sand due to factors such as flood control, environmental protection, and resource protection. Vertical shaft sand making machine is a kind of building material sand making equipment developed in recent years, which can crush rocks, ores or natural pebbles and other stones into industrial sand to replace natural sand.

[0003] Existing vertical shaft crushers mostly adopt a single-layer or two-layer rotor structure, and the blow bars installed on the rot...

Examples

Embodiment 1

[0020] see Figure 1~2 , in an embodiment of the present invention, a vertical shaft multi-stage blow bar sand making machine includes a frame 1, a casing 3, a metal screen cylinder 4, a driving motor 2, a blow bar rotor 7 and a blow bar 5, and the frame 1 is installed with an organic casing 3 through screws, and a metal screen cylinder 4 is concentrically fixed in the casing 3 through a support rod. The top of the metal screen cylinder 4 is open, and the metal screen cylinder 4 is equipped with a blow bar rotor 7, and the bottom of the blow bar rotor 7 is concentric. The hollow shaft 16 is welded and fixed, and the hollow shaft 16 extends to the bottom of the frame 1. On the frame 1, the drive motor 2 is installed on both sides of the casing 3 through bolts. The output shaft of the drive motor 2 is connected to the hollow shaft through the belt transmission member 14. 16 connection, both sides of the top of the casing 3 are provided with feed hoppers 11, both sides of the bot...

Embodiment 2

[0022] see image 3 The difference between this embodiment and Embodiment 1 is that it also includes a dust suction device, which includes a suction fan, a dust removal box 23 and a spray pipe 25, and both sides of the top of the casing 3 are equipped with suction The air pipe 22 is connected to the air outlet of the exhaust fan, and the other end of the air pipe 22 runs through the top of the dust removal box 23 and extends to the bottom of the inner cavity of the dust removal box 23. A partition 24 is fixed in the middle of the inner cavity of the dust removal box 23. Below 24 is a water storage chamber, and air holes are provided on the partition 24. A spray pipe 25 is installed on the top of the dust removal box 23, and a plurality of nozzles are integrated at the bottom of the spray pipe 25, and a water supply pipe is connected to the spray pipe 25. , the exhaust fan extracts the air with a large amount of dust and then passes it into the dust removal box 23 through the a...
