Description

Technical Field

[0001] The utility model relates to the technical field of quick-setting agent processing equipment, in particular to a concrete quick-setting agent grinding device. Background Art

[0002] Accelerators are additives added to concrete to make it set and harden quickly. The main types are inorganic salts and organic substances. They are powdered solids and are indispensable additives in shotcrete construction. Their function is to accelerate the hydration and hardening of cement and form sufficient strength in a very short time to achieve the purpose of rapid setting of concrete in emergency repairs or shafts. Accelerators usually need to be ground during production and processing, so special grinding devices are used.

[0003] A Chinese utility model patent with the announcement number CN218222628U discloses a device for grinding a finished product of an accelerating setting agent. The device can clean the accelerating setting agent on the drum by means of a brush plate, thereby preventing the accelerating setting agent from sticking to the drum and causing material waste. With respect to the above-mentioned related technology, the inventor believes that there are the following defects:

[0004] In actual use, the device lacks an integrated structure for cleaning the brush plate, so the quick-setting agent is easily attached to the bristles, making the bristles dirty, thereby reducing the cleaning effect of the roller. For this reason, we provide a concrete quick-setting agent grinding device. Utility Model Content

[0005] In order to solve the problem in the above background technology that the dirty bristles reduce the cleaning effect of the roller due to the lack of an integrated structure for cleaning the brush plate, the utility model provides a concrete quick-setting agent grinding device.

[0007] The anti-adhesion component includes a brush plate fixedly installed inside the grinding box, a lever arranged below the brush plate, a bracket fixedly connected to the lever, a slide plate symmetrically fixedly connected to the bracket, a sliding rod fixedly installed inside the grinding box and slidably connected to the slide plate, a spring sleeved on the outside of the sliding rod, a rotating shaft rotatably connected to the inside of the grinding box, and a cam symmetrically fixedly sleeved on the outside of the rotating shaft.

[0008] The filter material crushing assembly includes a hollow shaft rotatably connected to the top of the filter plate, a blade 1 equidistantly circumferentially fixedly connected to the outside of the hollow shaft, a solid shaft penetrating the hollow shaft and rotatably connected to the filter plate, a blade 2 equidistantly circumferentially fixedly connected to the outside of the solid shaft, an inner gear ring fixedly sleeved on the outside of the solid shaft, a gear disk equidistantly circumferentially rotatably connected to the inside of the hollow shaft and meshing with the inner gear ring, and an outer gear ring fixedly connected to the inner wall of the hollow shaft and meshing with the gear disk.

[0009] As a further improvement of the above solution, the top of the grinding box is fixedly connected to a feeding hopper, and the bottom of the inner cavity of the grinding box is designed as a funnel-shaped structure and is fixedly connected to a discharge pipe, which is convenient for adding materials and quickly discharging materials.

[0010] As a further improvement of the above scheme, one end of the two groups of grinding rollers are coaxially fixedly connected with gears and the gears are meshingly connected, and the other end of the grinding roller on one side is coaxially fixedly connected with a rotating motor to facilitate driving the two groups of grinding rollers to rotate inward at the same time.

[0011] As a further improvement of the above scheme, a driving motor is fixedly installed on the outside of the grinding box, and the rotor end of the driving motor is fixedly connected to a transmission shaft. The rotating shaft and one side of the transmission shaft are fixedly sleeved with transmission gears. The two sets of transmission gears are connected by a transmission belt transmission. The other end of the transmission shaft and the bottom end of the solid shaft are fixedly connected to conical wheels and the conical wheels are meshingly connected to each other, so as to drive the anti-adhesion component and the filter material crushing component to operate simultaneously.

[0012] As a further improvement of the above solution, the lengths of the blade one and the blade two are matched with the radius length of the filter plate, which can prevent material leakage during crushing.

[0013] As a further improvement of the above solution, the blade one and the blade two are staggered, and the cutting edges of the blade one and the blade two are oppositely arranged, so as to facilitate the chopping of large particles.

[0014] As a further improvement of the above solution, a connecting frame is fixedly installed inside the grinding box and is rotatably connected to the solid shaft. The top two sides of the connecting frame are inclined to prevent material residue.

[0016] 1. The utility model drives the transmission shaft to rotate through a driving motor, and utilizes the transmission cooperation of the transmission gear and the transmission toothed belt to drive the rotating shaft to rotate, and the rotating shaft drives the cam to rotate. The cam can regularly lift the bracket upward, and the sliding cooperation of the slide plate and the slide rod can drive the lever to move upward. When the cam rotates away from the bracket, the elastic action of the spring can be utilized to drive the lever to reset, and the vertical reciprocating movement of the lever can make the bristles be moved, so that the materials attached to the surface can be separated from it, thereby achieving the purpose of cleaning the bristles and effectively ensuring the cleaning effect of the grinding roller.

The utility model can drive the solid shaft to rotate through the rotation of the transmission shaft and the meshing action between the conical wheels, and utilizes the meshing action of the toothed disk, the inner gear ring and the outer gear ring to drive the hollow shaft to rotate in the opposite direction, thereby driving the blade one and the blade two to rotate in the opposite direction to chop the filtered material, thereby preventing the large particles of filtered material from accumulating on the filter plate and being difficult to clean, thereby affecting the filtration of fine materials. The utility model has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
