Detailed ways

As shown in the accompanying drawings, the fully automatic pulverizer of the utility model includes a crushing chamber 1 with a feed inlet and a discharge port, a rotor 5 is arranged in the crushing chamber 1, a crushing hammer 4 is installed on the rotor, the rotor and The structure of the crushing hammer 4 is a known technology, and will not be repeated here. the

As shown in Fig. 1 and Fig. 2, a feed bin 9 is fixedly connected to the entrance of the crushing chamber 1, and a feeder 2 is arranged in the feed bin 9, and the feeder 2 includes a rotating shaft 21, a wheel 22, a feeding Hammer 23, mounting shaft 24, positioning shaft 25, rotating shaft 21 are horizontally installed on the storehouse wall of feeding bin 9 by bearing, disc-shaped wheel disc 22 is fixedly installed on the rotating shaft 21, on the wheel disc 22, with rotating shaft 21 More than two installation shafts 24 are arranged symmetrically for the center, and a positioning shaft 25 is also fixedly installed on the wheel disc 22 on the same side of each installation shaft 24, and a feed hammer 23 is installed on the installation shaft 24, and the feed hammer One end of 23 has a mounting hole, and mounting shaft 24 is inserted in the mounting hole. As shown in Figure 2, in order to improve the mechanical strength, a plurality of wheel discs 22 can be installed in parallel on the same rotating shaft 21. At this time, the installation shaft 24 and the positioning shaft 25 also pass through these wheel discs 22 at the same time, and the feed hammer 23 is installed on the On the installation shaft 24 between the two wheel discs 22, the function of the positioning shaft 25 is to limit the range of motion of the feed hammer 23, so that it can only swing back and forth on the installation shaft 24, but cannot rotate 360 degrees, and it can also avoid feeding hammer 23. The hammer 23 strikes the rotating shaft 21 during operation.

At the entrance of the crushing chamber 1 between the feeder 2 and the rotor 5, a secondary feeder shaft 10 is arranged, and a feeder plate 19 is fixedly installed on the secondary feeder shaft 10, and the secondary feeder shaft 10 is connected with the feeder The device 2 is connected through a transmission belt transmission.

One end of rotating shaft 21 passes outside the feed bin 9, and a gearbox 69 and a belt pulley 6 are installed at the end outside the feeding bin 9 at the rotating shaft 21, which is connected with the power mechanism transmission by the belt installed on the pulley.
