Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1-4, the present invention provides a rhizome type fodder grinder, which comprises a grinding cylinder 100, which is a cylindrical cylinder, wherein a frame (not shown in the figure) is arranged outside the grinding cylinder and is vertically placed on the horizontal ground through the frame. The pulverizing barrel 100 has a top plate 110 and a bottom plate 120. The top plate 110 is provided with a feeding hole 111, and the bottom plate of the crushing barrel is provided with a discharging hole 121. The feeding opening 111 is provided with a feeding hopper 112, which is convenient for feeding the material to be crushed into the crushing cylinder 100.

The driving motor 130 is a speed reducing motor, and the driving motor 130 is fixedly installed above the top plate 110 of the crushing cylinder through a base; and a rotating shaft 140 coaxially disposed in the pulverizing cylinder 100, wherein an upper end of the rotating shaft 140 is fixedly connected to an output shaft of the driving motor 130.

A plurality of sets of rotary chopping knives, which are uniformly arranged on the rotary shaft 140 from top to bottom; wherein each set of rotary chopping blades comprises a plurality of chopping blades 150 mounted on the rotary shaft in the circumferential direction. The chopping blade 150 has three-sided cutting edges, i.e., edges other than the connection portion with the rotating shaft 140 are cutting edges.

A plurality of fixed chopping knives 160 evenly arranged on the inner wall of the crushing cylinder 100, the fixed chopping knives 160 being parallelogram double-edged blades, the cutting edges of which are arranged on a longer pair of paired edges. The stationary chopper 160 is fixedly attached to the inner wall of the crushing cylinder 100 by a mounting bracket 161. The cutting edge of the stationary chopper 160 is angled from the horizontal. Preferably, the included angle between the cutting edge of the fixed chopping knife and the horizontal plane is 50-70 degrees. To prevent the material from accumulating at the stationary chopper 160 when the included angle is too small, and not performing a good cutting action when the included angle is too large.

In the present embodiment, the fixed chopping blades 160 are arranged in a row, each fixed chopping blade 160 is installed at the same height, and the plurality of fixed chopping blades 160 are uniformly arranged on the inner wall of the pulverizing cylinder 100 in the circumferential direction, respectively. In another embodiment, the fixed shredding knives 160 are arranged in multiple rows, with different rows of fixed shredding knives 160 arranged at different heights.

The rhizome type fodder grinder further includes a grinding disk 170 coaxially disposed in the grinding cylinder 100 above the rotary chopper, the center of the grinding disk 170 being fixedly coupled to the rotary shaft 140. An annular feeding channel 171 is formed on the grinding disc 170, and the position of the annular feeding channel 171 corresponds to the position of the feeding hole 111. A plurality of connecting ribs 172 are provided radially in the annular feed channel 171 to ensure the overall structure of the grinding plate 170.

A bearing tray 180 is arranged between the grinding disc 170 and the chopping knife, the bearing tray 180 is sleeved on the rotating shaft 140, and the edge of the bearing tray 180 is fixedly connected with the inner wall of the crushing barrel 100. A plurality of discharging channels 181 are arranged on the bearing tray 180 along the circumferential direction, and the discharging channels 181 are arranged close to the inner wall of the crushing barrel.

In another embodiment, a plurality of grooves (not shown) are uniformly formed on the lower surface of the grinding plate 170, and the grooves are radially arranged along the grinding plate 170 to improve the grinding effect of the grinding plate 170.

The rhizome material is fed from the hopper 112 and enters the milling drum 100 through the inlet 111 and then enters the milling chamber between the retainer plate 180 and the milling disc 170 through the annular inlet channel 171. The grinding disc 170 is driven by the driving motor to rotate relative to the bearing tray 180, and the rhizomatic materials are rolled and then fall into the chopping cavity through the discharge channel 181. The rotary chopper rotates along with the rotary shaft 140 to chop the falling materials, and at the same time, the materials are splashed toward the inner wall of the crushing cylinder 100 by the rotary chopper, and are chopped again by the fixed chopper 160 provided on the inner wall of the crushing cylinder. Under the cooperation of the rotary shredding knife and the fixed shredding knife 160, the material shredding effect is better. The cut materials are discharged from the discharge hole 121.

Be equipped with the apron on the discharge opening 121, can cut up the condition or set for the time according to the material and open the apron, discharge the material after will cutting up.
