Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to fig. 1 and fig. 2, an embodiment of the present invention includes: a three-roller shredder comprises a box body 1, a feed hopper 2, a bracket 3, shredding rollers and a motor.

Wherein, 1 top of box corresponds is provided with feeder hopper 2 for drop into domestic waste, and the support 3 corresponds the support through the bottom, so that the ejection of compact of below.

The shredding roller transversely runs through and sets up on box 1 and correspond the drive through the motor for to domestic waste shredding. The shredding roller is provided with 3 first shredding rollers 4 including main drive and second shredding rollers 5 and third shredding rollers 6 of auxiliary drive, second shredding rollers 5 and third shredding rollers 6 set up side by side in box 1, first shredding roller 4 sets up the downside between second shredding roller 5 and third shredding roller 6 for the unloading interlock, just blade on first shredding roller 4 and the blade on second shredding roller 5 and the third shredding roller 6 are interlock alternately respectively, through first shredding roller 4 positive-negative rotation, and blade on first shredding roller 4 is cuted with the blade on second shredding roller 5 and the third shredding roller 6, with the material shredding.

The box 1 is still provided with screen cloth 7 in the correspondence of shredding roller below, with the garrulous less size of material, garrulous back material size can be adjusted according to the ejection of compact screen cloth aperture size of screen cloth 7.

The motor includes first motor 8, second motor 9 and third motor 10, first motor 8 drives first shredding roller 4, and first motor 8 adopts frequency conversion hydraulic motor for improve stability in use. The automatic shredding machine is characterized by further comprising a speed reducer, wherein the speed reducer comprises a first speed reducer 11 and a second speed reducer 12, and the second motor 9 and the third motor 10 correspondingly drive the second shredding roller 5 and the third shredding roller 6 through the first speed reducer 11 and the second speed reducer 12 respectively.
