Detailed Description

In order to solve the cutting that current crushing apparatus adopts two kinds of comminution device combinations to cut up mostly, can only cut up the straw, can't grind it into powder, can't make into the technical problem of degradable drinking cup and tableware etc, the embodiment of the utility model provides a crop straw cutting grinding device. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the embodiment provides a crop straw cutting and grinding device, which includes a box body 1, a blade 6, a rotating shaft 7 and two motors 10, wherein the blade 6 is fixedly installed on the rotating shaft 7, the blade 6 is used for crushing straws, the rotating shaft 7 is rotatably installed on the upper side wall of the inner cavity of the box body 1, an output shaft of one of the motors 10 is fixedly connected with the rotating shaft 7, and the motor 10 drives the rotating shaft 7 and the blade 6 to rotate, so as to perform a first-step crushing operation on straws.

The lower side wall fixed mounting of 1 inner chamber of box has bracing piece 2, 2 upper ends fixed mounting of bracing piece have lower mill 3, 3 upper ends of lower mill rotate and install runner stone 4, and runner stone 4 and lower mill 3 are used for the straw crocus, and 1 lateral wall fixed mounting of box has the motor 10 that provides power for runner stone 4, and motor 10 drives runner stone 4 and rotates, carries out second step crocus operation to the straw of smashing.

In this embodiment, the fixed ann of the lower extreme of runner stone 4 changes and has axis of rotation 44, and the setting of axis of rotation 44 more does benefit to the rotation of runner stone 4, runner stone 3 upper end seted up with axis of rotation 44 assorted rotation groove 32 down, stability when runner stone 4 rotates can be guaranteed to rotation groove 32 and axis of rotation 44, provides a stable center of rotation for runner stone 4, prevents that runner stone 4 from dropping when rotating.

The 4 lateral walls of head stone are provided with hold-in range 9, the other end of hold-in range 9 is connected with band pulley 101, and hold-in range 9 is used for driving the rotation of head stone 4, and the tooth's socket that matches each other with the latch on the hold-in range 9 is seted up to head stone 4 lateral wall, the output shaft interconnect of band pulley 101 and motor 10, motor 10 drive band pulley 101 and rotate, and band pulley 101 drives hold-in range 9, and hold-in range 9 drives head stone 4 and rotates, carries out the crocus to the straw.

In further example, the top lateral wall fixed mounting baffle 5 of runner stone 4, baffle 5 make the straw of smashing fall into runner stone 4 completely, ring channel 41 has been seted up to runner stone 4 upper end, and ring channel 41 is used for storing the straw that the top fell, continues processing on next step to the straw, the inside fixed mounting of ring channel 41 has abrasive brick 42, and abrasive brick 42 grinds the straw at the rotation in-process, and the straw after will smashing further crocus operation of going forward, 3 upper end fixed mounting of runner stone has unsmooth piece 31, and unsmooth piece 31 makes the grinding more abundant.

In the process of the rotation of the upper grinding disc 4, the grinding block 42 provides centrifugal force to the straw powder under the action of friction force, so that the straw powder moves outwards, enters between the upper grinding disc 4 and the lower grinding disc 3, continues to be ground, finally breaks away from the upper grinding disc 4 and falls into the lower grinding disc 3, and is discharged from the discharge hole.

The upper end of the grinding block 42 is of an inverted V-shaped structure, so that the crushed aggregates above the grinding block can fall into the annular groove 41 conveniently, and cannot be left at the upper end of the grinding block 42, and material residue is prevented.
