Embodiment 1

[0030] Such as figure 1 As shown, the raw material crushing device for the preparation of ecological building materials includes a horizontal crushing cylinder 3, the top of the crushing cylinder 3 is connected with a feed hopper 14, and the right side of the bottom of the crushing cylinder 3 is connected with a discharge channel 7, and the discharge channel 7 is inclined downward. set up. A cleaning mechanism for cleaning long fibers is detachably connected to the discharge channel 7 through bolts. In this embodiment, the cleaning mechanism adopts a screen 8 .

[0031] Grinding shaft 2 is horizontally installed in the pulverizing tube 3, and both ends of the pulverizing shaft 2 are connected in rotation with the pulverizing tube 3, and the left end of the pulverizing shaft 2 extends out of the pulverizing tube 3 and is connected with a motor 12. The crushing shaft 2 is radially welded with some crushing knives 1, and a hollow knife rest 4 is horizontally installed below the ...

Embodiment 2

[0037] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the left end of the crushing shaft 2 is keyed to a driving bevel gear 18, the driven bevel gear 18 is meshed with a driven bevel gear 16, and the driven bevel gear 16 is coaxially connected with a Cam 17, the vertical left end of tooth bar 9 is welded with push pedal 19, and cam 17 offsets with push pedal 19 intermittently. A working box 15 is welded on the outer wall of the left end of the crushing cylinder 3, and the driving bevel gear 18, the driven bevel gear 16, the cam 17 and the push plate 19 are all arranged in the working box 15, which can prevent the above-mentioned components from being polluted and extend the above-mentioned components to a certain extent. service life.

[0038]When the crushing shaft 2 rotates, the driving bevel gear 18 can drive the driven bevel gear 16 to rotate, thereby driving the cam 17 to rotate, and the cam 17 intermittently pushes the rack 9...

Embodiment 3

[0040] like image 3 As shown, the difference between the present embodiment and the second embodiment is that the cleaning mechanism is a cleaning shaft 21 on which several cleaning needles are radially welded. The external motor 12 drives the cleaning shaft 21 to rotate, and the long straw fibers in the discharge channel 7 can be hooked on the cleaning needles, and the screening effect of the long fibers is better than that of the screen 8 .

Abstract

The invention relates to the technical field of crushing devices, in particular to a raw material crushing device for preparing ecological building materials. The device includes a crushing cylinder;the top of the crushing cylinder is communicated with a feeding hopper, the bottom of the crushing cylinder is communicated with a discharge channel, a crushing shaft is transversely arranged in the crushing cylinder, a plurality of crushing cutters are radially arranged on the crushing shaft, and a cutter support is transversely arranged under the crushing shaft and positioned above the dischargechannel; the end, away from the discharge channel, of the cutter support is hinged to the crushing cylinder, the other end of the cutter support is detachably connected with the crushing cylinder, aplurality of cleaning cutters for cleaning away straw wound around the crushing shaft are vertically arranged on the cutter support, and the cleaning cutters intersect with the crushing cutters. The device solves the problem that since the straw is likely to be wound round the crushing shaft during crushing, the crushing effect is influenced.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to a raw material crushing device for preparing ecological building materials. Background technique [0002] Ecological building materials refer to building materials that have little impact on the environment, are energy-saving and material-saving, and are environmentally friendly. Straw is one of the most commonly used raw materials for ecological building materials, and it is often used to prepare concrete. [0003] When using straw to prepare concrete, the straw needs to be crushed. In the prior art, the straw crushing is mostly operated by a drum-type pulverizer. The top of the pulverizer is fed and the bottom is discharged. There are also many long fibers in the straw. In addition, the straw is easily entangled on the crushing shaft during the crushing process, which affects the crushing effect of the straw. Contents of the invention [0004] The present invention...
