Description

The cassava stalk crusher

Background technology

The utility model relates to a kind of broken broken machine that uses roller, the disintegrating machine of especially broken straw.

Background technology

Stalk with plant also is the developing direction of the present ecological agriculture in the field.The cassava plantation is easy, and the output height has very high economic worth.Cassava also is widely used in industrial circle except that the food of doing people and animal and fowl fodder, especially make alcohol with it, and alcohol is and one of the renewable sources of energy of rich using value.The stalk of cassava generally all abandons, and is very unfortunate.With the stalk of cassava also in the field, be to develop eco-agriculture, keep its sustainable development, be plantation of present cassava and the important subject utilized, the departments concerned is attached great importance to the research of this respect, but because cassava stalk complex-shaped, big or small and different in size, the soft or hard program is also different, be beneficial to also field to its broken frustillatum, does not also find well the cassava branch stalk crusher with the stalk fragmentation of cassava at present on the domestic market.The cassava stalk is hereinafter to be referred as the cassava stalk.Again according to close documents and materials, as patent " 86106458, cotton stalk crusher ", patent " 90217134.8, the wooden material crusher of Chinese herbal medicine ", patent " 03205228.6, straw crusher ", patent " 200420025602.4 kibbler roll " do not find a kind of type of very suitable cassava stalk fragmentation, their complex structures yet, manipulate inconvenience, production efficiency is low, and production and maintenance cost are big, and improper peasant carries out broken actual use to the cassava stalk.

Summary of the invention

The purpose of this utility model provides the broken broken machine of a kind of cassava stalk, it can solve run in the cassava stalk shattering process complex-shaped, length, not of uniform size, do the problem that wet degree and hard crisp not equal characteristics cause processing difficulties, and it is simple in structure, easy to operate and efficient height, produce and maintenance cost low.

The technical scheme that the utility model is taked: the part of rolling adopts roll shaft type structure, and roll shaft is provided with some wedge type grooves, and each movable blades then is fixed on these wedge type grooves with wedge type piece and clamp-screw respectively; The extruding baffle plate is installed below the inner end of charging aperture, and this extruding baffle plate and roll shaft surface form a cavity from big to small, when roll shaft rotates, make the extruding baffle plate also play the suction effect when material enters, and extruding the place ahead, baffle plate inner end is equipped with fixed blade.Material is squeezed by charging aperture cavity from big to small under the absorption of roll shaft rotation and extruding baffle plate.The movable blades and the tangent place of fixed blade that advance on the roll shaft when material promptly are cut off fragmentation, and the material after the chopping is discharged from discharging opening rapidly under the effect of inertia and charging extruding.Like this, at roll shaft constantly under the acting in conjunction of rotation and extruding baffle plate, material is cataclasm and realize fragmentation by movable blades through pushing after earlier;

Steady for machine run, the utility model is provided with an inertial flywheel at an end of roll shaft, utilizes flywheel storage and effect of inertia, makes the problem that runs into the operation shakiness when the stalk of broken unlike material obtain solution.

The utility model is simple in structure, has high efficiency, operation and safe and reliable, maintenance is convenient, characteristics such as cost is low except that as the fragmentation of cassava stalk, also can be carried out fragmentation to cotton stalk, cornstalk, sugarcane and leaf, straw etc., be to be fit to the agricultural crop straw fragmentation of vast farmers use also in the field, the desirable type that develops eco-agriculture.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a sectional structure schematic diagram of the present utility model.

Fig. 2 is the structural representation that Fig. 1 analyses and observe along the M-M line.

Fig. 3 is that A looks the primary structure schematic diagram among Fig. 1.

Fig. 4 is the structural representation of the another kind of blade of the utility model.

In Fig. 1～4, support 1, loam cake 2, roll shaft 3, wedge type piece clamp-screw 4, wedge type piece 5, movable blades 6, charging aperture 7, extruding baffle plate 8, the extruding baffle plate is regulated hinge pin 9, regulate seat board 10, fixed blade 11, fastening and adjustment screw 12, fixed blade clamp-screw 13, fixed blade seat board 14, discharging opening 15, loam cake hinge pin 16, the extruding baffle plate is regulated jack bolt 17, inertial flywheel 18.

Embodiment

In Fig. 1, loam cake 2 usefulness hinge pins 16 are actively connected on the support 1, and loam cake 2 can be raised, and can install and overhaul each member on the roll shaft 3.The two ends of roll shaft 3 constitute rolling by bearing with support 1 and connect.Equilateral respectively interval has 3 wedge type grooves on roll shaft 3, with wedge type briquetting 5 and clamp-screw 4 movable blades 6 is being fixed on the wedge type groove of running roller 3 respectively on the wedge type groove.In like manner, can be at some wedge type grooves that have on the roll shaft 3 more than two or 3, and be fixed with corresponding movable blades 6, its operation principle is constant.Movable blades 6 is many more, and the fineness of broken material is more little.Be provided with extruding baffle plate 8 in the inner of charging aperture 7 bottom surfaces.Fixed blade 11 usefulness fixed blade clamp-screws 13 are fixed on the fixed blade seat board 14 of support 1, and place inner the place ahead of stripper plate 8.Movable blades 6 has points of tangency with fixed blade 11 near above stripper plate 8 inner termination in clockwise rotating.Hinge pin 9 and 1 movable connection of support are passed through in the outside of extruding baffle plate 8, and the inner is fixedly connected with adjusting seat board 10 by fastening and adjustment screw 12.Discharging opening 15 is positioned at the lower left of roll shaft 3.
