Description

Straw double end cuber

Technical field

The utility model belongs to agricultural machinery technological field, and what relate to is a kind of straw cuber.

Background technology

Development along with agricultural cience and farming techniques, when grain yield increases, the quantity of straw superfluous phenomenon also occurred in original application, though the formulation of " straw also field " in the agricultural production is arranged, but also also there is the problem of technology and economic aspect in the effect of the straw in a field performance anticipation, and quantitatively also is not proved to be The more the better in field also.Straw is as domestic fuel, and is for a long time far away, is still one of China's rural area main fuel so far.In the last few years, save non-renewable energy resources, kept sustainable development, become global common recognition.Keep and enlarge the straw use that acts as a fuel, still have its realistic meaning.But straw is loosely organized, and density is low, and it is few to go into the stove quality, therefore, only is applicable to farmers''s chamber of a kitchen range of dispersion, can not be used for the strong firepower of needs, and the long period burning is concentrated, the combustion apparatus of big heat heat exchange.

Summary of the invention

The purpose of this utility model is to provide a kind of straw cuber, crop stalk or forestry waste are compressed into highdensity, alternative coal is used for bigger combustion apparatus or is converted to gas-fired equipment, overcome the limitation of existing straw in the use that acts as a fuel, improve the availability of straw, save non-renewable energy resources.

The utility model is by support, feed bin, feeding screw, first discharge chambe, punch, die, guide shaft, connecting rod, cam, flywheel, drive motors is formed, and the annexation of each member is: feed bin is installed on the support, and rod for stiring materials is arranged at the feed bin bottom, two discharging openings is arranged at the bottom of the feed bin.Two feeding screws are arranged under the discharging opening, and feeding screw is made up of the screw propulsion blade in outer cylinder and the cylinder.The first discharge chambe that the feeding screw front end is connected mutually has the punch of compression once more in the first discharge chambe, at the discharge chambe front end die is arranged.Punch is installed on the guide shaft in the guide pin bushing that matches with the discharge chambe shell, and guide shaft by cam driven, is equipped with flywheel through connecting rod on the camshaft.Cam, feeding screw and rod for stiring materials are by separately motor driven.More than be basic scheme of the present utility model.

Good effect of the present invention is: can only be processed into highdensity as the crop stalk or the forestry waste of rural area single household kitchen range top fuel, alternative coal is used for bigger combustion apparatus or is converted to gas-fired equipment, overcome the limitation of existing straw in the use that acts as a fuel, enlarge the scope of application of straw, promptly alleviate the burden that the straw surplus causes, saved non-renewable energy resources again.

Embodiment

With steel plate or angle steel welding frame 1, with steel plate welding octagonal feed bin 2, the high 200mm of feed bin, octagon circumcircle diameter 1900mm, open two wide 300mm in the end of feed bin upper edge with the center of circle, bottom surface symmetry, the discharging opening 3 of long 390mm, electric motor driven rod for stiring materials 4 that rotates around the feed bin axis is arranged at the feed bin bottom.Under two discharging openings of feed bin, two feeding screws 5 are installed respectively, the outer cylinder diameter 200mm of spiral propeller, helical blade pitch 90mm, the long 500mm of feeder, two square first discharge chambes 6 of the discharging termination of spiral propeller, the long 250mm of first discharge chambe, wide 300mm, high 300mm, compression box rear portion dress guide shaft cover, dress guide shaft 7 in the cover, the guide shaft front end is installed punch 8, the long 250mm of punch, diameter 75 mm install taper matrix 9 on the square chest of the discharge chambe of punch front end, be surrounded by the electric heater of power 2KW on the die and control the temperature detect switch (TDS) of temperature 250 ℃ market sale, die is worked under this temperature, be convenient to the compression of straw.The rear end of guide shaft 7 connects connecting rod 10, the other end of connecting rod is enclosed within on the cam 11, cam 11 be the installing hole that passes the disalignment on the cylinder with a d-axis, and the structure that both are fixed, present embodiment cam diameter 290mm, the cam axle center and the cam center of circle make piston obtain the stroke of 120mm, cam, connecting rod, guide shaft, punch at a distance of 60mm, after the installation site of die concerned that satisfying depression bar 8 withdraws from from die, its front end was 100mm from die mouth maximum distance.Punch walks to foremost, enters recessed 20mm.Two cams on the camshaft are installed phase differences 180 degree, make the direction of motion of punch of two cover forming machanisms opposite all the time, and camshaft one end is installed power input wheel, and the other end is installed flywheel 12.The power 37KW of cam drive motors 13, power 5 KW of feeding screw drive motors 14, behind reducing gear, the camshaft revolution is 350 rev/mins, and the revolution of feeding screw is 200 rev/mins, and the revolution of rod for stiring materials is 20 cycle per minutes.

The course of work of present embodiment is: the straw oven dry, be crushed to the long section of 20mm with cracker in addition, with fan blower, air duct particle wind is delivered to feed bin 2, after particle is deposited at the bottom of the feed bin, transfer to bin outlet 3 by driving lever 4, enter feeding screw 5, advance pressurization through helical blade, than the fine and close first discharge chambe 6 that enters, the straw particle of punch 8 front ends is pressed into die by punch in the first discharge chambe, and straw is under pressure and action of high temperature, further compressed slivering, release from the die outlet, after the segment, promptly obtain density and be about 800kg/m ³The straw briquetting, this kind straw briquetting can be supplied with the user, substitutes the coal, the wet goods fuel that use at present.
