Fig. 1 is please referred to Fig. 4.

The crushing drying device for stalk that the present embodiment provides, including：Casing 1, feed hopper 4 and discharge bucket 5, charging Bucket 4 is communicated to the left end of casing 1 from top, and discharge bucket 5 passes to the right-hand member of casing 1 from bottom；Blast pipe 6 and discharge pipe 7, air intake One end of pipe is communicated to the right-hand member of casing from bottom, and the other end of blast pipe is connected with hot air source (not shown), discharge pipe 7 One end the horizontal other end of casing 1 is communicated to from top；The multiple rollers in the same direction and synchronous axial system being arranged in casing 1 2a, 2b, 2c, 2d, multiple roller 2a, 2b, 2c, 2d are extended longitudinally and are transversely arranged in order, multiple roller 2a, 2b, 2c, 2d Axis be respectively positioned in same plane P, be angularly positioned apart from six in each roller 2a, 2b, 2c, 2d whole circumference Tooth row.By taking roller 2a as an example, be angularly positioned apart from its whole circumference six tooth row 201a, 202a, 203a, 204a, 205a, 206a, tooth row 201a, 202a, 203a, 204a, 205a, 206a are extended longitudinally, each tooth row 201a, 202a, 203a, The upper radially outwardly projecting multiple rectangle crushing teeths (unmarked) being spaced apart of formation of 204a, 205a, 206a.

Wherein, multiple roller 2a, 2b, 2c, 2d initial phase are identical, i.e., whenever any to tooth in the tooth row of a roller When row is turned in plane, a pair of tooth rows of other rollers are also turned in plane.For example, tooth row 201a on roller 2a, When 201b is turned on plane P, a pair of tooth rows 201b, 204b on roller 2b are also rotated on plane P.

Roller 2a, 2b tooth row outer surface are mutually complementary, and similarly, the tooth row outer surface of every two two adjacent rollers is equal It is mutually complementary.When multiple roller 2a, 2b, 2c, 2d are axially rotated, the rotary speed direction level at its bottom tangent edge is towards a left side (such as Fig. 1 It is shown).

Offered correspondingly vertically in multiple roller 2a, 2b, 2c, 2d set hot water circuit chamber 20a, 2b0,20c, 20d.These hot water circuit chambers 20a, 20b, 20c, 20d longitudinal one end are provided with a water inlet, and the other end is provided with a water outlet Mouthful.One end of one water pipe (not shown) successively sequentially concatenates hot water circuit chamber 20d from right to left.I.e. a water pipe is sequentially connected heat Water circulation chamber 20d water inlet, hot water circuit chamber 20d delivery port, hot water circuit chamber 20c water inlet, hot water circuit chamber 20c Delivery port, hot water circuit chamber 20b water inlet, hot water circuit chamber 20b delivery port, hot water circuit chamber 20a water inlet, heat After water circulation chamber 20a delivery port, the water inlet end of a hot water circulating device is recycled to.The other end of water pipe then connects hot water and followed The water side of loop device.Wherein, a return conveyer (not shown) is arranged in casing 1 and positioned at the lower section of roller.Return conveyer Discharge end be arranged on the surface of feed hopper 4.

So, when the tooth row 204a on roller 2a is turned on plane P, tooth row 204a and roller 2b on roller 2a On tooth row 201b complementally splits, thus stalk can be made by shearing between tooth row when roller 2a, 2b are rotated further With being broken into segment particle, and partial particulate can successfully be carried out down from the tooth row 204a that tooth row 204a is transported to roller 2b Primary fragmentation.And blanking then by return conveyer from feed hopper returning charge to casing in crush again.The stalk of the present invention can be from edge Transverse shifting and residence time are long, rolling degree is big, thus can obtain more sufficiently drying and crushing.And enter from warm-air pipe Entering the hot blast in casing can also make stalk carry out heated-air drying in which turn left from the bottom up, from the right side, also pass through the hot water in roller Circulation carries out contact drying, therefore its drying efficiency is further higher..Wherein, hot air source can be common generation hot blast Device, such as can be the combination of heating resistor and blower fan.

In some other embodiments, wherein, angularly it is positioned apart from any idol in the whole circumference of each roller Several tooth rows.Preferably, in other examples, one end inwardly of tooth row forms T-shaped projection (unmarked) towards tangential direction, T-slot (unmarked) that is raised corresponding with T-shaped and extending longitudinally is formed in roller.So, tooth row can be facilitated Ground is arranged in roller, and stability is higher during operation.

Preferably, in other examples, crushing drying device also includes two baffle plates 3, and two baffle plates 3 correspond Ground approaches multiple roller 2a, 2b, 2c, 2d longitudinal both ends from outside.So, can prevent stalk from roller 2a, 2b, 2c, Fall on 2d.

In various embodiments above, it is preferable that roller 2a, 2b, 2c, 2d can be sequentially reduced, and can so make to lean in casing The flow resistance of nearly roller 2d side hot blast is smaller, discharge bucket nearby can be preferably dried, volume drying effect It is good.

In various embodiments above, plane P can be horizontal plane, can also horizontal plane tilt.When plane P and horizontal plane During inclination, roller 2a, 2b, 2c, 2d axis height reduce successively.So, stalk can be made to be more easy to move in casing.

The non-detailed portion of other in the present invention belongs to prior art, therefore will not be repeated here.

Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to The technical scheme described in foregoing embodiments can so be modified, either which part or all technical characteristic are entered Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology The scope of scheme.
