Description

A kind of high-efficiency multi-function crops pulverizer

Technical field

The utility model relates to farm machinery, specifically a kind of high-efficiency multi-function crops pulverizer.

Background technology

Existing agricultural mill mainly is a hock type series pulverizer, it adopts the soft formula smashing principle that hits, moving pawl on the rotating disk and the pawl of deciding on the door closure combine, stir and the bump material with the high speed that per minute 5000 changes above, under the wind-force effect that rotating disk produces, blow out reaching the fine powder of pulverizing purpose.Its defective is that the material crushing efficiency in the cavity is low, and is more fastidious to the material that need are pulverized.

Summary of the invention

The purpose of this utility model provides a kind of crush efficiency height, is widely used in to pulverize various crops and high-efficiency multi-function crops pulverizer energy-conservation, easy to use.

The technical solution of the utility model is: the transmission device that the crops pulverizer comprises frame, casing, is contained in the motor on the frame and connects with motor, the broken knife rest that it is characterized in that being installed in the casing on the frame is cross cutter hammer, and the cutter hammer is made of the tup of hammer body, hammer end, the square hock and the fan at hammer body middle part; Tup is connected the end of hammer body, and square hock and fan are connected the middle part of hammer body, and cross cutter hammer is connected with negative pulley wheel by axle.

Its feature also is the structure of tup for to be linked by two square bars and hammer body top, opens two square guiding gutters and the guiding gutter vertical direction is opened a square cut groove along cutter hammer gyratory directions.Fan is welded by four square band steels and hammer body.The first half in the casing is provided with the roll flute bar.Belt pulley in the transmission device is the recessed inertia belt sheave structure of wheel circle, can strengthen the inertia of belt pulley.Replace the threshing that cross cutter hammer can be used as barley and wheat, cereal, rape etc. with the disengaging dish.

Crops pulverizer of the present utility model adopts hard beating type and the soft formula principle of combining of hitting, compare with common hock type, under the identical condition of overall dimensions, original machine power, crush efficiency to the dried particles thing improves 40%, crush efficiency to dry straw kind can improve 150～200%, has advanced design, external form is small and exquisite, the production efficiency height, motor load is light, energy-conservation, characteristics easy to use can be widely used in the pulverizing and the threshing of the common corn in rural area, barley and wheat, cereal, straw bran etc., and have satisfied effect.Because the particularity of its structure, can also cut up with a hay cutter cattle and sheep feeds such as cutting straw, fresh straw after removing screen cloth, can be widely used in the family, rural culture, have incomparable efficient of hock type and purposes.

Among the figure, 1-hopper, 2-material switch, 3-door closure, 4-roll flute bar, 5-casing, 6-axle bed, 7-moving belt pulley, 8-screen cloth, 9-sieve basket, 10-cross cutter hammer, 11-final drive shaft, 12-hulling disk, 10-1-hammer body, 10-2-square hock, 10-3-fan, 10-4-tup.

The specific embodiment

Embodiment: as shown in Figure 1, 2, crops pulverizer of the present utility model by frame, casing, be contained in the motor on the frame and the transmission device that connects with motor etc. is formed, the broken knife rest that is installed in the casing on the frame is cross cutter hammer 10, and the cutter hammer is made of the tup 10-4 of hammer body 10-1, hammer end, the square hock 10-2 and the fan 10-3 at hammer body middle part; Tup 10-4 is connected the end of hammer body 10-1, and square hock 10-2 and fan 10-3 are connected the middle part of hammer body 10-1, and cross cutter hammer 10 passes through axle and is connected with negative pulley wheel 7.Fan 10-3 is welded by four square band steels and hammer body, shown in Fig. 3,4, the structure of tup 10-4 is the square shaped teeth that linked by two square bars and hammer body top, open two square guiding gutters and the guiding gutter vertical direction is opened a square cut groove along cutter hammer gyratory directions, work to reduce resistance and rise to impact hook and cut material in cutter when running hammer, can improve barycenter, improve moment of inertia, storage power lightens the load.The first half in the casing is provided with roll flute bar 4, and its installation form becomes the effect of stranding mill as shown in Figure 5 with the cutter capitate, and the fragmentations of straw kind crops is had efficient effect.

Square hock except that having soft fragmentation of hitting formula, when crushed straw class crop, also the tool volume, cut effect, have auxiliary charging function.Fan produces wind-force when the high speed rotary of cutter hammer, the fine powder that reaches crushing effect is blown out cavity (if the fine powder that produces in the crushing process can not in time blow out cavity, prime mover load increases, and may damage prime mover when serious).Belt pulley 7 in the transmission device is the recessed inertia belt sheave structure of wheel circle.

During work, the material that needs to pulverize is put into hopper, and all seamed edges of the square hock at the middle part of cross cutter hammer and cutter hammer have effect of impact to the material in the cavity, and the material after preliminary fragmentation is made the high speed circular motion in cavity under the stirring of cutter hammer.Be distributed in the housing inner periphery under action of centrifugal force equably, material is further rubbed mill with the hands between cutter peen portion and roll flute, reach further pulverizing.Fine powder is discharged from the sieve screen apertures of bottom, thereby is finished whole crushing process under the extruding of cutter hammer and under the fan wind-force double action.When being threshing such as barley and wheat, cereal, rape, replacing cross cuttves hammer 10 with disengaging dish 12 and use as threshing.
