Abstract

The corn stalk crushing and throwing machine includes one frame, one spiral throwing cutter with one shaft mounted through rolling bearing onto the frame, one horizontal pressing wheel mounted through sliding bearing onto the frame, one hood and guide plates in the back part of the hood. It features the increased groups of blades mounted homogeneously onto the cutter shaft and the guide plates mounted through an angle regulating mechanism. During operation, the high speed rotating blades produce axial force to through the crushed stalk homogeneously in certain angle range.

Description

Corn strew grinding return-to-field machinery

Affiliated technical field

The invention provides a kind of corn strew grinding return-to-field machinery that has flabellum, belong to agricultural machinery technological field.

Background technology

At present general straw crushing and field-returning machine is many by frame, hood, press wheel, swivel knife shaft, fixedly tool rest, flail knife, deflector etc. are formed.Press wheel is installed in the rear lower of hood by sliding bearing; Swivel knife shaft is installed on the hood by rolling bearing, fixedly tool rest is that line evenly is welded on the cutter shaft in the shape of a spiral, moving knife and fixedly tool rest generally by bolted, the both sides and the frame of hood weld together, a plurality of deflectors are welded on the posterior medial of hood, direction is vertical with hood, and identical with the unit direction of advance.Such straw crushing and field-returning machine makes the stalk after pulverizing vertically to shed.Because the fabric width of straw cutting apparatus makes straw cutting apparatus when operate as normal less than the width between two driving wheels of tractor like this, the stalk after the pulverizing is shed inhomogeneous in the field, the g and D of wheat after the influence.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can overcome above-mentioned this defective, make the stalk of pulverizing can cover uniform corn strew grinding return-to-field machinery.Its technical scheme is:

A kind of corn strew grinding return-to-field machinery, comprise the rack-mounted press wheel of flail knife, tool rest, frame and level, hood, deflector, wherein press wheel is installed in the rear lower of frame by sliding bearing, cutter shaft is installed on the frame by rolling bearing, tool rest line in the shape of a spiral evenly is fixed on the cutter shaft, flail knife is fixedlyed connected with tool rest, the rear portion of hood is provided with a plurality of deflectors, it is characterized in that: set up some groups of flabellums and be distributed on vertically on the cutter shaft, a plurality of flabellums in same group are certain inclination angle around the same circumference of cutter shaft and evenly distribute; Deflector is welded on the head of adjusting bolt and through adjusting the inboard that bolt is movably arranged on the hood rear portion, adjusts the angle of itself and direction of advance through guiding mechanism.

Described corn strew grinding return-to-field machinery is characterized in that: the flabellum group number of arranging on cutter shaft is 2～4 groups, and every group flabellum number is 3～5.

Described corn strew grinding return-to-field machinery, the inclination angle scope that is distributed on the flabellum on the same circumference of cutter shaft is 10～30 °.

Described corn strew grinding return-to-field machinery, guiding mechanism comprises connecting rod, measures dish and a plurality of adjustment handle, wherein each is adjusted and is set with an adjustment handle on the bolt, and adjust the outside that handle is positioned at hood, a plurality of adjustment handle correspondences are connected with connecting rod through bolt, measure dish and be welded on the outer wall of frame, the end that passes the frame outer wall with connecting rod is connected by bolt.

Described corn strew grinding return-to-field machinery, deflector number are 4～10.

Described corn strew grinding return-to-field machinery, the adjusting range of the water conservancy diversion angle of deflector is the boundary with the direction of advance, between ± 45 °.

The present invention compared with prior art has following advantage:

1, owing to axially is evenly equipped with some groups of flabellums along cutter shaft, a plurality of flabellums in same group are certain inclination angle around the same circumference of cutter shaft and evenly distribute, so during the straw crushing and field-returning machine operate as normal, the flabellum of high speed rotating produces certain axial force, the stalk after the pulverizing can be shed with fan-shaped;

2, deflector is welded on the head of adjusting bolt, be movably arranged on the inboard at hood rear portion, adjust the angle of itself and direction of advance through guiding mechanism, can adjust the fabric width scope of shedding, and then guarantee crushing straw shed fabric width greater than the width between two driving wheels of tractor, it is more even that stalk is shed.
