Abstract
The utility model discloses a wheat and rice straw grinder adopting biaxial crossed disk hobs. The straw grinder comprises a main frame, wherein a driving shaft and a driven shaft are rotationally mounted on the main frame; a plurality of groups of mutually-matched crossed biaxial crossed disk hob blades are mounted on the driven shaft respectively; and fixed cutter blades opposite to and matched with the crossed biaxial crossed disk hob blades are fixedly arranged on the inner wall of the lower part of the main frame. Through the adoption of the mechanism that the crossed biaxial crossed disk hob blade groups rotate and cut the straws and the hob blades rotate in a high speed and are matched with the fixed cutter blades for straw grinding, the straw grinder further reduces the grinding length of the straws, and the average qualification rate of the ground straws with the lengths less than 5 cm is higher than 90 percent. The biaxial straw grinder has good performance and achieves the purpose of energy conservation.
Description
Technical field
The utility model relates to the agricultural tool technical field, specifically belongs to twin axle cross disk hob wheat rice straw cracker.
Background technology
Current, the stalk crasher that everybody knows mainly contains the facility of 2 kinds of forms: the 1) stalk crasher of supporting tractor; This kind facility are pulverizing of carrying out separately at the field stalk after results, and this kind technology is because increased by 1 field farming, and peasant's production cost improves, so still there is not large tracts of land to adopt at present.2) stalk crasher of supporting combine; This kind facility are the emphasis of researching and developing in the present stalk crasher.Carry out the stalk crasher of crushed stalk with utilization moving knife high speed rotating and represent type for its typical case; Domestic existing full feed type wheat and rice combine harvester straw outlet is less, problem appears stopping up with existing stalk crasher coupling, consumed power is big and the crushed stalk qualification rate is low etc. easily, so be badly in need of exploitation straw-returning rate height, consumed power is little and can better satisfy the straw crushing and field-returning machine tool that agrotechnique requires.Based on the recycling requirement of straw-returning, with efficient, energy-conservation be target, design and develop a twin axle cross disk hob wheat rice straw cracker that is suitable for the full feed type combine.
The utility model content
The utility model provides a kind of twin axle cross disk hob wheat rice straw cracker, by having adopted twin axle cross disk hob group rotational shear stalk mechanism, carry out crushed stalk with moving knife high speed rotating and stationary knife cooperation, further reduce crushed stalk length, less than the crushed stalk average qualification rate of 5cm length all greater than 90%, the twin axle stalk crasher is functional, and has reached energy-conservation target.
The technical scheme that the utility model adopted is:
Twin axle cross disk hob wheat rice straw cracker, include mainframe, be rotatablely equipped with driving shaft, driven shaft on the mainframe, one end of driving shaft is equipped with belt pulley, the other end is equipped with driving gear, driven gear with the driving gear engaged transmission is installed on the driven shaft, is separately installed with the cross disk hob sheets that many groups cooperatively interact on described driving shaft, the driven shaft, be fixed with the ledger-plate that is involutory with cross disk hob sheet on the inwall of mainframe bottom.
Be equipped with on the described driven shaft and prevent twining dish, holding the strain cutterhead.
Described driving shaft, driven shaft are installed in the mainframe by self-aligning bearing respectively.
Be set with spacer on described driving shaft, the driven shaft, spacer is installed with cross disk hob sheet outward.
The utility model is by having adopted twin axle cross disk hob group rotational shear stalk mechanism, carry out crushed stalk with moving knife high speed rotating and stationary knife cooperation, further reduce crushed stalk length, less than the crushed stalk average qualification rate of 5cm length all greater than 90%, the twin axle stalk crasher is functional, and has reached energy-conservation target.
The utility model is installed in the combine straw outlet, is used for the stalk of discharging after the threshing shredded interrupting, and sheds that to carry out stalk in the field recycling.During work, the driving shaft of stalk crasher links to each other with the combine power take-off by belt pulley, driving shaft produces relative motion by gear drive and driven shaft, drives diaxon disk hob cutter group high speed rotary, cooperates with moving knife high speed rotating and stationary knife and carries out crushed stalk.
Compared with the prior art, the advantage that the utility model had is as follows:
1, adopts twin shaft cross cylinder blade to carry out the mode of crushed stalk,, improved the efficient of crushed stalk, reduced the power of crushing straw based on shearing the stalk working mechanism.
2, use gear transmission mode, increased the reliability and stability of driving and driven cutter shaft transmission.During design, can be according to the demand of practical production of diaxon rotating ratio, select suitable gearratio by gear changing more.
3, self-aligning bearing is adopted in the installation between master and slave moving axis and the mainframe, can allow big coaxiality error to a certain extent, cuts down finished cost, and is convenient for assembly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an end view of the present utility model.
Embodiment
Referring to accompanying drawing, twin axle cross disk hob wheat rice straw cracker, include mainframe 1, be rotatablely equipped with driving shaft 3 on the mainframe 1, driven shaft 12, driving shaft, driven shaft is installed in the mainframe by self-aligning bearing 5 respectively, self-aligning bearing is installed in the bearing block 10, one end of driving shaft is equipped with belt pulley 2, the other end is equipped with driving gear 8, driven gear 9 with the driving gear engaged transmission is installed on the driven shaft, driving shaft, be separately installed with the cross disk hob sheet 4 that many groups cooperatively interact on the driven shaft, driving shaft, be set with spacer 7 on the driven shaft, spacer is installed with cross disk hob sheet outward, is fixed with the ledger-plate 6 that is involutory with cross disk hob sheet on the inwall of mainframe bottom, and the anti-dish 11 that twines is installed on the driven shaft, hold strain cutterhead 14.
