Superposition.As the speed of land transformation is constantly accelerated gradually to expand with scale of agricultural production, large-scale forage harvester demand
To persistently it increase.
Currently, internal feed cropper is middle-size and small-size machine, and feed feed quantity is small, and efficiency of crop is low, insufficiency, feeds
Enter device and mainly use belt or chain drive, chopping length generallys use the adjusting of change gear box mechanical type manual.Large size is raised
Material cropper is occupied by foreign countries, and external cropper feeding unit generallys use belt transmission, and feeding blocks in order to prevent, if
It is equipped with dedicated block clearing reversion and antioverloading protection mechanism.In practical livestock breed aquatics, inhomogeneity livestock, similar livestock are different
Growth section feeding demand is also different, this just needs to realize feed the accurate chopping of various length.
Utility model content
The utility model aim is to propose a kind of stepless adjustable system of hydraulicdriven large-scale cropper feeding unit.
In order to achieve the above objectives, the utility model takes following technical scheme: a kind of large size cropper feeding unit is stepless
Adjustable system, have engine belt wheel, belt, two-way variable displacement plunger pump, pump belt wheel, sebific duct, two-way quantitative motor, controller,
Universal shaft, speed probe, main-gear box, stepless speed regulation mode be closed hydraulic loop, engine power through engine belt wheel,
Belt, pump belt wheel are transmitted to the two-way variable displacement plunger pump, and two-way variable displacement plunger pump hydraulic fluid port and two-way quantitative motor hydraulic fluid port pass through two
The connection of root sebific duct；The two-way quantitative motor is connect by universal shaft with main-gear box；The speed probe real-time monitoring ten thousand
To axis revolving speed and feed back to controller, controller control two-way variable displacement plunger pump discharge capacity output size or stop output, when
When revolving speed and rotating speed of target deviate, controller changes two-way variable displacement plunger pump discharge capacity, meets feeding speed requirement.
Two-way variable displacement plunger pump drives feeding unit to realize feeding in terms of shaft end when revolution clockwise, and when turning anticlockwise is used
In removing feeding unit putty, the variation of chopping length within a certain range can be realized by changing discharge capacity.It is controlled by controller, it is double
Quickly it can export or stop to variable piston pump discharge, to reach the quick start of two-way quantitative motor and feeding unit or stop
Only operate.
Further, it is provided with tensioning wheel with what belt cooperated, prevents belt transmission slip.
Main-gear box is connected with dancer, upper pony press, and main-gear box is also intermeshed simultaneously with pinion case with gear
Connection, pinion case are connected with lower pony press, fixing roller, and material is constituted between upper pony press and lower pony press and feeds channel.
For the utility model the utility model has the advantages that first is that feeding unit is driven using closed type hydraulic system, Speed rigidity is good, guarantees
The stability of transmission revolving speed, the another control mode for using electro-hydraulic combination form closed-loop control by speed probe, convenient to feed
Enter the step-less adjustment of speed, it is ensured that shred the accurate adjusting of length；Second is that structure flexible arrangement, Yi Shixian overload protection, anti-
Turn can rapid block-cleaning, increase maintenanceability, the reliability and safety of system.
Detailed description of the invention
Fig. 1 is the utility model drive path schematic diagram；
It is attached in the figure, it is marked as 1- engine belt wheel, 2- belt, 3- tensioning wheel, 4- two-way variable displacement plunger pump, 5- pump belt wheel,
6- sebific duct, 7- two-way quantitative motor, 8- controller, 9- universal shaft, 10- speed probe, 11- main-gear box, 12- dancer,
Pony press, 15- pinion case, 16- fixing roller under the upper pony press of 13-, 14-.
Specific embodiment
In order to be more clear the purpose of this utility model, technical solution, with reference to the accompanying drawing to the utility model compared with
Good embodiment is described in detail, but is not intended as the limitation foundation of the utility model.
See Fig. 1, the present embodiment have engine belt wheel 1, belt 2, tensioning wheel 3, two-way variable displacement plunger pump 4, pump belt wheel 5,
Sebific duct 6, two-way quantitative motor 7, controller 8, universal shaft 9, speed probe 10, main-gear box 11.The bidirectional variable plunger
The power input of pump 4 derives from engine belt wheel 1 and belt 2, and two-way quantitative motor 7 is connected by universal shaft 9 and main-gear box 11
It connects, the use of universal shaft 9 makes flexible for installation convenient for structure arrangement.The revolving speed of 10 real-time monitoring universal shaft 9 of speed probe is simultaneously anti-
It feeds controller 8.Main-gear box 11 is connected with dancer 12, upper pony press 13, main-gear box 11 simultaneously also with pinion case 15
It is intermeshed and is connected with gear, pinion case 15 is connected with lower pony press 14, fixing roller 16, upper pony press 13 and lower pony press 14
Between constitute material feed channel.
The stepless adjustable mode uses hydraulic closed drive circuit, and the pump belt wheel 5 of two-way variable displacement plunger pump 4 passes through engine
Belt wheel 1 drags, and belt 2 also drags cropper other function component, and belt 2 skids in order to prevent, and being provided with can apply centainly in advance
The tensioning wheel 3 of clamp force.In harvest, usual engine speed is constant a certain value, controller 8 can preset signals control it is two-way
4 displacement size of Variable plunger pump and oil circuit direction change two-way variable displacement plunger pump 4 since two-way quantitative motor 7 is fixed displacement motor
9 revolving speed of universal shaft is adjusted in discharge capacity, is finally reached the variation of feeding unit rate of feeding, realizes chopping length in a certain demand model
Enclose interior step-less adjustment.When feed quantity is excessive, the advantages of closed hydraulic loop utilizes itself, can high pressure kicks, it is automatic to realize
Feeding unit overload protection.Often overload easily causes the putty of feeding unit, and controller 8 can control two-way variable displacement plunger pump at this time
The change in 4 oil circuit directions, lower velocity interpolation safety automation block clearing.When universal shaft 9 rotates, 10 real-time monitoring of speed probe
Its revolving speed is simultaneously transferred to controller 8, and when offspeed goal-selling revolving speed, controller 8 controls 4 discharge capacity of two-way variable displacement plunger pump
Change, to ensure invariablenes turning speed, the final accurate adjusting for realizing chopping length.
