Description
Technical field
Patent of the present invention belongs to agricultural mechanical field, specially a kind of silage harvester automatic knife-grinding apparatus, is applicable in
It is matched with silage harvester cylinder type cutterhead.
Technical background
With the rapid development of animal husbandry and the adjustment of corn planting structure, corn silage harvest or fruit ear stalk are taken in concurrently
Stalk cutting is rapidly developed, therefore corn harvester for silage is widely used.But reach a certain amount of when machine acts on, stalk
Moving knife blade on the chopping hobboing cutter of shredding mechanism will appear different degrees of abrasion, cause cutting quality poor, and consumption power is big,
It whets a knife.It is more moving knife due to having on the chopping hobboing cutter of straw chopping apparatus, if by moving knife slices sharpening, not only imitate
Rate is low, is also difficult to ensure that the dynamic balancing of chopping hobboing cutter.
Currently, there are mating automatic grinding system or manual knife sharpening device on external silage harvester, whetted a knife manually than certainly
Dynamic sharpening efficiency is low, and domestic part type has mating manual knife sharpening device, and service efficiency is relatively low.External silage harvester it is automatic
Sharpening system structure and control system complexity, cost are very high.Therefore domestic ensiling harvester for maize or corncob and stalk corn harvest
Machine is badly in need of a nested structure and the simple knife sharpening device of automatic control system.
Invention content
The purpose of the present invention is to solve the above problems, provide a kind of structure and the simple ensiling of automatic control system is raised
Expect cropper automatic knife-grinding apparatus.Its technical solution is：
A kind of silage harvester automatic knife-grinding apparatus, it is characterised in that：Including reciprocating mechanism and feeding of whetting a knife
Mechanism；Wherein reciprocating mechanism includes guide rail base, two guide rails being horizontally arranged on guide rail base, is led mounted on two
Pairs of sliding block on rail, the slider plate that the fixation of pairs of sliding block is connected as a single entity, leading screw, leading screw bearing, feed screw nut, motor and
Pawl, one end of leading screw are mounted on by leading screw bearing on guide rail base, and the other end passes through shaft coupling and the output terminal of motor
It is connected, feed screw nut is mounted on leading screw, and feed screw nut is fixedly mounted on slider plate towards on the side wall of guide rail, and pawl is mounted on
On guide rail base, positioned at one end of guide rail；The blade grinder of sharpening feed mechanism including bowl-type, sharpening housing, worm gear, worm screw,
Axis, feeding set, ratchet, handwheel, bearing and key, down suction passes through feeding to cover to axis from bottom to top, and axis is pierced by feeding set
A ratchet is fixed in upper end, and the bottom of axis is fixedly connected with blade grinder；Feeding set is sleeved on by upper and lower two bearings on axis, is fed
Multiple keyways are evenly equipped on the outer wall of set upper side in an axial direction, corresponding with multiple keyways, the inner wall of worm gear is equipped with multiple keys, worm gear
It puts on, can slide up and down along keyway mounted in feeding with keyway engagement sleeves through key；The outer wall of feeding set lower end is equipped with screw thread, whets a knife
Housing is sleeved on feeding set and worm screw, and the lower end of sharpening inner walls is connect with feeding external threading, and handwheel is fixedly mounted on snail
Bar is pierced by one end of sharpening housing, and handwheel is along the circumferential direction equipped with scale；The upper end of sharpening housing is equipped with end cap, sharpening housing
Side wall is fixedly connected with slider plate.
Operation principle is：
Before sharpening, the ceding of Taiwan and feeding component that make ensilage machine shut down completely, and sharpening feed mechanism is pushed into shred
Among roller, slowly rotation hand wheel, handwheel driving worm screw, worm screw drive worm gear, so as to make the opposite sharpening housing into rotation of feeding set,
Since parts are threadedly coupled, feeding set is driven to move down, and then blade grinder and blade contact, starts motor and blueness
The chopping cylinder of storage machine；During sharpening, roller forward direction low speed rotation, blade grinder is driven under the driving of motor by feed screw nut
It moves reciprocatingly, and so as to which the cutting edge of moving knife on roller is ground a cylindrical surface again, after having ground knife, knife grinding mechanism is moved to rolling
The side of cylinder is whetted a knife and is completed；When next time whets a knife, rotation hand wheel certain angle, driving feeding set moves down given sharpening amount, then
Start the chopping cylinder of motor and ensilage machine.
Compared with prior art, the present invention it the advantage is that：
1st, there is the kind of drive of auto-lock function using worm gear, worm screw, i.e., only rotary worm could drive worm gear to rotate,
Otherwise the mode that worm gear cannot rotate can be such that blade grinder is located at this feeding after each whet a knife, so as to make next time into
It is determined to benchmark, worm gear, worm screw also accurately control the amount of feeding of blade grinder, and it is inadequate to be unlikely to the amount of feeding, is not achieved and wants
The effect asked also is unlikely to the excessive service life for reducing hobboing cutter of the amount of feeding；
2nd, ratchet and pawl cooperation, which makes blade grinder often do primary move back and forth, to rotate a certain angle, so as to control
Blade grinder Even Grinding, does not generate gully；
3rd, to improve sharpening efficiency, it is proposed that a kind of on-line automatic knife sharpening device for not having to dismounting, and its is simple in structure easily
The dynamic balancing of hobboing cutter is automatically controlled and ensures in realization.
