Description

Returned straw pick-up fine crusher
Technical field
The utility model provides a kind of returned straw pick-up fine crusher, belongs to agricultural machinery technological field.
Background technology
The core of protective farming technique is to have a certain amount of crop cover or stalk to cover under the situation on the face of land, carry out no-tillage, minimal till sowing, the facility task difficulty is big, traditional sower generally can't carry out normal operation.Particularly in the Yellow River and Huai He River Haiti district, no matter be manually or machine combining autumn corn, generally all require to carry out straw-returning, with combined harvester with stubble cleaner or after tractor band rotovator carries out straw-returning, the length of maize straw is generally more than 6 centimetres, cause the trafficability characteristic of no-tillage wheat seeder relatively poor, easily caused to stop up and block up, influenced operation quality and operating efficiency.Many places are for stalk in small, broken bits, prior to seeding with rotovator with straw-returning plot rotary tillage two to three times, with the secondary crushing straw, create good sowing condition.But be not suitable for crushing straw because rotovator revolves the design and the distribution of cutter,, not only wasted manpower and materials, also aggravated disturbance surface soil layer by the poor effect that cutting face of land stalk comes stalk in small, broken bits.
The utility model content
The purpose of this utility model provides and a kind ofly can address the above problem, with below the crushed stalk to 1 centimetre, guarantee the returned straw pick-up fine crusher that no-tillage seeding carries out smoothly.Its technical scheme is:
Comprise the suspension pull bar, gearbox, frame, the pickup case, pickup and one-level driving belt, wherein gearbox is installed on the frame, the pickup case is suspended on the bottom of frame, the pickup bearings is installed on the frame, and be positioned at the below of pickup case, power take-off through one-level driving belt and gearbox is in transmission connection, it is characterized in that: set up the crushed stalk wheel at the pickup rear, the crushed stalk wheel bearing supports and is installed on the frame, the crushing wheel case is positioned at the back upper place of crushed stalk wheel, hanger bar through being set with the compression spring is hung on the hanger bracket of frame, the crushed stalk wheel is in transmission connection through the secondary driving belt with pickup, on the wheel rim of crushed stalk wheel, along the circumferential direction be interval with many row's flail knives, corresponding with it, along the circumferential direction be provided with the cutter blade that is ranked more on the crushing wheel case, arrange flail knife more and be spaced more, and both ends be overlapping diametrically with the cutter blade that is ranked.
Described returned straw pick-up fine crusher, the blade indentation of stationary knife blade.
Its operation principle is: provide power by tractor motive power output shaft by the gearbox that shaft coupling drives on the fine crusher, by being with flexible pickup the long stalk in ground is picked up, through pickup case feeding crushed stalk wheel, by the paired stalk of stationary knife blade shaped on flail knife and the crushing wheel case support cutting and grinding are arranged, under the high speed rotating cutting of crushed stalk wheel, long stalk secondary on the ground is ground into length less than 1 centimetre short straw-returning.
The utility model compared with prior art, its advantage is:
1, the utility model has designed with pickup and has picked up face of land stalk, adopts the flail knife of high speed rotating to cooperate the support that forms stalk is arranged to cut with the stationary knife blade, with on the ground long stalk secondary be ground into length less than 1 centimetre short stalk after and the field, effectively solve the technical barrier and the extensive problem of going back seeding quality difference under the situation of field of stalk of the supporting no-tillage seeding machine trafficability characteristic of middle-size and small-size power difference, and power consumption is low, and the amount of breaking ground is few;
2, the hanger bar of crushing wheel case through being set with the compression spring is hung on the hanger bracket of frame, can realize the automatic adjusting of the stationary knife blade radial lap on flail knife and the crushing wheel case, effectively prevent when the stalk feed quantity is big obstruction between crushing wheel case and crushed stalk wheel and pulverized inhomogeneous situation.
