Description
Technical field
The utility model is related to agricultural mechanical fields, and in particular to a kind of weeder of corn wheat no-tillage seeding machine.
Background technology
To return crop stocks to the field covering and few protective farming technique of the no-tillage seeding as main technical content is world today's agriculture
The trend of industry development.And protective farming technique is fully established on the basis of mechanization of agriculture, as stalk crushing, farmland are deep
The key operations such as pine, no-tillage seeding can only be completed by machine.No-tillage seeding machine refers to cover in crop material straight on the ground
The machine of row sowing and fertilising is tapped into, is the key equipment for implementing conservation tillage.But the covering stalk of earth's surface and root stubble meeting
Bigger difficulty is brought to no-tillage seeding, is especially harvested for one time each year and yields two crops a year area in northern China, the no-tillage seeding of wheat
Earth's surface maize straw residue mulching amount is big after being harvested due to front-wheel crop plants corn, and its root stubble is thick, toughness is strong, causes wheat no-tillage seeding
Machine, it is easy to appear blocking and influencing plough trench digging to sow, adds the research and development of light-duty no-tillage seeding machine in operation process
Difficulty.Cause the key points and difficulties that no-tillage seeding machine is conservation tillage equipment, not only need to have the performance of regular drill,
Also it can realize no-tillage seeding in the case where earth's surface has preceding crop root stubble or improving straw mulching.Therefore, its anti-heap soil or fertilizer over and around the roots is blocked up
Performance, bury trench digging performance, seeding fertilizer performance have very high requirement, so, using active anti-block apparatus be can not or
Scarce key technology.Main anti-blocking scheme has at present：1. power drive is anti-blocking, mainly by tractor output shaft band movable arbor rotary tillage
Stubble-cleaning, anti-blocking performance is good, there are the problem of be that the disturbance of upper earth is big, power consumption is big.2. non-power driven ultrasonic is anti-blocking, mainly round
Disk breaking is anti-blocking, and disk breaking effect is good, and equipment passability is good, but disk needs normal pressure big, each 180~200kg of disk,
It buries mainly by equipment gravity breaking, therefore equipment weight is big, it is expensive.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of weeder of corn wheat no-tillage seeding machine, with solution
The problem of certainly seeder prevents weeds straw harmony from blocking up, raising plough penetration performance.
To solve, the technical solution adopted in the utility model is：A kind of corn wheat no-tillage seeding
The weeder of machine including clip, tooth-shape disc, connecting rod, tension spring, and passes through clip in front of no-tillage seeding machine
Below rack, it is characterised in that：
The small end and the pin hinge on rear side of rack, connecting rod lower end is connected with bearing block；Connecting rod top
Support plate is installed, hole is machined on support plate；
The tooth-shape disc is fixed on bearing block, and tooth-shape disc is rotated using the bearing of bearing block as axis；
On the clip installation frame, column is installed below clip, column lower end is machined with hole；
Described tension spring one end is articulated in the hole of column lower end, and the other end is articulated in the hole of support plate.
Particularly, in order to further improve the performance that sowing machine-cut stubble is anti-blocking, ditches, the invention also discloses a kind of specific
Tooth-shape disc, the tooth-shape disc is preferably spill, and the tooth form at tooth-shape disc edge is zigzag, and straight cutting edge is towards advancing
Direction, spill plane are 15 °~25 ° towards direction of advance, and with the angle of direction of advance.
Generally, the concavity radius of tooth-shape disc can according to cut stubble, trench digging need to select it is suitably sized, particularly, this hair
Bright tooth-shape disc concavity radius is preferably 500~550mm, and depth is 20~30mm.
Generally, the toothed cutting edge cutting angle of tooth-shape disc can according to cut stubble, trench digging need to select it is suitably sized, especially
Ground, the toothed cutting edge cutting angle of tooth-shape disc of the present invention is preferably 20 °~30 °.
In order to adjust the pulling force of tension spring, the hole of 2 or more can be machined on support plate of the invention, the present invention is implemented
3 holes are machined on the specifically disclosed support plate of example.
Advantageous effect
The utility model provides a kind of weeder for no-tillage seeding machine, and stubble is anti-blocking, chopping straw is miscellaneous with cutting for the device
Grass, sliding cutting ability are strong, output neat kind ditch, is simple in structure, matching with various large, medium and small no-tillage seeding machines.Weeder
Seeder can be made to prevent weeds straw harmony from blocking up, improve plough penetration performance, and machine weight can be mitigated, reduction is manufactured into
This, significantly improves work efficiency.The weeder advantage of the corn wheat no-tillage seeding machine of the utility model is：
1. with the weeder wheat no-tillage planter can realize successively cut stubble it is anti-blocking, trench digging, seed manure sowing, earthing and
The multiple working procedures such as suppression.Wherein, anti-block apparatus uses serration type, and blade is designed as star serrated knife, has and is not easy to twine grass, sliding cutting energy
The characteristics of power is strong；
2. can effectively solve the problem that as stalk, weeds etc. to plough winding and caused by clogging, and pass through performance
Well, suitable for the no-tillage conservation tillage of the northern China corn wheat rotation of crops；
The crushing straw of front and weeds etc. can be shredded or pushed open by 3 weeders, it is ensured that double disk opener handle below
Seed is broadcast into soil, and mitigation discharging tube is contributed to stop up stifled and raising seed level uniformity.The device is small to soil disturbance, ensures to broadcast
Grading after kind machine sowing, emergence is uniform, and the anti-blocking ability of breaking is strong；
4. simple in structure, simple and convenient operation and maintenance can be matched with the seeder of large, medium and small various models.
