Description
Technical field
The utility model relates to field of agricultural machinery, and in particular to a kind of full dose of achievable stalk automatic shunt regulation
Stalk ground wheat seeder.
Background technique
Full dose stalk wheat seeder can once complete straw powder in the case where preceding stubble stalk is without any processing
It is broken, cleaning throw, rotary tillage sowing, improving straw mulching, for straw-returning Fertilizer Transformed utilize, realize prohibit burning providing powerful support.So
And when preceding stubble is the big crop of the stalks amount such as rice, corn, excessive improving straw mulching will cause wheat be short of seedling, weak seedling situation,
And then influence yield.
The patent No. 201410113918.7 " one kind covers the adjustable full straw covering plot no-tillage wheat seeder of straw amount " is open
A kind of full dose stalk of adjustable overlay capacity ground no-tillage wheat seeder, may be implemented that part stalk buries, part stalk covers
Lid, and the stalk amount of burying and coating ratio are adjustable, but it has the following problems in practical applications:
1, the stalk that the technology is crushed by adjustable plate arresting portion enters horizontal screw feeder, remaining stalk is from adjustable plate and horizontal
It sets and enters horizontal screw feeder in the crack between screw feeder casing, for a long time in the big field operation of stalk amount, adjustable plate is stirred with horizontal
Crack between imperial shell is easy blocking stalk, causes equipment failure.
2, different field stalk amounts have differences, this just needs machine hand deep to the insertion of adjustable plate when replacing field operation
Degree is adjusted, time-consuming and laborious, and before machine manual task again be difficult to judge field straw amount number, thus regulated quantity can not shift to an earlier date
It determines.
3, in a certain field operation, the distribution density of field straw also tends to unevenness, and the technology can only be according to operation
Before the ratio that sets stalk is shunted, cause improving straw mulching uniformity bad, be unable to give full play the function of improving straw mulching sowing
Effect.
4, the insertion depth of adjustable plate is changed by limited screw hole, and degree of regulation is poor.
In rice-wheat, corn-wheat crop rotation area answer with affecting full dose stalk by wheat seeder for the above problem
With this field has wished to overcome above-mentioned insufficient technical solution.
Utility model content
The utility model is in view of the above-mentioned problems, propose that a kind of stalk of suitable for full dose stalk wheat seeder divides automatically
