Abstract
The present invention relates to a combination and inner hole type precise seed metering device used for precision seeding, which is composed of a casing, a seed metering wheel which is provided with a seed metering wheel shaft, and a seed metering square shaft which is sheathed in a square hole of a seed metering wheel shaft rod, wherein the seed metering wheel shaft rod is sheathed in a center hole of the casing and is locked by a regulating nut; the seed metering wheel shaft rod forms sliding fit with the center hole of the casing; the side wall of the casing is provided with a seed inlet which is communicated with a seed groove; the cylinder surface of the casing is also provided with a seed charge opening; the inner side surface of the seed charge opening of the casing and the cylinder surface are respectively provided with a lateral and radial seed unloading groove; column-shaped filling holes and inner holes are distributed on the outer margin of the seed metering wheel in equidistance; the inner holes are connected with the filling holes. The present invention is characterized in that the present invention is also provided with a spring which can be used for adjusting the axial relative position between the seed metering wheel and the casing. The width dimension of a quantitative hole of each of the inner holes can be changed by adjusting the axial gap between the seed metering wheel and the casing; consequently, big-grain corn seeds can be simultaneously sown when small-grain soybean seeds are sown in a precision seeding mode under the condition that the seed metering wheel is not replaced.
Description
Technical field
The present invention relates to agricultural seeder machinery, be specifically related to a kind of mechanical precise seeding unit that is used for precise sowing.This seeding unit is particularly suitable for the precise sowing of large seeds such as corn, soybean.
Background technology
Precise sowing has the saving seed, reduces field thinning final singling recruitment, improves crop yield and reduces the production of hybrid seeds with advantages such as fields, is the only way which must be passed of agricultural modernization, also is to reduce grain-production cost and one of important measures of increasing farmers' income.In developed country, carry out precise sowing already as crops such as corn, soybean, beets.
The key that realizes precise sowing is the heart of sower---seeding unit can satisfy the Precision Seeding requirement.China's precise sowing that begins one's study from the seventies fails to be widely used so far, and wherein reason is a lot, and mainly being does not have the seeding unit that is suitable for.
The external used seeding unit of Precision Seeding mostly is pneumatic type, and this seeding unit structure is complicated, price is high, and working service requires tight.And hole roller formula machinery seeding unit, simple in structure, price is low, working service is convenient, reliable operation, Chinese scholars generally believes that this seeding unit is to broadcast large seed, as comparatively ideal seeding units such as corn, soybean, but exist the strictness of shape of the seed dimensional requirement, the seed damage ratio is high and be not suitable for shortcoming such as high speed operation.
The applicant's the ZL97122327.0 of patent of invention formerly " precision seeder for maize ", it is a kind of compound type hole filling seed inside precision seeder, adopt the operation principle of filling seed inside and gravity seed cleaning, the seed damage ratio is low, be suitable for the high speed operation, when adopting the stairstepping inner hole, can adapt to the seed of difformity and size to a certain extent, but also exist shortcomings such as stairstepping inner hole complex manufacturing technology and shape of the seed size accommodation is narrow.
Summary of the invention
The objective of the invention is shortcomings such as the shape of the seed size accommodation that exists at the compound type of the applicant's patent of invention ZL97122327.0 hole filling seed inside precision seeder is narrow and do further structural improvement, and propose a kind of combination inner hole precision seeder that improves structure.
In order to make a seeding unit can adapt to the more shape of the seed and the size of wide region, make adjustable dosing hole best choice often.And compound type hole filling seed inside precision seeder is formed interior nest dosing hole jointly by inner hole on the seed wheel and housing sidewall, thereby by changing the axial location of seed wheel with respect to housing, promptly adjust end play between the two, the width dimensions of nest dosing hole in can changing.By test also as can be known, interior nest dosing hole width dimensions is bigger to the Precision Seeding performance impact of this seeding unit.
The present invention realizes by following scheme:
Combination inner hole precision seeder is by housing, be provided with the seed wheel of seed wheel axostylus axostyle, be sleeved on the seeding square shaft in the seed wheel axostylus axostyle square hole, the interior seeds protecting plate that is installed on the housing madial wall is formed, the seed wheel axostylus axostyle is sleeved in the centre bore of housing and by adjusting the nut locking, seed wheel axostylus axostyle and housing centre bore are and are slidingly matched, have on the sidewall of housing and plant the seed inlet that case communicates, also have the mouth of charging seed on the face of cylinder of housing, on housing is charged seed mouthful the medial surface at place and inner cylinder face, have side direction and radially unload kind of a groove, equidistantly be distributed with cylindricality pack hole and the inner hole that links to each other with pack hole on the seed wheel outer rim, its characteristics are also to be provided with the spring that can adjust relative axial position between seed wheel and the housing; Described inner hole has the tilting sidewall.
The present invention has the following advantages:
1. because this seeding unit is adjusted nut by rotation spring is elongated or shortened, thereby realize that axial gap is (as common 0.5～1mm) between adjustment seed wheel and housing, the width dimensions of nest dosing hole in can changing, thereby just can make this seeding unit can adapt to wideer shape of the seed and size range.This seeding unit can be under the situation of not changing seed wheel the big grain of Precision Seeding simultaneously corn seed (long flat or round shaped grain) and than the soya seeds of granule;
2. the stepped side walls inner hole is changed over the sloped sidewall inner hole, significantly reduced the manufacture difficulty of inner hole.
