Abstract
The utility model relates to a seeding apparatus of agriculture seed drills, in particular to a cell wheel type seeding apparatus. The utility model is composed of a cell wheel equipped in the casing through a square shaft, a scrape seed component against on the peripheral wall of the cell wheel, a protecting seed component and a picking seed slice. The utility model is characterized in that the protecting seed component comprises a rigid cambered protecting seed plate, a torsional spring and a pin shaft fixedly equipped on the inner wall of the casing. The upper end hole of the protecting seed plate is sleeved on the pin shaft by movable fit. The torsional spring is equipped on the outer wall of the protecting seed plate through the pin shaft and makes the lower part of the protecting seed plate abut tightly on the peripheral wall of the cell wheel. The improved cell wheel type seeding apparatus has the advantages of longer life time, higher reliability and higher stability and it can effectively enhance the work efficiency and decrease use cost.
Description
Technical field
The utility model relates to the seeding unit in the agricultural seeding machine, particularly a kind of nest eye Type Seed Metering Device.
Background technology
Scraping kind in the present nest eye Type Seed Metering Device, protect kind of parts, adopt the rubber parts of rapid wear or hairbrush spare to make mostly, in the seeding process, very easily damage and the reliability and stability of work relatively poor.Therefore, need often change or adjust these parts, influence operating efficiency, increase maintenance cost.
Summary of the invention
The purpose of this utility model is for solving the above-mentioned shortcoming that present nest eye Type Seed Metering Device exists, proposing a kind of improved nest eye Type Seed Metering Device, to improve its service life and reliability, stability.
The utility model is by being arranged on the nest eye wheel in the housing by square shaft and being resisted against scraping kind of parts, protect kind of parts and pick kind of a sheet and form on the nest eye wheel perisporium, it is characterized in that described kind of the parts that protect comprise a rigidity arcuate seed protecting plate and torsionspring, bearing pin, bearing pin is installed on the madial wall of housing, the upper end hole of seeds protecting plate is being nested with on bearing pin movingly, torsionspring also is arranged on the outer wall of seeds protecting plate by bearing pin, and its underpart is pushed against on the perisporium of nest eye wheel.
This improved nest eye Type Seed Metering Device has higher service life, reliability and stability, improves its operating efficiency effectively and reduces use cost.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
