Description

Metal sawtooth film opener

Technical Field

The invention relates to a hand-push type seeder, in particular to a metal sawtooth film opener used on the hand-push type seeder.

Background

Because economic development, agricultural mechanization degree is higher and higher, because the seeder can replace traditional manual operation, has characteristics such as efficient, convenient to carry, the demand of seeder is also higher and higher. The current hand propelled disseminator equipartition is equipped with the kind hole, and the bottom of seed case is arranged in at the top of taking the race, and the seed falls in kind hole under the effect of gravity, and this disseminator is efficient, convenient to carry, but only is fit for ordinary field use, still need cooperate traditional manual hand dyestripping when sowing in the farmland of having the plastic film paved, manual hand dyestripping not only useless worker, waste force, the side branch influence output that still scratch peanut seedling easily! The cover of the closed herbicide applied to the crops under the film is easy to damage, and the seedlings of the later-period crops are easy to weed. If the mulching film on the seeds is not torn off in time after seedlings of crops such as peanuts emerge, the crops are easy to roast seedlings at high temperature under the mulching film, and the symptoms such as herbicide hazard are easy to appear! This therefore severely limited the development of the seeder.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a membrane ware is driven to metal sawtooth should drive the membrane ware and install at hand propelled disseminator duckbilled root, can be accurate the plastic film on the crop seed prick a little aperture all around, need not artifical dyestripping, labour saving and time saving does benefit to the crop growth.

In order to solve the problems existing in the prior art, the utility model discloses a technical scheme be:

the metal sawtooth film opener is installed and is used on hand propelled disseminator, including base and cutter, the base on evenly be provided with a plurality of screw, the base passes through the screw and the screw is fixed on hand propelled disseminator's casing, the lower extreme of cutter is fixed on the base, the cutting edge department of cutter is provided with at least one decurrent concave tooth, the cutter is installed around the duckbilled, both contactless, the height that highly is higher than the cutter of duckbilled.

Further, the base is circular.

Further, the height of the duckbill is three times of the height of the cutter.

Furthermore, four downward concave teeth are uniformly arranged at the blade of the cutter.

Further, the cutter be cylinder, prismatic, cuboid or the square structure that link up from top to bottom, the duckbilled is located the cutter. The maximum distance d between the bottommost end of the duckbill and the knife is 1.5 cm.

Furthermore, the knife is a columnar structure with a U-shaped cross section, and the duckbill is positioned in the knife.

Further, the knife is a sheet structure, and the duckbill is positioned on one side of the knife.

The utility model has the advantages and beneficial effects that:

the utility model relates to a metal sawtooth bursts at membrane ware and installs and use on hand propelled disseminator, because the periphery at the duckbilled is provided with the cutter, the cutting edge department of cutter is provided with a plurality of decurrent concave teeth. After hand propelled disseminator duckbilled root installation metal sawtooth membrane opener, use this disseminator when crops such as maize, soybean, peanut, chinese-medicinal material are sowed to the plastic film, consequently, some apertures are pricked all around to the plastic film that consequently the membrane opener can be accurate on the crop seed, and because the bottom of duckbilled is 1.5cm with the maximum distance d of cutter, the cutting edge department of cutter evenly is provided with decurrent concave tooth, the distance of these apertures and aperture and seed is favorable to the seed to breathe freely, sprout fast, be favorable to the seedling to be strong the seedling neat. When seedlings of crops such as peanuts and the like come out of the soil, the seedlings can burst the mulching film which is opened by the sawtooth film opener, so that the defects that the conventional film is torn by hands only manually are avoided.
