Embodiment Construction
[0012] Such as figure 1 As shown, the bulldozing device for seeding and fertilizing drums includes a hole seeding nozzle 4 fixed on the drum, a V-shaped cover device, and a cover spring located between the V-shaped cover operating arm part 7 and the outer ring of the drum 5 6. The V-shaped cover device includes a V-shaped cover operating arm part 7 and a cover part 2. The bottom of the V-shaped cover device is hinged at the root of the hole-seeding nozzle 4, and the cover part 2 usually covers the hole-seeding nozzle 4 tightly. It also includes a bulldozing device; the bulldozing device includes a positioning device 1 and a bulldozing tongue 3, the positioning device 1 is located in the middle of the V-shaped cover plate operating arm part 7, and one end of the bulldozing tongue 3 is connected to the positioning device 1 Fixed, the other end walks around the bottom of the V-shaped cover plate device and slides in contact with the upper jaw in the hole sowing mouth 4.

The invention provides a hole sowing nozzle bulldozing device for a sowing and fertilizer-applying roller, belongs to the technical field of agricultural machinery, and mainly solves the problem that in the prior art, soil is easily attached to the hole sowing nozzle in the working process, so that a cover plate of the hole sowing nozzle can not cover tightly, consequently, the phenomena of seed leakage and fertilizer leakage are caused, and finally the precision of hole sowing is affected. The device comprises the hole sowing nozzle fixed on the roller, a V-shaped cover plate device and a cover plate spring located between a V-shaped cover plate operating arm part and an outer ring of the roller, wherein the V-shaped cover plate device comprises an operating arm part and a cover plate part, the bottom of the V-shaped cover plate device is hinged with the root of the hole sowing nozzle and the cover plate part covers the hole sowing nozzle tightly in ordinary time. The device is characterized by further comprising a bulldozing device which comprises a positioning device and a bulldozing tongue, wherein the positioning device is located in the middle of the V-shaped cover plate operating arm part and one end of the bulldozing tongue is fixed with the positioning device while the other end is slidingly contacted with the palate of the hole sowing nozzle by coming around the bottom of the V-shaped cover plate.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bulldozing device with hole sowing nozzles for sowing and fertilizing drums. Background technique [0002] Generally, hole application can make more concentrated use of fertilizer than strip application and spreading application, and it is also more economical. Usually, soil is covered after fertilization in holes. In order to avoid damage to the root system of crops by high-concentration fertilizers in holes, the organic fertilizer (or bio-organic fertilizer) used in hole application must be fully decomposed in advance, and the amount of chemical fertilizers must be appropriate, which can effectively prevent crop roots from being burned by fertilizers. The large-scale demonstration and promotion of Shanxi University for many years has proved that increasing the application of bio-organic fertilizers is an effective means to improve the yield and qual...
