Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a flexible weeding device used on a strip tiller. Background Art

[0002] Strip tillage, a key technology within conservation tillage, boasts high efficiency and excellent crop emergence. The primary process of a strip tiller is straw removal, which involves clearing a strip suitable for seeding on a plot of land where all straw has been returned. Straw removal directly impacts corn yield. When straw remains in the strip, corn seeds can fall onto the stalks, impacting seed emergence. The weed wheel, the primary component of the strip tiller for straw removal, is crucial to its overall effectiveness.

[0003] Currently available weed-pulling wheels mainly include spoke-type and disc-type. Spoke-type weed-pulling wheels take up a lot of space and are ineffective at cleaning finely chopped straw, while disc-type weed-pulling wheels tend to throw soil into the straw belt and are not ideal for cleaning straw in ditches.

[0006] According to a flexible weed-picking device of the present application, bearing seats are respectively provided on both sides of the adjustment hole plate, and a weed-picking wheel is respectively provided on the bearing seats on both sides connected through a first cover plate and a second cover plate.

[0007] Furthermore, the surface angle between the bearing seats and the grass-moving wheels installed on both sides of the adjustment hole plate is thirty degrees.

[0008] Preferably, a retaining ring for limiting the position of the inner end of the wire rope is further provided inside the grass wheel unit formed by the first cover plate and the second cover plate, and the retaining ring is connected to the inner surface of the first cover plate or the second cover plate.

[0009] Preferably, the outer edges of the first fixing sleeve and the second fixing sleeve are respectively provided with a plurality of semicircular grooves. When the first cover plate and the second cover plate are arranged opposite to each other and connected, the semicircular grooves on the first fixing sleeve and the second fixing sleeve are correspondingly closed to form circular holes for inserting and clamping the wire rope.

[0010] Preferably, a reinforcing plate is provided between the horizontal beam and the vertical beam, the top of the reinforcing plate is fixedly connected to the horizontal beam, and the side of the reinforcing plate is fixedly connected to the vertical beam.

[0011] Furthermore, the bearing seat includes an inner ring portion and an outer ring portion that can rotate relative to each other; the inner ring portion is connected to the adjustment hole plate, and the outer ring portion is connected to the first cover plate and the second cover plate; or, the outer ring portion is connected to the adjustment hole plate, and the inner ring portion is connected to the first cover plate and the second cover plate.

[0012] After adopting the technology proposed by the present invention, the flexible weed-pulling device according to the embodiment of the present invention has the following beneficial effects.

[0013] The grass-moving wheel's soil-touching end is a steel wire rope with a large contact area with the straw. It can move the straw and sweep away the straw, effectively improving the cleaning effect of fine straw.

[0014] The grass-moving wheel's contact end is flexible and can change its contact angle according to terrain changes, thereby improving the cleaning ability of ditches and trenches.

[0015] The end of the weed-removing wheel that touches the soil is a steel wire rope. The spacing between the steel wires is too large to form a closed space. At the same time, the steel wires will deform when subjected to force, avoiding pushing soil to both sides, thereby reducing the amount of soil thrown into the straw belt.

The retaining ring 11 is connected to the inner surface of the first cover plate 7 or the second cover plate 8.

[0025] The outer edges of the first fixing sleeve 9 and the second fixing sleeve 10 are respectively provided with a plurality of semicircular grooves. When the first cover plate 7 and the second cover plate 8 are arranged opposite to each other and connected, the semicircular grooves on the first fixing sleeve 9 and the second fixing sleeve 10 are correspondingly closed to form circular holes for inserting and clamping the wire rope 6.

[0026] The first cover plate 7 and the second cover plate 8 are mounted on the bearing seat 5 so as to be rotatable relative to each other.

[0027] The regulating hole plate 4 is provided with a bearing seat 5 on both sides, and a grass-moving wheel is connected to the bearing seats 5 on both sides through a first cover plate 7 and a second cover plate 8.
