Description

Paddy field weed-killer is harrowed

Technical field

It the utility model is related to field of agricultural cultivation, and in particular to a kind of paddy field weed-killer rake.

Background technology

Substantial amounts of water plant can be grown in present paddy field, because the standing grain second in rice field is more, the weeds on ground are hidden by standing grain Firmly, people can cause if manual weeding, and the seedlings of cereal crops hinder eyes, and workload is big, it is not easy to remove totally, also artificial weeding It is most of not root out grass roots, it in the case of the fertilizer abundance of paddy field, may proceed to grow out, cause weeding unclean.

The content of the invention

For above-mentioned the shortcomings of the prior art, the utility model provides a kind of paddy field weed-killer rake, facilitates paddy field to remove Grass, weeding are clean.

To achieve the above object, the technical solution adopted in the utility model：Paddy field field weeding hoe, including harrow frame, rake knife, liter Screw rod drops, and harrow frame is made up of longitudinal rod and transverse bar, longitudinal rod welding orthogonal with transverse bar, and four through holes are provided with transverse bar, Inserted with lifting screw in each through hole；The first nut has been inserted at the top of lifting screw, the first nut is located above transverse bar, The second nut is inserted on the lifting screw below transverse bar, the bottom of lifting screw is fixed with rake knife, harrows the bottom of knife Tooth form knife is fixed with, the both sides for harrowing the bottom of knife are extended with two fix bars, and steel wire is wound between two fix bars.

Preferably, the concave surface for harrowing knife is cambered surface.It is easy to collect weeds.

Preferably, steel wire is located at before tooth form knife.First cut weeds root.

Compared with prior art, the utility model has the advantage of steel wire can be used for removing root depth below rake knife Weeds, tooth form rake knife are used to remove small-sized weeds, weeds are collected into together, and the lifting screw of setting is used for for rice The height of cross bar highly is adjusted, will not hurt the seedlings of cereal crops.

Brief description of the drawings

Fig. 1 is front view of the present utility model.

Fig. 2 is the partial view of the utility model cross bar.

Fig. 3 is the right view of rake knife of the present utility model.

Wherein, 1, harrow frame, 2, longitudinal rod, 3, transverse bar, 4, through hole, 5, rake knife, 6, tooth form knife, 7, fixed mount, 8, steel wire, 9th, lifting screw, the 10, first nut, the 11, second nut.

Embodiment

In conjunction with accompanying drawing, the utility model is further elaborated.

As Figure 1-3, paddy field field weeding hoe, including harrow frame 1, rake knife 5, lifting screw 9, harrow frame 1 is by longitudinal rod 2 and horizontal stroke Formed to bar 3, longitudinal rod 2 and 3 orthogonal welding of transverse bar, be provided with four through holes 4 on transverse bar 3, inserted with liter in each through hole 4 Screw rod 9 drops；The first nut 10 has been inserted at the top of lifting screw 9, and the first nut 10 is located above transverse bar 3, positioned at transverse bar 3 The second nut 11 is inserted on the lifting screw 9 of lower section, the bottom of lifting screw 9 is fixed with rake knife 5, and the bottom of rake knife 5 is fixed There is tooth form knife 6, the both sides for harrowing the bottom of knife 5 are extended with two fix bars 7, and steel wire 8 is wound between two fix bars 7；Harrow knife 5 Concave surface be cambered surface；Steel wire 8 is located at before tooth form knife 6.

In use, adjusting the height of lifting screw 9 according to the height of the seedlings of cereal crops, then pass through the first nut 10 and the second nut 11 Carry out fixed lateral bar 3, paddy field weed-killer rake is put into the spacing of rice, the corresponding spacing of a rake knife, people pulls paddy field to remove Harrow, first steel wire 8 cut off the rhizome of plant, and then tooth form knife 6 collects weeds, and the cambered surface for harrowing knife is easy to make weeds roll, After one ridge has been harrowed, the weeds harrowed in knife cambered surface are taken out and treaded in into paddy field.

Claims

1. paddy field weed-killer is harrowed, including harrow frame, rake knife, lifting screw, it is characterised in that harrow frame is made up of longitudinal rod and transverse bar, Longitudinal rod welding orthogonal with transverse bar, is provided with four through holes on transverse bar, inserted with lifting screw in each through hole；Lifting screw The first nut has been inserted at top, and the first nut is located above transverse bar, has been inserted on the lifting screw below transverse bar Second nut, the bottom of lifting screw are fixed with rake knife, and the bottom for harrowing knife is fixed with tooth form knife, harrow the both sides extension of the bottom of knife There are two fix bars, steel wire is wound between two fix bars.

2. paddy field weed-killer rake according to claim 1, it is characterised in that the concave surface for harrowing knife is cambered surface.
