Abstract
The utility model relates to a paddy field circumrotating and loosening harrow knife which relates to an operation component of harrow machines of the paddy field in agricultural machinery. The front part of a knife handle is provided with a side cutting part and a front end part, the bent direction of the knife handle is opposite to the bent direction of the front end part, and the entirety is in an S shape or an inverse-S shape. Bent folded lines between the front end part and the side cutting part are positioned under a horizontal line in the included angle of alpha. A tangent blade and a side cutting blade of the front end part and the side cutting part together form the blade edge line in a circular arc archy shape. The knife has the advantages of reasonable structural design, strong soil entering ability, strong crumbled soil mixing ability and low cultivating resistance. The soil circumrotating and loosening operation with water and the slurry stirring operation of the original stub land of the paddy field can be completed. The utility model has the obvious characteristics of consumption decrease, yield increase, high efficiency and water saving.
Description
Technical field
The utility model relates to the operation part on the paddy field furrowing and harrowing machine tool in the agricultural machinery.
Background technology
Traditional ground making of paddyfield, mainly be adopt uncovering plough turn over or the rotovator rotary tillage after soaked, the method that repeatedly rolls of water harrowing wheel is finished the operation of hack rake slurry again.The water harrowing wheel is to substitute drive wheel of hand tractor, and by a pair of iron tyre that the one group of steel plate that keeps at a certain distance away is welded, they split the both sides at hand tractor.Water harrowing wheel hack rake slurry mainly is by passive rolling, the pass of facility operation is many, efficient is low, the slurry layer is shallow and extremely inhomogeneous, cause in the growth process of riceplant percolation water serious, not only reduced the water temperature in the rice field, wasted great amount of water resources, and percolation water takes away a large amount of nutrients, influenced growing of paddy rice.In recent years, the paddy field ground harrowing and leveling machine begins to replace traditional ground making of paddyfield mode, be that passive type water harrowing wheel is finished the operation of hack rake slurry, but because the cultivated rake cutter general structure design of its main working parts is unreasonable, the cutter ability of burying during its operation, tillage resistance is big, and the Tu Fa that downcuts is not had panting action, and the band water that especially can not bear and finish the former stub land in paddy field unscrews with hack and stirs the slurry operation.
Summary of the invention
The purpose of this utility model is exactly for overcoming the problem and shortage that prior art exists, design provides a kind of novel paddy field circumrotating and loosening harrow knife, reaches the ability of burying when improving the cutter operation, reduces tillage resistance, produces the panting action that downcuts Tu Fa, improves the paddy field and unscrew and plough the rake quality, adapt to and satisfy the purpose that the former stub land mechanization in paddy field requires wholely.
Basic design of the present utility model is, on the handle of a knife front portion, be provided with side and cut portion and leading section, its leading section and side are cut and are between the portion to a lateral buckling planform, and handle of a knife and side are cut and be provided with between the portion and the rightabout bending of leading section, and integral body is " S " or anti-" S " shape; The crooked crease line that leading section and side are cut between the portion is positioned at the horizontal line below, and constitutes the α angle with horizontal line, and this α angle is between 5-15 °; Cut in leading section and side and to be respectively equipped with positive cutting blade and side cutting blade in the portion, and constitute the cutting edge line of circular curve shape, so far constitute the paddy field circumrotating and loosening harrow knife.
The utility model structural design is new reasonable, and the ability of burying and hack stirring capacity are strong, and tillage resistance is little, and the band water that can be competent at the former stub land in paddy field fully unscrews with hack and stirs the slurry operation, has the outstanding feature of consumption reduction, synergy, water saving, volume increase.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that A among Fig. 1 is to view;
Fig. 4 is the B-B profile among Fig. 1.
Piece number explanation among the figure:
1, handle of a knife, 2, side are cut portion, 3, leading section, 4, positive cutting blade, 5, cutting edge line, 6, side cutting blade, 7, crooked crease line.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The paddy field circumrotating and loosening harrow knife comprises handle of a knife 1, on handle of a knife 1 front portion, be provided with side and cut portion 2 and leading section 3, its leading section 3 and side are cut and are between the portion 2 to a lateral buckling planform, handle of a knife 1 and side are cut and are provided with between the portion 2 and leading section 3 rightabout bendings, and circumrotating and loosening harrow knife integral body is " S " or anti-" S " shape.The crooked crease line 7 that leading section 3 and side are cut between the portion 2 is positioned at the horizontal line below, and constitutes the α angle with horizontal line, and this α angle is between 5-15 °.Cut in leading section 3 and side and to be respectively equipped with positive cutting blade 4 and side cutting blade 6 in the portion 2, and constitute the cutting edge line 5 of circular curve shape.
When operation is used, the rake cutter is ploughed in this paddy field to be fitted on the cultivated rake of the driving type rotor admittedly, and with the rotor fast rotational, utilize the cutting edge line 5 of the circular curve shape of positive cutting blade 4 and side cutting blade 6 compositions, and the angle of leading section 3 and the formation of field face, produce than big sliding cutting power with to downcutting the panting action of Tu Fa, fulfil assignment, strengthened the hack function; The existence of α angle has improved the cutter ability of burying, and has reduced tillage resistance.
