Description

 The invention relates to agricultural machinery, in particular to working bodies for tillage.

 Known tools for subsurface / chisel / tillage / see "Recommendations on the use of chisel tools" Gosagroprom of the USSR, VIM, M., 1988 /, providing significant / up to half a meter / tillage with relatively low traction resistance. However, the working bodies of this type are intended only for the destruction of the plow sole and do not provide sufficient crumbling of the undercut layer of the soil layer.

 More effective is a tillage implement on a. with. N 1436898, A 01 B 35/20, 1988, comprising a stand and a curved knife with two curved blades. However, such a working body does not allow for complete crumbling of the soil layer, since the transverse compression of the cut-off soil volume occurs only on one side of the knife with the blade adjacent to the stand.

 In addition, the complexity of the design of the working body leads to an increase in the complexity of the technological process of its manufacture, and the large length of the working part of the knife increases the traction resistance of the gun.

 The technical problem posed before the invention is to increase the efficiency of crumbling soil, simplifying the design and reducing traction resistance.

образным, в котором плоскость вертикальной стойки и образующие изогнутого ножа совпадают с направлением движения почвообрабатывающего орудия. К режущей /изогнутой/ части ножа своими основаниями закреплены асимметричные зубья, которые наклонены к нижней поверхности упомянутого ножа. Форма поверхности зубьев совпадает с формой изгиба ножа, а их длинная сторона обращена к вертикальной стойке рабочего органа.The goal is achieved in that the working body is made

figurative, in which the plane of the vertical rack and the generators of a curved knife coincide with the direction of movement of the tillage implement. To the cutting / curved / part of the knife, asymmetrical teeth are fixed with their bases, which are inclined to the lower surface of the said knife. The shape of the surface of the teeth coincides with the shape of the bend of the knife, and their long side faces the vertical strut of the working body.

образного рабочего органа почвообрабатывающего орудия обеспечивает эффективное крошение почвы всей рабочей поверхностью ножа за счет того, что наклоненные к низу зубья, внедряясь в почву, подрезают и обжимают ее своими изогнутыми поверхностями по всему объему пласта. Далее подрезанный и обжатый пласт, проходя по изогнутой поверхности ножа, разрушается и при сходе с его рабочей части образует мелкокомковатый однородный слой, соответствующий всем требованиям агротехники. Такая форма рабочего органа и размещение зубьев на нем способствуют подрезанию, обжатию и крошению обрабатываемого слоя почвы по всему периметру ножа. Кроме того, простота конструкции

образного рабочего органа облегчает технологичность ее изготовления, а сменные зубья позволяют использовать форму ножа любой конфигурации.Suggested Design

the figurative working body of the tillage implement provides effective crumbling of the soil with the entire working surface of the knife due to the fact that the teeth tilted to the bottom, penetrating into the soil, cut and compress it with their curved surfaces throughout the volume of the formation. Further, the cut and squeezed layer, passing along the curved surface of the knife, collapses and, upon leaving its working part, forms a finely crumpled homogeneous layer that meets all the requirements of agricultural technology. This form of the working body and the placement of the teeth on it contribute to the cutting, crimping and crumbling of the treated soil layer around the entire perimeter of the knife. In addition, simplicity of design

a figurative working body facilitates the manufacturability of its manufacture, and interchangeable teeth allow you to use the shape of a knife of any configuration.

образного рабочего органа обеспечивает снижение тягового сопротивления, так как плоскость стойки и образующие поверхности ножа совпадают с направлением его движения, тем самым уменьшая площадь соприкосновения режущей части с обрабатываемым пахотным слоем.Design

shaped working body provides lower traction resistance, since the plane of the rack and the forming surface of the knife coincide with the direction of its movement, thereby reducing the area of contact of the cutting part with the treated arable layer.

 The asymmetry of the teeth with the location of their long edges in the direction of the rack prevents possible lateral displacement of the working body during its movement.

 In FIG. 1 shows a General view of the proposed working body of the tillage implement; in FIG. 2 - the same front view; in FIG. 3 is a section AA in FIG. 2; in FIG. 4 is a cross-section BB in FIG. 2; in FIG. 5 - scan of the cutting part of the knife with teeth; in FIG. 6 - crumbling of the soil by the working body.

образным, содержит вертикальную стойку 1, нижняя часть которой переходит в изогнутый нож 2. К режущей части ножа 2 основаниями 3 с помощью болтов 4 прикреплены асимметричные зубья 5, отогнутые к наружной поверхности ножа 2. Поверхность зубьев 5 изогнута так, что она повторяет поверхность изгиба ножа 2, а длинные кромки /стороны/ 6 зубьев 5 обращены к стойке 1 рабочего органа. Причем изгиб ножа 2 может быть выполнен в виде части цилиндрической поверхности, либо поверхности, образованной кривыми 2-го порядка.The working body of the tillage implement, made

figuratively, contains a vertical stand 1, the lower part of which goes into a curved knife 2. To the cutting part of the knife 2 with bases 3 with the help of bolts 4 are attached asymmetric teeth 5, bent to the outer surface of the knife 2. The surface of the teeth 5 is curved so that it repeats the surface of the bend knife 2, and long edges / sides / 6 teeth 5 facing the rack 1 of the working body. Moreover, the bend of the knife 2 can be made in the form of a part of a cylindrical surface, or a surface formed by curves of the 2nd order.

 The plane of the rack 1 of the working body and the generators of the bend of the knife 2 coincide with the direction of movement of the working body. For manufacturability and depending on the wear of the teeth 5 they are made interchangeable.

образным рабочим органом плоскость стойки 1 и образующие изгиба ножа 2 совпадают с направлением движения почвообрабатывающего орудия, что снижает его тяговое сопротивление. При этом за счет того, что зубья 5 отогнуты к нижней поверхности ножа 2, обеспечиваются необходимое внедрение рабочего органа в почву и ее деформация. Затем подрезанный пласт /фиг. 6/ обжимается изогнутыми поверхностями зубьев 5, разрушается и передается на внутреннюю поверхность ножа 2. На линии перегиба зубьев 5 и переходе на внутреннюю поверхность ножа 2 происходит дополнительное крошение пласта с достаточной однородностью его комкования.The working body of the tillage implement works as follows. When processing

the figurative working body, the plane of the rack 1 and the generators of the bend of the knife 2 coincide with the direction of movement of the tillage implement, which reduces its traction resistance. Moreover, due to the fact that the teeth 5 are bent to the lower surface of the knife 2, the necessary introduction of the working body into the soil and its deformation are provided. Then the trimmed layer / Fig. 6 / is crimped by the curved surfaces of the teeth 5, is destroyed and transferred to the inner surface of the knife 2. On the inflection line of the teeth 5 and the transition to the inner surface of the knife 2, additional crumbling of the formation occurs with sufficient uniformity of its clumping.

 Due to the fact that the long edges 6 of the teeth 5 are turned towards the rack 1, lateral displacement of the working body during its movement is prevented.

 The test results of the proposed working body showed that the quality of crumbling of the arable layer / size of fractions less than 50 mm / was 80 ... 90%, while the traction resistance of the working body in comparison with the prototype was reduced by 20 ... 22%. The proposed configuration of the working body provides a fairly simple technology for its manufacture, and interchangeable teeth allow you to select the optimal bend of the knife of the working body in accordance with the technological conditions of the arable layer.
