Detailed description of the invention
Fig. 1 is structural representation of the present utility model, the rotary cultivator attachment as it can be seen, the brush of the present embodiment is hoed up weeds, including capstan head 1 and along the circumferentially distributed multiple blades of described capstan head 1, and described blade is respectively provided on two sides with rotary tillage blade 3 and brush is hoed up weeds sword 2;When needs to perennial weeds carry out farming time, can drive at rotary cultivator tool cutter and axle is installed this brush hoe up weeds rotary cultivator attachment, control brush hoe up weeds rotary cultivator attachment rotate forward time, rotary tillage blade 3 is used to carry out rotary tillage process, during reversion, brush sword 2 of hoeing up weeds is used to carry out brush and hoe up weeds operation, therefore, only need to control the forward or reverse of this rotary cultivator attachment, the tillage method of limit brush grass limit rotary tillage can be carried out, additionally, when this rotary cultivator attachment is installed, it axially advances consistent with rotary cultivator, it is wrapped in the weeds foreign material on this rotary cultivator attachment can produce to pull and self falling with earth in advance process, therefore, this rotary cultivator attachment thoroughly solve existing rotary cultivator can not farming perennial weeds ground a difficult problem.
In the present embodiment, described blade is axially inclined along capstan head 1;When this rotary cultivator attachment is installed, it axially advances consistent with rotary cultivator, its rear end is downward-sloping simultaneously makes shape between the axis of rotary cultivator attachment and horizontal plane form an angle, blade is axially inclined along capstan head 1, make blade perpendicular to the ground when rotating to capstan head 1, soil tilling depth is made to reach pre-provisioning request, thus ensure that cultivating quality, owing to the axis of rotary cultivator attachment forms an angle with horizontal plane shape, rotary cultivator attachment will produce along the axial counteracting force of capstan head 1 in cutting soil course, this counteracting force has two component, it is make rotary cultivator thrust forward and lift upwards respectively, thrust forward can drive rotary cultivator to advance, and the lift upwards that rotary blade produces can be prevented effectively from rotary cultivator and get deeply stuck in when farming marshy land, alleviate the labor intensity of operating personnel, improve soil cultivation efficiency.
In the present embodiment, described rotary tillage blade 3 is arcuate blade;Blade is tangentially connected by arc transition with capstan head 1 cylindrical simultaneously, therefore, bury from root during blade work, in the way of sliding cutting, enter soil and process of burying is impacted less, ensure that blade cutting resistance of burying is less, this sliding cutting formula of blade is buried the mode of farming hard place, compared with burying with the existing rotary tillage power blader formula of hitting, after the blade embedded depth of the present embodiment reaches designing requirement, machine occurs jumping phenomena hardly, and then solve tradition rotary cultivator vibrate greatly when farming hard place, tilth is unstable, operation easier is big, easily congruence problem out of control and uneasy.
In the present embodiment, described blade includes the inner and is fixed on the rotary blade 4 of capstan head 1 periphery and brush is hoed up weeds cutter 5, and described rotary blade 4 is fixed for arc and its outer end and brush cutter 5 of hoeing up weeds;Rotary blade 4 and brush are hoed up weeds, and cutter 5 is inner solderable is connected to capstan head 1 periphery, and the two outer end is interconnected to form the U-shaped blade of hollow structure, and therefore, its processing and manufacturing difficulty is relatively low, is effectively reduced the deadweight of rotary cultivator attachment, improves the structural strength of blade simultaneously.
In the present embodiment, between described blade and capstan head axis, the angle α of formation ranges for 20 ° of < α < 40 °;The angle α of this enforcement is preferably 30 °, the blade of this enforcement is cambered blade, therefore, angle α is the angle between the blade projection to capstan head 1 longitudinal cross-section and capstan head 1 axis, this rotary cultivator attachment is when mounted, its angle axially downwardly tilted is equal with angle α, with ensure blade 4 when rotating to capstan head 1 perpendicular to the ground.
In the present embodiment, the radius of curvature r of described rotary tillage blade 3 ranges for 100mm < r < 300mm, the radius of curvature r of the present embodiment is preferably 115mm, the radius of curvature of blade can at utmost reduce within the scope of this rotary tillage blade 3 bury cutting resistance, meanwhile, the cultivating quality of soil is improved.
In the present embodiment, the radius of turn R of described blade ranges for 100mm < R < 300mm, the radius of turn R of the present embodiment is preferably 200mm, thus ensureing that this rotary cultivator attachment has bigger job area, guarantee that the active force of blade and soil is in the tolerance range of blade, it is to avoid operation fractures simultaneously.
In the present embodiment, described rotary tillage blade 3 and brush are hoed up weeds and are seamlessly transitted between sword 2;Make rotary tillage blade 3 and brush hoe up weeds sword 2 connect formed a circular blade, this attachment structure can be effectively improved the intensity of two cutter link positions.
In the present embodiment, described capstan head 1 is provided with polygon installing hole, and the installing hole of the present embodiment is regular hexagon hole, and the tool driving shaft of rotary cultivator also has the shaft part of regular hexagonal section, is coordinated with installing hole thus driving this rotary cultivator attachment to rotate by this shaft part.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
