Description
Art
The utility model relates to a kind of farmland arranged by three row's rake groups of blade unit combination and harrows wholely, has larger solid space, can be combined into the farmland that many row's rake groups arrange harrow wholely by blade unit between especially each blade unit.
Background technology
At present, it is all by blade with square shaft that known farmland is harrowed wholely, spacer tube is worn into a string, the rake group of formation spaced apart for blade between blade with multiple spacer tube, these spacer tubes form a thick axle between blade, the space between natively little blade is made to become less, often result in blockage in operation and affect operation, again due to a string rake group use two bearings, the axial force of one group of blade all acts on these two bearings, so the damage that bearing is frequent, change bearing also whole rake assembling and dismantling to be opened, waste time and energy, wrong farming season, whole string rake group inclination certain angle realizes by the angular adjustment that this farmland is harrowed wholely, except needing the angular adjustment parts that cover is complicated greatly, also make whole structure of harrowing become huge, rake body is spun out, result is that a rake can only arrange front and back two string group rake group, the hack effect of raking the soil level is not ideal enough, multipass operation have to be leaned on just to reach agriculture requirement, duty cycle extends, fuel consumption strengthens, operating cost increases.
Summary of the invention
In order to overcome existing farmland whole to harrow in operation easily block, bearing is fragile, operation pass is many deficiency, the utility model provides a kind of farmland arranged by three row's rake groups of blade unit combination to harrow wholely.
The utility model solves the technical scheme that its technical problem adopts: blade unit is primarily of U-shaped clamp, rake leg, hub bearing and blade are formed, rake leg is by dull and stereotyped and vertical leg seam, flat board there is the hole of 8 diverse locations, vertical leg steel plate is compressing, vertical leg bottom is also pressed with 11 ° of cambers and installs the hole of hub bearing, vertical leg top and plate welding, found leg corresponding flat board during welding and reverse 13 ° to the left or to the right, become levorotation and right type two class rake leg, levorotation rake leg and right type rake leg are symmetrical, hub bearing inner ring flange is connected fastening with vertical leg bottom, hub bearing outer shroud flange is connected fastening with blade, form 1 blade unit, blade unit is installed at a certain distance on frame square beam, form a string rake group, frame square beam one has 3, harrowing of composition three row's rake group arrangement wholely.U-shaped clamp is coordinated to snap fitted on frame square beam from the hole of diverse location on rake leg flat board and can obtain different blade angles.
The beneficial effects of the utility model are, adopt blade unit can be combined into harrowing of three row's rake group arrangements wholely, and have independently space between every sheet blade, the soil that blade has been harrowed can very smoothly by the space between blade, solve blockage problem between blade, can combine according to actual needs with blade unit, the rake group row of harrowing and fabric width also can mate according to tractor watt level wholely, be convenient to form multiple different series rake, make the rake structure simplification of whole ground, manufacturing cost declines, operation pass reduces, operating cost reduces.

Embodiment
In FIG, the vertical leg (8) of rake leg (4) reverses 13 ° when welding with dull and stereotyped (7) to the left or to the right, lower end is connected fastening with the inner ring flange (6) of hub bearing (3), and blade (1) is contained on the outer shroud flange (5) of hub bearing (3), constitutes 1 blade unit.
In fig. 2, hub bearing (3) has two flange, is outer shroud flange (5) and inner ring flange (6) respectively.
In figure 3, rake leg is made up of dull and stereotyped (7) and vertical leg (8) seam, dull and stereotyped (7) there is the hole of 8 diverse locations, vertical leg (8) is compressing with steel plate, vertical leg (8) bottom is pressed with 11 ° of cambers and is used for the hole of matching with the inner ring flange (6) of hub bearing (3), top and plate welding, found leg (8) corresponding dull and stereotyped (7) during welding and reverse 13 ° to the left or to the right, become levorotation and right type two class rake leg, levorotation and right type rake leg are symmetrical.
