Abstract
The utility model discloses an anti-winding toolbox of a tillage machine. The anti-winding toolbox comprises a tool shaft, tool aprons and blades, wherein the tool aprons are fixedly connected to the tool shaft through arc seaming edges, the blades are fixedly connected into the tool aprons, the lower parts of the tool aprons extend along the arc directions of the arc seaming edges, and form arc-shaped sharp corners along with the gradual reduction of width, further improvement is that the tool aprons are arranged along spiral lines on the outer wall of the tool shaft, the spiral angles of the spiral lines for the tool aprons are 5-15 degrees, one sides, opposite to the arc seaming edges, of the arc-shaped sharp corners are provided with grass cutting edges, and the central axis of each tool apron and blade mounting hole is offset for a certain distance from the center of the tool shaft. The anti-winding toolbox has the beneficial effects that the tool shaft is prevented from being wound with grass and straws, so that the workload of manual cleaning is obviously reduced, and the working efficiency is improved; the tool shaft is small during use, and the working stability is good.
Description
Technical field
The utility model relates to a kind of harvesting and tillage machine toolbox.
Background technology
Along with agriculture development, harvesting and tillage machine is widely used in agricultural production.Existing harvesting and tillage machine toolbox comprises cutter shaft, tool rest, blade; Tool rest is fixedly connected on cutter shaft by circular arc seam limit, blade is fixedly connected in tool rest, in this toolbox operation process, be prone to and hang grass, hang the situation that stalk makes cutter shaft twine grass, twine stalk, increased the power consumption of rotary cultivator attachment, reduced operation quality, when serious, can make machinery work, for making the normal operation of machinery, people need manual cleanup, thereby cause the waste of human and material resources resource.
Summary of the invention
The utility model is for the deficiencies in the prior art, proposes a kind ofly can avoid cutter shaft to twine grass, twine stalk, significantly reduces labor cleaning's workload, the antiwind toolbox of harvesting and tillage machine of increasing work efficiency.
The utility model is achieved through the following technical solutions technical goal.
The antiwind toolbox of harvesting and tillage machine, comprises cutter shaft, tool rest, blade; Tool rest is fixedly connected on cutter shaft by circular arc seam limit, and blade is fixedly connected in tool rest; Its improvements are: extend along circular arc seam limit circular arc direction described tool rest bottom, and width diminishes gradually, form arc wedge angle.
Further improve and be: described tool rest is arranged along the helix of cutter shaft outer wall.
Further improve and be: the helical angle of arranging the helix that is used for tool rest is 5～15 °.
Further improve and be: the opposing side in described arc wedge angle and circular arc seam limit is provided with chaffcutter sword.
Further improve and be: the distance that described tool rest blade installing hole central axis and cutter shaft off-centring are certain.
The utility model compared with prior art, has following good effect:
1 tool rest bottom is provided with arc wedge angle, during work, the weeds at cutter shaft outer rim place and straw are along the slip of arc wedge angle and away from cutter shaft center, thereby make cutter shaft straw winding and straw, like this, the utility model is when work, rotary tillage consumed energy is little, and operation quality is high, prosthetic is often cleared up, and operating efficiency is high.
2. arc wedge angle is provided with chaffcutter sword, not only can make weeds and stalk away from cutter shaft center during work, also can cut off weeds and stalk, further stops cutter shaft to be wound around by weeds and stalk, significantly improves operating efficiency.
3. blade installing hole center and cutter shaft off-centring, increased the arm of force of blade cut power, under equal torque condition, obviously reduced the cutting force of blade, improved the service life of blade.
4. tool rest is arranged along the helix of cutter shaft outer wall, make harvesting and tillage machine set of knives in rotary course, a period in office only has a cutter in putting forth effort state, sheet in whole like this cutter group just can be progressively to root stubble with earth cuts off and broken, overcome the severe impact that existing harvesting and tillage machine set of knives produces because of intermittent operation and the defect of beating.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
The cutter of harvesting and tillage machine shown in accompanying drawing group, comprises cutter shaft 1, tool rest 2, blade 4; Tool rest 2 is fixedly connected on cutter shaft 1 by circular arc seam limit 2.1, and blade 4 is fixedly connected in tool rest 2; Tool rest 2 bottoms are 2.1 circular arc directions extensions along circular arc seam limit, and width diminishes gradually, forms arc wedge angle 2.2, and in the present embodiment, the opposing side in arc wedge angle 2.2 and circular arc seam limit 2.1 is provided with chaffcutter sword 2.3.
The distance that tool rest 2 blade installing hole central axis and cutter shaft 1 off-centring are certain.
