Abstract
The invention discloses a pull-type land bed leveling device. The pull-type land bed leveling device is formed by a first spiral shaft, a second spiral shaft and a tooth rake which are arranged in a frame support in parallel, and the work width of the frame support ranges from 1430 cm to 2100 cm. The first spiral shaft and the second spiral shaft are provided with a first spiral cutting blade and a second spiral cutting blade which are different in rotating direction respectively, sawteeth evenly distributed are arranged on the outer edge of the first spiral cutting blade and the outer edge of the second spiral cutting blade respectively, and the directions of the saw tips of the sawteeth are identical with the forward moving direction of the first spiral cutting blade and the forward moving direction of the second spiral cutting blade respectively. Evenly-distributed tiny pointed teeth are arranged at the lower end of the tooth rake, and the length of the pointed teeth ranges from 1 cm to 2 cm. The pull-type land bed leveling device is fixed to a fixing frame of a pull machine, the height of the frame support is vertically adjusted through a third nut on a bolt, and thus the mechanical leveling work for a land bed can be achieved. The pull-type land bed leveling device is good in leveling effect, especially suitable for spreading tiny seeds and very obvious in working efficiency.
Description
Technical field
The present invention relates to agricultural machinery technical field, especially a kind of towed ground furrow smoother.
Background technology
Peasant do ground furrow time need smooth furrow face, be all for a long time adopt hoe, creeper after breaking soil block into pieces more repeatedly push-and-pull fulfil assignment.The labour intensity of this work is very large, expends much muscle power and time.When local furrow are for disseminating tiny seed, high especially to the flatness requirement in furrow face, only rely on these simple and crude farm implements of hoe, creeper to carry out smooth, efficiency is more low, also affects the emergence rate of seed.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of not only planarization effects good, be particularly useful for disseminating tiny seed and work efficiency significant especially towed ground furrow smoother.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: towed ground furrow smoother, is made up of the first helical axis be arranged in parallel within frame rack, the second helical axis and tooth harrow, and the work wide cut of frame rack is 1430-2100cm.
The first described helical axis and the second helical axis are respectively equipped with the first contrary spiral cutting sheet of direction of rotation and the second spiral cutting sheet.
The first described spiral cutting sheet and the second spiral cutting sheet outer rim are respectively equipped with uniform sawtooth, and the saw point of sawtooth is identical with the reach direction of the second spiral cutting sheet with the first spiral cutting sheet respectively.
The lower end of described tooth harrow is provided with uniform, tiny pointed tooth, and the length of pointed tooth is 1-2cm.
The diameter of axle at the first described helical axis and the second helical axis two ends respectively be fixed on frame rack below bearing block in bearing bore diameter coordinate.
The quadrate support bar at described tooth harrow two ends is through frame rack, and the end of quadrate support bar is provided with the first screw rod and uses the first fastening nuts respectively.
The top of described frame rack is provided with the hitch frame vertical with frame rack, and the end of the cant beam of hitch frame is provided with the bolt by the 3rd nut up-down adjustment frame rack height, and the present invention is fastened on the fixed mount of hauling machine by the second nut.
Described frame rack is assembled by each second screw rod of two rectangular steel tubes and front and back, and with the 4th fastening nuts together.
Be arranged in parallel within the first helical axis in frame rack and the second helical axis owing to being respectively equipped with the first spiral cutting sheet and the second spiral cutting sheet, and the first spiral cutting sheet and the second spiral cutting sheet outer rim are respectively equipped with uniform sawtooth, the saw point of sawtooth is identical with the reach direction of the second spiral cutting sheet with the first spiral cutting sheet respectively, this structure makes the soil block of the present invention to furrow face have powerful crushing function, and the soil particle after fragmentation is not only thin but also even; Meanwhile, because the direction of rotation of the first spiral cutting sheet and the second spiral cutting sheet is contrary, the soil relative movement of the table of the right and left furrow face differing heights can be made and realize good planarization effects.
Ground furrow through the first spiral cutting sheet and the second spiral cutting sheet and the uniform sawtooth of outer rim broken, smooth after, the pointed tooth that tooth harrow arranged in parallel is below uniform, tiny because lower end is provided with, the length of pointed tooth is 1-2cm, can scratch in smooth furrow face that a rule is uniform, Tu Gou that is tiny, degree of depth 1-2cm, when disseminating tiny seed, seed can drop in native ditch equably, unlikely unordered rolling and gathering everywhere; Only need floating furrow face, the seed in native ditch can be buried in the earth, easily complete sowing work.
The present invention is fastened on the fixed mount of hauling machine, base area furrow differing heights, makes the present invention and furrow face close contact by the 3rd nut up-down adjustment frame rack height, the mechanization leveling operation of furrow over the ground can be realized.
The present invention not only planarization effects is good, and be particularly useful for disseminating tiny seed, work efficiency is remarkable especially.
