Description
Technical Field
The utility model belongs to the technical field of agricultural tobacco machinery, and particularly relates to a well cellar type transplanter cellar forming mechanism for viscosity-reducing desorption.
Background
The Chinese tobacco sales volume is the first in the world, and plays an important role in the development of national economy in China. The conventional transplanting modes mainly comprise a conventional transplanting mode, a film tobacco transplanting mode, a seedling film tobacco seedling transplanting mode, a conventional well pit transplanting mode and a well pit film tobacco seedling transplanting mode. Experimental research shows that the well cellar transplanting technology is most beneficial to the growth of tobacco seedlings in the early stage. The pit-type crop transplanting machine can improve the mechanization level of pit-type transplanting, reduce the labor cost, improve the efficiency and promote the economic development of crops in areas.
The existing pit-type transplanting cavitation drill bit in the market mainly comprises a top-type drill bit and a spiral blade-type drill bit, wherein the cavitation mechanism of the top-type drill bit is compaction forming, the manufactured pit is good in stability and not easy to collapse, but the inner wall of the pit is smooth, and growth and development of tobacco seedlings in the early stage are not facilitated; when the rainfall is large, water is accumulated in the pit, and the phenomenon of seedling flooding can be caused. The cavitation mechanism of the spiral blade type drill bit is cutting and forming, the compactness of the inner wall of the pit manufactured by the spiral drill bit is small, the soil is loose, the growth and development of tobacco seedlings in the early stage are facilitated, but the pit is easy to collapse due to the small compactness of the pit and the loose soil, the pit depth is not uniform due to the fact that the soil falls back after the drill bit is pulled out, and the planting depth is not uniform.
The chinese patent with application number 201910788216.1 discloses a pit hole boring drill bit, and the lower extreme of center pin is fixed with the trompil drill point, is fixed with helical blade from trompil drill point department to middle part, from middle part to upper end fixedly connected with tile form blade, and tile form blade and helical blade butt joint, tile form blade set up along the length direction of center pin, also can reach the requirement of pit transplanting technique in pit hole appearance, quality to improve the growth quality of tobacco seedling early stage transplanting seedling and the production quality of later stage flue-cured tobacco. However, the drill bit has soil adhesion phenomenon, so that the working efficiency and the working quality of the machine are seriously affected, and the energy consumption is increased.
The well cellar type transplanting technology is widely applied to tobacco seedling transplanting, can effectively promote early growth and development of tobacco seedlings in the seedling stage, can effectively improve the production quality of tobacco leaves, but the phenomenon of soil adhesion is ubiquitous, so that the working efficiency and the operation quality of machinery are seriously affected, and the energy consumption is increased. When soil adhesion is too much on the drill bit, dynamic unbalance of the drill bit during working can be caused, vibration is generated, operation is not facilitated, cavitation quality is reduced, and meanwhile the soil discharging function of the drill bit can be affected. Therefore, the method is particularly important for the research of the viscosity reduction and desorption of the drill bit.

Detailed Description
As shown in fig. 1-4, a well cellar type transplanting machine cellar forming mechanism for reducing viscosity and desorption comprises a rotating shaft 1, wherein tile type blades 2, helical blades 3 and a drill tip 4 are sequentially arranged on the rotating shaft 1 from top to bottom, helical reinforcing ribs 7 are arranged on the surface of the drill tip 4, and convex hulls 8 are uniformly arranged on the upper surface of the helical blades.
Because the inner wall of the pit manufactured by the helical blades is rough, the compactness of the pit is small, the pit is easy to collapse due to loose soil, and the pit depth is not uniform due to the fact that the soil falls back after the drill bit is pulled out; the pit manufactured by the tile type blades has good stability and is not easy to collapse, but the inner wall of the pit is smooth, which is not beneficial to the growth and development of tobacco seedlings in the early stage; when the rainfall is large, water is accumulated in the pit, and the phenomenon of seedling flooding can be caused. In the utility model, when the drill bit is designed, the cavitation mechanism of the upper blade of the drill bit is designed to be compact-forming, and the cavitation mechanism of the lower blade of the drill bit is cutting-forming; the upper part of the drill bit adopts tile type blades, and the lower part adopts spiral blade type blades, so that the stability of the top of the well pit can be ensured, the inner wall of the well pit can be roughened, the soil is loose, and the growth and development of the tobacco seedlings in the early stage are facilitated. The drill point adopts the toper, and design spiral reinforcement rib 7 on its surface, and the toper drill point has cutting ability at first, can cut the soil body once, has added reinforcement rib 7 and has been equivalent to increasing the cutting tooth number of drill bit. The helical blades 3 and the helical reinforcing ribs 7 on the surface of the drill tip can effectively dredge soil and prevent soil accumulation.
The surface of the helical blade 3 is formed into a non-smooth structure by a plurality of convex hulls 8, so that the contact and adhesion area of the helical blade and soil can be effectively reduced, and an important effect is played on desorption and drag reduction of the helical blade.
Further, the radius of the convex hull 8 is 2-4mm. Most preferably, the convex hull radius is 2mm. The radius of the convex hull can be reasonably adjusted and determined according to the size of the helical blade 3.
The visbreaking and desorption principle of convex hulls: as shown in fig. 4, the drill bit rotates at a high speed and soil moves rightward with respect to the drill bit. Due to the effect of the convex hull, the soil flow slides upwards along the spherical crown of the convex hull, and a water film between the soil and the surface of the drill bit is broken, so that the adhesion between the soil and the surface of the drill bit is reduced; meanwhile, when the soil rapidly passes through the spherical crown surface, the soil obtains upward parting speed, so that the positive pressure between the soil and the spiral blade is reduced, and the adhesion between the soil and the drill bit is reduced; from the analysis in the two aspects, the adhesion between the soil and the drill bit is weakened, so that the effect of viscosity reduction and desorption is achieved.
Further, the lower surface of the helical blade 3 is provided with cutter teeth 5, and both sides of the cutter teeth 5 are provided with guide ribs 6. In the preferred scheme, two guide ribs 6 are arranged at left and right sides.
The cutter teeth 5 arranged on the lower surface of the helical blade 3 cut soil secondarily, two guide ribs 6 are respectively designed on two sides of the cutter teeth 5, and scattered soil is smoothly discharged to above the helical blade 3 along the guide ribs 6, so that soil under the helical blade is not accumulated, as shown in fig. 3.
Further, the thickness of the reinforcing ribs 7 is smaller than that of the guide ribs 6.
The cellar forming mechanism (drill bit) is connected with a transplanting machine through a flange 9 at the top of the rotating shaft 1, a controller of the transplanting machine controls a crank to rotate to drive the cellar forming mechanism (drill bit) to descend, the cellar forming mechanism (drill bit) rotates to work into holes, and finally the cellar forming mechanism (drill bit) ascends back, the transplanting machine moves, and the next seedling hole is manufactured. The description of this working process is a mature technology in the art, and the present utility model will not be described in detail.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
