Description

Plowshare

The present invention relates to a plowshare, and more particularly to a plowshare that can be used for shoveling, turning soil, plowing fields, and the like.

Referring to Figures 1, 2 and 3, a conventional plowshare is used for mounting on the bottom of a farm implement such as a cultivator, a boring machine, a ploughing machine, etc. (not shown). The plow head comprises an arc rake 1 and a connecting block 2.

The arc plough 1 includes a plate body 11, a ridge rib 12 projecting longitudinally from a center of a top surface of the plate body 11, and a joint edge 13 extending from an upper end of the plate body 11 to the upper rear. The plate body 11 is a piece of curved plate extending from the top to the bottom and gradually extending downward and downward. The ridge rib 12 is an elongated body having a slightly triangular cross section, and an inner corner portion 14 of the ridge rib 12 connected to the plate body 11 on the left and right sides is an angular surface having an angling angle. . The connecting block 2 extends rearwardly from the plate body 11 of the arc plough 1 and is detachably mounted to the bottom of the implement machine. In use, when the agricultural implement mechanically walks in the field or the orchard, the arc rake 1 is shoveled into the soil, and the soil is ploughed with the movement of the implement, and the ridge rib 12 is used to Soil on the top surface of the plate body 11 Push to the sides.

However, since the plate body 11 of the arc rake 1 is a curved plate The sheet design is such that the slope of the tangent at each of the cuts from bottom to top is different. Therefore, when the lower end of the plate body 11 is worn due to use, it will become flat and close to a ground, which may cause the plow. Soil efficiency is not good, so it must be polished and refurbished frequently, which will reduce the efficiency of work and increase the manpower of maintenance.

Furthermore, the rib 12 has a slightly triangular cross section, and the left and right sides are The inner corner corner portions 14 between the side and the plate body 11 are also angular, so that stress concentration is likely to occur during use, thereby reducing the service life, and when the soil is ploughed, the soil is easily embedded in the rib rib 12 The left and right sides will affect the effect of pushing the soil to both sides, so it is necessary to clean and scrape frequently. It is inconvenient to use, so the design still needs to be improved.

Therefore, the object of the present invention is to provide a plowshare capable of maintaining the effect of the plow.

Thus, the new plowshare comprises a sloping plow and a connecting block. The sloping slab includes a plate body having an upper end and a lower end, the plate body being a flat plate extending obliquely forward and downward from the upper end toward the lower end. The connecting block extends rearward from the plate body of the inclined plough.

Another object of the present invention is to provide a plowshare having better structural strength and utility.

The plowshare of the present invention, the plate body further has a top surface, And a bottom surface, the inclined plough plate further comprising a ridge rib protruding longitudinally from a center of the top surface of the plate body, the ridge rib being an elongated body having a circular arc-shaped protuberance, and the ridge The angle between the left and right sides of the rib and the top surface of the plate body are rounded.

Other features and effects of the present invention will be apparent from the following description of the drawings, wherein: FIG. 1 is a perspective view of a conventional plowshare; FIG. 2 is a longitudinal cross-sectional view of the plowshare of FIG. 3 is a schematic transverse cross-sectional view of the plowshare of FIG. 1; FIG. 4 is a perspective view of an embodiment of the plowshare of the present invention; FIG. 5 is a longitudinal cross-sectional view of the embodiment; and FIG. 6 is one of the embodiments. A schematic cross-sectional view.

Referring to Figures 4, 5 and 6, an embodiment of the new type of plowshare is used for installation at the bottom of a farm machinery such as a cultivator, a boring machine, a ploughing machine, etc. (not shown). For the work of shovel, soil, ploughing, etc. The plowshare comprises a plywood 3 and a connecting block 4.

The sloping plate 3 includes a plate body 31, a ridge rib 32, and a piece of joint edge 33. The plate body 31 has an upper end 311, a lower end 312, a top surface 313, and a bottom surface 314. The plate body 31 is a flat plate piece that is gradually inclined forward and downward from the upper end 311 toward the lower end 312. The ridge rib 32 is a triangle with a slightly curved line The elongated strip body is longitudinally protruded from the center of the top surface 313 of the plate body 31, and extends from the upper end 311 to the lower end 312, and gradually becomes narrower and lower, and the left and right sides of the ridge rib 32 are An inner corner portion 34, which is connected to the top surface 313 of the plate body 31, respectively, is a rounded surface of a line and a slow arc. The joint edge 33 extends from the upper end 311 of the plate body 31 to the upper rear and has two perforations 331 spaced apart from each other. In this embodiment, the outline of the plate body 31 is substantially an isosceles triangle, the upper end 311 is a bottom edge of the isosceles triangle, and the lower end 312 is an apex of the isosceles triangle, and the ridge rib 32 is along The vertical bisector of the bottom edge of the isosceles triangle extends.

The connecting block 4 is extended by the plate body 31 of the inclined slab 3 Extendingly, and including a bottom bracket portion 41 connected to the bottom surface 314 of the plate body 31 and the bottom of the joint edge 33, and a connecting portion 42 extending rearward from the base bracket portion 41. The connecting section 42 has two front and rear spaced coupling holes 421. When assembled, the connecting block 4 is detachably mounted on the bottom of the implement machine. Since the connection relationship between the connecting block 4 and the implement machine is not the focus of the present invention, it will not be described in detail herein.

When used, when the farm implements machinery in the field or orchard, The sloping slab 3 of the ploughshare is shoveled into the soil, and the soil is ploughed together as the implement moves mechanically, and the top surface 313 of the slab body 31 is razed by the ridge rib 32. The soil is pushed to the sides.

In summary, the new type of plowshare is mainly by the plate body 31. It has a non-curved flat design, so that the slope from the bottom to the top is the same, that is, the angle between the lower end 312 and the ground that is worn after use is always the same, so that good plow can be maintained. Effect, extend the life Life, reduce the process of polishing and maintenance, not only can improve work efficiency, but also reduce the manpower of maintenance.

Furthermore, the new plowshare is also on the top surface of the plate body 31. The ridge rib 32 is longitudinally protruded from the center of the 313, and the ridge rib 32 is an elongated body having a surface arc convex, and the left and right sides and the inner corner portion 34 of the plate body 31 are respectively rounded, such that In addition, not only the stress concentration phenomenon can be eliminated, but also the structural strength of the plate body 31 can be further strengthened, and the service life is relatively extended. The most important thing is that when the soil is ploughed, the soil can be smoothly discharged to both sides, and it is difficult to embed the card. The left and right sides of the rib ribs 32 do not need to be cleaned and scraped frequently, so the soil is not subjected to the resistance of the soil when the soil is ploughed, and the utility model has better use effect, so the purpose of the present invention can be achieved.

However, the above is only an embodiment of the present invention, when The scope of the novel implementation is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the patent application and the contents of the patent specification are still within the scope of the present patent.
