T is in ntion cre a e to an improved landid io :earthwo k s implements such as moldboar and dis lows and particmarly to a rrangemen perm tt ng the sur a e of the "landside to "be selected to fit the characteristics of the s l- -l'n any plowing operation, there is a so-called side draft force of considerable magnitude vdirected against the furrow wall. To counteract such side draft. it has been common t employ a furrow wheel, which, when attached to the plow beam and in rolling contact with the furrow wall, greatly reduced the frictional losses encountered with any type of sliding landside, hence reduced the draft effort required in plow- The landside of a plow, whether a sliding or rolling type :is commonly constructed of metal and at least a portion of such 'landsides is alwaysin contact with the furrow wall. It is Well known that most inexpensive metallic materials do not have "high abrasion resistance, therefore, when a metallic landside is used in soils of an abrasive character, the rapid wear makes frequent replacement of the landside necessary. Again, when a metallic landside is used in extremely sticky :soil, such soil readily adheres to the surface of the landside. Even when employing a scraper in conjunction with the landside, particularly in the case of a rolling landside, the sticky soil will build up on the landside and around the "scraper to such an extent that freguen-t hand scouring and clearing is required, resulting in loss of time. It will be appreciated, however, -that a metallic landside is quite satisfactory in certain other types of soils.
Accordingly, it is an object of this invention to provide an improved landside for plows having a plurality of surfaces selectively adapted to the characteristics of the soil'being plowed.
Another object of this invention is to provide an improved landside for plows characterized by the utilization of a replaceable cover for a landside toproduce an optimum surface material on the jahdside for the "particular type of soil being mow d- AnotherObject fthis invention is to provide a replaceable cover for the rolling landside of a nioldboardplow which has a surface resistant to the adherence of sticky soils.
gtillanother obiectof thisinvention is toprovide a resilient coating for a rolling "landside which is resistant to both abrasive and sticky so ls- A further bject of this nvention is to p ovide a resilient cover for a rolling landside of a moldboard plow which is inexpensively manu- 4 faotured and whioh greatly increases the life of the rolling landside.
The .specificrnature of this inv nt n, as well as ther ob ects and advanta es th re f, -will b come apparent to those skilled in the art from the. follow n d tailed descri n taken "in conjunction with the attached sheets of drawings on which, "by way of preferred example only, is illustrated two embodiments of this invention.
On the raw n Figure 1 is a persnect'ivecrear end view of a moldboard plow showing the rolling landslide mounted behind the plow bottom.
jEigurexZ is a cross sectional view taken along the plane 2+2 of Figure l.
TFigure '3 is an enlargeddetail view showing, a modification of the invention.
As shown on the drawings:
There are many types of landsi'de yior plows to which this 'inventionmay be adapted. All of the 'landsides are utilized for the same purpose namely, to counteract "thexside draft-introduced when plowing. It, therefore, follows that all landsides are subjected more or less to the same amount of wear from erosion and-to difficulties encountered in sticky sci-1s. Inasmuch as all lands'ides perform substantially the same function, there will "be described herein only a preferred application of this invention as applied to rolling "landsides or furrow wheels. Accordingly, there :is shown ,in Figure l a moldboard plow bottom of conventional construction secured to a plow beam ll. Themoldboard l2 of plow bottom I0 is braced-relative to plow beam II by a bracket [3, A s,ubstan-tially L-shaped bracket l4 is-mounted on'the lower end of plow beam il vand such bracket is provided with a horizontalrearwardlyextending'arm l5. Aboriv zonta'lly disposed bolt 16 is inserted through a transverse hole I"! provided adjacent the end of arm 15 and a hub 18 is rotatably mounted on bolt 15, A nut 'lflscrewed onto the threaded end portion of bolt 15 and resting within a counterbore *l'la rotatably secures hub 18 on bolt 16.
An jintegral substantially sonically shaped flange ".29 jisprovided on-the left end of hub 18 as shown in tIEfigure 2, such flange being provided to support a rolling ,ilandside -'2=|. 'Landside 21 of generally conical, --somewhat-saucer-l-ike, configuration is mounted on flange 20- with the'interior bottom portion of suchxlandside being contiguous to such flange. A plurality of bolts '22 insertable through suitable transverse apertures provided respectively in ;landside 12,! and dense 2U secure rolling landside'"2l 'tohub '18.
A cover 23 of a resilient material, preferably a suitable grade of rubber, is shaped to surround the exterior conical surface of rolling landside 2|. Cover 23 is provided with an inturned peripheral edge 24 and an integral bead 25 is formed on inturned edge 24. Bead 25 is of somewhat smaller diameter than the edge of rolling landside 2| so that considerable force must be exerted to assemble such bead over the peripheral edge of landside 2|. When in position however the bead 25 will maintain the cover in tension so that such cover will fit tightly on the exterior surface of landside 2|. An integral bead Zla is preferably provided on the edge of rolling landside 2| which cooperates with bead 25 to further assist in securing the cover to landside 2|.
In Figure 3 there is shown an enlarged fragmentary detail view of the portion of the furrow wheel illustrating a modified form of this invention. In this modification the exterior surface of furrow wheel 2| or that surface of the landside which abuts the furrow wall, is covered by a ply of rubber-like material 28, bonded to such surface by any of the well-known processes. Alternatively, the furrow wall engaging surface of landside 2| may be coated with a rubber-like material which is sprayed on. In any case, it is preferable for the layer or coating of rubber-like material to have a substantial thickness, thus not only will longer life be provided but the action of a thicker layer of a rubber coated surface resists sticky soils to a much greater extent.
In plowing with plow bottom I!) as shown in Figure 1, the share cuts the furrow slice 28 and the moldboard turns such slice over. Formation of the furrow slice leaves a furrow wall 21 against which the rolling landside comes in contact. As the rubber covered surface of the rolling landside contacts the furrow wall, the abrasive action of the soil will be directed against the rubber material. It is well known, however, that rubber is highly resistant to the erosive action of most abrasive materials and, accordingly, will stand up in a superior manner to that of steel. The inherent resiliency of the rubber faced rolling landside very effectively prevents the'adherence of sticky soils to such facing When the rolling landside is contacting the furrow wall during the operation of the plow, the rubber facing or coating on such furrow wall is constantly moving under stress from the compressive forces acting against such facing. As the rubber is very resilient, the rubber facing then moves slightly in several directions at once, whereby the sticky soils will in effect be shaken off.
With the modification of Figures 1 and 2, the rubber cover is readily removed when worn or for plowing in non-sticky, non-abrasive soil by forcing the bead 25 over the peripheral edge 2|a of the rolling landside. A new cover may be as quickly assembled to the rolling landside by reversing the above procedure. In the modification of Figure 3, the old rubber material may be removed by scraping and a new coating applied in the manner utilized for applying the original coat. Thusthe furrow wheel may be cheaply and quickly furnished with a rubber coating which will greatly increase the life of the rolling landside in addition to providing the advantageous features previously pointed out.
It will appear from the description above that there is here provided a cover or coating of a rubber-like material for a landside or furrow wheel which is highly resistant to abrasive soil, thereby greatly increasing the life of such landside. The inherent resiliency of the rubber faced landside prevents sticky soils from adhering to the surface of such cover hence the need of a scraper for the furrow wheel is eliminated.
With the detachable cover construction, the surface of the landside may be conveniently changed to best conform to the characteristics of I the soil to be plowed.
It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
I claim:
