Abstract

The tire includes an outer shell formed from a first resilient material and an inner core formed from a second resilient material. The first resilient material is harder than the second resilient material.
Description
- The present invention relates to agricultural seeders, and, more particularly, to furrow opener arrangements for such seeders.
- An agricultural seeder such as a row crop planter or grain drill places seeds at a desired depth within a plurality of parallel seed trenches formed in soil. In the case of a row crop planter, a plurality of row crop units are typically ground driven using wheels, shafts, sprockets, transfer cases, chains and the like. Each row crop unit has a frame which is moveably coupled with a tool bar. The frame may carry a main seed hopper, herbicide hopper, insecticide hopper, furrow opener arrangement, furrow closer arrangement, etc.
- One type of furrow opener arrangement uses a depth gauge wheel which is placed adjacent to the leading edge of a single disc opener assembly including a seed tube on the trailing side of the disc. The gauge wheel provides depth adjustment, cleans the leading face of the disc, and limits soil lifting and throw adjacent the disc opener.
- Gauge wheels are typically manufactured with a rubber tire which is mounted to the outer periphery of a multi-piece, clam shell type rim. The outer radial periphery of each clam shell half of the rim is flared and the tire is sandwiched therebetween. Fasteners such as bolts or rivets are then used to bolt the clam shell halves of the rim together.
- A gauge wheel as described above is part of an effective furrow opener arrangement. However, the multi-piece clam shell arrangement makes the gauge wheel more time consuming and costly to manufacture. Moreover, the rubber tire compromises between wear resistance and shock absorbance. If the rubber is too hard, it will not absorb shock sufficiently when traveling over uneven or rough ground. If the rubber is too soft, it will wear prematurely when traveling over stubbly fodder present in no-till field environments.
- What is needed in the art is a furrow opener arrangement with a gauge wheel which is easier and cheaper to manufacture, has good wear characteristics, and good shock absorbing characteristics.
- The invention in one form is directed to a gauge wheel for an agricultural implement, including a rim having an outer periphery and a tire mounted to the outer periphery. The tire includes an outer shell formed from a first resilient material and an inner core formed from a second resilient material. The first resilient material is harder than the second resilient material.
- The invention in another form is directed to an agricultural implement, including a tool bar and at least one row unit carried by the tool bar. Each row unit includes a furrow opener arrangement with a gauge wheel. The gauge wheel includes a rim with an outer periphery and a tire mounted to the outer periphery. The tire includes an outer shell formed from a first resilient material and an inner core formed from a second resilient material. The first resilient material is harder than the second resilient material.
- The invention in yet another form is directed to a wheel including a rim having an outer periphery, and a tire mounted to the outer periphery. The tire includes an outer shell formed from a first resilient material and an inner core formed from a second resilient material. The first resilient material is harder than the second resilient material.

For each embodiment, it is to be understood that the gauge wheel includes a tire with an inner core and an outer shell, each made from different resilient materials, with the inner core being softer than the outer shell. The construction of the tire in this manner provides good wear, good shock absorbance, and good mud shedding capabilities.
- Referring now to
FIG. 4 , there is shown another embodiment of agauge wheel 60 of the present invention.Tire 62 is constructed generally the same as tire 28 shown inFIGS. 1-3 . However, rim 64 is constructed as a one piece molded part with asteel bushing 66 for retaining a bearing associated with an axle shaft.Rim 64 is thus constructed as an integral and monolithic rim which carriestire 62 andsteel bushing 66.Rim 64 is preferably constructed as a rigid, molded plastic part, but could also be constructed from machined or molded metal such as aluminum. - Referring now to
FIGS. 5 and 6 , there is shown another embodiment of agauge wheel 70 of the present invention.Gauge wheel 70 includes atire 72 which is mounted to arim 74.Tire 72 includes aninner core 76 and anouter shell 78, as do gaugewheels FIGS. 1-3 and 4 above. However,tire 72 is not held in place relative torim 74 using keying betweeninner core 76 and theouter periphery 80 ofrim 74. Referring toFIG. 5 , it is evident that theouter periphery 80 ofrim 74 is generally flat in the area adjacent toinner core 76. On the other hand, it is also evident thatouter periphery 80 has a stepped shoulder on the left side where it engages with and keys toouter shell 78 oftire 72. - As with the embodiment of
gauge wheel 60 shown inFIG. 4 ,gauge wheel 70 also has a one piece rim with ahub 82, radially extendingweb 84, andouter periphery 80 which are integrally and monolithically constructed together. Asteel bushing 86 carries abearing 88 andaxle shaft 90, which in turn is mounted to anarm 92 mounted to the frame of the row crop unit.Web 84 also includes curved, axially extending reinforcingribs 94 which terminate along an outer edge ofouter periphery 80. - Referring now to

FIG. 8 ,gauge wheel 120 can be formed with aninner core 130 which is partially hollow or cored out. For example, a portion of the cross sectional area ofinner core 130 can be optionally cored out as shown by dashedline 136. It will be appreciated that the cored out area has an annular shape extending aroundgauge wheel 120, withininner core 130. Of course, any of the inner cores shown in the other embodiments can also be partially cored out. Such a cored out area within the inner core may provide desirable load damping characteristics and mud shedding. - In the embodiments shown, the gauge wheel is used in conjunction with an agricultural seeder in the form of a row crop planter. However, it is also to be understood that the gauge wheel may also be used for other applications, such as a wheel for a fertilizer applicator, mower, etc.
