专利汇可以提供Mobile vibratory cable plow专利检索,专利查询,专利分析的服务。并且A mobile trailer having a pair of rearwardly extending, spaced apart arms pivotally attached thereto with an elongated plow blade affixed therebetween in a downwardly extending position. An eccentric-type vibrator is also mounted between the arms for rotation about an axis parallel with the arms to vibrate the plow blade in a direction transverse to the direction of movement of the trailer and blade. The trailer further has means for mounting a spool of conduit and a channel is formed along the trailing edge of the plow blade for positioning the conduit at the bottom of a trench formed by the plow blade.,下面是Mobile vibratory cable plow专利的具体信息内容。

1. A vibratory cable laying plow, comprising: a. a relatively rigid, towable frame having at least two laterally spaced, ground-engaging wheels; b. a pair of elongated, flat, plate-like arms having front and rear ends, said front ends being pivotally attached to the frame, said arms each having a vertically oriented transverse axis and a rearwardly extending longitudinal axis; c. means mounting an elongated plow blade between said rear ends, said blade having cable receiving channel means positioned along a trailing edge thereof; d. means connected between said frame and said pair of arms for selectively pivoting said arms to move said plow blade into and out of engagement with the ground; e. vibratory means connected to said plow blade for vibrating said plow blade in a direction transverse to the direction of plowing movements, said arms being attached to said frame by means including resilient vibration isolators to substantially isolate said frame from saId vibration; and f. a cable reel rotatably mounted on said frame in position to supply and unreel a cable extending therefrom through said cable receiving channel means.
2. The apparatus of claim 1 wherein the means connected between said frame and said arms includes first and second elongated links each having one end pivotally attached together and the opposite ends pivotally attached to the frame and one of said arms, and at least one hydraulic cylinder having one end attached to the attached togetHer ends and the other end attached to the frame for moving the attached together ends to produce pivotal raising and lowering of the arms.
3. The apparatus of claim 1 wherein said frame includes a transversely extending spindle journalled at its opposite ends in a pair of side frame members, wherein a pair of vibration isolators are mounted on said spindle, and a pair of mounting sleeves are mounted on said vibration isolators, said arms being attached to said sleeves.
4. A vibratory cable laying plow, comprising: a. a mobile frame in the form of a towable trailer having at least two laterally spaced, ground-engaging wheels; b. a pair of transversely spaced, elongated, relatively thin metal plates positioned between said wheels, each plate having a front end pivotally attached to the frame and a rear end supporting a mounting bar affixed therebetween, said plates being positioned in generally vertical planes; c. an elongated plow blade mounted on said mounting bar and constructed for movement through the ground in a generally upright position, said blade having cable receiving channel means positioned along a trailing edge thereof; d. means connected between said frame and said pair of metal plates for selectively pivoting said plates to move said plow blade into and out of engagement with the ground; e. vibratory means attached to said mounting bar for vibrating said plow blade in a direction transverse to the direction of plowing movements, said elongated metal plates being secured to said frame by means acting to substantially isolate said frame from said vibration; and f. a cable reel rotatably mounted on said frame in position to supply and unreel a cable extending therefrom through said cable receiving channel means.
5. The apparatus of claim 4 wherein said frame is generally U-shaped with the central portion thereof opening rearwardly, wherein a transversely extending spindle is journalled to said frame adjacent a front end thereof, said plates being connected to said spindle.
6. The apparatus of claim 5 wherein a pair of resilient tubular vibration isolators are mounted over said spindle, and wherein a pair of mounting sleeves are mounted over said vibration isolators, said plates being connected to said sleeves.
