专利汇可以提供Apparatus for laying underground cable专利检索，专利查询，专利分析的服务。并且The invention relates to a vibrating plow blade assembly employing laterally protruding auxiliary blades for cultivating soil beneath the ground surface to form an underground cable channel having non-parallel side walls which exert compacting forces on the cultivated soil about a buried cable in response to compaction activity. A thin coulter blade is used to neatly sever the ground surface to maintain surface disturbance at a minimum.，下面是Apparatus for laying underground cable专利的具体信息内容。
1. Apparatus for laying cable in the ground at a distance below the surface of the ground, comprising in combination, a cable plow assembly disposed beneath the surface of the ground, means operatively connected to said cable plow assembly for advancing said cable plow assembly, means associated with said cable plow assembly for imparting vibrator motion thereto, said cable plow assembly including, coulter blade means for severing the surface without significantly disrupting the surface of the ground, a plow blade means including a forward cutting member and laterally protruding auxiliary blades, said auxiliary blades positioned so as to cultivate the soil to produce a channel below the surface of the ground, wherein said auxiliary blades comprise, a first pair of auxiliary blades positioned near the bottom of said plow blade means, and extending laterally from either side of said plow blade means, and a second pair of larger auxiliary blades positioned some distance above said first pair of auxiliary blades and extending laterally from either side of said plow blade, said first and second pairs of auxiliary blades being angularly disposed so as to cultivate the soil in such a manner as to produce a channel which is substantially heart-shaped in cross section, means for introducing cable into said channel, and means for applying soil compacting forces to the ground surface above said channel, said side walls of said channel transmitting said compacting forces to the cultivated soil to enhance compaction of the cultivated soil about the cable.
2. Apparatus for laying cable in the ground at a distance below the surface of the ground, comprising in combination, a cable plow assembly disposed beneath the surface of the ground, means operatively connected to said cable plow assembly for advancing said cable plow assembly, means associated with said cable plow assembly for imparting vibratory motion thereto, said cable plow assembly including, coulter blade means for severing the surface without significantly disrupting the surface of the ground, a plow blade means including a forward cutting member and laterally protruding auxiliary blades, said auxiliary blades positioned so as to cultivate the soil to produce a channel below the surface of the ground, the sides of said channel being substantially non-parallel, means for introducing cable into said channel, a compactor blade attached to said plow blade means and extending rearwardly from the rear, bottom portion of said plow blade means, said compactor blade riding in the channel above said cable to compact the cultivated soil about the cable in response to the vibratory motion of said cable plow assembly, and means for applying soil compacting forces to the ground surface above said channel, said side walls of said channel transmitting said compacting forces to the cultivated soil to enhance compaction of the cultivated soil about the cable.
3. Apparatus as claimed in claim 2 wherein said forward cutting member of said plow blade slopes downwardly and forwardly to facilitate the penetration of the soil and to clear the path of the cable plow assembly by forcing obstacles such as rocks and branches to the surface in response to the vibratory motion of said cable plow assembly.
4. Apparatus as claimed in claim 2 including a sand ejector assembly for supplying sand into the channel to enhance the compaction of the soil about the cable.
5. A method for laying underground cable utilizing a plow blade assembly positioned beneath the surface of the ground, including the steps of, severing the surface of the ground without significantly disrupting the surface, cultivating the soil beneath the surface of the ground in response to vibratory motion of the plow blade assembly to produce a cable channel having side walls of undisturbed soil extending intermediate said ground surface and the cultivated soil and forming a cable channel which is substantiallY symmetrical for transmitting surface applied compacting forces to the cultivated soil to enhance compaction of the cultivated soil about the cable, feeding cable into said cable channel, and applying compacting forces to the surface of the ground above said channel.
6. A method as claimed in claim 5 including the step of feeding sand into said cable channel to improve compaction of the cultivated soil about said cable.
7. Apparatus as claimed in claim 2 wherein said means for introducing cable into said channel comprises a cable feeding means associated with said plow blade means for feeding cable through the bottom of said plow blade means into said channel.
8. Apparatus for laying cable in the ground at a distance below the surface of the ground, comprising in combination, a cable plow assembly disposed beneath the surface of the ground, means operatively connected to said cable plow assembly for advancing said cable plow assembly, means associated with said cable plow assembly for imparting vibratory motion thereto, said cable plow assembly including, coulter blade means for severing the surface without significantly disrupting the surface of the ground, a plow blade means including a forward cutting member and laterally protruding auxiliary blades, said auxiliary blades positioned so as to cultivate the soil to produce a channel below the surface of the ground, wherein said auxiliary blades comprise, a first pair of auxiliary blades positioned near the bottom of said plow blade means and extending laterally from either side of said plow blade means, and a second pair of smaller auxiliary blades positioned some distance above said first pair of auxiliary blades and extending laterally from either side of said plow blade, said first and second pairs of auxiliary blades being angularly disposed so as to cultivate the soil in such a manner as to produce a channel which is substantially larger at the bottom than at the top, means for introducing cable into said channel, and means for applying soil compacting forces to the ground surface above said channel, said side walls of said channel transmitting said compacting forces to the cultivated soil to enhance compaction of the cultivated soil about the cable.
