Abstract
A machine for pulling weeds from rows having crops, as sugar beets. The machine has a transverse tool bar carrying a hitch. The hitch connects the tool bar to a tractor. A plurality of weed-pulling units are mounted on the tool bar. Each weed pulling unit has a pair of engaging pneumatic tires that are driven in opposite directions with a hydraulic motor. A pair of gauge and guide wheels connected to the tool bar locate the tool bar and weed pulling wheels above the surface of the ground so that the engaging rotating pneumatic tires will pull weeds from the rows of crops.
Claims24
An apparatus for pulling weeds and the like from a row of crops and weeds comprising:
- a transverse tool bar mountable on a draft vehicle, a weed pulling unit attached to the tool bar, said unit having a housing and generally rearwardly directed spaced members attached to the housing, first shaft means rotatably mounted on one of the members, second shaft means rotatably mounted on the other of the members, first wheel means attached to the first shaft means, second wheel means attached to the second shaft means, said first and second wheel means being rotatable about axes located in planes extended generally parallel to the row, each of said wheel means having surfaces that engage each other and adapted to engage the weeds in the row and pull the weeds out of the ground, power transmission means to drive said first and second wheel means in opposite directions whereby said weeds between said first and second wheel means are pulled from the ground, said power transmission means being located in said housing and drivably connected to the first shaft means and second shaft means to rotate the first and second shaft means in opposite directions, and power means operable to supply power to the power transmission means.
An apparatus for pulling weeds and the like from crops comprising:
- a transverse tool bar, hitch means connected to the tool bar for mounting the tool bar on a draft vehicle, a weed pulling unit attached to the tool bar, said unit having rearwardly directed spaced members, a first shaft means rotatably mounted on one of the members, a second shaft rotatably mounted on the other of the members, first wheel means attached to the first shaft means and second wheel means attached to the second shaft means, said first and second wheel means being rotatable about generally longitudinal axes, each of said wheel means having a surface engageable with the other wheel means and adapted to engage the weeds in the row and pull the weeds out of the ground, drive means to apply a rotating force directly to said first shaft means and said second shaft means thereby rotating said first and second wheel means in opposite directions whereby said weeds between said first and second wheel means are pulled from the ground, and means mounting the weed pulling unit to the tool bar, said mounting means including means which permit the vertical adjustment of the weed pulling means relative to the tool bar.
