    • A square baler is disclosed which comprises a baling chamber, a plunger (16) reciprocable at one end of the baling chamber, a pre-compression chamber (18) within which charges of crop are amassed and pre-compressed by a rotor (32) prior to transfer into the baling chamber, and a pickup roller (30) having radially projecting tines for picking up crop from the ground and advancing the crop to the rotor. In the invention, a torque sensor (34) is connected to at least one tine bar of the pickup roller to produce an electrical output signal indicative of the torque experienced by the tine bar, and a processing circuit (46) is operative to estimate the rate of crop flow into the pre- compression chamber by analysing the electrical output of the torque sensor only at times when the position of the tines lies within a predetermined angular position of the pickup roller.
    • 公开了一种方形打捆机,其包括打包室,可在打包室的一端往复运动的柱塞(16),预压缩室(18),在该预压缩室(18)内收集作物并由转子(32)预压缩, 在转移到打包室之前,以及具有径向突出的齿的拾取辊(30),用于从地面拾取作物并将作物推进到转子。 在本发明中,扭矩传感器(34)连接到拾取辊的至少一个齿条,以产生指示由齿杆经历的转矩的电输出信号,并且处理电路(46)可用于估计 只有当齿的位置位于拾取辊的预定角度位置时,才通过分析扭矩传感器的电输出来将作物流入预压缩室。
