The article presents the results of experimental research on the sorghum harvester, equipped with a threshing-separating device of the inertial-combing type for harvesting Donskoe-35 variety broom sorghum, work quality in the conditions of farms in the south-western zone of the Volgograd region of Russia. The heads losses change (Q_m) dependences on the combine speed (V_k) were determined: before the threshing chamber Q_m = – 0.079V_k ² + 0.426V_k + 0.01, behind the header Q_m = – 0.133V_k ³ + 1.2V_k ² – 3.567V_k + 4.1 and after the threshing chamber Q_m = 0.057V_k ² – 0.321V_k + 1.046, as well as grain losses (Q_z): behind the normalizer Q_z = 0,03V_k ³ – 0,241V_k ² + 0,686V_k – 0,083, by the Q_z = 0,004V_k ² + 0,025V_k + 0,28 and under-threshing in a head Q_z = 0,033V_k ² – 0,032V_k + 0,204. The sorghum harvester threshing growing heads by a threshing-separating device of an inertial-combing type showed a high quality of work: an increased level of heads losses was observed behind the header at combine speeds up to 1.5 m/s, but they did not exceed 2.6% at a combine speed of 0.5 m/s; while studying types of grain losses, the losses behind the normalizer reached the level of 0.6% at a combine speed of 3.0 m/s; the loss of grain behind the thresher and under-threshing in the head did not exceed 0.4%.

本文介绍了高粱收获机的实验研究结果，该机配备惯性梳理式脱粒分离装置，用于收获 Donskoe-35 品种扫帚高粱，在西南地区农场条件下的工作质量俄罗斯伏尔加格勒地区。确定了与联合速度 (V _k ) 相关的压头损失变化 (Q _m ) ：在脱粒室之前 Q _m = – 0.079V _k ² + 0.426V _k + 0.01，在割台后 Q _m = – 0.133V _k ³ + 1.2V _k ² – 3.567V _k + 4.1 及后脱粒室 Q _m = 0.057V _k ² – 0.321V _k + 1.046，以及晶粒损失 (Q _z )：归一化器后 Q _z = 0,03V _k ³ – 0,241V _k ² + 0,686V _k – 0,083，由 Q _z = 0,004V _k ² + 0,025V _k + 0,28 并在头部脱粒 Q _z = 0,033V _k ² – 0,032V _k+ 0,204。高粱收割机通过惯性梳理型脱粒分离装置脱粒生长的高粱显示出高质量的工作：在联合速度高达 1.5 m/s 时，在割台后面观察到高粱损失水平增加，但没有在 0.5 m/s 的联合速度下超过 2.6%；在研究谷物损失的类型时，在收割机速度为 3.0 m/s 时，正火机后面的损失达到 0.6% 的水平；脱粒机后面和头部脱粒不足的谷物损失不超过0.4%。
