Control method and device of grabbing hopper and grabbing machine
According to the control method and device of the grabbing hopper and the grabbing machine, the closing state of the grabbing hopper is obtained according to the closing time and the lifting height of the grabbing hopper, and when the grabbing hopper enters the completely-closed state and the output pressure of a plunger pump is larger than a first pressure threshold value, the grabbing hopper is closed; the plunger pump is controlled to output at constant power, the flow demand of the grabbing hopper is calculated according to the output pressure of the plunger pump so as to reduce the flow demand of the grabbing hopper, then the flow demand of other execution components is calculated according to the pilot pressure signal, and finally the flow demand of the grabbing hopper and the flow demand of other execution components are calculated. And the output flow of the plunger pump is obtained through calculation, so that overflow of the grabbing hopper and throttling loss of other execution components are reduced, and the fuel economy of the grabbing machine is improved.
本申请公开了一种抓料斗的控制方法、装置及抓料机，通过根据抓料斗的闭合时间和起升高度获知抓料斗的闭合状态，并且在抓料斗进入完全闭合状态且柱塞泵的输出压力大于第一压力阈值时，控制柱塞泵恒功率输出且根据柱塞泵的输出压力计算抓料斗的流量需求以降低抓料斗的流量需求，然后根据先导压力信号计算其他执行部件的流量需求，最后根据抓料斗的流量需求和其他执行部件的流量需求，计算得到柱塞泵的输出流量，以降低抓料斗溢流和其他执行部件的节流损耗，从而提高抓料机的燃油经济性。
