Title
(EN) AGRICULTURAL PLANT PROTECTION MACHINE AND DIAPHRAGM PUMP THEREOF
(FR) MACHINE AGRICOLE DE PROTECTION DES PLANTES ET POMPE À MEMBRANE ASSOCIÉE
(ZH) 农业植保机及其隔膜泵
Abstract
(EN)
An agricultural plant protection machine and a diaphragm pump thereof. The diaphragm pump (400) comprises: a pump body (1), provided with an accommodating cavity; a pump cover (2) covered on the pump body (1); a diaphragm (3) provided in the accommodating cavity and matching the pump cover, so that the diaphragm and the pump cover enclose a cavity (4); and a driving mechanism (5) provided in the accommodating cavity and comprising a push rod (51), a coil assembly (52), and an elastic reset element (53), the push rod (51) being connected to the diaphragm and connected to the elastic reset element; when the coil assembly is alternately powered on and powered off, the push rod can do reciprocating linear motion to drive the diaphragm to reciprocate with respect to the pump cover such that the cavity is reduced or increased; when the coil assembly is powered on, the push rod moves forwards under the action of magnetic attraction force of the coil assembly; when the coil assembly is powered off, the push rod moves reversely under the action of elastic force of the elastic reset element; the forward direction and the reverse direction are opposite.
(FR)
La présente invention concerne une machine agricole de protection des plantes et une pompe à membrane associée. La pompe à membrane (400) comprend : un corps de pompe (1) doté d'une cavité de réception ; un couvercle de pompe (2) recouvert sur le corps de pompe (1) ; une membrane (3) disposée dans la cavité de réception et correspondant au couvercle de pompe, de sorte que la membrane et le couvercle de pompe entourent une cavité (4) ; et un mécanisme d'entraînement (5) disposé dans la cavité de réception et comprenant une tige de poussée (51), un ensemble bobine (52) et un élément de réinitialisation élastique (53), la tige de poussée (51) étant raccordée à la membrane et raccordée à l'élément de réinitialisation élastique ; lorsque l'ensemble bobine est mis sous tension et hors tension de façon alternée, la tige de poussée peut réaliser un mouvement linéaire de va-et-vient pour amener la membrane à réaliser un mouvement de va-et-vient par rapport au couvercle de pompe de sorte que la cavité est réduite ou augmentée ; lorsque l'ensemble bobine est mis sous tension, la tige de poussée se déplace vers l'avant sous l'action d'une force d'attraction magnétique de l'ensemble bobine ; lorsque l'ensemble bobine est mis hors tension, la tige de poussée se déplace en sens inverse sous l'action d'une force élastique de l'élément de réinitialisation élastique ; la direction avant et la direction inverse sont opposées.

一种农业植保机及其隔膜泵,所述隔膜泵(400)包括:泵体(1),设有收容腔;盖设在泵体上的泵盖(2);设于收容腔内的隔膜(3),隔膜与泵盖相配合,以使隔膜与泵盖包围形成腔体(4);以及设于收容腔内的驱动机构(5),驱动机构包括推杆(51)、线圈组件(52)和弹性复位件(53),推杆与隔膜相连,并与弹性复位件相连;当线圈组件交替地进行通电和断电时,推杆能够做往复直线运动,以带动隔膜相对泵盖往复运动而使得腔体减小或增大;其中,当线圈组件通电时,推杆在线圈组件的磁性吸引力作用下做正向运动;当线圈组件断电时,推杆在弹性复位件的弹性力作用下做反向运动,正向与反向为相反的两个方向。
