When the discharge pipe 12 swings to the leftmost limit position along with the first circular plate 8, the annular plate 25 contacts with the first friction plate 34 on the upper side of the annular plate, the annular plate 25 starts to rotate due to friction force, the annular plate 25 is in threaded connection with the corresponding outer side wall of the discharge pipe 12, the annular plate 25 continuously moves along the horizontal pipe of the discharge pipe 12 in the rotating process, the moving direction is the direction away from the pipe orifice of the discharge pipe 12, the side wall of the second sleeve 47 is in rotational connection with the corresponding side wall of the annular plate 25, the second sleeve 47 moves towards the direction away from the pipe orifice of the discharge pipe 12 under the driving of the annular plate 25, so that the pull rod 42 is pulled towards the inner end, the outer end of the movably arranged sector plate 41 is hinged with the corresponding pull rod 42, the movably arranged sector plate 41 starts to rotate outwards under the pulling force of the sector plate 42 to open, and fertilizer is scattered from the opening position of the movably arranged, the state that the hand grabs the fertilizer and waves is simulated, the uniform fertilizer volatilization is realized, and the operation is convenient and rapid; in the process that the discharge pipe 12 swings rightwards from the leftmost limit position, the annular plate 25 is contacted and rubbed with the first friction plate 34 again, the annular plate 25 rotates reversely, the second sleeve 47 is driven to move towards the pipe orifice of the discharge pipe 12, the sprinkling device is also closed under the pushing of the second sleeve 47, meanwhile, the elastic force provided by the torsion spring can also help the sector plate to rotate inwards and close, so that the pipe orifice of the discharge pipe 12 is shielded again, the pipe orifice is closed, the fertilizer cannot be sprinkled out of the discharge pipe 12 at the moment, and the waste is avoided; when the discharge pipe 12 moves to the right limit position, the annular plate 25 contacts with the second friction plate 35 on the lower side of the discharge pipe, and the annular plate 25 starts to rotate so as to drive the sprinkling device to be opened and spill the fertilizer again, so that the fertilizer is sprinkled when the discharge pipe 12 moves to the swing limit position, the sprinkling uniformity is improved, and the fertilizer is effectively prevented from being sprinkled on the road surface to cause waste; fertilizer can spill out when discharging pipe 12 swings to swing amplitude extreme position, therefore the user can change the swing range of discharging pipe 12 according to the concrete planting condition of crop, and then control fertilizer's the position of spilling out, convenient and fast, simultaneously because sector plate 41 is annular evenly distributed, the degree of consistency is higher when fertilizer waves out, is favorable to the fertilization growth of crop more.

Furthermore, as shown in the figure, the bottom of the horizontal plate 19 in this embodiment corresponds to the positions of the first friction plate 34 and the second friction plate 35, and is fixedly connected with a vertical rod 44, the side wall of the vertical rod 44 is fixedly connected with a second electric telescopic rod 45 with a movable rod facing inward, and the end of the movable rod of the second electric telescopic rod 45 is fixedly connected with the side wall of the corresponding friction plate. When the user need use this device to fertilize the greenhouse vegetable of different row spacing, can change the swing range of discharging pipe 12 through the front and back position of adjustment electric slider 22, because the change of discharging pipe 12 swing range, the ejection of compact position of discharging pipe 12 also correspondingly makes the change, when greenhouse vegetable's planting row spacing is less promptly, the user can control the distance that first friction plate 34 and second friction plate 35 are reduced to the extension of second electric telescopic handle 45 according to particular case, thereby control sector plate 41's open time, and then control discharging pipe 12's ejection of compact position, and is convenient and effective, the stability and the reliability of this device have been improved.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
