DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0023] Embodiment 1:

[0024] like Figure 1-6As shown, the portable spreader with an adjustable discharge port of the utility model comprises an outer shell 6, a spreading through hole 8 and a receiving groove 18 are respectively provided at the bottom of the outer shell 6, a motor 7 is symmetrically fixedly installed on the inner side of the receiving groove 18, and the output shaft of each motor 7 is fixedly connected to the rotating shaft 13, a connecting through hole 17 is provided on the rear surface of the outer shell 6, a connecting block 9 is inserted into the interior of the connecting through hole 17, and two hair rollers 10 are rotatably connected to the interior of the connecting block 9, one end of each hair roller 10 is fixedly connected to a plug-in column 11 connected to the receiving groove 18, and one end of the plug-in column 11 is plugged into the rotating shaft 13, a connecting shaft 15 is rotatably connected to the rear surface of the outer shell 6, and a stopper 16 in contact with the connecting block 9 is sleeved on the outer side of the connecting shaft 15.

[0025] like Figure 2-3 As shown, the wool roller 10 is located inside the spreading through hole 8, and the longitudinal section of the plug-in column 11 is a square structure.

[0026] During implementation, two hair rollers 10 are arranged inside the sowing through hole 8. By starting the two motors 7, the rotating shaft 13 connected to the output shaft drives the hair roller 10 connected through the plug-in column 11 to rotate, so as to control the seed feeding speed. Moreover, by rotating the stopper 16, it is freed from the restriction on the position of the connecting block 9, so that the connecting block 9 can be moved out of the inside of the connecting through hole 17. At the same time, since the hair roller 10 and the rotating shaft 13 are plugged in with the plug-in column 11, it is convenient to disassemble the hair roller 10 and replace it, which solves the technical problem that the discharge speed of the discharge port of the portable spreader is inconvenient to adjust according to personal needs and different seeds, resulting in poor adaptability and reduced practicality.

[0027] Embodiment 2:

[0028] like Figure 1-6 As shown, on the basis of embodiment 1, the utility model provides a technical solution: a seed storage box 1 is arranged inside the outer shell 6, a handle 4 is fixedly installed on the upper surface of the seed storage box 1, a power supply unit 3 is fixedly installed on one side of the seed storage box 1, and a feed hopper 2 is fixedly connected to the other side of the seed storage box 1, movable grooves 14 are provided on the front and rear surfaces of the inner cavity of the outer shell 6, a movable block 12 is slidably connected inside the movable groove 14, the movable block 12 is fixedly connected to the seed storage box 1, a screw rod 19 is rotatably connected to the inner side of the rear movable groove 14, the screw rod 19 is screwed to the movable block 12, and the upper end of the screw rod 19 passes through the outer shell 6 and is fixedly connected to the operating block 5.

[0029] During implementation, the seed storage box 1 and the outer shell 6 are movably connected by a movable block 12 and a movable groove 14. By rotating the operating block 5, the screw rod 19 connected thereto is driven to rotate, thereby controlling the outer movable block 12 to drive the seed storage box 1 to a certain height, thereby exposing the hair roller 10, thereby achieving the effect of checking the wear of the hair roller 10 and facilitating timely replacement.

[0030] The outer shell 6 of the present technical solution is provided with a control switch (not shown in the figure). When in use, firstly, the seeds are added into the seed storage box 1 through the feed hopper 2, then the handle 4 is held, and the motor 7 is started to drive the rotating shaft 13 connected to its output shaft to drive the hair roller 10 connected through the plug-in column 11 to rotate, so that the seeds fall from the gap between the two hair rollers 10, and the feeding speed can be adjusted by controlling the rotation speed of the hair roller 10. When the hair roller 10 needs to be disassembled, firstly the block 16 is rotated to a horizontal state with the connecting shaft 15 as the center, and then the connecting block 9 is moved out of the connecting through hole 17, so that the hair roller 10 is pulled out from the inside of the outer shell 6, and at the same time, the plug-in column 11 connected to the hair roller 10 is separated from the inside of the rotating shaft 13.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
