[0048] Meanwhile, a motor bracket 211 is mounted on the motor 21, and the motor 21 bracket is fixedly installed on the outer side wall of the mounting box 1.
[0049] During the working process, one side of the box door 23 can be rotatably opened, or both sides of the box door 23 can be synchronously opened, and the angle of the box door 23 turning downward during the process of the box door 23 being controlled to be opened is controlled, so as to control the size of the gap between the box doors 23 and the falling speed of the leaflets.
[0050] Specifically, the belt wheel 22 is driven to rotate by the motor 21, and the box door 23 is controlled to be opened under the rotation of the belt wheel 22, so that the opening state of the box door 23 can be controlled by controlling the working state of the motor 21.
[0051] In the actual working process, a protective cover is installed on the outer side wall of the mounting box 1 in the conventional way disclosed in the prior art, and the motor 21, the belt wheel 22, and the driving belt wheel 24 are covered.
[0052] Embodiment 2
[0053] As Figs. 1-6As shown, the embodiment is based on the structure of example 1, in order to further disperse the leaflets, to realize the increase of leaflets falling coverage, the above-mentioned leaflet scattering mechanism also includes a leaflet carrier arranged in the mounting box 1, the leaflet carrier includes a plurality of rectangular structure support seats 3, the support seat 3 is hingedly arranged.
[0054] Specifically, the mounting box 1 is provided with left and right symmetrical leaflet carriers.
[0055] Each leaflet carrier is hingedly arranged with a plurality of support seats 3 from top to bottom, and the stacked leaflets are supported and placed on the support seat 3.
[0056] Specifically, the leaflet carrier also includes a hinge strip frame 41 arranged at intervals between the front and rear sides, and the two ends of the support seat 3 are hingedly connected to the hinge strip frame 41 through a pin shaft; the hinge strip frame 41 is fixedly installed on the inner side wall of the mounting box 1.

[0058] The above-mentioned leaflet scattering mechanism also includes a control structure 4 for controlling the turning angle of the support seat 3, and the sliding speed of the leaflet placed on the support seat 3 is controlled by controlling the turning angle of the support seat 3.
[0059] Specifically, the control structure 4 includes a rectangular adjusting through hole 42 respectively arranged on the support seat 3; the position of the rectangular adjusting through hole 42 is located near the outer side edge of the support seat 3.
[0060] At the same time, the control structure 4 also includes an electric telescopic rod 43 (the electric telescopic rod 43 is a conventional multi-stage telescopic electric telescopic rod disclosed in the prior art, which is fixedly installed at the top position in the top cover 12), the telescopic end position of the electric telescopic rod 43 is fixedly connected with a pull rod 44 penetrating from the position of the rectangular adjusting through hole 42 of each support seat 3, and the bottom of the pull rod 44 is fixedly connected with a plurality of support seats 45 arranged at intervals and supported at the bottom position of the support seat 3.
[0061] Under normal circumstances, all support seats 3 remain horizontal, at this time, the leaflets placed on the support seat 3 remain horizontal stability.
