First embodiment
Referring to fig. 1, the present embodiment provides a particle disperser 100, which includes a material hopper 110, a first speed regulating device communicated with the material hopper 110, a second speed regulating device communicated with the first speed regulating device, and a third speed regulating device communicated with the second speed regulating device. Particle disperser 100 is used to disperse particles such as rice, rapeseed, soy, and fertilizer.
Referring to fig. 2 and 3, the first speed adjusting device includes a first housing 121, a first rotating shaft 122 disposed in the first housing 121, a first distributing wheel 123a engaged with the first rotating shaft 122, a first adjusting wheel 123b engaged with the first distributing wheel, and a first driving device 128 driving the first rotating shaft 122. The first housing 121 is provided with a first inlet 121a and a first outlet 121b, and the material in the material hopper 110 enters the first housing 121 through the first inlet 121a, and flows out of the first housing 121 through the first outlet 121 b.
In this embodiment, the first distribution wheel has first protrusions 124 extending in a radial direction of the first rotating shaft 122, and a first distribution cavity 125 is formed between adjacent first protrusions 124. The first distribution wheel 123a is fixedly connected to the first rotating shaft 122, and the first distribution wheel 123a is immovable in the axial direction of the first rotating shaft 122.
The first regulating wheel 123b has second protrusions 126 extending in a radial direction of the first regulating wheel 123b, and second cavities 127 are formed between adjacent second protrusions 126. The first protrusion 124 cooperates with the second cavity 127 and the second protrusion 126 cooperates with the first dispensing chamber 125.
The first regulating wheel 123b is movable within the first housing 121 in the axial direction of the first rotating shaft 122 to change the size of a material separating space 129 between the first regulating wheel 123b and the first housing 121, the material separating space 129 being a space formed between the bottom wall of the first housing 121 and the bottom wall of the first regulating wheel 123b, the material separating space 129 being a space indicated by an X indicated by an arrow 129 in the drawing, the X being a distance between the bottom wall of the first housing 121 and the bottom wall of the first regulating wheel 123 b. The material distributing space 129 becomes larger, the volume of the first material distributing cavity 125 in the first shell 121 becomes smaller, and less material flows out from the first outlet 121 b; the material distributing space 129 becomes smaller, the volume of the first material distributing chamber 125 in the first housing 121 becomes larger, and more material flows out from the first outlet 121 b.
The material flows out of the first outlet 121b mainly through the first distribution chamber 125, and a small portion of the material flows out of the first outlet 121b through the distribution space 129.
The first adjustment wheel 123b moves in two ways:
first, manual adjustment is employed. A first fastening member is arranged between the first adjusting wheel 123b and the first housing 121, the first adjusting wheel 123b is mounted on the first rotating shaft 122, and a first fastening member 122a for adjusting the axial position of the first adjusting wheel 123b along the first rotating shaft 122 is mounted on the first rotating shaft 122. When the position of the first fastening member 122a is changed, the volume between the first regulating wheel 123b and the first housing 121 is changed.
Second, electric regulation is used. A rack is mounted on the first adjusting wheel 123b, and a motor for driving the rack along the axial direction of the first rotating shaft 122 is mounted on the first rotating shaft 122.
The adjustment mode of the first adjustment device 120 includes two types:
first, the volume between the first regulating wheel 123b and the first housing 121 is regulated. When the volume is smaller, the volume of the first distribution chamber 125 in the first housing 121 is larger, more material enters the first distribution chamber 125 in the first housing 121 from the hopper 110, and less material flows out of the second housing 131.
Second, the rotational speed of the first driving device 128 that drives the first rotating shaft 122 is changed. When the first driving device 128 rotates at a faster speed, the first distribution chamber 125 has less material and less material is distributed from the first housing 121. When the first driving device 128 rotates at a slower speed, the first distribution chamber 125 contains more material and more material is distributed from the first housing 121.
Referring to fig. 5 to 7, the second adjusting device 130 includes a second housing 131 and a second opening and closing sheet 133, the second housing 131 has a second inlet 131a and a second outlet, the second inlet 131a is communicated with the first outlet 121b, and the second opening and closing sheet 133 is used for changing the opening degree of the first outlet 121 b.
The opening and closing degree of the second opening and closing sheet 133 can be adjusted in two ways:
first, in this embodiment, the second adjusting device 130 further includes a second pivot 132, a second opening and closing plate 133, a connecting rod 134 and a fixing rod 135, the second pivot 132 and the second opening and closing plate 133 are jointly hinged to a pivot 136, and the second pivot 132 and the second opening and closing plate 133 are connected through the connecting rod 134.

The second pivots 132 are fixed to different fixing bars 135, respectively, to adjust the positions of the second pivots 132. In the present embodiment, the second adjusting means 130 includes five fixing levers 135, so that the position of the second pivot 132 has five levels. The second pivot 132 changes the opening degree of the second opening and closing piece 133 through the connecting rod 134, thereby adjusting the opening and closing degree of the first outlet.
Second, the opening degree of the first outlet 121b is adjusted by a driving means (e.g., a motor) which drives the second pivot 132 up and down through a link 134 mechanism.
The first outlet 121b is communicated with the second inlet 131a, and when the opening degree between the second opening and closing sheet 133 and the first outlet 121b is large, more materials flow into the second shell 131 of the second adjusting device 130 from the first adjusting device 120; when the opening and closing degree between the second opening and closing piece 133 and the first outlet 121b is small, less material flows from the first regulating device 120 into the second housing 131 of the second regulating device 130.
Referring to fig. 7 and 8, the third adjusting device 140 includes a third housing 141, a third opening plate (not shown), a fourth opening plate 144, and a third material distribution wheel 153.

The third opening and closing piece is disposed in the third inlet 143a, and the third opening and closing piece is used for adjusting the opening and closing degree of the third inlet 143 a. If the opening and closing degree of the third inlet 143a is larger, more materials flow into the third inlet 143 a; the material flowing into the third inlet 143a is less when the opening and closing degree of the third inlet 143a is smaller.
The third distribution wheel 153 includes a turntable 153a and a partition 153b connected to the turntable 153a, and the turntable 153a is driven by a driving means, which is a motor in this embodiment. The partitions 153b extend in the radial direction of the rotating disk 153a, the partitions 153b are spaced apart from each other, the material flows into the space between the partitions 153b, the rotating disk 153a and the partitions 153b rotate, and the material is dispersed from the third outlet 143 b.
Referring to fig. 9, when the fourth engaging portion 144 is at the first position 151 shown by the solid line, the spreading angle of the material flowing out of the third casing 141 is relatively large, and when the fourth engaging portion 144 is at the second position 152 shown by the dotted line, the spreading angle of the material flowing out of the third casing 141 is relatively small. When a larger dispersion area is needed, a larger dispersion angle is selected; when a smaller dispersion area is desired, a smaller dispersion angle is selected.
Referring to fig. 10, the present embodiment provides an unmanned aerial vehicle 200, which includes a body 210 and the particle disperser 100, wherein the particle disperser 100 is directly or indirectly connected to the body 210.
