[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] In order to solve the technical problem that the inside of agglomerated fertilizers cannot be coated with powder, the utility model provides a powder spraying mechanism which can disperse the agglomerated fertilizers and make the powder spraying effect better.

[0028] It should be noted that the powder spraying mechanism described in the utility model is used for but not limited to fertilizer powder spraying, etc. For the convenience of explanation, in the utility model, only a powder spraying mechanism applied to fertilizer powder spraying is used as an example for explanation, and the principle of a powder spraying mechanism applied to other types of equipment is substantially the same as the principle applied to fertilizer powder spraying, which will not be repeated here.

[0029] See also Figure 1 - Figure 3 A powder spraying mechanism includes a shell 1 and a flip assembly 2. The side wall of the shell 1 is provided with a first feed port 11, and the first feed port 11 is fixedly connected to a feed pipe 12. The inner wall of the feed pipe 12 is provided with a powder spraying head 121. The flip assembly 2 includes a rotating drum 21 and a driving member 22. The rotating drum 21 is located in the shell 1. A plurality of drop holes 211 are provided on the side of the rotating drum 21. A second feed port 212 is provided at one end of the rotating drum 21. The second feed port 212 is communicated with the first feed port 11. The other end of the rotating drum 21 is transmission-connected to the driving member 22.

[0030] In this embodiment, a powder spraying head 121 is provided on the inner wall of the feed pipe 12, so that when the fertilizer is transmitted in the feed pipe 12, the fertilizer can be fully contacted with the isolation powder by continuous rolling, and then through the setting of the driving member 22 and the rotating drum 21, the fertilizer in the rotating drum 21 that cannot pass through the drop hole 211 will continuously collide with the rotation of the rotating drum 21, thereby causing the agglomerated fertilizer to be dispersed under continuous collision, and the fertilizer inside the agglomerated fertilizer can also be coated with the isolation powder, which effectively improves the powder spraying effect of the fertilizer.

[0031] First, the fertilizer enters the feed pipe 12, and the powder spraying head 121 sprays the fertilizer with powder; then, the fertilizer passes through the feed pipe 12, the first feed port 11 and the second feed port 212 in sequence and enters the drum 21; finally, the fertilizer with a volume smaller than the drop hole 211 escapes from the drum 21 by passing through the drop hole 211, and the fertilizer with a volume larger than the drop hole 211 (agglomerated fertilizer) continuously turns and collides in the drum 21 as the drum 21 rotates, until the agglomerated fertilizer is dispersed and passes through the drop hole 211 to be discharged from the drum 21.

[0032] It should be noted that the shape of the material drop hole 211 is a bar, which is conducive to improving the efficiency of the fertilizer passing through the material drop hole 211.

[0033] It should be noted that the width of the strip-shaped drop hole 211 is equal to the volume of a fertilizer, so as to prevent agglomerated fertilizer from passing through the drop hole 211 .

[0034] In one embodiment, see Figure 4 The number of the powder spraying heads 121 is at least two, and each powder spraying head 121 is fixedly connected to the inner wall of the feeding pipe 12 .

[0035] In this embodiment, a plurality of powder spraying ports are provided on the side wall of the feed pipe 12 , and the powder spraying head 121 is connected to the powder spraying ports. The powder spraying head 121 continuously sprays isolation powder into the feed pipe 12 through the powder spraying ports.

[0036] In one embodiment, see Figure 2 A first rotating hole 13 is provided on a side of the shell 1 opposite to the first feed port 11 , and the driving member 22 passes through the first rotating hole 13 and is fixedly connected to the rotating drum 21 .

[0037] In this embodiment, the fixed end of the driving member 22 is fixedly connected to the outer wall of the shell 1, and the output end of the driving member 22 passes through the first rotating hole 13 and is fixedly connected to the side of the rotating drum 21 away from the second feed port 212, and the driving member 22 drives the rotating drum 21 to rotate in the shell 1.

[0038] In one embodiment, see Figure 1 , the feed pipe 12 is a curved pipe.

[0039] In this embodiment, the curved feeding pipe 12 increases the collision probability of the fertilizer, and the fertilizer can fully contact with the isolation powder by continuously rolling in the curved feeding pipe 12.

[0040] In one embodiment, see Figure 4 A funnel 14 is fixedly connected to one end of the feed pipe 12 away from the first feed port 11 .

[0041] In this embodiment, the funnel 14 serves to facilitate the delivery of fertilizer to the feed pipe 12 .

[0042] In one embodiment, see Figure 5 A disc 15 is sleeved on one end of the feed pipe 12 away from the first feed port 11 , and a pair of hinged rods 151 are fixedly connected to the side wall of the disc 15 . The two hinged rods 151 are arranged opposite to each other and hinged to the inner wall of the feed pipe 12 .

[0043] In this embodiment, the function of the disc 15 is to control the flow rate of the feed pipe 12. The amount of fertilizer entering the feed pipe is controlled by the rotation angle of the disc 15, thereby controlling the powder spraying efficiency of the fertilizer.

[0044] In one embodiment, see Figure 4 A second rotating hole 122 is formed at one end of the feed pipe 12 away from the first feed port 11 , and a handle 152 is fixedly connected to one end of the hinge rod 151 passing through the second rotating hole 122 .

[0045] In this embodiment, the handle 152 serves to facilitate the staff to drive the disc 15 to rotate through the handle 152 .

[0046] In one embodiment, see Figure 3 A plurality of baffles 213 are fixedly connected to the interior of the rotating drum 21 .

[0047] In this embodiment, the baffle 213 serves to strengthen the collision of the fertilizer in the drum 21. The baffle 213 rotates together with the drum 21, and the agglomerated fertilizer can be continuously lifted by the baffle 213 and hit the inner wall of the drum 21, thereby effectively ensuring the dispersion of the fertilizer and avoiding agglomeration of the fertilizer.

[0048] In one embodiment, see Figure 2 , the bottom of the shell 1 is in an inclined state.

[0049] In this embodiment, the inclined bottom facilitates the fertilizer to be discharged from the bottom of the shell 1 .

[0050] In one embodiment, see Figure 2 A discharge port 16 is provided at the bottom of the shell 1 .

[0051] In this embodiment, the function of the discharge port 16 is to facilitate the discharge of fertilizer from the housing 1 .

[0052] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0053] First, the fertilizer enters the hopper 14; then, the staff turns the handle 152 according to the required powder spraying efficiency, thereby driving the disc 15 to open the feed pipe 12; then, the fertilizer enters the feed pipe 12, and the powder spraying head 121 sprays the fertilizer, and the fertilizer continuously rolls in the feed pipe 12, so that the fertilizer and the isolation powder are in more complete contact; then, the fertilizer passes through the feed pipe 12, the first feed port 11 and the second feed port 212 in sequence and enters the drum 21; secondly , the fertilizer with a volume smaller than the drop hole 211 passes through the drop hole 211 and the discharge port 16 in turn, and is discharged from the shell 1; finally, the driving member 22 is started, and the fertilizer with a volume larger than the drop hole 211 (agglomerated fertilizer) continuously turns and collides in the drum 21 as the drum 21 rotates, until the agglomerated fertilizer is dispersed and passes through the drop hole 211 and the discharge port 16 in turn, so that the fertilizer inside the agglomerated fertilizer can also be coated with the isolation powder, which effectively improves the fertilizer powder spraying effect.

[0054] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model.
