A slot is also provided on the frame 1 for the mounting plate 23 to be raised and lowered.

[0047] Specifically, the covering structure 7 includes a fixing frame 71 mounted on the top of the frame 1, a third electric push rod 72 is installed on the top of the fixing frame 71, and the telescopic end of the third electric push rod 72 is connected to a fixing plate 73, a covering plate 74 is installed at the bottom of the fixing plate 73, and a through cavity is also opened on the frame 1 for the fixing plate 73 to be raised and lowered.

[0051] When fertilizer is added into the storage barrel 4 through the feeding hopper 5, the first motor 61 can be used to drive the rotating shaft 62 to rotate, so that the rotating shaft 62 drives the stirring blade 63 to rotate, so as to stir the fertilizer in the storage barrel 4, break up the agglomerated fertilizer, and then facilitate the discharge of the fertilizer through the discharge pipe 10, so as to avoid the agglomerated fertilizer from being blocked in the discharge pipe 10, so as to facilitate the rapid discharge of the spreading device.

[0052] Embodiment 2:

[0053] Based on Example 1, please refer to Figure 2 , Figure 6 and Figure 8 As shown, a material distribution structure 9 is provided on the spreading pipe 8, and the material distribution structure 9 includes an auger 92 rotatably installed inside the spreading pipe 8, and a second motor 91 fixed on one side of the spreading pipe 8, and the second motor 91 is used to drive the auger 92 to rotate.

[0054] When the fertilizer is discharged into the spreading pipe 8 through the discharge pipe 10 for spreading, the auger 92 can be driven to rotate forward or reverse in the spreading pipe 8 by the forward and reverse rotation of the main shaft of the second motor 91, so as to divert the fertilizer discharged into the spreading pipe 8, so that the fertilizer is evenly discharged into multiple spreading barrels 15, thereby achieving uniform fertilization of the soil by the spreading device, which can not only improve the fertilization effect, but also reduce the waste of fertilizer, and thus is conducive to the efficient fertilization of the spreading device.

[0055] Embodiment three:

[0056] Based on Example 1, please refer to Figure 5 As shown, a filter disc 11 is also installed inside the material storage barrel 4, and the filter disc 11 divides the interior of the material storage barrel 4 into a crushing cavity and a collecting cavity, and the stirring blade 63 is located in the crushing cavity.

[0057] When the first motor 61 drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the stirring blade 63 to rotate to stir the fertilizer, the fertilizer will fall on the filter plate 11, and the granular fertilizer can directly fall through the filter holes on the filter plate 11, while the agglomerated fertilizer is formed into particles after being stirred and crushed by the stirring blade 63, and then falls through the filter holes on the filter plate 11, thereby filtering and screening the fertilizer, thereby improving the stirring and crushing effect, and preventing the agglomerated fertilizer from falling directly into the discharge pipe 10 when added to the storage barrel 4, causing the discharge pipe 10 to be blocked, which is beneficial to the rapid discharge of the sowing device and convenient for fertilizing the soil.

[0058] Embodiment 4:

[0059] Based on Example 3, please refer to Figure 5 and Fig. 9 As shown, a scraper 14 is also mounted on the rotating shaft 62 . The scraper 14 is located below the rotating shaft 62 , and the bottom of the scraper 14 contacts the upper surface of the filter disc 11 .

[0060] When the first motor 61 drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the stirring blade 63 to rotate, the rotating shaft 62 can drive the scraper 14 to rotate along the upper surface of the filter disc 11 to scrape the fertilizer remaining on the upper surface of the filter disc 11, so that the fertilizer falls through the filter holes on the filter disc 11, thereby avoiding that part of the fertilizer remains on the upper surface of the filter disc 11, preventing the filter disc 11 from being blocked, and thus facilitating the filtering and screening of the fertilizer by the filter disc 11, further preventing the discharge pipe 10 from being blocked, and facilitating the rapid discharge of the spreading device.

[0061] Embodiment five:

[0063] Furthermore, two material baffle plates 13 are installed at the bottom of the rotating shaft 62 , and the bottoms of the two material baffle plates 13 are in contact with the top of the discharge tray 12 .

[0064] After the fertilizer is stirred by the stirring mechanism 6, when it falls on the discharge disc 12 through the filter holes on the filter disc 11, part of the fertilizer rolls to the discharge area on the discharge disc 12 and falls into the discharge pipe 10 through the discharge hole 16, while the other part of the fertilizer falls on other areas on the discharge disc 12. At this time, the first motor 61 drives the rotating shaft 62 to rotate, so that the rotating shaft 62 drives the stirring blades 63 to rotate, and drives the two baffle plates 13 to rotate along the top of the discharge disc 12. Then the two baffle plates 13 alternately block the two discharge areas, so that the fertilizer falling on other areas of the discharge disc 12 is pushed to the discharge area, and finally discharged into the discharge pipe 10 through the discharge hole 16, so as to realize the control of the discharge amount of the storage barrel 4, which is conducive to the uniform discharge of the fertilizer, avoids the blockage of the discharge pipe 10, and is conducive to the uniform spreading of the fertilizer.
