The upper end of each rotating rod is fixedly connected with a gear. Above the support plate, a fixed ring is placed, and a plurality of teeth arranged in a circumferential array are fixedly connected to the inner wall of the fixed ring. For this fertilizer grinding device, when the rotating column drives the plurality of rotating rods to rotate, through the meshing of the gears and the teeth, the rotating directions of the plurality of rotating rods and the rotating column are opposite, so that the first stirring column rotates clockwise and the second stirring column rotates counterclockwise, which can fully stir the fertilizers in the mixing tank and make the fertilizers in the mixing tank fully mixed, thus solving the problem that it is difficult for the mixing device to fully mix the fertilizers. However, after the solid fertilizers are mixed, when the fertilizer mixing device in the prior art is in use, if the discharge pipe is blocked, it will cause difficulties in discharging the fertilizers, and there is a lack of measures to dredge the discharge port; and it is not convenient to clean and maintain the inside of the device.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiments:

[0027] Such as Figures 1-6As shown in the figure, a fertilizer mixing device for grain planting includes a mixing barrel 1 with legs. A barrel cover 2 is detachably connected to the mixing barrel 1. A feed inlet 21 for adding fertilizers is provided on the barrel cover 2. In this embodiment, two feed inlets 21 are provided, which helps to add different fertilizers simultaneously. A stirring mechanism 3 is provided on the barrel cover 2. The stirring mechanism 3 is arranged on the barrel cover 2 so that it is convenient to remove the stirring mechanism 3 together with the barrel cover 2 and clean and maintain the stirring mechanism 3. The lower end of the mixing barrel 1 is connected with a discharge pipe 4 in a communicating way. A sealing cover (the sealing cover is a conventional technology and will not be elaborated here) is provided at the free end of the discharge pipe 4. The inner bottom wall of the mixing barrel 1 is an inverted cone, which helps the fertilizers to move to the discharge pipe 4. A dredging mechanism 5 is provided at the connection between the inner bottom wall of the mixing barrel 1 and the discharge pipe 4. The dredging mechanism 5 is used to dredge the blocked discharge pipe 4.

[0028] As Figures 1-6 shown, the dredging mechanism 5 includes two positioning rods 51 fixedly connected to the inner bottom wall of the mixing barrel 1. A moving frame 52 slides on the two positioning rods 51. In this embodiment, the moving frame 52 is cross-shaped. A first operating frame 53 is fixedly connected to the lower end surface of the moving frame 52. The first operating frame 53 penetrates the bottom wall of the mixing barrel 1 and slides in the mixing barrel 1. A plurality of dredging rods 54 are also fixedly connected to the middle part of the lower end surface of the moving frame 52. The dredging mechanism 5 further includes a limiting mechanism 55 arranged on the outer bottom wall of the mixing barrel 1 for limiting the downward movement of the moving frame 52. If the discharge pipe 4 is blocked by fertilizers, by pulling the moving frame 52 downward, the dredging rods 54 are inserted into the fertilizers at the discharge pipe 4, breaking the force balance state between the fertilizers blocked at the discharge pipe 4 and dredging the blocked fertilizers. The upper end surface of the moving frame 52 is arc-shaped, which helps the staff to continue to push the moving frame 52 upward. Repeatedly moving the moving frame 52 up and down helps to dredge the blocked discharge pipe 4.

[0029] As Figures 1-6 shown, limiting rings 56 are fixedly connected to the upper end and the rod body of the positioning rod 51. Through the limitation of the two limiting rings 56, the moving frame 52 can only move a fixed distance and will not come out of the positioning rod 51.

[0030] As Figures 1-6 shown, the limiting mechanism 55 includes a suspension rope 551 fixedly connected to the outer bottom wall of the mixing barrel 1. A hook 552 is fixedly connected to the free end of the suspension rope 551. The first operating frame 53 is hung on the hook 552 to limit the downward movement of the moving frame 52. When it is necessary to dredge the discharge pipe 4, the hook 552 is disengaged from the moving frame 52, and then the dredging mechanism 5 can be used normally.

[0031] As Figures 1-6As shown in the figure, the stirring mechanism 3 includes a driving motor 31 installed on the bucket lid 2 and a rotating rod 32 rotatably connected to the bucket lid 2. One end of the rotating rod 32 is fixedly connected to the output end of the driving motor 31, and the other end of the rotating rod 32 is located inside the mixing bucket 1, and a stirring rod 33 is fixedly connected to the rod body. The driving motor 31 is electrically connected to an external power supply and electrically connected to a control unit (not shown in the figure). By the output of the driving motor 31, the rotating rod 32 rotates, and the stirring rod 33 stirs the chemical fertilizer in the mixing bucket 1.

[0032] As Figures 1-6 shown in the figure, a cleaning mechanism 6 for cleaning the inner wall of the mixing bucket 1 is further provided on the bucket lid 2. The cleaning mechanism 6 includes a second operating frame 61 penetrating and sliding on the bucket lid 2. One end of the second operating frame 61 located inside the mixing bucket 1 is fixedly connected with a cleaning ring 62. The peripheral side wall of the cleaning ring 62 is attached to the inner wall of the mixing bucket 1. By pulling the second operating frame 61 up and down, the chemical fertilizer particles adhered to the inner wall of the mixing bucket 1 can be dropped by the cleaning ring 62. At the same time, the cleaning mechanism 6 can also be removed together with the bucket lid 2, and the stirring mechanism 3 can also be removed together with the bucket lid 2, which is convenient for cleaning and maintaining the inside of the device, and is also convenient for cleaning and maintaining the stirring mechanism 3 and the cleaning mechanism 6.

[0033] As Figures 1-6 shown in the figure, a plurality of cleaning rings 62 are provided. In this embodiment, two cleaning rings 62 are provided, and a connecting rod 63 is fixedly connected between adjacent two cleaning rings 62.

[0034] As Figures 1-6 shown in the figure, a first connecting plate 7 is fixedly connected to the side wall of the bucket lid 2, a second connecting plate 8 is fixedly connected to the side wall of the mixing bucket 1, and a plug rod 9 is inserted on the first connecting plate 7 and the second connecting plate 8. Through the cooperation of the first connecting plate 7, the second connecting plate 8 and the plug rod 9, relative rotation between the bucket lid 2 and the mixing bucket 1 is prevented, and the connection stability is improved.

[0035] As Figures 1-6 shown in the figure, two fixing rods 10 are fixedly connected to the lower end surface of the bucket lid 2 near the feed port 21, and a flow dividing block 11 is fixedly connected between adjacent two fixing rods 10. The flow dividing block 11 is conical. By providing the flow dividing block 11, the chemical fertilizer particles added from the feed port 21 can be dispersed and dropped into the mixing bucket 1, so that the chemical fertilizer is dispersed and the stirring and mixing efficiency is improved.

[0036] The working principle of a chemical fertilizer mixing device for grain planting in this embodiment is as follows: When in use, first add chemical fertilizers into the mixing barrel 1 from the feed inlet 21, stir the chemical fertilizers through the stirring mechanism 3, open the discharge pipe 4 to let the mixed chemical fertilizers flow out. If the discharge pipe 4 is blocked, detach the moving frame 52 from the hook 552, pull down the moving frame 52, so that the dredging rod 54 is inserted into the chemical fertilizers at the discharge pipe 4, breaking the force balance state among the chemical fertilizers blocked at the discharge pipe 4 and dredging the blocked chemical fertilizers; Pulling the second operating frame 61 up and down can make the cleaning ring 62 drop the chemical fertilizer particles adhering to the inner wall of the mixing barrel 1. At the same time, the cleaning mechanism 6 can also be detached together with the barrel cover 2, and the stirring mechanism 3 can also be detached together with the barrel cover 2, which is convenient for cleaning and maintaining the inside of the device, and is also convenient for cleaning and maintaining the stirring mechanism 3 and the cleaning mechanism 6.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
