[0002] The core of soil testing and formula fertilization technology is to regulate and solve the contradiction between crop fertilizer demand and soil fertilizer supply, and at the same time to supplement the nutrients needed by crops in a targeted manner. After the compound fertilizer particles are dried in the dryer, their temperature is usually high, and some particles may disintegrate due to the granulation process. High temperature or disintegration can easily lead to poor absorption of compound fertilizer particles by crops. Compound fertilizer particles pile up together to form lumps, which also make it difficult for crops to absorb compound fertilizer particles. At present, a spray nitro compound fertilizer anti-caking device is used to treat compound fertilizers.

[0003] Existing anti-caking devices usually include the following structure: A comparative document with publication number "CN210463942U" discloses an anti-caking device for spraying nitro-compound fertilizer, including an outer barrel body, and an inner leakage barrel that is lifted and installed inside the outer barrel body; a lifting seat is provided on both sides of the top of the outer barrel body; a sliding screw assembly is installed on the inner side of the lifting seat; a connecting rod is fixed between the sliders of the sliding screw assemblies of the two lifting seats.

[0004] Although the above-mentioned comparative document solves the problem of product agglomeration caused by the high packaging temperature of the finished product of sprayed nitro-compound fertilizer, it has the following disadvantages: since the compound fertilizer rotates together with the inner leakage barrel, it cannot be stirred greatly inside the inner leakage barrel, which easily leads to a better cooling effect on the compound fertilizer near the inner wall of the inner leakage barrel, and a poor air cooling effect on the compound fertilizer in the middle of the inner leakage barrel. The compound fertilizer in the middle is still prone to agglomeration, and the effect of anti-caking treatment of the compound fertilizer is poor. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, the embodiment of the utility model proposes an anti-caking device for spraying nitro-compound fertilizer, including an outer barrel body 1, a barrel door, a cold air fan 8 and an inner leaking barrel 2 rotatably arranged on the outer barrel body 1, the inner leaking barrel 2 is a hollow structure, and a plurality of through holes connected to the interior thereof are opened on the surface, a first servo motor 17 is fixedly connected to the outer barrel body 1, a support frame 19 is fixedly connected to the inner leaking barrel 2, a driving end of the first servo motor 17 is connected to the support frame 19 through a rotating shaft 3 to drive the first servo motor 17 to rotate, one end of the rotating shaft 3 is fixedly connected to the driving end of the first servo motor 17, and the other end of the rotating shaft 3 is fixedly connected to the support frame 19, the cold air fan 8 is connected to an air cooling head through a plurality of air cooling pipes 9, and the cold air fan 8, the air cooling pipes 9 and the air cooling head are all installed on the outer barrel body. 1 (wherein the air cooler 8 has been disclosed in the comparative document with publication number CN210463942U, and its working principle is not repeated here), a rotating rod 5 is rotatably connected in the inner leakage barrel 2, a second servo motor 18 is installed on the inner leakage barrel 2, a driving end of the second servo motor 18 is fixedly connected to the rotating rod 5, a reciprocating screw rod 15 is fixedly connected to the lower end of the rotating rod 5, a fixed block 10 is threadedly connected to the reciprocating screw rod 15, a plurality of vertical rods are fixedly connected to the upper surface of the fixed block 10, the fixed block 10 is slidably connected to the inner wall of the inner leakage barrel 2, two stirring assemblies are arranged in the inner leakage barrel 2, each stirring assembly includes a sliding block 13 slidably arranged on the lower inner wall of the inner leakage barrel 2, a moving block 14 is fixedly connected to the upper end of the sliding block 13, and the moving block 14 is connected to the fixed block 10 through a hinge rod 11.

[0021] The cross-section of each articulated rod 11 is set in the shape of a rich character. The two articulated rods 11 are symmetrically arranged. During the process of the articulated rod 11 in the shape of a rich character moving together with the fixed block 10, its inclination angle will change, and the sliding block 13 moves horizontally at the same time. During the movement of the articulated rod 11, the compound fertilizer can also be stirred. The cross-section of each moving block 14 is set in the shape of an isosceles triangle. The moving block 14 is articulated with the corresponding articulated rod 11. During the movement of each moving block 14, due to the cross-section of the moving block 14 being set in the shape of an isosceles triangle, the contact area between the tip of the moving block 14 and the compound fertilizer caking is small, and the caking can be broken up.

[0022] A feed pipe 4 and a discharge pipe are fixedly connected to the inner leakage bucket 2. Pipe caps are threadedly connected to both the feed pipe 4 and the discharge pipe. The sprayed nitro compound fertilizer is put into the inner leakage bucket 2 through the feed pipe 4. After the input is completed, the pipe cap is threadedly connected to the feed pipe 4. When the air-cooling treatment of the compound fertilizer is completed, the pipe cap of the discharge pipe is opened, and the compound fertilizer in the inner leakage bucket 2 can be discharged. A plurality of rotating blades 16 are fixedly connected to the rotating rod 5. The plurality of rotating blades 16 are arranged in a ring shape. During the rotation of the rotating blades 16, the compound fertilizer in the inner leakage bucket 2 can be stirred.

[0023] Two inclined filter plates 7 are installed in the outer barrel body 1. Two discharge ports are opened on one side of the outer barrel body 1. Two cover plates 6 are clamped on one side of the outer barrel body 1. The two cover plates 6 respectively block the two discharge ports of the outer barrel body 1. A rotating block 12 is rotatably connected to the outer barrel body 1. The rotation of the rotating block 12 can knock on the filter plate 7. The filter pore sizes on the two filter plates 7 are different, and the compound fertilizer can be recycled by particle size. The cover plate 6 and the outer barrel body 1 are separated, and the discharge ports on the outer barrel body 1 are exposed on the outside. The compound fertilizer slides along the inclined filter plate 7 to the discharge port, so that the compound fertilizer on the filter plate 7 can be discharged through the discharge port.

[0024] In the present utility model, during use, the spraying nitro compound fertilizer is put into the inner leakage bucket 2 through the feed pipe 4. After the input is completed, the pipe cover is threadedly connected to the feed pipe 4. Then, the switches of the first servo motor, the second servo motor, and the air cooler 8 are turned on. Since both ends of the rotating shaft 3 are fixedly connected to the inner leakage bucket 2 and the driving end of the first servo motor respectively, under the driving action of the first servo motor, the inner leakage bucket 2 and the outer barrel body 1 rotate relative to each other. One end of the rotating rod 5 is fixedly connected to the driving end of the second servo motor, and the reciprocating screw rod 15, the rotating rod 5, and each rotating piece 16 rotate simultaneously. During the rotation of the rotating piece 16, the compound fertilizer in the inner leakage bucket 2 can be stirred. Since one end of the hinged rod 11 is hinged to the moving block 14 and the other end is hinged to the fixed block 10, and there is partial thread on the reciprocating screw rod 15, when the fixed block 10 is threadedly connected to the reciprocating screw rod 15, it will have a vertical relative sliding with the inner leakage bucket 2. During the movement of the fixed block 10 and the vertical rod, the compound fertilizer can be stirred.

[0025] During the movement of the cross-shaped hinged rod 11 together with the fixed block 10, its inclination angle will change, and the sliding block 13 moves horizontally at the same time. During the movement of the hinged rod 11, the compound fertilizer can also be stirred. During the movement of each moving block 14, since the cross-section of the moving block 14 is in an isosceles triangle shape, the contact area between the tip of the moving block 14 and the compound fertilizer caking is small, and the caking can be broken up. The air cooler 8 can perform a relatively comprehensive air-cooling treatment on the compound fertilizer. During the rotation of the compound fertilizer together with the inner leakage bucket 2, it can also have a large agitation inside the inner leakage bucket 2, so that the cooling effect on the compound fertilizer near the inner wall of the inner leakage bucket 2 is better, and the air-cooling effect on the compound fertilizer in the middle of the inner leakage bucket 2 is also better, avoiding the phenomenon of caking of the compound fertilizer in the middle, and having a better effect on preventing caking of the compound fertilizer.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
