Description

Technical Field

[0001] This application relates to the technical field of compound fertilizer coating, and particularly relates to a coating device for compound fertilizer processing. Background Art

[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements among nitrogen, phosphorus, and potassium. Compound fertilizer has the advantages of high nutrient content, few secondary components, and good physical properties, and plays a very important role in balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yields of crops.

[0003] However, in actual applications, during the storage process of most existing compound fertilizers after processing, over time, the nutrients contained in the compound fertilizers will gradually be released. The longer the storage time, the more nutrients will be lost. As a result, during subsequent use, it is impossible to balance the nutrient requirements of crops, leading to an increase in the number of top dressings required, thus increasing the fertilization cost. At the same time, it will also have a negative impact on the soil and environment, which is not conducive to popularization and use.

[0004] Therefore, the technical personnel in this field have provided a coating device for compound fertilizer processing to solve the problems raised in the above background art. Utility Model Content

[0018] Next, the technical solutions of the present invention will be described clearly and completely in conjunction with the attached Figures 1-3 Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] An embodiment of the present application discloses a coating device for compound fertilizer processing. Refer to Figures 1-3 , which includes a pallet 1. A motor 2 is fixedly connected to the bottom side of the pallet 1. The output shaft of the motor 2 is fixedly connected to a cross bar 3. A gear 4 is fixedly sleeved on the outer side of the cross bar 3. A toothed ring 5 is meshed and connected to the outer side of the gear 4. The inner wall of the toothed ring 5 is fixedly connected to a rotating barrel 6. Two U-shaped frames 7 are fixedly connected to the top side of the pallet 1. The same cross pipe 8 is fixedly connected to the outer sides of the two U-shaped frames 7. A plurality of spray holes are opened on the bottom side of the cross pipe 8. The cross pipe 8 is located inside the rotating barrel 6. By setting the rotating barrel 6, the output shaft of the motor 2 drives the cross bar 3 to rotate, the cross bar 3 drives the gear 4 to rotate, the gear 4 drives the toothed ring 5 to rotate, and the toothed ring 5 drives the rotating barrel 6 to rotate. When the rotating barrel 6 rotates, the worker pours the compound fertilizer into the inside of the rotating barrel 6 from the left side of the rotating barrel 6, and at the same time injects the coating oil into the cross pipe 8. The injected film oil uniformly drips into the rotating barrel 6 from the plurality of spray holes. As the rotating barrel 6 rotates, the surface of the compound fertilizer particles will be uniformly coated with the coating oil. Using this method can effectively slow down the loss of nutrients in the compound fertilizer particles during storage, meet the nutrient requirements of subsequent crops, and avoid the increase in the number of topdressings, thereby reducing the fertilization cost and protecting the environment and soil.

[0020] In the present application, a plurality of heating rods 9 are fixedly installed on the outer side of the cross pipe 8. The plurality of heating rods 9 are all located inside the rotating barrel 6. By setting the heating rods 9, the plurality of heating rods 9 cooperate with each other to heat the internal environment of the rotating barrel 6, avoiding the solidification of the coating oil affected by the low-temperature environment, which affects the coating of the fertilizer particles.

[0021] In the present application, eight support plates 10 are fixedly connected to the top side of the pallet 1. The eight support plates 10 are divided into groups of two, and a support wheel 11 is rotatably installed on the opposite sides of each group of support plates 10. By setting the support wheels 11, when the rotating barrel 6 rotates, the four support wheels 11 cooperate with each other to support the rotating barrel 6 from the bottom side, thereby improving the stability of the rotating barrel 6 during rotation.

[0022] In the present application, the inner diameter and outer diameter at both ends of the rotating barrel 6 are smaller than the inner diameter and outer diameter at the middle position. By setting the inner diameter and outer diameter at both ends of the rotating barrel 6 to be smaller than the inner diameter and outer diameter at the middle position, when the support wheels 11 support the rotating rotating barrel 6, the displacement of the rotating barrel 6 during rotation can be avoided.

[0023] In the present application, a reinforcing block 12 is fixedly connected to the bottom side of the pallet 1. A through hole is opened at the center of the reinforcing block 12. The cross bar 3 is rotatably connected to the inner wall of the through hole. By setting the reinforcing block 12, the reinforcing block 12 can limit the cross bar 3, thereby improving the stability of the cross bar 3 during rotation and avoiding deviation.

[0024] All the standard parts used in the present utility model can be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the attached drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0025] The implementation principle of an envelope coating device for compound fertilizer processing in an embodiment of the present application is as follows: During use, the output shaft of the motor 2 drives the cross bar 3 to rotate. The cross bar 3 drives the gear 4 to rotate. The gear 4 drives the toothed ring 5 to rotate. The toothed ring 5 drives the rotating barrel 6 to rotate. When the rotating barrel 6 rotates, the worker pours the compound fertilizer into the interior of the rotating barrel 6 from the left side of the rotating barrel 6, and at the same time injects the coating oil into the horizontal pipe 8. The injected film oil uniformly drips into the rotating barrel 6 from a plurality of spray holes. As the rotating barrel 6 rotates, the surface of the compound fertilizer particles will be uniformly coated with the coating oil. By using this method, the loss of nutrients in the compound fertilizer particles during storage can be effectively reduced, meeting the nutrient requirements of subsequent crops while avoiding an increase in the number of topdressings, thereby reducing the fertilization cost and protecting the environment and soil. The multiple heating rods 9 cooperate with each other to heat the internal environment of the rotating barrel 6, preventing the coating oil from solidifying due to the influence of a low-temperature environment, which may affect the coating of the fertilizer particles. When the rotating barrel 6 rotates, the four support wheels 11 cooperate with each other to support the rotating barrel 6 from the bottom side, thereby improving the stability of the rotating barrel 6 during rotation. The inner diameter and outer diameter at both ends of the rotating barrel 6 are smaller than the inner diameter and outer diameter at the central position, so that when the support wheels 11 support the rotating barrel 6 during rotation, the rotating barrel 6 can be prevented from shifting during rotation. The reinforcing block 12 can be used to limit the cross bar 3, thereby improving the stability of the cross bar 3 during rotation and preventing deviation.
