Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer coating, and specifically relates to a coating device. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility. It is one of the material bases of agricultural production. A coating machine is required for coating in the production of fertilizer.

[0003] Traditional coating machines generally deliver fertilizer from one end into an inclined cylinder, spray coating liquid onto its surface through a spraying device, and then perform coating operations with the help of the rotation of the cylinder. This mode easily causes a large amount of fertilizer to flow in and accumulate together, and the coating liquid cannot be evenly coated on the fertilizer, which in turn affects the use effect of the fertilizer. For this purpose, a coating device is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a film coating device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coating device, comprising an inclined cylinder, the inner end of the cylinder is equipped with spaced retaining rings, a separation chamber is formed between two adjacent retaining rings, a notch is provided at the lower end of the inner wall of the retaining ring corresponding to the cylinder for allowing the fertilizer to slide along the inclined surface of the cylinder, a rotating drum is rotatably mounted on the inner end of the retaining ring, and an annular push plate extending to the inside of the separation chamber is installed on the outer wall of the rotating drum, and a spraying assembly for spraying coating liquid into the separation chamber is installed on the outside of the cylinder.

[0006] Preferably, a feed hopper is installed at the high end of the upper surface of the cylinder, and the discharge port of the feed hopper is connected to the two separation chambers.

[0007] Preferably, a rotating shaft is installed inside the rotating drum and is connected to the inner wall of the rotating drum through a connecting rod. A convex ring is installed at one end of the rotating drum, and the convex ring is rotatably installed in a limiting sleeve installed at the end of the cylinder. A connecting sleeve is rotatably installed at the other end of the rotating drum, and the connecting sleeve is connected to the cylinder through a bracket.

[0008] Preferably, a support base is installed at the bottom of the cylinder, a motor mounting bracket is installed on the support base, and a motor for driving the rotating shaft to rotate is installed on the motor mounting bracket.

[0009] Preferably, the spray assembly includes a connecting pipe, which is installed on the outside of the cylinder, and a connecting head is installed at the end of the connecting pipe. The connecting pipe is equipped with a nozzle that extends into the separation chamber and is flush with the inner wall of the cylinder.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: a coating device can divide the cylinder into multiple equal parts by a baffle ring arranged in the cylinder. When the fertilizer in the feed hopper enters the cylinder, it separates the fertilizer to prevent excessive accumulation of fertilizer. The opening of the separation chamber can be blocked by the rotating drum. The fertilizer can be pushed to move by the push plate and roll between the two baffles. The coating liquid sprayed by the spraying component is attached to the fertilizer to mix it evenly. When the fertilizer passes through the notch, it will slide downward along the inclined surface of the cylinder, and then be rolled into other separation chambers by different push plates, so that the surface of the fertilizer passes through multiple spraying processes, thereby ensuring that the surface coating of the fertilizer is more uniform. The push plate fits the inner wall of the cylinder, which can also prevent the fertilizer from sticking to the inner wall of the cylinder and the baffle ring. The present invention first separates the fertilizer to avoid accumulation, and in the coating process, it is also carried out separately and sprayed multiple times to make the fertilizer coating more uniform.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-5The utility model provides a technical solution: a coating device, comprising an inclined cylinder 1, the inner end of the cylinder 1 is equipped with a spaced-apart baffle ring 2, a separation chamber 3 is formed between two adjacent baffle rings 2, a notch 4 is provided at the lower end of the inner wall of the baffle ring 2 corresponding to the cylinder 1 for allowing the fertilizer to slide along the inclined surface of the cylinder 1, a rotating drum 5 is rotatably mounted on the inner end of the baffle ring 2, and an annular push plate 6 extending to the inside of the separation chamber 3 is mounted on the outer wall of the rotating drum 5, and a spray component for spraying coating liquid into the separation chamber 3 is installed on the outside of the cylinder 1.

[0019] The retaining ring 2 divides the separation chamber 3 into a plurality of equal chambers.

[0020] The outer wall of the drum 5 is in contact with the inner wall of the retaining ring 2 .

[0021] The push plates 6 in two adjacent separation chambers 3 are arranged in a staggered manner.

[0022] A feed hopper 7 is installed at the high end of the upper surface of the cylinder 1 , and the discharge port of the feed hopper 7 is connected to the two separation chambers 3 .

[0023] The feed hopper 7 can be replaced by a uniform feeder.

[0024] The fertilizer to be coated is placed in the feed hopper 7, and the fertilizer enters the two separation chambers 3 from the discharge port of the feed hopper 7. The fertilizer in the separation chamber 3 slides along the surface of the rotating drum 5 and is limited by the push plate 6. Then, under the rotation of the rotating drum 5, the fertilizer is transported to the spraying assembly, and the coating liquid is sprayed on its surface. Then, as the rotating drum 5 rotates, the fertilizer rolls and coats in multiple chambers separated by the push plate 6 in the separation chamber 3. When it reaches the notch 4, part of the fertilizer will slide down from the notch 4 along the inclined surface of the cylinder 1 because there is no retaining ring 2 to block it. When other push plates 6 rotate to the notch 4, the fertilizer at the notch can be rotated into the corresponding separation chamber 3, and then the coating liquid is sprayed again through the spraying assembly until the fertilizer slides down along the inclined surface of the cylinder 1 through the notch of the last separation chamber 3, completing the coating of the fertilizer.

[0025] A rotating shaft 8 is installed inside the rotating drum 5 and is connected to the inner wall of the rotating drum 5 through a connecting rod. A convex ring 9 is installed at one end of the rotating drum 5, and the convex ring 9 is rotatably installed in a limiting sleeve 10 installed at the end of the cylinder 1. A connecting sleeve 11 is rotatably installed at the other end of the rotating drum 5, and the connecting sleeve 11 is connected to the cylinder 1 through a bracket.

[0026] A support base 12 is installed at the bottom of the cylinder 1 , a motor mounting bracket 13 is installed on the support base 12 , and a motor 14 for driving the rotating shaft 8 to rotate is installed on the motor mounting bracket 13 .

[0027] The spray assembly includes a connecting pipe 15 , which is installed on the outside of the cylinder 1 , and a connecting head 16 is installed at the end of the connecting pipe 15 . The connecting pipe 15 is installed with a nozzle 17 that extends into the separation chamber 3 and is flush with the inner wall of the cylinder 1 .

[0028] Working principle: The fertilizer is fed into the feed hopper 7, and the fertilizer enters the two separation chambers 3 through the discharge port of the feed hopper 7. The fertilizer slides along the outer wall of the rotating drum 5 and fits into the push plate 6. The motor 14 is started, and the motor 14 drives the rotating shaft 8 and its rotating drum 5 to rotate. When the push plate 6 pushes the fertilizer through the spraying assembly, the coating liquid is sprayed on the fertilizer. Under the rotation of the rotating drum 5, the fertilizer sticky with the coating liquid rolls in the chamber separated by the two push plates 6 in the separation chamber 3, so that the surface of the fertilizer is sticky with the coating liquid. When the fertilizer reaches the notch 4, due to its inclined setting of the cylinder 1, the fertilizer slides from the notch 4 along the inclined surface of the cylinder 1, and then under the rotation of the rotating drum 5, when different push plates 6 rotate to the notch 4, the fertilizer is rolled into the corresponding separation chamber 3, and this is repeated until the fertilizer in the last separation chamber 3 reaches the notch 4, and the fertilizer with uniform coating slides down.
