[0002] Compound fertilizer is a chemical fertilizer made by chemical or mixed methods that contains any two or three of the crop nutrient elements nitrogen, phosphorus and potassium. High-efficiency coating equipment is required in the production of compound fertilizer. High-efficiency coating equipment mainly includes coating rollers, in which the coating agent is sprayed on the compound fertilizer, and the formed particles are coated during the rolling process.

[0003] The publication number is CN215855841U, and the utility model discloses a high-efficiency coating equipment for compound fertilizer production, including a bottom plate, a first protective component and a coating roller. The top of the bottom plate is fixed with a support component and a driving device. The first protective component includes a bracket bolted to the bottom plate, a first buffer fixed to the inner wall of the bracket side, and a second buffer arranged on the inner wall of the bracket top. The first buffer includes a spring fixed to the inner wall of the bracket, a buffer plate fixed to the spring, and a buffer pad bonded to the buffer plate. In the utility model, the brackets of the first protective component and the second protective component can imprison the coating roller to prevent the coating roller from rolling down and hitting the staff, and the spring of the first buffer makes the buffer plate have a buffering effect, which prevents the coating roller from hitting the bracket to a certain extent. Since the first buffer and the second buffer have the same structure, the second buffer also prevents the coating roller from hitting the bracket to a certain extent, which greatly improves safety and has excellent practicality.

[0004] Although the above-mentioned equipment improves the safety of the staff by setting up protective components, when adding materials into the coating drum, when the material is at one end of the coating drum, it is easy to cause the coating drum to be overloaded.

The inner cavities of the two groups of annular grooves 207 are rollingly connected with a limiting component for preventing the coating drum 200 from detaching. The limiting component is installed on the top of the base plate 400 to limit the coating drum 200, so as to prevent the material from being at one end of the coating drum 200, causing the coating drum 200 to be overloaded, which is easy to cause imbalance on both sides, and then may cause the coating drum 200 to fall off, thereby improving the stability of the device.

[0030] The driving assembly includes a fixing seat 206 fixedly mounted on the top of the base plate 400, a driving motor 204 is fixedly mounted on the top of the fixing seat 206, a gear 205 is fixedly mounted on the output shaft of the driving motor 204, an annular rack 203 is fixedly mounted on the outer wall of the coating roller 200, the gear 205 and the annular rack 203 are meshed for transmission, when the driving motor 204 is damaged and needs to be replaced, the gear 205 is directly disengaged from the meshing of the annular rack 203, thereby facilitating the replacement of the driving motor 204.

[0031] The limiting component includes a U-shaped block 306 fixedly installed on the top of the base plate 400, both ends of the arc surface of the U-shaped block 306 are rotatably connected to the second roller 304, slots 302 are opened on both sides of the U-shaped block 306, and the surface of the U-shaped block 306 is connected to a U-shaped card 300, and the two ends of the U-shaped card 300 are respectively embedded in the inside of the two slots 302, and the end of the U-shaped card 300 is fixedly connected to the U-shaped block 306 by a first bolt 303. When the U-shaped card 300 needs to be replaced, the U-shaped card 300 is directly separated from the U-shaped block 306 by removing the first bolt 303, so that it is convenient for the staff to remove the U-shaped card 300.

[0032] The U-shaped card 300 is rotatably connected to a first roller 301, and the first roller 301 is rollingly connected to the inside of the annular groove 207. The U-shaped card 300 is rotatably connected to a second roller 304, and the second roller 304 is rollingly connected to the inner cavity of the annular groove 207, thereby preventing the surface of the U-shaped card 300 from contacting the coating roller 200 and causing excessive friction.

[0033] When in use, the cover plate 201 is flipped along the hinge 202 to add materials and additives to the inner cavity of the coating drum 200. When the addition is completed, the cover plate 201 is flipped to close the coating drum 200, and the drive motor 204 is started. The gear 205 fixedly installed on the output shaft of the drive motor 204 engages the annular rack 203, thereby driving the coating drum 200 to rotate, and the material in the inner cavity of the coating drum 200 is coated, and the coating drum 200 is prevented from being overloaded by the limiting component.

[0034] Example 2: See attached Figure 1-5 As shown, different from Example 1, one side of the U-shaped block 306 is slidably connected to a U-shaped plate 100, and both ends of the U-shaped plate 100 are fixedly installed with fixing components for fixing the coating roller 200, and the top of the bottom plate 400 is slidably connected to a jack 101 for lifting the U-shaped plate 100, and the telescopic end of the jack 101 is controlled to extend and retract, and the coating roller 200 is lifted through the U-shaped plate 100, so that the staff can replace the second roller 304 conveniently.

By setting the fixing assembly, the coating drum 200 is fixed to prevent the coating drum 200 from being displaced during the jacking process, which may cause danger, thereby improving the maintenance safety of the device by the staff.

[0037] A guide rod 105 is fixedly installed on one side of the clamping block 103, and one end of the guide rod 105 is movably inserted into the fixing block 102 to prevent the clamping block 103 from rotating due to tightening the hand screw 104, causing the angle of the clamping block 103 to deviate, thereby affecting the fixing effect of the coating roller 200.

[0038] When the second roller 304 rotatably installed on the surface of the U-shaped block 306 is worn out due to long-term use, the two sets of jacks 101 are taken out and placed under the U-shaped plate 100 respectively, and the telescopic ends of the jacks 101 are made to abut against the U-shaped plate 100, then the first bolts 303 fixing the U-shaped card 300 are removed and the U-shaped card 300 is removed, and the jack 101 is controlled to lift upward. When the arc surface of the U-shaped plate 100 contacts the outer surface of the coating drum 200, the hand-tightening bolts 104 are turned, and then the clamping block 103 is moved to the side of the coating drum 200 and abuts against the surface of the coating drum 200, and the remaining hand-tightening bolts 104 are tightened in turn, so as to fix the coating drum 200, and at the same time, the jack 101 is controlled to lift the coating drum 200. When it is lifted to a suitable height, the second roller 304 is disassembled and replaced.
