Description

Technical Field

[0001] This utility model relates to the field of fertilizer granule coating technology, specifically a coating machine for the production of fruit and vegetable compound fertilizer. Background Technology

[0002] Compound fertilizer is a chemical fertilizer containing elements such as nitrogen, phosphorus, and potassium. It can provide comprehensive nutritional support for crops, promote crop growth and development, and thus improve yield and quality.

[0003] In the production process of compound fertilizers used for fruits and vegetables, in order to meet the requirements of changing the rate of nutrient release, the fertilizer needs to be coated. By regulating nutrient release through coating, the goal of efficient, environmentally friendly and convenient fertilization can be achieved, which not only meets the needs of crop growth, but also reduces resource waste and environmental pressure.

[0004] However, traditional coating methods typically involve pouring the coating solution into the compound fertilizer all at once, and then mixing it all together in a mixer. Because liquids have strong adsorption properties, when a large amount of coating solution comes into direct contact with the compound fertilizer particles, localized aggregation can easily lead to uneven coating effects. This results in some particles being coated with excessive solution, even clumping, while other particles are under-coated. This directly affects the processing precision and product quality of the compound fertilizer, and also adversely impacts subsequent storage, transportation, and application performance. Therefore, to address these issues, a coating machine for fruit and vegetable compound fertilizer production is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1-6 As shown, a coating machine for producing compound fertilizer for fruits and vegetables includes a base frame 1 and a roller 2, the roller 2 being rotatably connected to the surface of the support frame and driven by a motor;

[0035] The support frame is equipped with a controller to control the motor speed and the feeding speed;

[0036] A screen plate 7 is fixedly connected to the inner wall of the drum 2, and several screen plates 7 are provided;

[0037] The infusion tube 3 is fixedly connected to the base frame 1 by a bracket, and the end is connected to an external pressure pump for delivering the coating fluid. Several atomizing nozzles are provided on the surface of the infusion tube 3.

[0038] The roller 2 has a feed inlet and a discharge outlet at each end;

[0039] A hopper 6 is fixedly connected to the base frame 1 at the inlet, and a vertical pole 12 is fixedly connected to the base frame 1 at the outlet, with a guide plate 5 fixedly connected to the end of the vertical pole 12.

[0040] The base frame 1 is designed to tilt downwards towards the guide plate 5;

[0041] A recycling mechanism is installed on the base frame 1;

[0042] The recycling mechanism includes a recycling box 8, a card plate 13 fixedly connected to the surface of the recycling box 8, the card plate 13 is "U" shaped, and bolts are movably connected to the surface of the card plate 13. The recycling box 8 is fixedly installed on the upright 12 by bolts. The surface of the guide plate 5 is provided with filter holes, and the recycling box 8 is located below the filter holes.

[0043] During operation, the motor is first started, driving the drum 2. The drum 2 rotates clockwise with the direction of the guide plate 5 as a reference. Then, the compound fertilizer granules to be coated are poured into the hopper 6. The controller then opens the hopper 6, allowing the compound fertilizer to flow into the drum 2. Simultaneously, the infusion pipe 3 sprays out the coating liquid. Because the drum 2 is rotating, the sieve plate 7 inside the drum 2 lifts the compound fertilizer. As the compound fertilizer is lifted and falls, the atomizing nozzle sprays the coating liquid onto the compound fertilizer granules. Since the base frame 1 is tilted, the compound fertilizer granules are repeatedly lifted and scattered, thus achieving the coating purpose. Because the compound fertilizer granules absorb the coating liquid in a sprinkled state, the coating liquid is distributed more evenly, thus improving the coating effect. The roller 2, together with the sieve plate 7 and the infusion pipe 3, can replace the traditional coating method, avoiding direct contact between a large amount of coating liquid and the compound fertilizer granules, which would lead to uneven coating effect. It can also significantly reduce the occurrence of fertilizer granule clumping, improve the processing precision and product quality of compound fertilizer, and facilitate subsequent storage, transportation and application. The filter holes can filter out the coating liquid residue that is not coated on the fertilizer granules, or the residue generated by the compound fertilizer during the stirring process, thereby improving the quality of compound fertilizer production.

[0044] At least two sieve plates 7 are provided and are evenly distributed. The sieve plates 7 are inclined arc-shaped designs. During operation, the inclined arc-shaped sieve plates 7 can briefly stop the fertilizer particles and carry them as high as possible, thereby making the compound fertilizer particles more dispersed. Multiple sieve plates 7 can improve the lifting effect of compound fertilizer.

[0045] The guide plate 5 is approximately "T" shaped and has an overall arc shape. The horizontal end of the guide plate 5 is located inside the roller 2 and is used to receive compound fertilizer granules. During operation, the arc-shaped guide plate 5 can gather the compound fertilizer granules towards the center, making it easier to package them.

[0046] A comb plate 11 is fixedly connected to the surface of the infusion tube 3 via a connecting rod. A stop bar is fixedly connected to the end of the sieve plate 7. A through groove is opened at the end of the sieve plate 7. The groove 9 on the surface of the comb plate 11 corresponds to the through groove. During operation, if clumps occur, the clumps of compound fertilizer will be blocked by the stop bar. At this time, as the roller 2 continues to rotate, it will be driven to the position of the comb plate 11. Because the groove 9 of the comb plate 11 corresponds to the through groove, and the surface of the stop bar has rounded corners, when the comb plate 11 passes through the sieve plate 7, it will squeeze and break up the clumps of fertilizer particles, thereby reducing the clumping of compound fertilizer particles.

[0047] Example 2

[0048] Please see Figure 7 As shown in the comparative embodiment one, as another embodiment of this utility model, the surface of the upright 12 is rotatably connected to the rotating rod 17 via an elastic element. The rotating rod 17 is arc-shaped, and an impact head 16 is fixedly connected to the end of the rotating rod 17. Several extrusion shafts 15 are fixedly connected to the surface of the roller 2, and rubber pads are fixedly connected to the surface of the extrusion shafts 15. During operation, when the roller 2 rotates, it will drive the extrusion shafts 15 to rotate. When the extrusion shafts 15 rotate to the position of the rotating rod 17, the extrusion shafts 15 will squeeze the rotating rod 17 to rotate, and at the same time drive the impact head 16 to disengage from the guide plate 5. After the extrusion shaft 15 passes the lever, the impact head 16 impacts the guide plate 5 under the drive of the elastic element. The impact head 16 impacts the guide plate 5 and generates vibration, thereby clearing and cleaning the filter holes on the surface of the guide plate 5 and reducing blockage. The rubber pads on the surface of the impact head 16 can reduce the wear caused by the impact and effectively extend the service life of the impact head 16 and the guide plate 5.
