Description

Technical Field

[0001] This utility model relates to the field of preservative spraying technology, and in particular to a preservative spraying machine. Background Technology

[0002] After jujubes are harvested, in order to extend their shelf life, inhibit the growth of microorganisms, prevent rot and mold, and make their surface look shinier and more vibrant, jujube farmers spray a layer of preservative on their surface. The main component of the preservative is potassium sorbate. Because of its low toxicity, jujube preservatives are generally safe as long as they are used in accordance with the prescribed dosage, and therefore are widely used.

[0003] Currently, in order to save costs and ensure profits, jujube farmers use manual spraying when applying preservatives to their jujubes. In manual spraying, the prepared preservative solution is poured into a spray bottle, and then the spray is applied manually. However, this method cannot guarantee the quality of the spraying. The amount of preservative sprayed on the surface of the jujubes varies, and there may even be problems with missed spraying. In addition, the efficiency of manual spraying cannot be guaranteed, and it is not possible to maintain the same spraying efficiency for a long time.

[0004] Therefore, there is an urgent need for a preservative spraying machine that can replace manual labor in spraying preservatives, thereby improving spraying efficiency and ensuring spraying quality. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] See appendix Figure 1-5The image shows a preservative spraying machine, including a feeding unit 1, a spraying unit 2, a control console 3, and a collection box 4. The feeding unit 1 includes a first support frame 5, with a hopper 11 installed at one end of the first support frame 5. The hopper 11 is generally conical, and the bottom of the hopper 11 is provided with a discharge port 12 for material to pass through. The bottom of the hopper 11 is provided with a guide plate 13 at an incline, which is used to concentrate the material to the discharge port 12. A first conveyor belt 7 is provided at an incline on the first support frame 5. The first conveyor belt 7 is located below the discharge port 12 and is equipped with a first drive motor 9. The first conveyor belt 7 includes a body, and the two sides of the body are provided with wavy skirts 14. A baffle 15 is provided between the two skirts 14. During feeding, the first drive motor 9 drives the first conveyor belt 7 to move, and the first conveyor belt 7 uses the baffle 15 to achieve quantitative conveying of the material.

[0030] The spraying unit 2 includes a second support frame 6, on which a second conveyor belt 8 is inclinedly arranged, and a second drive motor 10 is mounted on the second conveyor belt 8. The direction of the second conveyor belt 8 is opposite to that of the first conveyor belt 7.

[0031] Furthermore, a spraying frame 16 is provided on the second support frame 6. Multiple spray nozzles 17 are installed on the side of the spraying frame 16 near the second conveyor belt 8. A water pump and a preservative solution tank are connected to the spray nozzles 17.

[0032] Furthermore, the second support frame 6 is provided with a discharge hopper 25 at the discharge end of the second conveyor belt 8, and its collection box 4 is located below the discharge hopper 25 on the second support frame 6.

[0033] During spraying, the material in the hopper 11 is transferred from the first conveyor belt 7 to the second conveyor belt 8. As the material moves on the second conveyor belt 8, the preservative is evenly sprayed onto the surface through the nozzle 17 above to achieve mechanical spraying. Then the material falls from the discharge hopper 25 into the collection box 4. In this process, mechanical spraying replaces manual labor, which not only improves the efficiency of spraying, but also ensures the quality of spraying.

[0034] Furthermore, to prevent materials from jumping off the second conveyor belt 8 due to excessive speed, a first roller brush 18 and a second roller brush 19 are respectively provided at both ends of the second support frame 6 on the second conveyor belt 8. The first roller brush 18 is used to limit the rolling speed of the material on the second conveyor belt 8, and the second roller brush 19 is used to prevent the material from jumping out of the collection box 4. The first roller brush 18 and the second roller brush 19 rotate in the same direction and opposite to the direction of material movement. When the material transitions from the first conveyor belt 7 to the second conveyor belt 8, the first roller brush 18 applies an opposite force to the material to reduce the speed of the material. At the same time, when the material is sprayed and concentrated towards the discharge hopper 25, the second roller brush 19 reduces the kinetic energy of the material to prevent the material from flying out from above the collection box 4 due to excessive speed. In order to ensure that the first roller brush 18 and the second roller brush 19 can maintain the same rotation speed, motors are provided on both the first roller brush 18 and the second roller brush 19 to achieve low-speed rotation under the control of the motors.

[0035] Furthermore, in order to reduce the waste of preservative solution, several drop holes 21 are provided on the second conveyor belt 8. The diameter of the drop holes 21 is smaller than the diameter of the material. At the same time, a conical water receiving trough 22 is provided at the inner bottom of the second support frame 6. The length of the water receiving trough 22 is equal to the length of the second conveyor belt 8. The lowest end of the water receiving trough 22 is provided with a liquid outlet. A filter plate 23 is provided on the liquid outlet. The second support frame 6 is provided with a liquid collection tank 24 below the liquid outlet. During spraying, excess preservative solution is recycled into the liquid collection tank 24 through the drop holes 21 on the second conveyor belt 8.

[0036] It should be noted that, in order to facilitate the control of the material feeding speed and spraying speed, the first drive motor 9, the second drive motor 10, and the motors set on the first roller brush 18 and the second roller brush 19 are all electrically connected to the control console 3.

[0037] It should be noted that the first roller brush 18 and the second roller brush 19 have the same structure, both including rollers. The rollers are provided with several flexible roller fingers 20. When the material is restricted, the flexible roller fingers 20 apply an opposite force to the material to achieve the purpose of reverse material feeding.

[0038] It should be noted that, in order to prevent materials from rolling off the second conveyor belt 8, skirts 14 are also provided on both sides of the second conveyor belt 8.

[0039] It should be noted that in this utility model, jujubes in the background art are uniformly described as materials.

[0040] In use, the harvested material is poured into the hopper 11, and then the first conveyor belt 7 is started through the control console 3. The material falls from the discharge port 12 onto the first conveyor belt 7 and is quantitatively conveyed under the action of the baffle 15. Then the material is transferred from the first conveyor belt 7 to the second conveyor belt 8. Then the material moves on the second conveyor belt 8 under the action of the first roller brush 18. During the movement, the preservative is evenly sprayed onto the surface of the material through the nozzle 17 above. Then the material falls into the collection box 4 through the second roller brush 19 and the discharge hopper 25.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
