[0027] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0030] like Figures 1 to 10As shown, the present invention's device for removing impurities from fruit and vegetables comprises a conveyor mechanism 1, a bracket 2, and an impurity removal assembly 3. The conveyor mechanism 1 is used to transport fruits and vegetables. The bracket 2 is fixed to the conveyor mechanism 1. The impurity removal assembly 3 is mounted on the bracket 2 and communicates with high-pressure gas. The impurity removal assembly 3 comprises a rotating shaft 32 and at least one nozzle 33. One end of the rotating shaft 32 is connected to the bracket 2, and the other end of the rotating shaft 32 is connected to the nozzle 33. During impurity removal, the nozzle 33 rotates about the axis a of the rotating shaft 32 to form a circular high-pressure gas spray area.
[0031] In other words, the impurity removal component 3 automatically removes impurities from the surfaces of fruits and vegetables during transport. The impurity removal component 3 is connected to a high-pressure gas via an air pipe. The high-pressure gas passes through the internal channel of the rotating shaft 32 and reaches the nozzle 33, where it is sprayed. The nozzle 33 is able to rotate about the axis a, thus forming a circular high-pressure gas spray area during rotation. Furthermore, the ejected high-pressure gas has a certain vibration. When fruits and vegetables pass through the high-pressure gas spray area, the high-pressure gas can spray and wash the surface of the fruits and vegetables, blowing away dirt and leaves on the fruit and vegetable surfaces. Furthermore, there is a certain amount of friction between the conveyor belt or conveyor roller of the conveyor mechanism 1 and the fruits and vegetables, causing them to roll during transport. Thus, substantially all surfaces of the fruits and vegetables can be blown away. Actual tests have shown that the present utility model can remove 90% of impurities from the surfaces of fruits and vegetables.
[0032] The fruits and vegetables mentioned in the present invention can be passion fruit, oranges, potatoes, etc.
[0033] The conveying mechanism 1 can be a feeding conveying mechanism or a sorting conveying mechanism. When the conveying mechanism 1 is a feeding conveying mechanism, a plurality of impurity removal components 3 are provided on one bracket 2. The number of brackets 2 can also be multiple, and each bracket 2 is provided with multiple impurity removal components 3. When the conveying mechanism 1 is a sorting conveying mechanism (when sorting, fruits and vegetables pass through the bracket 2 one by one), a impurity removal component 3 is provided on the bracket 2. The number of brackets 2 can be multiple, and each bracket 2 is provided with a impurity removal component 3. It should be noted that when the impurity removal component 3 is installed on the feeding conveying mechanism, the upper end of the rotating shaft 32 is connected to the bracket 2. When the impurity removal component 3 is installed on the sorting conveying mechanism, the upper end of the rotating shaft 32 is connected to the bracket 2 through the connecting block 31.
[0034] Specifically, the nozzle 33 includes: a connecting shaft 331, a mounting block 332 and a nozzle 333. The connecting shaft 331 is connected to the rotating shaft 32, the mounting block 332 is sleeved on the connecting shaft 331, and the nozzle 333 is arranged on the mounting block 332 for spraying high-pressure gas. A gas circulation channel is provided inside the connecting shaft 331 and the mounting block 332, and the gas circulation channel is connected to the channel inside the rotating shaft 32 so that the high-pressure gas can reach the nozzle 333. The high-pressure gas used for removing impurities can be a high-pressure gas of 0.4MPa or more. The specific gas pressure used can be adjusted according to the type of fruits and vegetables that currently need to be removed impurities. For example, the nozzle 33 is arranged on the side of the rotating shaft 32, so that a larger spraying area can be formed when the nozzle 33 rotates. The nozzle 333 sprays in a conical divergent state.
[0035] It should be noted that the rotation of the nozzle 33 can be achieved in two ways:
[0036] First, the nozzle 33's spray center direction s is nonparallel to the axis a of the rotating shaft 32. That is, the nozzle 33's spray center direction s is not perpendicular to the horizontal plane. This creates a reverse thrust when high-pressure gas is ejected from the nozzle 333, driving the nozzle 33 to rotate. In this case, the upper end of the rotating shaft 32 is rotationally connected to the connecting block 31 or the bracket 2 (for example, the rotating shaft 32 can be connected to the connecting block 31 or the bracket 2 via a micro bearing). The nozzle 33 and the rotating shaft 32 rotate together.
[0037] Second, a rotary drive member (not shown) is provided to drive the rotation of the rotating shaft 32 and the nozzle 33. The output shaft of the rotary drive member is in driving connection with the rotating shaft 32. When the rotary drive member is activated, it can drive the rotating shaft 32 and the nozzle 33 to rotate. The rotary drive member can be, for example, a motor or an electric motor with a rotational output function. When the rotary drive member is provided, the spray center direction s of the nozzle 33 can be parallel or non-parallel to the axis a of the rotating shaft 32.
[0038] When the spray center direction s of the nozzle 33 is not parallel to the axis a of the rotating shaft 32, the spray center direction s forms an angle with the horizontal plane (0°<angle<90°), and the specific angle can be adjusted according to actual needs.
[0039] It should be noted that the number of nozzles 33 can be one or more, preferably multiple (2, 3, 4, etc.). The multiple nozzles 33 are evenly distributed along the circumference of the rotating shaft 32. When there are multiple nozzles 33, the number of nozzles 333 is also multiple, and the spray center directions of the multiple nozzles 333 can be the same (for example, all spray vertically downward) or different.
[0040] For example Figure 7As shown, taking three nozzles 333 as an example, the connecting line of the three nozzles 333 forms a circle A, and the orthographic projections of the injection center directions s of the three nozzles 333 on the horizontal plane are all tangent to the circle A.
[0041] For example Figure 8 As shown, taking three nozzles 333 as an example, the line connecting the three nozzles 333 forms a circle A. The orthographic projection of the spray center direction s of nozzle number one 333 on the horizontal plane faces outside circle A, the orthographic projection of the spray center direction s of nozzle number two 333 on the horizontal plane is tangent to circle A, and the orthographic projection of the spray center direction s of nozzle number three 333 on the horizontal plane faces inside circle A. The spray center directions s of the three nozzles 333 are different, which can further form a larger spray area.
[0042] In summary, in the fruit and vegetable surface impurity removal device of the present invention, the nozzle 33 can rotate about the axis a to form a circular high-pressure gas spray area, and the ejected high-pressure gas has a certain vibration. When the fruits and vegetables pass through the high-pressure gas spray area, the high-pressure gas can spray and wash the surface of the fruits and vegetables, blowing away the dirt and leaves on the surface of the fruits and vegetables. In addition, there is a certain friction between the conveyor belt or conveyor roller of the conveying mechanism 1 and the fruits and vegetables, and the fruits and vegetables will roll during transportation. In this way, basically all surfaces of the fruits and vegetables can be blown. The present invention can remove 90% of the impurities on the surface of fruits and vegetables, which is conducive to improving the impurity removal effect and efficiency.
[0043] Based on the above-described preferred embodiments of the present invention, and in accordance with the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
