Description

Technical Field

[0001] The utility model relates to the technical field of fruit harvesting, in particular to a grading face cleaning device. Background Art

[0002] At present, fruits need to go through many links from ripening to selling, such as harvesting, grading, packaging, and transportation. Fruit grading and packaging need to be carried out in specific and professional factories. Although factory-based grading and packaging are conducive to accurately determining the quality of fruits, there are many fruit transportation processes, which can easily cause problems such as more fruit damage, high transportation costs, high energy consumption, and more fruit waste. In particular, the transportation and grading of some inferior fruits increase costs and waste resources. Fruit and vegetable picking machines lack internal grading and cleaning devices. Most factory assembly line grading uses weight and fixed visual grading, and cleaning uses water washing or wind blowing. Grading and cleaning are carried out in different processes, which has low work efficiency, and the overall space occupied is large and the structure is complex, which is not suitable for use in fruit and vegetable picking machines.

[0003] Some patents of fruit and vegetable picking machines can achieve fruit and vegetable grading, such as the Chinese patent announcement number CN115039574A, the patent named "Online Grading Fruit Picking Robot", which includes a picking mechanism, a transport tube, a camera, a picking linear module, a receiving mechanism, a grading linear module, a grading fruit box, a walking frame and a drive control system. The picking mechanism is used to complete the fruit picking, the transport tube is used for the inclined arrangement of the transport tube, the camera is used to obtain the spatial position of the fruit and the size, color, maturity and other information of the fruit, the picking linear module is used to drive the picking mechanism to harvest fruits at different heights, the receiving mechanism is used to receive and temporarily store the fruits rolling down from the transport tube and control whether the fruits roll out and enter the grading fruit box, and the grading fruit box is used to store fruits of different grades. The disadvantage is that it can only achieve the grading of fruits and vegetables, but cannot achieve the cleaning of fruits and vegetables. Utility Model Content

[0004] In order to solve the problem that the grading and cleaning of the existing grading and cleaning devices are performed in different processes, resulting in low work efficiency and large space occupation, the purpose of the utility model is to provide a grading and cleaning device that can achieve the function of cleaning the surface of the fruit while grading, thereby improving work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a graded cleansing device, comprising a bracket and a fruit tray arranged below the bracket, the fruit tray is provided with fruits, the bracket comprises a first bracket and a second bracket that can rotate relative to the first bracket, the second bracket is provided with a third bracket that can rotate relative to the second bracket, the second bracket comprises a pair of symmetrically arranged mounting ears, the third bracket comprises a pair of symmetrically arranged extension edges and a connecting edge arranged between the pair of extension edges, the rotation axis of the third bracket is arranged at the connection between the pair of mounting ears and the pair of extension edges, the rotation axis of the second bracket is perpendicular to the rotation axis of the third bracket, the mounting ears, the extension edges and the connecting edges form an installation space for accommodating fruits, and the connecting edges are provided with a visual detection mechanism and a wind blowing mechanism.

[0006] In the technical solution, the grading and cleaning device adopts a parallel structure design of multiple motion devices. Through the flexible combination of the first bracket, the second bracket that can rotate relative to the first bracket, and the third bracket that can further rotate relative to the second bracket, efficient collaborative operation between the mechanisms is achieved. This design not only shortens the movement time, but also improves the overall work efficiency. At the same time, the device binds the wind blowing mechanism and the visual detection mechanism, and grades the fruit through the visual detection mechanism, so that a single movement can achieve multiple target results, simplifying the motion control process. In addition, the overall layout of the device is compact and occupies a small space. It is very suitable for use inside the picking machine, which is convenient and efficient. Most importantly, the device realizes the cleaning function of the fruit surface while grading, reduces the fruit transportation process, and further improves the overall efficiency. The mounting ears, extension edges, and connecting edges and other components surround the installation space for accommodating the fruit. This structure can not only avoid the fruit, but also facilitate the cleaning and grading operations of the fruit.

[0007] The utility model is further configured such that when the grading and cleaning device is in working state, the rotating shaft of the second bracket passes through the fruit. Through this configuration, the fruit can be scanned 360 degrees without blind spots. Through this cyclic scanning method, the device can quickly and comprehensively obtain key information such as the size, color, and appearance of the fruit, so as to perform accurate and efficient grading. This design not only improves the accuracy and efficiency of grading, but also ensures that each fruit can be fully evaluated and processed.

[0008] The utility model is further configured such that the shape formed by the mounting ears, the extension edges and the connection edges is a U-shape. The U-shaped structure has a certain degree of openness and adjustability, and the operator can conveniently put the fruit into or take out the mounting space, and can also adjust the size and shape of the U-shaped structure according to actual needs to adapt to fruits of different types and sizes.

[0009] The utility model is further configured such that: the visual inspection mechanism and the wind blowing mechanism are arranged on the same side of the third bracket. Through this configuration, the visual inspection mechanism and the wind blowing mechanism can work together to achieve efficient grading and cleaning of the fruit. Since the two are located on the same side, it can ensure that the visual inspection and cleaning operations are carried out almost simultaneously, greatly improving the work efficiency. In addition, this compact layout also helps to reduce the overall size and weight of the device, making it more suitable for integration and use on a picking machine.

[0010] The utility model is further configured as follows: a first driving member for driving the second bracket to rotate is provided on one side of the first bracket, and a second driving member for driving the third bracket to rotate is provided on one side of the second bracket. Through this configuration, the rotation of the second bracket relative to the first bracket and the rotation of the third bracket relative to the second bracket are realized. This design enables the device to flexibly adjust the angle and position relationship between the brackets to accommodate fruits of different sizes, shapes and positions. Through the precise control of the first driving member and the second driving member, the device can quickly and accurately locate the fruit for efficient grading and cleaning operations. At the same time, this design also improves the degree of automation of the device, reduces manual intervention and operating difficulty, and further improves work efficiency and accuracy.

[0011] The utility model is further configured as follows: a tray for placing fruits is provided on the fruit holder, and a plurality of through holes are provided on the tray to reduce interference with the visual detection mechanism and the wind blowing mechanism. The plurality of through holes effectively reduce the potential interference of the tray with the visual detection mechanism and the wind blowing mechanism, ensuring that the visual detection mechanism can obtain clear images of the fruits without obstacles, so as to make accurate and efficient classification judgments. At the same time, when the wind blowing mechanism cleans the surface of the fruit, the wind can smoothly pass through these through holes, avoiding the situation where the wind is reflected back by the tray.

[0012] The utility model is further configured that the tray can be turned over relative to the fruit holder so that the fruit can fall out of the tray. Through this configuration, after the fruit is graded and cleaned, the tray can be turned over so that the fruit can be easily dropped out of the tray, thereby realizing automatic unloading of the fruit.

[0013] The utility model is further configured as follows: a third driving member is provided below the tray to drive the tray to move horizontally, a fourth driving member is provided below the tray to drive the tray to move vertically, and a fifth driving member is provided below the tray to drive the tray to flip relative to the fruit tray. The tray can be flexibly adjusted in multiple degrees of freedom to accommodate fruits of different sizes, shapes and positions, and to achieve accurate positioning, grading and cleaning of the fruits. Through the coordinated action of the third driving member and the fourth driving member, the tray can be quickly moved to the designated position to accurately deliver the fruit to the working area of ​​the visual inspection mechanism and the wind blowing mechanism. The fifth driving member is responsible for driving the tray to flip after the fruit processing is completed, so that the fruit can fall out of the tray smoothly and realize automatic unloading. This multi-driving member design not only improves the automation level and work efficiency of the device, but also further ensures the accuracy and reliability of fruit processing.

[0014] The utility model is further configured such that the visual inspection mechanism, the wind blowing mechanism, the first driving member, the second driving member, the third driving member, the fourth driving member and the fifth driving member are all connected to the controller. Through this configuration, the entire device can be centrally controlled and precisely coordinated by the controller to ensure that each component can efficiently and accurately complete its respective tasks when working. The controller can adjust the cleaning intensity of the wind blowing mechanism and the motion parameters of each driving member in real time according to the fruit information obtained by the visual inspection mechanism to achieve accurate grading and cleaning of the fruit.

[0015] The advantages of the utility model are: (1) the device can clean the surface of the fruit while grading it, thus reducing the fruit transportation process and improving the overall efficiency; (2) a multi-motion device parallel structure design is adopted, and through the flexible combination of the first bracket, the relatively rotatable second bracket and the further rotatable third bracket, efficient collaborative operation among the mechanisms is achieved. This design not only shortens the movement time, but also improves the overall work efficiency; (3) the wind blowing mechanism and the visual detection mechanism are bound together, so that a single movement can achieve multiple target results, simplifying the movement control process.

[0024] In this embodiment, the grading and cleaning device adopts a multi-motion device parallel structure design. Through the flexible combination of the first bracket 1.1, the second bracket that can rotate relative to the first bracket 1.1, and the third bracket 1.3 that can further rotate relative to the second bracket 1.2, efficient collaborative operation between the mechanisms is achieved. This design not only shortens the movement time, but also improves the overall work efficiency. At the same time, the device binds the wind blowing mechanism 5 and the visual detection mechanism 4, and the fruit 3 is graded by the visual detection mechanism 4, so that a single movement can achieve multiple target results, simplifying the motion control process. In addition, the overall layout of the device is compact and occupies a small space. It is very suitable for use inside the picking machine, which is convenient and efficient. Most importantly, the device realizes the cleaning function of the surface of the fruit 3 while grading, reduces the fruit transportation process, and further improves the overall efficiency. The mounting ears 1.2.1, the extension edge 1.3.1 and the connecting edge 1.3.2 and other components surround the installation space for accommodating the fruit 3. This structure can not only avoid the fruit 3, but also facilitate the cleaning operation of the fruit 3.

[0025] Preferably, the visual detection mechanism 4 is a camera, and the wind blowing mechanism 5 is a wind knife.

[0026] Preferably, the cross section of the first bracket 1.1 is circular, and the rotation axis of the second bracket 1.2 is perpendicular to the first bracket 1.1 and passes through the center of the first bracket 1.1.

[0027] In one embodiment of the present invention, reference Figure 3 When the grading and cleaning device is in working state, the rotation axis of the second bracket 1.2 passes through the fruit 3. The fruit can be scanned 360 degrees without blind spots. Through this cyclic scanning method, the device can quickly and comprehensively obtain key information such as the size, color, and appearance of the fruit 3, so as to perform accurate and efficient grading. This design not only improves the accuracy and efficiency of grading, but also ensures that each fruit 3 can be fully evaluated and processed.

[0028] In one embodiment of the present invention, reference Figure 1 The shape formed by the mounting ears, the extension edges and the connecting edges is a U-shape. The U-shaped structure has a certain degree of openness and adjustability, and the operator can easily put the fruit into or take it out of the mounting space. At the same time, the size and shape of the U-shaped structure can be adjusted according to actual needs to adapt to different types and sizes of fruits.

[0029] In one embodiment of the present invention, reference Figures 2 to 4, the rotation axis of the second bracket 1.2 is perpendicular to the rotation axis of the third bracket 1.3. When the device is running, the second bracket 1.2 and the third bracket 1.3 can rotate on different planes. This vertical layout helps to achieve more flexible and comprehensive fruit scanning and positioning, thereby ensuring that the device can accurately obtain various information of the fruit 3, such as size, color, appearance, etc., to provide accurate data support for subsequent grading and cleaning work. At the same time, this design also helps to simplify the structure of the device and improve its stability and reliability.

[0030] In one embodiment of the present invention, reference Figure 1 , the visual inspection mechanism 4 and the wind blowing mechanism 5 are arranged on the same side of the third bracket 1.3. The visual inspection mechanism 4 and the wind blowing mechanism 5 can work together to achieve efficient grading and cleaning of the fruit 3. Since the two are located on the same side, it can ensure that the visual inspection and cleaning operations are carried out almost simultaneously, greatly improving the work efficiency. In addition, this compact layout also helps to reduce the overall size and weight of the device, making it more suitable for integration and use on a picking machine.

[0031] In one embodiment of the present invention, reference Figure 1 , a first driving member 6.1 for driving the second bracket 1.2 to rotate is provided on one side of the first bracket 1.1, and a second driving member 6.2 for driving the third bracket 1.2 to rotate is provided on one side of the second bracket 1.2. The rotation of the second bracket 1.2 relative to the first bracket 1.1 and the rotation of the third bracket 1.2 relative to the second bracket 1.2 are realized. This design enables the device to flexibly adjust the angle and position relationship between each bracket to adapt to fruits 3 of different sizes, shapes and positions. Through the precise control of the first driving member 6.1 and the second driving member 6.2, the device can quickly and accurately locate the fruit 3 for efficient grading and cleaning operations. At the same time, this design also improves the degree of automation of the device, reduces manual intervention and operation difficulty, and further improves work efficiency and accuracy.

[0032] In one embodiment of the present invention, reference Figure 1 The fruit tray 2 is provided with a tray 2.1 for placing the fruit 3, and the tray 2.1 is provided with a plurality of through holes to reduce interference with the visual detection mechanism 4 and the wind blowing mechanism 5. The plurality of through holes effectively reduce the potential interference of the tray 2.1 with the visual detection mechanism 4 and the wind blowing mechanism 5, ensuring that the visual detection mechanism 4 can obtain a clear image of the fruit 3 without obstacles, so as to make accurate and efficient classification judgments. At the same time, when the wind blowing mechanism 5 cleans the surface of the fruit 3, the wind can smoothly pass through these through holes, avoiding the situation where the wind is reflected back by the tray 2.1.

[0033] It can be understood that the tray 2.1 having a plurality of through holes forms a hollow structure.

[0034] It is understandable that the tray 2.1 may be provided with an electronic scale to detect the weight of the fruit 3.

[0035] In one embodiment of the present invention, reference Figure 1 The tray 2.1 can be turned over relative to the fruit holder 2 to allow the fruits 3 to fall out of the tray 2.1. After the fruits 3 are graded and cleaned, the tray 2.1 can be turned over to conveniently allow the fruits 3 to fall out of the tray 2.1, thereby achieving automatic unloading of the fruits 3.

[0036] In one embodiment of the present invention, reference Figure 1 , a third driving member 6.3 is provided below the tray 2.1 to drive the tray 2.1 to move horizontally, a fourth driving member 6.4 is provided below the tray 2.1 to drive the tray 2.1 to move vertically, and a fifth driving member 6.5 is provided below the tray 2.1 to drive the tray 2.1 to flip relative to the fruit tray 2. The tray 2.1 can be flexibly adjusted in multiple degrees of freedom to adapt to fruits 3 of different sizes, shapes and positions, and to achieve accurate positioning, grading and cleaning of the fruits 3. Through the synergistic effect of the third driving member 6.3 and the fourth driving member 6.4, the tray 2.1 can be quickly moved to the designated position, and the fruits 3 can be accurately sent to the working area of ​​the visual inspection mechanism 4 and the wind blowing mechanism 5. The fifth driving member 6.5 is responsible for driving the tray 2.1 to flip after the fruit 3 is processed, so that the fruit 3 can smoothly fall out of the tray 2.1 to achieve automatic unloading. This multi-driving member design not only improves the automation and work efficiency of the device, but also further ensures the accuracy and reliability of fruit processing.

[0037] In one embodiment of the present invention, reference Figure 1 , the visual inspection mechanism 4, the wind blowing mechanism 5, the first driving member 6.1, the second driving member 6.2, the third driving member 6.3, the fourth driving member 6.4 and the fifth driving member 6.5 are all connected to the controller. The entire device can be centrally controlled and accurately coordinated by the controller to ensure that each component can efficiently and accurately complete its respective tasks when working. The controller can adjust the cleaning intensity of the wind blowing mechanism 5 and the motion parameters of each driving member in real time according to the fruit 3 information obtained by the visual inspection mechanism 4, so as to achieve accurate grading and cleaning of the fruit 3.

[0038] In one embodiment of the utility model, the grading and cleaning device includes a shell, an inferior fruit storage area and a qualified fruit storage area. The first bracket 1.1 is fixed to the shell. After the fruit 3 passes through the grading and cleaning device, it is transferred to the inferior fruit storage area or the qualified fruit storage area.

[0039] In this embodiment, the fruit and vegetable picking machine integrates the previously described grading and cleaning device, and is further equipped with a shell, an inferior fruit storage area, and a qualified fruit storage area. The first bracket 1.1 is fixed to the shell to ensure the stability and safety of the entire device. After the fruit 3 is processed by the grading and cleaning device, it will be automatically transferred to the corresponding storage area, that is, the inferior fruit storage area or the qualified fruit storage area according to the grading result. This design enables the picking machine to realize the integrated operation of automatic picking, grading, cleaning and classified storage of fruits and vegetables, greatly improving the picking efficiency and processing quality. At the same time, by setting up the inferior fruit storage area and the qualified fruit storage area, the fruits can also be further classified and managed, which is convenient for subsequent processing, packaging and sales.

[0040] Working process:

[0041] Step 1: Preparation before work, such as Figure 1 As shown, the first bracket 1.1 and the second bracket 1.2 are in the initial position, the third bracket 1.3 is in the horizontal position, the first driving member 6.1 and the second driving member 6.2 are in the initial position, the visual detection mechanism 4 is in a ready-to-work state, the wind blowing mechanism 5 is in a closed state, the fruit tray 2 is in a horizontal state, the fruit 3 is placed in the fruit tray 2, the tray 2.1 is in a horizontal state, the fourth driving member 6.4 is in a retracted state, and the third driving member 6.3 is in a retracted state.

[0042] Step 2: Wait for the working state, such as Figure 2 As shown, the third driving member 6.3 is extended, and the fourth driving member 6.4 is extended upward. At this time, the position of the fruit 3 is located at the center of the circulating scanning device, waiting for scanning, grading and cleaning.

[0043] Step 3: During the work process, Figure 3 As shown, the second bracket 1.2 is in motion and the third bracket 1.3 is in motion. Through the combined movement of the second bracket 1.2 and the third bracket 1.3, the fruit 3 can be scanned in an all-round cycle. During this process, the visual detection mechanism 4 continuously matches and calculates the diameter size, appearance, maturity and other information of the fruit 3 at this time, and the surface of the fruit 3 is cleaned by the compressed gas of the wind blowing mechanism 5. Since the tray 2.1 adopts a hollow structure, the interference to the visual detection mechanism 4 and the wind blowing mechanism 5 is reduced to a minimum.

[0044] Step 4: Unloading process, such as Figure 4 As shown, the second bracket 1.2 returns to the initial position, the third bracket 1.3 returns to the initial position, the fourth driving member 6.4 descends to the initial position, the tray 2.1 is driven by the fifth driving member 6.5 to flip, and the fruit 3 falls out of the fruit tray 2 and enters the inferior fruit storage area or the qualified fruit storage area. At this time, a complete grading and cleaning process is completed.

[0045] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
