[0002] Walnuts, also known as Juglans regia, have high nutritional value. All parts of their roots, stems, leaves, and fruits have their uses. It can be said that "the whole body is a treasure", and it is one of the most widely distributed tree species among Chinese economic tree species. China mainly processes walnut kernels, and the main products include walnut kernel foods, walnut oil, walnut health products, etc., fully reflecting the huge edible value of walnut planting and processing.

[0003] When conducting walnut detection and processing, X-rays can be used to detect and screen the interior of walnuts. However, after the screening of the existing walnut detection and sorting devices, only the binary classification of good and bad walnuts can be achieved, and multi-classification cannot be carried out. Therefore, in order to achieve the goal of multi-classifying walnuts according to certain standards based on their internal structures, a four-class sorting device is specifically proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a four-class sorting device for walnut detection, so as to solve the problem that only binary classification of good and bad can be achieved during the detection process, and multi-classification according to classification standards cannot be achieved as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sorting device includes a frame, a chain conveyor belt, a belt classification structure, and an air blowing structure. The chain conveyor belt includes idler rollers and an anti-double-walnut structure. A servo motor is installed on one side of the chain conveyor belt, and four rows of air blowing structures are installed at the bottom of the chain conveyor belt at a certain angle in the vertical direction. Four rows of belt classification structures are arranged above the chain conveyor belt. The belt classification structure includes a belt motor, a belt, a protective cover, and a shock-absorbing plate. A classification crossing is installed on one side of the belt classification structure.

[0006] Further, the servo motor is installed on the frame and is connected to the sprocket shaft through a coupling to drive the sprocket to rotate, thereby making the entire chain conveyor belt move.

[0007] Further, the anti-double-walnut structure is at a certain height above the idler rollers and is connected to the bottom of the shock-absorbing plate of the belt classification structure by welding.

[0008] Further, the air blowing structure is located at the bottom of the chain conveyor belt, corresponding to the belt classification structure, and is installed on the frame. It consists of an air nozzle channel and air nozzles, and is at a certain angle in the vertical direction.

[0009] Furthermore, the belt classification structure is located above the chain conveyor belt and is installed on a frame, and includes a belt motor, a belt and a pulley, a shock absorbing plate, and a protective cover.

[0010] Furthermore, the small servo motor is connected to the pulley shaft through a coupling to drive the belt to rotate, and the belt is installed on the frame with a motor.

[0011] Furthermore, the pulley and belt are mounted on the shock-absorbing plate and are detachably connected.

[0012] Furthermore, the shock absorbing plate is mounted on the frame in a detachable connection.

[0013] Furthermore, the protective cover is mounted on the shock absorbing plate and is detachably connected.

[0014] Furthermore, the classification crossing is located on one side of the belt classification structure, installed on the frame, and connected by welding.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The four-category sorting device for walnut detection can realize the four-category classification of walnuts according to their internal structures through the chain roller transmission structure, belt classification structure and air blowing structure, thus greatly saving manpower and material resources.

[0017] The utility model can make the walnuts be scanned in the scanning room in an orderly manner through the setting of the frame, the chain roller transmission structure and the double walnut prevention structure through a specific feeder. After the walnuts enter the scanning room, they are irradiated with X-rays to obtain the appearance shape and internal structure information of the walnuts, and then transmit the information to the server, which makes a comparison and judgment, so as to quickly distinguish which category the walnuts belong to, and in the process of the movement, open the air nozzle in time to blow the walnuts into the correct classification port.

[0018] The utility model can realize four classifications of walnuts through the arrangement of the motor, belt, protective cover, shock-absorbing plate, air nozzle channel, air nozzle, and classification passage in the belt classification structure. When the walnut moves to the specified position, the air nozzle opens and blows the walnut onto the belt. In order to prevent the walnut from splashing and its kinetic energy from being too large, a shock-absorbing plate and a protective cover are specially arranged. The walnut blown into the belt moves together with the belt. When it moves to the end of the belt, the walnut enters the corresponding classification passage, thereby realizing four classifications.

[0019] Through the above process, the sorting device can achieve the purpose of classifying walnuts into four categories according to their internal structures, greatly saving manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figures 1-5 , an example provided by the present utility model:

[0028] A four - category sorting device for walnut detection. The X - ray machine detection body (9), sprocket (17), chain conveyor belt (4), motor (2), belt pulley (16), and belt (14) used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all prior arts well - known to those skilled in the art, so they will not be elaborated here. The air nozzle (8) and the air nozzle channel (7) are located below the roller chain, specifically below the belt sorting mechanism, and are welded to the frame (1). There is a shock - absorbing plate (12) between the two belts. A protective cover (13) is installed on the shock - absorbing plate. The bottom of the shock - absorbing plate is connected to the anti - double - walnut mechanism (6) by welding.

[0029] Working principle: When the staff uses this device, first, connect the device to an external power supply to provide power support for the device. Secondly, this sorting device also needs to be matched with a feeding mechanism to work together. First of all, the walnuts enter the small idler chain through the feeding device. The anti-double-walnut mechanism can ensure that each walnut entering the idler is a single walnut. As the idler moves, the walnuts are transported to the detection box. The data collected by the detection box is sent to the server. The server classifies the walnuts into four categories according to the standards, and at the same time collects the position and speed information of the walnuts. As the idler continues to move, the walnuts are transported to the sorting section. At the appropriate position, the server controls the opening and closing of the air nozzles to blow the walnuts upward and let them fall onto the sorting belt. The shock-absorbing device absorbs energy and reduces vibration. The belt moves, transports the walnuts through the sorting channels, and sends them to the correct positions. The above is all the working principles of this utility model.
