[0059] Based on the above structure, the material to be detected is placed on the transport component 12 of the first conveying assembly 1, and the belt member 123 drives the material to move by rotating the driving wheel 121. The material will pass through the foreign object detection component 3 during the movement. When the foreign object detection component 3 detects the presence of foreign objects in the material, the material is preliminarily detected, and the first push rod component 13 drives the driven wheel 122 to change its position, so that a gap is formed between the belt member 123 and the first conveyor belt 22, so that the material falls between the frame 11 and the conveying frame 21.

Through the cooperation of the second push rod component 52, the baffle 53 can be relatively moved along the width direction of the first conveyor belt 22. When the material is located on one side of the baffle 53, the baffle 53 is driven to move by the second push rod component 52, so that the baffle 53 can push the material, thereby removing the material with foreign matter.

[0062] The conveying frame 21 has a notch 211, one end of which extends to the outside of the conveying frame 21, so that the end face of the notch 211 is parallel to the top end face of the first conveyor belt 22, and the storage plate 51 has a slot 511 connected to the notch 211. The setting of the notch 211 enables the material to move smoothly from the position of the first conveyor belt 22 to the position of the conveying frame 21, and fall to the outside of the conveying frame 21 without being limited by the conveying frame 21. The connection between the slot 511 and the notch 211 can form a cavity for accommodating the material, thereby facilitating the passage of the material.

Through the arrangement of the tripod component 6, a gap can be formed between the frame 11 and the ground, thereby facilitating the heat dissipation operation of the components inside the frame 11, and the tripod component 6 can be quickly installed or disassembled through the threaded connection. At the same time, the rotation of the connecting rod 62 can realize the adjustment of the position height of the tripod component 6 when carrying the frame 11.

[0067] A roller member 7 is also provided at the bottom of the frame 11. There are several roller members 7 and they are located between the tripod members 6.

When the support pad 61 contacts the ground, the roller member 7 can be suspended, so that the frame 11 maintains a stable state when placed on the ground. When the support pad 61 in the tripod member 6 drives the support pad 61 away from the ground with the cooperation of the connecting rod 62, the roller member 7 contacts the ground, thereby pushing the frame 11, facilitating the subsequent adjustment of the position of the frame 11 and the conveying frame 21. The provision of several roller members 7 can disperse the pressure borne by the frame 11 when it moves, thereby facilitating the operator to push the frame 11.

[0068] In one embodiment, referring to Figure 1 and Figure 3 The pushing assembly 5 includes a guide rod 54, both ends of which are respectively connected to the two sets of storage plates 51, and a portion of the guide rod 54 passes through the baffle 53. The guide rod 54 is located above the second pushing rod component 52. Since the baffle 53 is moved by the cooperation of the second pushing rod component 52, in order to avoid the baffle 53 being offset by external collision during movement, the baffle 53 is sleeved on the guide rod 54, so that the baffle 53 can move along the length direction of the guide rod 54 when it moves, and the baffle 53 is limited by the guide rod 54, thereby avoiding the position of the baffle 53 from being offset when it moves.

[0069] In one embodiment, referring to Figure 1 and Figure 3 Storage hoppers 213 are provided on both sides of the conveying frame 21. The storage hoppers 213 are located on one side of the storage plate 51. The setting of the storage hoppers 213 can collect the materials when the materials are pushed to the outside of the conveying frame 21 by the baffle 53 controlled by the second push rod component 52. The setting of the two sets of storage hoppers 213 can realize the collection of materials when the baffle 53 pushes the materials in different directions.

The foreign body detection device for agricultural product processing and production according to claim 1 is characterized in that: A second conveyor belt is also provided in the frame, and the second conveyor belt is located below the transport component; The conveying direction of the second conveyor belt is opposite to the conveying direction of the transport component, and the length of the second conveyor belt is greater than the length of the belt member.

4. The foreign body detection device for agricultural product processing and production according to claim 1, characterized in that: The material turning assembly further comprises a latch, and the conveying frame is provided with a mounting hole, and a plurality of the mounting holes are provided and are spaced apart along the length direction of the conveying frame; One end of the support plate has an extension portion, and the extension portion has a through hole with the same diameter as the mounting hole. When the through hole is aligned with one group of the mounting holes, the latch member passes through the mounting hole and the through hole to fix the support plate on the conveying frame.

5. The foreign body detection device for agricultural product processing and production according to claim 3 is characterized in that: A feed hopper is provided at one end of the frame facing the conveyor frame. When the end surface of the belt member is away from the first conveyor belt to form a gap, the feed port of the feed hopper is connected to the gap, and the discharge port of the feed hopper is located above the second conveyor belt.

6. The foreign body detection device for agricultural product processing and production according to claim 1 is characterized in that: The bottom of the frame has a tripod component, the bottom of the frame is provided with thread grooves around, the tripod component includes a support pad and a connecting rod, the connecting rod is arranged on the support pad, and the outer periphery of the connecting rod has a raised thread; Through the cooperation of the raised thread, when the connecting rod is threadedly connected to the thread groove, the support pad abuts against the ground.

7. The foreign body detection device for agricultural product processing and production according to claim 6, characterized in that: The bottom of the frame is also provided with a roller member, and a plurality of the roller members are provided and are located between the tripod parts. With the cooperation between the threaded groove and the connecting rod, when the support pad is away from the ground, the outer periphery of the roller member fits with the ground.

8. The foreign body detection device for agricultural product processing and production according to claim 2, characterized in that: The pusher assembly includes a guide rod, and both ends of the guide rod are respectively connected to the two groups of storage plates; Part of the guide rod passes through the baffle.

9. The foreign body detection device for agricultural product processing and production according to claim 1, characterized in that: Storage hoppers are arranged on both sides of the conveying frame, and the storage hoppers are located on one side of the storage plate.

10. A method for detecting foreign matter in agricultural product processing and production, according to the device for detecting foreign matter in agricultural product processing and production according to any one of claims 1 to 9, characterized in that: The steps of this method are as follows: S1: placing the material on the belt member of the transport component and moving it, and according to the detection condition of the material passing through the foreign object detection component, the material is moved to the receiving plate of the material turning component or falls from the belt member with the cooperation of the first push rod component; S2: The material on the receiving tray rotates with the cooperation of the driving motor, so that the material turns over onto the first conveyor belt and passes through the foreign object detection component again; S3: According to the re-detection result of the foreign matter detection component, the baffle in the pushing assembly is controlled by the second push rod component to contact with the material or to be away from the material, thereby finally completing the detection and collection of the material.
