The metal foreign object detection structures 2 are distributed along a direction perpendicular to the conveying direction on the chassis 12 and are arranged parallel to the chassis 12 for detecting whether there are metal foreign objects 5 in the raw sugarcane. The control structure 3 is electrically connected to the cane feeding structure 1 and the metal foreign object detection structures 2.

Among them, the metal foreign object detection structures 2 detect the metal foreign objects 5 carried by the raw sugarcane, the control structure 3 controls the alarm structure 4 to give an alarm, and controls the conveying component 11 to stop running.

[0032] In an alternative embodiment, as Figure 2 and Figure 3As shown, the base frame 12 is provided with an insulating plate 121, and the insulating plate 121 is provided corresponding to the metal foreign body detection structure 2. In this embodiment, the base frame 12 is made of metal. In order to prevent the metal base frame 12 from affecting the detection accuracy of the metal foreign body detection structure 2, a limiting groove 127 corresponding to the insulating plate 121 is provided on the base frame 12, and the insulating plate 121 is clamped in the limiting groove 127, so that the raw sugar cane is detected by the metal foreign body detection structure 2 at the insulating plate 121.

[0033] In an optional embodiment, if Figure 1 As shown, the metal foreign body detection structure 2 includes a detection probe 21 and a bracket 22. The bracket 22 is used to install the detection probe 21. The detection probe 21 is electrically connected to the control structure 3 and is closely arranged on the surface of the insulating plate 121 away from the conveying component 11 to detect metal foreign bodies 5 carried by the raw sugar cane.

[0034] In an optional embodiment, if Figure 5 As shown, the base frame 12 includes a sugarcane feeding platform 122 and a mounting frame 123. The surface of the sugarcane feeding platform 122 facing the conveying component 11 is protruded with a plurality of guide grooves 124. Each of the guide grooves 124 is arranged parallel to the conveying direction and is used for guiding the conveying component 11. One end of the mounting frame 123 is connected to the surface of the sugarcane feeding platform 122 away from the conveying component 11, and the other end is connected to the ground support. The metal foreign body detection structure 2 and the guide grooves 124 are staggered. Specifically, the sugarcane feeding platform 122 is provided with a limiting groove 127 corresponding to the insulating plate 121, and the insulating plate 121 is clamped in the limiting groove 127 of the sugarcane feeding platform 122. The mounting frame 123 and the sugarcane feeding platform 122 can be connected by welding or threaded connection. Furthermore, the mounting frame 123 stably supports the sugarcane feeding platform 122 and can also adjust the horizontal position of the sugarcane feeding platform 122. In this embodiment, a flat-bottomed groove 125 is formed between adjacent guide grooves 124, and the conveying component 11 is a rake-tooth conveyor belt, and the rake teeth of the rake-tooth conveyor belt are movably connected in the guide groove 124. The conveyor belt is used to carry raw sugarcane, and the rake-tooth conveyor belt drives the raw sugarcane to move. When the raw sugarcane moves into the range of the insulating plate 121, it can be detected by the metal foreign body detection structure 2, and it can be determined whether the raw sugarcane is entrained with metal objects such as steel bars, machetes, chains, etc.

[0035] Furthermore, in the present embodiment, the width of the limiting groove 127 is 80 mm to 100 mm, and the width of the insulating plate 121 corresponds to the limiting groove 127 . The insulating plate 121 is made of wear-resistant bakelite and has good wear resistance and insulation performance.

[0036] In an optional embodiment, if Figure 5As shown, edge guards 126 are respectively arranged on both sides of the cane feeding table 122. The two edge guards 126 are symmetrically arranged and are used to adjust the movement of raw cane along the conveying direction. Specifically, an angle is formed between the edge guard 126 and the cane feeding table 122 to facilitate blocking the raw cane from leaving the cane feeding table 122, so that all raw canes can be detected by the metal foreign object detection structure 2, improving the detection accuracy and avoiding missed detection. The edge guard 126 is made of metal and has high strength and is not easily damaged by the impact of raw cane. At the same time, in this embodiment, the edge guard 126 and the cane feeding table 122 are connected by welding, having good connection strength.

[0037] In an alternative embodiment, as Figure 1 and Figure 4 shown, the alarm structure 4 includes a slot indicator 41 and an audible and visual alarm 42. The slot indicator 41 and the audible and visual alarm 42 are both electrically connected to the control structure 3. The slot indicator 41 is used to indicate the position where the metal foreign object 5 is detected, and the audible and visual alarm 42 is used to emit an alarm sound. Specifically, a slot indicator 41 is correspondingly arranged for each flat bottom groove 125, which can intuitively and accurately provide the slot position where the metal foreign object 5 is found for the staff, improving the work efficiency of the staff. After the metal foreign object 5 is taken out and the metal foreign object detection structure 2 does not detect the residue of the metal foreign object 5, the slot indicator 41 is turned off, while the audible and visual alarm 42 can inform the staff through the alarm sound that the metal foreign object detection structure 2 has detected the metal foreign object 5 and they need to go to deal with it quickly.

[0038] In an alternative embodiment, as Figure 1 shown, the control structure 3 includes a first intermediate relay 31 and a second intermediate relay 32. The output end of each metal foreign object detection structure 2 is electrically connected to a first intermediate relay 31. One output end of the first intermediate relay 31 is connected to the slot indicator 41, and the other output end is connected to the second intermediate relay 32. One output end of the second intermediate relay 32 is electrically connected to the audible and visual alarm 42. The first intermediate relay 31 and the second intermediate relay 32 are used to control the slot indicator 41 and the audible and visual alarm 42 to respond according to the detection result of the metal foreign object detection structure 2.

[0039] In an alternative embodiment, as Figure 1As shown, it further includes a self-stop structure 6, which is electrically connected to the control structure 3 and is used to control the stop of the conveying component 11. Specifically, the self-stop structure 6 is an AC contactor coil provided on the conveying component 11. The self-stop structure 6 is electrically connected to another output end of the second intermediate relay 32. After the metal foreign object detection structure 2 detects a metal foreign object 5 from the raw sugarcane, the second intermediate relay 32 controls the self-stop structure 6 to further control the stop of the conveying component, avoiding the metal object flowing to the next process and damaging the equipment, facilitating the staff to take out the metal object from the raw sugarcane, and at the same time adopting an automatic control method, improving the work efficiency of the staff.

[0040] In an alternative embodiment, as Figure 1 shown, it further includes a reset structure 7, which is electrically connected to the control structure 3 and is used to control the conveying component 11 to resume operation. Specifically, the normally closed contact of the reset button is connected in series on the coil circuit of the first intermediate relay 31. After taking out the metal object from the raw sugarcane, the conveying component 11 is resumed by pressing the reset button, which is simple to operate and improves work efficiency.

[0041] Working principle: Detection probes 21 are arranged on the surface of the insulating plate 121 facing away from the conveying assembly 11. All the detection probes 21 are arranged along the length direction of the insulating plate 121, and each detection probe 21 is spaced 60 mm to 80 mm apart. The cane feeding table 122 is provided with 6 to 8 flat-bottomed grooves 125. On average, each flat-bottomed groove 125 is correspondingly provided with seven or eight detection probes 21. Each detection probe 21 has a normally open output terminal. The normally open output terminals of all the detection probes 21 corresponding to each flat-bottomed groove 125 are connected in parallel. One first intermediate relay 31 is correspondingly arranged for each flat-bottomed groove 125. The normally open output terminals of the detection probes 21 after parallel connection are connected to the corresponding first intermediate relay 31. A set of normally open contacts of each first intermediate relay 31 is correspondingly connected to a slot position indicator 41, that is, one slot position indicator 41 is correspondingly arranged for each flat-bottomed groove 125, which is used to indicate the flat-bottomed groove 125 where the metal foreign object 5 is detected, facilitating the staff to quickly take out the metal foreign object 5. Then, the other set of normally open contacts of all the first intermediate relays 31 are connected in parallel and then connected to the second intermediate relay 32. A set of normally open contacts of the second intermediate relay 32 is electrically connected to the sound and light alarm device, and the other set of normally closed contacts is connected in series to the coil circuit of the self-stop structure 6 of the conveying assembly 11 to achieve interlocking. The detection range of the detection probe 21 is within 20 mm from the cane feeding table. When a detection probe 21 detects an iron metal object within this detection range, the normally open contact of the detection probe 21 closes, driving the corresponding first intermediate relay 31 to actuate and close. The corresponding slot position indicator 41 lights up to indicate the flat-bottomed groove 125 where the metal object is located. At the same time, it also drives the second intermediate relay 32 to actuate and close. After its normally open contact closes, it drives the sound and light alarm device to emit a sound and light alarm. A set of normally closed contacts of the second intermediate relay 32 simultaneously interlocks and controls the self-stop structure 6, that is, interlocks and controls the AC contactor coil of the conveying assembly 11, so that the conveying assembly 11 stops urgently, preventing the metal object from shifting, facilitating the operator to take out the metal object. After taking out the metal object, press the reset button once, and the metal object detection and alarm device of the cane feeding table 122 can return to the initial state, and the conveying assembly 11 resumes normal operation.

[0042] To sum up, by arranging the detection probe 21 that acts on the iron metal object on the conveying assembly 11, when an iron metal object passes and the distance between the iron object and the detection probe 21 meets the detection range of the detection probe 21, the detection probe 21 will output a signal, driving the first intermediate relay 31 and the second intermediate relay 32 to actuate and close. The relevant contacts of the second intermediate relay 32 then drive the sound and light alarm device and the indicator light, realizing electrical interlocking, and achieving functions such as sound and light alarm, position indication, and shutdown for processing. After the processing is completed, pressing the reset button can restore normal operation. The detection probe 21 has high detection accuracy and accurate positioning, facilitating the staff to eliminate potential hazards and effectively preventing the equipment in the next process from being damaged by the metal object.
