The acoustic suspension signal acquisition system is installed at the tail of the cleaning screen, and the piezoelectric ceramic sensor and wireless transmission chip contained in the suspension ball are used to collect and output the signal to the single-chip microcomputer. The single-chip microcomputer uses a chaotic algorithm to accurately identify the grain impact signal and obtain the grain cleaning loss amount and cleaning loss rate. The method realizes the detection of the grain impact signal of the grain combine harvester by using a chaotic algorithm; the present invention can accurately extract the grain impact signal from the noise signal, and can reduce the cost and improve the system reliability while improving the detection accuracy.

[0039] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.12, a second round rod 5 is connected to one side of the reverse thrust rod 3 through a separation component, a first pulley 6 is fixedly connected to the outer side of the second round rod 5, a screening component for screening grains is arranged at the bottom of the second round rod 5, and a collecting component for collecting grains is arranged at the bottom of the screening component, the number of the second round rods 5 is set to two, a first belt 7 is arranged on the outer side of the first pulley 6, a first rolling roller 4 is fixedly connected to the outer side of one of the second round rods 5, and a grain preliminary filtering plate 21 is rotatably connected to the outer side of the second round rod 5. By setting the grain preliminary filtering plate 21, the grains can be preliminarily filtered and screened, and at the same time, the first rolling roller 4 is set to separate the grains and grain straws, and the screening component includes a reducer 9, the output end of the reducer 9 is fixedly connected to the outer side of the second round rod 5, and the input end of the reducer 9 is fixedly connected to a reciprocating screw rod 10, and the outer side of the reciprocating screw rod 10 is connected to a slider 11 through a nut pair, and the bottom of the slider 11 is fixedly connected to a connecting rod 12, and one side of the connecting rod 12 is fixedly connected to a rack 13, and the top of the rack 13 is meshed and connected A third gear 14 is connected, a third round rod 15 is fixedly connected inside the third gear 14, and a grain filter plate 16 is fixedly connected to the outside of the third round rod 15. By arranging the rack 13 and the third gear 14, the left and right movement of the rack 13 can drive the third gear 14 to rotate back and forth, and the back and forth rotation of the third gear 14 drives the grain filter plate 16 to rotate back and forth. At this time, the grains can be further screened to prevent the grains from being mixed with straw fragments on the grains.

A first inclined plate 20 is fixedly connected to one side of the grain primary filter plate 21. By setting the slide groove, the slider 11 can be limited so that the slider 11 can move linearly.

[0040] Specifically, after the grains are harvested, the grains and straws can be separated by the grain combine harvester body 1. After the grains and straws are separated, the grains can be discharged through the discharge pipe 38, and the straws will be discharged from the rear end of the grain combine harvester body 1. When the straws are discharged, there are still a lot of grains remaining on the straws that have not been cleaned up. Therefore, it is necessary to collect the grains remaining on the straws to detect a loss of the grain combine harvester body 1 during the separation of grains and straws. When the straws are discharged from the rear end of the grain combine harvester body 1, since one side of one of the second round rods 5 is fixedly connected to a drive motor, the drive motor is started to drive the second round rod 5 to rotate, and the rotation of the second round rod 5 drives the second rolling roller 8 to rotate, and the rotation of the second round rod 5 drives the first pulley 6 to rotate. Through the cooperation of the first pulley 6 and the first belt 7, the other second round rod 5 can be driven to rotate, and the rotation of the other second round rod 5 drives the first rolling roller 4 to rotate. At this time, the grain straws can be repeatedly ground, and the grains remaining on the straws can be separately harvested. The separated grains fall into the collecting frame 18, that is, the top of the grain filtering plate 16, along the mesh holes on the bottom of the grain primary filtering plate 21.

The left and right movement of the connecting rod 12 drives the rack 13 to move left and right, and drives the third gear 14 to rotate back and forth. The back and forth rotation of the third gear 14 drives the third round rod 15 to rotate back and forth. The three round rods 15 rotate back and forth to drive the grain filter plate 16 to rotate back and forth. At this time, the grains dropped on the top of the grain filter plate 16 can be screened.

At this time, the grains can be screened again, and the straw debris dropped with the grains can be blown to one side of the partition to avoid blowing away the straw debris containing the grains. A filter net is set at the bottom between the partition and the collection frame 18. At this time, the grains can be filtered again and the lost grains can be recovered separately, so as to calculate the loss of grains later.

[0041] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.12A grain combine harvester cleaning loss detection and collection device comprises a grain combine harvester body 1 and a discharge pipe 38, wherein the discharge pipe 38 is installed on one side of the grain combine harvester body 1 for discharging grains, a first round rod 2 is arranged on one side of the grain combine harvester body 1, a reverse thrust rod 3 is fixedly connected to the outer side of the first round rod 2, a separation component comprises a first rolling roller 4, a partition is fixedly connected inside a collecting frame 18, a filter screen is arranged between the collecting frame 18 and the bottom of the partition, a visual sensor 19 is fixedly connected inside the grain combine harvester body 1, an adjustment component is arranged on one side of the grain combine harvester body 1, and fan blades 17 are arranged to clean the straw fragments contained in the grains, and the purpose of setting the partition is that when cleaning the straw fragments, the grains contained in the straw fragments will be blown away by the fan blades 17, so in order to avoid waste, the grains need to be collected and filtered again.

[0042] Specifically, a visual sensor 19 is provided inside the grain combine harvester body 1. Through the detection of the visual sensor 19, the visual sensor 19 here is the direct source of information for the entire machine vision system. It is mainly composed of one or two graphic sensors, and sometimes it is equipped with a light projector and other auxiliary equipment. The main function of the visual sensor 19 is to obtain enough of the most original image to be processed by the machine vision system. The visual sensor can make a judgment on where the machine component is located in the field of view, regardless of whether the component rotates within a 360-degree range. Here, once it is detected that there are still grains in the straw, the stepper motor is started at this time. Since the stepper motor is fixedly connected to the first round rod 2, the stepper motor drives the first round rod 2 to rotate, and the rotation of the first round rod 2 drives the reverse push rod 3 to rotate. At this time, the straw containing the grain can be pushed backwards. At this time, the straw containing the grain can be pushed between the first rolling roller 4 and the second rolling roller 8. At this time, it can be passed The first rolling roller 4 removes grains from the straw again, and the removed grains fall into the collecting frame 18 for collection according to the above working principle. If the visual sensor 19 does not detect the straw containing grains, the straw will fall from the top of the reverse thrust rod 3 after being rolled again by the first rolling roller 4, and will be discharged to the ground through the first inclined plate 20 after passing through the reverse thrust rod 3. This structure is beneficial for throwing the unclean straw from the grains removed back into the space between the first rolling roller 4 and the second rolling roller 8. At this time, the grains can be removed again, making the grain removal cleaner and avoiding waste, while also avoiding the inability to accurately calculate the grain loss rate.
