At least two cutting devices are connected to the bottom of the slide table 4, and the cutting devices are driven to align with the parent to be cut by the movement of the slide table 4; the cutting device comprises a knife shaft 11 connected to the slide table 4 and a knife shaft driving motor 6 for driving the knife shaft to move, and a plurality of moving blades 10 are arranged on the knife shaft 11 at intervals, and each moving blade 10 is correspondingly provided with a matching fixed knife 26, and the position of the fixed knife 26 is adjustable. A matching grain divider, each grain divider comprises a front grain divider 19 and a rear grain divider 16 connected to each other, and the matching grain dividers are arranged on both sides of the cutting device, and the two front grain dividers 19 are located at the front end of the knife shaft 11, and the opening and closing angles of the two front grain dividers 19 are adjustable. A plurality of movable blades 10 are arranged at intervals on the blade shaft 11, and each movable blade 10 is provided with a matching fixed blade 26, which can cut the stem of the male parent into multiple smaller segments, and the cut male parent can be directly used as agricultural fertilizer.

[0029] The cutting device is connected to the bottom of the slide 4 through the cooperation of the slide rail 3 and the slide 4 on the support frame 1. The slide 4 can drive the cutting device to move horizontally, so that the cutting device can be accurately controlled to align with the middle of the parent. In the cutting device, the moving blade 10 is disc-shaped, and multiple moving blades 10 are evenly arranged along the blade shaft 11, and each moving blade 10 is correspondingly provided with a fixed blade 26. The moving blade 10 and the fixed blade 26 are used in combination, and the position of the fixed blade 26 is adjustable. The position of the fixed blade 26 is changed according to the amount of feed, which can solve the blockage problem in the cutting and crushing process. The opening and closing angle of the divider can be reasonably adjusted according to the width of the parent to achieve accurate cutting of the parent.

[0030] According to the actual production and planting requirements, a single row or multiple rows of male parents can be cut at the same time; by increasing the number of cutting devices, at least two rows of male parents can be cut at a time. The rice oil referred to in this application refers to rice and rapeseed.

[0031] In one embodiment, the cutting device includes a knife shaft 11 connected to a slide 4 and a knife shaft driving motor 6 for driving the knife shaft to move. A plurality of movable blades 10 are arranged at intervals on the knife shaft 11. Each movable blade 10 is provided with a matching fixed knife 26, and the position of the fixed knife 26 is adjustable. The knife shaft driving motor 6 is located at the top of the knife shaft 11 and connected to the gear box 5. The knife shaft driving motor 6 is connected to the upper plate of the gear box 5 through an M7 anti-slip screw 9. The knife shaft driving motor 6 transmits power to the gear box 5. The gear box 4 reduces the speed of the knife shaft driving motor 6 and then transmits the power to the knife shaft 11. Preferably, when the knife shaft 11 is long, a knife shaft support plate 13 and a bearing 12 are installed at the upper and lower ends of the knife shaft 11. In order to make it run stably, the structural stability can be increased by the knife shaft support plate 13 and the bearing 12.

[0032] The fixed knife 26 is connected to the fixed knife slide rail 28 through the fixed knife slide 27. The position of the fixed knife 26 can be adjusted by the movement of the fixed knife slide 27.

[0033] In one embodiment, it also includes a visual recognition device and a controller 8. The controller 8 includes a host computer and a control device. The control device controls the drive of the entire machine. The visual recognition device is installed at the front end of a traveling mechanism 100 connected to a support frame. The visual recognition device includes a connecting bracket 29 and a binocular camera 30. The binocular camera 30 is fixed to the front end of the traveling mechanism 100 through the connecting bracket 29. The binocular camera 30 obtains the image data of the rice oil parent and transmits the image data of the rice oil parent to the host computer. The host computer identifies and analyzes the image data of the rice oil parent to determine the position of the parent. The host computer transmits the processed data to the control device. The control device controls the movement of the slide transmission motor 23 and the knife shaft drive motor 6 to align the parent for cutting.

[0034] In one embodiment, after the upper computer recognizes and analyzes the image data of the rice oil parent, it fits the center line of the position of the parent, and transmits the relevant data to the control device, which controls the slide transmission motor 23 to drive the slide 4 to move to the position aligned with the center line, and controls the knife shaft drive motor 6 to idle. The knife shaft drive motor 6 idles in advance to complete the accumulation of power in advance before contacting the parent crop for cutting, so as to prevent excessive cutting resistance, grass entanglement or excessive impact at the beginning of contact.

[0035] Specifically, the control box 8 is fixed to the middle position of the support frame 1 through the support plate 7, and two ears with holes are provided at the left and right ends of the control box 8. The two ears are connected and fixed to the support plate 7 by M8 screws 9. A pulley 20 and a belt 21 are provided on the slide rail 3, and a fixed platform 24 is provided on the top of the cutting device. One end of the belt 21 is fixed on the fixed platform 24, and the slide drive motor 23 drives the pulley 20 to rotate, thereby driving the belt 21 to rotate, and the belt 21 drives the fixed platform 24 to drive and control the cutting device to move horizontally to align with the parent that needs to be cut. The slide is used to control the cutting device to move parallel on the support frame, so that the parent can be aligned. Since the rice oil parent is mostly planted in a relatively neat manner, the moving distance adjustment range of the cutting device is set between 0 and 500 mm. In order to prevent exceeding the specified range, a stopper 2 and a stopper 15 are provided at both ends of the support frame 1. Both stoppers are equipped with sensing devices. When the slide 4 approaches, the slide drive motor 23 stops running.

[0036] Furthermore, preferably, the image of the rice oil parent is obtained by using a binocular camera 30, and the binocular camera 30 transmits the image data to the host computer through an aviation joint, and the host computer recognizes and analyzes the acquired image and fits the center line of the parent. The host computer transmits the processed data to the control device, and the control device transmits the signal to the slide drive motor 23 and the knife shaft drive motor 6, and the slide drive motor 23 drives the slide 4 to the fitted parent center line, and at the same time makes the knife shaft drive motor 6 idle.

[0037] In order to identify the parent of rice oil during high ground clearance driving and fit the center line of the target crop, it is convenient to place the cutting device in the middle of the crop. Before use, this device has acquired and stored a large number of photos of the parent of the crop, marked the photos taken, marked the parent in the picture, and then processed the image to form a data set, which is used for machine training and learning. When using this device, the binocular camera 30 is compared with the data in the data set for identification and analysis, and the position of the parent can be determined, and a center line can be fitted in the parent crop. The above device uses a visual recognition device to obtain the position of the parent and has an automatic row alignment function.

[0038] Furthermore, it also includes a feed amount detection device 25 fixed on the cutting device, and the feed amount detection device 25 sends the collected data to the controller, and the controller adjusts the position of the fixed knife 26 according to the feed amount; a load response device is provided in the knife shaft drive motor 6, and the speed of the knife shaft drive motor 6 is controlled according to the feed amount and the feedback data of the load response device. The real-time state of the motor is transmitted to the control device through the load response device in the knife shaft drive motor 6 and the feed amount detection device 25, and the control device automatically adjusts the position of the fixed knife 26. Specifically, when the feed amount detection device 25 detects the data fed back to the control box 8, the position of the fixed knife 26 will be changed. For example, when the feed amount is too large, in order to reduce the load of the cutting knife, the fixed knife 26 will be slowly moved backward. The position of the fixed knife 26 is changed according to the size of the feed amount to solve the blockage problem. This is because the cutting position is determined by the position of the fixed knife 26. When the fixed knife 26 is forward, the cutting position follows the forward position. Therefore, when the feed volume is relatively large, the knife 26 needs to be moved backwards to ensure that the cutting position is closer to the rear end when the feed volume is large, so as not to cause congestion in the front.

[0039] Preferably, the feed amount sensor 25 is a magnetic attraction device, which is magnetically attracted to the rear end of the knife shaft support plate 13 to facilitate the measurement of the feed amount. The measured signal is transmitted to the control box 8. If the feed amount is too large, the speed of the knife shaft drive motor 6 is increased, and the speed of the high ground clearance walking mechanism is reduced, thereby achieving a good cutting effect; conversely, if the feed amount is too small, the speed of the knife shaft drive motor 6 is reduced, and the speed of the high ground clearance walking mechanism is increased.

[0040] In one embodiment, an electric push rod 18 is provided on the crop divider for adjusting the opening and closing angle of the front crop divider 19. Specifically, the front crop divider 19 and the rear crop divider 18 are connected by a hinge 14, and a hanging ear 17 is provided at the connection between the front crop divider 19 and the rear crop divider 16, and the hanging ear 17 is connected to the front crop divider 19 through the electric push rod 18, and the opening and closing angle of the front crop divider 19 is controlled by the extension and retraction of the electric push rod 19. For example, when two rows of male parents need to be harvested, the front crop divider 19 is opened by a control device, and when one row of male parents needs to be harvested, the front crop divider 19 is folded. In addition, controlling the angle of the crop divider can also control the amount of feed, so as to achieve the effect of precise cutting.

[0041] Preferably, the walking mechanism is a 100 high ground clearance walking mechanism, and the support frame 1 is provided with a cross bar 22, which is connected to the rear end of the high ground clearance walking mechanism through a three-point suspension device 31. The three-point suspension device 31 can be lifted and lowered to drive the rice oil parent cutting device to move up and down to a suitable height for cutting the parent.

[0042] The specific working process of the above rice oil parent cutting device can be found in Figure 5Before starting work, first set the standard range value of the feeding amount, then move the cutting device up and down to the appropriate height, identify the position of the father parent through the binocular camera, and control the slide to move the cutting device to align with the center line of the father parent row. The knife shaft drive motor first idles, adjusts the front divider of the divider to fit on both sides of the father parent row, adjusts the position of the fixed knife and the speed of the knife shaft drive motor, and starts cutting the father parent row. During work, the feeding amount detection device detects the feeding amount of the father parent and compares it with the initial standard range value. When it exceeds the range value, adjusts the position of the fixed knife, the speed of the knife shaft drive motor and the opening and closing angle of the divider to complete the cutting activity.

[0043] According to the structure of the present application, the above-mentioned rice oil parent cutting device can not only achieve precise row alignment in specific work, but also adjust the speed of the knife shaft drive motor, the position of the fixed knife and the opening and closing angle of the straw divider according to the amount of feed, thereby greatly improving the cutting efficiency and saving labor costs.

[0044] Compared with the prior art, the beneficial effects of the present invention are as follows: the cutting device is connected to the bottom of the slide table through the cooperation of the slide rail 3 and the slide table 4 on the support frame 1, and the cutting device can be driven to move horizontally through the slide table 4, so that the cutting device can be accurately controlled to align with the middle of the male parent. In the cutting device, a plurality of movable blades 10 are arranged at intervals on the knife shaft 11, and each movable blade 10 is correspondingly provided with a fixed knife 26 for matching, so that the male parent stem can be cut into multiple small segments of smaller lengths, and the cut male parent can be directly used as agricultural fertilizer. An electric push rod 18 is installed on the grain divider to adjust the opening and closing angle of the grain divider. When the male parent of a single-row crop is cut off, a signal is given by the controller, and the electric push rod 18 extends forward, and the electric push rod drives the ear 17 on the front grain divider to merge inward to achieve the row spacing width of a single row; when the male parent of a double-row crop is harvested, a signal is given by the controller, and the electric push rod 18 shrinks inward, and the electric push rod 18 drives the ear 17 on the front grain divider to expand outward to achieve the row spacing width of a double row.

[0045] The present application adopts a binocular camera 30 placed at the front end of the high ground clearance walking structure, connected to the console installed on the support frame 1 through an aviation joint, the upper computer in the console analyzes and identifies the image transmitted by the binocular camera 30, determines the location of the parent, transmits the signal to the control device, controls the motor to align the cutting device with the middle of the parent for cutting, and the feeding amount detection device detects the amount of the parent cut in real time, feeds back the data to the control device, and controls the rotation speed of the knife shaft 11. Compared with the use of traditional machinery and manual labor, this design has the advantages of saving time and labor, high efficiency and low cost.
