Detailed implementation manners

[0030] In order to better understand the purpose, structure and function of the present utility model, the following will make a further detailed description of the present utility model with reference to the accompanying drawings.

[0031] As Figures 1 to 9As shown in the figure, the utility model provides a sunflower automatic disk cutting and disk inserting device, which includes a main frame 1, and a disk guiding and conveying mechanism 2, a feeding and weeding mechanism 3, a stem cutting mechanism 4, a residual stem breaking mechanism 5, and a disk inserting mechanism 6 respectively arranged on the main frame 1. Among them, the main frame 1 is used to set other mechanisms and mount the device on common working vehicles such as four-wheel agricultural vehicles and harvesters outside. The disk guiding and conveying mechanism 2 is mainly used to guide and straighten the mature sunflower disks 27 in front of the device, and mainly includes a conveying table 12 for supporting the sunflower disks 27 and a clamping and conveying track for clamping the sunflower stems 29 directly below the sunflower disks 27. The conveying tables 12 are arranged in pairs on the left and right sides above the main frame 1, and there is a stem passing channel 7 left in the middle for the sunflower stems 29 to pass through. The clamping surface of the clamping and conveying track is vertically arranged, and the clamping channel 8 is located directly below the stem passing channel 7, and is used to convey the straightened sunflower stems 29 vertically backward;

[0032] Corresponding to the conveying table 12, the feeding and weeding mechanisms 3 in this embodiment are arranged in pairs below the disk guiding and conveying mechanism 2 and extend from the front end to the tail end of the main frame 1. There is a guide rod channel 9 for the sunflower stems 29 to pass through between the paired feeding and weeding mechanisms 3. The guide rod channel 9 and the stem passing channel 7 are located in the same vertical plane. The feeding and weeding mechanism 3 is used to guide and straighten the sunflower stems 29 throughout the process to assist the automatic disk cutting of sunflowers, automatically break the residual sunflower stems 28, and automatically insert the sunflower disks 27 onto the sunflower stems 29 after cutting off the residual sunflower stems 28 from the sunflower disks 27, and the whole process is automated without manual participation;

[0033] At the same time, the stem cutting mechanism 4 and the residual stem breaking mechanism 5 are arranged end to end between the disk guiding and conveying mechanism 2 and the feeding and weeding mechanism 3 and are located directly below the stem passing channel 7. The cutting direction and the breaking direction are both perpendicular to the feeding direction of the disk guiding and conveying mechanism 2. The stem cutting mechanism 4 is used to initially cut the sunflower disks 27 from the plants, and then the residual stem breaking mechanism 5 breaks the residual sunflower stems 28 below the initially cut sunflower disks 27, so as to realize the automated operation of disk cutting;

[0034] In the middle of the end of the guiding and conveying mechanism, there is a plug tray groove 10 with an open rear end. The plug tray groove 10 is located directly above the guide rod channel 9. The plug tray mechanism 6 includes a plug tray telescopic rod 11. The plug tray telescopic rod 11 is arranged above the plug tray groove 10 with its telescopic end pointing to the plug tray groove 10. To ensure that the plug tray telescopic rod 11 can press the sunflower disk 27 against the remaining sunflower stalk 29, the telescopic distance of the plug tray telescopic rod 11 is greater than the maximum vertical distance between its end face and the cutting opening of the cutting mechanism. At the same time, the height of the front end of the plug tray groove 10 is higher than the height of the blade in the stalk cutting mechanism 4, and the height of the rear end is lower than the height of the blade in the stalk cutting mechanism 4. After the sunflower disk 27 of the cut disk is conveyed above the plug tray groove 10, the plug tray telescopic rod 11 is extended to press down the sunflower disk 27, realizing the automated operation of the cut disk, which is convenient and fast.

[0035] In this embodiment, to facilitate guiding the sunflower stalk 29 and the sunflower disk 27 into the feeding rod channel 7 and the guide rod channel 9, the front ends of both the disk guiding and conveying mechanism 2 and the feeding and threshing mechanism 3 extend outward in an outwardly flared shape.

[0036] Furthermore, as Figure 1 , Figure 2 , Figure 7 shown, the conveying table 12 in this embodiment successively includes an inlet guiding section 121, a platform conveying section 122, and a plug tray slideway conveying section 123 from front to back.

The platform conveying section 122 is horizontally arranged. The clamping and conveying track is located directly below the platform conveying section 122. The residual stalk breaking mechanism 5 is located below the plug tray slideway conveying section 123. The rear end of the plug tray slideway conveying section 123 slopes downward and extends to directly above the rear end of the feeding and threshing mechanism 3. The starting point of the plug tray groove 10 is located 5 - 25 cm, preferably 15 cm, above the plane where the cutting opening of the cutting mechanism is located.

[0037] Furthermore, as Figure 3 , Figure 4As shown, the clamping conveying track includes a clamping conveying chain 13 and a tightening guide plate 14 which are respectively arranged horizontally and relatively below the two conveying platforms 12. The clamping conveying chain 13 is driven by a clamping conveying motor 15 arranged on the main frame 1 and circulates in the plane where it is located. The tightening guide plate 14 is arranged on the main frame 1 through a spring telescopic component 16, preferably a spring telescopic component 16 with a guide rod, so as to ensure that the tightening guide plate 14 can move stably towards and away from the clamping conveying chain 13. The front end of the tightening guide plate 14 is connected to a residual rod guide plate 17, and the residual rod guide plate 17 moves away from the clamping conveying chain 13. One side of the conveying chain 13 extends to provide guidance for the sunflower stems 29 in the rod feeding channel 7, so that they can enter the clamping channel 8 and be clamped by the clamping conveying chain 13 and the tightening guide plate 14, so as to be cut by the stem cutting mechanism 4. A residual stem channel is reserved between the clamping conveying chain 13 and the tightening guide plate 14 for the residual stems of the sunflower to pass through. In the initial state, the width of the residual stem channel is smaller than the diameter of the residual stem 28 of the sunflower. The spring telescopic assembly 16 has the freedom to compress under the extrusion of the residual stem, thereby ensuring that the sunflower stem 29 is stably clamped after entering the clamping channel 8 to ensure the accurate implementation of the residual stem cutting work.

[0038] Further, such as Figure 1 , Figure 7 As shown, the feeding and plowing mechanism 3 includes a plowing device 18 and a plowing motor 19 which is transmission-connected to the plowing device 18. The plowing device 18 is arranged on the main frame 1 in a chain shape, and plowing claws are evenly distributed on the side of the chain. Driven by the plowing motor 19, the plowing direction of the plowing claws is the same as the extension direction of the feeding rod channel 7. In addition, the plowing claws between the two plowing devices 18 arranged in pairs are meshed with each other, and the space between the meshing plowing claws forms a guide rod channel 9 for directional conveying of the sunflower stalks 29 that have not been cut by the disc and the sunflower stalks 29 after being cut by the disc.

[0039] Further, such as Figure 2 , Figure 3 , Figure 4 As shown, the rod cutting mechanism 4 includes a cutting knife 20, and the cutting knife 20 is fixed on the main frame 1 below the clamping and conveying track through a cutting frame 21. The extension direction of the blade is perpendicular to the extension direction of the clamping channel 8. The cutting knife 20 is inclined forward of the cutting frame 21, and the blade is located in front of the cutting frame 21 to cut the conveyed sunflower stems 29 head-on.

[0040] In addition, in order to effectively remove the sunflower stem residues 28 under the sunflower disc 27 after the cutting disc, the stem residue tearing mechanism 5 in this embodiment includes a tearing knife 22, a pair of rollers and a tearing motor 23, such as Figure 7 , Figure 8 , Figure 9As shown, the tearing knife 22 is fixed on the bottom surface of the front end of the inserting disc slide conveying section 123, and the blade extends to the bottom of the end of the feeding rod channel 7, and the cutting direction of the blade is perpendicular to the extension direction of the feeding rod channel 7. The pair of rollers are symmetrically arranged on the left and right sides of the feeding rod channel 7, and the surface of the pair of rollers is provided with rubber sleeves. The upper end of the pair of rollers The rod feeding end is located below the end of the platform conveying section 122, and the lower end of the rod outlet end is located below the front end of the inserting disc slide conveying section 123. The minimum gap between the pair of rollers is smaller than the diameter of the sunflower residual stem 28, and the end face of the pair of rollers is parallel to the conveying plane of the inserting disc slide conveying section 123. The pair of rollers includes an active tearing wheel 24 and a driven tearing wheel 25, and the tearing motor 23 is connected to the active tearing wheel 24 in transmission. The corresponding setting of the pair of rollers and the tearing knife 22 can ensure that the sunflower stem residue 28 can enter the gap of the pair of rollers in time after the sunflower plate 27 and the sunflower stem residue 28 below it are transported out of the clamping conveying track. Under the drive of the tearing motor 23, the sunflower stem residue 28 is moved obliquely downward by the friction force between the pair of rollers, driving the sunflower plate 27 to move obliquely downward and contact the tearing knife 22. Under the action of the pair of rollers, the sunflower stem residue 28 is cut off by the tearing knife 22, and the sunflower plate 27 with the sunflower stem residue 28 removed slides down along the inserting plate slide conveying section 123 to the next workstation.

[0041] Further, such as Figure 5 As shown, the inserting plate mechanism 6 also includes an inserting plate pressing plate 26, the inserting plate telescopic rod 11 is vertically arranged above the inserting plate slot 10 through the inserting plate mounting frame 111, the upper end of the inserting plate pressing plate 26 is hinged to the top extension end of the inserting plate telescopic rod 11 through the hinge shaft and the hinge sleeve, and the lower end automatically droops to contact the inserting plate slideway conveying section 123, and the extension direction is the same as the direction of the feeding rod channel 7. The setting of the head end and the tail end of the inserting plate pressing plate 26 can block the sunflower plate 27 from which the sunflower residual stem 28 is taken out between the inserting plate pressing plate 26 and the inserting plate slideway conveying section 123. When the inserting plate telescopic rod 11 is extended, the sunflower plate 27 can be easily pressed automatically on the sunflower stem 29 at its inserting plate slot 10. Since the area of ​​the sunflower plate 27 is large, it can ensure that the sunflower plate 27 is inserted on the sunflower stem 29. The inserting plate telescopic rod 11 can be electric or pneumatic, and the staff can choose according to the actual situation. There is no specific limitation in this embodiment.

[0042] In this embodiment, the working process of the device is as follows:

[0043] The work vehicle equipped with the device travels along the direction of the ridges in the sunflower field. The reel 18 is driven by the reel motor 19 to rotate, and the sunflower heads 27 of the whole sunflowers are conveyed to the platform conveying section 122 through the conveying table 12. The cutting knife 20 cuts off the sunflower stalks 29. The sunflower heads 27 with the remaining sunflower stalks 28 are continuously conveyed backward by the clamping conveying track. When the remaining sunflower stalks 28 are conveyed to the gap between the pair of rollers, the remaining sunflower stalks 28 on the sunflower heads 27 are pulled and broken by the pulling knife 22 through the frictional force between the pair of rollers and the sunflower stalks 28. The sunflower heads 27 are conveyed to the chute of the chute inserting plate pressing plate 26 of the inserting plate chute conveying section 123. The inserting plate telescopic rod 11 extends, driving the inserting plate pressing plate 26 to move downward, pressing the sunflower heads 27 onto the sunflower stalks 29, and the functions of the sunflower cutting plate and the inserting plate are completed.

[0044] When it is necessary to cut and insert the plates of multiple rows of sunflowers simultaneously, the staff only needs to set the number of groups of the device and the spacing between each group of devices according to the actual operation range requirements, such as Figure 10 、 Figure 11 shown.
