Description

[0002] Sunflower is an economic crop with a huge domestic planting area. Currently, its harvesting machinery is mainly improved from combine harvesters such as corn and grain. The materials are transported by chain rakes. However, during the material transportation process, since the sunflower fruits are achenes, the peels are mostly black with white stripes and short hairs, the seeds are relatively fine and tender, easy to thresh, and the seed skin is easily damaged. Therefore, the sunflowers rub and collide with the mechanical mechanism, causing serious damage to the sunflower disk and seeds. Moreover, when the harvesting platform is harvesting sunflowers, the sunflower disk collides with the mechanical parts, resulting in seed threshing losses, and the overall practicality is poor.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) The present invention installs a gas blowing pipe and a gas sealing pipe on the straw divider of the harvesting platform. The gas blowing pipe ensures that the grains dropped on the straw divider tray can smoothly enter the auger. The gas sealing pipe on the left side of the straw divider tray blows air to close the gap between two adjacent straw divider trays, and blows the grains dropped in the gap onto the straw divider tray, thereby preventing the sunflower from colliding with the straw divider and causing the grains to fall from the gap, thereby reducing the loss of grains harvested by the harvesting platform.

The large flexible straw plowing plate plows the sunflower discs on the straw separation tray to avoid stagnation, and the small flexible straw plowing plate is set to plow the sunflower discs in the gap to avoid jamming and clogging, as well as blocking the air outlet of the gas sealing tube.

[0032] (3) A forced feeding mechanism is set between the discharge port of the auger feeding mechanism and the feed port of the spiral drum threshing mechanism. This mechanism can throw the sunflower disc backwards so that the sunflower disc quickly enters the threshing space and avoids accumulation at the feed port of the threshing device;

[0033] (4) The present invention adopts wind blowing to transport the fallen grains from the spiral drum threshing mechanism to the vibrating cleaning screen and then to the grain collecting box, thereby preventing the grains from being damaged by friction and collision with mechanical parts;

[0034] (5) The sunflower tray box of the present invention realizes the linkage between the side box cover and the inner turning piece through the hydraulic cylinder and the pull rod, so that when the side box cover is opened, the sunflower tray inside is turned out to achieve the purpose of automatic unloading;

[0035] (6) The present invention adopts mechanical drive such as chain drive and belt drive, which enhances the reliability and stability of the device;

[0036] In summary, the present invention provides an integrated cutting and stripping platform and a sunflower combine harvester, which can realize the integrated functions of separating, supporting, cutting, threshing, conveying, cleaning and packing; the sunflower seeds and debris are separated on the cutting platform, which effectively shortens the material conveying path and lays the foundation for the subsequent improvement of the cleaning quality.

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] The present invention is described in further detail below with reference to the examples.

[0057] Specific embodiment 1 of the integrated cutting and stripping header provided by the present invention:

[0058] like Figure 1-6 As shown, the integrated cutting and stripping header includes a header frame 1, on which are mounted a straw divider 2, a straw plow 3, a reciprocating cutter 4, an augers feeding mechanism 5, a spiral drum threshing mechanism 6, and a power transmission mechanism. The integrated cutting and stripping header is an improvement made in a public patent, the patent publication number of which is CN113079833B, and the invention name is "Combined sunflower combine harvester header threshing device", and the patent publication number is CN216650515U, and the invention name is "Sunflower harvesting device". This embodiment mainly improves the straw divider 2 and the straw plow 3, and the specific improvements are as follows:

[0059] The straw divider 2 includes several straw dividing trays 7 arranged side by side, and a gas sealing tube 8 is provided on the left side of each straw dividing tray 7. The front end of the gas sealing tube 8 is open and the rear end is blocked. An exhaust hole 9 is provided on the left side wall of the gas sealing tube 8. There is a 45° angle between the exhaust hole 9 and the axis of the gas sealing tube 8 to achieve blowing air obliquely to the rear. A gas blowing pipe 10 is fixed at the front end of the straw dividing tray 7, and the gas blowing pipe 10 is arranged along the front and rear directions. An engine 11 with an air compressor is provided on the harvester on which the cutting platform is installed. The air compressor of the engine 11 is respectively connected to the front ends of all the gas sealing tubes 8 and the front ends of all the gas blowing pipes 10 through air pipes, and the power output shaft of the engine 11 is connected to the power transmission mechanism.

[0060] The reeling device 3 includes a reeling cylinder 13, on which are mounted a plurality of rows of reeling plate assemblies, each row of reeling plate assemblies being arranged along the axial direction of the reeling cylinder 13, each row of reeling plate assemblies including a plurality of large flexible reeling plates 14 and small flexible reeling plates 15, wherein each small flexible reeling plate 15 is located between two adjacent large flexible reeling plates 14;

[0061] The large flexible reeling plate 14 corresponds to the reel separating tray 7 , and the small flexible reeling plate 15 corresponds to the gap between two adjacent reel separating trays 7 ; the power transmission mechanism drives the reeling cylinder 13 to rotate.

[0062] When harvesting sunflowers in the field, a hydraulic cylinder 16 is installed between the harvester frame 1 and the harvester frame. The harvester frame 1 can be lifted by the hydraulic cylinder 16 so that the harvester is raised or lowered to a height suitable for harvesting sunflowers; then as the harvester moves, the sunflower enters the harvester frame through the gap between the two adjacent straw trays 7, and then the straw plow 3 rotates to push it to the reciprocating cutter 4 on the rear side. In the process of the straw plow 3 pushing the sunflower, part of the grains that collide with the straw plow 3 and fall off fall onto the straw tray 7, and the other part will fall into the gap between the two adjacent straw trays 7. However, due to the setting of the gas sealing tubes 8 on the left and right sides of the straw tray 7, the gas is introduced into the gas sealing tubes 8 through the air compressor of the engine 11, so the gas in the gas sealing tubes 8 on both sides of the gap is in a blowing state, and the gap between the two adjacent straw trays 7 can be sealed by gas. , so that the grains will not fall from the gap, and the grains will be blown onto the grain-dividing tray 7. Preferably, a common pipe 90 is provided on the right side of the gas grain-dividing tray 7. The smooth curved pipe wall of the common pipe 90 is convenient for the entry of edible sunflowers. In addition, a gas blowing pipe 10 is provided at the front end of the separation tray. The gas blowing pipe 10 is mainly used for blowing gas backward to blow the grains backward. Preferably, the rear end 17 of the gas blowing pipe 10 is trumpet-shaped, so that the blown gas is divergent and has a wider range. Then, as the plowing device 3 rotates, the large flexible plowing plate 14 pokes the grains on the corresponding plowing tray 7, and the grains are plowed to the auger feeding mechanism 5. As a preferred embodiment, a number of small flexible plowing plates 15 are also installed on the plowing cylinder 13. The small flexible plowing plates 15 correspond to the gaps and are used to poke the sunflowers in the gaps so that they can smoothly enter the reciprocating cutter 4 to avoid sunflowers getting stuck in the gaps.

[0063] After the sunflowers are cut by the reciprocating cutter 4, the sunflower discs fall into the auger feeding mechanism 5. As the auger of the auger feeding mechanism 5 rotates, the sunflower discs enter the feed port of the spiral drum threshing mechanism 6 through the discharge port of the auger feeding mechanism 5, and then are threshed by the spiral drum threshing mechanism 6. Since there is a certain distance between the discharge port of the auger feeding mechanism 5 and the feed port of the spiral drum threshing mechanism 6, in order to avoid the accumulation of sunflower discs here, preferably, a forced feeding mechanism 18 is provided between the discharge port of the auger feeding mechanism 5 and the feed port of the spiral drum threshing mechanism 6. The forced feeding mechanism 18 includes a feeding shaft 19, which is rotatably mounted on the cutting table frame 1, and a plurality of feeding teeth 20 are fixed on the feeding shaft 19, and all the feeding teeth 20 are arranged side by side at intervals. The feeding shaft 19 is transmission-connected to the power transmission mechanism, and the sunflower discs can be thrown backwards by the rotating feeding teeth 20, so that the sunflower discs quickly enter the feed port of the spiral drum threshing mechanism 6.

[0064] Specific embodiment 2 of the sunflower combine harvester provided by the present invention:

[0065] like Figure 8-10As shown, the sunflower combine harvester in this embodiment includes the integrated harvesting header 100 of Example 1, and the specific structure also includes a harvester frame 21, on which are mounted a front air-blowing grain conveying system, a vibrating cleaning screen 22, a rear air-blowing grain conveying system, and a grain collecting box 25; the front air-blowing grain conveying system and the rear air-blowing grain conveying system both have a grain inlet and a grain outlet;

[0066] The grain outlet of the spiral drum threshing mechanism 6 is connected to the grain inlet of the front air-blowing grain conveying system, the grain outlet of the front air-blowing grain conveying system is located above the vibrating cleaning screen 22, and a cleaning fan 24 is installed in front of and below the vibrating cleaning screen 22. A grain outlet is provided at the lower part of the vibrating cleaning screen 22, and the grain outlet of the vibrating cleaning screen 22 is connected to the grain inlet of the rear air-blowing grain conveying system, and the grain outlet of the rear air-blowing grain conveying system is connected to a grain collecting box 25;

[0067] The power transmission mechanism is used to drive the front air-blowing seed conveying system, the vibrating cleaning screen 22 and the rear air-blowing seed conveying system to work respectively.

[0068] In order to reduce the collision between the grains and the conveying mechanical mechanism during the conveying process, the present embodiment adopts an air-blowing conveying mechanism for conveying. The specific grain conveying process is as follows: after the spiral drum threshing mechanism 6 thres the sunflower disc, the grains are blown to the vibrating cleaning screen 22 by the front air-blowing seed conveying system. The vibrating cleaning screen 22 is an existing conventional technology. The grains can be cleaned by the vibrating cleaning screen 22. The grains fall to the grain outlet through the screen surface of the vibrating cleaning screen 22, and the cleaning fan 24 blows away the lighter impurities and dust. Preferably, a plurality of rows of serrated push plates 23 are installed on the screen surface of the vibrating cleaning screen 22. During the vibration process of the vibrating cleaning screen 22, the serrated teeth on the serrated push plates 23 can be used to push the impurities on the screen surface to one side of the vibrating cleaning screen 22.

[0069] After the vibrating cleaning screen 22 cleans the grains, the grains fall into the post-air-blowing grain conveying system, and then the post-air-blowing grain conveying system blows the grains to the grain collecting box 25.

[0070] In order to realize the air blowing and conveying function of the front air blowing type seed conveying system and the rear air blowing type seed conveying system, the front air blowing type seed conveying system includes a front spiral seed conveyor 26, a front seed air conveying pipe 27 and a front seed conveying fan 28. Figure 15As shown, the feed port of the front spiral grain conveyor 26 is connected to the grain outlet of the spiral drum threshing mechanism 6, and the power transmission mechanism drives the front spiral grain conveyor 26 to work; the lower end of the front grain air conveying pipe 27 is provided with an air inlet and a front grain inlet, the discharge port of the front spiral grain conveyor 26 is connected to the front grain inlet of the front grain air conveying pipe 27, the front grain conveying fan 28 is connected to the air inlet of the front grain air conveying pipe 27, and the upper end outlet of the front grain air conveying pipe 27 is located above the vibrating cleaning screen 22; the upper end outlet of the front grain air conveying pipe 27 is provided with a port baffle 29.

[0071] After the spiral drum threshing mechanism 6 thres the sunflower disc, the seeds enter the front spiral seed conveyor 26. Under the front spiral seed conveyor 26, the seeds enter the front seed air delivery duct 27 through the front seed inlet. The front seed delivery fan 28 then blows air into the front seed air delivery duct 27, using wind energy to blow the seeds to the upper end of the front seed air delivery duct 27. From there, the seeds fall onto the screen surface of the vibrating cleaning screen 22. The provision of the port baffle 29 ensures that the seeds fall onto the vibrating cleaning screen 22, preventing them from being blown to other locations.

[0072] The rear air-blowing grain conveying system includes a rear spiral grain conveyor 30 and a rear grain air conveying pipe 31. The grain outlet of the vibrating screening screen 22 is connected to the feed port of the rear spiral grain conveyor 30, and the power transmission mechanism drives the rear spiral grain conveyor 30 to work; the lower end of the rear grain air conveying pipe 31 is provided with a rear grain conveying fan 32 and a rear grain inlet, the discharge port of the rear spiral grain conveyor 30 is connected to the rear grain inlet of the rear grain air conveying pipe 31, and the upper end outlet of the rear grain air conveying pipe 31 is connected to the grain collecting box 25.

[0073] After the vibrating cleaning screen 22 screens the grains, the grains enter the rear spiral grain conveyor 30. Under the conveyance of the rear spiral grain conveyor 30, the grains enter the rear grain air delivery duct 31 through the rear grain inlet. The rear grain delivery fan 32 blows air into the rear grain air delivery duct 31, and the wind energy blows the grains to the upper end of the rear grain air delivery duct 31, and the grains enter the grain collection box 25 from this end.

[0074] The grains are transported from the spiral drum threshing mechanism 6 to the vibrating cleaning screen 22 and then to the grain collecting box 25 by wind blowing, which can avoid the grains from being damaged by friction and collision with mechanical parts.

[0075] Specific embodiment 3 of the sunflower combine harvester provided by the present invention:

[0076] The difference from specific embodiment 2 is that, Figure 11-14As shown, a sunflower tray lower conveying trough device 33, a sunflower tray upper conveying trough device 34 and a sunflower tray collecting box 35 are also installed on the harvester frame 21; the sunflower tray lower conveying trough device 33, the sunflower tray upper conveying trough device 34 and the sunflower tray collecting box 35 are mainly used to collect and process the sunflower trays after they fall off. Specifically, the sunflower tray outlet of the spiral drum threshing mechanism 6 is connected to the feed end of the sunflower tray lower conveying trough device 33, the discharge end of the sunflower tray lower conveying trough device 33 is connected to the feed end of the sunflower tray upper conveying trough device 34, and the discharge end of the sunflower tray upper conveying trough device 34 is connected to the sunflower tray collecting box 35; the power transmission mechanism is used to drive the sunflower tray lower conveying trough device 33 and the sunflower tray upper conveying trough device 34 to work.

[0077] The upper conveying trough device 34 of the sunflower tray and the lower conveying trough device 33 of the sunflower tray both include a double-row conveying chain 36. A number of scrapers 37 are fixed on the two chains of the double-row conveying chain 36. All the scrapers 37 are arranged side by side at intervals. A support plate 38 is also installed on the frame of the double-row conveying chain 36. The support plate 38 is located below the chain of the double-row conveying chain 36. The support plate 38 is mainly used to support the sunflower tray.

[0078] After threshing, the sunflower discs enter the sunflower disc lower conveying trough device 33 through the sunflower disc outlet of the spiral drum threshing mechanism 6. With the transmission of the double-row conveying chain 36, the scraper 37 lifts and pushes the sunflower discs upward, and then passes from the sunflower disc lower conveying trough device 33 to the sunflower disc upper conveying trough device 34. With the transmission of the double-row conveying chain 36 of the sunflower disc upper conveying trough, the sunflower discs are conveyed to the sunflower disc collection box 35.

[0079] As a preferred embodiment, in order to realize the automatic unloading function of the sunflower tray collection box 35, as shown in FIG. Figure 16 As shown, the sunflower tray collection box 35 in this embodiment includes a box frame 39, in which a side box cover 40, an inner flip piece and two side box panels are installed. The two side box panels are located on opposite sides, and the side box cover 40 and the inner flip piece are located on opposite sides. The upper end of the side box cover 40 is mounted on the box frame 39 by a hinge, and two connecting rods 41 are fixed to the side box cover 40. A hydraulic cylinder 42 is installed between the top of the box frame 39 and the two connecting rods 41.

[0080] The inner flip part is an L-shaped structure, and the inner flip part includes a vertical plate body 43 and a bottom plate body 44. The bottom plate body 44 is located at the bottom of the box frame body 39, and one end of the bottom plate body 44 is hinged to the box frame body 39. The vertical plate body 43 is located on the opposite side of the side box cover 40. Two pull rods 45 are connected between the vertical plate body 43 and the side box cover 40, and the two ends of the pull rods 45 are respectively hinged to the vertical plate body 43 and the side box cover 40.

[0081] The box frame body 39 is closed by the side box cover 40, the vertical plate body 43, the bottom plate body 44 and the two side box plates, and the top is open for receiving the sunflower trays. When the sunflower trays in the sunflower tray collection box 35 need to be unloaded, the two groups of hydraulic cylinders 42 are started, and the side box cover 40 is pulled by the hydraulic cylinder 42 through the connecting rod 41, and the side box cover 40 is rotated to open. At the same time, the side box cover 40 pulls the inner flip part through the pull rod 45, so that the inner flip part rotates, and the inclined inner flip part pushes the sunflower tray to the opening of the side box cover 40. Under the action of gravity, the sunflower tray can fall through the gap opened by the side box cover 40, and a collection truck can be placed below the fallen part to collect and transport the sunflower trays.
