[0002] The main sunflower producing areas in my country, such as Xinjiang and Inner Mongolia, have a special climatic environment and the growth characteristics of sunflowers themselves, which leads to a high moisture content in the sunflowers waiting to be harvested. In addition, the drying space is limited. Therefore, after accumulating years of farming experience, the above-mentioned areas have formed the current way of harvesting sunflowers: first cut off the sunflower discs that have entered the harvest period, then cut the sunflower stalks into pointed shapes from the middle, and then insert the sunflower discs into the sunflower stalks. After the discs are inserted and dried for four to seven days, the sunflower discs can be harvested.

[0003] At present, the harvest of edible sunflowers in trays is partly carried out by manually removing the trays and then threshing them. This method is labor-intensive and has low harvesting efficiency; some people use edible sunflower threshing harvesters, but the existing edible sunflower harvesters have problems such as grains spilling when removing the trays from the sunflower stalks, incomplete collection, grain loss, and unnecessary waste.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the present invention involves directional indications. If the specific posture changes, the directional indication will also change accordingly. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0030] Combination Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an in-situ threshing harvester for sunflowers with a tray, comprising a frame 1 and a power input roller 2 arranged on the frame 1 and drivingly connected to a power output shaft; the frame 1 is provided with a grain divider 3, a seed-falling prevention feeding mechanism 4, a sunflower seed threshing mechanism 5, a sunflower tray knocking mechanism 6, a tray mechanism 8 and a sunflower seed collecting mechanism;

[0032] B. The anti-seed-dropping feeding mechanism 4 is arranged at the rear of the grain divider 3, and is used to place the sunflower disc face upward on the tray mechanism 8, and prevent the sunflower seeds from scattering;

[0033] C. The tray mechanism 8 is arranged at the rear of the anti-seed-dropping feeding mechanism 4 and is used to hold the sunflower tray;

[0034] D. The sunflower seed threshing mechanism 5 and the sunflower plate knocking mechanism 6 are sequentially arranged above the rear of the anti-seed falling feeding mechanism 4, and both use the power input roller 2 as the power driving source. The sunflower seed threshing mechanism 5 is used to loosen the sunflower seeds on the sunflower plate; the sunflower plate knocking mechanism 6 is used to knock the sunflower plate to make the sunflower seeds on the sunflower plate fall off to the sunflower seed collecting mechanism;

[0035] E. The sunflower seed collecting mechanism is used to collect sunflower seeds.

[0036] In this embodiment, an in-situ threshing harvester for eating sunflowers with a tray of the present invention is provided. When in use, the straw divider 1 guides the sunflower stems into the anti-drop seed feeding mechanism 4, and the anti-drop seed feeding mechanism 4 prevents the seeds of the sunflower plates on the sunflower stems passing by from falling to the ground. At the same time, the sunflower plates on the sunflower stems are supported upward by the tray mechanism 8, and are loosened by the sunflower seed threshing mechanism 5 and knocked by the sunflower plate knocking mechanism 6 in turn, so that the sunflower seeds on the sunflower plates fall off, and the sunflower seeds on the sunflower plates fall into the sunflower seed collecting mechanism. The in-situ threshing harvester for eating sunflowers with a tray of the present invention can not only guide the sunflower stems to perform in-situ threshing in the state of inserting the tray of eating sunflowers without taking the tray through the straw divider 1, but also can ensure that the sunflower plates on the sunflower stems are placed upward on the tray mechanism through the anti-drop seed mechanism, and the scattered sunflower seeds fall into the sunflower seed collecting mechanism, so as to achieve the goal of efficient, energy-saving and low-loss threshing of the sunflower with a tray of the present invention.

[0037] For A, combined Figure 1 As shown, preferably, the straw divider 3 may optionally but is not limited to include a left straw divider disposed on the left side of the frame 1 and a right straw divider disposed on the right side of the frame 1, the two being spaced a certain distance apart so that the sunflower stems enter between the two and guide the sunflower stems into the subsequent anti-seed falling feeding mechanism 4.

[0038] For B, combined Figure 3 As shown, preferably, the anti-drop seed feeding mechanism 4 may optionally include, but is not limited to, a left support plate 41 and a right support plate 42, the front end of which is lower than the rear end and is tilted and arranged on the left and right sides of the frame 1, a plurality of fan-shaped baffles 43 and a reset member 44, wherein the plurality of fan-shaped baffles 43 are stacked on the left support plate 41 and the right support plate 42 and can be rotated to both sides, and the rotation position is reset by the reset member 44. In this embodiment, the front end of the anti-drop seed feeding mechanism is lower than the rear end and is tilted and arranged on the frame 1, so as to straighten the sunflower stems with different inclinations and make the sunflower discs inserted on the sunflower stems face upward horizontally.

[0039] More specifically, the left support plate 41 and the right support plate 42 are provided with guide grooves respectively, and a plurality of fan-shaped baffles 43 are respectively stacked and riveted downward from the front end to the rear end in the guide grooves, and one end riveted to the guide groove is fixed to the reset member 44, and the fan-shaped baffles are rotated under the reset action of the reset member 44. More specifically, the reset member 44 is optionally but not limited to a torsion spring, and the fan-shaped baffles are rotated and reset under the torsion action of the torsion spring.

[0040] In this embodiment, a preferred embodiment of the anti-drop seed feeding mechanism 4 is provided, and the plurality of fan-shaped baffles 43 on the left support plate 41 and the right support plate 42 are closed when no sunflower stalks are passed. When the sunflower stalks are fed into the anti-drop seed feeding mechanism 4 through the straw divider 3, the fan-shaped baffles 43 are first contacted. Under the action of the forward inertia of the harvester, the fan-shaped baffles 43 on both sides are opened one by one, respectively, so that the sunflower tray on the sunflower stalk is placed on the tray mechanism 8 with the tray face upward, and moves toward the rear end of the harvester. After the sunflower stalks pass through, the fan-shaped baffles 43 on both sides are closed one by one. In other words, the fan-shaped baffles 43 are opened only when the sunflower stalks pass through, so the seeds on the fan-shaped baffles 43 are continuously moved toward the rear end by the centrifugal force and the thrust, and fall into the sunflower seed collecting mechanism at the rear end, which can effectively prevent the sunflower seeds on the sunflower tray on the sunflower stalks passing through from falling to the ground.

[0041] More preferably, the spacing distance at the front end between the left support plate 41 and the right support plate 42 is greater than the spacing distance at the rear end; more preferably, the front ends of the left support plate 41 and the right support plate 42 are lower from the ground, and the rear ends are higher from the ground; that is, the front end spacing distance between the left support plate 41 and the right support plate 42 is wider and lower from the ground, and the rear end spacing is narrower and higher from the ground, which facilitates the straightening of sunflower stalks of different uprightness and heights and the smooth landing of the sunflower disc with the front side facing upward on the tray mechanism 8.

[0042] For C, combined Figure 4 As shown, preferably, the tray mechanism 8 may optionally but not limited to include connecting pipes 81 spaced apart on the left and right sides of the frame, pneumatic springs 82 are provided on the connecting pipes 81 on both sides, and a supporting plate 83 is provided on the upper part of the pneumatic spring 82. In this embodiment, a preferred embodiment of the tray mechanism 8 is given, and a space for sunflower stems to pass through is left between the connecting pipes 81 on both sides. When the sunflower tray is transported backward from the anti-drop seed feeding mechanism 4, the sunflower tray is supported by the supporting plates 83 on both sides, and the sunflower seed threshing mechanism 5 provided on the upper part of the supporting plate 83 exerts a certain pressure on the sunflower tray, and the pneumatic spring is compressed according to the thickness and weight of the sunflower tray. More preferably, pneumatic springs 82 are respectively provided on the front and rear of the connecting tubes 81 on both sides, and the support plate 83 on the front pneumatic spring 82 is lower than the support plate 83 on the rear pneumatic spring 82, including but not limited to setting the front pneumatic spring 82 and the rear pneumatic spring 82 to be perpendicular to the connecting tube 81, but the distance of the front pneumatic spring 82 is shorter than that of the rear pneumatic spring 82. In this embodiment, Figure 4 As shown, the pneumatic spring 82 at the front of the connecting tube 81 is inclined toward the front end at a certain angle, so that the pneumatic spring 82 at the front end is lower than the pneumatic spring 82 at the rear end, and the pneumatic spring 82 at the rear of the connecting tube 81 is perpendicular to the connecting tube 81. When the front support plate 83 receives the sunflower disc, the pneumatic spring 82 at the front end is pressed down to adapt to the feeding of sunflower discs of different thicknesses.

[0043] For D, combined Figure 5As shown, preferably, the sunflower seed threshing mechanism 5 may include, but is not limited to, a hollow discrete roller 51, a shaft discrete roller 52, and a sleeve 53 for separating the two, and the surface of the hollow discrete roller 51 and the shaft discrete roller 53 are provided with a grain loosening tooth 54. In this embodiment, the hollow discrete roller 51 and the shaft discrete roller 52 are nested and combined through the sleeve 53, and the power input roller 2 may transmit two power sources with opposite movement directions to the hollow discrete roller 51 and the shaft discrete roller 52, respectively, so that the movement directions of the two are opposite. More preferably, the grain loosening tooth 54 may be formed by three-dimensional printing, but is not limited to being arranged obliquely on the hollow discrete roller 51 and the shaft discrete roller 52. The sunflower plate is supported by the support plate 8, and the surface of the sunflower plate is rotated in opposite directions by the hollow discrete roller 51 and the shaft discrete roller 52. Since the grain loosening teeth 54 are arranged obliquely, the sunflower plate will be subjected to opposite forces, and the sunflower plate grains will be effectively loosened, which is convenient for subsequent threshing.

[0044] Combination Figure 6 As shown, the sunflower plate knocking mechanism 6 may optionally include, but is not limited to, a knocking roller 61, a connecting seat 62 disposed on the knocking roller 61, and a knocking rod 63 disposed on the connecting seat 62. The connecting seat 62 is fixed on the knocking roller 61, and the knocking rod 63 may be optionally fixed on the connecting seat 62, so that the sunflower plate is threshed cleanly, but there is a risk of damaging the sunflower seeds. In this embodiment, the knocking rod 63 is connected to the connecting seat 62 by a latch and can rotate around the latch, ensuring that the sunflower plate is threshed cleanly without damaging the sunflower seeds.

[0045] Preferably, the sunflower in-situ threshing harvester with a tray of the present invention may also optionally include, but not limited to, a tray surface seed cleaning mechanism 7 for cleaning the sunflower seeds on the tray; specifically, Figure 1 As shown, the disk surface seed cleaning mechanism 7 is arranged at the rear of the sunflower disk knocking mechanism 6, and can optionally but not limited to include a rotatable cleaning rod and a cleaning brush arranged on the cleaning rod. Specifically, the cleaning roller can optionally but not limited to be connected to the power input rod 2 to be driven by the power input rod 2 to rotate.

[0046] For E, sunflower seed collection agencies, such as Figure 2 As shown, the optional but not limited to include a seed collection hopper 91 disposed below the tray mechanism 8, a grain conveying pipe 92 connected to the lower part of the seed collection hopper 91, and a grain collection box 94 disposed at the outlet of the grain conveying pipe 92, wherein a grain conveying auger 93 driven by an auger driving unit is disposed in the grain conveying pipe 92, the auger driving unit is connected to an auger flexible shaft through a coupling, and the grain conveying auger 93 is connected to the auger flexible shaft. The seed collection hopper 91 collects the sunflower seeds at the rear end of the anti-seed feeding mechanism 4, the sunflower seeds dropped during the loosening of the sunflower disc by the sunflower seed threshing mechanism 5, the sunflower seeds dropped when the sunflower disc knocking mechanism 6 knocks the sunflower disc, and the sunflower seeds dropped from the sunflower disc by the subsequent disc surface grain cleaning mechanism 7, and the sunflower seeds in the seed collection hopper 91 are transported to the grain collection box 94 through the grain conveying auger 93 in the grain conveying pipe 92.

[0047] As a further preferred embodiment, the sunflower in-situ threshing harvester with a tray of the present invention further includes a sunflower stalk guide roller 10 for guiding the sunflower stalks so that the sunflower tray surface falls on the tray mechanism 8. The sunflower stalk guide roller 10 is arranged below the tray mechanism 8 and is connected to the vehicle body ground wheel through a chain transmission. Figure 1 As shown, the sunflower stalk guide roller 10 is a spiral structure. Before the sunflower stalks are discharged from the anti-seed-dropping feeding mechanism 4, in order to ensure that the sunflower discs on the sunflower stalks are smoothly transported to the support plate 83 of the tray mechanism 8, the sunflower stalks are driven by the sunflower stalk guide roller 10 to move the sunflower discs, and the sunflower stalks are driven to move backward by the rotation of the sunflower stalk guide roller 10. In this embodiment, the sunflower stalk guide roller 10 is connected to the vehicle body ground wheel through a chain, so that the rotation speed of the sunflower stalk guide roller 10 matches the forward speed of the vehicle body.

[0048] As a further preferred embodiment, it also includes a seed-dropping prevention mechanism, which includes a seed-dropping prevention fan 111, an exhaust port 113 provided on the connecting pipe 81, and an air pipe 112 connected to the air outlet of the seed-dropping prevention fan 111 and the exhaust port 113. Figure 1 As shown, in this embodiment, the exhaust port 113 on the connecting pipe 81 is two rows of evenly distributed air holes, and the airflow discharged from the air holes blows the sunflower seeds dropped from the sunflower seed threshing mechanism 5, the sunflower disc knocking mechanism 6 and the disc surface seed cleaning mechanism 7 into the seed collection hopper 91, preventing the sunflower seeds from falling to the two outer sides of the frame and reducing the loss of seeds falling to the ground.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
