A sunflower harvester is an agricultural machine specifically used for harvesting sunflowers. It can improve the efficiency of sunflower harvesting, reduce labor costs, and help ensure the integrity and quality of sunflower seeds. Before the sunflowers are harvested, it is necessary to manually cut off the sunflower heads and then insert them on the stems. After the sunflower heads and the sunflower seeds on them lose the nutrient transmission of the stems and are dried in the sun, they will gradually dry and be conducive to harvesting. At this time, the harvester can be used to harvest them.
[0003] However, the above-mentioned sunflower harvesters are generally large-scale mechanical equipment, which has many advantages in flat and large-scale plantations. However, in small-scale and geographically disadvantaged planting environments, manual harvesting is mostly used because the use limitations of large harvesters are more, or it is difficult to exert their functions. However, if manual harvesting is used, it will lead to low efficiency and occupy more labor.
[0004] Based on the above situation, it is necessary to design a sunflower harvester to solve the above problems. Summary of the Utility Model

Specific embodiments
[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.
[0023] Refer to Figures 1 - 5 As shown, a sunflower harvesting machine includes a movable frame 1. A number of material boxes 2 for containing sunflower flower heads are provided on the frame 1. It also includes several groups of collecting rods 3, a feeding mechanism for conveying the sunflower flower heads collected by the collecting rods 3 into the material boxes 2 on the frame 1, and a folding rod 4 for gathering the sunflower stems in front of the collecting rods 3 to be collected. Specifically, several groups of collecting rods 3 are connected to the frame 1 through a rotating shaft 301, and the rotating shaft 301 is rotatably connected to the frame 1. Each group of collecting rods 3 consists of two collecting rods 3 corresponding to each other in position. There is a certain distance between the two collecting rods 3, and this distance is the collecting channel 16 for collecting sunflower flower heads. And the width of the collecting channel 16 does not exceed the diameter size of the sunflower flower head to ensure that the sunflower flower head can be lifted during use. The input end of the feeding mechanism is located on one side of the collecting rod 3, the output end of the feeding mechanism extends to the material box 2 on the frame 1, and the folding rod 4 is located at the other side position of the collecting rod 3.
[0024] During use, by pushing the frame 1 forward, the receiving rod 3, the feeding mechanism, and the gathering rod 4 located on the frame 1 are driven to move. During the movement, the row of sunflower crops in the field is aligned between the gathering rod 4 and the receiving rod 3. The gathering rod 4 will gather the sunflower stems that are not in a straight line together, making them in a position corresponding to the receiving channel 16. Then, the rotating shaft 301 is driven to rotate, thereby driving several groups of receiving rods 3 connected to the rotating shaft 301 to rotate. When there are sunflower flower heads and sunflower stems to be harvested at the position of the receiving channel 16, the receiving rod 3 rotating around the rotating shaft 301 will pull out the sunflower flower heads from the sunflower stems and drive the sunflower flower heads to move together until they reach the input end position of the feeding mechanism. Under the action of gravity, the sunflower flower heads will fall onto the input end of the feeding mechanism, and then the feeding mechanism will transport the sunflower flower heads into the material box 2.
[0025] A second motor 14 is connected to the frame 1, and the output end of the second motor 14 is connected to the rotating shaft 301. By controlling the operation of the second motor 14, the rotational movement of the receiving rod 3 is controlled.
[0026] The gathering rod 4 is fixedly connected to the frame 1. There are two gathering rods 4, which are respectively located on both sides of the receiving rod 3. One end of the gathering rod 4 in the advancing direction of the frame 1 has a gradually increasing distance between the two gathering rods 4 from the end close to the receiving rod 3 to the other end. The end with a larger distance between the two gathering rods 4 will gather the sunflower stems within this range together, and then the sunflower stems will gradually shift to a position corresponding to the receiving channel 16 along the guidance of the gathering rod 4.
[0027] Refer to Figure 5 As shown, the feeding mechanism includes a ramp 5 connected to the frame 1. The ramp 5 gradually slopes downward from the end close to the receiving rod 3 to the other end. A through slot 6 corresponding to the receiving rod 3 is provided at the end of the ramp 5 close to the receiving rod 3. A blanking slot 7 is provided at the end of the ramp 5 far from the receiving rod 3. When the receiving rod 3 rotates and moves, under the action of the through slot 6, the receiving rod 3 can freely pass through the ramp 5. During this process, the sunflower flower heads will fall from the receiving rod 3 and onto the ramp 5. Since the ramp 5 has a certain inclination angle, the sunflower flower heads can slide along the ramp 5 until they reach the blanking slot 7 and are sent out from the blanking slot 7.
[0028] Further, the feeding mechanism further includes a bracket 8, a conveyor belt 9, and a driving assembly connected to the frame 1. Two rotating rollers 10 are rotatably connected to the bracket 8, and the conveyor belt 9 is sleeved on the two rotating rollers 10. The input end of the conveyor belt 9 corresponds to the output end of the blanking chute 7. The driving assembly is used to drive the rotating rollers 10 to rotate. The sunflower flower heads output from the output end of the blanking chute 7 will fall on the conveyor belt 9 corresponding to the blanking chute 7. Then, under the action of the driving assembly, the conveyor belt 9 will convey the sunflower flower heads above the material box 2 and drop them into the material box 2.
[0029] Among them, the driving assembly includes a pulley 11 connected to one end of the rotating roller 10 and a transmission belt 12 sleeved on the pulley 11. A first motor 13 is connected to the bracket 8, and the output end of the first motor 13 is connected to one of the pulleys 11. In use, by starting the first motor 13, the output end of the first motor 13 drives one of the pulleys 11 to rotate, and then drives the other pulley 11 to rotate through the transmission belt 12. Driven by the pulley 11, the two rotating rollers 10 will also rotate accordingly, and finally drive the conveyor belt 9 to run and rotate.
[0030] Refer to Figure 1 As shown, furthermore, since the frame 1 travels on the field and the road is uneven, when the conveyor belt 9 conveys the sunflower flower heads, it may fall midway. Therefore, vertical guard plates 15 are respectively connected to both sides of the output end of the conveyor belt 9 on the bracket 8. Under the action of the vertical guard plates 15, it is ensured that the sunflower flower heads can be smoothly conveyed to the material box 2.
[0031] In order to facilitate the movement of the frame 1, a number of traveling wheels 17 are provided under the frame 1. The movement of the frame 1 can be driven by manual pushing or by using electrical equipment, which will not be elaborated in detail.
[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
