Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a single-plant harvesting device for yellow alfalfa. Background Art

[0002] Alfalfa is an important forage crop, widely used in animal husbandry and grassland protection. In the planting and management of alfalfa, single-plant harvesting is a key operation, which can be used to collect samples of different parts of alfalfa, such as seeds, leaves, and stems, for research and analysis. Traditional single-plant harvesting of alfalfa usually uses manual operation or simple tools, which has low work efficiency. In addition, during the alfalfa harvesting process, alfalfa is harvested in multiple stubbles, and the stubble height is different each time it is harvested, resulting in the inability of existing harvesting tools to be adaptively adjusted according to the harvesting height. To this end, we propose a device for single-plant harvesting of alfalfa. Utility Model Content

DETAILED DESCRIPTION

[0019] Example

[0020] See also Figure 1-4 , the utility model provides a technical solution:

[0021] A device for harvesting alfalfa single plant, wherein a wheel 13 is hingedly installed at the lower end of a frame 1, so as to facilitate the movement of the frame 1. Two groups of vertically distributed screw rods A2 are inserted on the surface of the frame 1, and two groups of motors A3 are fixedly connected to the upper end surface of the frame 1, and the output shafts of the two groups of motors A3 are respectively connected to the two groups of screw rods A2 for transmission. At the same time, two groups of guide rods 14 are fixedly connected to the surface of the frame 1, and the two groups of guide rods 14 are respectively located on one side of the two groups of screw rods A2, and the guide rods 14 and the screw rods A2 are distributed in parallel, and sliders A6 are installed on the surfaces of the screw rods A2 and the guide rods 14, and harvesting mechanisms 7 are installed on the surfaces of the two groups of sliders A6, and the harvesting mechanisms 7 are used for automatically cutting and harvesting alfalfa single plants. And by running the motor A3, the screw rod A2 is driven to rotate, and the slider A6 can be controlled to slide linearly along the guide rod 14, and the height of the harvesting mechanism 7 can be further adjusted, so that the harvesting mechanism 7 can retain different stubble heights when harvesting alfalfa individually, further improving the applicability of the device.

[0022] The harvesting mechanism 7 includes a lifting frame 701 installed on the surface of two groups of harvesting mechanisms 7, a mounting frame 714 is fixedly connected to the center of the surface of the lifting frame 701, a motor D715 is fixedly connected to the surface of the mounting frame 714, and a cutting blade 716 is fixedly connected to the output shaft of the motor D715. When the height adjustment of the harvesting mechanism 7 is completed, the motor D715 is turned on to drive the cutting blade 716 to swing back and forth. The cutting blade 716 is set to be double-sided, so that the cutting blade 716 can quickly cut the bottom of the yellow lucerne single plant, so as to achieve the overall harvest of the yellow lucerne single plant.

[0023] The surface of the lifting frame 701 is sleeved with a fixed seat 702, the surface of the fixed seat 702 is fixedly connected with a side plate 703, the outer surface of the side plate 703 is fixedly connected with a motor C704, the output shaft of the motor C704 passes through the other side of the side plate 703 and is fixedly connected with a driving pulley 705, the surface of the side plate 703 away from the driving pulley 705 is fixedly connected with a fixed shaft 706, the surface of the fixed shaft 706 is sleeved with a driven pulley 707, and a feeding belt 708 is sleeved and installed between the driving pulley 705 and the driven pulley 707. After the motor C704 is turned on, the driving pulley 705 is driven to connect with the feeding belt 708 and the driven pulley 707 for transmission. The conveyor belt 708 is located below the cutting blade 716, so that the yellow alfalfa plant cut by the cutting blade 716 will fall on the surface of the conveyor belt 708. The yellow alfalfa plant can be transmitted to one side of the frame 1 by the rotation of the conveyor belt 708. A gap is left between the conveyor belt 708 and the lifting frame 701. The surface of the frame 1 is fixedly connected with a receiving plate 10, and the receiving plate 10 is located below the gap between the conveyor belt 708 and the lifting frame 701, so that the conveyor belt 708 can further transfer the cut yellow alfalfa plant to the receiving plate 10 for collection. The surface of the frame 1 is fixedly connected with a collection box 11, and the collection box 11 is located at the rear side of the receiving plate 10. The collection box 11 is fixedly connected with a negative pressure fan 12. When the negative pressure fan 12 is turned on, a negative pressure is formed at the inlet of the collection box 11, so that the yellow alfalfa plant falling on the surface of the receiving plate 10 is sucked into the collection box 11 for automatic storage.

[0024] Two sets of side panels 703 are installed on the surface of the lifting frame 701, and two sets of feed belts 708 installed on the two sets of side panels 703 are symmetrically distributed. At the same time, threaded holes are provided on the surface of the fixing seat 702, and fixing bolts 710 are inserted into the threaded holes. The fixing seat 702 slides on the surface of the lifting frame 701 to further adjust the installation position of the feed belt 708 on the lifting frame 701, and adjust the spacing between the two sets of feed belts 708. Further, when the harvesting mechanism 7 harvests the yellow alfalfa single plant, it can be adjusted according to the size of the yellow alfalfa single plant, and ensure that the yellow alfalfa single plant cut by the cutting blade 716 can stably fall to the surface of the feed belt 708, and be transferred to the receiving plate 10 by the feed belt 708 for collection. The surface of the conveyor belt 708 is provided with convex strips 709 which are distributed linearly at equal distances, so that when the conveyor belt 708 is conveying individual alfalfa plants, the convex strips 709 increase the friction between the individual alfalfa plants and the conveyor belt 708, further preventing the individual alfalfa plants from slipping on the surface of the conveyor belt 708, resulting in low conveying efficiency.

[0025] The upper surfaces of both sides of the side panel 703 are fixedly connected with protrusions 711, a connecting shaft 712 is inserted between the two groups of protrusions 711, and a side baffle 713 is hinged on the surface of the connecting shaft 712. The side baffle 713 can prevent the cutting blade 716 from cutting the individual alfalfa plants and causing the individual alfalfa plants to fall from both sides of the side panel 703.

[0026] A screw rod B4 is inserted on the surface of the frame 1, and a motor B5 is fixedly connected to the surface of the frame 1. The output shaft of the motor B5 is in transmission connection with the screw rod B4. A slider B8 is installed on the surface of the screw rod B4 and the guide rod 14. A pressing plate 9 is fixedly connected to the surface of the slider B8. The pressing plate 9 is located above the harvesting mechanism 7. When the harvesting mechanism 7 is cutting and harvesting a single plant of yellow alfalfa, the motor B5 is turned on to drive the screw rod B4 to rotate, and the slider B8 is further controlled to slide linearly on the surface of the guide rod 14 to adjust the height of the pressing plate 9 relative to the harvesting mechanism 7. When the harvesting mechanism 7 is cutting and harvesting a single plant of yellow alfalfa, the pressing plate 9 can press down on the top of the single plant of yellow alfalfa, further shaking off the moisture on the single plant of yellow alfalfa, thereby improving the harvesting effect of the single plant of yellow alfalfa.

[0027] In addition, a torsion spring is installed inside the connecting shaft 712. Under the action of the torsion spring inside the connecting shaft 712, the side baffle plate 713 is always pushed toward the side of the pressure plate 9 to rotate, so that when the pressure plate 9 slides up and down, the side baffle plate 713 can always contact the surface of the pressure plate 9, further effectively preventing the harvested alfalfa from falling.
