A protective cover (not shown for ease of display) located on the surface of the transmission structure is fixedly connected to the back of the front frame 4 by bolts.
[0018] refer to Figure 4 The rear box 1 has packaging outlets on both the front and rear sides on the lower right side, and the packaging outlets are connected to a packaging bag fitting opening 16 on the right side. The surface of the packaging bag fitting opening 16 is provided with a rubber layer and the surface of the rubber layer is provided with anti-slip texture.
[0019] This embodiment utilizes the design of a baling outlet and a baling bag fitting opening 16 on the lower right side of the rear box 1 to facilitate the direct baling of harvested alfalfa transported to the rear box 1. The rubber layer and anti-slip texture on the surface of the baling bag fitting opening 16 ensure that the baling bag is securely fitted onto the opening, preventing the baling bag from slipping during the baling process. This ensures that the alfalfa can be accurately packed into the baling bag, improving the success rate and efficiency of baling and guaranteeing the smooth progress of the alfalfa baling operation.
[0020] refer to Figure 1 The top of the rear box 1 is provided with a cleaning groove, and the left side of the inner wall of the cleaning groove is hinged with a closed door 17 by a shaft. The closed door 17 is in contact with the inner wall of the cleaning groove on all four sides.
[0021] This embodiment facilitates internal cleaning of the device through the cleaning groove and the closed door 17 opened at the top of the rear box 1. After the device has been used for a long time, alfalfa residue and other debris may accumulate inside the rear box 1. By opening the closed door 17, the inside of the rear box 1 can be easily cleaned, avoiding the accumulation of debris from affecting the normal operation of the device, keeping the inside of the device clean, and extending the service life of the device.
[0022] refer to Figure 5 A sealing magnetic strip 18 located below the cleaning groove is fixedly connected to the top of the inner wall of the rear box 1. The top of the sealing magnetic strip 18 is magnetically connected to the bottom of the closed door 17.
[0023] In this embodiment, by setting the sealing magnetic strip 18 at the top of the inner wall of the rear housing 1 to be magnetically connected to the bottom of the closed door 17, it can ensure that the closed door 17 fits tightly against the inner wall of the cleaning tank when closed, forming a good sealing effect. This prevents alfalfa debris, dust, etc. from leaking out of the cleaning tank during the operation of the device, ensuring the cleanliness of the working environment and avoiding the impact of debris leakage on people and equipment around the device. At the same time, it also helps to maintain the internal sealing of the device and improve the overall performance of the device.
[0024] refer to Figure 1 An arc-shaped splash guard 19 is fixedly connected to the top left side of the front frame 4. The left end of the arc-shaped splash guard 19 extends to the left side of the top of the harvesting roller 8. The bottom of the drive motor 14 is fixedly connected to the top of the arc-shaped splash guard 19.
[0025] This embodiment effectively prevents alfalfa debris, soil, and other contaminants from splashing out during harvesting by setting an arc-shaped splash guard 19 on the top left side of the front frame 4. Its left end extends to the left side of the top of the harvesting roller 8, expanding the protection range and protecting equipment such as the drive motor 14 from damage by splashes, thus extending the service life of the equipment. Simultaneously, the drive motor 14 is fixed to the top of the arc-shaped splash guard 19, making the device structure more compact and the space utilization more efficient.
[0026] refer to Figure 6 Several evenly distributed inclined rods 20 are fixedly connected to the top left side of the inner wall of the rear box 1. The bottom end of the inclined rods 20 is inclined to the right, and the inclined rods 20 are staggered with the nail teeth 13 on the surface of the conveying roller 11.
[0027] In this embodiment, the inclined insertion rod 20 on the top left side of the inner wall of the rear box 1 is staggered with the nail teeth 13 on the surface of the agitator conveyor roller 11. When the agitator conveyor roller 11 conveys alfalfa into the rear box 1, the inclined insertion rod 20 can comb and disperse the alfalfa, preventing the alfalfa from tangling and piling up during the conveying process. This allows the alfalfa to be more evenly distributed in the rear box 1, facilitating subsequent packing work and ensuring the quality and effect of packing.
[0028] refer to Figure 2 The rear side of the front frame 4 is fixedly connected to a protective plate 21 located between the transmission belt and the harvesting roller 8. The bottom left and right sides of the protective plate 21 are provided with round holes. The rear surfaces of the first rotating shaft 7 and the second rotating shaft 10 are rotatably connected to the inner walls of the two round holes through bearings.
[0029] This embodiment effectively isolates the transmission belt and the harvesting area by installing a protective plate 21 on the rear side of the front frame 4, located between the transmission belt and the harvesting roller 8. This prevents alfalfa from contacting the transmission belt, ensuring smooth operation of the transmission belt and guaranteeing the stability and reliability of the alfalfa harvesting and baling device, thus improving operational efficiency. Simultaneously, the circular hole at the bottom of the protective plate 21 is rotatably connected to the rear end surfaces of the first rotating shaft 7 and the second rotating shaft 10 via bearings. This ensures normal rotation of the shafts and enhances the stability of the protective plate 21, allowing it to better fulfill its function of preventing alfalfa from tangling with the transmission belt.
[0030] refer to Figure 1 The rear box 1 has a support plate fixedly connected to the right side of both the front and back sides, and an electric telescopic rod 22 is fixedly connected to the bottom of the support plate. The output end of the electric telescopic rod 22 is fixedly connected to the top of the steering wheel 3.
[0031] In this embodiment, the support plates on the front and right sides of the rear box 1 and the electric telescopic rod 22 are connected to the steering wheel 3. By extending and retracting the electric telescopic rod 22, the height and angle of the steering wheel 3 can be easily adjusted, thereby achieving flexible control of the device's steering. This allows the device to easily turn in different terrains and working environments, improving the device's adaptability and ease of operation, and further enhancing the efficiency of alfalfa harvesting and baling operations.
[0032] This utility model checks whether the electric wheel 2 and steering wheel 3 can rotate normally, whether the transmission belt is securely installed and has appropriate tension, and whether the cutting saw 5, harvesting roller 8, and actuating conveyor roller 11 can operate normally, and whether any components are damaged or loose; the baling bag is placed on the baling bag opening 16 and secured to the baling bag opening 16 with ropes or cable ties to ensure the baling bag is firmly fixed; according to the terrain and layout of the alfalfa planting area, the operating route of the device is planned; the drive motor 14 is turned on, so that the harvesting roller 8 and actuating conveyor roller 11 begin to rotate. When the electric wheel 2 is started, the device moves to the working area. During the movement, the cutting saw 5 and the harvesting roller 8 cut the alfalfa. The harvesting roller 8 and the spike teeth 13 of the conveying roller 11 work together to grab the cut alfalfa and transport it into the rear box 1. As the alfalfa is continuously transported into the rear box 1, it enters the baling bag through the baling outlet. When the baling bag is full, a new baling bag is replaced to continue the baling operation. After the operation is completed, the closed door 17 on the top of the rear box 1 is opened to clean the inside of the rear box 1 and remove any remaining alfalfa debris and other impurities.
