[0002] With the advancement of agricultural modernization, agricultural production has increasingly higher requirements for mechanization and automation. Efficient, convenient rice harvesting devices that are adaptable to different terrains and planting scales are essential for improving agricultural production efficiency, reducing labor intensity, and promoting sustainable agricultural development.

[0003] In the process of processing paddy into rice, if the paddy is not separated from the stalk, the stalk will affect the normal operation of subsequent processing equipment, leading to reduced processing efficiency and even damage to the equipment. Separating the two makes the subsequent cleaning, hulling, and milling processes smoother, improving the processing quality and precision of the rice. In existing technologies, the harvested rice plants are held and forcefully slammed against wooden frames or stone troughs to break off the paddy through impact. However, this separation method requires a lot of manual labor and each person can only process a small amount of rice per day, which cannot meet the needs of large-scale production. Furthermore, uneven force can cause the husk of the paddy to crack, affecting the quality and storage stability of the rice. Summary of the Invention

[0015] This utility model has the following beneficial effects: 1. In this utility model, when the rice harvester is started, the moving mechanism drives the equipment to move. Then, the first driving component is started, which drives the rotating shaft to rotate, thereby causing the waterproof shell and rotating ring to rotate. The fixed column and scraper between adjacent rotating rings rotate accordingly. When the scraper rotates, it hooks the rice, scrapes off the rice grains and ears, and gently grabs them. Through inertia, it transfers them to the preset collection box. The remaining rice stalks contact the bottom cutting blade. At this time, the second driving component is started, and the cutting blade drives the gear to rotate. The gear drives the transmission belt and the cutting blade to drive. The cutting blade cuts the rice stalks in a cutting state, causing them to fall into the inclined plate, thus separating the rice grains from the rice stalks, reducing manual intervention, and improving the practicality and functionality of the equipment.

[0016] 2. In this utility model, when the sunlight is too strong, the telescopic rod is activated, and its push rod slider slides up the inner wall of the groove. The rotating rod rotates accordingly, with one end rotating around rotating ball one and the other end rotating around rotating ball two. During the rotation, the sunshade is pushed out from the fixed block, extending the sunshade length, thus providing sunshade for the users, reducing sun exposure, optimizing the working environment for the staff, and thereby improving harvesting efficiency.

[0025] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The scraping component 205 includes multiple fixed posts 2051, the front ends of which are fixedly connected to the rear side of the rotating ring 2042.

[0027] Working principle: When the rice harvester 1 is started, the moving mechanism 4 will drive the equipment to move to the right. Then, the first driving component 2032 will be activated, which will drive the rotating shaft 2033 to rotate. The rotating shaft 2033 will further drive the waterproof shell 2031 and the rotating ring 2042 to rotate. The fixed column 2051 and the scraper 2052 adjacent to the rotating ring 2042 will also rotate. During the rotation, the scraper 2052 will hook the rice and scrape off the top of the rice along with the ears of rice. The scraper 2052 will lightly grasp the rice and then, due to inertia, remove it. The function is to transfer the rice grains and ears of rice together into the pre-designed collection box 201, while the remaining rice stalks will come into contact with the cutting blade 2074 at the bottom. At this time, the second drive component 2071 is activated, and the cutting blade 2074 will drive the gear 2072 to rotate. The gear 2072 will then drive the transmission belt 2073 and the cutting blade 2074 to move together, so that the cutting blade 2074 will be in a cutting state, which can cut the rice stalks and drop them into the interior of the inclined plate 2062, thus realizing the separation of rice grains and rice stalks, reducing manual intervention, and thus improving the practicality and functionality of the equipment. When the sunlight is too strong, the telescopic rod 304 is activated. The telescopic rod 304 pushes the slider 3051, causing the slider 3051 to slide upward along the inner wall of the groove 303. The rotating rod 3053 will also rotate accordingly. One end of the rotating rod 3053 will rotate around the first rotating ball 3052, and the other end will rotate around the second rotating ball 3054. During the rotation, the rotating rod 3053 will push the sunshade 302 out of the fixed block 301, thereby extending the length of the sunshade. This provides sun protection for the user, reduces sun exposure, and optimizes the working environment for the staff.

[0028] Understandably, in order to control the harvesting device, the device also includes a control system, which includes a controller, a setting unit, etc. The controller can control the opening or closing of electrical components such as the first drive component and the second drive component.
