Description

Technical Field

[0001] The invention relates to the technical field of feeder clamps, and in particular to a cutting and throwing device for a peanut seedling harvester. Background Art

[0002] According to the latest FAO statistics, in 2018, my country's peanut harvesting area was 4.62 million hm2, and the output was 17.33 million tons, ranking second and first in the world respectively, accounting for 16.2% and 37.7% of the world. Generally, the yield of peanut seedlings per mu is equivalent to the yield of peanut pods, that is, my country's annual peanut seedling output is 17.33 million tons. If converted into fresh seedlings, the annual output is about 34 million tons. Data show that the crude protein content in peanut seedlings exceeds 12%, the crude fat content reaches 2%, and the carbohydrate content exceeds 45%. Compared with other common forage grasses, its crude protein content is about 1.5 times that of Sudan grass, slightly higher than perennial ryegrass, and basically equivalent to the crude protein content of alfalfa during flowering. It is an excellent livestock and poultry feed. In the main production areas, the price of peanut seedlings per 667m2 can reach 50 to 150 yuan. The development and utilization of peanut seedlings as livestock and poultry feed can not only alleviate the contradiction between people and animals competing for food in my country, but also improve the benefits of the peanut industry and farmers' income.

The plastic film cannot be digested by livestock and poultry and will accumulate in the stomach, causing indigestion or even death of livestock and poultry, which greatly affects the quality of the harvested peanut seedlings. There are a lot of impurities in the peanut seedlings and they cannot be used as livestock and poultry feed. The harvested peanut seedlings seriously affect the feed quality.

[0018] 1. The present invention harvests peanut seedlings through the harvester body. At this time, the peanut seedlings after harvesting enter the interior of the receiving frame along the drop plate. At this time, the peanut seedlings enter the interior of the first screening plate along the material discharge trough opened on the surface of the receiving frame. The first screening plate and the second screening plate can prevent the peanut seedlings that fall into the first screening plate from falling through the anti-falling plate to prevent the peanut seedlings from falling during the screening process. Then, the connecting rod on the first mounting plate is rotated. At this time, the connecting rod drives the eccentric rod to rotate. The eccentric rod and the connecting rod are not at the same center of a circle. At this time, the eccentric rod pulls the second mounting plate to move through the pull rod. When the second screening plate drives the second mounting plate to push the limiting plate during the vibration process, the limiting plate drives the first screening plate to vibrate, so that the first screening plate and the second screening plate are shaken at the same time. The screening holes of the first screening plate and the second screening plate are different, so that different impurities can be screened, thereby screening the impurities on the first screening plate, and preventing the impurities from being mixed inside the harvested peanut seedlings, which affects the quality of the feed.

[0019] 2. The present invention starts the servo motor, and the output end of the servo motor drives the worm wheel to rotate. Since the worm wheel is meshed with the worm, the worm wheel drives the worm to rotate during the rotation process, and the worm drives the connecting rod to rotate, so that no manual operation is required by human personnel, and automatic processing is realized, which further improves the operation effect of the device. When the connecting plate is deformed, since the connecting plate is a component of an elastic structure, the first screening plate and the second screening plate can be reciprocated and vibrated, and the connectivity between the first screening plate and the second screening plate can be improved;

[0020] 3. When the present invention performs the first screening, the peanut vines are on the switching plate on the first screening plate. At this time, the hydraulic rod is started, and the telescopic end of the hydraulic rod drives the pull plate to open through the push plate. During the opening process, the pull plate drives the slide bar to slide in the slide groove provided on the surface of the second screening plate. The slide bar can stabilize the position of the pull plate when it moves to avoid position deviation of the pull plate during the sliding process. At this time, the discharge trough provided on the surface of the second screening plate is opened, and the first screening plate performs vibration screening. Impurities mixed in the peanut vines fall along the screening holes provided on the surface of the switching plate. At this time, the drive motor is started, and the output end of the drive motor drives the toggle plate The toggle plate 2 rotates, and the push ball rotates during the rotation, so that the toggle plate 1 rotates. The toggle plate 1 drives the movable rod to rotate when it rotates. At this time, the movable rod drives the switching plate to rotate at an angle through the connecting block, and the torsion spring can drive the movable rod to reset, thereby further improving the use effect of the device. The pull plate closes the discharge chute opened on the surface of the second screening plate. At this time, the peanut seedlings on the switching plate slide down, so that the peanut seedlings slide onto the surface of the pull plate. At this time, the second screening plate drives the pull plate to perform a second vibration screening process on the peanut seedlings during the vibration process, thereby enabling double screening of the peanut seedlings.
