[0002] In agricultural production, the harvesting of grains is an important link. With the continuous development of agricultural mechanization, the application of grain harvesting platforms is becoming more and more extensive. However, in the existing grain harvesting platform technology, there are still some problems that need to be solved.

[0003] In the traditional grain harvesting process, blowing is usually used to clean weeds and crop roots. However, this method has obvious defects. Since it is impossible to clean larger weeds and crop roots in advance, in order to ensure that the weeds and crop roots are effectively blown away, it is often necessary to set the blowing speed to a higher level. However, too high a blowing speed can easily cause grains to be carried away together, resulting in grain loss and grain leakage. In addition, after the weeds and grains are separated, the existing device has many inconveniences when taking out the separated grains. In most cases, manual scraping operations are required, which not only increases labor intensity and reduces work efficiency, but also easily leads to safety problems.

[0004] Therefore, it is necessary to provide a grain leakage prevention device at the front end of a grain harvesting platform to solve the above technical problems. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a grain leakage prevention device at the front end of a grain harvesting platform provided by the utility model; Figure 2 for Figure 1 The front view schematic cross-sectional view of the upper part of the grain leakage prevention device at the front end of the grain header is shown; Figure 3 for Figure 1 The schematic diagram of the cross-section of the lower part of the grain leakage prevention device at the front end of the grain harvesting platform shown; Figure 4 for Figure 2 The enlarged schematic diagram of part A is shown. A grain leakage prevention device at the front end of a grain harvesting platform comprises: a leakage prevention box 1, a vibration bin 2 is arranged inside the leakage prevention box 1, a rotating shaft 3 is fixedly connected inside the vibration bin 2, a vibration plate 4 is rotatably connected on the surface of the rotating shaft 3, a vibration outlet 5 is opened at the lower right part of the vibration bin 2, a vibration guide plate 6 is fixedly connected to the top of the vibration plate 4, a plurality of guide baffles 7 are fixedly connected to the top of the vibration plate 4, a discharge outlet 8 is opened on the front of the leakage prevention box 1, a discharge guide groove 9 is fixedly connected to the front of the leakage prevention box 1, a separation bin 10 is arranged inside the leakage prevention box 1, a separation port 11 is opened on the front of the separation bin 10, and a feed bin 12 is fixedly connected to the bottom of the leakage prevention box 1. The device can effectively prevent grains from being blown away by mistake by removing larger weeds and crop roots before blowing and cleaning weeds, and correspondingly lowering the blowing speed, thereby minimizing the loss of grain during the harvesting process. This helps to protect the labor results of farmers, improve the final harvest of crops, and increase economic benefits.

[0021] A feeding pipe 13 is fixedly connected to the bottom of the lower silo 12, a feeding motor 14 is installed on the left side of the feeding pipe 13, a swirl rod 15 is fixedly connected to the output end of the feeding motor 14, a swirl disk 16 is fixedly connected to the surface of the swirl rod 15, and a discharge port 17 is opened at the bottom of the feeding pipe 13. The processed grains enter the lower silo 12, and the feeding motor 14 on the feeding pipe 13 is started to drive the swirl disk 16 on the swirl rod 15 to rotate, so that the grains inside the lower silo 12 are delivered, and manual scraping is no longer required, thereby avoiding unnecessary safety risks.

[0022] A vibration motor 18 is installed on the front of the leak-proof box 1, and a crankshaft 19 is fixedly connected to the output end of the vibration motor 18. A crank 20 is rotatably connected to the crankshaft 19, and a vibration shaft 21 is fixedly connected to the bottom of the vibration plate 4. The vibration shaft 21 is rotatably connected to the crank 20. After the vibration motor 18 is started, the crankshaft 19 rotates, and the crank 20 is rotatably connected to the vibration shaft 21, so that the left side of the vibration plate 4 starts to vibrate and the right side rotates on the rotating shaft 3, thereby preliminarily separating the miscellaneous grains to be processed on the vibration plate 4.

[0023] A first feed guide plate 22 is fixedly connected to the inside of the vibration bin 2, and a second feed guide plate 23 is fixedly connected to the inside of the vibration bin 2. A feed port 24 is opened between the first feed guide plate 22 and the second feed guide plate 23. The first feed guide plate 22 and the second feed guide plate 23 guide the miscellaneous grains to be processed into the left side of the vibration plate 4 to facilitate preliminary separation.

[0024] The separation bin 10 is internally installed with a bellows 25, and the bellows 25 is internally installed with a plurality of fans 26. The fans 26 can adjust the air volume, and the coarse grains that have been preliminarily processed can be adjusted to a smaller air volume to avoid the coarse grains being blown away and causing grain leakage.

[0025] A plurality of assembly plates 27 are fixedly connected to the surface of the leak-proof box 1, and assembly holes 28 are opened on the assembly plates 27. The leak-proof device can be installed at the unloading position at the front end of the grain harvesting platform through the cooperation of the assembly plates 27, the assembly holes 28 and the fasteners to avoid the leakage of grains due to excessive air volume.

[0026] The working principle of the grain leakage prevention device at the front end of the grain cutting table provided by the utility model is as follows:

[0027] After the grains are processed by the front end of the grain cutting platform, they will enter the leak-proof box 1 to separate the weeds, crop roots and grains. In this stage, wind power is needed to separate the weeds, crop roots and grains. Because some weeds and crop roots are large, the wind power needed to be used will also be increased, resulting in grains being accidentally blown away and grain leakage. After the grains to be processed enter the vibration plate 4, the vibration plate 4 vibrates, and the grains and smaller weeds will pass through the gap between the guide baffle bars 7 and the vibration outlet 5 for wind screening. At this time, The air volume can be adjusted to a small value to prevent the grains from being blown away. Large weeds and rhizomes will be blocked by the guide baffle 7, and due to vibration, multiple guide baffles 7 are placed diagonally on the vibration plate 4, so that large weeds will be discharged through the discharge port 8. The vibrating guide plate 6 can prevent the grains from being too close to the discharge port 8 of the weeds and prevent them from being rolled out. The device removes larger weeds and crop rhizomes before blowing to clean the weeds, and reduces the blowing speed accordingly, which can effectively prevent the grains from being accidentally blown away and minimize the loss of grain during the harvesting process.

[0028] Compared with the related art, the grain leakage prevention device at the front end of the grain harvesting platform provided by the utility model has the following beneficial effects:

[0029] The equipment can effectively prevent grains from being blown away by mistake by removing larger weeds and crop roots before blowing and lowering the blowing speed accordingly, thus minimizing the loss of grain during the harvesting process. This helps to protect the labor results of farmers, improve the final harvest of crops, and increase economic benefits; at the same time, the spiral feeding mechanism can promptly and smoothly bring the separated grains out of the device, avoiding the heavy work of manual material removal. Operators do not need to bend over for a long time, which reduces physical fatigue and injury and avoids unnecessary safety risks.
