Description

Technical Field

[0001] The utility model relates to the technical field of agricultural harvesting, in particular to a grain splash prevention device at the rear end of a grain harvesting platform. Background Art

[0002] In the field of agricultural harvesting, the harvesting of grains is an important link. During the harvesting operation of grains, grain splashing often occurs at the rear end of the grain cutting platform, which not only causes grain loss, but also affects the harvesting efficiency and quality. Therefore, a grain splash prevention device at the rear end of the grain cutting platform is needed to avoid grain splashing. However, the existing grain splash prevention device at the rear end of the grain cutting platform has certain defects.

[0003] The blocking area of ​​the traditional grain-prevention blocking device at the rear end of the grain harvesting platform is usually fixed. This means that when faced with different operating environments and crop yields, the blocking area cannot be flexibly adjusted to meet actual needs. For example, when the crop yield is large or the harvesting speed is fast, the grains are easily splashed out due to insufficient blocking area, causing unnecessary losses; moreover, most of the existing blocking devices rely on threaded holes for installation. This installation method has certain limitations. First, the position and number of the threaded holes are fixed. If the installation position does not match, it may cause installation difficulties or even impossible to install. Secondly, the threaded holes are prone to wear after long-term use, which affects the stability and firmness of the installation.

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

When the crop yield is high or the harvesting speed is fast, it can effectively prevent a large amount of grains from splashing and reduce food losses. When a larger blocking area is not needed, the extension plate can be folded up, which not only saves space, but also facilitates the transportation and storage of the equipment.

[0021] The bottom of the blocking bin 1 is fixedly connected with an assembly ring 17, and a plurality of fixed clamps 18 are fixedly connected to the assembly ring 17. A clamping threaded rod 19 is threadedly connected to the fixed clamp 18. A movable clamp 20 is rotatably connected to the bottom of the clamping threaded rod 19, and a clamping pad 21 is fixedly connected to the movable clamp 20. A rotating rod 22 is fixedly connected to the top of the clamping threaded rod 19. When the blocking bin 1 is fixed, the blocking bin 1 is initially placed at the rear end of the grain cutting platform. By rotating the rotating rod 22, the clamping threaded rod 19 can be driven to rotate, and then the movable clamp 20 is driven to move upward through the threaded connection with the fixed clamp 18 to clamp the edge of the rear end. By rotating multiple rotating rods 22, it can be firmly fixed to the rear end of the grain cutting platform. While ensuring stability, it is not restricted by the model of the threaded hole.

[0022] A buffer plate 23 is fixedly connected inside the blocking bin 1, and a guide slope 24 is arranged on the buffer plate 23. When the grains of miscellaneous cereals splash, the grains will first touch the buffer plate 23. The buffer plate 23 is arc-shaped, and the miscellaneous cereals will be guided to the arc-shaped baffle plate 25. However, since the grains first touch the buffer plate 23, the degree of splashing will be greatly reduced when they touch the arc-shaped baffle plate 25 again, so as to avoid splashing again due to excessive splashing force.

[0023] The blocking bin 1 is fixedly connected with an arc-shaped baffle plate 25 , and an observation window 26 is provided on the arc-shaped baffle plate 25 . The observation window 26 allows operators to observe the flow of seeds and the working state inside the device, and to find problems in time and make adjustments or maintenance.

[0024] The limit spring 15 is a tension spring, the observation window 26 is made of tempered glass, and the clamping pad 21 is made of rubber, which can increase the friction of the clamping pad 21 and make it clamp more firmly. The tempered glass can ensure the light transmittance of the observation window 26 while ensuring its sufficient strength.

[0025] The pull rod 16 is sleeved with an anti-skid sleeve 27 , and the pull rod 16 is fixedly connected with an anti-slip disk 28 . The anti-skid sleeve 27 and the anti-slip disk 28 can prevent the pull rod 16 from slipping out of the hand when the pull rod 16 is pulled.

[0026] The working principle of the grain splash prevention device at the rear end of the grain harvesting table provided by the utility model is as follows:

[0027] When dealing with the situation of grain splashing at the rear end of the grain harvesting platform, the device may need to have a larger blocking area due to actual needs, such as when the harvesting speed is fast and the unit yield is high. The flip plate 3 and the folding plate 8 of the device are in a retracted state when not needed. When the harvesting speed is fast, the telescopic button 4 can be pressed. A spring is provided inside the telescopic button 4, which can be retracted into the outer wall of the blocking chamber 1 by pressing. At this time, the flip plate 3 is unrestricted and can be flipped, such as Figure 2 At this time, the telescopic button 4 on the top is reset and then extends into another limiting hole 5 to make it stable. The two flip plates 3 can increase the blocking area on the side of the blocking bin 1, and the folding plate 8 hinged on the top can also be flipped. At this time, the pull rod 16 is pulled so that the plug-in short rod 11 no longer restricts the mobile plug-in plate 12, so that it can be flipped. After the flipping is completed, the pull rod 16 is released. Due to the elastic force of the limit spring 15, the connecting plate 10 begins to reset, and the plug-in long rod 13 is plugged into the mobile plug-in plate 12 to limit and fix it. The folding plate 8 can increase the blocking area at the top of the blocking bin 1, so that the device can flexibly unfold the extended baffle according to actual needs to increase the blocking area. This feature greatly improves the adaptability of the device.

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

[0029] The device can flexibly unfold the extended baffle to increase the blocking area according to actual needs. This feature greatly improves the adaptability of the device. When the crop yield is high or the harvesting speed is fast, it can effectively prevent a large amount of grain from splashing and reduce grain loss. When a larger blocking area is not needed, the extended plate can be folded up, which not only saves space but also facilitates the transportation and storage of the equipment. The blocking device abandons the limitation of threaded hole installation and adopts a direct clamping installation method, which greatly simplifies the installation process and saves installation time and labor costs. In the past, installation through threaded holes required tedious steps such as precise alignment and tightening screws, and was prone to problems such as screw stripping and threaded hole damage. Direct clamping installation does not require complicated tools and operating skills. Even inexperienced operators can complete the installation quickly, which improves work efficiency. Especially during the busy farming season, it can be put into use faster to harvest grain.
