Description

一种抖动筛及筛选***A shaking screen and screening system 技术领域technical field
本申请涉及农业机械技术领域，具体涉及一种抖动筛及筛选***。The application relates to the technical field of agricultural machinery, in particular to a shaking screen and a screening system.
背景技术Background technique
在收割机筛选***中，振动筛的前端设置用于抖松和分离秸秆的波纹板，波纹板朝向中间段的鱼鳞筛倾斜设置，以便将秸秆导引至鱼鳞筛上进行进一步筛选分离。In the harvester screening system, the front end of the vibrating screen is provided with a corrugated plate for fluffing and separating straw, and the corrugated plate is inclined toward the fish scale screen in the middle section, so as to guide the straw to the fish scale screen for further screening and separation.
现有的波纹板为整块平板上凸起多排波纹状分布的筛板结构，收割过程中，秸秆持续通过等高的波纹状筛板，波纹落差小，无法将秸秆抖散，造成秸秆聚团，容易夹带籽粒，抖松和分离效果不理想。The existing corrugated plate is a sieve plate structure with multiple rows of corrugated distribution on the whole plate. During the harvesting process, the straw continues to pass through the corrugated sieve plate of the same height, and the drop of the corrugation is small, so the straw cannot be shaken, causing the straw to gather. It is easy to entrain the grain, and the fluffing and separation effect is not ideal.
为解决这一技术问题，现有技术中，将整块的波纹板设置呈台阶式，通过多段台阶，整体上形成具有一定高度的落差，使秸秆充分抖散抖松，避免聚团。但该结构的落差设置造成波纹板在竖向上占用的空间大，致使收割机整体的竖向高度增加，影响收割机的机动性和稳定性。同时，台阶式结构是逐渐降低的结构，整体落差大，但局部落差仍较小，因此，秸秆量大时，容易沿台阶面直接聚团滑落，而无法实现抖松的效果。In order to solve this technical problem, in the prior art, the whole corrugated board is arranged in a stepped type, and through multiple steps, a drop with a certain height is formed as a whole, so that the straw can be fully shaken and loosened, so as to avoid agglomeration. However, the setting of the drop of the structure causes the corrugated board to occupy a large space in the vertical direction, which increases the vertical height of the harvester as a whole and affects the maneuverability and stability of the harvester. At the same time, the stepped structure is a gradually decreasing structure, and the overall drop is large, but the local drop is still small. Therefore, when the amount of straw is large, it is easy to aggregate and slide down along the step surface, and the effect of shaking and loosening cannot be achieved.

实施例1Example 1
本实施例提供一种抖动筛，如图1所示，包括安装件和多个筛齿2d，本实施例中，安装件为板状结构，即安装板1d。安装板1d具有装配面12d以及背向装配面12d一侧且与装配面12d呈锐角设置的安装面11d，本实施例中，如图2所示，安装板1d中间折弯形成具有一定倾角的坡面，该坡面形成供筛齿2d固定的安装面11d，安装板1d的下底面形成装配面12d，即如图4所示，抖动筛整体装配至波纹板6d的末端时，装配面12d与波纹板6d面面贴合固定。筛齿2d沿装配面12d与安装面11d之间形成的夹角的开口方向延伸，且一端为固定端，间隔固定在安装面11d上，另一端为自由 端，呈悬空设置，当振动筛整体往复振动时，作物从波纹板6d滑落到抖动筛上，并受悬空的筛齿2d抖动扬起，然后下落至鱼鳞筛7d上，实现将作物抖散抖松。另外，抖动筛可以根据不同需要按照不同的倾斜角度设置在波纹板6d上，充分利用空间，使筛选***在保证筛选效果的同时结构更紧凑。This embodiment provides a shaking screen, as shown in FIG. 1 , which includes a mounting member and a plurality of screen teeth 2d. In this embodiment, the mounting member is a plate-like structure, that is, a mounting plate 1d. The mounting plate 1d has a mounting surface 12d and a mounting surface 11d that faces away from the mounting surface 12d and forms an acute angle with the mounting surface 12d. In this embodiment, as shown in FIG. The slope surface forms the mounting surface 11d for fixing the screen teeth 2d, and the lower bottom surface of the mounting plate 1d forms the mounting surface 12d, that is, as shown in FIG. It is fixed with the corrugated board 6d surface-to-surface. The screen teeth 2d extend along the opening direction of the angle formed between the mounting surface 12d and the mounting surface 11d, and one end is a fixed end, which is fixed on the mounting surface 11d at intervals, and the other end is a free end, which is suspended in the air. During the reciprocating vibration, the crops slide from the corrugated plate 6d to the shaking screen, are shaken and raised by the suspended screen teeth 2d, and then fall to the fish scale screen 7d to realize the shaking and loosening of the crops. In addition, the shaking screen can be arranged on the corrugated plate 6d according to different inclination angles according to different needs, making full use of the space and making the screening system more compact while ensuring the screening effect.
如图3所示，本实施例中，筛齿2d为圆柱状结构，当然也可以为片状结构，视具体情况而定。任一筛齿2d呈阶梯状折弯设置，适于引导作物沿筛齿2d由位于安装面11d的固定端向自由端行进。两个筛齿2d的固定端固定连接，形成匚形的筛叉单元3d，两个筛叉单元3d叠加设置，其一所叉单元的匚形的竖直部搭接固定在另一筛叉单元3d的其一筛齿2d上，形成筛叉组4d，多个所述筛叉组4d均匀间隔设置在安装面11d上。如图1所示，所有筛叉组4d通过压板5d压合并焊接固定在安装板1d的安装面11d上。每个筛齿2d悬空的长度较长，一方面可以提升作物下落至鱼鳞筛7d的高度，另一方面可以提高筛齿2d的弹性，使其随振动筛运动时，抖动效果更明显。As shown in FIG. 3 , in this embodiment, the screen teeth 2d have a cylindrical structure, but of course they can also be a sheet structure, depending on the specific situation. Any of the screen teeth 2d is bent and arranged in a stepped shape, and is suitable for guiding crops to travel along the screen teeth 2d from the fixed end located on the installation surface 11d to the free end. The fixed ends of the two screen teeth 2d are fixedly connected to form an indented screen fork unit 3d. The two screen fork units 3d are superimposed and arranged, and the indented vertical part of one fork unit is overlapped and fixed to the other screen fork unit. On one of the screen teeth 2d of 3d, a screen fork group 4d is formed, and a plurality of the screen fork groups 4d are evenly spaced on the installation surface 11d. As shown in FIG. 1 , all the screen fork groups 4d are fixed on the mounting surface 11d of the mounting plate 1d by pressing and welding through the pressing plate 5d. The suspended length of each sieve tooth 2d is long, on the one hand, it can increase the height of crops falling to the fish scale screen 7d, on the other hand, it can improve the elasticity of the sieve tooth 2d, so that when it moves with the vibrating screen, the shaking effect is more obvious.
本实施例中，安装板1d、筛齿2d和压板5d均采用铝合金材质制成，以减轻整个筛选***的重量，从而减少振动惯性。In this embodiment, the mounting plate 1d, the screen teeth 2d and the pressing plate 5d are all made of aluminum alloy material, so as to reduce the weight of the entire screening system, thereby reducing the vibration inertia.

The crops fall on the fish scale screen 7d from the corrugated plate 6d through the shaking screen, and are screened and transported backward through the fish scale screen 7d. The corrugated plate 6d is inclined downward toward the fish scale screen 7d, and the inclination angle with the horizontal plane is 3 degrees, and the shaking screen is inclined upward. It is extended and the included angle with the corrugated plate 6d is an obtuse angle. At the same time, the included angle with the fish scale screen 7d is an acute angle. In order to ensure the vertical height between the free end of the screen teeth 2d and the fish scale screen 7d, the crops can be fully shaken and loosened.
