DETAILED DESCRIPTION
[0026] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes that can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole of the utility model or regarded as the limitation or restriction of the technical scheme of the utility model.
[0027] EMBODIMENT
[0028] As shown in Figure 1 , an agricultural harvesting equipment is composed of a harvester 1 and an annular cylinder 2 installed on the discharge pipe 11 of the harvester 1. The annular cylinder 2 is a key component, and the internal structure of each component cooperates to realize the functions of efficient discharging, dust removal and impurity separation.
[0029] As shown in Figure 2 , the rotating shaft 3 is rotatably installed in the annular cylinder 2, and the blade 31 of helical structure is installed on the upper end of the rotating shaft 3. The blade 31 is arranged in the connecting port 21 connecting the discharge pipe 11 and the annular cylinder 2, and is located at the axis of the connecting port 21. When the grain flows out from the discharge pipe 11, the high-speed flowing grain impacts the blade 31. Since the blade 31 is of helical structure, it can be more effectively driven by the grain flow, so that the rotating shaft 3 starts to rotate.
[0030] As shown in Figure 4 , the guide table 33 of circular truncated cone shape is installed at the lower end of the rotating shaft 3, and a plurality of guide tables 33 are uniformly distributed. The guide table 33 rotates with the rotating shaft 3, and the circular truncated cone structure can uniformly guide the grain to the surrounding, avoiding the concentration of the grain in one place to cause uneven discharging or scattering.
[0031] The scraper 34 is arranged at the lower part of the guide table 33, and the lower part thereof is in contact with the filter screen 41. When the guide table 33 rotates, the scraper 34 rotates with it, which can clean the impurities attached to the filter screen 41 in time, prevent the filter screen 41 from being blocked, and ensure the persistence of the filtering and separating effect.
[0032] As shown in Figure 3As shown, the annular cylinder 2 is internally provided with an annular filter cylinder 4, which forms a closed collection space 42 with the inner wall of the annular cylinder 2, and the inside of the filter cylinder 4 is a material falling space 43, both of which are communicated through a filter screen 41. The end of the material guide table 33 is located above the filter screen 41, which is in the shape of an inverted circular table. When the grains are guided by the material guide table 33 and fall down, they will pass through the filter screen 41. In this process, the straw debris, dust and other impurities in the grains are intercepted by the filter screen 41 and fall into the collection space 42, while the pure grains pass through the filter screen 41 and enter the material falling space 43, realizing effective separation of impurities and grains.
[0033] The connecting port 21 at the upper part of the annular cylinder 2 is fixedly connected with the discharge pipe 11, ensuring the stability of the structure. The annular rotating seat 22 installed in the annular cylinder 2 is provided with support rods 23 for fixation on the side surface, the support rods 23 are arranged in an annular array, and the upper part is provided with an arc-shaped chamfer structure, which not only ensures the stability of the rotating seat 22, but also reduces the obstruction to the flow of grains. The annular clamping seat 32 on the rotating shaft 3 is clamped in the annular groove of the rotating seat 22, so that the rotating shaft 3 can stably rotate in the annular cylinder 2, and installation and maintenance are facilitated.
[0034] As shown in the drawings, Figure 5 The cavity wall at the lower part of the filter screen 41 in the material falling space 43 is provided with a circular table-shaped flow guide surface, which helps to guide the grains to fall smoothly and prevent the grains from accumulating in the material falling space 43. At the same time, the material falling space 43 is provided with a plurality of concave annular spaces corresponding to the material guide table 33, further ensuring the stability and uniformity of the grains during falling.
[0035] The technical scope of the present application is not limited to the content described in the above description, and those skilled in the art can make various modifications and modifications to the above embodiments without departing from the technical idea of the present application, and these modifications and modifications should be within the protection scope of the present application.
