The first circular plate 310 is in transmission connection with the output shaft of the motor 200, the transmission connection of the first circular plate and the output shaft can be realized through key connection, and in this case, a connecting hole and a key slot need to be formed in the first circular plate 310; the connection can also be realized through shaft sleeve connection, in this case, a connecting shaft needs to be arranged on the first circular plate 310, and the connecting shaft is connected with the output shaft of the motor 200 through a shaft sleeve and a pin. The specific connection mode of the two is not limited herein. Of course, the second circular plate 320 generally needs to rotate through the connecting shaft and the bearing seat.

The first circular plate 310 and the second circular plate 320 are connected by a plurality of connection plates 330, so that the first circular plate 310 and the second circular plate 320 are integrally connected. The plurality of connection plates 330 are uniformly distributed along the circumferential direction of the first circular plate 310 and are perpendicular to the first circular plate 310.

A sieve plate 400 is detachably connected between two adjacent connecting plates 330, and the sieve plate 400 is provided with a plurality of sieve holes 410. The materials rotate along with the motor 200 in the roller frame 300 and the sieve plate 400, and under the action of centrifugal force, impurities with the size smaller than that of the sieve holes 410 can fly out of the sieve holes 410, so that the purpose of sieving is achieved.

Of course, the drum rack 300 or the sieve plate 400 should be provided with a material inlet, a material outlet, a material storage bin, etc. to facilitate the feeding of the material and the taking out of the sieved material, which will not be described in detail herein.

Meanwhile, the sieve plate 400 is detachably connected between the connecting plates 330, so that when the sieve holes 410 need to be cleaned, the sieve plate 400 only needs to be detached for cleaning, the whole roller frame 300 does not need to be detached, and the operation is convenient.

Figure 3 is a perspective view of a screen panel used with a drum screen machine according to one embodiment of the present application. Figure 4 is a perspective view of a roller frame and screen panel used in a roller screen machine according to an embodiment of the present application with one screen panel open.

In some embodiments, as shown in fig. 2, a rotation shaft 340 is connected between the first circular plate 310 and the second circular plate 320, and the rotation shaft 340 is perpendicular to the first circular plate 310 and is disposed near one of the connection plates 330. As shown in fig. 3 and 4, a ring sleeve 420 is disposed on a side of the screen plate 400 close to the rotating shaft 340, and the ring sleeve 420 is rotatably connected to the rotating shaft 340, so that the screen plate 400 is rotatably connected to the rotating shaft 340. One side of the screen plate 400, which is far away from the rotating shaft 340 along the circumferential direction of the first circular plate 310, is provided with a fixing ear plate 430, and the fixing ear plate 430 is fixed on another connecting plate 330 through a bolt, so that the screen plate 400 and the connecting plate 330 are relatively fixed. Under the structure, the sieve plate 400 can rotate relative to the rotating shaft 340, so when the sieve holes 410 need to be cleaned, only the bolts on the fixed lug plates 430 need to be disassembled, and then the sieve plate 400 is rotated to be opened, and the operation is convenient. After cleaning, the screen 400 is turned to close and the bolts on the fixing lugs 430 are fixed.

In order to increase the fastening degree of the connection, in some embodiments, as shown in fig. 3, the annular sleeves 420 and the fixing ear plates 430 are provided in plural numbers and are spaced apart from each other along the length direction of the screening deck 400, so that the relative fixing is realized from plural positions, the fixing is more firm, and the normal operation of the screening work is ensured.

In the actual installation process, there are gaps between the screen plate 400 and the connection plate 330, the first circular plate 310 and the second circular plate 320 to facilitate the installation and rotation of the screen plate 400, but it should be ensured that material cannot escape through the gaps. Therefore, in some embodiments, the gaps between the screen plate 400 and the connection plate 330, the first circular plate 310, and the second circular plate 320 are smaller than the diameter of the sieve holes 410, and impurities can fly out of the sieve holes 410, but materials cannot fly out. When the gap is smaller than the diameter of the sieve holes 410, the material does not leak out of the gap.

In some embodiments, the number of connector plates 330 and screen panels 400 are both N, which is a positive integer greater than or equal to 2.

Fig. 5 is an axial cross-sectional view of fig. 4. As shown in fig. 5, the connecting plates 330 and the screening deck 400 are both arc-shaped plates, and the sum of the angles of the adjacent connecting plates 330 and the screening deck 400 is 360 °/N, where the angle refers to the central angle of the arc-shaped plates. I.e. the sum of alpha and beta in fig. 5 is 360/N. Generally, N can be 2, 3 or 4, and when the value of N is larger, the structure becomes complicated, which increases the difficulty of manufacturing.

The connection plate 330 serves to connect the first circular plate 310 and the second circular plate 320 and support the screen plate 400, and may ensure the basic structural strength of the roller frame 300. The angle of the connection plate 330 is not necessarily large, and in some embodiments, the angle a of the connection plate 330 is 5 ° to 10 °, which also allows the angle β of the screening deck 400 to be large, increasing the area of the screening deck 400 and increasing the screening efficiency.

In some embodiments, as shown in fig. 5, the connection plate 330 is located at the edge of the first circular plate 310, so that the space enclosed by the roller frame 300 and the screen deck 400 is maximized, and more materials can be accommodated, thereby improving the screening efficiency.

During screening, material and impurities are constantly impacting the screen deck 400, and in order to prevent deformation of the screen deck 400, in some embodiments, the screen deck 400 has a thickness of at least 3 mm. The screen plate 400 with the thickness can bear impact without deformation, and the normal use of the screen plate 400 is ensured.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
