Description

Technical Field

[0001] This invention relates to the field of grain processing technology, and in particular to a round roller primary cleaning screen. Background Technology

[0002] Before the rice is hulled, it needs to be preliminarily sieved and filtered to remove the straw mixed in with the rice. Traditional sieving is mostly done manually using sieves, which is time-consuming, labor-intensive, and inefficient. In addition, the straw attached to the sieves needs to be cleaned after sieving, which is quite troublesome. Utility Model Content

[0014] Furthermore, it also includes:

[0015] An extension plate is slidably installed inside the machine body. One side of the extension plate is in contact with the guide slope, and the other side extends to one side of the roller in the X direction. The lower end face of the extension plate is spaced from the radial outer side of the roller.

[0016] Furthermore, it also includes:

[0017] The inner plate is installed on one side wall of the machine body, and is located below and adjacent to the extension plate;

[0018] Furthermore, a guide channel is also provided on the outer side of the discharge port.

[0019] Furthermore, a rice outlet hopper is provided at the lower end of the machine body to discharge the rice that has passed through the roller.

[0020] Furthermore, a dust extraction port is provided on the side of the machine body away from the slag discharge port. The horizontal height of the dust extraction port is lower than the horizontal height of the lower edge of the drum. A second guide plate is provided between the dust extraction port and the drum, and the second guide plate is connected and fixed to one side wall of the machine body.

[0021] Furthermore, the organism also includes:

[0022] The drive motor is mounted on one side of the machine body.

[0023] The roller shaft has the roller fixedly mounted on it, and one end of the roller shaft passes through the machine body and is connected to the drive motor via belt drive.

[0025] The baffle has support plates on both sides that are sleeved on the roller shaft and rotatably connected to the roller shaft, and a counterweight assembly is provided between the lower edges of the two support plates.

[0026] The beneficial effects of this utility model are as follows:

[0027] The rice entering the machine flows along the guide slope to the right side of the drum. The rice then passes through the sieve holes and is discharged through the rice outlet hopper. The straw mixed in with the rice is blocked on the outside of the drum. As the drum rotates, the straw is gradually carried to the position of the drum near the slag discharge port. It falls onto the slag discharge plate by gravity and is then discharged from the slag discharge port along the slag discharge plate. This effectively removes the straw mixed in with the rice.

Then, the rice passes through the screen holes and is discharged through the rice outlet hopper. The straw mixed in the rice is blocked on the outside of the drum. As the drum rotates, the straw is gradually carried to the position of the drum near the slag discharge port. It falls onto the slag discharge plate by gravity and is then discharged from the slag discharge port along the slag discharge plate. This can effectively remove the straw mixed in the rice.

[0068] This embodiment provides a rotary pre-cleaning screen, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] Furthermore, a dust extraction port is provided on the side of the machine body 300 away from the slag discharge port 306. The horizontal height of the dust extraction port is lower than the horizontal height of the lower edge of the drum 303. A guide plate 2 is provided between the dust extraction port and the drum 303. The guide plate 2 is connected and fixed to one side wall of the machine body 300.

[0070] By adopting the above technical solution, the dust generated during screening can be extracted through the dust extraction port, and the second guide plate plays a role in blocking and guiding the flow, preventing the rice from being extracted by the dust extraction port.

[0071] Example 8:

[0072] This embodiment provides a rotary pre-cleaning screen, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0073] Furthermore, the machine body 300 also includes:

[0074] The drive motor is installed on one side of the machine body 300mm away.

[0075] The roller shaft 307 and the roller 303 are fixedly installed on the roller shaft 307. One end of the roller shaft 307 passes through the machine body 300 and is connected to the drive motor via belt drive.

[0076] Baffle 308 is disposed between the roller shaft 307 and the extension plate 304, and is located inside the roller 303;

[0077] Among them, the baffle 308 has support plates on both sides that are sleeved on the roller shaft 307 and rotatably connected to the roller shaft 307, and a counterweight assembly is provided between the lower edges of the two support plates.

[0078] In the above technical solution, a V-shaped connecting plate is set between the lower edges of the two support plates, and a counterweight component is fixedly installed on the upper end of the V-shaped connecting plate. The counterweight component is a counterweight block with a certain mass, so that the baffle will not swing due to the rotation of the roller shaft and the impact of the rice.

[0079] By adopting the above technical solution, one side of the baffle is set towards the feeding area formed between the inner plate and the extension plate to form a blocking surface, so that the rice will not splash towards the discharge port after passing through the roller.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
