Furthermore, the material unloading component includes a material mixing box 2 connecting the storage box 201 and the screening box 1. A rotating rod driven by a motor is arranged inside the material mixing box 2. Several groups of material mixing leaves 202 are evenly distributed around the side wall of the rotating rod. Several groups of material mixing leaves 202 are adapted to the material mixing box 2 to facilitate uniform speed unloading.

Furthermore, at least two groups of screening buckets 502 are provided, and the filter holes of each group of screening buckets 502 gradually decrease from top to bottom; impurities larger than rapeseed can be screened out through several groups of screening buckets 502 above the side wall of the rotating shaft 5, and the rapeseed can be filtered and intercepted through a group of screening buckets 502 at the bottom end of the side wall of the rotating shaft 5, and impurities smaller than rapeseed can pass through a group of screening buckets 502 at the bottom end and fall into the impurity receiving bucket 501 for collection.

Furthermore, the screening component also includes a rotating shaft 5 driven to rotate by a motor, the rotating shaft 5 is rotatably connected to the screening bucket 502 and the impurity receiving bucket 501, and a plurality of groups of material shifting brushes 503 are connected to the side wall of the rotating shaft 5, and the bristles on the material shifting brush 503 are in contact with the screening bucket 502 and the impurity receiving bucket 501; the motor drives the rotating shaft 5 to rotate and drives the material shifting brush 503 to rotate, and the material shifting brush 503 can shift the impurities or rapeseed on the impurity receiving bucket 501 and the screening bucket 502, which can not only accelerate the filtering of the raw materials, but also avoid the mesh of the screening bucket 502 from being blocked, thereby improving the screening efficiency.

As shown in Figures 1, 2 and 4, one side wall of the screening box 1 is connected to a debris removal box 3, and the lower part of the debris removal box 3 is connected to a debris collection box 303. A fan 301 is provided on the debris removal box 3, and a filter screen 302 is provided inside the debris removal box 3. An air inlet 101 is installed on the other side wall of the screening box 1, and a dustproof net is provided on the air inlet 101 to prevent external interference from entering the screening box 1. A debris discharge port is provided at the connection between the side wall of the screening box 1 and the debris collection box 303, and a dust discharge port is provided. The impurity outlet is matched with several groups of screening buckets 502 and impurity receiving buckets 501 located at the upper part of the screening box 1, so as to facilitate the discharge of impurities. A baffle plate 304 is abutted and connected to the outside of the impurity outlet, and the baffle plate 304 is connected to the impurity collecting box 303 through an electric push rod. A discharge outlet 102 is provided on the other side wall of the screening box 1. The discharge outlet 102 is matched with a group of screening buckets 502 located at the bottom end of the screening box 1, and a discharge valve is provided outside the discharge outlet 102 for discharging rapeseed.

In this embodiment, the rapeseed raw material is placed in the storage box 201, and the controller is used to start the motor to drive the rotating rod to rotate, thereby driving a plurality of groups of material leveling blades 202 to rotate, so that the rapeseed raw material in the storage box 201 can be pushed downward to discharge the material. When the rotating rod stops rotating, the raw material stops being discharged. The discharge speed can be adjusted by controlling the rotation speed of the motor.

The controller starts the fan 301 to suck the lighter impurities in the evenly falling raw materials into the impurity removal box 3, and the impurities are intercepted by the filter 302. At the same time, the dust in the raw materials can be absorbed to reduce air pollution. Under the action of the impurities' own gravity, they fall along the filter 302 and are collected in the impurity collection box 303;

Then the raw material falls onto the screening assembly, and can be filtered step by step through the cooperation of a plurality of screening buckets 502 and material brushes 503, so that the rapeseed and the heavy impurities can be screened out, and the heavy impurities can be screened out step by step, thereby improving the screening efficiency of the rapeseed raw material;

After screening is completed, the controller starts the electric push rod to drive the baffle plate 304 away from the impurity discharge port. The continued rotation of the material brush 503 can discharge the screened impurities along the impurity discharge port into the impurity collecting box 303. The rapeseed can be discharged by starting the discharge valve on the discharge port 102, making discharge more convenient and quick.

In this embodiment, pressing the pressing plate 4 causes the pressing rod to move toward the inside of the dust collecting box 3, so that the spring 401 is compressed, and then the dust collecting brush 402 moves downward along the filter screen 302 to push the dust attached to the filter screen 302 downward into the dust collecting box 303, thereby preventing the filter screen 302 from being blocked by lighter impurities and dust in the rapeseed raw material. When the pressing plate 4 is released, the dust collecting brush 402 is driven to move upward along the filter screen 302 under the recovery action of the elastic force of the spring 401 to return to the initial state.
