[0002] Grain and oil impurity separation equipment is mainly used for removing impurities in grain and oilseed processing to ensure product quality and improve processing efficiency. This equipment typically removes impurities from raw materials, such as stones, dust, weed seeds, and insect eggs, through various methods to obtain purer grain and oil products.

[0003] For example, a grain impurity separation device with announcement number CN222535524U relates to the technical field of grain processing. This utility model includes a shell with a discharge port and an exhaust port at both ends. A collection box is placed at the discharge port, and a feed port is provided on the shell. A filter screen is fixedly installed at the feed port inside the shell. A fan unit is fixedly installed inside the shell, and a screening frame is slidably installed inside the shell. A vibration assembly is installed on the shell, including a drive shaft rotatably mounted on the upper surface of the shell. Turntables are fixedly installed at both ends of the drive shaft. A cleaning assembly is installed on the lower surface of the screening frame. By setting the cleaning assembly, the purpose of cleaning the screen mesh is achieved, preventing screen mesh blockage and affecting grain screening and impurity removal. By setting the vibration assembly, the purpose of using the vibration assembly to drive the screening frame to vibrate and screen the grain for impurity removal is achieved.

[0004] The aforementioned patent proposes that by setting up a vibration component, the purpose of screening and removing impurities from grain can be achieved by using the vibration component to drive the screening frame to vibrate. However, during the use of the grain and oil impurity separation equipment, since the light impurities in the grain are screened by wind power, and the grain contains a certain amount of moisture, impurities are easily adhered to its surface. During the screening, this will affect the overall screening effect and result in poor grain impurity separation effect. Utility Model Content

The grain is dried by the drying chamber 31, and the grain is stirred by the second motor 34 and the stirring rod 36 to make the grain dry evenly, which is conducive to the subsequent separation of impurities.

[0025] A mounting base 311 is installed on the inner top wall of the drying oven 31. A heating tube 312 is installed on the inner side of the mounting base 311. A vent 313 for moisture discharge is embedded in the side wall of the drying oven 31. A temperature sensor 315 is also installed on the inner wall of the drying oven 31 to monitor the temperature inside the drying oven 31. A temperature controller 314 is installed on the outer wall of the drying oven 31. The temperature controller 314 is connected to the heating tube 312. The voltage of the heating tube 312 can be adjusted and the temperature of the heating tube 312 can be adjusted by means of the temperature controller 314.

[0026] The separating frame 1 includes an opening 11 and an opening 12, both of which are located on the side wall of the separating frame 1. Two sets of openings 12 are provided. Inside the separating frame 1, a screen 13 and a screen 14 are installed at an angle, with the screen 14 positioned below the screen 13. The screen holes on the surfaces of the screens 13 and 14 are of different sizes. A guide frame 15 is installed on the outer side of the opening 12. A fan component 16 is fixedly installed at the top inside the separating frame 1. A filter screen is also installed at the front end. The blower 16 is used to blow the grain discharged from the guide frame 15 so that light impurities can be discharged from the opening 11. A guide block 17 is installed on the bottom wall of the separation frame 1. Screening components 18 are installed at the lower ends of screen 13 and screen 2 14. A drive component 19 is installed at the back end of the separation frame 1. The drive component 19 drives the screening component 18 to knock on screen 13 and screen 2 14, which can screen the grain on screen 13 and screen 2 14.

[0027] The drive unit 19 includes a base 191 and a motor 192 mounted inside the base 191. The output end of the motor 192 is connected to a shaft 193, and a shaft 193 is also mounted on the side wall of the separation frame 1. Both sets of shafts 193 are fitted with synchronous pulleys 194 on their outer sides, and synchronous belts 195 are wound around the synchronous pulleys 194. When the motor 192 is started, it can drive the shaft 193 connected to it to rotate, and in conjunction with the synchronous pulleys 194 and the synchronous belts 195, it can drive the other set of shafts 193 to rotate.

[0028] The screening component 18 includes a rotating shaft 181 and a cam 182 sleeved on the outside of the rotating shaft 181. One end of the rotating shaft 181 is connected to the shaft rod 193.

The other end of the connecting spring 184 is connected to a movable column 185. The bottom walls of screen one 13 and screen two 14 are respectively connected to the top of the movable column 185. When the two sets of shaft rods 193 rotate, they can drive the rotating shaft 181 and the cam 182 to rotate. The two sets of cams 182 strike screen one 13 and screen two 14 respectively. At this time, the movable column 185 can slide up and down in the fixed sleeve 183 and squeeze or stretch the connecting spring 184.

[0029] In this embodiment: the grain is fed from the feed frame 32 into the drying basket 33. At the same time, the heating tube 312 is activated to generate heat and the motor 34 is activated to drive the stirring rod 36 to rotate, which can stir the grain and make it evenly irradiated. This can effectively reduce the moisture on the grain and prevent light impurities from adhering to the grain and affecting the subsequent separation. The dried grain can enter the separation frame 1 through the feed frame 35. The blower 16 blows the falling grain so that the light impurities in the grain can be discharged from the opening 11, effectively separating the light impurities. Then the grain can fall onto the screen 13, and the drive component 19 drives the screening component 18 to knock it, effectively screening the grain.

[0030] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 The feeding frame 35 includes an electric push rod 351 and a baffle 352 connected to the telescopic end of the electric push rod 351. The electric push rod 351 is connected to a control panel via a cable, and the operation of the electric push rod 351 can be started by the control panel. The baffle 352 is slidably connected inside the feeding frame 35.

[0031] The slowing component 37 includes a guide plate 371 and a vibrating block 372 installed on the side wall of the guide plate 371. The vibrating block 372 is externally connected to the output end of a vibration motor. The guide plate 371 is inclinedly arranged inside the feeding frame 35. The guide plate 371 can reduce the speed of grain falling.

[0032] In this embodiment: after the grain is dried, the electric push rod 351 is activated in the reverse direction, so that the baffle 352 can move away from the feeding frame 35, so that the grain can be discharged from the feeding frame 35. With the help of the guide plate 371, the falling speed of the grain can be slowed down, which is conducive to the blowing of the grain by the blower 16, so that light impurities can be blown away, which is conducive to the separation of light impurities.

[0033] It should be noted that by adjusting the output voltage of the thermostat 314, the current in the heating tube 312 can be changed, thereby adjusting the heat generated by the heating tube 312. This is not an innovative part of this application and is common knowledge. Those skilled in the art are capable of conceiving of the specific structure and layout.
