[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, the utility model provides a grain dryer with a grain impurity removal function, comprising a grain dryer body 1, a motor 2 fixedly mounted on one side of the grain dryer body 1, a long rotating rod 3 fixedly mounted on the output shaft of the motor 2, a section of the long rotating rod 3 extending into the grain dryer body 1 and rotatably connected to the grain dryer body 1, and an impurity removal mechanism provided inside the grain dryer body 1;

[0024] The impurity removal mechanism includes a power component and an impurity removal component. The impurity removal component includes an auger 2 12 fixedly mounted on the outer wall of the long rotating rod 3. A impurity removal cylinder 2 11 is fixedly mounted inside the grain dryer body 1. The auger 2 12 and the long rotating rod 3 are both arranged in the impurity removal cylinder 2 11. An auger 10 is fixedly sleeved on the outer wall of the impurity removal cylinder 2 11. A impurity removal cylinder 8 is rotatably mounted inside the grain dryer body 1. The impurity removal cylinder 2 11 and the auger 10 are both arranged in the impurity removal cylinder 8. A number of circular grooves 2 14 are provided on the outer wall of the impurity removal cylinder 2 11, and a number of circular grooves 13 are provided on the outer wall of the impurity removal cylinder 8.

[0025] By starting the motor 2, the output shaft of the motor 2 drives the long rotating rod 3 to rotate, and then drives the auger 2 12 and the auger 1 10 to rotate synchronously. After the grain is fed into the impurity removal barrel 2 11, under the joint action of the auger and the impurity removal barrel, the auger 2 12 is located inside the impurity removal barrel 2 11. The driving force generated by its rotation causes the grain to move along the axial direction of the impurity removal barrel, and preliminary stirring and mixing are performed in the process. At the same time, the auger 10 is set on the outer wall of the impurity removal barrel 2 11, and its rotation further enhances the stirring effect of the grain and promotes the separation of the grain and impurities. As the grain flows and stirs in the impurities in the impurities barrel 2 11, they are gradually separated due to the difference in physical properties such as density and shape with the grain. The impurities can be discharged through the circular groove 13 and the circular groove 2 14 to ensure the quality of the final product.

[0026] like Figure 2 As shown, a plurality of connecting strips 15 are hingedly mounted on the outer wall of the middle portion of the de-cluttering barrel 8, and impact balls 16 are fixedly mounted at the ends of the plurality of connecting strips 15.

[0027] When the impurity removal barrel 8 rotates under the drive of the power component, the connecting bar 15 and the impact ball 16 will also rotate and generate centrifugal force, so that the impact ball 16 can continuously collide with the impurity removal barrel 8. Since the impact ball 16 has a certain mass and hardness, it can generate enough impact force to break the adhesion between the grain and impurities, and can even shake off impurities hidden in the gaps of the grain. In addition, the shape and distribution of the impact ball have also been carefully designed to ensure that it can cover every corner of the impurity removal barrel, thereby achieving comprehensive impurity removal.

[0028] like Figures 2 to 3 As shown, the power assembly includes a gear 1 4 fixedly mounted on the output shaft of the motor 2, a short rotating rod 5 is rotatably mounted on the outer wall of one side of the grain dryer body 1, one end of the short rotating rod 5 extends into the grain dryer body 1, and a gear 2 6 and a gear 3 7 are fixedly sleeved on the outer wall of the short rotating rod 5, and the gear 2 6 is meshed with the gear 1 4.

[0029] The power is transmitted to gear 1 4 through the long rotating rod 3, and gear 1 4 engages with gear 2 6, thereby driving the short rotating rod 5 to rotate, and finally driving the rotation of the impurity removal drum 1 8, thereby realizing the functions of drying and impurity removal.

[0030] like Figure 4 As shown, teeth 9 are fixedly mounted on the outer wall of the impurity removal drum 1 8 close to the motor 2 . The teeth 9 are distributed in a circular array with the center of the impurity removal drum 1 8 as the axis, and the teeth 9 are engaged with the gear 3 7 .

[0031] Through the meshing of gear three 7 and teeth 9, gear three 7 drives teeth 9 to rotate when it rotates, and teeth 9 drives debris removal drum one 8 to rotate, so that the entire transmission system can operate in an efficient and stable state.

[0032] like Figure 4 As shown, the sizes of the circular groove 13 and the circular groove 2 14 are inconsistent, and the diameter of the circular groove 2 14 is larger than the diameter of the circular groove 13 .

[0033] The circular groove design of different diameters helps to guide the grain to form a more reasonable flow path inside the dryer, promotes the rapid flow and distribution of grain, and the enhanced interaction can more effectively remove impurities in the grain and improve the impurity removal effect. By optimizing the material flow path and enhancing the impurity removal effect, it also helps to improve the overall drying efficiency of the dryer. The uniform distribution and rapid flow of grain in the dryer enable heat to be more evenly transferred to each grain, shortening the drying time and reducing energy consumption.

[0034] like Figure 2 As shown, gear three 7 is arranged inside the grain dryer body 1, gear two 6 is arranged outside the grain dryer body 1, and the pitch circle diameter value of gear two 6 is greater than the pitch circle diameter value of gear three 7.

[0035] Through the principle of gear transmission, that is, the large gear drives the small gear to reduce speed and increase torque. During the transmission process, although the speed is reduced, the torque transmitted to gear 3 7 is increased, thereby improving the efficiency of power transmission, allowing the rotating parts inside the dryer to obtain greater driving force, thereby improving the impurity removal and drying effects.

[0036] like Figure 3 As shown, a plurality of connecting strips 15 and impact balls 16 are designed to be distributed in a circular manner in the vertical direction with the center of the impurity removal barrel 8 as the axis, and are designed to be distributed at intervals in the vertical direction.

[0037] By setting the impact ball 16, it is ensured that the grain can be evenly impacted from all directions when passing through the impurity removal cylinder. This all-round and multi-angle impact effectively promotes the separation of impurities such as stones, soil blocks, weeds, etc. in the grain from the grain itself, and significantly improves the impurity removal efficiency.

[0038] The working principle and use process of this utility model:

[0039] The user first puts the grain into the impurity removal drum 2 11 of the grain dryer body 1, and then starts the motor 2. The output shaft of the motor 2 rotates to drive the gear 1 4 to rotate. The gear 1 4 meshes with the gear 2 6, thereby driving the gear 2 6 to rotate. The gear 2 6 drives the short rotating rod 5 and the gear 3 7 to rotate. The gear 3 7 meshes with the teeth 9, driving the teeth 9 and the impurity removal drum 1 8 to rotate. At the same time, the output shaft of the motor 2 drives the auger 2 12 to rotate, pushing the grain to move axially in the impurity removal drum 2 11 and performing preliminary stirring. and mixing, the auger 10 is fixedly sleeved on the outer wall of the impurity removing barrel 11, and the rotation of the impurity removing barrel 8 allows the impurities to enter the impurity removing barrel 8 through the circular groove 214 for further impurity removal and separation. The connecting strip 15 and the impact ball 16 hingedly installed on the outer wall of the middle part of the impurity removing barrel 8 rotate with the impurity removing barrel 8, generating centrifugal force and constantly colliding with the grain. The impact force of the impact ball 16 breaks the adhesion between the grain and impurities, and shakes off the impurities hidden in the gaps in the grain, further improving the impurity removal effect.
