[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-10 A grain air vortex transfer device includes a conveying pipe 1 and a deceleration feed pipe 4. The inner wall of the conveying pipe 1 is provided with a spiral guide groove 103. A feed pipe 101 is provided at the top of one end of the conveying pipe 1, and a discharge pipe 102 is provided at the bottom of the other end of the conveying pipe 1. A vortex output pipe 2 is fixedly installed at one end of the conveying pipe 1. An air intake grille 21 is provided at one end of the vortex output pipe 2. A fan 5 is fixedly installed on the outside of the air intake grille 21. A spiral guide vane 7 is provided inside the vortex output pipe 2. One end of the spiral guide vane 7 is fixedly connected to the air intake grille 21, and the other end of the spiral guide vane 7 is fixedly connected to the top of the inner wall of the vortex output pipe 2 through a suspension connecting bracket 71.

[0029] Among them, an installation ring 6 is fixedly installed at the top outer end of the feed pipe 101, and slots 61 are opened on both sides of the inner wall of the installation ring 6, and sliding grooves 611 are opened on both sides of the inner wall of the slots 61.

[0030] Meanwhile, vertical plates 3 are fixedly installed at both ends of the top of the mounting ring 6, and movable grooves 31 are opened on the inner side of the vertical plates 3.

[0031] Furthermore, the lower end of the deceleration feed tube 4 is located inside the mounting ring 6. Insert blocks 43 are provided on both sides of the lower end of the deceleration feed tube 4. The insert blocks 43 are slidably inserted into the slot 61. A spring 10 is fixedly installed on one end of the insert block 43. The other end of the spring 10 is fixedly connected to one end of the slot 61. The spring 10 realizes the horizontal vibration of the deceleration feed tube 4.

[0032] Meanwhile, sliders 431 are provided on both sides of the insert 43. The sliders 431 slide within the groove 611, making the reciprocating motion of the insert 43 within the slot 61 more stable.

[0033] Furthermore, movable blocks 42 are provided on both sides of the outer wall of the deceleration feed pipe 4. The movable blocks 42 are movably located in the movable groove 31. Springs 11 are fixedly installed on both sides of the movable blocks 42. The other ends of the two springs 11 are fixedly connected to the two sides of the movable groove 31 respectively. The springs 11 realize the horizontal vibration of the deceleration feed pipe 4.

[0034] Meanwhile, a connecting seat 62 is provided at one end of the mounting ring 6, and an electric push rod 9 is fixedly installed on the connecting seat 62. The electric push rod 9 is connected to the deceleration feed pipe 4 through the connecting block 41. The electric push rod 9 performs reciprocating motion, thereby driving the deceleration feed pipe 4 to achieve horizontal vibration, so that the grain can pass through the screen 8 and enter the conveying pipe 1 to be conveyed.

[0035] Furthermore, a screen 8 is installed inside the deceleration feed pipe 4 via a T-shaped mounting piece 12. This screen intercepts impurities while slowing down the speed at which the grain enters the conveying pipe 1, thus preventing a large amount of grain from entering the conveying pipe 1, disrupting the vortex field, and accumulating inside the conveying pipe 1, which would prevent the grain from being conveyed.

[0036] In this embodiment, the electric push rod 9 is activated to reciprocate, thereby driving the deceleration feed pipe 4 to reciprocate synchronously. Spring 10 and spring 21 are continuously squeezed and reset, causing the deceleration feed pipe 4 to vibrate horizontally. At the same time, the blower 5 is activated, and the blower 5 draws in external air into the vortex output pipe 2. Then, under the action of the spiral guide vane 7, it is forced to rotate, thereby forming a three-dimensional spiral vortex field. Under the action of the spiral guide groove 103, the stability of the vortex field is improved. Then, the grain is poured into the deceleration feed pipe 4. Under the action of horizontal vibration, the grain passes through the screen 8 and enters the center of the vortex field. It is wrapped and accelerated by the rotating airflow, realizing "suspended" conveying. Then, it is discharged through the discharge pipe 102. Some larger impurities are intercepted by the screen 8. While removing larger impurities, the grain enters the conveying pipe 1 more slowly, avoiding a large amount of grain entering the conveying pipe 1, which would destroy the vortex field and accumulate in the conveying pipe 1, making it impossible to convey.

[0037] At the same time, the screws will remove the T-shaped mounting piece 12, and then the screen 8 can be removed for cleaning. When other grains need to be transported, the screen 8 can be freely replaced according to the diameter of the grain particles.

[0038] In this invention, the fan 5 draws in air into the vortex output pipe 2, and through the spiral guide vanes 7, it is forced to rotate, forming a three-dimensional spiral vortex field. Grain particles fall from the feed pipe 101 into the center of the vortex field, are enveloped and accelerated by the rotating airflow, and achieve "suspended" conveying, which reduces the breakage rate of grain during the conveying process.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
