[0029] Among them Figure 3 As shown, a pair of symmetrically arranged push-pull frames 10 are fixed obliquely to the upper surface of the support base 1. The push-pull frames 10 are conventional structures in the art and are composed of a pair of support rods obliquely fixed to the support base 1 and a push-pull rod fixed between the two support rods. By operating the push-pull frames 10, workers can easily operate the device. Specific embodiment two:

[0031] Based on the specific embodiment 1, Figure 3 As shown, the lifting assembly 2 includes a positioning frame 201 horizontally arranged above the movable plate 3; a pair of guide rods 202 and a threaded rod 203 arranged side by side are vertically arranged between the positioning frame 201 and the support seat 1; the upper and lower ends of the guide rod 202 are respectively fixed on the positioning frame 201 and the movable plate 3; a sliding sleeve 204 is provided on the guide rod 202; the sliding sleeve 204 is fixedly inserted into the movable plate 3; the upper and lower ends of the threaded rod 203 are respectively rotatably connected to the positioning frame 201 and the movable plate 3; the upper end of the threaded rod 203 is coaxially fixed to the output shaft of a second servo motor 205; the second servo motor 205 is screwed to a second mounting plate 206 with an L-shaped structure; the second mounting plate 206 is screwed to the positioning frame 201; a screw sleeve 207 is threaded on the threaded rod 203; the screw sleeve 207 is fixedly inserted into the movable plate 3. During use, the second servo motor 205 drives the threaded rod 203 to rotate, prompting the screw sleeve 207 to drive the movable plate 3 to move up and down along the axial direction of the guide rod 202 . Specific embodiment three:

[0033] Based on the specific embodiment 2, Figure 4-5 As shown, the rotating assembly 5 includes an N-shaped bracket 501; opposite ends of the bracket 501 are screwed to the upper edge of the carrier ring 4; horizontally arranged connecting shafts 502 are rotatably connected to opposite arms of the bracket 501; the proximal ends of the two connecting shafts 502 are welded to the circumferential sidewalls of the conveying cylinder 6; the connecting shafts 502 are radially arranged along the conveying cylinder 6; the middle arm of the bracket 501 is screwed to a vertical top plate 503; the top plate 503 is horizontally arranged; a conventional electric push rod 504 is tilted below the top plate 503; the tail end of the electric push rod 504 is rotatably connected to the end of the top plate 503 away from the bracket 501; the output end of the electric push rod 504 is rotatably connected to the upper edge of the first mounting plate 9.

[0034] Among them Figure 4 As shown, the vertical cross section of the carrying ring 4 is The carrier ring 4 has a cylindrical structure. A first handle 401 is vertically fixed to the upper edge of the carrier ring 4. When the conveying cylinder 6 is in a vertical position, the central axis of the conveying cylinder 6 deviates from the central axis of the carrier ring 4. By vertically fixing the first handle 401 to the upper edge of the carrier ring 4, it is convenient to rotate the carrier ring 4 to drive the conveying cylinder 6 around the central axis of the carrier ring 4, thereby adjusting the circumferential position of the conveying cylinder 6. By designing that the central axis of the conveying cylinder 6 deviates from the central axis of the carrier ring 4 when the conveying cylinder 6 is in a vertical position, sufficient space is left for the conveying cylinder 6 to tilt within the carrier ring 4, thereby facilitating the conveying cylinder 6 to tilt within the carrier ring 4.

[0035] Among them Figure 5-6As shown, a plurality of grain delivery holes 603 are axially arranged side by side on the lower circumferential side wall of the conveying cylinder 6; an arc-shaped baffle 11 corresponding to the grain delivery holes 603 is attached to the circumferential outer wall of the conveying cylinder 6; the inner surface of the arc-shaped baffle 11 is in contact with the cylindrical outer wall of the conveying cylinder 6; the upper and lower edges of the arc-shaped baffle 11 are integrally formed with a transmission ring 1101 coaxially arranged with the conveying cylinder 6; the transmission ring 1101 is rotatably sleeved on the outer circumference of the conveying cylinder 6; a pair of limiting convex rings 604 corresponding to the arc-shaped baffle 11 are axially welded to the circumferential outer wall of the conveying cylinder 6; the two limiting convex rings 604 are respectively arranged on the relative outer sides of the two transmission rings 1101, and the relative inner surfaces of the two limiting convex rings 604 are respectively in contact with the relative outer surfaces of the two transmission rings 1101; a second handle 1102 with a cylindrical structure is fixed to the upper outer wall of the arc-shaped baffle 11 along the radial direction of the conveying cylinder 6. By axially arranging a plurality of grain delivery holes 603 on the lower circumferential side wall of the conveying cylinder 6, when it is necessary to turn over a plurality of grain layers synchronously, the arc-shaped baffle 11 can be driven to rotate around the central axis of the conveying cylinder 6 through the second handle 1102 via the transmission ring 1101, causing the arc-shaped baffle 11 to deviate from the grain delivery hole 603, thereby causing the grain delivery hole 603 to be in an open state, thereby achieving the purpose of grain particles entering the conveying cylinder 6 from the grain delivery hole 603.
