[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example 1

[0030] Please combine Figures 1 to 5 A cotton fertilizer preparation device includes a cylinder 1. The outer wall of the cylinder 1 has a feed valve 2 for material input and a discharge valve 3 for material output. A first stirring rod 6 is eccentrically arranged inside the cylinder 1 and parallel to its axis. An actuating mechanism is provided in the cylinder 1. The actuating mechanism can drive the first stirring rod 6 to move in the cylinder 1 to fully stir the material in the cylinder 1.

[0031] The actuation mechanism includes a drive shaft 4 concentrically inserted into the top wall of the inner cylinder 1, a cross arm 5 provided on the outside of the drive shaft 4, and a first stirring rod 6 installed at the bottom of the cross arm 5.

[0032] A motor 18 is installed on the cylinder 1. The output shaft of the motor 18 passes through the inside of the cylinder 1 and is connected to the drive shaft 4.

[0033] The cross arm 5 has a movable groove (not shown) parallel to its extension direction. A base 8 is slidably mounted in the movable groove. A connecting rod 7 coaxial with the first stirring rod 6 is inserted on the base 8. The top of the first stirring rod 6 is fixed to the bottom of the connecting rod 7.

[0034] In this embodiment, the output shaft of the motor 18 drives the transmission shaft 4 to rotate, which in turn drives the horizontal arm 5 to rotate circumferentially. The horizontal arm 5 then drives the first stirring rod 6 to move circumferentially in the cylinder 1 via the connecting rod 7, thereby stirring the raw materials in the cylinder 1.

[0035] The base 8 is slidably engaged in the movable groove (not shown), and a first spring 9 is provided between one side of the base 8 and the wall of the movable groove.

[0036] In this embodiment, when the horizontal arm 5 rotates circumferentially, the connecting rod 7 can move centrifugally in the movable groove (the first spring 9 is stretched and deformed). When the horizontal arm 5 gradually stops rotating, the connecting rod 7 can move centripetally in the movable groove (the first spring 9 gradually returns to its original position). When the first stirring rod 6 rotates eccentrically circumferentially in the cylinder 1, it will also reciprocate in the extension direction of the horizontal arm 5 as the speed of the transmission shaft 4 changes, thereby expanding the stirring coverage area of ​​the raw materials in the cylinder 1 and improving the stirring effect and efficiency.

[0037] In other embodiments, the reciprocating movement of the first stirring rod 6 in the extension direction of the cross arm 5 can be further further provided by setting a limiting groove 11 on the top wall of the inner cylinder 1, a fixing plate 10 is provided below the limiting groove 11, a limiting block 12 is provided on the top of the fixing plate 10, the limiting block 12 is slidably locked in the limiting groove 11, and the connecting rod 7 is rotatably set at the bottom of the fixing plate 10.

[0038] The limiting groove 11 has an overall wave-shaped closed-loop structure.

[0039] A synchronous shaft (not shown) parallel to the connecting rod 7 is inserted into the fixed plate 10. A roller 13 that contacts the outer wall of the limiting groove 11 is provided at the top of the synchronous shaft, and a first gear 14 is provided at the bottom. A second gear 15 that intermittently cooperates with the first gear 14 is sleeved and fixed on the outer side of the connecting rod 7. The connecting rod 7 is rotatably inserted into the base 8.

[0040] The first gear 14 is a toothed gear.

[0041] In this embodiment, the cross arm 5 drives the connecting rod 7 to move circumferentially, which in turn drives the limiting block 12 to move within the limiting groove 11 via the fixed plate 10. The limiting block 12, within the wave-shaped closed-loop limiting groove 11, drives the base 8 to reciprocate within the movable groove. This, in turn, drives the first stirring rod 6 to reciprocate in the extending direction of the cross arm 5 via the connecting rod 7. Simultaneously, the roller 13 rotates upon contact with the limiting groove 11, causing the first gear 14 to intermittently drive the second gear 15, the connecting rod 7, and the first stirring rod 6 itself to rotate. This expands the stirring coverage area of ​​the raw materials inside the cylinder 1, improving the stirring effect and efficiency.

[0042] Example 2

[0043] This embodiment is an improvement on embodiment 1. In order to further expand the stirring area of ​​the raw materials and improve the stirring efficiency and effect, this embodiment has multiple circumferentially evenly distributed receiving grooves 16 axially opened on the outer side wall of the connecting rod 7 near the bottom. Each receiving groove 16 is rotatably connected to a second stirring rod 17 that can be deflected outward, further expanding the stirring coverage area of ​​the raw materials in the cylinder 1 and improving the stirring effect and efficiency.

[0044] One end of the second stirring rod 17 is connected to the top wall of the receiving tank 16 via a coil and a coil spring. When the coil spring is not deformed, the second stirring rod 17 is contained in the receiving tank 16. When the connecting rod 7 rotates, the second stirring rod 17 will deflect and tilt out of the receiving tank 16 under the action of centrifugal force, so as to further expand the stirring coverage area of ​​the raw materials in the cylinder 1.

[0045] A fixed third gear 19 is provided on the outer wall of the connecting rod 7, and a fourth gear 20 that rotatably engages with the third gear 19 is provided on the outer wall of the connecting rod 7. A spool 21 is coaxially fixed on the fourth gear 20, and a pull rope is wound on the spool 21. A sliding groove 22 is axially opened on the outer wall of the second stirring rod 17. A third stirring rod 24 perpendicular to the second stirring rod 17 is slidably engaged in the sliding groove 22. The third stirring rod 24 is connected to the sliding groove 22 by a second spring 23. When the second spring 23 is not deformed, the third stirring rod 24 is located on the second stirring rod 17 at the end near the spool.

[0046] When the second stirring rod 17 deflects and tilts out of the receiving tank 16 under the action of centrifugal force, the fourth gear 20 will move and rotate around the outer periphery of the third gear 19, thereby driving the reel 21 to rotate and releasing the pull rope. Under the elastic release action of the second spring 23, the third stirring rod 24 moves away from the spool to further expand the stirring coverage area of ​​the raw materials in the cylinder 1, improving the stirring effect and efficiency. When the first gear 14 disengages from the second gear 15, the speed of the connecting rod 7 gradually decreases, the centrifugal force on the second stirring rod 17 decreases, the coil spring drives the second stirring rod 17 to move towards the receiving tank 16, and the third stirring rod 24 also gradually returns to its original position to pull back the raw materials that were originally pushed by the stirring rod in the cylinder 1, so as to make the mixture uniform.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
