[0037] Example 1:

[0038] Reference Figure 1-7 The present solution proposes a straw baling and wrapping device, comprising a base plate 1 and a feeding mechanism, an additive replenishment mechanism, a baler 7, and a wrapping mechanism sequentially arranged on the base plate 1, wherein:

[0039] The feeding mechanism includes an elevator 3 and a conveyor belt 4. The elevator 3 is used to transport straw, and the conveyor belt 4 is installed on top of the elevator 3 to receive straw.

[0040] In this solution, the additive replenishment mechanism includes a moisture content meter 6, a controller, and a spraying mechanism 5. The moisture content meter 6 measures the moisture content of the straw on the conveyor belt 4. The controller's signal input receives the moisture content information detected by the moisture content meter 6, and its signal output controls the spraying mechanism 5 to apply the corresponding amount of probiotic agent. The moisture content meter 6 uses an existing infrared measuring instrument, enabling rapid and accurate measurement of the straw moisture content, which is then automatically sprayed by the controller.

[0041] In this solution, the wrapping mechanism includes a positioning module and a wrapping module, wherein,

[0042] The positioning module is located at the discharge port of the baler 7 and is used to receive and fix the straw bale 19.

[0043] The wrapping module is positioned adjacent to the positioning module to cover the straw bale 19 with film.

[0044] As an optional embodiment of the present invention, the positioning module includes a supporting unit and a fixing unit. The supporting unit supports the bottom of the straw bundle 19, and the fixing unit is used to fix the straw bundle 19 from above.

The two sets of film-cutting blades 17 can approach the single film 2201 after cutting and lamination, and the two guide posts 27 can approach each other under the action of the push rod, thereby ensuring that the two ends of the single film 2201 are tightly adhered. (Refer to...) Figure 4 And 6, under the action of the guide post 27, the single film 2201 can be tightly covered with the straw bundle, and the ends of the single film 2201 can be tightly attached. This solution can also be equipped with an electric heating device on the surface of the guide post 27 for heat sealing the two ends of the single film 2201, which will make the effect even better.

[0049] In an optional embodiment of the present invention, the fixing unit includes a top frame and a telescopic mechanism (not shown) mounted on the top frame. The telescopic mechanism (not shown) extends and retracts longitudinally, and its power output end is connected to an insertion rod.

The telescopic mechanism can be an electric push rod, which is mounted on two guide plates 10 via a support frame, facilitating the pushing of the insertion rod into the straw bundle to fix its position, maintain stability during film wrapping, and ensure reliable operation.

[0050] Reference Figure 5As an optional embodiment of the present invention, the supporting unit includes a lifting mechanism 14, which may be an electric push rod, a hydraulic cylinder or a pneumatic cylinder. The output end of the lifting mechanism 14 is connected to two push rods 28. A support plate 36 is fixed at the top of the two push rods 28. A central hole 37 is opened in the center of the support plate 36. A mounting plate 44 is fixed below the support plate 36. The mounting plate 44 and the two push rods 28 are fixed together.

[0051] As an optional embodiment of the present invention, the mounting plate 44 is provided with a lower limiting mechanism. The lower limiting mechanism includes a guide seat 43 fixed in the middle of the mounting plate 44, a positioning column 38 slidably inserted into the guide seat 43, and two sets of lifting units that drive the positioning column 38 to rise and fall. The lower limiting mechanism is used to fix the position of the straw bundle from the bottom, keep it stable, and facilitate the use of the wrapping film.

[0052] The lifting unit includes an inner rod 42 that is slidably inserted into the mounting plate 44, a plug rod 32 fixed to the outer end of the inner rod 42, a movable rod 31 connected to the plug rod 32, and a drive unit that drives the movable rod 31 to move.

[0053] The drive unit includes a drive motor 29 fixed on the mounting plate 44, a gear 35 connected to the output shaft of the drive motor 29, a gear 34 meshing with the gear 35 and a turntable (not shown) coaxially mounted on the gear shaft of the gear 34, and a connecting rod 33 movably connected to the turntable at an eccentric position, the other end of the connecting rod 33 being movably connected to the movable rod 31.

[0054] As an optional embodiment of the present invention, the top of the top rod 28 is provided with a threaded groove, and a lifting rod is screwed on the threaded groove. A gear ring 40 is also sleeved on the outside of the lifting rod, and the gear 35 meshes with the gear ring 40.

[0055] Example 2:

[0056] Further improvements were made based on Example 1. To facilitate the arrangement of the bottom of the single sheet of film wrapped around the outside of the straw bundle, the bottom of the film was tucked under the straw bundle, as shown in the following example. Figure 7 A connecting rod 49 is fixed to the outside of the movable rod 31, and an end plate 30 is fixed to the end of the mounting plate 44. A movable rod 45 is longitudinally slidably connected to the side of the end plate 30. The bottom end 48 of the movable rod 45 is longitudinally slidably connected to the end plate 30. An inclined strip hole 47 is opened in the middle of the movable rod 45, and the connecting rod 49 is movably inserted into the strip hole 47. The top end 46 of the movable rod 45 is always lower than the bottom surface of the straw bundle 19.

[0057] Since the length of the film is greater than the height of the straw bundle, the bottom of the film is lower than the straw bundle. When the above scheme is working, the movement of the movable rod 31 causes the connecting rod 49 to slide along the strip hole 47, thereby raising the top 46. This causes the top 46 to move towards the center of the straw bundle while moving upward, so that the bottom of the film wrapped around the surface of the straw bundle is gathered under the straw bundle.

[0058] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. 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.
