DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0033] ​In addition, elements in the application can be referred to as "fixed" or "disposed" on another element, which can be directly on another element or can have a middle element. When an element is considered "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only implementation.

[0034] Please refer to Figures 1-7 In the embodiment of the application, a Morel cultivation and planting mulching film winding and covering machine comprises a frame 1, two drive wheels 2 are arranged on one side of the frame 1, and two steering wheels 3 are arranged on the other side of the frame 1; the Morel cultivation and planting mulching film winding and covering machine further comprises:

[0035] A winding roller 4 is rotatably installed at the bottom of the frame 1 and used for winding the mulching film. The bottom of the frame 1 is movably provided with a drive roller 5 through an elastic supporting mechanism. The drive roller 5 is located above the winding roller 4 and abuts against the winding roller 4. The radius of the drive roller 5 is equal to that of the drive wheel 2.

[0036] A pressing roller 6 is movably arranged below the frame 1 and connected with two groups of vertical assembly mechanisms respectively arranged on both sides of the frame 1. The pressing roller 6 is located on the side of the winding roller 4 away from the steering wheel 3. The mulching film pulled out from the winding roller 4 can bypass the pressing roller 6 to form a transmission route of the mulching film.

[0037] A power mechanism is installed on the frame 1 and used for driving the two drive wheels 2 to rotate. The power mechanism is connected with the rotating shaft of the drive roller 5 through a sliding sleeve fitting mechanism and a transmission mechanism. The sliding sleeve fitting mechanism can cooperate with the vertical assembly mechanism. When the connection state of the sliding sleeve fitting mechanism and the transmission mechanism is disconnected, the vertical assembly mechanism is triggered to enable the pressing roller 6 to perform a lifting action.

[0038] An air blowing mechanism is arranged on the frame 1 and connected with the sliding sleeve fitting mechanism. The air blowing mechanism can blow air to the mulching film during the mulching process.

[0039] It should be noted that in actual use, the machine can be moved by a tractor. A cab can be arranged on the frame 1. The machine can be moved by a worker in the cab during operation.

[0040] Secondly, the winding roller 4 and the frame 1 are detachably connected to enable the winding roller 4 to be replaced when the winding roller 4 is damaged. Figure 1For example, when the frame 1 moves, the drive wheel 2 rotates clockwise. Through the transmission of the sliding engagement mechanism and the transmission mechanism, the drive roller 5 rotates clockwise, and then the winding roller 4 rotates counterclockwise. At this time, the winding roller 4 should release the mulch film on it. Therefore, when laying the winding roller 4, attention should be paid to its installation orientation.

[0041] During operation, one end of the mulch film is pulled out from the winding roller 4 and passes around the pressure roller 6. The pressure roller 6 then presses the pulled-out mulch film onto the ground. Subsequently, the power mechanism starts working, driving the drive wheel 2 to rotate, thereby moving the machine. At the same time, the power mechanism drives the sliding engagement mechanism to move, which in turn drives the drive roller 5 to rotate. Thus, the drive roller 5 acts on the winding roller 4, releasing the mulch film from it. The radii of the drive roller 5 and the drive wheel 2 are equal, and under the transmission of the sliding engagement mechanism and the transmission mechanism, the rotational speeds of the drive wheel 2 and the drive roller 5 are equal. Therefore, the length of the mulch film released is equal to the length of the machine movement, ensuring that the tension on the mulch film is balanced during operation and preventing the mulch film from tearing due to stress. In addition, the sliding engagement mechanism also drives the air blowing mechanism to move, which blows air onto the mulch film on the ground, causing the film to adhere to the ground and improving the mulching effect.

[0042] After the operation is completed, the operator can control the sliding engagement mechanism to disconnect from the transmission mechanism, so that the film on the winding roller 4 is not released during the subsequent transfer of the machine. During this process, the vertical assembly mechanism is triggered, which can cause the pressure roller 6 to perform an upward action, so as to prevent the outer wall of the pressure roller 6 from being adhered to the stains, which would cause the film to be torn by the stains during the next use.

[0043] In summary, through the cooperation between various mechanisms and components, the power mechanism drives the drive wheel 2 to rotate during operation, thereby moving the machine. At the same time, the power mechanism can drive the drive roller 5 to rotate through the sliding engagement mechanism and the transmission mechanism. The radius and rotation speed of the drive roller 5 and the drive wheel 2 are equal, thus ensuring that the length of the mulch film released is equal to the length of the machine movement. This ensures that the tension force on the mulch film is balanced during operation, preventing the mulch film from breaking due to stress. This effectively solves the drawbacks of mechanized mulch film covering machine operation.

[0044] Please refer to it again. Figure 2 and Figure 6The elastic support mechanism includes two columns 23 slidably mounted on the frame 1, an assembly plate 18 slidably mounted on the frame 1 and fixedly connected to the two columns 23, and two first cylindrical springs 24 respectively sleeved on the outer periphery of the two columns 23. The drive roller 5 is rotatably mounted on the assembly plate 18, and one end of the first cylindrical spring 24 is connected to the assembly plate 18, and the other end is connected to the frame 1.

[0045] It should be emphasized that during the operation, the first cylindrical spring 24 is in a compressed state, which enables the drive roller 5 to press the mulch film on the winding roller 4. When the drive roller 5 rotates, it can cause the mulch film on the winding roller 4 to be released, and the speed at which the mulch film is released is consistent with the linear speed of the drive roller 5.

[0046] Please refer to it again. Figure 1 , Figure 4 , Figure 5 as well as Figure 6 The power mechanism includes a drive motor 7 mounted on the frame 1. The output shaft of the drive motor 7 is connected to the axles of the two drive wheels 2 via a third transmission belt 31. The sliding engagement mechanism includes a rotating shaft 9 rotatably mounted on the frame 1 and a sleeve 10 slidably engaged with the rotating shaft 9. The rotating shaft 9 is connected to the output shaft of the drive motor 7 via a bevel gear set 8. A first bevel gear 14 is fixed to one end of the sleeve 10 away from the drive motor 7. A transmission shaft 16 is also rotatably mounted on the frame 1. The transmission shaft 16 is connected to the rotating shaft of the drive roller 5 via the transmission mechanism, and a second bevel gear 15 that engages with the first bevel gear 14 is fixed on the transmission shaft 16.

[0047] The rotating shaft 9 and the sleeve 10 are provided with a limiting structure. The sleeve 10 is connected to a pneumatic component installed on the frame 1. The pneumatic component can drive the first bevel gear 14 to mesh or separate from the second bevel gear 15, and also cooperates with the vertical assembly mechanism.

[0048] In detail, the bevel gear set 8 includes a first bevel gear fixedly mounted on the output shaft of the drive motor 7 and a second bevel gear fixedly mounted on the end of the rotating shaft 9 facing the drive motor 7, and the second bevel gear meshes with the first bevel gear.

[0049] The limiting structure includes two strip-shaped protrusions 901 formed on the outer wall of the rotating shaft 9 and two strip-shaped grooves 1001 provided on the inner wall of the sleeve 10. The strip-shaped grooves 1001 are adapted to the strip-shaped protrusions 901, and both are parallel to the central axis of the rotating shaft 9 and the sleeve 10. The pneumatic assembly includes a connecting plate 12 slidably disposed on the frame 1 and a cylinder 11 mounted on the frame 1 with its movable end fixedly connected to the connecting plate 12. The connecting plate 12 is rotatably connected to the sleeve 10, and a pulley 13 cooperating with the vertical assembly mechanism is also mounted on the connecting plate 12.

[0050] The vertical assembly mechanism includes a guide block 25 fixed to the side of the frame 1 and a vertical arm 26 slidably disposed on the guide block 25. The pressure roller 6 is rotatably mounted between the two vertical arms 26, and a vertical rod 28 is fixed on the vertical arm 26 by a protrusion 27. The vertical rod 28 is slidably connected to the guide block 25. A second columnar spring 29 is also sleeved on the outer periphery of the vertical rod 28. The two ends of the second columnar spring 29 are respectively connected to the protrusion 27 and the guide block 25. A driven rod 30 is also fixed on the vertical arm 26. An inclined portion 3001 that cooperates with the pulley 13 is formed on the driven rod 30.

[0051] When the drive motor 7 is working, its output shaft will drive the rotating shaft 9 to rotate through the bevel gear set 8. Then, the rotating shaft 9 will drive the sleeve 10 to rotate through the strip protrusion 901 and the strip groove 1001. When the first bevel gear 14 and the second bevel gear 15 are in a meshing state, the sleeve 10 will drive the transmission shaft 16 to rotate through the first bevel gear 14 and the second bevel gear 15, so that the transmission shaft 16 drives the drive roller 5 to rotate through the transmission mechanism.

[0052] After the operation is completed, in order to prevent the film on the winding roller 4 from being released and wasted during the machine transfer process, the operator can control the cylinder 11 to drive the connecting plate 12 to drive the sleeve 10 to slide on the rotating shaft 9 toward the drive motor 7. Correspondingly, the first bevel gear 14 and the second bevel gear 15 are separated, and the linkage between the drive wheel 2 and the drive roller 5 is released. During this process, the pulley 13 will act on the inclined part 3001, causing the driven rod 30 to give way. The driven rod 30 will drive the vertical arm 26 to move upward, and the pressure roller 6 will be lifted to avoid contamination of the pressure roller 6.

[0053] The transmission mechanism includes a first connecting rod 19 and a second connecting rod 20 rotatably connected by a shaft 17. The end of the first connecting rod 19 away from the shaft 17 is rotatably connected to the transmission shaft 16, and the end of the second connecting rod 20 away from the shaft 17 is rotatably connected to the rotation shaft of the drive roller 5. The shaft 17 is connected to the transmission shaft 16 via a first transmission belt 21 and is also connected to the rotation shaft of the drive roller 5 via a second transmission belt 22.

[0054] During the operation, as the work progresses, the plastic film on the winding roller 4 is gradually consumed. As a result, the first cylindrical spring 24 gradually releases its elastic potential energy to keep the drive roller 5 in contact with the winding roller 4. Therefore, the drive roller 5 gradually moves downward, and the angle between the first connecting rod 19 and the second connecting rod 20 gradually increases, ensuring that the linkage between the transmission shaft 16 and the drive roller 5 is maintained.

[0055] Please refer to it again. Figure 1 and Figure 7 The air-blowing mechanism includes a reciprocating plate 35 slidably mounted on the frame 1, two gears 36 rotatably mounted on the bottom of the frame 1 and located on both sides of the reciprocating plate 35, and a disc 33 rotatably mounted on the frame 1. The rotating shaft of the disc 33 is connected to the rotating shaft 9 via a fourth transmission belt 32. A push-pull rod 34 is provided between the disc 33 and the reciprocating plate 35. One end of the push-pull rod 34 is rotatably connected to the reciprocating plate 35, and the other end is rotatably connected to the eccentric part of the disc 33. Both sides of the reciprocating plate 35 are provided with teeth that mesh with the gears 36. The rotating shaft of the gears 36 is fixedly connected to a nozzle 37 via a pipe 38, and the pipe 38 is rotatably and sealingly connected to the air outlet of the air pump.

[0056] When the rotating shaft 9 rotates, it will drive the disc 33 to rotate via the fourth transmission belt 32. Then, the disc 33 will drive the reciprocating plate 35 to reciprocate up and down on the frame 1 via the push-pull rod 34. Correspondingly, the teeth on the side of the reciprocating plate 35 will drive the gear 36 to reciprocate. The tube 38 will drive the nozzle 37 to swing back and forth. The air pump works as the nozzle 37 swings towards the outside of the frame 1, blowing air onto the mulch film on the ground, causing the film to adhere to the ground and improving the mulching effect.
