[0020] How to use the soil film covering machine:

[0021] S1: The user connects the traction frame with an external agricultural machine to drive the overall movement of the device, places the mulch roller for covering on the mulch roller frame, pulls the ends of the mulch film so that both sides of the mulch film can pass through the bottom of the guide wheel, and starts the first motor and the second motor at the same time. The output gear of the first motor will drive the gear ring and the transmission gear rod to rotate synchronously, and the gear ring drives the wheel ring to rotate synchronously. The wheel ring will roll on the land to provide auxiliary power. At the same time, the transmission gear rod will drive the rotating frame to rotate synchronously, so that the collection bucket installed on the rotating frame rotates synchronously, so that the collection bucket can groove the land to take soil. Since the wheel ring is always in contact with the ground and the size of the part of the collection bucket extending out of the wheel ring is constant, the collection bucket can maintain a certain amount of soil collection to prevent the subsequent covering amount from being too small due to ground fluctuations;

[0022] S2: When the rotating frame drives the collecting bucket that has completed soil collection to rotate to the top of the collecting tube, the rotating frame will drive the force-bearing rod to move along the guide groove through the limit ball, so that the force-bearing rod can enter the straight inclined groove obliquely above the guide groove. At this time, the force-bearing rod will drive the limit ball away from the moving part, so that the limit ball no longer conflicts with the moving part corresponding to the limit, and the soil in the collecting bucket will exert pressure on the baffle connected to the moving part. At this time, the baffle will move under the action of its own weight and soil pressure, so that the baffle no longer blocks the collecting bucket, and the soil in the collecting bucket will fall into the collecting tube. At the same time, the soil in the collecting tube will enter the outer shell under the action of the inclined surface. When the force-bearing rod enters the arc groove obliquely below the guide groove again, the force-bearing rod will drive the limit ball to move synchronously, so that the limit ball pushes the baffle to reset through the moving part;

[0023] S3: At the same time, the driving gear of the second motor will drive the transmission gear to rotate, and the transmission gear will drive the two conveying screws to rotate synchronously. The spiral grooves on the two conveying screws rotate in opposite directions. The conveying screws will drive the connecting plate and the lifting plate to rotate synchronously. At this time, the storage groove on the lifting plate can collect the soil collected at the bottom of the shell, and the lifting plate drives the soil to move synchronously, so that part of the soil in the storage groove can enter the connecting channel first, and the remaining part of the soil in the storage groove will be discharged through the side discharge pipe with a large opening. In this process, the conveying screw will drive the soil in the connecting channel to move along the inner wall of the support tube, and the soil in the support tube will be discharged through the top discharge plate, thereby falling on the top of the external covering film, and the soil discharged from the side discharge pipe will fall on both sides of the covering film;

[0024] S4: During the rotation of the lifting plate, the lifting plate can push the force-bearing protrusion to move, so that the force-bearing protrusion will drive the transmission rod to move synchronously. During this process, the thrust rod on the other side of the transmission rod will move along the outer tube and the inclined groove on the lifting platform, so that the lifting platform can move downward. The lifting platform stretches the reset spring. At the same time, the lifting platform drives the loading frame installed at the bottom to move synchronously, so that the pressure wheel on the loading frame can compact the covered soil synchronously. When the lifting plate no longer applies pressure to the force-bearing protrusion, the reset spring can drive the lifting platform to reset and move through the reset action.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the rice-wheat saline-alkali land soil film covering machine and the use method can cover the soil on both sides and the top of the ground film at the same time, and the device can automatically compact the soil on both sides after the soil covering is completed, thereby improving the fixing effect of the device on the ground film, and at the same time, the soil collecting mechanism of the device can maintain a certain amount of soil collection to prevent the subsequent ground film covering amount from being too small, and the specific contents are as follows:

[0026] 1. The rotating frame is coaxially fixedly connected to the end of the rod body of the transmission gear rod, and a collecting bucket with equal angle distribution is fixedly installed on the rotating frame. The collecting bucket is arranged around the outer side of the collecting barrel, and a limiting groove with equal angle distribution is opened on the rotating frame. A moving part and a limiting ball are slidably installed on the inner wall of the limiting groove. A baffle is fixedly connected to the convex end of the moving part. When the baffle is fitted at the discharge port of the collecting bucket, it plays a sealing role. A force rod is fixedly connected to the outer wall of the limiting ball. The end of the force rod away from the limiting ball is fitted in the guide groove opened on the positioning plate. When the rotating frame drives the collecting bucket to rotate and collect the soil on the ground, the rotating frame will drive the limiting ball to move synchronously. When the limiting ball enters the inclined groove part of the guide groove, the limiting ball will be away from the moving part. At this time, the baffle can be separated from the collecting bucket, and the soil in the collecting bucket will fall into the collecting barrel;

[0027] 2. A receiving groove is provided on the side wall at the end of the support tube, the upper port of the receiving groove is located on the inner side of the outer shell, and the lower port of the receiving groove is located above the conveying screw. Symmetrically distributed conveying screws are rotatably installed on both sides of the inner wall of the support tube, and the ends of the conveying screws are coaxially fixedly installed on the transmission gear. The driving gear of the second motor is meshed and installed on the top of the transmission gear. An inclined top discharge plate is fixedly connected to the opening in the middle of the support tube, so that the second motor can drive the transmission gear and the conveying screw to rotate. At this time, the conveying screw can drive the soil in the support tube to be discharged through the top discharge plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] How to use the soil film covering machine:

[0049] S1: The user connects the traction frame 4 with the external agricultural machinery to drive the overall movement of the device, places the mulch roller for covering on the mulch roller frame 3, pulls the end of the mulch film so that both sides of the mulch film can pass through the bottom of the guide wheel 30, and starts the first motor 5 and the second motor 20 at the same time. The output gear of the first motor 5 will drive the gear ring 7 and the transmission gear rod 9 to rotate synchronously, and the gear ring 7 drives the wheel ring 8 to rotate synchronously. The wheel ring 8 will roll on the land to provide auxiliary power. At the same time, the transmission gear rod 9 will drive the rotating frame 1201 to rotate synchronously, so that the collection bucket 1205 installed on the rotating frame 1201 rotates synchronously, so that the collection bucket 1205 can dig grooves on the land to take soil. Since the wheel ring 8 is always in contact with the ground and the size of the part of the collection bucket 1205 extending out of the wheel ring 8 is constant, the collection bucket 1205 can maintain a certain amount of collected soil to prevent the subsequent covering amount from being too small due to ground fluctuations;

[0050] S2: When the rotating frame 1201 drives the collecting bucket 1205 that has completed the soil collection to rotate to the top of the collecting barrel 13, the rotating frame 1201 will drive the force rod 1207 to move along the guide groove 11 through the limit ball 1206, so that the force rod 1207 can enter the straight inclined groove obliquely above the guide groove 11. At this time, the force rod 1207 will drive the limit ball 1206 away from the moving part 1203, so that the limit ball 1206 no longer conflicts with the moving part 1203 corresponding to the limit, and the soil in the collecting bucket 1205 will press against the connecting rod 1206 on the moving part 1203. The baffle 1204 applies pressure, and the baffle 1204 moves under the action of its own weight and soil pressure, so that the baffle 1204 no longer blocks the collection bucket 1205, and the soil in the collection bucket 1205 falls into the collection barrel 13. At the same time, the soil in the collection barrel 13 enters the housing 2 under the action of the inclined surface. When the force-bearing rod 1207 enters the arc groove obliquely below the guide groove 11 again, the force-bearing rod 1207 drives the limiting ball 1206 to move synchronously, so that the limiting ball 1206 pushes the baffle 1204 to reset through the moving member 1203;

[0051] S3: At the same time, the driving gear of the second motor 20 will drive the transmission gear 19 to rotate, and the transmission gear 19 will drive the two conveying screws 18 to rotate synchronously. The spiral grooves on the two conveying screws 18 rotate in opposite directions. The conveying screws 18 will drive the connecting plate 16 and the lifting plate 14 to rotate synchronously. At this time, the receiving groove 15 on the lifting plate 14 can collect the soil collected at the bottom of the shell 2, and the lifting plate 14 drives the soil to move synchronously, so that part of the soil in the receiving groove 15 can enter the connecting channel 17 first, and the remaining part of the soil in the receiving groove 15 will be discharged through the side discharge pipe 21 with a large opening. In this process, the conveying screw 18 will drive the soil in the connecting channel 17 to move along the inner wall of the support tube 1, and the soil in the support tube 1 will be discharged through the top discharge plate 32, thereby falling on the top of the external covering film, and the soil discharged from the side discharge pipe 21 will fall on both sides of the covering film;

[0052] S4: During the rotation of the lifting plate 14, the lifting plate 14 can push the force-bearing protrusion 22 to move, so that the force-bearing protrusion 22 will drive the transmission rod 23 to move synchronously. During this process, the thrust rod 24 on the other side of the transmission rod 23 will move along the outer tube 25 and the inclined groove on the lifting platform 26, so that the lifting platform 26 can move downward. The lifting platform 26 stretches the reset spring 27. At the same time, the lifting platform 26 drives the loading frame 28 installed at the bottom to move synchronously, so that the pressure wheel 29 on the loading frame 28 can compact the covered soil synchronously. When the lifting plate 14 no longer applies pressure to the force-bearing protrusion 22, the reset spring 27 can drive the lifting platform 26 to reset and move through the reset action.

9. The method for using a rice-wheat saline-alkali land soil film covering machine according to claim 1, characterized in that: How to use the soil film covering machine: S1: The user connects the traction frame (4) to an external agricultural machine to drive the overall movement of the device, places the ground film roller for covering on the film roller frame (3), pulls the end of the ground film so that both sides of the ground film can pass through the bottom of the guide wheel (30), and starts the first motor (5) and the second motor (20) at the same time. The output gear of the first motor (5) drives the gear ring (7) and the transmission gear rod (9) to rotate synchronously, and the gear ring (7) drives the wheel ring (8) to rotate synchronously. The wheel ring (8) will roll on the land to provide auxiliary power. At the same time, the transmission gear rod (9) will drive the rotating frame (1201) to rotate synchronously, so that the collection bucket (1205) installed on the rotating frame (1201) rotates synchronously, so that the collection bucket (1205) can open a groove on the land to take soil. Since the wheel ring (8) is always in contact with the ground, and the size of the part of the collection bucket (1205) extending out of the wheel ring (8) is constant, the collection bucket (1205) can maintain a certain amount of collected soil to prevent the subsequent covering amount from being too small due to the ups and downs of the ground; S2: When the rotating frame (1201) drives the collecting bucket (1205) to rotate to the top of the collecting barrel (13), the rotating frame (1201) drives the force rod (1207) to move along the guide groove (11) through the limiting ball (1206), so that the force rod (1207) can enter the straight inclined groove above the guide groove (11). At this time, the force rod (1207) drives the limiting ball (1206) away from the moving part (1203), so that the limiting ball (1206) no longer interferes with the moving part (1203) corresponding to the limiting position, and the soil in the collecting bucket (1205) will contact the connecting rod (1203) on the moving part (1203). The baffle (1204) connected thereto applies pressure, and the baffle (1204) moves under the action of its own weight and soil pressure, so that the baffle (1204) no longer blocks the collection bucket (1205), and the soil in the collection bucket (1205) falls into the collection barrel (13). At the same time, the soil in the collection barrel (13) enters the housing (2) under the action of the inclined surface, and when the force-bearing rod (1207) enters the arc groove obliquely below the guide groove (11) again, the force-bearing rod (1207) drives the limiting ball (1206) to move synchronously, so that the limiting ball (1206) pushes the baffle (1204) to reset through the moving member (1203); S3: At the same time, the driving gear of the second motor (20) drives the transmission gear (19) to rotate, and the transmission gear (19) drives the two conveying screws (18) to rotate synchronously. The spiral grooves on the two conveying screws (18) rotate in opposite directions. The conveying screws (18) drive the connecting plate (16) and the lifting plate (14) to rotate synchronously. At this time, the receiving groove (15) on the lifting plate (14) can collect the soil collected at the bottom of the shell (2), and the lifting plate (14) drives the soil to move synchronously, so that the receiving groove (15) can collect the soil collected at the bottom of the shell (2). Part of the soil in the groove (15) can first enter the connecting channel (17), and at the same time, the remaining part of the soil in the storage groove (15) will be discharged through the side discharge pipe (21) with a large opening. During this process, the conveying screw (18) will drive the soil in the connecting channel (17) to move along the inner wall of the support tube (1), and the soil in the support tube (1) will be discharged through the top discharge plate (32) and fall on the top of the external covering film. At the same time, the soil discharged from the side discharge pipe (21) will fall on both sides of the covering film. S4: During the rotation of the material lifting plate (14), the material lifting plate (14) can push the force-bearing protrusion (22) to move, so that the force-bearing protrusion (22) drives the transmission rod (23) to move synchronously. During this process, the thrust rod (24) on the other side of the transmission rod (23) moves along the outer tube (25) and the inclined groove on the lifting platform (26), so that the lifting platform (26) can move downward. The lifting platform (26) stretches the return spring (27). At the same time, the lifting platform (26) drives the loading frame (28) installed at the bottom to move synchronously, so that the pressure wheel (29) on the loading frame (28) can compact the covered soil synchronously. When the material lifting plate (14) no longer applies pressure to the force-bearing protrusion (22), the return spring (27) can drive the lifting platform (26) to return to its original position through the return action.
