[0031] When in use, first hold the bogie 2, then control the driving part 4 to drive the electric wheel 3 to rotate, so that the electric wheel 3 drives the bogie 2 and the frame 1 to move, and at the same time, the manual work moves together with the bogie 2, and adjusts the moving direction by rotating the bogie 2, until the bogie 2 and the frame 1 move to the designated position for planting fruit trees, then control the driving part 4 to drive the electric wheel 3 to stop rotating, and then put the feeding shaft 101 with the film 102 wound around it into the notch of the limit plate 9, so that the feeding shaft 101 falls into the groove 1001 of the turntable 10, and then control the servo motor 1201 to drive the rotating shaft 11 and the turntable 10 to rotate through the pulley assembly 1202, until the next groove 1001 of the turntable 10 is aligned with the notch of the limit plate 9, and then repeat the above Operate until the loading shafts 101 with the film 102 wound around them are placed in the three grooves 1001 of the turntable 10, and the three loading shafts 101 are respectively located on the lower left side, lower right side and upper side of the rotating shaft 11, then pull out the leading end of the film 102 on the lower left loading shaft 101, and pass the leading end of the film 102 over the distance sensor 13, and then pass the leading end of the film 102 between the first hot melter 15 and the second hot melter 17, and then bypass under the guide roller 6 until the leading end of the film 102 comes between the film pressing wheel 5 and the guide roller 6, then put the leading end of the film 102 on the ground, and then put a stone in the top middle of the leading end of the film 102 to fix it, and then hold the bogie 2 again, and control the driving member 4 to drive again The electric wheel 3 rotates, so that the electric wheel 3 drives the bogie 2 and the frame 1 to move, and the manual labor moves together with the bogie 2, and adjusts the moving direction by rotating the bogie 2. As the bogie 2 and the frame 1 move in the fruit tree planting area, the head end of the film 102 is pressed on the ground. Therefore, the film 102 of the lower left feeding shaft 101 will be continuously unwound, so that the film 102 automatically covers the fruit tree planting area. At the same time, as the film pressing wheel 5 and the soil-moving plate 7 move with the frame 1, the film pressing wheel 5 will press on the top of the film 102 on the fruit tree planting area to compact the film 102 on the fruit tree planting area, and the soil-moving plate 7 will push the soil on the front and rear sides to the front and rear sides of the top of the film 102 to cover the fruit tree planting area. The film 102 on the planting ground is fixed. When the film 102 of the lower left feeding shaft 101 is used up during the film coating process, the tail end of the film 102 will gradually leave from above the distance sensor 13. When the distance sensor 13 senses that the distance between it and the film 102 is greater than the preset value, the distance sensor 13 will send a signal. After receiving the signal, the controller 8 will control the driving member 4 to drive the electric wheel 3 to stop rotating, so that the bogie 2 and the frame 1 stop moving. Then the controller 8 will control the second electric push rod 1801 to drive the suction cup 1802 to move to the left, so that the suction cup 1802 contacts the film 102 of the lower right feeding shaft 101. Then the controller 8 will control the vacuum pump 1803 to extract the air in the suction cup 1802 through the air pipe 1804.The suction cup 1802 sucks the film 102 on the lower right feeding shaft 101, and then the controller 8 controls the second electric push rod 1801 to drive the suction cup 1802 to move rightward and reset, so that the suction cup 1802 pulls the film 102 on the lower right feeding shaft 101 to the right, and then the controller 8 controls the first electric push rod 16 to drive the second hot fuser 17 to move downward, so that the second hot fuser 17 presses the film 102 on the lower right feeding shaft 101 downward, until the second hot fuser 17 presses the two rolls of film 102 (one roll is the film 102 on the lower left feeding shaft 101) and ... right feeding shaft 101) and the second hot fuser 17 presses the two rolls of film 102 (one The first film 102 and the other film 102 on the right lower side feeding shaft 101 are pressed on the first heat fuser 15, and then the controller 8 controls the first heat fuser 15 and the second heat fuser 17 to heat-fuse the two films 102 together, so that the two films 102 are connected together by heat-fusing. Then the controller 8 controls the first heat fuser 15 and the second heat fuser 17 to stop heat-fusing, and controls the first electric push rod 16 to drive the second heat fuser 17 to move upward and reset, and at the same time controls the vacuum pump 1803 to draw air into the suction cup 18 through the air pipe 1804. 02, so that the suction cup 1802 loosens the film 102 on the lower right feeding shaft 101, and then the controller controls the servo motor 1201 to drive the rotating shaft 11 and the turntable 10 to rotate clockwise through the pulley assembly 1202, until the lower right feeding shaft 101 is switched to the position of the lower left feeding shaft 101 through clockwise rotation, and the three feeding shafts 101 are mutually exchanged through clockwise rotation, and then the operator can take out the upper feeding shaft 101 from the groove 1001 of the turntable 10, and put the other feeding shaft 101 with the film 102 wound around it back The turning plate 10 is placed in the groove 1001, and then the bogie 2 is held again, and the driving member 4 is controlled to drive the electric wheel 3 to rotate again, so that the electric wheel 3 drives the bogie 2 and the frame 1 to continue to move, so that the film 102 can continue to be automatically covered on the fruit tree planting ground. After the film covering is completed on the fruit tree planting ground, the film 102 is cut off with a cutter, and then the lower left feeding shaft 101 is twisted to rotate, so that the excess film 102 is rewound back to the lower left feeding shaft 101, and finally the stone used to fix the film 102 is removed.

[0032] See also Figure 3 As shown, guide plates 19 are also included; two guide plates 19 are arranged on the top of the two limit plates 9, and the guide plates 19 are used to guide the feeding shaft 101 into the groove 1001 on the turntable 10.

[0033] By providing the guide plate 19 , the guide plate 19 can be used to guide the loading shaft 101 into the groove 1001 on the turntable 10 , thereby facilitating the operator to place the loading shaft 101 into the groove 1001 on the turntable 10 .

[0034] See also Figure 7As shown, the cutting mechanism includes a third electric push rod 20 and a cutter 21; the third electric push rod 20 is symmetrically arranged on the upper right side of the frame 1; the cutter 21 for cutting the film 102 is connected between the telescopic rods of the two third electric push rods 20.

[0035] By setting up a cutting mechanism, when it is necessary to use a knife to cut the film 102, the third electric push rod 20 can be controlled to drive the cutter 21 to move downward, so that the cutter 21 automatically cuts the film 102 on the fruit tree planting ground, and then the third electric push rod 20 is controlled to drive the cutter 21 to move upward and reset. In this way, it is convenient for the operator to cut the film 102 on the fruit tree planting ground.

[0037] When the front end of the film 102 comes between the film pressing wheel 5 and the guide roller 6, the front end of the film 102 needs to be directly below the fixing needle 27; when it is necessary to place a stone in the middle of the top of the front end of the film 102 for fixing, the fourth electric push rod 24 can be controlled to drive the lifting platform 23 to move downward, thereby driving the fifth electric push rod 25, the rotating rod 26 and the fixing needle 27 to move downward until the fixing needle 27 pierces the front end of the film 102 and enters the ground, so as to fix the front end of the film 102 on the ground with the fixing needle 27; then, as the bogie 2 and the frame 1 move, the extension and retraction of the fifth electric push rod 25 can be controlled at the same time. The retracting rod is extended, so that the rotating rod 26 and the fixed needle 27 stay in the specified position and do not move. After the film pressing wheel 5 is pressed on the front end of the film 102 and the soil-moving disc 7 pushes the soil onto the front end of the film 102, the fourth electric push rod 24 is controlled to drive the lifting platform 23 to move upward and reset, thereby driving the fifth electric push rod 25, the rotating rod 26 and the fixed needle 27 to move upward and reset, so that the fixed needle 27 is gradually separated from the ground and the front end of the film 102, and then the telescopic rod of the fifth electric push rod 25 is controlled to shorten and reset. In this way, the front end of the film 102 is fixed by the fixed needle 27, which is convenient for operation and does not require additional stone processing.

[0038] See also Figure 7 and Figure 8As shown, a guide roller 28 is also included; a guide roller 28 is rotatably provided on the left side of the bottom of the lifting platform 23, and the guide roller 28 is used to guide the film 102.

[0039] By providing the guide roller 28, when the front end of the film 102 passes through the bottom of the lifting platform 23, the guide roller 28 can not only guide the film 102, but also prevent the film 102 from being squeezed by the corner at the bottom of the lifting platform 23, so as to prevent the film 102 from being broken due to continuous friction at the corner at the bottom of the lifting platform 23.

[0040] See also Figure 8 and Fig. 9 As shown, it also includes a driving motor 29, a protective shell 30, a gear 31 and an arc-shaped rack 32; the driving motor 29 is installed on the telescopic rods of the two fifth electric push rods 25, and the protective shell 30 is rotatably set on the output shafts of the two driving motors 29, and the two protective shells 30 are rotatably connected to the front and rear ends of the rotating rod 26; the output shafts of the two driving motors 29 are connected to the gears 31, and the front and rear ends of the rotating rod 26 are connected to the arc-shaped rack 32, the gear 31 is meshed with the arc-shaped rack 32 on the same side, and the gear 31 and the arc-shaped rack 32 are both located in the protective shell 30 on the same side, and the protective shell 30 is used to protect the gear 31 and the arc-shaped rack 32.

[0041] When it is necessary to twist the lower left feeding shaft 101 to rotate so as to rewind the excess film 102 onto the lower left feeding shaft 101, the fourth electric push rod 24 can be controlled to drive the lifting platform 23 to move downward, thereby driving the fifth electric push rod 25, the rotating rod 26 and the fixed needle 27 to move downward until the fixed needle 27 pierces the cut end of the film 102 and enters the ground, and then the driving motor 29 is controlled to drive the gear 31 to rotate 120 degrees clockwise, so that the gear 31 drives the arc-shaped rack 32, the rotating rod 26 and the fixed needle 27 to rotate 120 degrees counterclockwise, so that the fixed needle 27 picks up the cut end of the film 102, and then the fourth electric push rod 24 is controlled to drive the lifting platform 23 to move downward, thereby driving the fifth electric push rod 25, the rotating rod 26 and the fixed needle 27 to move upward and reset, so that the fixed needle 27 drives the cut end of the film 102 to move upward, thereby separating the film 102 from the ground; when it is used next time, only It is necessary to control the fourth electric push rod 24 again to drive the lifting platform 23 to move downward, thereby driving the fifth electric push rod 25, the rotating rod 26 and the fixing needle 27 to move downward, so that the fixing needle 27 drives the cut end of the film 102 to move downward, so that the film 102 contacts the ground, and then the driving motor 29 drives the gear 31 to rotate counterclockwise by 120 degrees, so that the gear 31 drives the arc-shaped rack 32, the rotating rod 26 and the fixing needle 27 to rotate clockwise by 120 degrees, so that the fixing needle 27 pierces the cut end of the film 102 and enters the ground again; in this way, through the above-mentioned operation method, when the laminating work is finished, the cut end of the film 102 can be quickly and automatically picked up, so that the film 102 is not affected by the friction of the ground, and when it is used next time, the head end of the film 102 can be quickly and automatically positioned and fixed on the ground, so that the operator does not need to pull the head end of the film 102 again for positioning and fixing, which not only simplifies the operation but also saves time and effort.
