Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a plastic film covering device for angelica planting. Background Technology

[0002] Existing plastic film covering devices for angelica cultivation have technical defects. When adjusting the spacing, the device spacing is fixed or requires manual adjustment of the film covering structure on both sides. At the same time, the power adaptability is insufficient, mostly supporting only manual or agricultural machinery traction. The compatibility with small complex plots and large contiguous plots is insufficient.

[0003] Therefore, this utility model provides a plastic film covering device for angelica planting. By cooperating with the adjusting rod and the threaded rod with reverse threads at both ends, the distance of the L-shaped frame on both sides can be adjusted synchronously to adapt to different row spacings. It is equipped with a drag rod for manual traction and a connecting rod to connect with agricultural machinery to meet the power needs of different operating scenarios. The combined design of the front plow head aligning the bed, the film pressing wheel pressing the film, and the rear plow head returning and fixing the soil is conducive to the plastic film adhering to the soil, meeting the needs of the agricultural machinery industry for plastic film covering devices for angelica planting with adjustable film spacing. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a mulch film covering device for Angelica sinensis planting, comprising: an adjusting rod, symmetrically arranged film covering devices on both sides of the adjusting rod, a front plow head on each film covering device, and a rear plow head on the side of each film covering device away from the front plow head; the film covering device includes an L-frame, a threaded rod fixedly connected to the inner wall of the top of the L-frame, a connecting rod fixedly connected to the outer wall of the L-frame near the threaded rod, guide legs and pressing legs fixedly connected to the outer wall of the L-frame respectively, a rear plow leg fixedly connected to the outer wall of the L-frame away from the guide legs, a guide rod fixedly connected to the bottom end of the guide legs, a pressing wheel rotatably connected to the inner wall of the bottom end of the pressing leg, and a moving wheel rotatably connected to the outer wall of the bottom end of the rear plow leg and the inner wall of the L-frame respectively; the outer wall of the smooth part of the threaded rod... The device is rotatably connected to a drag rod, and the inner wall of the guide leg is threadedly connected to a loading and unloading rod. The loading and unloading rod is paired with a loading rod. Before carrying out the mulching operation for Angelica sinensis planting, the device needs to be pre-adjusted and the mulch film needs to be loaded to lay the foundation for subsequent operations. First, the row spacing is adjusted. Since the threaded connection direction of the two ends of the adjustment rod is opposite to that of the threaded rod, the operator can rotate the adjustment rod clockwise or counterclockwise to drive the L-frames symmetrically set on both sides to move closer or further away synchronously until the spacing of the mulching devices on both sides matches the preset row spacing for Angelica sinensis planting, ensuring that the subsequent mulching can cover the planting area. Then, the mulch film roll is loaded. First, the loading and unloading rod connected to the inner wall of the guide leg is rotated and disassembled. The center hole of the rolled mulch film is aligned with the loading rod and installed. Then, the loading and unloading rod is connected to the loading rod and rotated in the opposite direction to lock it, so that the mulch film roll is stably fixed between the two rods.

[0005] Preferably, the inner wall of the adjusting rod is threadedly connected to the inner wall of the threaded rod, the outer wall of the loading rod is fixedly connected to the inner wall of the L-frame on the other side of the adjusting rod, the outer wall of the L-frame away from the rear plow leg is fixedly connected to the outer wall of the front plow head by bolts, and the outer wall of the rear plow head is fixedly connected to the outer wall of the rear plow leg. After the initial preparation of the device is completed, a suitable power connection method needs to be selected according to the planting area and operation requirements to achieve stable traction of the device. If it is a small area of ​​angelica planting or a complex terrain area, manual pulling can be used to provide power. When the operator holds the drag bar and applies a uniform pulling force, the motion wheels at the bottom of the L-frame and the bottom of the rear plow leg roll accordingly, reducing the frictional resistance between the device and the ground and reducing the jamming during the traction process. If it is a large area of ​​contiguous angelica planting, the agricultural machinery pulling can be selected to provide power. The special connecting device on the agricultural machinery is connected to the connecting rod fixed to the outer wall of the L-frame and locked by bolts or buckle structure to prevent the connection from falling off during operation. The device is driven forward by the traction force of the agricultural machinery.

[0006] Preferably, the front plow head is inside the rear plow head. The adjusting rod is used to adjust the spacing of the L-frame, and the threaded rods at both ends of the adjusting rod are threaded in opposite directions. The loading and unloading rod, in conjunction with the loading rod, is used to load the mulch film roll. The pressing wheel is used to press the mulch film to make it contact the planting soil. After the initial preparation of the device is completed, a suitable power connection method needs to be selected according to the planting area and operation requirements to achieve stable traction of the device. If it is a small area of ​​angelica planting or a complex terrain area, manual pulling can be used to provide power. When the operator holds the drag bar and applies a uniform pulling force, the motion wheel at the bottom of the L-frame and the bottom of the rear plow leg rolls accordingly, reducing the frictional resistance between the device and the ground and reducing the jamming during the traction process. If it is a large area of ​​contiguous angelica planting, the agricultural machinery can be selected to provide power. The special connecting device on the agricultural machinery is connected to the connecting rod fixed on the outer wall of the L-frame and locked with bolts or buckles to prevent the connection from falling off during operation. The device is driven forward by the traction force of the agricultural machinery.

[0007] Preferably, the outer wall of the front plow head contacts the planting ground to turn over the planting soil, and the outer wall of the rear plow head contacts the planting soil to gather the planting soil and press it down to cover the mulch film. After the mulch film is smoothly guided and unfolded, the device enters the final stage of the mulching operation, pressing the film to adhere to the soil and fixing it in place, thus completing the entire mulching process. The film pressing wheel, which is rotatably connected to the inner wall of the bottom of the film pressing leg, rolls continuously as the device moves forward and applies uniform pressure to the unfolded film, pressing the film onto the surface of the planting bed, making the film adhere to the soil, eliminating gaps between the film and the soil, and preventing local bulging of the film due to poor adhesion. Subsequently, the outer rear plow head contacts the planting soil, and its unique arc-shaped structure moves with the device to gather the soil on both sides of the planting bed towards the middle, pressing the edge of the mulch film under the soil to form a stable fixed structure. This helps to resist the influence of external factors such as wind on the film, prevents the mulch film from being blown up or displaced, and helps the mulch film to play a stable role in the long term, providing a good growing environment for angelica planting.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model, by setting an adjusting rod, utilizes its cooperation with the threaded rod with reverse threads to achieve synchronous spacing adjustment without separately adjusting the structures on both sides, adapting to different row spacing requirements for Angelica sinensis planting. It also supports two methods: manual dragging with a drag bar and dragging with a connecting rod of agricultural machinery, taking into account both small-area and large-area contiguous plot operations, which is conducive to broadening the applicable scenarios.

[0009] 2. By setting loading and unloading rods and loading rods, this utility model simplifies the process of disassembling and assembling the mulch film. The guide rod helps to avoid the risk of the film being cut by the pressing structure, which is beneficial to the integrity of the film. The continuous operation of the front plow head aligning the bed, the pressing wheel pressing the film, and the rear plow head backfilling and fixing the soil allows the mulch film to adhere to the soil, avoiding hollowing and displacement, which is conducive to the long-term stable performance of the mulch film in terms of heat preservation and moisture retention.

A rear plow leg 108 is fixedly connected to the outer wall of the L-frame 101 on the side away from the guide leg 106. A guide rod 112 is fixedly connected to the bottom end of the guide leg 106. A pressing wheel 109 is rotatably connected to the inner wall of the bottom end of the pressing leg 107. A motion wheel 110 is rotatably connected to the outer wall of the bottom end of the rear plow leg 108 and the inner wall of the L-frame 101, respectively. A drag rod 103 is rotatably connected to the outer wall of the smooth part of the threaded rod 102. A loading and unloading rod 105 is threadedly connected to the inner wall of the top end of the guide leg 106. A loading rod 104 is used in conjunction with the loading and unloading rod 105.

[0014] The inner wall of the adjusting rod 2 is threadedly connected to the inner wall of the threaded rod 102. The outer wall of the loading rod 104 is fixedly connected to the inner wall of the L frame 101 on the other side of the adjusting rod 2. The outer wall of the L frame 101 at the end away from the rear plow leg 108 is fixedly connected to the outer wall of the front plow head 3 by bolts. The outer wall of the rear plow head 4 is fixedly connected to the outer wall of the rear plow leg 108.

[0015] The front plow head 3 is inside the rear plow head 4. The adjusting rod 2 is used to adjust the spacing of the L frame 101. The threaded rods 102 connected to both ends of the adjusting rod 2 have opposite thread directions. The loading and unloading rod 105 cooperates with the loading rod 104 to load the mulch film roll. The pressing roller 109 is used to press the mulch film to make it contact the planting soil.

[0016] The outer wall of the front plow head 3 contacts the planting ground and is used to turn over the planting soil, while the outer wall of the rear plow head 4 contacts the planting soil and is used to gather the planting soil back and press it down to cover the ground with mulch.

[0017] Working principle: Before carrying out the mulching operation for Angelica sinensis planting, the preliminary adjustment of the equipment and the loading of the mulch film must be completed to lay the foundation for subsequent operations. First, the row spacing is adjusted. Since the threaded connection direction of the two ends of the adjusting rod 2 and the threaded rod 102 is opposite, the operator can rotate the adjusting rod 2 clockwise or counterclockwise to drive the L-frames 101 set on both sides to move closer or further away synchronously until the spacing of the mulching devices 1 on both sides matches the preset row spacing for Angelica sinensis planting, ensuring that the subsequent mulching can cover the planting area. Next, the mulch film roll is loaded. First, rotate and disassemble the loading and unloading rod 105 connected to the inner wall of the top of the guide leg 106. Align the center hole of the rolled mulch film with the loading rod 104 and install it. Then, connect the loading and unloading rod 105 with the loading rod 104 and rotate it in the opposite direction to lock it, so that the mulch film roll is stably fixed between the two rods.

[0018] After the initial preparation of the device is completed, a suitable power connection method should be selected according to the planting area and operation requirements to achieve stable traction of the device. If it is a small area of ​​angelica planting or a complex terrain area, manual pulling can be used to provide power. When the operator holds the drag bar 103 and applies a uniform pulling force, the motion wheel 110 at the bottom of the L frame 101 and the bottom of the rear plow leg 108 will roll accordingly, reducing the frictional resistance between the device and the ground and reducing the jamming during the traction process. If it is a large area of ​​contiguous angelica planting, agricultural machinery should be selected to provide power. The special connecting device on the agricultural machinery is connected to the connecting rod 111 fixed on the outer wall of the L frame 101 and locked with bolts or buckles to prevent the connection from falling off during operation. The device is moved forward with the help of the traction force of the agricultural machinery.

[0020] After the mulch film is successfully guided and unfolded, the device enters the final stage of the mulching operation, pressing the film to adhere to the soil and fixing it in place, thus completing the entire mulching process. The pressing wheel 109, which is rotatably connected to the inner wall of the bottom of the pressing leg 107, rolls continuously as the device moves forward and applies uniform pressure to the unfolded film, pressing the film onto the surface of the planting bed, making the film adhere to the soil, eliminating gaps between the film and the soil, and preventing local bulging of the film due to poor adhesion. Subsequently, the outer rear plow head 4 comes into contact with the planting soil. Its unique arc structure moves with the device, bringing the soil on both sides of the planting bed back to the middle, pressing the edge of the mulch film under the soil, forming a stable fixed structure. This helps resist the influence of external factors such as wind on the film, preventing the mulch film from being blown up or shifted, and ensuring that the mulch film can play a stable role in the long term, providing a good growing environment for angelica planting.
