Description

Technical Field

[0001] The present invention relates to the technical field of plant protection, in particular to agricultural film covering equipment for seedling cultivation based on bio-based materials. Background Art

[0002] In the agricultural production process of seedling cultivation, mulching operation is a key link. Mulching can not only effectively retain soil moisture and regulate soil temperature, but also inhibit weed growth, creating a good environment for the healthy growth of seedlings. However, traditional agricultural mulching equipment for seedling cultivation has exposed many problems in actual application, especially in the punching and post-punching cleaning links. When the punching device of the existing mulching equipment is working, the punching action often relies on manual operation, which not only leads to uneven punching quality and affects the planting effect of seedlings, but also makes it difficult to maintain a stable punching frequency. Unstable punching frequency will cause inconsistent planting spacing, affecting the uniformity of seedling distribution, and thus affecting the overall growth trend and final yield. In addition, there are also deficiencies in the cleaning of the punching equipment after punching. During the punching process, the punching equipment will bring out a large amount of soil and remain in the punching device. If not cleaned in time, the residual soil will gradually accumulate and block the punching equipment. For some manual equipment, the increased weight is not conducive to movement and the punching effect is also discounted. For some automated equipment, on the one hand, this will hinder the smooth progress of subsequent punching work and reduce work efficiency; on the other hand, serious blockage may damage the punching device, increase equipment maintenance costs and downtime, and traditional cleaning methods mostly rely on manual cleaning, which not only consumes a lot of manpower and time, but also cannot meet the needs of large-scale and high-efficiency agricultural production. Summary of the Invention

[0003] (1) Technical problems solved

At the same time, the setting of the rotating wheel enables the user to obtain holes punched at a fixed frequency, ensuring uniform planting spacing of seedlings, thereby improving planting efficiency. The cleaning device utilizes the characteristic of the magnetic sliding block being attracted by the magnetic counterweight plate to drive the pushing block to automatically clean the residual soil in the drilling tube.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] The outer wall of the second damping rod 3631 is fixedly connected to the inner wall of the rotating wheel 35, the outer wall of the roller 3634 is slidingly connected to the outer wall of the rotating wheel 35 through the movable groove 37, the outer wall of the roller 3634 is rollingly connected to the outer wall of the fixed cam 34, one end of the return spring 3632 is fixedly connected to the outer wall of the cross block 3633, and the other end of the return spring 3632 is fixedly connected to the inner wall of the rotating wheel 35. When the device moves as a whole, due to the setting of the magnetic counterweight plate 31, the positioning block 21 moves stably away from the pulling block 1. At the same time, the rotating wheel 35 rotates due to the friction with the membrane. When the rotating wheel 35 rotates, the roller 3634 rolls on the contour of the fixed cam 34. Since the contour shape of the fixed cam 34 is not a regular circle, the lower end of the fixed cam 34 is raised, so the roller 3634 will drive the cross block 3633 and the second damping rod 3631 to move up and down. Therefore, when the telescopic device 363 moves to the bottom end with the rotating wheel 35, the drilling tube 3635 will extend from the rotating wheel 35, thereby realizing the punching action of the drilling tube 3635.

[0034] Example 2: Please refer to Figure 1 、 Figure 2 、 Figure 6-10The present invention provides a technical solution: on the basis of embodiment 1, the limiting device 361 includes a connecting disk 3611, a limiting hole 3612 is opened in the wall of the connecting disk 3611, the outer wall of the connecting disk 3611 is fixedly connected with a fixing block 3613, the outer wall of the fixing block 3613 is slidably connected to the outer wall of the drilling tube 3635, and the side wall inside the drilling tube 3635 is slidably connected to the side wall of the connecting disk 3611. The limiting device 361 includes a connecting disk 3611, the limiting hole 3612 in the wall of the connecting disk 3611 and the fixing block 3613 on the outer wall cooperate with the drilling tube 3635 to limit the movement direction of the drilling tube 3635 and ensure the accuracy of drilling.

[0035] The cleaning device 362 includes a fixing bar 3621, the outer wall of the fixing bar 3621 is fixedly connected to the first damping rod 3622, the outer sleeve of the first damping rod 3622 is provided with a tension spring 3623, the end of the first damping rod 3622 away from the fixing bar 3621 is fixedly connected to the magnetic sliding block 3624, the outer wall of the magnetic sliding block 3624 is fixedly connected to the lifting plate 3625, and the outer wall of the lifting plate 3625 is fixedly connected to the pushing block 3626.

[0036] The outer wall of the fixing bar 3621 is fixedly connected to the side wall inside the rotating wheel 35, one end of the tension spring 3623 is fixedly connected to the outer wall of the fixing bar 3621, and the other end of the tension spring 3623 is slidably connected to the outer wall of the magnetic sliding block 3624. The side wall of the bottom of the pushing block 3626 is slidably connected to the side wall inside the connecting plate 3611 through the limiting hole 3612, and the side wall of the top of the pushing block 3626 is slidably connected to the side wall inside the drilling tube 3635. The outer wall of the magnetic sliding block 3624 is slidably connected to the outer wall of the drilling tube 3635. When the drilling tube 3635 is drilled, some soil is brought out of the ground and remains in the drilling tube 3635. At this time, when the cleaning device 362 in the rotating wheel 35 passes under the magnetic counterweight plate 31, Cleaning is carried out, wherein the pushing block 3626 slides on the inner side wall of the drilling tube 3635, and the magnetic sliding block 3624 slides on the outer wall of the drilling tube 3635. Therefore, when the magnetic sliding block 3624 is attracted by the magnetic counterweight plate 31 and moves, the magnetic counterweight plate 31 is pulled out of a part from the rotating wheel 35. At this time, the tension spring 3623 is stretched, and the magnetic sliding block 3624 drives the lifting plate 3625 and the pushing block 3626 to move outward. The pushing block 3626 is slidably connected to the inner side wall of the connecting plate 3611 through the limiting hole 3612, pushing part of the soil brought out from the inside of the drilling tube 3635. When the rotating wheel 35 continues to rotate, the pushed soil will fall out of the drilling tube 3635 under the action of inertia, centrifugal force and gravity.

[0037] Example 3: Please refer to Figure 1 - Figure 10The present invention provides a technical solution: Based on the first embodiment, the soil burying device 2 includes a positioning block 21, the outer wall of the positioning block 21 is symmetrically fixedly connected to a reciprocating device 22, the inner wall of the positioning block 21 is rotatably provided with a mounting shaft 23, the outer wall of the positioning block 21 is fixedly connected to a connecting frame 24, and the outer wall of the connecting frame 24 is fixedly connected to a guide device 25.

[0038] The outer wall of the connecting block 221 is fixedly connected to the outer wall of the positioning block 21, the end of the rotating rod 224 away from the elastic rod 223 is rotatably connected to the outer wall of the positioning block 21, the outer wall of the rotating rod 224 is slidably connected to the side wall inside the arc frame 222, the outer wall of the positioning block 21 is fixedly connected to the inner wall of the magnetic counterweight plate 31, the arc frame 222 is connected to the positioning block 21 through the connecting block 221, one end of the elastic rod 223 is fixed to the inner wall of the arc frame 222, and the other end is connected to the rotating rod 224, the bottom of the rotating rod 224 is connected to the connecting rod 225, the outer wall of the connecting rod 225 is connected to the rotating disk 226, and the outer wall of the rotating disk 226 is rotatably connected to the cone head runner 22 7. When the equipment moves forward, the cone head wheel 227 contacts the ground and rolls, and the cone head part will drill into the soil. At this time, due to the friction between the soil and the cone head wheel 227, the rotating disk 226 rotates. Due to the setting of the rotating disk 226, the cone head wheel 227 is set at the triangular position of the rotating disk 226. Therefore, the rotating disk 226 at this time bounces up and rotates due to the rotation radius setting. At this time, the rotating rod 224 will swing back and forth under the action of the elastic rod 223. This reciprocating swing drives the cone head wheel 227 not only to roll forward, but also to break up the soil surface passed by the reciprocating device 22.

[0039] Example 4: Please refer to Figure 1 - Figure 10The present invention provides a technical solution: on the basis of embodiment 1, the guiding device 25 includes an arc block 252, the outer wall of the arc block 252 is fixedly connected to the fixing frame 251, the outer wall of the arc block 252 is fixedly connected to the reinforcing rib 253, the side wall of the reinforcing rib 253 is fixedly connected to the connecting plate 254, the outer wall of the connecting plate 254 is provided with a guide groove 255, the outer wall of the connecting plate 254 is fixedly connected to the outer wall of the arc bar 256, the outer wall of the top of the arc block 252 is fixedly connected to the outer wall of the positioning block 21, the outer wall of the top of the reinforcing rib 253 is fixedly connected to the outer wall of the positioning block 21, and the guiding The arc block 252 of the device 25 is connected to the positioning block 21 through the fixing frame 251, and the reinforcing rib 253 enhances the structural stability. The arc block 252 keeps the guided covering film neat during the laying process, avoids wrinkles or offsets at the edge of the covering film, and improves the flatness and quality of the covering film. The lower end of the connecting plate 254 slides on the soil, and scoops the soil through the guide groove 255 during the sliding process. The scooped soil will be guided by the arc surface of the arc bar 256 after contacting the arc bar 256, so that the soil is pressed on the covered film, thereby preventing the film from being blown away by the wind after covering.

[0040] When in use, the agricultural film covering equipment for seedling cultivation based on bio-based materials realizes a series of operations such as agricultural film covering and punching through the coordinated work of the soil burying device 2, the rolling device 3 and other parts, thereby improving the efficiency of the film covering work during the seedling cultivation process;

The outer wall of the rotating disk 226 is rotatably connected to the cone head wheel 227. When the equipment moves forward, the cone head wheel 227 is connected to the ground The rotating disc 226 is rotated due to the friction between the soil and the cone-head rotating wheel 227. The cone-head rotating wheel 227 is arranged at the triangular position of the rotating disc 226. Therefore, the rotating disc 226 is set ...

[0043] The mounting shaft 23 rotating on the inner wall of the positioning block 21 is used to install the film roll, which is convenient for the film covering operation. The connecting frame 24 is fixed to the outer wall of the positioning block 21, and the guide device 25 on its outer wall plays the role of guiding and arranging the film. The arc block 252 of the guide device 25 is connected to the positioning block 21 through the fixing frame 251, and the reinforcing rib 253 enhances the structural stability. The arc block 252 keeps the guided film neat during the laying process, avoids wrinkles or offsets at the edge of the film, and improves the flatness and quality of the film. The lower end of the connecting plate 254 slides on the soil, and during the sliding process, the soil is scooped through the guide groove 255. The shoveled soil will be guided by the arc surface of the arc bar 256 after contacting the arc bar 256, so that the soil is pressed on the covered film, thereby preventing the film from being blown away by the wind after covering. By setting up the soil burying device 2 as a whole, the equipment can simultaneously pre-treat the farmland soil during the movement and ensure the smooth laying and arrangement of the film.

[0044] The rolling device 3 is fixed to the outer wall of the positioning block 21 of the burying device 2. The magnetic counterweight plate 31 makes the rolling device 3 more stable during operation through its own weight, preventing the device from shaking due to vibration and other reasons during movement, thereby affecting the working effect. The anti-slip plate 32 is symmetrically fixed to the bottom of the magnetic counterweight plate 31. The fixed shaft 33 is connected to the inner wall of the anti-slip plate 32.

[0045] The punching device 36 is installed on the inner wall of the rotating wheel 35, wherein the telescopic device 363 is telescopic in cooperation with the fixed cam 34 and the rotating wheel 35. The second damping rod 3631 is fixed to the inner wall of the rotating wheel 35, and a return spring 3632 is sleeved on the outside. The cross block 3633 is connected to the top of the second damping rod 3631. The roller 3634 is slidably connected to the outer wall of the rotating wheel 35 through the movable groove 37, and is rollingly connected to the outer wall of the fixed cam 34. When the device moves as a whole, due to the setting of the magnetic counterweight plate 31, the positioning block 21 is away from the part of the pulling block 1 Stable movement, at the same time, the rotating wheel 35 rotates due to the friction with the membrane. When the rotating wheel 35 rotates, the roller 3634 rolls on the contour of the fixed cam 34. Since the contour shape of the fixed cam 34 is not a regular circle, the lower end of the fixed cam 34 is raised, so the roller 3634 will drive the cross block 3633 and the second damping rod 3631 to move up and down. Therefore, when the telescopic device 363 moves to the bottom end with the rotating wheel 35, the drilling tube 3635 will extend from the rotating wheel 35, thereby realizing the drilling action of the drilling tube 3635;

[0046] The return spring 3632 stores elastic potential energy when the drilling tube 3635 extends and releases the energy when it retracts, thereby assisting the movement of the drilling tube 3635 and making the drilling action more stable. This design enables the drilling device 36 to drill holes in the covered soil at a fixed frequency during the movement of the device, facilitating the subsequent planting of seedlings and improving planting efficiency.

[0047] The limiting device 361 includes a connecting plate 3611. The limiting hole 3612 in the wall of the connecting plate 3611 and the fixing block 3613 on the outer wall cooperate with the drilling tube 3635 to limit the movement direction of the drilling tube 3635 and ensure accurate drilling.

[0048] The cleaning device 362 is used to clean the soil brought out by the drilling tube 3635 during the drilling process. The fixing bar 3621 is fixed to the inner side wall of the rotating wheel 35. One end of the first damping rod 3622 is connected to the fixing bar 3621, and a tension spring 3623 is sleeved on the outside. The other end is connected to the magnetic sliding block 3624. The outer wall of the magnetic sliding block 3624 is connected to the lifting plate 3625 and the pushing block 3626. When the drilling tube 3635 is drilled, some soil is brought out of the ground and remains in the drilling tube 3635. At this time, when the cleaning device 362 in the rotating wheel 35 passes under the magnetic counterweight plate 31, it will be cleaned. Since the pushing block 3626 slides on the inner side wall of the drilling tube 3635, the magnetic sliding block 362 The magnetic sliding block 3624 slides on the outer wall of the drilling tube 3635. Therefore, when the magnetic sliding block 3624 is attracted by the magnetic counterweight plate 31 and moves, the magnetic counterweight plate 31 is pulled out of a part of the rotating wheel 35. At this time, the tension spring 3623 is stretched, and the magnetic sliding block 3624 drives the lifting plate 3625 and the pushing block 3626 to move outward. The pushing block 3626 is slidably connected to the inner side wall of the connecting plate 3611 through the limiting hole 3612, pushing the part of the soil brought out of the drilling tube 3635. When the rotating wheel 35 continues to rotate, the dispersed soil will fall out of the drilling tube 3635 under the action of inertia, centrifugal force and gravity, ensuring that the interior of the drilling tube 3635 is unobstructed, thereby ensuring the smooth progress of subsequent drilling work.
