Description

Technical Field

[0001] This invention relates to the field of agricultural seedling technology, specifically to a film laying device for agricultural seedling cultivation. Background Technology

[0002] In large-scale agricultural seedling production, mulching is a core and fundamental process for regulating soil temperature and humidity in seedbeds, suppressing weed growth, and protecting seedling root development. Specialized mulch film laying devices for seedling cultivation, with their mechanized advantages, are widely used in greenhouses and open-air seedling bases, effectively replacing purely manual mulching work and becoming a commonly used agricultural machinery for improving the standardization of seedling operations. However, current mainstream traditional mulch film laying devices still suffer from insufficient automation. When existing equipment performs mulching operations, both the starting and ending positions require specialized manual assistance: at the start of the operation, workers need to manually dig a horizontal trench at the starting point of the seedbed and embed the end of the mulch film into the trench. The inside of the machine is covered with soil and compacted. The starting end of the mulch film is fixed by manual burying of the soil to prevent the end of the mulch film from loosening and being pulled up when the equipment is moving. When the whole machine travels to the end position of the seedbed operation, the mulch film roll still needs to be manually cut and separated, and the tail end of the mulch film is sealed with sealing materials to ensure the integrity and sealing of the entire mulch film. The cumbersome manual operation process at both ends directly interrupts the rhythm of continuous operation of the mulching machine, which to a certain extent damages the automation continuity of the equipment operation. This not only significantly reduces the overall efficiency of the mulching operation, but also adds labor links and labor input costs. Therefore, this invention provides a mulch film laying device for agricultural seedling cultivation. Summary of the Invention

[0003] The purpose of this invention is to provide an agricultural seedling mulch film laying device to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: an agricultural seedling mulch film laying device, comprising a main frame, two symmetrical horizontal plates fixedly installed on both sides of the end of the main frame, a hydraulic telescopic cylinder fixedly installed on the top of each of the two horizontal plates, an installation frame fixedly installed between the bottom telescopic ends of the two hydraulic telescopic cylinders, two symmetrical horizontal bars fixedly installed between the two side walls of the installation frame, a plurality of arc-shaped blocks fixedly installed between the two horizontal bars, an arc-shaped slide rail welded between the two side walls of each arc-shaped block, a movable block slidably arranged on each arc-shaped slide rail, a spring connected between each movable block and the side wall of the corresponding arc-shaped block, a support rod welded to the side wall of each movable block, and an arc-shaped shovel fixedly installed on the side of each support rod away from the corresponding movable block. This device relies on the linkage of multiple sets of arc-shaped shovels to achieve fully mechanized autonomous operation, replacing manual auxiliary processes, and no manual intervention is required for the entire process from start to finish.

[0005] Preferably, a drive motor is fixedly installed on the side wall of the mounting frame, and a transmission shaft is fixedly installed at the output end of the drive motor. The transmission shaft is rotatably connected between the two side walls of the mounting frame. Several annular water tanks are fixedly installed at equal intervals on the shaft body of the transmission shaft. When the drive motor operates, the drive motor drives the transmission shaft to rotate. The transmission shaft drives the annular water tanks, sleeves, limit rods, movable blocks, support rods, and several arc-shaped shovels to rotate synchronously. With the help of the synchronous rotation of several arc-shaped shovels, a transverse fixing groove is excavated at the starting point of the film covering. Subsequently, the hydraulic telescopic cylinder drives several arc-shaped shovels to move upward synchronously.

[0006] Preferably, a sleeve is fixedly installed on the side wall of each annular water tank, a limit rod is slidably provided in the inner cavity of each sleeve, a spring is connected between each limit rod and the inner cavity wall of the corresponding annular water tank, and a limit hole is opened on the side wall of each movable block to cooperate with the corresponding limit rod.

[0007] Preferably, a manifold is fixedly installed on the side wall of the mounting frame, and a plurality of infusion tubes are connected at equal intervals at the bottom of the manifold. An electric telescopic rod is fixedly installed on the side wall of the mounting frame, and a stopper plate is fixedly installed at the telescopic end of the electric telescopic rod, and the stopper plate is slidably disposed in the inner cavity of the manifold.

[0008] Preferably, each of the annular water tanks is rotatably connected to an annular plate on its sidewall, and each annular plate is connected to a second infusion pipe on its sidewall. During the mid-stage mulching operation, the electric telescopic rod moves the stopper plate towards the outside of the collecting pipe, allowing the liquid in the annular water tank to flow back into the collecting pipe sequentially through the second infusion pipe and the first infusion pipe. This causes the limiting rod at the designated position to disengage from the limiting groove and move into the annular water tank under the action of the second spring, thereby detaching the connection between the annular water tank and the arc-shaped shovel. Subsequently, the drive motor moves the annular water tank and the arc-shaped shovel, which are not disconnected, back and forth to realize the drilling operation during the mid-stage mulching operation, eliminating the need for manual film breaking in the later stage. In addition, different arc-shaped shovels can be flexibly switched to operate according to different seedling planting needs by changing the connection relationship between the first infusion pipe and the second infusion pipe, and the drilling spacing can be freely adjusted to adapt to the hole spacing requirements of various seedling planting modes.

[0009] Preferably, two symmetrical mounting plates are welded to the bottom of the main frame. Each mounting plate has a second electric telescopic rod fixedly mounted on its side wall. Each telescopic end of the second electric telescopic rod has an electric gripper fixedly mounted on it. Each gripper's clamping end is rotatably connected to an auxiliary wheel. The electric grippers drive the two auxiliary wheels on the same side to move towards each other, clamping and fixing the ends of the plastic film. Then, the second electric telescopic rod, through the electric grippers and auxiliary wheels, smoothly pulls the film head into the transverse groove. Subsequently, the arc-shaped shovel flips and reverses direction, and the soil material inside the shovel slides down naturally under gravity to fill the groove, automatically completing the backfilling of the film head. Then, the hydraulic telescopic cylinder drives the arc-shaped shovel downwards again, through... The curved shovel presses down to compact the soil, further reinforcing the anchoring effect and ensuring the initial end of the mulch film is securely fixed. When the tiller pulls this device to the end of the mulch film, the auxiliary rotating wheel re-clamps the mulch film on both sides to complete the positioning. Then, the drive motor drives the curved shovel to rotate 45 degrees. Subsequently, the hydraulic telescopic cylinder drives the rotated curved shovel to press down on one side to clamp the end of the mulch film, forming a limit fixation. Then, the drive motor drives the curved shovel to rotate back to its original position. Using the friction between the curved shovel and the mulch film, as well as between the bottom mold and the ground, the mulch film is torn and cut. After cutting, the curved shovel takes soil again to cover the mulch film, autonomously sealing and compacting the end of the mulch film. The entire process requires no manual intervention.

[0010] Preferably, the main frame has two symmetrical adjustable front wheels at its front end, an elastic roller clamping assembly at its top, a plastic film roller on the clamping end of the elastic roller clamping assembly, two symmetrical drive motors fixedly installed at the top of the main frame, a connecting rod at the output end of each drive motor, a pressure wheel on the side of each connecting rod away from the corresponding drive motor, and two symmetrical soil covering shovels at both ends of the rear of the main frame.

[0011] This invention provides an improved agricultural seedling mulch film laying device, which has the following improvements and advantages compared with the prior art: 1. This device relies on the linkage of multiple sets of arc-shaped shovels to achieve fully mechanized autonomous operation, replacing manual auxiliary processes: At the beginning of the operation, the movable arc-shaped shovels move synchronously and can automatically dig a horizontal fixing trench at the starting point of the seedbed. The auxiliary rotating wheel clamps the two sides of the mulch film and smoothly pulls the film head into the horizontal trench. Then the arc-shaped shovels flip and change direction, and the soil material in the shovels slides down naturally by gravity to fill the trench, automatically completing the backfilling of the film head. Then the downward pressing action of the arc-shaped shovels compacts the soil, further strengthening the anchoring effect and ensuring that the starting end of the mulch film is firmly fixed. 2. When the operation reaches the end position, the auxiliary wheel clamps the two sides of the mulch film again to complete the positioning. After the arc shovel flips to fix the angle, it presses down to clamp the end of the mulch film to form a limit fixation. The shovel body flips to complete the mulch film tearing and cutting operation simultaneously. After the cutting is completed, the arc shovel takes soil again to cover the soil and automatically seals the end of the mulch film by pressing and compacting it. No manual operation is required for the entire process from start to finish. 3. During the mid-stage mulching operation, designated arc-shaped shovels can be set up to form independent working units, and the synchronous punching of the mulch film can be completed in a coordinated manner, eliminating the need for manual film breaking in the later stage. Different arc-shaped shovels can also be flexibly switched to operate according to different seedling planting needs, and the punching spacing can be freely adjusted to adapt to the hole spacing requirements of various seedling modes.

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] This invention provides an improved agricultural seedling mulch film laying device. The technical solution of this invention is as follows: like Figures 1-10As shown, an agricultural seedling mulch film laying device includes a main frame 1. Two symmetrical adjustable front wheels 29 are provided at the front end of the main frame 1. An elastic roller clamping assembly 30 is provided at the top of the main frame 1, with a mulch film roller 31 placed on the clamping end of the elastic roller clamping assembly 30. Two symmetrical drive motors 32 are fixedly installed at the top of the main frame 1. Each drive motor 32 has a connecting rod 33 at its output end, and a pressure wheel 34 is provided on the side of each connecting rod 33 away from the corresponding drive motor 32. Two symmetrical soil-covering round shovels 35 are provided at both ends of the rear of the main frame 1. Two symmetrical horizontal plates 2 are fixedly installed on both sides of the ends of the main frame 1. A hydraulic telescopic cylinder 3 is fixedly installed on the top of each horizontal plate 2. An installation frame 4 is fixedly installed between the telescopic ends of the two hydraulic telescopic cylinders 3. Two symmetrical crossbars 5 are fixedly installed between the two side walls of the mounting frame 4. Several arc-shaped blocks 6 are fixedly installed between the two crossbars 5. Arc-shaped slide rails 7 are welded between the two side walls of each arc-shaped block 6. Movable blocks 8 are slidably installed on each arc-shaped slide rail 7. Springs 9 are connected between each movable block 8 and the side wall of the corresponding arc-shaped block 6. Support rods 10 are welded to the side wall of each movable block 8. Arc-shaped shovels 11 are fixedly installed on the side of each support rod 10 away from the corresponding movable block 8. In use, this device is fixed to the tail of the tiller. Then the tiller pulls this device to the starting point of the mulching. Then, the hydraulic telescopic cylinder 3 drives the mounting frame 4, arc-shaped blocks 6, movable blocks 8 and several arc-shaped shovels 11 to move down synchronously, so that one side of each arc-shaped shovel 11 contacts the ground.

[0016] Furthermore, a drive motor 12 is fixedly installed on the side wall of the mounting frame 4. A transmission shaft 13 is fixedly installed at the output end of the drive motor 12, and the transmission shaft 13 is rotatably connected between the two side walls of the mounting frame 4. Several annular water tanks 14 are fixedly installed at equal intervals on the shaft of the transmission shaft 13. When the drive motor 12 operates, it drives the transmission shaft 13 to rotate, which in turn drives the annular water tanks 14, sleeves 15, limit rods 16, movable blocks 8, support rods 10, and several arc-shaped shovels 11 to rotate synchronously. A series of curved shovels 11 are used to excavate a transverse fixing trench at the starting point of the film covering operation, with the synchronous flipping operation of the shovels 11. Then, a hydraulic telescopic cylinder 3 drives the curved shovels 11 to move upwards synchronously. Two symmetrical mounting plates 25 are welded to the bottom of the main frame 1. Each mounting plate 25 has an electric telescopic rod 26 fixedly mounted on its side wall. Each electric telescopic rod 26 has an electric gripper 27 fixedly mounted at its telescopic end. Each electric gripper 27 has an auxiliary rotating wheel 28 rotatably connected to its gripping end. The electric grippers 27 drive the two auxiliary rotating wheels 28 on the same side to move towards each other, completing the process. The plastic film is clamped and fixed at both ends. Then, the electric telescopic rod 2, through the electric gripper 27 and auxiliary rotating wheel 28, smoothly pulls the film head into the transverse groove. Subsequently, the arc-shaped shovel 11 flips and changes direction, and the soil material in the shovel slides down naturally under gravity to fill the groove, automatically completing the backfilling of the film head. Then, the hydraulic telescopic cylinder 3 drives the arc-shaped shovel 11 to move down again, and the downward action of the arc-shaped shovel 11 compacts the soil, further strengthening the anchoring effect and ensuring that the starting end of the plastic film is firmly fixed. When the soil turner pulls this device to the end of the film covering, the auxiliary rotating wheel 28 resets. Positioning is achieved by clamping the plastic film on both sides. Then, the drive motor 12 drives the arc-shaped shovel 11 to rotate 45 degrees. Subsequently, the hydraulic telescopic cylinder 3 drives the rotated arc-shaped shovel 11 to press down on one side to clamp the end of the plastic film and form a limit fixation. Then, the drive motor 12 drives the arc-shaped shovel 11 to rotate and reset. The friction between the arc-shaped shovel 11 and the plastic film, as well as between the bottom mold and the ground, is used to tear and cut the plastic film. After cutting, the arc-shaped shovel 11 takes soil again to cover the plastic film and automatically seals the end of the plastic film by compacting and sealing it. The entire process does not require manual operation.

[0017] Furthermore, a sleeve 15 is fixedly installed on the side wall of each annular water tank 14, and a limit rod 16 is slidably provided in the inner cavity of each sleeve 15. A spring 17 is connected between each limit rod 16 and the inner cavity wall of the corresponding annular water tank 14. A limit hole 18 is opened on the side wall of each movable block 8 to cooperate with the corresponding limit rod 16. A collection pipe 19 is fixedly installed on the side wall of the mounting frame 4. Several infusion tubes 20 are connected at equal intervals at the bottom of the collection pipe 19. An electric telescopic rod 21 is fixedly installed on the side wall of the mounting frame 4. A stopper plate 22 is fixedly installed at the telescopic end of the electric telescopic rod 21, and the stopper plate 22 slides. An annular plate 23 is rotatably connected to the side wall of each annular water tank 14, which is located inside the cavity of the manifold 19. Each annular plate 23 is connected to the side wall of the manifold 24. During the mid-section film covering operation, the electric telescopic rod 21 drives the stopper plate 22 to move towards the outside of the manifold 19, so that the liquid in the annular water tank 14 flows back to the inside of the manifold 19 through the second infusion pipe 24 and the first infusion pipe 20 in sequence. This causes the limiting rod 16 at the designated position to move away from the limiting groove and into the annular water tank 14 under the action of the second spring 17, thereby detaching the connection between the annular water tank 14 and the arc-shaped shovel 11. Subsequently, the drive motor 12 drives the still connected annular water tank 14 and arc-shaped shovel 11 to move back and forth, realizing the drilling operation during the middle stage of film covering, eliminating the need for manual film breaking in the later stage; in addition, according to different seedling planting needs, different arc-shaped shovels 11 can be flexibly switched to operate by changing the connection relationship between infusion pipe 1 20 and infusion pipe 24, and the drilling spacing can be freely adjusted to adapt to the hole spacing requirements of various seedling planting modes.

[0018] Working principle: In use, this device is fixed to the tail of the tiller; then the tiller pulls this device to the starting point of the mulching; subsequently, the hydraulic telescopic cylinder 3 drives the mounting frame 4, the arc-shaped block 6, the movable block 8, and several arc-shaped shovels 11 to move down synchronously, so that one side of each arc-shaped shovel 11 contacts the ground; then the drive motor 12 operates, driving the transmission shaft 13 to rotate, which in turn drives the annular water tank 14, the sleeve 15, the limit rod 16, the movable block 8, the support rod 10, and the several arc-shaped shovels 11 to rotate synchronously, thus achieving the desired effect. The first step involves excavating a transverse fixing trench at the starting point of the mulch film. Then, a hydraulic telescopic cylinder 3 drives several curved shovels 11 to move upwards simultaneously. Next, an electric gripper 27 drives two auxiliary rotating wheels 28 on the same side to move towards each other, clamping and fixing the ends of the mulch film. Then, an electric telescopic rod 2, through the electric gripper 27 and auxiliary rotating wheels 28, smoothly pulls the mulch film head into the transverse trench. The curved shovels 11 then flip and change direction, allowing the mulch material inside to slide down naturally under gravity and fill the trench, automatically completing the mulch film head backfilling. Finally, the hydraulic telescopic cylinder 3 drives the curved shovels 11 downwards again, compacting the mulch material through the downward pressing action of the curved shovels 11. To further reinforce the anchoring effect and ensure the initial end of the mulch film is securely fixed, the electric gripper 27 releases the auxiliary rotating wheel 28 from the mulch film and resets under the action of the electric telescopic rod 26. Then, the drive motor 32 drives the connecting rod 33 and the edge pressing wheel 34 to rotate, causing the edge pressing wheel 34 to abut against the top of the left and right ends of the mulch film. The tiller then moves this device, and the mulch film is laid on the seedbed sequentially through the auxiliary rotating wheel 28 and the edge pressing wheel 34. Simultaneously, the covering shovel 35 turns up the soil on both sides of the seedbed and covers the left and right sides of the mulch film, thus performing automatic edge sealing. Once the tiller pulls this... When the device moves to the end of the film covering, the auxiliary rotating wheel 28 is re-clamped on both sides of the film to complete the positioning. Then, the drive motor 12 drives the arc-shaped shovel 11 to rotate 45 degrees. Then, the hydraulic telescopic cylinder 3 drives the rotated arc-shaped shovel 11 to press down on one side to clamp the end of the film to form a limit fixation. Then, the drive motor 12 drives the arc-shaped shovel 11 to rotate and reset. With the friction between the one side of the arc-shaped shovel 11 and the film and between the bottom mold and the ground, the film is torn and cut. After the cutting is completed, the arc-shaped shovel 11 takes soil again to cover the film and automatically seals the end of the film by compacting and sealing it. The entire process from start to finish does not require manual operation. During the mid-stage mulching operation, the electric telescopic rod 21 moves the stopper plate 22 towards the outside of the collection pipe 19, causing the liquid in the annular water tank 14 to flow back into the collection pipe 19 through the infusion pipe 24 and the infusion pipe 20. This causes the limiting rod 16 at the designated position to move away from the limiting groove and into the annular water tank 14 under the action of the spring 2 17, thereby detaching the connection between the annular water tank 14 and the arc-shaped shovel 11. Subsequently, the drive motor 12 drives the annular water tank 14 and the arc-shaped shovel 11, which are still connected, to move back and forth, realizing the drilling operation during the mid-stage mulching operation, eliminating the need for manual film breaking in the later stage. In addition, according to different seedling planting needs, different arc-shaped shovels 11 can be flexibly switched to operate by changing the connection relationship between the infusion pipe 20 and the infusion pipe 24, and the drilling spacing can be freely adjusted to adapt to the hole spacing requirements of various seedling planting modes.
