Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment technology, and in particular relates to a film-covered seeder. Background Technology

[0002] Currently, the film-pressing device of roller seeders mainly uses a single-function film-pressing wheel. While pressing the film, the film-pressing wheel also exerts a pushing force on the film, causing it to misalign. The seeding rollers mostly roll independently and naturally. This structure makes the rollers prone to dragging and slipping when sowing in different soil types. Firstly, this causes the seeds planted in the soil to shift from the opening of the seed hole in the film. After germination, the seeds may burrow into the film and fail to emerge properly. Secondly, it results in inconsistent plant spacing and prevents precise covering of individual seed holes. Instead, the seed holes are covered with soil along a single line on the film. This technique not only occupies most of the film's light-receiving area but also results in uneven soil coverage, significantly affecting seed germination. In daily planting, two methods are commonly used: one is to dig holes, place seeds, cover with soil, and then cover with film; the other is to cover with film first, then break the film, and then dig holes to place seeds. Therefore, regardless of the method, the planting process involves many steps, which is time-consuming and labor-intensive.

[0003] Therefore, a seeder is needed that can accurately dig holes, release seeds, cover the soil, and press down the opening to prevent moisture evaporation. Summary of the Invention

Detailed Implementation

[0026] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] Please refer to Figures 1 to 4 A film-covered seeder includes a transport mechanism 10, a sowing and soil application mechanism 20, a soil transport mechanism 30, and a perforation and film-breaking mechanism 40. The sowing and soil application mechanism 20, the soil transport mechanism 30, and the perforation and film-breaking mechanism 40 are sequentially arranged on the transport mechanism 10, and the transport mechanism 10 can drive the sowing and soil application mechanism 20 and the soil transport mechanism 30 to move.

[0028] The sowing and soil application mechanism 20 includes a transmission component 201, a seed box 202, a soil covering box 203, and an engagement component 204. The transmission component 201 is used to connect the transport mechanism 10 and the engagement component 204. The engagement component 204 is disposed on the side wall of the seed box 202 and the soil covering box 203, and an outlet 2031 is provided on the lower end face of the seed box 202 and the soil covering box 203.

[0029] The perforation and membrane breaking mechanism 40 includes a movable component 401 and a membrane breaking component 402. The movable component 401 can drive the membrane breaking component 402 to move, and the outlet of the membrane breaking component 402 is located above the soil transport mechanism 30.

[0030] The transport mechanism 10 drives the sowing and soil application mechanism 20, the soil transport mechanism 30, and the perforation and film-breaking mechanism 40. During operation, after traveling a certain distance, the transport mechanism 10 stops, and the movable component 401 drives the film-breaking component 402 downwards. The film-breaking component 402 first breaks the film, and then, as it continues downwards, it begins to dig a hole. The excavated soil remains inside the film-breaking component 402. Then, under the action of the movable component 401, the film-breaking component 402 first... The membrane-breaking component 402 moves upward, and when it reaches the top of the movable component 401, it moves horizontally, and at the same time, the transport mechanism 10 begins to move forward. Simultaneously, the soil inside the membrane-breaking component 402 falls onto the soil-carrying mechanism 30 under the pressure of the movable component 401. Under the operation of the soil-carrying mechanism 30, the soil falls into the covering box 203, which contains some soil beforehand. The soil-carrying mechanism 30 is configured as follows: When the soil-carrying mechanism 30 is installed, a hole is made in the transport mechanism 10. One end of the soil-carrying mechanism 30 is positioned above the transport mechanism 10, and the other end is positioned below the transport mechanism 10 through the hole. At this time, the soil-carrying mechanism 30 is inclined on the transport mechanism 10. In specific use, the soil-carrying mechanism 30 can be set as a conveyor belt. When the soil-carrying mechanism 30 is installed, the relevant personnel can choose the specific power source according to the existing technology. When the transport mechanism 10 moves again, the transmission component 201 is connected to the transport mechanism 10 to drive the rotation of the meshing component 204. When sowing and covering with soil, the seeds in the seed box 202 are first sown from the outlet 2031. Then, the soil in the covering box 203 is used to cover the sown seeds from the outlet 2031. Under the action of the film-covered seeder, the precise film breaking and hole digging, seed release, and finally covering with soil are completed, improving the planting efficiency and pressing down the opening to prevent water evaporation.

[0031] Furthermore, the transport mechanism 10 includes a plurality of drive wheels 101, a drive shaft 102 and a frame plate 103. The drive wheels 101 are rotatably connected to the drive shaft 102, and the drive shaft 102 is disposed at the lower end of the frame plate 103.

[0032] The two ends of the drive shaft 102 are connected to the power wheel 101, and the drive shaft 102 is located on the lower end face of the frame plate 103. The specific shape is the same as that of the vehicle's tires, chassis and drive shaft 102, and the function is the same. In this case, the transport mechanism 10 is also used to drive the operation of the sowing and soil application mechanism 20 and the perforation and film breaking mechanism 40. When setting the installation position of the transport mechanism 10, this installation method is a conventional operation.

[0033] In one specific implementation, the soil transport mechanism 30 is a conveyor belt, and one end of the soil transport mechanism 30 is located above the soil covering box 203, and the other end is located below the perforation and membrane breaking mechanism 40.

[0034] During use, the soil inside the membrane breaking component 402 falls onto the soil conveying mechanism 30. As the soil conveying mechanism 30 operates, the soil falls into the covering box 203. The soil conveying mechanism 30 is configured such that one end is below the transport mechanism 10 and the other end is above the covering box 203. The soil conveying mechanism 30 is tilted onto the transport mechanism 10. In specific applications, the soil conveying mechanism 30 can be configured as a conveyor belt. When configuring the mechanism, the relevant personnel can select the appropriate power source based on existing technology. To prevent soil from falling off the soil conveying mechanism 30, which operates in a slow uphill process, an interceptor can be installed on the mechanism. This interceptor prevents soil from falling off the soil conveying mechanism 30 during operation.

[0035] Specifically, the meshing assembly 204 includes a driving wheel 2041 and a driven wheel 2042. The driving wheel 2041 is disposed on the side wall of the seed box 202, and the driven wheel is disposed on the side wall of the soil covering box 203. The driving wheel 2041 and the driven wheel are meshed together.

[0036] The power source for the meshing assembly 204 comes from the drive shaft 102. It rotates as the drive shaft 102 rotates, and the drive shaft 102 is connected to the driving wheel 2041 by a belt. The belt drives the meshing assembly 204 to rotate, and at the same time, the drive assembly 201, the drive shaft 102 and the meshing assembly 204 can rotate synchronously. Then, the driving wheel 2041 and the driven wheel 2042 are two meshing gears. When the driving wheel 2041 rotates, it drives the driven wheel to rotate, which saves the parts required for installation and improves the fit between the parts.

[0037] In a preferred embodiment, the sowing and soil application mechanism 20 further includes a seed wheel 205 and a soil covering wheel 206. The seed wheel 205 is disposed inside the seed box 202 and is fixedly connected to the driving wheel 2041. The soil covering wheel 206 is disposed inside the soil covering box 203 and is connected to the driven wheel.

[0038] The seed wheel 205 is installed inside the seed box 202 and is fixedly connected to the driving wheel 2041. In order to drive the seed wheel 205 to rotate, the covering wheel 206 is installed inside the covering box 203 and is connected to the driven wheel, so that the covering wheel 206 can rotate. During sowing, the seed wheel 205 sows the seeds into the soil from the outlet 2031 while rotating. Then, the covering wheel 206 covers the sown seeds with soil from the outlet 2031 on the covering box 203, thus completing the series of operations of sowing and covering.

[0039] In a preferred embodiment, the seed wheel 205 is provided with a seed groove 2051, and the covering wheel 206 is provided with a covering groove 2061;

[0040] In the first position, the seed trough 2051 is connected to the outlet 2031, and the covering trough 2061 is not connected to the outlet 2031;

[0041] In the second position, the seed trough 2051 is not connected to the outlet 2031, and the covering trough 2061 is connected to the outlet 2031.

[0042] When performing sowing and covering operations, the seeds need to be sown in the soil first, and then covered with soil. Therefore, when setting the seed trough 2051 and the covering trough 2061, a certain angle should be set between them, generally 90º is best. When setting them, the seed trough 2051 should be smaller to avoid multiple seeds falling, and the covering trough 2061 should be larger to ensure that the soil can cover the sown seeds. At the same time, when the seed wheel 205 and the covering wheel 206 are running, the seed trough 2051 on the seed wheel 205 first aligns with the outlet 2031 to drop the seeds into the pit. Then the covering trough 2061 aligns with the outlet to cover the seeds with soil. The advantage of this setting is that sowing is performed first, and then covering is performed, avoiding the situation where the seeds are not covered after being sown.

[0043] In another preferred embodiment, the movable component 401 includes a motor 4011, a fixed plate 4012, a slider 4013, a reciprocating screw 4014, and a guide rod 4015. The motor 4011 can provide power for the movement of the reciprocating screw 4014, and the guide rod 4015 can restrict the movement trajectory of the slider 4013. The fixed plate 4012 is provided with a sliding groove 4016, and the slider 4013 is connected to the membrane breaking component 402 and can drive the membrane breaking component 402 to move along the sliding groove 4016.

[0044] When the movable component 401 is in use, the motor 4011 first drives the reciprocating screw 4014 to rotate up and down. The reciprocating screw 4014 first drives the slider 4013 to move downward, causing it to move the film-breaking component 402 downward. The film-breaking component will then break the film. As it continues to move downward, the film-breaking component 402 begins to dig a pit. The excavated soil remains in the film-breaking cylinder 40211. At this time, the motor 4011 starts to drive the slider 4013 to rise through the reciprocating screw 4014. The slider 4013 simultaneously drives the film-breaking component to rise. As cylinder 40211 rises, the power wheel 101 simultaneously begins to move forward. As the slider 4013 continues to rise, the membrane breaking assembly 402 first rises vertically along the chute 4016. When it rises to the upper part, the membrane breaking assembly 402 begins to move horizontally along the chute 4016. Since the slider 4013 is also rising at this time, during the horizontal displacement of the membrane breaking assembly 402, the soil inside the membrane breaking assembly 402 will be completely ejected and fall onto the soil transport mechanism 30, and then be transported into the soil covering box 203 by the soil transport mechanism 30.

[0045] In another specific embodiment, the slider component 4013 includes a slider 4017, a first sliding groove rod 4018, a second sliding groove rod 4019, a mounting post 4020, and a spring 4021. The slider 4017 has a mounting hole 4022 and a limiting hole 4023. The mounting hole 4022 passes vertically through the slider 4017, and the limiting hole 4023 passes horizontally through the slider 4017. The first sliding groove rod 4018 and the second sliding groove rod 4019 are symmetrically arranged at both ends of the membrane breaking assembly 402 and pass through the limiting hole 4023. One end of the first sliding groove rod 4018 is fixedly connected to the membrane breaking assembly 402, and the other end is engaged in the sliding groove. One end of the second sliding groove rod 4019 is connected to the membrane breaking assembly 402, and the other end is connected to the spring 4021. The mounting post 4020 is fixedly connected to the slider 4017, and the mounting post 4020 is connected to the other end of the spring 4021.

[0046] The membrane breaking assembly 402 is mounted on the membrane breaking assembly 402 through the mounting hole 4022. A first sliding rod 4018 and a second sliding rod 4019 are respectively located on both sides of the membrane breaking assembly 402. The first sliding rod 4018 and the second sliding rod 4019 pass through the limiting hole 4023 on the slider 4017. The mounting hole 4022 extends vertically along the horizontal plane of the slider 4017. The limiting hole 4023 is located on the side of the slider 4017 and extends horizontally through it. During installation, the reciprocating screw 4014 can drive the slider 4017 to move up and down. Since the second sliding rod 4019 is fixedly connected to the membrane breaking assembly 402 through the limiting hole 4023, thus… The film-breaking component 402 also moves along with the slider 4017. In use, the mounting post 4020 is fixedly installed at one end of the slider 4017. One end of the spring 4021 is connected to the mounting post 4020, and the other end is connected to the second slide bar 4019. When the film-breaking component 402 reaches the leftmost end of the slide bar, in order to enable the film-breaking component 402 to move up and down along the slide bar, the spring 4021 is installed between the second slide bar 4019 and the mounting post 4020. When the film-breaking component 402 moves to the leftmost end of the slide bar, the spring 4021 will be compressed. When the film-breaking component 402 performs the next film-breaking and pit-digging operation, the spring 4021 will push the film-breaking component 402 to move to the right.

[0047] In a preferred embodiment, the movable component 401 further includes a pressure plate 4024, which is perpendicular to the fixed plate 4012.

[0048] When the membrane breaking assembly 402 moves upward, in order to apply a downward force to the membrane breaking assembly 402 and expel the soil inside the membrane breaking assembly 402, a pressure plate 4024 is set. The pressure plate 4024 is set perpendicular to the fixed plate 4012. In order to limit the height of the movement of the membrane breaking assembly 402 and to expel the soil inside the membrane breaking assembly 402, when the membrane breaking assembly 402 moves up and down along the slide 4016, the membrane breaking assembly 402 will come into contact with the pressure plate 4024. At this time, the pressure plate 4024 will apply a downward pressure to the membrane breaking assembly 402, causing the soil inside the membrane breaking assembly 402 to be expelled.

[0049] In a preferred embodiment, the membrane breaking assembly 402 includes a membrane breaking cylinder 40211, a piston rod 40212, and a pressure cap 40213. The piston rod 40212 is disposed inside the membrane breaking cylinder 40211 and can move up and down along the vertical direction of the membrane breaking cylinder 40211. The pressure cap 40213 is fixedly connected to one end of the piston rod 40212.

[0050] In use, the slider 4017 drives the membrane-breaking cylinder 40211 to move downwards first, breaking the membrane. As it continues downwards, the membrane-breaking cylinder 40211 begins to dig a pit. The excavated soil remains inside the membrane-breaking cylinder 40211, and the pressure cap 40213 is then pushed upwards by the piston rod 40212. The working principle of the membrane-breaking cylinder 40211, piston rod 40212, and pressure cap 40213 is similar to that of a syringe. When there is soil inside the membrane-breaking cylinder 40211, the pressure cap 40213 is lifted by the piston rod 40212. Because the slide groove 4016 is a V-shaped slide groove, when the membrane-breaking cylinder 40211 moves, it first moves along... As the chute 4016 moves up and down, when the film-breaking cylinder 40211 slowly moves upward along the chute 4016, the pressure cap 40213 will come into contact with the pressure plate 4024. At this time, the pressure plate 4024 will apply a downward force to the pressure cap 40213, slowly pressing out the soil inside the film-breaking cylinder 40211. As the height of the film-breaking cylinder 40211 rising in the chute 4016 changes continuously, when the film-breaking cylinder 40211 reaches the top of the chute 4016, the film-breaking cylinder 40211 will move horizontally along the chute 4016. At this time, the soil inside the film-breaking cylinder 40211 will be pressed out, and the pressed-out soil will fall into the soil covering box 203.

[0051] Specific usage process: After the transport mechanism 10 travels a certain distance, it stops. At this time, the film-breaking cylinder 40211 moves downward under the action of the motor 4011 to break the soil. During the soil breaking, the film-breaking cylinder 40211 moves downward along the vertical chute of the V-shaped chute. During the downward movement, the film-breaking cylinder 40211 will first contact the film covering. Under the action of gravity, the film-breaking cylinder 40211 will break the film covering, thus breaking the film. Then, it will contact the soil and begin to dig a pit under the action of gravity. When digging a pit, if a pit 5cm deep needs to be dug, the control... The film-breaking cylinder 40211 is embedded in the soil to a depth of approximately 7cm. When excavating soil, if a 5cm deep pit is dug, the soil inside the film-breaking cylinder 40211 will be loose and will fall out. However, with an embedding depth of approximately 7cm, the soil inside the film-breaking cylinder 40211 is compacted, preventing it from falling out as the cylinder rises. After excavation and pit excavation are completed, the film-breaking cylinder 40211 begins to move upwards, and the transport mechanism... 10. Start operation; As the film-breaking cylinder 40211 moves upward, it first moves upward along the vertical groove of the V-shaped chute. During this upward movement, the piston rod 40212 contacts the pressure plate 4024 located at the top of the fixed plate 4012. The pressure plate 4024 applies a downward force to the piston rod 40212, thus squeezing out the soil inside the film-breaking cylinder 40211 as it moves upward. Simultaneously, when the film-breaking cylinder 40211 reaches the top of the vertical groove of the V-shaped chute... At this time, the film-breaking cylinder 40211 will move along the horizontal chute of the seven-shaped chute, and the direction of movement is opposite to the direction of movement of the transport mechanism 10. When the film-breaking cylinder 40211 moves to the top of the horizontal chute of the seven-shaped chute, the soil inside the film-breaking cylinder 40211 has been emptied. At this time, using the characteristics of the spring itself, the film-breaking cylinder 40211 is pushed back along the mounting hole 4022 and the limiting hole 4023 to the top of the vertical chute of the seven-shaped chute, so as to start the next round of soil removal and pit digging operation, and the soil removed can fall into the previous pit dug.

[0052] The soil transport mechanism 30 can be configured as a structure similar to a conveyor belt. During use, it continuously performs closed-loop motion, transferring the soil that falls on it as it rotates.

[0053] In the specific implementation process, the pressure plate 4024 can be arranged parallel to the fixed plate 4012 or inclined on the fixed plate 4012. The specific arrangement method is selected according to the specific application, so as to better squeeze out the soil inside the membrane breaking cylinder 40211.

[0054] Meanwhile, the motor 4011 can be selected as a reciprocating motor. When the film-breaking cylinder 40211 moves upward, the motor 4011 rotates forward, and when the film-breaking cylinder 40211 moves downward, the motor 4011 rotates in reverse.

[0055] To ensure uniform soil covering, a drive wheel 2041 is installed on the outside of the seed box 202, and a driven wheel 2042 is installed on the outside of the soil covering box 203. During use, the drive wheel 2041 and driven wheel 2042 mesh together, ensuring that the drive wheel 2041 drives the driven wheel 2042 to rotate synchronously. Furthermore, the seed wheel 205 is vertically mounted inside the seed box 202 via a rotating shaft, and the soil covering wheel is vertically mounted inside the soil covering box 203 via a rotating shaft. This ensures that the seed trough 2051 and the soil covering trough 2061 rotate synchronously, achieving integrated sowing followed by soil covering. In operation, during sowing and covering with soil, the seed trough 2051 and the covering trough 2061 are set at a certain angle. When rotating, the seed trough 2051 first connects to the outlet 2031, allowing the seeds in the seed trough 2051 to fall into the planting area. Then, during rotation, the covering trough 2061 drops the soil inside into the outlet 2031 to cover the planted seeds with soil. A certain amount of loose soil can be placed in the covering box 203 first. The loose soil ensures that the soil falling on the seeds is not clump-like, ensuring the uniformity of the covering and improving the germination rate of the seeds.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
