Description

Technical Field

[0001] This invention relates to the field of perforation devices, specifically a perforation device for a seed-making machine film. Background Technology

[0002] In the field of mechanized agricultural sowing, strip seed film is an agricultural film made of polymer materials such as polyethylene. It is used in conjunction with strip seeders. During sowing operations, the strip seed film is evenly laid on the soil surface to form an isolation layer. It can not only effectively inhibit weed growth and reduce soil erosion, but also create a stable temperature and humidity environment for seed germination, playing an important role in modern agricultural production.

[0003] Mulching corn is an important agronomic measure to increase crop yield. Mulching can reduce soil heat loss, providing a significant heat preservation effect, and can also effectively reduce water evaporation, thus achieving the goal of moisture retention. However, traditional mulching requires manually or mechanically breaking the film to release the seedlings before emergence, which not only consumes a lot of manpower and resources, but also carries the risk of seedling burn if the release is not timely. To further improve production efficiency, the film-perforated sowing technology has emerged. This technology directly punches holes in the film and completes the sowing, eliminating the need for the subsequent film-breaking process.

[0004] Currently, although there are various punching devices available on the market that are compatible with row seeders, they generally have technical shortcomings. Most punching devices have a relatively simple structural design and rely on mechanical synchronous control. During the sowing process, they are easily affected by factors such as mechanical vibration and differences in soil texture, which can cause the punching position to be misaligned with the seed placement position, resulting in seedling suffocation during the growth process. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a perforation device on the film of a strip seeder for sowing, so as to solve the technical problem that existing perforation devices are prone to misalignment with the seed placement position during the perforation process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a perforation device on a film of a strip seeder for sowing, comprising a strip seeder, wherein multiple seed boxes are installed inside the strip seeder, a seeder is connected to the bottom of the seed box, an infrared sensor is installed inside the seeder, multiple perforators are installed on one side of the strip seeder, a stepper motor is installed on one side of the perforator, a drive assembly is connected to the end of the stepper motor, the drive assembly includes a perforation rod, a perforation head is installed at the end of the perforation rod, two sets of rollers are installed on both sides of the end of the strip seeder, and speed sensors are installed on the rollers, and a control panel is installed on the top of the strip seeder.

[0007] By adopting the above technical solution, the problem of misalignment between the existing punching device and the seed placement position during the punching process is solved. During the movement of the row seeder, the infrared sensor inside the seeder detects the seed fall in real time, and the control panel can dynamically adjust the seeding frequency of the seeder according to the rolling speed. When the rolling distance is equal to the distance between the puncher and the seeder, the control panel simultaneously controls multiple sets of seeders to punch holes in the mulch film through the punching head. The seed sowing frequency and the punching frequency of the punching head on the film are both controlled by the control panel according to the number of rotations of the roller, thereby reducing the error between the punching position of the punching head on the film and the seed sowing position.

[0008] The present invention is further configured such that the control panel adopts an STM single-chip microcomputer control integrated module, and the control panel is electrically connected to the seeder and the roller.

[0009] Preferably, the control panel collects data on the roller movement speed, thereby facilitating the control system inside the control panel to control the operation of the seeder and the stepper motor.

[0010] The present invention is further configured such that a connecting rod is connected to the top of the punching rod, a crank rod is provided at the end of the connecting rod, and one end of the crank rod is fixedly provided at the output end of the stepper motor.

[0011] Preferably, the stepper motor drives the connecting rod through the crank, and the rotating connecting rod drives the punching rod to move up and down, thereby providing power for the raising and lowering of the punching head.

[0012] The present invention is further configured such that a limiting block is sleeved on the outer wall of the punching rod, and the limiting block is fixedly installed on the inside of the puncher.

[0013] Preferably, when the connecting rod drives the punching rod to move up and down, the limiting block limits the movement direction of the punching rod, so that the punching rod can move up and down in the vertical direction.

[0014] The present invention is further configured such that both ends of the connecting rod are equipped with fixing rings, and connectors are provided inside the fixing rings.

[0015] Preferably, two sets of connectors movably connect the two ends of the connecting rod to the crank rod and the punch rod, respectively.

[0016] The invention is further configured such that the connector is composed of bolts and nuts, and two sets of connectors movably connect the two ends of the connecting rod to the crank rod and the punch rod, respectively.

[0017] Preferably, the connecting rod and the crankshaft are connected by a connector, which facilitates the disassembly of the connecting rod and the crankshaft by personnel.

[0018] The present invention is further configured such that multiple sets of mounting slots are provided on one side of the crank arm, and the multiple sets of mounting slots are equally spaced.

[0019] Preferably, when the connector is installed in different mounting slots, the lifting distance of the punching rod pushing the punching head is also different, thereby realizing the control of the punching depth of the punching head.

[0020] The present invention is further configured such that two sets of pressure rollers are installed on both sides of the punch, and the width of the pressure rollers is greater than the diameter of the punch head.

[0021] Preferably, when the punching head punches the film, two sets of pressure rollers press and fix the film on both sides. The pressing action of the pressure rollers can flatten the wrinkles of the film, keep the film surface flat and tight, reduce the wrinkles generated in the film, and thus ensure the integrity of the film holes.

[0022] In summary, the present invention has the following main beneficial effects: 1. This invention solves the problem of misalignment between the existing perforation device and the seed placement position during the perforation process by setting up a strip seeder, a seeder, rollers, and a perforator. During the movement of the strip seeder, the infrared sensor inside the seeder detects the seed fall in real time, and the control panel can dynamically adjust the seeding frequency of the seeder according to the speed of the rollers. When the roller rotation distance is equal to the distance between the perforator and the seeder, the control panel simultaneously controls multiple sets of seeders to perforate the film through the perforation head. The seed sowing frequency and the perforation frequency of the perforation head on the film are both controlled by the control panel according to the number of rotations of the rollers, thereby reducing the error between the perforation position of the perforation head on the film and the seed sowing position.

[0023] 2. This invention, by setting up a control panel, a seeder, and a stepper motor, allows the operator to adjust and reset the initial angle of the stepper motor using the control buttons on the control panel when using the row seeder for the first time. When the operator presses the control button, the stepper motor drives the crank connected to the output end to rotate until the end of the crank is vertically upward. The crank drives the punching rod to move vertically upward through the connecting rod, raising the punching head to the highest position. This ensures that when the seeder sows the first seed during the initial operation of the row seeder, the punching head is at the waiting position height, thus guaranteeing the accuracy between the punching position of the punching head on the film and the seed sowing position.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of the present invention will now be described.

[0028] Please see Figure 1 — Figure 5 The system includes a row seeder 1, which has multiple seed boxes 101 installed inside. A seeder 102 is connected to the bottom of each seed box 101, and an infrared sensor is installed inside each seeder 102. Multiple punches 2 are installed on one side of the row seeder 1, and a stepper motor 201 is installed on one side of each punch. A drive assembly is connected to the end of the stepper motor 201, and the drive assembly includes a punching rod 204. A punching head 205 is installed at the end of the punching rod 204. Two sets of rollers 103 are installed on both sides of the end of the row seeder 1, and speed sensors are installed on the rollers 103. A control panel 104 is installed on the top of the row seeder 1. This system solves the problem that existing punching devices are prone to misalignment with the seed placement position during the punching process. To address the issue of seed misalignment, during the forward movement of the row seeder 1, the infrared sensor inside the seeder 102 detects the seed fall in real time. Furthermore, the control panel 104 dynamically adjusts the seeding frequency of the seeder 102 based on the traveling speed of the roller 103. When the rotation distance of the roller 103 equals the distance between the punch 2 and the seeder 102, the control panel 104 simultaneously controls multiple sets of seeders 2 to punch holes in the plastic film through the punching head 205. Both the seed sowing frequency and the punching frequency of the punching head 205 are controlled by the control panel 104 based on the number of rotations of the roller 103, thereby reducing the error between the punching position of the punching head 205 and the seed sowing position.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2The control panel 104 adopts an STM32 microcontroller control integrated module, and the control panel 104 is electrically connected to the seeder 102 and the roller 103. The control panel 104 collects the movement speed data of the roller 103, thereby facilitating the internal control system of the control panel 104 to control the operation of the seeder 102 and the stepper motor 201.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The top of the punching rod 204 is connected to a connecting rod 203, and the end of the connecting rod 203 is provided with a crank rod 202. One end of the crank rod 202 is fixedly set at the output end of the stepper motor 201. The stepper motor 201 drives the connecting rod 203 to rotate through the crank rod 202. The rotating connecting rod 203 drives the punching rod 204 to move up and down, thereby providing power for the lifting and lowering of the punching head 205.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The outer wall of the punching rod 204 is fitted with a limiting block 206, and the limiting block 206 is fixedly installed inside the puncher 2. When the connecting rod 203 drives the punching rod 204 to move up and down, the limiting block 206 limits the movement direction of the punching rod 204, so that the punching rod 204 can move up and down in the vertical direction.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 Both ends of the connecting rod 203 are equipped with retaining rings 209, and connectors 208 are provided inside the retaining rings 209. The two sets of connectors 208 movably connect the two ends of the connecting rod 203 to the crank rod 202 and the punch rod 204, respectively.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The connector 208 is composed of bolts and nuts, and two sets of connectors 208 connect the two ends of the connecting rod 203 to the crank rod 202 and the punch rod 204 respectively. The connecting rod 203 and the crank rod 202 are connected through the connector 208, which facilitates the disassembly of the connecting rod 203 and the crank rod 202 by personnel.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The crank lever 202 has multiple sets of mounting slots 210 on one side, and the multiple sets of mounting slots 210 are equally spaced. When the connector 208 is installed in different mounting slots 210, the drilling rod 204 pushes the drilling head 205 to move up and down by different distances, thereby controlling the drilling depth of the drilling head 205.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 3Two sets of pressure rollers 207 are installed on both sides of the punch 2, and the width of the pressure rollers 207 is greater than the diameter of the punch head 205. When the punch head 205 punches the film, the two sets of pressure rollers 207 squeeze and fix the two sides of the film. The squeezing action of the pressure rollers 207 can flatten the wrinkles of the film, keep the film surface flat and tight, reduce the wrinkles generated by the film, and thus ensure the integrity of the film holes.

[0036] In practical operation, when using the strip seeder 1 for the first time, the operator adjusts and resets the initial angle of the stepper motor 201 using the control button on the control panel 104. When the operator presses the control button, the stepper motor 201 drives the crank 202 connected to the output end to rotate until the end of the crank 202 is vertically upward. The crank 202 drives the punching rod 204 to move vertically upward through the connecting rod 203, so that the punching rod 204 raises the punching head 205 to the highest position. During the sowing operation, the row seeder 1 is pulled forward by a tractor to achieve synchronous operation. The corn seeds stored inside the seed box 101 are evenly dropped into the soil by the clamping mechanism of the seeder 102. During the seed falling process, the infrared sensor installed inside the seeder 102 is detected in real time. Since a speed sensor is installed on the roller 103 at the tail of the seeder 1, and the data detected by the speed sensor on the roller 103 is transmitted to the control panel 104 in real time, the control panel 104 can dynamically adjust according to the traveling speed. The seeding frequency of the seeder 102 is adjusted. In addition, the distance between the punch 2 and the seeder 102 remains constant. When the rotation distance of the roller 103 is equal to the distance between the punch 2 and the seeder 102, the control panel 104 controls the stepper motors 201 set on the top of the multiple seeders 2 to operate. The stepper motors 201 drive the connecting rod 203 to rotate through the crank 202. The connecting rod 203 drives the punching rod 204 to reciprocate linearly within the limit block 206, so that the punching head at the end of the punching rod 206 punches holes in the mulch film.
