Description

Technical Field

[0001] This utility model relates to the field of bank slope greening technology, specifically to a vegetation planting device based on pneumatic principles. Background Technology

[0002] Due to global climate change and human activities, vegetation damage along riverbanks is becoming increasingly severe, leading to frequent problems such as soil erosion and riverbank collapse. Traditional bank protection methods, such as concrete or stone revetments, while offering some protection against erosion, lack ecological benefits and are detrimental to biodiversity conservation. Vegetation-based bank protection is a recognized eco-friendly approach; however, current methods rely heavily on artificial planting, which is not only inefficient but also costly. Furthermore, on steep riverbanks, artificial planting is extremely inconvenient and even poses safety risks.

[0003] Among existing greening technologies, hydroseeding is a novel technique suitable for greening highly weathered rock and soil slopes and soil-rock slopes. It utilizes a specialized sprayer to spray grass seeds, water-retaining agents, and other organic substrates onto the slope surface. Under pressure, the organic materials bind tightly to the slope, forming a substrate layer suitable for plant growth and development. Once the seeds germinate and vegetation grows, the slope is greened.

[0004] However, using hydroseeding for riverbank vegetation greening presents the following problems: 1. Riverbanks often have some natural vegetation, which is frequently sparse due to river erosion and requires replanting. Hydroseeding produces a highly viscous substrate that adheres densely to the slope, potentially killing existing vegetation. Therefore, hydroseeding is more suitable for bare slopes than for replanting existing vegetation. 2. Riverbanks, while not lacking water, are also susceptible to erosion, making the hydroseeded substrate easily washed away, thus negating the greening effect. 3. On steep rivers, boats often struggle to approach the banks, and hydroseeding's limited range makes it difficult to meet the distance requirements of riverbanks.

[0005] Therefore, how to design a greening and planting device based on the principle of hydroseeding, taking into account the characteristics of riverbank greening, is a problem that needs to be considered and solved by those skilled in the art. Utility Model Content

[0006] To address the aforementioned shortcomings, the technical problem this utility model aims to solve is: how to provide a vegetation planting device based on pneumatic principles that is designed specifically for the characteristics of riverbank greening, enabling faster and more efficient planting of vegetation along riverbanks, overcoming the limitations of steep riverbanks, reducing direct human involvement, lowering the risks of manual labor, and better improving the greening effect of riverbanks.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A vegetation planting device based on pneumatic principles includes a launching device at the front end and a pressure device at the rear end. The launching device comprises a horizontally forward-facing launching tube with a forward-facing launching port at the front end and an air inlet pipe connected to the rear end. A pneumatic pressure linkage switch mechanism is installed on the air inlet pipe. An upward-facing projectile inlet is provided at the rear of the launching tube, and a projectile compartment is fixedly connected to it. A projectile inlet control mechanism is also provided at the projectile inlet of the launching tube. The pressure device includes a piston device connected to the air inlet pipe, and the piston of the piston device is connected to a launching motor via a push-pull transmission mechanism.

[0009] In use, this device involves pre-mixing plant seeds and a nutrient substrate to create a bullet-shaped launcher, which is then installed in the launch chamber. The device is then mounted on a boat, and the launcher containing the plant seeds is propelled into the riverbank soil using compressed gas power. This method avoids damaging the existing vegetation on the riverbank, and the embedded seeds are not easily washed away by river water. After germination, the seeds absorb the nutrient substrate, quickly take root, and grow, achieving greening of the riverbank. Therefore, it better meets the needs of planting vegetation on riverbanks, especially for replanting in areas with weak vegetation, thus better achieving or maintaining the greening of riverbanks, protecting the environment through greening, and preventing soil erosion.

[0010] In operation, this device uses a motor to power a piston mechanism, causing it to move back and forth. As the piston moves forward, it generates air pressure, providing launch pressure for the launching device. Then, a pneumatic linkage switch mechanism opens the air inlet when the air pressure is sufficient, allowing the gas pressure to enter the launch tube and act on the bullet-shaped projectile. This gas pressure propels the projectile out of the launch tube and into the soil along the riverbank, quickly and efficiently planting seeds for vegetation on the riverbank. Therefore, this planting method overcomes the limitations of steep riverbanks, reduces direct human involvement, and lowers the risks associated with manual labor.

[0011] Furthermore, the piston device includes a piston cylinder, with the front outlet of the piston cylinder connected to the air inlet pipe, the rear end of the piston cylinder being open, a piston being slidably disposed inside the piston cylinder, and an air inlet being disposed outward at the front end of the circumferential side of the piston cylinder, with a one-way air inlet valve disposed at the air inlet.

[0012] In this way, as the piston moves forward, it compresses air to generate pressure, which then provides pressure to the intake pipe. This pressure continues until the air pressure linkage switch mechanism opens, at which point the air pressure pushes the launcher forward for firing. Then, as the piston retracts, the one-way intake valve at the intake port opens to replenish air, thus completing the cycle.

[0013] Furthermore, the push-pull transmission mechanism includes a push-pull rod, the front end of which is hinged to the middle of the rear end of the piston, and the rear end of which is eccentrically hinged to a turntable. The turntable is rotatably mounted on a turntable base, and a gear ring is provided on the outer periphery of the turntable and meshes with a drive gear. The drive gear is mounted on the output shaft of the transmitting motor.

[0014] In this way, the output of the transmitting motor drives the drive gear to rotate, which in turn drives the turntable to rotate through the cooperation of the drive gear and the gear ring. This, in turn, drives the piston through the push-pull rod to achieve the forward and backward pushing and pulling motion. Therefore, it has the advantages of simple structure, stable and reliable transmission, and convenient adjustment of the transmission ratio by setting the gear ratio of the gear ring and the drive gear.

[0015] Furthermore, the pneumatic linkage switch mechanism includes a first pressure block located at the front of the inner wall of the piston cylinder. The first pressure block is located behind the one-way air intake valve and is installed in a first mounting groove formed by an outward protrusion of the inner wall of the piston cylinder. The inward end face of the first pressure block is a rearward inclined surface, and the outward end is fixedly connected to a first pressure block connecting rod. The outer end of the first pressure block connecting rod slidably extends out of the piston cylinder and is connected to a first pull rope. A first return spring is also provided in the first mounting groove, sleeved on the first pressure block connecting rod. The first return spring acts on the first pressure block and causes the inclined surface of its inner end to just extend out of the inner opening of the first mounting groove. The pneumatic linkage switch mechanism also includes an air intake baffle. The plate is installed on an inwardly oriented switch step surface formed along the cross-sectional direction inside the air intake pipe. One end of the air intake baffle is hinged to one side of the switch step surface, and the other end is a rotatable movable end. A second mounting groove is formed on the inner wall of the air intake pipe on the other side of the switch step surface. A second pressure block is provided in the second mounting groove. The inner end of the second pressure block is the abutment end. A second pressure block connecting rod is fixedly connected to the outer end of the second pressure block. The outer end of the second pressure block connecting rod can slide out of the air intake pipe and connect to the front end of the first pull rope. A second return spring is also provided in the second mounting groove and sleeved on the second pressure block connecting rod. The second return spring acts on the second pressure block so that its abutment end can block the front side of the movable end of the air intake baffle.

[0016] In this way, as the piston moves forward, the intake baffle is pressed against the switch step surface and is in a closed state. The gas inside the piston cylinder is gradually compressed to form a large gas pressure. When the piston advances to the position of the first pressure block, it is squeezed by the inclined plane, causing the outer end of the first pressure block to push outward. This, in turn, pulls the second pressure block through the pull rope, causing the second pressure block to move outward and release the restriction on the intake baffle. The intake baffle is pushed open by the air pressure, and the airflow enters the launch tube through the intake pipe, causing the launcher to be ejected by the airflow to complete the launch. After the launch is completed, the suction effect generated during the piston's backward movement causes the intake baffle to reset. Then, after the first pressure block is no longer pressed by the piston, it is reset by the action of the first return spring, releasing the tension on the first pull rope. The second pressure block is reset by the action of the second return spring, and the intake baffle is blocked again. This completes one automatic firing cycle. Therefore, this structure can cleverly achieve automatic linkage between the piston and the intake baffle, so that the intake baffle can automatically open during the piston's forward movement, realizing automated control of the jet firing.

[0017] Furthermore, the outer end of the first pressure block connecting rod has a forward vertically extending bend, and a first fixed pulley is provided on the outer surface of the piston cylinder directly opposite the bend. The rear side of the protrusion of the second mounting groove on the air intake pipe extends downward to form an extension, and a second fixed pulley is provided on the front side of the extension. The starting end of the first pull rope is fixed on the bend at the outer end of the first pressure block connecting rod and extends inward to pass around the first fixed pulley, then obliquely upward to pass around the second fixed pulley and then extends inward to connect to the second pressure block connecting rod.

[0018] In this way, by setting up two fixed pulleys, the interaction between the first and second pressure blocks is achieved radially, which better ensures the stability and reliability of the action process.

[0019] Furthermore, the first pressure block is located on the lower side of the piston cylinder, and the second pressure block is located on the lower side of the air intake pipe. This makes it easier for the air intake baffle to reset under gravity. It also effectively avoids interference between the pneumatic linkage switch mechanism and the projectile control mechanism.

[0020] Furthermore, the rear side of the abutting end of the second pressure block has an L-shaped abutting groove, the abutting groove has an abutting surface that can fit with a part of the front side of the air intake baffle, the area where the abutting surface and the air intake baffle can fit together is the same as the distance of the inclined surface of the first pressure block protruding into the inner cavity of the piston cylinder along the radial dimension of the air intake pipe, and a tightening adjustment device is also installed on the first pull rope.

[0021] In this way, the length of the first pull rope can be adjusted by tightening the adjustment device. When the first pull rope is shorter, the contact area between the contact surface of the second pressure block and the air intake baffle is smaller, thus requiring a shorter travel distance along the inclined surface of the first pressure block during piston compression to open the air intake baffle. When the first pull rope is longer, the piston needs to travel a longer travel distance along the inclined surface of the first pressure block to open the air intake baffle. Therefore, by adjusting the length of the first pull rope, the stroke length of the piston when the air intake baffle is open can be adjusted, thereby regulating the amount of gas compression and further regulating the ejection speed of the projectile.

[0022] Furthermore, the tightening adjustment device includes a threaded cylinder and a threaded rod that are screwed together, with the opposite ends of the threaded cylinder and the threaded rod connected to the first pull rope.

[0023] This design offers advantages such as simple structure, convenient and quick adjustment, and stable and reliable operation.

[0024] Furthermore, the feed control mechanism includes a third pressure block located at the rear upper part of the inner wall of the piston cylinder. The third pressure block is installed in a third mounting groove formed by the outward protrusion of the inner wall of the piston cylinder. The inward end face of the third pressure block is a forward-facing inclined surface, and the outward end is fixedly connected to a third pressure block connecting rod. The outer end of the third pressure block connecting rod slidably extends out of the piston cylinder and is connected to the rear end of a second pull rope. A third return spring is also provided in the third mounting groove, sleeved on the third pressure block connecting rod. The third return spring acts on the third pressure block so that the inclined surface of its inner end is precisely... The second pull rope extends out of the inner opening of the third mounting slot; the front end of the second pull rope passes over the pulley group set on the outer surface of the piston cylinder and is connected forward to the rear end of a horizontally set launcher baffle. The front half of the launcher baffle is located in the inlet, and the rear half of the launcher baffle is located in a baffle mounting slot formed by an upward protrusion on the rear half of a launch tube. The rear end of the launcher baffle can slide horizontally out of the baffle mounting slot and is connected to the front end of the second pull rope. A fourth return spring is also provided in the baffle mounting slot. The fourth return spring acts on the launcher baffle to keep its front half in the inlet.

[0025] In this way, as the piston moves backward, it reaches the rear of the piston cylinder and contacts and presses against the inclined surface of the inner end of the third pressure block, pushing the third pressure block outward and pulling the rear end of the second pull rope. This pulls the launcher baffle backward, causing the front half of the launcher baffle to exit the inlet position. At this time, the launcher in the magazine above the inlet can fall downward into the launch tube, realizing the loading of the launcher. This achieves the automatic loading control effect of the launcher during the piston's backward movement. Therefore, the pneumatic linkage switch mechanism and the loading control mechanism work together to complete the continuous loading and automatic firing cycle of the launcher during the repeated back-and-forth movement of the piston. Thus, the automatic and continuous firing of the launcher is realized, quickly completing the planting process of plant seeds.

[0026] Furthermore, the outer end of the third pressure block connecting rod is connected to the rear end of the second pull rope via an adjusting lever. The fulcrum of the adjusting lever is hinged to a lever mounting seat that protrudes in the front direction on the outer surface of the third mounting groove. The rear end of the adjusting lever is a short support arm that abuts against the outer end of the third pressure block connecting rod, and the front end of the adjusting lever is a long support arm that is connected to the rear end of the downward-facing second pull rope.

[0027] In this way, after the third pressure block connecting rod extends outward, the second pulling rope can be pulled by adjusting the lever, which can amplify and increase the pulling distance, so that the length of the launcher can be set to be longer to accommodate more plant seeds.

[0028] Furthermore, in the launching device, there are multiple launching tubes arranged horizontally side by side, and the rear end of each launching tube is connected to the same air inlet pipe. The front end of the second pull rope is connected to multiple branch lines and is respectively connected to the launch body baffle at the rear of each launching tube.

[0029] In this way, the piston can control the firing of a row of projectiles in one round trip, thus improving planting efficiency.

[0030] Furthermore, both the launching device and the pressure device are mounted on a horizontally positioned base plate, with the lower front end of the base plate hinged to a base plate support, and a lifting control device located at the lower rear end of the base plate.

[0031] This allows for control and adjustment of the launch direction of the launch port as needed.

[0032] Furthermore, the lifting control device includes a lifting adjustment rack hinged at its upper end to the lower rear end of the base plate. The lifting adjustment rack is vertically slidably mounted on a vertical rack guide rail. The lifting adjustment rack meshes with a lifting adjustment gear, and the lifting adjustment gear is connected to the output shaft of a lifting adjustment motor. This enables automatic control of the lifting adjustment.

[0033] In summary, this utility model is designed specifically for the characteristics of riverbank greening. It not only enables continuous operation, reduces labor costs, and facilitates rapid planting of revegetation, but also overcomes the limitations of steep riverbanks, minimizing direct human involvement and reducing the risks associated with manual labor. This technology not only has significant economic, social, and ecological benefits, but also closely aligns with national policy guidelines, making it of significant value for promotion and application.

[0039] The present invention will now be described in further detail with reference to specific embodiments.

[0040] Preferred implementation: A vegetation planting device based on pneumatic principles, see [link to previous description]. Figure 1-5 As shown, it includes a launching device at the front end and a pressure device at the rear end. The launching device includes a horizontally forward-facing launching tube 1 with a forward-facing launching port at the front end and an air inlet pipe 2 connected to the rear end. A pneumatic linkage switch mechanism is installed on the air inlet pipe 2. A projectile inlet is opened upward at the rear of the launching tube 1 and is fixedly connected to a projectile compartment 3. A projectile inlet control mechanism is also provided at the projectile inlet of the launching tube 1. The pressure device includes a piston device connected to the air inlet pipe. The piston of the piston device is connected to a launching motor through a push-pull transmission mechanism.

[0041] In use, this device involves pre-mixing plant seeds (5) and a nutrient substrate to create a bullet-shaped launcher (4), which is then installed in the launch chamber. The device is then mounted on a boat, allowing the seed-containing launcher to be propelled into the riverbank soil using compressed gas. During operation, a motor powers a piston mechanism, driving it forward and backward. The forward movement of the piston generates air pressure, providing the launch pressure for the device. A pneumatic pressure-linked switch mechanism opens the air inlet when sufficient air pressure is available, allowing the gas pressure to enter the launch tube and act on the bullet-shaped launcher. This gas pressure propels the launcher out of the tube and into the riverbank soil, quickly and efficiently planting seeds on the riverbank. Therefore, this planting method overcomes the limitations of steep riverbanks, reduces direct human involvement, and lowers the risks associated with manual labor. In practice, the emitting body is made by adding plant seeds to a powdered nutrient matrix, then adding a certain proportion of water to adjust it into a viscous paste (a small amount of binder can be added if necessary to facilitate shaping), then pressing it into a long, bullet-shaped form using a bullet-shaped mold cavity, and then drying and curing it.

[0042] The piston device includes a piston cylinder 6, the front outlet of the piston cylinder 6 is connected to the air inlet pipe 2, the rear end of the piston cylinder 6 is open, a piston 7 is slidably arranged inside the piston cylinder, and an air inlet is also provided outward at the front end of the circumferential side of the piston cylinder 6, and a one-way air inlet valve 8 is provided at the air inlet.

[0043] In this way, as the piston moves forward, it compresses air to generate pressure, which then provides pressure to the intake pipe. This pressure continues until the air pressure linkage switch mechanism opens, at which point the air pressure pushes the launcher forward for firing. Then, as the piston retracts, the one-way intake valve at the intake port opens to replenish air, thus completing the cycle.

[0044] The push-pull transmission mechanism includes a push-pull rod 9. The front end of the push-pull rod 9 is hinged to the middle of the rear end of the piston 7. The rear end of the push-pull rod 9 is eccentrically hinged to a turntable 10. The turntable 10 is rotatably mounted on a turntable base. A gear ring 11 is provided on the outer periphery of the turntable 10 and meshes with a drive gear 12. The drive gear 12 is mounted on the output shaft of the transmitting motor 13.

[0045] In this way, the output of the transmitting motor drives the drive gear to rotate, which in turn drives the turntable to rotate through the cooperation of the drive gear and the gear ring. This, in turn, drives the piston through the push-pull rod to achieve the forward and backward pushing and pulling motion. Therefore, it has the advantages of simple structure, stable and reliable transmission, and convenient adjustment of the transmission ratio by setting the ratio of the number of teeth of the gear ring and the drive gear. In implementation, the gear ring can be a bevel gear ring or an annular gear ring, and the drive gear is a matching bevel gear or a spur gear.

[0046] The pneumatic linkage switch mechanism includes a first pressure block 21 located at the front of the inner wall of the piston cylinder. The first pressure block 21 is located behind the one-way air intake valve and is installed in a first mounting groove 22 formed by an outward protrusion of the inner wall of the piston cylinder. The inward end face of the first pressure block 21 is a rearward inclined surface, and the outward end is fixedly connected to a first pressure block connecting rod 23. The outer end of the first pressure block connecting rod 23 slidably passes through the piston cylinder and is connected to a first pull rope 24. A first return spring 25 is also provided in the first mounting groove and sleeved on the first pressure block connecting rod. The first return spring 25 acts on the first pressure block and makes the inclined surface of its inner end just extend out of the inner groove of the first mounting groove 22. The pneumatic linkage switch mechanism also includes an air intake baffle 26. 6 is installed on an inwardly oriented switch step surface formed along the cross-sectional direction inside the air intake pipe 2. One end of the air intake baffle 26 is hinged to one side of the switch step surface, and the other end is a rotatable movable end. A second mounting groove 27 is formed on the inner wall of the air intake pipe on the other side of the switch step surface. A second pressure block 28 is provided in the second mounting groove. The inner end of the second pressure block 28 is an abutting end. A second pressure block connecting rod 29 is fixedly connected to the outer end of the second pressure block. The outer end of the second pressure block connecting rod 29 can slide out of the air intake pipe and connect to the front end of the first pull rope 24. A second return spring 30 is also provided in the second mounting groove and sleeved on the second pressure block connecting rod. The second return spring 30 acts on the second pressure block 28 so that its abutting end can block the front side of the movable end of the air intake baffle.

[0047] In this way, as the piston moves forward, the intake baffle is pressed against the switch step surface and is in a closed state. The gas inside the piston cylinder is gradually compressed to form a large gas pressure. When the piston advances to the position of the first pressure block, it is squeezed by the inclined plane, causing the outer end of the first pressure block to push outward. This, in turn, pulls the second pressure block through the pull rope, causing the second pressure block to move outward and release the restriction on the intake baffle. The intake baffle is pushed open by the air pressure, and the airflow enters the launch tube through the intake pipe, causing the launcher to be ejected by the airflow to complete the launch. After the launch is completed, the suction effect generated during the piston's backward movement causes the intake baffle to reset. Then, after the first pressure block is no longer pressed by the piston, it is reset by the action of the first return spring, releasing the tension on the first pull rope. The second pressure block is reset by the action of the second return spring, and the intake baffle is blocked again. This completes one automatic firing cycle. Therefore, this structure can cleverly achieve automatic linkage between the piston and the intake baffle, so that the intake baffle can automatically open during the piston's forward movement, realizing automated control of the jet firing.

[0048] The first pressure block connecting rod 23 has a forward vertically extending bent portion at its outer end. A first fixed pulley 31 is provided on the outer surface of the piston cylinder directly opposite the bent portion. The rear side of the protrusion of the second mounting groove on the air intake pipe extends downward to form an extension portion. A second fixed pulley 32 is provided on the front side of the extension portion. The starting end of the first pull rope 24 is fixed on the bent portion at the outer end of the first pressure block connecting rod and extends inward to pass around the first fixed pulley 31, then obliquely upward to pass around the second fixed pulley 32, and then extends inward to connect to the second pressure block connecting rod 29.

[0049] In this way, by setting up two fixed pulleys, the interaction between the first and second pressure blocks is achieved radially, which better ensures the stability and reliability of the action process.

[0050] The first pressure block 21 is located on the lower side of the piston cylinder 6, and the second pressure block 28 is located on the lower side of the air intake pipe 2. This makes it easier for the air intake baffle to reset under gravity. It also effectively avoids interference between the pneumatic linkage switch mechanism and the projectile control mechanism.

[0051] The second pressure block 28 has an L-shaped abutment groove on the rear side of its abutment end. The abutment groove has an abutment surface that can fit with a part of the front side of the air intake baffle. The radial dimension of the area where the abutment surface and the air intake baffle can fit together is the same as the distance by which the inclined surface of the first pressure block 21 protrudes into the inner cavity of the piston cylinder. A tightening adjustment device 33 is also installed on the first pull rope 24.

[0052] In this way, the length of the first pull rope can be adjusted by tightening the adjustment device. When the first pull rope is shorter, the contact area between the contact surface of the second pressure block and the air intake baffle is smaller, thus requiring a shorter travel distance along the inclined surface of the first pressure block during piston compression to open the air intake baffle. When the first pull rope is longer, the piston needs to travel a longer travel distance along the inclined surface of the first pressure block to open the air intake baffle. Therefore, by adjusting the length of the first pull rope, the stroke length of the piston when the air intake baffle is open can be adjusted, thereby regulating the amount of gas compression and further regulating the ejection speed of the projectile.

[0053] The tightening adjustment device 33 includes a threaded cylinder and a threaded rod that are screwed together, with the opposite ends of the threaded cylinder and the threaded rod connected to the first pull rope.

[0054] This design offers advantages such as simple structure, convenient and quick adjustment, and stable and reliable operation.

[0055] The feed control mechanism includes a third pressure block 41 located at the rear of the inner wall of the piston cylinder. The third pressure block 41 is installed in a third mounting groove 42 formed by the outward protrusion of the inner wall of the piston cylinder 6. The inward end face of the third pressure block 41 is a forward-facing inclined surface, and the outward end is fixedly connected to a third pressure block connecting rod 43. The outer end of the third pressure block connecting rod slidably extends out of the piston cylinder and is connected to the rear end of a second pull rope 44. A third return spring 45 is also provided in the third mounting groove and sleeved on the third pressure block connecting rod. The third return spring 45 acts on the third pressure block so that the inclined surface of its inner end just extends. The second pull rope 44 passes through the pulley group 46 set on the outer surface of the piston cylinder and is connected forward to the rear end of a horizontally set launcher baffle 47. The front half of the launcher baffle 47 is located in the inlet, and the rear half of the launcher baffle 47 is located in a baffle mounting groove formed by an upward protrusion on the rear half of the launch tube. The rear end of the launcher baffle can slide horizontally out of the baffle mounting groove and is connected to the front end of the second pull rope. A fourth return spring 48 is also set in the baffle mounting groove. The fourth return spring 48 acts on the launcher baffle 47 to keep its front half in the inlet.

[0056] In this way, as the piston moves backward, it reaches the rear of the piston cylinder and contacts and presses against the inclined surface of the inner end of the third pressure block, pushing the third pressure block outward and pulling the rear end of the second pull rope. This pulls the launcher baffle backward, causing the front half of the launcher baffle to exit the inlet position. At this time, the launcher in the magazine above the inlet can fall downward into the launch tube, realizing the loading of the launcher. This achieves the automatic loading control effect of the launcher during the piston's backward movement. Therefore, the pneumatic linkage switch mechanism and the loading control mechanism work together to complete the continuous loading and automatic firing cycle of the launcher during the repeated back-and-forth movement of the piston. Thus, the automatic and continuous firing of the launcher is realized, quickly completing the planting process of plant seeds.

[0057] The outer end of the third pressure block connecting rod 43 is connected to the rear end of the second pull rope 44 by an adjusting lever 50. The fulcrum of the adjusting lever 50 is hinged to a lever mounting seat that protrudes in the front direction on the outer surface of the third mounting groove. The rear end of the adjusting lever 50 is a short support arm that abuts against the outer end of the third pressure block connecting rod 43, and the front end of the adjusting lever is a long support arm that is connected to the rear end of the downward-facing second pull rope.

[0058] In this way, after the third pressure block connecting rod extends outward, the second pulling rope can be pulled by adjusting the lever, which can amplify and increase the pulling distance, so that the length of the launcher can be set to be longer to accommodate more plant seeds.

[0059] In the launching device, there are multiple launching tubes 1 arranged horizontally side by side, and the rear end of each launching tube 1 is connected to the same air inlet pipe 2. The front end of the second pull rope 44 is connected to multiple branch lines and is respectively connected to the launch body baffle 47 at the rear of each launching tube.

[0060] In this way, the piston can control the firing of a row of projectiles in one round trip, thus improving planting efficiency.

[0061] The launching device and the pressure device are both mounted on a horizontally set base plate 51. The lower front end of the base plate 51 is hinged to a base plate support 52, and a lifting control device is set at the lower rear end of the base plate 51.

[0062] This allows for control and adjustment of the launch direction of the launch port as needed.

[0063] The lifting control device includes a lifting adjustment rack 53 hinged at its upper end to the lower rear end of the base plate. The lifting adjustment rack is vertically slidably mounted on a vertical rack guide rail 54. The lifting adjustment rack 53 meshes with a lifting adjustment gear 55, which is connected to the output shaft of a lifting adjustment motor 56. This enables automatic control of the lifting adjustment.
