Description

Technical Field

[0001] The present invention relates to the technical field of bank slope greening, and particularly to a method for planting vegetation on river bank slopes. Background Art

[0002] Affected by global climate change and human activities, the vegetation on both sides of rivers has been increasingly damaged, resulting in frequent problems such as soil erosion and river bank collapse. Traditional bank protection methods mostly use concrete slope protection or stone bank protection. Although they can prevent erosion to a certain extent, they lack ecological benefits and are not conducive to the protection of biodiversity. Vegetation bank protection is a recognized eco-friendly bank protection method. However, existing bank protection vegetation mostly relies on manual planting, which is not only inefficient but also costly. In addition, when the river bank slope is relatively large, it is extremely inconvenient to manually plant bank protection vegetation, and there are even operation safety risks.

[0003] In existing greening technologies, spraying sowing is a new technology suitable for greening weathered rock slopes and soil-rock slopes with a relatively high degree of weathering. It uses a special spraying machine to spray grass seeds, water retention agents and other organic substrates onto the slope surface. Under the action of pressure, the organic materials are closely combined with the slope surface to form a substrate layer for plant growth and development. In this way, after the seeds germinate and grow vegetation, the slope can be greened.

[0004] However, for the vegetation greening of river bank slopes, if this spraying sowing method is used, the following problems will occur: 1. There are often some natural vegetations on river bank slopes. In more cases, the vegetation becomes sparse due to river water scouring and needs to be replanted. However, the matrix sprayed by the spraying sowing method has a relatively high viscosity, and after the matrix is sprayed, it will adhere densely to the slope, which will instead cause the death of existing plants. Therefore, the spraying sowing method is more suitable for implementing on bare slopes and not suitable for the need of replanting and greening slopes with existing vegetation. 2. The river bank slopes are close to the river and do not lack water, but they are easily eroded by river water scouring, making the sprayed matrix easily washed away by river water and losing the greening effect. 3. For some steep rivers, it is often difficult for boats to approach the bank, but the spraying sowing method has a limited distance and is difficult to better meet the distance requirements of river bank slopes.

[0005] Therefore, how to design a greening planting scheme similar to the principle of spraying sowing according to the characteristics of river bank slope greening is a problem that needs to be considered and solved by those skilled in the art. Summary of the Invention

[0006] Aiming at the above deficiencies, the technical problem to be solved by the present invention is: how to provide a method for planting vegetation on river bank slopes that is designed according to the characteristics of river bank slope greening, can more quickly and efficiently realize the planting of bank protection plants, overcome the limitation of river bank steep slopes, reduce direct human participation, reduce the risk of manual operations, and better improve the greening effect of river bank slopes.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: A method for planting vegetation on a river bank slope, characterized in that plant seeds and nutrient matrix are mixed to make bullet-shaped projectiles, and then compressed gas is used as power to launch the projectiles from a river boat and embed them into the soil on the river bank slope to achieve vegetation planting.

[0008] In this way, the method can launch the projectile containing plant seeds into the soil of the bank slope by compressed gas power, without damaging the original vegetation of the bank slope. At the same time, the plant seeds are embedded in the soil and will not be easily washed away by the river water. After the seeds germinate, they absorb the nutrient matrix and quickly take root and grow, realizing the greening of the bank slope. Therefore, the method can better meet the needs of planting vegetation on the river bank slope, especially replanting weak positions of green plants, better realize or maintain the greening of the river bank slope, realize the greening protection of the environment, and avoid soil and water loss. During implementation, the projectile adopts plant seeds to add powdered nutrient matrix, and then adds a certain proportion of water to adjust it to a viscous paste material (a small amount of binder can be added to facilitate forming if necessary), and then uses a bullet-shaped mold cavity to press and form it into a long strip of bullet shape, and then dry and solidify it.

[0009] Furthermore, the method is implemented by a river bank vegetation planting device installed on a river vessel, the river bank vegetation planting device comprising a launching device at the front end and a pressure device at the rear end, the launching device comprising a launching tube arranged forward, the front end of the launching tube being a launching port forward, the rear end being connected rearwardly with an air intake pipe, the air intake pipe being provided with a pneumatic linkage switch mechanism, an upwardly opened bullet feed port being provided at the rear end of the launching tube and a bullet bay being fixedly connected upwardly, the bullet bay being used to hold a projectile, the projectile being made into a bullet shape by mixing plant seeds and a nutrient matrix, and a bullet feed control mechanism being further provided at the bullet feed port of the launching tube; the pressure device comprising a piston device connected to the air intake pipe, the piston of the piston device being connected to a launching motor via a push-pull transmission mechanism.

[0010] In this way, when the device is used, the motor provides power to the piston device to drive the piston to move forward and backward. When the piston moves forward, the generated air pressure provides the launch pressure for the launch device. Then, the air pressure linkage switch mechanism opens the air intake pipe when the air pressure is sufficient, so that the gas pressure enters the launch tube and acts on the bullet-shaped projectile. The projectile is ejected from the launch tube by relying on the gas pressure and driven into the soil on the bank, so as to quickly and efficiently realize the planting of green plant seeds on the river bank slope. Therefore, the planting method realized based on this device overcomes the limitation of steep slope of river bank, reduces the direct participation of personnel, and reduces the risk of manual operation.

[0011] Further, the piston device includes a piston cylinder. The front end outlet of the piston cylinder is connected to the intake pipe, and the rear end of the piston cylinder is open. A piston is slidably arranged in the piston cylinder. An air inlet is also arranged outward at the front end position of the circumferential side of the piston cylinder, and a one-way intake valve is arranged at the air inlet.

[0012] In this way, when the piston moves forward, it can compress the air to generate air pressure to provide pressure for the intake pipe until the air pressure linkage switch mechanism is opened, and then the air pressure pushes the projectile to spray forward and launch. Then, during the backward movement of the piston, the one-way intake valve at the air inlet opens to achieve air intake and air replenishment, thus realizing the cycle.

[0013] Further, the push-pull transmission mechanism includes a push-pull rod. The front end of the push-pull rod is hinged to the middle position of the rear end of the piston, and the rear end of the push-pull rod is eccentrically hinged to a turntable. The turntable is rotatably installed on the turntable base. A toothed ring is arranged at the outer peripheral position of the turntable and meshes with a driving gear. The driving gear is installed on the output shaft of the launch motor.

[0014] In this way, the output of the launch motor drives the driving gear to rotate, and then drives the turntable to rotate through the cooperation of the driving gear and the toothed ring, and then drives the piston to realize the forward and backward push-pull movement through the push-pull rod. Therefore, it has the advantages of simple structure, stable and reliable transmission, and the transmission ratio is convenient to be adjusted by setting the tooth number ratio of the toothed ring and the driving gear.

[0015] Further, the air pressure linkage switch mechanism includes a first pressing block located at the front part of the inner side wall of the piston cylinder. The first pressing block is located at the rear side of the one-way intake valve and is installed in a first installation groove formed by the outward protrusion of the inner side wall of the piston cylinder. The end face of the inner end of the first pressing block is a backward inclined plane, and a first pressing block connecting rod is fixedly connected outward at the outer end. The outer end of the first pressing block connecting rod can slidably penetrate out of the piston cylinder and is connected with a first pull rope. A first return spring sleeved on the first pressing block connecting rod is also arranged in the first installation groove. The first return spring acts on the first pressing block so that the inclined plane at its inner end just extends out of the inner notch of the first installation groove; the air pressure linkage switch mechanism also includes an intake baffle. The intake baffle is installed on an inward switch step surface formed along the cross-section direction in the inner cavity of the intake pipe. One end of the intake baffle is hinged to one side of the switch step surface, and the other end is a rotatable movable end. A second installation groove is formed by the outward protrusion of the inner wall of the intake pipe on the other side of the switch step surface. A second pressing block is arranged in the second installation groove. The inner end of the second pressing block is an abutting end, and a second pressing block connecting rod is fixedly connected outward at the outer end. The outer end of the second pressing block connecting rod can slidably penetrate out of the intake pipe and is connected to the front end of the first pull rope. A second return spring sleeved on the second pressing block connecting rod is also arranged in the second installation groove. The second return spring acts on the second pressing block so that its abutting end can block the front side of the movable end of the intake baffle.

[0016] In this way, during the forward movement of the piston, the intake baffle presses on the switch step surface and is in the closed state. The gas in the piston cylinder is gradually compressed to form a relatively large gas pressure. When the piston advances to the position of the first pressing block, it squeezes the first pressing block through the action of the inclined plane, causing the outer end of the first pressing block to protrude outward. Then, the second pressing block is pulled through the pull rope, causing the second pressing block to be pulled and move outward, releasing the restriction on the intake baffle. The intake baffle is pushed open by the air pressure, and the air flow enters the launch tube through the intake pipe, causing the projectile to be driven by the air flow and ejected to complete the launch. After the launch is completed, during the backward movement of the piston, the suction effect generated causes the intake baffle to reset. Then, after the first pressing block loses the suppression of the piston, it resets under the action of the first return spring, releasing the tension on the first pull rope. The second pressing block resets under the action of the second return spring and blocks the intake baffle again. One automatic firing is completed. Therefore, this structure can cleverly complete the automatic linkage between the piston and the intake baffle, enabling the intake baffle to automatically open during the forward movement of the piston, realizing the automatic control of the ejection excitation.

[0017] Further, the outer end of the first pressing block connecting rod has a folded portion that extends vertically forward. A first fixed pulley is provided on the outer surface of the piston cylinder opposite to the folded portion. The rear side of the protrusion of the second installation groove on the intake pipe extends downward to form an extension portion. A second fixed pulley is provided on the front side of the extension portion. The starting end of the first pull rope is fixed to the folded portion of the outer end of the first pressing block connecting rod and extends inward, bypasses the first fixed pulley, then obliquely upward bypasses the second fixed pulley, and then extends inward to be connected to the second pressing block connecting rod.

[0018] In this way, through the setting of the two fixed pulleys, the mutual linkage between the first pressing block and the second pressing block realizes the transmission of force along the radial direction, better ensuring the stability and reliability of the action process.

[0019] Further, the first pressing block is located on the lower side surface of the piston cylinder, and the second pressing block is located on the lower side surface of the intake pipe. This is more convenient for the intake baffle to reset under the action of gravity. At the same time, it can also well avoid the interference between the air pressure linkage switch mechanism and the ammunition feeding control mechanism.

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

[0021] In this way, the length of the first pulling rope can be adjusted by tightening the adjusting device. After the length of the first pulling rope becomes shorter, the contact area between the abutting surface of the second pressing block and the air inlet baffle becomes smaller. As a result, when the piston compresses, it only needs to travel a shorter distance along the inclined surface of the first pressing block to open the air inlet baffle. When the length of the first pulling rope becomes longer, the piston needs to travel a longer distance along the inclined surface of the first pressing block to open the air inlet baffle. In this way, the stroke length of the piston when the air inlet baffle is opened can be adjusted by adjusting the length of the first pulling rope, thereby adjusting the amount of gas compression and further adjusting the ejection speed of the projectile.

[0022] Further, the tightening adjusting device includes a threaded barrel and a threaded rod that are rotatably engaged. The opposite ends of the threaded barrel and the threaded rod are connected to the first pulling rope.

[0023] This has the advantages of simple structure, convenient, fast, stable and reliable adjustment.

[0024] Further, the ammunition feeding control mechanism includes a third pressing block located at the rear upper part of the inner side wall of the piston cylinder. The third pressing block is installed in a third installation groove formed by the outward protrusion of the inner side wall of the piston cylinder. The end face of the inner end of the third pressing block is a forward inclined surface, and a third pressing block connecting rod is fixedly connected to the outer end of the third pressing block. The outer end of the third pressing block connecting rod can slide out of the piston cylinder and is connected to the rear end of a second pulling rope in a pulling manner. A third return spring sleeved on the third pressing block connecting rod is also arranged in the third installation groove. The third return spring acts on the third pressing block so that the inclined surface of its inner end just extends out of the inner groove opening of the third installation groove. The front end of the second pulling rope bypasses a pulley set arranged on the outer surface of the piston cylinder and is connected to the rear end of a horizontally arranged projectile baffle. The front half of the projectile baffle is located in the ammunition feeding port, and the rear half of the projectile baffle is located in a baffle installation groove formed by the upward protrusion of the rear half of a launch tube. The rear end of the projectile baffle can slide horizontally out of the baffle installation groove and is connected to the front end of the second pulling rope. A fourth return spring is also arranged in the baffle installation groove. The fourth return spring acts on the projectile baffle so that its front half remains in the ammunition feeding port.

[0025] In this way, during the backward movement of the piston, after reaching the rear of the piston cylinder, it contacts and presses against the inclined surface at the inner end of the third pressing block, pushing the third pressing block outwards and pulling the rear end of the second pulling rope. As a result, the projectile baffle is pulled backwards, and the front half of the projectile baffle exits the position of the ammunition inlet. At this time, the projectile in the ammunition chamber above the ammunition inlet can fall down into the launch tube, achieving ammunition feeding. In this way, the automatic ammunition feeding control effect of the projectile during the backward movement of the piston is realized. Therefore, the air pressure linkage switch mechanism and the ammunition feeding control mechanism cooperate with each other, enabling the continuous loading and automatic firing cycle of the projectile during the repeated forward and backward movement of the piston. Thus, the automatic and continuous firing of the projectile is achieved, and the planting process of plant seeds is quickly completed.

[0026] Further, the outer end of the third pressing block connecting rod is connected to the rear end of the second pulling rope through an adjusting lever. The fulcrum of the adjusting lever is hinged on a lever mounting seat protruding upwards on the front surface of the outer surface of the third installation groove. The rear end of the adjusting lever is a short arm and abuts against the outer end of the third pressing block connecting rod. The front end of the adjusting lever is a long arm and is connected to the rear end of the downwardly arranged second pulling rope.

[0027] In this way, after the third pressing block connecting rod extends outwards, the second pulling rope is pulled through the adjusting lever, which can magnify and increase the pulling distance, enabling the projectile length to be set longer to accommodate more plant seeds.

[0028] Further, in the launching device, there are multiple horizontally arranged launch tubes in parallel. The rear ends of each launch tube are connected to the same intake pipe. The front end of the second pulling rope is connected with multiple branch lines and is respectively connected to the projectile baffles at the rear parts of each launch tube.

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

[0030] Further, both the launching device and the pressure device are installed on a horizontally arranged bottom plate. The front end of the bottom plate is hinged below to a bottom plate support, and a lifting control device is arranged below the rear end of the bottom plate.

[0031] In this way, the firing direction of the launch port can be controlled and adjusted as needed.

[0032] Further, the lifting control device includes a lifting adjustment rack whose upper end is hinged below the rear end of the bottom plate. The lifting adjustment rack is slidably installed in a vertical rack guide in a vertical direction. 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. In this way, the automatic control of the lifting adjustment can be realized.

[0033] In summary, the present invention is designed according to the characteristics of riverbank slope greening. It can not only operate continuously, reduce labor costs, and achieve rapid planting of bank protection vegetation, but also overcome the limitations of steep riverbanks, reduce direct human participation, and lower the risk of manual operations.

[0039] The present invention will be further described in detail below in conjunction with the specific embodiments.

[0040] Preferred embodiment: A method for planting vegetation on riverbank slopes, characterized in that plant seeds and a nutrient matrix are mixed to form a bullet-shaped emitter, and then compressed gas is used as the power on a riverboat to launch the emitter into the soil of the riverbank slope to achieve vegetation planting.

[0041] In this way, the emitter containing plant seeds can be launched into the slope soil by the power of compressed gas, without damaging the original vegetation on the slope. At the same time, the plant seeds are embedded in the soil and are not easily washed away by the river water. After the seeds germinate, they absorb the nutrient matrix and quickly take root and grow, realizing the greening of the slope. Therefore, this method can better meet the needs of planting vegetation on riverbank slopes, especially for replanting in weak green areas, better realizing or maintaining the greening of riverbank slopes, achieving environmental greening protection, and avoiding soil erosion. During implementation, the emitter is obtained by adding plant seeds to a powdery nutrient matrix, adding a certain proportion of water to adjust it into a viscous paste material (a small amount of binder can be added if necessary to facilitate shaping), and then pressing it into a long bullet shape using a bullet-shaped die cavity mold, and then drying and curing.

[0042] Specifically, this method is realized through a riverbank slope vegetation planting device installed on a riverboat. SeeFigures 1-5 As shown, the river bank slope vegetation planting device includes a launching device located at the front end and a pressure device located at the rear end, the launching device includes a launching tube 1 arranged forward, the front end of the launching tube is a launching port forward, the rear end is connected to an air intake pipe 2 backward, a pneumatic linkage switch mechanism is installed on the air intake pipe 2, a bullet feed port is opened upward at the rear position of the launching tube 1 and a bullet compartment 3 is fixedly connected upward, the bullet compartment is used to hold a projectile 4, the projectile 4 is made of a mixture of plant seeds 5 and a nutrient matrix into a bullet shape, and a bullet feed control mechanism is also arranged at the bullet feed port of the launching tube 1; the pressure device includes a piston device connected to the air intake pipe, and the piston of the piston device is connected to a launching motor through a push-pull transmission mechanism.

[0043] In this way, when the device is used, the motor provides power to the piston device to drive the piston to move forward and backward. When the piston moves forward, the generated air pressure provides the launch pressure for the launch device. Then, the air pressure linkage switch mechanism opens the air intake pipe when the air pressure is sufficient, so that the gas pressure enters the launch tube and acts on the bullet-shaped projectile. The projectile is ejected from the launch tube by relying on the gas pressure and driven into the soil on the bank, so as to quickly and efficiently realize the planting of green plant seeds on the river bank slope. Therefore, the planting method realized based on this device overcomes the limitation of steep slope of river bank, reduces the direct participation of personnel, and reduces the risk of manual operation.

[0044] Among them, the piston device includes a piston cylinder 6, the front end 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 in the piston cylinder, and an air inlet is also arranged outward at the front end position of the circumferential side of the piston cylinder 6, and a one-way air inlet valve 8 is arranged at the air inlet.

[0045] In this way, when the piston moves forward, it can squeeze the air to generate air pressure to provide pressure for the intake pipe, until the air pressure linkage switch mechanism is opened, and the air pressure pushes the projectile forward to eject and launch. Then, during the piston's retreat, the one-way intake valve at the intake port opens to intake air, thus realizing the cycle.

[0046] Among them, the push-pull transmission mechanism includes a push-pull rod 9, the front end of the push-pull rod 9 is hinged at the middle position of the rear end of the piston 7, and the rear end of the push-pull rod 9 is eccentrically hinged on a turntable 10. The turntable 10 is rotatably mounted on the turntable base. A gear ring 11 is provided at the outer periphery of the turntable 10 and meshes with a driving gear 12. The driving gear 12 is mounted on the output shaft of the transmitting motor 13.

[0047] In this way, the output of the driving motor drives the driving gear to rotate, and then drives the turntable to rotate through the cooperation of the driving gear and the gear ring, and then drives the piston to realize the forward and backward pushing and pulling movement through the push-pull rod. Therefore, it has the advantages of simple structure, stable and reliable transmission, and the transmission ratio can be conveniently adjusted by setting the tooth number ratio of the gear ring and the driving gear. During implementation, the gear ring can be a bevel gear ring or an annular gear ring, and the driving gear is a matching bevel gear or spur gear.

[0048] Among them, the air pressure linkage switch mechanism includes a first pressing block 21 located at the front position of the inner side wall of the piston cylinder. The first pressing block 21 is located at the rear side of the one-way intake valve and is installed in a first installation groove 22 formed by the outward protrusion of the inner side wall of a piston cylinder. The end face of the inner end of the first pressing block 21 is a backward inclined plane, and a first pressing block connecting rod 23 is fixedly connected to the outer end of the first pressing block 21. The outer end of the first pressing block connecting rod 23 can slide out of the piston cylinder and is connected to a first pulling rope 24. A first return spring 25 sleeved on the first pressing block connecting rod is also arranged in the first installation groove. The first return spring 25 acts on the first pressing block to make the inclined plane of its inner end just protrude from the inner notch of the first installation groove 22. The air pressure linkage switch mechanism also includes an intake baffle 26. The intake baffle 26 is installed on an inward switch step surface formed in the transverse direction of the inner cavity of the intake pipe 2. One end of the intake baffle 26 is hinged to one side of the switch step surface, and the other end is a rotatable movable end. A second installation groove 27 protrudes outward from the inner wall of the intake pipe on the other side of the switch step surface. A second pressing block 28 is arranged in the second installation groove. The inner end of the second pressing block 28 is an abutting end, and a second pressing block connecting rod 29 is fixedly connected to the outer end of the second pressing block. The outer end of the second pressing block connecting rod 29 can slide out of the intake pipe and is connected to the front end of the first pulling rope 24. A second return spring 30 sleeved on the second pressing block connecting rod is also arranged in the second installation groove. The second return spring 30 acts on the second pressing block 28 to make its abutting end be able to block the front side of the movable end of the intake baffle.

[0049] In this way, during the forward movement of the piston, the intake baffle presses on the switch step surface and is in a closed state. The gas in the piston cylinder is gradually compressed to form a relatively large gas pressure. When the piston advances to the position of the first pressing block, it squeezes the first pressing block through the action of the inclined plane, causing the outer end of the first pressing block to protrude outward. Then, the second pressing block is pulled through the pulling rope, causing the second pressing block to be pulled and move outward, releasing the restriction on the intake baffle. The intake baffle is pushed open by the air pressure, and the air flow enters the launch tube through the intake pipe, causing the projectile to be driven by the air flow and ejected to complete the launch. After the launch is completed, during the backward movement of the piston, the suction effect generated causes the intake baffle to reset. Then, after the first pressing block loses the suppression of the piston, it resets under the action of the first return spring, releasing the tension on the first pulling rope. The second pressing block resets under the action of the second return spring and blocks the intake baffle again. One automatic firing is completed. Therefore, this structure can cleverly complete the automatic linkage between the piston and the intake baffle, enabling the intake baffle to automatically open during the forward movement of the piston, realizing the automatic control of the jet excitation.

[0050] Among them, the outer end of the first pressing block connecting rod 23 has a folded portion extending vertically forward. A first fixed pulley 31 is arranged on the outer surface of the piston cylinder opposite to the folded portion. The rear side of the protrusion of the second installation groove on the intake pipe extends downward to form an extension portion. A second fixed pulley 32 is arranged on the front side of the extension portion. The starting end of the first pulling rope 24 is fixed on the folded portion of the outer end of the first pressing block connecting rod and extends inward, bypasses the first fixed pulley 31, then obliquely upward bypasses the second fixed pulley 32, and then extends inward to be connected to the second pressing block connecting rod 29.

[0051] In this way, through the setting of the two fixed pulleys, the mutual linkage between the first pressing block and the second pressing block realizes the transmission of force along the radial direction, better ensuring the stability and reliability of the action process.

[0052] Among them, the first pressing block 21 is located on the lower side surface of the piston cylinder 6, and the second pressing block 28 is located on the lower side surface of the intake pipe 2. This is more convenient for the intake baffle to reset under the action of gravity. At the same time, it can also well avoid the interference between the air pressure linkage switch mechanism and the ammunition feeding control mechanism.

[0053] Among them, the rear side of the abutting end of the second pressing block 28 has an L-shaped abutting groove. The abutting groove has an abutting surface that can fit with a part of the front side surface of the intake baffle. The dimension of the area where the abutting surface and the intake baffle can fit along the radial direction of the intake pipe is the same as the distance that the inclined plane of the first pressing block 21 protrudes into the inner cavity of the piston cylinder. A tightening adjustment device 33 is also installed on the first pulling rope 24.

[0054] In this way, the length of the first pulling rope can be adjusted by tightening the adjusting device. After the length of the first pulling rope becomes shorter, the contact area between the abutting surface of the second pressing block and the air intake baffle becomes smaller. Furthermore, when the piston compresses, it only needs to travel a shorter distance along the inclined surface of the first pressing block to open the air intake baffle. When the length of the first pulling rope becomes longer, the piston needs to travel a longer distance along the inclined surface of the first pressing block to open the air intake baffle. In this way, the stroke length of the piston when the air intake baffle is opened can be adjusted by adjusting the length of the first pulling rope, thereby adjusting the amount of gas compression and further adjusting the ejection speed of the projectile.

[0055] Wherein, the tightening adjusting device 33 includes a threaded barrel and a threaded rod that are rotationally engaged. The opposite ends of the threaded barrel and the threaded rod are connected to the first pulling rope.

[0056] This has the advantages of simple structure, convenient, fast, stable and reliable adjustment.

[0057] Wherein, the projectile feeding control mechanism includes a third pressing block 41 located at the rear upper position of the inner side wall of the piston barrel. The third pressing block 41 is installed in a third installation groove 42 formed by the outward protrusion of the inner side wall of a piston barrel 6. The end face of the inner end of the third pressing block 41 is a forward inclined surface, and a third pressing block connecting rod 43 is fixedly connected to the outer end of the third pressing block 41. The outer end of the third pressing block connecting rod can slide out of the piston barrel and is pulled and connected to the rear end of a second pulling rope 44. A third return spring 45 sleeved on the third pressing block connecting rod is further arranged in the third installation groove. The third return spring 45 acts on the third pressing block to make the inclined surface of its inner end just protrude from the inner notch of the third installation groove 42. The front end of the second pulling rope 44 bypasses a pulley set 46 arranged on the outer surface of the piston barrel and is connected to the rear end of a horizontally arranged projectile baffle 47. The front half of the projectile baffle 47 is located in the projectile feeding port, and the rear half of the projectile baffle 47 is located in a baffle installation groove formed by the upward protrusion of the rear half of a projectile tube. The rear end of the projectile baffle can slide out of the baffle installation groove horizontally and is connected to the front end of the second pulling rope. A fourth return spring 48 is further arranged in the baffle installation groove. The fourth return spring 48 acts on the projectile baffle 47 to keep its front half in the projectile feeding port.

[0058] In this way, during the backward movement of the piston, after reaching the rear of the piston cylinder, it contacts and presses against the inclined surface at the inner end of the third pressing block, pushing the third pressing block outwards and pulling the rear end of the second pulling rope. In this way, the projectile baffle is pulled backwards, and the front half of the projectile baffle exits the position of the ammunition inlet. At this time, the projectiles in the ammunition compartment above the ammunition inlet can fall down into the launch tube, achieving ammunition feeding. In this way, the control effect of automatic ammunition feeding of the projectiles during the backward movement of the piston is achieved. Therefore, the air pressure linkage switch mechanism and the ammunition feeding control mechanism cooperate with each other, enabling the continuous loading and automatic launching cycle of the projectiles during the repeated forward and backward movement of the piston. Therefore, the automatic and continuous firing of the projectiles is achieved, and the planting process of plant seeds is quickly completed.

[0059] Among them, the outer end of the third pressing block connecting rod 43 is connected by an adjusting lever 50 and the rear end of the second pulling rope 44. The fulcrum of the adjusting lever 50 is hinged on a lever mounting seat protruding upwards on the front surface of the outer surface of the third installation groove. The rear end of the adjusting lever 50 is a short arm and abuts against the outer end of the third pressing block connecting rod 43.
