TECHNICAL FIELD

[0001] The present application relates to the technical field of urban greening engineering, in particular to a lawn seed cultivation device for urban greening engineering. BACKGROUND

[0002] Urban greening refers to the activities of improving urban ecological environment and landscape appearance by planting trees, flowers and other plants, and constructing parks, green lands, gardens, and landscape facilities such as tree-lined avenues in the urban area, which is an important part of urban construction and plays a crucial role in improving the quality of life of residents.

[0003] The patent with publication number CN212573485U relates to the technical field of urban greening, in particular to a lawn cultivation device for urban greening engineering, which aims to solve the problem of non-automatic seeding. To solve the above technical problem, the patent provides a lawn seed cultivation device for urban greening engineering, which includes a fixed disc. The design can provide seeds by inserting the feed pipe in a hopper style, then connect an external motor to the extended shaft to control rotation. The rotation of the cylindrical block will automatically enter the seeds into the inside of the barrel, and when the sliding rod enters the inside of the sliding groove C, the seeds will be automatically ejected. This design can increase the seed ejection speed by adjusting the speed of the external motor, and no matter how the position is placed, the device will not automatically drop the seeds out without being hit. By shooting and launching seeds, the seeds can be quickly placed into the soil. The device is fully automated, and it is very convenient whether it is fixed on a machine or carried by hand.

[0004] The above device is difficult to dig the soil to create a suitable seeding space for the seeds when in use. If the soil cannot be dug, the seeds may not be well buried in the soil at the appropriate depth. Seed germination usually requires close contact with the soil, because the soil can provide water and oxygen for the seeds, which affects the survival rate of the seeds. Therefore, a lawn seed cultivation device for urban greening engineering is proposed to solve the above problems. SUMMARY

[0007] Preferably, the fertilizer device includes guide plate two, triangular plate, L-shaped plate, cross fan, filter barrel, water tank, the guide plate two is fixedly connected to the right side of the guide plate one, the triangular plate is in contact with the guide plate two, the L-shaped plate is fixedly connected to the top of the triangular plate, the cross fan is in contact with the L-shaped plate, the water tank is fixedly installed on the top of the cart, the filter barrel is fixedly connected to the inner wall of the water tank, when the nutrient agent in the filter barrel enters the water tank uniformly, the consistency of the nutrient composition can be ensured every time fertilization, in modern agriculture, for large-area crop planting, it is necessary to accurately control the amount of fertilizer and fertilizer composition, if the nutrient agent cannot enter the water tank uniformly, the concentration of the nutrient solution at different positions in the water tank can be greatly different, when the nutrient solution is sprayed into the soil through the fertilizer device, the nutrients absorbed by the crops will be uneven, some areas can be over-fertilized and cause fertilizer damage, the leakage plate is fixedly connected to the inner wall of the filter barrel, the fertilizer device further includes baffle two, rotating rod two, horizontal plate, fixed plate one, stirring plate one, fixed plate two, moving plate, vertical plate, spring, the rotating rod two is fixedly connected to the top of the cross fan, the baffle two is fixedly connected to the circumference of the rotating rod two, the horizontal plate is fixedly connected to the inner wall of the water tank, the fixed plate one is fixedly connected to the top of the horizontal plate, the stirring plate one is hingedly connected to the inner wall of the fixed plate one, the moving plate is fixedly connected to the left side of the triangular plate, the fixed plate two is fixedly connected to the top of the moving plate, the vertical plate is fixedly connected to the top of the cart, the spring is fixedly connected to the right side of the moving plate, the right side of the spring is fixedly connected with the left side of the vertical plate, the inner wall of the fixed plate two is fixedly connected with the inner wall of the stirring plate one, the outer wall of the moving plate is slidably connected with the inner wall of the water tank, the circumference of the rotating rod two is rotatably connected with the inner wall of the leakage plate, the circumference of the rotating rod two is rotatably connected with the inner wall of the filter barrel, the top of the cross fan is in contact with the bottom of the filter barrel, some areas can be poorly grown due to insufficient nutrients, when the nutrient agent enters the water tank, due to the difference in factors such as density, it can not be immediately mixed with water uniformly, the stirring effect of the stirring plate one is like a stirring rod, which forms convection of the nutrient solution and water in the water tank by constantly moving, the stirring plate one moves left and right, bringing the nutrient solution with higher concentration at the bottom to the upper layer, while bringing the relatively dilute solution in the upper layer to the lower layer, so that the concentration of the solution in the entire water tank tends to be uniform, such uniform nutrient solution is very important for plants to absorb nutrients, because the plant roots can contact the nutrient solution with the same composition at different positions, avoiding the situation of local overabundance or lack of nutrients caused by uneven nutrient solution.

[0008] Preferably, the compaction device includes a trapezoidal plate, a guide plate three, a pressure plate, a T-shaped plate, a friction plate, a support plate two, rollers, a material-pulling plate two, and a reciprocating screw two. The trapezoidal plate is fixedly connected to the outer wall of the spring, the guide plate three is slidably connected to the inner wall of the trolley, and the pressure plate is fixedly connected to the bottom of the guide plate three. When the pressure plate compacts the soil on the material-pulling plate two, it first has a positive impact on the soil structure. The compacted soil particles will be more tightly packed together. When building garden paths or laying lawns, compacting the soil can reduce large pores in the soil and increase the soil density, which helps to prevent the soil from sinking during subsequent use. Correspondingly, for lawn cultivation, compacting the soil is an important step in building a stable substructure. The T-shaped plate is fixedly connected to the left side of the guide plate three, and the friction plate is fixedly connected to the T-shaped plate. On the left side, the second support plate is fixedly connected to the bottom of the trolley, the roller is in contact with the second support plate, the second reciprocating screw is fixedly connected to the rear of the roller, and the second material-feeding plate is movably connected to the circumferential surface of the second reciprocating screw. The circumferential surface of the second reciprocating screw is rotatably connected to the inner wall of the second support plate. The cross-shaped spiral groove on the second reciprocating screw drives the second material-feeding plate to move, thus covering the soil in the area where the lawn seeds have been planted. Covering the soil prevents the seeds from drying out due to rapid evaporation. Seed germination requires certain moisture conditions, and proper soil covering can reduce air flow on the soil surface, slow down the rate of water loss, and provide sufficient moisture for seed germination. In arid areas, covering the soil is particularly important for maintaining the soil moisture around the seeds, which can increase the chances of successful seed germination.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This urban greening project uses a lawn seed cultivation device. The device consists of a support plate, motor, support frame, seed bucket, rotating rod, reciprocating screw, sowing plate, rocker plate, grooved plate, guide plate, and baffle plate. The baffle plate acts as a physical divider and guide. When it moves, it pushes the tilled soil to both sides. Tilled soil is usually quite loose, making it relatively easy for the baffle plate to insert into the soil and spread it. For lawn seed sowing, this spreading of soil creates a suitable sowing space. The guide plate moves and contacts the rocker plate, causing the rocker plate to move upwards. The rocker plate's movement drives the sowing plate to rotate, spreading the seeds from the seed bucket. The primary function of this sowing device is to achieve uniform seed distribution on the soil surface. In lawn planting, if seeds are concentrated in a small area, the grass seedlings will grow too densely, competing for sunlight, water, and nutrients. Uniform sowing allows each seed sufficient space and resources to grow, resulting in a neat and uniform lawn.

[0011] 2. The lawn seed cultivation device used in this urban greening project works in conjunction with guide plate two, triangular plate, L-shaped plate, cross fan, sieve plate, baffle two, rotating rod two, filter bucket, water tank, horizontal plate, fixed plate one, feeding plate one, fixed plate two, moving plate, vertical plate, and springs. When the nutrient solution in the filter bucket enters the water tank evenly, it ensures the consistency of nutrient composition with each fertilization. In modern agriculture, for large-scale crop cultivation, precise control of fertilizer amount and composition is necessary. If the nutrient solution cannot enter the water tank evenly, it may lead to significant differences in nutrient concentration at different locations within the tank. When these nutrient solutions are sprayed onto the soil through the fertilization device, the crops will absorb nutrients unevenly, with some areas experiencing uneven absorption. Excessive nutrients may cause fertilizer burn, while insufficient nutrients may lead to poor growth in some areas. When the nutrient solution enters the water tank, it may not mix evenly with the water immediately due to differences in density and other factors. The stirring action of the feed plate acts like a stirring rod. By moving continuously, it creates convection currents between the nutrient solution and water in the water tank. The feed plate moves left and right, carrying the more concentrated nutrient solution from the bottom to the top, while carrying the relatively dilute solution from the top to the bottom, thus making the solution concentration in the entire water tank more uniform. This uniform nutrient solution is very important for plant nutrient absorption because the plant roots can come into contact with the same nutrient solution at different locations, avoiding local nutrient excess or deficiency caused by uneven nutrient solution.

[0012] 3. This urban greening project uses a lawn seed cultivation device. Through the coordinated operation of a trapezoidal plate, guide plate three, pressure plate, T-shaped plate, friction plate, support plate two, rollers, material-feeding plate two, and reciprocating screw two, the pressure plate compacts the soil on the material-feeding plate two. This first has a positive impact on the soil structure, resulting in more compacted soil particles. When building garden paths or laying lawns, compacting the soil reduces large pores and increases soil density, helping to prevent soil subsidence during subsequent use. For lawn cultivation, soil compaction is essential. A crucial step in establishing a stable underlying structure involves using the cross-shaped spiral grooves on the reciprocating screw two to move the material-pulling plate two. This movement covers the soil in the area where the lawn seeds have been planted. Covering the soil prevents the seeds from drying out due to rapid evaporation. Seed germination requires a certain level of moisture, and proper soil covering reduces airflow on the soil surface, slowing down moisture loss and providing sufficient moisture for seed germination. In arid regions, covering the soil is particularly important for maintaining soil moisture around the seeds, increasing their chances of successful germination. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-7One embodiment of the present invention is as follows: a lawn seed cultivation device for urban greening projects, comprising a cart 1, a swinging device 2 and a fertilization device 3 on the top of the cart 1, and a compaction device 4 at the bottom of the cart 1; the swinging device 2 includes a support plate 201, a motor 202, a support frame 203, a seed bucket 204, a rotating rod 205, a reciprocating screw 206, a sowing plate 207, a rocker plate 208, a grooved plate 209, a guide plate 210, and a baffle 211; the support plate 201 is fixedly connected to the front of the cart 1, the motor 202 is fixedly connected to the front of the support plate 201, the support frame 203 is fixedly connected to the top of the cart 1, and the seed bucket 204 is fixedly connected to the top of the support frame 203. Rotating rod 205 is hinged to the inner wall of support frame 203. Reciprocating screw 206 is fixedly connected to the output end of motor 202. Spreading plate 207 is fixedly connected to the circumferential surface of rotating rod 205. Tilter 208 is fixedly connected to the bottom of spreading plate 207. Groove plate 209 is movably connected to the circumferential surface of reciprocating screw 206. Guide plate 210 is fixedly connected to the top of groove plate 209. Baffle 211 is fixedly connected to the bottom of groove plate 209. When the device is started, motor 202 drives reciprocating screw 206 to rotate. The cross-shaped spiral groove on reciprocating screw 206 drives groove plate 209 to move. The movement of groove plate 209 drives baffle 306 to move and open. The movement of baffle 211 opens the soil that needs to be sown. The soil is cleared to facilitate the sowing of lawn seeds. Baffle 1 (211) acts as a physical divider and guide; as it moves, it pushes the cleared soil to both sides. The cleared soil is usually quite loose, making it relatively easy for baffle 2 (306) to insert and clear the soil. For lawn seed sowing, this clearing creates a suitable sowing space. Lawn seeds are generally small and need to be relatively evenly distributed in the soil at a certain depth for better germination and growth. After baffle 2 (306) clears the soil, the seeds can be placed in the cleared space. The depth and width of this space can be determined according to the design dimensions and movement method of baffle 2 (306). The circumference of reciprocating screw 1 (206) and... The inner wall of the support plate 201 is rotatably connected, and the outer wall of the grooved plate 209 is slidably connected to the inner wall of the trolley 1. The movement of the grooved plate 209 drives the guide plate 210 to move. The guide plate 210 moves and contacts the rocker 208, causing the rocker 208 to move upward. The movement of the rocker 208 drives the sowing plate 207 to rotate, sowing the seeds in the seed bucket 204. The main function of the seed bucket 204 in sowing the seeds is to achieve a uniform distribution of the seeds on the soil surface. In lawn planting, if the seeds are concentrated in a small area, the grass seedlings in that area will grow too densely and compete for sunlight, water and nutrients. Uniform sowing allows each seed to have enough space and resources to grow, thus forming a neat and uniform lawn.

[0023] The fertilizer applicator 3 includes a second guide plate 301, a triangular plate 302, an L-shaped plate 303, a cross fan 304, a strainer 305, a filter bucket 308, and a water tank 309. The second guide plate 301 is fixedly connected to the right side of the first guide plate 210. The triangular plate 302 contacts the second guide plate 301. The L-shaped plate 303 is fixedly connected to the top of the triangular plate 302. The cross fan 304 contacts the L-shaped plate 303. The water tank 309 is fixedly installed on the top of the trolley 1. The filter bucket 308 is fixedly connected to the inner wall of the water tank 309. Moving the first guide plate 210 moves the second guide plate 301, which in turn moves the triangular plate 302. The triangular plate 302 then moves the L-shaped plate 303, which in turn moves the cross fan. Contact at 304 causes the cross-shaped fan 304 to rotate, which in turn drives the rotating rod 307 to rotate. The rotating rod 307 then drives the baffle 306 to rotate. Through the holes in the filter barrel 308 and the perforated plate 305, the nutrients inside the filter barrel 308 are evenly distributed into the water tank 309. This even distribution ensures consistency of nutrient composition during each fertilization. In modern agriculture, large-scale crop cultivation requires precise control of fertilizer application and composition. If the nutrients cannot evenly distribute into the water tank 309, significant differences in nutrient solution concentration may occur at different locations within the tank. When these nutrient solutions are sprayed onto the soil through the fertilization device 3... Uneven nutrient absorption by crops can lead to fertilizer burn in some areas and poor growth in others due to insufficient nutrients. Nutrients evenly introduced into water tank 309 can be formulated into a stable concentration of nutrient solution, ensuring a balanced nutrient supply to the entire growth area, thus stabilizing growth and increasing yield. The sluice plate 305 is fixedly connected to the inner wall of the filter tank 308. The fertilization device 3 also includes a second baffle 306, a second rotating rod 307, a horizontal plate 310, a first fixed plate 311, a first feeding plate 312, a second fixed plate 313, a moving plate 314, a vertical plate 315, and a spring 316. The second rotating rod 307 is fixedly connected to the top of the cross fan 304, and the second baffle 306 is fixedly connected to the second rotating rod 306. The circumferential surface of the rotating rod 307 is as follows: horizontal plate 310 is fixedly connected to the inner wall of water tank 309; fixed plate 311 is fixedly connected to the top of horizontal plate 310; material feeding plate 312 is hinged to the inner wall of fixed plate 311; moving plate 314 is fixedly connected to the left side of triangular plate 302; fixed plate 313 is fixedly connected to the top of moving plate 314; vertical plate 315 is fixedly connected to the top of trolley 1; spring 316 is fixedly connected to the right side of moving plate 314; the right side of spring 316 is fixedly connected to the left side of vertical plate 315; the inner wall of fixed plate 313 is fixedly connected to the inner wall of material feeding plate 312; the outer wall of moving plate 314 is slidably connected to the inner wall of water tank 309; and the circumferential surface of rotating rod 307 is rotatably connected to the inner wall of drain plate 305.The circumferential surface of the rotating rod 307 is rotatably connected to the inner wall of the filter barrel 308. The top of the cross fan 304 contacts the bottom of the filter barrel 308. The movement of the moving plate 314 drives the movement of the fixed plate 313, which in turn drives the movement of the feeding plate 312. The movement of the feeding plate 312 ensures that the nutrient solution is fully mixed with the water inside the water tank 309. The spring 316 resets the device. The movement of the feeding plate 312 can break up any possible stratification between the nutrient solution and the water. When the nutrient solution enters the water tank 309, due to differences in density and other factors, it may not immediately separate. The nutrient solution and water are evenly mixed. The stirring action of the feed plate 312 acts like a stirring rod. Through continuous movement, it creates convection currents between the nutrient solution and water within the water tank 309. The feed plate 312 moves left and right, carrying the more concentrated nutrient solution from the bottom to the top, while simultaneously carrying the relatively dilute solution from the top to the bottom. This ensures a uniform solution concentration throughout the water tank 309. This uniform nutrient solution is crucial for plant nutrient absorption because it ensures that plant roots at different locations can access the same composition of nutrient solution, preventing localized nutrient overload or deficiency caused by uneven nutrient distribution.

[0024] Working Principle: When the device is started, motor 202 drives reciprocating screw 206 to rotate. The cross-shaped spiral grooves on reciprocating screw 206 move grooved plate 209, which in turn moves baffle 306 to open. Baffle 211 then moves to separate the tilled soil, facilitating the sowing of lawn seeds. Baffle 211 acts as a physical divider and guide; as it moves, it pushes the tilled soil to both sides. Tilled soil is usually quite loose, making it relatively easy for baffle 306 to insert into the soil and perform the spreading operation. For lawn seed sowing, this soil-spreading operation creates a suitable sowing space. Lawn seeds are generally small and need to be relatively evenly distributed in the soil at a certain depth for better germination and growth. After the soil is cleared by plate 2 306, the seeds can be placed in the cleared space. The depth and width of this space can be determined according to the design dimensions and movement method of plate 2 306. The movement of the groove plate 209 drives the movement of the guide plate 1 210. The guide plate 1 210 moves and contacts the rocker plate 208, causing the rocker plate 208 to move upward. The movement of the rocker plate 208 drives the sowing plate 207 to rotate, sowing the seeds in the seed bucket 204. The main function of the seed bucket 204 in sowing the seeds is to achieve a uniform distribution of the seeds on the soil surface. In lawn planting, if the seeds are concentrated in a small area, the grass seedlings in that area will grow too densely and compete for sunlight, water and nutrients. Uniform sowing allows each seed to have enough space and resources to grow, thus forming a neat and uniform lawn.

[0025] The movement of guide plate 210 drives guide plate 301 to move, which in turn drives triangular plate 302 to move, which in turn drives L-shaped plate 303 to move. L-shaped plate 303 then contacts cross fan 304, causing cross fan 304 to rotate. The rotation of cross fan 304 drives rotating rod 307 to rotate, which in turn drives baffle 306 to rotate. Through the holes in the filter plate 305 and filter tank 308, the nutrients inside filter tank 308 are evenly introduced into the water tank 309. When the nutrient solution is evenly distributed inside the water tank 309, it ensures the consistency of nutrient composition with each application. In modern agriculture, large-scale crop cultivation requires precise control of fertilizer application and composition. If the nutrient solution cannot be evenly distributed within the water tank 309, significant differences in nutrient concentration may occur at different locations. When these nutrient solutions are sprayed into the soil through the fertilization device 3, the crops will absorb nutrients unevenly. Some areas may suffer from fertilizer burn due to excessive nutrients, while others may experience poor growth due to insufficient nutrients. Evenly distributing the nutrient solution within the water tank 309 ensures consistent nutrient composition. A stable concentration of nutrient solution is prepared to ensure a balanced nutrient supply to crops throughout their growth zone, thereby stabilizing growth and increasing yield. The movement of the movable plate 314 moves the fixed plate 313, which in turn moves the feeding plate 312. The movement of the feeding plate 312 ensures the nutrient solution fully mixes with the water in the water tank 309. A spring 316 resets the device. The movement of the feeding plate 312 breaks up any possible stratification between the nutrient solution and water. When the nutrient solution enters the water tank 309, due to differences in density and other factors, it may not immediately separate. The nutrient solution is evenly mixed with water. The stirring action of the feed plate 312 is like a stirring rod. By constantly moving, it creates convection between the nutrient solution and water in the water tank 309. The feed plate 312 moves left and right, bringing the higher concentration of nutrient solution from the bottom to the upper layer, while bringing the relatively dilute solution from the upper layer to the lower layer. This makes the concentration of the solution in the entire water tank 309 more uniform. This uniform nutrient solution is very important for plant nutrient absorption because the plant roots can come into contact with the same composition of nutrient solution at different locations, avoiding local nutrient excess or deficiency caused by uneven nutrient solution.

[0026] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the compaction device 4 includes a trapezoidal plate 401, a guide plate 402, a pressure plate 403, a T-shaped plate 404, a friction plate 405, a support plate 406, a roller 407, a feed plate 408, and a reciprocating screw 409. The trapezoidal plate 401 is fixedly connected to the outer wall of the spring 316, the guide plate 402 is slidably connected to the inner wall of the trolley 1, and the pressure plate 403 is fixedly connected to the bottom of the guide plate 402. The trapezoidal plate 401 is moved by the extension and retraction of the spring 316, and the guide plate 402 is moved downward by the inclined surface on the trapezoidal plate 401. The downward movement of plate 402 causes plate 403 to move, compacting the soil on plate 408. This compaction positively impacts the soil structure, as the compacted soil particles are more tightly packed together. When building garden paths or laying lawns, compaction reduces large pores and increases soil density, helping to prevent subsidence during subsequent use. For lawn cultivation, compaction is a crucial step in building a stable substructure. T-plate 404 is fixedly connected to guide plate 402. On the left side of 02, friction plate 405 is fixedly connected to the left side of T-plate 404, support plate 406 is fixedly connected to the bottom of trolley 1, roller 407 contacts support plate 406, reciprocating screw 409 is fixedly connected to the rear of roller 407, and feed plate 408 is movably connected to the circumferential surface of reciprocating screw 409. The circumferential surface of reciprocating screw 409 is rotatably connected to the inner wall of support plate 406. The movement of guide plate 402 drives T-plate 404 to move, and the movement of T-plate 404 drives friction plate 405 to move. Friction plate 405 moves and contacts roller 407, causing roller 407 to rotate. 07 rotates, driving the reciprocating screw 409 to rotate. The cross-shaped spiral groove on the reciprocating screw 409 drives the material feeding plate 408 to move, covering the soil in the area where the lawn seeds have been planted. Covering the soil prevents the seeds from drying out due to rapid evaporation. Seed germination requires a certain amount of moisture. Appropriate soil covering can reduce air movement on the soil surface, slow down the rate of moisture loss, and provide sufficient moisture for seed germination. In arid areas, covering the soil is particularly important for maintaining soil moisture around the seeds, increasing the chances of successful germination.

[0027] Working Principle: The spring 316 extends and retracts, driving the trapezoidal plate 401 to move. The inclined surface of the trapezoidal plate 401 then moves the guide plate 402 downwards. The downward movement of the guide plate 402 moves the pressure plate 403, which in turn compacts the soil on the material-dispensing plate 408. This compaction positively impacts the soil structure, resulting in more tightly packed soil particles. When building garden paths or laying lawns, compacting the soil reduces large pores and increases soil density, helping to prevent subsidence during subsequent use. For lawn cultivation, compacting the soil is a crucial step in building a stable substructure. The movement of the guide plate 402 drives the T-shaped... The movement of plate 404, the movement of T-plate 404 drives the movement of friction plate 405, and the movement of friction plate 405 contacts roller 407, causing roller 407 to rotate. The rotation of roller 407 drives reciprocating screw 2 409 to rotate, and through the cross-shaped spiral groove on reciprocating screw 2 409, it drives material feeding plate 2 408 to move, causing material feeding plate 2 408 to move and cover the soil on the area where the lawn seeds have been planted. Soil covering prevents the seeds from drying out due to rapid water evaporation. Seed germination requires certain moisture conditions, and appropriate soil covering can reduce air flow on the soil surface, slow down the rate of water loss, and provide sufficient moisture for seed germination. In arid areas, the action of covering the soil is particularly important for maintaining the soil moisture around the seeds, which can increase the chances of successful seed germination.
