Description

Technical Field

[0001] This invention relates to the field of hydroseeding technology for slope greening, specifically to a mixing device for hydroseeding substrates for slope greening. Background Technology

[0002] After slope construction is completed, in order to reduce soil erosion and improve slope greening, hydroseeding is usually used. This involves spraying a slurry containing grass seeds, humus, soil, and fertilizer onto the slope. This allows for rapid grass seeding, fertilization, and irrigation, facilitating quick germination of the grass seeds and ensuring rapid greening of the slope. During hydroseeding, the grass seeds, humus, soil, and fertilizer must be thoroughly mixed using a mixing device to ensure that the ratio of grass seeds, fertilizer, and water in the slurry is appropriate.

[0003] Existing hydroseeding substrate mixing devices can only use a relatively simple mixing frame and motor drive to mix the hydroseeding substrate. This makes it difficult to remove long, incompletely decomposed straw from the humus, and also cannot remove metal fragments and stones from the hydroseeding substrate. As a result, metal fragments, large stones, and long straw that enter the mixing device along with the grass seeds, humus, soil, and fertilizer will affect subsequent hydroseeding work, block and damage pumps and other facilities in the hydroseeding equipment, and disrupt the normal operation of hydroseeding.

Detailed Implementation

[0019] 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. Example

[0020] Please see Figure 1-6 A mixing device for spraying substrate for slope greening includes a tank 1, a sealing cover 2 on the top of the tank 1, and a rejection mechanism 3 on the outside of the tank 1. The rejection mechanism 3 includes a rotating rod 301, which is rotatably connected to the inside of the tank 1. A filter plate 302 is fixedly connected to the inner wall of the tank 1. The rotating rod 301 is rotatably connected to the inside of the filter plate 302. Three fixed shells 303 are fixedly connected to the inner wall of the filter plate 302. A rectangular permanent magnet 304 is fixedly connected to the inner wall of each fixed shell 303. Three arc-shaped frames 305 are fixedly connected to the outer surface of the rotating rod 301. An arc-shaped scraper 306 is provided below each arc-shaped frame 305. The bottom surface of each of the three arc-shaped scrapers 306 is in contact with the upper surface of the filter plate 302. Several telescopic cylinders 307 are fixedly connected to the bottom surface of each arc-shaped frame 305. A telescopic column 308 is slidably connected inside each telescopic cylinder 307. The bottom end of each telescopic column 308 is fixedly connected to the upper surface of the arc-shaped scraper 306. A compression spring 309 is fixedly connected to the inner top wall of each telescopic cylinder 307. The bottom end of each compression spring 309 is fixedly connected to the top end of the telescopic column 308. Three collection racks 3 are fixedly connected to the outer surface of the tank body 1. 10. Each collection rack 310 is equipped with a filter plate 302 above it. Each collection rack 310 has a slidably connected sealing plate 311 inside. Each sealing plate 311 has rubber sealing gaskets 312 fixedly connected to both sides. Each collection rack 310 has a screw 313 rotatably connected inside. The outer surface of each screw 313 is threadedly connected to the sealing plate 311. By setting the removal mechanism 3, incompletely decomposed long straw, large metal fragments, stones and other impurities can be removed during the mixing process of the slope greening spraying substrate. This makes the particle size of the slope greening spraying substrate more uniform and fine after mixing. It can also collect the removed long straw, large metal fragments and large stones for subsequent processing, thereby improving the mixing quality of the slope greening spraying substrate. This prevents long straw, large metal fragments and large stones from clogging and damaging the pump and other facilities in the spraying equipment during subsequent slope greening spraying work, effectively increasing the performance of the slope greening spraying substrate mixing equipment.

[0021] The bottom surface of the tank body 1 is fixedly connected with three support legs 314. Each support leg 314 is fixedly connected to a mounting flange 315 at its bottom end. Each mounting flange 315 has several mounting through holes 316 on its upper surface. The support legs 314 can support the device and, together with the mounting flanges 315 and mounting through holes 316, can be fixed in the working position using bolts and other fasteners, thereby increasing the reliability and stability of the tank body 1.

[0022] Both the outer surface of the sealing cap 2 and the outer surface of the tank body 1 are fixedly connected to a connecting plate 317. The common thread of the two connecting plates 317 is connected to several mounting bolts 318. The bottom ends of the mounting bolts 318 all penetrate to the bottom of the two connecting plates 317. By cooperating with the mounting bolts 318, the connection tightness between the sealing cap 2 and the tank body 1 can be increased, making it less likely for the connection between the sealing cap 2 and the tank body 1 to loosen.

[0023] The upper surface of the sealing cover 2 is fixedly connected to two feeding pipes 319, and the bottom surface of the tank body 1 is fixedly connected to a discharge valve 320. Using the two feeding pipes 319, workers can easily put water, grass seeds, humus, soil and fertilizer into the tank body 1 for mixing. The discharge valve 320 allows workers to easily discharge the mixed slope greening spraying substrate slurry outward, ensuring the normal operation of the tank body 1 for feeding and discharging.

[0024] A stabilizing base 321 is fixedly connected to the upper surface of the sealing cover 2. A servo motor 322 is fixedly connected to one side of the stabilizing base 321. The output end of the servo motor 322 passes through the sealing cover 2 and is fixedly connected to the top of the rotating rod 301. With the power provided by the servo motor 322 and the fixation of the stabilizing base 321, the rotating rod 301 can be driven to rotate, thereby ensuring that the rotating rod 301 can smoothly drive the arc frame 305 and the arc scraper 306 to rotate.

[0025] Two sets of first mixing frames 323 are fixedly connected to the outer surface of the rotating rod 301. Each set of first mixing frames 323 consists of three units. One set of first mixing frames 323 is located above the filter plate 302. Three second mixing frames 324 are fixedly connected to the outer surface of the rotating rod 301. The first mixing frames 323 can mix the sprayed substrate both when the filter plate 302 is not filtering it and after the filter plate 302 has filtered it. The second mixing frames 324 can further improve the mixing effect of the slope greening sprayed substrate, ensuring that the slope greening sprayed substrate can be fully mixed.

[0026] Each screw 313 has a limit frame 325 rotatably connected to its outer surface. The bottom surface of each limit frame 325 is fixedly connected to the upper surface of the collection frame 310. The limit frame 325 can limit the upward movement distance of the sealing plate 311, prevent the sealing plate 311 from detaching from the collection frame 310, and also increase the stability and reliability of the screw 313 rotation.

[0027] The specific implementation method of this embodiment is as follows: In use, the servo motor 322 is first connected to the external power supply and the controller. When it is necessary to mix the substrate for slope greening spraying, water, grass seeds, humus, soil, and fertilizer are first added into the tank 1 using two feeding pipes 319. Since the filter holes on the filter plate 302 are small, with a five-mesh aperture of four millimeters, the water and substrate will temporarily remain on the filter plate 302 after entering the tank 1, and then gradually penetrate downwards through the filter plate 302. Since slope greening usually uses No. 2 grass seeds with a fast germination rate and rapid growth (three millimeters in diameter), the grass seeds can smoothly pass through the filter plate 302 and enter the tank 1. Then, the servo motor 322, in conjunction with the stabilizing base 321, drives the rotating rod 301, the first mixing frame 323, and the second mixing frame 324 to rotate, thus mixing the slope greening spraying substrate. Larger soil particles remaining on the filter plate 302 are broken up by the first mixing frame 323 located above the filter plate 302 and ultimately mixed into the slope greening spraying substrate slurry. Larger metal fragments, stones, and longer, unmixable straw remain above the filter plate 302. Meanwhile, metal blocks that can pass through the filter plate 302 are attracted by the rectangular permanent magnet 304 and the fixing shell 303, preventing larger metal fragments, stones, and other debris from being dispersed. The shredded, longer straws enter the tank 1, making the particle size of the slope greening spraying substrate more uniform and fine after mixing. This improves the mixing quality of the slope greening spraying substrate, preventing the pump and other facilities in the spraying equipment from being blocked or damaged by longer straws, larger metal fragments, and larger stones during subsequent slope greening spraying work. This effectively increases the performance of the slope greening spraying substrate mixing equipment. At this time, the rotating rod 301 drives the arc frame 305 to rotate, which in turn drives the arc scraper 306 to rotate. Under the cooperation of the telescopic cylinder 307, telescopic column 308, and compression spring 309, the arc scraper 306 can closely adhere to the upper surface of the filter plate 302, thereby utilizing the arc... The rotation and arc shape of the curved scraper 306 can scrape away larger metal fragments, stones, and long straws on the filter plate 302, as well as small metal blocks attracted by the rectangular permanent magnet 304, preventing the filter plate 302 from being blocked. At the same time, the larger metal fragments, stones, long straws, and small metal blocks attracted by the rectangular permanent magnet 304 are pushed into the collection rack 310 as the curved scraper 306 rotates. When it is necessary to clean the impurities inside the collection rack 310, simply rotate the screw 313 in conjunction with the limit frame 325, which can drive the sealing plate 311 and the rubber sealing gasket 312 to move upward, opening the collection rack 310, making it convenient for staff to collect and process the impurities inside. Example

[0028] Please see Figure 2 , Figure 3 , Figures 7-9 Below the rejection mechanism 3, a magnetic attraction mechanism 4 is provided. The magnetic attraction mechanism 4 includes two filter cylinders 401. The sides of the two filter cylinders 401 that are far apart from each other are fixedly connected to the inner wall of the tank body 1. A rotating cylinder 402 is provided inside each of the two filter cylinders 401. The two rotating cylinders 402 are rotatably connected to the inside of the tank body 1. A positioning cylinder 403 is rotatably connected to the outer surface of each of the two rotating cylinders 402. The opposite sides of the two positioning cylinders 403 are fixedly connected to the outer surface of the tank body 1. A sealing bearing 419 is fixedly embedded inside each of the two positioning cylinders 403. The inner walls of the inner rings of the two sealing bearings 419 are respectively fixedly connected to the outer surfaces of the two rotating cylinders 402. 02. A first gear 404 is fixedly connected to each of the two ends of the rotating rod 301, which are far apart from each other. Two transmission rods 405 are rotatably connected inside the tank body 1. A first bevel gear 406 is fixedly connected to one end of each transmission rod 405. A second bevel gear 407 is fixedly connected to the outer surface of the rotating rod 301. Both first bevel gears 406 mesh with the second bevel gears 407. The other ends of the two transmission rods 405 pass through the tank body 1 and are fixedly connected to a second gear 408. The two second gears 408 mesh with the two first gears 404 respectively. A semi-circular permanent magnet 409 is installed inside each of the two rotating cylinders 402. A scraping frame 410 is installed below each of the two rotating cylinders 402. The upper surfaces of both scraping frames 410 are in contact with the outer surface of the rotating cylinder 402. A collection groove 411 is provided on the back of each of the two scraping frames 410. A fixed cylinder 412 is fixedly connected to the bottom surface of each of the two scraping frames 410. The ends of the two fixed cylinders 412 that are far apart from each other extend to the outside of the tank body 1. The inner walls of the two fixed cylinders 412 are fixedly connected to the inner wall of the tank body 1. A screw frame 413 is rotatably connected inside each of the two fixed cylinders 412. One end of each screw frame 413 passes through the fixed cylinder 412 and the tank body 1 and is fixedly connected to a third gear 414. The two third gears 414 are respectively meshed with two first gears 404. The outer surfaces of the two fixed cylinders 412... The surface is fixedly connected to a collection cylinder 415. The inside of each collection cylinder 415 is threadedly connected to a disassembly cylinder 416. By setting a magnetic attraction mechanism 4, the attraction force provided by the semi-circular permanent magnet 409 can be used to adsorb and collect the tiny metal particles in the spraying substrate mixed mud that have not been filtered out by the filter plate 302. This makes the metal particles in the spraying substrate mixed mud less, preventing excessive metal particles in the spraying substrate mixed mud from causing excessive wear on the pipes and pumps in the high-pressure spraying equipment and affecting their service life. This not only further increases the purity of the slope greening spraying substrate mixed mud, but also further improves the mixing quality of the slope greening spraying substrate mixing device.

[0029] Both transmission rods 405 are rotatably connected to limit sealing rings 417 on their outer surfaces. The opposite sides of the two limit sealing rings 417 are fixedly connected to the outer surface of the tank body 1. The limit sealing rings 417 can further stabilize the position of the transmission rods 405 and seal the connection between the transmission rods 405 and the tank body 1 to prevent liquid from leaking through gaps and increase the tightness of the fit between the transmission rods 405 and the tank body 1.

[0030] The outer surfaces of the two transmission rods 405 and the outer surface of the rotating rod 301 are rotatably connected to a protective shell 418. The two first bevel gears 406 and the second bevel gear 407 are both located inside the protective shell 418. The protective shell 418 can protect the meshing of the first bevel gears 406 and the second bevel gear 407 without affecting the normal rotation of the transmission rods 405 and the rotating rod 301, and prevent impurities from causing the first bevel gears 406 and the second bevel gear 407 to jam.

[0031] Each of the two semicircular permanent magnets 409 has a fixed bracket 420 fixedly connected to one end of each of the two fixed brackets 420. One side of each fixed bracket 420 is fixedly connected to one side of each of the two positioning cylinders 403. The fixed bracket 420 can fix and position the semicircular permanent magnets 409 inside the rotating cylinder 402 without affecting the rotation of the rotating cylinder 402, so that the semicircular permanent magnets 409 can always provide stable magnetic force in a fixed position.

[0032] The specific implementation of this embodiment is as follows: When the slope greening spraying substrate slurry enters the tank 1 through the filter plate 302, the filter hole diameter of the filter cylinder 401 is two millimeters, which is smaller than the three-millimeter diameter of the No. 2 grass seed. Therefore, the grass seed cannot enter the filter cylinder 401. The tiny metal particles that are not filtered out by the filter plate 302 are attracted by the attraction provided by the semi-circular permanent magnet 409, pass through the filter cylinder 401 and are adsorbed on the outside of the rotating cylinder 402. At this time, with the rotation of the rotating rod 301, the protective shell 418 and the meshing of the first bevel gear 406 and the second bevel gear 407 can drive the transmission rod 405 and the second gear 408 to rotate. Thus, the first gear 404, with the assistance of the positioning cylinder 403 and the sealed bearing 419, drives the rotating cylinder 402 to rotate. When the rotating cylinder 402 rotates, it can drive the metal particles adsorbed on the rotating cylinder 402 to move and enter the scraper 410 through the collection groove 411 and be scraped off by the scraper 410. When the metal particles come into contact with the scraper 410, they have moved away from the semi-circular permanent magnet 409, allowing them to detach from the rotating cylinder 402 and enter the fixed cylinder 412 through the scraper 410. This reduces the amount of metal particles in the sprayed substrate mixture, preventing excessive wear on the pipes and pumps in the high-pressure spraying equipment and extending their service life. This not only further increases the purity of the slope greening sprayed substrate mixture but also improves the mixing quality of the slope greening sprayed substrate mixing device. When the first gear 404 rotates, it drives the screw frame 413 to rotate via the third gear 414. The rotation of the screw frame 413 then sends the metal particles inside the fixed cylinder 412 into the collection cylinder 415. When it is necessary to clean the metal particles inside the collection cylinder 415, simply rotate the disassembly cylinder 416 to unscrew it from the collection cylinder 415 to remove the metal particles.

[0033] The working principle of this invention is as follows: In use, the servo motor 322 is first connected to an external power supply and controller. When it is necessary to mix the substrate for slope greening spraying, water, grass seeds, humus, soil, and fertilizer are first added into the tank 1 using two feeding pipes 319. Because the filter holes on the filter plate 302 are small (five mesh, four millimeters in diameter), the water and substrate will temporarily remain on the filter plate 302 after entering the tank 1, and then gradually permeate downwards through the filter plate 302. Since slope greening typically uses No. 2 grass seeds with a fast germination rate and rapid growth (three millimeters in diameter), the grass seeds can smoothly pass through the filter plate 302 and enter the tank 1. The servo motor 322, in conjunction with the stabilizing base 321, drives the rotating rod 301 and the first mixing frame 323 and the second mixing frame 324 to rotate, thus mixing the slope greening spraying substrate. Larger soil particles remaining on the filter plate 302 are broken up by the first mixing frame 323 located above the filter plate 302 and ultimately mixed into the slope greening spraying substrate slurry. Larger metal fragments, stones, and long, unmixable straw remain above the filter plate 302. Meanwhile, metal blocks that can pass through the filter plate 302 are attracted by the rectangular permanent magnet 304 and the fixing shell 303, preventing larger metal fragments, stones, and unmixable materials from being removed. Longer straws enter the tank 1, making the particle size of the slope greening spraying substrate more uniform and fine after mixing. This improves the mixing quality of the slope greening spraying substrate and prevents the pump and other facilities in the spraying equipment from being blocked or damaged by longer straws, larger metal fragments, and larger stones during subsequent slope greening spraying work. This effectively increases the performance of the slope greening spraying substrate mixing equipment. At this time, the rotating rod 301 drives the arc frame 305 to rotate, which in turn drives the arc scraper 306 to rotate. Under the cooperation of the telescopic cylinder 307, telescopic column 308, and compression spring 309, the arc scraper 306 can stick tightly to the upper surface of the filter plate 302, thereby utilizing the arc shape... The rotation and arc shape of the scraper 306 can scrape away larger metal fragments, stones, and long straws on the filter plate 302, as well as small metal blocks attracted by the rectangular permanent magnet 304, preventing the filter plate 302 from being blocked. At the same time, the larger metal fragments, stones, and long straws, as well as small metal blocks attracted by the rectangular permanent magnet 304, are pushed into the collection rack 310 as the arc-shaped scraper 306 rotates. When it is necessary to clean the impurities inside the collection rack 310, simply rotate the screw 313 in conjunction with the limit frame 325, which can drive the sealing plate 311 and the rubber sealing gasket 312 to move upward, opening the collection rack 310, making it convenient for staff to collect and process the impurities inside. When the slope greening spraying substrate slurry enters the tank 1 through the filter plate 302, the filter cylinder 401 has a filter hole diameter of two millimeters, which is smaller than the three-millimeter diameter of the No. 2 grass seed. Therefore, the grass seed cannot enter the filter cylinder 401. The tiny metal particles that are not filtered out by the filter plate 302 are attracted by the attraction provided by the semi-circular permanent magnet 409, pass through the filter cylinder 401, and are adsorbed on the outside of the rotating cylinder 402. At this time, with the rotation of the rotating rod 301, the protective shell 418 and the meshing of the first bevel gear 406 and the second bevel gear 407 can drive the transmission rod 405 and the second gear 408 to rotate. Thus, with the assistance of the first gear 404, the positioning cylinder 403 and the sealed bearing 419, the rotating cylinder 402 is driven to rotate. When the rotating cylinder 402 rotates, it can move the metal particles adsorbed on the rotating cylinder 402 and enter the scraper 410 through the collection groove 411 to be scraped off by the scraper 410. Because the rotating cylinder 402 moves the metal particles, the metal particles are removed. When the metal particles come into contact with the scraper 410, they have moved away from the semi-circular permanent magnet 409, allowing them to detach from the rotating cylinder 402 and enter the fixed cylinder 412 through the scraper 410. This reduces the amount of metal particles in the sprayed substrate mixture, preventing excessive metal particles from causing excessive wear on the pipes and pumps in the high-pressure spraying equipment and affecting their service life. This not only further increases the purity of the slope greening sprayed substrate mixture but also improves the mixing quality of the slope greening sprayed substrate mixing device. When the first gear 404 rotates, it drives the screw frame 413 to rotate through the third gear 414. The rotation of the screw frame 413 helps to send the metal particles inside the fixed cylinder 412 into the collection cylinder 415. When it is necessary to clean the metal particles inside the collection cylinder 415, simply rotate the disassembly cylinder 416 to unscrew it from the collection cylinder 415 to clean the metal particles.
