Detailed Implementation

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0020] Please see Figure 1 The soil spraying and greening device of this utility model includes a towable vehicle 20, which consists of a towable chassis and wheels. It can be towed and moved by manpower or small machinery at the construction site, improving the flexibility of use and meeting the construction requirements in scenarios with limited accessibility.

[0021] A generator 22 and a base 19 are mounted on a towable vehicle 20. A seed slurry tank 11 is mounted on the base 19 and supported by a tank bracket 13. The seed slurry tank 11 has a conical bottom 12. The generator 22 is used to generate electricity on site to provide power for the operation of this hydroseeding greening device. The seed slurry tank 11 stores seed slurry, which is made by mixing peat moss, wood fiber (or pulp), water-absorbing resin, nutrient soil, water and other materials in a certain proportion to form a topsoil substrate with good adhesion and water retention. Plant seeds are mixed in the topsoil substrate. The seed slurry has a certain degree of fluidity.

[0022] In this embodiment, two stirring assemblies 10 are installed inside the seed pulp tank 11. The stirring assembly 10 includes a stirring motor installed on the top wall of the seed pulp tank 11, a stirring shaft located inside the seed pulp tank 11, and a stirring impeller located at the lower end of the stirring shaft. The stirring impeller of one stirring assembly 10 is located in the middle of the inner cavity of the seed pulp tank 11, and the stirring impeller of the other stirring assembly 10 is located at the bottom of the inner cavity of the seed pulp tank 11.

[0023] like Figure 1 As shown, a covered opening 9 is provided on the top of the seed slurry tank 11. Before the spraying construction, the seed slurry is injected into the tank through the opening 9. Two mixing components 10 operate continuously during the topsoil spraying construction to continuously stir the seed slurry in the seed slurry tank 11 and maintain the uniformity of the seed slurry.

[0024] A slurry discharge assembly 14 and a slurry discharge motor 16 are installed at the bottom of the conical bottom 12. A guide pipe assembly 15 is installed at the outlet of the slurry discharge assembly 14. The guide pipe assembly 15 includes a conical pipe 15-1 with open front and rear ends. A baffle 15-2 is installed in the middle of the inner cavity of the conical pipe 15-1. The slurry discharge assembly 14 discharges the seed slurry in the seed slurry tank 11 into the space above the conical pipe 15-1 and the baffle 15-2. The external airflow enters through the channel below the baffle 15-2.

[0025] Please see Figure 2 and Figure 3 It can be seen that:

[0026] The pulp discharge assembly 14 includes a pulp discharge housing 14-1, inside which a pulp discharge roller 14-3 is installed. Multiple seed pulp grooves are provided on the side wall of the pulp discharge roller 14-3. A drive wheel 14-2 is installed at the end of the shaft of the pulp discharge roller 14-3, and the drive wheel 14-2 is driven to rotate by a pulp discharge motor 16. The pulp discharge motor 16 drives the pulp discharge roller 14-3 to rotate. When the seed pulp groove rotates to the upper position, the seed pulp enters the groove. As the seed pulp groove rotates to the lower position, the seed pulp in the groove flows downward into the conical tube 15-1.

[0027] It also includes an adapter 23 with a slurry discharge channel. The adapter 23 is fixedly connected to the top of the slurry discharge housing 14-1 of the slurry discharge assembly 14. The upper end of the slurry discharge channel is connected to the slurry outlet on the conical bottom 12. The adapter 23 is also used as a fixing seat for the slurry discharge assembly 14. That is, the slurry discharge assembly 14 is combined with the seed pulp tank 11 and its conical bottom 12 to form a whole through the adapter 23.

[0028] In this embodiment, the drive wheel 14-2 is a sprocket, and another sprocket is mounted on the output shaft of the pulp discharge motor 16. The two sprockets are connected by chain drive. Figure 1 As shown, a motor bracket 17 is mounted on the base 19, and the pulp discharge motor 16 is mounted and fixed on the motor bracket 17.

[0029] An inclined nozzle 1 is installed at the front of the base 19. An interface pipe 2 is provided at the root of the nozzle 1, and the interface pipe 2 is connected to the front end of the conical pipe 15-1 through a conveying pipe 3. It also includes a blower 8 and a blower motor 7. The air outlet of the blower 8 is connected to the rear end of the nozzle 1. Its operating principle is as follows: the blower 8 sends airflow into the nozzle 1, and the airflow is ejected forward from the nozzle 1, thus creating a negative pressure environment in the conveying pipe 3. Under the action of negative pressure, the seed slurry in the conical pipe 15-1 enters the nozzle 1 through the conveying pipe 3 and is ejected at high speed and at an angle along with the airflow, realizing the hydroseeding construction.

[0030] In this embodiment, a front bracket 5 is installed at the front of the base 19, and a support base 4 with flanges at both the top and bottom is installed on the front bracket 5. A flange is provided at the rear end of the nozzle 1 and is connected to the top flange of the support base 4. A flange is provided at the air outlet of the blower 8 and is connected to the bottom flange of the support base 4.

[0031] A water tank 18 and a water pump 6 are installed on the base 19. The water pump 6 is supported by a pump bracket 21. The top of the water tank 18 has a water inlet. An inlet pipe 15-3 is installed at the bottom of the conical tube 15-1. The inlet of the water pump 6 is connected to the water tank 18, and the outlet of the water pump 6 is connected to the inlet pipe 15-3 through a pipeline. The function of this structure is to periodically start the water pump 6 to send water from the water tank 18 into the space below the partition 15-2 in the conical tube 15-1. Under negative pressure, the water source reaches the nozzle 1 through the delivery pipe 3 and is sprayed out at high speed at an angle along with the airflow. This periodically flushes the movement path of the seed slurry and avoids path blockage.

[0032] It also includes a field controller, which is used to control the start and stop of the mixing assembly 10, the discharge motor 16, the blower 8, and the water pump 6.

[0033] Work style:

[0034] Pre-prepared seed slurry is injected into seed slurry tank 11, and stirring component 10 is started to continuously stir to maintain the uniformity of seed slurry in the tank. The soil spraying greening device is moved by manpower or small machinery. When it arrives at the spraying construction site, blower 8 and slurry discharge motor 16 are started. Seed slurry is discharged into the space above the partition plate 15-2 in the conical tube 15-1. Blower 8 sends airflow into the nozzle 1 and sprays it out at high speed. Correspondingly, a negative pressure environment is formed in the conveying pipe 3. Seed slurry in conical tube 15-1 is sucked into conveying pipe 3. At the same time, external airflow is sucked into the space below partition plate 15-2 and further enters conveying pipe 3. Thus, seed slurry finally enters nozzle 1 and is sprayed out at high speed at an angle along with airflow, realizing the spraying process.

[0035] After a certain period of spraying, the slurry discharge motor 16 is stopped and the water pump 6 is started. The water in the water tank 18 is sent into the space below the conical pipe 15-1 and the partition 15-2. Under the negative pressure environment and the action of airflow, this part of the water reaches the nozzle 1 through the delivery pipe 3 and is sprayed out at high speed along with the airflow, which realizes the cleaning of the seed slurry movement path and effectively avoids the problem of path blockage. After cleaning for a certain period of time, the water pump 6 is stopped and the slurry discharge motor 16 is turned on again to continue spraying.
