[0017] 1. This invention includes a mixing mechanism, a molding mechanism, and a feeding mechanism. The mixing mechanism includes a mixing tank for mixing grass seeds and substrate. The molding mechanism includes a support frame, on which are mounted a conveying mechanism for conveying the grass seed and substrate mixture and an extrusion mechanism for compressing the grass seed and substrate mixture. The output end of the conveying mechanism is connected to the extrusion mechanism. The feeding mechanism includes a feeding conveyor belt and a support frame for supporting the feeding conveyor belt. During operation, the support frame is first rotated so that its plane is parallel to the plane of the slope.

The mixture is then conveyed to the conveying mechanism, which in turn conveys it to the extrusion mechanism, which compresses the mixture into blocks. The compressed mixture falls onto the feeding conveyor belt. As the trolley moves forward, the feeding conveyor belt transports the mixture onto the slope. It enables automatic planting of grass seeds, while extruding the seeds into blocks. The slurry contains water-retaining materials, binding materials, and various nutrients. It provides the water and other nutrients needed for plant growth while effectively preventing rainwater from eroding the spraying material. As a result, the plants can grow healthily and rapidly, ensuring the vegetation coverage rate.

[0018] 2. In this invention, the lower end of the support is hinged to the side of the trolley. A first connecting rod is provided at the lower end of the support, and a first hydraulic cylinder is provided at the lower end of the trolley. The cylinder body of the first hydraulic cylinder is hinged to the trolley, and the piston rod of the first hydraulic cylinder is rotatably connected to the first connecting rod. By extending and retracting the piston rod of the first hydraulic cylinder, the support is driven to rotate, thereby adjusting the tilt angle of the support according to the slope's inclination angle, adapting to slopes with different inclination angles.

[0019] 3. The first driving mechanism in this invention includes a driving wheel, which is rotatably connected to a support. The driving wheel shaft is rotatably connected to the support. A sleeve with a guide push rod is provided inside the support. The left side of the driving wheel is an inclined surface, and the right end of the push rod cooperates with the inner inclined surface of the driving wheel. The sleeve is connected to the extrusion plate by a tension spring. A sprocket is provided at one end of the outer side of the driving wheel shaft, and the driving wheel is driven to rotate by the sprocket chain. During operation, the auger adds the mixture to the extrusion groove. The sprocket is driven to rotate by the motor, and the driving wheel rotates accordingly. The driving wheel cooperates with the push rod, which pushes the push rod to move inward against the elastic force of the tension spring, extruding the mixture in the extrusion groove into a solid block. Then the driving wheel continues to rotate, and under the action of the tension spring, the push rod moves outward, and the mixture block falls. Then the conveying mechanism continues to add the mixture to the extrusion groove, and the driving wheel continues to rotate to extrude the next mixture block. The extrusion efficiency is high.

[0020] 4. In this invention, the right end of the push rod is provided with a ball bearing, which cooperates with the inner inclined surface of the drive wheel. The ball bearing can reduce the friction between the push rod and the drive wheel.

The cylinder body end of the first cylinder is hinged to the second connecting plate, and the piston rod end of the first cylinder is hinged to the first connecting plate. After the mixture is extruded, the piston rod of the first cylinder retracts, the flap flips downward, and the lower end of the extrusion groove opens to facilitate the falling of the mixture block.

[0023] 7. The feeding mechanism of the present invention includes a second cylinder and a pressure plate. The cylinder body end of the second cylinder is mounted on the bracket, and the piston rod end of the second cylinder is connected to the pressure plate. The pressure plate is located in the extrusion groove. After the flip plate flips down and opens, the piston rod of the second cylinder extends out and drives the pressure plate to press down, pressing out the mixed material block in the extrusion groove.

[0024] 8. In this invention, the lower end of the support frame is provided with a support leg, the lower end of the support leg is hinged to the support frame, the front end of the support frame is provided with a second connecting rod, and a second hydraulic cylinder is provided between the front end of the support frame and the front end of the support frame.

The mixture is then conveyed to a conveying mechanism, which in turn conveys it to an extrusion mechanism. The extrusion mechanism compresses the mixture into blocks, which then fall onto a discharge conveyor belt 4. As the trolley moves forward, the discharge conveyor belt 4 transports the mixture onto the slope. This process achieves automated grass seed planting while simultaneously compressing the seeds into blocks. The slurry contains water-retaining materials, binders, and various nutrients, providing the plants with the necessary water and other nutrients while effectively preventing rainwater erosion of the sprayed material. Therefore, the plants can grow healthily and rapidly, ensuring high vegetation coverage.

The lower end of the mixing tank 2 is provided with an opening. When the opening is opened, the mixture falls into the conveying trough and then moves to the right. The mixture is manually conveyed to the feeding trough 9 and then conveyed upward by the feeding auger 10.
