[0048] Reference Figures 1 to 2 As shown, the present invention provides a high-steep slope soil-planting grass spraying device based on feeding assistance, including a spraying trolley and a box body 2, which is installed on the spraying trolley. A feed hopper 16 is provided at the top of the box body 2, and a crushing mechanism, a grinding and refining mechanism, a screening assembly, a blowing mechanism and a mixing mechanism are sequentially arranged in the box body 2 from top to bottom. A discharge pipe 21 is provided at the bottom of the box body 2, and the discharge pipe 21 is connected to the spray gun on the spraying trolley; the grinding and refining mechanism includes a fixed ring 11 fixedly sleeved on the inner wall of the box body 2, and a rolling table 12 is slidably fitted in the fixed ring 11, and the rolling table 12 is driven by a motor 1.

[0049] In this embodiment, a mixing hopper 5 is provided on the outer wall of the box body 2 near the mixing mechanism for adding a seed water-retaining agent and an adhesive to mix with the ground and refined guest soil.

[0050] During use, the guest soil enters the box body 2 through the feed hopper 16, is crushed in turn by the crushing mechanism, the crushed guest soil is ground and refined by the grinding and refining mechanism, and then is sieved by the screening mechanism. The guest soil that meets the particle diameter enters the mixing mechanism and is fully mixed with the seed water-retaining agent and adhesive added through the batching hopper 5, and finally enters the spray gun on the spraying vehicle through the discharge pipe 21 and is sprayed to the planting area.

[0051] Furthermore, the crushing mechanism includes two crushing rollers 17 rotatably connected to opposite side walls of the box body 2. The two crushing rollers 17 are arranged in parallel. The same-side rotating shafts of the two crushing rollers 17 pass through the side wall of the box body 2 and are connected to a gear 14. The two gears 14 are meshed with each other. The output end of the reduction motor 15 is connected to the rotating shaft of one crushing roller 17, and the reduction motor 15 is installed on the outer wall of the box body 2.

[0052] The reduction motor 15 drives the rotating shaft on a crushing roller 17 to rotate, and the two crushing rollers 17 rotate towards each other through the meshing transmission of two gears, thereby crushing the large pieces of foreign soil.

[0053] Furthermore, motor 1 is installed in the middle of the bottom end of the box body 2, and the output shaft of motor 1 passes through the bottom wall of the box body 2 and is vertically connected to the rotating rod 23. The rotating rod 23 is coaxially arranged with the box body 2, and the rolling table 12 is coaxially connected to the rotating rod 23. The rolling table 12 is in friction contact with the inner ring of the fixed ring 11, and the contact surface between the rolling table 12 and the fixed ring 11 is provided with multiple vertical grooves 10 at equal intervals along the circumference of the rotating rod 23.

[0054] The crushed imported soil falls to the junction of the rolling table 12 and the fixed ring 11, among which the smaller imported soil particles slide onto the screening mechanism through the vertical groove 10, and the larger imported soil particles are refined by the rolling table 12 and the fixed ring 11. Specifically, the motor 1 drives the rotating rod 23 and the rolling table 12 to rotate, and the grinding is achieved through the friction between the rolling table 12 and the inner ring of the fixed ring 11.

[0055] Furthermore, in order to facilitate the passage of fine soil particles, the cross section of the vertical groove 10 is semicircular.

[0056] Furthermore, the upper part of the rolling table 12 is a conical structure, and the rolling table 12 is a hollow structure. An opening is provided on the top of the rolling table 12, and the opening is fixedly connected to the rotating rod 23 through a connecting rod. A conical cap 13 is provided above the opening, and the conical cap 13 is used to cover the opening. The inner wall of the rolling table 12 is inclinedly provided with multiple arc-shaped guide plates 9, and the arc-shaped guide plates 9 are used to guide the foreign soil intercepted on the screening assembly to the opening. The top of the arc-shaped guide plate 9 is flush with the opening, and the bottom end of the arc-shaped guide plate 9 is in friction contact with the screening assembly.

[0057] The upper part of the grinding table 12 is set to a conical structure, which is conducive to guiding the crushed foreign soil and ensuring that it slides smoothly to the junction of the grinding table 12 and the fixed ring 11. The conical cap 13 is provided to prevent the crushed foreign soil from falling into the opening and not being effectively ground. While grinding, the arc-shaped guide plate 9 contacts the upper surface of the screening component and shovels the larger particles of foreign soil intercepted on the upper surface of the screening component. Under its guiding action, the shoveled larger particles of foreign soil slide through the opening to the junction of the grinding table 12 and the fixed ring 11 for secondary grinding, thereby ensuring the fineness of the foreign soil.

[0058] Furthermore, the screening assembly includes a filter plate 18 fixedly connected to the inner wall of the box body 2. The filter plate 18 is provided with a plurality of filter holes. The plurality of filter plates 18 are arranged in a circular array.

[0059] The imported soil particles that meet the particle size requirements pass through the filter holes smoothly for the next step of mixing, and the imported soil particles that do not meet the particle size requirements are intercepted on the upper surface of the filter plate 18 and are shoveled by the arc guide plate 9 for secondary grinding.

[0060] Furthermore, the blowing mechanism includes a connecting rod 20 fixedly connected horizontally to the rotating rod 23, and the end of the connecting rod 20 away from the rotating rod 23 is connected to the air injection pipe 19, and a plurality of air injection holes are opened on the air injection pipe 19, and anti-blocking parts are provided on the air injection holes, and the air injection holes are facing the screening assembly. The air injection pipe 19 is connected to the air supply device through a hose.

[0061] The anti-blocking member is provided to prevent foreign soil from falling into the air jet hole and causing blockage. In this embodiment, the air supply device is a small air pump, which blows air to the filter plate 18 to blow out the foreign soil particles blocking the filter hole, thereby ensuring the effectiveness of the screening assembly.

[0062] Furthermore, the anti-blocking member includes a plurality of fan-shaped baffles 22 connected to the circumference of the air jet hole. The plurality of fan-shaped baffles 22 are enclosed to form a circular piece. The fan-shaped baffles 22 are soft silicone films.

[0063] After ventilation, the internal pressure of the air injection pipe 19 rises and blows open the plurality of fan-shaped baffles 22. When the air blowing stops, the fan-shaped baffles 22 return to their original position under the elastic action of themselves, thereby effectively protecting the air injection holes.

[0064] Furthermore, the mixing mechanism includes a sliding rod 8 connected at equal intervals along the circumference of the outer wall of the rotating rod 23, and a sliding sleeve on the sliding rod 8 is provided with multiple springs 7 and multiple stirring blades 6, and the stirring blades 6 and the springs 7 are alternately arranged. The coaxial fixed sleeve on the rotating rod 23 is provided with a distribution wheel, and the distribution wheel is located below the stirring blade 6.

[0065] The reciprocating vibration characteristics of the spring 7 and the rotary shearing of the stirring blade 6 form a resonance effect. When the motor 1 stops, the residual material automatically falls off under the action of the spring residual vibration.

[0066] The sliding rods 8 arranged circumferentially with intervals form a centrifugal stirring field when rotating, and cooperate with the rotation disturbance of the coaxial distribution wheel at the bottom to build a "upward rotation and downward distribution" double circulation flow field in the mixing chamber.

[0067] Furthermore, the distribution wheel includes a turntable 3 coaxially fixedly sleeved on the rotating rod 23 , and a plurality of arc-shaped blocking pieces 4 are provided at equal intervals on the top end of the turntable 3 along the circumference of the rotating rod 23 .

[0068] The bottom material is thrown upward by the arc-shaped baffle 4 on the distribution wheel, forming convection with the stirring area of ​​the slide rod 8, so that the components such as the guest soil, water retaining agent, and grass seeds are evenly mixed, further improving the uniformity of the mixing.

[0069] The feed-assisted high-steep slope imported soil grass planting spraying device provided by the present invention has a working principle as follows: when in use, the imported soil enters the box body 2 through the feed hopper 16, is crushed in turn by the crushing mechanism, the crushed imported soil is ground and refined by the grinding and refining mechanism, and then is screened by the screening mechanism. The imported soil that meets the particle diameter enters the mixing mechanism and is fully mixed with the seed water-retaining agent and adhesive added through the material hopper 5, and finally enters the spray gun on the spraying vehicle through the discharge pipe 21 and is sprayed to the planting area; the imported soil intercepted on the filter plate 18 is shoveled by the arc-shaped guide plate 9 under its guiding action, and the shoveled granular imported soil slides through the opening to the junction of the grinding table 12 and the fixed ring 11 for secondary grinding, thereby ensuring the fineness of the imported soil.
