Abstract
Description
Technical Field
[0001] The utility model relates to the field of grass planting spraying equipment, and more specifically, to a secondary admixture spraying equipment for grass planting spraying. Background Art
[0002] With the development of infrastructure construction such as highways and railways in mountainous areas, many high-fill and deep-excavation road base sections have been generated. Due to the influence of factors such as soil excavation and vegetation destruction, many projects have caused disasters such as soil erosion and slope instability in the surrounding environment after completion, posing a serious threat to the ecological security of the region. Therefore, it is extremely important to reinforce the slopes and carry out ecological restoration on the excavated and damaged slopes.
[0003] Spray seeding is a common slope repair technique that involves mixing grass seeds, adhesives, fertilizers, water, and soil, then spraying them onto the excavated slope using a sprayer. This creates a matrix layer of soil containing plant seeds on the damaged slope. However, the matrix layer formed by mixing grass seeds, adhesives, fertilizers, water, and soil in current sprayers has poor fluidity, leading to pipe blockage during the spraying process, resulting in fluid failure or poor spraying. While increasing the moisture content of the matrix layer improves its fluidity, the excessive fluidity of the matrix sprayed onto the slope causes it to flow down the slope, resulting in a "loose" layer. Utility Model Content
[0004] In order to achieve these purposes and other advantages according to the present invention, a preferred embodiment of the present invention provides a secondary admixture spraying device for grass planting spraying, comprising:
[0005] The mixer comprises a mixing drum, a mixing shaft and a mixing blade. The mixing shaft is arranged in the mixing drum, and the mixing blades are evenly distributed on the mixing shaft.

[0015] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 This is a schematic structural diagram of the secondary admixture spraying equipment for grass planting spraying in the utility model. DETAILED DESCRIPTION
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
[0018] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0019] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.
[0020] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0021] like Figure 1 As shown, a preferred embodiment of the present invention provides a secondary admixture spraying device for grass planting spraying, comprising:
[0022] The mixer comprises a mixing drum 1, a mixing shaft 2 and a mixing blade 3. The mixing shaft 2 is arranged in the mixing drum 1, and the mixing blades 3 are evenly distributed on the mixing shaft 2. The mixing shaft 2 is driven by a motor 10 to rotate. A feeding port 4 and a water injection port 5 are provided at the top of the mixing drum 1, and a slurry extraction port 6 is provided at the bottom of the mixing drum 1.
[0023] A matrix layer delivery pipe 7, one end of which is connected to the slurry extraction port 6 through a pipe, and a stirring head 8 is provided in the pipe opening at the other end to form a slurry spraying port;
[0024] The exciter delivery pipe 9 is vertically connected to the matrix layer delivery pipe 7 .
[0025] In the above technical solution, after the matrix layer containing the main curing agent is transported through the mixer's slurry extraction port into the pipeline, the addition of an activator during transportation rapidly causes the ejected matrix layer to lose fluidity. The stirring head at the pipe nozzle functions to uniformly mix the ejected matrix layer, the main curing agent, and the activator. When the ejected matrix layer contacts the slope, the activating effect of the activator and the hydration of the main curing agent rapidly reduce its fluidity, transforming it from a fluid state to a plastic state, allowing it to cling to the slope. The plant seeds in the matrix layer are evenly dispersed along the slope, thereby reinforcing and repairing excavated and damaged slope surfaces.
[0026] According to a preferred embodiment of the present invention, walking wheels are installed at the bottom of the mixing drum 1 to facilitate walking and moving during construction.
[0027] According to a preferred embodiment of the present invention, the diameter of the activator delivery pipe 9 is smaller than the diameter of the matrix layer delivery pipe 7. This is because the amount of activator added is much smaller than that of the matrix layer, so the corresponding pipe diameter is set smaller.
[0028] According to a preferred embodiment of the present invention, the activator delivery pipe 9 avoids both ends of the matrix layer delivery pipe 7. This ensures that the activator can have more contact with the matrix layer before the matrix layer and the activator reach the spraying port, which can also improve mixing to a certain extent. Specifically, the activator delivery pipe 9 is connected to the middle part of the matrix layer delivery pipe 7.
[0029] According to a preferred embodiment of the present invention, the stirring head 8 is connected to a power mechanism, and the power mechanism is used to drive the stirring head to rotate.
[0030] According to a preferred embodiment of the present invention, the size of the slurry extraction port 6 is consistent with the size of the matrix layer conveying pipeline, so that the stirred matrix layer can directly enter the matrix layer conveying pipeline from the slurry extraction port.
[0031] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described here.
