Description

Technical Field

[0001] This application relates to the field of hydroseeding materials, specifically to a processing technology for hydroseeding materials. Background Technology

[0002] Traditional hydroseeding materials are typically prepared on hydroseeding machines. However, due to variations in equipment configuration between machines, the quality of the hydroseeding materials produced varies, leading to inconsistent quality and inconsistent results. This results in vastly different greening effects in different areas of the same project. Traditional hydroseeding machines are usually vehicle-mounted, and due to limited space, the screening machines are often simple grid screens with poor screening efficiency, allowing gravel to enter the machine and clog the nozzles. Furthermore, limited space restricts the selection of mixing equipment for traditional hydroseeding machines. Insufficient power, undersized mixing tanks, or ineffective control of the added hydroseeding material ratio often result in incomplete mixing and low seed germination rates. Summary of the Invention

[0003] The technical problem to be solved by this invention is to overcome the shortcomings and defects mentioned in the background art above, and to provide a standardized processing technology for topsoil spraying materials that ensures stable product quality, reduces nozzle clogging, and improves grass seed germination rate. To solve the above technical problem, the technical solution proposed by this invention is as follows: A process for processing topsoil spraying material includes: transporting topsoil to a topsoil silo, feeding the topsoil to a first conveyor via a first feeder, conveying the topsoil to a vibrating screen via the first conveyor, screening the topsoil by the vibrating screen, transporting the crushed stone on the screen to a crushed stone storage yard via a second conveyor, and transporting the undersize material to a topsoil storage yard via a third conveyor. The screened material is fed to the No. 4 conveyor via the No. 2 feeder. The No. 4 conveyor transports the screened material to the mixing tank. Grass seeds, water, fertilizer and additives are added to the mixing tank and then mixed. The mixed topsoil spraying material is then sprayed by the spraying machine.

[0004] In one embodiment, the No. 1 conveyor, No. 2 conveyor, No. 3 conveyor and No. 4 conveyor are belt conveyors.

[0005] In one embodiment, the No. 1 feeder and the No. 2 feeder are vibrating feeders.

[0006] In one embodiment, the vibrating screen is a linear vibrating screen or a circular vibrating screen.

[0007] In one embodiment, the linear vibrating screen or the circular vibrating screen is a single-layer screen, and the screen aperture size of the single-layer screen is no greater than 25mm.

[0008] In one embodiment, the crushed stone in the crushed stone storage yard is used for paving or mixing concrete.

[0009] In one embodiment, the mixing tank is equipped with a twin-shaft mixer.

[0010] Compared with existing technologies, the beneficial effects of this invention are as follows: The process of this application sets up a hydroseeding material processing area, which standardizes the preparation of hydroseeding materials, thereby ensuring stable hydroseeding results. Various raw materials (topsoil, grass seeds, fertilizer, etc.) are centrally transported to the hydroseeding material processing area for processing, replacing the traditional scattered operation at multiple, dispersed slope sites. This centralized management and resource utilization of materials enables large-scale production. By establishing a fixed production center, integrating processing procedures, and adopting automated production line equipment, it successfully upgrades topsoil hydroseeding from a "dispersed, extensive, and manual" field operation to a "centralized, refined, and mechanized" large-scale, industrialized production model. Stable feeding is achieved through the feeder and conveyor, ensuring the proportion of each material in the mixing tank and guaranteeing the stability of the final hydroseeding material quality. The vibrating screen removes large pieces of gravel and impurities, resulting in fine, uniformly sized soil. This avoids the risk of gravel clogging the sprayer nozzles, reducing equipment failure rates and maintenance costs, ensuring continuous construction, and guaranteeing more uniform mixing with subsequent additives such as grass seeds and fertilizers, preventing sprayer blockage. The gravel remaining on the screen is transported to a gravel storage area and can be used in other projects such as paving or concrete mixing, achieving classified management and comprehensive utilization of resources and reducing waste disposal costs. Thorough mixing in the mixing tank improves the mixing effect of grass seeds with topsoil, fertilizers, and additives, ultimately increasing the germination rate of the grass seeds.

[0014] To facilitate understanding of the present invention, the present invention will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of protection of the present invention is not limited to the following specific embodiments.

[0015] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of the invention.

[0016] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0017] Please see Figure 1 The processing technology of the topsoil spraying material according to one embodiment mainly includes: transporting topsoil to topsoil silo 2, feeding the topsoil to conveyor 4 via feeder 3, conveyor 4 conveying the topsoil to vibrating screen 5, screening the crushed stone on the vibrating screen 5, transporting the crushed stone on the screen to crushed stone storage yard 7 via conveyor 6, and transporting the undersized material to topsoil storage yard 9 via conveyor 8; feeding the undersized material to conveyor 11 via feeder 10, conveyor 11 conveying the undersized material to mixing tank 12, adding grass seeds, water, fertilizer and additives to mixing tank 12, and then spraying the mixed topsoil spraying material through a spraying machine.

[0018] More specifically, topsoil is transported to topsoil silo 2 by dump truck 1, and topsoil silo 2 is equipped with feeder 3.

[0019] Preferably, the No. 1 feeder 3 and the No. 2 feeder 10 are vibrating feeders, both of which have vibration function. The appropriate specification of the vibrating feeder is selected to meet the feeding requirements based on the material throughput of this process section, and the feeding amount can be adjusted according to the process requirements.

[0020] Preferably, conveyors 4 (number 1), 6 (number 2), 8 (number 3), and 11 (number 4) are belt conveyors. Belt conveyors can form a continuous material flow, thus having a very large conveying capacity. The design of the belt width, belt speed, and trough angle can meet the conveying requirements from several tons to tens of thousands of tons per hour, making them very suitable for scenarios such as topsoil spraying material production lines that require continuous and large-scale material processing. They can promptly transport large quantities of topsoil and gravel to the next process, ensuring uninterrupted production flow. They can easily connect spatially dispersed topsoil silos 2, gravel storage yards 7, topsoil storage yards 9, and mixing tanks 12, achieving cross-regional process integration.

[0021] Preferably, the vibrating screen 5 can be a linear vibrating screen or a circular vibrating screen, with a single-layer screen. The screen material is not specified, but to prevent stones from clogging the spraying machine nozzles, the screen aperture size must not exceed 25mm. In one embodiment, the linear or circular vibrating screen is a single-layer screen, and the screen aperture size of the single-layer screen is not greater than 25mm. By using a single-layer screen and controlling the screen aperture, the risk of spraying machine clogging can be eliminated, ensuring continuous and uninterrupted construction, and ensuring that a uniform, efficient, and highly adhesive high-quality topsoil spraying material can be obtained. The single-layer screen and flexible selection reduce purchase and maintenance costs. S40, the mud powder is transported to the mixing tank 16 by conveyor No. 3 15, and the mud cake is transported to the mixing tank 16 by conveyor No. 4 10. Crushed stone storage yard 7 is used to store crushed stone from the screen. The crushed stone from the screen can be transported by dump truck to various construction sites for paving, concrete mixing, etc., to achieve comprehensive utilization of resources.

[0022] The topsoil storage area 9 is used to store the topsoil that is screened out. The topsoil that is screened out is used as raw material for hydroseeding. The topsoil storage area 9 is enclosed to prevent rainwater from washing away the topsoil.

[0023] The mixing tank 12 is used to mix the spraying material. The topsoil is transported to the mixing tank 12 by the No. 4 conveyor 11. Grass seeds, water, fertilizer and additives are added to the mixing tank 12 in proportion. The mixed spraying material is transported to each spraying machine by the mud pump 13, and the machine then performs the spraying operation.

[0024] Preferably, the mixing tank 12 is equipped with a twin-shaft mixer. Using a twin-shaft mixer ensures that the screened material, grass seeds, water, fertilizer, and additives are distributed extremely evenly in the viscous topsoil. Even if the material is viscous or contains a small amount of unscreened grass roots or fiber bundles, the twin-shaft mixer can effectively break it up and mix it evenly, preventing "shaft sticking" (material adhering to the shaft) or jamming, thus ensuring continuous production. It directly avoids the patchy baldness phenomenon of "some areas with dense grass and some areas with sparse grass" after hydroseeding, ensuring the uniformity of the greening effect and the success rate.

[0025] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
