Description
Technical Field
[0001] This utility model relates to slope engineering equipment, specifically to a slope grass seeding device, belonging to the field of slope restoration engineering technology. Background Technology
[0002] With increasing emphasis on the ecological environment, slope ecological restoration has become an important field. Due to their unique topography and soil conditions, slope vegetation restoration is relatively difficult. Traditional sowing and fertilization methods have limited effectiveness in slope environments. To better achieve rapid vegetation restoration and ecosystem reconstruction on slopes, a device capable of simultaneously and efficiently sowing and providing nutrients is needed. This device can apply suitable nutrient substrates during sowing, tailored to the specific soil properties of slopes (such as poor soil or high erosion rates), thereby improving the survival rate and growth rate of grass seeds and accelerating the process of slope ecological restoration.
[0003] Existing slope protection technologies mostly employ hydroseeding, utilizing spraying units equipped with air compressors to directly spray a viscous slurry made from a mixture of grass seeds, adhesives, fertilizers, moisture-retaining agents, green nutrients, and a suitable amount of loose organic matter and water onto steep slopes. This allows for large-scale grass planting in a short time, ensuring close integration of seeds and fertilizers with the soil, resulting in high germination rates and rapid turf establishment, making it particularly suitable for slopes with steep inclines and poor soil conditions. However, in hydroseeding or topsoil planting techniques, the grass seeds and substrate materials used may be lost due to rainwater erosion and wind erosion. Furthermore, hydroseeding technology has limitations, making it difficult to precisely supply nutrients based on the actual soil nutrient status and the grass seed growth stage. It also suffers from high costs and requires sophisticated mixing ratios and spraying techniques. Utility Model Content
[0004] To address the issue that existing slope grass seed and nutrient substrate mixed hydroseeding technology suffers from seed and substrate material loss due to rainwater erosion and wind erosion, this invention provides a slope grass seed application device that integrates functions such as soil breaking, continuous seed and fertilizer spreading, and soil covering. This device can simultaneously fix the grass seeds and nutrient substrate in situ after spreading them on the slope, effectively preventing loss due to rainwater erosion and wind erosion. It boasts advantages such as high sowing efficiency and good sowing effect.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] A slope grass seeding device includes a housing, a drive shaft, wheels, and a seeding mechanism. The drive shaft runs axially through the housing and has wheels at both ends. A vertical partition within the housing divides its interior into separate seed and nutrient chambers. Feed inlets are located at the top of both the seed and nutrient chambers, and discharge outlets are located at the bottom of both chambers.
[0007] The sowing mechanism includes a column, a tiller, and a soil covering. The column has a vertically extending sowing channel, the upper end of which connects to the outlets of both the seed chamber and the nutrient chamber. The tiller is mounted on the front side wall of the column's base. The soil covering has a U-shaped structure with a gradually decreasing diameter from front to back, its front end connecting to the rear side wall of the column's base, and the width of the front opening of the soil covering is greater than the width of the column's base.
[0008] Preferably, the tillage blade has a tapered structure that is wider at the rear than at the front, with the rear end of the blade being wider than the bottom of the column. The bottom end of the blade also extends downward to form a lower tapered section that is wider at the top and narrower at the bottom. The bottom outlet of the seeding channel is located on the rear side wall of the bottom of the column.
[0009] Preferably, a seeding disc is also provided on the drive shaft located inside the seed chamber. Multiple radial seed-blocking plates are evenly arranged along the circumference on the radial sidewall of the seeding disc. The feed port of the seed chamber is located directly above the seeding disc, and the discharge port of the seed chamber is located directly below the seeding disc.
[0010] Preferably, the lower cavity of the seed chamber is an arc-shaped structure that fits the seeding disc and the radial baffle plate. That is, as the seeding disc rotates with the drive shaft, the radial outer end of the radial baffle plate is always in contact with the lower cavity wall of the seed chamber. The axial sidewall of the seeding disc is in contact with the inner wall of the seed chamber.
[0011] Preferably, the radial thickness of the seed chamber is 10-50 cm. The maximum distance between any two adjacent radial baffles is not less than the maximum diameter of the seed chamber's feed inlet or discharge outlet.
[0012] Preferably, a separation disc is also provided on the drive shaft located in the nutrient chamber. Multiple radial baffles are evenly arranged along the circumference of the radial sidewall of the separation disc. The feed port of the nutrient chamber is located directly above the separation disc, and the discharge port of the nutrient chamber is located directly below the separation disc.
[0013] Preferably, the lower cavity of the nutrient chamber is an arc-shaped structure that fits the mass separation disk and the radial baffle plate. That is, as the mass separation disk rotates with the drive shaft, the radial outer end of the radial baffle plate is always in contact with the lower cavity wall of the nutrient chamber. The axial sidewall of the mass separation disk is in contact with the inner wall of the nutrient chamber.
[0014] Preferably, the radial thickness of the nutrient chamber is 10~50cm. The maximum distance between any two adjacent radial baffles is not less than the maximum diameter of the nutrient chamber's feed port or discharge port.
[0015] Preferably, the diameter of the separating disc is the same as that of the seeding disc, and the number and distribution of the radial baffles are the same as those of the radial seeding baffles. A rubber sealing layer is applied to the inner wall of the nutrient chamber, the axial sidewalls of the separating disc, and the radial outer ends of the radial baffles.
[0016] Preferably, multiple parallel housings are connected in series along the axial direction of the drive shaft. The axial distance between two adjacent housings is 5~40cm.
[0017] As a preferred option, a seed storage box is also provided at the inlet of the seed chamber. A nutrient storage box is also provided at the inlet of the nutrient chamber.
[0018] Preferably, an assembly joint is provided on the top of the box (preferably, in order to protect the box, a connecting cover plate for connecting the two is provided between the box and the assembly joint, and the connecting cover plate can be connected to multiple parallel boxes at the same time, so that when there are multiple boxes, only one assembly joint can be provided).
[0019] In this utility model, the term "front" in the directional descriptions such as "front end" and "front side" refers to the direction in which the entire device moves under the action of the walking wheels, and the opposite is "rear". The descriptions of "front" and "rear" are only for the convenience of describing the structure of this utility model, and are not intended to limit this utility model.
[0020] In this invention, the box is mounted on a pair of wheels via a drive shaft. The drive shaft rotates with the wheels, but the box does not rotate with the drive shaft. That is, the drive shaft only supports the box (for example, the drive shaft and the box are connected by a bearing). The movement of the wheels on the slope drives the box to move, thereby quickly spreading grass seeds and nutrient substrate. Meanwhile, to prevent the sown grass seeds and nutrient substrate from being exposed on the slope surface and easily washed away by rainwater or wind erosion, this utility model has a specially structured sowing mechanism at the discharge port at the bottom of the box. It mainly includes a column, a tiller, and a soil cover. The tiller is set at the bottom of the column and is used to break the soil as the box moves forward and push the soil to both sides to form a trench to contain the grass seeds and nutrient substrate. It should be noted that the width of the rear end of the tiller is greater than the width of the column, so that the width of the trench is greater than the width of the column. At the same time, the lower end of the tiller extends downward beyond the bottom of the column, so that the depth of the trench is below the bottom of the column. In other words, the trench of a certain width and depth is plowed by the specially structured tiller so that the bottom outlet of the column is completely placed in the trench, so as to accurately and quickly sow the grass seeds and nutrient substrate into the trench. The soil covering is located at the rear of the bottom of the column, and has a U-shaped structure that is wider at the front and narrower at the back. After the grass seeds and nutrient substrate are sown, it gathers the soil that was previously pushed to the sides and covers the grass seeds and nutrient substrate, thus burying and fixing them, effectively preventing their flow. In other words, this invention can achieve deep sowing and real-time burial of grass seeds and nutrient substrate, with high sowing efficiency and good sowing effect.
[0021] Furthermore, multiple parallel boxes are connected in series along the axial direction of the drive shaft. Each box has an independent sowing mechanism at its bottom, enabling simultaneous sowing of grass seeds and nutrient substrate within a certain width area of the slope, significantly improving application efficiency. Even further, a prefabricated joint is provided on the top of the box, allowing external hoisting machinery (such as an excavator) to be connected. This enables the device to operate stably on slopes of varying gradients (especially steep slopes), significantly saving manpower, reducing labor costs, and improving application efficiency. It should be noted that when multiple parallel boxes are present, a connecting cover is provided on the top of all boxes, and the prefabricated joint is then mounted on the connecting cover.
[0022] In this invention, a seed-distributing disc, rotatable with the drive shaft, is mounted on the drive shaft inside the seed chamber. Multiple radial seed-blocking plates are evenly arranged circumferentially on the radial sidewall (i.e., its circumferential sidewall) of the seed-distributing disc. A U-shaped seed-distributing groove is formed between any two radial seed-blocking plates and the radial sidewall of the seed-distributing disc. In other words, the seed-distributing disc has multiple consecutive adjacent U-shaped seed-distributing grooves in its circumferential direction. This arrangement of multiple U-shaped seed-distributing grooves ensures that seeds added from the seed chamber's feeding port are evenly dispersed within each U-shaped seed-distributing groove. As the seed-distributing disc rotates, the seeds from each U-shaped seed-distributing groove are discharged from the seed chamber's discharge port at certain time intervals. In other words, the design of the seed-distributing disc and multiple radial seed-blocking plates achieves both even seed discharge from the seed box, preventing over-sowing or missed sowing, and allows for batch and timed sowing of the seeds, ensuring sufficient spacing between the seeds sown at different times to provide ample space for later growth.
[0023] Furthermore, to prevent seeds from scattering during rotation within the various U-shaped seeding troughs, the lower cavity of the seed chamber is an arc-shaped structure (preferably a semi-circular structure) that fits the seeding disc and the radial seed-blocking plate. This means that as the seeding disc rotates with the drive shaft, the outer radial end of the radial seed-blocking plate remains in contact with the lower cavity wall of the seed chamber. The axial sidewall of the seeding disc is in contact with the inner wall of the seed chamber. In other words, each U-shaped seeding trough is an independent area, effectively preventing seeds from mixing and falling between different U-shaped seeding troughs, thus avoiding uneven sowing.
[0024] In this invention, to facilitate the uniform discharge of seeds from the seed box, a seed-separating disc and multiple radial baffles (with the same structure as the seed-separating disc and its radial baffles) are also installed on the drive shaft inside the nutrient chamber, forming multiple independent U-shaped seed-separating troughs (the number and position of the U-shaped seed-separating troughs correspond one-to-one). The seed-separating disc and the seed-separating disc rotate with the same drive shaft, thereby simultaneously sowing a certain number of seeds and a certain amount of nutrient substrate. Through the synchronous sowing of seeds and nutrient substrate in different zones, the uniformity and stability of the seed-nutrient substrate ratio are significantly improved, realizing quantitative and fixed-point sowing of seeds and nutrient substrate, thus providing stable and balanced nutritional support for the growth of grass seeds.
[0025] Furthermore, the lower cavity of the nutrient chamber is also an arc-shaped structure (preferably a semi-circular structure) that fits the separating disc and the radial baffle plate, thereby preventing cross-flow between nutrient substrates. Furthermore, the inner wall of the nutrient chamber, the axial sidewall of the separating disc, and the radial outer end of the radial baffle plate are all covered with a rubber sealing layer. This rubber sealing layer further prevents cross-flow of nutrient substrates (especially highly fluid nutrients such as nutrient solutions or nutrient slurries), further ensuring the stability of the seed-to-nutrient substrate sowing ratio.
[0026] In this invention, in order to improve the uniformity of mixing between seeds and nutrient substrate, multiple downward-sloping and relatively staggered guide plates are provided in the sowing channel that runs through the column from top to bottom. During the flow of seeds and nutrient substrate from top to bottom, uniform mixing is achieved through the interactive guidance of multiple guide plates; or, the sowing channel is a spiral channel from top to bottom.
[0027] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0028] 1. The slope grass seeding device of this utility model integrates a walking seed and nutrient substrate box with soil breaking, seed and fertilizer mixing and sowing, and soil filling into one unit, which can realize the efficient sowing and fixation of slope seeds and nutrient substrate, and avoid the loss caused by rainwater erosion, wind erosion and other reasons.
[0029] 2. The slope grass seeding device of this utility model has a simple overall structure, high seed and fertilizer application efficiency, stable seed and fertilizer ratio application, low labor cost, and is easy to operate. In addition, it also has the advantages of strong slope adaptability, low preparation cost, and strong practicality. Attached Figure Description

[0065] The slope grass seeding device of this utility model is used as follows: The prefabricated connector 5 is connected to the excavator's mechanical arm. The excavator hoists the device onto the slope and rolls it down the slope at a certain speed. A certain amount of grass seeds and nutrient substrate are pre-filled in the seed storage box 108 and the substrate storage box 109. The top of the seed chamber 102 and the top of the nutrient chamber 103 are opened, and the opening of the feeding ports is controlled to ensure that the amount of grass seeds and the mass of nutrient substrate flowing down per unit time are in an optimal ratio. As the device descends along the slope, the seed distribution disc 104 and the substrate distribution disc 106 rotate synchronously with the drive shaft 2. The U-shaped seed distribution area formed between the radial seed baffles 105 and the U-shaped substrate distribution area formed between the radial substrate baffles 107 simultaneously feed a certain amount of grass seeds and nutrient substrate into the seeding mechanism 4 at a certain frequency during rotation, using the same angular velocity. In the process, the material is discharged into the soil from the outlet located at the bottom rear of the column 401. At the same time, under the action of external force and its own gravity, the tiller 402 and the lower cone 404 are inserted into the soil and plow a trench for placing seeds and nutrient substrate as the device moves forward. After the seeds and nutrient substrate are placed, the soil that was previously plowed to both sides of the trench is gathered and covered on the trench where the seeds and nutrient substrate have been placed under the forward-moving and gathering action of the covering cover 403. This achieves the burial and positioning of the seeds and nutrient substrate, preventing them from being washed away by rain or blown away by wind. By repeating the above process, the sowing of seeds and nutrient substrate on the slope can be continuously achieved.
