Abstract
Description
Technical Field
[0001] This utility model relates to the field of ecological and environmental protection equipment technology, and in particular to a grass seed drug mixing device based on ecological restoration. Background Technology
[0002] In existing technologies, the mixing of grass seeds and dust suppressants (or drugs) often relies on traditional mixing equipment, which mostly employs a unidirectional or single-layer mixing structure, resulting in obvious mixing dead zones and insufficient material bonding. This uneven mixing directly affects the germination rate of grass seeds and the effectiveness of dust suppressants.
[0003] Furthermore, the mixing and spreading processes are usually separate, requiring multiple transfers and unloading, resulting in low operational efficiency and high reliance on manual labor, making it difficult to meet the continuous operational needs of large-scale ecological restoration. Dry spreading methods are prone to dust pollution, and if the dust suppressant is not fully mixed with the grass seeds beforehand, it cannot effectively suppress the dust generated during this process. At the same time, traditional equipment lacks an efficient conveying system, making it difficult to achieve uniform spreading on complex terrains such as slopes. Utility Model Content
[0004] In view of the above-mentioned problems in the prior art, this utility model is proposed.
[0005] The purpose of this invention is to provide a grass seed drug mixing device based on ecological restoration, which aims to solve the problems of uneven mixing of grass seeds and dust suppressants (caused by dead corners in unidirectional mixing), low sowing efficiency (requiring multiple transfers between mixing and sowing stages), and dust pollution during sowing (due to the dust suppressant not being mixed synchronously) in the existing technology.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grass seed drug mixing device based on ecological restoration, including a vehicle body,
[0007] The mixing unit includes a mixing tank disposed on the vehicle body, mixing components disposed at the top and bottom of the mixing tank, a feed inlet disposed at the top of the mixing tank, and a discharge outlet disposed at the bottom of the mixing tank.
[0008] The feeding unit includes a hopper disposed on the vehicle body and a feeding assembly disposed between the hopper and the feeding port;
[0009] The spreading unit includes a negative pressure conveying pump mounted on the vehicle body, an inlet pipe and an outlet pipe mounted on the negative pressure conveying pump, and a spraying assembly mounted at one end of the outlet pipe.
[0010] As a preferred embodiment of the grass seed drug mixing device based on ecological restoration of this utility model, the mixing assembly includes a mixing motor disposed at the top and bottom of the mixing tank, a rotating rod disposed at the output end of the mixing motor, and a mixing rod disposed on the outer wall of the rotating rod.

[0012] As a preferred embodiment of the grass seed drug mixing device based on ecological restoration of this utility model, the spraying component includes a connecting pipe disposed on the vehicle body and a nozzle disposed on the connecting pipe.
[0013] As a preferred embodiment of the grass seed drug mixing device based on ecological restoration of this utility model, the two mixing components are mixed in opposite directions.
[0014] As a preferred embodiment of the grass seed drug mixing device based on ecological restoration of this utility model, the feed pipe and the discharge port are connected.
[0015] The beneficial effects of this utility model of grass seed and dust suppressant mixing device based on ecological restoration are as follows: the quantitative and precise feeding of grass seeds and dust suppressant is achieved through the hopper and feeding components; the strong convection shearing is formed by two sets of mixing components with opposite directions at the top and bottom of the mixing tank, which efficiently eliminates mixing dead corners and ensures that the materials are mixed quickly, fully and evenly; the mixed grass seed dust suppressant is continuously extracted by the negative pressure conveying pump through its feed pipe through the discharge port at the bottom of the mixing tank, and is evenly and mechanically spread through the spraying components. This not only greatly improves the mixing uniformity and work efficiency, but also suppresses dust during the spreading process, making it particularly suitable for continuous integrated operation of large-scale ecological restoration projects.

[0025] Example 1
[0026] Reference Figure 1 This is the first embodiment of the present invention, which provides a grass seed drug mixing device based on ecological restoration, including a vehicle body 100.
[0027] The mixing unit 1 includes a mixing tank 11 disposed on the vehicle body 100, a mixing assembly 12 disposed on the top and bottom of the mixing tank 11, a feed inlet 13 disposed on the top of the mixing tank 11, and a discharge outlet 14 disposed on the bottom of the mixing tank 11.
[0028] The feeding unit 2 includes a hopper 21 disposed on the vehicle body 100, and a feeding assembly 22 disposed between the hopper 21 and the feeding port 13;
[0029] The spreading unit 3 includes a negative pressure conveying pump 31 mounted on the vehicle body 100, an inlet pipe 32 and an outlet pipe 33 mounted on the negative pressure conveying pump 31, and a spraying assembly 34 mounted at one end of the outlet pipe 33.
[0030] The two stirring components 12 stir in opposite directions, and the feed pipe 32 is connected to the discharge port 14.
[0031] It should be noted that a mixing tank 11 is fixedly welded onto the vehicle body 100. A mixing assembly 12 is provided at the top and bottom of the mixing tank 11, and the two sets of mixing assemblies 12 rotate in opposite directions to eliminate mixing dead zones to the maximum extent and significantly improve overall uniformity. A feed inlet 13 is provided at the top of the mixing tank 11, and a discharge outlet 14 is provided at the bottom of the mixing tank 11.
[0032] A hopper 21 is fixedly connected to the vehicle body 100 and located diagonally above the mixing tank 11. The hopper 21 and the feed inlet 13 are connected by a feeding assembly 22, which enables quantitative feeding.
[0033] A negative pressure conveying pump 31 is fixedly connected to the vehicle body 100 and located on one side of the mixing tank 11. The feed pipe 32 of the negative pressure conveying pump 31 is connected to the discharge port 14. The discharge pipe 33 of the negative pressure conveying pump 31 is connected to a spraying assembly 34, which sprays the mixed grass seeds evenly.
[0034] In use, grass seeds and liquid dust suppressant are respectively put into hopper 21. The grass seeds are quantitatively conveyed from hopper 21 to the feed inlet 13 at the top of mixing tank 11 according to the set ratio and rate by the feeding component 22. The top and bottom mixing components 12 start at the same time and rotate in opposite directions to form strong convection shear. The counter-rotating double mixing components 12 eliminate mixing dead corners to the maximum extent, ensuring that the grass seeds and dust suppressant are quickly, fully and evenly mixed in the tank. The evenly mixed grass seed-dust suppressant mixture settles to the bottom of mixing tank 11. The negative pressure conveying pump 31 continuously draws the mixed material through its feed pipe 32. The material is pumped into the discharge pipe 33 under negative pressure. The spraying component 34 at the end of the discharge pipe 33 sprays the drawn grass seed-dust suppressant mixture evenly onto the target area.
[0035] In summary, the hopper 21 and feeding components 22 enable precise quantitative feeding of grass seeds and dust suppressants. The two sets of opposing mixing components 12 at the top and bottom of the mixing tank 11 form a powerful convection shear, effectively eliminating mixing dead zones and ensuring rapid, thorough, and uniform mixing of materials. The mixed grass seed dust suppressant is continuously extracted by the negative pressure conveying pump 31 through its feed pipe 32 through the discharge port 14 at the bottom of the mixing tank 11, and uniformly and mechanically spread through the spraying components 34. This not only significantly improves the mixing uniformity and work efficiency, but also suppresses dust during the spreading process, making it particularly suitable for continuous integrated operations in large-scale ecological restoration projects.
[0036] like Figure 3 As shown, in a preferred embodiment, the stirring assembly 12 includes a stirring motor 131 disposed at the top and bottom of the stirring tank 11, a rotating rod 132 disposed at the output end of the stirring motor 131, and a stirring rod 133 disposed on the outer wall of the rotating rod 132.
[0037] It should be noted that a stirring motor 131 is fixedly connected to the top and bottom of the mixing tank 11, a rotating rod 132 is fixedly connected to the output end of the stirring motor 131, and a stirring rod 133 is fixedly connected to the outer wall of the rotating rod 132. The stirring motor 131 drives the rotating rod 132 to rotate, thereby driving the stirring rod 133 to stir.
[0038] like Figure 2 As shown, in a preferred embodiment, the feeding assembly 22 includes a conveying pipe 221 disposed between the hopper 21 and the feed inlet 13, a conveying motor 222 disposed on one side of the conveying pipe 221, a conveying rod 223 disposed at the output end of the conveying motor 222, and a spiral blade 224 disposed on the conveying rod 223.
[0039] It should be noted that the hopper 21 and the feed inlet 13 are connected by a conveying pipe 221. A conveying motor 222 is fixedly connected to one side of the conveying pipe 221. A conveying rod 223 is rotatably connected to the inner cavity of the conveying pipe 221. The conveying rod 223 is fixedly connected to the output end of the conveying motor 222. A spiral blade 224 is fixedly connected to the outer wall of the conveying rod 223. Quantitative feeding is achieved by rotating the spiral blade 224.
[0040] like Figure 4 As shown, in a preferred embodiment, the spraying assembly 34 includes a connecting pipe 341 disposed on the vehicle body 100 and a nozzle 342 disposed on the connecting pipe 341.
[0041] It should be noted that the connecting pipe 341 is fixedly installed at the rear of the vehicle body 100, and several nozzles 342 for spraying grass seeds are fixedly connected to the connecting pipe 341. The nozzles 342 are more even than manual sowing.
[0042] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
