Technical Field
[0001] This utility model belongs to the field of planting tool technology, specifically relating to a grass seed spreading device for ecological restoration in mining areas. Background Technology
[0002] With the completion of ore extraction in mining areas, environmental remediation is often carried out to reduce pollution and damage to the mining area. The conventional method is to sow grass seeds for initial environmental remediation. To ensure the survival rate of grass seeds and improve the convenience of sowing, grass seeds are often sown using methods such as trellises. However, this method requires manual control of the sowing amount and the need to grab grass seeds and place them at any time, which makes placement inconvenient and may result in insufficient or excessive grass seeds in the sowing area. This is not conducive to the ecological restoration of the mining area and requires multiple replantings. Utility Model Content
[0003] The purpose of this invention is to provide a grass seed spreading device for ecological restoration in mining areas, which addresses the problems mentioned in the background art.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figure 1-4As shown, a grass seed spreading device for ecological restoration in mining areas includes a guide rod 1, which has a hollow structure. The upper end of the guide rod 1 is provided with a funnel 11 that communicates with the hollow part, and the other end of the guide rod 1 is provided with a material distributing mechanism.
[0022] The material distribution mechanism includes a storage hopper 2, an outer casing 3, a material distribution roller 4, and a rotator. The storage hopper 2 has an isosceles trapezoidal structure and its short side is connected to the guide rod 1. The outer casing 3 is connected to the long side of the storage hopper 2 and is integrally formed. The material distribution roller 4 is rotatably located inside the outer casing 3. The rotator is located between the outer casing 3 and the upper side of the guide rod 1 and is connected to the material distribution roller 4 for transmission.
[0023] The side of the material distribution roller 4 has a material distribution groove 41 connected end to end along its curved surface. After the material distribution groove 41 is unfolded, its groove line trajectory is a sine curve trajectory. Several material separation plates 42 are provided at intervals inside the material distribution groove 41. The lower end of the outer casing 3 has a material outlet 31 corresponding to the material distribution groove 41.
[0024] During grass seed sowing, workers load grass seeds into guide rod 1 through funnel 11. The hollow structure of guide rod 1 guides the grass seeds into storage hopper 2, where the seeds are collected and stored. Workers then drive distributing roller 4 via a rotary actuator. Due to the obstruction of distributing roller 4 and storage hopper 2 by outer sleeve 3, the grass seeds in storage hopper 2 fall into distributing groove 41 on the side of distributing roller 4 as it rotates. Since distributing groove 41 is connected end-to-end and its unfolded groove trajectory is a sinusoidal structure, the opening of distributing groove 41 corresponding to storage hopper 2 varies and is only one segment, working in conjunction with separating plates 4. 2. As the grass seeds are carried by the distribution trough 41 and rotate with the distribution roller 4, the grass seeds are blocked to prevent them from slipping along the gaps until they fall from the distribution trough 41 and the discharge port 31. With the extension of the guide rod 1, the grass seeds can be sown into the designated position more accurately. Compared with the common single guide tube structure and some guide tubes with flip-tops, this can control the number of grass seeds sown at one time, avoiding waste caused by sowing too many seeds at one time and competition for nutrients with subsequent grass plants. At the same time, it does not require the filling of grass seeds for each sowing, and has a certain storage capacity, making it more convenient for grass seed sowing and use.
[0025] The guide rod 1 has a 7-shaped structure, and the lower end of the upper bent part of the guide rod 1 is provided with a handle 12; this makes it easier for staff to hold the guide rod 1.
[0026] The rotating device includes a handle 5, a cable 51, a winding reel 52, and a coil spring 53. The handle 5 is slidably connected to the guide rod via a collar, and the collar is slidably connected to the guide rod 1 via a guide rib. The winding reel 52 is located on the side of the outer casing 3 and is rotatably connected to the outer casing 3 and the material distribution roller 4 via a rotating shaft. The coil spring 53 is sleeved on the rotating shaft and its outer end is connected to the winding reel 52. The inner end of the coil spring 53 is connected to the outer casing 3. The two ends of the cable 51 are connected to the handle 5 and the winding reel 52 respectively, and the cable 51 is wound around the winding reel 52.
[0027] In the initial state, under the winding and tension of the coil spring 53, the distribution roller 4 can be controlled to not rotate automatically, while the cable 51 is kept pulled. That is, the winding wheel 52 winds up the cable 51. When sowing, the handle 5 is pulled upward. At this time, the handle 5 drives the cable 51 to be released from the winding wheel 52, thereby driving the winding wheel 52 to rotate. The winding wheel 52 then drives the distribution roller 4 through the rotating shaft. The distribution groove 41 section on the distribution roller 4 passes through the discharge port 31 in sequence, thereby discharging the grass seeds previously carried and stored in the distribution groove 41. At the same time, the coil spring 53 is tightened by the traction tension of the winding wheel 52.
[0028] After single-point sowing is completed, the handle 5 is released. At this time, the coil spring 53 resets through its own elastic tension, which in turn drives the winding wheel 52 to reset. The winding wheel 52 then winds up the cable 51 and drives the material distribution roller 4 to reset, thus preparing for the next sowing.
[0029] Both the lower part of the guide rod 1 and the storage hopper 2 are made of transparent plastic; this makes it easy for staff to observe the remaining grass seeds in the storage hopper 2 and replenish the grass seeds in time.
[0030] The guide rod 1, the storage hopper 2 and the outer casing 3 are all provided with wire lugs 54 that are connected to the cable 51. The cable 51 slides through the wire lugs 54. This can limit and guide the cable 51, making the equipment look simpler.
[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
