Patent Description:
With the rapid development of mineral mining technology, more and more abandoned mines are left behind after the completion of mineral mining.

After mining, the bedrock is exposed, especially in the case of high and steep slopes, rocky gravel slope surfaces would be formed after long-term weathering, by which it is difficult for soil conservation and which cannot provide good site conditions for plant growth, resulting in low survival rate of seedlings. A single herb community are prone to form after treatment, and it is impossible to restore the vegetation diversity of the mountain. In the case of the single herb community, the infection rate of pests and diseases will inscrease, which results in the increased management and maintenance cost.

<CIT> discloses a slope restoration method, which comprises: (<NUM>) pretreating a slope surface so that the concave-convex degree per linear meter of the pre-treated slope surface does not exceed ±<NUM> to <NUM> on average; (<NUM>) hanging a hard protective net on the pre-treated slope surface, the distance between the hard protective net and the slope surface being <NUM> to <NUM>, and the diameter of the holes in the hard protective net being <NUM> to <NUM>; and (<NUM>) spraying a loam-like matrix on the slope surface where the hard protective net is hung, the loam-like matrix comprising plant seeds, the mass of the plant seeds in the loam-like matrix being no less than <NUM>/m2 and the plant seeds being calculated according to the mass ratio of tree seeds: shrub seeds: herbaceous seeds, as <NUM>-<NUM>:<NUM>-<NUM>:<NUM>-<NUM>.

Trees grow slowly, is deeply rooted, and can survive the winter. After the shrubs wither in winter, the trees replace the shrubs to anchor the loam-like material, thereby further improving the fixation effect on the loam-like material and soil, so as to improve the survival rate of the shrubs after winter, and in turn improve the survival rate of all plants and increase plant diversity. With the help of soaking, the pests and diseases of seeds can be reduced, the survival rate of plants after the plant seeds are planted can be improved, and the germination efficiency of seeds can be improved.

The application will be described in further detail below with reference to accompanying drawings <NUM>-<NUM>.

A method for ecological restoration of mine vegetation with loam-like material includes the following steps:.

After the completion of the soaking, sowing seeds on the second layer of loam-like material. In the case that shrubs are planted on the second layer of loam-like material, the shrubs grow faster and take root faster, such that the surface soil layer can be quickly anchored and fixed, which reduces soil erosion and improves the survival rate of other plants. In the case that trees are planted on the second layer of loam-like material, there should be gaps between adjacent trees when planting trees, which is convenient for trees to take root and reduce the competition for nutrients between trees. The trees are deeply rooted, which can better anchor and fix the soil layer, so as to further reduce soil and water erosion, and improve the survival rate of plants.

The growth speed of trees is different from that of shrubs. Shrubs grow faster, but they are easy to die in winter. The dead shrubs form food for the slow-growing trees, so that the trees can get sufficient nutrients when growing up, which accelerates the growth efficiency of the trees and improves the survival rate of trees. After the trees grow up, the soil layer is fixed by the trees, and nutrients are not easily lost. Shrubs can easily sprout and grow in spring. A new cycle is started.

Referring to <FIG> and <FIG>, the embodiment of the present application further discloses a proportioning equipment. The proportioning equipment includes a plurality of soaking barrels <NUM> and a stirring barrel <NUM>. The side wall of each soaking barrel <NUM> is penetrated by a discharge hole <NUM>.

The first end of the conveying pipe <NUM> is fixed on the outer wall of the soaking barrel <NUM> and is in communication with the discharge hole <NUM>. The second end of the conveying pipe is in communication with the stirring barrel <NUM>. After the plant seeds are soaked in the soaking barrel <NUM>, they are transported to the stirring barrel <NUM> through the conveying pipe <NUM>. The plant seeds conveyed from different soaking barrels <NUM> are stirred and mixed in the stirring barrel <NUM> to facilitate sowing.

Referring to <FIG> and <FIG>, an adjustment assembly <NUM> is provided on the outer wall of the soaking barrel <NUM>. The adjustment assembly <NUM> includes an adjustment ring <NUM> and a transmission wheel <NUM>. The outer wall of the soaking barrel <NUM> is configured with an annular chute <NUM>. The adjustment ring <NUM> is arranged in the chute <NUM>. The adjustment ring <NUM> is penetrated by a throughhole <NUM>. The top surface of the adjustment ring <NUM> is integrally formed with transmission teeth. The transmission wheel <NUM> is arranged in the chute <NUM>. The transmission wheel <NUM> is a gear. The transmission wheel <NUM> is meshed with the transmission teeth. A first driving motor <NUM> is fixed on the outer wall of the soaking barrel <NUM>, the output shaft of the first driving motor <NUM> is coaxially and fixedly connected to the transmission wheel <NUM>. The first driving motor <NUM> drives the transmission wheel <NUM> to rotate, which in turn drives the adjustment ring <NUM> to rotate. During the rotation of the adjustment ring <NUM>, the throughhole <NUM> and the discharge hole <NUM> are gradually communicated. By controlling the communication area between the throughhole <NUM> and the discharge hole <NUM>, the discharge speed of seeds in the soaking barrel <NUM> is controlled. By controlling the discharge speed of seeds in different soaking barrels <NUM>, the proportioning of plant seeds is facilitated.

Referring to <FIG> and <FIG>, the outer wall of the soaking barrel <NUM> is provided with an opening and closing assembly <NUM>. The opening and closing assembly <NUM> is arranged in the conveying pipe <NUM>. The opening and closing assembly <NUM> includes a lifting plate <NUM>, a guide rod <NUM> and a lifting screw rod <NUM>.

During the gradual communication between the adjustment ring <NUM> and the discharge hole <NUM>, the initial conveying speed of the seeds in a plurality of soaking barrels <NUM> is the same. When the conveying speed of the seeds in the soaking barrels <NUM> no longer changes, the conveying speed of the seeds in the plurality of soaking barrels <NUM> are no longer the same, which leads to errors in the proportion of the plant seeds at the beginning. After the lifting plate <NUM> is attached to the outer wall of the adjustment ring <NUM> and the adjustment ring <NUM> is adjusted, the lifting plate <NUM> rises, to connect the throughhole <NUM> with the conveying pipe <NUM>, so that the initial conveying speeds of the plant seeds are different from each other, thereby improving the accuracy of proportion of plant seeds.

When the lifting plate <NUM> rises or sinks, it can drive the driven block <NUM> to rise or sink, thereby driving the first piston block <NUM> to slide in the pressure regulating cavity <NUM>. When the first piston block <NUM> rises in the pressure regulating cavity <NUM>, the air pressure in the pressure regulating cavity <NUM> increases, so that the air in the pressure regulating cavity <NUM> flows toward two installation cavities <NUM>, therefore, the air pressure in the installation cavities <NUM> increases, so that the second piston block <NUM> slides upward. On the contrary, when the lifting plate <NUM> sinks, the pressure in the pressure regulating cavity <NUM> decreases, so that the second piston block <NUM> is driven to slide downward.

Referring to <FIG> and <FIG>, the bottom surface of the adjustment ring <NUM> is provided with locking teeth <NUM>. The inner wall of the chute <NUM> facing the locking teeth <NUM> is configured with an aperture <NUM>. A slider <NUM> is arranged in the aperture <NUM>. One end of slider <NUM> away from the adjustment ring <NUM> is fixedly connected to the second piston block <NUM>.
