[0029] The specific construction process of step (4) is that: a plurality of the inner seed moisture and temperature preservation composite blocks are stacked in the back of the carriage, the seeding personnel sit on the seat arranged in the back of the carriage, take the inner seed moisture and temperature preservation composite blocks and place them into the rear end of the three guide sliding grooves, the inner seed moisture and temperature preservation composite blocks automatically slide forward along the guide sliding grooves due to the low front and high rear inclination of the guide sliding grooves, and fall into the fixed discharge pipe when sliding to the front end, the electric push rod is elongated, the limiting plate blocks the forward sliding of the next inner seed moisture and temperature preservation composite block, the vertically falling inner seed moisture and temperature preservation composite block is guided by the movable discharge pipe, and then falls onto the land raked by the harrow, the lower end of the inner seed moisture and temperature preservation composite block is stuck into the soil, then when the truck body travels a distance equal to the distance from the movable sleeve to the pressing column, the inner seed moisture and temperature preservation composite block is just located below the pressing column, the truck body is parked for 3-5s, the sixth lifting oil cylinder drives the pressing plate to move downward, the lower end surface of the pressing column presses the inner seed moisture and temperature preservation composite block into the soil to a proper depth, when the truck body is parked, the electric push rod is retracted, the next inner seed moisture and temperature preservation composite block slides forward and falls onto the soil surface through the fixed discharge pipe and the movable discharge pipe, and then the truck body continues to travel, and the feeding and pressing are cyclically performed, and steps (1)-(4) are intermittently performed.

When working, the driver drives the truck body to perform ecological restoration (to improve the poor land in the alpine region), and the specific working steps of the application are as follows:

[0032] The beneficial effects of the main components and structures of the application are as follows:

[0033] 1) The provided debris pickup device picks up stones or other garbage on the land that needs to be repaired, avoiding being buried in the soil during plowing and affecting the performance of the soil. The first lifting oil cylinder drives the front side of the guide plate to move up and down, and the height can be adjusted according to different terrain. The baffle prevents the stones or garbage from falling during the rear conveying process.

[0034] When there are more weeds on the land, if the weeds are not removed, it will not only affect the subsequent plowing operation (weeds will wrap around the share plow), but also affect the smooth pressing of the subsequent embedded seed moisture and temperature preservation composite block into the soil.

[0035] The combustion shell covers the weeds, and the lower edge of the combustion shell has a ventilation gap with the ground. The liquefied gas is ignited to assist combustion, so that the weeds burn in the combustion shell. The structure composed of the combustion shell and the dust falling cylinder forms a chimney effect, and the smoke gas is automatically discharged from bottom to top. The dust in the smoke gas is separated and removed in the dust falling cylinder. The smoke gas without dust is discharged into the atmosphere. The spray nozzle of the spray dust removal device atomizes clean water and sprays the upward moving smoke gas. The smoke dust carried in the smoke gas falls automatically by gravity when it meets the mist water, realizing separation from the smoke gas. The rising speed of the smoke gas is reduced under the blockage of the smoke cap, which helps to improve the dust removal effect. The uniform flow guide plate separates the smoke gas upward and the sewage downward. The smoke gas enters the dust falling cylinder upward through the ventilation hole. Since the ventilation hole is arranged on the convex ridge between the adjacent two flow guide grooves, the sewage after purifying the smoke gas can be prevented from falling through the ventilation hole. The mist water falls into the flow guide groove of the uniform flow guide plate and converges along the flow guide groove. Through the water falling gap, it flows into the converging cylinder, and then flows downward through the drain pipe. Finally, it flows to the soil surface through the water spraying holes at the bottom of the water spraying pipe. The orderly and controllable incineration of weeds in the combustion shell eliminates the need for manual weed removal, reducing labor intensity and improving incineration efficiency and effect. It not only reduces air pollution caused by dust after burning, but also avoids fire hazards and kills pests on the soil surface. After plowing, the wood ash is turned into the ground, which improves the soil structure, improves soil fertility, promotes plant growth, levels the ground, and improves seeding quality.

[0036] The wood ash is turned into the ground by plowing, which improves the soil structure, improves soil fertility, promotes plant growth, levels the ground, and improves seeding quality.

[0037] The plow and rake device is adjusted in height by the fourth lifting oil cylinder, and stable and reliable support force is provided by the first and second inclined support positioning oil cylinders. The vibrating rake uses a vibrating motor to vibrate the lower plate and rake pins. A number of springs provide good connection and rebound effect. The flexible protective cloth prevents soil from entering the lower plate and affecting the normal working state of the spring and vibrating motor.

[0038] Because the soil in the high-cold region is poor and the temperature is low, if the germination rate of the plant seeds is to be improved during planting, the seeds need to be preserved for soil and heat, and the inner seed soil and heat preservation composite block is specially designed, the outer part adopts a degradable plastic net shell, the inner part is filled with a breathable loose mixture of nutrient soil and crushed straw, and a seed placing groove is preset in the center, different plant seeds can be placed in the seed placing groove, and then the upper port of the seed placing groove is blocked by the breathable loose mixture, so that good heat preservation and ventilation effects are achieved. Meanwhile, a degradable plastic bag is arranged in the breathable loose mixture, the degradable plastic bag is filled with nutrient solution (mainly water), and after being planted in the soil, the nutrient solution is slowly dripped into the breathable loose mixture through capillary holes, so that the moisture and nutrients around the seeds are maintained. The lower part of the inner seed soil and heat preservation composite block is a conical body with a thick upper part and a sharp lower part, which is convenient and easy to plant (press) into the soil. The seeds are planted in the prefabricated block (inner seed soil and heat preservation composite block) with heat preservation, soil preservation and fertilizer preservation, which is suitable for the climate characteristics of the high-cold region and greatly improves the germination and emergence rate.

[0039] The guide chute is formed by combining a left vertical baffle, a right vertical baffle, a left inclined baffle and a right inclined baffle, the left vertical baffle and the right vertical baffle limit the left and right positions of the inner seed soil and heat preservation composite block, the left inclined baffle and the right inclined baffle have a small contact area with the inner seed soil and heat preservation composite block, and are easy to automatically slide downward by gravity and the inclined guide chute. The electric push rod drives the limiting plate to limit the downward sliding inner seed soil and heat preservation composite block, so as to ensure that the inner seed soil and heat preservation composite blocks are spaced apart and fall.

[0040] The fifth lifting oil cylinder drives the movable downpipe to move downward, plays a guiding role, and ensures that the conical body with a thick upper part and a sharp lower part falls onto the soil first. The height of the lower end surface of the movable downpipe and the surface of the soil is slightly greater than the height of the inner seed soil and heat preservation composite block, so that the movable downpipe is prevented from touching the inner seed soil and heat preservation composite block falling onto the soil when moving forward.

[0041] The distance between the center line of the pressing column and the center line of the movable downpipe is the plant spacing, and the distance between the center lines of the left and right adjacent two movable downpipes is the plant row spacing.

[0042] The rear ends of the three guide chutes are located on the front side of a seat, that is, one person is responsible for putting the inner seed soil and heat preservation composite blocks into the three guide chutes at the same time.

[0043] The seventh lifting oil cylinder controls the position adjustment of the covering plate in the height direction, and the third inclined support positioning oil cylinder supports and positions the covering plate when the covering process is resisted.

[0044] The truck body (marketable) of the present application is also provided with a diesel engine, a generator, a battery pack and a hydraulic station to provide electric energy and hydraulic power for the normal operation of various devices. When there are no stones or other garbage on the land, the first lifting oil cylinder can be used to lift the guide plate, and the belt conveyor can be closed. When there are no large amount of weeds on the land, the ignition system of the closed type weed burning device can be closed, and only the water pump is opened to sprinkle water on the soil.

[0045] In summary, the present application has the advantages of scientific principle, completion of multiple tasks in one trip, installation of various devices on the truck body, ecological restoration of the soil by driving the truck body, reduction of manual labor intensity, and great improvement of production efficiency. After plowing and harrowing, the built-in seed moisture and temperature preservation composite block is implanted to provide a loose, breathable, temperature and moisture preserving environment for the seeds, greatly improving the seed germination rate.

The first and second inclined support positioning cylinders also extend and rotate downwards. After the moldboard plow extends into the soil to a certain depth, the fourth lifting cylinder stops extending. At the same time, the first and second inclined support positioning cylinders maintain constant support for the plow frame. As the truck body moves, the moldboard plow turns over the land after weeding. Then, under the vibration of the vibrating motor, the lower plate and harrow nails are driven to vibrate, breaking up and flattening the large clods of soil after turning over.

8. The method for soil ecological restoration and plant cultivation in high-altitude and cold regions according to claim 7, characterized in that: Step (5) The specific construction process is as follows: the seventh lifting cylinder drives the soil covering plate to move downward, and the third inclined support positioning cylinder also extends and rotates downward until the lower side of the soil covering plate extends into the soil by 2-5cm. Then the seventh lifting cylinder stops extending, and the third inclined support positioning cylinder provides constant support for the soil covering plate. As the truck body moves, the soil covering plate presses into the groove above the built-in seed moisture-retaining and heat-insulating composite block in the soil and attaches soil. At the same time, the land is compacted to a certain extent to keep the entire land flat.
