Description

Technical Field

[0001] This project belongs to the field of desert control machinery, and specifically relates to an intelligent tree planting machine for planting Haloxylon ammodendron. Background Art

[0002] China is one of the countries suffering from desertification hazards. All countries in the world are suffering from desertification, and desertification has now become a global environmental problem. Not only for the areas close to desertification, it has posed serious threats and hazards to the production and life of the people, social and economic development, resources, ecological environment, etc. in the vast desertified areas of our country, and even endangered the survival of the surrounding residents, hindering the sustainable development of our country. And extreme weather such as sandstorms will reduce air quality, and the resulting air pollution will have many adverse effects on health and also increase the risk of mortality.

[0003] Due to the long-term arid state and extremely harsh conditions in desert areas, this will also greatly affect the climate conditions to a large extent. To effectively regulate the harsh climate in desert areas, afforestation is a relatively effective way. Many plants have the ability to stabilize sand dune afforestation, but the appropriate plant varieties need to be selected according to the length of the branched root system and the resistance to harsh environmental conditions. Haloxylon ammodendron is an excellent tree species for sand fixation and wind prevention in the Alxa area and for improving the harsh ecological environment of desert gobi. It is especially suitable for artificial afforestation. Cultivated Haloxylon ammodendron usually grows relatively fast, has a good effect on sand fixation and wind prevention, and can grow stably and form a Haloxylon ammodendron forest without irrigation in desert areas.

[0004] Due to the characteristics of vast land and sparse population in desert areas, the use of mechanized technology for seedling planting and afforestation is of great significance, because mechanized seedling planting and afforestation has many advantages, such as fast speed, high efficiency, high quality, low cost, etc. Mechanized seedling planting and afforestation is suitable for application in plain areas and sandy lands with inconvenient transportation, large areas and sparse population. Mechanized tree planting has been proven to be very time-saving, because machines can potentially alleviate future labor shortages. Therefore, the use of mechanized automatic equipment in the desert environment not only solves the labor problem, but also helps to reasonably allocate and utilize resources. Summary of the Invention

[0005] The present invention provides an intelligent Haloxylon ammodendron tree transplanter, which aims to solve the problems of low efficiency of manual tree planting in desert environments and the unsuitability of traditional machinery for desert greening, thereby improving land desertification and creating an oasis in the desert. In order to adapt to the harsh desert environment and the unique characteristics of sandy land, improve work efficiency, and improve the working environment of workers, the present invention designs an intelligent Haloxylon ammodendron tree transplanter. Through the design of internal mechanisms, multiple structures work together, and a control system is used to achieve remote control intelligent tree planting in the desert, the intelligence level of the Haloxylon ammodendron tree transplanter is improved, ensuring continuous operation of the machine, improving tree planting efficiency, adapting to desertified land environments and achieving large-scale tree planting, while also ensuring a high survival rate of Haloxylon ammodendron tree seedlings and saving labor.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following scheme: an intelligent planting machine for Haloxylon ammodendron, including a sand pushing device, a seedling conveying mechanism, a crank slider mechanism, a planting mechanism, a filling mechanism, a crawler chassis, a support plate, and a support frame, characterized in that: the sand pushing device is located at the front end of the intelligent planting machine for Haloxylon ammodendron, two seedling conveying mechanisms are laterally symmetrically distributed and fixed to the support plate and located on the upper side of the support plate, two planting mechanisms are connected to the crank slider mechanism and fixed to the support frame and located on the outside of the support frame, four filling mechanisms are distributed at the four corners of a square and fixed to the support plate and located on the lower side of the support plate, and four crawler chassis are fixed to the support plate and located on the lower side of the support plate.

[0007] As a further description of the above technical solution, the seedling conveying mechanism is equipped with two motors, which rotate the sprocket and drive the chain to rotate so that the seedling barrel moves at a set speed in the U-shaped track. When the seedling barrel containing the seedlings moves above the seedling drop hole, the seedlings will fall from the seedling barrel into the planting mechanism below. At this time, the motor stops and the sprocket also stops rotating, waiting for the tree planting to be completed.

[0008] As a further description of the above technical solution, the crank slider mechanism is driven by a high-torque servo motor to rotate the crank so that the slide rod drives the planting mechanism to move up and down in the vertical direction.

[0009] As a further description of the above technical solution, the two planting mechanisms are located directly below the two seedling holes, and the opening and closing of the left cone leaf and the right cone leaf are controlled by two servos. When the seedling falls into the closed cone leaf, the cone leaf is inserted down, and then the left and right cone leaves open to shape the sand pit. The seedling falls into the sand and is finally pulled up by the sliding rod. The cone leaf closes while rising, completing a planting.

[0010] As a further description of the above technical solution, the soil filling mechanism is driven by a stepping motor to rotate the soil filling wheel to gather the surrounding soil next to the seedling.

[0011] As a further description of the above technical solution, the four crawler chassis are driven by a servo motor to rotate the drive wheel to drive the crawler to move under the support of the carrying wheels and the guide wheels, thereby driving the entire tree planter to move in the desert.

[0012] The present invention has the following advantages:

[0013] 1. In the present invention, the seedling conveying mechanism has a specific U-shaped track, which can ensure the stable operation of the seedlings in the track and reduce the friction between the seedlings and the track. And multiple seedling barrels can store multiple seedlings. Coupled with chain drive, it can ensure the continuity and high efficiency of tree planting and improve the tree planting efficiency.

[0014] 2. In the present invention, the seeding mechanism and the crank-slider mechanism cooperate. The crank-slider mechanism driven by a high-torque servo motor can ensure that the seeding mechanism inserts deep enough into the sandy land and reduces the volume of the machine. The seeding mechanism shapes the sand pit by opening the tree planting cone leaves, which can prevent the quicksand from automatically filling the sand pit after it is dug out. The seeding mechanism simulates the transplanting action to plant the Haloxylon ammodendron, which can ensure that the Haloxylon ammodendron is vertically buried in the soil and improve the survival rate of the Haloxylon ammodendron.

[0015] 3. In the present invention, the filling wheels arranged in a square in the filling mechanism can fill the planting pit in all directions, and by adjusting the rotation speed of the stepping motor, the filling amount and the filling distance of the filling wheels can be changed, better controlling the planting situation of the Haloxylon ammodendron and ensuring that it can be firmly planted in the soil in different environments.

[0016] 4. In the present invention, the machine is controlled by Bluetooth, and the staff can perform remote control without entering the machine for driving, realizing intelligence and improving the working environment of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] Refer to Figure 1-4 , a Haloxylon ammodendron intelligent seeding machine includes 1, sand pushing device 2, seedling conveying mechanism 3, crank-slider mechanism 4, seeding mechanism 5, soil filling mechanism 6, crawler chassis 7, support plate 8, support frame 9, U-shaped track 10, seedling bucket 11, chain 12, seedling dropping hole 13, sprocket 14, high-torque servo motor 15, connecting rod 16, sliding rod 17, servo motor 18, left conical blade 19, right conical blade 20, soil filling wheel 21, stepper motor 22, crawler 23, driving wheel 24, carrying idler 25, guide wheel 26, servo motor 27, sliding rod frame. The sand pushing device 1 is located at the front end of the Haloxylon ammodendron intelligent seeding machine, and two seedling conveying mechanisms 2 are symmetrically distributed horizontally and fixed on the upper side of the support plate 7. Two seeding mechanisms 4 are connected to the crank-slider mechanism 3 and fixed on the outer side of the support frame 8. Four soil filling mechanisms 5 are distributed at the vertices of a square and fixed on the lower side of the support plate 7. Four crawler chassis 6 are fixed on the lower side of the support plate 7.

[0027] Furthermore, the sand pushing device 1 levels the sand and soil in the planting area.

[0028] Further, the sapling conveying mechanism 2 has a total of two tracks, and each track is equipped with thirty-eight sapling buckets 10. The sapling buckets are connected to the chain 11. After the motor drives the sprocket 13 to rotate and transmits to the chain 11, the sapling buckets will move along with the chain 11. The saplings slide on the U-shaped track 9 following the sapling buckets 10. When the sapling bucket 10 moves above the seedling dropping hole 12, the saplings in the sapling bucket 10 will fall into the left cone leaf 18 and the right cone leaf 19 in the closed state of the seeding mechanism 4 below due to gravity. At this time, the sprocket 13 stops rotating and waits for the seeding to be completed.

[0029] Further, the crank-slider mechanism 3 is driven by a high-torque servo motor 14. The connecting rod 15 rotates to drive the sliding rod 16 to move vertically downward in the sliding rod bracket 27, and the seeding mechanism 4 connected to the sliding rod 16 inserts downward into the sand for seeding.

[0030] Further, after the seeding mechanism 4 inserts into the sand, the left cone leaf 18 and the right cone leaf 19 open under the drive of the steering gear 17 to complete the shaping of the sand pit, and at the same time, the saplings fall into the sand pit due to gravity.

[0031] Further, the crank-slider mechanism 3 pulls the seeding mechanism upward under the drive of the high-torque servo motor 14, and at the same time, the left cone leaf 18 and the right cone leaf 19 close under the drive of the steering gear to catch the saplings in the next sapling bucket 10.

[0032] Further, the sprocket rotates again for the next seeding. The sapling bucket 10 is connected to the chain 11, which can ensure that the saplings regularly fall into the seeding mechanism 4 below, realizing continuous operation and improving the tree-planting efficiency.

[0033] Further, the filling wheel 20 in the filling mechanism 5 arranged in a square rotates under the drive of the stepping motor 21, and the vanes bring the sand into the sand pit to complete the filling of the soil.

[0034] Working principle: When in use, first place the saplings in the sapling bucket 10 through pre-treatment. Each time, only the entire set of sapling buckets 10 needs to be replaced. Subsequently, place the processed saplings on the sapling conveying device 2. Driven by the sprocket 13 to move the chain 11, the saplings will move with the chain and naturally fall when passing above the seedling dropping hole 12, and enter the left conical leaf 18 and the right conical leaf 19 in the closed state of the seeding mechanism 4 for temporary storage. When the vehicle travels to the designated position, the seeding mechanism 4 is driven by the crank-slider mechanism 3 and rapidly descends into the sand by the slide rod 16. When reaching the designated depth, the left conical leaf 18 and the right conical leaf 19 are quickly opened under the drive of the servo motor 17 to shape the sand pit. At the same time, the saplings will fall due to gravity into the deep pit that has been inserted and shaped. Then, the seeding mechanism 4 is lifted as the slide rod 16 rises. The left conical leaf 18 and the right conical leaf 19 are closed under the drive of the servo motor 17 during the rising process. The sprocket 13 then works again to drive the chain 11 to move, and the next sapling regularly falls into the seeding mechanism 4 again. At the same time, the soil filling mechanism 5 works, and the soil filling wheel 20 rotates driven by the stepping motor 21. The rotational movement of the wheel blades can bring the sand into the sand pit to complete the filling of the soil, ensuring that the saplings are firmly inserted into the soil and completing one tree planting. Repeat the above operations after the vehicle runs to the designated position.
