Description

Technical Field

[0001] This invention relates to a fully automatic grass pressing machine, belonging to the field of desert control technology. Background Technology

[0002] In the field of desertification control and ecological restoration, straw pressing machines are an important type of equipment used to lay and fix straw and other plant materials on the desert surface to prevent wind erosion and stabilize sand dunes. However, straw pressing machines currently on the market have many problems, which seriously affect their effectiveness and efficiency in practical applications.

[0003] First, existing straw pressing machines are significantly insufficient in terms of pressing depth. Due to the soft nature of the desert surface, straw needs to be pressed into the sand at a certain depth to be effectively fixed and prevented from being blown away by the wind. However, existing straw pressing machines often only press the straw onto the surface of the sand, making the straw easily blown away by the wind, thus greatly reducing the effectiveness of windbreak and sand fixation. Second, these straw pressing machines are generally large in size, not only occupying a lot of space during transportation and storage, but also being inconvenient to operate in the complex terrain of the desert, resulting in poor flexibility. In addition, high operating resistance is also a major drawback of existing straw pressing machines. Due to the special characteristics of the desert surface, the machine needs to overcome significant resistance during its movement, which not only increases the machine's energy consumption but also leads to low operating efficiency. The high fuel consumption problem further highlights the energy efficiency issue of existing straw pressing machines, increasing operating costs and limiting their application in large-scale desertification control projects. Finally, the excessive resistance of directly pressing the straw into the sand makes the machine prone to malfunctions during operation, further reducing construction efficiency. Summary of the Invention

[0004] To address the problems of existing straw pressing machines, such as the need for manual assistance in laying straw, insufficient pressing depth, poor quality, and low construction efficiency, this invention aims to provide a fully automatic straw pressing machine. Through optimized design, it solves the above problems, improves the working efficiency and quality of straw pressing machines in desert environments, and provides a more efficient and reliable solution for desertification control.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fully automatic straw pressing machine, comprising: The hay hopper is a cylindrical structure with openings at the top and bottom, used to hold straw; A handrail, which is located at the rear of the hopper, is used to control the forward direction of the hopper; The grass-pulling wheel is movably mounted inside the grass hopper via a rotating shaft and is driven by a power mechanism located at the rear of the grass hopper. The grass-pulling wheel is used to drive the grass hopper forward, poke the straw inside the grass hopper, and press down the straw. The grass-clamping wheels are connected in series at equal intervals on multiple rotating shafts parallel to the rotating shaft of the grass-pulling wheel, and work together with the grass-pulling wheel to pry the straw in the straw hopper. A grooving cutter is positioned on the front side of the fodder hopper and is used to create grooves in the desert as the fodder hopper moves forward. The grass pressing wheel is coaxially arranged with the grass pulling wheel. The grass pressing wheel is located directly behind the grooving knife. The grass pressing wheel presses the straw on the desert ground down by the grass pulling wheel and crushes it into the groove plowed by the grooving knife.

[0006] Furthermore, there are two grass-removing wheels, and the grass-pressing wheel is located in the middle of the two grass-removing wheels. The diameter of the grass-pressing wheel is slightly smaller than the diameter of the grass-removing wheel.

[0007] Furthermore, the grass-removing wheel is a thin wheel structure with teeth on its circumference, including a small-tooth grass-removing wheel and a large-tooth grass-removing wheel. The small-tooth grass-removing wheel has a large number of teeth and small tooth grooves, while the large-tooth grass-removing wheel has a small number of teeth and large tooth grooves. The two small-tooth grass-removing wheels are symmetrically arranged on both sides of the pressing grass wheel, and the two large-tooth grass-removing wheels are symmetrically arranged on the outer side of the small-tooth grass-removing wheel. The diameter of the large-tooth grass-removing wheel is smaller than the diameter of the pressing grass wheel.

[0008] Furthermore, two grass-burying blades are symmetrically arranged at the lower part of the grass hopper. The lower end of the grass-burying blades is turned inward, and as the grass hopper moves forward, they press the grass-pressing wheel into the grooves on both sides of the straw for scraping and burying.

[0009] Furthermore, the power mechanism includes an engine, a gearbox, a belt, and a pulley. The engine is mounted on the frame between the hay hopper and the handrail. The engine is powered to the power output end of the gearbox. The power output end of the gearbox is powered to the pulley mounted on the rotating shaft of the hay-reeling wheel via a belt.

[0010] Furthermore, the handrail has two operating levers that are shaped like an outward V-shape. The operating levers are equipped with a throttle cable and switch for controlling the engine and a gear lever for controlling the gearbox speed change.

[0011] Furthermore, the multiple grass-gripping wheels are respectively mounted on three rotating shafts, wherein, One of the aforementioned rotating shafts is located on the upper rear side of the rotating shaft of the straw-removing wheel, and straw is fed in by cooperating with the straw-clamping wheel and the straw-removing wheel; The other two shafts are located on the lower front side of the rotating shaft of the straw-pulling wheel, and the straw is discharged by the cooperation of the straw-clamping wheel and the straw-pulling wheel.

[0012] Furthermore, the number of grooving blades is two, and the number of grass-pulling wheels and grass-pressing wheels set in the grass hopper is also doubled accordingly.

[0013] Furthermore, the grooving knife can be replaced by a grooving wheel, which, under the push of the hay hopper, transforms the sliding friction grooving between the grooving knife and the desert ground into rolling friction grooving.

[0014] Furthermore, a protective frame is provided on the outer side of the slotted wheel to prevent accidental injury.

[0015] Furthermore, a balancing wheel is installed in the bottom bracket of the engine. The rotation shaft of the grass-removing wheel is connected to the drive shaft of the balancing wheel via a sprocket and chain. The balancing wheel plays a role in assisting forward movement and maintaining balance.

[0016] Compared with the prior art, the present invention has the following beneficial effects.

[0017] 1. This invention, by setting a grooving knife (or grooving wheel) to pre-groove the desert surface, and through the synergistic action of the straw-pulling wheel and the straw-pressing wheel, can accurately press the straw into the pre-cut grooves, and then use a straw-burying knife to scrape and bury the straw, ensuring that the straw is firmly fixed in the desert. This significantly improves the depth and quality of straw pressing, effectively enhances the windproof and sand-fixing effect of the straw, and reduces the risk of the straw being blown away by the wind.

[0018] 2. This invention's fully automatic straw compaction machine completely replaces manual labor, achieving fully automated construction. It automatically lays and compacts the straw without manual assistance, significantly improving construction efficiency. Simultaneously, the optimized power mechanism and transmission system allow the machine to move more smoothly in the desert, reducing running resistance and further enhancing work efficiency, enabling the rapid completion of large-scale desertification control work.

[0019] 3. The grass-pressing machine of this invention emphasizes compactness and lightweight design. Through the rational layout of its components, the machine's size is reduced, making it easier to transport and store, and particularly suitable for operation in complex terrains such as deserts. Furthermore, the optimized power system and transmission efficiency reduce energy consumption, fuel consumption, and operating costs, while also minimizing environmental pollution.

[0020] 4. This invention employs a combination design of multiple straw-pulling and straw-pressing wheels, along with the auxiliary function of straw-clamping wheels, making the straw conveying and compaction process more stable and reliable. Simultaneously, the optimized mechanical structure and power transmission system reduce the machine's failure rate during operation, improve its stability and reliability, and extend its service life.

[0021] 5. The grass pressing machine of this invention can flexibly adapt to various working scenarios by adjusting the depth and width of the grooving blade (or grooving wheel), as well as the parameters of the grass pulling wheel and the grass pressing wheel, according to different desert terrains and operational requirements. It has strong adaptability and can be widely used in different types of desert management projects. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to specific embodiments.

[0034] like Figures 1-9 As shown, the working process of this invention is as follows: I. Preparations before work The operator first pushes the fully automatic straw pressing machine to the desert work area, ensuring the machine is placed on a flat and relatively stable sand surface. Next, the upper opening of the straw hopper 1 is opened, and an appropriate amount of straw is evenly placed into the hopper. The amount of straw filling needs to be determined based on the work area and the required thickness, generally 70% to 80% of the hopper's volume is appropriate. Too much straw will cause overloading the machine, while too little will affect work efficiency. The operator then checks the throttle cable, switch 12, and gear lever 13 on the handle 2 to ensure they are in normal working order. The operator also ensures there is sufficient fuel in the engine 8's fuel tank, checks the lubricating oil level in the gearbox 9, and inspects all connections for looseness or damage. Any abnormalities must be repaired promptly.

[0035] II. Start-up and Progress The operator grips the handle bar 2 and starts the engine 8 via the throttle cable and switch 12. After starting, the engine 8's power is reduced by the reduction gearbox 9 and transmitted to the pulley 11 on the rotating shaft of the straw-pulling wheel 3 via the belt 10, thus driving the straw-pulling wheel 3 to rotate. As the straw-pulling wheel 3 rotates, the straw hopper 1 begins to move slowly forward under its drive. The operator controls the direction of the straw hopper 1 using the handle bar 2, guiding it along the predetermined laying route. At this time, the grooving knife 5 (or grooving wheel 14) located at the front of the straw hopper 1 begins to work, pre-grooving the desert to prepare for the laying of straw. As the grooving knife 5 moves forward, its blade cuts into the sand surface, forming a groove with a certain depth and width. The depth can be adjusted according to the straw laying requirements, generally 5-10 cm, and the width matches the width of the laid straw. If the grooving wheel 14 is used instead of the grooving blade 5, the grooving wheel 14 rolls under the push of the hay hopper 1, changing the original sliding friction grooving between the grooving blade 5 and the desert ground into rolling friction grooving. This method can effectively reduce the resistance and damage to the desert surface during the grooving process, and improve grooving efficiency and quality. The bottom bracket of the engine 8 is equipped with a balancing wheel, and the rotating shaft of the hay-removing wheel 3 is connected to the drive shaft of the balancing wheel via a sprocket and chain. The balancing wheel plays a role in enhancing power assistance for forward movement and balance.

[0036] III. Straw manipulation and pressing As the hay hopper 1 advances, the teeth on the hay-reeling wheel 3 begin to function during rotation. The small-toothed and large-toothed hay-reeling wheels work together. The small-toothed hay-reeling wheels, with their numerous teeth and small grooves, can better move the straw, allowing it to smoothly enter the gap between the hay-reeling wheel 3 and the clamping wheel 4 from the hay hopper 1. The large-toothed hay-reeling wheels, with fewer teeth and larger grooves, are mainly used to press the straw down, pressing it against the desert surface. Two small-toothed hay-reeling wheels are symmetrically positioned on either side of the pressing wheel 6, and two large-toothed hay-reeling wheels are symmetrically positioned outside the small-toothed hay-reeling wheels. This arrangement makes the straw movement more even and stable during the moving and pressing process. While the straw-pulling wheel 3 is pulling the straw, it also drives the straw-clamping wheel 4 to rotate. The straw-clamping wheel 4 is set on three rotating shafts. One of the rotating shafts is set on the upper rear side of the rotating shaft of the straw-pulling wheel 3, and the straw-clamping wheel 4 works with the straw-pulling wheel 3 to feed the straw. The other two rotating shafts are set on the lower front side of the rotating shaft of the straw-pulling wheel 3, and the straw-clamping wheel 4 works with the straw-pulling wheel 3 to discharge the straw, further ensuring that the straw can be smoothly transported from the straw hopper 1 to the desert surface.

[0037] IV. Straw compaction and burial After the straw is pressed down onto the desert surface by the straw-pulling wheel 3, the straw-pressing wheel 6, coaxially mounted with the straw-pulling wheel 3, begins to work. Located directly behind the grooving blade 5, the straw-pressing wheel 6 has a diameter slightly smaller than that of the straw-pulling wheel 3, allowing it to precisely press the straw into the grooves created by the grooving blade 5. The pressing action of the straw-pressing wheel 6 ensures the straw is firmly bonded to the desert surface, preventing it from being blown away by the wind. Simultaneously, two symmetrically positioned burying blades 7 at the bottom of the straw hopper 1 begin to function. The lower ends of the burying blades 7 curve inwards, scraping and burying the straw on both sides of the grooves pressed into the sand by the straw-pressing wheel 6 as the straw hopper 1 moves forward. The burying blades 7 scrape up sand from the desert surface, covering both sides of the straw, further securing it and forming a stable straw strip on the desert surface. This effectively reduces wind and water erosion, playing a role in windbreak and sand fixation.

[0038] V. Work completed After the straw laying work in the designated area is completed, the operator turns off the engine 8 via the throttle cable on the handle 2 and switch 12 to stop the machine. Then, the remaining straw is removed from the straw hopper 1, and the machine's components are inspected for damage or abnormalities. If necessary, repairs and maintenance are performed promptly. Finally, the fully automatic straw press is pushed to the storage location and stored properly for future use.

[0039] Through the above process, the fully automatic straw pressing machine can efficiently and stably complete the straw laying work in the desert, providing an effective technical means for desert management and ecological restoration.

[0040] In summary, each component technical solution involved in this invention may have multiple shapes, including but not limited to the structures described above. All technical solutions related to this technology should be within the scope of this design concept.
