Description

Technical Field

[0001] The present invention relates to the technical field of desert control engineering, and more particularly to a tool and method for desert control and grass planting. Background Art

[0002] With various attempts at desert environmental management, the windbreak and sand fixation technique of planting hay in a grid pattern (abbreviated as grass planting or grass pressing) has gradually gained acceptance in practice. To accommodate the vastness of the desert work area and reduce the workload of construction workers, research has also flourished on various types of automated equipment, particularly large-scale ones, capable of continuous and long-distance operations. These systems lay multiple parallel "grass paths" along a predetermined path, particularly a straight line. Because the initial grass paths are laid from scratch and extend over long distances, they are called "long grass paths." In contrast, the spacing between each "long grass path" is shorter, so the paths intersecting (especially perpendicular) the "long grass paths" are called "short grass paths." In other words, to form a grass grid, "short grass paths" are subsequently laid.

[0003] However, these equipment often require off-road tractors and other pulling machinery. When laying the "short grass paths," the tractor's travel mechanism is forced to frequently cross over the existing "long grass paths," resulting in ruts on both sides of the intersections that completely ruin the previous work. At this point, the tractor's ground clearance, which is an advantage for laying "long grass paths," becomes an unacceptable option for "short grass paths." Construction workers are forced to resort to manual tools, typically using shovels to force the hay into the sand by stomping on it. In scorching environments like the Xinjiang desert, where temperatures can easily reach over 30 or 40 degrees Celsius, this poses a significant threat to workers' physical exertion and safety.

[0004] On the other hand, even for the paving of "long grass roads", some labor companies or construction teams often find it difficult to introduce the above-mentioned large-scale automated equipment due to various reasons such as the working area and equipment purchase costs. Instead, they use manual tools such as shovels or even impact drills.

[0005] In summary, it is hoped that a simple, efficient and more suitable instrument for direct manual operation can be designed. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a sand control and grass planting tool that can significantly improve construction efficiency.

[0007] According to one aspect of the present invention, a tool for sand control and grass planting is provided, comprising: a lever with a pressure plate disposed between the two ends of a shaft, a bracket portion, and a rotating portion. The pressure plate has a lower edge adapted to press straw into the sand. The lever is mounted to the bracket portion via the rotating portion so as to be rotatable relative to the bracket portion about the rotating portion. The bracket portion is used to support the tool on the sand surface. This forms a force-saving lever mechanism with the rotating portion as a fulcrum and the operating length of the lever as a power arm.

[0008] Preferably, a support portion is slidably provided on the lever, and the pressure plate is mounted on the support portion via a pressure rod.

[0009] Preferably, an adjustment line is installed on the support part for pulling the support part to adjust the sliding position on the lever, and the adjustment line is constructed as a section of line extending to both ends of the lever or a ring line passing through both ends of the lever; or, a gear rack mechanism is formed between the support part and the lever.

[0010] Preferably, the pressure rod is installed on the supporting part via the mounting part, and the mounting part is arranged as a sleeve structure. The upper spring and the lower spring are respectively arranged on the upper and lower sides of the pressure rod inserted through the mounting part, and the stop pin and the stop block for spring limiting are correspondingly arranged, and the upper spring is hooked between the supporting part and the stop pin.

[0011] Preferably, a chamfered portion is formed on the lower end side of the main board portion of the pressure plate, at least on one end side of the flush lower end edge; and / or, the flush lower end edge is formed in a plurality of dispersed sections, with recessed portions between each section, and the plurality of sections form relatively blunt teeth.

[0012] Preferably, the supporting portion is configured as a sleeve sleeved on the lever, and a bayonet slot that can be shape-locked with the bracket portion is provided at one end of the sleeve facing the bracket portion; or, a limiting portion extending toward the bracket portion and capable of shape-locking with the bracket portion is installed on the supporting portion.

[0013] Preferably, the bracket portion is configured to be in the shape of a drill rod, and when the support portion and the bracket portion are in form-locked engagement, the lever can be pushed laterally to rotate around the drill rod-shaped bracket portion.

[0014] Preferably, the bracket portion is configured as a wheel with a coaxial double-wheel structure, and the lever is connected to the axle of the wheel via a rotating portion in the form of a bearing at one end side, the rotating portion is connected to the lever in a detachable manner, and at least one pressure plate is arranged along the axial direction of the lever, wherein when two pressure plates are provided, the pressure plate above the lever is offset relative to the pressure plate below.

[0015] Preferably, the pressure plate is directly fixedly connected to the lever or rigidly connected to the lever via a pressure rod; or, the lever and the pressure plate are integrally formed into a guillotine-shaped component.

[0016] According to another aspect of the present invention, a method for sand control and grass planting is provided, which uses the above-mentioned sand control and grass planting tool to press grass into the sand to form grass paths or grass grids, including the following steps: by supporting the bracket part on the sand surface, raising and lowering the lever up and down around the rotating part to realize the grass pressing operation cycle; when the bracket part is configured as a drill rod, the operating area is switched by pushing the lever to rotate horizontally around the bracket part; when the bracket part is configured as a wheel with a coaxial double-wheel structure, the grass pressing operation cycle is sequentially realized by pushing the wheels forward.

[0017] The present invention can be used for laying both short and long grass paths. It includes the following steps: supporting the support on the sandy surface and reciprocatingly raising and lowering the lever around the rotating portion to achieve a grass-pressing cycle; pushing the lever to rotate horizontally around the support to switch working areas; and pushing the wheels forward to sequentially complete the grass-pressing cycle, thereby greatly improving the working conditions of construction workers.

[0023] The following describes in detail exemplary embodiments of the present invention in conjunction with the accompanying drawings. The exemplary embodiments described below and illustrated in the accompanying drawings are intended to teach the principles of the present invention and enable those skilled in the art to implement and use the present invention in a number of different environments and for a number of different applications. Therefore, the scope of the present invention is defined by the appended claims, and the exemplary embodiments are not intended to, and should not be considered to, limit the scope of the present invention. Furthermore, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not necessarily drawn to actual scale. Regarding orientation descriptions, such as the longitudinal direction corresponding to the longitudinal length of the main body, and the orientations or positional relationships indicated as up, down, left, right, front, and back, for example, with the forward direction of the operating stroke as the front, the lifting direction can correspond to up or down, are all based on the orientations or positional relationships shown in the drawings.

Therefore, they should not be construed as limiting the scope of the present invention. Unless otherwise specified, the order of components and assembly steps and the numerical values described in the embodiments do not limit the scope of the present invention. Furthermore, any numerical range stated herein is intended to include all subranges contained therein. A numerical range expressed as "value A - value B" refers to a range that includes both endpoints A and B. Those skilled in the art will appreciate that terms such as "first," "second," and "step" in this disclosure are used solely to distinguish between different steps, devices, or modules, and do not convey any specific technical meaning or necessarily indicate a logical order between them. For example, steps two and three may be swapped or performed in parallel.

[0024] like Figure 1 As shown, a desertification control and grass planting tool according to an exemplary embodiment of the present invention is shown, including: a lever 1, a bracket part 2, a rotating part 3, a supporting part 4, a pressure rod 5, a mounting part 6, a pressure plate 7, a stop pin 8, an upper spring 9, a lower spring 10, a stop block 11, a fixing part 12, and an adjustment line 15.

[0025] In some embodiments, for example, during a grass pressing operation, a rod-shaped support portion 2, such as a drill rod, is inserted into the sand. The support portion 4 is pulled by the adjustment line 15 and adjusted to the desired position along the longitudinal direction of the lever 1. As shown by the arrow, a downward force F is applied to the other end of the lever 1, causing the lever 1 to deflect downward relative to the support portion 2 around the rotating portion 3. The force is transmitted to the pressure plate 7 connected to the fixed portion 12 via the pressure rod 5, thereby forming a labor-saving lever in which the power arm is longer than the resistance arm. Compared with directly stepping on the shovel plate, the required power can be significantly reduced, saving physical energy. In this way, the hay straw 13 can be easily pressed into the sand.

[0026] exist Figure 1Also shown is a braided rope 14 for pre-tying the hay straw 13 together. In conventional artificial grass planting operations, there are usually at least two construction workers, A and B, working together. A in the front opens the loose grass or prefabricated grass bundles and lays them forward in sequence on the sand surface, while B in the back performs the grass pressing operation. According to the present invention, A and B can stand on the two ends of the lever 1 shaft respectively. In addition to laying the grass, A can assist B in inserting the bracket part 2 into the sand and completing the adjustment of the adjustment line 15. He can also assist in supporting the bracket part 2, and B can easily complete the pressure and reverse lifting actions. Then, by re-adjusting the adjustment line 15, all the hay straw 13 on the right side of the bracket part 2 can be quickly pressed into the sand. When the grass planting operation of a row of "short grass paths" is completed and it is necessary to move to the next row, A and B can cooperate to lift the bracket part 2 out of the sand and move to the next row to repeat the operation.

[0027] Optionally, when the bracket part 2 is inserted into the sand in the middle position between the two "long grass roads", at this time, on the completed side (such as Figure 1 After the right side (also referred to as half) of the bracket 2 (shown as the right side), operator B can push lever 1 laterally, rotating it 180 degrees around the bracket 2 in a roughly horizontal plane to a mirror-symmetrical position (at which point the bracket 2 itself can also rotate), allowing the grass-pressing operation on the other side (corresponding to the left side of the bracket 2) to be performed. This effectively shortens the required length of lever 1, saving material costs and reducing the workload of long-distance transport operations. Of course, the operating end portion of lever 1 can also be designed as a wooden handle, for example, which can further reduce weight and improve operating comfort compared to a fully metal structure.

[0028] More specifically, lever 1 is connected at one end to the upper side of bracket portion 2 via a rotating portion 3, for example, mounted on a short cantilever shaft via a bearing or pin-shaped pivot connection. This essentially forms a force-saving lever mechanism with rotating portion 3 as the fulcrum, the entire length or a portion of the length of lever 1 (corresponding to the distance from the handle to bracket portion 2, collectively referred to as the usable length) as the power arm, and the distance between support portion 4 or pressure plate 7 and rotating portion 3 as the resistance arm. Here, rotating portion 3 can be configured as a pivot or a rotation support. The pressure rod 5 is preferably a linear rod to effectively transmit force and withstand pressure, and is therefore simply referred to as the pressure rod.

[0029] To accommodate rapid, continuous operation, the support portion 4 is slidably supported on the shaft of the lever 1, for example, in the form of a simple sleeve. This allows for simple control of the movement or fixation of the support portion 4 via an adjustment wire 15. This adjustment wire 15 can be threaded and wound around a wire loop provided on the support portion 4 or the pressure rod 5, extending in a linear fashion to each end of the lever 1 for pulling. Alternatively, a ring-shaped adjustment wire 15 can be provided, allowing construction worker B to pull the wire alone to adjust the position of the support portion 4.

[0030] Of course, the present invention is not limited to this, and a conventional rack and pinion type (not shown) may also be used. In this case, an upward rack is formed on the shaft of the lever 1, and the support portion 4 includes a U-shaped groove located on the lower side and a gear mounted on the upper end side of the U-shaped groove. In this case, the rack passes through the U-shaped groove cavity, and the gear is hung on the rack by gravity. During the grass pressing operation, the bottom of the U-shaped groove is pressed upward against the lower side of the shaft of the lever 1 due to the downward pressure, and does not affect the engagement of the gear on the upper side of the shaft. In this case, a small motor may be provided to adjust the position of the support portion 4 to improve the level of automation.

[0031] In some embodiments, the pressure rod 5 can be fixed to the support part 4 via the mounting portion 6 , for example, by welding, bolting, etc., to form a particularly simple rigid connection tool.

[0032] In some embodiments, the mounting portion 6 can also be configured as a sleeve structure, with an upper spring 9 and a lower spring 10 respectively mounted on the upper and lower sides of the pressure rod 5 inserted through the mounting portion 6. Furthermore, by correspondingly providing a stop pin 8 and a block 11, this can adapt to the sudden collision scenario caused by hard lumps or gravel in the sand during the grass pressing operation. In this case, during the downward pressing operation, as construction worker B accelerates to press the lever 1, the impact force generated by the sudden deceleration of the pressing plate 7 during the follow-up grass pressing process will be absorbed by the lower spring 10. This helps to reduce muscle damage to construction worker B and allows for timely clearing of obstacles through the perception of force changes. In particular, as described above, the lever 1 can rotate laterally, simultaneously driving the pressure rod 5 and the pressing plate 7 to twist in a rigid connection. This can achieve the same grass pressing effect by slightly deviating from the predetermined grass pressing position, and it is also possible to use the pressing plate 7 to clear small gravel by pulling. Furthermore, hard lumps in the sand can also be broken by continuously lifting and pressing.

[0033] On the other hand, the upper spring 9 hooked between the support portion 4 and the stop pin 8 is stretched to store energy. Conversely, during the lifting process of the lever 1, the gravity and the rebound force of the lower spring 10 act as a force buffer for the pressure rod 5 and the pressure plate 7, reduce noise, and automatically reset the pressure plate 7. In this way, by adjusting the spring arrangement according to needs, effective force transmission can be achieved at the same time.

[0034] In some embodiments, the mounting portion 6 can also be configured to be able to rock relative to the supporting portion 4 at a predetermined deflection angle, for example, by providing an insertion hole in the supporting portion 4, and forming an insertion pin on the mounting portion 6, through multiple shape locking positions between the insertion hole and the insertion pin, for example, it can also be achieved by a locking pin, and the bottom surface pressing position of the pressure plate 7 can be adaptively adjusted.

[0035] For example, in Figure 1 When the lever 1 is deflected upward or downward in the direction shown, the bottom edge of the pressure plate 7 will deviate relatively obliquely. Figure 1In the horizontal position shown in FIG. , particularly when pressing downward, uneven forces may be applied to the prefabricated straw. Preferably, chamfers (rounded corners) are formed on both edges of the bottom side of the pressing plate 7 to reduce the unwanted shearing forces caused by pulling on adjacent straws during the pressing process, and to facilitate the pressing plate 7 to cut into the sand when pressing downward.

[0036] In the above embodiment, the lever 1 can be rotated laterally to adjust the pulling position or even rotated to the opposite side. Figure 4 、 Figure 1 As shown, a bayonet slot 41 is provided at one end of the sleeve of the support portion 4 that faces the bracket portion 2. The bayonet slot 41 can be gap-fitted or tightly fitted with the rod of the bracket portion 2 with a relatively small gap, thereby substantially achieving a form lock. When it is necessary to rotate the lever 1 laterally, the support portion 4 is pulled toward the bracket portion 2 until the bayonet slot 41 engages with the bracket portion 2, thereby forming a rigid torsional connection between the lever 1 and the bracket portion 2. While ensuring that the lever 1 and the bracket portion 2 rotate laterally together, the rotating portion 3 is prevented from being damaged due to excessive force. In addition, a limiting portion such as a claw extending toward the bracket portion 2 can also be welded on the sleeve of the support portion 4 to achieve a locking function similar to the bayonet slot 41 to assist deflection, which is collectively referred to as a locking portion. In this way, the support portion 4 can generally take into account both the position adjustment of the pressure plate 7 and the rigid torsional locking effect of the lever 1.

[0037] <Modification>

[0038] In some embodiments, the support part 2 in the form of a drill rod, a fork rod, etc. can be replaced by a wheel with a coaxial double wheel structure, for example, a ground wheel commonly used in farmland transportation operations can be used as the support part 2, such as Figure 2 As shown, the lever 1 is connected to the axle of the ground wheel at one end via a rotating part 3 in the form of a bearing (such as a split connecting sleeve, two half sleeves of a bayonet connecting sleeve), because the axle itself can rotate freely in the wheels on both sides, thereby easily achieving the lifting and lowering operation of the other end of the lever 1.

[0039] Similarly, when it is desired to operate the other half of a row of "short grass paths" as described above, the wheels can be deflected to achieve a U-turn. Of course, the wheels can also be simply pushed forward directly, and the construction worker A in the front can directly press the axle to assist in stabilizing the operation. At this time, the pressure rod 5 can be directly and rigidly fixed to the lever 1. In this way, it is also convenient for mobile transportation outside of the operation, and it is convenient to use local materials, flexibly use them, and reduce costs. When grass planting is not needed, the lever 1 can be removed to restore the original function of the wheel without affecting the needs of other agricultural activities. Preferably, the rotating part 3 and the lever 1 can adopt a detachable connection method such as a pin and a slot. In this way, the rotating part 3 can be hung on the wheel axle in advance and standby. When working, the front end of the lever 1 can be inserted into the reserved slot of the rotating part 3.

[0040] Although not shown, Figure 2 In this structure, another pressure plate can be positioned above the lever 1, offset axially relative to the lower pressure plate 7, to accommodate the desired resistance arm length for different operators, providing flexibility. The pressure plate can be switched by simply rotating the lever 1 half a turn around the rotating portion 3 and flipping it to the other side. In this case, the pressure rod 5 securely connects the lever 1 to the pressure plate 7.

[0041] In some embodiments, as Figure 3 As shown, the pressing plate 7 has a chamfered portion 72 formed on the lower end side of its main plate portion 70, at least on one end side of the flush lower edge 71. The flush lower edge 71 can also be formed in a plurality of dispersed sections, with recessed portions 73 between each section. In this way, the plurality of sections are formed into relatively blunt teeth, which can reduce damage to the straw, increase the insertion force of the teeth, and reduce the resistance of some sand. In general, the main plate portion 70 is preferably a whole plate, but is not limited to this, and there is no restriction on the taper of its cross section. In an operating environment with relatively soft sand, the steel plate with a pointed bottom and thick top will not significantly affect the burying effect of sand during extraction.

[0042] In some embodiments, as Figure 5 As shown, can be omitted Figure 2 The pressure rod 5 in the middle forms a guillotine-like member by integrating the lever 1 and the pressure plate 7. The member is pivotally mounted to the bracket 2 around the mounting hole 31 of the front rotating portion. By applying force to the blade handle 33, the grass can be cut using the curved blade surface 32. In this way, the wheel diameter can be reduced to a height close to the surface of the sand, and the grass can be cut in a "guillotine-cutting" manner while the wheel is pushed forward.

[0043] In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly defined. Unless otherwise clearly defined and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Although the present invention has been described with reference to various specific embodiments, it should be understood that variations can be made within the spirit and scope of the described inventive concept. Therefore, it is intended that the present invention is not limited to the described embodiments, but will have the full scope defined by the language of the appended claims.
