Description

Technical Field

[0001] The invention relates to the technical field of desertification control equipment, in particular to a windbreak and sand-fixing grass block paving device. Background Art

[0002] As one of the hottest topics in contemporary environmental governance, desertification control continues to be a work in progress. Compared to manual sand fixation, mechanical sand fixation improves efficiency, reduces costs, and is more suitable for harsh desert environments. Grass grids have proven to be the most effective method for sand fixation. Grass grids are constructed by laying straw on sand and mechanically pressing them into the soil from the center to a depth of 20 to 25 cm, leaving 10 to 15 cm exposed above the sand surface. These grids form a 1 m x 1 m square grid. However, the woven grass grids are relatively light, making precise control of each grid's placement difficult when using mechanical straw paving. This can easily lead to overlapping straw blocks and large gaps between them, significantly impacting the effectiveness of the straw grid and weakening the effectiveness of sand control.

[0041] Figure 1 The present invention is shown in an embodiment of the present invention. For ease of description, the accompanying drawings only show structures related to the embodiment.

[0042] See also Figure 1 The windbreak and sand-fixing grass block paving device 10 in a preferred embodiment of the present invention includes a vehicle body 100, a trenching device 200, a conveying device 300 and a placing device 400.

[0043] The vehicle body 100 has a moving function. The moving direction of the vehicle body 100 is a first direction 20. The vehicle body 100 has a loading station 110 and a gripping station 120 spaced apart along a second direction 30 perpendicular to the first direction 20. Therefore, when the windbreak and sand-fixing grass block laying equipment is located on a horizontal surface, both the first direction 20 and the second direction 30 are horizontal. If the first direction 20 is the front-to-back direction of the vehicle body 100, the second direction 30 is the left-to-right direction of the vehicle body 100.

[0044] The trenching device 200 is mounted on the bottom of the vehicle body 100 and is used to dig up the ground sand to form a trench as the vehicle body 100 moves. When the vehicle body 100 moves in the first direction 20, the trenching device 200 digs up the ground sand to form a trench, and digs the sand to both sides of the trench, with the trench's trajectory aligning with the vehicle body 100's movement trajectory.

[0045] The conveying device 300 is mounted on the vehicle body 100 and is used to sequentially transfer the grass blocks from the loading station 110 to the grabbing station 120. The conveying device 300 may be a robotic arm, a conveyor belt mechanism, or other automated structure that can sequentially transfer the grass blocks from the loading station 110 to the grabbing station 120.

[0046] The delivery device 400 includes a lifting assembly 410 and a mechanical claw structure 420 mounted on the lifting assembly 410. The lifting assembly 410 is mounted on the vehicle body 100 and is used to drive the mechanical claw structure 420 to rise and fall along a plane perpendicular to the second direction 30. The mechanical claw structure 420 is used to catch and hold grass blocks that fall from the grabbing station 120 when passing below the grabbing station 120. It is also used to pass over the trench and release the grass blocks when the trenching device 200 is trenching. The mechanical claw structure 420 can be a fully automatically controlled mechanical claw structure 420, a clamping structure composed of cooperating mechanical parts, or other structures capable of achieving the above functions.

[0047] When the windbreak and sand-fixing grass block laying device 10 is located on a horizontal surface, the lifting assembly 410 drives the mechanical claw structure 420 to rise and fall in a vertical plane. The lifting assembly 410 can be a connecting rod mechanism, a scissor-type lifting mechanism, a driving cylinder, a lifting mechanism, or other structures, as long as it can drive the mechanical claw structure 420 to rise and fall in a vertical plane.

[0048] For ease of understanding, the working process of the windbreak and sand-fixing grass block paving device 10 is briefly described below:

[0049] (1) starting the windbreak and sand-fixing grass block laying device 10 so that the vehicle body 100 drives the entire windbreak and sand-fixing grass block laying device 10 to move along a preset route;

[0050] (2) During the movement of the windbreak and sand-fixing grass block laying device 10, the trenching device 200 digs the sand on the ground to the left and right sides to form a trench on the ground below;

[0051] (3) While executing the above steps (1) and (2), the conveying device 300 sequentially transfers the grass blocks from the loading station 110 to the grabbing station 120;

[0052] (4) The lifting assembly 410 drives the mechanical claw structure 420 to rise and fall in a vertical plane. When the mechanical claw structure 420 passes below the gripping station 120, it can accurately catch and hold the grass cubes that fall from the gripping station 120. When the mechanical claw structure 420 descends to the top of the trench just opened by the trenching device 200, the mechanical claw structure 420 releases and accurately drops the grass cubes into the trench.

[0053] (5) The sand on both sides of the trench is loosened by the action of the trenching device 200 and flows back into the trench, thereby fixing the grass blocks in the trench and improving the stability of the grass blocks after laying.

[0054] Thus, through the conveying device 300, the lifting assembly 410 and the mechanical claw structure 420, the grass blocks of the loading station 110 can be moved to the top of the newly opened groove for precise placement, thereby reducing the placement height of the grass blocks, and further reducing the probability of the placement position deviating from the groove due to the very lightness of the programmed grass blocks, which is conducive to the quantitative and uniform laying of grass blocks, improves the laying effect of the grass blocks, and enables the grass blocks to better play their role in preventing wind and sand.

[0055] In addition, the conveying device 300 can also accurately and sequentially deliver the grass blocks from the loading station 110 into the mechanical claw structure 420, improving the reliability of the grass block placement process. Moreover, when the mechanical claw structure 420 simultaneously places the grass blocks into the trench while the trenching device 200 digs the trench, some of the sand on both sides of the trench flows back into the trench due to the action of the trenching device 200 and the gravity of the grass blocks, thereby fixing the grass blocks in the trench. This improves the firmness of the laid grass blocks and further enhances the laying effect of the grass blocks.

[0056] Please also refer to Figure 2 In some embodiments, the lifting assembly 410 includes a first rotating shaft 411, a planetary mechanism 412, and a first driving member 413. The first rotating shaft 411 is rotatably mounted on the vehicle body 100 and extends along the second direction 30. Thus, the first rotating shaft 411 is horizontally arranged along the left-right direction.

[0057] Planetary mechanism 412 includes a sun gear 4121, an inner ring gear 4122, planetary gears 4123, and a planetary carrier 4124. Sun gear 4121 is mounted on and in driving connection with first rotating shaft 411. Planetary carrier 4124 is loosely mounted on first rotating shaft 411 and is rotationally connected to the axis of planetary gears 4123. Inner ring gear 4122 is fixed to vehicle body 100.

[0058] The mechanical claw structure 420 is fixed to the side of the planetary carrier 4124 facing away from the planetary gears 4123. The end of the mechanical claw structure 420 facing away from the first rotating shaft 411 has two clamping jaws. These two clamping jaws can be tightened or opened to tighten or loosen the grass blocks. The first driving member 413 is in driving connection with the first rotating shaft 411 and is used to drive the first rotating shaft 411 to rotate, thereby driving the mechanical claw structure 420 to rotate about the first rotating shaft 411.

[0059] It should be noted that a loose sleeve refers to a component being sleeved within another component with a clearance fit, without a fixed connection between the two components. Therefore, there is no direct functional relationship between the components. Therefore, there is no direct functional relationship between the planet carrier 4124 and the first rotating shaft 411.

[0060] In actual use, the first driving member 413 drives the first rotating shaft 411 to rotate, thereby driving the planetary gear 4123 to rotate along the circumference of the inner ring gear 4122, thereby driving the mechanical claw structure 420 to rotate around the first rotating shaft 411, realizing the lifting and lowering of the mechanical claw structure 420.

[0061] Since the planetary mechanism 412 is a gear transmission structure, it has the advantages of high transmission accuracy and efficiency, long service life, smooth operation and high reliability. Therefore, the lifting component 410 is set to the first rotating shaft 411, the planetary mechanism 412 and the first driving member 413, which can improve the operation accuracy and working stability of the lifting component 410, and extend the service life of the lifting component 410, so as to further improve the laying effect and use reliability of the above-mentioned windbreak and sand-fixing grass block laying equipment 10.

[0062] Furthermore, in some embodiments, the delivery device 400 also includes a cam 430. The cam 430 is loosely mounted on the first rotating shaft 411 and is fixedly connected to the vehicle body 100. The mechanical claw structure 420 includes a fixed seat fixed to the planetary frame 4124, a grabbing rod, a gripping seat, and two claw structures arranged opposite to each other. One end of each claw structure is rotatably connected to the gripping seat. The grabbing rod is slidably mounted on the fixed seat along the axial direction of the first rotating shaft 411. One end of the grabbing rod is slidably abutted against the outer peripheral edge of the cam 430 along the circumference of the cam 430, and the other end is slidably mounted on the gripping seat, and is respectively linked to the two claw structures. Therefore, when the first rotating shaft 411 drives the sun gear 4121 to rotate, the cam 430 is always in a stationary state. At this time, the fixed seat fixed on the planetary carrier 4124 will drive the grabbing rod and the claw structure to rotate around the first rotating shaft 411 and slide on the outer periphery of the cam to drive the grabbing rod to slide along the circumference of the first rotating shaft 411, thereby driving the two claw structures to rotate relative to each other to clamp or separate each other, so as to clamp the grass block when it falls from the grabbing station 120 and release the grass block when it passes through the groove.

[0063] Please also refer to Figure 3Furthermore, in one embodiment of the present invention, the outer periphery of the cam 430 includes a first arc segment 431, a first arc segment 432, a second arc segment 433, a second arc segment 434, and a third arc segment 435, which are sequentially connected and smoothly transitioned along the circumference of the first rotating shaft 411. Both the first arc segment 431 and the second arc segment 434 extend circumferentially along the inner hole of the cam 430, with the diameter of the first arc segment 431 being larger than the diameter of the second arc segment 434. The circumferential dimension of the first arc segment 432 along the inner hole of the cam 430 is smaller than the radial dimension of the first arc segment 432 along the inner hole of the cam 430. The first arc segment 432 is located directly below and facing the gripping station 120. The third arc segment 435 is located above the trenching device and faces rearward in the direction of vehicle travel. When the gripping rod slidably contacts the first arc segment 431, the two claw structures are in an open state. When the grabbing rod is in slidable contact with the second arc segment 434 , the two claw structures are in a clamping state.

[0064] Thus, when the grabbing rod slides from the first arc segment 431 to the second arc segment 432, the two claw structures in the open state catch the grass block dropped from the grabbing station 120 and are quickly tightened until the distance between the two claw structures is less than the thickness of the grass block, so as to quickly clamp the grass block; when the grabbing rod slides from the first arc segment 432 to the second arc segment 433, the two claw structures are slightly opened outward, so that the distance between the two claw structures is slightly smaller than the thickness of the grass block. The thickness of the grass block can be adjusted to just clamp the grass block without pinching the grass block; when the grabbing rod slides from the second arc section 433 through the second arc section 434 to the third arc section 435, the two claw structures clamp the grass block and drive the grass block to move to the rear of the vehicle's travel direction and above the opened groove; when the grabbing rod slides from the second arc section 434 through the third arc section 435 to the first arc section 431, the two claw structures open outward to loosen the grass block and allow the grass block to fall into the opened groove.

[0065] Please also refer to Figure 4 Furthermore, in another embodiment of the present invention, the outer periphery of the cam 430 includes a third arc segment 436, a fourth arc segment 437, a fourth arc segment 438, and a fifth arc segment 439, which are sequentially connected and smoothly transitioned along the circumference of the first rotating shaft 411. The third arc segment 436 and the fourth arc segment 438 both extend along the circumference of the inner hole of the cam 430, and the diameter of the third arc segment 436 is larger than the diameter of the fourth arc segment 438. The fourth arc segment 437 is located directly below the grabbing station 120 and is disposed toward the grabbing station 120. When the grabbing rod slidably contacts the third arc segment 436, the two claw structures are in an open state. When the grabbing rod contacts the fourth arc segment 438, the two claw structures are in a clamped state.

[0066] In this way, when the grabbing rod slides from the third arc segment 436 to the fourth arc segment 437 to the fourth arc segment 438, the two claw structures in the open state catch the grass block dropped from the grabbing station 120 and quickly retract inward to quickly clamp the grass block; when the grabbing rod slides from the fourth arc segment 437 to the fifth arc segment 438 to the fifth arc segment 439, the two claw structures clamp the grass block and drive the grass block to the rear of the vehicle's travel direction until the grass block reaches above the opened groove; when the grabbing rod slides from the fourth arc segment 438 to the fifth arc segment 439 to the third arc segment 436, the two claw structures open outward to release the grass block and allow the grass block to fall into the opened groove.

[0067] The meanings of some terms in the above-mentioned embodiments are explained. The inner hole of the cam 430 refers to the hole on the cam 430 used to be sleeved on the first rotating shaft 411, and the inner wall of the hole can be in contact with the first rotating shaft 411; the meaning of "empty sleeve" in the above-mentioned embodiments is the same as the meaning of "empty sleeve" between the planetary carrier 4124 and the first rotating shaft 411, so there is no direct functional relationship between the cam 430 and the first rotating shaft 411.

[0068] Please refer again Figure 1 and Figure 2 Furthermore, in some embodiments, the trenching device 200 includes a second rotating shaft 210, a trenching assembly 220, and a first transmission member 230. The second rotating shaft 210 is rotatably mounted on the vehicle body 100 and is parallel to and spaced from the first rotating shaft 411.

[0069] Please also refer to Figure 5 The furrowing assembly 220 includes a sleeve 221 that is sleeved and fixed on the second rotating shaft 210 and a plurality of furrowing rods 222 that are spaced apart along the circumference of the sleeve 221. A furrowing plow 223 is provided at one end of each furrowing rod 222 away from the sleeve 221.

[0070] The second rotating shaft 210 is connected to the first rotating shaft 411 through the first transmission member 230. The first driving member 413 is used to drive the first rotating shaft 411 to rotate, thereby driving the furrowing plow 223 to rotate about the second rotating shaft 210 to dig the ground sand to both sides to form a furrow. The first transmission member 230 can be a belt transmission structure, a chain transmission structure, or a gear transmission structure. The configuration of the first transmission member 230 allows the first driving member 413 to simultaneously drive the first rotating shaft 411 and the second rotating shaft 210 to rotate, ensuring that the furrowing work and the placement of the grass blocks are carried out simultaneously, thereby further improving the accuracy of the grass block placement.

[0071] Furthermore, the rotation of the second rotating shaft 210 drives the multiple furrowing plows 223 to rotate about the second rotating shaft 210, thereby achieving continuous sand-digging and furrowing operations on the ground. This not only simplifies and facilitates the furrowing operation but also improves the furrowing efficiency. Furthermore, when the furrowing plows 223 are used to dig sand from the ground, the sand can be digged to the left and right sides of the furrowing plows 223, thereby digging the sand to both sides of the furrow. This facilitates the subsequent return of the sand to fix the grass blocks.

[0072] Furthermore, in some embodiments, there are multiple furrowing assemblies 220. The multiple furrowing assemblies 220 are spaced apart along the second direction 30. In the second direction 30, any two adjacent furrowing rods 222 are staggered. Thus, in the second direction 30, any two adjacent furrowing plows 223 are staggered. Specifically, in this embodiment, the furrowing device 200 includes two furrowing assemblies 220. Since the multiple furrowing assemblies 220 are spaced apart along the second direction 30, providing multiple furrowing assemblies 220 allows the furrowing device 200 to form wider trenches on the ground, which is beneficial for improving the efficiency of laying grass blocks. Furthermore, in the second direction 30, any two adjacent furrowing plows 223 are staggered. In this case, the two adjacent furrowing plows 223 can cooperate with each other, with one plowing away the sand on the ground while the other plowing away the sand on both sides of the trench to bury and secure the grass blocks within the trench. This further improves the convenience of laying the grass blocks and the firmness of the laid grass blocks.

[0073] Please refer again Figure 1 Furthermore, in some embodiments, the vehicle body 100 includes two support structures 130, a support ring 140, a connector 150, and two sets of running mechanisms 160 respectively disposed at the bottom of the two support structures 130. Specifically, each set of running mechanisms 160 includes at least two running wheels 161 spaced apart along the first direction 20.

[0074] The two support structures 130 and the support ring 140 are spaced apart along the second direction 30. The support ring 140 is located between the two support structures 130. The connecting member 150 is fixedly connected to the two support structures 130 and the support ring 140 respectively.

[0075] A support plate 170 is fixed to the connecting member 150. The support plate 170 is located between the support ring 140 and the support structure 130. The support plate 170 and the support structure 130 are respectively provided with a first mounting hole (not shown) and a second mounting hole (not shown). A second rotating shaft 210 is rotatably inserted into the first mounting hole. One end of the second rotating shaft 210 is rotatably inserted into the second mounting hole, and the other end is suspended between the inner ring gear 4122 and the support plate 170. The trenching assembly 220 is located between the inner ring gear 4122 and the support plate 170. The first transmission member 230 is disposed between the support plate 170 and the support structure 130.

[0076] Thus, the support plate 170 and the support structure 130 form two support points on the second rotating shaft 210, thereby improving the structural stability of the trenching device 200. Furthermore, the trenching assembly 220 and the first transmission member 230, both serving as force-bearing structures, are disposed on either side of the support plate 170, further improving the structural and operational stability of the trenching device 200.

[0077] Furthermore, in some embodiments, there are two planetary carriers 4124. The two planetary carriers 4124 are fixedly connected to the axis positions at both ends of the planetary gear 4123. Each planetary carrier 4124 is provided with a mechanical claw structure 420 at one end away from the planetary gear 4123.

[0078] There are two loading stations 110 and two grabbing stations 120. The two grabbing stations 120 are respectively located at both ends of the inner gear ring 4122 and are arranged between the two loading stations 110.

[0079] There are two conveying devices 300 and two trenching devices 200. The two conveying devices 300 are spaced apart at both ends of the inner gear ring 4122 along the second direction 30. The two trenching devices 200 are spaced apart at both ends of the inner gear ring 4122 along the second direction 30. The two second rotating shafts 210 are coaxially arranged.

[0080] Therefore, in actual use, two trenches can be dug at the same time, and two groups of grass blocks can be laid at the same time using two conveying devices 300 and two placing devices 400, which is beneficial to improving the efficiency of grass block laying.

[0081] Please also refer to Figure 6 In some embodiments, the conveying device 300 includes a plurality of spaced-apart pushing portions 310 . The plurality of pushing portions 310 are arranged in a linear array along the second direction 30 . Each pushing portion 310 is operable to move along the second direction 30 to push a grass block from the loading station 110 to the grabbing station 120 . Thus, the arrangement of the plurality of pushing portions 310 arranged in a queue can simultaneously push multiple grass blocks in a queue along the second direction 30 , thereby improving the conveying efficiency of the grass blocks and, in turn, improving the laying efficiency of the grass blocks.

[0082] Furthermore, in some embodiments, the conveying device 300 includes a conveyor frame 320, a material-discharging bar 330, and a second driving member (not shown). The conveyor frame 320 is fixed to the vehicle body 100 along the second direction 30. The conveyor frame 320 is formed with an elongated through-slot 321 along the second direction 30. The material-discharging bar 330 is movably mounted on the side of the conveyor frame 320 facing the furrowing device 200. A plurality of material-discharging claws 331 are spaced apart along the second direction 30 on the side of the material-discharging bar 330 facing the conveyor frame 320. A pushing portion 310 is formed between two adjacent material-discharging claws 331. The second driving member is transmission-connected to the material-discharging bar 330 and is configured to drive the material-discharging bar 330 to move along the length and depth of the elongated through-slot 321, respectively, so that the material-discharging claws 331 pass through the elongated through-slot 321 and move the grass blocks on the conveyor frame 320 from the loading station 110 to the grabbing station 120.

[0083] There may be one or more elongated through-slots 321. When there are multiple elongated through-slots 321, the plurality of elongated through-slots 321 are spaced apart along the second direction 30. When the windbreak and sand-fixing grass block laying device 10 is located on a horizontal plane, the length direction of the elongated through-slots 321 is a horizontal direction consistent with the second direction 30, and the depth direction of the elongated through-slots 321 is a vertical direction perpendicular to the second direction 30.

[0084] Therefore, when it is necessary to transfer the grass blocks from the loading station 110 to the grabbing station 120, the second driving member drives the second rotating shaft 210 to rotate. During the rotation of the second rotating shaft 210, the material stripping bar 330 is first driven to move upward until the pushing portion 310 is located above the conveying rack 320; then the material stripping bar 330 is driven to move along the second direction 30, so as to use the material stripping portion to shift the grass blocks on the conveying rack 320 toward the grabbing station 120; then the material stripping bar 330 is driven to move downward until the pushing portion 310 is located below the conveying rack 320; then the material stripping bar 330 is driven to move in the direction toward the loading station 110 to achieve reset; repeat the above steps, and under the action of multiple pushing portions 310 arranged in a queue, the queue movement of multiple grass blocks can be achieved.

[0085] Furthermore, in some embodiments, the conveying device 300 further includes two material stops 350. The two material stops 350 are fixed to the loading station 110 at intervals along the first direction 20 and are located on either side of the conveying frame 320. Thus, the two material stops 350 are primarily used to protect the grass blocks at the loading station 110, preventing the grass blocks at the loading station 110 from sliding off the front and rear sides of the conveying frame 320 during operation of the windbreak and sand-fixing grass block laying device 10, thereby further improving the reliability of the windbreak and sand-fixing grass block laying device 10.

[0086] Furthermore, in some embodiments, the conveying device 300 further includes a stopper 360. The stopper 360 is disposed at an end of the conveying frame 320 away from the gripping station 120 and is fixedly connected to the vehicle body 100. The stopper 360 is used to limit the loading position of the grass blocks on the conveying frame 320 in the second direction 30.

[0087] Therefore, the setting of the limiter 360 can not only prevent the probability of the grass blocks at the loading station 110 from sliding off the conveying rack 320 from one end of the grabbing station 120, thereby further improving the reliability of the wind-proof and sand-fixing grass block paving equipment 10, but also accurately limit the loading position of the grass blocks on the conveying rack 320, thereby reducing the probability that the conveying device 300 cannot align with the grass blocks at the loading station 110 during the process of transferring the grass blocks from the loading station 110 to the grabbing station 120, thereby further improving the conveying reliability of the conveying device 300, thereby making the above-mentioned wind-proof and sand-fixing grass block paving equipment 10 more reliable in use.

[0088] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
