In the traditional technology, artificial methods are usually used to lay sand barriers, such as manually making grass square sand barriers or manually planting sand willow branch sand barriers. Although these methods have played a certain role in sand prevention and control, they have the problems of high labor intensity, low construction efficiency and difficult uniformity of laying quality, which are difficult to meet the needs of large-scale desert control and construction of photovoltaic power stations in desert areas.

Although this sand barrier laying device can complete the automatic sand barrier laying work, the height of the laid sand barrier materials is not uniform, which cannot meet the higher standard sand barrier laying requirements, and the windproof ability of the sand barrier is poor. SUMMARY

[0004] Therefore, the present application provides a sand barrier automatic laying device and a sand barrier automatic laying method to solve the problems of non-uniform height of laid sand barrier materials and poor windproof ability.

[0033] Advantages

[0034] The laser line marker can guide the vehicle body to travel along the preset path accurately, ensuring that the trenching mechanism always trenches along the center axis of the vehicle body, preventing the vehicle body from deviating from the path and causing the sand barrier to be laid obliquely or deviated.

[0053] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0054] The embodiments of the present application will be described below in combination with Figs. 1 to 3 .

[0055] According to the embodiment of the present application, in one aspect, a sand barrier automatic laying device is provided, comprising a vehicle body 1, a trenching mechanism 2, a sand barrier grafting mechanism, a sand barrier height adjusting mechanism and a soil covering mechanism. The upper end of the trenching mechanism 2 is connected with the vehicle body 1, and the lower end is inserted into the sandy soil. The trenching mechanism 2 is suitable for digging a trench along the central axis of the vehicle body 1 as the vehicle body 1 travels. The sand barrier grafting mechanism is arranged on the vehicle body 1 and located behind the trenching mechanism 2 in the traveling direction of the vehicle body 1. The sand barrier grafting mechanism comprises a sand barrier hopper 31 and a grafting device 32. The sand barrier material 33 is placed in the sand barrier hopper 31. The grafting device 32 is arranged at the discharge port of the sand barrier hopper 31 and is suitable for grafting the sand barrier material 33 in the sand barrier hopper 31 into the trench. The sand barrier height adjusting mechanism is arranged on the vehicle body 1 and located behind the sand barrier grafting mechanism in the traveling direction of the vehicle body 1. The sand barrier height adjusting mechanism is suitable for adjusting the height of the sand barrier material 33 inserted into the trench. The soil covering mechanism is connected with the vehicle body 1 and located behind the sand barrier height adjusting mechanism in the traveling direction of the vehicle body 1. The soil covering mechanism is suitable for backfilling the sandy soil dug when the trench is dug into the trench to fix the sand barrier material 33 inserted into the trench.

[0056] Specifically, the vehicle body 1 is the main structure of the sand barrier automatic laying device, which can move at a uniform speed or variable speed along the preset laying route. The vehicle body 1 can be a tracked vehicle body 1 or a wheeled vehicle body 1, which is suitable for soft terrain such as sandy land and has good mobility and carrying capacity, and can stably advance in the sandy terrain.

[0057] The trenching mechanism 2 is arranged at the front end of the vehicle body 1 and on the central axis of the vehicle body 1. The upper end of the trenching mechanism 2 is fixedly connected with the bottom of the vehicle body 1, and the lower end is sharp and can be inserted into the sandy land surface. It can dig a trench during the travel of the vehicle body 1, providing a grafting path for subsequent insertion of the sand barrier material 33.

[0058] Optionally, the trenching mechanism 2 can be a fixed length structure, which is fixed to the bottom of the vehicle body 1 by screwing, and can be suitable for sand barrier laying operation of conventional depth; or it can be an adjustable length structure, which is driven to rise and fall by an electric screw or a hydraulic cylinder, so as to control the depth of the trenching mechanism 2 inserted into the ground, thereby digging trenches of different depths.

[0059] The sand barrier grafting mechanism is installed in the middle of the vehicle body 1. The sand barrier hopper 31 is in a cylindrical structure, and its discharge port is located at the center line position of the vehicle body 1. The sand barrier material 33 is vertically inserted into the sand barrier hopper 31 and vertically inserted into the dug trench under the driving of the grafting device 32.

[0060] Optionally, the sand barrier material 33 selects vertical rod-shaped materials such as sand willow branches and straw bundles.

[0061] The sand barrier height adjusting mechanism is arranged along the center line of the vehicle body 1. Due to the different heights of the sand barrier materials 33 inserted into the groove, the sand barrier height adjusting mechanism can uniformly adjust the height of the sand barrier materials 33, ensuring the consistency of the subsequent sand barriers in height and improving the windproof effect.

[0062] The covering mechanism is arranged behind the sand barrier height adjusting mechanism. During the movement of the vehicle body 1, the covering mechanism pushes the sand soil turned over by the trenching mechanism 2 back into the groove, and compacts the loose sand soil in the groove, ensuring the stability of the sand barrier.

[0063] In an embodiment, the trenching mechanism 2 comprises a trenching shovel, which is in a V-shaped structure.

[0064] Specifically, the trenching shovel is integrally formed by bending and welding a high-strength alloy steel plate. The upper end of the trenching shovel is fixed to the bottom of the front end of the vehicle body 1 by screwing, and the lower end is inserted into the sand soil surface with the tip downward. The included angle between the two side wings of the V-shaped structure is preferably 60°, which balances the sand soil cutting resistance and the groove forming quality.

[0065] During the movement of the vehicle body 1, the V-shaped trenching shovel continuously advances along the vehicle center axis direction, and the two inclined side wings can effectively separate and push the sand soil to both sides of the groove, which is beneficial to the stable insertion of the subsequent sand barrier materials 33. At the same time, the bottom front edge of the V-shaped trenching shovel is provided with a soil guide knife edge, which can further reduce the forward resistance and enhance the trenching stability.

[0066] In an embodiment, the sand barrier hopper 31 is provided with a rotating feeder 34, which is rotationally connected with the sand barrier hopper 31.

[0067] Specifically, the rotating feeder 34 is composed of an arc-shaped blade, a rotating shaft and a driving motor. One end of the rotating feeder 34 is rotationally connected with the center position of the sand barrier hopper 31, and the driving end of the driving motor is connected with the rotating shaft to drive the rotating feeder 34 to rotate.

[0068] When the sand barrier materials 33 are put into the sand barrier hopper 31, the rotating feeder 34 rotates under the driving of the motor, and the arc-shaped blade rotates to push the sand barrier materials 33, which are gradually pushed to the discharge port of the sand barrier hopper 31, and then inserted into the groove through the inserting device 32.

[0069] Optionally, the rotating speed of the rotating feeder 34 can be adjusted by controlling the rotating speed of the driving motor, so as to adapt to different types of sand barrier materials 33 and the density requirements of the sand barrier.

[0070] In one embodiment, the cutting device 32 comprises a positioning guide plate 321 and a sand barrier cloth crawler device 322, the positioning guide plate 321 is connected with one side of the outer wall of the discharge port of the sand barrier hopper 31, and the sand barrier cloth crawler device 322 is connected with the other side of the discharge port of the sand barrier hopper 31. The sand barrier cloth crawler device 322 comprises two crawler wheels and a cloth crawler, the two crawler wheels are arranged in a vertical direction, and the cloth crawler is arranged around the two crawler wheels. The feeding device 34 pushes the sand barrier material 33 onto the cloth crawler, and the cloth crawler drives the sand barrier material 33 to be vertically inserted into the trench along the positioning guide plate 321.

[0071] Specifically, the positioning guide plate 321 is connected with the outer wall of one side of the discharge port of the sand barrier hopper 31, and the positioning guide plate 321 is a rigid flat plate with a guide surface. The plate surface is vertical and parallel to the center line of the vehicle body 1, which can prevent the sand barrier material 33 from tilting or shifting when guiding the sand barrier material 33 to be inserted, and ensures that the sand barrier material 33 is inserted into the ground in a vertical direction.

[0072] The sand barrier cloth crawler device 322 is arranged on the other side of the center line of the vehicle body 1 and connected with the other side of the discharge port of the sand barrier hopper 31. The two crawler wheels are arranged on the upper and lower shafts, respectively. The lower crawler wheel is a driving wheel connected with the driving motor, and the upper crawler wheel is a driven wheel for tensioning and guiding the cloth crawler. The cloth crawler is arranged around the two crawler wheels, and the width direction of the cloth crawler is parallel to the center line of the vehicle body 1, forming an insertion path along the center line of the vehicle body 1 with the positioning guide plate 321.

[0073] When the sand barrier cloth crawler device 322 works, the feeding device 34 pushes the sand barrier material 33 out of the discharge port of the sand barrier hopper 31, the sand barrier material 33 contacts with the cloth crawler, the driving motor drives the crawler wheels to rotate and drives the cloth crawler to rotate, the cloth crawler in the rotating state gives the sand barrier material 33 a vertical downward frictional force, and the sand barrier material 33 keeps a vertical downward posture and is inserted into the trench under the vertical guidance of the positioning guide plate 321, thereby completing the cutting work of the sand barrier material 33.

[0074] Optionally, the cloth crawler is made of high-strength flexible rubber material, and the surface has anti-skid convex points to enhance the frictional traction force on the sand barrier material 33.

[0075] In one embodiment, the sand barrier height adjusting mechanism comprises a lifting support 41 and a rotating roller 42, the lifting support 41 is connected with the tail of the vehicle body 1, and the rotating roller 42 is rotatably arranged on the lifting support 41.

[0076] Specifically, the lifting support 41 is installed on the crossbeam at the tail of the vehicle body 1, the top of the lifting support 41 is rigidly connected with the vehicle body 1, and the bottom is connected with a rotating support shaft, the length direction of the rotating support shaft is perpendicular to the center line direction of the vehicle body 1, and the rotating roller 42 is arranged on the rotating support shaft and rotationally connected with the rotating support shaft. The electric push rod or hydraulic cylinder is arranged on the lifting support 41, so that the rotating support shaft moves up and down in the vertical direction, and the height of the rotating roller 42 is adjusted.

[0077] After the sand barrier material 33 is inserted into the trench by the cutting device 32, the vehicle body 1 continues to advance, the rotating roller 42 is pressed above the sand barrier material 33 inserted into the trench, the sand barrier material 33 is pressed to a set height, and the insertion angle and position of the sand barrier material 33 are ensured to be vertical and central. The lifting support 41 can adjust the position of the rotating roller 42 according to the length of different sand barrier materials 33 or the wind area requirement, so that the insertion height of the sand barrier material 33 is consistent.

[0078] The rotating roller 42 is a horizontally arranged cylindrical roller shaft, both ends of the roller shaft are installed on the rotating support shaft through bearings, and the surface of the roller shaft is covered with rubber to increase the friction between the roller shaft and the sand barrier material 33.

[0079] Optionally, the rotating roller 42 can rotate freely during the advance of the vehicle body 1, or be driven to rotate by a motor when needed, so as to adapt to different laying requirements.

[0080] In an embodiment, the soil covering mechanism includes a backfill assembly 51 and a flattening assembly 52, and the flattening assembly 52 is arranged behind the backfill assembly 51 in the advance direction of the vehicle body 1.

[0081] Specifically, the backfill assembly 51 is installed on the backfill support at the rear of the vehicle body 1 and can push the sand excavated by the trenching shovel on both sides of the trench back into the trench. The flattening assembly 52 is arranged behind the backfill assembly 51 and is used to compact the backfilled sand and flatten the ground surface, so as to further improve the fixing effect of the sand barrier material 33.

[0082] In an embodiment, the backfill assembly 51 includes two backfill wheels 511, the two backfill wheels 511 are symmetrically arranged on both sides of the trench, and the distance between the two backfill wheels 511 gradually decreases from the end close to the vehicle body 1 to the end away from the vehicle body 1.

[0083] The backfill wheel 511 is a disc-shaped structure and is installed on the backfill support through a rotating shaft, one end of the support is fixed at the rear of the vehicle body 1, and the other end is suspended above both sides of the trench. The two backfill wheels 511 are obliquely installed on the backfill support and form a gradually narrowing V-shaped channel in the advance direction of the vehicle body 1.

[0084] When the vehicle body 1 moves in the advancing direction, the sand on both sides of the trench is first guided to converge by the wider end of the backfilling wheel 511, and then is concentrated and pushed to the center of the trench in a gradually decreasing wheel track, thereby achieving effective backfilling of the sand. At the same time, the gravity and rolling action of the wheel body of the backfilling wheel 511 can preliminarily compact the sand, thereby improving the stability of the sand barrier material 33.

[0085] Optionally, the backfilling wheel 511 can be made of solid rubber material, and the rim surface is provided with radial ridges to enhance the gripping force and pushing capacity in the sand.

[0086] In one embodiment, the leveling assembly 52 includes two leveling rollers 521 which are symmetrically arranged on both sides of the trench, and the rotation shafts of the leveling rollers 521 are perpendicular to the length direction of the trench.

[0087] Specifically, the leveling roller 521 is a hollow steel cylinder, and the outer surface is covered with an elastic rubber layer, which has good buffering and compacting effect. The two leveling rollers 521 are respectively rotatably installed on the support arms at the rear end of the vehicle body 1, and the support arms are transversely adjustably connected to the tail part of the vehicle body 1, so that the transverse position of the leveling rollers 521 can be flexibly adjusted according to the width of the trench to adapt to different trench widths.

[0088] The two leveling rollers 521 are symmetrically arranged on both sides of the trench, and the rotation shafts of the two leveling rollers 521 are perpendicular to the length direction of the trench, for compacting and leveling the backfilled sand surface. During the movement of the vehicle body 1, after the sand is backfilled and preliminarily compacted by the backfilling assembly 51, the two leveling rollers 521 are respectively rolled on the backfilled sand surface under the driving of the vehicle body 1. Since the roller body has a certain weight and forms a line contact with the sand surface, the surface sand can be further compacted, so that the sand surface is smooth and compact, and the wind resistance and stability of the sand barrier root structure are enhanced.

[0089] Optionally, in order to adapt to different terrains or compacting requirements, the leveling roller 521 can also be provided with a pneumatic spring or an adjustable ballast device to realize dynamic adjustment of the pressing force. If the ground is uneven or the sand is soft, the two roller bodies can automatically adapt to different height differences to avoid uneven compaction.

[0090] In one embodiment, the sand barrier automatic laying device further includes a laser line marker 6 which is arranged at the front end of the vehicle body 1 and located on the center axis of the vehicle body 1.

[0091] The laser line marker 6 is fixedly installed at the front head position of the vehicle body 1, the light outlet thereof is consistent with the center axis direction of the vehicle body 1, and the laser line is projected on the sand surface in front.

[0092] Specifically, the laser wire marker 6 adopts an industrial laser emission module, and the emission wavelength is in the visible red light range (e.g., 650 nm), and the beam intensity is moderate, which is suitable for visual operation requirements under outdoor strong light conditions. The laser shell is a sealed dustproof structure, which has the functions of wind and sand resistance and shock resistance, and is suitable for complex environments in desert areas.

[0093] Optionally, to adapt to the undulating terrain, the laser can be equipped with an electric fine adjustment function to adjust the pitch angle, so that the projected line always remains flat on the ground.

[0094] According to an embodiment of the present application, in another aspect, a sand barrier automatic laying method applied to a sand barrier automatic laying device is also provided, which comprises the following steps:

[0095] The trenching mechanism 2 excavates a trench along the center axis of the vehicle body 1 as the vehicle body 1 travels on the sandy land surface;

[0096] Before the laying work starts, the sand barrier material 33 is filled into the sand barrier hopper 31. Then the vehicle body 1 is started at the starting point of the work area. The vehicle body 1 travels along the transmission line of the laser wire marker 6. During the travel of the vehicle body 1, the trenching shovel of the trenching mechanism 2 is inserted into the sandy soil to continuously excavate a trench along the center axis of the vehicle body 1, forming a regular sand barrier implantation channel.

[0097] The sand barrier material 33 in the sand barrier hopper 31 is inserted into the trench by the cutting device 32;

[0098] Subsequently, the sand barrier material 33 in the sand barrier hopper 31 is slowly pushed to the discharge port under the action of the rotating feeder 34, and is pushed by the cutting device 32 and guided by the positioning guide plate 321, so as to be vertically inserted into the trench, thereby forming continuous and uniform sand barriers.

[0099] The sand barrier height adjusting mechanism adjusts the height of the sand barrier material 33 inserted into the trench;

[0100] After the insertion is completed, the rotating roller 42 compacts and corrects the height of the sand barrier material 33 inserted into the trench, so as to ensure that the height of each sand barrier material 33 exposed on the ground is consistent, and the overall windproof effect and insertion neatness of the sand barrier material 33 are improved.

[0101] The soil covering mechanism backfills the sandy soil on both sides of the trench into the trench, and compacts the backfilled sandy soil to fix the sand barrier material 33 inserted into the trench.

[0102] Finally, the two backfilling wheels 511 of the backfilling assembly 51 push the sandy soil excavated during the trenching process into the trench, and preliminarily compact the sandy soil. The flattening roller 521 of the flattening assembly 52 rolls and compacts the soft sandy soil on both sides of the sand barrier material 33, so as to ensure that the sand barrier structure is stable and the appearance is regular.

[0103] While embodiments of the application have been described in connection with the preferred embodiments of the various figures, those of ordinary skill in the art will appreciate that various modifications and variations of the preferred embodiments can be employed without departing from the spirit and scope of the application.
