DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] The present invention provides a mixed seeding device for restoration of degraded vegetation in sandy land, such as Figures 1 to 4 As shown, it includes two relative mobile brackets 1, which are moved on the ground by wheels, a spraying component is placed on the top of the mobile bracket 1, and the spraying component is supported by a supporting component on the top of the mobile bracket 1; the spraying component includes a water tank 2, a hose 3 and a spray head 4; the top end of the hose 3 is connected to the water tank 2, and the bottom end of the hose 3 is connected to the spray head 4. The supporting component includes two relative rotating plates 5, an arc frame 6 and a fastening component; the bottom end of the rotating plate 5 is connected to the top of the mobile bracket 1 by a connecting component, and the bottom end of the rotating plate 5 moves on the top of the mobile bracket 1 by a connecting component, both ends of the arc frame 6 are provided with side edges, and the top end of the rotating plate 5 is hinged to the side edges, and the fastening component limits the end of the water tank 2 to the top of the arc frame 6, and a plurality of hoses 3 are sleeved with a dial plate 7, and both ends of the dial plate 7 are fixed with a deflection plate 8, and the dial plate 7 and the two deflection plates 8 form an I-shaped plate, and the end of the deflection plate 8 is installed in the middle of the rotating plate 5 by a limiting component. When the mobile bracket 1 moves on the sand using the wheels, the moving mobile bracket 1 enables the hose 3 to drive the spray head 4 to move synchronously through the rotating plate 5 and the I-plate, thereby preventing the hose 3 from causing the spray head 4 to swing at the bottom of the water tank 2, and preventing the swinging spray head 4 from causing the seeding liquid to be sprayed indiscriminately, thereby failing to ensure the uniformity of the seeding liquid spraying.

[0031] When the limiting component limits one end of the deflection plate 8, the connecting component causes the bottom end of the rotating plate 5 to move. Since the top end of the rotating plate 5 is hinged to the side of the arc frame 6, when the bottom ends of the two rotating plates 5 move away from each other, the top end of the rotating plate 5 causes the arc frame 6 to move downward, and the rotating plate 5 uses the limiting component to move the end of the deflection plate 8 downward, and the other end of the deflection plate 8 moves up on the surface of the other rotating plate 5. At this time, the I-shaped hose 3 is used to drive the spray head 4 to deflect, so that the spraying range of the spray head 4 is increased, and the offset spray head 4 can quickly spray the inclined sand surface.

[0032] exist Figures 1 to 4In the embodiment, the fastening components include a first arc plate 9, a second arc plate 10 and a side rod 11; two side rods 11 are installed on the side of the arc frame 6, the first arc plate 9 and the second arc plate 10 are arranged opposite to each other, the bottom ends of the first arc plate 9 and the second arc plate 10 are respectively sleeved on the surface of the side rod 11, the top of the first arc plate 9 is provided with a convex strip, the top of the second arc plate 10 is provided with a groove, the convex strip is correspondingly inserted into the inside of the groove, and the top of the first arc plate 9 and the second arc plate 10 are connected by bolts, the first arc plate 9, the second arc plate 10 and the arc frame 6 cooperate to form a clamping frame, and the clamping frame cooperates to clamp the end of the water tank 2. The water tank 2 is placed inside the groove at the top of the arc frame 6, and the first arc plate 9 and the second arc plate 10 are rotated. The first arc plate 9 and the second arc plate 10 are rotated by using the side rod 11 until the inner concave surface of the first arc plate 9 and the inner concave surface of the second arc plate 10 are both in contact with the outer circumferential surface of the water tank 2. At this time, the convex strip at the top of the first arc plate 9 is inserted into the groove of the second arc plate 10, and the bolts are passed through the top of the first arc plate 9 and the second arc plate 10. The first arc plate 9 and the second arc plate 10 are fixed by the bolts, so that the water tank 2 is clamped by the first arc plate 9 and the second arc plate 10. At this time, the clamping frame completes the fixing of the water tank 2. When the mobile bracket 1 moves on the sand using the wheels, the mobile bracket 1 drives the water tank 2 to move synchronously through the clamping frame.

[0033] exist Figure 1 , Figure 2 and Figure 6 In the embodiment, the connecting parts include a rotating rod 12, a slider 13, a gear 14 and a protruding rod 15; the gears 14 are fixed at both ends of the rotating rod 12, and the rotating rod 12 spirally penetrates the center of the slider 13, the protruding rod 15 is installed on the side of the slider 13, and the bottom end of the rotating plate 5 is sleeved on the surface of the protruding rod 15, the number of sliders 13 is set to two, and the two sliders 13 are both provided with a screw groove corresponding to the rotating rod 12, and the screw groove is provided with an internal thread, and the internal threads of the two sliders 13 are in opposite directions, and the outer side of the gear 14 is transmission-connected to the output end of the motor. The bottom surface of the slider 13 is in contact with the top surface of the mobile bracket 1, and the rotating rotating rod 12 makes the two opposite sliders 13 approach or move away from each other. Start the motor, and the motor output end causes the gear 14 to rotate. Since the inner side surface of the gear 14 fits with the end surface of the mobile bracket 1, the rotating gear 14 causes the rotating rod 12 to rotate on the top of the mobile bracket 1. Since the bottom surface of the slider 13 fits with the top surface of the mobile bracket 1, and the slider 13 is spirally sleeved on the surface of the rotating rod 12 using a screw groove, the rotating rotating rod 12 causes the slider 13 to slide on the mobile bracket 1.

[0034] Since the internal threads of the two sliders 13 have opposite spiral directions, the rotating rotating rod 12 makes the two relative sliders 13 approach or move away from each other. At this time, the moving slider 13 uses the convex rod 15 to drive the bottom end of the rotating plate 5 to move synchronously. Since the top of the rotating plate 5 is hinged to the side of the arc frame 6, the bottom ends of the two rotating plates 5 approaching each other at this time make the arc frame 6 move upward, and the upward arc frame 6 makes the spray head 4 move upward through the water tank 2 and the hose 3, so as to adjust the relative distance between the spray head 4 and the sand in real time to avoid collision with soil and rocks on the sand due to the spray head 4 being too low.

[0035] exist Figure 1 , Figure 2 , Figure 5 and Figure 6 In the embodiment, the limiting components include an inner tube 16, a circular plate 17, a sleeve 18 and an insertion rod 19; the inner tube 16 is fixed with a circular plate 17 at both ends, the sleeve 18 is spirally sleeved on the surface of the circular plate 17, the outer end of the insertion rod 19 is fixed at the center of the sleeve 18, the inner end of the insertion rod 19 is inserted into the inner tube 16 through the circular plate 17, and a plurality of arc-shaped rubber strips 20 are installed on the inner side of the sleeve 18. The spiral cooperation of the rotating sleeve 18 and the circular plate 17 makes the sleeve 18 close to the side of the rotating plate 5. The inner tube 16 is limited by the circular plate 17, and the sleeve 18 is rotated. The spiral effect of the sleeve 18 and the circular plate 17 makes the sleeve 18 close to or away from the rotating plate 5.

[0036] When the sleeve 18 approaches the rotating plate 5, the rotating sleeve 18 drives the multiple rubber strips 20 to approach the side of the rotating plate 5 until the rubber strips 20 touch the side of the rotating plate 5. The sleeve 18 cooperates with the rotating plate 5 to squeeze the rubber strips 20 until the sleeve 18 can no longer approach the rotating plate 5. At this time, the sleeve 18 is limited on the side of the rotating plate 5, and the sleeve 18 completes the limitation of the end of the deflection plate 8 through the circular plate 17 and the inner tube 16.

[0037] When the rotating rotating rod 12 causes the two opposite sliders 13 to separate from each other, the slider 13 uses the protruding rod 15 to drive the bottom ends of the two rotating plates 5 to separate from each other. Since the limiting component limits the end of the deflection plate 8, the other end of the deflection plate 8 moves up on the surface of the other rotating plate 5. At this time, the deflection plate 8 is deflected, and the deflected I-beam uses the hose 3 to deflect the spray head 4.

[0038] The side of the rotating plate 5 is provided with a side groove 21, and the inner tube 16 corresponds to the side groove 21 penetrating the rotating plate 5, and the inner tube 16 moves up and down inside the side groove 21 of the rotating plate 5. The middle of the rotating plate 5 is provided with a slide groove 22, and the end of the deflection plate 8 is sleeved on the surface of the inner tube 16 through the slide groove 22. When the sleeve frame 18 is away from the rotating plate 5, the sleeve frame 18 drives the rubber strip 20 away from the side of the rotating plate 5, and the limiting component does not limit the deflection plate 8.

[0039] When the rotating rotating rod 12 makes the two relative sliders 13 approach each other, the distance between the bottom ends of the two rotating plates 5 gradually decreases. At this time, the end of the deflection plate 8 moves down inside the slide groove 22 of the rotating plate 5, and the inner tube 16 at the end of the deflection plate 8 moves down inside the side groove 21 of the rotating plate 5. The downward-moving deflection plate 8 drives the paddle plate 7 to approach the spray head 4. In the process of the bottom ends of the two rotating plates 5 approaching each other, the arc frame 6 is used to move the water tank 2 upward. The upward-moving water tank 2 drives the spray head 4 to move upward using the hose 3. At this time, the paddle plate 7 is limited to the top of the spray head 4 to avoid the spray head 4 from swinging around due to the movement of the mobile bracket 1, thereby preventing the adjacent spray heads 4 from being damaged by collision.

[0040] exist Figures 5 to 8 In the figure, the surface of the inner tube 16 is provided with two side grooves, an inner arc plate 23 is placed inside the side groove, a spring piece 24 is fixed to the outer side of the inner arc plate 23, and the outer end of the spring piece 24 is in contact with the end of the deflection plate 8, a clamping rod 25 is provided inside the side groove, the end of the inner arc plate 23 is sleeved on the surface of the clamping rod 25, a wedge block 26 is provided on the inner concave surface of the inner arc plate 23, the inner side surface of the wedge block 26 is set as an inclined surface, and the inner side of the outer side surface of the circumference of the insertion rod 19 is in contact with the inclined surface of the wedge block 26. When the rotating sleeve 18 approaches the rotating plate 5, the rotating sleeve 18 causes the insertion rod 19 to gradually insert into the inner tube 16, and the inwardly moving insertion rod 19 slides on the inclined surface of the wedge block 26, and the insertion rod 19 uses the wedge block 26 to squeeze the inner arc plate 23, and the inner arc plate 23 rotates on the surface of the clamping rod 25. The rotating inner arc plate 23 cooperates with the inner side wall of the end of the deflection plate 8 to squeeze the spring piece 24, and the elastic force of the spring piece 24 is used to provide a damping effect for the rotation of the deflection plate 8 to prevent the deflection plate 8 from rotating arbitrarily.

[0041] After the deflection of the spray head 4 is completed, when the limiting component limits both ends of the deflection plate 8 on the rotating plate 5, the elastic force of the spring sheet 24 provides a damping effect for the rotation of the deflection plate 8, thereby preventing the deflection plate 8 from rotating. In addition, the sleeve frame 18 uses the rubber strip 20 to limit the end of the deflection plate 8 to prevent the I-frame from moving, making it convenient for the movable spray head 4 to spray the sand.

[0042] The present invention also improves a mixed seeding method for restoration of degraded vegetation in sandy land, referring to Figures 1 to 8 As shown, the method uses the above-mentioned mixed seeding device for restoration of degraded vegetation in sandy land, and includes the following steps:

[0043] S1, the water tank 2 is installed on the top of the two arc frames 6 through fastening components. At this time, the mobile bracket 1 supports the water tank 2 through the rotating plate 5 and the arc frames 6. At this time, the mobile bracket 1 moves on the ground using wheels.

[0044] S2. The connecting component adjusts the distance between the bottom ends of the two rotating plates 5. Since the top end of the rotating plate 5 is hinged to the side, the rotating rotating plate 5 drives the deflection plate 8 to rotate using the limiting component. The rotating deflection plate 8 causes the dial plate 7 to rotate synchronously. The dial plate 7 uses the hose 3 to deflect the spray head 4, thereby increasing the spraying range of the spray head 4.

[0045] S3, the moving support 1 drives the hose 3 to move synchronously by using the paddle 7, and the sowing liquid in the water tank 2 is sprayed on the surface of the sand through the spray head 4 at the bottom of the hose 3, so as to irrigate the sand.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
