Description

Technical Field

[0001] The invention belongs to the technical field of vegetation protection, and in particular relates to a vegetation maintenance device and method for windbreak and sand fixation. Background Art

[0002] Vegetation conservation refers to a series of measures and actions to protect and maintain the ecosystem functions, biodiversity and sustainability of vegetation.

[0003] When planting vegetation in the desert, it is necessary to prevent wind and fix sand for the vegetation. The specific operation is that at the vegetation planting site, the vegetation maintenance device, that is, the grass grid grass presser, is used to press the grass into the sand. The pressed grass forms a series of "walls", thereby achieving the effect of preventing wind and fixing sand. However, when the existing grass grid grass presser is in use, the toothed disc at the rear of the grass grid grass presser is inserted into the sand to press the grass. When it encounters stones in the sand when moving forward, the toothed disc will be lifted up by the stones, thereby trying to lift up the bracket and the vehicle body connected to it. However, since the vehicle body itself is very heavy, the vehicle body cannot be lifted up, and the toothed disc or the bracket is bent and damaged. Summary of the invention

Initially, the cavity is full of water. When the water is conveyed into the cavity, the water is ejected through the spray hole, causing the sealing component to be pushed open, and then sprayed from the spray hole to the grass under the toothed disc. Since the surface of the grass is wetted by the sprayed water, the weight of the grass increases. Therefore, when the toothed disc rises, the grass will not be taken out by the friction between its own surface and the grass, ensuring that the grass can be stably pressed into the sand;

[0018] S3. When the toothed disc passes over the stone, the first spring releases its force and causes the slider and the toothed disc to descend. At this time, the closing component closes the spray hole, and the conveying component stops conveying water, thereby finally achieving the avoidance of the toothed disc after encountering the stone. When the toothed disc encounters the stone, it will not lift up the bracket or the rear side of the machine body, thereby avoiding damage to the bracket or the toothed disc.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The present invention can achieve the avoidance of the toothed disc after encountering a stone, so that the toothed disc will not tend to lift up the bracket or the rear side of the body after encountering a stone, thereby avoiding the bracket or the toothed disc from being damaged. When the toothed disc is avoiding, water can be sprayed on the grass to increase the weight of the grass. Therefore, when the toothed disc rises, the friction between its own surface and the grass will not be used to bring the grass out, ensuring that the grass can be stably pressed into the sand.

[0021] 2. The present invention gathers the sand toward the end of the two toggle plates away from the bracket through the cooperation of a pair of toggle plates, so that the sand can eventually be squeezed into the pit left by the toothed disc through the gap between the ends of the two toggle plates away from the bracket, so that the pressed grass can be covered with sand, further improving the stability of the grass pressed into the sand.

DETAILED DESCRIPTION

[0030] 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.

[0031] The present invention provides a vegetation maintenance device for windbreak and sand fixation, such as Figures 1 to 7 As shown, it includes a body 1, and a sand fixation device is provided at the rear side of the body 1; the sand fixation device includes a bracket 2, a toothed disc 3, a pair of sliders 4, a push rod 5, a first spring 6, a cavity 7 opened inside the toothed disc 3, spray holes 8 equidistantly arranged on the surface of the toothed disc 3 and connected to the cavity 7, a conveying component for conveying water flow into the cavity 7, and a closing component for closing part of the spray holes 8;

[0032] The bracket 2 is connected to the body 1. The bracket 2 is the bracket on the grass grid mower in the prior art. The body 1 is a grass grid mower. The bracket 2 can swing up and down under the drive of the body 1. The slider 4 is slidably arranged in the bracket 2. The two ends of the gear plate 3 are rotatably connected to the slider 4. The push rod 5 is fixed on the top of the slider 4. The top end of the push rod 5 extends to the outside of the bracket 2. The first spring 6 is sleeved outside the push rod 5, and the conveying assembly cooperates with the push rod 5.

[0033] When in use, the machine body 1 drives the bracket 2 to move downward with the slider 4 and the toothed disc 3 into the sand. As the machine body 1 moves forward, the toothed disc 3 moves accordingly to press the grass laid on the sand into the sand, thereby realizing windproof and sand fixation of the sand. As the toothed disc 3 moves; when there are stones in the sand, the toothed disc 3 contacts the stones, and the slider 4 and the push rod 5 rise, compressing the first spring 6 to deform it and generate a force, and at the same time the conveying component works to convey water into the cavity 7. Initially, the cavity 7 is filled with water. When conveying water into the cavity 7, the water is ejected through the spray hole 8, pushing open the closing component, and then sprayed from the spray hole 8 onto the grass below the toothed disc 3. Since the surface of the grass is wetted by the sprayed water, the weight of the grass becomes larger. Therefore, when the toothed disc 3 rises, it will not rely on the friction between its own surface and the grass to bring the grass out, ensuring that the grass can be stably pressed into the sand, and when the toothed disc 3 avoids the stones, the grass will not be brought out to the ground. When the toothed disc 3 passes over the stone, the first spring 6 releases its force and causes the slider 4 and the toothed disc 3 to descend. At this time, the closing component closes the spray hole 8, and the conveying component stops conveying water, thereby finally achieving the avoidance of the toothed disc 3 after encountering the stone, so that the toothed disc 3 will not tend to lift up the bracket 2 and the rear side of the body 1 after encountering the stone, thereby avoiding damage to the bracket 2 or the toothed disc 3.

[0034] like Figures 3 to 6 As shown, the sealing component includes: a ring frame 9, a rubber pad 10, a pair of arc plates 11 and a second spring 12; an annular groove is provided on the outer side of the toothed disc 3, one end of the spray hole 8 passes through the inner wall of the annular groove, a notch is provided on the surface of the ring frame 9, the ring frame 9 is rotatably sleeved outside the annular groove, the inner side of the bracket 2 is symmetrically provided with vertical grooves, one end of the ring frame 9 is slidably arranged in the vertical groove, the rubber pad 10 is fixed to the inner side of the ring frame 9 and fits with the inner wall of the annular groove, both ends of the ring frame 9 are symmetrically provided with transverse grooves, the arc plates 11 are slidably arranged in the corresponding transverse grooves, the two ends of the second spring 12 are respectively fixedly connected to the arc plates 11 and the inner wall of the transverse groove, and the top of the arc plate 11 is provided with an arc surface 13.

[0035] When the toothed disc 3 moves normally along the sand, the arc plate 11 cooperates with the ring frame 9 to prevent the sand from clogging the spray hole 8. When the toothed disc 3 rises when encountering stones, it will bring the ring frame 9 and the arc plate 11 up with it. The water flow sprayed from the spray hole 8 pushes against the arc surface 13 to squeeze the pair of arc plates 11 apart, so that they are separated from each other. At the same time, the arc plate 11 compresses the second spring 12 to deform it and generate a force. When the water flow stops spraying, the second spring 12 releases the force and brings the arc plate 11 back to its original position, so that the spray hole 8 is closed.

[0036] like Figure 3 As shown, the arc plate 11 and the ring frame 9 form a complete circular ring, and the notch is arranged obliquely below the ring frame 9.

[0037] The water can only be sprayed out from the spray holes 8 at the arc plate 11, so that the grass pressed by the toothed disc 3 can be sprayed to wet and increase its weight. The spray holes 8 in contact with the rubber pad 10 cannot spray water.

[0038] like Figures 1 to 7 As shown, the conveying assembly includes: a cylinder body 14, a water tank 15, a hard pipe 16, a hose 17, a port 18 connecting the water tank 15 and the cylinder body 14, a one-way valve 19 and a piston 23; the cylinder body 14 is fixed to the top of the bracket 2, the water tank 15 is fixed to the top of the cylinder body 14, the port 18 is located on the top wall of the cylinder body 14, the one-way valve 19 is arranged in the spray hole 8 and the port 18, the piston 23 is arranged in the cylinder body 14, the top of the push rod 5 extends into the cylinder body 14 and is fixedly connected to the piston 23, one end of the hose 17 is connected to the upper part of the cylinder body 14, and the other end is connected to the hard pipe 16, the hard pipe 16 is fixed to the outside of the slider 4 through a connecting plate, one end of the hard pipe 16 passes through the middle of one side of the toothed disc 3 and is connected to the cavity 7 inside it, the hard pipe 16 and the toothed disc 3 are rotatably connected, and a sealing ring is provided at the connection.

[0039] The toothed disc 3 rises with the slider 4, the push rod 5, and the piston 23, squeezing the water in the cylinder 14 outward. At this time, the one-way valve 19 located in the through port 18 is closed, and the water flows into the cavity 7 through the hose 17 and the hard tube 16, so that water is injected into the cavity 7. Then the water flows open the one-way valve 19 located in the spray hole 8 and sprays to the curved surface 13 on the curved plate 11. When the toothed disc 3 goes over the stone and descends, the piston 23 descends accordingly, and water is pumped into the cylinder 14. At this time, the one-way valve 19 located in the through port 18 is opened, and the one-way valve 19 located in the spray hole 8 is closed, and the water in the water tank 15 is pumped into the cylinder 14 through the through port 18.

[0040] like Figure 7 As shown, a movable groove is symmetrically opened on one side of the bracket 2 away from the body 1, and a horizontal plate 20 is slidably installed in the movable groove. The top of the horizontal plate 20 is fixedly connected to the top wall of the movable groove through a third spring 22, and a moving plate 21 for moving sand is fixedly installed on one end of the horizontal plate 20 away from the bracket 2.

[0041] The toggle plate 21 is located below the central axis of the toothed disc 3 , and the two toggle plates 21 are symmetrically arranged. The distance between the two toggle plates 21 at one end away from the bracket 2 is smaller than the distance between them at the other end close to the bracket 2 , and the distance between the two toggle plates 21 at one end away from the bracket 2 is smaller than the thickness of the toothed disc 3 .

[0042] When the bracket 2 with the toothed disc 3 is inserted into the sand, the toggle plate 21 contacts the sand and is partially inserted into the sand. If the surface of the sand contacted by the toggle plate 21 is not soft, the toggle plate 21 cannot move after contacting the sand. As the bracket 2 descends, the third spring 22 is compressed to deform it, so that when the toggle plate 21 cannot descend, the bracket 2 can still move normally to ensure that the toothed disc 3 is inserted into the sand. As the machine body 1 moves forward, the cross plate 20 and the toggle plate 21 move accordingly, and the toggle plate 21 gathers the sand to the end of the two toggle plates 21 away from the bracket 2, so that the sand can finally be squeezed into the pit left by the toothed disc 3 through the gap between the ends of the two toggle plates 21 away from the bracket 2, so that the pressed grass can be covered with sand, further improving the stability of pressing the grass into the sand.

[0043] like Figure 5 and Figure 6 As shown, the pressure of the water flow sprayed from the spray hole 8 is sufficient to push open a pair of arc-shaped plates 11 so that they overcome the elastic force of the second spring 12 and move away from each other.

[0044] The present invention also provides a method for using the above-mentioned vegetation maintenance device for windbreak and sand fixation, comprising the following steps:

[0045] S1. When in use, the machine body 1 drives the bracket 2 with the slider 4 and the toothed disc 3 to move downward into the sand. As the machine body 1 moves forward, the toothed disc 3 moves accordingly to press the grass laid on the sand into the sand, thereby achieving windproof and sand fixation of the sand;

[0046] S2. With the movement of the toothed disc 3, when there are stones in the sand, the toothed disc 3 collides with the stones, so that the slider 4 and the push rod 5 rise to compress the first spring 6 to deform it and generate a force. At the same time, the conveying component works to convey water into the cavity 7. Initially, the cavity 7 is full of water. When the water is conveyed into the cavity 7, the water is sprayed out through the spray hole 8, so that the sealing component is pushed open, and then sprayed from the spray hole 8 to the grass under the toothed disc 3. Since the surface of the grass is wetted by the sprayed water, the weight of the grass becomes larger. Therefore, when the toothed disc 3 rises, it will not rely on the friction between its own surface and the grass to bring the grass out, so as to ensure that the grass can be stably pressed into the sand.

[0047] S3. When the toothed disc 3 passes over the stone, the first spring 6 releases its force and brings the slider 4 and the toothed disc 3 down. At this time, the closing component closes the spray hole 8, and the conveying component stops conveying water, thereby finally achieving the avoidance of the toothed disc 3 after encountering the stone, so that the toothed disc 3 will not lift up the bracket 2 and the rear side of the body 1 after encountering the stone, thereby avoiding the bracket 2 or the toothed disc 3 from being damaged.

[0048] Working principle: when in use, the machine body 1 drives the bracket 2 with the slider 4 and the toothed disc 3 to move downward into the sand. As the machine body 1 moves forward, the toothed disc 3 moves accordingly to press the grass laid on the sand into the sand, thereby realizing windproof and sand fixation of the sand and facilitating the later vegetation maintenance. As the toothed disc 3 moves, when there are stones in the sand, the toothed disc 3 collides with the stones, causing the slider 4 and the push rod 5 to rise to compress the first spring 6 to deform it and generate a force. The slider 4, the push rod 5, and the piston 23 rise to squeeze the water in the cylinder 14 outward. At this time, the one-way valve 19 located in the through port 18 is closed, and the water flows into the cavity 7 through the hose 17 and the hard pipe 16, so that the water flows into the cavity 7. Water is injected into the groove 14, and then the water flow pushes open the one-way valve 19 in the spray hole 8 and sprays to the curved surface 13 on the curved plate 11, so that the pair of curved plates 11 are squeezed apart and separated from each other. At the same time, the curved plate 11 compresses the second spring 12 to deform it and generate a force, and the sprayed water flow is sprayed onto the grass below the toothed disc 3. Since the surface of the grass is wetted by the sprayed water flow, the weight of the grass becomes larger. Therefore, when the toothed disc 3 rises, the grass will not be brought out by the friction between its own surface and the grass, ensuring that the grass can be stably pressed into the sand, so that when the toothed disc 3 avoids stones, the grass will not be brought out to the ground. When the toothed disc 3 passes over the stone, the first spring 6 releases its force to carry the slider 4 and the toothed disc 3. 3 descends, and the piston 23 descends accordingly, pumping water into the cylinder body 14. At this time, the one-way valve 19 located in the through port 18 is opened, and the one-way valve 19 located in the spray hole 8 is closed, and the water in the water tank 15 is pumped into the cylinder body 14 through the through port 18. At the same time, due to the stop of the water jet, the second spring 12 releases the force and brings the arc plate 11 back to the original position, so that the spray hole 8 is closed, and finally the toothed disc 3 is avoided after encountering stones, so that the toothed disc 3 will not tend to lift the bracket 2 and the rear side of the body 1 after encountering stones, thereby avoiding the bracket 2 or the toothed disc 3 from being damaged; when the bracket 2 is inserted into the sand with the toothed disc 3, the toggle plate 21 conflicts with the sand and is partially inserted into the sand. In the sand, if the surface of the sand that the toggle plate 21 contacts is not soft, the toggle plate 21 cannot move after contacting the sand. As the bracket 2 descends, the third spring 22 is compressed to deform it, so that when the toggle plate 21 cannot descend, the bracket 2 can still move normally to ensure that the toothed disc 3 is inserted into the sand. As the machine body 1 moves forward, the cross plate 20 and the toggle plate 21 move accordingly, and the toggle plate 21 gathers the sand to the end of the two toggle plates 21 away from the bracket 2, so that the sand can finally be squeezed into the pit left by the toothed disc 3 through the gap between the ends of the two toggle plates 21 away from the bracket 2, so that the pressed grass can be covered with sand, further improving the stability of pressing the grass into the sand.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.

When the toothed disc (3) passes over the stone, the first spring (6) releases its force to bring the slider (4) and the toothed disc (3) down. At this time, the sealing component closes the spray hole (8), and the conveying component stops conveying water, thereby finally achieving the avoidance of the toothed disc (3) after encountering the stone. When the toothed disc (3) encounters the stone, it will not tend to lift up the rear side of the bracket (2) or the body (1), thereby avoiding the bracket (2) or the toothed disc (3) from being damaged.
