Description

Technical Field

[0001] The present application relates to the technical field of sand control equipment, and in particular to a multifunctional grass trimmer. Background Art

[0002] Grass grid laying technology is an effective method of preventing wind and fixing sand. It forms a protective barrier by laying grass (rice straw or wheat straw) into a grid shape, which can effectively slow down wind speed and block wind and sand invasion. At the same time, it increases the roughness of the soil surface, improves the soil's water retention capacity and the survival rate of vegetation. However, traditional grass grid laying operations mainly rely on manual work, which has problems such as high labor intensity, low efficiency and high cost. With the country's increasing attention and investment in ecological environmental protection, the multi-functional grass compactor, as one of the important tools for preventing wind and fixing sand, will continue to expand its market demand. At the same time, with the continuous advancement of technology and the reduction of costs, the application scope and popularity of multi-functional grass compactors will also be further improved.

[0003] The existing technology still has the following problems:

[0004] 1. Traditional grass trimmers have great limitations. The grass trimmer disc is difficult to adjust according to the spacing of the grass, which can easily lead to uneven height of the sand barrier formed by the grass, that is, the heights of the two ends of the grass grid are inconsistent, then its effect of blocking wind and sand will be affected, and the lower end may become a breakthrough for wind and sand invasion, and at the same time affect the size of the grass grid sand barrier. If it is too large, it will affect the wind and sand fixation effect, and if it is too small, it will increase the cost and waste materials, resulting in a significant reduction in the wind and sand fixation effect of the entire grass grid, thereby affecting the overall stability and wind and sand fixation effect of the grass grid. In the actual grass trimming process, there are often stones inside the sand to trim the grass trimmer disc, and the existing grass trimmer disc is too rigid, resulting in deformation of the grass trimmer disc when it comes into contact with the stones, resulting in damage to the grass trimmer disc. At the same time, it is difficult to detect the damage of the grass trimmer disc in time, so that the trimmed grass needs to be reworked, affecting the grass trimming efficiency. In addition, it is difficult to detect the grass trimming depth of the grass trimmer disc during the grass trimming process, so the grass trimmer cannot be trimmed according to the required depth.

[0005] 2. Existing grass trimmers do not have a laying mechanism. The few grass trimmers with a laying mechanism find it difficult to lay the grass neatly as required, which causes the laid grass to tilt. The overall structure of the grass grid will be affected, and its effect of blocking wind and sand will be weakened accordingly. The grass grid will fall over on a large scale when subjected to external forces, and the service life of the grass grid sand barrier will be reduced, affecting the overall wind-proof and sand-fixing effect.

[0017] The technical solution provided by this application has at least the following technical effects or advantages:

[0018] 1. The adoption of the grass pressing component effectively solves the limitation of the traditional grass pressing machine. The grass pressing disc is difficult to adjust according to the spacing of the grass, which may easily lead to uneven height of the sand barrier formed by the grass, that is, the heights of the two ends of the grass grid are inconsistent, so its effect of blocking wind and sand will be affected. The lower end may become a breakthrough for wind and sand invasion, and at the same time, it affects the size of the grass grid sand barrier. If it is too large, it will affect the wind and sand fixation effect. If it is too small, it will increase the cost and waste materials, resulting in a significant reduction in the wind and sand fixation effect of the entire grass grid, thereby affecting the overall stability of the grass grid and the wind and sand fixation effect. In the actual grass pressing process, there are often stones inside the sand to press the grass disc, and the existing grass pressing disc is too rigid, which causes the grass pressing disc to deform when it comes into contact with the stones, thereby causing damage to the grass pressing disc. At the same time, it is difficult to detect the damage of the grass pressing disc in time, so it is necessary to The grass pressing efficiency is affected by reworking the pressed grass. In addition, it is difficult to detect the grass pressing depth of the grass pressing disc during the grass pressing process, so the grass cannot be pressed according to the required depth. The present application adjusts the spacing between the grass pressing disc and the grass laying through the grass pressing component. That is, when adjusting the spacing between the grass pressing discs, the spacing of the grass laying can be changed at the same time, so that two rows of grass can be pressed at one time, which can ensure that the heights of both ends of the grass grid remain consistent, thereby improving the overall stability of the grass grid and the wind and sand fixation effect. The grass pressing disc has a certain flexibility, and can obtain a certain buffering effect when encountering hard stones, thereby preventing the grass pressing disc from curling up. At the same time, it can be discovered in time when encountering hard objects, avoiding the discovery after the operation is completed that some grass grids are unqualified and rework is caused, which wastes time. In addition, the operating depth of the grass pressing disc can be accurately monitored to ensure that the operating depth meets the requirements.

[0019] 2. The use of a laying component effectively solves the problem that the existing grass presses do not have a laying mechanism. The few grass presses with a laying mechanism find it difficult to lay the grass neatly as required, which causes the laid grass to tilt. The overall structure of the grass grid will be affected, and its effect of blocking wind and sand will be weakened accordingly. The grass grid will fall over on a large scale when subjected to external forces, and the service life of the grass grid sand barrier will be reduced, affecting the overall wind and sand fixing effect. The present application can lay the grass neatly and press the grass through the laying component, avoiding the uneven structure of the overall grass grid, which affects the effect of the grass grid in blocking wind and sand, making the grass grid neat after cultivation, and improving the effect of the grass grid in blocking wind and sand when subjected to external forces.

During the specific construction, the meridian sample line perpendicular to the dune contour line is constructed first, and then the latitude sample line along the dune contour line is constructed, and the construction is carried out from the upper part of the dune downward in the order of height or material stacking distance, so as to facilitate material transportation or prevent construction workers from accidentally stepping on the well-laid sand barrier. The rice straw or wheat straw is vertically laid on the sample line, that is, the wheat straw is vertically laid on the meridian and latitude sample lines, and at the same time, rice straw or wheat straw is also placed at the intersection of the meridian and latitude sample lines to form a complete closed grid, thereby forming a straw grid-type sand barrier. The staff drives the grass press machine body 1 in the cab 2 to move, and the roller 4 rotates on the ground to move the whole body. The laying component 6 slides on the first slide trough 5 to adjust the distance between the two laying components 6, and the laying component 6 can discharge materials evenly.

The correction mechanism 65 is used to correct the forage when it is discharged. When the forage is offset, the forage is offset to one side in the inner cavity of the correction frame 651. At this time, the forage exerts a certain squeezing force on the correction frame 651. At this time, the correction frame 651 drives the first slide bar 652 to slide in the inner cavity of the first fixed block 655, so that the first spring 653 is subjected to pressure. Under the elastic force of the first spring 653, the correction frame 651 returns to its original position, so that the correction frame 651 is always located in the middle part of the storage barrel 61.

When it is necessary to adjust the spacing of the grass pressing discs 74, the motor 733 drives the threaded rod 732 to rotate in the inner cavity of the distance adjusting frame 731, and the rotation of the threaded rod 732 drives the distance adjusting block 734 to move on the threaded rod 732. At this time, the spacing between the two grass pressing discs 74 can be read according to the value of the scale line on the outer surface of the distance adjusting frame 731 pointed to by the first pointer 735. At the same time, the movement of the distance adjusting block 734 drives the telescopic rod 82 to move, and the movement of the telescopic rod 82 drives the storage rod 81 to move, and the movement of the storage rod 81 drives the paving assembly 6 to move as a whole, so that the grass to be unloaded can always be laid on the entire lower part of the grass pressing disc 74, so that the grass can stand firmly on the sand after being stressed, that is, when adjusting the spacing of the grass pressing discs 74, the spacing of the grass laying can be changed at the same time, so that two rows of grass can be pressed at one time.

[0042] See also Fig.10 and Fig.11As shown, the buffer mechanism 75 includes a buffer frame 751, a fixing rod 752 is fixedly installed on the inner wall of the buffer frame 751, a sliding seat 753 is slidably connected to the outer surface of the fixing rod 752, a third spring 754 is arranged at the middle part of the fixing rod 752, the third spring 754 is located between the sliding seats 753, one end of the sliding seat 753 is rotatably connected to a connecting strip 755, and the end of the connecting strip 755 away from the sliding seat 753 is rotatably connected to a pressure plate 756, the buffer frame 751 is fixedly connected to the inner wall of the top end of the connecting frame 72, and the pressure plate 756 The sliding seat 753 and the buffer frame 751 are in close contact with the upper surface of the spacing frame 731, and the sliding seat 753 is slidably connected with the buffer frame 751. There are two buffer mechanisms 75, which are respectively located on the inner walls on both sides of the top of the connecting frame 72. When the grass pressing disc 74 squeezes the sand, the third spring 754 will be compressed to a certain extent. When the third spring 754 is selected, it is ensured that the grass pressing disc 74 can still be compressed after squeezing the grass, and it is ensured that the grass pressing disc 74 can still move up when it touches a hard object. When the grass pressing disc 74 touches a hard object, the grass pressing disc 74 is squeezed by the hard object. At this time, if If the grass pressing disc 74 is too rigid, it will be easily damaged. Under the action of the buffer mechanism 75, the grass pressing disc 74 has a certain flexibility. When the grass pressing disc 74 is subjected to force, it drives the grass pressing disc 74 to move upward, and the upward movement of the grass pressing disc 74 drives the distance adjustment mechanism 73 to move upward as a whole. At this time, the distance adjustment frame 731 moves upward, and the second sliding rod 736 slides in the inner cavity of the connecting frame 72, so that the distance adjustment frame 731 squeezes the pressure plate 756. After the pressure plate 756 is subjected to force, it moves toward the buffer frame 751. At this time, the connecting bar 755 rotates and drives the slide seat 753 slides on the fixed rod 752, that is, the two slides 753 squeeze the third spring 754 so that the buffer mechanism 75 as a whole has a buffer force on the distance adjustment mechanism 73, so that the grass pressing disc 74 has a buffering effect when it touches a hard object. When leaving the hard object, the elastic force of the third spring 754 makes the pressure plate 756 return to the away position, and the grass pressing disc 74 squeezes the grass again, so that the grass pressing disc 74 has a certain flexibility effect, and can obtain a certain buffering effect when encountering hard stones, thereby preventing the grass pressing disc 74 from curling.

[0043] See also Fig.11 and Fig.12As shown, the alarm mechanism 76 includes a connecting rod 761, a second pointer 762 is fixedly installed on the top of the connecting rod 761, a button 763 is provided on the upper surface of the distance adjustment frame 731, a limit rod 764 is provided in the inner cavity of the connecting rod 761, a squeezing plate 765 is fixedly installed on the bottom end of the limit rod 764, a second limit block 766 is fixedly installed in the middle part of the limit rod 764, and convex rods 767 are slidably connected at both ends of the second limit block 766. A second jack 768 is provided in the inner cavity of the connecting frame 72, there are two buttons 763, and both are located directly below the squeezing plate 765, the connecting rod 761 and the distance adjustment frame 731 are fixedly connected, and the inner cavity of the second limit block 766 is provided with a second jack 768. The four springs, the protruding rod 767 and the fourth spring are elastically connected, the protruding rod 767 and the second jack 768 are engaged, the connecting rod 761 and the limit rod 764, the extrusion plate 765 and the second limit block 766 are slidably connected, the second pointer 762 points to the scale 77, the alarm 78 and the button 763 are electrically connected, and the pressing of the button 763 controls the alarm 78 to sound an alarm. Under the buffering effect of the buffer mechanism 75, when the grass plate 74 touches a hard object, it will drive the distance adjustment frame 731 to move up. When the distance adjustment frame 731 moves up, it drives the connecting rod 761 to slide in the inner cavity of the connecting frame 72. At this time, the button 763 and the extrusion plate 765 contact and squeeze the button 763, and the button 763 is pressed. The squeezing causes the alarm 78 to sound an alarm, reminding the staff that the grass pressing disc 74 has touched a hard object at this time, and it is necessary to check whether the grass pressing disc 74 is damaged before pressing the grass. The limit rod 764 is pulled by external force in the position of the inner cavity of the connecting frame 72 to ensure that there is a gap between the squeezing plate 765 and the button 763 when the grass pressing disc 74 is pressing the grass normally. When adjusting the position of the limit rod 764 in the inner cavity of the connecting frame 72, the limit rod 764 is pulled by external force to make the protruding rod 767 be stored in the inner cavity of the second limit block 766. At this time, the fourth spring contracts, and the protruding rod 767 and the second socket 768 are disengaged. When moving to the appropriate position, the elastic force of the fourth spring causes the protruding rod 767 to be engaged with the second socket 768 again. The limit rod 764 is closed, so that the limit rod 764 is fixed in the inner cavity of the connecting frame 72 to control the distance between the squeezing plate 765 and the button 763, ensuring that no alarm is sounded during normal grass pressing. The second pointer 762 points to the scale 77 to judge the pressing depth of the grass pressing disc 74, that is, when the grass pressing disc 74 is not pressed down, the second pointer 762 points to the zero scale of the scale 77. Even when the grass pressing disc 74 touches a hard object, the upward movement of the distance adjusting frame 731 will drive the second pointer 762 to move, and the pressing depth of the grass pressing disc 74 can be accurately observed. At the same time, when encountering a hard object, it can be discovered in time to avoid discovering that some grass grid operations are unqualified when the operation is completed, resulting in rework and wasting time.

[0044] In summary, the worker drives the main body 1 of the grass trimmer in the cab 2 to move, and the roller 4 rotates on the ground to make the whole body move. The laying component 6 slides on the first slide groove 5 to adjust the distance between the two laying components 6, and the laying component 6 can discharge the material evenly. The grass pressing component 7 is used to squeeze the middle part of the grass to make the grass stand upright, which has the effect of preventing wind and dust. By placing one end of the grass grid grass on the sand, the grass is squeezed at the lower end of the grass pressing plate 74. When the main body 1 of the grass trimmer moves, the grass pressing plate 74 continues to squeeze the grass. At this time, the grass rotates on the collecting rod 64 and continues to feed. Under the action of the correction mechanism 65, the grass is neatly laid on the sand, ensuring that the grass pressing plate 74 can squeeze the middle part of the grass. When adjusting the distance between the grass, the movement of the grass pressing plate 74 drives the telescopic mechanism 8 to move, and the movement of the telescopic mechanism 8 drives the fixing ring 62 The grass pressing disc 74 is driven downward by the lifting mechanism 71 to squeeze the grass, and the distance adjusting mechanism 73 can adjust the distance of the grass pressing disc 74. The buffer mechanism 75 has a certain buffering effect. When the grass pressing disc 74 touches the stone, the grass pressing disc 74 can move upward to prevent the grass pressing disc 74 from curling and failing to press the grass. When the grass pressing disc 74 touches the stone, the alarm mechanism 76 causes the alarm 78 to sound an alarm, reminding the staff to check the grass pressing disc 74 to prevent the grass pressing disc 74 from being damaged and continuing to work, resulting in incomplete pressing of the grass. The scale 77 is used to monitor the pressing depth of the grass pressing disc 74.
