Description

Technical Field

[0001] The utility model belongs to the technical field of ecological protection windbreak and sand fixation machinery, and specifically relates to a self-propelled multifunctional grass grid sand barrier equipment. Background Art

[0002] At present, the prevention and control measures for land desertification are mainly divided into three types: biological control measures, enclosure measures and engineering control measures. The first two measures are to try to increase the plant coverage on the desert surface and gradually achieve desertification control. However, the real desert is not a static sand land. There are some large and highly mobile sand dunes on the desert surface. In the upwind area, the sand dunes move and spread under the operation of wind, eroding the green land. Therefore, engineering control measures are needed to prevent the movement of sand dunes. The most typical and effective engineering measure is to set up sand barriers to fix the sand dunes. Grass grid sand barriers to fix sand are the most effective method in engineering sand fixation that has been proven in practice.

[0003] At present, the mechanization level of existing grass grid sand control sand barriers is very low, and they mainly rely on manual or semi-mechanized operations. The overall sand fixation effect is poor, the labor intensity is high, the progress of sand control is slow, and a lot of manual labor is invested. Moreover, the overall practicality of existing sand control equipment is poor, and it has not been promoted and applied. In addition, it is an inevitable trend for traditional manual sand control to develop towards mechanization, intelligence, and integration.

[0004] Therefore, in order to solve this series of problems, it is necessary to design a self-propelled multifunctional grass grid sand barrier equipment. First of all, the equipment must have a chassis foundation that is suitable for walking in the desert to ensure the equipment's driving performance in the sand. Secondly, it must be able to adapt to the straw mat rolls and loose grass compression used in the sand control process, achieving dual uses of one machine. Finally, the entire equipment is easy, simple, and economical to operate, and has good promotion properties, thereby promoting the mechanization of desert control. Utility Model Content

[0005] The utility model aims to provide a self-propelled multifunctional grass grid sand barrier device to solve the problem that the existing grass grid device has poor mechanization and cannot realize multi-purpose.

[0006] The technical solution of the present utility model is: a self-propelled multi-functional straw checkerboard sand barrier device, including a double-track chassis. The double-track chassis includes a chassis frame, and rubber tracks are provided on both sides of the chassis frame. Tensioning devices are provided at the front and middle positions of the rubber tracks. An engine, a traveling power device, a driving operation platform, and a hydraulic operation device are respectively provided on the double-track chassis. A grass pressing disc mechanism and a straw curtain mounting rack are respectively provided at both ends of the double-track chassis. The grass pressing disc mechanism is connected to the chassis frame through a grass pressing disc oil cylinder. A straw curtain reel is movably provided on the straw curtain mounting rack. A liftable guiding rubber wheel mechanism is provided at the rear position below the straw curtain mounting rack. The tail end of the guiding rubber wheel mechanism is connected to the chassis frame through a guiding wheel oil cylinder. An adjustable line marking device is provided at the front end of the straw curtain mounting rack.

[0007] As a further improvement of the present utility model, the straw curtain mounting rack includes a fixed main frame. A rotating frame is connected to the front end of the fixed main frame through a pin shaft. Straw curtain frame oil cylinders are provided at the middle positions on both sides of the rotating frame. The other ends of the straw curtain frame oil cylinders are connected to the middle of the fixed main frame. Straw curtain quick installation side plates are provided on both sides at the front end of the rotating frame, and symmetrical long strip waist-shaped slots are opened on both sides of the straw curtain quick installation side plates. The straw curtain reel is clamped on the long strip waist-shaped slots.

[0008] As a further improvement of the present utility model, the grass pressing disc mechanism includes a grass pressing disc frame and a toothed grass pressing disc. A rotating shaft is provided at the end of the grass pressing disc frame. The toothed grass pressing disc and a grass pressing disc fixing plate are integrally arranged on the rotating shaft through a bearing seat.

[0009] As a further improvement of the present utility model, the guiding rubber wheel mechanism includes a guiding wheel frame. An oil cylinder mounting seat is provided on the guiding wheel frame. A rubber wheel is provided at the middle position at the end of the guiding wheel frame.

[0010] As a further improvement of the present utility model, a foldable seat is provided on the driving operation platform, and a sunshade is provided above the foldable seat.

[0011] The purpose of the present utility model is to solve the problem of difficult mechanized promotion of sand control. By redesigned the chassis structure, it can meet the driving requirements of most deserts. Design simple operation and functional components that can press and control both scattered grass and straw curtains. At the same time, the overall cost of the machine is cheap and easy to maintain, suitable for large-scale promotion, and finally solve the problem of difficult mechanical sand control.

[0012] The present utility model also has the following beneficial effects:

[0013] 1. Compared with manual sand control by pressing straw checkerboards, the utility model greatly improves production efficiency, about 6-8 times that of manual work, which can effectively liberate productivity. Secondly, the hydraulic cylinder exerts downward pressure on the straw pressing plate, and the depth of straw pressing is greater than that of manual shoveling. In addition, the depth of straw pressing can be freely adjusted according to the slope of different sand lands through the cylinder. Therefore, the straw pressing effect of the utility model is far better than that of manual work. Finally, due to the soft ground condition in the desert, it is very laborious for people to walk on it. Using the utility model can effectively reduce the labor intensity of manual work.

[0014] 2. Compared with the existing semi-mechanized hand-held loose straw pressing machine, the utility model does not require manual walking in the desert, reducing labor intensity. Compared with the single loose straw pressing of the hand-held type, the utility model can not only achieve loose straw pressing, but also achieve the pressing of straw curtain rolls. At the same time, the guiding rubber wheel mechanism under the straw curtain roll can effectively ensure the centering degree of the straw curtain, making the straw curtain pressing effect better.

[0015] 3. The structure of the utility model is small and compact. While having a relatively high ground clearance, it maintains a relatively low center of gravity of the whole machine, which can effectively ensure the passability during operation and driving in the desert, and can also effectively prevent the occurrence of side slip and tipping risks. Coupled with the wide-section crawler belt, it can maximize the driving performance of the equipment during sand control operations. The actions of all functional components are realized through the hydraulic valve operating rod, which is convenient and easy to operate.

[0016] 4. The innovative front-laying and rear-pressing structural design. When pressing the straw curtain roll, after the straw curtain is laid on the sand surface, the rubber crawler belt will partially press on the straw curtain, and then the equipment moves forward. The straw curtain is equivalent to the equipment moving backward, and the straw curtain pressing will only be formed after the straw curtain reaches the straw pressing plate. During this process, the crawler belt of the equipment will always press on the straw curtain, thereby increasing the contact area of the whole machine on the sand surface, increasing the friction force when the equipment climbs the slope, avoiding slipping, and at the same time not affecting the straw checkerboard pressing.

[0017] 5. The design of the adjustable line-drawing device can effectively solve the problem of the equipment walking deviation in the desert. Because according to the requirements of the sand control process, the sizes of the straw checkerboards should be kept as consistent as possible to obtain high-quality straw checkerboard sand barriers.

[0018] 6. The outer edge of the straw pressing plate is designed with semi-circular teeth, which is more conducive to the depth of straw pressing, making the straw checkerboard pressing effect better.

[0019] 7. At present, there is no straw checkerboard sand barrier equipment with relatively mature technology and large-scale promotion on the market. Compared with some sand control machines that exist only in concepts and drawings, the overall structure of the utility model is relatively simple, easy to operate, with practical functions and low cost. It is very suitable for large-scale promotion and use, combining functionality and economy, and can effectively contribute to the mechanization process of straw checkerboard sand control.

An engine 2, a walking power device 3, a driving operation platform 4, and a hydraulic operation device 13 are respectively provided on the double-track chassis 1. A grass pressing plate mechanism 7 and a straw curtain mounting frame 9 are respectively provided at both ends of the double-track chassis 1. The grass pressing plate mechanism 7 is connected to the chassis frame 101 through a grass pressing plate oil cylinder 8. A straw curtain reel 905 is movably provided on the straw curtain mounting frame 9. A liftable guiding rubber wheel mechanism 10 is provided at the rear position below the straw curtain mounting frame 9. The tail end of the guiding rubber wheel mechanism 10 is connected to the chassis frame 101 through a guiding wheel oil cylinder 12. An adjustable scribing device 11 is fixedly connected to the front end of the straw curtain mounting frame 9.

[0031] The double-track chassis 1 has a relatively large approach angle and departure angle of the tracks, and the overall ground clearance is relatively high. The engine 2 is installed in a sunken manner at the front end of the double-track chassis 1 and is connected by bolts. The rubber tracks have a relatively large width and use a single-character pattern. The adjustable scribing device 11 can freely adjust the size according to the different sizes of the straw checkerboards in the sand control process.

[0032] The straw curtain mounting frame 9 includes a fixed main frame 901. A rotating frame 903 is connected to the front end of the fixed main frame 901 through a pin shaft 902. Straw curtain frame oil cylinders 904 are provided at the middle positions on both sides of the rotating frame 903. The other ends of the straw curtain frame oil cylinders 904 are connected to the middle of the fixed main frame 901. Straw curtain quick installation side plates 906 are provided on both sides of the front end of the rotating frame 903. Symmetrical long strip waist slots are opened on both sides of the straw curtain quick installation side plates 906. The straw curtain reel 905 is clamped on the long strip waist slots.

[0033] Within the stroke of the straw curtain frame oil cylinder 904, the rotating frame 903 of the straw curtain mounting frame 9 can freely lift and lower. The straw curtain reel 905 on the straw curtain mounting frame 9 can be lowered to a position where the distance from the lowest point to the ground is less than the radius of the straw curtain roll, which is convenient for easily installing the straw curtain roll.

[0034] The grass pressing plate mechanism 7 includes a grass pressing plate frame 701 and a toothed grass pressing plate 703. A rotating shaft 702 is provided at the end of the grass pressing plate frame 701. The toothed grass pressing plate 703 and a grass pressing plate fixing plate 704 are integrally arranged on the rotating shaft 702 through a bearing seat 705. The grass pressing plate mechanism 7 can freely lift and lower within the stroke of the grass pressing plate oil cylinder 8.

[0035] The guiding rubber wheel mechanism 10 includes a guiding wheel frame 1001, on which there is an oil cylinder mounting seat 1003. In the middle of the end of the guiding wheel frame 1001, there is a rubber wheel 1002. The guiding wheel oil cylinder 12 is clamped in the oil cylinder mounting seat 1003 to prevent detachment during the operation movement. Within the stroke of the guiding wheel oil cylinder 12, the guiding rubber wheel mechanism 10 can freely lift and lower, and the rubber wheel 1002 can freely rotate.

[0036] On the driving operation platform 4, there is a foldable seat 5, and above the foldable seat 5, there is a sunshade 6.

[0037] When the utility model is working, according to the different types of grass pressing, it is divided into two working modes, namely loose grass pressing and straw curtain pressing. When pressing the grass checkerboard with loose grass, first, it is necessary to manually lay the required rice straw for pressing at the predetermined position, and then start the equipment. Through the hydraulic operating device 13, control the corresponding oil cylinder to raise the guiding rubber wheel mechanism 10 and the straw curtain mounting frame 9 to the highest position. At the same time, remove the adjustable marking device 11, and then place the equipment across the laid loose grass, making the center of the toothed grass pressing disc 703 align with the center line of the loose grass. Control the oil cylinder to lower the grass pressing disc mechanism 7 to the required grass pressing depth. Subsequently, the equipment travels, driving the toothed grass pressing disc 703 forward to press the grass into the middle grass pressing sand, and the two sides leak to the ground, thus forming the sand barrier edge of the grass checkerboard. Finally, through horizontal and vertical pressing, a standard grass checkerboard sand barrier can be formed.

[0038] When pressing the grass checkerboard with the straw curtain roll, according to the requirements of the grass checkerboard size in the sand control process, first adjust the size of the adjustable marking device 11 to the operation requirement size, and then start the installation of the straw curtain roll. Pass the straw curtain reel 905 through the center of the straw curtain roll and place it at the front end of the equipment. Subsequently, start the equipment, control the lifting of the straw curtain frame oil cylinder 904 through the operating rod to lower the straw curtain mounting frame 9 to the lowest position, and then roll the straw curtain roll with the straw curtain reel 905 above the quick straw curtain installation side plate 906 at the front end of the straw curtain mounting frame 9, and make the straw curtain reel 905 align with the long strip waist groove position of the straw curtain mounting frame 9. Subsequently, control the operating rod to raise the straw curtain mounting frame 9, and at the same time raise the guiding rubber wheel mechanism 10. Then, open the head of the straw curtain roll and extend a part of the straw curtain to press it under the guiding rubber wheel mechanism 10. At this time, let the equipment move forward, and through the rolling of the rubber wheel 1002, the straw curtain roll can be spread on the sandy land. Then, appropriately adjust the lifting of the end grass pressing disc mechanism 7, and through horizontal and vertical driving and pressing, a grass checkerboard sand barrier pressed by the straw curtain can be formed.
