[0001] The utility model relates to the technical field of grass trimmers, in particular to a hand-held self-propelled multi-dimensional grass trimmer. Background Art
[0002] Laying grass in arid desert areas is an effective means of sand control. The technology of laying grass grids in the desert is an effective method of preventing wind and fixing sand summarized in long-term sand control work. After setting up the grass grid sand barrier, the surface roughness is significantly improved compared with the quicksand surface, which greatly weakens the wind speed close to the ground. At the same time, it promotes the formation of sand crust and provides favorable conditions for the growth of sand plants. In addition, wheat straw grid sand barriers also have a certain sand blocking effect.
[0003] Traditional grass grids are made by manually inserting hay into the soil. Therefore, laying grass grids over a large area requires a lot of manpower and tools. The manual laying method is inefficient, and the grass grids have poor quality of penetration depth, which is not suitable for laying grass grids over a large area.
[0004] Therefore, hand-held self-propelled multi-dimensional lawn mowers have become a problem that needs to be urgently solved by the entire society. Utility Model Content

DETAILED DESCRIPTION
[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0026] The utility model is described in detail with reference to the accompanying drawings.
[0027] The utility model provides a hand-held self-propelled multi-dimensional grass trimmer in a specific implementation, including a grass trimmer frame, a power system and a grass trimmer system, wherein the grass trimmer frame is installed on the outside of the grass trimmer system, the power system is used to drive the grass trimmer system, the power system includes an engine 1, a reverse gear 2, a gearbox 3, a bridge 4, two sets of running tires 5 and two sets of clutches 28, the engine 1 is used to connect with the reverse gear 2, the reverse gear 2 is used to connect with the gearbox 3, the gearbox 3 is used to connect with the bridge 4, the bridge 4 drives the running tire 5 on the left side to rotate through a chain transmission device, and the gearbox 3 is used to connect with the running tire 5 on the right side to drive the running tire 5 on the right side to rotate;
[0028] The grass pressing system includes two groups of small grass pressing plates 6 and a group of large grass pressing plates 7 with adjustable height. The top ends of the two groups of small grass pressing plates 6 are connected to the bottom of the grass pressing machine frame. The gearbox 3 drives the large grass pressing plates 7 to rotate through a chain transmission device. The two groups of small grass pressing plates 6 are symmetrically distributed on both sides of the large grass pressing plate 7.
[0029] Example:
[0030] When the utility model is in use, the engine 1 is started, the rotation of the engine 1 drives the reverse gear 2 to rotate, the rotation of the reverse gear 2 drives the gearbox 3 to rotate, the gearbox 3 drives the large grass pressing disc 7 to rotate through double chain transmission, the rotation of the large grass pressing disc 7 drives the bridge 4 to rotate, the rotation of the bridge 4 drives the left tire of the running tire 5 to rotate, and the rotation of the gearbox 3 drives the right turning tire to rotate. When the utility model is traveling on the sand, since the two sand tires and the large grass pressing disc have power and it is a manual hand-held type, all sand slopes with an angle of less than 25 degrees, except for the leeward slope and broken sand, can be walked up and down, left and right without side slipping and turning over.
[0031] Before starting the engine 1, carefully check whether the gasoline, engine oil, and antifreeze are sufficient; check whether the screws are tightened; check whether the circuit is powered normally; check whether each operating lever is flexible. Check whether the oil and water pipes are leaking and whether the oil and water are flowing normally; if there are any inappropriate places found above, they must be solved immediately before starting the engine. The engine is a four-stroke water-cooled gasoline engine, and it needs to be filled with 92-grade gasoline, four-stroke engine oil, blue antifreeze, and general gear oil for the gearbox. Do not add water to the water tank, but add antifreeze.
[0032] The left side handle of the frame handle 10 is provided with a throttle start switch 12, a clutch handle 13 and a reverse gear handle 14. The throttle switch can be controlled by the left handle. The clutch handle 13 is an engine clutch handle, and the key switch 17 is in the middle of the handle.
[0033] A headlight and horn switch 15 and a gear lever 16 are arranged on the right side handle of the handle 10 , and a key switch 17 is arranged on the middle cross bar of the handle 10 .
[0034] When starting the engine 1, first push the battery power switch 19 upwards, then turn on the key switch 17, and when the gear display shows 0 gear, turn the air door switch to the left, then turn the throttle to the left, and finally press the start switch. One minute after the engine starts, turn the air door switch to the right. Before driving, first hold the clutch hand, and then shift gears. At this time, the corresponding gear number will be displayed on the display. If you want to go forward, shift to the forward gear, and if you want to go backward, shift to the reverse gear.
[0035] Before the machine enters the sand, the large grass pressing disc 7 should be raised and fixed in the first circular connection hole 26 on the left and right arc-shaped iron plate 24 seat. When entering the sand for construction, the large grass pressing disc 7 should be lowered and fixed in the second circular connection hole 27 under the arc-shaped iron plate 24 seat. When fixing the large grass pressing disc 7, the 20 screw rods should be tightened with spring pads. The height of the large grass pressing disc 7 can be adjusted through the above operation, so that the fixed height of the large grass pressing disc 7 meets the use requirements.
[0036] Before the machine goes into the desert, first deflate the left and right tires to the point where they can be pressed down by hand. When pressing the sand barrier normally in parallel or downhill, the operator should stretch his arms downward and step on the accelerator, otherwise it will affect the quality of the sand barrier. When going up a sand dune, lift the handlebars slightly upward to allow the left and right tires to touch the ground.
[0037] When taking a break, first release the clutch, then turn off the ignition switch. Wait until the radiator fan stops automatically and the water temperature drops, then turn off the key switch, and finally turn off the battery power switch.
[0038] When the construction is finished and the sand is out, the large grass pressing plate 7 should be raised, and the tires should be fully inflated for walking or loading. When the pressure plate is raised, it is easier to turn right when turning, because only the left wheel axle is equipped with a one-way clutch.
[0039] When the utility model is used, the key points of the sand pressure barrier are as follows:
[0040] Look at the grass line in the distance and aim at the fuel tank filler nozzle, look at the pressure plate in the middle of the frame closely, and make sure to press the pressure plate to the middle of the grass. For operators who have just learned how to operate the machine, drive slowly in the beginning, and then speed up after becoming familiar with it.
[0041] As the machine is equipped with a small grass-fixing pressure plate, when the machine is turning or reversing, you need to lower the handle to let the small grass-fixing pressure plate hang in the air, which will make the operation easier.
[0042] Two 30cm diameter grass-fixing small pressing plates 6 and a powered 85cm diameter blunt-edged large pressing plate 6 are added to the grass-pressing system. When pressing sand barriers, two small pressing plates 6 are used to fix the laid wheat straw or rice straw on the ground (especially when the laying weight is more than 0.2 kg per meter, the effect is particularly obvious), and then the large pressing plate 7 is turned over the grass to press the grass into the sand, so that the large pressing plate 7 cannot push the laid grass forward or sideways, and will not press it into an unqualified sand barrier.
[0043] As can be seen from the accompanying drawings, the fuselage shield 9 and the nose shield 11 structure of the utility model have made the fuselage thinner, while reducing obstructions on both sides of the pressure plate. Therefore, when pressing sand barriers, the operator's field of vision of the middle line of the artificially laid straw can be increased, and the operator can press the middle of the straw more accurately, thereby improving the quality of the sand barriers.
[0044] In order to facilitate grass pressing, the small grass pressing plate 6 is arranged in front of the large grass pressing plate 7.
[0045] In order to facilitate the adjustment of the height of the large grass pressing disc, the periphery of the large grass pressing disc 7 is arranged in a thin sheet-like structure, an arc-shaped iron plate 24 is arranged on the frame 8, and clamping plates 25 are arranged on both sides of the central axis of the large grass pressing disc 7. A first circular connecting hole 26 and a second circular connecting hole 27 are arranged at the top of the arc-shaped iron plate 24. When the clamping plate 25 is connected to the first circular connecting hole 26 on the arc-shaped iron plate 24 by screws, the large grass pressing disc 7 is at the top, and when the clamping plate 25 is connected to the second circular connecting hole 27 on the arc-shaped iron plate 24 by screws, the large grass pressing disc 7 is at the bottom.
[0046] Among them, a locking groove is provided at the bottom end of the locking plate 27 for locking and fixing the central axis of the large grass pressing disc 7.
