DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Example 1
[0022] Reference Figure 1 , 2 , 3 and 6, a drain dredging device comprises a fixed plate 1, a movable mechanism is fixed on the fixed plate 1, the movable mechanism comprises a plurality of supporting legs 2, the plurality of supporting legs 2 are evenly and symmetrically fixed on the fixed plate 1, a roller 3 is fixed on each supporting leg 2, and the plurality of rollers 3 are respectively moved on both sides of the drain to easily drive the drain dredging device to move on the drain, thereby saving manpower.
[0023] A cutting mechanism is symmetrically fixed on the fixed plate 1, and the cutting mechanism includes a linear motor 4, which is fixed on the fixed plate 1. An electric telescopic rod 5 is vertically fixed on the slider of the linear motor 4, a fixed rod 6 is fixed on the electric telescopic rod 5, a motor 7 is horizontally fixed on the fixed rod 6, and a cutting knife 8 is vertically fixed on the output shaft of the motor 7. The linear motor 4 and the electric telescopic rod 5 are used to adjust the positions of the motor 7 and the cutting knife 8, so that the cutting knife 8 can accurately cut the grass on the inner wall of the drainage ditch.
[0024] Working principle: When in use, the fixed plate 1 is placed above the drain, and multiple rollers 3 are placed on both sides of the drain, so that the staff can easily move the drain dredging device. When mowing the grass, the positions of the two cutting knives 8 are adjusted through the cooperation of two linear motors 4 and two electric telescopic rods 5, so that the cutting knives 8 are close to the inner wall of the drain, and the two motors 7 are used to drive the cutting knives 8 to rotate respectively, and the two rotating cutting knives 8 are used to cut off the grass growing on the two side walls of the drain, so as to achieve the purpose of cleaning the grass on the inner wall of the drain, avoid the grass on the two side walls of the drain, and prevent the entanglement of the grass and the retention of fallen leaves or dead grass in the water, thereby ensuring the smooth drainage of the drain.
[0025] Example 2
[0026] In Example 1, when the cutting blade 8 is cutting grass, grass may occasionally get entangled with the cutting blade 8. The grass entangled with the cutting blade 8 will directly affect the cutting effect of the cutting blade 8. The method of manually removing the grass from the cutting blade 8 is easy to cut the hand and has poor safety. Figure 1-6As another preferred embodiment of the utility model, the difference from embodiment 1 is that two symmetrically arranged supporting legs 2 are provided with grass removing auxiliary mechanisms, which can remove the grass entangled on the two cutting knives 8 respectively. While having high safety in use, it can also ensure the effect of the two cutting knives 8 when used next time.
[0027] The weeding auxiliary mechanism includes a cylinder 9, which is mounted on one of the supporting legs 2. A connecting plate 10 and a first fixed block 12 are symmetrically and rotatably provided on the cylinder 9. A groove 11 is penetrated through the connecting plate 10, and the cutting knife 8 is inserted into the groove 11. When the cutting knife 8 is mowing the grass, the cutting knife 8 escapes from the groove 11, and the connecting plate 10 is rotated so that the connecting plate 10 rotates between two adjacent supporting legs 2, so that the connecting plate 10 will not affect the use of the cutting knife 8.
[0028] A height adjustment mechanism is fixed on the first fixed block 12, and the height adjustment mechanism includes a first plug-in rod 13. The first plug-in rod 13 penetrates and is slidably arranged on the fixed plate 1. A top plate 14 is fixed on the first plug-in rod 13. Pulling the top plate 14 by hand can drive the cylinder 9 to move on the supporting leg 2, thereby adjusting the height of the cylinder 9 on the supporting leg 2. A positioning mechanism is fixed on the top plate 14 and the fixed plate 1. After the height of the cylinder 9 on the supporting leg 2 is adjusted, the height of the cylinder 9 can be fixed by using the positioning mechanism.
[0029] The positioning mechanism includes a second insertion rod 15, which is inserted through the top plate 14, and a second fixing block 18 is fixed on the second insertion rod 15, and a sleeve 17 is fixed on the second fixing block 18. A limiting rod 16 is inserted in the sleeve 17, and the limiting rod 16 is fixed on the fixing plate 1. By cooperating with the second insertion rod 15 and the top plate 14, the height of the cylinder 9 can be fixed.
[0030] Working principle: When the cutting knife 8 is in use, the linear motor 4 is used to drive the cutting knife 8 out of the groove 11, and the connecting plate 10 is rotated to allow the connecting plate 10 to rotate between two adjacent supporting legs 2 to prevent the connecting plate 10 from affecting the rotation of the cutting knife 8 driven by the motor 7, thereby ensuring the use effect of the cutting knife 8. When the cutting knife 8 is used and grass is entangled, the cutting knife 8 moves to one side, rotates out of the connecting plate 10, and uses the linear motor 4 to drive the upper end of the cutting knife 8 to be inserted into the groove 11. At this time, the height of the cutting knife 8 is at the highest position, and then the top plate 14 is pulled up to allow the top plate 14 to be out of the groove 11. The second insertion rod 15 is pulled out, and the sleeve 17 is moved on the limiting rod 16, so that the sleeve 17 moves to one side with the second insertion rod 15, and the top plate 14 is pressed down, so that the top plate 14 drives the first fixing block 12 and the cylinder 9 to move downward together through the first insertion rod 13, and the connecting plate 10 moves downward together. Since the cutting knife 8 is inserted in the groove 11, the downward moving connecting plate 10 will block the grass wrapped around the cutting knife 8, so that the grass wrapped around the cutting knife 8 can be removed from the cutting knife 8, so as to achieve the purpose of safely cleaning the grass wrapped around the cutting knife 8 and ensure the mowing effect of the cutting knife 8 when it is used next time.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
