[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4The utility model discloses a slotting machine fender, comprising a slotting machine body 1, an anti-skid layer 11 is arranged on the outside of the slotting machine body 1, a worker grasps the anti-skid layer 11 with his hand, drives the device to perform slotting work, the anti-skid layer 11 is made of rubber with a high friction coefficient, improves the friction between the hand and the anti-skid layer 11, and prevents slipping, a motor 2 is installed on the left part of the slotting machine body 1, a threaded hole is arranged on the front part of the motor 2, and a slotting blade 3 is threadedly connected with a bolt, the slotting blade 3 is installed on the motor 2 by a bolt threaded connection, and a first fender 4 is arranged on the front part of the left part of the slotting machine body 1 to shield the friction generated during slotting. Mud, a groove 5 is provided at the rear of the first fender 4, the slotting blade 3 is in the groove 5 of the first fender 4, and a gap is provided between the slotting blade 3 and the inner wall of the groove 5, when the motor 2 drives the slotting blade 3 to rotate, the slotting blade 3 will not rub against the groove 5, the first fender 4 is made of plastic with high smoothness, which is convenient for cleaning the first fender 4 later, a slide groove 6 is provided at the front of the first fender 4, and a second fender 7 is slidably connected in the slide groove 6, the second fender 7 is made of plastic with high smoothness, which reduces the friction between the second fender 7 and the slide groove 6, and a gap is provided between the second fender 7 and the slotting blade 3 to prevent the second fender When 7 slides up and down in the slide groove 6, it rubs against the rotating slotting blade 3. Several springs 8 are arranged on the upper part of the second mud guard 7. The upper parts of the several springs 8 are connected to the upper part of the slide groove 6. The lower part of the second mud guard 7 is rotatably connected to several rollers 9 through several rotating shafts. The several rollers 9 are in contact with the wall or the ground to be slotted. Through the slotting work of the staff, the rollers 9 rotate on the wall or the ground, and as the depth of the slotting increases, the several springs 8 on the upper part of the second mud guard 7 stretch to push the second mud guard 7 to slide out of the slide groove 6, so that the several rollers 9 on the lower part are always in contact with the wall or the ground, thereby ensuring that the second mud guard 7 always blocks the slotting blade 3. The outside is covered with mud, thereby improving the effect of blocking mud. Several rollers 9 are made of stainless steel with high smoothness, which reduces the friction between the rollers 9 and the wall or the ground. A threaded hole is set at the front of the first mudguard 4, and a fastening bolt 10 is threadedly connected. The rear end faces of the fastening bolts 10 are in contact with the front end faces of the first mudguard 4. When it is necessary to accurately control the cutting depth of the slotting blade 3, it is only necessary to adjust the distance that the second mudguard 7 slides out of the slide groove 6, and then tighten the fastening bolts 10 to perform the slotting work. When the several rollers 9 at the bottom of the second mudguard 7 are in contact with the wall or the ground, the set slotting depth is reached.
[0022] To sum up, when the mudguard of the slotting machine is in use, the staff loosens the fastening bolt 10 when slotting the wall or the ground, stretches several springs 8 to their original state, and then starts the motor 2. The motor 2 rotates, driving the slotting blade 3 to rotate, and then slotting is performed. At the same time, several rollers 9 contact the wall or the ground and rotate. As the slotting depth increases, the rollers 9 continue to roll on the wall or the ground, and the second mudguard 7 slides into the slide groove 6 to continuously block the soil. After the slotting is completed, the motor 2 can be turned off. When it is necessary to slot the set slotting depth, it is only necessary to adjust the distance that the second mudguard 7 slides out of the slide groove 6, and then tighten the fastening bolt 10 to perform the slotting work. When the several rollers 9 at the bottom of the second mudguard 7 contact the wall or the ground, the set slotting depth is reached.
