[0014] (1) Defects in the positioning method of pole adjustment angle: the
infrared vertical instrument can only project vertical
infrared rays after it is time-consuming to adjust the level, and the manual
push and pull of the powder wall machine is time-consuming and laborious. It must be equal to the
infrared surface; it takes a lot of work, one person adjusts the infrared vertical instrument, and one person pushes and pulls the powder wall machine; the scope of application is narrow, and the angle is limited: there are many frame structure houses at present, and the
brick wall is already a non-load-bearing wall. There are often skewed walls, and the powder wall The machine is positioned vertically at 90 degrees, and many walls cannot be powdered; the walls can be powdered, and the
mortar ash plastered is thin at the bottom and thick at the top, thick and hollow, or detached; the
mortar ash plastered is thick at the bottom and thin at the top, and the plastering board touches the wall ,
ranging from destroying the plastering board to damage the plastering board, and seriously damaging the machine; the error is too large: if the infrared vertical instrument is not adjusted level, there will be errors, and manual adjustments will also have errors; if the angle is not adjusted properly, the quality of the plastering will be poor, and the plastering angle will not fit the wall. gray hollow, detached
[0015] (2) Defects of the hydraulic pole fixing method: the pole is often pulled out, and it is time-consuming, laborious and labor-intensive to
plug in the pole. After the pole is inserted, although it is about 15cm shorter than the roof, it is much higher than the door and the construction hole. To go through the door and the construction hole, two people need to cooperate to pull out and
plug in the poles, beams, etc.; several sets of poles of different lengths need to be spared, which are too heavy and too many, and it is extremely inconvenient to store and transfer; Holding the pole with one hand and stepping on the hydraulic pedal with one foot affects the positioning angle of the pole, which is laborious and time-consuming, and increases the angle deviation of the pole
[0016] (3) During the plastering process, observe the state of the ash hopper for defects: by observing the running state of the ash hopper, judge whether there is any obstacle. When the ash hopper rises, it is stuck by wall nails,
steel bar heads, convex bricks, etc., manually turn off the motor, often broken Ash bucket frame, pull
rope, motor, etc., human-machine unsafe
[0017] (4) The upper
limit switch restricts the rise of the main body. There are defects: when the ash bucket rack is on top of the roof, the roof is uneven, the ash bucket rack touches the convex part, the upper
limit switch does not touch the concave part, the switch fails, the motor does not stop in time, and the ash bucket rack It is easily deformed and damaged due to high force, the pole frame is bent, and the
rope is broken
[0018] (5) There are defects in the conjoined body of the ash bucket and the main motor: when the main body is raised and lowered, there is a great risk of machine
crash and death. Up to 250kg-350kg, serious top-heavy during plastering, the vertical pole is not fixed tightly, or the hydraulic
system is wrong, or the operation is wrong, etc., the machine is inverted, and it is easy to cause accidents
[0019] (6) The main dust hopper can only be lowered to the wheeled
chassis, and the plastering knife is 20cm away from the ground. The pressure of the
cement mortar is not enough, after plastering, the
cement mortar is dusty, hollow, and falls off
[0020] (7) The capacity of the ash hopper is too small, and it is inconvenient to add ash when plastering
[0038] (1) Defects in the positioning method of vertical rod angle adjustment: it takes time and effort to put the guide rail angle iron, and more than two people need to cooperate when the guide rail angle iron is put on the wall powder machine, which is labor-intensive. If you let it go by mistake, the machine will be destroyed; at present, there are many frame structure houses, and the
brick wall is already a non-load-bearing wall, and there are often skewed walls. If the mortar dust is thin at the bottom and thick at the top, thick and hollow, or detached, if the bottom is thick and the top is thin, the plastering board will hit the wall, and the plastering board will be damaged if it is light, and the machine will fall down and hurt people if it is serious; the error is large, and the
DC motor The
inertia of the push rod is large, and the vertical 90-degree fluctuation range of the vertical rod of the powder wall machine is large; As the
vertical angle changes, the quality of plastering will deteriorate; for this reason, adjust the angle positioning, add accessories such as angle irons, store on site, and transfer is inconvenient. As the length of the house varies, it is necessary to equip multiple guide rail angle irons of different lengths
[0039] (2) Pole fixing method and
structural system defects: 1 force-bearing rod, resulting in a small force-
bearing surface, under the vibration of plastering, the square tubes of the two guide rails move and rotate around the point of force, and the powder wall machine cannot be fixed; the roof Uneven, or the ground is uneven and the powder wall machine is skewed. One end of the beam at the top of the pole frame is convex, and the other end and the middle are suspended, so the pole frame cannot be fixed, and it will move and rotate a lot; There are many plastering joints; the fixation is unstable, the vibration force cannot be increased, the plastering is empty, there is a lot of falling off, the fixation is not firm, it cannot be plastered with strong earthquakes, and frequent
rework is required; it is inconvenient to add dust, there are many vertical pipes, and the pipes are narrow , cannot add ash between the poles; transition is inconvenient, the pole frame is higher than the ordinary door after stretching, it is inconvenient to pass through the ordinary door, and it has to be skewed to pass through; the pole frame cannot be removed, the car is closed, and cannot be installed
[0040] (3) During the plastering process, it is difficult to respond in time by observing the running status of the ash hopper to judge whether there is an obstacle, the man-machine is unsafe, and the machine often breaks down
[0041] (4) The upper
limit switch restricts the rise of the main body. There are defects: when the ash bucket rack is on top of the roof, the roof is uneven, the ash bucket rack touches the convex part, the upper limit switch does not touch the concave part, the switch fails, the motor does not stop in time, and the ash bucket rack Damaged by
large deformation under force, bending of vertical pole frame, broken
rope[0043] (6) The capacity of the ash bucket is too small, and it is inconvenient to add ash when plastering
