[0035] The position, at which the rotating plate 101 on the lower side of the support plate 4 is connected with the support plate 4, is farther than the position, at which the rotating plate 101 on the upper side of the support plate 4 is connected with the support plate 4, so that, after the rotating plate 101 on the upper side is rotated and coincides with the support plate 4, the rotating plate 101 on the upper side is prevented from being blocked after being rotated, so that the rotating plate 101 on the lower side cannot be rotated.

[0036] The power assembly comprises a fixed rod 401, a fixed plate 402, a sliding rail 403, a sliding block 404, a motor 405, a rotating wheel 406 and a second rope 407, the backpack 1 is provided with two fixed rods 401 at the back, the two fixed rods 401 are fixedly connected with the fixed plate 402, the fixed plate 402 is boltedly connected with the sliding rail 403, the sliding rail 403 is slidably connected with the sliding block 404, the sliding block 404 is detachably connected with the motor 405, the output end of the motor 405 is fixedly connected with the rotating wheel 406, the second rope 407 is wound on the rotating wheel 406, and the other end of the second rope 407 is fixedly connected with the upper side of the support plate 4.

[0037] The working steps of the above embodiment are as follows: first, the construction personnel fold the support plate 4 and all the parts connected thereto and place them in the backpack 1, so that the construction personnel do not need to hold too many parts, making the present application easier to carry; before starting to hammer the wall, the fixed rod 401, the fixed plate 402, the sliding rail 403 and all the parts connected thereto need to be assembled in front of the wall, then the construction personnel take out the support plate 4 and all the parts connected thereto from the backpack 1 and unfold them, as shown in Figure 2 the second rope 407 is fixed on the support plate 4, then one end of the air pump 3 and the first air suction block 6 are communicated through the air pipe, the water conveying device is communicated with the support plate 4 and the rotating plate 101, then the rotating plate 101 on the upper side of the support plate 4 is driven to rotate towards the support plate 4 by the motor 104 on the upper side of the support plate 4, and then the rotating plate 101 on the lower side of the support plate 4 is driven to rotate towards the support plate 4 by the motor 104 on the lower side of the support plate 4, so that the two second rotating blocks 102 and the first rotating block 5 coincide, then the water conveying device conveys water into the support plate 4 and the rotating plate 101, and the water mist is sprayed out through the first water outlet 4a and the second water outlet 101a, so that the second filter screen 102a and the first filter screen 5a are wetted by the water mist, and then the second filter screen 102a and the first filter screen 5a can adsorb dust, thereby preventing a large amount of dust from being generated towards one direction during subsequent cutting of the wall, so that the dust content in the room increases rapidly, affecting the normal construction environment of the construction personnel, and at the same time, since there are three first filter screens 5a and second filter screens 102a on the first rotating block 5 and the second rotating block 102, the dust settling effect is stronger, when the construction personnel cuts the wall on the left side or the right side of the support plate 4 by using an external cutting machine, and moves during cutting, the support plate 4 and all the parts connected thereto are driven to move synchronously with the construction personnel by the sliding block 404, so that the dust generated during cutting is quickly adsorbed, it should be noted that the construction personnel selects the direction of the cutting machine to cut on the left side or the right side of the support plate 4, and moves up and down, and the support plate 4 and all the parts connected thereto move synchronously by the motor 405;

[0038] After the cutting is completed, the construction personnel clean the first rotating block 5 and the second rotating block 102, then move the support plate 4 to the position where wall breaking is needed next by the motor 405 and the sliding block 404, then rotate the corresponding rotating plate 101 on the upper side of the support plate 4 by the motor 104 on the upper side of the support plate 4, so that the rotating plate 101 on the upper side of the support plate 4 is perpendicular to the support plate 4, then the first air suction block 6 and the second air suction plate 103 are air-sucked by the air pump 3, then the construction personnel start to break the wall, and the dust generated by the wall breaking is carried by the airflow generated by the air suction of the first air suction block 6 and the second air suction plate 103, so that the dust generated by the wall breaking is sucked by the first air suction block 6 and the second air suction plate 103, and at the same time, the water conveying device conveys water into the support plate 4 and the rotating plate 101, and sprays water mist from the first water outlet 4a and the second water outlet 101a to the second filter screen 102a and the first filter screen 5a, so that when the dust passes through the first rotating block 5 and the second rotating block 102, the dust is adsorbed by the water on the second filter screen 102a and the first filter screen 5a, so that the dust cannot float away, thereby completing the dust reduction.

[0039] It should be noted that during the hammering process, when the support plate 4 moves to the position of the legs of the construction personnel, the direction of the hammering of the construction personnel at this time is inclined downward, so the upper rotating plate 101 is rotated by the motor 104 to coincide with the support plate 4, and when the support plate 4 moves to the position of the shoulders of the construction personnel and above, the lower rotating plate 101 is rotated by the motor 104 to coincide with the support plate 4, thereby facilitating the wall breaking operation of the construction personnel, and preventing the construction personnel from hitting the rotating plate 101 when breaking the wall. Embodiment 2

[0040] On the basis of embodiment 1, as shown in Figure 2 , Figure 3 , Figure 8 and Figure 13 , the cleaning assembly is further included, the support plate 4 is connected with the cleaning assembly, and the cleaning assembly is used for cleaning the dust adsorbed on the first filter screen 5a and the second filter screen 102a; the cleaning assembly includes a vibrating plate 202, a cleaning plate 203 and a filtering device 307; the counterweight 8 is fixedly connected with the vibrating plate 202, twenty rectangular air suction holes 202a are arranged on the vibrating plate 202, and the vibrating plate 202 is in communication with the other end of the air pump 3; the vibrating plate 202 is fixedly connected with four cleaning plates 203, and the cleaning plates 203 are provided with bristles; the first filter screen 5a and the second filter screen 102a are cleaned by the cleaning plates 203; the filtering device 307 is in communication between the vibrating plate 202 and the air pump 3, and the filtering device 307 is fixedly connected with the backpack 1, so as to filter the dust and prevent the dust from affecting the air pump 3.

[0041] Further comprising spring 201, push rod 204 and first electromagnet 205; all the first rope 7 is sleeved with a spring 201, and the both ends of the spring 201 are fixedly connected with the support plate 4 and the counterweight 8 respectively; the support plate 4 is bolted with two push rods 204; the telescopic end of all the push rods 204 is fixedly connected with the first electromagnet 205.

[0042] The cleaning assembly further comprises second electromagnet 206; the front side and the rear side of the vibration plate 202 are fixedly connected with four second electromagnets 206; the first rotating block 5 and the second rotating block 102 are inclined through the second electromagnet 206, so that the cleaning plate 203 can better clean the first filter screen 5a and the second filter screen 102a.

[0043] The working steps of the above embodiment are: since the dust will be adsorbed on the first filter screen 5a and the second filter screen 102a when the wall is being broken, and when the dust gradually accumulates, the first filter screen 5a and the second filter screen 102a will be blocked, in the interval when the construction personnel rest while breaking the wall, the rotating plate 101 on the upper side of the support plate 4 is rotated towards the support plate 4, and the air pump 3 is controlled to reverse and the second electromagnet 206 is started, the second electromagnet 206 generates suction force on the first rotating block 5 and the second rotating block 102, and since all the second electromagnets 206 are located above or below the rotating position of the first rotating block 5 and the second rotating block 102, the first rotating block 5 and the rotating plate 101 are inclined, then air is blown through the first air suction block 6 and the second air suction plate 103, since the vibration plate 202 is connected to the other end of the air pump 3, the vibration plate 202 sucks air through the air suction hole 202a, so that the air flow blown out through the first air suction block 6 and the second air suction plate 103 blows off most of the dust on the first filter screen 5a and the second filter screen 102a, then the dust blown off is sucked away through the air suction hole 202a, at this time the support plate 4 and the rotating plate 101 connected water delivery device stop delivering water, so that under the action of the air flow, the first filter screen 5a and the second filter screen 102a gradually become dry;

[0044] Then, the push rod 204 pulls the first electromagnet 205 upward, thereby driving the counterweight 8 upward. When the counterweight 8 moves upward to a distance of two to three centimeters from the support plate 4, the counterweight 8 stops moving upward. At this time, the spring 201 is in a compressed state. Then, by turning off the first electromagnet 205, the first electromagnet 205 no longer attracts the counterweight 8, causing the counterweight 8 to move rapidly downward under the influence of gravity and the pushing force of the spring 201. Then, under the action of the spring 201, it vibrates up and down repeatedly, thereby driving the vibrating plate 202 and all its connected parts to vibrate up and down. Then, the cleaning plate 203 cleans the dust adsorbed on the first filter screen 5a and the second filter screen 102a. Then, the vibrating plate 202 sucks away the dust, and the filter device 307 filters out the dust to prevent the dust from affecting the air pump 3.

[0045] It should be noted that after the rotating plate 101 on the upper side of the support plate 4 is cleaned, the rotating plate 101 on the upper side of the support plate 4 is driven by the motor 104 to rotate away from the support plate 4. When the rotating plate 101 on the upper side of the support plate 4 is perpendicular to the support plate 4, the rotating plate 101 on the upper side of the support plate 4 stops rotating. Then, the rotating plate 101 on the lower side of the support plate 4 is driven by the motor 104 to rotate towards the support plate 4, so that the rotating plate 101 on the lower side of the support plate 4 coincides with the support plate 4, thereby cleaning the second filter screen 102a below. Example 3

[0046] Based on Example 2, such as Figures 9-13 As shown, it also includes a heat dissipation component. The backpack 1 is connected to the heat dissipation component, which dissipates heat from the part of the backpack 1 that comes into contact with the person. The heat dissipation component includes a fan 301 and a fixing block 302. Two fans 301 are bolted inside the backpack 1. Three fixing blocks 302 are fixedly connected to the rear side of the backpack 1. Several ventilation holes 1a are provided on the rear side of the backpack 1.

[0047] The fixing block 302 is set as a hollow block, so that the airflow from the ventilation hole 1a can pass through the fixing block 302, thereby making the blowing effect on the back of the construction worker better.

[0048] It also includes an adjustment component. The backpack 1 is connected to the adjustment component, which is used to adjust the tightness of the shoulder straps 2. The adjustment component includes a rotating rod 303, a pulley 304, and a knob 305. The backpack 1 is rotatably connected to two rotating rods 303. All rotating rods 303 are fixedly connected to two pulleys 304, and two adjacent pulleys 304 are wrapped with the corresponding shoulder straps 2. All rotating rods 303 are fixedly connected to two knobs 305.

[0049] The adjusting block 306 is hollow, and the air pump 3 is communicated with the adjusting block 306, and the adjusting block 306 is communicated with the back strap 2 or the vibrating plate 202.

[0050] The working steps of the above embodiment are as follows: since the movement range of the construction worker is large when the wall is being broken, the backpack 1 is easy to shake, therefore, before the wall is broken, the construction worker rotates the rotating knob 305 to drive the rotating rod 303 to rotate, thereby driving the pulley 304 to rotate to wind the back strap 2, so that the backpack 1 is close to the back of the construction worker, thereby preventing the backpack 1 from shaking greatly to affect the construction worker breaking the wall;

[0051] Since the movement range of the construction worker is large when the wall is being broken, the construction worker is easy to sweat, and the close contact between the backpack 1 and the back of the construction worker makes the construction worker very uncomfortable, therefore, after the back strap 2 is wound, the fixed block 302 can prevent the backpack 1 from being close to the back of the construction worker, and then the fan 301 is rotated to form an air flow in the backpack 1, since the backpack 1 is not close to the back of the construction worker, the air in the backpack 1 flows out from the air vent 1a, thereby blowing the back of the construction worker, and the construction worker is more comfortable;

[0052] Since a lot of concrete debris and brick debris will fall when the wall is broken, a lot of dust will be generated when the concrete debris and brick debris fall, and the dust is not in the range of the first air suction block 6 and the second air suction plate 103, therefore, the dust cannot be adsorbed by the first filter screen 5a and the second filter screen 102a, so that the dust rising will be inhaled by the construction worker, thereby affecting the health of the construction worker, therefore, when the wall is broken, the adjusting block 306 is used to make the air pump 3 communicated with the back strap 2, thereby blowing the air flow through the air outlet 2a to blow away the rising dust, thereby preventing the rising dust from being inhaled by the construction worker;

[0053] It should be noted that the construction worker can make the air pump 3 communicated with the vibrating plate 202 through the adjusting block 306 when cleaning is needed, and the air pump 3 is communicated with the back strap 2 through the adjusting block 306 when the wall is broken.

[0054] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope of the claims.
