After the existing equipment simply removes the residue on the steam-cured bottom plate, it is inconvenient to collect the concrete residue on the surface, so the treatment and recycling of the bottom skin is a relatively troublesome problem. Summary of the Invention

A plurality of second protrusions are arranged in an equidistant array on the hinged rod. The horizontal plate is fixedly connected in the through groove, and the third spring is fixedly connected between the hinged rod and the through groove.

[0011] Preferably, the swing component further includes a square plate and a first spring. The two square plates are respectively fixedly connected to both sides of one end of the steaming bottom plate. The first spring is fixedly connected between the square plate and the placement cavity.

[0018] A process for removing the bottom skin of an aerated concrete body comprises the following steps:

[0019] S1: The external servo motor drives the drive shaft to rotate the two shafts respectively. As the shaft rotates, it drives the piston to move horizontally back and forth in the sealed chamber.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. As the shaft rotates, it drives the piston to move horizontally back and forth in the sealed chamber. When the piston moves to the right, the gas in the sealed chamber is squeezed by the piston and transported to multiple closed chambers through the air inlet pipe, the gas collecting chamber, and the gas delivery pipe. As the gas in the closed chamber continues to increase, it squeezes the slide rod to move downward. As the slide rod moves downward, it can push the scraper from a vertical state to an inclined state and slide on the steaming bottom plate, which has the effect of removing the bottom skin on the upper surface of the steaming bottom plate.

[0023] 2. When the shaft rotates, the protrusions fixed on the two shafts intermittently and staggeredly squeeze the push rods, which push the steaming bottom plate so that the steaming bottom plate swings on the arc-shaped blocks. The bottom skin removed from the surface of the steaming bottom plate can fall to both sides when the steaming bottom plate swings, which is convenient for collecting the residue.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0030] Reference Figure 1-4 , a bottom skin removal device for aerated concrete body, including a mounting frame 1 and a blank clamping machine 2 fixedly connected to the mounting frame 1, the blank clamping machine 2 is located at the upper end of the mounting frame 1 (the blank clamping machine 2 is a prior art and will not be explained in detail here).

[0031] Placement chambers 9 are installed on both sides of the mounting frame 1, and arc blocks 6 are fixedly connected to the two placement chambers 9. Round rollers 4 are rotatably connected to the arc blocks 6, and round rollers 4 are rotatably connected to the arc blocks 6. Limiting grooves are provided on the round rollers 4 and the arc blocks 6. Limiting rods 5 are slidably connected in the limiting grooves. The limiting rods 5 are used to fix the round rollers 4 and the arc blocks 6 to achieve a fixed state of the steaming bottom plate 3. The steaming bottom plate 3 is fixedly connected between the two round rollers 4. A cleaning component is installed on the steaming bottom plate 3. The cleaning component includes a fixed block 15, a scraper 14, The closed cavity 24, the slide rod 25, the second spring 26, and the multiple fixed blocks 15 are respectively arranged in an equidistant array on both sides of the steaming bottom plate 3. The multiple closed cavities 24 are respectively fixedly connected to the fixed blocks 15. The upper end of the slide rod 25 is slidably connected in the closed cavity 24. The scraper 14 is hinged at the lower end of the slide rod 25. The second spring 26 is fixedly connected between the closed cavity 24 and the slide rod 25. As the slide rod 25 moves downward, it can push the scraper 14 from a vertical state to an inclined state and slide on the steaming bottom plate 3, thereby removing the bottom skin on the upper surface of the steaming bottom plate 3.

[0032] The cleaning component also includes a transverse plate 27, a second protrusion 28, a hinge rod 29, and a third spring 30. The fixed block 15 is arranged in a concave shape, and a through groove is provided on the upper side wall of the fixed block 15. The hinge rod 29 is slidably connected in the through groove. A plurality of second protrusions 28 are equidistantly arrayed on the hinge rod 29. The transverse plate 27 is fixedly connected in the through groove. The third spring 30 is fixedly connected between the hinge rod 29 and the through groove. When the second protrusion 28 moves downward with the hinge rod 29, it is limited by the transverse plate 27 and cooperates with the elastic force of the third spring 30 to achieve a state in which the hinge rod 29 moves back and forth left and right, thereby driving the scraper 14 to move back and forth on the steaming bottom plate 3, so as to better remove the bottom skin on the upper surface of the steaming bottom plate 3.

[0033] A swinging component is installed in one of the placement cavities 9, and the swinging component includes a drive shaft 8, a rotating shaft 7, a main gear 21, a slave gear 22, a first protrusion 19, and a push rod 18. The drive shaft 8 passes through the placement cavity 9 horizontally, and the two rotating shafts 7 are rotatably connected in the placement cavity 9. The main gear 21 is fixedly connected to the drive shaft 8, and the two slave gears 22 are fixedly connected to the rotating shaft 7, and the slave gears 22 are meshed with the main gear 21. Therefore, when the drive shaft 8 rotates, it can drive the two rotating shafts 7 to rotate. The two first protrusions 19 are respectively fixedly connected to the rotating shaft 7, and the two push rods 18 are respectively fixedly connected to both sides of one end of the steaming bottom plate 3. The two first protrusions 19 alternately squeeze the push rod 18 back and forth, thereby achieving the swing of the steaming bottom plate 3.

[0034] The swinging component also includes a square plate 16 and a first spring 17. The two square plates 16 are respectively fixedly connected to both sides of one end of the steaming bottom plate 3. The first spring 17 is fixedly connected between the square plate 16 and the placement cavity 9. The first spring 17 is used to reset the steaming bottom plate 3 after swinging.

[0035] A sealed chamber 23 is respectively sleeved on the two rotating shafts 7, and the sealed chamber 23 is fixedly connected to the placement chamber 9. The rotating shaft 7 is provided with a reciprocating thread. The two rotating shafts 7 are respectively threaded with a piston 20, and the piston 20 is slidably connected in the sealed chamber 23. An air intake pipe 10 is fixedly connected between the sealed chamber 23 and the air collecting chamber 11. A manual valve is provided on the air collecting chamber 11. When the manual valve is opened, the gas in multiple closed chambers 24 can be discharged, thereby resetting the scraper 14 under the tension of the second spring 26. A connecting pipe 13 is fixedly connected between the multiple closed chambers 24, and an air supply pipe 12 is fixedly connected between the connecting pipe 13 and the air collecting chamber 11. A circular hole is provided on the sealed chamber 23, and a one-way valve is respectively installed on the circular hole and the air intake pipe 10.

[0036] A process for removing the bottom skin of an aerated concrete body comprises the following steps:

[0037] S1: Under the drive of the external servo motor on the driving shaft 8, the two rotating shafts 7 can be driven to rotate respectively. As the rotating shaft 7 rotates, the piston 20 is driven to move horizontally back and forth in the sealed chamber 23. When the piston 20 moves to the right, the gas in the sealed chamber 23 is squeezed by the piston 20 and transported to the multiple closed chambers 24 through the air inlet pipe 10, the gas collecting chamber 11, and the air delivery pipe 12. As the gas in the closed chamber 24 continues to increase, it squeezes the slide rod 25 to move downward and compresses the second spring 26. As the slide rod 25 moves downward, it can push the scraper 14 from a vertical state to an inclined state and slide on the steaming bottom plate 3, thereby removing the bottom skin on the upper surface of the steaming bottom plate 3;

[0038] S2: When the rotating shaft 7 rotates, the first protrusions 19 respectively fixed on the two rotating shafts 7 intermittently and staggeredly squeeze the push rods 18, and the push rods 18 push the steaming bottom plate 3, so that the steaming bottom plate 3 swings on the arc block 6, and the bottom skin removed from the upper surface of the steaming bottom plate 3 can fall to both sides when the steaming bottom plate 3 swings.

[0039] In the present invention, when in use, when it is necessary to remove the bottom skin of the concrete body on the upper surface of the steam-cured bottom plate 3, the drive shaft 8 is connected to the external servo motor. Under the drive of the external servo motor on the drive shaft 8, the two rotating shafts 7 can be driven to rotate respectively. When the rotating shaft 7 rotates, the piston 20 is driven to move horizontally back and forth in the sealed chamber 23. When the piston 20 moves to the right, the one-way valve on the air inlet pipe 10 is opened and the one-way valve on the circular hole is closed. Therefore, the gas in the sealed chamber 23 is squeezed by the piston 20 through the air inlet pipe 10, the gas collecting chamber 11, and the air delivery pipe 12 to the multiple closed chambers 24. As the gas in the closed chamber 24 continues to increase, it will squeeze the slide rod 25 to move downward and compress the second spring 26. As the slide rod 25 moves downward, it can push the scraper 14 from a vertical state to an inclined state and slide on the steam-cured bottom plate 3, thereby achieving the purpose of removing the bottom skin on the upper surface of the steam-cured bottom plate 3.

[0040] As the scraper 14 moves downward, it can drive the hinge rod 29 to move downward in the through groove. Since the second protrusion 28 is slidably connected to the cross plate 27, when the second protrusion 28 moves downward with the hinge rod 29, it is limited by the cross plate 27 and cooperates with the elastic force of the third spring 30, so that the hinge rod 29 can move back and forth, thereby driving the scraper 14 to move back and forth on the steaming bottom plate 3, so as to better remove the bottom skin on the upper surface of the steaming bottom plate 3.

[0041] At the same time, when the rotating shaft 7 rotates, the first protrusions 19 respectively fixed on the two rotating shafts 7 intermittently and staggeredly squeeze the push rods 18, and the push rods 18 push the steaming bottom plate 3, so that the steaming bottom plate 3 swings on the arc block 6, so that the bottom skin removed from the upper surface of the steaming bottom plate 3 can fall to both sides when the steaming bottom plate 3 swings.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
