[0034] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings.

[0035] Please refer to Figure 1 And Figure 2 , the present invention provides a grooving device for aerated concrete blocks, including a protective box 1, a guide rail 2, a dust removal chamber 3, a grooving component 4, a speed-limiting component 5, a front baffle 6, a limit component 7 and a rear baffle 8;

[0036] The guide rail 2 is used to convey aerated concrete blocks. When the size of the aerated concrete block is 600mm * 200mm * 200mm, the width of the guide rail 2 is 200mm; the guide rail 2 is fixed on the upper part of the protective box 1, the guide rail 2 is arranged obliquely, and a plurality of rollers 202 are installed on the guide rail 2, so that the aerated concrete blocks placed on the guide rail 2 can move towards the grooving assembly 4 under the action of gravity.

[0037] As Figure 3 shown, a dust removal chamber 3 is opened in the lower part of the protective box 1. The grooving assembly 4 includes a grooving motor 401, a mounting shaft 402 and a saw blade 403. The grooving motor 401 is fixedly installed on the protective box 1. The output end of the grooving motor 401 is connected and fixed to the mounting shaft 402. The mounting shaft 402 is rotatably connected to the protective box 1. The saw blade 403 is fixedly installed on the mounting shaft 402. A communication groove 201 is opened on the guide rail 2. There are two communication grooves 201 and two saw blades 403. The distance between the two saw blades 403 is 100mm. The saw blade 403 passes through the communication groove 201 upward, and the length extending out of the communication groove 201 is 6mm.

[0038] The grooving motor 401 is used to drive the mounting shaft 402 to drive the saw blade 403 to rotate. When the aerated concrete block moves along the guide rail 2 to the upper part of the grooving assembly 4, the saw blade 403 can groove the bottom of the aerated concrete block. Since the aerated concrete block is limited in the guide rail 2, the quality of grooving can be guaranteed, and manual grooving can be avoided, so as to prevent the shape of the groove on the surface of the aerated concrete block from not meeting the requirements of planting steel bars.

[0039] As Figure 3 shown, a front baffle 6 is arranged above the guide rail 2 and is rotatably connected to the feeding port of the protective box 1. The protective box 1 is fixedly connected with a first limiting rod 101. The first limiting rod 101 is located on the closing side of the front baffle 6. A first elastic element 102 is installed in the protective box 1. The front baffle 6 is elastically connected to the protective box 1 through the first elastic element 102. When there is no aerated concrete block on the guide rail 2, the first elastic element 102 can push the front baffle 6 to rotate, and the front baffle 6 can abut against the first limiting rod 101 to block the feeding port of the protective box 1.

[0040] As Figure 4 shown, the upper part of the front baffle 6 is fixedly connected with a first rotating shaft 601. The first rotating shaft 601 is rotatably connected to the protective box 1. The bottom of the front baffle 6 is rotatably connected with a rubber roller 603. A ratchet wheel 602 is rotatably connected to the first rotating shaft 601; a limiting assembly 7 installed in the protective box 1 can act on the ratchet wheel 602 to fix the position of the front baffle 6 and prevent the front baffle 6 from being opened.

[0041] As Figure 5As shown, the limit component 7 includes a switch board 701, a second elastic element 702, and a pawl 703. The distance from the bottom of the switch board 701 to the top of the guide rail 2 is less than the height of the aerated concrete block, that is, the distance from the bottom of the switch board 701 to the top of the guide rail 2 is less than 200 mm. The switch board 701 is rotatably installed in the protection box 1 and is elastically connected to the protection box 1 through the second elastic element 702. The pawl 703 is fixedly connected to the opening side of the switch board 701, and the pawl 703 is meshed and connected above the ratchet wheel 602.

[0042] When there is no aerated concrete block on the guide rail 2, the front baffle 6 will abut against the first limiting rod 101. Under the action of the second elastic element 702, the switch board 701 will rotate downward, and the pawl 703 fixedly connected to the switch board 701 can be meshed with the ratchet wheel 602 to prevent the front baffle 6 from opening. At this time, an object on the guide rail 2 with a height lower than the height of the concrete block will not be able to push the front baffle 6 into the interior of the protection box 1, avoiding damage to the saw blade 403.

[0043] Moreover, a rear baffle 8 is rotatably installed at the discharge port of the protection box 1. A second limiting rod 104 is fixedly installed in the protection box 1. The second limiting rod 104 is located on the closing side of the rear baffle 8. A fourth elastic element 105 is installed in the protection box 1, and the rear baffle 8 is elastically connected to the protection box 1 through the fourth elastic element 105. Through the mutual cooperation of the front baffle 6 and the rear baffle 8, the feeding port and the discharge port of the protection box 1 can be blocked, preventing the saw blade 403 from being exposed or the debris generated by the saw blade 403 cutting the aerated concrete block from splashing outward, posing a safety threat to the staff.

[0044] When there is an aerated concrete block on the guide rail 2, the aerated concrete block can push the switch board 701 to rotate upward, so that the pawl 703 moves away from the ratchet wheel 602, and the front baffle 6 can rotate freely under the push of the aerated concrete block. When the aerated concrete block approaches the saw blade 403, the rubber roller 603 at the bottom of the front baffle 6 can contact the top surface of the aerated concrete block. Under the action of the first elastic element 102, the rubber roller 603 will push the aerated concrete block downward, avoiding severe vibration of the aerated concrete block during cutting by the saw blade 403 and affecting the grooving quality.

[0045] As Figure 6 As shown, a spray pipe 301 is fixedly connected in the dust removal chamber 3. A plurality of spray holes 302 are opened on the spray pipe 301. Connect the external water supply mechanism to the spray pipe 301. The spray holes 302 can spray water into the dust removal chamber 3 to play a role in dust removal and can cool the saw blade 403, preventing the temperature from rising during the cutting process of the saw blade 403 and affecting the hardness of the saw blade 403.

[0046] In order to avoid the waste of water resources, the outer side of the nozzle 301 is rotatably connected with a water stop sleeve 303, and the side wall of the water stop sleeve 303 is provided with a water outlet groove 304. The water stop sleeve 303 is rotatably installed in the dust removal chamber 3, and the water stop sleeve 303 is connected to the front baffle 6 through a belt and a pulley. When the front baffle 6 is in a closed state, there is no aerated concrete block above the saw blade 403, and there is no need to spray water for dust removal and cooling. The water stop sleeve 303 can block the spray hole 302 outside the nozzle 301, saving water resources. When there is an aerated concrete block above the saw blade 403, when the front baffle 6 is driven by the aerated concrete block to rotate, the first rotating shaft 601 will drive the water stop sleeve 303 to rotate through the belt and the pulley, so that the water outlet groove 304 rotates to the spray hole 302, and the water body can be sprayed out from the spray hole 302 normally, which plays the role of dust removal and cooling.

[0047] like Figure 7 As shown, the speed limiting component 5 is installed above the guide rail 2, and is used to control the moving speed of the concrete blocks on the guide rail 2; the speed limiting component 5 includes a reduction motor 501, which is fixedly installed on the protective box 1, and the output end of the reduction motor 501 is fixedly connected to the speed limiting disk 502, and a plurality of limiting grooves 503 are opened inside the speed limiting disk 502, and a speed limiting baffle 504 is slidably connected in the limiting groove 503, and the speed limiting baffle 504 is elastically connected to the speed limiting disk 502 through a third elastic element 505; an installation groove 103 is opened on the side wall of the protective box 1, and the speed limiting baffle 504 extends into the protective box 1 through the installation groove 103.

[0048] When the aerated concrete block slides on the guide rail 2, it will first contact the speed limiting baffle 504, so that the aerated concrete block stops in front of the saw blade 403 to prevent the aerated concrete block from colliding with the saw blade 403 and causing damage to the saw blade 403; under the action of the reduction motor 501, the speed limiting disc 502 will drive the speed limiting baffle 504 to rotate, and the speed limiting baffle 504 located at the front of the aerated concrete block will gradually move outward from the mounting groove 103, and the speed limiting baffle 504 located at the rear of the aerated concrete block can enter the protective box 1 through the mounting groove 103, abut against the side of the aerated concrete block, and move into the limiting groove 503 by compressing the third elastic element 505; the friction between the speed limiting baffle 504 and the aerated concrete block is used to control the moving speed of the aerated concrete block, which can facilitate the control of the grooving efficiency and quality of the aerated concrete block.
