Description

Technical Field

[0001] The invention relates to the technical field of concrete processing, and in particular to an aerated concrete block trimming device. Background Art

[0002] In the process of producing aerated concrete blocks, a large aerated concrete body is first made through a mold, and then the aerated concrete body is cut into multiple small aerated concrete blocks. Since the mold generally reserves a demoulding angle, the side of the aerated concrete body needs to be cut off to remove the uneven parts. There are also uneven parts on the top of the aerated concrete body, so they also need to be cut off.

[0003] When cutting and trimming the top of the aerated concrete body, the existing cutting equipment generally uses a horizontally arranged circular saw for cutting. Since the thickness of the uneven part is small, the uneven waste material tends to break during the cutting process of the circular saw. When the broken small pieces collide with the high-speed rotating circular saw, they will be blown away by the circular saw, hit the cutting equipment, or even fly out of the cutting equipment, causing harm.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] like Figures 1 to 6 As shown, the first embodiment of the present invention provides an aerated concrete block trimming device, which specifically includes a frame 3, a conveying mechanism 1, a rope saw assembly 2 and a crushing assembly arranged on the frame 3, wherein the conveying mechanism 1 includes two conveyors, and when the aerated concrete body is placed on the conveyor, the aerated concrete body can be moved by starting the conveyor. A slag discharge gap is left between the two conveyors, and a V-shaped slag guide plate 29 is fixed on the frame 3, and the slag guide plate 29 can intercept the waste material crushed by the crushing assembly and guide the waste material into the slag discharge gap.

[0030] like Figure 1 and Figure 2 As shown, the rope saw assembly 2 is horizontally mounted on a frame 3 and is used to cut the top of an aerated concrete body. The rope saw assembly 2 includes a rope saw and a plurality of guide wheels, wherein one of the guide wheels is connected to a power device, and the power device may be a motor. When the power device drives the guide wheels to rotate, the rope saw wound around the plurality of guide wheels begins to rotate in a cycle. The rope saw can be divided into a working section and a circulation section. The working section refers to the portion of the rope saw corresponding to the cutting portion of the aerated concrete body to be cut, and the circulation section refers to the portion of the rope saw that is not in the cutting position. The diameter of the rope saw is generally between 0.6 cm and 1.2 cm. Therefore, the height of the cut groove produced when the rope saw is used to cut the aerated concrete body will also be greater than 0.6 cm.

[0031] The crushing assembly of the present invention can crush the waste generated during the cutting process, making it easier to collect the waste. Figure 2 and Figure 3 As shown, the crushing assembly of the present invention is fixed on the frame 3, and the crushing assembly includes four clamping mechanisms and five chiseling mechanisms. The clamping mechanisms and the chiseling mechanisms are staggered, that is, one clamping mechanism is distributed between two adjacent chiseling mechanisms. The clamping mechanism is used to press against the top of the aerated concrete body from above, and at least includes a pressure wheel 4, which can press against the top of the aerated concrete body from top to bottom. The chiseling mechanism includes at least one chiseling head 5 that can move back and forth, and the end of the chiseling head 5 is relatively flat and can be inserted into the groove. The end of the chiseling head 5 is wedge-shaped. When the chiseling head 5 impacts the groove, it can generate an oblique upward force on the concrete waste above the groove, so that the waste suspended above the groove is disconnected and separated from the aerated concrete body.

[0032] Since the pressure wheels 4 are also provided, the staggered pressure wheels 4 cooperate with the chiseling heads 5 to produce a shearing effect, which further makes it easier for the waste to be broken into small pieces, thereby facilitating collection and processing. It should be noted that the rope saw assembly 2 and the crushing assembly are sequentially distributed along the conveying direction of the conveying mechanism 1, that is, the aerated concrete body is first cut by the rope saw assembly 2 and then cooperates with the pressing mechanism and the chiseling mechanism. The mechanism for realizing the reciprocating movement of the chiseling head 5 can be a cylinder.

[0033] Embodiment 2

[0034] On the basis of Example 1, in order to further improve the crushing effect, Figure 4 As shown, the pressing mechanism of the present invention also includes a cylinder body 6 fixed on the frame 3, a piston rod 7 installed in the rod body with a sliding seal, and a first spring 8 arranged in the cylinder body 6 on the side of the piston rod 7 away from the pressure wheel 4. The pressure wheel 4 is rotatably mounted on the piston rod 7. The piston rod 7 includes a piston and a rod body fixed on the piston, and the piston is slidably sealed and installed in the cylinder body 6. The pressure wheel 4 is rotatably mounted on the end of the rod body extending out of the cylinder body 6. Due to the provision of the first spring 8, under the action of the first spring 8, the pressure wheel 4 can be pushed to press downward, thereby cooperating with the chisel head 5 to crush the waste. The first spring 8 also enables the pressure wheel 4 to have a certain ability to move up and down, which enables the pressure wheel 4 to better adapt to the uneven top of the aerated concrete blank, allowing the pressure wheel 4 to maintain contact with the top of the aerated concrete blank.

[0035] In order to further improve the ability of the pressure wheel 4 to cooperate with the chiseling head 5 to shear the waste, Figure 4 As shown, the pressing mechanism provided in the present invention also includes a reset piston 9 installed in a sliding seal in the cylinder body 6 between the spring and the piston rod 7 and a flow limiting plate 10 fixed in the cylinder body 6 between the reset piston 9 and the piston rod 7, and a flow limiting hole 11 is provided on the flow limiting plate 10. The existence of the flow limiting plate 10 divides the inner cavity of the cylinder body 6 between the reset piston 9 and the piston of the piston rod 7 into two chambers, and the two chambers are connected through the flow limiting hole 11. At the same time, hydraulic oil is injected into both chambers.

[0036] by Figure 4 As a reference, through the above arrangement, the first spring 8 pushes the reset piston 9 downward and squeezes the hydraulic oil in the chamber between the reset piston 9 and the flow limiting plate 10 into the chamber between the flow limiting plate 10 and the piston rod 7 through the flow limiting hole 11, so that the pressing wheel 4 moves downward and contacts the top of the aerated concrete body. When the chisel head 5 impacts and cuts the groove, the waste material transmits force upward. Since it takes a certain amount of time for the hydraulic oil to pass through the flow limiting hole 11, the pressing wheel 4 can be temporarily kept at the limit of the top of the aerated concrete body when the chisel head 5 impacts and cuts the groove, thereby cooperating with the chisel head 5 to form a better shearing effect.

[0037] Embodiment 3

[0038] On the basis of the first and second embodiments, the chiseling mechanism of the present invention further comprises a slide 12 fixed on the frame 3, a sliding part 13 slidably mounted on the slide 12, a crank 14 and a first connecting rod 15 rotatably mounted on the frame 3, wherein the chiseling head 5 is arranged on the sliding part 13, and one end of the first connecting rod 15 is hinged to the crank 14, and the other end is hinged to the sliding part 13. The sliding part 13 can be a rod body, and the chiseling head 5 is fixed on the sliding part 13. In this way, when the crank 14 is driven to rotate by the motor, the sliding part 13 can be driven to reciprocate on the slide 12 through the first connecting rod 15, thereby driving the chiseling head 5 to reciprocate.

[0039] In order to further improve the impact effect of the chisel head 5, the waste material can be broken more easily. Figure 4 and Figure 5 As shown, the sliding portion 13 of the present invention is not a simple rod body, but includes a sliding sleeve 16 slidably mounted on the sliding seat 12, a sliding frame 17 inserted into the sliding sleeve 16, an arc track 18 fixed to the end of the sliding frame 17 away from the first connecting rod 15, a movable cylinder 19 sleeved on the end of the sliding frame 17 away from the arc track 18, a second spring 20 located in the movable cylinder 19, and a second connecting rod 30 whose two ends are respectively hinged to the sliding sleeve 16 and a fixed rod 31 on the chiseling head 5, wherein the chiseling head 5 is slidably mounted on the arc track 18, and the center of the arc track 18 is located at the tip of the chiseling head 5.

[0040] The first connecting rod 15 is hinged on the movable cylinder 19, and the two ends of the second spring 20 respectively abut against the end of the slide 17 and the inner wall of the movable cylinder 19. At the same time, in order to prevent the movable cylinder 19 from being separated from the slide 17, a first through slot 21 is provided on the movable cylinder 19, and a first stopper 22 is fixed on the slide 17, and the first stopper 22 can only slide in the first through slot 21.

[0041] Through the above arrangement, when the crank 14 rotates, the first connecting rod 15 drives the movable cylinder 19 to move. When the movable cylinder 19 does not compress the second spring 20, the second spring 20 can be used to push the slide 17 to move, thereby moving the arc track 18 and the chisel head 5 to impact the waste on the cut groove. When the chisel head 5 contacts the waste, the first connecting rod 15 drives the movable cylinder 19 to continue to move, which compresses the spring, so that the movable cylinder 19 moves leftward relative to the slide 17 and pushes the sliding sleeve 16 to move. The sliding sleeve 16 drives the second connecting rod 30 to move, so that the chisel head 5 slides on the arc track 18. At this time, the chisel head 5 rotates with its tip as the center, thereby digging the waste upward, producing a further impact crushing effect on the waste.

[0042] In order to allow the chiseling head 5 to restore its original angle when resetting, the present invention provides a second through slot 23 on the sliding sleeve 16, and fixes a second stopper 24 passing through the first through slot 21 on the slide 17. The second stopper 24 can slide in the first through slot 21, and a third stopper 25 is fixed on the outer wall of the sliding sleeve 16 located at the second stopper 24 away from the chiseling head 5. A guide rod passing through the second stopper 24 is fixed on the third stopper 25, and a third spring 26 is sleeved on the guide rod between the second stopper 24 and the third stopper 25. In this way, under the action of the third spring 26, the sliding sleeve 16 can be pushed to reset on the slide 17, and then the chiseling head 5 can be rotated to the initial angle through the second connecting rod 30.

[0043] like Figure 3 As shown, in order to reduce or avoid the accumulation of crushed waste in front of the chiseling head 5, a dividing cone 27 is fixed on the side of the chiseling head 5 close to the pressure wheel 4.

[0044] In order to prevent the waste from breaking at the root of the cut groove and causing interference to the rope saw below, the present invention also arranges a pad 28 between the working section of the rope saw and the chiseling head 5. The thickness of the pad 28 is less than or equal to the diameter of the rope saw. Both ends of the pad 28 are fixed on the frame 3. The pad 28 can extend into the cut groove. In this way, when the waste breaks and falls, part of the waste is pressed on the pad 28, thereby reducing or avoiding interference with the rope saw. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. In this way, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
