DETAILED DESCRIPTION

[0019] In order to enable the above-mentioned purpose, features and advantages of the utility model to be more clearly understood, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0020] The building waste pulverizing device provided by the embodiment solves the problems that the building waste is input into the pulverizer through the feeding hopper, too much feeding leads to poor pulverizing effect, and pulverizing blockage and machine jamming are prone to occur.

[0021] As shown in Figure 1 A building waste pulverizing device, which comprises a pulverization mechanism 1 and a feeding hopper 2.

[0022] The feeding hopper 2 adopts a conventional structure and has a funnel-shaped shell, so that the building waste can pass through more smoothly and smoothly, and problems such as blockage are less likely to occur, thereby improving the conveying efficiency and stability of the building waste.

[0023] The pulverization mechanism 1 comprises a pulverizer body 101 and a pulverization motor 102. The pulverizer body 101 adopts a conventional rolling roller structure pulverizer or a double roller structure pulverizer. The pulverization motor 102 drives the pulverizer body 101 to pulverize the building waste through a transmission part 103.

[0024] The transmission part 103 in the embodiment adopts a conventional belt transmission component.

[0025] AsFigure 1 , Figure 2 As shown, a feeding frame 3 is provided below the feeding hopper 2, and a support frame 4 is fixedly installed at the bottom of the feeding frame 3. The bottom of the support frame 4 is fixedly installed above the feeding port of the crushing mechanism 1.

[0026] like Figure 4 , Figure 5 As shown, an intermittent feeding mechanism 5 is installed inside the feeding frame 3, and a material blocking mechanism 6 is installed inside the support frame 4. Through the cooperation of the intermittent feeding mechanism 5 and the material blocking mechanism 6, construction waste can be fed intermittently, which can better control the amount and speed of waste feeding, avoid the accumulation of waste in the crushing chamber, and reduce the risk of blockage and jamming.

[0027] It should be noted that, in Figure 4 , Figure 5 In the middle, the intermittent feeding mechanism 5 includes a feeding cylinder 501 and two feeding blocks 502. The feeding cylinder 501 is rotatably installed at the center of the feeding frame 3. The feeding blocks 502 are symmetrically arranged on the inner wall of the feeding frame 3. The end face of the feeding blocks 502 is set as arc-shaped, and the arc-shaped surface of the feeding blocks 502 corresponds to the surface of the feeding cylinder 501. A material receiving cavity 503 is opened on the feeding cylinder 501.

[0028] like Figure 2 , Figure 3 As shown, a drive assembly 7 for driving the feed cylinder 501 to rotate is provided at the end of the feed cylinder 501.

[0029] It needs to be further explained that, in Figure 2 , Figure 3 , Figure 4 In the process, the drive assembly 7 set on the feed cylinder 501 includes a cylinder 701, two gears 702 and two racks 703. A platform 705 is fixedly connected to one side of the feed frame 3. The cylinder 701 is mounted on the platform 705. The output end (i.e., piston rod) of the cylinder 701 is connected to a crossbar 706. The two ends of the central shaft of the feed cylinder 501 extend out of the two end faces of the feed frame 3 and are non-rotatably connected to the gears 702. Guide rails 704 are respectively installed on the two end faces of the feed frame 3. The back of the rack 703 is slidably connected to the guide rail 704. The teeth of the rack 703 mesh with the gears 702. The connecting parts of the rack 703 are connected to the two ends of the crossbar 706 via connecting rods 707.

[0030] In this embodiment, the piston rod of the cylinder 701 produces extension and retraction movement under the action of the external compressor to generate high-pressure gas. When the piston rod of the cylinder 701 extends, the connecting rod 707 is driven by the cross rod 706 to move outward, and then the connecting rod 707 pushes the rack 703 to drive the gear 702 to rotate. At this time, the feeding cylinder 501 rotates synchronously with the gear 702, and the material receiving cavity 503 on the feeding cylinder 501 drives the internal construction waste to rotate. When the feeding cylinder 501 rotates by 180°, the construction waste freely falls under the action of its own gravity, realizing intermittent feeding of the waste. After the piston rod of the cylinder 701 retracts, the material receiving cavity 503 on the feeding cylinder 501 rotates back to the material receiving position to receive the construction waste from the hopper 2. By controlling the extension and retraction speed and times of the piston rod of the cylinder 701, the feeding amount and feeding speed of the waste can be well controlled.

[0031] It needs to be further explained that, as shown in Figure 1 , in order to realize safe operation of the gear 702 and the rack 703, as shown in Figure 1 , Figure 2 and Figure 3 , a protective plate 8 shielding the gear 702 and the rack 703 is detachably installed on the guide rail 704.

[0032] It needs to be explained that, in Figure 4 , Figure 5 , the material blocking mechanism includes a material blocking guide block 601, a material blocking plate 602 and a shaft sleeve 603. The material blocking guide block 601 is fixedly installed on one end face of the inside of the support frame 4, and has an inclined material guide surface. The shaft sleeve 603 is rotatably installed between the feeding frame 3 and the support frame 4 through a support shaft and a support plate, and is located on the opposite side of the material blocking guide block 601. The material blocking plate 602 is fixedly connected to one side of the shaft sleeve 603, and is arranged in an inclined manner inside the support frame 4. The end of the material blocking plate 602 away from the shaft sleeve 603 abuts against the outer end face of the material blocking guide block 601. A transmission assembly 9 for driving the shaft sleeve 603 to rotate is arranged on the other side of the shaft sleeve 603.

[0033] In this embodiment, the construction waste from the material receiving cavity 503 freely falls on the inclined material guide surface of the material blocking guide block 601, avoiding the impact force of the falling waste from damaging the working elements inside the support frame 4. Under the combined action of the material blocking guide block 601 and the material blocking plate 602, the material blocking plate 602 can block the inside of the support frame 4, so that different spaces are formed above and below the feeding cylinder 501. Before the material blocking plate 602 is opened, the construction waste is stored in the space below the feeding cylinder 501, further realizing intermittent entry of the waste into the crushing mechanism 1, and the splashing waste will not splash into the inside of the feeding frame 3 when the crushing mechanism 1 is crushing the waste, thereby protecting the elements inside the feeding frame 3.

[0034] It needs to be further pointed out that, in Figure 5 、 Figure 6 、 Figure 7 The transmission assembly 9 arranged on the other side of the shaft sleeve 603 comprises a connecting plate 901, a transmission shaft 902, a vertical rod 903, a transmission seat 904 and a pull rod 905, one end of the connecting plate 901 is detachably connected to the bottom of the material blocking plate 602 through bolts, the other end of the connecting plate 901 is provided with an open slot 9011 and extends to the lower side of the platform 705, a through slot 7051 is arranged on the platform 705 corresponding to the open slot 9011, the vertical rod 903 is movably arranged through the through slot 7051, the transmission seat 904 is fixedly connected to the bottom of the vertical rod 903, and a limiting slot 9041 is arranged on the transmission seat 904, the transmission shaft 902 is arranged in the open slot 9041, and both ends of the transmission shaft 902 are respectively connected to the slot walls of the open slot 9041, and the middle part of the transmission shaft 902 is movably arranged in the limiting slot 9041, wherein the limiting slot 9041 is designed as a long slot, which can effectively prevent the transmission shaft 902 from appearing at a transmission dead point position in the limiting slot 9041; one end of the pull rod 905 is hingedly connected to the top of the vertical rod 903, and the other end of the pull rod 905 is hingedly connected to the bottom of the horizontal rod 706.

[0035] In the embodiment, when the piston rod of the cylinder 701 is stretched to drive the horizontal rod 706 to move to the direction of the feeding frame 3, the horizontal rod 706 drives the pull rod 905 to pull the vertical rod 903 to move upward, and the limiting slot 9041 of the transmission seat 904 at the bottom of the vertical rod 903 also drives the transmission shaft 902 to move upward, since the connecting plate 901 is connected to the material blocking plate 602, the material blocking plate 602 is rotated around the shaft sleeve 603 as the center, so that the end of the material blocking plate 602 gradually moves downward, and the space below the feeding cylinder 501 is in an open state, at this time, the construction waste can fall into the feeding port of the crushing mechanism 1 from between the material blocking plate 602 and the material blocking guide block 601.

[0036] The working principle of the utility model will be further described as follows:

[0037] First, the piston rod of the cylinder 701 extends and drives the cross rod 706 to move in the direction of the feeding frame 3, pushes the connecting rod 707 to move synchronously, the rack 703 drives the gear 702 to rotate under the pushing of the connecting rod 707, at this time, the feeding cylinder 501 rotates synchronously with the gear 702, the material receiving cavity 503 on the feeding cylinder 501 drives the internal construction waste to rotate, when the material receiving cavity 503 rotates to the upper side of the material blocking guide block 601, the construction waste falls freely on the inclined material guide surface of the material blocking guide block 601 under the action of gravity; at the same time, the cross rod 706 drives the pull rod 905 to pull the vertical rod 903 to move upward, the limiting groove 9041 on the transmission seat 904 fixedly connected with the bottom of the vertical rod 903 also drives the transmission shaft 902 to move upward, since the connecting plate 901 is connected with the material blocking plate 602, the material blocking plate 602 rotates around the shaft sleeve 603, so that the end of the material blocking plate 602 moves downward gradually, the space below the feeding cylinder 501 is in an open state, at this time, the construction waste can fall into the feeding port of the crushing mechanism 1 from the space between the material blocking plate 602 and the material blocking guide block 601. The utility model realizes the intermittent feeding of the construction waste, by controlling the extension and retraction speed and times of the piston rod of the cylinder 701, the feeding amount and feeding speed of the waste can be controlled well.
