DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] like Figure 1 and Figure 2 As shown, a slag grab with a crushing function includes a support frame 101 for connecting to the outside, a support frame 103 is rotatably installed on the support frame 101 for supporting, a flip motor is also fixedly installed on the support frame 101, and the output shaft of the flip motor is fixedly connected to the support frame 103. After starting the flip motor, the support frame 103 can be rotated 180 degrees, and a filter plate 102 is fixedly installed on one end of the support frame 103 close to the support frame 101, and a plurality of sieve holes are arranged on the filter plate 102. After the support frame 103 is flipped, only the garbage that can pass through the sieve holes on the filter plate 102 can fall out of the device, and two compensation plates 2 are fixedly installed on the side of the support frame 103 away from the filter plate 102. 08. The compensation plate 208 is symmetrically arranged on the bracket frame 103. The shape of the compensation plate 208 is semicircular. One side of the bracket frame 103 on which the compensation plate 208 is arranged is also rotatably installed with two lower opening and closing bins 207. The lower opening and closing bins 207 are symmetrically arranged on the bracket frame 103 to clamp garbage. The compensation plate 208 contacts the lower opening and closing bins 207. The compensation plate 208 is used to fill the dead corner of the lower opening and closing bins 207, so as to prevent the lower opening and closing bins 207 from getting stuck when rotating. A plurality of opening and closing cylinders 104 are rotatably installed outside the compensation plate 208. The moving end of the opening and closing cylinder 104 is rotatably connected to the outer wall of the lower opening and closing bin 207. The function of the opening and closing cylinder 104 is to drive the lower opening and closing bin 207 to perform opening and closing movements.

[0019] like Figures 2 to 5As shown, the lower opening and closing bin 207, the support frame 103, and the filter plate 102 constitute a crushing chamber, and a driving cylinder 201 is arranged in the crushing chamber, and the driving cylinder 201 is fixedly connected to the inner wall of the support frame 103, and the driving cylinder 201 is arranged on the side of the support frame 103 close to the filter plate 102, and a main rotating rod 206 is rotatably installed on the moving end of the driving cylinder 201, and a plurality of swing arms 202 are also rotatably installed on the moving end of the driving cylinder 201, and a first torsion spring is further arranged between the plurality of swing arms 202, and the two ends of the first torsion spring are respectively arranged on two different swing arms 202, and the swing arms 202 are away from the main rotating rod. A limiting wheel 209 is rotatably installed at one end of the rod 206, and a secondary rotating rod 203 is also rotatably installed at the end of the swing arm 202 away from the main rotating rod 206. The secondary rotating rod 203 is symmetrically arranged in the crushing chamber, and a plurality of crushing teeth are arranged on the secondary rotating rod 203 and the main rotating rod 206. The crushing teeth on the secondary rotating rod 203 and the main rotating rod 206 are both arranged for crushing the garbage in the crushing chamber. A driving device is arranged in the secondary rotating rod 203 and the main rotating rod 206 to drive the secondary rotating rod 203 and the main rotating rod 206 to rotate, so that the secondary rotating rod 203 and the main rotating rod 206 can perform crushing work.

[0020] like Figure 4 and Figure 5 As shown, an inner groove is provided on the inner wall of one side of the compensation plate 208 of the bracket frame 103, and a plurality of track grooves 204 are also slidably installed on the inner side of the compensation plate 208 of the bracket frame 103, and an inner card groove is provided on the track groove 204. The track groove 204 is symmetrically arranged on the bracket frame 103, and the track groove 204 is arranged on the inner groove. A compensation spring 205 is fixedly installed on the track groove 204, and the other end of the compensation spring 205 is fixedly installed on the bracket frame 103. The compensation spring 205 is completely installed in the inner groove, and the track groove 204 contacts with the limiting wheel 209 on the swing arm 202. The limiting wheel 209 is arranged in the inner card groove on the track groove 204, and the limiting wheel 209 can only move in the inner card groove.

[0021] When in use, the device needs to be placed on a crane through the support frame 101, and then the device is moved by the crane in the incineration plant or transfer yard, and then the opening and closing cylinder 104 drives the lower opening and closing bin 207 to open and close, allowing the garbage to enter the crushing chamber. In the crushing chamber, the auxiliary rotating rod 203 and the main rotating rod 206 can be selected not to start, so that the device is a normal rotating grab bucket.

[0022] After starting the secondary rotating rod 203 and the main rotating rod 206, the secondary rotating rod 203 and the main rotating rod 206 can be driven by the teeth on the surface to collide with the garbage in the crushing chamber, so as to perform the garbage crushing work. At this time, the driving cylinder 201 is started to drive the driving cylinder 201 to drive the main rotating rod 206 to move away from the filter plate 102. When the main rotating rod 206 moves, the swing arm 202 will also pull the secondary rotating rod 203 to move away from the filter plate 102, and the track slot 204 will also move accordingly during this period, and the track slot 204 and the compensation spring 205 are in a state of being moved away from the filter plate 102. The purpose of the setting is to compensate for the displacement of the auxiliary rotating rod 203 to prevent the auxiliary rotating rod 203 from getting stuck during the movement, and at the same time to limit the moving trajectory of the auxiliary rotating rod 203. The auxiliary rotating rod 203 and the main rotating rod 206 move in the crushing chamber to completely crush the garbage in the crushing chamber, and the function of the trajectory slide groove 204 is to prevent the auxiliary rotating rod 203 from contacting the filter plate 102 and the inner wall of the lower opening and closing bin 207, thereby damaging the crushing teeth. After crushing, the lower opening and closing bin 207 can be driven to rotate by 14 to allow the garbage in the crushing chamber to fall out of the device from the lower opening and closing bin 207.

[0023] If the crushing degree is required, the bracket frame 103 can be turned 180 degrees by turning the motor, so that the crushing degree is greater than 100 degrees. Figure 2 The filter plate 102 is at the bottom and the lower opening and closing bin 207 is at the top, so that the garbage can only fall out of the device after passing through the drying mesh holes on the filter plate 102, and the auxiliary rotating rod 203 and the main rotating rod 206 will also continue to crush the garbage that does not pass through the mesh holes.

[0024] When the device needs to crush some garbage that cannot be accommodated in the crushing chamber, or when it needs to process a pile of garbage that does not need to be transported but only needs to be crushed, the opening and closing cylinder 104 can be started to rotate the lower opening and closing bin 207 at least sixty degrees, and then the lower opening and closing bin 207 can be opened. Then the driving cylinder 201 can be started to drive the main rotating rod 206 to move away from the filter plate 102, and the driving cylinder 201 must drive the main rotating rod 206 to the extreme position before it can stop. The purpose of this is to allow the main rotating rod 206 and the auxiliary rotating rod 203 to leave the crushing chamber as far as possible and get as close to the garbage outside the crushing chamber as possible. In this way, the auxiliary rotating rod 203 and the main rotating rod 206 can be started again to crush the garbage outside the crushing chamber.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
