Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present invention, the following detailed description of the present invention with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present invention.
As shown in fig. 1-5, the specific structure of the invention is as follows: the municipal solid waste separator comprises a shell, wherein a feed inlet 101 is arranged above the shell 1, a heavy waste outlet 102 and a light waste outlet 103 are arranged below the shell, and the feed inlet 101 is arranged above the heavy waste outlet 102; the two sides of the shell 1 are provided with shell sliding grooves 104, the shell sliding grooves 104 are provided with sliding plates 2 capable of sliding horizontally, the sliding plates 2 are provided with a driving shaft 3 and a driven shaft 4 which can rotate in a horizontal plane in parallel, the driving shaft 3 and the driven shaft 4 are connected through gear transmission and have opposite rotation directions, the circumference of the driving shaft 3 is provided with a plurality of chip grabbing needles 31 in a staggered manner, and the circumference of the driven shaft 4 is provided with a plurality of chip unloading needles 41 in a staggered manner; the side of the shell 1 is provided with a motor 5 in transmission connection with the driving shaft 3, the shell 1 is provided with a connecting rod 6, one end of the connecting rod 6 is hinged with the shell 1, and the other end of the connecting rod is eccentrically hinged with the driven shaft 4.
Preferably, the sliding plate 2 is provided with a rotatable roller 7, the roller 7 is eccentrically sleeved outside the driving shaft 3, and the outer circumference of the roller 7 is provided with a roller through hole 701 matched with the chip grabbing needle 31. The rollers 7 rotate together through the chip grabbing needles 31, but rotate around the respective axes, and the chip grabbing needles 31 continuously penetrate into and withdraw from the roller through holes 701 along with the rotation, so that the purpose is to ensure that when the chip grabbing needles 31 withdraw from the roller through holes 701, the rollers 7 bring the garbage at the root parts of the chip grabbing needles 31 out, so that the chip unloading needles 41 can conveniently grab the garbage, and in addition, the rollers 7 realize reciprocating extrusion with the inner side walls of the shell 1 along with the horizontal reciprocating motion of the sliding plates 2, so that larger garbage can be crushed for the second time, and the garbage can be thoroughly sorted.
Preferably, the driving shaft 3 is provided with a chip grabbing needle base 311, a driving shaft spring 312 is arranged in the chip grabbing needle base 311, and the chip grabbing needle 31 is connected with the chip grabbing needle base 311 through the driving shaft spring 312. When the chip grabbing needle 31 pierces harder substances, the driving shaft spring 312 can effectively play a role in buffering, and meanwhile the chip grabbing needle 31 is effectively avoided, so that damage to the chip grabbing needle is prevented.
Preferably, the driven shaft 4 is provided with a chip discharging needle base 411, a driven shaft spring 412 is arranged in the chip discharging needle base 411, and the chip discharging needle 41 is connected with the chip discharging needle base 411 through the driven shaft spring 412. When the chip discharging needle 41 pierces harder substances, the driven shaft spring 412 can effectively play a role of buffering, and meanwhile, the chip discharging needle 41 is effectively avoided, so that the chip discharging needle is prevented from being damaged.
Preferably, the head of the shirttail needle 41 is provided with a shirttail needle barb 401. The crumb rubber discharging needle barb 401 is effective to hook the refuse which is stuck on the crumb rubber grabbing needle 31, thereby discharging it from the light refuse outlet 103.
Preferably, the upper surface of the inner wall of the housing 1 is roughened. When the roller 7 and the inner wall of the shell 1 move relatively, the friction force is utilized to tear some long garbage, so that the long garbage is prevented from adhering to the roller 7.
Preferably, comb grooves 105 (mesh-like) are provided between the inner wall of the housing 1 and the chip-catching needle 31. On the one hand, when the scrap grabbing needle 31 is used for inserting scraps of paper or plastic in a left-right reciprocating mode, the scrap grabbing needle 31 passes through the holes of the comb-type grooves 105, the scraps of paper or plastic are left on the rod portion of the scrap grabbing needle 31, and on the other hand, fine garbage (such as mud, sand and the like) is convenient to directly filter out from the comb-type grooves 105.
When the garbage is specifically used, after passing through the feed inlet, the motor drives the driving shaft to move, the scrap grabbing needle pierces light garbage (such as paper scraps, plastic bags and the like) under the action of reciprocating movement of the sliding plate (the connecting rod is eccentrically connected with the driven shaft to form a crank connecting rod mechanism), the light garbage is rotationally brought to the upper part of the light garbage discharge port, and at the moment, the scrap unloading needle on the driven shaft is intersected with the scrap grabbing needle to actively grab garbage and discharge the garbage from the active scrap grabbing needle, so that the light garbage is discharged, the heavy garbage moves downwards along the inner wall of the shell and is discharged from the heavy garbage outlet, the quick separation of the light garbage and the heavy garbage is realized, the secondary recovery treatment of the light garbage and the plastic bags is convenient, and the separator occupies small space and is low in cost.
