The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It will be appreciated by those skilled in the art that in the present disclosure, the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. refer to an orientation or positional relationship based on that shown in the drawings, which is merely for convenience of description and to simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore the above terms should not be construed as limiting the present invention.

It will be understood that the terms "a" and "an" should be interpreted as referring to "at least one" or "one or more," i.e., in one embodiment, the number of elements may be one, while in another embodiment, the number of elements may be plural, and the term "a" should not be interpreted as limiting the number.

Referring to fig. 1 to 3, a garbage sorting apparatus for sorting mixed garbage according to a preferred embodiment of the present invention will be described in detail below. It is understood by those skilled in the art that the mixed waste is composed of light materials, flat materials, small granular materials, medium and heavy materials mixed. Wherein the light materials comprise plastics, broken paper scraps, leaves and the like; the small granular substances comprise small stones, gravel, broken glass and the like; flat materials include textiles, large wet plastic bags, and the like; the medium weight materials comprise hard plastics, melon peel, pop cans and the like; the weight includes stone and the like.

The waste sorting apparatus comprises a sorting bin 10 and a first sorting assembly 20.

The sorting bin 10 forms a sorting chamber 1001, the high end of the sorting bin 10 forms a feed inlet 1002 communicated with the sorting chamber 1001, wherein the low end of the sorting bin 10 forms a light material outlet 1003 and a mixed material outlet 1004, the sorting bin 10 forms an air inlet 1005 between the low end and the high end, and mixed garbage falls into the sorting chamber 1001 through the feed inlet 1002.

The first sorting unit 20 includes an air forming member 21, an air outlet of the air forming member 21 is communicated with the air inlet 1005, and a wind direction generated by the air forming member 21 is led to the sorting chamber 1001 and toward the light material outlet 1003, so as to perform first sorting on the mixed garbage, thereby separating light materials in the mixed garbage to the light material outlet 1003. It will be appreciated that the light materials in the mixed waste are light in weight, and the light materials in the mixed waste are blown to the light material outlet 1003 by wind under the action of the wind forming member 21, whereas the light material waste is heavy in weight, is less affected by the wind, and thus falls to the mixed material outlet 1004. That is, the horizontal distance between the position where the mixing and dispensing outlet 1004 is provided and the position where the air inlet 1005 is provided is smaller than the horizontal distance between the position where the light material outlet 1003 is provided and the position of the air inlet 1005. In this way, the light substances in the mixed garbage can be effectively separated.

In one embodiment, the wind forming member 21 is implemented as a centrifugal fan.

Preferably, the first sorting assembly 20 further includes at least one scattering member 22, where the scattering member 22 is mounted in the sorting chamber 1001, and the scattering member 22 is configured to scatter the mixed garbage falling into the sorting chamber 1001 from the feeding hole 1002, so as to uniformly scatter the clustered mixed garbage or the wrapped mixed garbage, thereby improving the quality of the first sorting of the wind forming member 21.

Preferably, the scattering member 22 is provided in plurality, and the scattering members are distributed in the sorting chamber 1001 in a staggered manner, and are disposed between the feeding port 1002 and the air inlet 1005, so as to reduce the falling speed of the mixed garbage and scatter the mixed garbage for a plurality of times, so as to improve the scattering quality and improve the first sorting quality of the wind forming member 21. As will be appreciated by those skilled in the art, the reduced speed of the mixed waste ensures that the light material in the mixed waste is blown to the light material outlet 1003 for a period of time, which effectively reduces the volume of the bin 10 while ensuring that the light material is sorted.

In one embodiment, the break-up member 22 is implemented as a baffled break-up plate. The mixed garbage naturally falls down to collide with the baffle scattering plate, and the clustered mixed garbage or the wrapped mixed garbage is scattered.

The second separating inlet 3103 is in communication with the mixing and separating outlet 1004, so that the mixed garbage after the first separation enters the sliding channel 3101 for the second separation. The flat-type substance outlet 3102 is formed at an end of the sliding main chamber 31 near the second sorting outlet 3104 and penetrates the bottom wall of the sliding passage 3101.

The inner wall of the sliding main bin 31 forming the sliding passage 3101 and contacting the mixed garbage entering from the second separating inlet 3103 forms a friction increasing surface for increasing friction between the inner wall of the sliding main bin 31 and the mixed garbage.

As will be appreciated by those skilled in the art, in the first sorted mixed refuse, the contact area between the different kinds of refuse and the bottom wall of the sliding channel 3101 is different, so that the friction force is different, resulting in different sliding speeds. That is, the contact area between the flat garbage and the bottom wall of the sliding channel 3101 is the largest, so that the friction force is the largest, and the sliding speed of the garbage is the smallest, so that the flat garbage is separated from the flat garbage outlet 3102 into the sliding main bin 31, and the contact area between the three-dimensional garbage and the bottom wall of the sliding channel 3101 is small, so that the speed is faster, and the garbage moves to the second separating outlet 3104 beyond the flat garbage outlet 3102.

Preferably, the second sorting unit 30 further includes a discharge branch portion 32, the discharge branch portion 32 is mounted at the lower end portion of the sliding main bin 31, the discharge branch portion 32 defines a discharge channel 3201 communicating with the flat material outlet 3102, the discharge branch portion 32 defines a collection port 3202 communicating with the discharge channel 3201, and the flat material enters the discharge channel 3201 through the flat material outlet 3102 and is collected through the collection port 3202. Preferably, the sliding main bin 31 is integrally formed with the discharge branch 32.

In one embodiment, the skid main bin 31 is integrally formed with the sorting bin 10. That is, the mixed feed outlet 1004 is also defined as the second feed inlet 3103.

Further, the waste sorting apparatus further comprises a feeding assembly 40.

The feeding assembly 40 includes a conveying member 41 and a first driving member 42, and the conveying member 41 is held at the feeding port 1002 to convey the mixed garbage from the feeding port 1002 to the sorting chamber 1001. The conveying member 41 is drivably connected to the first driving member 42, and the first driving member 42 is used for driving the conveying member 41 to convey.

In one embodiment, the first drive member 42 is implemented as a motor.

Referring to fig. 5-6, further, the waste sorting apparatus further includes a third sorting assembly 50.

It should be noted that the acute angle formed by the third sorting assembly 50 and the horizontal plane is smaller than the acute angle formed by the sliding main bin 31 and the horizontal plane, so that heavy matters and medium heavy matters in the mixed garbage after the first sorting and the second sorting are prevented from falling into the flat matters outlet 3102, and the difference between the acute angle formed by the third sorting assembly 50 and the horizontal plane and the acute angle formed by the sliding main bin 31 and the horizontal plane is set with a predetermined value.

The third sorting assembly 50 includes a skid body 51 and a governor 52. The sliding body 51 is mounted obliquely to an end of the sliding main chamber 31 near the second sorting outlet 3104. The sliding body 51 forms a moving channel 5101 communicating with the second sorting outlet 3104 and a third sorting outlet 5102 communicating with the moving channel 5101, the third sorting outlet 5102 penetrates through the bottom wall of the moving channel 5101, the extending direction of the moving channel 5101 forms a heavy matter outlet 5103,

the speed regulating member 52 is extended from the inner wall of the moving passage 5101 toward the lateral direction to form a speed feeding end 521.

Preferably, the speed governor 52 presents an arc shape.

It will be appreciated that the mixed waste after the first sorting and the second sorting falls down to the moving tunnel 5101 and is separated from the speed regulating member 521 after sliding on the surface of the speed regulating member 52 via the speed regulating member 521. The heavy materials in the mixed garbage are separated from the speed-giving end 521 due to large weight and large inertia, so that the heavy materials can be thrown far, and the garbage with lighter weight can be thrown closer. Heavy material can thus pass over the third sorting outlet 5102 and be thrown to the heavy material outlet 5103, while lighter weight waste falls into the third sorting outlet 5102. In this way, it is thus possible to separate heavy and light waste.

It should be noted that the sliding main chamber 31 is integrally formed with the sliding body 51.

It will be appreciated by those skilled in the art that the waste sorting apparatus may not be provided with the second sorting member 30, in which case the third sorting assembly 50 is mounted obliquely to an end of the mixing and sorting outlet 1004 of the sorting bin 10, and the end of the moving channel 5101 remote from the third sorting outlet 5102 communicates with the mixing and sorting outlet 1004.

Further, the waste sorting apparatus further comprises a fourth sorting assembly 60.

The fourth sorting module 60 includes a main body 61 and a material deflector 62, the main body 61 forms a mounting space 6102 communicating with the third sorting outlet 5102, the main body 61 has a medium heavy material outlet 6101 communicating with the mounting space 6102, and the material deflector 62 is rotatably mounted to the mounting space 6102 and divides the mounting space 6102 into a collecting region and a sieving region. The stirring piece 62 is used for stirring the mixed garbage and driving the mixed garbage from the collecting area to the sieving area. The collection region is located adjacent to the screening region and is in communication with the third sort outlet 5102, and the medium-heavy material outlet 6101 is formed at a side of the screening region remote from the collection region. The deflector 62 defines a high end and a low end, the high end of the deflector 62 rotating from the collection zone toward the screening zone as the high end of the deflector 62 moves toward the low end of the deflector 62.

The collection area is used for collecting the mixed garbage entering from the third sorting outlet 5102, and the mixed garbage in the collection area moves to the sieving area under the rotation of the material shifting piece 62. The part of the sieving area corresponding to the main body 61 forms a plurality of sieve holes 6103 for sorting small granular materials in the mixed garbage in the sieving area, while medium heavy materials are larger and cannot pass through the sieve holes 6103 and are pushed to the medium heavy material outlet 6101 by the material stirring piece 62, so that fourth sorting is realized.

Preferably, the sliding body 51 is integrally formed with the main body 61.

Referring to fig. 7, the fourth sorting assembly 60 preferably includes a second driving member 63, the material stirring member 62 is drivably connected to the second driving member 63, and the second driving member 63 is configured to drive the material stirring member 62 to rotate.

And when the mixed garbage is subjected to third sorting, the parabolic stroke of heavy matters falls to the fourth sorting inlet, and the speed regulating piece 52 enables the heavy matters to obtain acceleration, and the heavy matters break the hairbrush under high-speed movement and jump out of the heavy matters outlet 5103.

The invention also provides a working method of the garbage classification equipment, wherein the working method of the garbage classification equipment comprises the following steps:

(A) The wind forming piece 21 acts on the mixed garbage in the sorting cavity 1001 to separate light matters from the light matter outlet 1003, and the rest mixed garbage enters the mixed garbage outlet 1004;

(B) Mixed garbage enters the sliding channel 3101, and according to the contact area of different kinds of garbage on the bottom wall of the sliding channel 3101, the friction force is different, so that the sliding speeds are different, therefore, flat garbage can be separated from the sliding main bin 31 through the flat garbage outlet 3102 and collected by the discharging branch part 32, and the three-dimensional garbage has higher speed and can move to the second separating outlet 3104 through the flat garbage outlet 3102;

10. The working method of the garbage classification equipment is characterized by comprising the following steps of:

(A) The wind forming piece acts on the mixed garbage in the sorting cavity to separate light matters from the light matter outlet, and the rest mixed garbage enters the mixed material outlet;

(B) The mixed garbage enters the sliding channel, and the sliding speeds are different according to different contact areas of different types of garbage and the bottom wall of the sliding channel, so that the flat garbage can be separated from the sliding main bin through the flat material outlet and collected by the discharging branch part, and the three-dimensional garbage is small in contact with the inner wall of the sliding channel, small in friction, high in speed and capable of moving to the second sorting outlet beyond the flat material outlet;

(C) The mixed garbage enters the moving channel, the mixed garbage falls to the speed regulating piece in the moving channel, acceleration is obtained in the sliding process of the mixed garbage, so that after the motion track is converted into a parabola, heavy matters can pass through the third sorting outlet and be thrown to the heavy matter outlet, and the garbage with lighter weight falls to the third sorting outlet;

(D) The mixed garbage is screened in the screening area, small granular matters pass through the screen holes, and medium heavy matters are moved out of the medium heavy matter outlet under the driving of the stirring piece.
