Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples or figures are illustrative of the present invention and are not intended to limit the scope of the present invention.

The tank body and the suction device on the garbage truck can be realized by adopting the prior art; the tank body needs certain sealing performance to ensure that the kitchen waste cannot flow out; the suction device can ensure that sufficient negative pressure is generated in the hose to draw out the garbage in the garbage can.

As shown in fig. 1 and 2, the garbage can comprises a garbage can body 1, a garbage cover 4, a buckle 5 and a travelling mechanism 11, wherein as shown in fig. 5, the travelling mechanism 11 is installed at the bottom of the garbage can body 1, the garbage cover 4 is installed at the upper end of the garbage can body 1 in a swinging manner, and as shown in fig. 2, the buckle 5 is installed between the garbage cover 4 and the garbage can body 1; the method is characterized in that: as shown in fig. 3, a suction module 2 is mounted on the dustbin body 1, and as shown in fig. 7, the suction module 2 is composed of a suction channel 6 and a cover plate 15; as shown in fig. 3, the suction channel 6 is fixedly installed on the dustbin body 1, the lower end of the suction channel 6 is located in the dustbin body 1, and the upper end of the suction channel 6 is located outside the dustbin body 1; as shown in fig. 4 and 8, the cover plate 15 is swingably mounted on the upper end of the suction passage 6; a clamping block 16 which has a limiting effect on the cover plate 15 is arranged at the upper end of the suction channel 6.

The buckle 5 is used for locking the garbage cover 4 and the garbage can body 1, so that the sealing performance of the garbage can body 1 is ensured; the buckle 5 in the invention adopts the prior art.

According to the invention, the cover plate 15 has a cover sealing effect on the upper end of the suction channel 6, when the garbage bin is placed on the ground for collecting garbage, the cover plate 15 is in a closed state, and the limit block 29 limits the cover plate 15.

As shown in fig. 5, a partition plate 12 is fixedly mounted on the lower side of the interior of the dustbin body 1, the partition plate 12 is composed of an inclined plate 45 and a vertical plate 46, one end of the inclined plate 45 is fixedly mounted on the front wall surface of the interior of the dustbin body 1, the upper end of the vertical plate 46 is fixedly mounted on the other end of the inclined plate 45, and the lower end of the vertical plate 46 is fixedly mounted on the inner bottom surface of the dustbin body 1; the vertical plate 46, two side surfaces in the dustbin body 1 and the rear wall surface of the dustbin body 1 form a sliding groove 13; as shown in fig. 4 and 6, the sliding plate 7 is slidably mounted in the sliding groove 13, and the return spring 8 is mounted between the lower end of the sliding plate 7 and the bottom surface of the sliding groove 13; the sliding plates 7 are distributed obliquely, and the sliding plates 7 are parallel to the inclined plate 45.

When the garbage stored in the garbage can body 1 is sucked, the garbage in the garbage can body 1 flows downwards along the inclined plate 45 under the action of suction force, enters the upper side of the sliding plate 7 and is sucked out through the suction channel 6. In the process of suction, along with the gradual reduction of the garbage in the garbage can body 1, the downward pressure borne by the sliding plate 7 is also gradually reduced, and the sliding plate 7 can gradually move upwards under the action of the return spring 8.

As shown in fig. 9, the suction channel 6 is formed by three side plates 47, a U-shaped plate formed by the three side plates 47 is fixedly installed on the rear wall surface of the dustbin body 1, and a channel is formed by the three side plates 47 and the rear wall surface of the dustbin body 1; as shown in fig. 8 and 10, the lower end surfaces of two symmetrical side plates 47 of the three side plates 47 are obliquely distributed and flush with the upper end surface of the inclined plate 45 on the partition plate 12, and two symmetrical side plates 47 are respectively provided with a swinging plate 18 in a swinging manner, as shown in fig. 8, the lower end of the other side plate 47 of the three side plates 47 is provided with a swinging plate 19 in a swinging manner, the swinging plate 19 is matched with the two swinging plates 18, and the matching part of the swinging plate 19 and the two swinging plates 18 is in close contact.

When the sliding plate 7 is not in contact with the suction channel 6, the plane formed by the swinging plate 19 and the lower end surfaces of the two swinging plates 18 is parallel to the garbage cover 4; the lower end surfaces of the two swing plates 18 and 19 are provided with bulges which are uniformly distributed and have the height of 2-5 mm; the height is such as to ensure that, towards the end of the suction, the sliding plate 7 exerts an upward pressure on the oscillating plate 19 and on the two oscillating plates 18, and the projections ensure the clearance between the sliding plate and the oscillating plates 19 and 18, ensuring the suction capacity of the residual fluid waste. If there is no protrusion, the garbage can not enter the suction channel 6, if the protrusion is too large, the residual fluid garbage can not surround the protrusion to form a gap because the residual fluid garbage is less, and the inside of the relatively large suction channel 6 can not generate enough negative pressure because of sucking a large amount of air, so that the residual fluid garbage can not be easily pumped away.

The lower end surfaces of the two symmetrical side plates 47 designed in the invention are flush with the upper end surface of the upper inclined plate 45 of the partition plate 12, so that when the sliding plate 7 moves upwards to be in contact with the upper end surface of the upper inclined plate 45 of the partition plate 12, a gap is formed between the upper end surface of the sliding plate 7 and the lower end surfaces of the two symmetrically distributed side plates 47 under the action of the protrusions, and the suction capacity of residual fluid garbage is ensured.

When the garbage bin has garbage, the sliding plate 7 is pressed to the lowest side, the swinging plate 18 and the swinging plate 19 do not swing, the lower ends of the swinging plate 18 and the swinging plate 19 are positioned at the lower side of the lower end of the upper inclined plate 45 of the partition plate 12, a certain gap is formed between the lower ends of the swinging plate 18 and the swinging plate 19 and the pressed sliding plate 7, and the size of the gap can ensure that the suction channel 6 has high suction efficiency.

According to the invention, as the garbage on the upper side of the sliding plate 7 is gradually reduced, the sliding plate 7 can slowly slide upwards under the action of the return spring 8, and in the sliding process of the sliding plate 7, the gaps among the sliding plate 7, the swinging plate 18 and the lower end of the swinging plate 19 are gradually reduced so as to adapt to the reduction of the garbage and ensure that the garbage can be smoothly sucked away when the garbage is little. The invention starts to reduce the gap at the inlet of the suction channel 6 only when the garbage is basically pumped out quickly, and further reduces the inlet of the suction channel 6 by pressing the swinging plate 19 and the swinging plate 18 through the sliding plate 7 after the gap is small, the design can not influence the suction of large-particle garbage in the residual fluid garbage on the premise of ensuring the suction capability of the fluid garbage in a small amount of garbage, because the fluid quantity of the residual fluid garbage is very small when the gap starts to reduce and the inlet of the suction channel 6 starts to reduce, and the residual fluid garbage can not be sucked into the suction channel 6 with the large-particle garbage, so the invention increases the suction of the residual fluid garbage by designing the condition that the change of the gap and the inlet is not changed relative to the change of the gap and the inlet.

When the garbage is collected, a connecting pipe 36 is connected out of the collecting vehicle through a hose, an upper tightening sleeve 38 is rotatably mounted on the connecting pipe 36, one end of the connecting pipe 36 is aligned with the upper end of the suction channel 6 when the garbage is collected, then the connecting pipe 36 is fixed with the upper end of the suction channel 6 through the upper tightening sleeve 38, and the connecting pipe 36 is tightly pressed on the suction channel 6 through the upper tightening sleeve 38; after the connecting pipe 36 is tightly contacted with the upper end of the suction channel 6, the clamping block 16 arranged on the suction channel 6 is triggered by the connecting pipe 36 to release the limit of the cover plate 15, a suction device is arranged on the collection vehicle, and the suction device sucks the garbage in the garbage can into a tank body of the garbage vehicle through a hose.

The end face of the oscillating plate 18 has a clearance with the limit plate 17, and the clearance ensures that the oscillating plate 18 does not interfere with the limit plate 17 during oscillation.

The specific working process is as follows: when the recycling equipment designed by the invention is used and kitchen waste in the garbage can is collected, the connecting pipe 36 carried on the garbage truck is firstly pulled out, then one end of the connecting pipe 36 is aligned with the upper end of the suction channel 6, and the accuracy of alignment at each time can be ensured by designing alignment marks at the connecting pipe 36 and the suction channel 6; in the fixing process, after the connecting pipe 36 is in contact with the upper end surface of the circular opening 14, the connecting pipe 36 will press the trigger plate 20, so that the trigger plate 20 moves downwards, the trigger plate 20 moves downwards to press the fixture block 16 through the first inclined surface 34 on the fixture block 16, so that the fixture block 16 slides towards one end provided with the limiting spring 33, the fixture block 16 is separated from the clamping groove 31 formed in the limiting block 29 on the cover plate 15, and the fixture block 16 loses the limiting on the cover plate 15.

Then, the suction pump is turned on to suck, the cover plate 15 after limiting is opened upwards under the action of suction force, and after the cover plate is opened to be in a vertical state, the cover plate 15 is adsorbed by the magnetic adsorption block 37 and is tightly attached to the side surface of the avoiding groove 43 formed in the connecting pipe 36; the garbage in the garbage can slides downwards along the inclined plate 45 under the action of suction force, enters the upper side of the sliding plate 7 and is sucked out through the suction channel 6. In the process of suction, along with the gradual reduction of the garbage in the garbage can body 1, the downward pressure borne by the sliding plate 7 is also gradually reduced, and the sliding plate 7 can gradually move upwards under the action of the return spring 8; in the process of moving the sliding plate 7 upwards, after the upper side surface of the sliding plate 7 is contacted with the two swinging plates 18 and the swinging plate 19, the sliding plate 7 presses the two swinging plates 18 to swing upwards, and meanwhile, the sliding plate 7 presses the swinging plate 19 to swing towards the inner side of the suction channel 6; and in the process of extrusion swing, gaps are generated between the sliding plate and the swing plates 19 and 18 due to the protrusions, so that the suction capacity of residual fluid garbage is ensured.

After the suction is finished, the distance between the magnetic suction block and the cover plate 15 is increased by pulling the pull rod 39, after a certain distance is reached, the cover plate 15 swings downwards under the action of the second volute spring 51, in the swinging-down process, after the clamping groove 31 on the upper limiting block 29 of the cover plate 15 is matched, the tightening sleeve 38 is loosened, the connecting pipe 36 is taken up, at the moment, the clamping block 16 slides towards one side far away from the limiting spring 33 under the action of the limiting spring 33, the clamping block is matched with the clamping groove 31 to limit the cover plate 15, and the cover plate 15 is closed; the connecting tube 36 is retracted.
