Technical Field

The invention relates to the field of garbage compression equipment, in particular to a push plate device with garbage auxiliary crushing function.

Background

At present, the domestic garbage compression type compression mechanism is a working mode that garbage is directly compressed by pressing the plane of a push plate against a surface. Because rubbish is disordered, the rubbish contains a large amount of little spaces, is full of air and moisture in the little space, and rubbish compression is exactly the air and the moisture in the displacement space in essence. The garbage contains a large amount of plastic bags, and because the plastic bags have strong toughness, a large amount of air and water enclosed in the plastic belts are difficult to crush and discharge by the surface pressure of the plane of the push plate. Meanwhile, the garbage also contains a large number of small wood rods or hard rods such as branches, the hard rods can be used for constructing space frame structures in an unordered mode, and the space frame structures prevent the garbage from being compressed, so that a large number of gaps exist inside the garbage. The garbage compaction rate is reduced. In conclusion, the compression effect is greatly reduced due to the reasons, the garbage rebounding phenomenon is serious, and the compression efficiency is reduced due to the garbage rebounding phenomenon; the loading capacity of the garbage can does not reach the designed loading capacity, so the transport capacity of the transport vehicle is wasted, and the transport cost is increased.

The push plate oil cylinder 1 and each auxiliary crushing oil cylinder 2 are controlled to act by a hydraulic system respectively; the hydraulic system comprises a three-position four-way O-shaped electromagnetic directional valve 6, a hydraulic control oil path selection valve 7, a first sequence valve 8 and a second sequence valve 9;

a port P of the three-position four-way O-shaped electromagnetic directional valve 6 is connected to a pressure oil path, the pressure oil path supplies pressure oil source for the work of a hydraulic system, a port T of the three-position four-way O-shaped electromagnetic directional valve 6 is connected with an oil return path, a port A of the three-position four-way O-shaped electromagnetic directional valve 6 is connected to a port P1 of the hydraulic control oil path selecting valve 7 through an oil path, and a port B of the three-position four-way O-shaped electromagnetic directional valve 6 is connected to a port P2 of the hydraulic control oil path selecting valve;

a port 1 of the hydraulic control oil path selection valve 7 is connected to a large cavity of the push plate oil cylinder 1 through an oil path, a port 2 of the hydraulic control oil path selection valve 7 is connected to a small cavity of the push plate oil cylinder 1 through an oil path, a port 3 of the hydraulic control oil path selection valve 7 is connected to a large cavity of each auxiliary crushing oil cylinder 2 through an oil path, and a port 4 of the hydraulic control oil path selection valve 7 is connected to a small cavity of each auxiliary crushing oil cylinder 2 through an oil path;

an oil inlet of the first sequence valve 8 is connected to an oil path between the port 2 of the hydraulic control oil path selection valve 7 and the small cavity of the push plate oil cylinder 1 in parallel through an oil path, and an oil outlet of the first sequence valve 8 is connected to a left control oil port of the hydraulic control oil path selection valve 7 through an oil path;

an oil inlet of the second sequence valve 9 is connected to an oil path between the port 3 of the hydraulic control oil path selection valve 7 and the large cavity of the auxiliary crushing oil cylinder 2 in parallel through an oil path, and an oil outlet of the second sequence valve 9 is connected to a right control oil port of the hydraulic control oil path selection valve 7 through an oil path.

When the hydraulic control oil way selector valve 7 is in the left working position, the port P1 is communicated with the port 3, the port P2 is communicated with the port 4, and the port 1 and the port 2 are closed; when the pilot-controlled oil path selector valve 7 is in the right working position, the port P1 is communicated with the port 1, the port P2 is communicated with the port 2, and the ports 3 and 4 are closed.

The hydraulic system further comprises a first orifice 5 and a second orifice 10; one end of the first damping hole 5 is connected to an oil path between an oil outlet of the first sequence valve 8 and a left control oil port of the hydraulic control oil path selection valve 7 in parallel through an oil path, and the other end of the first damping hole 5 is connected to an oil return path through an oil path; one end of the second damping hole 10 is connected to an oil path between an oil outlet of the second sequence valve 9 and a right control oil port of the hydraulic control oil path selection valve 7 in parallel through an oil path, and the other end of the second damping hole 10 is connected to an oil return path through an oil path.

The working principle of the invention is as follows: when the electromagnet at the left end of the three-position four-way O-shaped electromagnetic reversing valve 6 is electrified, the hydraulic control oil path selection valve 7 is at the left working position, pressure oil provided by the pressure oil path flows out from the port A of the three-position four-way O-shaped electromagnetic reversing valve 6, enters the port P1 of the hydraulic control oil path selection valve 7, flows out from the port 3 of the hydraulic control oil path selection valve 7, enters the large cavity of the auxiliary crushing oil cylinder 2, and accordingly the auxiliary crushing rod 3 is pushed to stretch out. When the auxiliary breaker bar 3 is extended in place, the pressure of the pressurized oil rises above the set value of the second sequence valve 9, and the second sequence valve 9 opens. The pressure oil enters the right control oil port of the hydraulic control oil path selection valve 7 through the second sequence valve 9 so as to push the valve core of the hydraulic control oil path selection valve 7 to move leftwards, and the hydraulic control oil path selection valve 7 becomes a right working position. The first damping hole 5 is communicated with the oil return path, so that a left control cavity of the hydraulic control oil path selection valve 7 is in a pressure relief state, and the valve core of the hydraulic control oil path selection valve 7 is ensured to move stably and change direction correctly. The pressure oil goes out from the port 1 of the hydraulic control oil path selection valve 7 and enters the large cavity of the push plate oil cylinder 1, so that the push plate 4 is pushed to push compressed garbage. Because the auxiliary crushing rod 3 is positioned at the position extending out of the surface of the pushing plate, the auxiliary crushing rod 3 contacts with the garbage firstly, and because the auxiliary crushing rod 3 and the garbage can be regarded as point contact, bag-shaped objects such as plastic bags and the like can be punctured easily, and a space frame structure built by the hard rods in the garbage randomly can be punctured easily. The push plate 4 is pushed out continuously, the surface of the push plate contacts with the garbage, so that the garbage is extruded, and air and moisture in the garbage are discharged through the channel punctured by the auxiliary crushing rod 3. Because 3 mouths and 4 mouths are in a closed state, the auxiliary crushing oil cylinder 2 can not be withdrawn under the action of the garbage reaction force in the compression process, and the crushing force of the auxiliary crushing rod 3 is ensured. Therefore, the method can smoothly discharge the air and the moisture in the garbage by using smaller thrust, and effectively improve the garbage compaction degree. Meanwhile, the garbage resilience can be reduced, the compression efficiency is improved, and the garbage disposal operation cost is saved.

When the electromagnet at the right end of the three-position four-way O-shaped electromagnetic reversing valve 6 is electrified, the hydraulic control oil path selecting valve 7 is at the right working position, pressure oil provided by the pressure oil path flows out from the port B of the three-position four-way O-shaped electromagnetic reversing valve 6, enters the port P2 of the hydraulic control oil path selecting valve 7, flows out from the port 2 of the hydraulic control oil path selecting valve 7, enters the small cavity of the push plate oil cylinder 1, and then pushes the push plate 4 to retract. When the push plate 4 is retracted to the proper position, the pressure of the pressurized oil rises above the set value of the first sequence valve 8, and the first sequence valve 8 opens. The pressure oil enters the left control oil port of the pilot-controlled oil path selection valve 7 through the first sequence valve 8 so as to push the valve core of the pilot-controlled oil path selection valve 7 to move rightwards, and the pilot-controlled oil path selection valve 7 becomes a left working position. The second damping hole 10 is communicated with the oil return path, so that the right control cavity of the hydraulic control oil path selection valve 7 is in a pressure relief state, and the valve core of the hydraulic control oil path selection valve 7 is ensured to move stably and change direction correctly. The pressure oil flows out of the port 4 of the hydraulic control oil path selection valve 7 and enters the small cavity of the auxiliary crushing oil cylinder 2, so that the auxiliary crushing rod 3 is pushed to be retracted, and a small amount of garbage hung on the auxiliary crushing rod 3 is removed. The situation that the more the garbage hung on the auxiliary crushing rod 3 is accumulated, the auxiliary crushing function is disabled, the garbage compaction rate is reduced, the garbage resilience is increased, and the garbage compression efficiency is reduced is avoided.
