Description

DETAILED DESCRIPTION OF THE INVENTION The purpose of the present invention is to perform process control to match the amount of waste discharged by a waste disposal device that stores and discharges bulky waste to the loading and processing capacity of different models of waste collection vehicles. It is something to do.

Conventionally, the garbage loading processing capacity of garbage collection vehicles differs depending on the model, and when a garbage disposal device and a garbage collection vehicle work together to load garbage, each time a garbage collection vehicle with a different capacity arrives,
It is necessary to adjust the discharge speed of the garbage discharge mechanism, and in reality, it takes time and is difficult to adjust, and if the amount of garbage discharged is less than the garbage loading processing capacity,
If the garbage loading time becomes long and the amount of garbage discharged is large, there is a risk that it will overflow from the hopper of the collection vehicle, so it is necessary to make adjustments to the garbage collection vehicle with an appropriate processing device that stores and discharges the garbage. There was a need for an improved device that could continuously load garbage in conjunction with the system.

The present invention answers that need.

To explain the embodiment of the present invention in detail with reference to the attached drawings, a garbage compacting device A is provided with a pushing plate 3 that moves forward and backward by a cylinder 4 in a compactor main body 1 having a hopper 2, and openings are formed in the front and rear. A garbage storage chamber 7 equipped with opening/closing doors 5 and 8 operated by cylinder mechanisms 6 and 9, and a garbage crushing blade 11, a stirring blade 12, and a discharge chamber arranged vertically on the inner circumferential surface of the rotary drum 10. Garbage is loaded by connecting the garbage receiving part of the garbage collection vehicle to the garbage discharge port 14 of the garbage processing device, which is composed of a garbage crushing device B having a garbage crushing device B with a garbage disposal blade 13 attached and a garbage discharge port 14 opened at its front end. After the amount of garbage put into the hopper 2 of the garbage compression device A is detected by the level detector 15, the pushing plate 3 is moved forward to compress the garbage between it and the opening/closing door 5, and then the garbage is compressed between the opening and closing door 5. Pull up the door 5 and push the compressed garbage with the push plate 3 to a position inside the storage chamber 7. Repeat this until the storage chamber 7 is full of compressed garbage, then pull up both opening/closing doors 5 and 8 and push it further. While moving the plate 3 forward at a slow speed and feeding it from the storage chamber into the rotary drum 10 of the compressed trash crushing device B, the trash that has been compressed and solidified by the rotation of the rotary drum 10 is crushed with the crushing blade 11.
Next, the dust is loosened by the stirring blade 12 and then discharged from the discharge port 14 of the crushing device by the discharge blade 13. The garbage is transferred to the connected garbage collection vehicle and loaded therein. For this loading, the amount of garbage in the garbage collection vehicle is Since the loading capacity differs depending on the model, it is necessary to discharge the amount of garbage discharged from the discharge port 14 according to the garbage loading capacity of the garbage collection vehicle. If this is the case, you can adjust the forward speed of the pushing plate 3 of the garbage compression device A to be synchronized with the rotating speed of the rotating cylinder 100 of the crushing device, but there are many types of garbage collection vehicles that come to collect the garbage. In the case where the loading time is longer than that, it is necessary to adjust the adjustment, which is difficult and hinders the loading operation.

The present invention makes this difficult adjustment possible by simply switching the switch in the select circuit to adjust the discharge speed (in this embodiment, the forward speed of the pusher plate and the rotational speed of the rotary drum) to match the garbage loading capacity of the garbage collection vehicle. As a result, the garbage collection vehicle can be connected to the discharge port 14 of the crushing device B, and the switch of the select circuit can be changed according to the garbage loading capacity. Control P is performed by moving a worm reducer 17 with a pulse motor 16 and moving a flow rate adjustment shaft 19 of a variable displacement hydraulic pump 1B, as shown in FIG. 21 is a switching valve, 22 is a check valve, 23 is a variable flow rate adjustment valve, and 24 is an IJ-F valve.

25 is a motor for driving the variable displacement pump 18.

The pulse motor 16 detects the number of input signal pulses with a counter, and when a preset count is reached, the input signal pulses are cut and the pulse motor 16 is stopped. Accordingly, the counter selection circuit is configured to synchronize the forward speed of the pushing plate 3 of the compression device A and the rotational speed of the rotary drum 10 of the crushing device B to perform switching. The pulse motor 16 has a step angle of 1.8° to 15° relative to the pulse.
Since it is as small as 100°, fine adjustment is possible, and by detecting the number of pulses, the amount of garbage discharged can be detected, and remote control using electric signals is also possible.

In this example, the ejection mechanism was a push plate and a rotary cylinder, but only the rotary cylinder, a screw conveyor, a belt conveyor,
Or any combination thereof will produce similar effects.

In this way, the amount of garbage discharged from the garbage processing equipment that stores and discharges garbage and the loading capacity of various types of garbage collection vehicles are synchronized by process control, and garbage is always transported safely and smoothly. It is an excellent and advanced technical invention that has functions and effects and is of great benefit to the industry.
