Abstract
The utility model relates to an automatic backward device for a compression push plate of the garbage vehicle, and the automatic backward device is characterized in that an oil circuit of a non-rod cavity which is provided with a rod cavity and a push plate oil cylinder of a sliding plate oil cylinder is provided with an outer controlling sequence valve. The outer controlling sequence valve uses an oil circuit to connect with the oil circuit of the non-rod cavity of the scraper oil cylinder to change the setting valve of the outer controlling sequence valve, and can obtain different garbage compression ratios. When filling the garbage, the pressure in the non-rod cavity of the scraper oil cylinder can quickly rise with the continuous rising of the sliding plate oil cylinder. When the pressure rises to the setting pressure valve of the outer controlling sequence valve, the outer controlling sequence valve is opened after the garbage is pressed tightly, and the oil in the non-rod cavity of the pull plate oil cylinder can return the oil cylinder through the outer controlling sequence valve. The push plate can automatically be backward a little, and the garbage vehicle is filled with a little garbage, and the garbage is compressed a little, and then the push plate can be backward a little, and this action is repeated until the garbage is compressed tightly to a burden quality. The automatic backward device has a rational structure, and is safe and reliable to use, so the automatic backward device can realize the automation of the filling and compressing of the garbage, and the automatic backward device improves the work efficiency.
Description
Technical field:
The utility model belongs to the automobile hydraulic device, the push pedal hydraulic pressure compression set that especially a kind of improved compression type refuse is automobile-used.
Background technology:
Existing compression type garbage truck, after rubbish is unsnatched in the push pedal propelling movement, the original place of often push pedal being withdrawn, after loading rubbish again, recompress, like this, push pedal and scraper plate bi-directional compression car load rubbish rubbish just occurs and do not press tightly, press unreal phenomenon, cause waste-skip out of reach burden rating, reduced work efficiency.
Summary of the invention:
The purpose of this utility model is that the automobile-used push pedal of a kind of improved compression type refuse of design retreats hydraulic efficiency gear, when compression type garbage truck filling rubbish, load some rubbish, just compression is a bit, after compressing compacting, push pedal retreats a bit automatically, some rubbish that recharge, and compression is a bit, repetitive operation, until reaching specified rubbish carrying capacity, realize the automation of rubbish filling process, improve the work efficiency of waste-skip.
The purpose of this utility model is achieved like this: a kind of by fuel tank, oil pump, main valve, hydraulic control one-way valve, compression indicator, oil circuit, the push pedal oil cylinder, push pedal, skateboard tank, slide plate, the scraper plate oil cylinder, the automatic setback device of waste-skip compression push pedal that scraper plate is formed, it is characterized in that on the oil circuit of the rodless cavity of the rod chamber of skateboard tank and push pedal oil cylinder, an external control sequence valve being set, this external control sequence valve also joins with the oil circuit of the rodless cavity of oil circuit and scraper plate oil cylinder, the settling pressure that changes the external control sequence valve can obtain different rubbish compression ratios, during the rubbish that in compression garbage truck, loads, constantly up along with skateboard tank, this moment, two hydraulic fluid ports of scraper plate oil cylinder all sealed, the rubbish that the scraper plate oil cylinder is subjected to rises rapidly to the antagonistic force of scraper plate, the rodless cavity internal pressure of scraper plate oil cylinder also rises thereupon, when pressure is raised to the pressure of external control sequence valve setting, after rubbish compresses compacting, the external control sequence valve is opened, the fluid of push pedal oil cylinder rodless cavity enters the rod chamber of skateboard tank by the external control sequence valve, get back to fuel tank by main valve, contract a bit after the push pedal automatically, some rubbish recharge, compression a bit, contract after the push pedal more a bit, repetitive operation realizes the automatic fallback function of push pedal, return the original place until push pedal, car load rubbish all compresses compacting, reach burden rating, both realize the automation of rubbish filling, improved the work efficiency of waste-skip again.
The utility model is rational in infrastructure, and is safe and reliable, both realized the automation of filling compressed garbage, guaranteed the burden rating of waste-skip again, improved the work efficiency of waste-skip.
The automatic setback device of the utility model being carried below in conjunction with drawings and Examples of waste-skip compression push pedal is further described.
Description of drawings:
Fig. 1 is the hydraulic diagram of the automatic setback device of waste-skip that the utility model is carried compression push pedal.
The specific embodiment:
As can be seen from Figure 1: a kind of by fuel tank 1, oil suction filter 2, oil pump 3, main valve 4, compression indicator 5, hydraulic control one-way valve 6, push pedal oil cylinder 10, push pedal 11, oil circuit 7,8, skateboard tank 16, oil circuit 15, scraper plate oil cylinder 18, oil circuit 20,21, pressure relay 22, the automatic setback device of waste-skip compression push pedal that return filter 23 is formed, it is characterized in that on the oil circuit 15 of the rod chamber 14 of the oil circuit 8 of the rodless cavity 9 of push pedal oil cylinder 10 and skateboard tank 16, external control sequence valve 13 being set with oil circuit 12, external control sequence valve 13 also is connected with the oil circuit 20 of the rodless cavity 19 of scraper plate oil cylinder 18 by oil circuit 17, change the settling pressure value of external control sequence valve 13, can obtain different rubbish compression ratios, the automatic fallback function of waste-skip push pedal 11 realizes by external control sequence valve 13, when after the release of car load rubbish is laid down in push pedal 11, loading rubbish again, under the instruction of the Programmable Logic Controller that waste-skip is equipped, push pedal oil cylinder 10 drives push pedal 11 and has made an amount of retraction, scraper plate oil cylinder 18 actions this moment, scraper plate with rubbish load into Che Nei and and 11 pairs of rubbish of push pedal make bi-directional compression, constantly up along with skateboard tank 16, the rubbish of filling is more and more, two hydraulic fluid ports of scraper plate oil cylinder 18 all seal at this moment, scraper plate oil cylinder 18 is under the effect of rubbish antagonistic force, pressure in the rodless cavity 19 of scraper plate oil cylinder 18 rises rapidly, when pressure rises to the setting pressure of external control sequence valve 13, the compacted compacting of rubbish this moment, external control sequence valve 13 is opened, hydraulic oil enters the rodless cavity of skateboard tank 16 through the B2 hydraulic fluid port, hydraulic oil in the rodless cavity 9 of push pedal oil cylinder 10 is entered the rod chamber 14 of skateboard tank 16 through external control sequence valve 13 by oil circuit 12, get back to fuel tank 1 by main valve 4, the oil pressure of push pedal oil cylinder 10 rodless cavities 9 descends and discharges, the promotion that is subjected to scraper plate oil cylinder 18 to continue to load the rubbish of coming in, push pedal 11 just retreats a bit automatically, pressure release in rodless cavity 9 finishes, push pedal 11 and push pedal oil cylinder 10 stop, external control sequence valve 13 cuts out at this moment, 10 actions of push pedal oil cylinder, at this moment scraper plate oil cylinder 18 continues filling and compressed garbage, repeat above-mentioned action, be that push pedal 11 retreats a bit automatically, rubbish loads, compression a bit, until car load rubbish is compressed compacting, reach burden rating, improve the work efficiency of waste-skip.
