Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of self-loading and unloading garbage trucks, and particularly relates to a self-loading and unloading garbage truck control system and a self-loading and unloading garbage truck. BACKGROUND

[0002] At present, the actions of the scraping slide plate mechanism and the feeding mechanism of the self-loading and unloading garbage truck are usually controlled separately, for example, as shown in the figure, first, the feeding mechanism 01 loads the garbage into the garbage box 03 through the feeding opening 04, and then the scraping slide plate mechanism 02 pushes the garbage into the garbage box 03 and compresses the garbage to a certain extent to provide space for subsequent garbage loading. Since the scraping slide plate mechanism 02 and the feeding mechanism 01 perform corresponding actions under separate control, when the loading capacity of the garbage box 03 reaches the limit (i.e., the garbage box 03 is full), if the operator does not notice the full loading condition and continues to operate the feeding mechanism 01 to perform the feeding operation, the garbage will overflow due to the lack of sufficient loading space in the garbage box, causing secondary pollution.

The described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0031] Referring to Figure 1 , referring to Figure 1 , self-loading and unloading garbage truck: a device for loading garbage into a garbage bin and transporting it to a garbage disposal plant, including lifting mechanism, leg mechanism, feeding mechanism, sliding plate mechanism, garbage bin, etc.

[0032] Lifting mechanism: lifting the garbage can to the entrance of the garbage bin, i.e. performing lifting operation.

[0033] Leg mechanism: the component supporting the self-loading and unloading garbage truck, i.e. performing supporting operation.

[0034] Loading mechanism 01: the component that pours the garbage in the garbage can into the garbage can 03, that is, performs the loading operation.

[0035] Scraper slide plate mechanism 02: the component that pushes the garbage poured into the garbage can 03 at the entrance 04 of the garbage can 03 into the interior of the garbage can 03 and compresses the garbage to a certain extent, that is, performs the scraper operation and the compression operation.

[0036] Lifting oil cylinder: when the piston rod of the lifting oil cylinder extends, it drives the lifting mechanism to perform the lifting operation.

[0037] Supporting oil cylinder: when the piston rod of the supporting oil cylinder extends, it drives the supporting mechanism to support, and when the piston rod of the supporting oil cylinder retracts, it drives the supporting mechanism to retract, that is, drives the supporting mechanism to perform the supporting operation.

[0038] Loading oil cylinder: when the piston rod of the loading oil cylinder extends, it drives the loading mechanism to perform the loading operation to pour the garbage in the garbage can into the garbage can 03.

[0039] Slide plate oil cylinder: when the piston rod of the slide plate oil cylinder extends, it drives the scraper slide plate mechanism 02 to perform the compression operation to compress the garbage in the garbage can 03.

[0040] Scraper oil cylinder: when the piston rod of the scraper oil cylinder extends, it drives the scraper slide plate mechanism to perform the scraper operation to push the garbage at the entrance 04 of the garbage can 03 into the interior of the garbage can 03.

[0041] As can be known from the background art description, when the loading capacity of the garbage can 03 reaches the limit, the garbage can 03 is full, at this time, the garbage in the garbage can 03 pushes back the scraper slide plate mechanism 02, and the force is transmitted to the slide plate oil cylinder driving the slide plate mechanism 02 to run, and the rodless cavity oil pressure of the corresponding slide plate oil cylinder reaches the preset value, based on this point, the inventor provides a self-loading and unloading garbage truck control system and a self-loading and unloading garbage truck to reduce secondary pollution of the self-loading and unloading garbage truck.

[0042] Referring to Figure 2 The self-loading and unloading garbage truck control system provided by the embodiment of the application comprises a slide plate oil cylinder 7, a loading oil cylinder 8 and a plurality of reversing valves, wherein the piston rod of the slide plate oil cylinder 7 is connected with the scraper slide plate mechanism 02 and drives the scraper slide plate mechanism 02 to perform the compression operation; the piston rod of the loading oil cylinder 8 is connected with the loading mechanism 01 and drives the loading mechanism 01 to perform the loading operation; the plurality of reversing valves are communicated with the slide plate oil cylinder 7 or the loading oil cylinder 8 through pipelines, and when the oil pressure in the rodless cavity of the slide plate oil cylinder 7 reaches a threshold value, the oil pressure in the rodless cavity of the loading oil cylinder 8 is greater than or equal to the oil pressure in the rod cavity of the loading oil cylinder 8.

[0043] The self-loading and unloading garbage truck control system of the application indicates that the loading capacity of the garbage box of the automatic loading and unloading garbage truck reaches the limit when the oil pressure in the rodless cavity of the slide plate oil cylinder 7 reaches the threshold value, at this time, the oil pressure in the rodless cavity of the feeding oil cylinder 8 is greater than or equal to the oil pressure in the rod cavity of the feeding oil cylinder 8, that is, the feeding oil cylinder 8 cannot continue to drive the feeding mechanism to perform the feeding operation. Therefore, the feeding oil cylinder 8 stops the feeding operation when the garbage box is fully loaded, which avoids the phenomenon that the artificial operation error continues to feed after the garbage box is fully loaded, resulting in secondary pollution caused by garbage leakage.

[0046] The oil outlet of the second directional control valve 2 is in communication with the rod cavity of the slide plate oil cylinder 7; when the second directional control valve 2 is in the left position, the oil inlet of the second directional control valve 2 and the oil outlet of the second directional control valve 2 are cut off; when the second directional control valve 2 is in the right position, the oil inlet of the second directional control valve 2 and the oil outlet of the second directional control valve 2 are in communication.

[0047] The oil outlet of the third directional control valve 3 is in communication with the oil inlet of the fifth directional control valve 5, and the oil inlet of the third directional control valve 3 and the oil outlet of the third directional control valve 3 are cut off; when the third directional control valve 3 is in the right position, the oil inlet of the third directional control valve 3 and the oil outlet of the third directional control valve 3 are in communication.

[0048] The oil outlet of the fifth directional control valve 5 is in communication with the rodless cavity of the slide plate oil cylinder 7; when the fifth directional control valve 5 is in the left position, the oil inlet of the fifth directional control valve 5 and the oil outlet of the fifth directional control valve 5 are cut off; when the fifth directional control valve 5 is in the right position, the oil inlet of the fifth directional control valve 5 and the oil outlet of the fifth directional control valve 5 are in communication.

[0050] The oil outlet of the sixth reversing valve 6 is communicated with the rod cavity of the upper loading oil cylinder 8; when the sixth reversing valve 6 is located at the left position, the oil inlet of the sixth reversing valve 6 and the oil outlet of the sixth reversing valve 6 are cut off; when the sixth reversing valve 6 is located at the right position, the oil inlet of the sixth reversing valve 6 and the oil outlet of the sixth reversing valve 6 are conducted.

[0051] The first reversing valve 1, the second reversing valve 2, the third reversing valve 3, the fourth reversing valve 4, the fifth reversing valve 5 and the sixth reversing valve 6 can be hydraulic control reversing valves, and can also be electromagnetic reversing valves. In some embodiments of the present application, the first reversing valve 1, the second reversing valve 2, the third reversing valve 3, the fourth reversing valve 4, the fifth reversing valve 5 and the sixth reversing valve 6 are electromagnetic valves. By being provided as electromagnetic valves, control is facilitated.

[0053] The hydraulic oil enters the rodless cavity of the upper loading oil cylinder 8 through the first reversing valve 1 to push the upper loading oil cylinder 8 to extend for upper loading operation, and the hydraulic oil in the rod cavity of the upper loading oil cylinder 8 enters the rodless cavity of the sliding plate oil cylinder 7 through the sixth reversing valve 6 and the fifth reversing valve 5 to push the sliding plate oil cylinder 7 to extend to compress and push the garbage in the garbage can to the inside of the garbage can to reserve loading space for the garbage being loaded. When the garbage can is not full, the counterforce F of the garbage in the garbage can to the sliding plate oil cylinder 7 is less than the set working pressure of the system, the upper loading oil cylinder 8 continues to be pushed by the hydraulic oil to perform upper loading operation, and the sliding plate oil cylinder 7 continues to compress and push the garbage to the inside of the garbage can to reserve loading space for the garbage being loaded. When the garbage can is full, the counterforce F of the garbage in the garbage can to the sliding plate oil cylinder 7 is greater than or equal to the set working pressure of the system, the hydraulic oil is insufficient to continue to push the upper loading oil cylinder 8 to perform upper loading operation, and the upper loading operation stops, thereby achieving automatic control of stopping the upper loading operation when the garbage can is full.

The hydraulic oil enters the rod cavity of the upper loading oil cylinder 8 through the first reversing valve 1, the fourth reversing valve 4 and the fifth reversing valve 5 to push the upper loading oil cylinder 8 to retract, so that the upper loading mechanism can be maintained.

[0056] When in the up-maintenance mode of the scraping plate mechanism, the first reversing valve 1 is located at the right position, the second reversing valve 2, the fourth reversing valve 4 and the fifth reversing valve 5 are all located at the right position, and the third reversing valve 3 and the sixth reversing valve 6 are all located at the left position.

The hydraulic oil enters the rod cavity of the sliding plate oil cylinder 7 through the first reversing valve 1 and the second reversing valve 2, and the sliding plate oil cylinder 7 retracts under the push of the hydraulic oil, so that the scraping plate mechanism can be maintained.

When the garbage can is not full, the counterforce F of the garbage in the garbage can to the sliding plate oil cylinder 7 is less than the set working pressure of the system, the feeding oil cylinder 8 continues to be pushed by the hydraulic oil to perform the feeding operation, and the sliding plate oil cylinder 7 continues to compress and push the garbage to the inside of the garbage can to reserve the loading space for the garbage being fed.
