Embodiment Construction

[0034] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0035] Such as figure 1 As shown, it is a principle schematic diagram of an embodiment of the hydraulic control system of the sweeping vehicle of the present invention. In this embodiment, the hydraulic control system of the sweeping vehicle includes: a sweeping motor, a first reversing valve 4 and a speed regulating mechanism for sweeping. The sweeping motor is used to drive the sweeping of the sweeping vehicle to rotate. For different types of sweeping vehicles, different numbers of sweeping motors can be included, such as left sweeping motors and right sweeping motors on the left and right sides of the sweeping vehicle, etc. , or include only one sweeping motor, or include sweeping motors with more than three cleaning positions.

[0036] The oil inlet P1 of the first reversing valve 4 is connected to the main work...

Abstract

The invention relates to a road sweeper hydraulic control system and method. The road sweeper hydraulic control system comprises a sweeper disc motor, a first reversing valve (4) and a sweeper disc speed adjusting mechanism, wherein the oil inlet of the first reversing valve and other working devices of the road sweeper are connected with the main working oil path (13) of the road sweeper, the working oil outlet of the first reversing valve communicates with the oil inlet cavity of the sweeper disc motor, and the first reversing valve is used for cutting off or switching the flow direction of the oil path between the oil inlet and the working oil outlet of the first reversing valve (4); the sweeper disc speed adjusting mechanism is connected onto the subsequent oil path of the working oil outlet of the first reversing valve (4) and used for adjusting the operating speed of the sweeper disc motor by diverting the hydraulic oil flowing from the working oil outlet of the first reversing valve (4) to the sweeper disc motor; and the oil pressure of the main working oil path (13) is maintained above the preset pressure threshold value. The road sweeper hydraulic control system and method have the benefits that when the sweeper disc of the road sweeper works at different speeds, the other actuating elements of the road sweeper can conveniently and smoothly switch to the normal working states.

Description

technical field [0001] The invention relates to the field of control, in particular to a hydraulic control system and control method for a sweeping vehicle. Background technique [0002] Sweeper is a kind of driving automatic cleaning equipment that realizes road cleaning, garbage recycling and transportation. It is suitable for cleaning roads such as factories, highways, parks, and squares. The sweeping disc on the sweeper is used to clean the road surface. By setting different speeds of the sweeping disc, the cleaning of the road surface in different situations can be realized. [0003] Most of the sweeping speed control methods adopted by sweeping vehicles on the market have some defects. That is to say, when operating the sweeper, you first need to select the speed gear according to the road conditions (usually the speed is divided into three gears: high, medium, and low), and then start the one-button operation, the suction cup descends sequentially, the sweeping disk ...
