Embodiment Construction
[0034] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.
[0035] Such as figure 1 Shown is a schematic diagram of the principle of an embodiment of the hydraulic control system of a sweeper vehicle of the present invention. In this embodiment, the sweeper hydraulic control system includes: a sweeping disc motor, a first reversing valve 4 and a sweeping disc speed regulating mechanism. The sweeper motor is used to drive the sweeper of the sweeper to rotate. For different types of sweeper, different numbers of sweeper motors can be included, such as the left sweeper motor and the right sweeper motor on the left and right sides of the sweeper. , Or include only one sweeping motor, or include sweeping motors with more than three sweeping positions.
[0036] The oil inlet P1 of the first reversing valve 4 and the other working devices of the sweeper are both connected to the main working oil ci...

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 a control method of a sweeper vehicle. Background technique [0002] The sweeper is a movable automatic cleaning equipment for road cleaning, garbage recycling and transportation. It is suitable for cleaning roads in factories, highways, parks, squares and other roads. The sweeping disc on the sweeper is used to clean the road surface. By setting the different speeds of the sweeping disc, the road can be cleaned in different situations. [0003] Most of the sweeping speed control methods used by sweepers on the market currently have some defects. That is, when operating the sweeper, you first need to select the speed gear according to the road conditions (usually three speeds: high, medium, and low), and then start the one-button operation, successively the suction cup descends, the sweeper descends and extends, and the sweeper rotates , And the work begins. At t...
