Abstract
The utility model relates to a steering mechanism of a plant protection machine. The mechanism comprises a conversion valve block, a steering oil cylinder, a steering support base, a steering arm, wheels, a steering shaft and a machine body. The front steering oil cylinder forms a triangular connection mechanism through the steering support base, the steering arm and the steering shaft. The triangular connection mechanism is installed on the machine body. The wheels are installed on the triangular connection mechanism through the steering shaft. The triangular connection mechanism with the wheels and the machine body are arranged in front and back rows in a bilaterally symmetrical manner along the longitudinal axis. According to the mechanism disclosed by the utility model, the single-bridge steering disadvantages are overcome; the four-wheel steering, the crab walk steering and the single-bridge steering of vehicles can be satisfied; therefore, the through capacity of the plant protection machine is increased; the plant protection machine is low in turning radius and multiple in steering way; the through capacity of the machine is strong; and the application performance of the plant protection machine is increased.
Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a plant protecting machinery, relates in particular to the steering mechanism of a plant protecting machinery.
Background technology
At present; The equipment for plant protection steering mechanism of domestic production is simple, and turning to during work only can realize that single bridge turns to, and can not realize four-wheel steering, the function conversion that the crab row turns to and single bridge turns to; The function of this steering mechanism is unfavorable for that equipment for plant protection reduces radius of turn when operating in the field; Particularly can not satisfy crab row and turn to,, make the crop loss of field middle and later periods too big for being easy to roll crop when the high culm plant farm work.For this reason, design and develop and a kind ofly can satisfy that vehicle implementation four-wheel steering, crab row turns to and the steering mechanism of the equipment for plant protection that single bridge turns to, thereby the handling capacity that improves equipment for plant protection is necessary fully.
The utility model content
The purpose of the utility model be to provide a kind of relatively simple for structure, can realize that four-wheel steering, crab row turn to and single bridge turns to the steering mechanism of the equipment for plant protection of three kinds of steering modes.
The technical scheme of the utility model is: the steering mechanism of a plant protecting machinery comprises: the switching valve piece, turn to oil cylinder, turn to bearing, steering arm, wheel, steering spindle, body; To before turn to oil cylinder to constitute triangle bindiny mechanism through turning to bearing, steering arm, steering spindle, triangle bindiny mechanism is installed on the body, and wheel is installed in the triangle bindiny mechanism through steering spindle; Forward and backward two rows of the triangle bindiny mechanism of band wheel and the left and right symmetric arrangement of body longitudinal axis.
The hydraulic fluid port of described switching valve piece links to each other with the big chamber of front-seat left side steering oil cylinder, and another hydraulic fluid port links to each other with the big chamber of front-seat the right steering oil cylinder.
The hydraulic fluid port of described switching valve piece turns to the big chamber of oil cylinder to link to each other with the player No.5 limit, and another hydraulic fluid port turns to the big chamber of oil cylinder to link to each other with the back right limit.
The utility model adopts the good effect that produces after the technique scheme to be: overcome the shortcoming that single bridge turns to; Can satisfy that vehicle implementation four-wheel steering, crab row turns to and single bridge turns to; Thereby improve the handling capacity of equipment for plant protection, its radius of turn is little, and steering mode is many; The handling capacity of machine is strong, has improved the serviceability of equipment for plant protection.
Description of drawings
Fig. 1 is the front-wheel steer position view of the steering mechanism of the utility model one plant protecting machinery.
Fig. 2 is the four-wheel steering position view of the steering mechanism of the utility model one plant protecting machinery.
Fig. 3 is the crab row steering position sketch map of the steering mechanism of the utility model one plant protecting machinery.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: like Fig. 1 ~ shown in Figure 3, the steering mechanism of a plant protecting machinery comprises: switching valve piece 1, turn to oil cylinder 2, turn to bearing 3, steering arm 4, wheel 5, steering spindle 6, body 7; To turn to oil cylinder 2 to constitute triangle bindiny mechanism through turning to bearing 3, steering arm 4, steering spindle 6, triangle bindiny mechanism is installed on the body 7, and wheel 5 is installed in the triangle bindiny mechanism through steering spindle 6; Two arranged before and after the triangle bindiny mechanism of band wheel 5 is divided into, front and back two row's wheels satisfy the wheelbase size, preceding, row's triangle bindiny mechanism and the left and right symmetric arrangement of body longitudinal axis; The interlock that left and right wheel 5 turns to is by the loculus constancy of volumeization that turns to oil cylinder 2 and realize.
Switching valve piece 1 is installed in the top of body, and the hydraulic fluid port A1 of switching valve piece 1 links to each other with the big chamber of front-seat left side steering oil cylinder 2, and another hydraulic fluid port B1 links to each other with the big chamber of front-seat the right steering oil cylinder 2.The hydraulic fluid port A2 of switching valve piece 1 turns to the big chamber of oil cylinder 7 to link to each other with the player No.5 limit, and another hydraulic fluid port B2 turns to the big chamber of oil cylinder 2 to link to each other with the back right limit, and left and right limit turns to the loculus hydraulic fluid port of oil cylinder 2 to interconnect.
When the magnetic valve of switching valve piece 1 mediates, realize front-wheel steer; When being in left position, realizes by magnetic valve four-wheel steering; When being in location right, realizes by magnetic valve that the crab row turns to.
The utility model is simple in structure; Left-right symmetric; Organization of production is convenient, be beneficial to the crack, highland of realizing equipment for plant protection realization, especially steering mode can supply the user to select; Possess and to satisfy that vehicle implementation four-wheel steering, crab row turns to and the steering mechanism of the equipment for plant protection that single bridge turns to, thereby improve the handling capacity of equipment for plant protection.Adapt to the different work operating mode of machine, can realize that radius of turn is little, the handling capacity that improves machine is strong, has promoted the serviceability of equipment for plant protection.
