Description

Technical Field

[0001] The invention relates to a wheel loader seat with a working operating system following the movement, belonging to the technical field of loaders. Background Art

[0002] Wheel loaders are widely used engineering machinery, suitable for various harsh working conditions. During the normal operation of the loader, it is necessary to frequently control the movement of the boom and bucket. The relevant control system is the working control system. The system is divided into two types according to the source of the control power: hydraulic pilot control and mechanical flexible shaft control. Considering the cost and usage habits, most of the loaders currently used in China are equipped with a mechanical flexible shaft control system, and the seat position is adjustable, while the position of the control mechanism assembly is not adjustable. Figure 1 As shown, the seat assembly 1 is connected to the guide rail 2, the guide rail 2 is connected to the cab base 3, the relative position of the guide rail 2 and the cab base 3 can be adjusted within a certain travel range, the operating mechanism assembly 4 is connected to the cab base 3, the operator can only adjust the front and rear position and stiffness of the seat assembly 1, but cannot adjust the operating mechanism assembly 4. When facing users of various body shapes, the operating comfort is poor, and if working in an unnatural posture for a long time, it is easy to cause related occupational diseases. Summary of the invention

[0003] The technical problem to be solved by the present invention is to solve the problem that the position of the operating mechanism assembly of the mechanical flexible shaft operating system of the existing wheel loader cannot be adjusted, resulting in poor operating comfort of the loader.

[0004] In order to solve the above technical problems, the technical solution of the present invention is to provide a wheel loader seat with a working control system, including a cab base, a guide rail connected to the cab base, and a slidable seat assembly on the guide rail. The characteristic is that the seat assembly is provided with an adjustable mounting bracket combination that can be adjusted in the front and rear, left and right, and up and down directions, and the adjustable mounting bracket combination is provided with a control mechanism assembly.

[0005] Preferably, the adjustable mounting bracket combination includes a first mounting bracket and a second mounting bracket, one end of the second mounting bracket is connected to the operating mechanism assembly, one end of the first mounting bracket is connected to the other end of the second mounting bracket, and the other end of the first mounting bracket is connected to the seat assembly.

[0006] Preferably, both sides of the first mounting bracket and both sides of the second mounting bracket are provided with elongated holes for position adjustment in the front-to-back, left-to-right, and up-down directions.

[0007] Preferably, an elongated hole is provided on one side of the second mounting bracket to enable the operating mechanism assembly to move in the left-right direction; an elongated hole is provided on the other side of the second mounting bracket or on one side of the first mounting bracket to enable the first mounting bracket and the second mounting bracket to move up and down relative to each other; and an elongated hole is provided on the other side of the first mounting bracket to enable the first mounting bracket to move forward and backward on the seat assembly.

[0008] Preferably, the first mounting bracket and the second mounting bracket are both right-angle bending structures.

[0009] The advantages of the present invention are:

[0010] 1. The relative position of the operating mechanism assembly and the seat assembly can be adjusted separately in the front-to-back, left-to-right, and up-to-down directions to ensure the comfort of operators of all sizes;

[0011] 2. When adjusting the position of the seat assembly, the operating mechanism assembly moves with it and maintains the same position as the seat assembly, avoiding repeated adjustment of the position of the operating mechanism assembly by a fixed user, thus ensuring convenient and comfortable use.
