, Description:TECHNICAL FIELD
[001] The embodiments herein relate to a draft sensing device for an agricultural vehicle. Further, embodiments herein relate to a method of mounting the draft sensing device in the agricultural vehicle. Further, embodiments herein relate to a method of pre-adjusting spring force in draft sensing device in the agricultural vehicle.

BACKGROUND
[002] Generally, agricultural vehicles such as tractors or other similar vehicles are primarily used in agricultural field operations. Typically, a three-point hitch is used to attach implements (earth working machines) to the vehicle, where the implement is being pulled by the vehicle in agricultural fields to condition the soil for cultivation. A draft sensing device is used to sense various ranges of loads including low to high range of loads from the external mounted implements and provide feedback to a hydraulic hitch control valve to limit the depth of implement thereby preventing stalling of vehicle or provide depth as per requirement of respective operation. As shown in fig. 1a and fig. 1b, conventional draft sensing device (D) uses double springs (S1, S2) for sensing draft load acting on the implement. The pre-adjustment of load of springs (S1, S2) in the draft sensing device (D) is achieved by adding shims. The process of adding shims into the draft sensing device (D) is cumbersome and time consuming. Further, a housing (H) of the conventional draft sensing device (D) is mounted onto the lift housing (LH) in a two plane mounting arrangement, where one plane is transverse to the other plane. For example, a first set of bolts (B1) is used for securing the housing (H) of the draft sensing device (D) with the lift housing (LH) in a vertical plane and a second set of bolts (B2) is used for securing the housing (H) of the draft sensing device (D) with the lift housing (LH) in a horizontal plane.
[003] Therefore, there exists a need for a draft sensing device, which obviates the aforementioned drawbacks. Further, there exists a need for a method of mounting the draft sensing device in the agricultural vehicle. Furthermore, there exists a need for a method for pre-adjusting spring force in the draft sensing device of the agricultural vehicle, which obviates the aforementioned drawbacks.

[0041] Fig. 6 depicts a flowchart indicating a method (300) for pre-adjusting spring (106) force in the draft sensing device (100) of the agricultural vehicle, according to embodiments as disclosed herein. For the purpose of this description and ease of understanding, the method (300) is explained herein below with reference to pre-adjusting spring (106) force in the draft sensing device (100) of the agricultural vehicle such as but not limited to a tractor. However, it is also within the scope of this invention to practice/implement the entire steps of the method (300) in a same manner or in a different manner or with omission of at least one step to the method (300) or with any addition of at least one step to the method (300) for pre-adjusting spring (106) force in the draft sensing device (100) of the agricultural vehicle in any other off-road vehicles or any other applications without otherwise deterring the intended function of the method (300) as can be deduced from the description and corresponding drawings. At step (302), the method (300) includes moving, by an adjuster (104) of the draft sensing device (100), a first end spring retainer (108) in a direction towards or away from a clevis (116) by adjustably moving the adjuster (104) with respect to a housing (102) of the draft sensing device (100) thereby adjusting the load of the spring ((s) (106)) in the draft sensing device (100).
[0042] The method (300) includes defining a plurality of internal threads (102T) at a first end (102F) of the housing (102) of the draft sensing device (100). Further, the method (300) includes defining a plurality of external threads (104T) on the adjuster (104).
[0043] The method step (302) of adjustably moving the adjuster (104) with respect to a housing (102) of the draft sensing device (100) thereby adjusting the load of the spring ((s) (106)) in the draft sensing device (100) includes, adjusting connecting the adjuster (104) into the first end (102F) of the housing (102) by engaging the external threads (104T) of the adjuster (104) with the internal threads (102T) of the housing (102).
[0044] Further, the method (300) includes loading the spring (106) on the spindle (112) through a spacer (114), and in between the first end spring retainer (108) and the second end spring retainer (110). Furthermore, the method (300) includes engaging the first end spring retainer (108) with the clevis (116) by adjustably inserting one end of a body (112B) of the spindle (112) into the clevis (116).
[0045] The technical advantages of the draft sensing device (100) are as follows. The draft sensing device is fastened to a hydraulic power lift housing in a single mounting plane configuration. The draft sensing device includes a spacer which restricts full compression of spring thereby enhancing the durability and lifetime of the spring.
