Self-Propelled Bagging Machine for Storing Grain in a Sleeve

Abstract

A self-propelled bagging machine stores grain in a sleeve and comprises an upper receiving hopper with an outlet leads to a grain discharge tunnel and is mounted on a chassis equipped with a running gear and dragging pole. The running gear comprises a back single-shaft running gear that is connected to the wheels and a smaller front steering running gear. The grain bagging machine further includes a dual compensated braking device with an adjustable primary hydraulic braking mechanism and an adjustable secondary hydraulic braking mechanism which act simultaneously on the back shaft of the bagging machine. The mechanic articulation is mounted on the chassis and is sensitive to pulling variations and activates an inverted operation hydraulic pump for reception or release of braking fluid to the secondary braking mechanism circuit for braking compensation.

1 - 12 . (canceled) 
     
     
         13 . A dual compensated braking device to be applied to the self-propelled grain bagging machine as in any of the preceding claims, CHARACTERIZED in that it comprises:
 a primary braking mechanism made up of: a primary circuit with braking fluid for transmitting working pressure on a primary caliper, such pressure being generated by means of a first hydraulic pump; and   a secondary braking mechanism made up of: a secondary circuit with braking fluid for transmitting working pressure on a secondary caliper, such pressure being generated by means of a second hydraulic pump;   where both primary and secondary calipers act on opposite sides of a disk brake attached to an effector shaft that comprises a first sprocket connected by means of a drive chain to a second sprocket mounted on the shaft, connected to the back running gear wheels to allow the bagging machine to move, and where compression/decompression of a spring sensitively assembled on the chassis in reply to pulling variations during the bagging machine operation causes such spring to trigger a bolt that activates a cam that triggers a third inverted operation hydraulic pump for reception/release of braking fluid from/to the secondary braking mechanism circuit for braking force compensation.   
     
     
         14 . The braking device as in  claim 13 , further CHARACTERIZED in that the spring is mounted between an upper plate and a lower plate that pivot independently from each other as a result of the push received by the bagging machine as it moves forward. 
     
     
         15 . The braking device as in  claim 13 , CHARACTERIZED in that the primary circuit working pressure is adjusted to range between 50 kg/cm 2  and 150 kg/cm 2  approximately. 
     
     
         16 . The braking device as in  claim 15 , CHARACTERIZED in that such primary circuit working pressure is equal to about 70% of the dual compensated braking device total braking capacity. 
     
     
         17 . The braking device as in  claim 13 , CHARACTERIZED in that the secondary circuit working pressure is adjusted to range between 15 kg/cm 2  and 45 kg/cm 2  approximately. 
     
     
         18 . The braking device as in  claim 17 , CHARACTERIZED in that such secondary circuit working pressure is equal to about 30% of the dual compensated braking device total braking capacity.
