A silo unloader has an auger collector for moving material to an impeller operable to discharge material from a tower silo. A sprocket and endless chain secured to a transition assembly mounted on the impeller drives the collector around the silo wall. Wheels on the outer end of the collector and wheels on a biased arm on the inner end of the frame stabilize the unloader in the silo. A stop pivotally connected to the collector limits its backward movement by lifting the collector from the material.

Silo unloader

A bottom unloader having a material conveyor for moving material from a hopper centrally located in a bin to a location outside of the bin. A drive apparatus mounted on the outer end of the conveyor operates the conveyor and adjusts the tension on the conveyor chain. The outer end of the conveyor has a door that is clamped to a closed position with eccentric clamping locks. An elongated auger collector is mounted on a rotatable turntable located in the central hopper. A cap having a side opening for the auger collector is mounted on the turntable. The auger collector is drivably connected with the conveyor so that, when the conveyor is operated, the auger collector is rotated. A separate drive operated with a hydraulic motor is used to move the auger collector in a circular path.

Bottom unloader

A livestock feeding apparatus having an endless belt supported on an elongated table above a feed bunk by a plurality of stands. The stands are laterally and vertically adjustable to level the apparatus and accommodate different sized bunks. The belt has an upper run that rides on a wood deck secured to the support. An idler pulley and drive pulley engages one end of the belt opposite ends. The belt is retained in driving engagement with the drive pulley by a driven roller engageable with the lower run of the belt adjacent the drive pulley. A motor drives the roller at a speed so that the surface speed of the roller is greater than the linear speed of the belt to maintain the lower portion of the run of the belt between the roller and the drive pulley under tension. A sweep assembly slidably mounted on the wood deck operates to move the material off of the side of the top run of the belt into the bunk. The sweep assembly has a roller located in driving engagement with the upper run of the belt and an angularly located drum. Coacting drive members drivably connect the roller with the drum so that on rotation of the roller the drum is rotated to move material off the side of the belt. A reversible motor drivably connected with a cable to the sweep assembly operates to reciprocate the sweep assembly between opposite ends of the support. A belt tightening assembly associated with the pulleys maintains the belt under tension. The belt tensioning assembly includes biasing springs and a linear actuator that adjusts the biasing force on the springs to maintain tension on the belt. A diverter assembly attached to the sweep assembly has a pivotally mounted chute movable to opposite inclined positions to selectively direct the material to opposite sides of the feed bunk.

Apparatus for tensioning a belt

A motor vehicle having a pair of front drive wheels and a rear steerable drive wheel mounted on a main frame. A sub-frame secured to the main frame intermediate the front and rear drive wheels carries an internal combustion engine and a pump assembly. The pump assembly has a first pump operable to deliver fluid under pressure to fluid operated motors operably connected to the front drive wheels and a second pump operable to deliver fluid under pressure to a fluid operated motor operably connected to the rear drive wheel. The internal combustion engine and pump assembly are located below a seat and floor with both the engine and pump assembly positioned transversely of the main frame of the vehicle. The rear wheel is mounted on the frame for angular movement about a generally upright axis. A fluid operated double acting piston and cylinder assembly operates to angularly move the rear wheel about the upright axis to steer the vehicle.

Fluid pressure power transmission

A material conveying apparatus having a trough assembly for receiving material connected to a tail section. The tail section has a door movable to an open position to facilitate the cleaning of the tail section. An incline section connects the trough section to an elevator section. The incline section has conveyor guide strips that guide a movable conveyor in an arcuate path to the elevator section. The elevator section is connected to a decline assembly having a wear strip for guiding and supporting the movable conveyor. A discharge section is connected to the decline section. The drive for the movable conveyor is mounted on the discharge section.

Incline-decline conveyor

A top unloading silo unloader pendently supported in a tower silo. The unloader has a material collector moved around the silo with leading and trailing drive wheels. An impeller receives material from the collector and throws the material into an out chute which directs the material to a doorway leading to an upright passageway. The drive wheels are mounted on opposite ends of a rocker arm rotatably supported on a support. The support is connected to the impeller housing. Power is applied to both wheels by separate drive shafts connected to a gear box. A collector leveling apparatus has a linear actuator connected to the unloader frame. A cable connects the linear actuator with the outer end of the collector and the support in a manner so that the outer end of the collector can be raised or lowered and held in a selected position in response to operation of the actuator. The linear actuator has a reversible electric motor coupled to a motor controller. A reference arm attached to the rotating part of the unloader is linked to the controller so that movement of the collector up or down actuates the controller, whereby the motor operates the linear actuator to reduce its overall length to raise the outer end of the collector or to increase its overall length to lower the outer end of the collector thereby maintaining the outer end of the collector at a selected position.

Three wheel drive vehicle

A motor vehicle equipped with lift arms and a bucket for handling material. The vehicle has a fluid power system including piston and cylinder assemblies to pivot the lift arms between down and up positions and tilt the bucket relative to the lift arms. A bucket leveling control apparatus operates a fluid control valve in response to the pivotal movement of the lift arms to control the flow of fluid to the bucket tilting piston and cylinder assembly to maintain the bucket substantially level during the movement thereof between down and up positions. The fluid control valve is operable to supply fluid under pressure to the bucket tilt piston and cylinder assembly to move the bucket to a dump position.

Material conveying apparatus

A top unloading silo unloader pendantly supported in a tower silo. The unloader has a material collector moved around the silo with drive structure. An impeller receives material from the collector and throws the material into an out chute which directs the material to a doorway leading to an upright passageway. The drive structure mounted on the outer end of the collector has leading and trailing drive wheels connected with movable mounts to a leveling apparatus. Power is applied to both wheels by separate drive shafts connected to the power transmission for the augers of the collector. The leveling apparatus has a base secured to the collector. Supports pivotally mounted on opposite ends of the base are attached to the mounts for the wheels. A linear actuator connected to the supports operates to concurrently pivot the supports in opposite directions so that the outer end of the collector can be raised or lowered and held in a selected position. A lost motion connector attaches the linear actuator to one support to allow the linear actuator to have limited contraction without raising the drive wheels. The linear actuator has a reversible electric motor coupled to a motor controller. A generally horizontal reference arm attached to a non-pivoting part of the unloader is linked to the controller so that movement of the collector up or down actuates the controller whereby the motor operates the linear actuator to increase its overall length to raise the outer end of the collector or to decrease its overall length to lower the outer end of the collector thereby maintaining the outer end of the collector at a selected position.
