<p>An improved soil feeder system in combination with a soil separating apparatus and method of controlling the feeding of soil material employing the soil feeder. The soil feeder apparatus includes a hopper body (28) to receive soil material and an opening (38) at one end for controlling the feeding of soil material to be screened. The body includes hydraulic cylinders (46) at the one end to tilt the hopper body between a soil receiving position and a tilted soil discharging position. An interruption system is provided to cause a series of abrupt interruptions in the tilting of the hopper body. The interruption system includes a cycle timer (TR-1) which controls the period of time between the start of each interruption and an interruption timer which controls the length of time of each interruption. The interruption is caused by a sudden and temporary diversion of hydraulic fluid from the hydraulic cylinders which tilt the hopper body. The interruption imparts a thump or inertial shock to the soil on the hopper body, thereby deconsolidating the soil and allowing it to flow more consistently.</p> |
