Conveyer with function of automatic feed adjustment

The utility model discloses a conveyer with a function of automatic feed adjustment. A triangular support is hinged to a large frame through a support pin. A carrier plate is in moving fit with an adjusting groove arranged in the tail end of the large frame through a guide post. The carrier plate is provided with weights. A supporting rack which a discharge hopper is fixed to is integrally fixedly connected to the triangular support. An outlet of the discharge hopper is communicated with a conveying belt. A driving wheel and a driven wheel are disposed on the large frame on two sides of the support pin; the driving wheel and the driven wheel are connected together through the conveying belt. The driving wheel is connected with a spindle of a motor. A fixing rod is hinged to fixing pins fixed on two sides of the discharge hopper; one end of the fixing rod is perpendicularly connected with an adjusting retainer facing the outlet of the discharge hopper; the other end of the fixing rod is hinged to a rocker through a connecting pin; the tail end of the rocker is hinged to the large frame through a moving pin. According to the gravity principle and the lever principle, by the use of the mechanical structure, feed quantity is automatically adjusted; the conveyer is simple in structure and lower in manufacturing cost and needs fewer manual operations.
