Material Spreader Utilizing Vehicle Power And Having Operational Wireless Control

摘要

A material spreader assembly for the broadcast spreading of particulate material from the trailer hitch of a vehicle. A hopper for storing the particulate material is supported by a frame having a trailer hitch coupler for connection to the vehicle. A spreader including a spinner driven by an electric motor receives and disperses the particulate material. A control circuit receives electric current from the vehicle via a plug interface and a wiring harness and controls the operation of the spreader. A remote communicates user commands to the control circuit. The control circuit includes a motor control processor that controls a motor power relay and a motor driver to gradually ramp up the current supplied to the spreader for start up the spreader while preventing a high transient current draw spike. Component feedback sensors enable the motor control processor to provide an emergency shut off feature and warning signals.

1. A material spreader assembly for broadcast spreading of particulate material from a vehicle having a trailer wiring connector supplying electrical current below a predetermined level comprising;
a frame, a hopper supported by said frame for storing particulate material, a spreader powered by electrical current including at least one rotating component for receiving and dispersing said particulate material from said hopper and an electric motor connected to said rotating component for rotationally driving said rotating component, a coupler connected to said frame and supporting said frame on the vehicle, a wiring harness presenting a plug interface configured to detachably engage a trailer wiring connector of a vehicle to receive electrical current therefrom, a wireless remote having an ON selection and an OFF selection to generate and wirelessly send an ON signal communicating said ON selection and an OFF signal communicating said OFF selection and an incremental motor speed selection configured to generate and wirelessly send a motor speed signal communicating said incremental motor speed selection, a control circuit including a motor control processor configured to provide start-up of said electric motor in response to said ON signal and generate a power ON command corresponding with said ON selection and generate at least one motor speed command and provide shut-off of said electric motor in response to said OFF signal and generate a power OFF command corresponding to said OFF selection and provide motor speed control in response to said motor speed signal and generate said motor speed command to correspond with said incremental motor speed selection, and said remote having a radio frequency transmitter housed within said remote transmitting said ON signal and said OFF signal and said control circuit including a radio frequency receiver receiving said ON signal and said OFF signal transmitted by said radio frequency transmitter of said remote and sending said ON signal and said OFF signal to said motor control processor.
