Multi-path material discharger and operation speed control method thereof

Abstract

The invention discloses a multi-path material discharger and an operation speed control method thereof. The multi-path material discharger comprises a machine case and a material guiding-out structure, wherein a material distributing structure and a plurality of material discharging passages are arranged in the machine case; the material distributing structure is controlled by a motor to operate;the material guiding-out structure comprises an intercepting unit, and the intercepting unit can be switched between an idle state and an intercepting state; in the idle state, the materials can falldown from the material discharging passages to be thrown to a target position; and in the intercepting state, the intercepting unit intercepts all of the material discharging passages and guides materials passing through the material discharging passages out of each material discharging passage. The intercepting unit is controlled to be switched to the intercepting state; the materials dischargedfrom the material discharging passages can be directly intercepted and guided out to be collected and metered in a unified mode; the circulation path of the materials is short; and the loss is little;and the calibration precision can be improved. The operation speed control method of the multi-path material discharger is based on the calibrated material discharging amount value; the rotating speed of the motor can be adjusted in real time; and agricultural materials can be uniformly spread.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a multi-way discharger and a method for controlling its operating speed. Background technique [0002] Agricultural farming machinery can perform automatic seeding and fertilization operations. Agricultural farming machinery is generally equipped with a discharger for distributing agricultural materials such as seeds and fertilizers. For multi-channel tillage and sowing operations, the discharger included is a multi-channel discharger that can simultaneously feed multiple broadcasting mechanisms. [0003] Due to the different characteristics of various seeds or fertilizers, the amount of seeds or fertilizers discharged by the multi-way discharger in the same cycle is also different. Therefore, the overall discharge of the multi-way discharger is required before the agricultural tillage and sowing machinery enters the land. The amount is calibrated to facilitate th...

Problems solved by technology

[0004] In the existing agricultural farming machinery, when calibrating the overall discharge volume of the multi-channel discharger, the general method is: control the operation of the multi-channel discharger to set the cycle, and then calibrate the end of each feeding path of the multi-channel spreading mechanism. The materials that come out are collected to determine the overall output volume of the multi-channel discharger in one cycle. This calibration method is very troublesome for the collection of materials. After the feeding path, the loss may be large, the operation is troublesome and the calibration value obtained may be inaccurate
