An automatic control system for a baler

Abstract

The invention provides an automatic control system of a bundling machine. The automatic control system comprises a feeding control system, a compression control system, a net releasing control system,an unloading control system, a microprocessor and a display device. The feeding control system is used for controlling the walking speed according to the change of the feeding amount and is divided into three modules, namely a signal acquisition module, a single chip microcomputer module and a hydraulic driving module; the signal acquisition module comprises a pressure sensor and a speed sensor;the hydraulic driving module comprises a walking continuously variable transmission, an electromagnetic valve and a hydraulic oil cylinder; the compression control system is used for uninterruptedly compressing forage entering the compression chamber and taking pressure judgment or volume judgment as a judgment standard for compression completion, and the net releasing control system is used for releasing a net into the compression chamber of the bundling machine and cutting off a net rope by using a net knife; and the unloading control system controls the bundling machine to open and close the compression chamber, and the bundling process of the next period is continued.

Description

Technical field: [0001] The invention is used in the technical field of round bale balers, and in particular relates to an automatic control system of a baler. Background technique [0002] Up to now, because a series of operations of bale forming have not been fully automated, a large number of manual interventions by operators are required each time. Therefore, irregular operations when winding the net after bale forming will increase the waiting time of the operation. , making the bale unloading time and the baling cycle longer. However, the overall degree of automation of our country's balers is not high. In the actual use process, if we want to achieve efficient baling, we must require the bale driver to have sufficient work experience. The machine has the following three problems in actual use: [0003] 1) Whether the bale pressure can reach the preset value is mainly judged by the operator observing the oil pressure gauge on the tractor. Usually, the bale pressure w...

Problems solved by technology

However, the oil pressure is not easy to control. If the oil pressure is too high, the tractor will be overloaded or even extinguished. If it is too small, the quality of the bale will be unqualified.

Therefore, the whole trimming process has higher requirements on the operator.

[0004] 2) In the process of tying the bales, there are problems that the tying is not tight, the distance between the tying ropes cannot be flexibly controlled, and the replacement of the baling ropes is cumbersome.

Most of the bales that are bundled out in this way are of substandard quality, and the work efficiency is poor.

[0005] 3) The number of bales cannot be efficiently recorded and saved
