Description

TECHNICAL FIELD The present invention relates to a trial run device for an agricultural machine such as a grain dryer or a paddy sorting machine.

[Problems to be Solved by Prior Art and Invention] Conventionally, the above-mentioned agricultural machines generally do not have a test operation device for confirming the operation of each part before operation, or operate a special test operation switch. There is a configuration that is installed on the board surface and switches the device to the trial operation mode.

However, in the above-described configuration in which the special test operation switch is provided, the switch must be additionally set on the operation panel surface, and the configuration is complicated.

[Means for Solving the Problem] The present invention is intended to simplify the configuration by using an existing switch as a trial run switch and to simplify the configuration. A start switch and a stop switch of a motor or the like for driving various rotating parts on an operation panel. In addition, in an agricultural machine equipped with an adjustment / changeover switch,
Trial operation mode transition operation means for entering and operating any one of the existing adjustment / changeover switches and the start switch together, and any one of the existing adjustment / changeover switches and the stop switch And a trial operation mode end operation means for terminating the trial operation mode by turning on and off.

[Operation and effect of the invention] Before starting this work in advance, one of the existing adjustment / selection switches and the start switch are both turned on and the trial operation mode transition operation means is operated to switch to the trial operation mode. Next, the trial run operation of each part is performed, and when the trial run operation ends, one of the existing adjustment / changeover switches and the stop switch are operated together to operate the trial run mode end operation means to end the trial run mode. . The operator can grasp the abnormality and normal state of each part of the machine by this test operation state, and the trouble can be reduced during the main work.

In addition, since the switching to / from the trial run mode is performed by a combination of the existing adjustment / changeover switches and the operation of the start switch and the stop switch, it is not necessary to provide a special trial run switch on the operation panel surface, and the configuration can be changed. Can be simplified.

The output of the removal rate sensor 19 is set to the rotary switch 47.
The control motor 4 is switched to the so-called loss ratio control in which the control motor 4 is interlocked with the normal and reverse so as to match the set loss ratio while comparing with the set value (for example, the loss ratio of 85%).

The rotation control of the rotation selection cylinder 20 is performed by the rotation speed detection sensor 41.
It is possible to compare the detection result of 1) with the set rotation speed (for example, 50 rpm) of the rotary switch 48, and to interlock the rotation speed control motor 31 in the forward and reverse directions to always keep the set rotation speed constant.

By turning on both the buzzer stop switch 46 and the start push button switch 44, the control section in the operation panel 42 is switched to the trial operation mode, and a series of trial operation operations can be performed. The trial run mode is terminated by turning on the push button switch 45 for stopping the motor 43.

The operation of the above example will be described.

When the buzzer stop switch 46 and the start push button switch 44 are both turned “ON” at the start of paddy sorting work,
The test operation mode is entered, and the above-mentioned operations 1 to 3 are performed before the paddy is supplied, and the operator can confirm whether the operating states of the respective parts are normal or not. In this way, it is judged that the normal operation is possible by the trial operation of each part, the stop push button switch 45 is turned "ON" to stop the trial operation, and the main work is started.

When paddy is fed to the feeding funnel 2, the paddy is derolled 3,3
The mixed rice, which is removed while passing through the space and subjected to the wind separation treatment, is passed through the mixed rice guide tube 28, the mixed rice transfer gutter 21 and the like to the sorting cylinder 20.
Supplied within.

The sorting cylinder 20 scoops the mixed rice in the pot holes 23, 23, the brown rice passes through the finishing valve 29 and is collected in the finishing rice gutter 22, and the long grain paddy has a high center of gravity and a relatively low pot. Dropped into the mixed rice layer. The above-mentioned selection is repeated from the starting end side to the terminating end side of the selection tube 20 to separate into paddy and brown rice. The brown rice is taken out of the machine through the receiving gutter 33, the brown rice gutter 34, the grain elevator 36 and the like.

Moreover, the paddy (including some brown rice) remaining on the terminal end of the sorting cylinder 20 is
It is scooped by the fried feathers 37, 37 and flows down to the opening 40 side.
The grain that has passed through the opening 40 is returned to the second part of the feeding funnel, and again removed and subjected to the wind separation treatment.

During the above work, the detection result of the escape rate sensor 19 and the set value are compared so that the set escape rate is reached, or the detection result and the set value of the rotation speed detection sensor 41 are set so that the rotation speed of the sorting cylinder 20 is also at the set rotation speed. Are compared.

Further, when an abnormality such as overload detection of the motor 43 by the current transformer 52, no paddy detection in the supply funnel 2 by the grain presence / absence sensor 9, deployment detection by the roll deployment sensor 11, etc. occurs, the corresponding LEDs 50, 50 ... At the same time, a buzzer sounds to alert the operator.

The trial operation of the present embodiment has been described in the case of a hulling and sorting machine, but it can also be carried out with a grain dryer, for example. In this case, the buzzer stop switch that notifies poor paddy flow, motor overload, burner abnormality, etc., and the start-up switches for drying, discharging, and discharging are simultaneously set to "O".
It is advisable to perform “N” and perform a trial run of each work before starting this work.
