Abstract

PURPOSE:To prevent grains from staying in a connecting part or the like of a sending-out conveyor by connecting individual motors to respective ones of a scraping-out conveyor and the sending-out conveyor, first driving a motor of the sending-out conveyor when electric power supply is started, and driving a driving motor of the scraping-out conveyor by delaying a short time. CONSTITUTION:A hopper 1 is formed in a cross-sectional almost V shape, and a scraping-out screw 2 is arranged in the longitudinal direction of a bottom part, and the scraping-out screw 2 is driven by a second motor 9 through a power transmission belt. A socket on one side end of a sending-out conveyor 5 is arranged so as to be adjusted to a connecting port 8, and is made adjacent to a connecting side part of the sending-out conveyor 5, and is driven in a directly coupled condition by a first motor 10. When main electric power supply 11 is closed, an electromagnetic contactor is actuated, and the first motor 10 on the sending-out conveyor 5 side rotates. When this electromagnetic contactor is actuated, a time relay is actuated, and for example, after two seconds to five seconds being preset time, another electromagnetic contactor is actuated, and the second motor 9 driving the hopper 1 side scraping-out screw 2 rotates.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyer used for conveying grains such as a grain harvested with a combine in a dryer, and more particularly to a method for driving a conveyor motor.

[0002]

2. Description of the Related Art Various grain transporters have been devised. For example, Japanese Utility Model Publication No. 3-44739 discloses a technique for solving the problem that grains are accumulated at the connecting position of a spring conveyor device by stopping the conveyance on the hopper side by a sensor for accumulated grains and an electromagnetic clutch system.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since two conveyors are driven by individual motors, there is a drawback that the drive mechanism of the connection part of the spring conveyor part for sending out becomes complicated, and at the same time when the grain is unloaded from the hopper at the time of start-up, or when it is unavoidable. This is an idea in view of the problem that grain is stuck in the connecting portion during work and causes a clogging phenomenon.

[0004]

In order to solve the above problems, a scraping conveyor is installed at the bottom of the hopper, and a discharge conveyor is connected to the discharge port of the hopper of this page (2). In a grain transporter in which separate motors are connected to the raking conveyor and the feeding conveyor, the motor of the feeding conveyor is driven first when the power is turned on, and the driving motor of the feeding conveyor is driven after a short delay. The present invention provides a grain conveyor.

[0005]

[Function] The grain transfer machine described above is installed in the dryer room,
When the main power is turned on, first the motor of the feeding conveyor outside the hopper is driven to discharge the grain in the conveyor, and after a short time, the scraping conveyor at the bottom of the hopper is driven and the grain is carried out for feeding. As a result, grain is not accumulated in the connecting portion of the delivery conveyor, and the grain is not clogged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing the flow of the present invention, and FIG. 2 is an electric circuit diagram.

In FIG. 1, reference numeral 1 denotes a hopper having a substantially V-shaped cross section, and a scraping screw 2 is provided in the front-back direction of the bottom portion. Reference numeral 3 denotes a shutter lever, which adjusts the opening of the shutter covering the upper part of the scraping screw 2. A second motor 9 drives the scraping screw 2 described above via a transmission belt. Reference numeral 8 denotes a connecting port opened at the bottom of one side end of the hopper 1, and the receiving port at one side end of the delivery conveyor 5 is aligned with the connecting port 8. The first motor 10 is directly connected and driven so as to be adjacent to the connection side portion of the delivery conveyor 5. Reference numeral 7 denotes a discharge port of the delivery conveyor. In this embodiment, the delivery conveyor 7 is formed of a known spring conveyor and has a bendable structure. A fir sensor 4 detects grain in the hopper 1 to prevent the second motor 9 from idling. Reference numeral 6 is a fir sensor provided inside the discharge port 7 of the delivery conveyor 5, and the first and second motors 1 when the grain becomes full or stays in the receiving port of the dryer room or the like.
0 and 9 stop, and automatically rotate when grain runs out. The page (3) 13 is an operation panel provided with a main power source 11, a manual switch 12, a monitor lamp, etc., and appropriately controls the first motor 10, the second motor 9, and the fir sensors 4 and 6 described above.

Next, the electric circuit diagram of FIG. 2 showing only the main points will be described. When the main power source of 11 is turned on, the electromagnetic contactor of MS1 operates, and the first motor on the side of the delivery conveyor of M1 rotates. When the electromagnetic contactor of MS1 is activated, TR1 of the time relay is activated, and after a set time, 2 to 5 seconds in this embodiment, the electromagnetic contactor of MS2 is activated and the scraping screw 2 on the hopper side is activated. The second motor 9 that drives the motor rotates. Although not shown in the figure, a reverse phase correction relay is incorporated in each motor, and the circuit is configured so as to be automatically switched so as to always rotate in the set direction by detecting the current phase on the power source side.

[0009]

As described above, when the main power is turned on, the feeding conveyor outside the hopper is driven independently first, and then the hopper scraping conveyor is driven, so that the clogging phenomenon of the connecting port is eliminated. It was Further, since the start of the two motors is sent for a short period of time, the operation electromotive force is compressed by being phased, so that there is an effect that the load of facility power is lightened.
