[Prior art]
2. Description of the Related Art Conventionally, a grain conveyor having a flow conveyor that is configured by horizontally suspending a flight chain having a large number of conveying blades between a driving sprocket and a driven sprocket respectively provided at one end and the other end of a grain conveying basket. in the grain remaining on the flight chains that as drop sweep the brush strip is described in JP 62-23511 1 JP.
[0003]
Japanese Patent Application Laid-Open No. 8-40534 discloses a method in which grain remaining on a flight chain is removed by blowing a compressed air.
[0004]
[Problems to be solved by the invention]
This type of grain transporter transports the grain supplied from the grain supply unit of the grain transporter to the grain discharge side of the grain transporter by the rotation of the flight chain provided with a number of transport blades. Part of the grain being transported remains on the flight chain and must be removed. However, as those described in JP 62-23511 1 JP supra, are those having a brush strip in contact with the top of the flight chain, the turning point unit flight chain rotates and passes through the brush pieces Each time the brush piece is rebounded, the brush piece is intermittently separated from the flight chain, and the grain on the flight chain remains without being removed.
[0005]
Further, as described in the above-mentioned Japanese Patent Application Laid-Open No. 8-40534, when the residual grain is blown off by blowing the compressed air, the surrounding grains are also blown up. There is a fault that remains on top.
[0006]
The present invention is for an object to overcome the disadvantages of those of the prior, not generated the rebound of the brush body with the rotation of the flight chain, shake off remaining grain on the fly DOO chain However, it is possible to remove the residual grain on the flight chain by pressing the brush body on the flight chain while maintaining an appropriate pressure contact state, and when the grain outlet shutter is closed, the brush body The present invention provides a residual grain removing device in a grain transporter that can eliminate unnecessary wear of the brush part by separating the brush part from the flight chain .
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a residual grain removing apparatus in a grain conveyor according to the present invention includes a large number of conveying blades between a drive sprocket and a driven sprocket provided respectively at one end and the other end of a grain conveying basket. In a grain conveyor configured by suspending a flight chain horizontally to form a flow conveyor, the grain outlet of the flow conveyor has a shutter that opens and closes it, and remains on the flight chain in correspondence with this grain outlet. A brush body that sweeps away the grains to be removed is provided, and this brush body is a brush plate having a brush portion that is in contact with the flight chain, and the brush plate is configured to elastically bias the brush plate in a direction in which the brush portion is in pressure contact with the flight chain. Is.
[0008]
In the present invention, in the above configuration, the brush body is interlocked with the open / close air cylinder of the shutter by the interlocking link mechanism. When the shutter is opened, the brush portion is pressed against the flight chain, and when the shutter is closed, the brush portion is in flight. It is configured to be separated from the chain.

DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of the present invention, FIG. 1 is a schematic view of a grain preparation facility using a grain transporter according to the present invention, and FIG. 2 is a partial side view showing a residual grain removing apparatus according to the present invention. 3 is a schematic front view of a portion corresponding to FIG. 2, and FIG. 4 is a plan view showing a part of the flight chain.
[0010]
In FIG. 1, reference numeral 1 denotes a grain conveyor according to the present invention. The grain conveyor 1 hangs a flight chain 6 having a large number of conveying blades 5 between a driving sprocket 3 at one end of a grain conveying basket 2 installed horizontally and a driven sprocket 4 at the other end. A flow conveyor is configured. Reference numeral 7 denotes a plurality of grain outlets, and each grain outlet 7 is provided with a shutter 8 for opening and closing it. 9 is a grain tank and 10 is a grain supply device. The grain conveyor 1 is for carrying grains into and out of the grain storage tank 9. Incidentally, grain conveyor 1 according to the present invention is also used to carry the grain to grain dryers (not shown).
[0011]
As shown in FIGS. 2 and 3, the grain conveyor 1 is provided with a brush body 11 that sweeps away grains remaining on the flight chain 6 in correspondence with each grain outlet 7. Is formed of a brush plate 13 having a brush portion 12 in contact with the flight chain 6, and the brush plate 13 is attached to the support plate 15 via a spring hinge 14 that is elastically biased in a direction in which the brush portion 12 is pressed against the flight chain 6. The support plate 15 is connected to a fixed portion 17 of the flow conveyor by a support shaft 16. The brush body 11 can be displaced from the state in which the brush portion 12 is pressed onto the flight chain 6 by rotating about the support shaft 16.
[0012]
The brush body 11 that sweeps away the grains remaining on the flight chain 6 is linked to the open / close air cylinder 18 of the shutter 8 that opens and closes the grain discharge port 7, and the brush of the brush body 11 only when the shutter 8 is opened. When the shutter 12 is closed when the part 12 comes into pressure contact with the flight chain 6, the brush part 12 of the brush body 11 is separated from the flight chain 6. Reference numeral 19 denotes the interlocking link mechanism.
[0013]
As shown in FIG. 4, the brush body 11 has a width that is equal to or slightly wider than the width L of the flight chain 6 and the transport blade 5 that is fixed to the flight chain 6 and protrudes left and right in the transport direction. Therefore, the brush portion 12 of the brush body 11 according to the present invention has a wide width. However, the brush portion 12 is elastically biased toward the flight chain 6 as a whole, and the brush portion 12 is also a flight chain. 6 and the left and right sides of the conveying wings 5 have different deflections depending on the state of the flight chain 6 and the conveying wings 5 due to the pressure by the elastic force and the partially different bending of the brush portion 12. As a whole, the pressure is in a proper pressure state for sweeping off the grains remaining on them, and the residual grains are surely removed, and the brush portion 12 is not excessively pressed.
[0014]
Further, when the shutter 8 of the grain discharge port 7 is closed, the brush portion 12 of the brush body 11 is separated from the flight chain 6, so that unnecessary wear of the brush portion 12 can be eliminated.
[0015]
The brush portion 12 of the brush body 11 is elastically biased in the direction of the flight chain 6 by the elasticity of the spring hinge 14, but the brush body 11 continues to rebound as the flight chain 6 rotates. In order to keep the brush portion 12 away from the flight chain 6, it is necessary that the brush body 11 does not resonate with the vibration of the flight chain 6. On the other hand, it is desirable that the pressure contact force of the brush portion 12 of the brush body 11 with respect to the flight chain 6 is as small as possible in order to reduce wear of the brush portion 12. Therefore, the elasticity of the spring hinge 14 is set so as to satisfy both requirements.
[0016]
【The invention's effect】
According to the present invention, the brush body does not rebound with the rotation of the flight chain, and the brush body is pressed onto the flight chain while maintaining an appropriate pressure contact state for removing residual grains on the flight chain, Residual grain on the flight chain can be removed reliably, and when the shutter of the grain outlet is closed, the brush part of the brush body is separated from the flight chain , eliminating unnecessary wear of the brush part. The effect which can be done is acquired.
