[Industrial applications]

 According to the present invention, a screw type grain conveying device is provided at the bottom of a Glen tank, and the grain is transferred to the screw type grain conveying device while receiving the weight of the grain above the screw type grain conveying device. Of the grain tank, which is provided with a grain guide tool for guiding down the grain, and which is provided with a grain unloading device for unloading the transported grain to the outside of the grain tank at the transport end portion of the screw type grain transport device. The present invention relates to a grain export mechanism.

[0002]

[Prior Art]

 Conventionally, as a grain carrying-out mechanism of this type of grain tank, for example, as disclosed in Japanese Utility Model Laid-Open No. 3-50839, the grain transport mechanism is simply located above the screw type grain transporting device in the grain tank. A structure in which a guide tool is arranged is known.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional structure, a grain flow path is formed between the grain guide and the bottom wall or side wall of the grain tank. After the grain is harvested and threshed, the grains adhering to the surface of the grains are likely to solidify due to the moisture adhering to the surface of the grains. There was a problem that the lumps became bridged in the downflow route and became clogged, making it impossible to carry out the grains. Therefore, in order to solve the above-mentioned problems, it has been proposed to provide a mechanism for agitating the grains in the grain tank and to constantly drive the agitating mechanism. However, if the stirring mechanism is constantly driven as described above, unjustified external force is likely to be applied to the grain, and there is a high possibility of damaging the grain, and the power for driving the stirring mechanism is increased. As a result, there is a drawback that labor saving cannot be achieved. The present invention has been made in view of the above circumstances, and stirs the grains in the grain tank so as to clear the clogging only when the grain is in a clogging state where it does not flow down to the screw type grain conveying device. The purpose is to provide a grain unloading mechanism for a Glen tank.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the grain tank unloading mechanism of the Glen tank according to the present invention has the above-described structure, and the grain unloading device is provided with a detection means for detecting the presence or absence of the transported grain. The screw-type grain conveying device is provided with a grain flow-down assisting means for collapsing the grain in order to smooth the flow of the grain to the screw-type grain conveying device, and the screw-type grain conveying device and the grain discharging device are operated. It is characterized in that a control means is provided for activating the grain flow-down assisting means based on the detection result of the non-conveying state of the grain by the detecting means in the state. The actions and effects of this characteristic configuration are as follows.

[0005]

[Action]

 That is, when the grain is blocked due to the cross-linking phenomenon of the grain, the grain will not flow down to the screw-type grain conveying device, so that the detecting means of the grain conveying device does not convey the grain. The condition will be detected. When this non-conveying state of the grain is detected when the screw type grain conveying device and the grain conveying device are in the conveying operating state, the grain flow assisting means is activated, and the crosslinked grains are loosened. As a result, the loosened grains start to flow down to the screw type grain conveying device, and when the grains are conveyed and the detecting device of the grain discharging device detects the state of conveying the grains, the grain flow down compensation is performed. The operation of the auxiliary means can be stopped.

[0006]

[Effect of the device]

 Therefore, since the grain flow assisting means is activated only when the grain is clogged, the driving of the device for eliminating the clogging can be saved and the grain is damaged by the assisting means for eliminating the clogging. It came to be suppressed.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a Glen tank 1 mounted on a combine. The grain tank 1 is arranged in parallel with the threshing device 2 in the machine body, and the grain after being threshed by the threshing device 2 is supplied by the lifting device 3 and stored. At the bottom of the grain tank, a screw type grain conveying device 4 is arranged so as to convey the grains rearward along the front-rear direction. The conveying end of the screw-type grain conveying device 4 extends rearward from the opening of the rear side wall of the Glen tank 1, and the extending end is a grain conveying device including a screw installed in a cylindrical case. The unloader device 5 is linked and linked. The unloader device 5 is constructed such that it can be bent in the middle, and a grain discharge port 6 is provided at the end of the bent tip end portion 5a.

As shown in FIG. 1 and FIG. 2, the portion directly above the screw type grain conveying device 4 receives the weight of the stored grains and the left and right edges of the grains and the slope of the glen tank 1. Grain flow-down paths a, a are formed between the grain flow path and the bottom surface, and a mountain-shaped grain guide tool 7 is installed to guide the grain to the grain flow-down paths a, a. In this grain guide tool 7, front and rear supporting shafts 8 connected to the front and rear ends of the mountain-shaped top are pivotally attached to the front and rear walls of the Glen tank 1, and An electric motor 9 is interlockingly connected to the front-rear supporting shaft 8 extending in one direction. The electric motor 9 is connected to a control circuit 10 as control means. Here, the grain guide tool 7 is vertically driven by an electric motor 9 controlled by the control circuit 10 about the pivot point of the front-rear supporting shaft 8, and by this swing drive, A grain flow assisting means A for stirring the grains near the flow-down paths a and a is configured.

Further, as shown in FIG. 1, a grain presence / absence sensor 11 as a detection means that is switched by the discharged grain is arranged at the grain discharge port 6 of the unloader device 5. At the same time, the grain presence / absence sensor 11 is also connected to the control circuit 10. Further, a detector 12 for detecting an operating state of a clutch (not shown) for connecting and disconnecting the transmission to the screw type grain conveying device 4 and the unloader device 5 is also connected to the control circuit 10.

The control circuit 10 inputs the detection signal of the detector 12 which detects that the screw type grain conveying device 4 and the unloader device 5 are in the driving state with the clutch engaged, When the grain presence / absence sensor 11 detects that the grain is discharged, the guide tool 7 is set to have the same width on the left and right downflow paths a based on the detection result of the grain presence / absence sensor 11. The electric motor 9 is stopped so that it is stopped and fixed in the following posture, and when it is detected that the grain is not discharged by the grain presence sensor 11, the grain presence sensor 11 Based on the detection result, the electric guide motor 7 is configured to drive the electric motor 9 so as to be oscillated around the axis of the support shaft 8 facing forward and backward. Even if the grain presence / absence sensor 11 detects a grain non-existence state, the control is delayed so that the electric motor 9 is not driven until the state does not continue until a certain period of time elapses. Judgment of whether the grain is not transported due to clogging of the grain or discharge of the stored grain from the grain tank 1 or the state where the grain is intermittently transported due to being transported by the screw is not transported. I am making

The present invention may be implemented as follows. (B) The detection means should be provided at a position other than the grain discharge port of the grain carry-out device. (B) A structure as a dedicated grain flow-down assisting means that can stir the grain near the flow-down path so as to assist the grain flow-down without also using the grain guider as the grain flow-down support means.
