Description

  The present invention relates to a grain container that is mounted on a truck or the like and used to transport harvested and harvested grains such as rice and wheat to a home or a predetermined processing facility (a destination such as a rice center). In particular, it is configured to be folded by removing a part of the frame material constituting the machine frame that is configured in a substantially rectangular shape in plan view in order to suspend the storage tank formed using the sheet material inside. Related to grain containers.

  A storage tank formed in a substantially funnel shape using a sheet material is attached in a suspended manner inside a machine frame that is configured in a substantially rectangular shape in plan view, and harvested rice, wheat, etc. A grain container configured to store grain in a storage tank and transport it to a home or a predetermined processing facility (such as a rice center) by a truck or the like is known (see Patent Document 1).

By the way, the grain container is mounted and used on a truck bed or the like only during the grain harvesting period, and is unloaded from the truck and stored in a storage place such as a warehouse in other periods.
Japanese Patent Laying-Open No. 2005-22742 (see paragraph numbers 0024, 0027, 0038 and FIG. 6)

However, the conventional grain container disclosed in Patent Document 1 is a connecting bracket attached to each column frame at the four corners at the frame end of the beam, which is a horizontal frame for suspending the storage tank. It is connected to a certain groove member by pinning or bolting.
For this reason, when removing the horizontal frame from between the support frames when removing the grain containers in a compact storage place such as a warehouse, remove the pins and bolts from the connection brackets of each support frame one by one. It had to be cumbersome and time consuming.
In addition, there is a problem that the pins and bolts removed from the connection fitting may be lost when the grain container is moved (conveyed) to the storage location or stored.

  Therefore, the present invention has been created to solve the above-mentioned problems, and the frame end of the horizontal frame is detachably connected to the four-corner support column frame constituting the machine frame by a simple operation. An object of the present invention is to provide a grain container having a new connection structure developed so that it can be made.

In order to solve the above-mentioned problems, in the present invention, a storage tank formed in the upper opening by a sheet material, a machine frame for suspending the storage tank, and a swingable rotation on the base part of the machine frame A feeder installed on the storage tank, wherein the grain stored in the storage tank is connected to the lower opening of the storage tank, and the stored grain is sent out of the tank. The frame includes each column frame standing at the four corners, and a horizontal frame that is framed in a substantially rectangular shape in plan view between the column frames and suspends the storage tank. A cereal container configured to be folded by removing at least a portion thereof from between the strut frames,
A frame end portion of the horizontal frame is configured to be detachably coupled to a coupling bracket attached to each column frame via a coupling mechanism, and the coupling bracket is substantially the same as the cross-sectional shape of the horizontal frame. A frame connecting portion formed in a substantially U-shape in a cross-sectional view opening toward the inside of the machine frame is provided (Claim 1).

According to the structure of Claim 1, the frame edge part of the horizontal frame attached ranging between each support | pillar frame of a four corner corner is fitted and incorporated in the frame connection part of the connection metal fitting opened toward the inner side of a machine frame. In this state, the connection mechanism can be connected so as not to be disengaged (detached).
In other words, the storage tank delivery device is configured so that the horizontal frame for suspending the storage tank can be connected from the inside of the machine frame to the frame connecting portion of the connecting bracket of each support frame. The storage tank can be attached and suspended in the machine frame in a state in which the range from the lower opening connected to the upper opening to the horizontal frame is tensioned. As a result, when the stored grain is sent out of the tank and discharged, the grain can be quickly flowed down to the feeder and sent out of the tank.

  Further, in the present invention, the frame coupling portion of the coupling bracket includes a pin insertion hole opened coaxially with a pin coupling hole opened at the frame end of the horizontal frame, and the coupling mechanism includes the pin A connection pin that is attached to the connection fitting so as to protrude into and out of the frame connection portion on the axial extension line of the insertion hole, and is inserted in a penetrating manner from the pin insertion hole to the pin connection hole, and the connection pin is connected to the pin And a resilient member for always urging in the direction of the insertion hole.

  According to the configuration of the second aspect, the horizontal frame is connected to and released from the frame connecting portion of the connecting bracket of each support frame, and the connecting pin of the connecting mechanism is moved from the pin insertion hole to the pin connecting hole by the resilient member. It can be carried out by a simple operation such as inserting the connecting pin in a penetrating manner or pulling the connecting pin against the elastic member. In addition, since the connection pin is attached to the connection metal fitting so as to protrude into and out of the frame connection portion, there is no possibility that the grain container is lost during storage or during storage.

  Further, in the present invention, the movable member is rotatably attached to the coupling metal so that the coupling mechanism closes a part or the whole of the inward opening of the frame coupling part of the coupling metal, and the movable member In a state in which the inward opening is closed, and a locking portion for releasably locking the locking claw portion formed on the movable member. (Claim 3).

  According to the configuration of the third aspect, the horizontal frame can be connected to and disconnected from the frame connecting portion of the connecting bracket of each support frame by a simple operation such as rotating the movable member of the connecting mechanism. it can. In addition, since the rotating member is attached to the connecting metal fitting, there is no fear that it will be lost as in the second aspect.

The grain container according to the present invention is configured as described above, so that the grain in the storage tank formed of the sheet material is sent out of the tank and discharged without leaving the grain. Can do.
In addition, the horizontal frame can be connected to and disconnected from the frame connecting portion that opens inwardly of the connecting bracket attached to each column frame at the corners of the four corners by operating the connecting pin of the connecting mechanism. Therefore, when folding the machine frame compactly, or when disassembling the machine frame and putting it together compactly, and when assembling the machine frame at the grain harvest time, the horizontal frame can be attached to and detached from each support frame. Can be done with simple operation. Thereby, the handleability is improved.
Moreover, there is no risk of losing pins or the like as in conventional containers.
