[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a storage unit for temporarily storing a processing object received and conveyed by a receiving unit, and a separation unit for separating the processing object supplied from the storage unit into an object with a branch and a measurement object. The present invention also relates to a receiving unit in a grain processing facility, which is configured by assembling unit units in which measuring units for measuring the object to be measured are arranged in the vertical direction.
[0002]
[Prior art]
As described above, the receiving unit in the grain processing facility having the above configuration reduces the area occupied on the installation surface by configuring each of the storage unit, the sorting unit, and the weighing unit by vertically arranging them in a unit shape. Although it can be installed in a state where it has been set, in a receiving processing unit having such a configuration, conventionally, a re-threshing target object with branch spikes that has been sorted and discharged by the sorting unit has been conventionally used. As described above, the threshing machine is configured to be installed on the installation surface separately from the storage unit, the sorting unit, and the weighing unit that are assembled in a unit shape in the vertical direction as described above.
[0003]
[Problems to be solved by the invention]
In the above conventional configuration, since the re-threshing machine is configured to be installed on the installation surface separately from the storage unit, the sorting unit, and the weighing unit assembled in a unit shape, A dedicated installation space for installation is required, and there is a disadvantage that the installation space for installing the receiving unit is large, and the separation unit and the threshing machine are located apart from each other. A large-scale transport device is required as a transport device for transporting the selected objects with branch spikes to the re-threshing machine, which disadvantageously complicates the configuration of the load receiving processing unit.
[0004]
The present invention has been made in view of such a point, and an object of the present invention is to provide a cargo receiving processing unit in a grain processing facility capable of solving the above-described disadvantages, saving space and simplifying the configuration. Is to do.
[0005]
[Means for Solving the Problems]
A receiving section in the grain processing equipment according to claim 1, wherein the receiving section temporarily stores the processing object received and conveyed by the receiving section, and a processing object supplied from the storing section is a branching target. A sorting unit that sorts the objects and the objects to be weighed, and each of the weighing units that weighs the objects to be weighed is arranged and assembled in a unit shape in a vertical direction, and the sorting unit includes A re-threshing machine for re-threshing the object with a branch spike that has been selected and discharged is assembled together with the storage unit, the selection unit, and the measuring unit in a unit shape.
[0006]
That is, the storage unit, the sorting unit, and the measuring unit are arranged in a vertical direction and assembled into a unit. Since the storage unit, the sorting unit, and the weighing unit are assembled in a unit shape, the storage unit, the sorting unit, and the weighing unit are assembled in a unit shape by vertically arranging each of the units. The processing area can be installed in the same installation space as the installation space when the threshing machine is installed separately from those on the installation surface. Becomes possible. In addition, the re-threshing machine is located at a position close to the sorting unit, and the distance between the re-threshing machine and the sorting unit is shortened. A transfer device having a small and simple configuration can be used as a transfer device for transferring a sheet.
[0007]
Therefore, it is possible to reduce the installation space for installing the storage unit, the sorting unit, the weighing unit, and the threshing machine, thereby saving space. By using a small and simple transport device as a transport device for transporting articles to a re-threshing machine, it has become possible to provide a cargo receiving processing unit in a grain processing facility capable of simplifying the configuration. .
[0008]
The receipt processing unit in the grain processing equipment according to claim 2, wherein the storage unit and the storage unit, which are located above the measuring unit, in the framework frame provided around the measuring unit in claim 1, It is configured to support the load of the sorting unit, and the re-threshing machine is assembled to a gantry connected to the framework frame, and the object with branch spikes selected by the sorting unit is provided to the re-threshing machine. It is characterized in that a receiving guide route for guiding in a state of natural fall is provided.
[0009]
In the lowermost weighing unit among the above-mentioned units assembled in a unit, it is necessary to support the load of the storage unit and the sorting unit located on the upper side, but they are only supported by the members constituting the weighing unit. If the load is supported, the weighing section itself must have high rigidity, which is disadvantageous in that the cost increases. Thus, the rigidity of the weighing unit itself is reduced by using the frame provided around the weighing unit as a strength member and supporting the load of the storage unit and the sorting unit located above the weighing unit. The load can be supported without increasing. Then, a frame is connected to the frame using the frame, which is a strength member, and a re-threshing machine is mounted on the frame to support the load of the re-threshing machine.
[0010]
Since the framework frame is provided so as to surround the periphery of the weighing unit, the re-threshing machine assembled to the gantry connected to the framework frame is located below the sorting unit. Then, the target with branch spikes selected by the selection unit is guided by the re-threshing machine through the receiving guide path in a state of being naturally dropped.
[0011]
Therefore, it is possible to support the re-threshing machine using the configuration for supporting the load of the storage unit and the sorting unit, and to complicate the configuration such as providing a dedicated support frame for supporting the re-threshing machine. In addition, as a configuration for transporting the object with branch spikes selected by the sorting unit to the re-threshing machine, a receiving guide path for allowing the object with branch spikes to fall naturally into the re-threshing machine And a simple configuration such as a cylindrical body can be used, and the configuration of the receiving unit can be simplified.
[0012]
According to a third aspect of the present invention, there is provided a grain processing facility according to the first or second aspect, wherein the object to be processed, which is measured and dropped and supplied by the weighing unit, is received at a transport start end and lifted to a transfer position. A discharge guide path that is provided with a lifting transport conveyor that transports upward, and guides the processing target rethreshed by the re-threshing machine in a state of being naturally dropped toward the transport start end of the lifting transport conveyor. Is provided.
[0013]
In other words, the object to be processed, which has been sorted as the object to be weighed by the sorting unit and weighed by the weighing unit, is lifted and conveyed to the transfer position by the hoisting conveyor and transferred to the next process. become. In addition, the processing object that has been sorted as a target with a branch in the sorting unit and re-threshed in the re-threshing machine naturally falls toward the transport start end of the lifting transport conveyor through the discharge guide path. . Then, it is lifted and transported to the transfer position by the lifting transport conveyor and transported to the next process.
[0014]
Not only the processing target discharged from the weighing unit as described above, but also the processing target rethreshed by the rethreshing machine, is configured to fall naturally toward the transport start end of the lifting transport conveyor, As a configuration for transporting the processing target, any configuration may be used as long as it constitutes a discharge guide path that guides the re-threshed processing target in a state of being naturally dropped, for example, a simple configuration such as a cylindrical body And the configuration of the receiving section can be further simplified.
