  Embodiments of the present invention will be described below with reference to the drawings.

  First, the whole structure of the seed preparation equipment which implements this invention based on FIG.1 and FIG.2 is demonstrated.

  A specific gravity sorting flow adjustment tank 2 is arranged on the lower side of the specific gravity sorting elevator 1, a specific gravity sorting machine 3 is arranged on the lower side of the specific gravity sorting flow adjustment tank 2, and the specific gravity sorting is arranged on the lower side of the specific gravity sorting machine 3. A non-defective elevator 4 is provided. The grain selected by the pre-selection precision sorter (not shown) is sent to the specific gravity selection flow rate adjustment tank 2 via the specific gravity selection elevator 1, and is fed by the feed valve 31 at the bottom of the specific gravity selection flow rate adjustment tank 2. It is fed out and sent to a specific gravity sorter 3 for specific gravity sorting.

  The specific gravity-selected non-defective product that has been subjected to specific gravity selection by the specific gravity sorter 3 is sent to the specific gravity-selective non-defective elevator 4 through the feed flow path 3a, and the grain that has been lifted by the specific gravity-selective non-defective product elevator 4 is the lower switching means 5, feed flow Via the path 4a, it is sent to the refiner 6 on the lower side, or is returned to the specific gravity sorting flow rate adjusting tank 2 via the switching means 5 and the return flow path 4b.

  Further, the specific gravity sorting waste particles sorted by the specific gravity sorter 3 are sent to the waste grain tank 10 via the waste grain flow path 8 and the waste grain elevator 9. Further, the specific gravity-sorted intermediate particles selected by the specific gravity sorter 3 are returned to the specific gravity-sorting elevator 1 via the intermediate-grain return channel 11 and again subjected to specific gravity selection.

  In addition, on the lower side of the selection machine 6, a color selection elevator 12, a color selection flow adjustment tank 13a, a color selection machine 13, a color selection good elevator 14, a seed disinfection elevator 15, a switching means 15a, a disinfection flow adjustment tank. 16, seed disinfector 17, seed dryer 18, weighing elevator 19, weighing tanks 20 and 20 are arranged.

  A feed valve 31 is provided at the bottom of the specific gravity sorting flow rate adjustment tank 2, and a plurality of set amount detection sensors SE1,... Is provided with a grain weight loss detection sensor SE3. The operation panel (not shown) is provided with an operation start switch SW1, an operation stop switch SW2, a grain type property selection switch SW3,.

  Switches and sensors are connected to the input side of the controller 33 for control, and a work machine, elevator, and switching means are connected to the output side via a motor for driving the sorter, a motor for driving the elevator, and switching drive means. Connected.

  Further, the controller 33 is provided with detection sensor selection means, and when a grain with a steep repose angle is selected by an operator's selection operation from among the grain variety property selection switches SW3,..., A plurality of set amount detection sensors SE1,. If the lower sensor is selected as a sensor for detection and a grain having a moderate angle of repose is selected, the upper sensor among the plurality of set amount detection sensors SE1,. Selected.

  When the set amount detection sensor SE1 selected and determined detects the presence of grain, the specific gravity sorting elevator 1 is stopped based on the elevator clogging prevention means of the controller 33, and the set amount detection sensor SE1 does not have grain. Is detected, clogging prevention control is executed in which the driving of the specific gravity sorting elevator 1 is resumed.

  According to the above configuration, when preparing a plurality of grain varieties with different conveyance efficiency and angle of repose or the same grain with different properties, the specific gravity sorting flow control tank 2 fills the grain up to the top while increasing the efficiency of grain preparation work. The clogging of the flow rate adjusting tank 2 can be prevented.

  Further, the set amount detection sensor SE1 may be constituted by a non-contact type. As shown in FIG. 3, when grain flows down from the specific gravity sorting elevator 1 to the upper center of the specific gravity sorting flow adjustment tank 2 through the flow down cylinder 36, the grain is in accordance with the angle of repose where the upper central portion is high and the peripheral portion is low. Be contained. The set amount detection sensor SE1 is a single non-contact sensor, and the upper surface of the stored grain is detected by irradiating the grain repose angle with detection light. A non-contact type set amount detection sensor SE1 is arranged around the ceiling of the flow rate adjusting tank 2 for selecting the specific gravity, and the detection light is irradiated downward to receive the reflected light from the lower side of the upper side of the angle of repose of the grain. The state is detected.

  When a grain with a steep repose angle is selected from the grain type property selection switches SW3,..., The detection sensitivity of the set amount detection sensor SE1 is increased based on the detection sensor sensitivity adjustment means of the controller 33. When a grain having a low angle of repose is selected, the detection sensitivity is adjusted to the decreasing side and the sensitivity adjustment setting is made.

  Next, the detection contents of the disinfection set amount detection sensors SE1,... Of the disinfection flow rate adjustment tank 16 will be described with reference to FIGS.

  In the seed preparation facility, different types of high moisture grains and low moisture grains of the same varieties may be stored in the same disinfecting flow control tank 16, and this embodiment corresponds to such a case. The detection amount of the set amount detection sensors SE1,... For disinfection is optimized to prevent clogging of the tank.

  The prepared low moisture grains are supplied from the seed disinfection elevator 15 to the measuring tank 20 via the switching means 15a and the feed flow path 15b, or from the seed disinfection elevator 15 via the switching means 15a and the feed flow path 15c. The cereal is sent to the disinfection flow rate adjustment tank 16, and the cereal is fed by the feed valve 16 a of the sterilization flow rate adjustment tank 16, and weighed via the lower seed disinfector 17, seed dryer 18, and the weighing tank elevator 19. The tank 20 is configured to send disinfected and dried high moisture grains.

  A plurality of upper and lower set amount detection sensors SE1,... Are arranged on the side wall of the measuring tank 20, and a plurality of grain variety property selection switches SW3,. ... Is selected based on the set amount detection sensor selection means of the controller 33, so that either the upper or lower set amount detection sensor SE1 for disinfection is selected.

  When, for example, a steeply inclined grain having a repose angle is selected from among the grain type property selection switches SW3,..., A lower sensor is detected from a plurality of upper and lower set amount detection sensors SE1,. If a grain with a gentle angle of repose is selected, the upper sensor is selected and determined from among the upper and lower set amount detection sensors SE1,.

  When the set amount detection sensor SE1 in charge of detection detects the presence of grain during the preparation work, the driving of either the seed disinfection elevator 15 or the weighing tank elevator 19 is stopped based on the clogging prevention control means of the controller 33, and When the set amount detection sensor SE1 detects the absence of grain, an interlock control is executed in which the driving of either the seed disinfection elevator 15 or the metering tank elevator 19 is resumed.

  According to the above configuration, even when low moisture grains or high moisture grains having different angles of repose are stored in the measuring tank 20, the measuring tank 20 is filled with the grains up to the upper part of the measuring tank 20 while effectively using the tank to improve the weighing work efficiency. It is possible to prevent clogging.

  When a single grain full sensor is installed in the flow rate adjustment tank, the setting position is determined in accordance with the grain having a steep angle of repose. When the sensor is arranged in this way, if a grain having a gentle angle of repose is accommodated, a sufficient accumulation layer is not formed on the upper part of the tank, and the grain capacity is reduced, so that a large tank is provided to ensure a predetermined work efficiency. It must be installed, which also increases costs.

  However, according to the above-described configuration, the plurality of set amount detection sensors SE1,... Can be used properly according to the varieties and properties of cereals, and tank clogging prevention control can be performed while accommodating cereals up to the upper part of the tank.

  Further, in the initial stage of work over a predetermined time from the start of operation, sorting by the specific gravity sorter 3 is not stable, resulting in sorting failure. Therefore, when the grain return control is performed in which the specific gravity sorting defective grain of the specific gravity sorter 3 is returned to the specific gravity sorting flow rate adjustment tank 2 via the return flow path 4b based on the work initial grain return control means of the controller 33, the flow rate adjustment tank. 2, the amount of return of the grain increases, and the grain fullness is likely to be reached.

  During the grain return control, the specific gravity sorting elevator 1 is stopped by detecting the set quantity of the set quantity detection sensor SE1 and the grain supply from the previous process is stopped. However, the return stop of the return grain from the return flow path 4b is restricted. Therefore, there is a problem that the flow rate adjusting tank 2 is easily clogged. Also, during normal work after a predetermined time at the beginning of the work, if the sorting state of the specific gravity sorter 3 is stable and the return control of the grains with poor specific gravity sorting is stopped, there is a margin for detection of the set amount, and the grain is placed in the upper part of the tank. It becomes easy to create a blank part.

  Therefore, when detecting the set amount with the plurality of set amount detection sensors SE1,..., The set amount is detected by the lower set amount detection sensor SE1 at the initial stage of operation, and the storage space for the return grain amount is secured to clog the tank. Can be prevented. In the normal working state, the set amount detection sensor SE1 on the upper side detects the set amount, so that the grain can be secured up to the upper part of the tank and the preparation work can be efficiently performed while preventing the tank from clogging.

  Further, based on the sensor selection means of the controller 33, it is determined whether the switching means 5 on the lower side of the specific gravity selecting good elevator 4 is in the return state or the next process feed state, and whether it is the initial work or the normal work, and the set amount detection similar to the above is detected. The selection of the sensor SE1 may be determined.

  In addition, a return grain detection sensor SE2 is disposed in the return flow path 4b connected from the specific gravity sorting non-defective elevator 4 to the specific gravity sorting flow rate adjusting tank 2, and the return grain detection sensor SE2 detects the presence or absence of the return grain. Alternatively, the set amount detection sensors SE1,... May be selected, and the selection of the set amount detection sensor SE1 may be determined in the same manner as described above.

  Further, the detection sensitivity of the detection light of the non-contact type set amount detection sensor SE1 is adjusted to be high or low depending on whether the switching means 5 on the lower side of the specific gravity sorting non-defective elevator 4 is in the return switching state or the next process feeding state. You may make it respond | correspond to the state which is easy to collect or the state which does not collect easily.
