JP 2003-289712 A

  In the above prior art, even if the grain amount in the Glen tank is displayed stepwise by a plurality of culm sensors, it is determined whether or not the remaining one-step harvesting operation is possible in the recent large-division field harvesting operation. Because it is difficult, the grain in the grain tank may become a predetermined amount (full) at the harvest point away from the grain discharge position of the grain tank. In that case, it is separated from the harvest point without performing the harvesting work. There is a problem that it is necessary to move to a new grain discharge position. In addition, the amount of grain in the Glen tank that can be transported from the field is different due to the difference in capacity of the transportation means such as the truck bed or container or Glenback, and the grains discharged from the Glen tank to the transportation means are excessive and insufficient. There is a problem that it is necessary to start the harvesting operation in the next process while leaving the grain in the Glen tank.

  An object of the present invention is to provide a combine that can efficiently collect an appropriate amount of grain in a Glen tank, can reduce a loss of harvesting work time, and can improve a harvesting work efficiency.

  In order to achieve the object, the combine of the invention according to claim 1 includes a reaping device, a threshing device, and a glen tank, and is configured to detect the grains collected in the glen tank with a koji sensor. In the combine, the grain until the grain collection amount in the grain tank reaches the capacity of the transport means based on the output of the dredging sensor that detects the grain collection in the grain tank at the beginning or middle of the harvesting operation The grain collection time is calculated, and the remaining time during which the grain can be harvested can be notified to the operator.

  The invention described in claim 2 is the combine according to claim 1, further comprising a transport capacity setting device for initially setting the capacity of the transport means necessary for calculating the remaining time during which the grain can be harvested. is there.

  According to a third aspect of the present invention, in the combine according to the first aspect, the grain yield in the grain tank and the remaining time during which the grain can be harvested are displayed over time on the display. It is configured.

  According to a fourth aspect of the present invention, in the combine according to the first aspect of the present invention, the full tank position selection paddle sensor capable of adjusting a position in a direction in which the grain in the grain tank increases or decreases is provided in the grain tank. .

  A fifth aspect of the present invention is the combine according to the first aspect, comprising a grain discharge conveyor for discharging the grain in the grain tank, wherein the operation of the grain discharge conveyor is detected. In addition, the total discharge amount of the grain in the Glen tank and the remaining discharge amount of the grain in the Glen tank are calculated, and the total discharge amount or the remaining discharge amount can be recorded.

  According to the first aspect of the present invention, a harvesting operation is started in a combine that includes a reaping device, a threshing device, and a Glen tank, and that is configured to detect the grains collected in the Glen tank by a straw sensor. Based on the output of the cocoon sensor that detects the collected grain in the Glen tank in the initial or middle period, the grain collection time until the grain collection amount in the Glen tank reaches the capacity of the transportation means is calculated. Since the remaining time in which the grain can be harvested can be notified to the operator, it is difficult to determine whether or not the remaining one-step harvesting is possible. However, the grain in the grain tank does not become a predetermined amount (full) at the harvest point away from the grain discharge position of the grain tank. That is, it is not necessary to move to a grain discharge position away from the harvesting point without performing a harvesting operation. The grain in the grain tank can be made a predetermined amount (full) at a harvest point near the grain discharge position. An appropriate amount of grain can be efficiently collected in the grain tank, loss of harvesting work time can be reduced, and harvesting work efficiency can be improved.

  Moreover, it is possible to prevent the amount of kernel discharged from the grain tank to the transporting means from being excessive or insufficient while the amount of the kernel can be easily detected stepwise by the plurality of low-cost cocoon sensors. For example, an expensive camera or other kernel sensor is not required, kernel mass detection is unnecessary, and the moisture content of the harvested kernel is hardly affected. The harvesting operation in the process can be resumed, and the distance to move to the grain discharging position in a state where the grain tank is full can be shortened. The grain can be filled into a small-capacity grain back (transport means) or the like without worrying about the discharge clogging, and the transportability of the collected grain can be improved.

  According to the invention described in claim 2, since the transportation capacity setting device that initially sets the capacity of the transportation means necessary for calculating the remaining time during which the grain can be harvested is provided, The container desired by the operator, the grain back, or the truck bed can be easily used. The distance from the harvest point to the grain discharge position can be shortened. The workability of transporting collected grains can be improved.

  According to the third aspect of the present invention, the grain yield in the Glen tank and the remaining time during which the grain can be harvested are displayed over time on the display. The volume change of the harvested grain in the Glen tank can be notified to the operator in real time. Based on the volume of the grain corresponding to the capacity of the transport means, the operator can easily predict the grain discharge time in the Glen tank. For example, by forming the indicator with a large number of LEDs, it is possible to easily display the grain yield in the grain tank and the grain discharge timing in the grain tank in a form that is easy for an operator to confirm.

  According to the fourth aspect of the present invention, since the full tank position selection rod sensor capable of adjusting the position in the direction in which the grain in the grain tank increases or decreases is provided in the grain tank, the operator can The grain full quantity can be selected and the grain in the Glen tank can be discharged. Special transport means are available. In a wet field or the like, overloading can be prevented and the inclination or settlement of the aircraft can be reduced.

  According to invention of Claim 5, it is the structure provided with the grain discharge conveyor which discharges the grain in the said Glen tank, Comprising: The operation | movement of the said grain discharge conveyor is detected, Since the total amount of grain discharged and the amount of remaining grain discharged in the Glen tank are calculated and the total amount discharged or the amount remaining discharged can be recorded, it is discharged from the Glen tank to the transportation means. Even when the grain is left and the grain is left in the grain tank and the harvesting operation of the next step is started, the grain in the grain tank is taken into consideration in consideration of the residual amount of grain in the grain tank. The grain collection time until the grain collection amount reaches the capacity of the transportation means can be calculated. At the harvesting point close to the grain discharge position, the grain in the Glen tank can be made a predetermined amount (full). An appropriate amount of grain can be efficiently collected in the Glen tank, and the harvesting work efficiency can be improved. The workability of transporting collected grains can be improved.

As shown in FIGS. 4 and 5, a grain collection controller 100 such as a microcomputer having a ROM storing a control program and a RAM storing various data is provided. On the input side of the grain collection controller 100, a work clutch sensor 101 that detects the operation (harvesting work) of the reaping device 3 and the threshing device, a vehicle speed sensor 102 that detects the rotational speed of the traveling crawler 2, and the reaping device 3 Among the grain feeders 224, the grain sensor 103 for detecting the presence or absence of the harvested grain straw transported by the grain hammering mechanism 237, the waste sensor 104 for detecting the presence or absence of the waste carried by the waste chain 234, A transport capacity setting unit 105 for initially setting the transport capacity of a transport means such as a truck bed or a container or a grain back is connected.

  Further, on the input side of the grain collection controller 100, a limit switch type lower hail sensor 106 disposed in the vicinity of the bottom of the Glen tank 7 and a limit switch type middle hull located in the upper and lower middle part of the Glen tank 7. A sensor 107, a limit switch type upper soot sensor 108 disposed near the upper part in the Glen tank 7, and a full position selection soot sensor provided so that the position of the grain in the Glen tank 7 can be adjusted (vertical direction). 109 and a koji discharge sensor 110 that detects the grain discharge operation of the grain discharge conveyor 8 are connected. A full position selection rod sensor 109 is attached to the Glen tank 7 by the position adjusting operation tool 111 (see FIG. 3).

  Further, as shown in FIGS. 3 and 4, on the output side of the grain collection controller 100, a yield indicator formed by a plurality of light emitting diode type indicators for displaying the grain amount in the grain tank 7 in a stepless manner. 112, a harvestable time indicator 113 that displays the remaining time that can be harvested until the grain in the Glen tank 7 reaches a predetermined amount (full), and a predetermined amount of grain is filled in the Glen tank 7 A full alarm device 114 such as a buzzer for alarming the operator is connected. The harvestable time display 113 is formed by a plurality of light emitting diode type indicators that display the remaining time that can be harvested steplessly and a seven segment type liquid crystal display panel.

  For example, the grain amount in the Glen tank 7 is displayed on the indicator of the yield indicator 112 in real time. Further, the remaining time during which the harvesting work can be performed and the time elapsed since the start of the harvesting work are displayed in real time on the indicator of the harvestable time display 113. The remaining time that can be harvested such as the remaining 15 minutes and the time that has elapsed since the beginning of the harvesting operation such as the lapse of 5 minutes are displayed on the liquid crystal display panel of the harvestable time display 113. On the other hand, when the grain tank 7 is filled with a predetermined amount of grain, or when the harvest time when the grain tank 7 is filled with a predetermined amount of grain has elapsed, the buzzer of the full alarm device 114 sounds. Alarm the operator.

  Next, the grain collection control mode will be described with reference to the flowchart of FIG. As shown in FIG. 5, when the harvesting operation is started, the cereal sensor presence / absence detection value of the culm sensor 107, the rejection sensor 106 presence / absence detection value, and the threshing drive stop detection of the work clutch sensor 103 are detected. A value is read (S1). And when there is a harvested cereal cocoon or a culling (S2; yes), the carrying capacity setter 105 value, the lower heel sensor 106 value, the middle heel sensor 107 value, the full position selection heel sensor 109 value, and the previous time Is read (S3), and the remaining time that can be harvested until the grain in the grain tank 7 reaches a predetermined amount (full) is calculated (S4).

  That is, based on the time from the start of the harvesting operation until the detection of the grain by the lower basket sensor 106, the time from the detection of the grain by the lower basket sensor 106 to the amount of the grain in the Glen tank 7 reaches the predetermined amount This is calculated as the remaining time during which harvesting work is possible until the grain in the tank 7 reaches a predetermined amount (full). When the remaining time during which the harvesting operation is possible is not zero (S5; no), the grain amount in the Glen tank 7 is displayed in real time on the indicator of the yield indicator 112 (S6). The buzzer of the full alarm device 114 sounds by an operation different from the full alert for the grain detection of the lower heel sensor 106 and the grain detection of the middle heel sensor 107 (S6).

  Further, the remaining time during which the harvesting operation until the grain in the Glen tank 7 reaches a predetermined amount (full) and the time elapsed since the start of the harvesting operation are displayed in real time on the indicator of the harvestable time display 113. (S7) On the other hand, the remaining number of hours that can be harvested, such as the remaining 15 minutes, and the number of hours that have elapsed since the beginning of the harvesting operation, such as 5 minutes, are displayed numerically on the liquid crystal display panel of the harvestable time display 113 (S7). The operator of the harvestable time display 113 confirms the display of the remaining number of hours, and the grain in the Glen tank 7 becomes a predetermined amount (full) at a place away from the position where the grain in the Glen tank 7 is discharged. Avoiding this, you can start harvesting work in the next process.

  When the remaining time that can be harvested until the grain in the Glen tank 7 reaches a predetermined amount (full) becomes zero (S5; yes), the buzzer of the full alarm 114 sounds and the Glen tank The operator is warned that the amount of grains in 7 has reached a predetermined amount (full) (S8). In conjunction with the buzzer sounding of the full alarm device 114, deceleration control of the output rotational speed transmitted from the engine 70 to the traveling crawler 2 is executed. As a result, the traveling driving force transmitted from the engine 70 to the traveling crawler 2 is decelerated when the grain in the Glen tank 7 reaches a predetermined amount (full). That is, when the traveling speed (vehicle speed) of the traveling machine body 1 is switched to the low speed side, the amount of grains carried into the Glen tank 7 can be reduced, and extra grains are collected in the Glen tank 7. Can be prevented.

  Further, even when the engine 70 is operating, when there is no harvested culm or waste (S2; no), that is, when the harvesting or threshing operation is interrupted and the grain is not collected, The traveling machine body 1 is moved to the grain discharge position at the edge of the field near the carrier of the truck parked on the side farm road, the container mounted on the truck, or the transportation means such as the grain bag mounted on the truck, and the grain The grain discharge conveyor 8 (transverse feed auger 51, vertical feed auger 52, discharge auger 54) is operated (S10; yes), and the grain discharge conveyor 8 discharges the grains in the grain tank 7 to the inside of the conveying means. In the case of making it, the amount of remaining grain in the glen tank 7 is calculated based on the time for entering the straw discharge clutch detected by the straw discharge sensor 110 (operation time of the grain discharge conveyor 8) (S11), The discharge remaining grain amount controller 100, and stores the discharged remaining paddy weight values step 3 (S12).

  In step 4, the grain collection time from the start of the harvesting operation until the lower dredge sensor 106 detects the grain is calculated except for the previous discharged remaining grain amount in step 11. The remaining time that can be harvested until the grain reaches a predetermined amount (full) is accurately calculated in accordance with the actual harvesting operation. The remaining time that can be harvested until the grain in the grain tank 7 reaches a predetermined amount (full) is accurately notified to the operator by the display of the harvestable time display 113.

  As shown in FIGS. 4 and 5, the reaping device 3, the threshing device 5, and the grain tank 7 are provided, and the grains collected in the grain tank 7 are detected by the straw sensors 106, 107, 108, and 109. In the configured combine, the amount of grains collected in the grain tank 7 is determined by the transport means based on the output of the dredging sensors 106, 107, 108, 109 that detect the collected grains in the grain tank 7 at the beginning or middle of the harvesting operation. The grain collection time until reaching the capacity is calculated, and the remaining time during which the grain can be harvested can be notified to the operator.

  Therefore, even in a recent large-division field harvesting operation in which it is difficult to determine whether or not the remaining one-step harvesting is possible, the grain tank 7 has a harvest point far from the grain discharge position. The grain does not become a predetermined amount (full). That is, it is not necessary to move to a grain discharge position away from the harvesting point without performing a harvesting operation. The grain in the Glen tank 7 can be made a predetermined amount (full) at the harvest point near the grain discharge position. An appropriate amount of grains can be efficiently collected in the Glen tank 7, a loss in harvesting work time can be reduced, and the harvesting work efficiency can be improved.

  Moreover, the amount of grain discharged from the glen tank 7 to the transportation means is excessive or insufficient while the amount of grain can be easily detected step by step by the low cost plurality of straw sensors 106, 107, 108, 109. Can be prevented. For example, a grain quantity sensor such as an expensive camera is unnecessary, and mass detection of the grain is unnecessary, and it is hardly affected by moisture change of the harvested grain. The harvesting operation in the process can be resumed, and the distance to move to the grain discharge position can be shortened in a state where the grain is full in the Glen tank 7. Grains can be easily filled into a small-capacity grain bag (transportation means) or the like without worrying about discharge clogging, and the transportability of collected grains can be improved.

  As shown in FIGS. 4 and 5, a transport capacity setting unit 105 for initially setting the capacity of the transport means necessary for calculating the remaining time during which the grain can be harvested is provided. Therefore, a container, a grain back, a truck bed, etc. which an operator desires can be easily used as a transportation means. The distance from the harvest point to the grain discharge position can be shortened. The workability of transporting collected grains can be improved.

  As shown in FIGS. 4 and 5, the grain yield in the grain tank 7 and the remaining time during which the grain can be harvested are displayed on the harvestable time display 113 over time. . Therefore, the volume change of the harvested grain in the Glen tank 7 can be notified to the operator in real time. Based on the volume of the grain corresponding to the capacity of the transportation means, the operator can easily predict the grain discharge time in the Glen tank 7. For example, by forming the harvestable time indicator 113 with a large number of LEDs, it is possible to easily display the grain yield in the grain tank 7 and the grain discharge timing in the grain tank 7 in a form that can be easily confirmed by the operator. .

  As shown in FIGS. 4 and 5, the Glen tank 7 is provided with a full position selection rod sensor 109 that can be adjusted in the direction in which the grains in the Glen tank 7 increase or decrease. The grain full quantity can be selected, and the grain in the Glen tank 7 can be discharged. Special transport means are available. In a wet field or the like, overloading can be prevented to reduce the inclination or settlement of the aircraft.

  As shown in FIGS. 4 and 5, the structure is provided with a grain discharge conveyor 8 that discharges the grain in the grain tank 7, and detects the operation of the grain discharge conveyor 8, and the grain in the grain tank 7. The total discharge amount of grain and the remaining discharge amount of grain in the grain tank 7 are calculated, and the total discharge amount or the remaining discharge amount can be recorded. Therefore, even if the grain discharged from the grain tank 7 to the transportation means is left and the grain is left in the grain tank 7, even if the harvesting operation in the next step is started, the grain remaining in the grain tank 7 is left. Considering the quantity, the grain collection time until the grain collection amount in the Glen tank 7 reaches the capacity of the transportation means can be calculated. The grain in the Glen tank 7 can be made a predetermined amount (full) at the harvest point near the grain discharge position. An appropriate amount of grain can be efficiently collected in the Glen tank 7 and the harvesting work efficiency can be improved. The workability of transporting collected grains can be improved.
