Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-removing type or general-purpose type combine, and more particularly, to a combine in which a sensor detects the amount of grains bounced by a jumping plate provided at the end of a fried helix.

A combine harvester that cuts and harvests paddy rice, etc. is equipped with a flow sensor that can measure the grain yield as needed for precision agriculture. Then, as this flow rate sensor, for example, a sensor that attaches a detection plate to the load cell and its load point is used, and the harvested grain is made to collide with this detection plate, and the grain value is calculated from the measurement value (weight) obtained from the load cell. The flow rate is estimated (see Patent Document 1). In addition, it has been proved that there is a correlation between the measured value from such a flow rate sensor and the flow rate of the grain although some errors are recognized.

Further, in a combine that measures the flow rate of grains using such a flow rate sensor, the grains that have been shredded and selected in the threshing unit are detected by colliding with the detection plate of the flow rate sensor, so the grains are glen tank. A flow rate sensor is provided near the jumping plate provided at the end of the lifted grain helix that is transported toward, and the amount of the grain is detected by causing the grain that has been bounced by the jumping plate to collide with the detection plate.

More specifically, the jumping plate and the flow rate sensor are housed in a discharge case provided at the upper part of the fried food cylinder, and the discharge case guides the grains bounced by the jumping plate toward the discharge port. Then, the detection plate of the flow rate sensor is provided immediately before the discharge port, whereby the grain guided by the discharge case collides with the detection plate and the amount of the grain is detected, and the grain is guided to the detection plate. It is then discharged into the Glen tank through the discharge port provided in the discharge case, and the grain is collected in the tank.

Also, the grains that collide with the detection plate do not fly well toward the discharge port, and if they fly to the back side of the detection plate on the opposite side, the grains will try to stay on the inside upper surface of the discharge case, which is the back side of the detection plate. .. Therefore, in order to prevent this, the upper surface on the inner side of the discharge case, which is the lower side of the detection plate, is formed as an inclined surface so that the grains that are going to stay along the inclined surface are introduced into the Glen tank from the discharge port. To release.

When the flow rate sensor detects the flow rate of the second product, in order to prevent the second product from staying, a blower is provided on the outer peripheral side of the discharge unit, which is the back side of the detection plate, and a blower is also provided. Guide the wind from the air to the wind guide part and blow away the second object that is trying to stay by this wind.

Japanese Patent No. 4280149

As described above, when the jumping plate and the flow rate sensor are housed in the discharge case provided in the upper part of the frying tube, and the grains bounced by the jumping plate are guided to the discharge case and collide with the detection plate, the grain against the detection plate is detected. The grain collision position is stable, and the grain flow rate can be accurately measured. In addition, the detection plate guides the colliding grains and discharges them from the discharge port of the discharge case in the proper direction in the grain tank, so that the grains can be properly distributed without being unevenly distributed in the grain tank. Can be discharged into the tank.

Moreover, the grains that did not fly well toward the discharge port fall on the inclined surface of the discharge case, which is the lower side of the detection plate, and are discharged into the Glen tank from the discharge port. It is possible to prevent the accuracy of the flow rate measurement from being deteriorated without hindering the operation of.

On the other hand, in order to prevent clogging of each part of the combine, it is recommended to start the harvesting work when the rice leaves that have been wet with night dew or rain have dried. However, if rice that is dry but has fallen overlaid is piled up, it may be difficult to dry, and some rice may be cut off. In addition, in consideration of the work schedule from the next day and so on, there are cases where the work is forcibly carried out even in rainy weather.

When such wet materials are mowed, the grains selected by threshing at the threshing unit, the straw mixed with them, or the dust are also wet, and these are sent to the discharge case provided at the upper part of the fried cylinder. Then, it adheres to the discharge case and accumulates in the case. Moreover, even if these deposits that have been once deposited are dried after that, they rarely peel off spontaneously and continue to be deposited forever.

Therefore, the grains adhering to the inclined surface of the discharge case on the lower side of the detection plate, the straw mixed with it, or dust are not discharged and are accumulated on the spot, and in the worst case, the operation of the detection plate is hindered. The accuracy of flow rate measurement may be reduced. Further, in order to prevent this, even if the blower blows off the deposit, it cannot be easily blown off, and if a strong blower is used, cost increase cannot be avoided.

Then, the flow rate sensor detects the load applied to the load point of the load cell, and in this case, the detected load slightly changes depending on the angle of the grain that collides with the detection plate attached to the load point. Therefore, when the detector plate is worn and replaced due to long-term use, the load cell and the detector plate must be correctly attached to the positions where they were originally attached. Since it is impossible to measure the flow rate and the flow rate may be incorrect, troublesome work such as adjusting the measurement device again occurs.

Therefore, it is desirable to remove and replace only the detection plate attached to the load point while the load cell is attached to the discharge case. However, since the detection plate is provided in the discharge case, it is very difficult to attach and detach only the detection plate.

Therefore, in view of the problems as described above, the present invention stores the pop-out plate and the flow rate sensor in the discharge case, and causes the grain bounced out by the pop-out plate to collide with the detection plate of the flow rate sensor and the amount of the grain. In a combine that detects, even if grains or straws are accumulated in the discharge case, they can be easily removed, and when removing deposits or replacing the detection plate, etc. An object of the present invention is to provide a combine that can easily perform these operations without removing the flow rate sensor.

The present invention, in a first order to solve the above problems, the kernels were selected by shedding in threshing unit, and AgeKoku spiral transferring toward the grain tank, and springing plate provided on the end of AgeKoku helix, detection a plate and a grain quantity flow amount sensor that detect a which Hanedashi by springing plate consists of a load cell, houses a springing plate and the flow sensor, the grain that Hanedashi by springing plate, toward the discharge port In a combine provided with a discharge case that guides with a guide, a base to which a fixed end of a load cell is attached is attached to the outer surface of the discharge case, and the free end of the load cell faces the discharge case, and the load point of the free end is attached. The detection plate attached to the machine collides the grains bounced by the jumping plate, and then discharges them into the Glen tank from the discharge port, while the grains and dust not discharged from the discharge port accumulate. At least the detection plate and the load cell are removed while leaving the detection case and the load cell as they are , and the discharge case is configured so that it can be cleaned.The discharge case is composed of a pop-out portion for housing the pop-out plate and a sensor portion for housing the flow rate sensor. The inside lower surface of the sensor portion that houses the flow rate sensor is formed as a sliding surface of the grain that is inclined downward toward the discharge port, an opening is provided in this sliding surface, and the opening is closed with a removable lid. It is characterized in that the lid, which is a constituent member of the sensor portion on which grain and dust are accumulated, is removed to make it cleanable .

The present invention, in the second, the mounting portion provided on the rear surface side of the detection plate, and forming a mounting regulating surface which brought into contact with the edge of the load cell.

According to the combine of the present invention, the base to which the fixed end of the load cell is attached is attached to the outer surface of the discharge case, and the free end of the load cell is made to face the inside of the discharge case and is attached to the load point of the free end. A discharge case where the grains bounced off by the jumping plate are made to collide with the detection plate and then discharged into the Glen tank from the discharge port, while the grains and dust not discharged from the discharge port are accumulated. At least the detection plate and the load cell are removed and the cleaning is made possible, so that it is possible to remove the components of the discharge case where the grains and dust accumulate and clean them. Measurement accuracy can be maintained.

In addition, the load case is not attached to the constituent members of the discharge case where grains and dust are accumulated, and it is possible to remove and clean only the constituent members of this discharge case while leaving the detection plate and the load cell as they are. , When the detector plate and the load cell are once removed and then reattached, there is no need to make a slight deviation in the attachment position and incorrect flow rate measurement, and it is possible to always properly measure the amount of grain by the flow rate sensor. it can. Moreover, if the constituent members of the discharge case are removed, the detection plate can be easily replaced and the maintainability is improved.

Further, the discharge case is composed of a pop-out portion for housing a pop-out plate and a sensor portion for housing a flow rate sensor. Of these, a constituent member of the sensor portion on which grains and dust are accumulated is removed and can be cleaned. In doing so, the pop-out part that houses the pop-out plate does not deposit the grains and dust that are about to be deposited by the pop-out plate and does not accumulate much, and it interferes with the operation of the detection plate and reduces the accuracy of flow rate measurement. Since there is no risk of causing this, it is possible to remove and clean only the constituent members of the sensor unit on which the grains and dust are deposited, excluding the jumping-out portion that does not need to be removed. The deposit can be removed easily.

In addition, the inner lower surface of the sensor portion that accommodates the flow rate sensor is formed as a grain sliding surface that is inclined downward toward the discharge port, an opening is provided in this sliding surface, and this opening is closed with a removable lid. Then, as in the conventional case, the grains that fly to the back surface side of the detection plate and are about to be deposited can be discharged by sliding down the sliding surface of the sensor portion and the upper surface of the lid. Also, for grain and dust attached to the sliding surface of the sensor part or the upper surface of the lid by cutting wet material, the sliding surface of the sensor part can be cleaned from the opening made by removing the lid, or the lid itself can be cleaned. , Can be easily cleaned.

Then, when the mounting portion provided on the back surface side of the detection plate is provided with a mounting control surface that contacts the edge of the load cell, when the detection plate is replaced, the detection plate is in the original position with respect to the load cell, and It can be mounted at a mounting angle, so that the amount of grain can be measured accurately as before.

Further, when the grain tank 39 is full of grains, the horizontal spiral or the like is driven to discharge the grains from the discharge port 44a provided at the tip of the vertical pipe 44.

Next, the flow rate sensor for detecting the yield of the combine 1 will be described. As shown in FIGS. 4 to 10, the flow rate sensor S is provided in the discharge case 46 of the fried grain cylinder 35. Here, the discharge case 46 is integrally welded to the upper portion of the fried food barrel 35 in which the fried food helix 47 is internally housed, and a pop-out portion for housing a leaching plate 48 provided mainly at the end of the fried food helix 47 and a flow rate sensor. It is composed of a sensor unit that accommodates S.

Among them, the jumping-out portion for housing the jumping-out plate 48 includes a substantially arc-shaped bottom plate 46a having a hole for receiving the lifted-grain spiral 47 and a hole through which the lifted-grain spiral 47 and the jumping-out plate 48 are passed from above. The bearing holder 49 for supporting the shaft upper part of the above is welded to the substantially arc-shaped top plate 46b attached to the periphery of the hole, and the outer peripheral edges of the bottom plate 46a and the top plate 46b so that a space for accommodating the jumping plate 48 is provided therebetween. It is formed from the arc-shaped side plate 46c provided.

On the other hand, the sensor portion that accommodates the flow rate sensor S has a triangular front plate 46d formed by bending the rear side of the bottom plate 46a of the jumping portion downward, and a triangular plate provided rearward of the front plate 46d. It is formed of a rear side plate 46e, rear sides of the front side plate 46d and the rear side plate 46e, and a bottom plate 46f welded to the rear end of the side plate 46c of the protruding portion. In addition, above these, the flow sensor assembly A is attached by a bolt and a nut to the rear end of the top plate 46b of the jumping-out portion and the flanges provided on the upper portions of the rear side plate 46e and the bottom plate 46f to close them.

Then, a discharge plate 46g is welded to the front surface of the discharge case 46 formed of the jumping portion and the sensor portion, which faces the inlet 40a of the Glen tank 39, and the discharge plate 46g is in the front-back direction in which the grain is discharged. A discharge port 46h is provided. Further, the bottom plate 46f of the sensor portion is provided with a rectangular opening 46i having a long side in the vertical direction, and the opening 46i is closed by a lid 46j from the back side.

As shown in FIG. 7A, the flow sensor assembly A described above has a base 50 attached to the upper surface of the sensor portion of the discharge case 46 with bolts and nuts, and an upper peripheral surface of a hole provided in the central portion of the base 50. In addition, a sensor mounting plate 51 which is attached by a long hole or the like so that the angle can be adjusted, and a beam type load cell 53 in which a fixed end portion is mounted on the sensor mounting plate 51 and which is covered with a cover 52 as shown in FIGS. 8 and 9, It is composed of a rectangular resin detection plate 54 which is attached to the load point of the load cell 53 extending downward through a hole provided in the center of the sensor mounting plate 51 with a bolt.

The mounting portion 54b provided on the back surface side of the main body 54a on which the grains of the detection plate 54 collide is attached to the mounting surface 54c mounted at the load point of the load cell 53 and the end edge (end surface) of the load cell 53 on the front end side. When the detection plate 54 is attached to the load point of the load cell 53, the attachment restriction surface 54d of the detection plate 54 can be brought into contact with the edge of the load cell 53 for positioning. The detection plate 54 can always be attached to the load cell 53 at a predetermined position and attachment angle.

Then, in the combine 1 configured as described above, when mowing work is performed in the field, as shown in FIG. 10, the harvested grain (first item) is transferred by the fried grain helix 47 installed in the fried grain cylinder 35. And is discharged into the jumping portion of the discharge case 46 provided on the upper portion of the fried food barrel 35. The grains discharged into the jumping portion are guided by the jumping plate 48 along the inner surface of the side plate 46c, and then collide with the detection plate 54 facing the end of the side plate 46c, and the amount of the grains is measured by the load cell 53. To be measured.

Since the grains that have collided with the detection plate 54 are provided so as to be substantially aligned so that the longitudinal direction of the detection plate 54 is the extension direction of the side plate 46c, the grain may be rapidly changed in direction due to the collision and decelerated. Instead, they are continuously guided and discharged by the detection plate 54. Furthermore, the discharged grains are discharged toward the rear side of the storage section 40 and the gutter section 41 of the Glen tank 39 from the discharge port 46h in the front-back direction of the discharge case 46, and the grains are not unevenly distributed in the Glen tank 39. Grains are sequentially stored in this state.

Further, most of the grains that have collided with the detection plate 54 as described above are guided to the detection plate 54 and discharged as they are, but the amount of the grains discharged to the jumping portion of the discharge case 46 is large, or the detection plate is large. The grain that did not hit 54 well bypasses the detection plate 54 from below the closing plate 46k provided at the upper end of the end of the side plate 46c, turns around to the back surface side thereof, and falls onto the bottom plate 46f and the lid 46j. ..

However, the bottom plate 46f is formed on the sliding surface of the grain that inclines downward toward the discharge port 46h, and the lid 46j that closes the opening 46i of the bottom plate 46f also follows the sliding surface of the grain that inclines downward. As a result, the grains that have fallen on these slide down without being deposited on the spot and are discharged from the discharge port 46h.

Furthermore, when mowing undried grain culms, the grain selected by threshing in the threshing section C, the straw mixed with it, or dust is also wet, and these are placed in the discharge case 46 provided on the upper part of the fried cylinder 35. When sent, it adheres to the inside of the discharge case 46. In this case, the grains and dust that are attached to the jumping-out portion of the discharge case 46 and are about to be deposited are scraped off by the jumping-out plate 48 and blown away, so that they are not deposited much.

However, the grain and dust attached to the sensor portion of the discharge case 46 are gradually deposited in the case because there is no forcible removal means such as the jump plate 48. Moreover, even if these deposits that have been once deposited are dried after that, they rarely peel off spontaneously and continue to be deposited forever. Then, the load cell 53 that detects the amount of grains measures the amount of grains by receiving a load from the detection plate 54 and distorting, and if the load receives the load of the detection plate 54 or the deposit is the load cell 53. If the distortion is prevented, correct measurement results may not be obtained.

Therefore, when grains or dust are accumulated on the sensor portion of the discharge case 46 as described above, it is necessary to quickly remove it. In that case, the lid 46j provided on the bottom plate 46f of the sensor portion is loosened by removing the nut, The deposit attached to this is removed, and the deposit attached to the periphery of the bottom plate 46f is scraped out from the opening 46i. If the cover 46j and the like are covered with a water-repellent coating such as a fluororesin film, the grains and the like will easily slip off, and the frequency of deposit removal work can be reduced.

Since the discharge case 46 is provided above the cylinder cover which is the upper surface of the threshing portion C, an operator can climb on the cylinder cover to attach and detach the lid 46j. Further, when the Glen tank 39 is rotated to the maintenance position, the discharge port 46h of the discharge case 46 is exposed, so the deposit scraped out from the discharge port 46h may be dropped.

On the other hand, the flow rate sensor S composed of the load cell 53 and the detection plate 54 detects the load applied to the load point of the load cell 53, and in this case, the detected load is that of the grains that collide with the detection plate 54 attached to the load point. Subtly changes depending on the angle. Therefore, in the initial setting, the flow rate sensor S is attached to the sensor attachment plate 51, the sensor attachment plate 51 is attached to the base 50 at the set angle, and the flow rate sensor assembly A is attached to the discharge case 46. The amount of grain can be measured accurately.

However, if the detection plate 54 wears due to long-term use of the flow rate sensor S, it needs to be replaced. Then, when replacing the detection plate 54, the lid 46j provided on the bottom plate 46f is removed, and the detection plate 54 attached to the load point of the load cell 53 from the opening 46i of the bottom plate 46f is bolted as in the case of removing the deposit. Remove and replace. Since the attachment restricting surface 54d is provided on the attachment portion 54b of the detection plate 54 as described above, the detection plate 54 can be attached to the load cell 53 at the predetermined position and the attachment angle. ..

It should be noted that, in the case of removing grains and dust accumulated on the sensor portion of the discharge case 46, or when replacing the detection plate 54 of the flow rate sensor S, in the embodiment of the present invention, the lid 46j provided on the bottom plate 46f is removed. Although the work is performed, the front plate 46d, the rear plate 46e, and the bottom plate 46f, which are the constituent members of the sensor unit that houses the flow sensor S, are attached to the discharge case 46 as shown in FIG. The front side plate 46d, the rear side plate 46e, and the bottom plate 46f may be detachably configured by leaving them as they are, or only two of them may be detachably configured. It is not limited.
