Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a combine provided with a tank for storing grains supplied from a threshing apparatus.

[0002]

2. Description of the Related Art Conventionally, in such a combine, there has been provided an alarm means for alarming when the amount of grains in a tank is full.

[0003]

By the way, the harvested grains need to be dried as quickly as possible in order to prevent the quality deterioration, to a moisture content which can prevent the quality deterioration. It is necessary to put the grains into a dryer during the same day. On the other hand, when drying kernels, the amount of dry processing that can be performed at one time is limited. For example, when a producer owns a dryer, the drying capacity of the dryer is limited. In addition, even when the harvested grains are brought into a rice center or the like where the grains supplied from a plurality of producers are aggregated and dried, the amount of grains that can be brought into the rice center at one time is limited. There are cases. Therefore, it is more preferable for the producer to adjust the harvest amount of the grain to match the amount that can be dried at one time, from the viewpoint of work efficiency and management of the grain. In this case, when harvesting the grains in the combine, it is necessary to stop the harvesting when the amount of the grains stored in the tank reaches a desired amount until it is full.

[0004] Further, the softer the ground on the field where the combine travels, the easier it is for the ground contacting portion of the traveling device of the combine to sink into the ground, so that the steering performance of the combine decreases. Therefore, when traveling in a soft field, the larger the amount of grains stored in the tank, the heavier the combine, and the easier it is for the ground contact portion of the traveling device to sink into the ground. It may be better to stop harvesting when the amount of grain reaches a predetermined amount.

However, in the conventional combine, a warning is issued only when the amount of grains in the tank is full, so that the harvest amount of the grains is adjusted to, for example, the amount that can be dried and the like. There is a disadvantage that it cannot be easily performed, and improvement has been desired.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily manage the yield of grain.

[0007]

According to the first aspect of the present invention, if the set amount for alarm is arbitrarily changed and adjusted, when the amount of grains in the tank reaches the set amount for alarm, The alarm means operates an alarm. Therefore, it is possible to easily determine whether or not the amount of grain in the tank has reached an arbitrary amount, based on the alarm operation of the alarm means, so that it is easy to manage the yield of grain. Is now available.

By the way, the amount of grain when the tank is full is known in advance. Therefore, if it becomes possible to easily determine that the amount of grains in the tank has reached an arbitrary amount, the storage allowance indicates how much grain can be stored in the tank in the future. It is convenient because the amount can be easily known.

According to the second aspect of the present invention, if the alarm set amount is arbitrarily set by the alarm set amount setting unit, the detected kernel amount of the kernel amount detection unit can be set to the alarm amount. When the alarm amount is equal to or greater than the alarm set amount set by the set amount setting means, the alarm means is activated.

[0010] Incidentally, as a configuration for changing and adjusting the set amount for alarm, for example, when the storage height of the grains in the tank reaches within the detection range, an alarm command signal for alarming the alarm means is issued. It is conceivable to provide a grain detection sensor configured to transmit a signal so that the height with respect to the tank can be changed and adjusted.In this case, in order to adjust and change the alarm set amount, the grain detection sensor needs to be adjusted. Since the height must be adjusted, there is a disadvantage that the operation is complicated. On the other hand, by arbitrarily setting the alarm set amount by the alarm set amount setting means, it is possible to easily change and adjust the alarm set amount, thereby improving operability.

According to the third aspect of the present invention, the amount of grain in the tank can be detected steplessly by the ultrasonic sensor. Incidentally, as a specific configuration of the grain amount detection means, for example, a plurality of grain detection sensors configured to send a detection signal when the storage height of the grains in the tank reaches within the detection range, the tank, Move the grain detection sensor, which is configured to be spaced apart from each other in the height direction, or is configured to transmit a detection signal when a grain is present in the detection range, in the tank in the height direction A configuration is conceivable in which the configuration is freely provided and the amount of grain is detected based on the amount of movement of the grain detection sensor. However, in such a case, there is a disadvantage that the configuration becomes complicated.

On the other hand, when the grain amount detecting means is constituted by an ultrasonic sensor, the structure is simplified as compared with the above-mentioned structure, so that the implementation cost of the present invention can be reduced. it can. Moreover, since the amount of grain can be detected in a stepless manner, the set amount for alarm for operating the alarm can be set to an arbitrary value, which makes it easy to manage the yield of grain. .
