Guide bar for exposing the separator plate and combine with the same {Guide bar for exposing the separator plate and Combine with the same}

The present invention relates to a combine, and more particularly, by raising the crops covered in advance of the weeding board so that the weeding board hidden by the crops is exposed to the outside, the driver driving the combine can accurately locate the standard weeding board with the naked eye. It relates to a guide bar for exposing a dividing board and a combine having the same.

In general, a combine is a machine that harvests grains such as rice, barley, and beans at farmhouses. It is a harvesting machine that automatically reaps and threshes crops, and at the same time puts a certain amount into a bag and packs it. It is one of the agricultural machines that perform the most complex role.

These combines are largely divided into self-removal type and normal type, and self-removal type combines are derived from automatic threshing machines and have a traveling device, reaping unit, and conveying device added to the automatic threshing machine, and only the ears of the threshed crop are put in the threshing unit and threshed It is a repair supply type combine that does.

The normal combine was developed for the purpose of harvesting barley in the West, and threshing by simultaneously passing the harvested stems and ears through the threshing machine can be largely distinguished from the cutting type.

The combine 100 used for harvesting crops such as rice in the autumn harvest season has a main body 10 having a driver's seat 15 in which a driver sits with a plurality of operating handles, as shown in FIGS. 1A and 1B And, the running part 20 provided in the lower part of the main body and driven by the engine driving, and the lower part of the main body is provided in front of the main body to raise the crops, such as grains such as rice, and the upper and lower cutting blades A harvesting unit 30 for cutting, a conveying unit for transferring the harvested crops to the threshing unit, a threshing sorting unit 40 for threshing, sorting, and sorting the crops conveyed by the conveying unit, and threshing the crops in a tank or bag It may include a grain processing unit 50 for transporting and a rice straw processing unit for processing the rest of the grains threshed.

In the combine 100 having such a configuration, a plurality of weeding plates 31 provided at regular intervals in the width direction at the front end of the reaping frame 35 of the reaping unit 30, the mowing width range of the crop to be harvested While limiting, the crops tilted on the floor are raised up and then the erected crops are guided to the upper and lower cutting blades provided at the lower part of the harvesting unit.

The reaping frame 35 is provided with a plurality of lifting lugs 33 provided in a chain that is unidirectionally circulated by a driving source so as to pull the stems of the crops up in a reaping posture suitable for cutting the stems before harvesting by cutting the stems of the crops and circulating. The crops raised and harvested by the lifting lug are transported to the conveying unit to be processed by the threshing sorting unit 40 for threshing sorting.

However, the seating position of the driver seated in the driver's seat of the main body is the installation position of the weeding board 31 provided below the harvesting unit 30 and the auxiliary weeding board 32 provided between the grassing boards 32 adjacent to each other. It is relatively very high, and since crops such as rice at harvest time are tilted to one side by the weight of the ears, the driver determines the position of the weeding plate 31 that splits the rows of crops to be harvested in advance from the front of the combine. It was difficult to confirm accurately with the naked eye.

In particular, during the initial work of harvesting crops using the combine, in the process of driving along the dike higher than the floor, it is provided in front of the reaping unit by the ear leaned toward the dike and is located on the rightmost side of the weeding board close to the floor Since the weeding board for setting the reference position is covered, it is difficult for the operator driving the combine to secure a field of view to visually check the position of the rightmost weeding board, which becomes the reference position during operation, so that the rightmost weeding board is It was difficult to make emergency braking so as not to collide with obstacles such as rocks or protrusions scattered in the rice paddies.

As a result, collision accidents in which the dividing board is damaged or damaged due to direct collision between the obstacle and the dividing board frequently occurred.

In addition, the cost of repairing the weeding board or replacing it with a new one increases due to damage and damage to the weeding board, and the time to harvest crops in the harvest season is delayed due to the repair and replacement work time of the weeding board. On the other hand, In order to prevent breakage and damage to the weeding board due to collision with obstacles at the beginning of crop harvesting along the rice paddy dike, it acted as a major cause of increasing the workload of the operator driving the combine.
