{ATTACHING AND DEATTACHING STRUCTURE FOR COMBINE GRAIN SIEVE}

The present invention relates to a structure for attaching and detaching a grain sieve of a combine. More specifically, the grain sieve provided in the sorting device of the combine is slidably coupled to the lower frame, so that grain can be separated from the side of the lower frame without separating the sorting device from the lower frame. This relates to a structure for attaching and detaching the grain sieve of a combine that allows the sieve to be replaced so that the grain sieve corresponding to the type of grain being harvested can be selected and used.

A combine is an agricultural machine that threshes the grain harvested from farmland and then pours it into sacks or barrels. It performs the tasks of cutting and threshing the grain at the same time. Therefore, it is also called a double harvester, combined harvester, and comprehensive harvester.

Combines are divided into a normal type (Western type) combine, which is mainly used for rice, and a self-contained type combine developed in Japan to suit the characteristics of rice. The self-cutting type combine uses a method of cutting the moisture-filled rice with a cutter knife in the harvesting section and then pulling it into the vehicle body and pouring it into a sack. The normal type combine uses a dedicated cutter with horizontally elongated blades connected to a reel and a cutting-edge system inside the vehicle body to pull the rice. I am using the raising method.

As shown in Figure 1, a normal combine includes a reaping unit (1) that guides the stalks and is equipped with a ring-shaped dedicated cover (2), a transfer unit (3) that guides the cut grain stalks to the threshing unit, and a grain It is equipped with a threshing unit that shakes out the grains, and consists of a main body (5) connected to the reaping unit (1) at the front, a running unit (4) connected to the main body (5) at the top, and a discharge unit (6) that discharges the threshed grain. there is. And at the lower part of the threshing part of the main body (5), a sorting part (A) is provided to separate foreign substances and grains.

As shown in FIG. 2, the sorting unit is composed of a lower frame assembly 200 provided at the lower part of the threshing unit and a sorting device 100 that is slidably coupled to the lower frame assembly 200 to separate foreign substances and grains.

The sorting device 100 has a grain plate 110 installed on the upper side of the entrance side of the sorting device frame 150 to separate grains from foreign substances such as gums using density differences, and to sort out grains remaining in a large amount of gums. A chafing sieve 140 installed at an angle at the rear of the sorting device frame 150, a plurality of sorting pins 120 installed at the rear of the grain plate 110 to discharge the initially selected grains to the lower part, It is fastened to the lower part of the sorting device frame 150 with a fixing bolt 135 and includes a grain sieve 130 that selects and discharges the grains that have fallen to the bottom of the sorting pin 110.

And the lower frame assembly 200 includes a pair of lower frames 250 with a guide rail 255 installed on the upper inner side for guiding the sorting device 100, and a lower frame 250 located on the lower side of the grain sieve 130. ) and a screw-type first conveyor 210 that is rotatably installed in the grain sieve 130 and transports the grains selected by the grain sieve 130 to the grain tank, outside the grain sieve 130 and below the chaps sieve 140. The second conveyor 220, which is installed on the lower frame 250 and transports the grains and foreign substances filtered by the grain sieve 130 and the chaps sieve 140 to the grain plate 110, and the lower frame 250 A tuyere (230) installed in the front that blows wind to the sorting pin (120) and the chaff sheave (140), and a combination of the sorting pin (120) installed in the rear upper part of the lower frame (250) that shakes it up and down. It includes device 240.

This normal type combine harvests pulses such as wheat and barley with a dedicated cutter, threshes them, and then selects them and discharges them.

Here, the sorting unit (A) sorts the grains through the sorting device 100. When the grains and gumbul are mixed after threshing, the grain plate 110 uses the density difference to position the grains at the bottom. Let the black pepper float on top. At this time, the gum is moved to the chapsieve (140) by the wind of the tuyere (230), and the grains are moved by the combination of the sorting pins (120).

The combination of the sorting pins 120 uses the wind of the tuyere 230 and the shaking caused by the shaking device 240 to cause the grains to fall to the lower grain sieve 130, and the black beans are moved to the chaf sieve 140. Chaf The sieve 140 uses the wind from the tuyere 230 to select the remaining grains in a large amount of gumball and transfers them to the second conveyor 220, and discharges the gumbul to the rear.

The grains that fall below the sorting pin (120) are selected by the grain sieve (130) and fall to the first conveyor (210), and the rest are transferred to the second conveyor (220). The first conveyor 210 transfers the selected grains to the grain tank, and the second conveyor 210 transfers the grains and foreign substances transferred from the grain sieve 130 and the chaps sieve 140 to the grain plate 110. Go through a re-selection process.

However, in the sorting device provided in the sorting part of the conventional combine described above, the grain sieve is fastened to the fastening bolt on the sorting device frame, so if the grain sieve needs to be replaced depending on the type of crop, the sorting device must be separated from the lower frame assembly. There is a problem in that it takes a lot of time and effort to replace the grain sieve because the grain sieve must be separated from the sorting device frame, a new grain sieve is attached, and then the sorting device has to be slid back to the lower frame assembly.
