Description

[0001] Grain storage tank lifting device for combines [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain storage tank elevating apparatus for a combine, and more particularly, to a grain storage tank elevating apparatus for harvesting cereals from a grain storage tank, The present invention relates to a grain storage tank elevating apparatus for a combine capable of controlling the elevation of a grain storage tank.

The "combine" runs on the farmland, harvesting and sorting the grain of rice, barley, wheat, soybean, grass seeds, etc., and storing the selected grain in the tank as it is, It is a grain harvesting machine that can be packed in a bag at the same time so that transportation convenience can be achieved.

The combine is available for harvesting various grains, so there are many kinds, but generally it is divided into self-deformation type and normal type.

It is a combine that feeds only beak but only ears to the threshing machine until the base of the grain. The structure consists of a harvesting section for raising the fallen grains, a conveying device for conveying the grains to the threshing and sorting section by a belt or a chain, a threshing section for excavating an automatic thresher, And a traveling section (usually an endless track is used) for moving the body of the storage section and the combine.

The width of the bed is 60 ~ 120cm, and for 2 trillion (60cm width), the internal combustion engine is equipped with about 15PS and 1 ~ 2 people work. The length is 2 to 2.5 m, the weight is 500 to 800 kg, and the running speed is 1 to 2 km / h. Work efficiency is influenced by the size of the sickle area, such as the driveway of the combine, turning part. In a farm which is divided into 10a, about 6% of the area should be sickled. In this case, the comb can be operated at 6a / h with a width of 60cm and 12a / h with 120cm. However, if the grain falls more than 30 °, the work efficiency is lowered, and the loss and damage of the grain increase.

The common type combine is a large combine mainly used in the West. The stem and the ears are inserted into the thresher at the same time. The structure is similar to the self-de-molding, the width is 2 to 4 m, and is pulled by a tractor or operated by an internal combustion engine of 30 to 90 PS. Length 7 ~ 10m, weight 3 ~ 6t, 1 ~ 2 people operate.

Driving speed is 1 ~ 2km / h when harvesting rice and 3 ~ 4km / h when harvesting. The work efficiency depends on the farm, cultivation conditions, grain moisture, graininess, machine adjustment, operation technique, etc., and the combin with 2.5 m width is usually 15 ± 5a / h, 6 ± 2%, and grain damage is about 4 ± 2%.

Meanwhile, in the conventional combine, the grains sorted and sorted after harvesting are directly put into the bag so that they can be packed immediately. However, in order to put the grain directly into the bag, the driver who drives the combine, Two workers must perform grain harvesting at the same time because they need workers.

However, due to the recent rapid decrease in the agricultural population, it has become common practice to use a minimum number of workers for various kinds of operations using an automated machine. After harvesting, threshing and sorting the grains using a combine as in the conventional method, , It is not possible to carry the bag containing the grains to the combine. Therefore, when the grains are being harvested, the bags packed with the grains are put down on the farm land and collected after the harvesting of the grain is completed. There is a problem that it is troublesome and inconvenient to carry.

Therefore, most combine harvesters are harvested, threshed and sorted, and then the grains are stored in a grain storage tank provided in the combine. When the grain storage tank is filled, the combine is moved to a separate place, By discharging the grains stored in the tank and transferring them to a unit or storing them in a separate storage facility, the grain harvesting operation can be performed with a minimum number of persons and the convenience of transportation and storage of harvested grains can be improved.

The bottom of the grain storage tank is formed into a hopper shape so that the grains stored in the grain storage tank can be easily discharged, and the grain outlet is formed at the lower end thereof. Therefore, since the height of the grain discharge outlet discharged from the grain storage tank is low, it is necessary to separate the grains discharged from the grain outlet of the grain storage tank to the desired height in order to transfer the grain to a separate storage facility or transportation vehicle There has been a problem that the conveyance of the grain is troublesome and inconvenient because of the use of the conveying means.

Also, when the grain stored in the grain storage tank is directly transferred to a certain unit, the height of the grain outlet of the grain storage tank is too low, and it is difficult to transfer the grain to the large and high- There is a problem in that the transportation, storage and packaging of the grain discharged from the grain storage tank is cumbersome and inconvenient because it takes more work time and labor to transport the grain into the bag.

As described above, in order to solve the problem caused by the position of the grain outlet of the grain storage tank being too low, the grains stored in the grain storage tank are forcibly pushed upward by using a transfer screw (auger) However, in the case where grains stored in the grain storage tank are forcibly pumped by using the feed screw to discharge grains by using the grain discharge pipe, the final discharge of the grain discharge port It is possible to carry out the transportation, storage and packing work of the grain easily while increasing the height. On the other hand, in the process of plowing the grain stored in the grain storage tank, grains are caught between the transport screw and the grain discharge tube, In addition to frequent occasions, it is important to ensure that the grains stored in the bottom of the grain storage tank are completely discharged There was a difficult issue.

The present invention relates to a gravity storage tank lifting device for a combine, which is provided to solve the above-mentioned problems of the prior art, and includes a base frame 10 installed on an upper portion of the combine; A guide rail 20 installed at right and left sides of the base frame 10 upright at regular intervals; A roller 301 which is in close contact with the inside of the guide rail 20 is installed on both sides and a grain storage tank 50 is fixed to an upper portion of the roller 30 so as to move up and down together with the grain storage tank 50 along the guide rail 20 An ascending / descending member 30; And elevating means (40) provided on both left and right sides of the base frame (10) to raise and lower the elevating body (30) up and down, thereby facilitating height adjustment of the grain storage tank, Can be easily discharged without damaging at a desired height, thereby achieving the objective of facilitating transportation, storage, packaging, and the like.

As described above, since the height of the grain storage tank for the combine according to the present invention is easily adjusted, it is possible to discharge the grain to a desired height when the grain is discharged from the grain storage tank for storing the grain after harvesting the grain It is possible to easily carry out the harvesting, storage and packing of the harvested cereals, as well as allowing the grains stored in the grain storage tanks to be naturally discharged by their own weight without any separate discharge means, thereby discharging the grains stored in the grain storage tanks It has the effect of preventing the damage of grain in the process.
