Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a grain frying device and can be used in a combine harvester, a harvester, etc.

Prior Art In a grain lifting device in which a discharge cylinder is connected to the upper end of the grain lifting cylinder and the grains are discharged from the discharge cylinder into grain bags and packed into bags, There is no one that has a scraping body with a smaller diameter than this helical diameter on the helical shaft.

Problems to be Solved by the Invention When the grains fried by the grain lifting cylinder are received from the discharge cylinder into the grain bag and then packed into bags, it takes time to replace the grain bag, and the replacement of grain bags is delayed. Then, the grain bags are filled to the brim with grains until they reach the end of the discharge tube, and the grains gradually accumulate in the discharge tube.At the end, the grains clogged in the discharge tube make it impossible for the frying shell helix to rotate. There are cases. These clogged grains tend to collapse in the lower part of the discharge tube near the take-out port, but in the upper part of the grain-lifting helical shaft, the grains fried by the grain-lifting helix are pressed against the inner wall of the discharge tube. Since there is no space, it is difficult to collapse, and it is difficult to remove the clogged grains.Furthermore, it takes many man-hours and is troublesome to remove the clogged grains from the grain lifting cylinder.

In view of this, the present invention provides a scraper on the helical shaft for frying grains in the discharge cylinder to scrape out the grains, making it easier for the grains to accumulate in the discharge cylinder, and when clogging occurs.

The purpose is to form a portion with a low degree of grain clogging around the helical shaft so that it can easily fall down, so that the grain clogging can be easily removed.

Means for Solving the Problems This invention provides a grain lifting cylinder (2) having a grain lifting helix (1) inside.
There is a discharge cylinder (4) with an outlet (3) at the bottom at the upper end.
A discharge tube (4) facing the fried grain helix (1) is provided in series.
) between the receiving part (6) of the helical shaft (5) and the terminal end of the fried grain helix (1) along the outer periphery of the helical shaft (5). A scraping body with a smaller diameter than
7) is provided.

The working grains of the invention are fried in the grain lifting tube (2) by the grain lifting helix (1) and taken out from the outlet (3) below the discharge tube (4). The grains fried by the grain frying helix (1) remain in the discharge tube (4) without being scraped by the scraper (7). When the grains are retained in the discharge tube ζ (4) inner metal body, the scraping body (7) is inserted between the terminal end of the grain frying helix (1) and the helical shaft (5) and the receiving part (6).
The grains around the rotating part are scraped out by the scraping body (7).

Effects of the invention The fried grains have a scraped body (with a smaller diameter than the fried grain helix diameter).
Since the grains are scraped out by the scraper body (7), they tend to accumulate in the discharge tube (4) without being blown away, and the grains staying in the discharge tube (4) are scraped out by the scraper body (7). The degree of clogging of grains around the helical shaft (5) is low, and even if the grains are clogged, when the grains are taken out from the outlet (3),
Since the grains in the upper part of the discharge tube (4) are easily scraped out by the rotation of the scraper (7) and fall down, the clogging of the grains can be easily cleared.

Embodiment In the example shown in Fig. 1, the running vehicle body (8) is provided with a control handle (11) on an operation frame (10) that stands upwardly at the rear of the chassis (9), and a running device (12) at the bottom. A threshing device (13) is removably mounted on the top.

A traveling device (1) is installed at the rear of the frame below the chassis (9).
A transmission case (14) for transmitting 2) is attached, a prime mover (15) is mounted on the upper surface of this transmission case (eye), and a bag holder (1B) is provided at the rear.

The threshing device (13) is provided with a threshing chamber in which a handling cylinder (17) is housed in the upper part, and a clamping rod (18) and a foot chain ( 1
9). At the bottom of the threshing room, there is a handling barrel (17).
There is a sorting room that receives the threshed grains that leak out from the threshing room and separates them into grains and straw waste.At the bottom of this sorting room, there is a first gutter (2θ) equipped with a spiral. There is. At the rear of the threshing room, there is a wind sorting room for sorting the straw waste sorted in the sorting room, and a second processing cylinder is installed below this wind sorting room.

A grain lifting tube (2) extending rearward and diagonally upward is communicated with the terminal end side of the first gutter (20), and a discharge tube (4) is communicated with the outlet of the grain lifting tube (2). It is set up. The discharge cylinder (4
) forms an outlet (3) (3) that branches downward into two front and rear branches, and the front outlet (3) is provided with an opening/closing shutter.
The outlet (3) on the rear side is for overflow. A bag opening holder (21) is provided below the outlet (3) (3), and a paddy bag (22) (22) is attached to this bag opening holder (21).
...is hanging.

A helical shaft (5) to which the grain lifting helix (1) is attached is internally supported in the grain lifting cylinder (2), and this helical shaft (5) is connected to the helical shaft of the first gutter (20) through a bevel gear. The structure is such that the power is transmitted by

The part of the helical shaft (5) that protrudes from the grain lifting cylinder (2) is cut off from the grain lifting helix (1), and the tip of this helical shaft (5) is attached to a receiving part provided on the inner wall of the discharge cylinder (4). It is supported by (6). A scraping body (7) is provided in the axial direction along the outer periphery of the helical shaft (5) between the terminal end of the grain frying helix (1) and the receiving part (6) of the helical shaft (5). . The scraping body (7) has a circular cross section, and the outer diameter of the cylindrical shape formed by the scraping body when the helical shaft (5) rotates is smaller than the outer diameter of the grain frying helix (1). There is.

When the motive power a (15) transmits power to each part and supplies the cut husk culm to the foot chain (19), the husk culm is conveyed by the pinching rod and then threshed by the handling drum (17). . This threshed grain leaks from the threshing room and is separated into grains and straw waste in the sorting room, and the straw waste is separated in the wind sorting room and discharged outside the machine.

The grains fall into the first gutter (20), are transferred horizontally by the helix, are transferred diagonally rearward and upwardly by the grain lifting helix (1), are retained in the discharge tube (4), and are transferred to the front outlet (3). When the shutter is opened, the grains are stored in the paddy bag (22).

When the paddy bag (22) is filled with grains, they are stored in the paddy bag (22) through the overflow outlet (3) on the rear side, but the paddy bag (22) at the front side outlet (3) must be replaced. If you take a long time to replace the paddy bag (22) or forget to replace the paddy bag (22), the paddy bag (22) at the front and rear outlet ports (3) (3) will be completely filled and the discharge tube (4) The grains also stay inside and eventually become clogged, making it impossible for the grain frying helix (1) to rotate. Even in this clogged state, the grains are scraped out by the scraper (7), so the degree of clogging of grains around the helical shaft (5) is low, and when the filled paddy bag (3) is replaced, Tube (4)
As the grains in the inner lower part collapse, the grains around the helical shaft (5) also collapse. Therefore, even if grains become clogged, the grain lifting helix (1) can be rotated without removing the grains in the grain lifting barrel (2), and the grains to be fried can be removed from the scraping body (
7) scrapes out the grains that are clogged in the upper part of the discharge tube (4), and the clog is removed. Further, the scraping body (7) can protect the helical shaft (5) receiving portion (6) from the pressure of the fried grains by the fried grain helix (1).
