Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a threshing net support device for supporting a threshing net of a threshing machine, and can be used in threshing devices such as combines and harvesters.

Conventional technology There is a known technology in which three support plates supporting the 1152 yen 2 net at the bottom of the threshing room are provided below the threshing net for the front, rear, and middle portions, and are attached to the machine frame. (Utility Model Application No. 63-181230).

Problems to be Solved by the Invention In the threshing room configuration in which the threshing net is supported by a support plate attached to the machine frame, the support plate can be formed thin so that it does not easily interfere with threshing and sorting. However, since the structure of this support plate is weak and easily distorted, its rigidity is low, making the entire threshing machine unstable.

The present invention solves such defects by increasing the rigidity of the support plates while keeping the separation interval between the support plates as wide as possible without restricting them.

Means for Solving the Problems In order to achieve the above object, the present invention takes the following technical measures. , Rf of a guide plate that is supported by the front, rear and middle support plates installed on the machine frame, and extends between these front and rear support plates and the middle support plate to guide the dropping of the threshed grains leaking from the H'rl 'fU net. A threshing net support device for a threshing machine has a fixed rear end.

Operation The f152 grain operation can be carried out by rotating the handling cylinder in the threshing chamber. When the +1152 grains leak from the threshing net, they are guided by the guide plate and fall to a predetermined location in the sorting section below. This guide plate has both front and rear ends connected between the front support plate and the middle support plate, or between the middle support plate and the rear support plate, so that each support that supports the threshing net There is little distortion in the front-back direction of the board, and the rigidity is high.

EXAMPLES Below, examples of this research will be explained based on the drawings. The threshing machine frame forms a sorting chamber 2 in which a swinging sorting shelf 1 is mounted on the lower part, and a threshing chamber 5 in which a handling drum 3 is mounted on a handling drum shaft 4 in the upper part.

One part of the right wall plate 9 has a supply port 11 to a discharge port 1.
A shell culm transfer port 13 is provided to communicate between the two.

Along this grain culm transfer port 13, a grain culm transfer device 14 is provided to transfer the stock part of the husk while holding it.

The threshing room 5 is provided with a threshing net 15 on the lower circumferential surface, the upper side is covered with a threshing cover, and the handling drum 3 is mounted on a rotating white flower by the handling drum shaft 4 between the front and rear wall plates 6 and 7 to transmit power. Rotate by. At the upper end of the left wall plate 8, there is provided a processing chamber 7 with a processing net 16 stretched over the lower circumferential surface, and the processing material supplied from the rear end of the threshing chamber 5 and the second processing grain lifting machine is provided. In response to this, the processing cylinder 19, which is rotated and transmitted around the processing cylinder shaft 18, performs threshing processing.

The support plates are provided to support the lower side of the threshing net 15 in the threshing room 5, and include a front support plate 20 on the supply port 11 side, a middle support plate 21 that supports the front and rear central portions, and 12 discharge ports. The left and right ends are integrally fixed to the left wall plate 8 and right wall plate 9 by welding or the like, and the lower surfaces of the threshing net 15, processing net 16, etc. are supported along the upper edge. . These threshing net 15, processing net 16, etc. are provided so as to be replaceable.

The front support plate 20 is constituted by the lower edge of the supply port 11 of the front wall plate 6.

The guide plate consists of a partition guide plate 23 provided on the lower side of the threshing net 15 along the direction of the handling cylinder axis 4, and a gathering guide plate 24 provided below the processing chamber 17 and inclined toward the center. The plates 23 and 24 are provided between the front support plate 20 and the middle support plate 21 and between the middle support plate 21 and the rear support plate 22.

The partition guide plate 23 reflects the threshed grains that are threshed by the rotation of the handling cylinder 3 and is scattered to the lower left side under the threshing net 15 directly below, thereby dispersing the threshed grains on the upper surface of the swing sorting shelf l. It is.

In addition, the shifting guide plate 24 receives the threshed grains that leak and fall between the threshing net 15 and the processing net 6, and guides the threshing grains downward from the left wall plate 8 to the center side, so that the threshing grains are oscillated. This prevents the sorting shelf 1 from shifting to a position closer to the right wall plate 9.

Each of these guide plates 23 and 24 is arranged between the 6jf support plate 20, the middle support plate 21, and the rear support plate 22, and is connected to each other by attaching them with fasteners 25 such as bolts and nuts. . Further, the upper edge of the partition guide plate 23 may be configured to support the threshing net 15, or may be formed with an appropriate distance from the threshing net 15. Further, the shifting guide plate 24 is fixed to the left wall plate 8 with bolts 26.

The swinging sorting shelf 1 receives the threshed grains that have leaked through the threshing net 15, the processing net 16, etc., and transfers and sorts them while swinging.A receiving plate 27 is provided at the front position on the supply side 11. , a sorter 1128 is provided in the middle portion, and a stroke rack 29 and the like are provided in the rear end portion. The sorting chamber 2 of the lower example of the swinging sorting shelf 1 has a sorting air path through which sorting air is passed from the front windshield to the rear dust outlet. 30 is a feed funnel on the front side of the feed-11.

The grain culm transferred by the grain culm transfer device 14 is fed to the supply port 11.
While the grain is supplied to the threshing room 5 and discharged from the output 12, a harvesting action is performed by the simultaneous rotation of the handling cylinder 3. A part of the grain leaked from the threshing N415 becomes scattered to the left, but is reflected by the partition guide plate 23 and falls downward. In addition, the threshed grains leaking from the right side of the threshing room 5, the processing room 7, etc. are partially guided down on the gathering guide plate 24 and fall to the left and right center portions of the swinging sorting shelf l. .

When the threshed grains are guided down by the guide plates 23 and 24 in this manner, they are received by the swing sorting +till l and are swing sorted. Further, the first grain sorted in the sorting air passage under the swinging sorting shelf l is taken out of the machine by a grain frying machine, and the second grain is transferred to the processing chamber 17 for processing.

The threshed grains discharged from the discharge port 12 are received by the upper part of the straw rack 29 at the rear of the shaker f//1 sorting shelf 1, and are shaken and sorted, and the scraps and waste are removed from the rear end. be discharged.

When the lid grain is operated by the rotation of the handling cylinder 3, the l1ti
W This may cause twisting or distortion in the machine frame, but the support plates 20, 21, and 22 on the lower side of the threshing m15 are thin plates, but are continuously fed by the partition guide plate 23 and the shifting guide plate 24. In addition to increasing the rigidity and firmly supporting the threshing net, the configuration of the threshing room can also be strengthened.

Effects of the Invention Since the present invention has the above-mentioned configuration,
If the following technical effects are achieved. That is.

When the threshing action is performed by the rotation of the handling cylinder in the threshing chamber, the threshed grains that leak through the threshing net are guided down by the lower guide plate and dropped into a predetermined position in the sorting section. While the guide plate itself guides the fall, each support plate is reinforced, and the interval between leakage sorting of threshed grains in the threshing net is maintained in a rightward movement, thereby maintaining the stability of the threshing net or the threshing room.
