Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a protective device for a secondary Kara Minoh in a threshing machine, and more specifically, a first spiral and a second spiral located below a grain swinging sorting body. In the threshing machine, which has an additional Kara Minor between
A horizontal frame arranged in the left-right direction of the combine main body frame for supporting and supporting the threshing machine, which faces the lower side of the sub Kara, and a protection apparatus for the sub Kara in the threshing machine arranged in the axial direction of the sub Kara. is there.

(Prior art) The secondary Kara Minor is to select the second and third products by wind-selecting the cutting culms, twigs, straw debris, etc. that could not be completely sorted on the grain swinging sorting body. It is installed in, but this sub Kara sucks the wind from below and uses this sucked wind as the sorting wind, so the lower side has an open suction port.

However, the conventional combine main body frame that supports and supports the thresher does not block the space between the lower part of the sub-tang and the paddy field, and is constructed in an open state directly, so when harvesting work in wetlands, etc. When dirt, mud, surface straw, and cut straw with a cutter are carried around by the crawler, these foreign substances enter through the suction port on the lower side of the sub Karako and the mud and cut straw collide with the blades, or the long straw rotates. There was a problem that it could wind around the shaft and deform and damage the auxiliary Kara.

(Problems to be Solved by the Invention) In view of the above situation, the present invention was devised to eliminate conventional problems, and the purpose thereof is to combine a thresher with a supporter. The horizontal frame, which is arranged in the left-right direction of the main body frame, faces the lower side of the sub Kara and is arranged in the axial direction of the sub Kara so as to block the space between the lower Kara, the lower side and the field. Therefore, even if the crawler carries mud, long straw, and cut straw with a cutter in the process of harvesting in wetlands, etc., the combine main body frame prevents these foreign substances from entering from the suction port on the lower side of the sub Kara Minoh. It prevents the deformation and damage of the secondary Kara-ko, and keeps the wind-selection effect of the secondary Kara-ko in the best condition at all times. Can be selected accurately The combine main body frame, which is located in the axial direction of the sub-tanko and faces the lower side, has the function as a beam, and even if the reinforcing frame is not provided by a separate member, the entire combine main body frame There is an attempt to provide a protection device for the sub-tangle in the thresher that can improve the strength of the threshing machine.

(Means for Solving Problems) In order to solve the above problems, the technical means adopted by the present invention is that a grain swinging sorting body is erected in the sorting air passage so as to be swingable in the front-back direction, and the grain swinging is performed. In a threshing machine in which a sub Kara Minor is disposed between the first spiral and the No. 2 spiral located below the sorting body, the sub Kara Minor is formed with a cross-flow fan having a suction port on the lower side, It is characterized in that a horizontal frame arranged in the left-right direction of a combine main body frame on which a thresher is mounted and supported faces the lower side of the sub Kara and is arranged in the axial center direction of the sub Kara.

(Operation) Therefore, according to the present invention, since the horizontal frame in the left-right direction, which faces the lower part of the sub-tara and is arranged in the axial direction, blocks the lower part of the sub-tart and the rice field, the wetland Even if the crawler carries mud, long straw, cut straw with a cutter, etc. in the process of harvesting at the etc., these foreign substances are prevented from entering through the suction port on the lower side of the sub Kara, and deformation of the sub Kara, Damage is prevented. For this reason, the wind-selection effect of the sub-karato is always kept in the best condition, and the hot-cutting culms, twigs, straw wastes, etc., which could not be completely sorted on the grain swing-sorting body, are wind-sorted to produce the second and third crops. It can be sorted as a gift.

Without falling, it surely falls into the second flow plate 23a and is collected, and only the straw dust having a small specific gravity is discharged from the dust exhaust port 33 to the outside of the machine by the suction air of the suction fan 27.

By the way, when the above harvesting work is performed in wetlands, etc., mud, surface straw, and cut straw by the cutter are conventionally carried around by the crawler in the process of the work, and the mud and cut collide with the blade of the sub Kara 29. There was a problem of deforming and damaging the sub Kara 29, due to the long straw being wrapped around the rotating shaft.
In the present invention, since the horizontal frame 37b of the combine main body frame 37 is arranged below the sub-tower 29 in the axial center direction, these foreign matters are blocked by the horizontal frame 37b and the sub-tower 2
9 Intrusion from the lower suction port is blocked. For this reason, the deformation and damage of the sub Kara 29 induced by the invasion of foreign matter is completely prevented, and the best cutting action is always maintained and the grain cutting that cannot be completely sorted on the grain swing sorting body 14. Grain culm,
It is possible to select twigs, straw waste, etc. by wind and sort them into second and third items.

(Effects of the Invention) In short, the present invention installs the grain swinging sorting body in the sorting air passage so that it can swing forward and backward, and the first spiral and the second spiral located below the grain swinging sorting body are arranged. In a threshing machine in which a sub-tangle is arranged between, the sub-tangle is formed by a cross-flow fan having a suction port on the lower side, and is arranged in the left-right direction of the combine body frame supporting and supporting the threshing machine. Since the horizontal frame is placed under the sub Kara and is disposed in the axial direction of the sub Kara, the following remarkable effects are obtained.

That is, the horizontal frame between the suction port on the lower side of the sub Kara and the rice field faces the bottom of the sub Kara so that it is completely blocked along the axial direction of the sub Kara. Even if the crawler carries mud, long straw, cut straw with a cutter, etc. in the process of working, it surely prevents these foreign substances from entering from the suction port on the lower side of the sub Kara so that the sub Kara is not deformed or damaged. It is possible to prevent it in advance, always keep the wind selection action by the secondary Kara Minor in the best state, and accurately select the second and third items that could not be selected on the grain swinging selection body, The horizontal frame also has a function as a beam because it is arranged in a direction orthogonal to the vertical frame, and improves the strength of the whole combine main body frame even without providing a reinforcing frame as a separate member. be able to.
