Description

The filtering net removable device of threshing machine}

The present invention relates to a threshing machine that automatically threshes mixed grains such as beans, sorghum, millet, and millet. More specifically, it has countless discharge holes to separate unprocessed grains and threshed grains according to the type and size of the grains to be threshed. It relates to a filtering net attaching and detaching device for a threshing machine that allows the formed filtering net to be easily replaced without using a separate tool.

Generally, in order to obtain mixed grains such as beans, sorghum, millet, and millet produced in rural areas, threshing is required. When threshing these grains, the ears at the ends of well-fruited stems are cut off, dried, and then threshed using a threshing machine. Miscellaneous grains are obtained.

As the mixed grains are threshed in this way, foreign substances contained in the mixed grains (finely broken bean pods, sandy soil, etc.) are removed from the shaker, and then the threshed grains move to the lower part along with the filter and pass through the discharge hole formed in the filter net. However, only miscellaneous grains are sorted out as they come out through the discharge hole formed in the strainer.

Figure 1 is a perspective view showing a conventional soybean threshing machine, Figure 2 is a longitudinal cross-sectional view of Figure 1, and Figure 3 is a perspective view showing the soybean outlet side. The driving of the motor 4 on the upper part of the main body 3 is a known power transmission means. A drive shaft (5) that rotates as it is transmitted is installed, and a shaft (6) that rotates in the opposite direction to the drive shaft is installed directly below the drive shaft, and a roller (7) is fixed to the shaft (6). A cylindrical net body (8) is placed on the net, and a spiral rail (9) is fixed inside the net body (8) along the direction of rotation.

Therefore, as the bean stalks are threshed while the net sieve (8) rotates in the opposite direction to the rotation direction of the drive shaft (5), the threshed beans and bean stalks (bean stalks and bean pods) are transported along the rail (9) to the bean stalk discharge port. Foreign substances such as threshed beans and finely broken bean stalks and bean pods pass through the screen and fall freely downward.

On the outside of the drive shaft 5, a plurality of striking bars 19 are installed to strike the bean stem according to the rotation of the drive shaft, so that the bean is formed on one side of the cover 22 that is installed to be openable and closed on the main body 3. As the bean stalks are introduced through the bean stalk inlet 23, the striking bar 19 is designed to thresh the beans by hitting the bean stalk, and on the other side of the bean stalk inlet 23, the bean stalk is discharged to the outside of the main body 3. A distance-free outlet 24 is formed.

Meanwhile, one end of the connecting rod 33 is eccentrically installed on the drive shaft 5 that rotates according to the driving of the motor 4, and the other end of the connecting rod is connected to the rod 34 installed on the main body 3. ), the other end of the rod is connected to the rocking body 32 installed at an angle so as to be located at the lower part of the net body 8, so that when the drive shaft 5 rotates due to the driving of the motor 4, the rocking body Since the sieve 32 removes foreign substances while making a oscillating motion as if shaking the sieve, only the beans and radish are moved downward.

A plurality of discharge holes 35 are formed at the end of the rocking body 32, and a cover 36 is formed on the upper end of the rocking body.

On one side of the lower part of the main body (3), while foreign substances such as beans, bean stalks, and bean pods are lowered along the inclined rocking body (32), wind pressure is used to force foreign substances such as bean stalks and bean pods of low specific gravity to be discharged to the outside. The fan 39 is installed to be surrounded by the fan housing 45.

However, in this conventional threshing machine, the discharge hole for sorting out the grains and beans is formed integrally at the bottom of the shaker, so the operator has to replace the shaker in the main body every time the type and size of the mixed grains to be threshed change, which reduces work efficiency. A problem occurred.

In addition, since the bottom of the rocker was open, the threshed mixed grains fell freely along with the mugori after foreign substances were filtered out of the shaker, and were unable to escape through the discharge hole. A problem also occurred where they were discharged to the outside of the main body along with the mugori due to gravity.

The present invention was devised to solve such problems in the prior art. The purpose of the present invention is to form a filtering net with numerous discharge holes separately from the rocking body so that the filtering net can be attached to and detached from the main body without using a separate tool. there is.

Another object of the present invention is to rotatably install a cover on one end of the strainer to close the zero-distance outlet when threshing mixed grains to prevent freely falling beans from being thrown out of the main body by gravity, and to replace the cover when replacing the strainer. The purpose is to rotate the sieve net so that one end of the sieve net is exposed to the outside, making it easy to replace the sieve net.

According to an aspect of the present invention for achieving the above object, in the strainer mesh attaching and detaching device of a threshing machine provided with a strainer net formed with numerous discharge holes having a predetermined diameter, through holes are formed on both sides of the main body where the strainer net is installed, respectively, A permanent magnet consisting of a small diameter part exposed to the inside of the main body through each hole and to which the upwardly bent piece of the catching net sticks, and a large diameter part formed on the outside of the small diameter part and sticking to the main body, is installed in the catching net to the inside of the main body. Upwardly bent pieces that stick by the magnetic force of the exposed small diameter portion are formed on both sides, and a stopper is formed to limit the insertion depth of the filtering net. When the stopper of the filtering net is pushed until it touches the upward bending part of the main body, the filtering net's stopper is formed on both sides. A strainer mesh detachment device for a threshing machine is provided, wherein the tip is inserted into the lower end of the rocking body formed inside the main body, and the upwardly bent piece is supported by sticking to the small diameter portion of the permanent magnet.

The present invention has the following advantages over the prior art.

First, if you open the cover and pull one end of the strainer outward, the strainer will fall off the permanent magnet and the strainer will be separated from the main body. If you simply push a new strainer into the body, the upwardly bent portion of the strainer will stick to the permanent magnet and be replaced. As the work is completed, the strainer can be replaced without using separate tools depending on the type and size of the grains. As a result, not only is the population gradually aging, but work efficiency due to the use of thresher is reduced in rural areas where labor is scarce.

Second, a cover is rotatably installed at one end of the strainer through which the mugeri is discharged, so even if the beans fall freely along with the mugori, they do not get caught in the cover and bounce out of the main body, so there is no need for separate sorting work.

Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. The present invention may be implemented in many different forms and is not limited to the embodiments described herein. Please note that the drawings are schematic and not drawn to scale. The relative dimensions and proportions of parts in the drawings are shown exaggerated or reduced in size for clarity and convenience in the drawings, and any dimensions are illustrative only and are not limiting. And for identical structures, elements, or parts that appear in two or more drawings, the same reference numerals are used to indicate similar features.

Figure 6 is an exploded perspective view showing the main part of the present invention, Figure 8 is a longitudinal cross-sectional view of the strainer of the present invention when it is mounted on the main body, and Figure 9 is a longitudinal cross-sectional view showing the permanent magnet of the present invention, and the present invention is a strainer net (110). At least one through hole 101 is formed on both sides of the main body 100, and a permanent magnet 120 as shown in FIG. 9 is magnetically attached to each through hole 101.

The permanent magnet 120 applied to the present invention includes a small diameter portion 121 that is exposed to the inside of the main body 100 through the through hole 101 and allows the upwardly bent piece 111 of the strainer 110 to adhere to the above-described portion. It consists of a large diameter part 122 formed on the outside of the small diameter part 121 and attached to the main body 100.

When the small diameter portion 121 of the permanent magnet 120 is inserted into the through hole 101 formed in the main body 100, the large diameter portion 122 of the permanent magnet 120 sticks to the outside of the through hole 101 and does not fall off.

In Figure 6, which shows an embodiment of the present invention, the through hole 101 in which the permanent magnets 120 are installed on both sides of the main body 100 is 2 so as to ensure that the magnetic force is applied to the upwardly bent piece 111 of the filter net 110. They are shown one by one, but it is okay to form only one.

Upwardly bent pieces 111 that are attached by the magnetic force of the small diameter portion 121 are formed on both sides of the strainer 110 that is detachably installed on the main body 100, and the strainer 110 is located on the front of the strainer 110. The stopper 112, which limits the insertion depth, is bent downward, so that when the stopper 112 of the strainer 110 is pushed until it touches the upwardly bent portion 102 of the main body 100, the strainer 110 is bent. As the tip is inserted into the lower end of the rocking body 130 formed inside the main body 100, the upwardly bent piece 111 is supported by sticking to the small diameter portion 121 of the permanent magnet 120.

Meanwhile, a cover 140 is rotatably installed on the main body 100 located at the end of the strainer 110.

The operation of the present invention is explained as follows.

First, when the filtering net 110 having numerous discharge holes with a predetermined diameter is mounted on the main body 100, the upwardly bent pieces 111 formed on both sides of the filtering net 110 are connected to the small diameter portion 121 of the permanent magnet 120. Since it is attached to the main body 100, the strainer net 110 does not move.

In this state, when the soybean threshing operation is performed, the cover 140 closes the lower end of the strainer 110, so even if the soybeans from which foreign substances are removed while being threshed and pass through the shaker 130 fall freely by gravity, the cover 140 ) and is not thrown out of the main body 100, thereby improving workability compared to a conventional soybean thresher.

In this way, if the size of the beans changes while threshing the mixed grains or the type of the mixed grains changes, the strainer 110 mounted on the main body 100 must be removed and replaced with a new strainer.

To do this, open the cover 140 that was closing the lower end of the strainer net 110 as shown in FIG. 6 and then pull it forward while holding the stopper 112, so that the upwardly bent piece 111 of the strainer net 110 is permanently bent. Even if it sticks to the small diameter portion 121 of the magnet 120, the force pulling the strainer 110 is large, so the strainer 110 is separated from the main body 100 as shown in FIG. 6, making it possible to separate the strainer 110. .

At this time, the large diameter portion 122 of the permanent magnet 120 is attached to the main body 100 and is not separated from the main body 100.

Accordingly, if the operator selects a strainer 110 with a discharge hole of an appropriate size according to the type and size of the coarse grain to be threshed and inserts it so that the tip of the strainer 110 is caught on the bottom of the rocker 130 as shown in FIG. When the stopper 112 is pushed until it is caught in the downwardly bent portion 102, the upwardly bent pieces 111 formed on both sides of the strainer 110 stick to the small diameter portion 121 of the permanent magnet 120, so they can be used with drivers, etc. It is possible to replace the strainer 110 without using a separate tool.

Afterwards, it is understandable that threshing work can be continued by closing the opened cover 140.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that it can be implemented in other specific forms without changing the technical idea or essential features. will be.

Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive, and the scope of the present invention described in the detailed description is indicated by the claims described later, and the meaning and scope of the claims. The scope and all changes or modified forms derived from the equivalent concept should be construed as being included in the scope of the present invention.
