Description

Automatic threshing machine for shaking grains

This technology relates to an automatic threshing device for shaking out grains by striking grain located on the ground.

As the rural population in our country rapidly decreases with the progress of industrialization, agriculture is also becoming mechanized. In particular, farm management machines for shaking out grains from grains ('soybeans' are listed as an example below) are small and small. Because it is inexpensive and easy to operate, it is widely distributed to each farm.

In general, almost all farms are farming soybeans, which are basically a type of grain. When soybeans are harvested, the soybean stems are cut and gathered in one place to be dried. When drying is completed, they are threshed to remove the bean kernels in the pods, and the separated soybean kernels are then harvested. Separate the bean pods and bean stalks.

In the past, soybeans were dried well and then threshed using a flail, and many farms still adhere to this traditional method. However, as mechanization is gradually progressing in the agricultural field, the number of farms that thresh soybeans by machine is rapidly increasing, and accordingly, the need for farm management equipment is increasing. Along with this, bean threshing machines (or threshing machines) are becoming popular.

Here, the threshing machine is a rotary drum equipped with a threshing member installed on the upper part of the perforated receiving plate of the main body, and provided with a crop input part on one side and a distanceless discharge part on the other side, so that the crops are put into the crop input part, thereby rotating the crop. It refers to a machine that allows the crops to be threshed by the threshing member of the drum and fall into the perforated part of the receiving plate, and at the same time, the stems of the crops, etc., are discharged through the distanceless discharge part.

However, although such a thresher is convenient, it is very expensive, so it is a great burden for farmers to purchase a thresher. Recently, the supply of a thresher that is inexpensive and can easily remove beans from the soybean stalk has become an urgent problem.

In addition, when describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof is abbreviated or omitted.

Hereinafter, an automatic threshing machine for shaking grains according to the present invention (hereinafter simply referred to as a 'throwing machine') will be described in detail with reference to the attached drawings.

Prior to the description, the drive motor 300 described below refers to a normal deceleration motor whose drive shaft rotates by supplied fuel or applied power and is equipped with a deceleration function that can reduce the rotation speed, according to the present invention. Detailed explanations will be omitted so as not to obscure the point.

First, as shown in FIGS. 1 to 3, the threshing machine 1 according to the present invention largely includes a base 100, a threshing unit 200, a drive motor 300, and a speed control member 400. .

In more detail, the base 100 is equipped with a drive motor 300, as well as a threshing unit 200 and a speed control member 400, which will be described later, and can be moved and fixed by the user depending on the work position. It refers to a means of transportation and includes a bracket 110, wheels 120, and safety membrane 130.

For example, as shown, the bracket 110 connects a plurality of brackets 110 having lengths in the horizontal and vertical directions to each other using fastening means such as bolts or screws or welding to enable other components to be mounted stably. This is a configuration for

A threshing unit 200 is rotatably mounted on the front of the bracket 110, and a drive motor 300 that provides power to rotate the threshing unit 200 is provided at the top, and a pair of handles at the rear ( 113) is formed to allow the user to move the threshing device 1 by external force after gripping it.

At this time, it is preferable that a latch 111 through which the operating bar 450, which will be described later, can be fastened or released is formed on the outer surface of the bracket 110 that connects the pair of handles 113 to each other.

In addition, the wheels 120 are rotatably installed on the bracket 110 on both sides of the base 100 so that the threshing machine 1 can easily move along the ground G.

In addition, the safety film 130 is installed in the shape of a plate on the upper part of the base 100 and is molded using a transparent synthetic resin material such as acrylic to visually identify whether the threshing machine 1 is operating. The operation of prevents safety accidents by preventing grains from bouncing in the direction of the user, that is, toward the handle 113.

In addition, as shown in FIGS. 1 and 4, the threshing unit 200 is rotatably installed in front of the base 100 described above and directly strikes grains scattered on the ground, causing grains to fall from the grains. It includes a first shaft rod 210, a second shaft rod 220, a belt 230, and a striking member 240.

For example, the first shaft rod 210 is molded into the shape of a cylinder with a predetermined length. One side is connected to the drive motor 300 to receive power for rotation, and the other side is rotatably coupled to the bracket 110.

A circular first pulley 211 is rotatably installed on the outer surface of the first shaft rod 210, and a belt 230 for connecting to the second pulley 221 is installed on the outer surface of the first pulley 211 and driven. It has a structure in which the rotational force of the motor 300 is transmitted to the second shaft rod 220 so that it can rotate together.

For this purpose, as shown, the second shaft rod 220 is rotatably coupled to the bracket 110 on both sides so as to be adjacent to the first shaft rod 210 at a predetermined distance, and the first pulley is attached to the outer surface by a belt 230. A second pulley 221 is formed that is rotatably connected to (211).

At this time, the second pulley 221 is connected to the first pulley 211 and the belt 230 to be located in the center based on the length from the front end to the rear end of the second shaft rod 220, and is connected to the drive motor 300. It is desirable to be able to transmit the rotational force, and through this, it is desirable to enable at least one striking member 240 to be installed at equal intervals and numbers on both sides of the second pulley 221.

Here, the striking member 240 is configured to directly strike the grain so that the grains fall, and includes a fixture 241 and a striking body 245.

As shown, the fixture 241 is detachably coupled by a fastening means to surround the outer surface of the second shaft rod 220, and an insertion hole 243 for inserting the striking body 245 is formed at the top.

The striking body 245 is formed to have an overall curved shape using a flexible material such as rubber, and one side is inserted into the insertion hole 243 and then fastened to the fixture 241 through a fastening means to form the second shaft rod 220. ) strikes the grain through rotation.

At this time, the reason why the hitting body 245 has a curved shape is because when hitting grain in a vertical state, the probability of durability deteriorating due to the impact increases relatively compared to when it has a curved shape, and this effect is further maximized. It is desirable that the grain be struck only with the end of the striking body 245.

In addition, a plurality of striking members 240 provided on the outer surface of the second shaft rod 220 are installed so that each striking body 245 faces a different direction, so that the rotation speed of the second shaft rod 220 is reduced. This disperses the impact from the blow and allows it to hit the grain.

That is, when multiple striking bodies 245 hit grain at once, the force causing the grains to bounce due to the impact becomes relatively large, causing the grains to bounce or be collected to the user beyond the safety barrier 130 described above. Since the inventor's threshing machine (1) can fly relatively far from the installed position, the impact caused by the striking body (245) is dispersed so that the grains fall.

And, as shown in FIGS. 1, 5, and 6, the speed control member 400 can additionally reduce or completely stop the rotational speed of the threshing unit 200 rotated by the drive motor 300. It includes a support piece 410, a first link 420, a second link 440, an operating bar 450, and an elastic body 460. In order to stop the threshing unit 200, Let us explain by example.

For example, as shown, the support piece 410 has a length in the vertical direction and is fixed to the bracket 110 so as to be located behind the first shaft rod 210, and is rotatable on one side of the first link 420 at the top. Combine.

Here, a cylindrical pressing body 430 is installed on the other side of the first link 420, and the pressing body 430 is located on the upper part of the belt 230 extending from the first pulley 211, and has a It is rotatably coupled to one side of the second link 440, and the other side of the second link 440 is rotatably coupled to the outer surface of the operating bar 450 through an elastic body 460.

In addition, as shown, the operating bar 450 is installed so that the lower part can be rotatably coupled to the bracket 110, and when the operating bar 450 is pulled by the user in the direction of the handle 113, the elastic body 460 ), the second link 440 connected to the linear motion is pulled, and at the same time, the first link 420 connected to the second link 440 changes to a rotational motion that rotates with respect to the support piece 410.

Through this, when the first link 420 rotates, the pressing body 430 provided on the first link 420 moves downward and presses the outer surface of the belt 230, thereby stopping the belt 230. Accordingly, the first shaft rod 210 and the second shaft rod 220 are stopped at the same time, so that the driving of the threshing unit 200 is in a stopped state.

Meanwhile, the operating bar 450 in the present invention is pulled in the direction of the handle and is simultaneously bound to the latch 111 described above, so that the operating bar 450 is held in the threshing unit 200 until the operating bar 450 is released from the latch 111. It is possible to maintain a stationary state.

In addition, the elastic body 460 is such that when the operating bar 450 is released from the latch 111, the operating bar 450 automatically moves forward by elastic force and maintains that state so that the threshing unit 200 operates. The elastic body 460 is provided in the form of a coil spring so that it can be connected between the second link 440 and the operating bar 450.

As described above, the threshing machine (1) according to the present invention has a simplified structure that is different from the conventional one, so that it can not only provide economic benefits but also smoothly perform the threshing function, and can be easily performed regardless of the user's skill level. It is usable and has excellent durability.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , those skilled in the art can make various modifications and variations from this description.

Therefore, the spirit of the present invention should not be limited to the described embodiments, and the scope of the patent claims described later as well as all things that are equivalent or equivalent to the scope of this patent claim shall fall within the scope of the spirit of the present invention. .
