Description

A kind of corn thresher

technical field

The invention relates to the field of agricultural machinery, in particular to a corn thresher.

Background technique

Corn is a kind of delicacy with a sweet taste. It is not uncommon on the table and is deeply loved by everyone. Corn kernels are also an important raw material for making delicious dishes. Corn threshing is an essential process for making corn kernels.

The traditional processing method is to use manual threshing of corn. With the development of science and technology, people have designed an automatic corn thresher. The threshing of corn through the corn thresher has the advantages of simplicity, speed, and high efficiency.

There are no design standards or specifications for corn threshers in the prior art, and most corn threshers are designed and sold by manufacturers themselves, so their principles and structures are quite different, and the structure design of most corn threshers is not reasonable enough. It is more troublesome, the threshing effect is poor, and the efficiency is low.

The Chinese invention patent with the patent application number CN201510542511.0 discloses a corn thresher. This corn thresher is provided with a weighing gate at the connection between the feed hopper and the shell of the thresher, and a weighing control is provided on the weighing gate. The threshing device includes two parallel threshing rollers and a threshing screen arranged under the threshing rollers; the threshing roller is cylindrical, with a rotating shaft connected in the middle, and the rotating shaft is connected to the output motor. Triangular nail teeth; the screening device includes a vibrating screen arranged under the threshing screen, the vibrating screen includes a first-level vibrating screen with 8-20 meshes in the upper layer, a second-level vibrating screen with 40-55 meshes in the lower layer, and a secondary vibrating screen with 40-55 meshes in the lower layer. There is a debris compartment under the vibrating screen.

The structure of this corn thresher is slightly simple, and the threshing effect is poor.

The Chinese invention patent with the patent application number CN201510528055.4 discloses a corn threshing machine, which includes a threshing device installed in the threshing bin. The threshing device is equipped with a threshing roller and a support roller driven by power. The threshing ribs, the threshing roller and the support roller rotate in the same direction and have a set distance; the front and rear ends of the threshing bin are respectively provided with a feed hopper and a core outlet, and the rear of the threshing bin is provided with a discharge port; the support roller is located at the threshing roller Below one side and above the other side of the support roller is an auxiliary support roller without power input. The auxiliary support roller is rotatably arranged on the frame of the threshing machine, and is fixedly connected with the frame through a detachable connection structure. A V-shaped threshing space is formed between the support roller, the support roller and the threshing roller, and the distance between the auxiliary support roller and the threshing roller gradually decreases along the corncob threshing moving direction.

Although the corn thresher structure of this structure looks quite complicated, the actual effect is general.

Therefore it can be seen that the structure design of the corn thresher in the prior art is not reasonable enough, can not really play the effect of fast threshing, has limited the development of agricultural science and technology, makes the farmer spend bigger price and still can't buy satisfactory product.

The transmission device 103 is an intermediate structure, used to drive the threshing device 104 to run. The threshing device 104 is the main operating part of the threshing work; the feeding device 105 is used for feeding into the machine body 101 .

The driving device 102 is connected with the threshing device 104 through the transmission device 103, and a threshing channel is provided in the body 101, and the feeding device 105 communicates with the threshing channel, and the threshing device 104 is arranged outside the body 101; after the corn is put into the threshing device 104, it enters the threshing channel The threshing work is completed in the threshing channel, and the threshing device 104 arranged outside the body 101 is convenient for putting corn into the body 101 .

The transmission device 103 is used to transmit power, and whether the structural design of the transmission device 103 is reasonable is related to whether the threshing device 104 can run smoothly, so it is more important. In this embodiment, the transmission device 103 includes a first transmission assembly 201, a second transmission assembly 202, and a third transmission assembly 203. The mutual cooperation of multiple sets of transmission assemblies makes the power transmission work smoothly; specifically, the first transmission assembly 201 includes a coaxial first transmission shaft 301 and a first transmission gear 401, the second transmission assembly 202 includes a coaxial second transmission shaft 302, a second transmission gear 402 and a third transmission gear 403, the third transmission assembly 203 includes a third transmission shaft 303 and a fourth transmission gear 404 coaxially arranged; the driving device 102 includes a driving gear 407 meshing with the first transmission gear 401, and the first transmission gear 401 is meshed with the second transmission gear 402 The second transmission shaft 302 and the third transmission shaft 303 are arranged symmetrically below the threshing channel, and the third transmission gear 403 , the fourth transmission gear 404 and the threshing device 104 are driven by the first transmission chain 305 .

As shown in Figure 7, when the transmission device 103 of this structure is working, the driving device 102 outputs power, which is transmitted to the first transmission gear 401 through the driving gear 407, and the first transmission gear 401 is transmitted to the second transmission gear 402, and the power is transmitted to the second transmission gear 402 through the first transmission gear 407. The second transmission shaft 302 is transmitted to the third transmission gear 403, and the third transmission gear 403, the fourth transmission gear 404 and the threshing device 104 are connected through the first transmission chain 305, so that all components can run synchronously.

Therefore, it can be seen that the corn thresher with this structure can smoothly and stably thresh corn, has high power transmission efficiency, high threshing efficiency, stable quality, reasonable cost, and is easy to popularize.

Specifically, the ends of the first transmission shaft 301 , the second transmission shaft 302 and the third transmission shaft 303 are all connected in rotation with the body 101 , and the first transmission gear 401 is detachably connected with the first transmission shaft 301 . The rotational connection relationship between the transmission shaft and the body 101 enables each transmission shaft to rotate relative to the body 101 during work; each transmission gear is detachably connected to each transmission shaft, so that each part is convenient for processing and assembling, and the gears rotate when the transmission shaft rotates . In this embodiment, the transmission gear is keyed to the transmission shaft.

The threshing device 104 is used for threshing, and corn threshers in the prior art also include this device. In this embodiment, the threshing device 104 includes a threshing cylinder 501, and the outside of the threshing cylinder 501 is provided with an annular drive tooth 502. The inside of the threshing cylinder 501 is provided with a threshing gear 503 group. The transmission gear 502 is connected with the first transmission chain 305 for power transmission; the threshing gear 503 group is arranged inside the threshing cylinder 501 for threshing.

There are many ways to set up the threshing teeth 503 groups. In the present embodiment, the threshing teeth 503 groups have multiple groups distributed in a circle, and each group of threshing teeth 503 groups includes multiple rows of threshing teeth 503, and each row of threshing teeth 503 It is arranged obliquely relative to the axis of the threshing channel. As shown in the figure, during the rotation of the threshing device 104, multiple threshing teeth 503 collide with and squeeze the corn, and the huge force generated can separate the corn kernels from the corn cob. It can be seen from Fig. 10 that each row of threshing teeth 503 is inclined to the axis of the threshing passage, so that each row of threshing teeth 503 can exert a forward force on the corn cob during the rotation of the threshing cylinder 501, so that the corn cob is in the process of turning. It can move forward during the threshing process, so that this part does not need to be additionally provided with a separate propulsion device to push the corn forward, so that the corn threshing work can run smoothly.

The threshing cylinder 501 needs to rotate during operation. As shown in the figure, a plurality of annularly distributed balls can be arranged outside it, so that the threshing cylinder 501 is connected with the inner wall of the body 101 through the balls, which not only supports the threshing cylinder 501, but also And the relationship between the threshing cylinder 501 and the machine body 101 is a rolling relationship, the friction force is small, the energy loss is small, and the threshing effect is better.

In order to assist the threshing work of the threshing cylinder 501 , at least one threshing ring 504 is provided outside the threshing channel. The threshing ring 504 is provided with a toothed structure, and the threshing ring 504 is connected with the transmission device 103 . The toothed structure is used for threshing when the threshing circle 504 rotates.

The threshing circle 504 is connected with the transmission device 103 , which may be like this: the threshing circle 504 is connected with the third transmission gear 403 and the fourth transmission gear 404 through the second transmission chain 306 .

The transmission gear 406 and the threshing ring 504 are connected with the third transmission gear 403 and the sixth transmission gear 406 through the second transmission chain 306 . As shown in FIG. 7 , the operation of the fifth transmission gear 405 and the sixth transmission gear 406 drives the threshing ring 504 to rotate. There can be more than one threshing circle 504, there can be two or more, and the positions of the two threshing circles 504 are shown in Figure 7, and the two threshing circles 504 are respectively driven by different transmission gears, and the two threshing circles The outer diameters of 504 are inconsistent, so that the rotation speeds are inconsistent when working. Through the operation of the threshing ring 504 at different speeds, the corn cobs are subjected to different torsion forces at the front and rear, so that the threshing is more thorough and the effect is better.

In order to facilitate the feeding of corn cobs, the end of the feeding device 105 away from the body 101 is provided with a feeding port 505. The feeding port 505 is funnel-shaped, and the funnel-shaped feeding port 505 is convenient for feeding; The stick slides down easily for smoother operation.

When each transmission chain is in operation, there may be slack or excessive tension. In order to adjust the tension of the transmission chain, the end of the second transmission shaft 302 or the third transmission shaft 303 is connected to the body 101 through the adjustment mechanism 106; the adjustment mechanism 106 includes an adjustment block 601, an adjustment bolt 602 and an adjustment spring 603. The body 101 is provided with a bar-shaped chute 604, the adjustment block 601 is located in the chute 604, and the second transmission shaft 302 or the third transmission shaft 303 is connected with the adjustment The block 601 is rotatably connected, the adjusting bolt 602 and the adjusting spring 603 are respectively arranged on both sides of the adjusting block 601 , and the adjusting bolt 602 is screwed to the body 101 .

As shown in Figure 11, the adjustment bolt 602 is turned to drive the adjustment block 601 to move, and the adjustment spring 603 is arranged on the other side of the adjustment block 601. The adjustment spring 603 always has elastic force on the adjustment block 601, so that the position of the adjustment block 601 is convenient to adjust In addition, if the drive chain is already relatively tight, if you continue to screw the adjusting bolt 602, there may be a possibility that the drive chain will be too tight, and the setting of the adjustment spring 603 can play the role of elastic buffer, so that the drive chain in this case There will be no failure caused by over-tightening.

After the corn kernels are taken off, they need to be collected. The body 101 is also provided with a blanking channel 107, which communicates with the threshing channel. The corncob falls from the end of the threshing passage, and the corn kernels fall from the end of the feeding passage 107 .
