By installing the placing frame 8, the push plate 11, the ball handle 12 and the reinforcing rod 13 on the outside of the outer cylinder 3, not only threshing is more convenient, but also the efficiency is improved, and the replacement of the corn cob during use is also relatively simple, a gasket 20 is provided on the inner side of the push plate 11, and due to the provision of the gasket 20, the push plate 11 can be prevented from causing wear to the corn grains on the outside of the rice grain cob.

[0029] The outer side of the support frame 1 is fixedly connected to the frame body 14, and the interior of the frame body 14 is provided with a collecting frame 15. The interior of the collecting frame 15 is fixedly connected to a limiting plate 16. There are four groups of limiting plates 16. A filter screen plate 17 is provided on the top of the limiting plate 16. By installing the frame body 14, the collecting frame 15, the limiting plate 16 and the filter screen plate 17 on the outside of the support frame 1, manual secondary recovery of corn cobs and corn kernels can be avoided, and corn cobs and corn kernels can be better recovered during application.

[0030] A slide groove 9 is provided on the inner side of the placement rack 8, a slider 10 is fixedly connected to the bottom of the push plate 11, and the slider 10 is embedded inside the slide groove 9. Due to the slide groove 9 and the slider 10, it is convenient to push the push plate 11 on the top of the placement rack 8.

[0031] The outside of the collecting frame 15 is fixedly connected to a grip rod, a notch 18 is provided on the outside of the frame body 14, a grip 19 is provided inside the notch 18, and the grip 19 is symmetrically distributed. Due to the notch 18, it is convenient to install the grip rod at the notch 18.

[0032] The outside of the drum 4 is fixedly connected to a threshing plate 21 which is distributed in an annular form. The side of the drum 4 is fixedly connected to a connecting block 6 which has a rotating handle 7 on its outside. The connecting block 6 facilitates the connection of the rotating handle 7 to the bearing 5.

[0033] The outer part of the outer cylinder 3 is fixedly connected to the support rod 2 , and a support frame 1 is provided at the bottom of the support rod 2 . The support rod 2 facilitates the fixed connection between the outer cylinder 3 and the support frame 1 .

[0034] The working principle of the corn threshing device: when using the threshing device, it is first necessary to move it to the designated position, and the user holds the support frame 1 to move it. When it is moved to the designated position, the support frame 1 is placed on the ground. However, in order to facilitate the recovery of corn kernels and corn cobs, a structure for convenient recovery is installed on the outside. By installing the frame body 14, the collection frame 15, the limiting plate 16, the filter screen plate 17, the handle 19 and other structures on the outside of the support frame 1, first hold the handle 19 to install the collection frame 15 inside the frame body 14, and at the same time fix the limiting plate 16 inside the collection frame 15, and then place the filter screen plate 17 on the top of the limiting plate 16. After the corn is threshed, the corn cobs will fall on the top of the filter screen plate 17, and then the corn kernels will directly fall into the collection frame 15 through the filter screen plate 17. This avoids manual secondary recovery of corn cobs and corn kernels, and can better recover corn cobs and corn kernels when used. After the corn kernels are filled, the corn cob on the top of the filter screen plate 17 is taken out, and then the corn in the collecting frame 15 is transferred to the designated position for threshing. Secondly, in order to improve the efficiency of putting corn cobs, a placement rack 8, a push plate 11, a ball handle 12, a reinforcement rod 13 and other structures are installed on the outside of the outer cylinder 3. When the corn needs to be threshed, the ball handle 12 on the back of the push plate 11 is pulled in the opposite direction to drive the slider 10 to move in the slide groove 9 inside the placement rack 8, and then the corn cob is placed inside the placement rack 8. The staff member twists the rotating handle 7 with one hand and pushes the corn cob inside the push plate 11 with the other hand to thresh. In this way, threshing is not only more convenient, but also more efficient. It is also relatively simple to replace the corn cobs during use. After all the corn cobs in the placement rack 8 are threshed, other corn cobs can be placed for threshing. In addition, a gasket 20 is installed inside the push plate 11 to avoid squeezing between the push plate 11 and the corn cobs, thereby affecting the corn kernels.
