Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a thresher for corn threshing. Background Technology

[0002] Crops are the product of agriculture, which is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. After harvesting, crops need to be further processed using equipment. Corn, as a common crop, requires threshing after harvesting. During threshing, whole corn kernels are often mixed with broken kernels, affecting product quality and hindering the maximization of economic benefits. Utility Model Content

[0003] The purpose of this utility model is to provide a corn thresher that integrates threshing, screening, and collection of whole corn kernels and broken kernels by setting up a screening component.

[0004] To achieve the purpose of this utility model, a threshing machine for corn threshing is provided, comprising: a frame, a threshing chamber inside the frame, a threshing assembly installed in the threshing chamber, a feed inlet at the top of the frame communicating with the threshing chamber, a grain outlet at the bottom of the threshing chamber, a collection chamber below the grain outlet, a screening assembly installed in the collection chamber, the screening assembly including a screen, the screen being inclinedly disposed within the collection chamber, a grain breaking channel at the bottom of the screen, a grain sizing channel at the lower side of the screen, a recycling box slot near the bottom of the front of the frame communicating with the collection chamber, a grain breaking box and a grain sizing box slidably mounted within the recycling box slot, the outlet of the grain breaking channel facing the grain breaking box, and the outlet of the grain sizing channel facing the grain sizing box.

[0005] As a preferred technical solution of this utility model, a core discharge port is provided on the side end of the frame, a core material baffle is provided below the threshing assembly, the core material baffle is fixedly connected to the inner wall of the threshing chamber, and the core discharge port is set directly opposite the core material baffle.

[0006] As a preferred embodiment of this utility model, the inner wall of the feed inlet is provided with a guide plate, and the guide plate is inclined.

[0007] As a preferred embodiment of this invention, the surface of the guide plate is covered with an anti-stick coating.

[0008] As a preferred embodiment of this utility model, the sieve hole diameter on the sieve surface is 3-5mm.

[0009] As a preferred technical solution of this utility model, a guide plate is provided on the upper surface of the screen, and the guide plate is flared and gradually narrows from both ends of the screen to the particle-forming channel.

[0010] As a preferred embodiment of this invention, a vibration motor is installed on the side end of the screen.

[0011] Compared with the prior art, this utility model provides a thresher for corn threshing, which has the following beneficial effects:

[0012] In use, corn is fed into the inlet and guided evenly into the threshing chamber by the guide plate. The threshing assembly performs the threshing process. The structure and working principle of the threshing assembly are existing mature technologies. After threshing, the corn cob and corn kernels are separated by the cob material barrier. The corn cob remains on the cob material barrier and is discharged through the cob discharge port, while the corn kernels fall onto the screen through the kernel outlet. Due to the inclined screen setting, coupled with the vibration motor driving the screen to shake, and the fact that the screen is connected to the inner wall of the collection chamber by springs at both ends during installation, the shaking amplitude of the screen is further enhanced. Whole kernels with a diameter >5mm fall into the kernel box through the kernel channel; broken kernels with a diameter <3mm pass through the screen holes and fall into the broken kernel box through the broken kernel channel, realizing the integration of threshing, screening and collection of whole corn kernels and broken kernels.
