[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Example 1:

[0022] Reference Figure 1-4 A rice threshing device includes a bottom support 1 and a rice threshing chamber 4. A drive motor 2 is installed above the bottom support 1 and is fixedly installed on the outside of the rice threshing chamber 4. The rice threshing chamber 4 is divided into an upper screening chamber 5 and a lower screening chamber 6. A feeding plate 3 is installed above the rice threshing chamber 4 for feeding rice.

[0023] The outer side of the feeding sleeve 3 is equipped with a chute. The operator pours the rice to be threshed into the rice threshing chamber 4 through the feeding sleeve 3 for threshing. At the same time, the threshing chamber 4 is stratified. According to the specific rice threshing task requirements, rice of different processing standards can be taken out from the outer side of the upper screening chamber 5 and the lower screening chamber 6, thereby effectively improving the adaptability of the device and making it easy to adapt to processing tasks under different conditions.

[0024] The rice threshing chamber 4 includes a feeding plate 101, a heating layer 102, a large particle removal component 103, a spiral filter chamber 104, a stirring shaft 105, stirring blades 106, a waste screening slot 107, and a discharge pipe 108. The feeding plate 101 is configured to cooperate with the feeding sleeve plate 3. The heating layer 102 is configured to cooperate with the outer side of the feeding plate 101. The large particle removal component 103 is configured to cooperate with the inner side of the heating layer 102. The spiral filter chamber 104 is configured to cooperate with the large particle removal component 103. The stirring shaft 105 is configured to cooperate with the spiral filter chamber 104. The stirring blades 106 are coaxially configured on the stirring shaft 105. The waste screening slot 107 is configured to cooperate with the stirring shaft 105. The discharge pipe 108 is configured to cooperate with the waste screening slot 107 and is installed at the bottom of the rice threshing chamber 4. The rice threshing bin 4 is capable of sorting rice and removing impurities. The specific working steps are as follows:

[0025] After the rice grains are threshed, they enter the rice threshing chamber 4 and first fall through the feed plate 101 into the heating layer 102. The heating layer 102 is equipped with heating resistors, which provide heating during the threshing process in the threshing chamber 4, thereby drying some of the rice grains that contain moisture, facilitating subsequent secondary processing. At the same time, the rice grains are initially sorted by the large particle removal component 103 in the upper screening chamber 5. The sorted rice grains fall into the lower screening chamber 6, where they are agitated and vibrated by the stirring blades inside, allowing for secondary processing of the rice grains that were not completely threshed, thus improving the overall work efficiency. The rice grains that have undergone secondary processing are then sorted a third time through the waste removal chute 107 at the bottom. After sorting, they are transported through the discharge pipe 108 at the bottom.

[0026] The large particle removal component 103 includes a screening shaft 201, rotating shaving teeth 202, and a particle filter chamber 203. The screening shaft 201 is fitted inside the rice threshing chamber 4, and the particle filter chamber 203 is coaxially mounted on the screening shaft 201. Multiple sets of evenly distributed rotating shaving teeth 202 are fitted onto the outer wall of the particle filter chamber 203. During rotation, the rotating shaving teeth 202 match the specifications inside the upper screening chamber 5, preventing the rice to be threshed from leaking downwards through the gap between the rotating shaving teeth 202 and the upper screening chamber 5. Simultaneously, a particle filter membrane is provided on the outer wall of the particle filter chamber 203.

[0027] The particle filter chamber 203 has a hollow structure inside, and a particle filter membrane is provided on the surface of the particle filter chamber 203. The particle filter membrane can filter and screen impurities such as sand and gravel in the rice, thereby improving the overall processing quality of the rice.

[0028] An upper output shaft 301 and a lower output shaft 302 are fitted onto the outer side wall of the rice threshing chamber 4. The upper output shaft 301 is coaxially fitted with the screening shaft 201, and the lower output shaft 302 is coaxially fitted with the stirring shaft 105. Both the upper output shaft 301 and the lower output shaft 302 are connected to the output end of the drive motor 2 via a belt. This device uses the drive motor 2 for functional processing. The upper output shaft 301 and the lower output shaft 302, connected by a belt, can work together under the drive of the drive motor 2, thereby improving the threshing efficiency of the rice and reducing the subsequent production costs of the device.

[0029] The waste screening slot 107 is equipped with multiple independent rice grain screening units 401 spaced at equal intervals. Each independent rice grain screening unit 401 has a limiting buckle 402 and a hollow trough 403 inside. The limiting buckle 402 is positioned on the outside of the hollow trough 403. The waste screening slot 107 can change the size of the hollow trough 403 according to actual needs, so that rice grains of the specified size can be sorted into the discharge pipe 108 below. The independent rice grain screening unit 401 is a replaceable component; the limiting buckle 402 and hollow trough 403 can be replaced according to actual rice grain processing requirements, thus adapting to rice threshing operations of different specifications.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
