Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural equipment technology, and in particular relates to a rice threshing device with slag discharge function. Background Technology
[0002] Harvesting and processing rice are crucial steps. Traditional rice threshing methods mainly rely on manual threshing or simple threshing tools. These methods are extremely inefficient and cannot meet the needs of large-scale agricultural production. With the development of agricultural mechanization, rice threshing devices have emerged and gradually become widespread.
[0003] However, existing rice threshing devices with slag removal functions contain a large amount of impurities such as rice husks, straw, and dust in the threshed rice. During rice storage, these impurities absorb moisture, increasing the humidity around the rice. When the humidity reaches a certain level, the rice is prone to mold and sprouting, reducing the quality and shelf life of the rice. Utility Model Content
[0004] The purpose of this utility model is to provide a rice threshing device with a slag removal function. By setting up a slag removal mechanism, the problem of existing rice threshing devices with slag removal function having a large amount of rice husks, straw fragments, dust and other impurities mixed in with the threshed rice during use is solved. During the storage of rice, these impurities will absorb moisture, increasing the humidity around the rice. When the humidity reaches a certain level, the rice is prone to mold and sprouting, which reduces the quality and shelf life of the rice.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a rice threshing device with a slag discharge function, including a lower shell, on which a slag discharge mechanism and a threshing mechanism are provided;
[0007] The upper shell is hinged to the top of the lower shell. Several grooves are opened at the bottom of the lower shell, and all grooves penetrate the lower shell. The slag discharge mechanism includes a blowing assembly and a limiting assembly. The blowing assembly includes two rings fixedly connected to the inner wall of the lower shell. The two rings are located on the left and right sides of the lower shell, respectively. A cross support frame is fixedly connected to the inner wall of the ring on the right side. A rotating shaft passes through the central axis of the cross support frame. A motor is fixedly connected to the right side of the cross support frame. The output shaft of the motor is fixedly connected to the rotating shaft via a coupling.
[0008] Furthermore, a disc is fixedly connected to the left extension of the rotating shaft, and several fan blades are fixedly connected to the outer wall of the disc.
[0009] Furthermore, the limiting component includes a rotating groove formed on the cross support frame, and a retaining ring is fixedly connected to the outer wall of the rotating shaft, the outer wall of the retaining ring extending rotatably into the rotating groove.
[0010] Furthermore, the threshing mechanism includes a support frame fixedly connected to the inner wall of the left circular ring, and a rotating shaft 2 rotatably passes through the central axis of the support frame.
[0011] Furthermore, a second motor is fixedly connected to the left side of the support frame, and the output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling. A threshing roller is fixedly connected to the outer wall of the second rotating shaft, and several threshing teeth are fixedly connected to the outer wall of the threshing roller.
[0012] Furthermore, a feed inlet is provided on the outer wall of the upper housing, and two bases are fixedly connected to the bottom of the lower housing.
[0013] Furthermore, an L-shaped plate is fixedly connected to each of the two bases on their adjacent sides, and a collection box is slidably connected between the two L-shaped plates.
[0014] This utility model has the following beneficial effects:
[0015] 1. By setting up a threshing mechanism, when rice needs to be threshed, the rice to be threshed can be put into the lower and upper shells through the feed inlet. Then, motor two is started, which drives shaft two to rotate, which in turn drives the threshing roller to rotate, thereby driving the threshing teeth to thresh the rice in the lower and upper shells. The threshed rice grains will fall into the collection box through the chute. Moreover, the rotation of the threshing teeth will disperse the distribution of rice in the device. The rice grains stuck in the rice straw after threshing will also fall into the collection box under this rotation, so that the rice can contact the threshing teeth more evenly, avoiding the situation where rice piles up and some rice cannot be fully threshed. This improves the integrity and efficiency of threshing, and can process a large amount of rice in a short time to meet the needs of large-scale rice threshing.
[0016] 2. By setting up a slag discharge mechanism, motor one is started at the same time as motor two. Motor one will drive the rotating shaft one to rotate stably on the cross support frame under the action of the rotating groove and the retaining ring. When the rotating shaft one rotates, it will drive the disc and the fan blades on the disc to rotate, thereby generating wind power to blow the rice in the device and blow the threshed rice straw out of the device. This allows the lighter rice straw to be blown away from the device quickly and effectively, while the heavier rice grains will fall into the collection box, realizing the separation of the two and effectively avoiding the situation where the threshed straw occupies space in the device, resulting in low processing efficiency.
[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5As shown, this utility model is a rice threshing device with a slag removal function, including a lower shell 1, a slag removal mechanism 2 and a threshing mechanism 3 on the lower shell 1, an upper shell 101 hinged to the top of the lower shell 1, and several troughs 102 opened at the bottom of the lower shell 1, all of which penetrate the lower shell 1. The slag removal mechanism 2 includes a blowing assembly 21 and a limiting assembly 22. The blowing assembly 21 includes two rings 211 fixedly connected to the inner wall of the lower shell 1, the two rings 211 being located on the left and right sides of the lower shell 1 respectively. A cross support frame 212 is fixedly connected to the inner wall of the ring 211 on the right side, and a rotating shaft 213 rotatably passes through the central axis of the cross support frame 212. A motor 214 is fixedly connected to the side. The output shaft of the motor 214 is fixedly connected to the rotating shaft 213 via a coupling. A disc 215 is fixedly connected to the left extension of the rotating shaft 213. Several fan blades 216 are fixedly connected to the outer wall of the disc 215. The limiting component 22 includes a rotating groove 221 opened on the cross support frame 212. A retaining ring 222 is fixedly connected to the outer wall of the rotating shaft 213. The outer wall of the retaining ring 222 extends rotatably into the rotating groove 221. By setting the slag discharge mechanism 2, the lighter rice straw can be blown away from the device quickly and effectively, while the heavier rice grains will fall into the collection box 106, realizing the separation of the two and effectively avoiding the situation where the straw after threshing occupies space in the device, resulting in low processing efficiency.
[0028] The threshing mechanism 3 includes a support frame 301 fixedly connected to the inner wall of the left circular ring 211. A rotating shaft 302 rotatably passes through the central axis of the support frame 301. A motor 303 is fixedly connected to the left side of the support frame 301. The output shaft of the motor 303 is fixedly connected to the rotating shaft 302 via a coupling. A threshing roller 304 is fixedly connected to the outer wall of the rotating shaft 302. Several threshing teeth 305 are fixedly connected to the outer wall of the threshing roller 304. A feed inlet 10 is provided on the outer wall of the upper housing 101. 3. Two bases 104 are fixedly connected to the bottom of the lower shell 1. L-shaped plates 105 are fixedly connected to the sides of the two bases 104 that are close to each other. A collection box 106 is slidably connected between the two L-shaped plates 105. By setting the threshing mechanism 3, the rice can be made to contact the threshing teeth more evenly, avoiding the situation where the rice piles up and some rice cannot be fully threshed. This improves the integrity and efficiency of threshing, and can process a large amount of rice in a short time to meet the needs of large-scale rice threshing.
[0029] A specific application of this embodiment is as follows: In use, the device is first placed in the appropriate position. When threshing rice is required, the rice to be threshed can be placed into the lower shell 1 and upper shell 101 through the feed inlet 103. Then, the second motor 303 is started, which drives the second rotating shaft 302 to rotate. The second rotating shaft 302, in turn, drives the threshing roller 304 to rotate, thereby causing the threshing teeth 305 to thresh the rice in the lower shell 1 and upper shell 101. The threshed rice grains fall into the collection box 106 through the trough 102. Furthermore, the rotation of the threshing teeth 305 breaks up the rice grains... The rice grains sandwiched in the rice straw after threshing are distributed within the device and fall into the collection box 106 as it rotates. At the same time as starting motor 303, motor 214 is also started. Motor 214, under the action of rotating groove 221 and retaining ring 222, drives rotating shaft 213 to rotate stably on cross support frame 212. When rotating shaft 213 rotates, it drives disc 215 and fan blades 216 on disc 215 to rotate, thereby generating wind to blow the rice inside the device and blow the threshed rice straw outside the device. After threshing, the rice grains in collection box 106 can be collected.
