Problems solved by technology

[0003] At present, in rice scientific research, a large number (tens of thousands or even hundreds of thousands of ears) of excellent single ears are often selected from the field for scientific experiments in the next year. These single ears of rice need to be threshed separately and cannot be mixed. , while the existing rice threshers are large or medium-sized, mainly for the mixed threshing of large batches of rice, and the effect of small threshing equipment on a single ear of rice is not very good.
Therefore, in the scientific research of rice, the method of threshing is generally carried out by hand, which is time-consuming and labor-intensive, and the work efficiency is extremely low

[0040] Please refer to figure 1 -3. This embodiment provides a rice single ear thresher, which includes a casing 100 and a first threshing mechanism.

[0041] Wherein, the casing 100 includes a casing and a bracket, and the casing is welded to the top of the bracket. Both the shell and the bracket are made of carbon steel to ensure that it has sufficient mechanical strength, and at the same time, the outer surface is painted with a paint layer to delay rust and corrosion and prolong the service life.

[0042] The casing 100 is provided with a rice inlet 110 , a grain outlet 120 and a waste outlet 130 for discharging branches, cobs and stalks, wherein the rice inlet 110 and the waste outlet 130 are located on the grain outlet 120 . Both the rice inlet 110 and the grain outlet 120 are provided with a guide plate, which is used to guide the rice into the casing 100 from the rice inlet 110 and guide the threshed stalks out of the casing 100 from the waste outlet 130 .

[0057] Please refer to Figure 4 , this embodiment provides a rice single-ear thresher, its composition structure, working principle and technical effect obtained are basically the same as those of the first embodiment, the difference is that the rice single-ear thresher provided by this embodiment is in the first On the basis of the embodiment, a cutting device is added.

[0058] The above-mentioned cutting device is disposed at a position corresponding to the waste outlet 130 on the casing 100 . Specifically, the cutting device includes a fixed knife 600 , a moving knife 610 and a cutting motor for driving the moving knife 610 to rotate. Wherein, both the fixed knife 600 and the movable knife 610 are elongated, the fixed knife 600 is fixedly installed on the top of the waste outlet 130 , and its cutting edge is positioned downward, and the stem flows out from the bottom of the fixed knife 600 . The moving knife 610 is rotatably connected to a rotating rod 620 and is perpen...

[0062] Please refer to Figure 5 -7. This embodiment provides a rice single-ear thresher. Its composition, working principle and technical effects are basically the same as those of the first embodiment or the second embodiment. The difference is that the rice The single ear thresher has added a second threshing mechanism on the basis of the first embodiment or the second embodiment.

[0063] The above-mentioned second threshing mechanism is used for secondary threshing of the rice passing through the threshing gap. Specifically, the second threshing mechanism includes a third drum 700 rotatably connected in the housing 100 and a second motor for driving the third drum 700 to rotate.

[0064] Wherein, the third roller 700 is in the shape of a round tube and is inclined. The specific angle of inclination is determined according to actual needs, generally 15°-30°. The side wall of the third cylinder 700 is provided with a plurality of grain filter holes 710, a plurality of gra...

Abstract

The invention relates to a rice single ear threshing machine, and belongs to the field of agricultural machines. The rice single ear threshing machine comprises a machine casing and a first threshing mechanism, wherein the machine casing is provided with a rice inlet, a grain outlet and a waste outlet; the first threshing mechanism comprises a first drum, a second drum and a first engine, and the first engine is used for driving the first drum and the second drum to rotate; first brush strips are respectively arranged on the first drum and the second drum, and are used for removing grains from stems; a threshing gap is formed between the first drum and the second drum, the rice can pass through the threshing gap, and the threshing gap corresponds to the rice inlet; the grain outlet is positioned at the bottom part of the machine casing, and the waste outlet is positioned at one side, away from the rice outlet, of the first threshing mechanism. The rice single ear threshing machine has the advantages that the two drums with the brush strips are arranged at interval to form the threshing gap structure, and the rice can be threshed through the threshing gap; the threshing effect is good, and the grains, stems, ear stalks and stem stalks of the rice can be effectively separated; the purpose of single ear threshing is realized, and the mutual mixing is avoided.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a rice single ear thresher. Background technique [0002] Threshing is one of the most important steps in the crop harvesting process. The harvested rice grains are removed from the rice ears, and other protruding objects such as branches, cobs, stems and grains are separated as much as possible. come out. [0003] At present, in rice scientific research, a large number (tens of thousands or even hundreds of thousands of ears) of excellent single ears are often selected from the field for scientific experiments in the next year. These single ears of rice need to be threshed separately and cannot be mixed. , while the existing rice threshers are large or medium-sized, mainly aimed at the mixed threshing of rice in large quantities, and the small-sized threshing equipment is not very good for the threshing effect of a single ear of rice. Therefore, in the scientific research...
