Description

Technical Field

[0001] The utility model relates to the technical field of threshers, in particular to a thresher for preventing grain splashing. Background Art

[0002] A thresher is an important agricultural machine, mainly used for threshing, that is, separating the grains and stems in crops. By manually placing the rice ears on a high-speed rotating drum and sieve, when the grains enter the drum, the rotation of the drum will cause the grains to be squeezed and rubbed, so as to thresh the grains from the ears. However, when the rice ears are stressed, the grains will splash.

[0003] According to the "thresher for preventing grain splashing" with the Chinese patent publication number CN220755615U, it mainly describes that through the use of a protective cover, a limiting component and a threshing and slag discharging component, during the threshing process of the device, after putting the rice into the feeding port, it can automatically thresh, and at the same time, it can discharge the rice straws and weeds from the machine body. During the threshing process, it can effectively prevent the sputtering of grains, and there is no need for the user to collect the splashed rice, reducing the burden on the user. During this process, some rice ear stalks are prone to get stuck inside the box body after being broken, resulting in poor quality of the threshed grains.

[0004] Therefore, a thresher for preventing grain splashing is proposed to solve the problem that during this process, some rice ear stalks are prone to get stuck inside the box body after being broken, resulting in poor quality of the threshed grains. Content of the Utility Model

Detailed implementation mode

[0016] The present utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figures 1 - 3 A threshing machine for preventing grain splashing as shown in the figure, including a threshing box 1, a feeding port 2 is opened on one side of the threshing box 1, a driving motor is fixedly connected to one side of the threshing box 1, and an output end of the driving motor is fixedly connected to a threshing roller 3. The threshing roller 3 is matched with hook-shaped protrusions 4, and the rice ears on the rice panicles can be threshed by high-speed rotation. Hook-shaped protrusions 4 are evenly fixedly connected to the threshing roller 3. A first groove 5 is opened at the upper end of the threshing box 1. A support is fixedly connected to the threshing box 1 inside the first groove 5. A first fan 6 is rotatably connected to the support. When the first fan 6 rotates, it can intake air from the first groove 5 and promote the rice grains and debris to fall into the gap between the buffer block 7 and the threshing roller 3. At the same time, the buffer block 7 can provide buffering when colliding with the rice grains. A buffer block 7 is fixedly connected to the threshing box 1 on one side of the first groove 5. The buffer block 7 is made of rubber material. An outlet groove 8 is opened on one side inside the threshing box 1. A receiving plate 9 is fixedly connected to the threshing box 1 at the bottom side of the outlet groove 8. The receiving plate 9 can guide the debris generated by threshing. A plurality of stop bars 19 are evenly fixedly connected to one side of the upper end of the receiving plate 9. The stop bars 19 can block the broken straws. A support plate 10 is fixedly connected to the threshing box 1 above the outlet groove 8. A second fan 11 is rotatably connected to the support plate 10. By setting the speed of the driving motor on one side of the support plate 10, the weight of the rice grains and the weight of the debris can be separated. A groove is opened at the bottom side of the threshing box 1, and a storage frame 12 is inserted into the groove. A pull plate 13 is fixedly connected to one side of the storage frame 12. The pull plate 13 and the storage frame 12 can receive the debris for convenient centralized treatment.

[0018] Wherein, the combing groove is located on the baffle 14, and the combing groove is close to one side of the threshing roller 3. The baffle 14 is fixedly connected to one side of the threshing box 1 where the feeding port 2 is located. By setting the baffle 14 and the combing groove, it can block the debris and dust without blocking the rotation of the threshing roller 3.

[0019] Wherein, an infrared sensor 15 is arranged above the feeding port 2. The infrared sensor 15 is fixedly connected inside the threshing box 1. By setting the infrared sensor 15, it can monitor the material falling into the threshing box 1, so as to perform subsequent operations.

[0020] Wherein, the infrared sensor 15 is connected to an electric push rod 16 through a wire. The width of the hook-shaped protrusion 4 corresponds to the card slot. The card slot is located at the bottom side of the pressing strip 17. The pressing strip 17 is fixedly connected to the output end of the electric push rod 16. The electric push rod 16 is fixedly connected to the bottom side of the connecting strip. The connecting strip is fixedly connected to one side of the threshing box 1. By the extension of the electric push rod 16, the pressing strip 17 is close to the threshing roller 3, so as to squeeze the rice panicles and promote the separation of the rice grains.

[0021] Among them, the connecting strip corresponds to the baffle 18, and the baffle 18 is fixedly connected to the upper end of the pressing strip 17. By providing the baffle 18, when the pressing strip 17 and the threshing roller 3 squeeze the rice ears, it can provide a block to the separated grains.

[0022] Working principle: Manually put the rice ears into the feeding port 2 on one side of the threshing box 1. At this time, the infrared sensor 15 monitors the change in distance and causes the electric push rod 16 to extend, driving the pressing strip 17 to squeeze the threshing roller 3. Then the threshing roller 3 and the hook-shaped protrusion 4 rotate, and the grains are separated. Some grains contact the buffer block 7, which can provide buffering, prompting the grains to fall from the gap between the buffer block 7 and the threshing roller 3. At the same time, the first fan 6 provides guidance. During the falling process, the second fan 11 draws external wind into the threshing box 1. At this time, the grains fall on the receiving plate 9 and gradually fall. The debris and dust fall into the storage frame 12 from the gap between the receiving plate 9 and the threshing roller 3. At the same time, by providing the blocking rod 19, it can block the broken straw and improve the quality of the grains.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

[0024] Other parts not described in detail in the present invention belong to the prior art, so they will not be elaborated here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
