Description

Technical Field

[0001] This utility model relates to the field of threshers, and in particular to an anti-clogging device for a corn thresher. Background Technology

[0002] A corn thresher is an agricultural machine used to separate corn kernels from the cob. It works by mechanically impacting, rubbing, and squeezing the corn cob to achieve the purpose of threshing. During the threshing process, corn cobs, stalks, and other debris can clog the inside of the machine, causing reduced efficiency or equipment damage. Therefore, anti-clogging devices are needed to protect the equipment.

[0003] The main reason for clogging in some existing traditional corn threshers is that corn ears, kernels, and stalks get stuck in the clogging holes and cannot be cleared in time. At the same time, the feeding of existing corn threshers is mostly controlled manually, which makes it difficult to control the feeding speed. However, the feeding speed has a significant impact on the threshing effect of the corn thresher. Too fast or too slow a speed can easily cause clogging or uneven threshing, making it impractical. Therefore, an anti-clogging device for corn threshers is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of an anti-clogging device for a corn thresher, comprising a housing 1, which is the shell of the thresher; a threshing mechanism 3 is provided in the middle of the housing 1 for threshing corn; an anti-clogging component 2 is provided in the middle of the housing 1 for screening corn ears and kernels and preventing clogging during screening; a conveyor 4 is provided at the upper part of the housing 1 for feeding the thresher; a feeding mechanism 5 is provided at the upper part of the conveyor 4 for feeding the thresher; and a screen plate 21 of the anti-clogging component 2 has a number of screen holes at its upper part. Multiple mounting strips 22 are fixedly connected to the front and rear sides of the screen plate 21 for screening corn kernels. These strips are used to connect various components. Slider 23 is fixedly connected to the left and right sides of the mounting strip 22 for connecting the anti-blocking component 2. It is similar to an L-shape and consists of a vertical plate and a horizontal plate. When the screen plate 21 vibrates, the mounting strip 22 can drive the slider 23 to slide. When sliding, the vertical plate can cover the slide groove 15 to prevent material from entering the slide groove 15. Vibrating elements 24 are provided at the front and rear of the mounting strip 22. These elements are used to make the screen plate 21 vibrate during corn threshing, thereby preventing the screen holes from clogging.

[0033] Furthermore, the vibrating component 24 includes a mounting plate 243, which is used to fix the anti-blocking component 2 and to connect various components. The mounting plate 243 is fixedly connected to the inner wall of the outer casing 1. A vertical rod 241 is movably connected through the middle of the mounting plate 243. A limit block is fixed at the lower part of the vertical rod 241 to prevent the vertical rod 241 from detaching from the mounting plate 243. The top of the vertical rod 241 is fixedly connected to the mounting strip 22. A spring 242 is fixedly connected between the mounting strip 22 and the mounting plate 243, which is used to make it vibrate when the corn falls onto the screen plate 21.

[0034] Furthermore, a feed hopper 11 is fixedly connected to the top of the outer shell 1 for feeding. An outlet 12 is provided on the left side of the outer shell 1 for feeding the threshed corn ears out of the outer shell 1. An outlet 13 is provided on the lower front side of the outer shell 1 for feeding out the corn kernels. A guide plate 14 is fixedly connected to the lower part of the outer shell 1. It is inclined to discharge the material and prevent it from piling up. Slide grooves 15 are provided on the front, back, left and right sides of the inner wall of the outer shell 1 for connecting with the slider 23. The slider 23 is slidably connected to the slide groove 15.

[0035] Please see Figure 4 - Figure 6 The conveyor 4 includes a conveyor belt 41, which is used to transport materials. Multiple partitions 42 are fixedly connected to the outer wall of the conveyor belt 41. The distance between the multiple partitions 42 is the same, which is used to ensure uniform feeding.

[0036] Furthermore, the feeding mechanism 5 includes a storage hopper 51 for storing corn to be threshed. The lower left and right sides of the storage hopper 51 are provided with auxiliary openings 511 through which a partition 42 can pass. An mounting frame 52 is fixedly connected to the outside of the storage hopper 51 for securing the feeding mechanism 5 to the conveyor 4. The mounting frame 52 is fixedly connected to the conveyor 4. A discharge assembly 53 is provided at the lower part of the storage hopper 51 for discharging corn from the storage hopper 51. The discharge assembly 53 includes two rotating shafts 531. Discharge rollers 532 are fixedly connected to the outside of the rotating shafts 531 for feeding corn and preventing accumulation. Gears 533 are fixedly connected to the front ends of both rotating shafts 531, and the two gears 533 mesh with each other. A motor 534 is fixedly connected to the rear end of the rotating shaft 531 on the right side for providing power to the assembly. The motor 534 is fixedly connected to the storage hopper 51.

[0037] Working principle: During use, the corn to be threshed is poured into the storage hopper 51, and the conveyor 4 and discharge assembly 53 are simultaneously turned on. When the motor 534 is turned on, the rotating shaft 531 connected to the motor 534 will rotate accordingly. At this time, the gear 533 fixed to the rotating shaft 531 will rotate, thereby driving another gear 533 meshing with it to rotate. The rotating shaft 531 connected to the other gear 533 will also rotate accordingly. When the rotating shaft 531 rotates, the discharge roller 532 fixed to the rotating shaft 531 will also rotate, thus assisting the corn in the storage hopper 51 to fall onto the conveyor 4. Since the conveyor belt 41 of the conveyor 4 is equipped with multiple baffles 42, the baffles 42 can effectively control the amount of corn on the conveyor 4. They can also cooperate with the feeding mechanism 5 to control the feeding speed of the threshing mechanism 3. The conveyor 4 will feed the corn into the outer casing 1 through the feed hopper 11. At this time, the... The threshing mechanism 3 will thresh the corn. The corn kernels will fall through the screen holes on the screen plate 21 into the lower guide plate 14 and be discharged through the discharge port 13. The threshed corn cobs will fall onto the screen plate 21 and be sent out through the discharge port 12. When the corn cobs fall onto the screen plate 21, since the screen plate 21 is connected to the outer shell 1 through the mounting strip 22, and the mounting strip 22 is connected to the outer shell 1 through the slider 23 and the vibrating element 24, the screen plate 21 will move downward under the impact of the corn cobs. At this time, the mounting strip 22 will squeeze the spring 242, and the upright 241 will slide downward. At the same time, the spring 242 will generate a reaction force on the mounting strip 22, thereby pushing the screen plate 21 upward, which will make the screen plate 21 vibrate. This can effectively prevent the corn kernels or corn cobs from blocking the screen holes of the screen plate 21 and causing blockage.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
