Description

Technical Field

[0001] The utility model belongs to the technical field of seed cultivation, and in particular relates to a bad seed removing device for rice seed cultivation. Background Art

[0002] When cultivating rice, it is necessary to screen the rice seeds and remove the damaged and dead seeds to improve the germination rate and seedling quality and ensure the yield and quality of the crop. Bad seeds often have damaged internal structures and may have cavities, rot or be infested by pests, which will cause their quality and density to be smaller than normal healthy seeds.

[0003] Wind screening is a commonly used method for removing bad seeds. A fan is used to blow the falling seeds so that the bad seeds with lighter empty shells can be blown to the outside of the equipment. The bad seed removal machine uses a funnel to lower the rice seeds. The amount and frequency of seed falling are difficult to control, which sometimes causes a large amount of seeds to fall. The wind force of the fan is difficult to remove the bad seeds mixed in the seeds, resulting in a low bad seed removal rate. In addition, some bad seed removal machines directly discharge bad seeds and impurities to the outside of the equipment, which is easy to pollute the external environment and reduce the quality of the working environment for workers. Utility Model Content

[0006] Among them, the inner walls of several material taking troughs are slidably connected with push plates, and the inner walls of the push plates are fixedly connected with counterweight core plates.

[0007] Among them, one end of several of the push plates is fixedly connected to two limit pull ropes for limiting the push plates, and the limit pull ropes are fixedly connected to the corresponding inner walls of the material taking trough.

[0008] Among them, a plurality of cavities are opened in the seed bin, and the plurality of cavities are not connected with the internal space of the seed bin and the bad seed removal machine.

[0009] Among them, a lower bin is arranged in the waste box, the upper bin is connected with the internal space of the lower bin, and a bad seed discharge port corresponding to the position of the lower bin is installed on one side of the waste box.

[0010] The beneficial effects of the utility model are as follows: by controlling the rotation speed of the rotating drum, the falling amount and frequency of seed release can be controlled, so that the number of seeds released each time can be kept uniform, avoiding the situation where sometimes a large number of seeds fall, and the wind force of the fan is difficult to remove the bad seeds mixed in the seeds, resulting in a low bad seed removal rate. The bad seeds and impurities are intercepted by the interception net to prevent the bad seeds and impurities from being directly discharged to the outside of the equipment, avoiding pollution to the external environment, and improving the quality of the working environment for workers.

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 5The utility model provides the following technical solutions: it includes a bad seed removal machine 1 and a seed bin 2, the inner wall of the seed bin 2 is rotatably connected with a rotating drum 21, the side wall of the rotating drum 21 is provided with a plurality of material taking troughs 22, the bottom of the seed bin 2 is provided with a discharge port 23, the material taking trough 22 is communicated with the internal space of the bad seed removal machine 1 through the discharge port 23, one side of the bad seed removal machine 1 is fixedly connected with a waste box 3, an upper bin 31 is arranged in the waste box 3, one side of the waste box 3 is provided with an exhaust hole 311 corresponding to the position of the upper bin 31, the inner wall of the exhaust hole 311 is fixedly connected with an interception net 312, the inner wall of the upper bin 31 is rotatably connected with a driving rod 33, the side wall of the driving rod 33 is fixedly connected with a plurality of scrapers 331, the scrapers 331 are rotatably connected to the inner wall of the upper bin 31, and the scrapers 331 are slidably connected to one side of the interception net 312.

[0019] In this embodiment: the bad seed removal machine 1 supports each component of the device, the seed bin 2 stores and accommodates the seeds to be screened, the rotating drum 21 is designed to rotate, and a motor for driving the rotating drum 21 is installed on one side of the bad seed removal machine 1. The rotating drum 21 is connected to the internal space of the seed bin 2 through a plurality of feeding troughs 22. The seeds in the seed bin 2 slide down and fill the feeding trough 22, so that the feeding trough 22 can accommodate a certain amount of seeds. The volumes of the plurality of feeding troughs 22 are the same, so that the plurality of feeding troughs 22 can accommodate the same amount of seeds. By controlling the rotation The drum 21 rotates, and the rotating drum 21 drives the seeds contained in the feeding trough 22 to rotate downward. When the feeding trough 22 rotates to the bottom and is aligned with the discharge port 23, the opening of the feeding trough 22 is no longer blocked by the seed bin 2, so that the seeds transported from the feeding trough 22 can be put into the internal space of the bad seed remover 1, and the fan inside the bad seed remover 1 blows the falling seeds. By controlling the rotation speed of the rotating drum 21, the falling amount and frequency of the seed release can be controlled, so that the number of seeds released each time can be kept uniform, avoiding the seeds from falling sometimes. The wind force of the fan is difficult to remove the bad seeds mixed in the seeds, resulting in a low bad seed removal rate. In addition, the internal shape of the material trough 22 allows the seeds to fall in an orderly manner from bottom to top, improves the ability of the seeds to be evenly dispersed, and is conducive to the wind to remove the bad seeds. The bad seed removal machine 1 supports the waste box 3, and the wind blows the bad seeds into the internal space of the upper warehouse 31. The exhaust hole 311 discharges excess air, and the interception net 312 intercepts the bad seeds and impurities to prevent the bad seeds and impurities from being directly discharged to the outside of the equipment, avoiding pollution to the external environment and improving the working environment of the workers. The waste bin 3 supports the driving rod 33, which supports and drives a plurality of scrapers 331 to rotate. The driving rod 33 is driven to rotate by a motor outside the waste bin 3. When the driving rod 33 drives the scraper 331 to rotate, the scraper 331 can scrape the bad seeds and impurities intercepted by the interception net 312, so that the interception net 312 can be cleaned, and the bad seeds and impurities are prevented from clogging the interception net 312, so that the airflow can be discharged stably, and the scraper 331 drives the scraped bad seeds and impurities to rotate downward and discharge, which is beneficial to the continuous filtering work of the interception net 312.

[0020] The inner walls of several feeding troughs 22 are all slidably connected with push plates 24, and the inner walls of the push plates 24 are fixedly connected with counterweight core plates 241; when the feeding trough 22 opens upward, the push plates 24 use the counterweight core plates 241 to increase their own weight, making it easier for the push plates 24 to slide downward by gravity. The push plates 24 inside the feeding trough 22 can use gravity to slide to the deep inside of the feeding trough 22. At this time, the internal space of the feeding trough 22 is emptied, and the seeds inside the seed bin 2 are filled into the feeding trough 22. The seed bin 2 drives the feeding trough 22 to rotate until the opening faces downward, and then the seeds are discharged. The push plates 24 slide downward under the influence of gravity, so that the push plates 24 can push the seeds on the inner wall of the feeding trough 22 for discharge, thereby preventing the seeds from remaining inside the seed bin 2.

[0021] One end of each of the push plates 24 is fixedly connected to two limit ropes 25 for limiting the push plates 24, and the limit ropes 25 are fixedly connected to the inner wall of the corresponding material collection trough 22; a recessed area is provided on the side of the push plate 24 close to the limit ropes 25, and the push plate 24 uses the recessed area to make way for the limit ropes 25, and when the push plate 24 slides downward, the push plate 24 stretches the limit ropes 25 to straighten them, and when the push plate 24 reaches the opening position of the material collection trough 22, the limit ropes 25 pull and limit the push plate 24 to prevent the push plate 24 from detaching from the material collection trough 22.

[0022] A plurality of cavities 26 are provided in the seed bin 2, and the plurality of cavities 26 are not connected with the internal space of the seed bin 2 and the bad seed removal machine 1; the cavity 26 is isolated from the bad seed removal machine 1 and the seed bin 2 so that the seeds will not enter the internal space of the cavity 26, thereby preventing the seeds from remaining in the cavity 26. The plurality of cavities 26 can reduce the weight of the rotating drum 21 and reduce the driving load problem caused by the equipment quality.

[0023] A lower bin 32 is provided in the waste box 3, and the upper bin 31 is connected to the internal space of the lower bin 32. A bad seed discharge port 34 corresponding to the position of the lower bin 32 is installed on one side of the waste box 3; when the space between the two scrapers 331 rotates downward, the bad seeds and impurities scraped between the two driving rods 33 can be dropped into the lower bin 32, and the lower bin 32 stores the bad seeds and impurities in a centralized manner for centralized treatment. The bad seed discharge port 34 is at the bottom position of one side of the waste box 3. When the bad seed discharge port 34 is opened, the bad seeds in the lower bin 32 can be discharged.

[0024] The working principle and use process of the utility model are as follows: when the seeds are screened, the seeds inside the seed bin 2 are filled into the feeding trough 22, the control motor drives the rotating drum 21 to rotate, the seed bin 2 drives the feeding trough 22 to rotate downward, so that the opening of the feeding trough 22 can face downward, and the seeds are discharged into the bad seed removal machine 1 through the discharge port 23 under the influence of gravity, and the push plate 24 slides downward under the influence of gravity, so that the push plate 24 can push the seeds on the inner wall of the feeding trough 22 to be discharged, and prevent the seeds from remaining in the seed bin 2. When the push plate 24 reaches the opening position of the feeding trough 22, the limit pull rope 25 pulls the push plate 24 to limit the position, so as to prevent the push plate 24 from falling out of the feeding trough 22. The fan inside the bad seed removal machine 1 blows the falling seeds, and the interception net 312 intercepts the bad seeds and impurities to prevent them from being directly discharged to the outside of the equipment, avoid polluting the external environment, and improve the quality of the working environment for workers. The control motor drives the driving rod 33 to rotate, and the driving rod 33 drives the scraper 331 to rotate. The scraper 331 can scrape the bad seeds and impurities intercepted by the interception net 312, so that the interception net 312 can be cleaned, and the bad seeds and impurities are prevented from clogging the interception net 312, so that the airflow discharge can be carried out stably, and the scraper 331 drives the scraped bad seeds and impurities to rotate downward and discharge, which is beneficial to the continuous filtering work of the interception net 312.
