DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a threshing device for corn storage comprises a corn thresher 1; a feeding port 11 is provided on the top of the corn thresher 1; a first threshing stick 12 is rotatably connected to the middle of the corn thresher 1; a second threshing stick 13 is rotatably connected to the middle of the corn thresher 1; belts 14 are connected to the ends of the first threshing stick 12 and the second threshing stick 13; a servo motor 15 is connected to the end of the first threshing stick 12; a chute 16 is provided in the middle of the corn thresher 1; a screen 17 is slidably connected to the middle of the chute 16; sliding posts 18 are fixedly connected to both sides of the screen 17; The middle of the slide column 18 is connected to a support plate 19; the end of the slide column 18 is fixedly connected to a U-shaped plate 111; the middle of the discharge port 11 is rotatably connected to a roller 112; both sides of the corn thresher 1 are fixedly connected to an L-shaped plate 113; the middle of the L-shaped plate 113 is fixedly connected to an electric push rod 114; the end of the electric push rod 114 is connected to a slider 115; when working, the corn to be threshed is first put into the corn thresher 1 from the discharge port 11, and then the servo motor 15 is operated to drive the first threshing rod 12 to rotate, and when the first threshing rod 12 rotates, it drives the belt 14 rotates, and due to the friction factor, the belt 14 can drive the second threshing roller 13 to rotate when rotating, so that the corn inside the corn thresher 1 can be threshed, and the threshed corn kernels will fall to the screen 17, at this time, the electric push rod 114 works and drives the slider 115 to push forward and backward at the slide groove 16, and the push of the slider 115 squeezes the roller 112 and makes the roller 112 rotate on the surface of the slider 115, and when the roller 112 is squeezed, it drives the slide post 18 to slide up and down in the middle of the support plate 19, and the slide post 18 pushes the screen 1 when sliding. 7 moves up and down in the middle of the slide 16 to screen the corn kernels after threshing. In this step, the servo motor 15 drives the first threshing rod 12 and the second threshing rod 13 to thresh the corn, which can make the surface of the corn more closely attached during storage, thereby reducing the contact area between the corn and the air and prolonging the time required for oxidation, thereby improving the storage shelf life of the corn. The electric push rod 114 can push the screen 17 to preliminarily screen the corn and the stones, straws and other debris contained in the corn, thereby improving the efficiency of the subsequent corn kernel removal work.

[0026] like Figure 1 , Figure 5As shown, a storage box 2 is connected to the middle of the feed opening 11; a baffle 21 is hinged on the inner side wall of the storage box 2; a plurality of first hinges 22 are connected to the side wall of the baffle 21; a threaded sleeve 23 is connected to the middle of the storage box 2; a threaded rod 24 is rotatably connected to the middle of the threaded sleeve 23; a cross plate 25 is connected to the end of the threaded rod 24; during operation, since the amount of corn thresher 1 that can be threshed each time is limited, when the corn inside the corn thresher 1 is filled to a certain amount, it is necessary to stop feeding corn. At this time, the end of the threaded rod 24 can be held and twisted to push the threaded rod 24 into the threaded sleeve 23, and the threaded rod 24 will drive the cross plate 25 to move into the storage box 2 when pushed in. When the cross plate 25 moves to a certain position, it will press against the first hinge 22. At this time, the first hinge 22 will move upward under the force of being pushed and the action of the baffle 21. The corn can be put into the middle of the storage box 2 by moving the screw rod 24 to block the storage box 2. At that time, the rotation of the screw rod 24 can be stopped, and the corn can be put into the middle of the storage box 2. When the corn thresher 1 completes threshing the corn inside it, the screw rod 24 can be twisted to push the cross plate 25 back and thereby move the first hinge 22 downward. At this time, the corn inside the storage box 2 will fall into the corn thresher 1. This step can be used to store the next batch of corn that needs to be threshed in advance through the opening of the storage box 2, thereby preventing the situation that when the corn thresher 1 is used to perform continuous threshing of the corn, the next batch of corn needs to be threshed until the staff puts the corn into the corn thresher 1 one by one, which causes the working time to be extended, the threshing rate to be reduced, and the work efficiency to be affected. At this time, the storage box 2 can be used to speed up the rate of secondary corn delivery, thereby improving the work efficiency.

[0027] like Figure 1 , Figure 6 As shown, a suction fan 3 is connected to one side of the corn thresher 1; a cross support frame 31 is fixedly connected to the middle of the suction fan 3; a rotating shaft 32 is rotatably connected to the middle of the cross support frame 31; a plurality of fan blades 33 are fixedly connected to the middle of the rotating shaft 32; when working, the cross support frame 31 plays a role of supporting the rotating shaft 32. When the suction fan 3 is needed to work, the rotating shaft 32 will rotate and thereby drive the fan blades 33 to rotate. The rotation of the fan blades 33 will form a certain suction force, thereby discharging dust to the outside. This step is that when the screen 17 screens the corn kernels, the dust contained in the corn kernels will be affected by the shaking and float four times. At this time, the dust can be discharged to the outside through the opening of the suction fan 3, thereby preventing the dust from being easily integrated into the corn kernels again if it is not processed. Therefore, when the corn kernels are stored subsequently, the dust is easy to corrode the corn kernels, so as to affect the quality of the corn kernels and increase the probability of corn mildew.

[0028] like Figure 1As shown, the corn thresher 1 has a door 4 hinged on the side; a plurality of second hinges 41 are connected to one side of the door 4; a handle 42 is fixedly connected to one side of the door 4; a transparent observation window 43 is provided in the middle of the door 4; during operation, when the door 4 needs to be opened, the handle 42 can be first grasped and pulled, and the door 4 will expand outward under the action of the second hinge 41 and the pulling force, so that the door 4 can be opened. This step can facilitate the collection of the threshed corn by opening the door 4, and the parts inside the corn thresher 1 can also be inspected, maintained and serviced by opening the door 4. The transparent observation window 43 can facilitate workers to observe the accumulation of corn kernels inside the corn thresher 1, so as to determine when they need to be collected.

[0029] like Figure 2 , Figure 3 As shown, both sides of the inner wall of the corn thresher 1 are fixedly connected with limit plates 51; both sides of the screen 17 are connected with multiple groups of first tension springs 5; during operation, when the screen 17 is moved up and down to screen the corn kernels, the first tension spring 5 will expand and contract with the movement of the screen 17, and when the electric push rod 114 pushes the slider 115, the limit plate 51 can limit the forward movement trajectory of the slider 115. This step can enhance the stability of the screen 17 when sliding through the opening of the first tension spring 5, and through the limiting effect of the limit plate 51, it can prevent the slider 115 from sliding out too long, thereby causing its surface to separate from the roller 112, thereby affecting the screening of the corn kernels.

[0030] like Figure 3 , Figure 4 As shown, the bottom of the support plate 19 is connected to a second tension spring 6; during operation, when the slide post 18 and the middle part of the support plate 19 slide upward, the second tension spring 6 will be compressed as the slide post 18 slides, and when the slide post 18 slides down, the second tension spring 6 will rebound. In this step, the second tension spring 6 can rebound when the slide post 18 slides downward, thereby helping the slide post 18 to slide more stably.

[0031] like Figure 1 As shown, an arc plate 7 is fixedly connected to one side of the corn thresher 1; when working, the servo motor 15 will produce a certain vibration. At this time, the arc plate 7 can limit the vibration frequency and amplitude of the servo motor 15. This step can prevent the servo motor 15 from vibrating too fast or too large, which may affect the rotation of the first threshing roller 12 and the second threshing roller 13, thereby reducing the threshing rate of the first threshing roller 12 and the second threshing roller 13.

[0032] Working principle: during operation, the corn to be threshed is first put into the corn thresher 1 from the feeding port 11, and then the servo motor 15 is operated to drive the first threshing rod 12 to rotate. When the first threshing rod 12 rotates, it drives the belt 14 to rotate, and due to the friction factor, the belt 14 can drive the second threshing rod 13 to rotate when rotating, so that the corn inside the corn thresher 1 can be threshed. The threshed corn kernels will fall to the screen 17. At this time, the electric push rod 114 is operated and drives the slider 115 to push back and forth at the slide 16. The push of the slider 115 will squeeze the roller 112 and make the roller 112 rotate on the surface of the slider 115, and when the roller 112 is squeezed, it will bring The movable sliding column 18 slides up and down in the middle of the support plate 19. When the sliding column 18 slides, it pushes the screen 17 to move up and down in the middle of the slide 16, so that the corn kernels after threshing can be screened. In this step, the servo motor 15 drives the first threshing rod 12 and the second threshing rod 13 to thresh the corn, which can make the surface of the corn more closely fit during storage, thereby reducing the contact area between the corn and the air and prolonging the time required for oxidation, thereby improving the storage shelf life of the corn. The electric push rod 114 can push the screen 17, so that the corn and the stones, straw and other debris contained in the corn can be preliminarily screened, thereby improving the efficiency of the subsequent removal of impurities from the corn kernels. During operation, the amount of corn thresher 1 threshed each time The storage box 2 is limited, so when the corn inside the corn thresher 1 is filled to a certain amount, it is necessary to stop feeding the corn. At this time, the end of the threaded rod 24 can be held and twisted to push the threaded rod 24 into the threaded sleeve 23, and the threaded rod 24 will drive the cross plate 25 to move into the storage box 2 when it is pushed in. When the cross plate 25 moves to a certain position, it will support the first hinge 22. At this time, the first hinge 22 will move upward under the push of the force and the action of the baffle 21, thereby blocking the storage box 2. At this time, the threaded rod 24 can be stopped from rotating, and the corn can be put into the middle of the storage box 2. When the corn thresher 1 has completed threshing the corn inside it, the threaded rod 24 can be twisted to push the cross plate 25 back and thereby move the first hinge 22 downward. At this time, the storage box 2 The corn will fall into the corn thresher 1. This step can be used to store the next batch of corn that needs to be threshed in advance by opening the storage box 2, thereby preventing the situation that when the corn thresher 1 is used to perform continuous threshing of corn, the next batch of corn needs to be threshed after waiting for the staff to put the corns into the corn thresher 1 one by one, which will extend the working time, reduce the threshing rate, and affect the work efficiency. At this time, the storage box 2 can speed up the rate of secondary corn feeding, thereby improving the work efficiency. During operation, the cross support frame 31 supports the rotating shaft 32. When the suction fan 3 is needed to work, the rotating shaft 32 will rotate and drive the fan blades 33 to rotate.The rotation of the fan blades 33 will form a certain suction force, so that the dust can be discharged to the outside. This step is that when the screen 17 screens the corn kernels, the dust contained in the corn kernels will be affected by the shaking and float four times. At this time, the dust can be discharged to the outside through the opening of the suction fan 3, thereby preventing the dust from being easily integrated into the corn kernels again if it is not processed. As a result, when the corn kernels are stored later, the dust is easy to corrode the corn kernels, thereby affecting the quality of the corn kernels and increasing the probability of the corn becoming moldy. During operation, when it is necessary to open the machine door 4, you can first hold the handle 42 and pull it. The timing door 4 will expand outwards under the action of the second hinge 41 and the pulling force, so that the machine door 4 can be opened. This step can facilitate the collection of the threshed corn by opening the machine door 4. At the same time, the parts inside the corn thresher 1 can also be inspected, maintained and serviced by opening the machine door 4. The transparent observation window 43 can be opened to facilitate workers to observe the accumulation of corn kernels inside the corn thresher 1, so as to determine when they need to be collected. During operation, when the screen 17 moves up and down to screen the corn kernels, the first tension spring 5 will expand and contract with the movement of the screen 17, and when the electric push rod 114 When the slider 115 is pushed, the limit plate 51 can limit the forward movement trajectory of the slider 115. This step can enhance the stability of the screen 17 when sliding through the opening of the first tension spring 5. The limiting effect of the limit plate 51 can prevent the slider 115 from sliding out too long, thereby causing its surface to separate from the roller 112, thereby affecting the screening of corn kernels. During operation, when the slide post 18 and the middle part of the support plate 19 slide up, the second tension spring 6 will be compressed as the slide post 18 slides, and when the slide post 18 slides down, the second tension spring 6 will be compressed. In this step, the second tension spring 6 can rebound when the slide column 18 slides downward, so as to help the slide column 18 slide more stably. When working, the servo motor 15 will produce a certain vibration. At this time, the arc plate 7 can limit the vibration frequency and amplitude of the servo motor 15. In this step, the arc plate 7 can prevent the servo motor 15 from vibrating too fast or too large, which may affect the rotation of the first threshing rod 12 and the second threshing rod 13, thereby reducing the threshing rate of the first threshing rod 12 and the second threshing rod 13.
