Description

Technical Field

[0001] This invention relates to the field of threshing machine technology, specifically to a threshing machine equipped with an anti-splash structure. Background Technology

[0002] A thresher is an agricultural machine widely used for separating grains and grain stalks. Threshers can not only quickly separate the grains of various cereal crops, but also improve grain yield and processing efficiency. A threshing machine, such as one disclosed in CN106385988A, includes a first roller group, a second roller group, and a third roller group. A screen is provided between the first and second roller groups, and a first discharge hopper is located below the screen. A rotating threshing roller and screen are provided between the second and third roller groups, and a second discharge hopper is located below the threshing roller and screen. A shearing mechanism is provided after the third roller group. By adopting a threshing method that combines rolling and beating, the threshing effect is good, especially suitable for threshing wheat, rice, and rapeseed. The shearing mechanism can automatically crush straw, realizing multiple functions and reducing labor intensity while improving labor efficiency. This threshing machine has a compact structure, is easy to process and produce, and is suitable for use in mountainous areas. For example, the corn thresher with publication number CN100358408C uses an axial flow propulsion method for corn threshing. The axial flow propulsion force is generated by the axial thrust produced by the nail teeth fixed on the surface of the drum shaft at a certain angle to the radial direction of the drum shaft. Its threshing device consists of a feed hopper 1, a main drum shaft 2, an auxiliary drum shaft 3, a pusher 4, an elevator 5, a slag discharger 6, a clutch pull rod assembly 7, a machine body 8, a clutch 9, a clutch bend wall 10, a drum screen 11, nail teeth 12, a slag throwing plate 13, and a power transmission mechanism. The nail teeth 12 are fixed on the outer surface of the main drum shaft 2, perpendicular to the axial direction of the main drum shaft 2, and radially deflected clockwise by 5-10 degrees. The nail teeth 12 are also fixed on the outer surface of the auxiliary drum shaft 3, perpendicular to the axial direction of the auxiliary drum shaft 3, and radially deflected counterclockwise by 5-10 degrees. This corn thresher removes kernels cleanly, removing 98% of impurities and completely separating them from the kernels. It has a low kernel breakage rate, and the kernels are completely separated before and after threshing. It has high production efficiency and can thresh kernels with the husk on. Another corn thresher, disclosed in CN108093882A, includes a support frame, a thresher body mounted on the support frame, and a corn feeder for feeding corn into the thresher body. The thresher body includes a feed inlet, a housing located below the feed inlet, a threshing blade assembly disposed within the housing, and a separation device disposed below the housing. The threshing blade assembly includes an annular blade holder mounted within the housing in a manner rotatable about its axis, multiple threshing blades evenly distributed along the circumference of the blade holder and elastically connected to the blade holder axially, and a drive device for driving the blade holder to rotate. The separation device includes an inclined separation plate with screening openings that allow corn kernels to pass through but prevent corn cobs from passing through. This thresher has a compact structure, low cost, and can be used for small-batch corn threshing. During use, after the threshing machine threshes the grain, the grain will scatter out of the discharge port. However, the threshing machine in the above application does not have a good structure to prevent grain from splashing. As a result, the scattered grain will affect the subsequent collection work of the staff and cause unnecessary trouble. At the same time, there may be a lot of dust during use. The device in the above application does not have a dust control structure, which will affect the working environment of the staff and be detrimental to their health.

[0003] To address the aforementioned issues, there is an urgent need for innovative design based on the existing threshing machine. Summary of the Invention

[0004] The purpose of this invention is to provide a threshing machine with an anti-splash structure to solve the problems mentioned in the background art, such as the lack of a good anti-splash structure for grains during use, which leads to scattered grains affecting the subsequent collection work of workers and causing unnecessary trouble for workers, and the lack of a dust control structure during use, which affects the working environment of workers and is detrimental to their health.

A threshing machine equipped with an anti-splash structure further includes: The motor is fixedly connected to the upper surface of the base plate, and the output end of the motor is fixedly connected to a connecting shaft, and a second pulley is sleeved on the surface of the connecting shaft. Side rods are fixedly connected to the surface of the limiting frame, and the side rods are symmetrically distributed about the center of the limiting frame; An upper connecting plate is fixedly connected to the surface of the side rod, and a lower connecting plate is fixedly connected to the end of the side rod; A rotating shaft, which is rotatably disposed inside the support plate; A protective frame is fixedly connected to the upper surface of the base plate, and a fixing plate is fixedly connected to the upper surface of the base plate, and a long pin is rotatably provided inside the fixing plate. The second bevel gear is fixedly connected to the end of the long pin; A connecting plate is fixedly connected to the inner wall of the protective frame, and a drive shaft is rotatably installed inside the connecting plate, with a fan fixedly connected to the end of the drive shaft.

[0006] Preferably, a first pulley is sleeved and connected to the end of the connecting shaft, and the other side of the first pulley is sleeved and connected to the surface of the transmission roller.

[0007] Preferably, the other side of the second pulley is sleeved and connected to the surface of the rotating shaft, and a push rod is fixedly connected to the right end of the rotating shaft, and the push rods are evenly distributed on the surface of the rotating shaft.

[0008] Preferably, the left side of the limiting frame is fixedly connected to a side connecting rod corresponding to the push rod, and the end of the side connecting rod is a frustum structure.

[0009] Preferably, a limiting rod is fixedly connected to the inner wall of the support plate, and the limiting rod passes through the interior of the unloading frame, and the limiting rod is symmetrically distributed about the center of the unloading frame.

[0010] Preferably, an auxiliary plate is fixedly connected to the end of the limiting rod, and a reset spring that plays an elastic reset role is fixedly connected to the surface of the auxiliary plate. The other side of the reset spring is fixedly connected to the surface of the limiting frame, and the upper surface of the feeding frame is in contact with the lower surface of the working box.

[0011] Preferably, a filter screen is fixedly connected to the inner wall of the upper plate, and both sides of the upper plate and both sides of the lower plate are protruding, and the upper plate and the lower plate are inclined, and the feeding positions of the upper plate and the lower plate are opposite.

[0012] Preferably, a first bevel gear corresponding to the second bevel gear is fixedly connected to the surface of the connecting shaft, and the long pin passes through the interior of the fixing plate.

[0013] Preferably, a main gear is fixedly connected to the end of the long pin, and a secondary gear that meshes with the main gear is fixedly connected to the end of the transmission shaft.

[0014] Preferably, the front view of the protective frame is an inverted "U" shape, and a protective net is fixedly connected to the inner wall of the protective frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This threshing machine with an anti-splash structure adopts a novel structural design. Through the setting of the feeding frame and the limiting frame, the entire device has an anti-splash function. At the same time, through the setting of the reciprocating structure, the side connecting rod, the limiting frame, the feeding frame, the upper connecting plate, the filter screen, and the lower connecting plate also make reciprocating linear motion during feeding, which improves the feeding speed. Meanwhile, the fan sucks away the dust, ensuring the working environment of the personnel at the feeding plate position. The specific details are as follows: (1) The thresher equipped with an anti-splash structure starts the motor when threshing corn. The motor drives the transmission roller to rotate through the first belt pulley. The transmission roller then drives the material from the receiving plate into the working box, where it is processed by the transmission roller and the detachment component. Finally, the material is discharged from the working box through the feeding frame and the limiting frame, completing the most basic threshing work. Furthermore, during the feeding process, straw and grain fall simultaneously from the feeding frame and the limiting frame. The filter screen on the inner wall of the upper receiving plate separates the straw and grain. The straw is discharged from the end of the upper receiving plate, while the grain falls from the filter screen onto the lower receiving plate and is eventually collected by the staff at the end of the lower receiving plate. The feeding frame and the limiting frame play a role in preventing splashing. (2) When the motor is working, the motor drives the rotating shaft to rotate through the second pulley. When the rotating shaft rotates, it will drive the push rod to rotate synchronously. As a result, the push rod will intermittently contact the side connecting rod. At this time, the side connecting rod, the limiting frame, the feeding frame, the upper connecting plate, the filter screen and the lower connecting plate will all reciprocate linearly in the horizontal direction under the action of the push rod, the return spring and the auxiliary plate. At this time, the limiting frame, the feeding frame, the upper connecting plate, the filter screen and the lower connecting plate can feed materials better. Furthermore, during the movement of the limiting frame, the unloading frame, the upper plate, the filter screen, and the lower plate, the limiting rod ensures that the limiting block and the unloading frame move only in the horizontal direction, thus guaranteeing stability. (3) The threshing machine with anti-splash structure, when the motor and connecting shaft rotate, the connecting shaft drives the long pin to rotate through the first bevel gear and the second bevel gear. When the long pin rotates, it drives the transmission shaft to rotate through the main gear and the auxiliary gear, and then the fan rotates synchronously. At this time, the fan generates negative pressure, sucking the dust away from the bottom plate, ensuring the working environment of the staff at the feed plate position. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 The present invention provides the following technical solution: a threshing machine equipped with an anti-splash structure: Example 1: The basic corn threshing process can be completed through the feeding plate 5, working box 3, and unloading frame 9. Figures 1-2 As shown: It includes a base plate 1 and a feed plate 5. A bracket is fixedly connected to the lower surface of the base plate 1, and a support plate 2 is fixedly connected to the upper surface of the base plate 1. A working box 3 is fixedly connected inside the support plate 2, and a transmission roller 4 is rotatably arranged inside the working box 3. At the same time, a release component is provided on the surface of the transmission roller 4. The feed plate 5 is fixedly connected to the surface of the working box 3, and a feeding frame 9 is fixedly connected to the lower surface of the working box 3. A limit frame 10 is fixedly connected to the lower surface of the feeding frame 9. A threshing machine equipped with an anti-splash structure further includes: Motor 6 is fixedly connected to the upper surface of base plate 1, and the output end of motor 6 is fixedly connected to connecting shaft 7. A second pulley 16 is sleeved and connected to the surface of connecting shaft 7. Side rod 11 is fixedly connected to the surface of limiting frame 10, and the side rod 11 is symmetrically distributed about the center of limiting frame 10. The upper connecting plate 12 is fixedly connected to the surface of the side rod 11, and the end of the side rod 11 is fixedly connected to the lower connecting plate 14 and the rotating shaft 15, which is rotatably arranged inside the support plate 2. The protective frame 26 is fixedly connected to the upper surface of the base plate 1, and the upper surface of the base plate 1 is fixedly connected to the fixing plate 25. The fixing plate 25 is rotatably provided with a long pin 23 and a second bevel gear 24, which is fixedly connected to the end of the long pin 23. The connecting plate 32 is fixedly connected to the inner wall of the protective frame 26, and the connecting plate 32 is rotatably provided with a drive shaft 29. The end of the drive shaft 29 is fixedly connected to a fan 30. The end of the connecting shaft 7 is sleeved and connected to a first pulley 8, and the other side of the first pulley 8 is sleeved and connected to the surface of the drive roller 4.

[0020] When threshing corn, the motor 6 is started. The motor 6 drives the transmission roller 4 to rotate through the first pulley 8. The transmission roller 4 then drives the material from the feed plate 5 into the working box 3, where it is processed by the transmission roller 4 and the detachment component. Finally, the material is discharged from the working box 3 through the discharge frame 9 and the limiting frame 10, completing the most basic threshing work. The discharge frame 9 and the limiting frame 10 play a role in limiting the falling distance of the material during operation, that is, they play a role in preventing splashing.

[0021] Example 2: Unlike Example 1, the push rod 17 and the return spring 21 are used to keep the feeding frame 9 and the limiting frame 10 in a reciprocating linear motion state, which facilitates the material discharge work of the upper connecting plate 12 and the lower connecting plate 14. Figures 3-7 As shown: The other side of the second pulley 16 is sleeved and connected to the surface of the rotating shaft 15, and a push rod 17 is fixedly connected to the right end of the rotating shaft 15. The push rods 17 are evenly distributed on the surface of the rotating shaft 15. A side connecting rod 18 corresponding to the push rod 17 is fixedly connected to the left side of the limiting frame 10, and the end of the side connecting rod 18 is a frustum structure.

[0022] A limiting rod 19 is fixedly connected to the inner wall of the support plate 2, and the limiting rod 19 passes through the interior of the unloading frame 9. The limiting rod 19 is symmetrically distributed about the center of the unloading frame 9. An auxiliary plate 20 is fixedly connected to the end of the limiting rod 19, and a reset spring 21 that plays an elastic reset role is fixedly connected to the surface of the auxiliary plate 20. The other side of the reset spring 21 is fixedly connected to the surface of the limiting frame 10. The upper surface of the unloading frame 9 is in contact with the lower surface of the working box 3.

[0023] A filter screen 13 is fixedly connected to the inner wall of the upper plate 12, and both sides of the upper plate 12 and the lower plate 14 are protruding. The upper plate 12 and the lower plate 14 are both inclined, and the feeding positions of the upper plate 12 and the lower plate 14 are opposite.

[0024] During the feeding process, straw and grain fall simultaneously from the feeding frame 9 and the limiting frame 10. The filter screen 13 on the inner wall of the upper receiving plate 12 separates the straw and grain. The straw falls from the end of the upper receiving plate 12, while the grain falls from the filter screen 13 onto the lower receiving plate 14. Finally, the grain is collected by the workers at the end of the lower receiving plate 14. When the motor 6 is working, the motor 6 drives the rotating shaft 15 to rotate inside the support plate 2 via the second pulley 16. When the rotating shaft 15 rotates, it drives the push rod 17 to rotate synchronously. As a result, the push rod 17 will intermittently contact the side connecting rod 18. When the push rod 17 contacts the side connecting rod 18, the side connecting rod 18, the limiting frame 10, the feeding frame 9, the upper receiving plate 12, the filter screen 13, and the lower receiving plate 14 will... Under the action of the limiting rod 19, it moves horizontally towards the direction of squeezing the return spring 21. At this time, the return spring 21 is squeezed by the limiting frame 10 and the auxiliary plate 20. When the push rod 17 rotates to the point where it does not contact the side connecting rod 18, the side connecting rod 18, the limiting frame 10, the unloading frame 9, the upper connecting plate 12, the filter screen 13 and the lower connecting plate 14 will return to their original positions under the action of the return spring 21. The above process is repeated. At this time, the side connecting rod 18, the limiting frame 10, the unloading frame 9, the upper connecting plate 12, the filter screen 13 and the lower connecting plate 14 will all make reciprocating linear motion in the horizontal direction. At this time, the limiting frame 10, the unloading frame 9, the upper connecting plate 12, the filter screen 13 and the lower connecting plate 14 are all in a state of vibration, which can better unload materials and improve work efficiency.

[0025] Example 3: Unlike Example 2, the fan 30 is used to draw dust generated during processing away from the base plate 1, thereby providing a better working environment for workers at the feed plate 5. Figures 8-10As shown: A first bevel gear 22 corresponding to the second bevel gear 24 is fixedly connected to the surface of the connecting shaft 7. A long pin 23 passes through the interior of the fixed plate 25. A main gear 28 is fixedly connected to the end of the long pin 23. A secondary gear 31 that meshes with the main gear 28 is fixedly connected to the end of the transmission shaft 29. The front view of the protective frame 26 is an inverted "U" shape, and a protective net 27 is fixedly connected to the inner wall of the protective frame 26.

[0026] When the motor 6 and the connecting shaft 7 rotate, the connecting shaft 7 drives the long pin 23 to rotate through the first bevel gear 22 and the second bevel gear 24. When the long pin 23 rotates, it drives the transmission shaft 29 to rotate through the main gear 28 and the auxiliary gear 31, and then the fan 30 rotates synchronously. At this time, the fan 30 generates negative pressure, which sucks the dust away from the bottom plate 1, ensuring the working environment of the staff at the feed plate 5. During the rotation of the main gear 28, the auxiliary gear 31 and the fan 30, the protective net 27 on the inner wall of the protective frame 26 plays a protective role, preventing the main gear 28, the auxiliary gear 31 and the fan 30 from contacting the outside staff.

[0027] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
