Description

Technical Field

[0001] The invention relates to the technical field of corn threshing processing, and in particular discloses a corn cob threshing processing device for complete threshing. Background Art

[0002] In the process of deep processing of corn, corn needs to be threshed first, and then the corn kernels need to be degermed, ground, pressed and other processing procedures. When the traditional corn thresher threshes the corn cobs, the threshing is not clean, and the threshing process of multiple corn cobs at one time will affect each other, resulting in poor threshing effect.

[0003] The invention patent with application number 201410202054.6 discloses a corn thresher, including a box cover arranged on the top of a box seat, a feeding port is arranged at one end of the top of the box cover, a threshing roller is rotatably connected in the box seat, the threshing roller includes a rotating shaft, a filter plate is fixed under the rotating shaft, the filter plate is inclined downward from one end of the feeding port to the other end, a baffle is arranged at the bottom of the end of the filter plate, a corn stalk dropping port is arranged between the baffle and the end of the box seat, and a corn kernel discharge port is arranged at the bottom of the filter plate; a plurality of threshing rods are distributed on the cylindrical surface of the rotating shaft, a plurality of swinging rods are sleeved on the threshing rods, the swinging rods are clearance-matched with the threshing rods, and the rotating shaft is driven by a motor. The corn thresher disclosed in the patent throws corn cobs into one end of the box through the feeding port during operation, and then threshes the corn cobs through the swinging rod, and moves to one side of the corn stalk discharge port during the corn cob threshing process; although the corn thresher realizes the threshing process of corn cobs, it cannot ensure that the corn kernels on the surface of the corn cobs are completely removed during the movement of the corn cobs from the feeding port to the corn stalk discharge port, resulting in serious waste of corn raw materials. In addition, when the corn thresher threshes multiple corns at one time, it will also cause mutual influence inside the box, affecting the threshing effect, and even the corn stalks will be crushed due to the squeezing and kneading effect between them, and then mixed into the corn kernels and transported out together. Therefore, in view of the above-mentioned shortcomings of the existing corn thresher, the present invention proposes a newly designed corn cob threshing processing device to achieve complete threshing of corn cobs and ensure stable operation during the threshing process. Summary of the invention

[0004] The present invention aims to provide a corn cob threshing processing device for complete threshing, so as to achieve complete threshing of corn cobs, and make the simultaneous threshing processes of multiple corn cobs independent of each other without affecting each other, thereby ensuring that each corn cob can be completely threshed.

[0005] The present invention is achieved through the following technical solutions: A complete threshing corn cob threshing processing device comprises a threshing box, a threshing mechanism is arranged in the threshing box, a lifting and conveying mechanism for lifting and loading corn cobs in rows is arranged on one side of the threshing box, and a downwardly inclined material guide plate is arranged at the connection point between the upper end of the lifting and conveying mechanism and the threshing box, and a circular arc baffle is connected to the lower end of the material guide plate; The threshing mechanism comprises a threshing roller assembly arranged at the center of the circular arc baffle, a first shaft rod is fixed in the threshing box on the opposite side of the guide plate, an arc-shaped pressing plate with a lower end extending to the threshing roller assembly is rotatably connected to the first shaft rod, and the distance between the arc-shaped pressing plate and the threshing roller is gradually increased from bottom to top, the back side of each arc-shaped pressing plate is connected to a driving telescopic member through a spring free telescopic rod structure, and the end of a row of driving telescopic members is rotatably connected to the second shaft rod in the threshing box, and each arc-shaped pressing plate is connected to a limit plate extending to the circular arc baffle; A strip is fixed in the threshing box, and a row of pressure sensors corresponding to each arc-shaped pressing plate is installed on the strip. A second spring is connected between the pressure sensor and the back side of the arc-shaped pressing plate. The pressure sensor is electrically connected to a controller, and the driving telescopic member is electrically connected to the controller.

[0006] The corn cob threshing processing device disclosed in the present invention lifts and conveys a plurality of corn cobs in rows at one time by a lifting and conveying mechanism during operation, and then is introduced into the limiting space formed by the arc baffle and the limiting plate by a material guide plate. When the corn cobs between the lower end of the arc-shaped pressing plate and the threshing roller assembly are completely threshed, the diameter of the corn cob core is reduced by about 1 / 3 compared with the corn cob. At this time, when the threshing roller assembly squeezes the corn cob core, the stroke of the corn cob core applied to the second spring and the compression of the second spring is significantly reduced, and then the corresponding pressure sensor detects this signal and feeds it back to the controller, and then the controller actively controls the corresponding driving telescopic member to shorten it.

[0007] During the process of driving the telescopic part to retract, the arc-shaped pressing plate will rotate around the first shaft toward the side away from the threshing roller assembly. At this time, the limiting plate connected to the arc-shaped pressing plate rotates to the bottom of the circular arc baffle, so that the corn cob supported above can fall through the gap. After the corn cob falls, the driving telescopic part is immediately controlled to extend and reset. On the one hand, it hinders the corn cob that continues to fall from the top, so that there is only one corn cob that interacts with the threshing roller in each arc-shaped pressing plate. On the other hand, it reduces the gap between the lower end of the arc-shaped pressing plate and the threshing roller to prevent the corn cob from directly slipping out of the gap between the two and being placed in the next corn cob to be threshed. At the same time, the threshed corn cob core can fall from the gap between the lower end of the arc-shaped pressing plate and the threshing roller, completing the replacement of the old and new corn cobs. After the replacement is completed, the arc-shaped pressing plate presses the corn cob against the threshing roller assembly for threshing.

[0008] As a further configuration of the above scheme, a screening and discharging mechanism is arranged in the threshing box located below the threshing mechanism, the screening and discharging mechanism comprises an inclined sieve plate, a guide hopper is arranged below the sieve plate, a conveying seat extending out of the threshing box is arranged below the guide hopper, and a discharging conveyor belt is arranged in the conveying seat.

[0009] As a further configuration of the above scheme, a fixed plate is provided in the threshing box below the screen plate, a third spring is connected between the screen plate and the fixed plate, and a vibration motor is installed on the screen plate.

[0010] The present invention further provides a screening and discharging mechanism below the threshing mechanism, so that the corn kernels and corn cob cores can be separated by the sieve plate during the corn threshing process, so that the corn cob cores are discharged from the side end outlet of the threshing box, while the corn kernels are directionally sent out by the discharging conveyor belt, thereby achieving better classification effect.

[0011] As a further configuration of the above scheme, the lifting and conveying mechanism includes a vertical conveying box arranged on the side of the threshing box, belt rollers are arranged at the upper and lower ends of the vertical conveying box, and the end of one of the belt rollers is connected to a conveying motor, a conveying belt is arranged between the two belt rollers, a plurality of lifting plates are evenly arranged on the conveying belt, and a feeding hopper is arranged at the lower end of the vertical conveying box.

[0012] As a further configuration of the above scheme, the width of the lifting plate is set between 8 and 10 cm, and the length of the lifting plate is set between 50 and 150 cm.

[0013] The above is a specific design scheme for the lifting and conveying mechanism. By utilizing the conveying belt and the lifting plate, multiple corn cobs can be lifted upward in rows from the bottom of the vertical conveying box each time, and then centrifugally dropped onto the guide plate at the top of the vertical conveying box, so that the corn cobs can continue to roll in rows into the limited space formed by the arc baffle and the limit plate.

[0014] As a further configuration of the above scheme, the threshing roller assembly includes a threshing roller rotatably arranged in a threshing box, a plurality of threshing tooth plates are evenly arranged on the outer circumferential surface of the threshing roller, and a driving device is connected to the roller shaft of the threshing roller.

[0015] As a further configuration of the above scheme, a plurality of strip-shaped material leakage openings are spaced apart from each other at the lower end of the arc-shaped pressing plate horizontally aligned with the threshing roller.

[0016] As a further configuration of the above scheme, the spring free telescopic rod structure includes a sleeve connected to the end of the driving telescopic member, a movable connecting rod is inserted in the sleeve, and a first spring is arranged between the movable connecting rod and the sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The corn cob threshing processing device disclosed in the present invention can indirectly judge the threshing status of the corn cob through a pressure sensor during operation. The corn cob is discharged only when it is completely threshed and replaced with a new corn cob for further processing, so that the corn cob can be completely threshed, avoiding waste of corn raw materials.

[0018] The corn cob threshing processing device disclosed in the present invention can simultaneously introduce a plurality of corn cobs in rows into the space between each arc-shaped pressing plate and the threshing barrel for threshing processing, and after judging that the corresponding corn cobs are completely threshed, can independently control the corresponding arc-shaped pressing plate to rotate to switch the corn cob raw materials, so that the corn cobs in other threshing processes are not affected, and all corn cobs can be completely threshed. At the same time, the synchronous processing of multiple corn cobs also greatly improves the processing efficiency of the entire device; the structural design of the entire device is novel and ingenious, and while ensuring the complete threshing of the corn cobs, it improves the processing efficiency and avoids the mutual influence caused by the synchronous threshing process of multiple corn cobs, and has a good use effect.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 6 , and describes the application in detail with reference to embodiments. Example 1

[0023] Embodiment 1 discloses a complete threshing corn cob threshing processing device, refer to the attached Figure 1-6 , including a threshing box 1, on one side of which is provided a lifting and conveying mechanism 2 for conveying corn cobs in rows, a material guide plate 101 extending obliquely downward is provided at a position where the threshing box 1 is connected to the upper end of the lifting and conveying mechanism 2, and a threshing mechanism 3 is provided below the material guide plate 101.

[0024] The lifting and conveying mechanism 2 includes a vertical conveying box 201 fixedly connected to the side of the threshing box 1, and a belt roller 202 is rotatably arranged at both the upper and lower ends of the vertical conveying box 201, and a conveying motor 203 installed on the outer surface of the vertical conveying box 201 is connected to the end of one of the belt rollers 202. A conveying belt 204 is arranged between the two belt rollers 202, and a plurality of lifting plates 205 are evenly arranged on the outer surface of the conveying belt 204. In the specific design, the width of the lifting plate 205 is set between 8 and 10 cm, and the length of the lifting plate 205 is set between 50 and 150 cm, so that each lifting plate 205 can at least lift and convey no less than three corn cobs in rows. In addition, a feeding hopper 206 is arranged at the lower end of the side of the vertical conveying box 201 away from the threshing box 1, and a feeding port connected with the upper end of the guide plate 101 is opened at the upper end of the side close to the threshing box 1.

[0025] The lower end of the guide plate 101 is provided with an arc baffle 102 tangent thereto, and the threshing mechanism 3 includes a threshing roller 301 rotatably arranged at the center of the arc baffle 102, and a plurality of threshing tooth plates 302 are evenly arranged on the roller body of the threshing roller 301, and a driving device 303 installed on the outer surface of the threshing box 1 is connected to the roller shaft at one end of the threshing roller 301, and the specific driving device 303 is composed of a motor and a transmission belt, and the threshing roller 301 can rotate counterclockwise at a set speed under the power input of the motor. A first shaft 304 is fixedly arranged in the threshing box 1 on the opposite side of the guide plate 101, and a row of arc-shaped pressing plates 305 are rotatably arranged on the first shaft 304, so that each arc-shaped pressing plate 305 can squeeze a corn cob to make it close to one side of the threshing roller 301. The arc-shaped pressing plate 305 is designed to have a gradually larger spacing from the bottom to the top with respect to the threshing roller 301, and a plurality of strip-shaped material leakage openings 306 are provided at intervals at the lower end of the arc-shaped pressing plate 305 horizontally aligned with the threshing roller 301, so that the corn kernels that fall off can fall down through the strip-shaped material leakage openings 306. A limit plate 307 that is tilted downward and extends to the arc baffle 102 is fixedly connected to the arc-shaped pressing plate 305 above the strip-shaped material leakage openings 306, and a distance of about 2 cm is left between the limit plate 307 and the arc baffle 102, so that the corn cobs that roll down along the guide plate 101 can be limited to the space above the limit plate 307 and the arc baffle 102.

[0026] A second shaft rod 308 is also fixedly provided in the threshing box 1, and a driving telescopic member 309 corresponding to each arc-shaped pressing plate 305 is rotatably connected to the second shaft rod 308 in a row. The specific driving telescopic member 309 can be any one of an electric telescopic rod or a hydraulic telescopic rod. Then, a sleeve 310 is connected to the piston rod end of the driving telescopic rod 309, and a movable connecting rod 311 is inserted in the sleeve 310, and a first spring 312 is provided between the movable connecting rod 311 and the sleeve 310, so that the sleeve 310, the movable connecting rod 311 and the first spring 312 constitute a spring free telescopic rod structure, and the end of the movable connecting rod 311 is connected to the back side of the arc-shaped pressing plate 305, and the lower end of the arc-shaped pressing plate 305 can be pushed to one end of the threshing roller 301 through the action of the driving telescopic member 309 and the spring free telescopic rod structure.

[0027] At the same time, a strip plate 4 is fixedly arranged in the threshing box 1 on the back side of the arc-shaped pressing plate 305, and a row of pressure sensors 401 are fixedly installed on the side surface of the strip plate 4 facing the arc-shaped pressing plate 305, and each pressure sensor 401 is aligned with a arc-shaped pressing plate 305, and then a second spring 403 is connected between the pressure sensor 401 and the back side of the arc-shaped pressing plate 305. Finally, a row of pressure sensors 401 are also electrically connected to a controller 404 arranged on the outer side of the threshing box 1, and each driving telescopic member 309 is connected to the controller 404, so that it can be extended or shortened by the control of the controller 404.

[0028] During operation, the corn cob threshing device disclosed in the first embodiment is fed into the bottom of the vertical conveying box 201 through the feeding hopper 206, and then the corn cobs are lifted upward by the conveying belt 204 and the lifting plate 205. Due to the limitation of the size of the lifting plate 205, the corn cobs can only be lifted upward side by side in a straight line. When the corn cobs are lifted to the top of the vertical conveying box 201, they are turned over, and then thrown to the upper end of the guide plate 101 under the action of centrifugal force, and then roll along the guide plate 101 to between the arc baffle 102 and the limit plate 307.

[0029] Subsequently, the telescopic member 309 is controlled to be shortened. During this process, the arc-shaped pressing plate 305 will rotate around the first shaft 304 toward the side away from the threshing roller 301. At this time, the limit plate 307 connected to the arc-shaped pressing plate 305 rotates to the bottom of the arc baffle 102, so that the corn cobs supported above can fall through the gap. After the corn cobs fall, the telescopic member 309 is immediately controlled to be extended and reset. On the one hand, it hinders the corn cobs that continue to fall from the top, so that there is only one corn cob in each arc-shaped pressing plate 305 that interacts with the threshing roller 301. On the other hand, it reduces the gap between the lower end of the arc-shaped pressing plate 305 and the threshing roller 301 to prevent the corn cobs from directly slipping out of the gap between the two.

[0030] Then, due to the limiting effect of the arc-shaped pressing plate 305 and the effect of the threshing tooth plate 302 on the threshing roller 301 on the corn cob, the corn kernels on the corn cob are effectively removed until the corn kernels on the corn cob are completely threshed. When the corn kernels on the corn cob are completely threshed, the diameter of the corn cob core will be reduced to about 2 / 3 of the diameter, so under the squeezing effect of the threshing tooth plate 302 on the corn cob core, the stroke of the corn cob core applied to the second spring 403 and the compression of the second spring 403 is significantly reduced, and the corresponding pressure sensor 401 can detect this signal in the first time, and feedback to the controller 404, and then the controller 404 actively controls the corresponding driving telescopic member 309 to shorten it, and puts in the next corn cob to be threshed, and at the same time, the corn cob core that has been threshed can fall from the gap between the lower end of the arc-shaped pressing plate 305 and the threshing roller 301. In the whole threshing process, the threshing actions between each corn cob can be made independent, so as to avoid the corn cob being discharged from the threshing structure before it is completely threshed, thereby wasting raw material resources. Example 2

[0031] Example 2 discloses a corn cob threshing processing device that is further improved and designed based on the technical solution in Example 1, and the similarities between it and Example 1 are not described again.

[0032] Reference Figure 3 and attached Figure 4 In this embodiment 2, a screening discharging mechanism 5 is arranged in the threshing box 1 directly below the threshing mechanism 3. Specifically, the screening discharging mechanism 5 includes a sieve plate 501 arranged below the threshing roller 301 and the arc-shaped pressing plate 305. The sieve plate 501 is arranged to be tilted downward and extends out of the side of the threshing box 1. A fixing plate 502 is fixed in the threshing box 1 at both ends below the sieve plate 501, and then a third spring 503 is connected between the sieve plate 501 and the fixing plate 502. At the same time, a vibration motor 504 is also installed on the sieve plate 501.

[0033] A material guide hopper 505 is arranged directly below the sieve hole area on the sieve plate 501, and a conveying seat 506 extending out of the threshing box 1 is arranged directly below the discharge port of the material guide hopper 505, and then a discharge conveyor belt 507 for conveying corn kernels out of the threshing box 1 is arranged in the conveying seat 506.

[0034] In this embodiment 2, through the design of the above-mentioned screening and discharging mechanism 5, after the corn cob is completely threshed, the lower end drop port of the arc-shaped pressure plate 305 is opened, so that the corn cob core falls onto the screen plate 501, and then the corn cob core and corn kernels can move from top to bottom along the screen plate 501 under the high-frequency vibration of the vibration motor 504. During the movement, the corn kernels can pass through the sieve holes on the screen plate 501 into the guide hopper 505, and then are gathered by the guide hopper 505 and fall onto the discharging conveyor belt 507. Finally, the discharging conveyor belt 507 delivers the corn kernels out of the threshing box 1, and the corn cob core directly slides out of the threshing box 1 along the upper surface of the screen plate 501.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
