Description

Technical Field

[0001] The invention relates to the technical field of conveying agricultural machinery, in particular to a conveying device for processing fresh corn. Background Art

[0002] In order to ensure the freshness of corn, corn is usually stored in a granary. When corn is processed, fresh corn needs to be transported from the granary to the production line. Since the opening of the granary is usually at the top, it is usually necessary to use a conveying device to transport the corn from top to bottom.

[0003] In the existing patent literature, there is a patent with publication number CN 216685957 U, entitled "A buffered feeding trough for corn transportation". In actual application, the following problems are prone to occur:

[0004] 1. Since there is a certain height difference between the upper and lower adjacent feeding guide grooves, especially for fresh corn, the surface of the corn is easily damaged after it falls.

[0005] Second, because the cross section of the feeding guide is arc-shaped, the corn is concentrated in the middle of the feeding guide during the downward process, which is easy to cause blockage or pile at the falling node, such as Figure 1 As shown;

[0006] 3. Since the corn is transported directly from the granary, there will be some unqualified corn (such as small ones) in the granary, and the surface of the corn will also be sticky with stains (such as mud). When it passes through the discharge guide chute, the corn cannot be screened and cleaned beforehand, resulting in too much amount to be processed when it reaches the production line later, which is easy to cause processing difficulties. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a conveying device for processing fresh corn, the buffer zone of the conveying device can reduce the impact force of the corn when it falls to prevent damage to the corn surface; the cleaning screening area of ​​the conveying device can not only clean the stains (mud, etc.) on the surface of the corn, but also screen out unqualified (small) corn; the vibrating plate in the vibration zone of the conveying device can reciprocately vibrate the corn that is about to fall, which can avoid the phenomenon of corn piling or blocking at the falling point.

[0008] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0009] A conveying device for processing fresh corn comprises a conveying box body, a hollow conveying cavity is provided in the conveying box body, and an inlet and an outlet are respectively provided above and below the hollow conveying cavity;

[0010] Multiple buffer-type screening-vibration integrated conveying inclined ladders are installed in the hollow conveying cavity from top to bottom. Each buffer-type screening-vibration integrated conveying inclined ladder is inclined and arranged in an array in a "staircase shape";

[0011] The buffer type cleaning and vibrating integrated conveying inclined ladder has a buffer zone, a cleaning screening zone and a vibrating zone from top to bottom along its inclined surface. The common lower part of the buffer zone, the cleaning screening zone and the vibrating zone is the miscellaneous material conveying zone. The buffer zone, the cleaning screening zone, the vibrating zone and the miscellaneous material conveying zone are all located on two sets of inclined ladder frames fixed on the side wall of the hollow conveying cavity.

[0012] The buffer zone includes a buffer air cushion fixedly installed between two sets of inclined ladder frames;

[0013] The cleaning screening area includes multiple groups of cleaning screening rollers rotatably installed between two groups of inclined ladder frames. All cleaning screening rollers are arranged in a linear array along the length direction of the inclined ladder frames, and there is a spacing between each two adjacent groups of cleaning screening rollers. After being driven, all cleaning screening rollers can rotate upward along the inclined surface of the inclined ladder frames.

[0014] The vibration zone includes a vibration material plate rotatably mounted between two groups of inclined ladder frames, a vibration material drum rotatably mounted on one group of inclined ladder frames is arranged below the vibration material plate, the vibration material plate is supported by the vibration material drum, and at least one eccentric protrusion extending in the axial direction of the vibration material drum is fixed on the surface of the vibration material drum;

[0015] The miscellaneous material conveying area includes two sets of driving rollers, which are connected to the conveyor belts. The conveyor belts, the buffer air cushions, the multiple sets of cleaning screening rollers and the vibrating plates are parallel to each other. After being driven, the driving rollers can rotate upward along the inclined surface of the inclined ladder frame.

[0016] A three-in-one driving mechanism is installed on any set of inclined ladder frames, and the three-in-one driving mechanism drives the cleaning screening roller, the vibrating drum and the driving roller to rotate synchronously at the same time.

[0017] By adopting the above scheme, the conveying device is used for conveying fresh corn from the granary to the production line; wherein the buffer air cushion in the buffer zone can reduce the impact force of the corn when it falls to prevent damage to the corn surface; wherein the cleaning screening roller in the cleaning screening area can not only clean the stains (mud, etc.) on the surface of the corn, but also screen out unqualified (fine) corn; wherein the vibrating plate in the vibration zone can reciprocately vibrate the corn that is about to fall, which can avoid the phenomenon of corn piling or blocking at the falling point; wherein the conveyor belt in the miscellaneous material conveying area can convey the fallen unqualified (fine, etc.) corn and stains (mud, etc.).

[0018] As a preferred embodiment of a conveying device for processing fresh corn, the interior of the buffer air cushion is filled with an inert gas, such as nitrogen, etc., and the gas pressure of the inert gas is 0.8-0.9 times the external standard atmospheric pressure.

[0019] By adopting the above scheme, in order to prevent the corn from bouncing to a large height after falling into the buffer air cushion, the gas in the buffer air cushion is adjusted to be lower than the external standard atmospheric pressure. The corn will not bounce to a large height after falling into the buffer air cushion, thereby avoiding damage to the corn. The inert gas (nitrogen) in the buffer air cushion is more stable and is less affected by temperature conditions, and will not cause too large fluctuations in the air pressure value.

[0020] As a preferred embodiment of a conveying device for processing fresh corn, the surface of the cleaning screening roller is fully covered with cleaning bristles, the cleaning bristles are soft bristles, and the surface of the cleaning bristles is smooth.

[0021] By adopting the above scheme, in order to clean the stains on the surface of corn, when the corn rolls down the inclined surface, the cleaning screening roller is driven to rotate upward, and the soft cleaning bristles can create resistance to the rolling corn, which can not only comprehensively clean the surface of the corn, but also slow down the speed of the corn rolling down, thereby protecting the corn from damage as much as possible.

[0022] As a preferred embodiment of a conveying device for processing fresh corn, a plurality of hollow grooves are provided through the body of the vibrating plate.

[0023] In order to ensure that the dirt (mud, etc.) can fall on the vibrating plate, a plurality of hollow grooves are provided, and the dirt can fall from the hollow grooves onto the conveyor belt.

[0024] As a preferred embodiment of the conveying device for processing fresh corn, the surface of the vibrating drum other than the eccentric protrusion is covered with a rubber pad.

[0025] By adopting the above scheme, the rotating vibrating drum can press against the vibrating plate and turn over at a certain angle through the eccentric protrusion, and then the array plate falls down under the action of gravity, thereby realizing reciprocating vibration. However, in order to reduce the noise during vibration, a rubber pad is covered on the surface of the vibrating drum, and the noise of the vibrating plate when contacting the vibrating drum will be reduced.

[0026] As a preferred embodiment of a conveying device for processing fresh corn, the surface of the conveyor belt has a plurality of convex stops distributed in a linear array along its conveying direction.

[0027] With the above scheme, since the conveyor belt is set at an angle, in order to prevent unqualified (small) corn from falling onto the conveyor belt and rolling down, multiple convex blocks are provided. Through the blocking of the convex blocks, the unqualified (small, etc.) corn and stains (mud, etc.) can be transported out under the action of the friction force of the conveyor belt.

[0028] As a preferred embodiment of a conveying device for processing fresh corn, the three-in-one driving mechanism includes a driving motor fixedly mounted on the outer wall of the conveying box; it also includes a double transmission gear set 1 concentrically connected to one end of each group of cleaning screening rollers, and each two adjacent double transmission gear sets 1 are connected through a transmission chain 1; it also includes a single transmission gear concentrically connected to one end of a vibrating drum, and the single transmission gear is connected to any double transmission gear set 1 through a transmission chain 2; it also includes a double transmission gear set 2 concentrically connected to one end of each group of driving rollers, the two groups of double transmission gear sets 2 are connected through a transmission chain 3, and any double transmission gear set 2 is connected to the double transmission gear set 1 through a transmission chain 4;

[0029] Among them, the diameters of all gears on the dual transmission gear set 1, the single transmission gear and the dual transmission gear set 2 are the same.

[0030] By adopting the above scheme, in order to realize the synchronous driving of the cleaning screening roller, the vibrating drum and the driving roller, only one driving motor is used, and through the transmission of multiple gear sets and chains, the synchronous rotation of the cleaning screening roller, the vibrating drum and the driving roller can be realized.

[0031] As a preferred embodiment of a conveying device for processing fresh corn, a miscellaneous material conveying chamber distributed on both sides of the hollow conveying chamber and not connected to the hollow conveying chamber is provided in the conveying box body; a miscellaneous material inlet is provided between the hollow conveying chamber and the miscellaneous material conveying chamber at the location of the conveyor belt, and a miscellaneous material outlet is provided at the bottom of the miscellaneous material conveying chamber; wherein a material guide plate located in the hollow conveying chamber is provided at the bottom of the location of the miscellaneous material inlet, and the material guide plate is gradually inclined and lowered from the hollow conveying chamber to the location of the miscellaneous material conveying chamber.

[0032] By adopting the above scheme, in order to facilitate the transportation of unqualified (small, etc.) corn and stained (mud, etc.) debris, the debris first falls onto the guide plate after being transported on the conveyor belt, then enters the debris conveying chamber through the debris inlet, and is finally discharged from the debris outlet.

[0033] After adopting the above technical solution, the beneficial effects of the present invention are:

[0034] 1. The conveying device is used for conveying fresh corn from the granary to the production line; the buffer air cushion in the buffer zone can reduce the impact force of the corn when it falls to prevent damage to the corn surface; the cleaning screening roller in the cleaning screening area can not only clean the stains (mud, etc.) on the surface of the corn, but also screen out unqualified (fine) corn; the vibrating plate in the vibration zone can reciprocate the corn that is about to fall, which can avoid the phenomenon of corn piling or blocking at the falling point; the conveyor belt in the miscellaneous material conveying area can convey the unqualified (fine, etc.) corn and stains (mud, etc.) that fall;

[0035] 2. In order to prevent the corn from bouncing up to a large height after falling into the cushion, the gas in the cushion is adjusted to a lower level than the standard atmospheric pressure outside. The corn will not bounce up to a large height after falling into the cushion, thus avoiding damage to the corn. The inert gas (nitrogen) in the cushion is more stable and less affected by temperature conditions, so it will not cause too much fluctuation in the air pressure value.

[0036] 3. In order to clean the stains on the surface of corn, when the corn rolls down the slope, the cleaning screening roller is driven to rotate upward, and the soft cleaning bristles can create resistance to the rolling corn, which can not only clean the surface of the corn comprehensively, but also slow down the speed of the corn rolling down, so as to protect the corn from damage as much as possible; because there is a certain distance between the two adjacent cleaning screening rollers, the corresponding small unqualified corn will fall directly from the distance to the conveyor belt;

[0037] 4. In order to realize reciprocating vibration, the rotating vibration drum can touch the vibration plate and turn up a certain angle through the eccentric protrusion, and then the array plate falls down under the action of gravity to realize reciprocating vibration. However, in order to reduce the noise during vibration, the surface of the vibration drum is covered with a rubber pad, and the noise of the vibration plate when contacting the vibration drum will be reduced;

[0038] 5. As the conveyor belt is tilted, in order to prevent unqualified (small) corn from falling onto the conveyor belt and rolling down, multiple convex blocks are set. Through the blocking of the convex blocks, the unqualified (small, etc.) corn and stains (mud, etc.) can be transported out under the action of the friction of the conveyor belt;

[0039] 6. In order to realize the synchronous drive of the cleaning screening roller, the vibrating drum and the driving roller, only one driving motor is used. Through the transmission of multiple gear sets and chains, the cleaning screening roller, the vibrating drum and the driving roller can be rotated synchronously, which has lower investment cost and less energy consumption;

[0040] 7. In order to facilitate the transportation of unqualified (small, etc.) corn and dirt (mud, etc.) debris, the debris falls onto the guide plate after being transported on the conveyor belt, then enters the debris conveying chamber through the debris inlet, and is finally discharged from the debris outlet.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] like Figures 2 to 7 , Figures 11 to 13 As shown, a conveying device for processing fresh corn includes a conveying box 1, a hollow conveying chamber 2 is provided in the conveying box 1, and an inlet and an outlet are respectively provided above and below the hollow conveying chamber 2;

[0059] A plurality of buffer-type cleaning screen 3-vibration integrated conveying inclined ladders are installed in the hollow conveying chamber 2 from top to bottom, and each buffer-type cleaning screen 3-vibration integrated conveying inclined ladder is inclined and arranged in an array in a "staircase shape";

[0060] The buffer type cleaning and screening 3-vibration integrated conveying inclined ladder is divided into a buffer zone, a cleaning screening zone and a vibration zone from top to bottom along its inclined surface. The common lower part of the buffer zone, the cleaning screening zone and the vibration zone is the miscellaneous material conveying zone. The buffer zone, the cleaning screening zone, the vibration zone and the miscellaneous material conveying zone are all located on two sets of inclined ladder frames 4 fixed on the side walls of the hollow conveying chamber 2;

[0061] The buffer zone includes a buffer air cushion 5 fixedly installed between two sets of inclined ladder frames 4;

[0062] The cleaning screening area includes multiple groups of cleaning screening rollers 6 rotatably installed between two groups of inclined ladder frames 4. All cleaning screening rollers 6 are arranged in a linear array along the length direction of the inclined ladder frames 4, and a spacing is provided between each two adjacent groups of cleaning screening rollers 6. After being driven, all cleaning screening rollers 6 can rotate upward along the inclined surface of the inclined ladder frames 4.

[0063] The vibration zone includes a vibration material plate 7 rotatably mounted between two groups of inclined ladder frames 4, and a vibration material drum 8 rotatably mounted on one group of inclined ladder frames 4 is arranged below the vibration material plate 7. The vibration material plate 7 is supported by the vibration material drum 8, and at least one eccentric protrusion 10 extending in the axial direction of the vibration material drum 8 is fixed on the surface of the vibration material drum 8;

[0064] The miscellaneous material conveying area includes two sets of driving rollers, and the two sets of driving rollers are connected with a conveyor belt 9. The conveyor belt 9, the buffer air cushion 5, the multiple sets of cleaning screening rollers 6 and the vibrating plate 7 are parallel to each other. After being driven, the driving rollers can rotate upward along the inclined surface of the inclined ladder frame 4;

[0065] A three-in-one driving mechanism 13 is installed on any group of inclined ladder frames 4, and the three-in-one driving mechanism 13 drives the cleaning screening roller 6, the vibrating drum 8 and the driving roller to rotate synchronously at the same time.

[0066] The conveying device is used for conveying fresh corn from a granary to a production line; the buffer air cushion 5 in the buffer zone can mitigate the impact force of the corn when it falls to prevent damage to the corn surface; the cleaning screening roller 6 in the cleaning screening zone can not only clean the stains (mud, etc.) on the surface of the corn, but also screen out unqualified (fine) corn; the vibrating plate 7 in the vibration zone can reciprocate the corn that is about to fall, so as to avoid the phenomenon of corn piling or blocking at the falling point; the conveyor belt 9 in the miscellaneous material conveying zone can convey the fallen unqualified (fine, etc.) corn and stains (mud, etc.).

[0067] like Figures 5 to 8 , Fig.13 As shown, the interior of the buffer air cushion 5 is filled with an inert gas, such as nitrogen, etc., and the gas pressure of the inert gas is 0.8-0.9 times the external standard atmospheric pressure. In order to prevent the corn from bouncing up to a large height after falling to the buffer air cushion 5, the gas in the buffer air cushion 5 is adjusted to be lower than the external standard atmospheric pressure, so that the corn will not bounce up to a high height after falling to the buffer air cushion 5, thereby avoiding damage to the corn; and the inert gas (nitrogen) in the buffer air cushion 5 is more stable, and is less affected by temperature conditions, and will not cause too large fluctuations in the air pressure value.

[0068] like Figures 5 to 8 , Fig.13 As shown, the surface of the cleaning screening roller 6 is fully covered with cleaning bristles, which are soft bristles and have a smooth surface. In order to clean the stains on the surface of the corn, when the corn rolls down the inclined surface, the cleaning screening roller 6 is driven to rotate upward, and the soft cleaning bristles can create resistance to the rolling corn, which can not only clean the surface of the corn comprehensively, but also slow down the speed of the corn rolling down, thereby protecting the corn from damage as much as possible; because there is a certain distance between the two adjacent cleaning screening rollers 6, the corresponding small unqualified corn will directly fall from the distance to the conveyor belt 9.

[0069] like Figures 5 to 8 , Fig.13 As shown, there are multiple hollow grooves on the plate body of the vibration material plate 7. In order to ensure that stains (mud, etc.) can fall on the vibration material plate 7, multiple hollow grooves are provided, and the stains can fall on the conveyor belt 9 from the hollow grooves.

[0070] like Fig.11 As shown, the vibrating drum 8 is also covered with a rubber pad 11 on the surface other than the eccentric protrusion 10. In order to achieve reciprocating vibration, the rotating vibrating drum 8 can resist the vibrating plate 7 and turn up to a certain angle through the eccentric protrusion 10, and then the array plate falls down under the action of gravity, thereby achieving reciprocating vibration. However, in order to reduce the noise during vibration, the rubber pad 11 is covered on the surface of the vibrating drum 8, and the noise of the vibrating plate 7 when contacting the vibrating drum 8 will be reduced.

[0071] like Fig.12 As shown, the surface of the conveyor belt 9 has a plurality of convex stops 12 distributed in a linear array along the conveying direction. Since the conveyor belt 9 is arranged at an angle, in order to prevent unqualified (small) corns from falling onto the conveyor belt 9 and rolling down, a plurality of convex stops 12 are arranged. Through the blocking of the convex stops 12, the unqualified (small, etc.) corns and stains (mud, etc.) can be conveyed out under the action of the friction force of the conveyor belt 9.

[0072] like Figures 9 and 10As shown, the three-in-one driving mechanism 13 includes a driving motor 14 fixedly mounted on the outer wall of the conveying box body 1; it also includes a double transmission gear set 15 concentrically connected to one end of each group of cleaning screening rollers 6, and each two adjacent double transmission gear sets 15 are connected through a transmission chain 16; it also includes a single transmission gear 17 concentrically connected to one end of the vibrating drum 8, and the single transmission gear 17 is connected to any double transmission gear set 15 through a transmission chain 2 18; it also includes a double transmission gear set 2 19 concentrically connected to one end of each group of driving rollers, the two groups of double transmission gear sets 2 19 are connected through a transmission chain 3 20, and any double transmission gear set 2 19 is connected to the double transmission gear set 15 through a transmission chain 4 21; wherein, the diameters of all gears on the double transmission gear set 15, the single transmission gear 17 and the double transmission gear set 2 19 are the same. In order to realize the synchronous driving of the cleaning screening roller 6, the vibrating drum 8 and the driving roller, only one driving motor 14 is used. Through the transmission of multiple gear sets and chains, the synchronous rotation of the cleaning screening roller 6, the vibrating drum 8 and the driving roller can be realized, which has lower investment cost and less energy consumption.

[0073] like Fig.14 As shown, the conveying box body 1 is also provided with miscellaneous material conveying chambers 22 distributed on both sides of the hollow conveying chamber 2 and not connected to the hollow conveying chamber 2; miscellaneous material inlets 23 are provided between the hollow conveying chamber 2 and the miscellaneous material conveying chamber 22 at the location of the conveyor belt 9, and a miscellaneous material outlet 24 is provided at the bottom of the miscellaneous material conveying chamber 22; wherein, a guide plate 25 located in the hollow conveying chamber 2 is provided at the bottom where the miscellaneous material inlet 23 is located, and the guide plate 25 is gradually inclined and lowered from the hollow conveying chamber 2 to the location of the miscellaneous material conveying chamber 22. In order to facilitate the conveying of unqualified (small, etc.) corn and stained (mud, etc.) miscellaneous materials, the miscellaneous materials first fall onto the guide plate 25 after being conveyed on the conveyor belt 9, and then enter the miscellaneous material conveying chamber 22 through the miscellaneous material inlet 23, and finally are discharged from the miscellaneous material outlet 24.

[0074] Working principle of the present invention:

[0075] When in use, the top of the conveying box 1 is installed on the door above the granary, and the bottom of the conveying box 1 corresponds to the conveyor belt of the production line, so as to transport the fresh corn in the granary to the production line for processing.

[0076] During transportation, the fresh corn is transported through multiple buffer-type cleaning and 3-vibration integrated conveying inclined ladders in a "staircase" shape. The buffer-type cleaning and 3-vibration integrated conveying inclined ladders can realize buffering, cleaning, vibration and sundry material conveying of the fresh corn.

[0077] When passing through the buffer zone of the buffer cleaning and screening 3-vibration integrated conveying inclined ladder, in order to prevent the surface of the corn from being damaged when it falls, a buffer air cushion 5 is set at the corn falling place, and the gas in the buffer air cushion 5 is adjusted to be lower than the external standard atmospheric pressure. After the corn falls to the buffer air cushion 5, there will be no high bounce, thereby avoiding damage to the corn; and the inert gas (nitrogen) in the buffer air cushion 5 has a high stability, is less affected by temperature conditions, and will not cause too much fluctuation in the air pressure value; it can slow down the impact force of the corn when it falls to prevent damage to the corn surface, such as Fig.13 shown.

[0078] When passing through the cleaning screening area of ​​the buffer cleaning screen 3-vibration integrated conveying inclined ladder, in order to clean the stains on the surface of the corn, when the corn rolls down along the inclined surface, the cleaning screening roller 6 is driven to rotate upward by the three-in-one driving mechanism 13, and the soft cleaning bristles can create resistance to the rolling corn, which can not only comprehensively clean the surface of the corn, but also slow down the speed of the corn rolling down, so as to protect the corn from damage as much as possible; because there is a certain distance between the two adjacent cleaning screening rollers 6, the corresponding small unqualified corn will fall directly from the distance to the conveyor belt 9; it can not only clean the stains (mud, etc.) on the surface of the corn, but also screen out the unqualified (small) corn, such as Fig.13 shown.

[0079] When passing through the vibration zone of the buffer type cleaning screen 3-vibration integrated conveying inclined ladder, in order to realize reciprocating vibration, the vibration drum 8 is driven to rotate by the three-in-one driving mechanism 13, and the rotating vibration drum 8 can resist the vibration plate 7 and turn up a certain angle through the eccentric protrusion 10, and then the array plate falls again under the action of gravity, so as to realize reciprocating vibration; it can reciprocately vibrate the corn that is about to fall, and can avoid the phenomenon of corn piling or blocking at the falling point, such as Fig.13 shown.

[0080] In order to facilitate the conveying of unqualified (small, etc.) corn and dirt (mud, etc.) debris, a debris conveying area of ​​a buffer-type cleaning screen 3-vibration integrated conveying inclined ladder is set, and the conveyor belt 9 is driven downward by the three-in-one driving mechanism 13. At this time, the debris falls onto the conveyor belt 9 and is transported upward with the conveyor belt 9. After that, the debris first falls onto the guide plate 25, and then enters the debris conveying cavity 22 through the debris inlet 23, and is finally discharged from the debris outlet 24. Fig.13 and Fig.14 shown.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
