A grain drying equipment for reducing the breakage rate

Abstract

The present invention discloses a grain drying device for reducing the breakage rate. Grains are evenly scraped into a quantitative grain storage port and leveled by a scraping flat plate frame. An intermittent opening and closing plate is arranged to intermittently open and close the quantitative grain storage port, so that the grains are fed onto the drying assembly below in an intermittent manner for drying. The dispersed grains will vertically fall under the limitation and block of the inner arc section where adjacent hot angle-shaped boxes are close to each other, so that there is a gap between the air permeable part on the inner arc section and the grain falling path, facilitating the hot air to pass through the air permeable part and the air vent section of the material bearing plate to dry the grains on the side and lower sides. The extrusion thrust received by the collision block is transmitted to the inner arc section for vibration, and the cooperation of the pushed arc block and the torsion spring plate enables the material bearing plate to vibrate, which can make the grains falling above the material bearing plate jump under the action of the vibration force, and fall into the lower hot angle-shaped box through the gap between adjacent material bearing plates for circulation, prolonging the residence time of the grains in the hot angle-shaped box.

Description

Technical Field

[0001] The present invention belongs to the technical field of grain drying, and particularly relates to a grain drying device for reducing the breakage rate. Background Art

[0002] The internal angled box of the tower-type grain drying device is an important component for distributing hot air or collecting and discharging moisture. When the angled box works, hot air enters the inside of the inlet angled box from the end of the inlet angled box and then is discharged from the bottom of the angled box. The hot air discharged from the bottom of the angled box contacts and exchanges heat with the grains in the lower position for drying. During the daily drying process, the grains are intermittently transferred from the storage bin to the drying layer and then lifted back to the storage bin in turn. After multiple cycles, the grains collide and rub against the equipment greatly, causing serious damage to the grain seeds. Therefore, how to improve the drying effect of the drying component so that it can dry the grains sufficiently during a single cycle of the grains, thereby avoiding secondary damage to the grains during the cyclic lifting and drying process, is the direction that needs to be improved;

[0003] For example, the Chinese patent with the publication number CN113108585B discloses a grain drying device with automatic cyclic drying. The drying device includes a housing, an inclined plate and a throwing disc. An inclined plate is installed at the top inside the housing near the elevator side, and a throwing disc is installed at the top inside the housing below the inclined plate. The drying device further includes a dispersion device, a grain pusher device and a vibration device. The dispersion device is evenly installed in the middle of the housing. The drying component is installed inside the housing below the dispersion device. The grain pusher device is evenly installed at the lower part of the housing below the drying component. The vibration device is hinged to the bottom of the housing; the drying component includes a support frame and a mesh plate. The mesh plates are evenly installed at the top of the support frame. The outside of the housing is connected to a hot air blower at one side of the drying component. Therefore, hot air enters from one side of the drying component, thereby quickly drying the grains passing between the mesh plates; A cold air inlet is further provided at the lower part of the drying component, and cold air is introduced into the cold air inlet to cool the grains dried by the drying component.

[0004] Another example is the Chinese patent with the publication number CN109373740A, which discloses an angled box of a grain drying tower. The angled box of the grain drying tower is a long and narrow trough-shaped body with open ends and bottom made of steel plates. The trough-shaped body includes a ∧-shaped trough top and two parallel vertical trough walls. The distance between the two vertical trough walls is less than the opening width at the bottom of the ∧-shaped trough top. A horizontal trough eaves is provided at the lower edge on each side of the ∧-shaped trough top and is connected to the upper edge of the vertical trough wall on that side. The ∧-shaped trough top, the two vertical trough walls and the two horizontal trough eaves are connected together to jointly form an angled box of the grain drying tower with a hollow arrow-shaped cross section.

[0005] However, the above solutions have the following deficiencies: In the patent with the publication number CN113108585B, a drying component composed of a support frame and a mesh plate is adopted, and hot air is discharged by a hot air blower to dry the passing grain seeds, and the feeding is carried out through a grain feeding device. However, the grain between the mesh plates is not dried intermittently. The continuous falling of grain above will cause the grain between the mesh plates to accumulate on each other, which is not conducive to the uniform drying of the grain. Therefore, the patent with the publication number CN109373740A can disperse the grain passing through the angled box through the improvement of the angled box, so that the grain located in the middle and lower parts on both sides of the angled box can be heat-exchanged and dried. However, when the grain falls from the top of the angled box, it will slide obliquely along the hypotenuse. The obliquely sliding grain will block the middle section of the side part of the adjacent angled box on the adjacent side, resulting in the obstruction of the hot air flow in the middle parts on both sides of the angled box. At the same time, the residence time of the grain in the gap between the angled boxes is short, and the drying efficiency is lacking. How to further improve the drying component composed of angled boxes, on the basis of intermittent drying of the grain, extend the drying time of the grain between the angled boxes, and at the same time enable the middle parts on both sides of the angled box not to be blocked by the obliquely sliding grain to cause hot air obstruction is the problem to be solved at present. Summary of the Invention

[0006] The purpose of the present invention is to provide a grain seed drying equipment with a reduced breakage rate to solve the problems existing in the above background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A grain seed drying equipment with a reduced breakage rate includes a tower dryer housing, a uniform distribution plate, a drying component, and a discharge valve part arranged in sequence from top to bottom. The drying component is composed of hot angled boxes arranged in a vertically staggered manner, and a hot air inlet pipe and a cold air inlet are sequentially arranged on the upper and lower parts of the drying component. The uniform distribution plate is provided with a quantitative grain storage port and is arranged opposite to the top of the hot angled box below, and an intermittent opening and closing plate is arranged below the uniform distribution plate and is used to adjust the opening and closing of the discharge end of the quantitative grain storage port;

[0008] The upper and lower parts of the hot angled box are respectively an angled section and an inner arc section, and the lower part of the inner arc section is a breathable part. The air inlet port of the hot angled box is connected to the hot air inlet pipe, and a rotating shaft is rotatably arranged at the exhaust end of the hot air inlet pipe through a bearing frame and extends into the hot angled box. An air-facing rotating paddle is fixedly sleeved on the rotating shaft, and a wind guiding push plate is circumferentially arranged on the extending section of the rotating shaft. The wind guiding push plate is used to introduce the inflowing hot air into the inner arc sections on both sides of the hot angled box. At the same time, a bearing plate is resetably and rotatably arranged at the bottom end of the inner arc section. The bearing plates between adjacent hot angled boxes have a gap for the uniform falling of grain. At the same time, the hot air discharged from the hot air inlet pipe will drive the air-facing rotating paddle, the rotating shaft, and the wind guiding push plate to rotate in sequence, and the rotation of the wind guiding push plate can drive the deflection and vibration of the inner arc section and the bearing plate in sequence.

[0009] Preferably, a scraping flat plate frame is arranged on the upper surface of the equalizing plate and is horizontally and transversely pushed. The feeding end of the tower dryer housing discharges a fixed amount of grain into the fixed - quantity grain storage port on the equalizing plate. At the same time, the scraping flat plate frame levels the upper end surface of the fixed - quantity grain storage port.

[0010] Preferably, the intermittent opening and closing plate can be horizontally and fixedly pushed. The upper end surface of the intermittent opening and closing plate is provided with a discharge port that can cooperate with the discharge end of the fixed - quantity grain storage port. When the discharge end of the fixed - quantity grain storage port is communicated with the discharge port, the adjacent angled - section of the hot angled box is arranged directly below the corresponding discharge port.

[0011] Preferably, the adjacent inner arc sections of the hot angled boxes form a V - shaped structure. At the same time, a gear reducer is fixedly arranged on the inner wall of the hot air inlet pipe. The driving end of the gear reducer is connected to the rotating shaft of the windward rotating paddle, so that the rotating speed of the rotating shaft section extending into the hot angled box is less than the rotating speed of the rotating shaft section connected to the windward rotating paddle.

[0012] Preferably, collision blocks are arranged on the inner side wall of the inner arc section. The air - guiding push plate has an outer bevel structure on both sides, and a deformable arc elastic sheet is arranged at the outer end of the air - guiding push plate. When the air - guiding push plate rotates, the inner arc section deflects and vibrates through the contact between the deformable arc elastic sheet and the collision blocks.

[0013] Preferably, a torsion spring plate is arranged at the bottom end of the inner arc section. The torsion spring on the torsion spring plate is fixedly arranged with the turning end of the material - receiving plate. An air - venting section is preset on the material - receiving plate. And a pushed arc block vertically slides through the torsion spring plate. The bottom end of the pushed arc block is movably arranged with the material - receiving plate. When the air - guiding push plate rotates, it will drive the deformable arc elastic sheet to push the pushed arc block downward. And the acting forces of the pushed arc block and the torsion spring plate on the material - receiving plate are opposite, which can make the material - receiving plate deflect and vibrate. Thus, the grain above the material - receiving plate between adjacent hot angled boxes is vibrated and thrown upward and evenly dried by hot air.

[0014] Preferably, a first driving and pushing member and a second driving and pushing member are respectively arranged on the side wall of the tower dryer housing. And the first driving and pushing member and the second driving and pushing member are composed of any one of a screw motor, an electric telescopic rod, and a linear slide rail. The first driving and pushing member and the second driving and pushing member are respectively used for the pushing movement of the equalizing plate and the intermittent opening and closing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The grain is evenly scraped into the fixed - quantity grain storage port and leveled by the scraping flat plate frame. The intermittent opening and closing of the intermittent opening and closing plate for the fixed - quantity grain storage port enables the grain to be intermittently fed onto the lower drying component for drying;

[0017] 2. The scattered grains will fall vertically under the restriction and block of the inner arc section where adjacent hot angular boxes are close to each other, creating a gap between the air-permeable part on the inner arc section and the grain falling path, facilitating the hot air to pass through the air-permeable part and the air vent section of the material-bearing plate to dry the grains on the side and below. The extrusion thrust received by the collision block will be transmitted to the inner arc section to cause vibration, and the cooperation of the pushed arc block and the torsion spring plate can make the material-bearing plate vibrate. As a result, the grains falling above the material-bearing plate can bounce under the action of the vibration force and fall through the gap between adjacent material-bearing plates into the lower hot angular box for circulation, extending the residence time of the grains in the hot angular box.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figures 1-8 , the present invention provides a technical solution:

[0029] Embodiment 1:

[0030] A grain drying device for reducing the breakage rate, including a tower dryer housing 1, an equalizing plate 2, a drying component 101, and a discharge valve part 102 arranged in sequence from top to bottom. The discharge valve part 102 is a discharge butterfly valve used in the existing tower dryer housing 1, which will not be elaborated. The drying component 101 is composed of heat angle boxes 201 arranged in a vertically staggered manner. A hot air inlet pipe 301 and a cold air inlet are sequentially arranged on the upper and lower parts of the drying component 101. The air inlet end of the hot air inlet pipe 301 is provided with a heat source by an external heat pump. The equalizing plate 2 is provided with a quantitative grain storage port 3 and is arranged opposite to the top of the heat angle box 201 below. An intermittent opening and closing plate 4 is arranged below the equalizing plate 2 and is used to adjust the opening and closing of the discharge end of the quantitative grain storage port 3.

[0031] The upper and lower parts of the heat angle box 201 are respectively an angular section and an inner arc section 5. The lower part of the inner arc section 5 is a ventilation part 6. The setting of the inner arc section 5 avoids the falling grains on the hypotenuse of the heat angle box 201 from covering the ventilation part 6, enabling hot air to pass through the ventilation part 6 and make thermal contact with the falling grains. The air inlet port of the heat angle box 201 is communicated with the hot air inlet pipe 301. A rotating shaft 7 is rotatably arranged at the exhaust end of the hot air inlet pipe 301 through a bearing frame and extends into the heat angle box 201. An air-facing rotating blade 8 is fixedly sleeved on the rotating shaft 7. A wind guiding push plate 9 is circumferentially arranged on the extended section of the rotating shaft 7. The wind guiding push plate 9 is used to introduce the inflowing hot air into the inner arc sections 5 on both sides of the heat angle box 201. At the same time, a bearing plate 10 is resetably and turnably arranged at the bottom end of the inner arc section 5. When the adjacent bearing plates 10 between the heat angle boxes 201 are turned, the gap between them will become larger, facilitating the grains falling above the bearing plate 10 to fall to the heat angle box 201 arranged in a staggered manner below for dispersed drying. There is a gap for the grains to fall evenly between the adjacent bearing plates 10 between the heat angle boxes 201. At the same time, the hot air discharged from the hot air inlet pipe 301 will drive the air-facing rotating blade 8, the rotating shaft 7, and the wind guiding push plate 9 to rotate in sequence, and the rotation of the wind guiding push plate 9 can drive the deflection vibration of the inner arc section 5 and the bearing plate 10 in sequence.

[0032] Embodiment 2:

[0033] On the basis of the first embodiment, it is further described that a scraping plate frame 11 is horizontally and transversely pushed on the upper surface of the equalizing plate 2. The scraping plate frame 11 is composed of a scraping plate and a sliding frame. A silicone rubber sheet is bonded to the bottom end surface of the scraping plate, and the silicone rubber sheet is in close contact with the upper surface of the equalizing plate 2. A main sliding hole is correspondingly provided on the outer side wall of the tower dryer housing 1. The sliding frame slides through the main sliding hole. Through the horizontal reciprocating sliding of the sliding frame on the main sliding hole, the scraping plate evenly scrapes the grain accumulated on the upper surface of the equalizing plate 2 into the quantitative grain storage port 3. The feeding end of the tower dryer housing 1 discharges a fixed amount of grain into the quantitative grain storage port 3 on the equalizing plate 2, and at the same time, the scraping plate frame 11 levels the upper end surface of the quantitative grain storage port 3;

[0034] The intermittent opening and closing plate 4 can be horizontally and fixedly displaced. An outlet 12 that can cooperate with the discharge end of the quantitative grain storage port 3 is arranged on the upper end surface of the intermittent opening and closing plate 4. When the discharge end of the quantitative grain storage port 3 is communicated with the outlet 12, the angular segments of the adjacent heat angle-shaped boxes 201 are arranged directly below the corresponding outlet 12.

[0035] Embodiment Three:

[0036] On the basis of the first embodiment, it is further described that the adjacent inner arc segments 5 of the heat angle-shaped boxes 201 form an eight-shaped structure. At the same time, a gear reduction member 13 is fixedly arranged on the inner wall of the hot air inlet pipe 301. The gear reduction member 13 is a mature product of a gear reducer in the prior art. The gear reducer is an independent closed transmission device between the prime mover and the working machine, used to reduce the speed and increase the torque. The transmission end of the gear reduction member 13 is connected to the rotating shaft 7 on which the windward rotating blades 8 are installed, so that the rotating speed of the rotating shaft 7 section extending into the heat angle-shaped box 201 is less than the rotating speed of the rotating shaft 7 section connected to the windward rotating blades 8, thereby driving the air guiding and pushing plate 9 to rotate in the heat angle-shaped box 201 at a low speed.

[0037] Embodiment Four:

[0038] On the basis of the first embodiment, it is further described that a collision block 14 is arranged on the inner side wall of the inner arc segment 5. The collision block 14 is made of rubber. The air guiding and pushing plate 9 has an outer eight-shaped bevel structure on both sides, and a deformed arc elastic sheet 15 is arranged at the outer end of the air guiding and pushing plate 9. The deformed arc elastic sheet 15 can be a steel elastic sheet and is in an arc-shaped arched structure. When the air guiding and pushing plate 9 rotates, the contact between the deformed arc elastic sheet 15 and the collision block 14 causes the inner arc segment 5 to deflect and vibrate, and the rubber material of the collision block 14 avoids generating a large amount of noise when colliding with the deformed arc elastic sheet 15;

[0039] At the bottom end of the inner arc segment 5, there is a torsion spring plate 16 which consists of a double-ear shaft plate and a torsion spring fixedly sleeved on its shaft. The torsion spring on the torsion spring plate 16 is fixedly arranged with the turning end of the material receiving plate 10. When the material receiving plate 10 turns downward, the torsion spring can generate a spring force in the reset direction on the material receiving plate 10. The material receiving plate 10 is provided with a ventilation section, and ventilation openings are arranged on the ventilation section, and the diameter of the ventilation openings is smaller than the particle diameter of the grain, which is convenient for hot air to dry the grain above the material receiving plate 10 through the ventilation section. And a pushed arc block 17 vertically slides through the torsion spring plate 16. The pushed arc block 17 consists of a hemispherical block at the upper part and a vertical rod at the bottom end. The vertical rod vertically slides through the double-ear shaft plate on the torsion spring plate 16. At the same time, when the material receiving plate 10 resets under the action of the torsion spring, the arc-shaped surface of the hemispherical block of the pushed arc block 17 coincides with the movement track of the deformed arc elastic sheet 15. The bottom end of the pushed arc block 17 is movably arranged with the material receiving plate 10. Specifically, the pushed arc block 17 and the material receiving plate 10 are connected by means of hinge or separated contact, which is convenient for the pushed arc block 17 to drive the lower material receiving plate 10 to turn downward when it moves downward under the downward pressure. When the air guiding push plate 9 rotates, it will drive the deformed arc elastic sheet 15 to push the pushed arc block 17 to move downward. And the acting forces of the pushed arc block 17 and the torsion spring plate 16 on the material receiving plate 10 are opposite to each other, which can make the material receiving plate 10 deflect and vibrate. With the intermittent collision and pushing of the deformed arc elastic sheet 15 on the four air guiding push plates 9 against the pushed arc block 17, the grain above the material receiving plate 10 close to the adjacent hot angular boxes 201 is vibrated and thrown upward and evenly dried by the hot air, making the drying effect of the grain more uniform;

[0040] On the side wall of the tower dryer housing 1, a first driving and pushing member 18 and a second driving and pushing member 19 are respectively arranged, and the first driving and pushing member 18 and the second driving and pushing member 19 are composed of any one of a screw motor, an electric telescopic rod, and a linear slide rail. The first driving and pushing member 18 and the second driving and pushing member 19 are respectively used for the pushing movement of the equalizing plate 2 and the intermittent opening and closing plate 4. At the same time, the power control ends of the first driving and pushing member 18 and the second driving and pushing member 19 are connected to the preset power supply of the tower dryer housing 1.

[0041] The working principle is as follows: Through the quantitative lifting and conveying equipment, a quantitative amount of grain is put onto the upper surface of the equalizing plate 2 at the feeding end of the tower dryer housing 1. The scraping flat plate frame 11 is driven by the first driving and pushing member 18 to evenly scrape the grain into the quantitative grain storage port 3. The second driving and pushing member 19 is started to connect the discharge port 12 on the intermittent opening and closing plate 4 with the discharge end of the quantitative grain storage port 3. With the cyclic opening of the above steps, a quantitative amount of grain is intermittently put onto the lower drying assembly 101 for drying, avoiding the difficult-to-disperse drying caused by the large discharge of grain at one time;

[0042] The falling grain is first evenly dispersed by being shunted on both sides by the angular parts of the hot angular box 201. The dispersed grain will vertically fall under the limitation and block of the adjacent inner arc segments 5 of the hot angular box 201, so that there is a gap between the air-permeable part 6 on the inner arc segment 5 and the grain falling path, facilitating the hot air to pass through the air-permeable part 6 and the air vent section of the material-bearing plate 10 to dry the grain from the side and the lower side. At the same time, the air passing through the hot air inlet pipe 301 will drive the air guide and push plate 9 on the rotating shaft 7 to rotate through the windward rotating blades 8, and the air guide and push plate 9 rotates at a reduced speed under the cooperation of the gear reducer 13. The inclined sides on both sides of the air guide and push plate 9 can introduce the hot air into the air-permeable parts 6 on both sides, and the deformation arc elastic piece 15 at the outer end of the air guide and push plate 9 will successively push and squeeze the collision block 14 and the pushed arc block 17 in a cycle. The extrusion thrust received by the collision block 14 will be transmitted to the inner arc segment 5 to vibrate, and the cooperation of the pushed arc block 17 and the torsion spring plate 16 can vibrate the material-bearing plate 10. Furthermore, the grain falling above the material-bearing plate 10 can be made to jump under the action of the vibration force, and fall into the lower hot angular box 201 through the gap between the adjacent material-bearing plates 10 for circulation, extending the residence time of the grain in the hot angular box 201, enabling the grain to meet the drying requirements with a single lift or reducing the number of lifts, reducing the breakage rate of the grain caused by collisions, and improving the single drying efficiency of the grain.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
