[0046] Please see attached Figures 1 to 7 A mobile dryer in one embodiment of the present invention includes a mobile body 10, a dryer assembly 20 and a driving mechanism 30, wherein:

[0047] The dryer assembly 20 is hinged on the mobile body 10, and the dryer assembly 20 has a working position and a transport position. When the dryer assembly 20 is in the transport position, the dryer assembly 20 is placed flat on the mobile body 10. When the dryer assembly 20 is in the working position, the dryer assembly 20 is perpendicular to the mobile body 10.

[0048] The driving mechanism 30 includes a connecting end 310 and a driving end 320 which are arranged relatively to each other along its own extension direction. The connecting end 310 is connected to the mobile vehicle body 10, and the driving end 320 is connected to the dryer assembly 20. The driving mechanism 30 drives the dryer assembly 20 to rotate around a hinge fulcrum so that the dryer assembly 20 switches between the working position and the transport position.

[0049] Specifically, the mobile vehicle body 10 is used as the basic carrier. Preferably, an ordinary vehicle is used as the means of transportation. It is not too high or too wide and can be driven on the road (including rural roads), thereby reducing transportation costs. The dryer assembly 20 can dry the grain on site, and the dryer assembly 20 is hinged on the mobile vehicle body 10.

[0050] Workflow: Drive the mobile vehicle body 10 to the target location, such as the road beside the field. When the dryer needs to be moved, the dryer assembly 20 can be driven by the driving mechanism 30 to rotate around the hinge fulcrum to a position flat on the mobile vehicle body 10 (i.e., the transport position). This design greatly reduces the space occupied by the equipment during transportation and improves the portability and flexibility of the equipment. Preferably, the height is less than 4.2 meters in the transport position, and most roads can be traveled. When the driving mechanism 30 is started, it will push the dryer assembly 20 to rotate around the hinge fulcrum, thereby enabling the dryer assembly 20 to switch to the working position.

[0051] Compared with trailer dryers, the present application does not require an additional towing vehicle, and the height can be less than 4.2 meters, so it can travel on most roads and can be equipped with an independent heat source; compared with small household mobile dryers, the present application dryer can have a larger capacity, and a larger single drying volume than small household dryers, so it can achieve emergency treatment of grains in a larger area; the present application solves the current problem of dryer mobility, and can achieve mobile drying within the region, large-scale emergency and other problems. The mobile vehicle body 10 can be driven directly to the farmer's field, can be directly installed for drying, and finally directly put into the grain warehouse, reducing turnover costs; the mobile vehicle body 10 can use a standard truck, and in the off-season, the user can disassemble the dryer assembly 20 and drive mechanism and other modules for cargo transportation, so as to achieve multiple uses of one machine.

[0053] Specifically, the chassis 110 serves as the foundation of the entire mobile vehicle body 10 and provides stable support. Through fixed connection with the first frame 120, a stable overall structure is formed, which can withstand the weight and vibration of the dryer assembly 20 during operation, ensuring the stable operation of the equipment; the articulated design of the dryer assembly 20 and the first frame 120 enables the dryer assembly 20 to be flexibly switched between the working position and the transport position, thereby improving the portability and adaptability of the equipment;

[0054] As a preferred embodiment, a first connecting ear plate 130 is provided on the top of the first frame 120, and a second connecting ear plate 230 is provided on the bottom of the dryer assembly 20 in one-to-one correspondence with the first connecting ear plate 130. The first connecting ear plate 130 is provided with a first connecting hole (not shown) for the hinge shaft 240 to pass through, and the second connecting ear plate 230 is provided with a second connecting hole (not shown) corresponding to the first connecting hole. The first connecting ear plate 130 is hinged to the second connecting ear plate 230 through the hinge shaft 240 passing through the first connecting hole and the second connecting hole.

[0055] In this embodiment, the hinge point is precisely and stably located by designing the first connecting ear plate 130 and the second connecting ear plate 230. The first connecting ear plate 130 and the second connecting ear plate 230 are arranged one-to-one, and the first connecting ear plate 130 and the second connecting ear plate 230 are firmly connected together by the hinge shaft 240 to form a hinge structure, thereby enhancing the strength and stability of the entire structure.

[0056] Furthermore, the dryer assembly 20 includes a dryer body 210 and a connecting plate 220, the dryer body 210 and the first frame 120 are hinged, the connecting plate 220 is connected to the dryer body 210 on one side close to the driving mechanism 30, and the driving end 320 of the driving mechanism 30 is hinged to the connecting plate 220.

[0057] In this embodiment, the dryer body 210 is hinged to the first frame 120, the structure of the dryer assembly 20 is more compact, the connecting plate 220 is connected to the side of the dryer body 210 close to the driving mechanism 30, the driving end 320 of the driving mechanism 30 is hinged to the connecting plate 220, and the connecting plate 220 provides a connection basis, so that the dryer body 210 can stably switch between the working position and the transport position.

[0058] As another preferred embodiment, it also includes a spiral grain feeder 40 and a primary cleaning screen 50, wherein the spiral grain feeder 40 includes a suction end 410 and a discharge end 420, and the primary cleaning screen 50 includes a feed end 510 and a discharge end (not shown in the figure), wherein the suction end 410 is used to suck in grains on the ground, the feed end 510 is connected to the discharge end 420, and the discharge end is connected to the grain inlet of the dryer body 210, and the grain that has been preliminarily screened by the primary cleaning screen 50 enters the dryer body 210 for drying.

[0059] Specifically, after the grain is harvested, the grain is sucked into the primary cleaning screen 50 for screening by the spiral grain feeder, and then discharged into the grain inlet of the dryer body 210, and enters the dryer body 210 to complete the drying process. Among them, the spiral grain feeder and the primary cleaning screen 50 can both adopt existing conventional equipment, which will not be described in detail here.

[0060] As another preferred embodiment, it also includes a support assembly (not shown) for supporting the mobile body 10, the support assembly includes two support units 60 arranged at intervals along the length direction of the mobile body 10, each support unit 60 includes a support cross bar 610 and two hydraulic support vertical bars 620 relatively arranged at both ends of the support cross bar 610, wherein when the hydraulic support vertical bars 620 are in an initial state, the mobile body 10 is in contact with the ground, and when the hydraulic support vertical bars 620 are in a jacking state, the mobile body 10 is separated from the ground.

[0061] Specifically, the setting of the support assembly enhances the stability of the mobile body 10, making the mobile body 10 stable, especially on uneven or soft ground. The hydraulic support vertical rod 620 can provide additional support force to prevent the body from tilting or collapsing due to uneven ground or excessive load. When the hydraulic support vertical rod 620 is in the initial state, the hydraulic support vertical rod 620 is in a retracted state, and the bottom of the mobile body 10 is in contact with the ground, which is convenient for the movement of the mobile body 10. When work is required, the hydraulic support vertical rod 620 is started and put in a jacking state, so that the body can be lifted and separated from the ground, so that the mobile body 10 is stable. The design of the support assembly enables the mobile body 10 to adapt to different working environments and ground conditions. Whether it is a flat hardened road surface or a soft muddy ground, the stability and safety of the body can be ensured by adjusting the height of the hydraulic support vertical rod 620.

[0062] Furthermore, a diesel generator 70 is further included, and the diesel generator 70 is connected to the top of the mobile vehicle body 10, and the diesel generator 70 is electrically connected to the dryer assembly 20. The diesel generator 70 can provide electricity for the dryer body 210 during use.

[0063] Furthermore, a diesel stove 80 is further included, and the diesel stove 80 is connected to the top of the mobile vehicle body 10 to provide a heat source for the dryer assembly 20. The diesel stove 80 can provide a heat source for the dryer body 210 through a burner.

[0064] Furthermore, the mobile body 10 also includes a second frame 140 , the driving mechanism 30 is arranged between the second frame 140 and the dryer assembly 20 , the second frame 140 includes a horizontal support plate 150 and a vertical support plate 160 , and the horizontal support plate 150 is connected to the top of the vertical support plate 160 .

[0065] Specifically, the second frame 140 provides a more stable support structure. The combination of the horizontal support plate 150 and the vertical support plate 160 forms a stable frame, which enhances the load-bearing capacity and anti-deformation ability of the vehicle body.

[0066] Please see attached Figures 8 to 17 As a preferred embodiment, the dryer body 210 includes a dryer body 2110, a grain feeding assembly 2120 and a material discharging assembly 2130, wherein:

[0067] The top of the dryer body 2110 is provided with a grain inlet (not shown), and the bottom of the dryer body 2110 is provided with a grain outlet 21110;

[0068] The grain feeding component 2120 is used to input the grain to be dried into the grain feeding port;

[0069] The dryer body 2110 includes a cold air drying section 21130 and at least one hot air drying section 21120, wherein the hot air drying section 21120 is located above the cold air drying section 21130, and each hot air drying section 21120 includes an upper drying section 21121 and a lower slow drying section 21122, wherein the food is dried by the upper drying section 21121 of the i-th hot air drying section 21120 and then enters the lower slow drying section 21122 of the i-th hot air drying section 21120. 22, after being kept warm in the lower slow-release section 21122 of the i-th hot air drying section 21120, it enters the upper drying section 21121 of the i+1-th hot air drying section 21120, and after being kept warm in the lower slow-release section 21122 of the N-th hot air drying section 21120, it enters the cold air drying section 21130, and after being cooled and dried in the cold air drying section 21130, it enters the discharge assembly 2130 through the grain outlet 21110; wherein, 1≤i≤N-1, i and N are both positive integers;

[0070] The discharge component 2130 discharges the dried grain.

[0071] Specifically, the grain to be dried is input into the top grain inlet of the dryer body 2110 through the grain feeding assembly 2120. The grain first enters the hot air drying section 21120, each of which includes an upper drying section 21121 and a lower slow drying section 21122. The grain is subjected to the action of hot air in the upper drying section 21121 for preliminary drying. The dried grain enters the lower slow drying section 21122 for heat preservation, so that the moisture inside the grain evaporates further and the grain is prevented from being damaged by over-drying. After passing through a hot air drying section 21120, the grain enters the next hot air drying section 21120 and the above process is repeated. This combination of multi-stage drying and slow drying can ensure that the grain is evenly and fully dried.

[0072] After the grain passes through the lower slow drying section 21122 of the last hot air drying section 21120, it enters the cold air drying section 21130. The cold air drying section 21130 is mainly used to cool the grain so that the grain reaches the required dryness and temperature before being discharged. The grain cooled and dried in the cold air drying section 21130 enters the discharge assembly 2130 through the bottom grain outlet 21110 of the dryer body 2110, and is finally discharged by the discharge assembly 2130.

[0073] In the present application, continuous and efficient drying of grain can be achieved through the combination of a multi-stage hot air drying section 21120 and a cold air drying section 21130. This drying method not only improves the drying efficiency, but also ensures the drying quality of the grain. Due to the combined effect of the hot air and the slow drying section, the drying quality of the grain is more uniform, avoiding local over-drying or over-wetting of the grain during the drying process.

[0074] The dryer of the present application can be applied to the drying of various grains, such as wheat, corn, rice, etc. This helps to meet the needs of different users and improve the utilization rate and economic benefits of the equipment.

[0075] Furthermore, the grain feeding component 2120 may be a feeding elevator 21210, and the discharging component 2130 may include a conveyor belt component 21310, a discharging elevator 21320, and a grain discharging pipe 21330, wherein the conveyor belt component 21310 receives grain from the grain outlet 21110, and then transports the grain to the discharging elevator 21320 to a certain height, and then discharges the grain through the grain discharging pipe 21330 to achieve loading.

[0076] As a preferred embodiment, each of the upper drying sections 21121 includes a first drying bin 211211, a hot air duct assembly 211212 and a material drop control assembly 211213, wherein the hot air duct assembly 211212 includes a first hot air duct assembly 2112121 arranged in the first drying bin 211211 and a second hot air duct assembly 2112124 connected to the outer wall of the dryer body 2110, a first air hole 2112122 connected to the first drying bin 211211 is provided on the wall surface of the first hot air duct assembly 2112121, an air inlet of the first hot air duct assembly 2112121 is connected to an air outlet of the second hot air duct assembly 2112124, an air outlet of the first hot air duct assembly 2112121 is connected to the outside of the dryer body 2110, and an air inlet of the second hot air duct assembly 2112124 is connected to an external hot air source;

[0077] The material dropping control component 211213 has an open position and a closed position, wherein when in the open position, the grain in the first drying bin 211211 of the i-th hot air drying section 21120 enters the lower buffer section 21122 of the i-th hot air drying section 21120, and after being kept warm in the lower buffer section 21122 of the i-th hot air drying section 21120, enters the first drying bin 211211 of the (i+1)-th hot air drying section 21120; when in the closed position, the grain stays in the first drying bin 211211.

[0078] Specifically, the hot air duct assembly 211212 includes a first hot air duct assembly 2112121 disposed in the first drying chamber 211211 and a second hot air duct assembly 2112124 connected to the outer wall of the dryer body 2110. The external hot air source passes through the air inlet of the second hot air duct assembly 2112124 to send the hot air into the second hot air duct assembly 2112124, and then passes through the air outlet of the second hot air duct assembly 2112124 to connect with the first hot air duct assembly 2110. The air inlet of 112121 is connected, so that the hot air is sent into the first hot air duct assembly 2112121. The wall of the first hot air duct assembly 2112121 is provided with first air holes 2112122. The hot air enters the first drying bin 211211 through these first air holes 2112122 to dry the grain in the bin. The dried hot air is discharged to the outside of the dryer body 2110 through the air outlet of the first hot air duct assembly 2112121.

[0079] The blanking control component 211213 has an open position and a closed position. When the blanking control component 211213 is in the open position, the grain in the first drying bin 211211 of the i-th hot air drying section 21120 can enter the lower slow recovery section 21122 of the i-th hot air drying section 21120 through the blanking port. In the lower slow recovery section 21122, the grain is insulated to further evaporate the moisture inside the grain, while preventing the grain from being damaged by over-drying. After passing the slow recovery section, the grain enters the first drying bin 211211 of the next hot air drying section 21120 again to repeat the above drying process. When the blanking control component 211213 is in the closed position, the grain stays in the first drying bin 211211 and does not enter the lower slow recovery section 21122, which helps to control the drying progress and ensure the drying quality.

[0080] It is worth noting that the hot air evenly enters the first drying chamber 211211 through the first air hole 2112122 on the wall of the first hot air duct assembly 2112121, ensuring that the grain is evenly heated during the drying process to avoid partial overdrying or overwetting. The material drop control assembly 211213 can flexibly control the timing of the grain drop to ensure that the residence time and drying degree of the grain during the drying process meet the process requirements. The shape of the first air hole 2112122 is preferably a fish scale hole.

[0081] Furthermore, the first hot air duct assembly 2112121 includes two layers of first hot air duct rows (not shown) vertically spaced apart, and each of the first hot air duct rows includes a plurality of first hot air ducts evenly spaced apart along the width direction of the dryer body 10, and a first stacking space 2112123 is formed between two adjacent first hot air ducts along the width direction.

[0082] Specifically, the design of the multi-layer hot air duct row increases the contact area between the hot air and the grain, allowing the hot air to more fully exchange heat with the grain, thereby improving the drying efficiency.

[0083] As a preferred embodiment, the drop control assembly 211213 includes a horizontal driving cylinder 2112131 and a first transverse baffle 2112132. The wall of the first drying bin 211211 is provided with a first through hole for the driving end of the horizontal driving cylinder 2112131 to pass through. The width of the first transverse baffle 2112132 is smaller than the width of the first drying bin 211211. The first transverse baffle 2112132 is connected to the driving end of the horizontal driving cylinder 2112131 and follows the horizontal driving cylinder. The driving end of 2112131 moves synchronously, and the first cross baffle 2112132 is provided with a first material dropping channel 2112133 corresponding to the first material stacking space 2112123 one by one, wherein, when in the open position, the first material dropping channel 2112133 and the first material stacking space 2112123 are arranged opposite to each other, and when in the closed position, the first material dropping channel 2112133 and the first material stacking space 2112123 are staggered to make the grain stay in the first drying bin 211211.

[0084] Specifically, the material dropping control assembly 211213 includes a horizontal driving cylinder 2112131 and a first transverse baffle 2112132. The wall of the first drying bin 211211 is provided with a first through hole for the driving end of the horizontal driving cylinder 2112131 to pass through. The horizontal driving cylinder 2112131 is connected to the first transverse baffle 2112132 through the hole. The width of the first transverse baffle 2112132 is smaller than that of the first drying bin 211211 so that When a horizontal baffle 2112132 moves, it can leave space for blanking or blocking materials. When the driving end of the horizontal driving cylinder 2112131 is extended, it drives the first horizontal baffle 2112132 to move horizontally. The first horizontal baffle 2112132 is provided with a first blanking channel 2112133 which corresponds one-to-one to the first material stacking space 2112123. The shape and position of the first blanking channel 2112133 match the first material stacking space 2112123. When the first transverse baffle 2112132 is in the open position, the first material drop channel 2112133 and the first material stacking space 2112123 are arranged opposite to each other, and the grain can fall from the first drying bin 211211 into the lower slow recovery section 21122 through these channels. When the first transverse baffle 2112132 is in the closed position, the first material drop channel 2112133 and the first material stacking space 2112123 are staggered. At this time, the grain is blocked by the first transverse baffle 2112132 and stays in the first drying bin 211211.

[0085] In this embodiment, by precise control of the horizontal driving cylinder 2112131, precise movement of the first transverse baffle 2112132 can be achieved, thereby precisely controlling the timing of grain dropping.

[0086] As another preferred embodiment, the blanking control component 211213 also includes a dead zone blanking valve plate 2112134, which is hinged to the inner wall of the first drying bin 211211, and the dead zone blanking valve plate 2112134 is located directly above the driving end of the horizontal driving cylinder 2112131, wherein, when in the open position, the dead zone blanking valve plate 2112134 is in a vertical state so that the first blanking channel 2112133 and the first stacking space 2112123 are arranged opposite each other, and when in the closed position, the dead zone blanking valve plate 2112134 is in an inclined state, and the dead zone blanking valve plate 2112134 covers the corresponding first blanking channel 2112133 so that the food stays in the first drying bin 211211.

[0087] In this embodiment, Figure 8 and Fig.13As shown, in addition to the original horizontal driving cylinder 2112131 and the first cross baffle 2112132, the blanking control component 211213 also adds a dead zone blanking valve plate 2112134. The dead zone blanking valve plate 2112134 is hinged to the inner wall of the first drying bin 211211, allowing the dead zone blanking valve plate 2112134 to switch between vertical and horizontal states. The dead zone blanking valve plate 2112134 is located directly above the driving end of the horizontal driving cylinder 2112131, forming a complementary blanking control mechanism with the first cross baffle 2112132.

[0088] like Fig.13 As shown, since the driving end of the horizontal driving cylinder 2112131 has a motion stroke, in order to adapt to this motion stroke, this embodiment reserves a certain gap between the left end of the first cross baffle 2112132 and the inner wall of the first drying bin 211211. If no treatment is done here, the grain will fall directly. Therefore, this embodiment designs a dead zone blanking valve plate 2112134. The dead zone blanking valve plate 2112134 and the first cross baffle 2112132 work together to more reliably control the falling of grain.

[0089] As a preferred embodiment, the cold air drying section 21130 includes a second drying chamber 21131, a cold air duct assembly 21132 and a discharging control assembly 21133, wherein the cold air duct assembly 21132 includes a first cold air duct assembly 211321 arranged in the second drying chamber 21131 and a second cold air duct assembly 211323 connected to the outer wall of the dryer body 2110, a second air hole 211322 connected to the second drying chamber 21131 is opened on the wall surface of the first cold air duct assembly 211321, an air inlet of the first cold air duct assembly 211321 is connected to an air outlet of the second cold air duct assembly 211323, an air outlet of the first cold air duct assembly 211321 is connected to the outside of the dryer body 2110, and an air inlet of the second cold air duct assembly 211323 is connected to an external cold air source;

[0090] The discharge control component 21133 has an open position and a closed position, wherein, when in the open position, the grain in the second drying bin 21131 enters the discharge component 2130 through the grain outlet 21110 ; when in the closed position, the grain stays in the second drying bin 21131 .

[0091] Specifically, the cold air duct assembly 21132 includes a first cold air duct assembly 211321 arranged in the second drying chamber 21131 and a second cold air duct assembly 211323 connected to the outer wall of the dryer body 2110. The external cold air source passes through the air inlet of the second cold air duct assembly 211323 to send cold air into the second cold air duct assembly 211323, and then passes through the air outlet of the second cold air duct assembly 211323 to connect with the air inlet of the first cold air duct assembly 211321. The first cold air duct assembly 211321 is connected with the outlet, thereby sending cold air into the first cold air duct assembly 211321. Second air holes 211322 are opened on the wall of the first cold air duct assembly 211321. Cold air or normal temperature air enters the second drying bin 21131 through these second air holes 211322 to cool and dry the grain in the bin. The cooled cold air is discharged to the outside of the dryer body 2110 through the outlet of the first cold air duct assembly 211321, completing a cold air cycle.

[0092] The discharge control component 21133 has an open position and a closed position, and is used to control the discharge of grain in the second drying bin 21131. When the discharge control component 21133 is in the open position, the grain in the second drying bin 21131 can enter the discharge component 2130 through the grain outlet 21110 and then be discharged from the dryer. When the discharge control component 21133 is in the closed position, the grain is blocked in the second drying bin 21131 and will not be discharged through the grain outlet 21110.

[0093] Furthermore, the first cold air duct assembly 211321 includes a plurality of first cold air ducts evenly spaced apart along the width direction of the dryer body 2110 , and a second stacking space 211324 is formed between two adjacent first cold air ducts along the width direction.

[0094] Specifically, in this embodiment, a plurality of first cold air ducts are evenly arranged along the width direction of the dryer body 2110 , thereby ensuring that the cold air is more evenly distributed in the second drying chamber 21131 .

[0095] As a preferred embodiment, the discharge control assembly 21133 includes a driving mechanism 211331, a crank slider mechanism 211332 and a second transverse baffle 211333, the crank slider mechanism 211332 is connected to the driving mechanism 211331, the second drying chamber 21131 is provided with a second through hole matching the crank slider mechanism 211332, and the width of the second transverse baffle 211333 is smaller than the width of the second drying chamber 21131;

[0096] The second transverse baffle 211333 is provided with a second material drop channel 211334 corresponding to the second material stacking space 211324 one by one. The second transverse baffle 211333 is connected to the crank slider mechanism 211332 and follows the crank slider mechanism 211332 to reciprocate in the lateral direction to control the connecting width between the second material drop channel 211334 and the second material stacking space 211324, thereby adjusting the amount of grain dropped.

[0097] Specifically, the driving mechanism 211331 drives the crank slider mechanism 211332 to make the second cross baffle 211333 reciprocate in the horizontal direction. The width of the second cross baffle 211333 is smaller than the width of the second drying bin 21131, so that the second cross baffle 211333 can reciprocate in the horizontal direction in the drying bin. The second cross baffle 211333 is provided with a second blanking channel 211334 corresponding to the second stacking space 211324.

[0098] By controlling the moving position of the second cross baffle 211333, the connecting width between the second feeding channel 211334 and the second stacking space 211324 can be adjusted. When the connecting width increases, the amount of grain falling increases; when the connecting width decreases, the amount of grain falling decreases. This adjustment method can accurately control the grain discharge amount according to actual needs.

[0099] As another preferred embodiment, it also includes a flattening assembly 2140, which includes a driving motor 21410, a speed reduction mechanism 21420, a first rotating spindle 21430, a second rotating spindle 21440 and a scraper 21450, wherein:

[0101] The second rotating main shaft 21440 is connected to the first rotating main shaft 21430 and moves synchronously with the first rotating main shaft 21430. The scraper 21450 is connected to the bottom of the second rotating main shaft 21440 and moves synchronously with the second rotating main shaft 21440 to scrape the grain located at the top of the dryer body 2110.

[0102] Specifically, the driving motor 21410 drives the first rotating main shaft 21430 to rotate through the speed reduction mechanism 21420, thereby driving the second rotating main shaft 21440 and the scraper 21450 to move synchronously, and the scraper 21450 performs a flattening operation on the top of the dryer body 2110, and can spread the grain quickly and evenly. This design improves the efficiency of spreading the grain, allowing the grain to be more fully exposed to the cold wind, thereby improving the drying effect.
