Description

Technical Field

[0002] Food is the primary need of the people. As one of the necessities for human survival, my country attaches great importance to grain production and has designated special farmland protection areas and prohibited development, mainly to prevent food shortages. Grain is not suitable for storage after harvesting, and too much moisture in the grain will accelerate the mold and deterioration of the grain. According to relevant statistics, the proportion of grain that becomes moldy and deteriorates in my country each year is as high as about 5% because there is no time to dry the grain. Therefore, in order to prevent this kind of situation, a grain dryer for drying grain has appeared on the market.

[0003] A grain dryer with application number CN201821680578.6 comprises a dryer body, which is a temporary storage bin, a drying chamber and a discharging chamber from top to bottom, wherein the temporary storage bin, the drying chamber and the discharging chamber are connected in sequence, and the lower part of the temporary storage bin is provided with a preheating blind pipe extending upward, and the side wall of the preheating blind pipe is provided with an air outlet, and the bottom of the preheating blind pipe is connected with an external hot air source through a guide pipe; hot air inlet channels and hot air return channels are alternately provided in the drying chamber, and the side walls of the hot air inlet channels and the hot air return channels are both orifice plate side walls, and a fan air inlet is provided on one side wall of the discharging chamber and an air outlet is provided on the other side, and observation and maintenance windows are provided on the air inlet cover corresponding to each hot air inlet channel position. The utility model has the advantage that when the orifice plate side wall is blocked, the bran and impurities accumulated on the orifice plate side wall can be removed in time, thereby ensuring the smooth flow of the hot air inlet channel, reducing energy consumption, and improving drying efficiency.

[0004] The comparison device is provided with an anti-blocking structure, which is cleaned by manual hooking. This structure not only wastes manpower, but also a large amount of impurities are blocked in the side walls, which will prevent the material from entering the drying chamber, resulting in low drying efficiency and failure to dry the grain in time.

[0005] A grain dryer with application number CN201620108342.X; comprising a raw material storage bin and an elevator, the end of the elevator is connected to two feed bins at the top of the dryer, the dryer comprises an inner cylinder and an outer cylinder, a feed bin and a dust collector are arranged on the top of the outer cylinder, a distributor is installed at a position corresponding to the lower part of the feed bin inside the outer cylinder, a hot air inlet duct is arranged at the lower part of the outer cylinder, a discharge port is arranged at the bottom of the outer cylinder, the air outlet duct of the dust collector is connected to the air inlet of the lower part of the inner cylinder, an exhaust gas discharge duct is arranged at the top of the inner cylinder, several layers of hot air flow baffles are arranged inside the inner cylinder, and several layers of inclined circular unloading plates are arranged at the lower part of the distributor; it has the advantages of small footprint, small investment, small loss, small power consumption, high thermal energy utilization rate, large output, safe operation, low failure rate, low breakage, low operation cost, thorough material drying, long service life and simple operation.

[0006] The comparison device uses a hot air inlet duct to increase the temperature of the inner drum to dry the grain, but the grain accumulates on the inside of the inner drum, and the drying efficiency of the grain on the outside is faster than that on the inside, resulting in uneven heating of the grain. The moisture content of the grain on the inside is too high, and it is easy to mold and deteriorate when stored in a warehouse.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0034] See also Figure 1-9 The present invention provides a technical solution: a drum-type grain dryer with uniform heating effect, including a base 1, a storage chamber 2, a feeding port 3, a storage slot 4, a first motor 5, a fan 6, an ash storage tank 7, a filter screen 8, a sliding track 9, a sliding plate 10, a first sliding rod 11, a rolling wheel 12, a first telescopic spring 13, a connecting rod 14, a drying barrel 15, a slide 16, a second sliding rod 17, a second telescopic spring 18, a limit rod 19, a second motor 20, a stirring frame 21, a blower 22, an air inlet pipe 23, a radiator 24 and an air vent 25.

[0035] A material storage chamber 2 is provided inside the base 1, and a material inlet 3 is provided at the lower end of the material storage chamber 2; a material storage slot 4 is provided inside the base 1, and a first motor 5 is fixedly installed inside the material storage slot 4, and a fan 6 is fixedly installed at the output end of the first motor 5; an ash storage slot 7 is provided inside the base 1, and a filter screen 8 is fixedly installed inside the ash storage slot 7;

[0036] according to Figure 1-3 As shown, the storage chamber 2 is a trapezoidal structure when viewed from the front, and the feed port 3 at the lower end of the storage chamber 2 and the sliding plate 10 are distributed in correspondence with each other up and down; the fan 6 and the storage slot 4 form a rotating structure, and the storage slot 4 and the ash storage slot 7 are distributed in correspondence with each other on the left and right about the midpoint of the feed port 3;

[0037] The structure is achieved by opening a storage chamber 2 on the inner side of a base 1. When grains fall from the storage chamber 2 to the feed port 3, a first motor 5 on the inner side of a storage trough 4 is operated. The output end of the first motor 5 drives a fan 6 to rotate. The wind force generated by the fan 6 blows dust on the outer side of the grains to the inner side of an ash storage trough 7. The grains are intercepted by a filter screen 8 on the inner side of the ash storage trough 7, thereby separating the dust and the grains, and preventing dust on the outer side of the grains from entering the inner side of a drying barrel 15, occupying space, and causing trouble to subsequent work.

[0038] A sliding track 9 is fixedly installed on the inner side of the base 1, and a sliding plate 10 is nested on the inner side of the sliding track 9, and the sliding plate 10 is arranged at the lower end of the feeding port 3. A first sliding rod 11 is passed through the inner side of the base 1, and a rolling wheel 12 is fixedly installed on the tail end of the first sliding rod 11. A first telescopic spring 13 is fixedly installed on the outer side of the base 1, and the upper end of the first telescopic spring 13 is fixedly connected to the outer side of the first sliding rod 11. A connecting rod 14 is connected to the outer bearing of the sliding plate 10, and a drying barrel 15 is connected to the tail end bearing of the connecting rod 14. A sliding groove 16 is opened on the inner side of the base 1, and a second sliding rod 17 is nested in the sliding groove 16. The base 1 is fixedly installed with a second telescopic spring 18, and the upper end of the second telescopic spring 18 is fixedly connected to the lower end of the drying barrel 15, a limiting rod 19 is fixedly installed at the lower end of the drying barrel 15, and a second motor 20 is fixedly installed at the lower end of the drying barrel 15, and a vent hole 25 is opened inside the drying barrel 15, a stirring frame 21 is fixedly installed at the output end of the second motor 20, and the stirring frame 21 is arranged inside the drying barrel 15, a blower 22 is fixedly installed outside the base 1, and an air inlet pipe 23 is fixedly connected to the outside of the blower 22, a radiator 24 is fixedly connected to the tail end of the air inlet pipe 23, and the radiator 24 is fixedly installed inside the base 1;

[0039] according to Figure 1-2 , Figure 4-9As shown, the first sliding rod 11 and the base 1 form a sliding structure, and the first sliding rod 11 and the base 1 form an elastic structure through the first telescopic spring 13; the sliding plate 10 and the base 1 form a sliding structure through the sliding track 9, and the sliding plate 10 and the connecting rod 14 form a rotating structure; the rolling wheel 12 and the side end of the sliding plate 10 form a rotating structure, and the first sliding rod 11 at the upper end of the rolling wheel 12 and the rear end of the sliding plate 10 form a clamping structure; the second sliding rod 17 and the base 1 form a sliding structure through the slide groove 16, and the drying barrel 15 at the upper end of the second sliding rod 17 and the base 1 form an elastic structure through the second telescopic spring 18; the connecting rod 14 and the drying barrel 15 form a rotating structure, and the connecting rod 14 is symmetrically arranged in two groups about the midpoint of the drying barrel 15, and the drying barrel 15 and the stirring frame 21 form a rotating structure; the air inlet pipe 23 runs through the inner side of the base 1, and the radiator 24 at the rear end of the air inlet pipe 23 is symmetrically arranged in four groups about the center of the base 1;

[0040] With this structure, when the grain enters the inner side of the drying barrel 15 from the feeding port 3, when the grain inside the drying barrel 15 reaches a certain weight, the second telescopic spring 18 at the lower end will be squeezed, so that the drying barrel 15 moves downward through the second sliding rod 17. When the drying barrel 15 moves downward, the sliding plate 10 is driven to slide along the inner side of the sliding track 9 through the connection of the connecting rod 14 to close the corresponding feeding port 3 above and below. When sliding, after the end of the sliding plate 10 moves to the lower end of the rolling wheel 12, the rolling wheel 12 loses the limit of the sliding plate 10, and the elastic force of the first telescopic spring 13 is used to make the first sliding rod 11 drive the rolling wheel 12 to move downward, and engage the sliding plate 10 to prevent the sliding plate 10 from moving when the grain is discharged. Through this structure, the effect of quantitative feeding is achieved, and the poor drying effect caused by excessive feeding and the drying efficiency affected by too little feeding are prevented. A blower 22 is fixedly installed on the outside of the base body 1, and the air inlet pipe 23 is used to The heat dissipated by the radiator 24 is evenly insulated through the air holes 25 on the inner side of the drying barrel 15. At this time, the second motor 20 is operated. After the operation of the second motor 20, the stirring frame 21 on the inner side of the drying barrel 15 is rotated through the output end, so that the grain inside the drying barrel 15 is turned over to prevent the grain inside and outside from being heated unevenly, so that the moisture content inside the grain does not meet the standard. When the drying is completed, the grain is discharged through the discharge port. After the grain is discharged, the first sliding rod 11 is pulled to make the sliding plate 10 lose the engagement. The elastic force of the second telescopic spring 18 is used to push the drying barrel 15 to reset, so that the sliding plate 10 is moved to the right side through the connection of the connecting rod 14, and the feeding port 3 is in an open state. The above-mentioned actions are repeated to dry the grain.
