Description

Technical Field

[0001] The utility model belongs to the technical field of grain drying equipment, in particular to a dust removal device for a grain dryer. Background Art

[0002] Grains refer to various plants or crops cultivated in agriculture, mainly including wheat, beans, whole grains and rice. As staple food, grains can provide the human body with abundant nutrients such as carbohydrates, proteins, dietary fiber and vitamins. Grain dryers are a type of equipment specially used to reduce the moisture content of grain kernels. By reducing the moisture content of grain kernels, grain dryers can effectively prevent grains from becoming moldy and deteriorating during storage, thereby ensuring the quality of grains and food safety.

[0003] During long-term observation, it is found that grain dryers will inevitably produce a certain amount of dust during operation, which mainly comes from impurities carried by the grains themselves. During the drying process, fine particles in these dusts may adhere to the fan with the flow of hot air, causing the fan to be blocked, resulting in poor ventilation inside the machine. At the same time, the dust on the grains will also contaminate the grains, causing the grain quality to decline. The dust on the grains will also breed pests in the grains, further damaging the quality of the grains and causing the grains to deteriorate.

[0004] To this end, the utility model provides a grain dryer dust removal device. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] like Figures 1 to 5As shown, a grain dryer dust removal device described in an embodiment of the utility model comprises a dust removal box 1; a motor 11 is provided on the top of the dust removal box 1; a plurality of first fixing rods 12 are fixedly connected to the outer wall of the motor 11; the end of the first fixing rod 12 is fixedly connected to the top of the dust removal box 1; a first gear 13 is fixedly connected to the output end of the motor 11; the first gear 13 is rotatably connected to the dust removal box 1; a second gear 14 is rotatably connected to the top of the dust removal box 1; the first gear 13 is meshed with the second gear 14; a first connecting rod 15 is fixedly connected to the bottom of the second gear 14; a drying box 16 is fixedly connected to the bottom of the inner side wall of the dust removal box 1; the first connecting rod 15 passes through the top of the drying box 16 and rotates in the middle of the drying box 16; the middle of the first connecting rod 15 A plurality of fan blades 17 are fixedly connected; a first screen 114 is fixedly connected to the side wall of the drying box 16; the first screen 114 is arranged above the fan blades 17; a third gear 18 is fixedly connected to the middle of the output end of the motor 11; a fourth gear 19 is rotatably connected to the top of the dust removal box 1; the third gear 18 is meshed with the fourth gear 19; a second connecting rod 110 is fixedly connected to the bottom of the fourth gear 19; a dust collecting box 111 is fixedly connected to the bottom of the inner side wall of the dust removal box 1; a fan base 112 is fixedly connected to the end of the second connecting rod 110; a plurality of fan blades 113 are fixedly connected to the side wall of the fan base 112; a second screen 115 is fixedly connected to the top of the drying box 16; the second screen 115 is fixedly connected to the intersection of the dust collecting box 111 and the drying box 16;During operation, the staff turns on the motor 11, and the motor 11 drives the first gear 13 to rotate. Because the first gear 13 is meshed with the second gear 14, the second gear 14 will rotate with the rotation of the first gear 13. When the second gear 14 rotates, it will drive the first connecting rod 15 and the fan blades 17 at the bottom to rotate. The fan blades 17 rotate and blow the grains placed on the top of the first sieve 114, and blow the dust carried by the grains to the top of the drying box 16. At this time, the motor 11 drives the third gear 18 to rotate. Because the third gear 18 is meshed with the fourth gear 19, the fourth gear 19 will rotate with the rotation of the third gear 18. When the fourth gear 19 rotates, it will drive the second connecting rod 110 at the bottom to rotate, and the rotation of the second connecting rod 110 will drive the fan base 112 and the fan blades 113 at the end to rotate. At this time, the rotation of the fan blades 113 will guide the dust on the top of the drying box 16 from the junction of the drying box 16 and the dust box 111 to the inside of the dust box 111. This step is achieved by setting the motor 11 , the first gear 13, the second gear 14, the first connecting rod 15 and the fan blades 17 can continuously disperse the grains accumulated on the top of the first screen 114, blow the dust carried by the grains to the top of the drying box 16, and prevent the dust from settling at the bottom of the drying box 16 and affecting the subsequent dust removal effect. By setting the first screen 114 and the second screen 115, the grains can be kept inside the drying box 16 while being blown away by the fan blades 17, and the grains can be prevented from falling to the bottom of the first screen 114 and being broken by the fan blades 17, while preventing the fallen grains from causing damage to the fan blades 17. By setting the motor 11, the third gear 18, the fourth gear 19, the second connecting rod 110, the fan base 112 and the fan blades 113, the dust raised inside the drying box 16 can be guided, and the dust can be transported from the inside of the drying box 16 to the inside of the dust collecting box 111, so that the dust attached to the grains can be transferred to the inside of the dust collecting box 111, reducing the situation in which the dust on the grains causes bacteria and pests to breed in the grains, destroying the quality of the grains and causing the grains to deteriorate. ;

[0026] Further, such as Figure 3 and Figure 4As shown, the bottom surface of the top of the dust removal box 1 is fixedly connected to the fan box 2; the second connecting rod 110 rotates inside the fan box 2; the bottom of the fan box 2 is fixedly connected to the third screen 21; the fan base 112 and the fan blades 113 are arranged inside the fan box 2; the bottom of the fan base 112 is fixedly connected to a thin rope 22; the thin ropes 22 are multiple and evenly distributed at the bottom of the fan base 112; each end of the thin rope 22 is fixedly connected to a magnetic ball 23; the inner wall of the fan box 2 is fixedly connected to a magnetic ball 23. The motor 11 drives the third gear 18 to rotate, because the third gear 18 is meshed with the fourth gear 19, the fourth gear 19 will rotate with the rotation of the third gear 18, and the rotation of the fourth gear 19 will drive the second connecting rod 110 at the bottom to rotate, and the rotation of the second connecting rod 110 will drive the fan base 112 at the end to rotate, and the bottom of the fan base 112 is fixed with a plurality of thin ropes 22 and magnetic balls 23, which will also rotate with the rotation of the fan base 112. At this time, the magnetic block 24 corresponding to the magnetic ball 23 will attract the magnetic ball 23 during the rotation of the magnetic ball 23. This step can reduce the situation that dust enters the fan box 2 and adheres to the fan blades 113, affecting the insufficient wind output of the fan blades 113, and reduce the dust from the drying box 16 to the fan blades 113 because the wind force is too small. In the case where the grains and dust cannot be separated inside the dust box 111, a thin rope 22, a magnetic ball 23 and a magnetic block 24 are arranged. When the fan base 112 rotates, the thin rope 22 and the magnetic ball 23 are driven to rotate so that the magnetic ball 23 is continuously attracted to the magnetic block 24 arranged on the top of the third screen 21. During the attraction, the fan box 2 and the third screen 21 are vibrated to shake off the dust attached to the third screen 21, thereby reducing the influence of the third screen 21 on the guiding effect of the fan blades 113 on the dust.

[0027] Further, such as Figures 1 to 5As shown, the top of the dust removal box 1 is fixedly connected with a water tank 3; the bottom of the water tank 3 is fixedly connected with a water spray pipe 31; the water spray pipe 31 simultaneously penetrates the dust removal box 1, the dust collecting box 111 and the top of the fan box 2; the water spray pipe 31 is arranged on the top of the fan base 112; the side wall of the dust collecting box 111 is provided with a water pump 32; the water outlet end of the water pump 32 is fixedly connected with a water outlet pipe 33; the middle part of the water outlet pipe 33 simultaneously penetrates the dust removal box 1 and the side wall of the dust collecting box 111; the end of the water outlet pipe 33 is fixedly connected to the top of the water tank 3; the water inlet end of the water pump 32 is fixedly connected to a water inlet pipe 34; when working, the staff stores water inside the water tank 3, and the water flows from the inside of the water tank 3 along the water spray pipe 31 and sprays on the dust collecting box 1 11, and finally gathered at the bottom of the dust box 111, then the water inlet pipe 34 is opened, the water flow at the bottom of the dust box 111 is pumped into the water inlet pipe 34, and then flows back to the inside of the water tank 3 along the water outlet pipe 33. In this step, the dust inside the dust box 111 can be reduced by setting the water tank 3 and the water spray pipe 31. After the dust meets the water, it will be quickly absorbed and condensed at the bottom of the dust box 111, which can reduce the dust floating inside the dust box 111 and reduce the diffusion and propagation range of the dust. By setting the water pump 32, the water outlet pipe 33 and the water inlet pipe 34, the water flow gathered at the bottom of the dust box 111 can be pumped back into the water tank 3, the water flow is recycled, and the waste of water resources is reduced.

[0028] Further, such as Figure 3 and Figure 5 As shown, a baffle 4 is fixedly connected to the middle of the second connecting rod 110; the baffle 4 is arranged at the end of the water spray pipe 31; the baffle 4 is provided with a notch 41; the size of the notch 41 is not less than the diameter of the water spray pipe 31; when working, the motor 11 drives the third gear 18 to rotate, because the third gear 18 is meshed with the fourth gear 19, the fourth gear 19 will rotate with the rotation of the third gear 18, and the rotation of the fourth gear 19 will drive the second connecting rod 110 at the bottom to rotate, and the rotation of the second connecting rod 110 will drive the baffle at the end 4 rotates, and the position of the notch 41 is constantly changed while the baffle 4 rotates. In this step, by setting the baffle 4 and the notch 41, the time of water spraying can be controlled when the water spray pipe 31 sprays water to the inside of the dust collecting box 111 to reduce dust. When the notch 41 rotates to the end position of the water spray pipe 31, water can be sprayed out from the water spray pipe 31. When the notch 41 leaves the end position of the water spray pipe 31, the baffle 4 blocks the port of the water spray pipe 31 so that the water inside the water spray pipe 31 cannot be sprayed out, thereby improving the efficiency of water spraying and reducing dust and further reducing the waste of water resources.

[0029] Further, such as Figures 3 to 5As shown, a dust bag 5 is fixedly connected to the end of the water inlet pipe 34; a plurality of air holes are provided on the side wall of the dust bag 5; the dust bag 5 has good water resistance and wear resistance; when working, the water pump 32 will draw water back from the water inlet pipe 34, and the water will first enter from the side wall of the dust bag 5 and then flow into the water inlet pipe 34. In this step, by setting the dust bag 5, dust in the water can be filtered when the water pump 32 draws back the water flow, thereby reducing the situation in which the water tank 3, the water spray pipe 31, the water pump 32, the water outlet pipe 33 and the water inlet pipe 34 are blocked due to the entry of dust, thereby reducing the failure of water flow dust reduction.

[0030] Further, such as Figure 3 and Figure 4 As shown, the inner wall of the dust bag 5 is fixedly connected with a second fixing rod 6; the second fixing rod 6 is in an "S" structure; in this step, by setting the second fixing rod 6 to be in an "S" structure, the contact area between the dust bag 5 and the water flow inside the dust collecting box 111 can be increased, the filtering efficiency of the dust bag 5 can be improved, and the water tank 3, the water spray pipe 31, the water pump 32, the water outlet pipe 33 and the water inlet pipe 34 can be further reduced. The blockage caused by dust entering the water tank 3, the water spray pipe 31, the water pump 32, the water outlet pipe 33 and the water inlet pipe 34 leads to the failure of water flow dust reduction.

[0031] Working principle: the staff turns on the motor 11, and the motor 11 drives the first gear 13 to rotate. Because the first gear 13 is meshed with the second gear 14, the second gear 14 will rotate with the rotation of the first gear 13. The rotation of the second gear 14 will drive the first connecting rod 15 and the fan blade 17 at the bottom to rotate. The fan blade 17 rotates to blow the grains placed on the top of the first screen 114, and blows the dust carried by the grains to the top of the drying box 16. At this time, the motor 11 drives the third gear 18 to rotate. Because the third gear 18 is meshed with the fourth gear 19, the fourth gear 19 will rotate with the rotation of the second gear 14. The motor 11 drives the third gear 18 to rotate. The fourth gear 19 drives the second connecting rod 110 at the bottom to rotate while the third gear 18 rotates. The rotation of the second connecting rod 110 drives the fan base 112 and the fan blades 113 at the end to rotate. At this time, the rotation of the fan blades 113 guides the dust on the top of the drying box 16 from the junction of the drying box 16 and the dust box 111 to the inside of the dust box 111. The motor 11 drives the third gear 18 to rotate. Because the third gear 18 is meshed with the fourth gear 19, the fourth gear 19 will rotate with the rotation of the third gear 18. At the same time as the fourth gear 19 rotates, When the fan base 112 rotates, the second connecting rod 110 at the bottom will be driven to rotate, and the rotation of the second connecting rod 110 will drive the fan base 112 at the end to rotate. The bottom of the fan base 112 is fixed with a plurality of thin ropes 22 and a magnetic ball 23, which will also rotate with the rotation of the fan base 112. At this time, the magnetic block 24 corresponding to the magnetic ball 23 will attract the magnetic ball 23 during the rotation of the magnetic ball 23. The staff stores water inside the water tank 3, and the water flows from the inside of the water tank 3 along the water spray pipe 31 to the inside of the dust box 111, and finally gathers at the bottom of the dust box 111. Then, the water inlet pipe 34 is opened to spray the bottom of the dust box 111. The water flow is drawn in from the water inlet pipe 34 and then flows back to the inside of the water tank 3 along the water outlet pipe 33. The motor 11 drives the third gear 18 to rotate. Since the third gear 18 is meshed with the fourth gear 19, the fourth gear 19 will rotate with the rotation of the third gear 18. The rotation of the fourth gear 19 will drive the second connecting rod 110 at the bottom to rotate, and the rotation of the second connecting rod 110 will drive the baffle 4 at the end to rotate. The rotation of the baffle 4 will continuously change the position of the notch 41, and the water pump 32 will draw water back from the water inlet pipe 34. The water will first enter from the side wall of the dust bag 5 and then flow into the water inlet pipe 34.
