[0002] Seed coating refers to the use of adhesives or film-forming agents to wrap non-seed materials such as fungicides, pesticides, micro-fertilizers, plant growth regulators, colorants or fillers around seeds in order to make the seeds spherical or basically maintain their original shape, improve stress and disease resistance, accelerate germination, promote seedling formation, increase yield and improve quality.

[0003] The existing coating machine pushes the seeds in the coating drum upward by the rotation of the spiral blade, so that the seeds surge upward in the coating drum, realize the tumbling of the seeds, and make the poured liquid evenly adhere to the seeds.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] The following is combined with Figure 1 -Attached Figure 8 , describes in detail the technical solutions provided by each embodiment of the present invention.

[0021] Example 1: Reference Figure 1-Figure 8A dust-proof coating machine for corn seed processing comprises a bracket 1, and also comprises: a coating drum 11, the coating drum 11 is mounted on the bracket 1, and an inverted medicine drum 18 is mounted on the coating drum 11; a rotating shaft 14, which is rotatably connected in the coating drum 11, and a spiral blade 141 is fixedly connected to the rotating shaft 14; a first connecting rod 15 and a first telescopic rod 153 symmetrically rotatably arranged on the inclined wall 110 of the coating drum 11, one end of the first connecting rod 15 and the first telescopic rod 153 is rotatably connected, and a triangular dispersion area 150 is formed between the first connecting rod 15, the first telescopic rod 153 and the inclined wall 110, so as to disperse the seeds rolling in the coating drum 11; and when the rotation speed of the rotating shaft 14 is increased, the area of ​​the triangular dispersion area 150 is increased; the inclined wall 110 of the coating drum 11 The inclined wall 110 is symmetrically fixedly connected with a first mounting block 151 and a second mounting block 152, one end of the two first connecting rods 15 is rotatably connected to the two first mounting blocks 151, one end of the two first telescopic rods 153 is rotatably connected to the two second mounting blocks 152, and also includes a rotating rod 154, the first connecting rod 15 and the first telescopic rod 153 are both rotatably connected to the rotating rod 154; a fixed shaft 146 is fixedly connected to the top of the rotating shaft 14, a conical cover 148 is slidably connected to the fixed shaft 146, a fixed block 149 is fixedly connected to the top of the fixed shaft 146, and a spring 147 is sleeved on the fixed shaft 146 between the fixed block 149 and the conical cover 148; a second connecting rod 155 is rotatably connected to the rotating rod 154, and the second connecting rod 155 is rotatably connected to the rotating rod 154. One end of the rod 155 away from the rotating rod 154 is rotatably connected to the conical cover 148; it should be noted that the present device is not limited to the coating of corn seeds, but can also be used to coat other seeds; when the present device is in use, it can automatically adjust the area of ​​the triangular dispersion zone 150 formed between the first connecting rod 15 and the first telescopic rod 153 according to the rotation speed of the rotating shaft 14, so that when the triangular dispersion zone 150 is at a low rotation speed, the first connecting rod 15 and the first telescopic rod 153 are closer to the inclined wall 110 of the coating drum 11, thereby reducing the dispersion of the corn seeds in the lateral direction in the coating drum 11, so that the corn seeds close to the inner wall of the coating drum 11 can be dispersed and tumbled, and then the corn seeds close to the inner wall of the coating drum 11 can be better adhered to the liquid medicine. At high speed, the corn seeds in the coating drum 11 surge upward to an increased height, thereby increasing the upward distance of the conical cover 148. At this time, the upwardly moving conical cover 148 will pull the rotating rod 154 through the second connecting rod 155, so that the first telescopic rod 153 is extended, thereby increasing the area of ​​the triangular dispersion zone 150, which will cause the rotating rod 154, the first connecting rod 15, and the first telescopic rod 153 to move closer to the middle of the coating drum 11, thereby increasing the dispersion area of ​​the corn seeds in the lateral direction in the coating drum 11, and then, when the rotating shaft 14 is in a high speed state, the corn seeds with increased surge height can have a larger triangular dispersion zone 150, so that the corn seeds have a better rolling effect, which is further convenient for mixing the liquid medicine with the corn seeds.Secondly, when the rotation speed of the rotating shaft 14 increases, the spiral blades 141 will more efficiently make the corn seeds in the coating drum 11 surge upward, which will appropriately increase the spacing between the corn seeds, and then when the rotating rod 154, the first connecting rod 15, and the first telescopic rod 153 extend toward the middle of the coating drum 11, the impact force on the rotating rod 154, the first connecting rod 15, and the first telescopic rod 153 can be reduced, avoiding friction damage to the corn seeds and achieving a better coating effect; wherein, the conical cover 148 is located in the middle of the coating drum 11 and close to the opening of the coating drum 11, so the conical cover 148 can be used to prevent the corn seeds that surge upward from overflowing out of the coating drum 11. ;

[0022] The bracket 1 is fixedly connected with a mounting plate 140, and a motor 145 is installed on the mounting plate 140. A small pulley 143 is fixedly connected to the output end of the motor 145. A large pulley 142 is fixedly connected to the end of the rotating shaft 14. The large pulley 142 and the small pulley 143 are connected by a belt 144. Specifically, when in use, corn seeds are poured into the coating drum 11, and the motor 145 is started. The motor 145 drives the large pulley 142 through the small pulley 143, and then drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 causes the spiral blades 141 to stir the corn seeds and roll upward, and the corn seeds are moved to the coating drum 11. The tumbling corn seeds are sucked under the rotating shaft 14 again, and continue to be pushed upward by the spiral blades 141, thereby achieving the effect of tumbling the corn seeds in the coating cylinder 11; the medicine liquid is then poured into the medicine pouring cylinder 18, and the medicine liquid falls on the corn seeds, and in the tumbling state, the corn seeds are evenly attached to the medicine liquid; then, the speed of the motor 145 is adjusted to change the area of ​​the triangular dispersion zone 150, thereby adjusting the mixing efficiency of the corn seeds and the medicine liquid; and the triangular dispersion zone 150 can also improve the stability of the rotating shaft 14 during rotation, thereby increasing the service life of the device.

[0023] Example 2: Reference Figure 2 , Figure 3 , Figure 6 A dustproof coating machine for corn seed processing is basically the same as Example 1, and further: a discharge groove is opened on the coating cylinder 11, and a discharge guide plate 12 is installed on the outer wall of the coating cylinder 11 located in the discharge groove, and a baffle 13 is slidably connected to the discharge guide plate 12; when the corn seeds are coated, the baffle 13 is pulled off the discharge guide plate 12, and the coating cylinder 11 falls from the discharge groove onto the discharge guide plate 12 for discharge, thereby facilitating discharge.

[0024] Example 3: Reference Figure 3 , Figure 5 , Figure 6 , Figure 7, a dustproof coating machine for corn seed processing, which is basically the same as Example 2, and further includes: a dust hood 17 located above the coating cylinder 11, a first connecting pipe 171 is fixedly connected to the dust hood 17, a second connecting pipe 172 is rotatably connected to the first connecting pipe 171, a filter box 173 is installed on the end of the second connecting pipe 172, the filter box 173 is installed on the bracket 1, and a filter screen 174 is slidably connected to the filter box 173; during the corn seed coating process, dust can be sucked into the filter box 173 through the dust hood 17 and intercepted by the filter screen 174 to prevent dust from scattering.

[0025] A deodorizing box 175 is fixedly connected below the filter box 173. The deodorizing box 175 is filled with activated carbon adsorption particles. A blocking net 176 is provided at the bottom of the deodorizing box 175. Since some liquid medicines have a certain odor, in order to prevent the odor from spreading, the dust is blocked by the filter net 174, and then the activated carbon filter particles in the deodorizing box 175 are used to adsorb the odor, thereby effectively reducing the odor of the exhaust gas.

[0026] Example 4: Reference Figure 4 , Figure 5 , Figure 6 , Figure 8 , a dust-proof coating machine for corn seed processing, which is basically the same as Example 3, and further: an air inlet pipe 16 is installed on the outer wall of the coating cylinder 11, the air inlet pipe 16 leads to the coating cylinder 11, and a fan 165 is installed on the bracket 1, and the air outlet of the fan 165 is connected to the air inlet pipe 16; by blowing air into the coating cylinder 11 through the set air inlet pipe 16, the dust adhering to the corn seeds can be blown up, and the filled gas can enter the filter box 173, and there is no need to separately set a suction fan on the dust hood 17.

[0027] One end of the air inlet pipe 16 is movably connected to a ball nozzle 161, and an iron net is provided on the open end of the ball nozzle 161 to prevent corn seeds from entering the ball nozzle 161. A support plate 162 is fixedly connected to the outer wall of the ball nozzle 161, and a ball head 163 is rotatably connected to the support plate 162. A second telescopic rod 164 is movably connected to the ball head 163, and an end of the second telescopic rod 164 away from the ball head 163 is rotatably connected to one end of the rotating rod 154, so that when the second connecting rod 155 pulls the rotating rod 154, the ball nozzle 161 is tilted upward to form a tangential wind blowing toward the inner wall of the coating cylinder 11; when the rotating rod 154 is greatly pulled, the ball nozzle 161 will be pulled upward and tilted to one side through the second telescopic rod 164, which makes the ball nozzle 161 tilt upward and tilted to one side. The opening of the head nozzle 161 can be directed toward the inner wall of the coating cylinder 11, so that the wind ejected from the ball nozzle 161 can form tangential wind by relying on the inner wall of the coating cylinder 11. The tangential wind can circulate upward in the coating cylinder 11, and help the corn seeds to roll, so that the corn seeds roll more quickly and the mixing effect with the liquid medicine is better; because the second telescopic rod 164 is used to pull the ball nozzle 161, and the sliding of the second telescopic rod 164 has a certain stroke, when the rotating rod 154 is pulled slightly, the ball nozzle 161 will not rotate. At this time, the ball nozzle 161 blows air toward the middle of the coating cylinder 11, which can make the corn seeds close to the middle of the coating cylinder 11 be blown by the airflow, and then the dust adhering to the surface is blown and better discharged to the outside.

[0028] The present invention can automatically adjust the area of ​​the triangular dispersion zone 150 formed between the first connecting rod 15 and the first telescopic rod 153 according to the rotation speed of the rotating shaft 14, so that when the triangular dispersion zone 150 is at a low rotation speed, the first connecting rod 15 and the first telescopic rod 153 are closer to the inclined wall 110 of the coating drum 11, thereby reducing the dispersion of the corn seeds in the lateral direction in the coating drum 11, so that the corn seeds close to the inner wall of the coating drum 11 can be dispersed and rolled, and then the corn seeds close to the inner wall of the coating drum 11 can be better adhered to the liquid medicine. At high speed, the height of the corn seeds in the coating drum 11 rising upward increases, thereby pushing the conical cover 148 to move upward. At this time, the upwardly moving conical cover 148 will pull the rotating rod 154 through the second connecting rod 155, so that the first telescopic rod 153 is extended, thereby increasing the area of ​​the triangular dispersion zone 150, which will cause the rotating rod 154, the first connecting rod 15, and the first telescopic rod 153 to move closer to the middle of the coating drum 11, thereby increasing the dispersion area of ​​the corn seeds in the lateral direction in the coating drum 11, and then When the rotating shaft 14 rotates at a high speed, the corn seeds with increased surge height can have a larger triangular dispersion area 150, so that the corn seeds have a better rolling effect, which is further convenient for mixing the liquid medicine with the corn seeds; secondly, when the rotating shaft 14 rotates at a high speed, the spiral blades 141 can more efficiently make the corn seeds in the coating drum 11 surge upward, which will increase the spacing between the corn seeds appropriately, and then when the rotating rod 154, the first connecting rod 15, and the first telescopic rod 153 extend toward the middle of the coating drum 11, the rotation of the rotating shaft 14 can be reduced. The impact force of the moving rod 154, the first connecting rod 15, and the first telescopic rod 153 prevents the corn seeds from being damaged by friction and also makes the coating effect better; and according to the set ball-head nozzle 161, the nozzle direction of the ball-head nozzle 161 can be automatically switched during the process of changing the area of ​​the triangular dispersion zone 150, so that the wind entering the coating drum 11 through the air inlet pipe 16 forms tangential wind, and the tangential wind can circulate upward in the coating drum 11, providing assistance to the rolling of the corn seeds, making the corn seeds roll more quickly and mixing with the liquid medicine better.

[0029] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
