Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a pesticide seed mixing device. Background Art

[0002] Pesticide seed mixing refers to mixing seeds and pesticides evenly before sowing, so that a layer of pesticide protective film is formed on the surface of the seeds, which can achieve the purpose of preventing and controlling pests and diseases. Pesticide seed mixing equipment is a special mechanical equipment used to mix pesticides with seeds.

[0003] At present, during the use of some seed mixing equipment, workers are required to hold the liquid pesticide and pour it into the seed mixing barrel. This not only makes it difficult for the liquid pesticide to contact the seeds quickly and evenly, but also there is a risk of the pesticide splashing and contacting the skin during the pouring process. This not only reduces the efficiency of seed mixing, but also increases the safety risks of workers.

[0004] At the same time, after some existing seed mixing equipment is completed, the seeds usually need to be laid out on an open ground, and then the pesticide liquid attached to the surface of the seeds is blown dry by natural wind. When the seeds are laid out for air drying, not only a large area is occupied, but also a lot of time and manpower are wasted. In addition, if the seeds are not air-dried in time, it is easy for the seeds to be stuck together by the pesticide liquid and form lumps. Utility Model Content

The number of nozzles 15 is several and they are distributed in an annular array at the center of the annular pipe 14. A support shell 11 is arranged in the inner cavity of the seed mixing barrel 1 and below the annular pipe 14. Connecting rods 12 are fixedly connected to both sides of the support shell 11, and one end of the connecting rod 12 is bolted to the inner wall of the seed mixing barrel 1. A linkage mechanism 9 is arranged in the inner cavity of the support shell 11. The linkage mechanism 9 is used in conjunction with the rotating shaft 3, and can drive the annular pipe 14 and the nozzle 15 to rotate in the opposite direction of the rotating shaft 3 when it rotates. A cartridge 6 is arranged on one side of the top of the top cover 18, and the cartridge 6 can inject the pesticide solution required for seed mixing. Temporary storage is performed, a scale window 19 is installed on the surface of the cartridge 6, the scale window 19 is made of transparent glass, and scale lines are attached to the surface of the scale window 19, which can measure and monitor the pesticide liquid level in the cartridge 6. A booster pump 7 is installed on the top of the seed mixing barrel 1 and below the cartridge 6. The liquid inlet of the booster pump 7 is connected to the cartridge 6. A connecting mechanism 8 is arranged at the center of the top cover 18. The connecting mechanism 8 is used in conjunction with the booster pump 7 to transport the pesticide liquid in the cartridge 6 to the inside of the annular pipe 14 and then spray it out from the nozzle 15. Based on this, the pesticide liquid can be evenly sprayed onto the surface of the seeds in the seed mixing barrel 1. By increasing the coverage rate of the pesticide liquid, the efficiency of pesticide seed mixing can be improved. An air pump 10 is installed on the other side of the top of the top cover 18. The air pump 10 is connected to the connecting mechanism 8. When used in combination, high-pressure airflow can be continuously input into the annular pipe 14, which can enable the nozzle 15 to spray high-speed airflow to perform wind drying on the seeds after mixing with medicine, and can also avoid the residual liquid medicine in the annular pipe 14, which may cause the nozzle 15 to be easily blocked. An exhaust mechanism 13 is arranged above the surface of the seed mixing barrel 1, and the exhaust mechanism 13 can draw the air inside the seed mixing barrel 1 to accelerate the air flow speed inside it, which can not only quickly discharge the moisture inside the seed mixing barrel 1, further improve the drying efficiency of the seeds after mixing with medicine, but also filter the odor of pesticides in the air, improve the comfort of the working environment, and reduce the harm to the operators. An observation window 17 is installed on the surface of the seed mixing barrel 1, and the observation window 17 is made of transparent glass.The staff can observe the mixing of seeds in the seed mixing barrel 1 in real time through the observation window 17. A discharge port 16 is provided below the surface of the seed mixing barrel 1, through which the seeds after the mixing can be discharged.

[0026] The linkage mechanism 9 includes a first bevel gear 91, which is located below the inner cavity of the support shell 11. The bottom end of the first bevel gear 91 passes through the connecting shaft to the bottom of the support shell 11 and is fixed to the through-hole through a bearing. The connecting shaft at the bottom of the first bevel gear 91 is bolted to the top of the rotating shaft 3. When the rotating shaft 3 rotates, it can drive the first bevel gear 91 to rotate synchronously. One side of the inner wall of the support shell 11 is rotatably connected with a second bevel gear 92 through a bearing seat. The second bevel gear 92 is meshed with the first bevel gear 91. One side of the second bevel gear 92 is meshed with a third bevel gear 93. The meshing action of 92 can make the first bevel gear 91 and the third bevel gear 93 rotate in opposite directions. The top end of the third bevel gear 93 passes through the connecting shaft to the top of the support shell 11 and is fixed to each other through a bearing. The connecting shaft at the top of the third bevel gear 93 is bolted with a cross 94. The four ends of the cross 94 are bolted to the surface of the annular pipe 14. When the rotating shaft 3 provides power, the meshing connection between the first bevel gear 91, the second bevel gear 92 and the third bevel gear 93 can make the cross 94 drive the annular pipe 14 and the nozzle 15 to rotate smoothly in the opposite direction to the rotating shaft 3.

[0027] The connecting mechanism 8 includes a three-way pipe 81, which is located at the center of the top cover 18. The three-way pipe 81 is a T-shaped pipe with an opening and closing valve. The flow of fluid or gas can be adjusted by controlling the closing of its valve. One end of the three-way pipe 81 is connected to the liquid outlet end of the booster pump 7 through a pipe, and the other end of the three-way pipe 81 is connected to the gas outlet end of the air pump 10 through a pipe. The bottom end of the three-way pipe 81 passes through the bottom of the top cover 18 and is fixed to the penetration point. The bottom end of the three-way pipe 81 is connected to a rotating joint 82, and the bottom end of the rotating joint 82 is connected to a cross pipe 83. The other end of the cross pipe 83 is connected to the annular pipe 14. When the annular pipe 14 rotates, the cross pipe 83 can adapt to the horizontal rotation angle change of the annular pipe 14 through the setting of the rotating joint 82. When the three-way pipe 81 is close to the valve on one side of the booster pump 7, the valve is opened. When the pressure is increased, the booster pump 7 can pump the pesticide liquid in the cartridge 6 to increase the pressure, and then discharge it to the inside of the annular pipe 14 through the three-way pipe 81, the rotary joint 82 and the cross pipe 83, and finally spray it out from the nozzle 15 to evenly cover the seeds in the seed mixing barrel 1, which helps to improve the uniformity and consistency of pesticide seed mixing, and can also save manpower and time costs to improve the efficiency of pesticide seed mixing. When the valve on the side of the three-way pipe 81 close to the air pump 10 is opened, the air pump 10 can input high-pressure airflow into the annular pipe 14, and the nozzle 15 can spray high-speed airflow to pneumatically dry the seeds after mixing, which can quickly remove the moisture in the pesticide liquid attached to the surface of the seeds, effectively reduce the situation where the seeds are adhered together due to the pesticide liquid during the seed mixing process, and can also pressurize the residual liquid in the annular pipe 14 to make it completely sprayed out, thereby reducing the blockage of the nozzle 15.

[0028] The exhaust mechanism 13 includes an exhaust shell 131, which is connected to the upper surface of the seed mixing barrel 1. An exhaust grille is provided on the side of the support shell 11 away from the seed mixing barrel 1. A filter screen 132 is installed on one side of the exhaust shell 131. The filter screen 132 can prevent seeds from accidentally entering the exhaust shell 131. An exhaust fan 133 is installed at the middle position of the exhaust shell 131 through a support rod. An activated carbon plate 134 is installed on the other side of the exhaust shell 131 through a support frame. When the exhaust fan 133 is running, the moisture inside the seed mixing barrel 1 can be pumped out to the exhaust fan 133. The outside of the exhaust shell 131 makes the air inside the seed mixing barrel 1 form a rapid flow effect, which can further improve the drying efficiency of the seeds after mixing, and in this process, the activated carbon plate 134 can also filter and adsorb the pesticide odor in the discharged moisture, which can improve the comfort of the working environment and reduce the harm to the operators. An open groove is opened on one side of the top of the exhaust shell 131, and the activated carbon plate 134 is of detachable design. The activated carbon plate 134 can be easily pulled out and replaced through the open groove of the exhaust shell 131, thereby ensuring the fluidity of the air and the filtering effect of the odor.

[0029] It is worth noting that the rotary joint 82 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0030] Working principle: first, the seeds to be mixed with medicine are put into the seed mixing cylinder 1 through the feeding hopper 2, and then the pesticide liquid required for mixing medicine is injected into the medicine cylinder 6, and then the driving motor 5 is started to drive the rotating shaft 3 and the spiral blade 4 to rotate to stir the seeds, and then the rotating shaft 3 drives the first bevel gear 91 to rotate, and through the setting of the second bevel gear 92, the horizontal pipe 83 can drive the annular pipe 14 and the nozzle 15 to rotate in the opposite direction of the liquid rotating shaft 3 through the cross 94. Next, the valve of the three-way pipe 81 is opened, and the booster pump 7 is started to pump the liquid in the medicine cylinder 6 through the connection of the three-way pipe 81, the rotary joint 82 and the horizontal pipe 83 to the annular pipe 14, and finally the nozzle 15 sprays the pesticide liquid to The surface of the seeds can improve the efficiency of pesticide seed mixing. When the seeds need to be dried after mixing, first open the valve on the side of the three-way pipe 81 close to the air pump 10, and then start the air pump 10 to allow the airflow to pass through the connecting mechanism 8 to input the airflow into the annular pipe 14, so that the nozzle 15 can spray high-speed airflow to dry the seeds after mixing, and can remove the moisture in the pesticide liquid attached to the surface of the seeds. At the same time, start the exhaust fan 133 to accelerate the discharge of humid air inside the seed mixing barrel 1, which can improve the drying efficiency of the seeds after mixing, and the activated carbon plate 134 can filter the odor of the pesticide. Finally, after the seeds after mixing are dried, the drive motor 5 can be turned off and the discharge port 16 can be opened to discharge the seeds.
