DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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] See also Figures 1 to 7 The utility model provides a temperature regulating device for processing pesticide granules, including a regulating box 1 and a heater 2 connected to the regulating box 1. The heater 2 is a prior art and is used to heat the gas. When the temperature in the drying cylinder is too low, the temperature of the gas rises, and the opening of the air inlet 20 is also increased, and the air intake volume inside the drying cylinder is also increased. Under the condition of a constant gas flow rate, the temperature inside the drying cylinder continues to rise, which is conducive to the drying of the particles. The end of the regulating box 1 is provided with an air inlet 20, and the air inlet 20 is connected to a baffle 16 for shielding the air inlet 20. The baffle 16 is a rectangular parallelepiped structure. When the two baffles 16 are connected to each other, the air inlet 20 can be completely shielded. The baffle 16 is connected to a driving mechanism for driving the two baffles 16 to move closer to or away from each other. The driving mechanism includes a cylinder 4, a lifting rod 7, a lifting block 21, and two connecting plates 23. The cylinder 4 is used to drive the lifting rod 7 to move up and down. The lifting block 21 is used to guide the lifting rod 7. The two ends of the connecting plate 23 are connected to the lifting block 21 and the corresponding baffle 16. The adjustment box 1 is connected to a positioning mechanism for positioning the lifting rod 7.

[0025] Cylinder 14 can drive the lifting rod 7 to rise and fall, thereby driving the lifting block 21 to rise and fall, and then cooperate with the use of two connecting plates 23 to drive the two sliding blocks 14 located above to move closer to or farther away from each other, so as to facilitate the synchronous movement of the two baffles 16, closer to or farther away from each other, and to provide different sizes of shielding for the air inlet 20, thereby adjusting the air intake volume, facilitating the temperature adjustment in the drying cylinder (existing technology), so that it is within a suitable temperature range, thereby improving the material processing efficiency, and having strong practicality.

[0026] The driving mechanism also includes a frame 3 and a vertical slot 22. The frame 3 is connected to the top of the regulating box 1. The cylinder 14 is fixedly connected to the frame 3 to improve the stability of the cylinder 14. The power output end of the cylinder 14 is connected to the lifting rod 7. The vertical slot 22 is set in the regulating box 1. The lifting block 21 is slidably connected to the vertical slot 22, so that the lifting block 21 is lifted and lowered stably. When the lifting block 21 moves down, the lifting block 21 simultaneously applies thrust to the two connecting plates 23, the angle between the two connecting plates 23 gradually increases, and the connecting plates 23 push the corresponding baffles 16 to move, that is, the two baffles 16 move away from each other; when the lifting block 21 rises, the lifting block 21 simultaneously applies pulling force to the two connecting plates 23, the angle between the two connecting plates 23 gradually decreases, and the connecting plates 23 pull the corresponding baffles 16 to move, that is, the two baffles 16 move closer to each other.

[0027] Two slide grooves 13 and four sliding blocks 14 are arranged on the inner side of the regulating box 1. The two slide grooves 13 are arranged opposite to each other. The sliding blocks 14 are slidably connected to the corresponding slide grooves 13. The ends of the sliding blocks 14 are connected to the baffle 16. The two ends of the connecting plate 23 are connected to the sliding blocks 14 and the lifting blocks 21. When the baffle 16 moves, the sliding blocks 14 move on the corresponding slide grooves 13, which plays a good guiding role for the baffle 16 and moves steadily.

[0028] The lifting rod 7 passes through the top of the regulating box 1 , and the end of the lifting rod 7 is fixedly connected to the lifting block 21 .

[0029] The positioning mechanism includes a moving plate 5, a cylinder 2 6, and a positioning rod 9. The cylinder 2 6 is fixed to the top of the regulating box 1, and the power output end of the cylinder 2 6 is connected to the moving plate 5, and one end of the positioning rod 9 is connected to the moving plate 5. When the baffle 16 is in a suitable position, the cylinder 2 6 drives the moving plate 5 to move forward, driving the positioning rod 9 to move forward, so that the end of the positioning rod 9 is connected to the corresponding positioning groove 8, thereby locking the lifting rod 7 to prevent the lifting block 21 from moving, and then cooperate with the use of the connecting plate 23 and the sliding block 14 to achieve good positioning of the two baffles 16. At this time, the cylinder 1 4 can be stopped.

[0030] The lifting rod 7 is provided with a plurality of positioning grooves 8 , and the positioning grooves 8 match with the other end of the positioning rod 9 .

[0031] The movable plate 5 is connected with a clamping mechanism for clamping the baffle 16, and the clamping mechanism includes two connecting rods 10, two pressing cylinders 15, two pressing heads 17, two springs 18, and two guide posts 19. The two ends of the connecting rod 10 are connected to the movable plate 5 and the pressing cylinder 15. One end of the guide post 19 is inserted into the pressing cylinder 15, and the other end is connected to the pressing head 17. The spring 18 is sleeved on the guide post 19, and the two ends of the spring 18 are connected to the pressing head 17 and the pressing cylinder 15. When the end of the positioning rod 9 is connected to the corresponding positioning groove 8, the pressing head 17 is pressed against the corresponding baffle 16, the guide post 19 is further inserted into the pressing cylinder 15, and the spring 18 is in a compressed state, so as to achieve the clamping of the baffle 16, improve the tightness of the connection between the baffle 16 and the adjustment box 1, and at the same time play a certain limiting role on the adjustment box 1.

[0032] Two rectangular holes 12 are provided on the top of the regulating box 1. The movable plate 5 is slidably connected to the rectangular holes 12. A rubber pad 11 is connected inside the rectangular hole 12. The connecting rod 10 passes through the rubber pad 11. The connecting rod 10 and the rubber pad 11 are connected by an adhesive to improve the sealing of the connection between the two. The rectangular hole 12 guides the movable plate 5, so that the movable plate 5 moves steadily, prevents the positioning rod 9 from tilting and deviating, and facilitates docking with the corresponding positioning groove 8. The rubber pad 11 has good elasticity, which can prevent the internal gas of the regulating box 1 from being discharged from the rectangular hole 12, achieving a good isolation purpose. Secondly, it is also convenient for the connecting rod 10 to move, that is, when the connecting rod 10 is moving, the gas is not easy to leak.

[0033] The gas pipeline on the right side of the regulating box 1 is connected to the interface of the drying cylinder to convey hot air to the drying cylinder, thereby facilitating heating of the interior of the drying cylinder.

[0034] Working principle: When the temperature inside the drying cylinder needs to be adjusted, the cylinder 1 4 can drive the lifting rod 7 to rise and fall, and synchronously drive the lifting block 21 to rise and fall, and then cooperate with the use of two connecting plates 23 to make the two sliding blocks 14 located above move closer to or farther from each other synchronously, thereby realizing the two baffles 16 moving closer to or farther from each other, and being able to block the air inlet 20 of different sizes, thereby adjusting the air intake volume, facilitating the temperature adjustment inside the drying cylinder (existing technology), so that it is in a suitable temperature range, and facilitating the drying of particles. When the baffle 16 is in a suitable position, the cylinder 2 6 drives the moving plate 5 to move forward, and synchronously drives the positioning rod 9 and the two connecting rods 10 to move forward, until the end of the positioning rod 9 is connected to the corresponding positioning groove 8, the moving plate 5 stops moving, and the lifting rod 7 is locked, which can improve the stability of the two baffles 16. The forward movement of the two connecting rods 10 synchronously drives the pressing cylinder 15, the pressing head 17, the spring 18, and the guide column 19 to move forward, so that the pressing head 17 is pressed against the corresponding baffle 16, and the spring 18 is in a compressed state, thereby improving the tightness of the connection between the baffle 16 and the regulating box 1, and at the same time playing a certain limiting role on the regulating box 1, which is highly practical.
