Description

Technical Field

[0001] This invention relates to the field of seed cleaning technology, and in particular to a dust monitoring and control device for seed cleaning machinery based on a gas sensor. Background Technology

[0002] Seed cleaning is a crucial step in agricultural production and seed processing. Screening equipment selects plump, qualified seeds, improving seed quality and subsequent germination rates. However, during cleaning, most seeds carry some dust, which is easily dispersed by the vibration of the screen. This dust pollution can contaminate the work environment, and prolonged exposure can damage the respiratory health of workers, increasing the risk of occupational diseases. Furthermore, direct release of dust into the air can also cause air pollution in the surrounding environment.

[0003] Most existing seed cleaning machines only have cleaning functions and lack effective means of monitoring and controlling dust. Some cleaning machines are equipped with simple dust covers for dust prevention, but this method is difficult to sense dust concentration in real time and reduce dust in a targeted manner, and cannot fundamentally solve the problem of dust pollution. Therefore, a seed cleaning machine that can sense dust concentration and suppress dust is particularly important. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a dust monitoring and control device for seed cleaning machinery based on a gas sensor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust monitoring and control device for seed cleaning machinery based on a gas sensor includes a mounting frame on which a screen and a feeding box are connected. The feeding box is located above the screen. The device also includes: A dust cover is fixedly connected to the mounting frame and is located above the screen. A sensing element is fixedly connected to the inner wall of the dust cover. The air duct is fixedly connected to the mounting frame, and the air duct is connected to an exhaust pipe and an exhaust pipe. The end of the exhaust pipe away from the air duct is connected to the dust cover. The impeller blades are rotatably connected inside the air duct; A water tank is fixedly connected to the air duct, and a drain pipe is fixedly connected to the water tank. An atomizing nozzle is connected to the water outlet end of the drain pipe, and the atomizing nozzle faces the exhaust pipe.

[0006] Preferably, a first support frame is fixedly connected to the mounting bracket, and a drive rod is rotatably connected to the first support frame, the drive rod being fixedly connected to the impeller blade.

[0007] Furthermore, a pressure accumulator is fixedly connected to the mounting bracket, and a first gas supply pipe is fixedly connected to the pressure accumulator. The end of the first gas supply pipe away from the pressure accumulator is connected to the water tank.

[0008] Furthermore, a drive cylinder is fixedly connected to the mounting bracket, a sliding plug is slidably connected to the drive cylinder, and a second air supply pipe is fixedly connected to the side wall of the drive cylinder. The end of the second air supply pipe away from the drive cylinder is connected to the accumulator.

[0009] Furthermore, a cam is connected to the drive rod, and a pressing rod is slidably connected to the drive cylinder. The pressing rod and the slide plug are fixedly connected, and the end of the pressing rod away from the slide plug abuts against the cam.

[0010] Furthermore, a drive ball is fixedly connected to the end of the extrusion rod away from the slide plug, and the drive ball abuts against the cam.

[0011] Furthermore, a spring is fixedly connected to the slide, and the end of the spring away from the slide is fixedly connected to the inner top wall of the drive cylinder.

[0015] Compared with the prior art, the present invention provides a dust monitoring and control device for seed cleaning machinery based on gas sensors, which has the following beneficial effects: 1. This invention, through a sensor installed inside the dust cover, can monitor the dust concentration inside the dust cover in real time and accurately; when the concentration exceeds the standard, it can automatically trigger subsequent dust suppression treatment, realizing intelligent perception and response to dust generation.

[0016] 2. This invention utilizes an exhaust structure composed of a fan duct and impeller blades to quickly extract dust-laden air from the dust cover, reducing dust dispersion in the work area. Simultaneously, a pneumatic control system consisting of a cam, drive cylinder, and accumulator, in conjunction with a water tank and atomizing nozzles, converts gas pressure into atomized water flow, ensuring full contact between the atomized water and the dust-laden gas. This efficiently achieves dust settling and suppression, effectively improving dust control and reducing the harm of dust emissions to the environment and human health. Attached Figure Description

[0023] It should be noted that a one-way water supply pipe is connected to the side wall of water tank 3, which is used to replenish clean water into water tank 3.

[0024] Reference Figure 3 In practice, a solenoid valve is also installed on the first gas supply pipe 801, and the solenoid valve is electrically connected to the sensing part 401.

[0025] A drive cylinder 6 is fixedly connected to the mounting bracket 1. A sliding plug 605 is slidably connected in the drive cylinder 6. A second air supply pipe 601 is fixedly connected to the side wall of the drive cylinder 6. The end of the second air supply pipe 601 away from the drive cylinder 6 is connected to the accumulator 8.

[0026] A cam 7 is connected to the drive rod 701, and a pressing rod 604 is slidably connected to the drive cylinder 6. The pressing rod 604 and the slide plug 605 are fixedly connected, and the end of the pressing rod 604 away from the slide plug 605 abuts against the cam 7.

[0027] The end of the extrusion rod 604 away from the slide plug 605 is fixedly connected to a drive ball 6041, which abuts against the cam 7.

[0028] Reference Figure 5 , Figure 6 By setting a drive ball 6041 on the top of the extrusion rod 604, the cam 7 can stably extrude the extrusion rod 604, reducing the problem of the cam 7 and the extrusion rod 604 getting stuck and unable to rotate.

[0029] A spring 603 is fixedly connected to the slide 605, and the end of the spring 603 away from the slide 605 is fixedly connected to the inner top wall of the drive cylinder 6.

[0030] Reference Figure 5 The spring 603 provided on the slider 605 enables the slider 605 to be quickly reset.

[0031] An air supply pipe 602 is fixedly connected to the side wall of the drive cylinder 6, and a one-way valve 10 is provided on both the air supply pipe 602 and the second air supply pipe 601.

[0032] A second support frame 104 is fixedly connected to the mounting bracket 1. A rotating rod 9 is rotatably connected to the second support frame 104. A connecting wheel 901 is fixedly connected to the rotating rod 9. A first drive wheel 7011 is fixedly connected to the drive rod 701. The first drive wheel 7011 is connected to the connecting wheel 901 via a belt.

[0033] A drive motor 5 is fixedly connected to the mounting bracket 1. A second drive wheel 501 is fixedly connected to the drive end of the drive motor 5. The second drive wheel 501 is connected to the connecting wheel 901 via a belt.

[0034] Reference Figure 6 , Figure 7 The sensing unit 401 is electrically connected to the drive motor 5 via the controller, and the sensing unit 401 is a commercially available dust concentration sensor.

[0035] Reference Figures 1-3 During seed cleaning, the staff pours the seeds into the feeding box 101. The seeds in the feeding box 101 will slowly fall onto the screen 102. At this time, the seeds are screened by the inclined screen 102, and then plump and qualified seeds are screened out.

[0036] Reference Figures 2-7When the seeds are screened by the sieve 102, the dust carried by the seeds may be released. At this time, the sensing part 401 in the dust cover 4 will sense the dust concentration. When the dust concentration in the cover exceeds the standard, the sensing part 401 controls the drive motor 5 to start through the controller. The drive motor 5 will drive the connecting wheel 901 to rotate through the belt, which in turn drives the drive rod 701 to rotate. The rotation of the drive rod 701 will drive the impeller 203 to rotate. At this time, the air duct 2 will extract the dust in the dust cover 4 through the exhaust pipe 201. The extracted dust will be discharged through the exhaust pipe 202. When the drive rod 701 rotates, it will also drive the cam 7 to rotate. The rotation of the cam 7 will squeeze the drive compression rod 604 to slide, thereby pushing the slide plug 605 to slide in the drive cylinder 6. When the slide plug 605 slides down, the gas in the drive cylinder 6 will be discharged into the accumulator 8 through the second gas supply pipe 601 for storage.

[0037] When the sensing unit 401 controls the drive motor 5 to work through the controller, the sensing unit 401 will also control the solenoid valve on the accumulator 8 to open. At this time, the gas in the accumulator 8 will be transported to the water tank 3 through the first gas supply pipe 801. As the gas in the water tank 3 is transported, the pressure in the water tank 3 will increase. At this time, the water in the water tank 3 will be sprayed out through the drain pipe 301. Finally, after being atomized by the atomizing nozzle 3011, it will come into contact with the dust gas discharged from the bottom exhaust pipe 202, thereby effectively suppressing dust.
