Description

Technical Field

[0001] This utility model relates to the field of cotton seed processing technology, specifically a cotton seed processing and cleaning machine. Background Technology

[0002] A cotton seed processing and cleaning machine is a mechanical device used for cleaning cotton seeds. It mainly consists of a screening device, an air separation device, an electrical control device, and a support device. Its main function is to separate seeds and impurities through aerodynamic characteristics, ensuring the quality and purity of the seeds. This equipment is widely used in agricultural production and scientific research experiments. It has the characteristics of small footprint, simple operation, and high processing precision. With the continuous production of cleaning machines, various cleaning equipment has emerged, such as a cotton seed processing and cleaning machine.

[0003] A search revealed a cotton seed processing and cleaning machine in patent number CN202122329442.9. The machine includes a cleaning chamber, a feeding port, and a feeding area. A feeding mechanism is installed above the cleaning chamber, and a feeding port is located above the feeding mechanism. An air separation mechanism is located on one side of the cleaning chamber, and a screening mechanism is located below inside the cleaning chamber. A mounting base is installed above a mounting plate, and a cam is mounted on one end of the mounting base. A connecting rod is installed between the cams, and a second servo motor is mounted on the other end of the mounting base. One end of the second servo motor is connected to one end of the cam. This invention incorporates a screening mechanism inside the cleaning chamber, utilizing the sieve plate and extension... The coordinated operation of the compression spring, mounting plate, mounting base, cam, connecting rod, and second servo motor enables efficient screening of cotton seeds, separating some waste from the seeds. However, while the equipment can efficiently screen cotton seeds and separate some waste from the seeds, the air separation mechanism cannot completely remove all dust from the cotton seeds through the discharge port into the first storage chamber. Some dust remains inside the chamber and re-adheres to the outside of the cotton seeds, resulting in poor cleaning performance over long-term use. Therefore, a cotton seed processing and cleaning machine with a high dust removal rate is proposed, which can continuously clean the dust inside the moving cylinder until it is completely removed before continuing to screen for large particles. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cotton seed processing and cleaning machine that can continuously clean dust inside the moving drum until all dust is removed before continuing to screen large particles, achieving a high dust removal rate. This solves the problem in the air separation mechanism of the device in patent number CN202122329442.9, where not all dust reaches the first storage chamber from the discharge port during the process of blowing away dust from the outside of the cotton seeds, leaving some dust inside the chamber and causing it to re-adhere to the outside of the cotton seeds, resulting in poor cleaning effect over long-term use.

[0005] To achieve the above-mentioned goal of continuously cleaning the inside of the moving drum until the dust is completely removed before continuing to screen large particles with a high dust removal rate, this utility model provides the following technical solution: a cotton seed processing cleaning machine, including a cleaning machine body, a feed hopper fixedly installed on the outside of the cleaning machine body, and a cleaning mechanism provided inside the cleaning machine body;

[0006] The cleaning mechanism includes a feed pipe, an air-separating drum, dust-raising plates, a fan, an electric telescopic rod, a discharge pipe, a screening cylinder, a servo motor, and gears. The feed pipe is fixedly installed at the bottom of the feed hopper. An air-separating drum is installed inside the cleaning machine body. Several dust-raising plates are fixedly installed inside the air-separating drum. A fan is fixedly installed inside the cleaning machine body. An electric telescopic rod is fixedly installed inside the cleaning machine body. A discharge pipe is fixedly installed inside the cleaning machine body. A screening cylinder is installed inside the cleaning machine body. A servo motor is fixedly installed inside the cleaning machine body, and gears are installed at the output end of the servo motor.

[0007] Furthermore, a dust detector is fixedly installed at the bottom of the feed pipe, and an exhaust pipe adapted to the air classifier drum is provided on the outside of the cleaning machine body. By setting the dust detector, the dust concentration inside the air classifier drum can be detected in real time.

[0008] Furthermore, a filter screen is provided on the outside of the screening cylinder, which allows cotton seeds to fall and large particles of debris to be filtered out.

[0009] Furthermore, an external gear ring is fixedly installed on the outside of the air classifier drum, and the external gear ring meshes with a gear. A support pulley assembly adapted to the air classifier drum is fixedly installed inside the cleaning machine body. By setting the support pulley assembly, the air classifier drum can rotate normally.

[0010] Furthermore, the cleaning machine body is equipped with a collection box and a waste box inside. The collection box is located at the bottom of the filter screen, and the collection box is beneficial for collecting cotton seeds.

[0011] Furthermore, a sealing plate is fixedly installed on the right side of the electric telescopic rod. The sealing plate has an arc-shaped groove inside that matches the air separator roller. By setting the sealing plate, it is beneficial to prevent cotton seeds from falling off.

[0012] Furthermore, an external gear ring two is fixedly installed on the outside of the screening cylinder and meshes with a gear, and a support pulley assembly two adapted to the screening cylinder is fixedly installed inside the cleaning machine body. By setting the support pulley assembly two, the screening cylinder can rotate normally.

[0013] Furthermore, a PLC controller is installed at the front of the cleaning machine body, and the fan, electric telescopic rod, servo motor and duct dust detector are all electrically connected to the PLC controller through wires.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This cotton seed processing and cleaning machine, through the setting of a cleaning mechanism, allows cotton seeds to be put into the feed hopper when cleaning is required. The PLC controller is then activated, which in turn starts the fan and servo motor. The cotton seeds enter the air-separating drum through the feed pipe. As the air-separating drum rotates, several dust-raising plates lift the seeds and they fall. The fan continuously blows the dust towards the exhaust pipe until the dust detector in the air duct detects that the dust has reached a suitable range. Then, the PLC controller activates the electric telescopic rod to retract, and the seeds fall into the screening cylinder through the discharge pipe. The seeds then fall into the collection box through the filter screen, while large particles fall into the waste box. This cleaning mechanism can continuously clean the dust inside the moving cylinder until the dust is completely removed before continuing to screen large particles, resulting in a high dust removal rate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The cotton seed processing and cleaning machine in this embodiment includes a cleaning machine body 1, a feed hopper 2 fixedly installed on the outside of the cleaning machine body 1, and a cleaning mechanism 3 provided inside the cleaning machine body 1;

[0024] The cleaning mechanism 3 includes a feed pipe 301, an air-separating drum 302, a dust-raising plate 303, a fan 304, an electric telescopic rod 305, a discharge pipe 306, a screening cylinder 307, a servo motor 308, and a gear 309. The feed pipe 301 is fixedly installed at the bottom of the feed hopper 2. The air-separating drum 302 is installed inside the cleaning machine body 1. Several dust-raising plates 303 are fixedly installed inside the air-separating drum 302. The fan 304 is fixedly installed inside the cleaning machine body 1. The electric telescopic rod 305 is fixedly installed inside the cleaning machine body 1. The discharge pipe 306 is fixedly installed inside the cleaning machine body 1. The screening cylinder 307 is installed inside the cleaning machine body 1. The servo motor 308 is fixedly installed inside the cleaning machine body 1. The output end of the servo motor 308 is equipped with a gear 309.

[0025] In the implementation of the case, a dust detector 4 is fixedly installed at the bottom of the feed pipe 301. An exhaust pipe 5 adapted to the air classifier drum 302 is set on the outside of the cleaning machine body 1. By setting the dust detector 4, the dust concentration inside the air classifier drum 302 can be detected in real time. An electrostatic induction probe is set inside the dust detector 4. The electrostatic induction probe captures the charged characteristics of particles, thereby detecting the dust concentration in the air duct. When the concentration is low, the sensor signal is connected to the PLC controller 14, which causes the PLC controller 14 to start other components.

[0026] In the implementation of the case, a filter screen 6 is provided on the outside of the screening cylinder 307. By setting the filter screen 6, cotton seeds can fall and large particles of impurities can be filtered out. The aperture of the filter screen 6 is six millimeters. The size of cotton seeds is usually between three and four millimeters, so large particles of impurities are filtered out by the filter screen 6. The tilt angle of the air classifier 302 is fifteen degrees and the tilt angle of the screening cylinder 307 is five degrees.

[0027] In the implementation of the case, an external gear ring 7 is fixedly installed on the outside of the air classifier drum 302, and the external gear ring 7 meshes with the gear 309. A support pulley assembly 8 adapted to the air classifier drum 302 is fixedly installed inside the cleaning machine body 1. An external gear ring 12 is fixedly installed on the outside of the screening cylinder 307 and meshes with the gear 309. A support pulley assembly 13 adapted to the screening cylinder 307 is fixedly installed inside the cleaning machine body 1. By setting the external gear ring 7 and the external gear ring 12, the servo motor 308 can rotate and then rotate the air classifier drum 302 and the screening cylinder 307 by meshing the external gear ring 7 and the external gear ring 12.

[0028] In the implementation of this case, the PLC controller 14 is electrically connected to all electronic components in this patent via wires, thereby controlling all electronic components in this patent by operating the PLC controller 14.

[0029] When implementing this procedure, please follow these steps:

[0030] 1) When cotton seeds need to be cleaned, put the cotton seeds into the feed hopper 2 and turn on the PLC controller 14;

[0031] 2) Then the fan 304 and servo motor 308 are turned on, and the cotton seeds enter the air classifier drum 302 from the feed pipe 301. When the air classifier drum 302 rotates, several dust-raising plates 303 lift the seeds and then drop them.

[0032] 3) The blower 304 continuously blows the dust toward the exhaust pipe 5 until the dust detector 4 detects that the dust has reached a suitable range, and then the PLC controller 14 activates the electric telescopic rod 305 to retract.

[0033] 4) Finally, the seeds fall into the screening cylinder 307 through the feeding pipe 306, and then fall into the collection box 9 through the filter screen 6. Large particles of debris fall into the waste box 10.

[0034] In summary, this cotton seed processing and cleaning machine, through the setting of cleaning mechanism 3, allows cotton seeds to be put into the feed hopper 2 when cotton seed cleaning is required. The PLC controller 14 is then turned on, which causes the fan 304 and servo motor 308 to start. The cotton seeds enter the air classifier drum 302 from the feed pipe 301. When the air classifier drum 302 rotates, several dust-raising plates 303 lift the seeds and they fall. The fan 304 continuously blows the dust towards the exhaust pipe 5 until the dust detector 4 detects that the dust has reached a suitable range. Then, the PLC controller 14 activates the electric telescopic rod 305 to retract, and the seeds fall into the screening cylinder 307 through the discharge pipe 306. The seeds then fall into the collection box 9 through the filter screen 6, while large particles fall into the waste box 10. This cleaning mechanism 3 can continuously clean the dust inside the moving cylinder until the dust is completely removed before continuing to screen large particles, resulting in a high dust removal rate.
