Description

Technical Field

[0001] This invention relates to the field of seed cotton de-cotton technology, and particularly to a seed cotton lint separating trial mill. Background Technology

[0002] The seed cotton ginning mill is mainly used after cotton is purchased to separate cotton fibers from cotton seeds by using a high-speed rotating saw-tooth hook.

[0003] Chinese patent CN218910605U discloses an integrated impurity-removing seed cotton lint separating and testing mill. An electronic weighing device is installed at the feed inlet, and seed cotton that meets the required quality enters the machine. Inside the machine, the seed cotton is fed slowly and at a uniform speed by the feeding rollers, while the spiked rollers open the seed cotton at high speed, exposing impurities. Under the action of the spiked rollers and partition grids, impurities such as cotton stalks, cotton leaves, and soil are separated using impact and centrifugal force. Under the action of the U-shaped toothed rollers, dust bars, and partition grids, cotton stalks, cotton leaves, soil, and other impurities, large impurities, and boll husks unique to machine-picked cotton, are separated. The opened and impurity-removed seed cotton enters the working box through the cotton passage. Under the action of the saw blade rollers, arc plates, and ribs, the cottonseed roll rotates in the working box, and the saw blade rollers hook out the cotton fibers, completing the separation of fibers and cottonseeds. The lint is thrown onto the dust cage rollers by the brush rollers, where it is compacted and discharged into the lint collection box.

[0004] During operation, the saw blade roller rotates, causing fibers to pass through the seed cotton comb assembly. When the saw blade roller carries too much fiber, it can cause blockage of the seed cotton comb assembly. Under forced separation, the seed cotton comb assembly is prone to deformation or even breakage. At the same time, as the saw blade roller operates for too long, it is prone to eccentricity or tooth deformation, causing friction between the saw teeth and the seed cotton comb assembly, further aggravating wear and increasing the probability of blockage. In addition, most existing equipment only achieves single-pass de-cottoning, and some residual fiber cotton seeds are directly discharged, requiring manual re-feeding of cotton seeds into the equipment for a second de-cottoning. Furthermore, as the operating time increases, the amount of fiber entanglement on the saw blade roller gradually increases, reducing de-cottoning efficiency.

[0005] Therefore, there is an urgent need in this field for a seed cotton lint separating and rolling mill that can fundamentally solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a seed cotton lint separating and ginning mill to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seed cotton ginning mill, including a frame, a drive mechanism and a seed cotton working box, and further including: a sawtooth cylinder assembly, one end of which is rotatably provided with a pulley that is connected to the drive mechanism for transmission, the pulley being connected to the sawtooth cylinder assembly for transmission through a clutch assembly;

[0010] Multiple cottonseed combs are arranged at equal intervals on a rotating shaft, and adjacent cottonseed combs are separated by spacers.

[0011] The “U”-shaped frame is fixedly installed on the outer wall of the seed cotton working box and located at the bottom of the rotating shaft;

[0012] A rotating component, which is sleeved on the end of the rotating shaft;

[0013] The contact element is slidably disposed within the "U"-shaped frame, and a pressure sensor is provided at its top, while an elastic reset element is provided between its bottom and the "U"-shaped frame.

[0014] A hydraulic component, one end of which is connected to an abutment and the other end to a clutch assembly, is capable of disengaging the clutch assembly.

[0015] Preferably, the cottonseed comb includes a fixed support portion, which is sleeved through the rotating shaft to support the cottonseed comb;

[0016] The primary cottonseed separator is arc-shaped and is fixedly installed on the top of the side wall of the fixed support. The top side wall is provided with an anti-clogging groove, which is used to prevent the saw toothed cylinder group from carrying away the cottonseeds when the cottonseed is removed.

[0017] The secondary cottonseed separator, shaped like an "S", is fixedly installed at the bottom of the side wall of the fixed support. It is used to perform secondary cottonseed removal after cotton removal and guide the cottonseed after secondary cotton removal to the cottonseed collection box.

[0018] Preferably, the cottonseed comb also includes an auxiliary cleaning section located in the middle of the secondary cottonseed separation section, which can clean the fibers wrapped around the sawtooth tube assembly.

[0019] Preferably, the sawtooth cylinder assembly includes a sawtooth shaft for driving the sawtooth cylinder assembly to rotate;

[0020] Multiple toothed discs are evenly spaced on the toothed shaft, and the toothed discs and cottonseed combs are staggered.

[0021] Multiple separators are evenly spaced and fitted onto the sawtooth shaft, and are staggered from the sawtooth disk;

[0022] Two turntables are mounted on both ends of the sawtooth shaft and are connected to the frame by bolts to fix the sawtooth cylinder assembly.

[0023] Preferably, the clutch assembly includes: a fixed tooth disposed on the side of the pulley near the frame;

[0024] The separating tooth is limited and slidably sleeved on the sawtooth shaft, and a sliding sleeve is provided on the side near the frame. An elastic element is provided between the sliding sleeve and the end of the sawtooth cylinder assembly.

[0025] The actuating element, whose limiting sleeve is located outside the sliding sleeve, is used to actuate the separating teeth to separate.

[0026] Preferably, it also includes an elastic plate, which is fixed inside the seed cotton working box, and is used to guide the cotton seeds after they have been separated by the primary cotton seed separation section to the secondary cotton seed separation section, so that the cotton seeds can be de-cottoned a second time.

[0027] Preferably, the rotating component includes: a collar sleeved on the end of the rotating shaft;

[0028] A semi-circular arc-shaped portion is provided on the side wall of the collar and near the toothed cylinder assembly. The semi-circular arc-shaped portion below the horizontal tangent at the bottom of the collar is cut off to form a notch.

[0029] Preferably, it also includes a cottonseed collection box, which is disposed at the bottom of the seed cotton comb assembly and is used to collect cottonseeds falling from the seed cotton comb assembly.

[0030] Preferably, the hydraulic assembly includes a first hydraulic telescopic member, which is disposed within a "U"-shaped frame, with one end fixedly connected to the inner wall of the "U"-shaped frame and the other end connected to an abutment member;

[0031] The second hydraulic telescopic component has its inner cavity connected to the first hydraulic telescopic component via an oil pipe. One end of the component is connected to the frame via a support frame, and the other end is connected to the clutch assembly.

[0032] The technical effects and advantages of this invention are as follows:

[0033] 1. This invention utilizes the cooperation between the seed cotton comb assembly, pulley, clutch assembly, and sawtooth cylinder assembly. When the seed cotton comb assembly is blocked, the increased resistance to the cotton comb causes the shaft to rotate, which in turn causes the pressure of the rotating component on the pressure sensor to exceed the threshold. Simultaneously, it squeezes the first hydraulic telescopic component, and the hydraulic oil inside the first hydraulic telescopic component will push the second hydraulic telescopic component to extend and retract. The extension and retraction of the second hydraulic telescopic component will push the clutch assembly to disengage, causing the sawtooth cylinder assembly to stop working. This avoids the situation where the cotton comb is damaged due to the sawtooth cylinder assembly forcibly working because of blockage.

[0034] 2. The present invention utilizes the cooperation between the seed cotton comb assembly, pulley, clutch assembly and sawtooth cylinder assembly, etc. When the seed cotton comb assembly is slightly blocked, the primary separation part of the cotton seeds and the rotating shaft rotate, causing the anti-blocking groove to deflect towards the sawtooth cylinder assembly. This allows the fibers to pass through when there is slight blockage, preventing more serious blockage.

[0035] 3. This invention utilizes the cooperation between the seed cotton comb assembly, pulley, clutch assembly, and sawtooth cylinder assembly. When it is necessary to detect the offset of the sawtooth cylinder assembly, the stepper motor is reversed. The reverse rotation of the shaft will drive the rotating parts and the seed cotton comb to reverse. The rotating parts always maintain contact with the contacting parts. When friction occurs between the seed cotton comb assembly and the sawtooth cylinder assembly, the resulting vibration will be transmitted to the seed cotton comb assembly, causing the pressure value detected by the pressure sensor to change frequently, thereby realizing the detection of the offset of the sawtooth cylinder assembly.

[0036] 4. This invention utilizes the cooperation between the seed cotton comb assembly, pulley, clutch assembly, and sawtooth cylinder assembly. When cleaning of the sawtooth cylinder assembly is required, the stepper motor is reversed. The reverse rotation of the stepper motor will cause the auxiliary cleaning part to come into contact with the separator on the sawtooth shaft, thereby cleaning the fibers that are wrapped around the separator due to the high-speed rotation of the sawtooth cylinder assembly during the production process, and avoiding the fibers wrapped around the separator from affecting the cotton removal efficiency.

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] like Figures 1 to 11 As shown, the seed cotton ginning mill includes a shell, a frame 1, a drive mechanism 2, and a seed cotton working box 3. It also includes a sawtooth cylinder assembly 4, one end of which is rotatably connected to a pulley 5 that is driven by the drive mechanism 2. The pulley 5 is connected to the sawtooth cylinder assembly 4 via a clutch assembly 7. This invention, by setting the clutch assembly 7, allows the seed cotton comb assembly 6 to drive and control the clutch assembly 7 to disengage when it becomes clogged, thereby protecting the clutch assembly 7. The shell is existing technology and will not be described further. The seed cotton working box 3 is detachably connected to the frame 1 for easy maintenance.

[0051] The seed cotton comb assembly 6 is rotatably mounted inside the seed cotton working box 3 and is driven to rotate by a stepper motor. It prevents cotton seeds from being carried away during the sawtooth cylinder assembly 4's cotton removal process, cleans the sawtooth cylinder assembly 4, disengages the clutch assembly 7 when the seed cotton comb assembly 6 becomes clogged, and detects the offset of the sawtooth cylinder assembly 4. This invention, by incorporating a stepper motor and controlling its operation, enables the adjustment of the seed cotton comb assembly 6.

[0052] The seed cotton comb assembly 6 includes a rotating shaft 601, which passes through the seed cotton working box 3 and is rotatably connected to the seed cotton working box 3. It is connected to the output shaft of a stepper motor. The present invention controls the operation of the stepper motor. The rotation of the stepper motor will drive the rotating shaft 601, and the rotation of the rotating shaft 601 will drive the cotton seed comb 602 to rotate, ultimately realizing the adjustment of the cotton seed comb 602.

[0053] Multiple cotton seed combs 602 are equally spaced and sleeved on the rotating shaft 601, and adjacent cotton seed combs 602 are separated by isolation blocks 603; by setting isolation blocks 603, the present invention can ensure that adjacent cotton seed combs 602 do not interfere with each other when rotating.

[0054] The “U”-shaped frame 604 is fixedly installed on the outer wall of the seed cotton working box 3 and located at the bottom of the rotating shaft 601. By setting the “U”-shaped frame 604, the present invention limits the contact member 607, so that the contact member 607 can slide up and down.

[0055] A rotating component 605 is sleeved on the end of the rotating shaft 601. By providing the rotating component 605, the invention achieves two objectives: First, when the seed cotton comb assembly 6 is clogged, the increased resistance to the seed cotton comb 602 causes the rotating shaft 601 to rotate, resulting in the rotating component 605 exerting pressure on the pressure sensor 608 exceeding a threshold. Simultaneously, it squeezes the hydraulic assembly, causing the hydraulic assembly to push the clutch assembly 7 to disengage, thus stopping the sawtooth cylinder assembly 4 from working. This prevents damage to the seed cotton comb 602 caused by the sawtooth cylinder assembly 4 forcibly operating due to blockage. Second, by controlling the stepper motor to reverse, the rotating shaft 601 reverses, causing the rotating component 605 and the seed cotton comb 602 to reverse as well. The rotating component 605 remains in contact with the contacting component 607. When friction occurs between the seed cotton comb assembly 6 and the sawtooth cylinder assembly 4, the resulting vibration is transmitted to the seed cotton comb assembly 6, causing the pressure value detected by the pressure sensor 608 to change frequently, thereby enabling the detection of the offset of the sawtooth cylinder assembly 4.

[0056] The contact member 607 is slidably disposed within the "U"-shaped frame 604, with a pressure sensor 608 at its top and an elastic reset member 609 between its bottom and the "U"-shaped frame 604. This invention uses the elastic reset member 609 to keep the contact member 607 in constant contact with the rotating member 605, facilitating pressure detection.

[0057] A hydraulic component, one end of which is connected to the contact member 607 and the other end of which is connected to the clutch assembly 7, is capable of disengaging the clutch assembly 7.

[0058] Specifically, the hydraulic assembly includes a first hydraulic telescopic member 610, which is disposed inside the "U"-shaped frame 604, with one end fixedly connected to the inner wall of the "U"-shaped frame 604 and the other end connected to the abutment member 607.

[0059] The second hydraulic telescopic member 611 has its inner cavity connected to the first hydraulic telescopic member 610 via an oil pipe. One end of the second hydraulic telescopic member 611 is connected to the frame 1 via a support frame 606, and the other end is connected to the actuating element 705 of the clutch assembly 7. When the first hydraulic telescopic member 610 is compressed, it will push the second hydraulic telescopic member 611 to extend, thereby pushing the clutch assembly 7 to disengage.

[0060] The cotton seed comb 602 includes a fixed support part 6021, which is sleeved through the rotating shaft 601 to support the cotton seed comb 602. The present invention achieves the fixation of the cotton seed comb 602 by setting the fixed support part 6021 so that the cotton seed comb 602 is sleeved with the rotating shaft 601.

[0061] The primary cottonseed separator 6022 is arc-shaped and is fixedly mounted on the top of the side wall of the fixed support 6021. An anti-clogging groove 6023 is provided on the top side wall of the separator to prevent the sawtooth tube assembly 4 from carrying away the cottonseeds during cotton removal. By setting the primary cottonseed separator 6022, the sawtooth tube assembly 4 drives the fibers through the gaps between the cottonseed combs 602, so that the primary cottonseed separator 6022 blocks the cottonseeds and prevents them from being carried away.

[0062] The secondary cottonseed separator 6024, shaped like an "S", is fixedly installed at the bottom of the peripheral side wall of the fixed support 6021. It is used to perform a second cottonseed removal process on the de-cottoned cotton, and simultaneously guides the de-cottoned cotton to the cottonseed collection box 9. By providing the secondary cottonseed separator 6024, the cottonseed after the first cottonseed removal process is guided by the secondary cottonseed separator 6024 and the elastic plate 8, causing the cottonseed to come into contact with the sawtooth cylinder assembly 4 again for a second cottonseed removal.

[0063] Furthermore, the cottonseed comb 602 also includes an auxiliary cleaning section 6025, which is located in the middle of the secondary cottonseed separation section 6024 and can clean the fibers wrapped on the sawtooth tube assembly 4. This invention controls the stepper motor to reverse a preset number of steps, causing the rotating shaft 601 to reverse, which in turn drives the rotating component 605 and the cottonseed comb 602 to reverse, ultimately causing the auxiliary cleaning section 6025 to come into contact with the separator 403 on the sawtooth tube assembly 4, thus cleaning the sawtooth tube assembly 4.

[0064] The sawtooth cylinder assembly 4 includes a sawtooth shaft 401, which is used to drive the sawtooth cylinder assembly 4 to rotate. In this invention, the belt pulley 5 drives the clutch assembly 7 to rotate, and the clutch assembly 7 drives the sawtooth shaft 401 to rotate. The rotation of the sawtooth shaft 401 will drive multiple sawtooth discs 402 and separators 403 to rotate synchronously.

[0065] Multiple toothed discs 402 are equally spaced and fitted onto the toothed shaft 401, and the toothed discs 402 and the cottonseed comb 602 are staggered.

[0066] Multiple separators 403 are equally spaced and sleeved on the sawtooth shaft 401, and are staggered with the sawtooth disk 402. The separators 403 of the present invention ensure that adjacent sawtooth disks 402 do not interfere with each other when they rotate, and the staggered distribution of the sawtooth disk 402 and the cottonseed comb 602 makes the cotton removal and combing process smoother.

[0067] Two turntables 404 are rotatably mounted on both ends of the sawtooth shaft 401 and are connected to the frame 1 by bolts, used to fix the sawtooth cylinder assembly 4. In this invention, the turntables 404 are fixed to the frame 1 by bolts, providing support and fixation for the sawtooth cylinder assembly 4.

[0068] The clutch assembly 7 includes a fixed tooth 701, which is disposed on the side of the pulley 5 near the frame 1.

[0069] The separating tooth 702 is limited and slidably sleeved on the sawtooth shaft 401, and a sliding sleeve 703 is provided on the side near the frame 1. An elastic element 704 is provided between the sliding sleeve 703 and the turntable 404 at the end of the sawtooth cylinder assembly 4.

[0070] A toggle element 705, which is limited and sleeved outside the sliding sleeve 703, is used to actuate the separation teeth 702. In this invention, when the hydraulic oil of the first hydraulic telescopic element 610 drives the second hydraulic telescopic element 611 to extend, the second hydraulic telescopic element 611 pushes the toggle element 705 to move. The movement of the toggle element 705 causes the sliding sleeve 703 to slide axially along the sawtooth shaft 401. The movement of the sliding sleeve 703 causes the separation teeth 702 to separate from the fixed teeth 701, and the sawtooth shaft 401 stops rotating.

[0071] It also includes an elastic plate 8, which is fixed inside the cotton seed working box 3. This plate guides the cotton seeds, after being separated by the primary cotton seed separator 6022, to the secondary cotton seed separator 6024, allowing for a second round of cotton seed removal. The elastic plate 8 is inclined and can be made of elastic rubber. The cotton seeds slide along the inclined direction of the elastic plate 8. The inclined structure of the elastic plate 8 accurately guides the cotton seeds to the secondary cotton seed separator 6024, enabling the cotton seeds to enter the secondary cotton seed separator 6024 for a second round of removal, ensuring thorough removal.

[0072] The rotating component 605 includes a collar 6051, which is sleeved on the end of the rotating shaft 601.

[0073] A semi-circular arc-shaped portion 6052 is provided on the circumferential side wall of the collar 6051 and near the serrated cylinder assembly 4. The semi-circular arc-shaped portion 6052 below the horizontal tangent at the bottom of the collar 6051 is cut off to form a notch; Figure 9 As can be seen, due to the notch design, the semi-circular arc portion 6052 is no longer a complete semi-circle. When the cottonseed comb 602 is clogged, and the shaft 601 rotates due to the clog, the shaft 601 drives the collar 6051 to rotate. The rotation of the collar 6051 will drive the semi-circular arc portion 6052 to rotate synchronously. When the arc portion of the semi-circular arc portion 6052 rotates to contact the contact member 607, it will push the contact member 607 to slide downward a certain distance, thereby compressing the first hydraulic telescopic member 610, which in turn can push the clutch assembly 7 to separate, preventing the cottonseed comb 602 from being damaged.

[0074] It also includes a cottonseed collection box 9, which is located at the bottom of the cotton seed comb assembly 6 and is used to collect cotton seeds falling from the cotton seed comb assembly 6. During operation, the cotton seeds, after being de-cottoned twice by the secondary separation section 6024 of the cotton seed comb assembly 6, slide down the structure of the cotton seed comb assembly 6 under the action of gravity. The guiding effect of the cotton seed comb assembly 6 ensures that the cotton seeds fall accurately into the cotton seed collection box 9 located at its bottom, where the cotton seed collection box 9 centrally collects and stores the cotton seeds.

[0075] During normal operation, the drive mechanism 2 drives the pulley 5 to rotate. The rotation of the pulley 5 drives the sawtooth shaft 401 to rotate through the clutch assembly 7. The rotation of the sawtooth shaft 401 drives the sawtooth disc 402 to rotate. The rotation of the sawtooth disc 402 pulls the fibers and passes them through the gap between the cotton seed combs 602 of the seed comb assembly 6. Under the action of the cotton seed combs 602, the cotton seeds are blocked, thereby achieving the separation of cotton seeds and fibers. The separated cotton seeds fall into the gap between the elastic plate 8 and the secondary separation part 6024 of the cotton seeds under the guidance of the seed comb assembly 6, so that the cotton seeds come into contact with the sawtooth disc 402 again for secondary de-cottoning.

[0076] When the sawtooth disc 402 carries too many fibers, causing blockage in the seed cotton comb assembly 6, the fibers cannot pass smoothly through the primary cotton seed separator 6022. This results in compression of the primary cotton seed separator 6022. After overcoming the elastic force of the elastic reset member 609, the primary cotton seed separator 6022 and the rotating shaft 601 will rotate. The rotation of the rotating shaft 601 will drive the rotating member 605 to rotate. The rotation of the rotating member 605 will generate a large squeezing force on the contact member 607, causing the pressure of the rotating member 605 on the pressure sensor 608 to exceed the threshold. At this time, a blockage alarm is triggered. Simultaneously, due to the cotton... The seed separation section 6022 and the rotating shaft 601 rotate, causing the anti-clogging groove 6023 to deflect toward the sawtooth cylinder assembly 4. In the event of slight blockage, the fibers can pass through, preventing more serious blockage. At the same time, the contact member 607 squeezes the first hydraulic telescopic member 610. The hydraulic oil in the first hydraulic telescopic member 610 will push the second hydraulic telescopic member 611 to extend. The extension of the second hydraulic telescopic member 611 will push the separation tooth 702 of the clutch assembly 7 to separate from the fixed tooth 701, causing the sawtooth cylinder assembly 4 to stop working. This avoids the situation where the cotton seed comb 602 is damaged due to the sawtooth cylinder assembly 4 forcibly working because of blockage.

[0077] When it is necessary to detect the offset of the sawtooth cylinder assembly 4, the stepper motor is controlled to rotate in the opposite direction to the sawtooth cylinder assembly 4, which is called reversal. The reversal of the stepper motor will drive the rotating shaft 601 to rotate in reverse, and the reversal of the rotating shaft 601 will drive the rotating part 605 and the cotton seed comb 602 to rotate in reverse. The rotating part 605 always keeps in contact with the contacting part 607. As the sawtooth cylinder assembly 4 rotates, if the offset of the sawtooth cylinder assembly 4 is too large, causing friction between the cotton seed comb assembly 6 and the sawtooth cylinder assembly 4, the vibration generated by the friction will be transmitted to the cotton seed comb assembly 6, thereby causing the pressure value detected by the pressure sensor 608 to change frequently. When the pressure value detected by the pressure sensor 608 changes frequently, the alarm will sound an alarm for excessive offset of the sawtooth cylinder assembly 4, thereby realizing the detection of the offset of the sawtooth cylinder assembly 4.

[0078] When it is necessary to clean the sawtooth cylinder assembly 4, the stepper motor is controlled to rotate in the opposite direction to the sawtooth cylinder assembly 4. This is called reversal. The reversal of the stepper motor will drive the rotating shaft 601 to reverse. The reversal of the rotating shaft 601 will drive the rotating part 605 and the cotton seed comb 602 to reverse. The reversal of the cotton seed comb 602 will drive the auxiliary cleaning part 6025 to fit with the separator 403 on the sawtooth shaft 401, thereby cleaning the fibers that are wrapped around the separator 403 due to the high-speed rotation of the sawtooth cylinder assembly 4 during the production process.

[0079] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
