Description

Technical Field

[0001] This invention belongs to the field of cotton harvesting, specifically relating to an automatic cotton harvesting, cleaning, and baling integrated machine. Background Technology

[0002] With the continuous advancement of agricultural mechanization, mechanized cotton harvesting has become the mainstream cotton harvesting method. However, compared with manual harvesting, mechanized cotton harvesting has a higher impurity rate, generally 12%-20%, mainly consisting of small branches, broken cotton leaves, and seed hulls. After mechanical harvesting and compression, the seed cotton enters the cotton processing plant. Due to the high impurity rate, a special seed cotton cleaning machine is used to further remove impurities. However, the compression and packaging increase the adhesion between impurities such as cotton leaves, stalks, and boll hulls and cotton fibers, making subsequent cleaning more difficult. This not only results in low cleaning efficiency, but also is time-consuming, labor-intensive, and extremely costly. Therefore, from the time the seed cotton is harvested until before baling, impurity removal should be carried out on the seed cotton to reduce the impurity rate.

[0003] A search of existing technologies revealed relevant patents. One Chinese utility model patent, patent number 202321892082.6, entitled "A cotton harvester equipped with a seed cotton impurity removal device," describes a method that uses a primary impurity removal device installed at the top inside the cotton collection box, and a secondary impurity removal device installed below the cotton conveyor belt. Both the primary and secondary devices utilize the negative pressure of a removal fan to collect impurities, thus reducing the impurity content of the seed cotton. While this method can reduce the impurity content of the seed cotton to some extent, its effectiveness is limited; impurities on the surface of the seed cotton clumps can be collected, but impurities inside the clumps cannot. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cotton picking, cleaning and baling integrated machine. By designing a cleanup device in the integrated machine, the problem of high impurity content in seed cotton during the round mold baling process after harvesting is solved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic cotton picking, cleaning, and baling integrated machine includes a chassis, a cotton picking head connected to the front end of the chassis via a suspension device, a cotton conveying channel installed on the chassis and connected to the cotton picking head, and a cotton conveying fan connected to the cotton conveying fan. The negative pressure generated by the cotton conveying fan transports the seed cotton picked by the cotton picking head to a cotton collection box. The machine is characterized by a spiked roller arranged at the outlet of the cotton conveying channel that can rotate on a fixed axis, and a filter device installed below the spiked roller. A primary impurity removal device is installed at the top of the cotton collection box, and multiple secondary impurity removal devices are arranged obliquely inside the cotton collection box. A cotton discharge roller is installed above the secondary impurity removal devices and can rotate on a fixed axis to force cotton discharge. A cotton conveying belt assembly is located at the front end of the bottom of the baling bin, a tertiary impurity removal device is installed below the cotton conveying belt assembly, and a cotton support frame is installed at the rear of the baling bin.

[0007] As a further technical solution, the primary impurity removal device consists of an impurity removal fan and an arc-shaped filter plate. The impurity removal fan is arranged and installed on the top of the cotton collection box along the width direction of the cotton harvester, and each impurity removal fan corresponds to one of the cotton conveying channels. The arc-shaped filter plate is evenly distributed with small holes.

[0008] As a further technical solution, the upper surface of the filter device is evenly distributed with small holes, and the inner bottom surface of the filter device is inclined.

[0009] As a further technical solution, the secondary impurity removal device consists of a screen, a screen frame, a vibrator, a base, shock-absorbing springs, a rotating shaft, and a pressure sensor. The screen is fixedly installed on the upper surface of the screen frame, and the vibrator is fixedly installed on the lower surface of the screen frame, one on each side. The screen frame and the base are connected by shock-absorbing springs. Both the lower surface of the screen frame and the bottom surface of the base have small cylindrical protrusions to provide positions for the fixed installation of the shock-absorbing springs. The rotating shaft is fixedly installed on one side of the base, and the rotating shaft is mounted on the side walls of the cotton harvester via bearings, enabling the secondary impurity removal device to rotate on a fixed axis. The pressure sensor is fixedly installed inside the secondary impurity removal device to detect the pressure exerted by the screen on the seed cotton.

[0010] As a further technical solution, the rotating shafts of the multiple secondary impurity removal devices are driven by the same motor, and the motor drives the rotating shafts of the multiple secondary impurity removal devices simultaneously through a gear transmission device.

[0011] As a further technical solution, the bottom surface of the substrate is inclined inward, so that impurities can be gathered in one place.

[0012] As a further technical solution, the impurities collected by the filtration device and the secondary impurity removal device are connected by a flexible hose and directly discharged from the machine body.

[0013] As a further technical solution, the opening rollers are dispersedly installed at the bottom of the cotton collection box, and the cotton conveying belt is composed of filter mesh. The seed cotton loosened by the opening rollers falls onto the cotton conveying belt assembly.

[0014] As a further technical solution, the packaging device mainly consists of a first drive roller, a second drive roller, a rocker arm, a rocker arm cylinder, a packing strap, and multiple rollers. Under the drive of the first drive roller and the second drive roller, the packing strap is wound around each roller and rotates in a cycle. The rocker arm cylinder drives the rocker arm to rotate counterclockwise or clockwise.

[0015] As a further technical solution, the cotton support frame is installed at the rear of the packing bin, and the two fulcrums of the cotton support frame are respectively rotatably mounted on the chassis and the telescopic hydraulic cylinder rotatably mounted on the chassis.

[0016] The beneficial effects of this invention are as follows:

[0017] The automatic cotton picking, cleaning, and baling integrated machine proposed in this invention achieves automatic cotton picking, cleaning, and baling through the coordinated operation of the cotton picking head, cotton conveying channel, cotton collection box, impurity removal device, baling device, and cotton support frame. During the impurity removal process, a three-stage impurity removal system is employed. First, a primary impurity removal device positioned above the cotton collection box uses a fan to create suction to collect impurities, which are then blocked by an arc-shaped filter plate, effectively removing surface impurities from the cotton and discharging them outside the machine, thus initially reducing the impurity content of the cotton. Next, the squeezing and kneading action of the spiked rollers causes impurities inside the cotton to be turned to the surface. A secondary impurity removal device is installed inside the cotton collection box, further cleaning impurities under vibration. Simultaneously, the secondary impurity removal device is inclined inside the cotton collection box, causing the cotton flow within the box to be S-shaped, increasing the impurity removal path and ensuring more thorough cleaning. The cotton harvester utilizes a forced cotton discharge roller and a pressure sensor to detect any blockages in the cotton collection box. If blockage occurs, the tilt angle of the secondary impurity removal device is automatically adjusted to accelerate cotton flow. The stepper motor is controlled by the harvester's own controller, eliminating the need for an external controller. After passing through the primary and secondary impurity removal devices, a tertiary impurity removal device further cleans up any remaining impurities, resulting in more thorough removal, reduced impurity content in the cotton, increased cotton utilization, and significant savings in time and manpower for cleaning, thus lowering costs and facilitating subsequent cotton processing and application. The integrated cotton harvesting, cleaning, and packaging system, combined with the control system, enables fully automated operation. Attached Figure Description

Detailed Implementation

[0027] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, the present invention proposes an automatic cotton picking, cleaning and packaging integrated machine.

[0030] In a typical embodiment of the present invention, such as Figure 1 As shown in the accompanying drawings, embodiments of the present invention will be described below. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figures 1-6 As shown in this embodiment, an automatic cotton picking, cleaning, and baling integrated machine includes: a chassis 5, a suspension device 2, a cotton picking head 1, a driver's cab 3, a cotton conveying channel 4, a cotton conveying fan 7, a spiked roller 17, a filter device 19, a primary impurity removal device 16, a cotton collection box 18, a secondary impurity removal device 20, a cotton discharge roller 15, an opening roller 6, a cotton conveying belt assembly 8, a tertiary impurity removal device 9, a baling bin 12, and a cotton support frame 11. The connection relationship between each component is as follows: the cotton picking head 1 is connected to the front end of the chassis 5 through the suspension device 2; the cotton conveying channel 4 is installed on the chassis 5 and connected to the cotton picking head 1; the cotton conveying channel 4 is connected to the cotton conveying fan 7; the negative pressure generated by the cotton conveying fan 7 transports the seed cotton picked by the cotton picking head to the cotton collection box 18; the spiked roller 17 is arranged in the cotton conveying channel 4. The outlet can rotate on a fixed axis, and the filter device 19 is installed below the spiked roller; the primary impurity removal device 16 is installed on the top of the cotton collection box, and a secondary impurity removal device 20 is provided inside the cotton collection box. Multiple secondary impurity removal devices 20 are arranged obliquely inside the cotton collection box, and the cotton discharge roller is installed above the secondary impurity removal device and can rotate on a fixed axis to force cotton discharge; the cotton conveying belt assembly is located at the front end of the bottom of the packing bin 12, the tertiary impurity removal device 9 is installed below the cotton conveying belt assembly 8, and the cotton support frame 11 is installed at the rear of the packing bin; the present invention, through the ingenious combination of the primary impurity removal device, the secondary impurity removal device and the tertiary impurity removal device, fundamentally reduces the impurity content of seed cotton, saves a lot of time and manpower for subsequent seed cotton cleaning, reduces costs, and is beneficial to the subsequent processing and application of seed cotton.

[0032] Specifically, the cotton picking head 1 is installed at the front end of the chassis 5 through the suspension device 2. The height between the cotton picking head 1 and the ground surface can be adjusted through the suspension device 2, which can protect the picking parts and reduce the missed picking rate.

[0033] The cotton conveying channel 4 is installed on the chassis 5 and connected to the cotton picking head 1. The cotton conveying channel 4 is connected to the cotton conveying fan 7. The negative pressure generated by the cotton conveying fan 7 transports the seed cotton picked by the cotton picking head 1 to the cotton collection box 18.

[0034] The spiked roller 17 is arranged at the outlet of the cotton conveying channel 4. The spiked roller 17 can rotate on a fixed axis. The filter device 19 is installed below the spiked roller 17. The main function of the spiked roller 17 is to squeeze and rub the seed cotton. The upper surface of the filter device 19 is evenly distributed with small holes, which can filter impurities and prevent seed cotton from entering. The bottom surface of the filter device 19 is inclined so that the impurities entering the filter device 19 can be collected in one place and easily discharged.

[0035] Furthermore, the primary impurity removal device 16 consists of an impurity removal fan 162 and an arc-shaped filter plate 161. The impurity removal fan 162 is arranged and installed on the top of the cotton collection box 18 along the width direction of the cotton harvester, and each impurity removal fan 162 corresponds to a cotton conveying channel 4. Before the seed cotton sent from the cotton conveying channel 4 falls into the cotton collection box 18, it will be squeezed and rubbed by the spiked roller 17. Impurities on the upper side of the seed cotton will be sucked into the impurity removal fan 162 through the arc-shaped filter plate 161 due to the negative pressure suction of the impurity removal fan 162, and then collected or directly discharged from the machine body. Impurities on the lower side of the seed cotton will fall into the impurity filtering device 19, thereby separating the impurities from the seed cotton.

[0036] Furthermore, the arc-shaped filter plate 161 is evenly distributed with small holes, which can be of any shape. Impurities in the seed cotton can pass through, while the seed cotton will be blocked. Finally, the seed cotton will fall into the cotton collection box due to gravity, thus playing the role of removing impurities.

[0037] Furthermore, the secondary impurity removal device 20 is inclinedly arranged inside the cotton collection box 18, so that the flow of seed cotton in the cotton collection box 18 is S-shaped to increase the impurity removal path. The cotton discharge roller 15 is installed above the secondary impurity removal device 20 and can rotate on a fixed axis to force cotton discharge, preventing seed cotton from clogging inside the cotton collection box 18. In this embodiment, in order to make the flow of seed cotton in the cotton collection box 18 S-shaped, the secondary impurity removal device 20 includes three devices. The three secondary impurity removal devices 20 are alternately inclined on the inner wall of the cotton collection box 18. Of course, it is easy to understand that four, five, etc. can also be set, depending on the needs.

[0038] Specifically, such as Figure 2 , Figure 3As shown, each secondary impurity removal device 20 in this embodiment consists of a screen 207, a screen frame 204, a vibrator 205, a base 201, shock-absorbing springs 203, a rotating shaft 202, and a pressure sensor 206. The screen 207 has evenly distributed small holes and can be of any shape. It is fixedly installed on the upper surface of the screen frame 204. The vibrator 205 is fixedly installed on the lower surface of the screen frame 204, one on each side. The vibrator 204 can be a vibrating motor or a vibrating electric motor. The screen frame 204 and the base 201 are connected by four shock-absorbing springs 203. The lower surface of the screen frame 204 and the bottom surface of the base 201 both have small cylindrical protrusions to provide positions for the fixed installation of the shock-absorbing springs 203. A rotating shaft 202 is fixedly installed on one side of the base 201. The rotating shaft 202 is fixedly installed on the box walls on both sides of the cotton harvester through bearings, which can drive the secondary impurity removal device 20 to achieve fixed-axis rotation. The bottom surface of the base 201 is inclined so that impurities can be collected in one place for easy discharge. Impurities collected by the secondary impurity removal device 20 are discharged directly from the machine body through a discharge hose 21. A pressure sensor 206 is fixedly installed inside the secondary impurity removal device 20 to detect the pressure between the screen 207 and the seed cotton, ensuring that the seed cotton in the cotton collection box 18 is not blocked.

[0039] Furthermore, in order to adjust the tilt angle of the secondary impurity removal device 20, a gear is connected to the end of the rotating shaft 202 of the secondary impurity removal device 20. Through gear transmission, the power of the stepper motor is distributed to each secondary impurity removal device 20. When the pressure detected by the pressure sensor 206 is too high, the stepper motor starts and rotates forward, increasing the tilt angle of the secondary impurity removal device 20 so that the seed cotton can flow faster in the cotton collection box 18. When the pressure detected by the pressure sensor 206 returns to normal, the stepper motor starts and reverses to the initial position until the pressure detected by the pressure sensor 206 is too high again. The control of the stepper motor is realized by the controller of the cotton harvester itself.

[0040] like Figure 3 As shown, the three secondary impurity removal devices 20 in this embodiment are driven by the same stepper motor. Specifically, the stepper motor shaft transmits power to the stepper motor shaft output gear through a coupling, and then transmits it to the first transmission gear, the second transmission gear, and the third transmission gear through gear meshing. The three transmission gears correspond to the rotating shafts 202 of the three secondary impurity removal devices 20. Since the rotation direction of the second transmission gear needs to be opposite to that of the first and third transmission gears, an idler gear needs to be installed to change the rotation direction.

[0041] Furthermore, the opening rollers 6 are dispersedly installed at the bottom of the cotton collection box 18. Before the seed cotton is fed into the cotton conveyor belt assembly 8, the opening rollers 6 can loosen the compressed and tangled seed cotton, which plays a rubbing role on the cotton. The impurities inside the seed cotton ball will come to the outside of the seed cotton ball, which is in preparation for the third-stage impurity removal.

[0042] Furthermore, the cotton conveyor belt assembly 8 is located at the front end of the bottom of the packing bin 12. It includes a cotton conveyor belt composed of a filter mesh. The seed cotton, after being loosened by the opening roller 6, falls onto the cotton conveyor belt assembly 8.

[0043] Furthermore, a three-stage impurity removal device 9 is installed below the cotton conveyor belt assembly 8. The three-stage impurity removal device 9 consists of an impurity removal fan 91, an impurity discharge trough 92, and an impurity discharge pipe 93. When seed cotton falls onto the cotton conveyor belt assembly 8 and begins to be fed from front to back, the impurity removal fan 91 starts to form a negative pressure suction. Impurities that have not been removed by the first-stage impurity removal device 16 and the second-stage impurity removal device 20 pass through the filter mesh structure of the cotton conveyor belt, are sucked into the air inlet of the impurity removal fan 91, and are discharged through the air outlet. The bottom of the impurity discharge trough 92 of the three-stage impurity removal device 9 is designed with an inclined structure, and the lowest point is connected to the impurity discharge pipe 93. Impurities discharged through the air outlet are discharged out of the machine body through the impurity discharge pipe 93.

[0044] Furthermore, the impurity removal fan 162 of the primary impurity removal device 16 has the same structure as the impurity removal fan 91 of the tertiary impurity removal device 9.

[0045] Furthermore, the cotton conveyor belt assembly 8 continuously feeds the cleaned seed cotton into the baling device 14 in the baling bin 12 to bale the seed cotton.

[0046] Furthermore, the baling device 14 in this embodiment mainly consists of a first drive roller 141, a second drive roller 145, a rocker arm 144, a rocker arm cylinder 143, a baling strap 142, and multiple rollers. The first drive roller 141, the second drive roller 145, the rocker arm 144, the rocker arm cylinder 143, the baling strap 142, and multiple rollers are all installed in the baling chamber. Driven by the first drive roller 141 and the second drive roller 145, the baling strap 142 is wound around each roller and rotates in a cycle. As the seed cotton is continuously fed in, the rocker arm 144 is hinged to the baling chamber 12, and the rocker arm cylinder 143 detects the pressure and extends, driving the rocker arm 144 to rotate counterclockwise, continuously forming larger cotton bales.

[0047] Furthermore, the film feeding device 13 is located behind the packaging chamber 12. After packaging is completed, the operator controls the film feeding device 13 to wrap the cotton bales.

[0048] Furthermore, the cotton support frame 11 is installed at the rear of the baling chamber 12. The two fulcrums of the cotton support frame 11 are respectively rotatably mounted on the chassis 5 and the telescopic hydraulic cylinder 10 rotatably mounted on the chassis 5. The opening and closing of the cotton support frame 11 is controlled by controlling the extension and retraction of the telescopic hydraulic cylinder 10. After the seed cotton is baled and covered, the cotton support frame 11 opens and transports the baled cotton bales to the designated location.

[0049] Furthermore, the automatic cotton picking, cleaning, and baling integrated machine has a matching hydraulic system, such as... Figure 7As shown, and automatically controlled by the control system, it can realize the automated operation of cotton picking, cleaning, and baling. The specific hydraulic system is described below:

[0050] The cotton harvesting head pump is a unidirectional variable displacement pump, which can adjust the displacement according to system needs. The high-pressure oil flowing out of the pump is divided into two parts: one part drives the cotton harvesting head motor to rotate on a fixed shaft, thus ensuring the normal operation of the cotton harvesting head 1; the other part drives the extension and retraction of the cotton harvesting head lifting cylinder through a seat valve, a check valve, and a flow divider / combiner valve, thereby adjusting the height of the cotton harvesting head 1 above the ground to ensure that the height is appropriate for cotton harvesting. The pump is equipped with a make-up pump, and the oil flowing out of the make-up pump is combined with the oil flowing out of the pump after passing through a filter, a pressure regulating valve, and a check valve to ensure that the flow rate meets the normal operating requirements of the system. An overflow valve is also provided to protect the system pressure.

[0051] The baling pump is a unidirectional variable displacement pump, which can adjust the displacement according to system needs. The high-pressure oil flowing out of the baling pump is divided into two parts: one part goes to the baling motors of the first and second drive rollers, thereby driving the first drive roller 141 and the second drive roller 145 to rotate on their fixed axes, ensuring that the baling strip 142 can circulate and roll; the other part of the oil drives the synchronous extension and retraction of the two rocker arm lifting cylinders through the throttle valve, reversing valve and seat valve, so that the rocker arm 144 can gradually rise as the seed cotton is continuously fed in, eventually forming cotton bales of a certain size and density. When the cotton bales are formed, the rocker arm 144 can descend to the initial position to prepare for the next baling. The baling pump is equipped with a baling pump replenishment pump. The oil flowing out of the baling pump replenishment pump is filtered, pressure regulating valve and check valve and merged with the oil flowing out of the baling pump to ensure that the flow rate meets the normal operation requirements of the system. At the same time, an overflow valve is set to protect the system pressure.

[0052] The pressure-compensated variable pump can adjust the displacement according to system needs and ensure stable pressure during operation. The oil flowing from the pressure-compensated variable pump is divided into five parts: the first part of the oil passes through the electromagnetic proportional flow control valve to the cotton discharge roller motor, thereby driving the cotton discharge roller 15 to rotate on a fixed shaft; the second part of the oil passes through the electromagnetic proportional flow control valve to the opening roller motor, thereby driving the opening roller 6 to rotate on a fixed shaft; the third part of the oil passes through the electromagnetic proportional flow control valve to the cotton conveying belt assembly motor, thereby driving the cotton conveying belt assembly 8 to rotate normally; the fourth part of the oil passes through the seat valve, check valve, and reversing valve to the cotton support frame telescopic cylinder, thereby driving the opening and retraction of the cotton support frame 11, so that the finished cotton bales can be placed on the cotton support frame 11 and transported to the designated location for unloading; the fifth part of the oil passes through the throttle valve, reversing valve, and hydraulic control check valve to the film feeding device cylinder, thereby driving the lifting and lowering of the film feeding device 13, so that it can wrap the formed cotton bales, and then discharge them out of the machine.

[0053] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are 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.
