Description

Pull-type intelligent cotton press

Technical Field

The invention relates to the field of cotton bundling and harvesting machinery, in particular to a traction type intelligent cotton baler for bundling and enveloping picked cotton by a picking machine in a picking process.

Background

Cotton pickers can be classified into pneumatic type cotton pickers, comb type cotton pickers, spindle type cotton pickers, vibration type cotton pickers, roller type cotton pickers, and the like. The horizontal spindle type cotton picker in spindle type is the most widely used type at home and abroad, the horizontal spindle type cotton picker is mostly self-propelled, and the representative type is the American John Diel 7760 type. The cotton picker with the horizontal spindle picking mechanism is a cotton picker with various cotton pickers, and the impurity content of the cotton pickers is the lowest, but is close to about 10%. The cotton picking is mainly carried out by a combined machine, cotton picking and cotton packing are carried out simultaneously, and the cotton is wrapped after the cotton picking is finished, so that the impurity rate of the wrapped cotton is kept at about 10 percent. The cotton picker includes a horizontal spindle type cotton picker such as a box type cotton picker like john dill 7760, usa. When the horizontal spindle type cotton picker collects the fully stored cotton boxes, the work can be continued by pouring the cotton boxes (mainly pouring the cotton boxes to the ground for boxing and transportation). The trash content of the cotton can be increased in the process of pouring the cotton box, and can be increased to about 15% -30%. The higher impurity content leads to the increase of the cotton cleaning process in the later processing of cotton and the increase of the production cost.

As shown in fig. 8, the box 101 is divided into two boxes (a front box on the left side and a rear box on the right side in fig. 8). The set of bale rollers 2023 has a plurality of rollers disposed in the bale case 101 as shown. The bundling rocker arm 2021 has a curvature, one end of which is hinged to the front wall of the front box of the cotton box 101, and the other end of which is also provided with four rollers. A baling belt 2022 is connected to the rollers on the baling roller set 2023 and the baling swing arm 2021 in the manner shown in fig. 8. The baling cylinder may apply pressure to the baling arm 2021, causing the baling arm 2021 to rotate about the hinge point to tension the baling belt 2022, thereby applying pressure to the cotton bale being formed.

As can be seen from fig. 8, the film feeding mechanism 203 includes a cotton film storage supporting portion 2031, a cotton film conveying portion 2032, and a film feeding portion 2033.

The third and fourth bars in the four-bar linkage 2034b, which are hinged as described above, also have two free ends that are connected to the ends of two support rollers 2031a, respectively. So that when the moving end of the film changing cylinder 2034a is contracted, the two support rollers 2031a are separated from each other, and the standby packaging film roll F supported thereon falls; and when the moving end of the cylinder is extended, the two supporting rollers 2031a are brought close to each other to a distance smaller than the diameter of the standby packaging film roll F, so that the remaining standby packaging film roll F does not fall. And the guide groove functions to ensure that the hinge point of the first and second levers in the four-link mechanism 2034b can maintain a linear motion without a left-right shift.

The cotton film feeding section 2032 includes two support rollers 2032a, a film sheet feeding roller 2032b, a film feeding conveyor 2032c, and a film transfer plate 2032 d. The two support rollers 2032a are fixedly arranged for supporting the standby packaging film roll F falling from above and the film roll can rotate on the rollers. The film input roller 2032b is located right below the two rubber rollers, and the cotton film is wound out from the cotton film roll by rotation. The film-following plate 2032d is disposed obliquely to the front side (i.e., the left side in fig. 8) of the film feeding roller 2032b, and has the same inclination as that of the lower right belt 2022 in fig. 8. The film feeding belt 2032c is located entirely below the film sheet feeding roller 2032b, and has the same inclination as the film backing plate 2032 d. The film feeding conveyor 2032c is composed of a belt and two rubber rollers located at both ends of the belt, and the rubber roller located at the right end in fig. 8 is a film winding transmission rubber roller 2032c 1.

The film feeding portion 2033 includes a film feeding conveyor 2033a, a film feeding table 2033b, a first swing arm 2033c, a second swing arm 2033d, a third swing arm 2033e, and a film feeding cylinder 2033 f. The first swing arm 2033c is hinged at one end to the bottom of the cotton box 101 near the feeding port and at the other end to the film feeding table 2033 b. One end of the second swing arm 2033d is also hinged to the film feeding table 2033b, and the hinge point is the same as the first swing arm 2033 c; and the other end of the second swing arm 2033d is hinged to the rear box of the cotton box 101. One end of the third swing arm 2033e is hinged to the film feeding platform 2033b, and the other end is hinged to the rear box body of the cotton forming box 101, and is always parallel to the second swing arm 2033 d. The fixed end of the film feeding cylinder 2033f is hinged to the bottom of the rear box body of the cotton box 101, while the moving end is hinged to the hinged point of the first swing arm 2033c and the film feeding platform 2033 b. Thus, the operation of the film feeding cylinder 2033f can drive the three swing arms to drive the film feeding platform 2033b to move away from or close to the cotton forming box 101. The film feeding conveyor 2033a is mounted on the top of the film feeding table 2033b, and when the film feeding table 2033b is lifted close to the cotton box 101, the height of the film feeding conveyor 2033a can make the cotton film contact the bale 2022.

The housing of the film feeding mechanism 203 includes an upper cover 2034, a back plate 2035, a right side plate 2036, a left side plate 2037, and a connecting frame 2038 at the front end.

The power input mechanism 3 shown in fig. 2 and 3 is applied only to the first embodiment of the traction-type intelligent cotton baler shown in fig. 11. As in the embodiment of fig. 11, the operation of the packing mechanism 202 is controlled primarily by mechanical power. In fig. 11, thick solid lines indicate the power transmission route in the intelligent traction-type cotton baler according to the present invention, thin solid lines indicate the hydraulic medium flow route in the hydraulic system, broken lines indicate the electrical connection relationship, and dotted lines indicate the transportation route of the cotton being processed. The power receiving mechanism 301 receives power transmitted from the tractor through the input shaft 307 and the first transmission shaft 308 and then distributes the power to the transmission mechanism 302 and the electro-hydraulic grouping device 309, respectively. The electro-hydraulic grouping device 309 then redistributes power, one of the paths being to deliver power to the power supply module 502 through the motor drive 310; the second of the distribution paths transmits power to the hydraulic pump 401. The motor 5021 in the power supply module 502 receives mechanical power and then operates to generate electricity, and charges the lithium battery 5022, and then the lithium battery 5022 provides electric power to the main controller 501. The setting of lithium cell 5022 not only can carry out steady voltage and steady flow to the electric power that motor 5021 produced, can also store the electric energy to still can supply power to main control unit 501 when emergency scram appears in the tractor, realize the effect of protection main control unit 501 and rather than the display 12 who is connected. In addition, the emergency stop condition of the tractor can be conveniently and timely processed by an operator in an emergency. After the electric hydraulic grouping device 309 distributes power to the hydraulic pump 401, the hydraulic pump 401 is driven to operate, and then the hydraulic pump 401 supplies pressure medium to hydraulic actuators in the traction type intelligent cotton baler. The hydraulic pump 401 supplies pressure medium to a hydraulic control valve group 403, the hydraulic control valve group 403 distributes the pressure medium to the cotton collecting tank 101 and the cotton forming tank 201, and the distributed pressure medium controls the operation of each hydraulic motor and the hydraulic oil cylinder. Because the baling press is in the course of the work, hydraulic medium can be compressed to hydraulic control valves 403 repeatedly and is distributed to in each hydraulic motor and hydraulic cylinder repeatedly by hydraulic control valves 403, can improve hydraulic medium's temperature to increase the risk that the system leaked. The detection unit of the present invention therefore further comprises a temperature sensor 605, the temperature sensor 605 collecting the temperature of the hydraulic medium in the hydraulic oil tank 402 and feeding back to the main controller 501. In addition, the present invention further provides a cooling device 404 to cool the return oil, in this embodiment, the cooling device 404 is an air cooling fan. After receiving the temperature information fed back by the temperature sensor 605, the main controller 501 compares the temperature information with a preset standard temperature, if the temperature reaches or exceeds a preset value, the main controller 501 controls the cooling device 404 to be started, the return oil is cooled, and if the temperature returns to below the preset value, the cooling device 404 is closed.

The cotton picker picks cotton and pours the cotton into a cotton collecting box 101 in the cotton collecting mechanism 1, and a shaping mechanism 102, a conveying mechanism 103, an extruding mechanism 104 and a feeding mechanism 105 are arranged in the cotton collecting box 101. The grooming mechanism 102 breaks up the just-entered cotton and transports it towards the bottom of the hopper 101. The reforming mechanism 102 includes an agitation structure 1021 and an agitation hydraulic motor 1022 that drives the agitation structure 1021. The agitation structure 1021 is driven to rotate by an agitation hydraulic motor 1022, thereby dispersing the cotton fluffing. The reshaped cotton is transported toward the bottom of the hopper 101. The conveying mechanism 103, the extruding mechanism 104 and the feeding mechanism 105 are sequentially arranged at the bottom of the cotton collecting box 101 from left to right. The transport mechanism 103 transports the cotton towards the feed inlet. The conveying mechanism 103 includes a squeegee belt 1031 and a squeegee hydraulic motor 1032. The squeegee belt 1031 is driven to operate by a squeegee hydraulic motor 1032 to convey cotton. The cotton is further extruded into cotton pieces by an extrusion mechanism 104 before passing through the feed opening for subsequent baling and wrapping processes. The pressing mechanism 104 is composed of a feed roller group 1041 and a feed roller hydraulic motor 1042 driving the feed roller group 1041, thereby pressing cotton into sheets. Finally, the cotton sheet is transferred from the feeding mechanism 105 to the forming mechanism 2. The feeding mechanism 105 is actually a conveyor belt mechanism, and is composed of a belt 1053, a conveying roller 1051, and a plurality of support rollers 1054. The conveying roller 1051 is positioned at the rightmost end and is driven by a feeding motor 1052 to rotate, and a belt 1053 is driven to run to realize the feeding of cotton sheets. All the mechanisms are hydraulic motors, pressure medium is distributed by the hydraulic control valve group 403 in the hydraulic control device 4, and the rotating speed is monitored by the rotating speed sensor 603. When cotton is jammed at the feeding port of the cotton collecting box 101, the rotation speed of the feeding motor 1052 is reduced, and the rotation speed sensor 603 feeds back to the main controller 501 in the main control device 5. After receiving the feedback of the rotation speed, the main controller 501 compares the rotation speed with a standard preset rotation speed, and controls the hydraulic control valve group 403 to change the position when the rotation speed is lower than the preset value, so as to reduce or stop the rotation speed of the driving scraper hydraulic motor 1032 and the feeding roller hydraulic motor 1042. At the same time, the main controller 501 sends a control command to the hydraulic control valve group 403 to reverse the feeding motor 1052, and controls the hydraulic control valve group 403 to shift the position, so as to drive the feeding motor 1052 to reverse, and the cotton blocked at the feeding port returns to the cotton collecting box 101 again. After a period of time (about 1s to 2s), the system automatically determines that the blockage is eliminated, the main controller 501 sends a control command to the hydraulic control valve group 403, the process is repeated, and the cotton is output again.

The cotton forming box 201 in the forming mechanism 2 receives the cotton sheets from the cotton collecting box 101. A baling mechanism 202 in a bale case 201 then bales the cotton pieces into bales. In the present embodiment (i.e., the first embodiment shown in fig. 11), the packing mechanism 202 is driven by the chain transmission mechanism 303. As can be seen from fig. 2, 3 and 11, the input end of the chain transmission 303 is connected to the mechanical clutch 304 via the output transmission shaft 318 so as to receive the power transmitted by the speed change mechanism 302, while in the present embodiment, the rotation speed sensor 603 also monitors the rotation speed of the transmission chain in the chain transmission 303. And the mechanical clutch 304 may be disengaged and engaged under the control of the clutch cylinder 305. The operation of the cotton collecting box 101 and the cotton forming box 201 is relatively independent, and an operator can independently control the operation or stop of the packing mechanism 202 in the cotton forming box 201 when the cotton quantity is insufficient and can not meet the packing requirement or the feeding port is blocked. The baling cylinder applies pressure to the cotton bale being formed by the baling arm 2021 during baling so that the baling arm 2021 rotates to tension the baling belt 2022 to compact the cotton bale, whereby measuring the pressure of the baling cylinder reflects the tightness of the cotton bale. As can be seen in fig. 8, the rocker 202 abuts against the tangent of the cylindrical bale and as the bale grows, the rocker 2021 is lifted upwards, so that it has a rotation angle relative to its hinge point, which is measured in response to the bale size. During the baling process, the angle sensor 602 in the detection unit detects the angle of rotation of the baling arm 2021, and the pressure sensor 601 detects the hydraulic pressure of the baling cylinder (i.e., detects the pressure applied to the cotton bale). The information collected by the two sensors is fed back to the main controller 501, and is displayed in the display 12 through the main controller 501. In the invention, the conversion relation exists between the rotating angle of the bundling rocker arm 2021 and the size of the cotton bundle, and the main controller 501 can calculate the size of the cotton bundle according to the angle collected by the angle sensor 602. Meanwhile, the main controller 501 can obtain the compactness of the cotton bale according to the pressure applied to the cotton bale by the bale forming oil cylinder and calculate the weight of the cotton bale according to the size and the compactness of the cotton bale. The main controller 501 can send an adjusting instruction to the hydraulic control valve set 403, so as to adjust the compression degree of the cotton bale in real time, and make the cotton bale compactness relatively consistent. When the size of the cotton bale and the pressure of the oil cylinder reach preset values, the bundling work is automatically finished, and then the film coating work is carried out. Therefore, the cotton bale is continuously adjusted in the forming process, and finally the formed cotton bale with consistent size and weight is obtained. And the main controller 501 collects the size of the cotton bale during molding and the final bale weight through satellite positioning feedback, and can know the acquisition condition through remote control and remotely lock the traction type intelligent cotton baler.

At the end of bundling, the main controller 501 controls the electromagnetic clutch 204 to close, and the power of the cotton forming box 201 is transmitted to the electromagnetic clutch 204 through a chain transmission (only the film wrapping clutch transmission sprocket 204a is shown in fig. 9) and is transmitted to the film input roller 2032b in the film feeding mechanism 203. A clutch tension sprocket 204b is also arranged on the output side of the electromagnetic clutch 204. The film sheet feeding roller 2032b receives power to wind the cotton film from the cotton film roll, and the forward direction of the cotton film sheet is held by the forward film plate 2032 d. The film sheets are then conveyed forward by the film conveying belt 2032c to the film feeding portion 2033. The rotation speed sensor 603 detects the rotation speed of the strapping belt 2022, the main controller 501 receives the rotation speed information and compares the rotation speed information with a preset value, and when the rotation speed information reaches the preset value, a control instruction is sent to the hydraulic control valve group 403. The hydraulic control valve group 403 shifts to distribute hydraulic medium to the film feeding cylinder 2033f, so that the moving end of the film feeding cylinder 2033f extends out to drive the three swing arms to move, thereby driving the film feeding table 2033b to move close to the bundling belt 2022, and enabling the cotton film on the film feeding conveyor belt 2033e to contact the bundling belt 2022. Under the action of friction, the cotton film sheet enters the cotton forming box 101 along with the bundling belt 2022. After the cotton film enters the cotton forming box 101, the main controller 501 sends a control instruction to the hydraulic control valve group 403, the hydraulic control valve group 403 shifts, the film feeding cylinder 2033f reversely acts to drive the three swing arms to rotate, and the film feeding table 2033b returns to the initial position. The invention also arranges a light emitter and a light receiver on two sides of the cotton diaphragm to sense the feeding condition of the cotton diaphragm. The main body of the cotton film is transparent, but the connection part of the cotton film and the other cotton film is provided with an opaque separation label. When the cotton film is conveyed, light emitted by the light emitter penetrates through the transparent main part of the cotton film to be received by the light receiver. When the opaque separating label blocks the light beam of the light emitter, the light receiver feeds back to the main controller 501, and the main controller 501 controls the electromagnetic clutch 204 to separate (i.e. reverse attraction). The film feed roller 2032b stops rotating, but the bale belt 2022 does not stop rotating and pulls the cotton film into the cotton forming box 101. Due to the pulling action, the bond between the currently coated piece of cotton sheeting and the next piece of cotton sheeting breaks and its tail with the adhesive sticks to the bale. When two cotton sheets are separated, the film feed counter sensor 604 counts one. Meanwhile, the display 12 shows that the number of the cotton films is one less. While the next cotton film piece is positioned on the film feeding station 2033b in preparation for the next film wrapping. The main controller 501 sends a control command to the hydraulic control valve set 403, the hydraulic control valve set 403 shifts, pressure medium is distributed to the clutch cylinder 305, the clutch cylinder 305 is driven to control the mechanical clutch 304 to be disengaged, the chain transmission mechanism 303 stops rotating, and the rotation speed sensor 603 feeds back the control command to the main controller 501. And then the main controller 501 sends a control command to the hydraulic control valve group 403, the hydraulic control valve group 403 is switched, and pressure media are distributed to the bin opening oil cylinders in the bin opening mechanism 205. The bin opening oil cylinder drives the bin gate of the cotton bin 201 to open to unload the cotton bale onto the cotton unloader 1101, and then the hydraulic control valve group 403 is switched to close the bin gate of the cotton bin 201.

Cotton unloader 1101 is attached to frame 9. And the cotton discharging cylinder 1102 is controlled by pressure medium distributed by the hydraulic control valve group 403 and is used for driving the cotton discharging device 1101 to discharge cotton bales. The present invention also provides a light sensor 1103 for detecting the presence of a bale on the doffer 1101. The light sensor 1103 is responsible for collecting light information on the cotton discharging device 1101, when a cotton bale is on the cotton discharging device 1101, the light sensor 1103 obtains a signal to feed back to the main controller 501, the main controller 501 sends a control instruction to the hydraulic control valve group 403, the hydraulic control valve group 403 is switched, and pressure media are distributed to the cotton discharging cylinder 1102, so that the cotton discharging device 1101 discharges cotton to the cotton bale, and the cotton bale is discharged to the ground without being damaged.

When the intelligent traction cotton baler is pulled by a tractor to walk, the intelligent traction cotton baler needs to perform actions such as braking, steering indication, controlling tires in the walking mechanism 10 to steer and the like according to conditions. Therefore, in the embodiment shown in fig. 4, a walking brake device 39 is also included. The walking brake device 39 is controlled by the hydraulic control valve group 403 to act, so that the tires in the walking mechanism 10 are real under the action of hydraulic pressure, and the hydraulic control valve group 13 is controlled to change the position, so as to control the steering of the packer. The operator can control the steering lamp of the synchronous tractor of the traction type intelligent cotton baler through the steering electric control device,

fig. 12 shows a second embodiment of a mobile cotton processing apparatus according to the present invention. In fig. 12, thick solid lines indicate the power transmission route in the intelligent traction cotton baler according to the invention, thin solid lines indicate the hydraulic medium flow route in the hydraulic system, broken lines indicate the electrical connection relationship, and dotted lines indicate the transport route of the cotton being processed. In the present embodiment, only different from the driving manner of the baling mechanism 202 in the cotton box 201 in the embodiment shown in fig. 11, one baling drive hydraulic motor 306 is provided downstream of the hydraulic control valve group 403 for providing the driving force to the baling mechanism 202 in the present embodiment. The speed sensor 603 monitors the speed of the pack drive hydraulic motor 306 and feeds back to the main controller 501. Otherwise, the embodiment shown in fig. 12 is the same as that of fig. 11. When the traction type intelligent cotton press according to the two embodiments of the present invention starts to work, a certain amount of cotton is already stored in the cotton collecting box 101, the driving chain mechanism 303 or the press driving hydraulic motor 306 rotates, and the speed is measured by the rotation speed sensor 603 and fed back to the main controller 501. The main controller 501 compares the rotation speed with a preset value, and if the rotation speed reaches the preset value, a control instruction is sent to the hydraulic control valve group 403, the hydraulic valve group 403 shifts, a pressure medium is distributed to the feeding motor 1052, and the rotation of the feeding motor 1052 is enabled to be carried out while the rotation speed is measured by the rotation speed sensor 603. When the feeding motor 1052 reaches the set rotating speed and keeps unchanged, the main controller 501 controls the hydraulic valve group 403 to switch positions, distributes pressure medium to the scraper motor and the feeding roller hydraulic motor 1042 to drive the scraper motor and the feeding roller hydraulic motor to rotate so as to feed cotton, and the two hydraulic motors are simultaneously tested by the rotating speed sensor 603.
