Description

Technical Field

[0001] The utility model relates to a cotton straw harvesting and baling machine, belonging to the technical field of agricultural machinery. Background Art

[0002] Cotton is an important cash crop. As a by-product of cotton production, cotton straw has a huge annual output. Cotton straw has different uses in aspects such as soil improvement, livestock feed, cultivation substrate, and additive materials. The existing treatment method of cotton straw is that first, a forage harvester cuts the cotton straw and transports it to a following vehicle, and then the cotton straw is transported to a baling site for baling or transported to a power plant as fuel, or directly burned. However, during the process of harvesting cotton straw, first, the following vehicle needs to transport the cotton straw back and forth for baling work, which reduces the harvesting efficiency of cotton straw. Currently, there is no device that can directly compact and bale cotton straw during the harvesting process. Second, most of the cutters of forage harvesters are driven by a complex sprocket and chain drive structure. This drive structure of the cutter has a large power output, a complex structure, and is easy to damage. Third, the cutter and the drum of the cutter rotate at the same speed, which results in an unsatisfactory harvesting effect of cotton straw. It cannot completely transport the cotton straw to the following vehicle. When the speed is relatively fast, not all cotton straw will enter the conveying device. In addition, since the forage harvester rolls the plastic film and the cotton straw together during cutting, the plastic film is mixed into the cotton straw, so that the cotton straw cannot be used as feed and loses its use as feed.

[0039] The cutter transmission case 10 includes a gearbox I 24, a gearbox II 25, and a right-angle box 26. The right-angle box 26 is located on top of the gearbox II 25, and the gearbox I 24 is located on one side of the gearbox II 25 and the right-angle box 26. At the upper end inside the gearbox I 24, a driving input shaft 27 serving as the main driving shaft is installed. A cylindrical gear a 28 is installed on the driving input shaft 27. At the lower end inside the gearbox I 24, a cylindrical gear b 29 is installed. An intermediate gear I 41 is meshed and connected between the cylindrical gear b 29 and the cylindrical gear a 28. One end of the driving input shaft 27 is exposed outside the gearbox I 24 and is connected to the protruding shaft at the front end of the corresponding cutter drive box b 9. At the other end of the driving input shaft 27, a driving input bevel gear 30 is installed. The driving input bevel gear 30 is located in the right-angle box 26. At the connection between the right-angle box 26 and the gearbox II 25, a bearing seat 31 is installed. A vertically oriented connecting sleeve shaft 32 is installed in the bearing seat 31. At the top of the connecting sleeve shaft 32, a cutter head transmission bevel gear 33 is installed. The cutter head transmission bevel gear 33 is located in the right-angle box 26 and is meshed and connected to the driving input bevel gear 30.

[0040] One end of the axle of the cylindrical gear b 29 is installed with a driven output bevel gear 34. The driven output bevel gear 34 is located in the gearbox II 25. Below the gearbox II 25, a collecting roller shaft tube 14 provided in the disk cutter 13 is fitted and connected to the shaft body of the connecting sleeve shaft 32. At the top of the collecting roller shaft tube 14, a roller transmission bevel gear 35 is installed. The roller transmission bevel gear 35 is located in the gearbox II 25 and is meshed and connected to the driven output bevel gear 34. The roller transmission bevel gear 35 is supported by the bottom of the gearbox II 25. At the bottom end of the connecting sleeve shaft 32, a spherical plain bearing with a flanged round housing 39 is installed. The spherical plain bearing with a flanged round housing 39 is installed on the bottom plate of the lower mounting frame 1 of the disk cutter. The blade 1302 of the disk cutter 13 is fixedly connected to the lower end of the connecting sleeve shaft 32 through a blade mounting disc.

[0041] On the inner sides of both side wall plates 205 of the bale pressing chamber in the roller packing power box 2, an inner nylon plate 40 is fixedly connected. At both ends of the auger 18, stirring blades 1801 are provided. The middle position of the auger 18 is the shaft body, and the stirring blades 1801 at both ends are symmetrically arranged. At the bottom of the lower mounting frame 1 of the disk cutter, a number of low rollers 48 in the same axial direction are installed. On the gearbox mounting plate 11, two cross-symmetric oil cylinders 47 are installed.

[0042] During operation, the cotton straw harvester and baler is connected to the tractor through the lower suspension device on the front bogie 3. The drive device on the tractor is connected to the input shaft 43 on the front bogie 3. The input shaft 43 in the front bogie 3 drives the input shaft 43 in the rear bogie 4 to rotate. Then, the input shaft 43 in the rear bogie 4 drives the upper and lower spline shafts 44 in the first gearbox 7 to rotate. The upper spline shaft 44 drives the main sprocket 204 to rotate through the wide-angle cross spline coupling, which drives the extending shafts on both sides of the main input box 203 of the roller baling power box 2. One of the main sprockets 204 drives the drive sprocket b23 on the transmission box 12 through the transmission chain. At the same time, it also drives all the rollers 201 to rotate through the sprocket and chain structure on the inner and outer sides of the side wall plates 205 of the baling chamber of the roller baling power box 2. The drive sprocket b23 drives the coaxial crushing drive sprocket 21 to rotate. The crushing drive sprocket 21 then drives the drive sprocket a22 mounted on the crushing cutter shaft 19 through the transmission chain. This drive sprocket a22 drives another drive sprocket a22 mounted on the auger 18 through the transmission chain. In this way, the crushing drive sprocket 21 drives the crushing cutter shaft 19 and the auger 18 to rotate under the support of the bearings. Then, the gear B37 on the crushing cutter shaft 19 drives the gear A36 on the small cutter roller shaft 16 to rotate through the intermediate gear II 38. The gear A36 can drive the small cutter roller shaft 16 to rotate under the support of the bearings.

[0043] The lower spline shaft 44 in the first gearbox 7 drives the extending shafts on both sides of the cutter drive box a8 to rotate under the support of the bearings. The extending shafts on both sides of the cutter drive box a drive the extending shafts on both sides of the adjacent cutter drive box b9 to rotate under the support of the bearings and are transmitted step by step between two adjacent cutter drive boxes b9. At the same time, the extending shafts at the front ends of the cutter drive boxes b9 start to drive the driving input shaft 27 of the cutter transmission box 10 to rotate under the action of bevel gear transmission, and the cutter transmission box 10 starts to work.

[0044] The driving input shaft 27 drives the cylindrical gear a28 and the driving input bevel gear 30 to rotate. The driving input bevel gear 30 directly drives the cutter head transmission bevel gear 33 to drive the connecting sleeve shaft 32 to rotate under the support of the spherical outer surface ball bearing 39 of the circular seat with a boss and the bearing seat 31. The connecting sleeve shaft 32 directly drives the blade 1302 of the disc cutter 13 to quickly cut the exposed bottom end of the cotton straw. The blade 1302 is 100 mm above the ground, and the rotation speed of the blade 1302 can reach 1000 - 1200 revolutions per minute. At the same time, the cylindrical gear a28 drives the cylindrical gear b29 to rotate through the intermediate gear I41. The cylindrical gear b29 drives the coaxial driven output bevel gear 34 to rotate. The driven output bevel gear 34 drives the drum transmission bevel gear 35 to drive the aggregate drum shaft tube 1301 to rotate. The aggregate drum shaft tube 1301 drives the aggregate drum 1306 of the disc cutter 13 and the small grain separating teeth, aggregate teeth, and grain guiding and conveying teeth on the aggregate drum 1306 to rotate through the fixed aggregate drum web plates 1303, transverse support frames 1304, and inclined support tubes 1305 on itself. After the cotton straw is cut by the blade 1302, the cotton straw is guided by the guide tube 46 under the bottom plate of the lower mounting frame 1 of the disc cutter, and the small grain separating teeth, aggregate teeth, and grain guiding and conveying teeth convey the cut cotton straw. In this way, through the mutual transmission between the gears, the purpose of reducing the speed of the aggregate drum 1306 is achieved. The rotation speed of the aggregate drum 1306 is relatively slow, with a speed of 500 - 600 revolutions per minute. In this way, the blade 1302 of the disc cutter 13 and the aggregate drum 1306 work separately, and both rotate independently.

[0045] Then the disc cutter 13 transfers the cut cotton straw to the transmission box 12. After the cotton straw enters the transmission box 12, first, the small knife roller shaft 16 and the front knife roller blade 17 in the transmission box 12 push and transfer the cut cotton straw to the crushing knife shaft 19. Then, the crushing knife shaft 19 drives the crushing cutter 20 to push and transfer the cotton straw towards the direction of the auger 18, and the symmetrically arranged stirring blades 1801 at both ends of the auger 18 gather the cotton straw towards the middle position. Through step-by-step transfer, finally, the feeding mechanism 206 in the roller packing power box 2 conveys the cotton straw into the roller packing power box 2. Then, the rotating roller 201 in the roller packing power box 2 compresses the gradually gathered cotton straw into bundles, and then the packing device 45 at the top of the roller packing power box 2 directly packs and discharges the cotton straw in bundles.

[0046] The inner nylon plates 40 fixed on the inner side of the wall panels 205 on both sides of the baling chamber in the roller baling power box 2 can prevent the temperature in the baling chamber from being too high and causing friction fire; the baler is tilted downward by 9.8 degrees when working, so that the low roller 48 will always be in contact with the ground film on the ground. Through the friction force of contact with the ground, the low roller 48 can press the ground film on the ground to prevent the ground film from being rolled into the cotton straw; two cross-symmetrical oil cylinders 47 are installed on the gearbox mounting plate 11, which can lift the two ends of the disc cutter lower mounting frame 1 and the disc cutter 13 and the cutter transmission box 10 contained therein and place them at 90 degrees, which is convenient for loading and transportation.
