Description

Technical Field

[0001] The invention relates to the field of agricultural machinery and equipment, in particular to a through-type automatically tensioned cotton film feeding synchronous conveying belt for a cotton picker. Background Art

[0002] The speed and quality of cotton film delivery, a crucial component in baling operations, are directly related to the quality of bale formation and the overall performance of the cotton picker. The film delivery mechanism consists of a film delivery roller and a film delivery belt that together hold the film and deliver it to the baling bin.

[0003] The utility model patent with application number 202222672845.8 provides an active cotton picker baling film conveying device, including a film feeding device, the film feeding device is connected to the bottom of the rear warehouse, and the film feeding device is connected to the rear warehouse through a rotating arm plate and a film feeding device oil cylinder. The film feeding device 3, the transmission shaft 2, the universal coupling, the transmission shaft 1, the gear set, the main transmission shaft and the power input are respectively provided with a transmission shaft structure. The power input structure inputs power from the baling roller to the main transmission shaft, and the main transmission shaft is directly connected to the passive wheel. The main transmission shaft then drives the transmission shaft 1 to rotate through the gear set. The transmission shaft 1 is connected to the transmission shaft 2 through the universal coupling. The transmission shaft 2 is then connected to the transmission shaft 3 through the universal coupling, thereby driving the synchronous rotation of the six belt groups. The utility model adds an active film feeding mechanism, thereby greatly improving the success rate of film feeding and improving the quality of cotton bales.

[0004] While the aforementioned technology can actively feed film, the traditional film feeding mechanism utilizes a multi-segmented, separate belt coupled with a film roller. This drawback is that the asynchronous linear speeds of the front and rear sections of the film feed belt can lead to film wrinkling, damage, and blockage, impacting both film feeding and baling quality. The improved film feed belt is a single, unsegmented, continuous belt, driven by a single power shaft. This ensures that each belt maintains a consistent linear speed, preventing film wrinkling and significantly improving film feeding quality. Furthermore, due to the long-term, continuous operation of a taut film feed belt, it can easily loosen, reducing the pulley wrap angle and causing slippage. Therefore, a tensioning device is required near the driven pulley of each film feed belt to maintain the pulley wrap angle and prevent film wrinkling and damage caused by slippage. The complex functions of cotton pickers result in complex operating conditions for the film feed belt, placing high demands on the conveyor belt structure. Therefore, an improved design for a through-the-belt conveyor belt with a built-in tensioning device is particularly important. However, traditional conveyor belt structures struggle to prevent film blockage and damage during film feeding. Summary of the Invention

[0025] As attached Figure 3 As shown, the driven pulley 42, the second tensioning wheel bracket 44, and the second tensioning wheel spring 45 are all fixed to the driven wheel fixing frame 41 by bolts; the second tensioning wheel 43 is fixed to the second tensioning wheel bracket 44 by bolts; one end of the second tensioning wheel spring 45 is fixed to the driven wheel fixing frame 41 by bolts, and the other end is fixed to the hole of the second tensioning wheel bracket 44 by a hook structure at the tail of the spring.

[0026] As attached Figure 4 As shown, the film feeding guide rail 10 is laterally provided with three concave structures, and the film feeding guide rail limit plate 23 is laterally provided with several openings with the same width as the diameter of the film feeding guide rail 10; the transverse concave structure of the film feeding guide rail 10 passes through the film feeding guide rail limit plate 23 and is fixed by the film feeding guide rail limit rod 24; the film feeding guide rail limit plate 23 is fixed to the film feeding guide rail support frame 21 by bolt connection; the left end of the film feeding guide rail 10 is provided with a downward bending structure 22 with a bending radius of 10 to 15 cm to prevent the cotton film from being scratched and damaged during transportation; the right end of the film feeding guide rail 10 is provided with an upward protruding structure 25 with a bending radius of 3 to 8 cm, which is lifted upward when the cotton film is fed into the packaging bin to prevent the cotton film from being blocked; the film feeding belt assembly 3 is provided with four groups in total, which are arranged laterally, and the vertical height of the film feeding belt 9 of each group is consistent; the transverse guide rail support frame 8 has a mounting hole at the front and rear, which can be installed on the cotton picker frame through other components.

[0027] Example 2

[0028] The difference between Example 2 and Example 1 is that an airbag and a cable are provided on the side of the first tensioning spring near the film feed guide support frame 21. The cable wraps around the airbag and then connects to the first tensioning spring near the tensioning pulley support 38. When the airbag is inflated, the airbag expands, and the cable pulls the first tensioning spring a distance, causing it to compress, thereby causing the film feed belt 9 to be loose. It should be noted that in this state, the film feed belt 9 can still rotate and complete the film feeding operation. The airbag is provided with an air inlet and an air outlet. The air inlet is connected to a pump. When the synchronous power transmission shaft 1 is just started, the pump is turned on to inflate the airbag. After the airbag is filled with gas, the pump is stopped. This puts the film feed belt 9 in a loose state. When the synchronous power transmission shaft 1 has a constant speed or the startup time reaches a certain value (for example, 5 seconds), the air release valve provided on the air outlet is opened, slowly deflated, and the first tensioning spring slowly resets until the film feed belt 9 is tightened. In this solution, the synchronous power transmission shaft 1 drives several groups of film feeding belts 9 to move together. However, the synchronous power transmission shaft 1 is too long, and torque may vary between the side of the motor and the side away from the motor. The amplitude and vibration of the far end may be greater than that of the near end. When the motor is just started, the speed changes greatly, which will amplify this disadvantage. If all the driven film feeding belts 9 are in a tight state at this time, the superimposed vibration of the synchronous power transmission shaft 1 may superimpose the vibration on the film feeding belt 9 during rotation, causing damage to the film feeding belt 9. The airbag in this solution is a protective measure. Before each start, the airbag is inflated to loosen the belt, which will not affect the film feeding. At this time, it also provides more deformation margin to cope with the deformation caused by vibration. When the airbag is deflated, it is slow and gradual, that is, the film feeding belt 9 will not be suddenly tightened during operation. The normal use of the film feeding belt 9 is guaranteed.
