Description

Technical Field

[0001] This utility model relates to the field of cotton harvester accessories, and in particular to a cotton harvester film feeding device and a cotton harvester. Background Technology

[0002] With the continuous development of agricultural machinery, cotton harvesters are gradually replacing manual cotton harvesting. A cotton harvester includes a harvesting module, a cotton finishing module, and a baling module. The harvesting module collects cotton, which is then sent to the finishing module for shaping, and finally to the baling module where it is bundled with baling film. When the baling module conveys the baling film, a film-supporting device is needed to support and guide the film to cover the cotton bales. However, existing film-supporting devices consist of two plastic plates and guide steel bars. The two plastic plates are arranged vertically, with the lower plate having a bend that supports the upper plate and creates a slope. The upper plate guides the baling film to contact the guide steel bars, and the baling film changes direction under the guidance of the guide steel bars to cover the cotton bales. However, this device has a complex structure and poor guidance, causing the baling film to shift and twist during transport, affecting the baling efficiency. Utility Model Content

[0003] To address the technical problems of complex structure and low cotton baling efficiency of the aforementioned devices, this utility model provides a cotton harvester film feeding device and a cotton harvester, which has a simple structure, can effectively control the conveying path of the baling film, has a good guiding effect, and improves the cotton baling efficiency.

[0004] The specific technical solution of this utility model is as follows:

[0005] A cotton harvester film feeding device includes a film feeding platform and several guide rollers. Several film feeding reinforcing bars are horizontally spaced on the top surface of the film feeding platform. The guide rollers are located above the film feeding reinforcing bars and a conveyor belt is connected to the guide rollers. Packing film is sandwiched between the film feeding reinforcing bars and the conveyor belt. A fixed plate is provided at the film outlet end of the film feeding platform. The fixed plate is connected to the film feeding reinforcing bars. Several horizontally arranged film feeding fingers are provided above the fixed plate. The film feeding fingers partially overlap with the film feeding reinforcing bars in the film feeding direction. The film feeding fingers have an arc-shaped guiding surface facing the guide rollers. The arc-shaped guiding surface matches the circumferential surface of the guide rollers at the film outlet end.

[0006] The aforementioned film feeding device guides the packing film through the coordinated action of the film feeding fingers and the film feeding reinforcing bars. The film feeding fingers and the film feeding reinforcing bars partially overlap in the film feeding direction, meaning there is a spatial or positional intersection between them in the film feeding direction. This allows the film material to be guided by both the film feeding fingers and the film feeding reinforcing bars simultaneously when passing through this area. The film feeding fingers and the film feeding reinforcing bars form a continuous film feeding path. At the same time, the arc-shaped guiding surface of the film feeding fingers matches the circumferential surface of the guide roller at the film exit end. That is, the arc-shaped guiding surface of the film feeding fingers and the arc curvature of the circumferential surface of the guide roller at the film exit end are consistent or coordinated, and they can work together to guide the packing film to the surface of the cotton bale. This prevents the packing film from shifting or twisting during the transportation process, increases the accuracy of guidance, and enables the packing film to accurately wrap the cotton bale, thereby improving the packing efficiency of cotton. The film feeding direction is considered longitudinal, and the direction perpendicular to the film feeding plane is considered transverse. The film feeding steel bars are installed transversely at intervals, which not only ensures that the packaging film can be stably transported along the film feeding direction, but also forms a plane on the film feeding platform to provide support for the packaging film; several film feeding fingers are arranged transversely to form a guide channel and improve the stability of film feeding.

[0007] Preferably, the film feeding finger is arc-shaped, and in the packaging state, the film feeding finger and the guide roller are concentric.

[0008] In the above technical solution, the film feeding finger and the guide roller are concentric, and the gap between them is uniform, which avoids the packing film from shifting due to uneven gaps during the transportation process, and further improves the guiding accuracy and efficiency.

[0009] Preferably, the side of the film-feeding steel bar near the film-exit end is provided with a steel bar clamping part, and the fixing plate is provided with steel bar through holes of the same number as the steel bar clamping parts, and the steel bar clamping parts are clamped with the corresponding steel bar through holes.

[0010] In the above technical solution, the fixing plate and the film-feeding steel bar are snapped together, which is convenient for loading and unloading. The fixing plate and the film-feeding steel bar have multiple connection points in the horizontal direction, which improves the connection strength and enhances the stability of the device. At the same time, the multi-point connection method makes the fixing plate evenly stressed, preventing deformation caused by excessive local stress on the fixing plate, which would affect the guiding effect of the film-feeding finger.

[0011] Preferably, the side of the film-feeding steel bar near the film-exit end is bent downward to form a bent portion, which is the steel bar clamping portion. The bent portion is opened on the side away from the film-feeding finger, and the end of the bent portion passes through the steel bar through hole and is located below the fixing plate.

[0012] In the above technical solution, the bending part has a simple structure and is easy to process. The film feeding steel bar is connected to the fixing plate through the bending part, which is convenient for loading and unloading. The bending part passes through the steel bar through hole from top to bottom and the end is located below the fixing plate to avoid obstruction of the packaging film and scratching of the packaging film.

[0013] Preferably, the film feeding platform is provided with swing drive components on both sides in the longitudinal direction, and the fixed plate is provided with fixers at both ends in the longitudinal direction, and the fixers are connected to the output end of the swing drive components.

[0014] In the above technical solution, the film-feeding reinforcing bar is engaged with the reinforcing bar through hole of the fixing plate through the bent part. The fixing plate has a movable space in the vertical direction. The swing drive causes the fixing plate to swing up and down, and the film-feeding finger and the film-feeding reinforcing bar are relatively displaced. The swing drive brings the film-feeding finger to the film-feeding position and forms a stable film-feeding path with the film-feeding reinforcing bar, guiding the delivery of the packaging film. This structure increases the flexibility of the device. By controlling the swing drive, the film-feeding finger can be quickly positioned and adjusted, thereby adapting to packaging films of different sizes. In the non-packaging state, the film-feeding finger does not come into contact with the packaging film, reducing wear on the film-feeding finger and extending its service life.

[0015] Preferably, the end of the membrane-feeding steel bar near the bend is provided with a recess.

[0016] In the above technical solution, the recessed part serves as a positioning mark to align the positions of each membrane-feeding steel bar when it is installed on the membrane-feeding platform, facilitating connection with the fixing plate.

[0017] Preferably, the film feeding finger is connected to the fixing plate by a countersunk bolt.

[0018] In the above technical solution, the bolts on the film feeding fingers are completely sunk into the film feeding fingers, and no protrusion is formed on the side of the film feeding fingers away from the fixed plate, so as to avoid obstruction of the packaging film and scratching of the packaging film.

[0019] Preferably, the film feeding finger has a positioning part on the side near the fixing plate, the positioning part and the bolt connection point are in a separate position, and the fixing plate has a groove corresponding to the positioning part.

[0020] In the above technical solution, there is no overlap or intersection between the positioning part and the bolt connection point. The film feeding finger is firmly fixed to the fixed plate through the two points of the positioning part and the bolt connection point, and its position will not shift.

[0021] Preferably, the material of the film feeding finger is aluminum alloy.

[0022] In the above technical solution, the film feeding fingers are made of aluminum alloy. Currently, film support components are often made of plastic. Plastic is easily affected by the environment and has poor mechanical properties, making it prone to breakage during the packaging process. Aluminum alloy, on the other hand, can improve the rigidity and wear resistance of the film feeding fingers, preventing deformation or breakage and thus avoiding film feeding failures.

[0023] Another specific technical solution of this utility model is: a cotton harvester, including a frame, a harvesting head, a cotton collection bin and a packing bin, and also including the above-mentioned film feeding device.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] (1) Simple structure, smooth film feeding, and good guiding effect: The film is guided by the synergistic action of the film feeding fingers and the film feeding steel bars. The film feeding fingers and the film feeding steel bars partially overlap in the film feeding direction to form a continuous film feeding path. The film feeding path has no protrusions, and the film feeding is smooth and stable. The arc-shaped guiding surface of the film feeding fingers matches the circumferential surface of the guide roller at the film outlet end, resulting in a good guiding effect.

[0026] (2) The device has high reliability and good stability: the side of the film feeding steel bar near the film outlet is bent downward to form a bending part. It is connected to the fixed plate through the bending part and has multiple connection points, resulting in high connection strength and high device stability. The film feeding fingers are made of aluminum alloy, which has high reliability. The film feeding fingers are arranged horizontally and connected to the fixed plate through countersunk bolts. Damaged film feeding fingers can be replaced individually, improving the reliability of the device. Attached Figure Description

[0036] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.

[0037] Example 1

[0038] Reference Figures 1 to 8 As shown, this utility model provides a cotton harvester film feeding device, including a feeding mechanism 1, several guide rollers 2 and a conveyor belt 3. The guide rollers 2 are located above the feeding mechanism 1, and the conveyor belt 3 is connected to the guide rollers 2. The feeding mechanism 1 includes a film feeding platform 11, several film feeding reinforcing bars 14, and a fixing plate 16. The film feeding reinforcing bars 14 are horizontally spaced on the top of the film feeding platform 11 and are fixed to the film feeding platform 11 by welding. The film feeding reinforcing bars 14 and the guide roller 2 are staggered on the horizontal plane. A packing film 4 is sandwiched between the film feeding reinforcing bars 14 and the conveyor belt 3. The fixing plate 16 is located at the film outlet end of the film feeding platform 11 and is detachably connected to the film feeding reinforcing bars 14. Above the fixing plate 16 are 36 horizontally arranged film feeding fingers 15, which are detachably connected to the fixing plate 16. The 36 film feeding fingers 15 are on the same horizontal plane and point in the film outlet direction. The film feeding fingers 15 have an arc-shaped guiding surface facing the guide roller 2. The arc-shaped guiding surface matches the circumferential surface of the guide roller 2 at the film outlet end and can cooperate to guide the packing film 4 to the surface of the cotton bundle 5. The film feeding fingers 15 and the film feeding reinforcing bars 14 overlap in the film feeding direction to form a continuous film feeding path. The end of the film-feeding reinforcing bar 14 furthest from the film exit end extends out of the film-feeding platform 11 and bends downward. The film-feeding reinforcing bar 14 forms a plane on the film-feeding platform 11, providing support for the packaging film 4. The length of this plane in the transverse direction is less than the length of the fixing plate 16 in that direction. In the packaging state, the conveyor belt 3 is always higher than the film-feeding reinforcing bar 14. In the figure, the X direction is the film-feeding direction, i.e., longitudinal, the Y direction is transverse, and the Z direction is the packaging direction of the cotton bale 5.

[0039] This device guides the packing film 4 through the synergistic action of the film feeding fingers 15 and the film feeding reinforcing bars 14. The film feeding reinforcing bars 14 guide the packing film 4 forward, while the film feeding fingers 15 guide the packing film 4 upward. The film feeding fingers 15 and the film feeding reinforcing bars 14 partially overlap in the film feeding direction, forming a continuous film feeding path. This ensures that the packing film 4 can be smoothly and stably conveyed along the film feeding direction. The arc-shaped guiding surface of the film feeding fingers 15 matches the circumferential surface of the guide roller 2 at the film exit end, and they can work together to guide the packing film 4 to the surface of the cotton bale 5. This prevents the packing film 4 from shifting or twisting during the conveying process, increases the accuracy of guidance, and enables the packing film 4 to accurately wrap the cotton bale 5, improving the cotton packing efficiency. The transverse arrangement of several film feeding reinforcing bars 14 and film feeding fingers 15 forms a guiding channel, improving the stability of film feeding.

[0040] Reference Figure 5 As shown, the implementation of this device is as follows: the feeding mechanism 1 moves forward to the guide position, the packaging film 4 enters from the film feeding platform 11 at the film inlet end, the guide roller 2 rotates, driving the conveyor belt 3 to move, the packaging film 4 is sandwiched between the conveyor belt 3 and the film feeding steel bar 14, driven by the conveyor belt 3, and stably conveyed to the film feeding finger 15 along the film feeding direction guided by the film feeding steel bar 14. The packaging film 4 is sandwiched between the film feeding finger 15 and the conveyor belt 3, the arc-shaped guide surface of the film feeding finger 15 matches the circumferential surface of the guide roller 2 connected to the conveyor belt 3 at that point, and the gap is small, guiding the packaging film 4 to move upward and making the packaging film 4 fit with the conveyor belt 3. Under the guidance of the conveyor belt 3, it contacts the cotton bundle 5, and along the packaging path formed by the packaging belt, it wraps the cotton bundle 5 in the Z direction. After packaging is completed, the feeding mechanism 1 returns to its original position.

[0041] Example 2

[0042] Based on Example 1, such as Figures 1 to 8 As shown, this utility model provides a film feeding device for a cotton harvester. A film feeding platform 11 has swing drive components 18 on both sides along its longitudinal direction, and a fixing plate 16 has fixing devices 17 at both ends along its longitudinal direction. The fixing devices 17 are connected to the output ends of the swing drive components 18 by screws. A film feeding finger 15 is connected to the fixing plate 16 by countersunk bolts. The film feeding finger 15 has a flared bolt through hole 151, and the fixing plate 16 has a corresponding bolt connection port. The sum of the length of the bolt through hole 151 and the length of the bolt connection port is greater than the bolt length, allowing the bolt to be completely recessed into the film feeding finger 15. The film feeding finger 15 is made of aluminum alloy with a smooth, burr-free surface. A protruding positioning part 152 is provided on the side near the fixing plate 16. The positioning part 152 is cylindrical and is separated from the bolt connection point, with no overlap or intersection between them. The fixing plate 16 has a groove corresponding to the positioning part 152. The film feeding finger 15 is arc-shaped, and in the packaging state, the film feeding finger 15 and its corresponding guide roller 2 are concentric.

[0043] In this embodiment, the fixing plate 16 is an integral structure. The fixing plate 16 has a steel bar through hole 161 corresponding to the film feeding steel bar 14. The steel bar through hole 161 is a waist-shaped groove. The side of the film feeding steel bar 14 near the film outlet end is bent downward to form a bent part 141. In this embodiment, the bent part 141 is the steel bar clamping part. The bend angle of the bent part 141 is an acute angle. The bent part 141 is inserted into the steel bar through hole 161, and the fixing plate 16 can move relative to the bent part 141. The bent part 141 is opened on the side away from the film feeding finger 15. The end of the film feeding steel bar 14 near the bent part 141 is provided with a recessed part 142. The fixing plate 16 is a single welded component, which simplifies assembly and increases structural stability. Each film-feeding rebar 14 participates in the connection with the fixing plate 16, resulting in high connection strength. The bending portion 141 has a simple structure and is easy to process. The film-feeding rebar 14 is snapped into the fixing plate 16 through the bending portion 141, making loading and unloading convenient. Furthermore, the highest point of the bending portion 141 is lower than the highest point of the film-feeding finger 15, and the highest point of the bending portion 141 does not contact the packing film 4, making film feeding smoother and preventing scratches on the packing film 4. Understandably, in another embodiment, the fixing plate 16 has an opening facing the film-feeding rebar 14 on the lower side near the film-feeding finger 15. The bending portion 141 passes through the rebar through hole 161 from top to bottom and its end is snapped into the lower opening of the fixing plate 16 to achieve snap-fit. The recessed portion 142 serves as a positioning mark, facilitating the alignment of the positions of each film-feeding rebar 14 during installation and improving the connection efficiency with the fixing plate 16.

[0044] In this embodiment, the film-feeding reinforcing bar 14 is engaged with the reinforcing bar through hole 161 of the fixing plate 16 through the bending part 141. The fixing plate 16 has a movable space in the vertical direction. The swing drive 18 drives the fixing plate 16 to swing upward, causing relative displacement between the film-feeding finger 15 and the film-feeding reinforcing bar 14. The swing drive 18 brings the film-feeding finger 15 to the film-feeding position and forms a stable film-feeding path with the film-feeding reinforcing bar 14, guiding the conveying of the packaging film 4. This structure increases the flexibility of the device. By controlling the swing drive 18, the film-feeding finger 15 can be quickly positioned and adjusted, thereby adapting to packaging films 4 of different sizes. In the non-packaging state, the film-feeding finger 15 does not contact the packaging film 4, reducing wear on the film-feeding finger 15 and extending its service life. The film-feeding finger 15 and the guide roller 2 are concentric, and the gap between them is uniform, avoiding the packaging film 4 from shifting due to uneven gaps during conveying, further improving guiding accuracy and efficiency. The bolts on the film feeding finger 15 are fully recessed into the film feeding finger 15, without forming a protrusion on the side of the film feeding finger 15 away from the fixing plate 16, to avoid obstructing the feeding of the packaging film 4 and scratching the packaging film 4. There is no overlap or intersection between the positioning part 152 and the bolt connection point. Through these two points, the film feeding finger 15 is firmly fixed to the fixing plate 16 and its position will not shift. The film feeding finger 15 is made of aluminum alloy. Currently, film support components are often made of plastic. Plastic is easily affected by the environment and has poor mechanical properties, making it prone to breakage during the packaging process. Aluminum alloy improves the rigidity and wear resistance of the film feeding finger 15, preventing deformation or breakage and thus avoiding film feeding failures.

[0045] The implementation of this device is as follows: In the packaging state, the feeding mechanism 1 moves forward to the guide position, and the swing drive 18 drives the fixed plate 16 to swing upward, fixing the film feeding finger 15 at the film feeding position and forming a stable film feeding path with the film feeding steel bar 14. The packaging film 4 enters from the film feeding platform 11 at the film inlet end. The guide roller 2 rotates, driving the conveyor belt 3 to move. The packaging film 4 is sandwiched between the conveyor belt 3 and the film feeding steel bar 14. Driven by the conveyor belt 3, it is stably conveyed to the film feeding finger 15 along the film feeding direction guided by the film feeding steel bar 14. The packaging film 4 is sandwiched between the film feeding finger 15 and the conveyor belt 3. The arc of the guide roller 2 connected to the conveyor belt 3 at this position matches the film feeding finger 15, and the gap is small, guiding the packaging film 4 to move upward and making the packaging film 4 fit with the conveyor belt 3. Under the guidance of the conveyor belt 3, it contacts the cotton bundle 5 and wraps the cotton bundle 5 along the Z direction along the packaging path formed by the packaging belt. After packaging is completed, the swing drive 18 drives the fixed plate 16 back to the original position, and the feeding mechanism 1 returns to the original position.

[0046] Example 3

[0047] Based on Example 1, such as Figures 1 to 8As shown, this utility model provides a cotton harvester film feeding device. The fixing plate 16 is spliced ​​from several connecting plates. The fixing plate 16 has a steel bar through hole 161 corresponding to the film feeding steel bar 14. The film feeding steel bar 14 has a steel bar clamping part on the side near the film outlet end. In this embodiment, the steel bar clamping part is designed as a fork-shaped opening. The steel bar clamping part is inserted into the steel bar through hole 161, and the fork-shaped opening is engaged with the side wall of the steel bar through hole 161. The end of the film feeding steel bar 14 near the steel bar clamping part is provided with a recess 142.

[0048] In this embodiment, the fixing plate 16 is assembled from multiple connecting plates, offering high flexibility. The number of film-feeding fingers 15 can be adjusted according to the size of the cotton bundle 5, and maintenance is convenient and cost-effective. The recessed portion 142 serves as a positioning mark, facilitating the alignment of the film-feeding reinforcing bars 14 during installation and improving the connection efficiency with the fixing plate 16. The fixing plate 16 and the film-feeding reinforcing bars 14 are interlocked, making installation and removal convenient. The fixing plate 16 and the film-feeding reinforcing bars 14 have multiple connection points in the lateral direction, improving the connection strength and enhancing the stability of the device. At the same time, the multi-point connection method ensures that the fixing plate 16 is subjected to uniform force, preventing deformation or decomposition of the fixing plate 16 due to excessive local force, which could affect the guiding effect of the film-feeding fingers 15. The highest point of the reinforcing bar interlocking portion is lower than the highest point of the film-feeding fingers 15, and the highest point of the reinforcing bar interlocking portion does not contact the packing film 4 to avoid obstructing the transport of the packing film 4 and scratching the packing film 4.
