Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and more specifically, relates to a double-outlet bale pressing and cutting device for a square baler. Background Technology

[0002] Baling technology plays a crucial role in the mechanized production of forage. Square balers have a high market share in the overall baler market, thus playing a key role in the mechanized forage production process. A square baler is a type of forage machinery mainly used to compress loose forage into rectangular bales, facilitating transportation and storage, and promoting the recycling and reuse of straw such as rice, corn, and forage stalks.

[0003] Currently, the cross-sectional dimensions of square balers used for forage harvesting in China are mainly fixed large cross-sections of approximately 1200×870mm and fixed small cross-sections of approximately 440×350mm. This results in significant variations in the weight of the harvested bales, and the lack of diversity in cross-sectional specifications makes it difficult for single machines to meet market and user demands due to regional differences in bale size and weight requirements. Therefore, the prevalence of uniform cross-sectional dimensions and the extreme polarization in volume and weight of harvested bales are significant factors hindering the development of square balers. Summary of the Invention

[0004] This invention provides a double-outlet bale pressing and cutting device for a square bale machine. Without changing the size and specifications of the pressing cavity, the square bale is divided into two. The bale-cutting mechanism is conveniently installed on the square bale machine, improving the applicability of the device.

[0005] To achieve the above objectives, the present invention proposes a double-outlet bale pressing and cutting device for a square baler, wherein the double-outlet bale pressing and cutting device is disposed between the feeding device and the baling device of the square baler, and includes:

[0006] A frame, wherein a bundling chamber is provided inside the frame, and rails are provided on both sides of the frame of the bundling chamber;

[0007] The baling mechanism includes a baling piston disposed in the baling cavity and a crank-connecting rod structure connected to the front end of the baling piston. The crank-connecting rod structure is connected to the output shaft for transmission. Rollers are provided on both sides of the baling piston. The rollers are connected to the track. The output shaft drives the baling piston to reciprocate along the track.

[0008] The sub-packaging mechanism includes a piston-driven vertical blade, a stationary vertical blade, and a vertical blade slide rail. The piston-driven vertical blade is connected to the rear end of the compression piston and is vertically positioned in the middle of the compression piston. The stationary vertical blade is vertically positioned at the rear end of the compression chamber and corresponds to the position of the piston-driven vertical blade. The stationary vertical blade is connected to the frame via a stationary blade seat plate. The vertical blade slide rail is positioned between the piston-driven vertical blade and the stationary vertical blade. The vertical blade slide rail is connected to the top of the compression chamber via a vertical blade slide rail seat. The upper side of the piston-driven vertical blade fits against the side of the vertical blade slide rail, thereby restricting the movement trajectory of the piston-driven vertical blade. The compression piston drives the piston-driven vertical blade to reciprocate along the vertical blade slide rail, creating a shearing effect with the stationary vertical blade.

[0009] Preferably, it further includes a bundling plate, which is vertically disposed on the rear side of the vertical blade and connected to the vertical blade base plate.

[0010] Preferably, the crank-connecting rod structure includes a left crank-connecting rod structure and a right crank-connecting rod structure symmetrically arranged at the front end of the compression piston, and the left crank-connecting rod structure and the right crank-connecting rod structure are respectively connected to the output shaft for transmission.

[0011] Preferably, the top of the bundling cavity is provided with an upper cover plate, the bottom plate of the bundling mechanism is connected to the rear end of the upper cover plate, and the vertical knife slide seat includes a first vertical knife slide seat and a second vertical knife slide seat. The first vertical knife slide seat is connected to the upper surface of the upper cover plate, and the vertical knife slide is connected to the lower surface of the upper cover plate through the first vertical knife slide seat.

[0012] The second vertical knife slide seat is connected to the upper surface of the base plate of the bundling mechanism. The second vertical knife slide seat includes a vertical knife slide adjustment plate, and the lateral position of the vertical knife slide is adjusted by the second vertical knife slide seat.

[0013] Preferably, the upper and lower parts of the vertical blade holder plate are vertically connected to the frame at the rear end of the compression chamber via the upper vertical blade holder plate and the lower vertical blade holder plate, respectively.

[0014] Preferably, the vertical cutter base plate is provided with adjusting pads between the lower vertical cutter base plate and the upper vertical cutter base plate to adjust the lateral position of the vertical cutter.

[0015] Preferably, the rear end of the compression piston is provided with a piston vertical blade holder, and the piston vertical blade is bolted to the piston vertical blade holder.

[0016] Preferably, an adjusting pad is provided between the inner side of the piston vertical blade and the piston vertical blade holder to adjust the lateral position of the piston vertical blade.

[0017] Preferably, the rear end of the compression piston is provided with a horizontal moving blade, and the frame is provided with a horizontal fixed blade. The horizontal moving blade and the horizontal fixed blade are positioned correspondingly. The compression piston reciprocates, driving the horizontal moving blade and the horizontal fixed blade to form a shearing effect.

[0018] Preferably, the rollers include upper rollers and lower rollers disposed on both sides of the clamping piston, and the track includes upper track and lower track disposed on both sides of the clamping cavity, wherein the upper rollers and the lower rollers are respectively connected to the upper track and the lower track; the upper track is provided with side rollers on its side, and the side rollers are installed on the upper part of the clamping piston.

[0019] The beneficial effects provided by this invention are as follows: When the dimensions of the bundling cavity remain unchanged, the square bundling machine equipped with this double-outlet bundling and cutting device can produce square bundles of different sizes by assembling or disassembling the piston-driven vertical blade and the vertical blade. The vertical blade and the vertical blade of the bundling mechanism divide the square bundle into two, and the resulting two bundles are less likely to stick together under the action of the bundling plate. When the piston-driven vertical blade and the vertical blade move relative to each other, they form an angle, dispersing the force during the bundling process and reducing instantaneous load. The vertical blade slide rail restricts the movement position of the piston-driven vertical blade during movement, preventing collision between the piston-driven vertical blade and the vertical blade, thus improving the safety of the device. The vertical blade and the piston-driven vertical blade are fixed by bolts, improving the maintainability and replaceability of the blades. Adjustment pads are provided in the vertical blade seat plate and the piston-driven vertical blade seat, improving the applicability of the device.

[0036] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1-12 As shown, an embodiment of the present invention provides a double-outlet bale pressing and cutting device for a square baler. This double-outlet bale pressing and cutting device is disposed between the feeding device and the baling device of the square baler, and includes:

[0038] The machine includes a frame 1, a binding chamber 4, and rails 18 on both sides of the binding chamber 4; a binding mechanism, comprising a binding piston 11 disposed within the binding chamber 4 and a crank-connecting rod structure 9 connected to the front end of the binding piston 11, the crank-connecting rod structure 9 being driven by an output shaft; rollers 17 on both sides of the binding piston 11, the rollers 17 being connected to the rails 18; and a packaging mechanism, comprising a piston-moving knife 7, a stationary knife 13, and a moving knife slide 16, the piston-moving knife 7 being connected to the rear end of the binding piston 11. The vertical blade 13 is vertically positioned in the middle of the compression piston 11 and is vertically positioned at the rear end of the compression chamber 4, corresponding to the position of the piston moving blade 7. The vertical blade 13 is connected to the frame 1 through the vertical blade seat plate 12. The moving blade slide 16 is positioned between the piston moving blade 7 and the vertical blade 13. The moving blade slide 16 is connected to the top of the compression chamber 4 through the moving blade slide seat. The upper side of the piston moving blade 7 fits against the side of the moving blade slide 16, thereby restricting the movement trajectory of the piston moving blade 7. The compression piston 11 drives the piston moving blade 7 to reciprocate along the moving blade slide 16, forming a shearing effect with the vertical blade 13.

[0039] Specifically, the baling piston 11 reciprocates within the baling chamber 4, and the piston-driven vertical blade 7 slides along the vertical blade slide rail 16, forming a shearing motion with the stationary blade 13, cutting a single straw sheet 20 into two straw sheets. Under the reciprocating action of the baling piston 11, the two straw sheets of pasture or crop straw are baled into two bales 21. This double-outlet baling and cutting device for square balers is flexible to disassemble. Without changing the dimensions of the baling chamber 4, different bale sizes can be produced by assembling or disassembling the piston-driven vertical blade 7 and the stationary blade 13.

[0040] In this embodiment, as Figure 11 As shown, the double-outlet bale pressing and cutting device for the square baler also includes a baling plate 2, which is vertically positioned behind the vertical blade 13 and connected to the vertical blade base plate 12. During the material baling process, the baling plate 2 blocks between the two bales to prevent them from sticking together.

[0041] In this embodiment, as Figure 2As shown, the crank-connecting rod structure 9 includes a left crank-connecting rod structure and a right crank-connecting rod structure symmetrically arranged at the front end of the compression piston. The left and right crank-connecting rod structures are respectively connected to the output shaft for transmission. Specifically, the left and right crank-connecting rod structures are symmetrically arranged and connected to the same drive shaft, so that the left and right crank-connecting rod structures together drive the compression piston 11 to move, ensuring the uniformity of the compressed bales.

[0042] In this embodiment, as Figure 3 , Figure 6 , Figure 9 , Figure 10 and Figure 11 As shown, the top of the bundling cavity 4 is provided with an upper cover plate 10. The bottom plate 8 of the bundling mechanism is connected to the rear end of the upper cover plate 10. The vertical knife slide seat includes a first vertical knife slide seat 14 and a second vertical knife slide seat 15. The first vertical knife slide seat 14 is connected to the upper surface of the upper cover plate 10, and the vertical knife slide 16 is connected to the lower surface of the upper cover plate 10 through the first vertical knife slide seat 14. The second vertical knife slide seat 15 is connected to the upper surface of the bottom plate 8 of the bundling mechanism. The second vertical knife slide seat 15 includes a vertical knife slide adjustment plate 6, and the lateral position of the vertical knife slide 16 is adjusted through the second vertical knife slide seat 15.

[0043] Specifically, such as Figure 9 As shown, the first vertical moving cutter slide seat 14 includes a pair of horizontally arranged mounting brackets 25 and a first strip plate 26 disposed between the pair of mounting brackets 25. The pair of mounting brackets 25 are bolted to the upper surface of the upper cover plate 10, and one end of the vertical moving cutter slide 16 is bolted to the lower surface of the upper cover plate 10 with the first strip plate 26. Figure 11 As shown, the second vertical moving knife slide seat 15 includes a horizontally arranged vertical moving knife slide adjustment plate 6 and a vertically arranged second strip plate. The bottom of the vertical moving knife slide adjustment plate 6 is provided with a groove that cooperates with the second strip plate. The other end of the vertical moving knife slide 16 is bolted to the lower surface of the bundling mechanism base plate 8. The horizontal position of the vertical moving knife slide 16 is adjusted by the vertical moving knife slide adjustment plate 6, and the vertical moving knife slide 16 is fixedly installed on the lower surface of the upper cover plate 10 and the bundling mechanism base plate 8 by the first vertical moving knife slide seat 14. By adjusting the position of the vertical moving knife slide 16, the shearing angle between the piston vertical moving knife 7 and the vertical stationary knife 13 can be adjusted.

[0044] In this embodiment, as Figure 11 As shown, the upper and lower parts of the vertical blade holder plate 12 are vertically connected to the frame at the rear end of the binding chamber 4 via the upper vertical blade holder plate 5 and the lower vertical blade holder plate 3, respectively. Figure 7As shown, the stationary tool holder plate 12 and the stationary tool 13 are connected by bolts. In this embodiment, the stationary tool holder plate 12 is provided with adjusting shims between the lower stationary tool holder plate 3 and the upper stationary tool holder plate 5, respectively, for adjusting the lateral position of the stationary tool 13.

[0045] In this embodiment, as Figure 1 , Figure 3 and Figure 8 As shown, the rear end of the compression piston 11 is provided with a piston vertical blade holder 22. The piston vertical blade 7 is installed on the piston vertical blade holder 22 by bolts. An adjusting pad is provided between the piston vertical blade 7 and the inner side of the piston vertical blade holder 22 to adjust the lateral position of the piston vertical blade 7 and to adjust the shearing angle with the stationary blade 13.

[0046] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, a horizontal moving blade 19 is provided at the bottom rear end of the clamping piston 11, and a horizontal fixed blade 23 is provided on the frame. The positions of the horizontal moving blade 19 and the horizontal fixed blade 23 correspond to each other. The clamping piston 11 reciprocates horizontally, driving the horizontal moving blade 19 and the horizontal fixed blade 23 to form a shearing effect. The horizontal moving blade 19 and the horizontal fixed blade 23 are each composed of multiple blades. The horizontal moving blade 19 is arranged horizontally along the bottom rear end of the clamping piston 11, and the horizontal fixed blade 23 is arranged horizontally on the frame corresponding to the position of the horizontal moving blade. Both the horizontal moving blade 19 and the horizontal fixed blade 23 are installed by bolts for easy replacement after wear. In this embodiment, as... Figure 1 As shown, the rear end of the horizontal fixed blade 23 is provided with a grass-blocking plate 24. The grass-blocking plate 24 has a wave-tooth structure. After the baling piston 11 reciprocates to compress the material into grass sheets, the grass-blocking plate 24 can prevent the baling piston 11 from sticking to the grass sheets and moving in the opposite direction, ensuring that the internal structure of the compressed grass square is compact and uniform.

[0047] In this embodiment, as Figure 1 As shown, roller 17 includes an upper roller and a lower roller disposed on both sides of the clamping piston 11, and track 18 includes an upper track and a lower track disposed on both sides of the clamping cavity 4. The upper roller and the lower roller are respectively connected to the upper track and the lower track. Side rollers are provided on the side of the upper track and are disposed on the upper part of the clamping piston 11. The clamping piston 11 moves along the upper track and the lower track through the upper roller and the lower roller, which can precisely control the reciprocating motion trajectory of the clamping piston 11. The side rollers on the side of the upper track can limit the left and right movement position of the clamping piston 11, further limiting the movement trajectory of the piston vertical blade 7, and ensuring the cutting position with the vertical blade 13.

[0048] The working principle of this embodiment is as follows: Figure 2 and Figure 12As shown, in this embodiment, when the double-outlet bale pressing and cutting device for the square baler is working, the piston-driven vertical blade 7 reciprocates with the piston 11, creating a shearing effect with the stationary blade 13. During one reciprocating motion, as the material is fed up, the piston-driven vertical blade 7 pushes the material forward with the piston. The piston-driven vertical blade slide 16 restricts the movement trajectory of the piston-driven vertical blade 7, preventing it from colliding with the stationary blade 13. When the piston-driven vertical blade 7 pushes the material forward and interacts with the stationary blade 13, the material is split in two. Simultaneously, the piston-driven vertical blade 7 and the stationary blade... During operation, the piston-driven vertical blade 7 and the stationary blade 13 have a certain angle, which can reduce the load. The material is continuously fed up and is divided into two by the shearing effect of the piston-driven vertical blade 7 and the stationary blade 13, thus completing the packaging function. The bundling plate 2 blocks the separated materials, making it difficult for the materials to stick together. At the same time, the connection between the piston-driven vertical blade 7 and the stationary blade 13 is equipped with adjusting shims, which can adjust the gap between them. The method of adjusting the gap with adjusting shims can reduce the manufacturing precision of the device and improve the economy and applicability of the device.

[0049] Without changing the dimensions of the bundling chamber, a square bundling machine equipped with this double-outlet bundling and cutting device can divide a square bundle into two by assembling the piston-driven vertical blade 7 and the stationary blade 13. The resulting two square bundles are less likely to stick together under the action of the bundling plate 2. When the piston-driven vertical blade 7 and the stationary blade 13 move relative to each other, they form an angle, dispersing the force during the double-bundle formation process and reducing instantaneous load. The vertical blade slide 16 restricts the movement position of the piston-driven vertical blade 7 during its movement, preventing collisions between the piston-driven vertical blade 7 and the stationary blade 13, thus improving the safety of the device. The stationary blade 13 and the piston-driven vertical blade 7 are fixed with bolts, improving the maintainability and replaceability of the blades. Adjustment pads are provided for both the stationary blade 13 and the piston-driven vertical blade 7, enhancing the applicability of the device.

[0050] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
