Description

Technical Field

[0001] This utility model relates to the field of hay bale collection machinery technology, specifically an inclined hay bale picking machine. Background Technology

[0002] With the advancement of agricultural integration, more and more agricultural operations are adopting mechanized processing methods. Mechanized hay bale picking and stacking operations involve using machinery to bale crops such as pasture and rice / wheat straw, and then having the machinery complete all processes such as picking, loading, transporting, and stacking, thereby replacing the heavy manual picking and stacking work.

[0003] However, existing bale pickers have at least the following defects and shortcomings: The picker uses chain drive to transport bales to the collection platform. During the collection of alfalfa bales and straw bales, the chain directly contacts the bales, causing grass leaves to fall off and the ropes to break apart, resulting in a high bale loss rate. Alfalfa, being a concentrated feed, has a higher protein content in its grass leaves than in its stalks, and its market value depends primarily on the amount of grass leaves in each bale. It is particularly unsuitable for straw and wheat straw mesh bag bales, as these have short fibers and low moisture content, making them difficult or even impossible for existing pickers to collect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an inclined hay bale picking machine that can not only pick up traditional hay bales (two-rope hay bales and three-rope hay bales), but also pick up net bag hay bales without damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An inclined bale picker includes a body, a spring-loaded chain assembly, an inclined chain, and a horizontal chain. The body has an inclined panel facing downwards, and the inclined chain is installed on the inclined panel. A horizontal panel is located at the top of the inclined panel, and a horizontal chain is installed on the horizontal panel. The spring-loaded chain assembly is located at the bottom of the inclined chain. Each of the spring-loaded chain assembly, the inclined chain, and the horizontal chain has a bale-carrying plate. The spring-loaded chain assembly has a spring. The spring-loaded chain assembly lifts the bale from the ground to the inclined panel, the inclined chain moves the bale up to the horizontal panel, and the horizontal chain conveys the bale to the collection platform.

[0007] Furthermore, the grass-carrying plate is an acute-angled triangular plate, and the grass-carrying plates are evenly distributed and installed on the chain to form a star-shaped rotating plate.

[0008] Furthermore, it also includes a pressure plate device, which is installed above the spring chain assembly to apply downward pressure to the bales.

[0009] Furthermore, the pressure plate device includes a pressure plate, a bracket, a rotating shaft, a limiting plate, and a tension spring; the pressure plate and the limiting plate are mounted on the rotating shaft, the rotating shaft is hinged to the bracket, one end of the tension spring is connected to the limiting plate, and the other end is connected to the bracket.

[0010] Furthermore, it also includes a guide roller, the axis of which is vertically arranged and installed on the inside of the corner between the inclined panel and the horizontal panel.

[0011] Furthermore, it also includes a torsion spring guide device, which is installed on one side of the tilt panel and the horizontal panel; the torsion spring guide device includes a torsion spring and a column, the column is vertically fixed to the machine body, and the torsion spring is installed on the column.

[0012] Furthermore, the spring-loaded chain assembly includes a support frame, a sprocket frame, a main shaft, a drive sprocket, a driving sprocket, a driven sprocket, and a chain; the support frame, sprocket frame, drive sprocket, and driving sprocket are mounted on the main shaft, the driven sprocket is mounted on the sprocket frame, the chain is mounted on the driving sprocket and the driven sprocket, the support frame is connected to the machine body, and the sprocket frame is connected to the machine body via a spring.

[0013] Furthermore, it also includes a hydraulic cylinder clamping mechanism, which includes a guide plate and a hydraulic cylinder. The guide plate is hinged to the bottom of the machine body and includes a first guide plate and a second guide plate. The first guide plate and the second guide plate are symmetrically arranged in a figure-eight shape. The hydraulic cylinder is connected to the guide plate, and the hydraulic cylinder drives the guide plate to rotate to clamp the bale.

[0014] Furthermore, it also includes a check hook and a check spring. The check hook is hinged to the guide plate, and one end of the check spring is connected to the check hook, while the other end is connected to the guide plate.

[0015] Furthermore, it also includes a chain tensioning device, which includes a tensioning bracket, a torsion spring, and a roller; one end of the tensioning bracket is hinged to the machine body, the torsion spring is installed on both sides of one end of the tensioning bracket, and the roller is hinged to the other end of the tensioning bracket; the roller contacts the chain and uses the force provided by the torsion spring to lift the chain.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] 1. This utility model comprises an inclined panel, a horizontal panel, a horizontal chain, and an assembly of an inclined chain and a spring-loaded chain. Each of the spring-loaded chain assembly, the inclined chain, and the horizontal chain is equipped with a grass-carrying plate, and the spring-loaded chain assembly is equipped with a spring. When the pickup machine, towed by a tractor, collides with a bale, the weight of the bale presses against the spring-loaded chain assembly. Under the reaction force of the spring, the spring-loaded chain assembly exerts an upward force on the bale, lifting the front end of the bale. The spring-loaded chain then carries the bale upward to the inclined panel. The inclined chain moves the bale upward along the inclined panel. When the bale reaches the top, the horizontal chain moves the bale horizontally along the horizontal panel to the collection platform. The grass-carrying plates on the chain of this utility model push the bale along the inclined and horizontal panels. The bale moves on the panels rather than on the chain, avoiding grass falling, rope cutting, and bale scattering, resulting in a low bale loss rate. This invention can not only pick up traditional straw bales (two-strand and three-strand straw bales), but also pick up straw bales in net bags without damage, truly realizing mechanical replacement of manual picking, which not only saves time and effort, but also improves the quality and efficiency of the operation.

[0018] 2. The hay bale conveyor of this utility model adopts a special star-shaped rotating plate, which will not damage the hay bale during the transmission process.

[0019] 3. This utility model is equipped with a torsion spring guide device to ensure that the bale moves along the panel. When the bale reaches the top, it is driven by the torsion spring guide device to rotate 90 degrees in the direction of travel and be horizontally transported to the platform along the direction of the connecting arm, thus transferring the bale to the platform.

[0020] 4. This utility model is equipped with a pressure plate device, which mainly serves as a limit device. When the bale of grass bounces upward under the action of the spring tooth chain, it will not detach from the inclined panel. The tension spring plays a reset role. Each time the bale of grass is lifted up by the flying bale of grass, it is subjected to the tension of the tension spring and applies downward pressure to the bale of grass in the opposite direction, ensuring that the bale of grass does not detach from the inclined panel and moves upward smoothly.

[0021] 5. The first guide plate and the second guide plate of the hydraulic cylinder clamping mechanism of this utility model are symmetrically arranged in a figure-eight shape; the guide plates play a guiding and correcting role for the bales during the picking process.

[0022] 6. The anti-reverse hook of the hydraulic cylinder clamping mechanism of this utility model can effectively prevent the bales from backing up during the picking process.

[0023] 7. This utility model is equipped with a guide roller, which can rotate in the same direction as the hay bale when it turns 90 degrees, thus playing a guiding role and reducing resistance.

[0024] 8. During the picking process, the hay bales are clamped by the hydraulic cylinder clamping mechanism, which will not damage the hay bales and can ensure that the nutrients of the hay bales and leaves will not be lost due to damage to the hay leaves during the picking process.

[0025] 9. This utility model includes a chain tensioning device for tensioning the chain. This ensures that the chain maintains appropriate tension during transmission, preventing decreased transmission efficiency and increased energy consumption due to an overly loose chain, as well as wear and damage caused by an overly tight chain. Appropriate tension ensures that the chain will not jump or slip during transmission, thereby improving transmission efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0043] like Figure 1-5As shown, an inclined bale picker includes a body 1 and a pressure plate device 2, a torsion spring guide device 3, a spring tooth chain assembly 4, a hydraulic cylinder clamping mechanism 5, an inclined chain 6, a horizontal chain 7, a guide roller 8, and a chain tensioning device 9 installed on the body.

[0044] like Figure 5 As shown, the machine body 1 includes a machine body support 11, a horizontal panel 12, an inclined panel 13, and a connecting arm 14. The machine body 1 is connected to the tractor and the collection platform via the connecting arm 14. The horizontal panel 12 is horizontally positioned, and the inclined panel 13 is inclined downwards, with its top end connected to the right end of the horizontal panel 12 and its left end connected to the connecting arm 14. The machine body support 11 is located at the bottom end of the inclined panel 13. The angle between the inclined panel 13 and the horizontal panel 12 is the tilt angle of the inclined pickup. The horizontal panel 12 has a groove in the middle, and the horizontal chain 7 is installed in the groove. The inclined panel 13 has a groove in the middle, and the inclined chain 6 is installed in the groove. The spring tooth chain assembly 4, the inclined chain 6, and the horizontal chain 7 are driven synchronously by a motor.

[0045] The guide roller 8 is vertically oriented and installed inside the corner between the horizontal panel 12 and the inclined panel 13. When the bale turns 90 degrees, the guide roller 8 can rotate in the same direction as the bale, thus providing guidance and reducing resistance.

[0046] In this embodiment, two torsion spring guide devices 3 are provided, respectively installed on the outer side of the tilt panel 13 and the outer side of the horizontal panel 12. Each torsion spring guide device 3 includes a guide torsion spring 31 and a column 32. The column 32 is vertically fixed to the body 1, and the guide torsion spring 31 is mounted on the column 32. The guide torsion spring 31 has a stop arm; the stop arm of the guide torsion spring installed on the outer side of the tilt panel 13 is parallel to the tilt panel 13, and the stop arm of the guide torsion spring installed on the outer side of the horizontal panel 12 is parallel to the horizontal panel 12.

[0047] When the bale reaches the top, it is guided by the torsion spring guide device 3 and rotated 90 degrees in the direction of travel by the horizontal chain 7, and is horizontally transported to the platform along the direction of the connecting arm, thus transferring the bale to the platform.

[0048] like Figure 6As shown, the pressure plate device 2 is installed above the spring chain assembly 4, applying downward pressure to the bales. The pressure plate device 2 includes a pressure plate 21, a bracket 22, a rotating shaft 23, a limiting plate 24, a tension spring 25, and a limiting rubber pad 26. The pressure plate 21 and the limiting plate 24 are mounted on the rotating shaft 23, with the pressure plate 21 located in the middle of the shaft 23 and the two limiting plates 24 located at both ends of the shaft 23. Both ends of the rotating shaft 23 are hinged to the bracket 22 via bearings. One end of the tension spring 25 is connected to a tension spring hook 251 on the limiting plate 24, and the other end is connected to a tension spring hook 251 on the bracket 22. The limiting rubber pad 26 is fixed to the bracket 22 and cooperates with the limiting plate 24 to provide limiting and buffering functions. The bracket 22 is connected to the machine body 1 via U-bolts, and the height of the pressure plate 21 can be adjusted by adjusting the height of the U-bolts. The tension spring 25 acts as a reset mechanism. Each time the bale is lifted by the flying bale, the tension spring 25 exerts a downward pressure on the bale in the opposite direction, ensuring that the bale does not detach from the tilt panel 13 and moves upward smoothly.

[0049] like Figure 7 , Figure 8 As shown, the spring-tooth chain 4 assembly includes a support frame 41, a sprocket frame 42, a main shaft 43, a drive sprocket 44, a driving sprocket 45, a driven sprocket 46, a chain 47, a grass-carrying plate 48, and a tension spring 25.

[0050] The support frame 41, sprocket frame 42, drive sprocket 44, and driving sprocket 45 are mounted on the main shaft 43. The drive sprocket 44 is connected to the motor via chain drive. The motor drives the drive sprocket 44 to rotate, which in turn drives the driven sprocket 46 and chain 47 to rotate. The sprocket frame 42 is provided with a tension spring hook 251. One end of the tension spring 25 is connected to the tension spring hook 251 on the sprocket frame 42, and the other end is connected to the machine body.

[0051] The hay-carrying plate 48 is a right-angled triangle with one angle of 30° and the other angle of 60°. It is connected to the chain 47 at the right angle and is set upward at the 30° angle. The hay-carrying plates 48 are evenly distributed on the chain 47 to form a star-shaped rotating plate, ensuring that the hay bales are not damaged during transmission.

[0052] The motor drives the drive sprocket 44 to rotate, which in turn drives the driven sprocket 46 and chain 47 to lift the hay bale upwards, thus lifting the hay bale from the ground to the inclined panel 13.

[0053] like Figure 1-4 As shown in Figures 9-11, the hydraulic cylinder clamping mechanism 5 includes a first guide plate 51, a second guide plate 52, a hydraulic cylinder 53, a backstop hook 54, and a backstop spring 55.

[0054] The first guide plate 51 and the second guide plate 52 are hinged to the bottom of the machine body 1. The first guide plate 51 and the second guide plate 52 are symmetrically arranged in a figure-eight shape. The oil cylinder 53 is connected to the first guide plate 51 and the second guide plate 52 through a connecting plate. The oil cylinder 53 drives the first guide plate 51 and the second guide plate 52 to rotate synchronously to clamp the bale.

[0055] The guide plate guides and corrects the hay bales during the picking process. The hydraulic clamping mechanism 5 clamps the hay bales during picking, preventing damage and ensuring that the nutrients in the hay leaves are not lost due to damage during the picking process.

[0056] The anti-reverse hook 54 is hinged to the inner sides of the first guide plate 51 and the second guide plate 52. The anti-reverse hook 54 is an acute-angled triangle, inclined in the direction of grass transport, with the arrow indicating the direction of grass transport. One end of the anti-reverse spring 55 is connected to the anti-reverse hook 54, and the other end is connected to the guide plate. The anti-reverse hook 54 can prevent the grass bale from rolling backward during the picking process. When the grass bale moves along the direction of grass transport and touches the anti-reverse hook 54, it causes the anti-reverse hook 54 to rotate, stretching the anti-reverse spring 55, causing the grass bale to leave the anti-reverse hook 54, and then return to its original position under the elastic force of the anti-reverse spring 55. If the direction of movement of the grass bale is opposite to the direction of grass transport, the anti-reverse hook 54 will stop the grass bale from moving forward, effectively preventing the grass from rolling backward.

[0057] like Figure 12 , 13 As shown, the chain tensioning device 9 includes a tensioning bracket 91, a torsion spring 92, and a roller 93. The top of the tensioning bracket 91 is hinged to the body 1. The torsion spring 92 is installed on both sides of the top of the tensioning bracket 91, and the roller 93 is hinged to the bottom of the tensioning bracket 91. The roller 93 contacts the chain 47 and uses the force provided by the torsion spring to lift the chain 47. The chain tensioning device 9 tensions the chains in the spring-tooth chain assembly 4, the angled chain 6, and the horizontal chain 7. This ensures that the chain maintains appropriate tension during transmission, avoiding a decrease in transmission efficiency and an increase in energy consumption due to excessive slack, as well as wear and damage caused by excessive tension. Appropriate tension ensures that the chain will not jump or slip during transmission, thereby improving transmission efficiency.

[0058] When the picking machine collides with a bale while being towed by a tractor, the weight of the bale presses down on the spring-loaded chain assembly 4. Under the reaction force of the spring, the spring-loaded chain assembly 4 exerts an upward force on the bale, lifting the front part of the bale. The spring-loaded chain then drives the bale upward to the inclined chain 6. The upward thrust of the inclined chain 6 moves the bale upward along the inclined panel 13. Because of the use of the conveying plate 48, the bale is not damaged during transmission. When the bale reaches the top, the horizontal chain 7 pushes the bale along the horizontal panel 12, conveying the bale to the collection platform. This avoids the phenomenon of grass leaves falling and ropes being cut and bales scattering, resulting in a low bale loss rate. This utility model can not only pick up traditional bales (two-rope bales and three-rope bales), but also pick up net bag bales without damage, truly realizing mechanical replacement of manual picking, which not only saves time and labor, but also improves the quality and efficiency of operation.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
