Abstract
Description
Technical Field
[0001] This utility model relates to the field of hay bale collection machinery technology, specifically to a feeding device for 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, the feeding devices of existing bale pickers have at least the following defects and shortcomings: 1. Lifting bales from the ground to the inclined panel is laborious, and the chain directly contacts the bales, causing grass leaves to fall off, ropes to be cut, and bales to scatter, resulting in a high bale loss rate. Alfalfa, as a concentrated feed, has a higher protein content in its grass leaves than in its stalks, and its market value depends mainly on the amount of grass leaves in each bale. It is particularly unsuitable for straw mesh bag bales and wheat straw mesh bag bales, as these have short fibers and low moisture content, making it difficult, or even impossible, for existing pickers to pick them up. 2. Bales easily detach from the inclined panel. 3. It cannot guide or correct the bales. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a feeding device for an inclined bale picker, which can lift bales from the ground to the inclined panel without damage, making it difficult for the bales to fall off the inclined panel, and can also guide and correct the bales.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A feeding device for an angled hay bale picker includes a machine body and a spring-tooth chain assembly, a pressure plate device, and a hydraulic cylinder clamping mechanism mounted on the machine body. The machine body has an angled panel that slopes downwards. The spring-tooth chain assembly and the hydraulic cylinder clamping mechanism are located at the bottom end of the angled panel, and the pressure plate device is located above the spring-tooth chain assembly. The spring-tooth chain assembly includes a support frame, a sprocket frame, a main shaft, a drive sprocket, a driving sprocket, a driven sprocket, a chain, and a hay conveying plate. 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, the sprocket frame is connected to the machine body via a spring, and the hay conveying plate is mounted on the chain.
[0007] The spring chain assembly lifts the bales from the ground onto the angled panel, the pressure plate device ensures that the bales do not detach from the angled panel, and the hydraulic cylinder clamping mechanism guides and corrects the bales.
[0008] 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.
[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, the hydraulic cylinder clamping mechanism includes a guide plate and a hydraulic cylinder. The guide plate is hinged to the bottom of the machine body. The guide plate includes a first guide plate and a second guide plate, which 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 of straw.
[0011] 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.
[0012] 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.
[0013] Compared with existing technologies, the beneficial effects of this utility model are:
[0014] 1. This utility model includes a machine body and a spring-tooth chain assembly, a pressure plate device, and a hydraulic cylinder clamping mechanism installed on the machine body. When the pickup machine collides with a bale of grass during its movement while being towed by a tractor, the weight of the bale presses down on the spring-tooth chain assembly. Under the reaction force of the spring, the spring-tooth chain assembly exerts an upward force on the bale, lifting the front end of the bale. The spring-tooth chain then drives the bale upward to the inclined panel. The pressure plate device mainly serves as a limit device, ensuring that the bale does not detach from the inclined panel when it bounces upward under the action of the spring-tooth chain. The tension spring acts as a reset device, applying downward pressure to the bale each time it is lifted by a flying bale, ensuring that the bale does not detach from the inclined panel and moves smoothly upward. The first guide plate and the second guide plate of the hydraulic cylinder clamping mechanism of this utility model are symmetrically arranged in a V-shape; the guide plates guide and correct the bale during the pickup process.
[0015] 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.
[0016] 3. 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.
[0017] 4. 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.
[0031] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:
[0032] like Figure 1 As shown, an inclined bale picker includes a body 1 and a feeding device, a torsion spring guide device 3, an inclined chain 6, a horizontal chain 7 and a guide roller 8 installed on the body.
[0033] A feeding device for an angled hay bale picker includes a pressure plate device 2, a spring tooth chain assembly 4, a hydraulic cylinder clamping mechanism 5, and a chain tensioning device 9.
[0034] like Figure 1 , Figure 2 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.
[0035] like Figure 3 As 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.
[0036] like Figure 4 , Figure 5 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] like Figure 1 and 6 As shown in Figure 8, 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] like Figure 9 , 10As 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. The roller 93 is hinged to the bottom of the tensioning bracket 101. 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.
[0045] When the pickup machine collides with a bale while being towed by the 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 angled chain 6. The upward thrust of the angled chain 6 moves the bale upward along the angled panel 13. Because of the use of the conveying plate 48, the bale will not be damaged during transmission. The spring-loaded chain assembly 4 can lift the bale from the ground to the angled panel without damage. The pressure plate device 2 makes it difficult for the bale to fall off the angled panel, and the hydraulic cylinder clamping mechanism 5 can guide and correct the bale.
[0046] 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.
