Description

Technical Field

[0001] The invention relates to the technical field of straw bale collecting machinery, in particular to an inclined straw bale picking machine. Background Art

[0002] With the advancement of agricultural integration, more and more agricultural operations adopt mechanized processing methods. The mechanized operation of bale picking and stacking is to use machinery to bundle crops such as forage grass, rice and wheat straw into bales, and then the machinery completes all processes such as picking, loading, transporting and stacking, thus replacing the heavy manual picking and stacking work.

[0003] However, the existing bale picking machines for completing bale picking operations have at least the following defects and deficiencies: the picking machine uses chain drive to transport the bales to the collection platform. During the collection process of alfalfa bales and straw bales, the chain directly contacts the bales, which will cause the grass leaves to fall off and the rope to be cut and the bales to be scattered, resulting in a high bale loss rate. In particular, alfalfa, as a concentrate, has a higher protein content in its leaves than in the straw stalks, and its sales value mainly depends on the amount of grass leaves in each bale. It is especially not suitable for straw net bag bales and wheat straw net bag bales, which have short fibers and low moisture content. It is difficult or even impossible for existing picking machines to pick up straw net bag bales and wheat straw net bag bales. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an angled bale picker, which can not only pick up traditional bales (two-rope bales and three-rope bales), but also pick up net bag bales without damage.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An angled bale picking machine comprises a machine body, a spring-tooth chain assembly, an angled chain and a horizontal chain; the machine body is provided with an angled panel inclined downward, and the angled chain is installed on the angled panel; a horizontal panel is provided on the top of the angled panel, and the horizontal chain is installed on the horizontal panel, and the spring-tooth chain assembly is arranged at the bottom of the angled chain; the spring-tooth chain assembly, the angled chain and the horizontal chain are all provided with grass transport plates, and the spring-tooth chain assembly is provided with a spring; the spring-tooth chain assembly lifts the bale from the ground to the angled panel, the inclined chain moves the bale up to the horizontal panel, and the horizontal chain transfers the bale to a collecting platform.

[0007] Furthermore, the grass transporting board is an acute-angled triangular board, and the grass transporting board is 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 tooth chain assembly to apply downward pressure to the straw bale.

[0009] Furthermore, the pressure plate device includes a pressure plate, a bracket, a rotating shaft, a limit plate and a tension spring; the pressure plate and the limit plate are installed on the rotating shaft, the rotating shaft is hinged on the bracket, one end of the tension spring is connected to the limit 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 inner side 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 body, and the torsion spring is installed on the column.

[0012] Furthermore, the spring tooth chain assembly includes a support frame, a sprocket frame, a main shaft, a driving sprocket, a driving sprocket, a driven sprocket and a chain; the support frame, the sprocket frame, the driving sprocket and the driving sprocket are installed on the main shaft, the driven sprocket is installed on the sprocket frame, the chain is installed on the driving sprocket and the driven sprocket, the support frame is connected to the body, and the sprocket frame is connected to the body through a spring.

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

[0014] Furthermore, it also includes a non-return hook and a non-return spring. The non-return hook is hinged on the guide plate. One end of the non-return spring is connected to the non-return hook, and 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 the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with an angled panel, a horizontal panel, a horizontal chain, an angled chain and an elastic tooth chain assembly. The elastic tooth chain assembly, the angled chain and the horizontal chain are all provided with a grass transporting plate, and the elastic tooth chain assembly is provided with a spring. When the picker collides with a straw bale while being towed by a tractor, the weight of the straw bale presses on the elastic tooth chain assembly. Under the reaction force of the spring, the elastic tooth chain assembly exerts an upward force on the straw bale, which bounces up the front end of the straw bale, and then the elastic tooth chain drives the straw bale upward to the angled panel. The angled chain drives the straw bale to move upward along the angled panel. When the straw bale reaches the top, the horizontal chain drives the straw bale to move horizontally along the horizontal panel to the collection platform. The grass transporting plate on the chain of the present invention pushes the straw bale to move along the angled panel and the horizontal panel. The straw bale moves on the panel instead of on the chain, which avoids the phenomenon of grass leaves falling off and the bale being scattered when the rope is cut, and the straw bale loss rate is low. The present invention can not only pick up traditional bales (two-line bales and three-line bales), but also can pick up net bag bales without damage, truly realizing the replacement of manual picking by machinery, which not only saves time and labor, but also improves work quality and efficiency.

[0018] 2. The grass transport board of the present invention adopts a special star-shaped rotating board, which will not damage the grass bale during the transmission process.

[0019] 3. The present invention is provided with a torsion spring guide device to ensure that the straw bale moves along the panel. When the straw bale reaches the top, it is driven by the torsion spring guide device to rotate 90 degrees in the direction of the travel and transported horizontally toward the platform along the direction of the connecting arm, thereby transferring the straw bale to the platform.

[0020] 4. The present invention is provided with a pressure plate device, which mainly plays a limiting role. Under the action of the spring tooth chain, the straw bale will not separate from the inclination panel when it bounces upward, and the tension spring plays a resetting role. Every time the flying straw bale is lifted up, it is pulled by the tension spring and exerts a downward pressure on the straw bale in the reverse direction, ensuring that the straw bale does not separate from the inclination panel and runs upward smoothly.

[0021] 5. The first guide plate and the second guide plate of the oil cylinder clamping mechanism of the present invention are symmetrically arranged to form an eight-shaped shape; the guide plates play a role in guiding and correcting the straw bales during the picking process.

[0022] 6. The non-return hook of the oil cylinder clamping mechanism of the present invention can effectively prevent the bale from moving backward during the picking process.

[0023] 7. The present invention is provided with a guide roller, which can rotate in the same direction as the straw bale when the straw bale turns 90 degrees, playing a guiding role and reducing resistance.

[0024] 8. In the picking process of the present invention, the straw bale is clamped by the oil cylinder clamping mechanism, which will not cause damage to the straw bale, and can ensure that the nutrients of the straw leaves of the straw bale will not be lost due to the damage to the straw leaves during the picking process.

[0025] 9. The present invention is provided with a chain tensioning device for tensioning the chain, which can ensure that the chain maintains an appropriate tightness during the transmission process, avoiding the chain being too loose, resulting in a decrease in transmission efficiency and an increase in energy consumption, and the chain being too tight, resulting in wear and damage. Appropriate tension can ensure that the chain will not jump or slip during the transmission process, thereby improving the transmission efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings:

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

[0044] like Figure 5 As shown, the machine body 1 includes a machine body support 11, a horizontal panel 12, a tilt panel 13 and a connecting arm 14, and the machine body 1 is connected to the tractor and the collection platform through the connecting arm 14. The horizontal panel 12 is arranged horizontally, and the tilt panel 13 is arranged tilted downward, with the top end connected to the right end of the horizontal panel 12, and the left end of the horizontal panel 12 is connected to the connecting arm 14, and the machine body support 11 is located at the bottom end of the tilt panel 13. The angle between the tilt panel 13 and the horizontal panel 12 is the tilt angle of the tilt picker. A groove is provided in the middle of the horizontal panel 12, and the horizontal chain 7 is installed in the groove. A groove is provided in the middle of the tilt panel 13, and the tilt chain 6 is installed in the groove. The motor drives the spring tooth chain assembly 4, the tilt chain 6, and the horizontal chain 7 to operate synchronously.

[0045] The guide roller 8 is arranged vertically with its axis line mounted inside the corner of the horizontal panel 12 and the angled panel 13. When the bale turns at 90 degrees, the guide roller 8 can rotate in the same direction as the bale to play a guiding role and reduce resistance.

[0046] In this embodiment, two torsion spring guide devices 3 are provided, which are respectively installed on the outside of the tilt panel 13 and the outside of the horizontal panel 12. The 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 installed on the column 32. The guide torsion spring 31 is provided with a stop arm, and the stop arm of the guide torsion spring installed on the outside of the tilt panel 13 is parallel to the tilt panel 13, and the stop arm of the guide torsion spring installed on the outside of the horizontal panel 12 is parallel to the horizontal panel 12.

[0047] When the bale reaches the top, the torsion spring guide device 3 drives the horizontal chain 7 to rotate 90 degrees in the direction of the travel and transport the bale horizontally toward the platform along the direction of the connecting arm, thereby transferring the bale to the platform.

[0048] like Figure 6 As shown, the pressure plate device 2 is installed above the spring tooth chain assembly 4 to apply downward pressure to the straw bale. 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 installed on the rotating shaft 23, the pressure plate 21 is located in the middle of the rotating shaft 23, and the two limiting plates 24 are located at both ends of the rotating shaft 23. The two ends of the rotating shaft 23 are hinged to the bracket 22 through bearings. One end of the tension spring 25 is connected to the tension spring hook 251 on the limiting plate 24, and the other end is connected to the 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 play a role of limiting and buffering. The bracket 22 is connected to the body 1 through a U-bolt, and the height of the pressure plate 21 is adjusted by adjusting the height of the U-bolt. The tension spring 25 plays a resetting role. Every time the flying grass bale is lifted up, the tension of the tension spring 25 exerts a downward pressure on the grass bale in the reverse direction, ensuring that the grass bale does not separate from the inclination 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 driving sprocket 44, an active sprocket 45, a driven sprocket 46, a chain 47, a grass transporting plate 48 and a tension spring 25.

[0050] The support frame 41, the sprocket frame 42, the driving sprocket 44 and the driving sprocket 45 are installed on the main shaft 43. The driving sprocket 44 is connected to the motor through a chain drive. The motor drives the driving sprocket 44 to rotate, thereby driving the driven sprocket 46 and the chain 47 to operate. A tension spring hook 251 is provided on the sprocket frame 42. 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 grass transport board 48 is a right triangle, one angle is 30 degrees, the other angle is 60 degrees, and the right angle is connected to the chain 47, and the 30 degree angle is set upward. The grass transport board 48 is evenly distributed and installed on the chain 47 to form a star-shaped rotating plate, which ensures that the grass bale is not damaged during the transmission process.

[0052] The motor drives the driving sprocket 44 to rotate, and then drives the driven sprocket 46 and the chain 47 to operate to lift the grass bale upward, thereby lifting the grass bale from the ground to the inclined panel 13.

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

[0054] The first guide plate 51 and the second guide plate 52 are hinged at the bottom end of the machine body 1. The first guide plate 51 and the second guide plate 52 are symmetrically arranged to form an eight-shaped 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 straw bale.

[0055] The guide plate guides and corrects the bale during the picking process. The bale is clamped by the oil cylinder clamping mechanism 5 during the picking process, which will not cause damage to the bale, and can ensure that the nutrients of the bale grass leaves will not be lost due to damage to the grass leaves during the picking process.

[0056] The anti-return hook 54 is hinged on the inner side of the first guide plate 51 and the second guide plate 52. The anti-return hook 54 is an acute triangle and is inclined toward the grass transport direction. The arrow indicates the grass transport direction. One end of the anti-return spring 55 is connected to the anti-return hook 54, and the other end is connected to the guide plate. The anti-return hook 54 can prevent the grass bale from moving backward during the picking process. When the grass bale moves along the grass transport direction and touches the anti-return hook 54, the anti-return hook 54 is driven to rotate, the anti-return spring 5 is stretched, the grass bale leaves the anti-return hook 54, and is reset under the action of the elastic force of the anti-return spring 55. If the movement direction of the grass bale is opposite to the grass transport direction, the anti-return hook 54 will prevent the grass bale from moving forward. The anti-return hook 54 can effectively prevent the grass from retreating.

[0057] like Fig.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 on the machine 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 on the bottom of the tensioning bracket 91; the roller 93 contacts the chain 47 and lifts the chain 47 with the force provided by the torsion spring. The chain tensioning device 9 tensions the chains in the spring tooth chain assembly 4, the angle chain 6, and the horizontal chain 7. To ensure that the chain maintains appropriate tightness during the transmission process, to avoid the chain being too loose, resulting in a decrease in transmission efficiency and an increase in energy consumption, as well as wear and damage caused by the chain being too tight. Appropriate tension can ensure that the chain will not jump or slip during the transmission process, thereby improving the transmission efficiency.

[0058] When the picker collides with a bale while being towed by a tractor, the weight of the bale presses on the spring-tooth chain assembly 4. Under the reaction force of the spring, the spring-tooth chain assembly 4 exerts an upward force on the bale, which bounces up the front end of the bale, and then the spring-tooth chain drives the bale upward to the angle chain 6. The upward thrust of the angle chain 6 drives the bale to move up along the angle panel 13. Since the grass transport plate 48 is adopted, the bale will not be damaged during the transmission process. When the bale reaches the top, the horizontal chain 7 pushes the bale to move along the horizontal panel 12 and transfers the bale to the collection platform. The phenomenon of grass leaves falling and the loosening of the bale due to rope cutting is avoided, and the loss rate of the bale is low. The present invention can not only pick up traditional bales (two-rope bales and three-rope bales), but also can pick up net bag bales without damage, truly realizing the replacement of manual picking by machinery, which not only saves time and labor, but also improves the quality and efficiency of work.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
