Description

Technical Field

[0001] This utility model belongs to the field of corn harvesting tool manufacturing technology, specifically relating to a corn harvesting tool sharpening assembly. Background Technology

[0002] Corn stalks are relatively thick and resilient. The serrated design of the triangular blades used for shredding increases the contact points and friction with the stalks, allowing them to cut into the stalks more easily and quickly, much like a saw. Compared to smooth blades, this method offers higher cutting efficiency and lower energy consumption. During high-speed rotation, the triangular shape allows the blades to cut and impact the stalks from multiple angles, further pulverizing the cut stalks into smaller particles, resulting in more uniform stalk size and laying the foundation for subsequent shredding.

[0003] During the production of triangular blades for wire reeling, wedge angles of 60-75° are set on both sides of the blade to maintain the strength, heat dissipation, and durability of the saw teeth. After the roughing of the wedge angles, the wedge angles need to be ground. Currently, this is mostly done manually with a hand file. Grinding multiple wedge angles of the triangular blade is not only laborious, but the metal triangular blades and files can also easily scratch the hands of the grinder, thus affecting the grinding operation. Utility Model Content

[0004] The purpose of this invention is to provide a corn harvesting knife sharpening assembly that can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a corn harvester's knife sharpening assembly, including a base plate and two linkage components disposed above the base plate. The base plate is provided with two telescopic support members. Below the two linkage components, there are placement plates for fixing the triangular blades of the shredding saw. The placement plates are disposed on the extended ends of the telescopic support members. A push-up electric push rod is disposed between the base plate and the placement plates. The two placement plates correspond vertically to the two linkage components.

[0007] The two linkage components are symmetrically arranged, and both linkage components are mounted on the frame plate;

[0008] The linkage assembly includes two high-position fixing rods and two low-position fixing rods. Uprights are respectively installed at the four corners of the base plate. Both the high-position fixing rods and low-position fixing rods are mounted on the frame plate. The four corners of the frame plate are respectively connected to the upper sides of the four uprights. Two high-position nuts for clamping the frame plate are threaded onto the high-position fixing rods, and two low-position nuts for clamping the frame plate are threaded onto the low-position fixing rods. Inclined slide rails are rotatably mounted on the lower sides of the high-position fixing rods and low-position fixing rods via hinge seats. Sliding components are installed on the two inclined slide rails, and the inclination direction of the sliding components is parallel and corresponds to the serrations on the triangular blade of the wire-spinning saw.

[0009] The aforementioned corn harvester blade sharpening assembly operates by controlling the extension of the electric push rod via a controller. This causes the coarse serrated triangular blade on the placement plate to move upwards and contact the file on the linkage assembly. Then, the reciprocating electric push rod extends, causing the push-pull plate to slide the entire sliding assembly along the inclined slide rail. Simultaneously, multiple files on the sliding assembly polish the serrated grooves on the serrated triangular blade. As the sliding assembly slides to the low-position fixed rod, the electric push rod retracts, causing the serrated triangular blade on the placement plate to descend away from the file. Then, the reciprocating electric push rod retracts, causing the sliding plate and file to slide towards the high-position fixed rod. At the end point, the electric push rod extends again, pushing the coarse serrated triangular blade on the placement plate upwards to contact the file again. This process continues, improving the polishing effect on the serrations of the coarse serrated triangular blade.

[0010] Preferably, the two high-position fixing rods and the two low-position fixing rods are provided with clamp connecting rods by clamps, and a reciprocating electric push rod is provided between the two high-position fixing rods. The extended end of the reciprocating electric push rod is rotatably provided with a push-pull plate through a hinge seat, and the push-pull plate is connected to the sliding assembly.

[0011] Preferably, the two high-position fixed rods and the reciprocating electric push rod are equipped with clamping and stabilizing rods by means of clamps.

[0012] Preferably, the sliding assembly includes two sliding plates that are slidably mounted on an inclined slide rail and multiple files located between the two sliding plates. The multiple files are engaged in slots on two slotted plates, which are positioned between the two sliding plates.

[0013] Preferably, an elastic rope is provided between the two inclined slide rail rods. One side of the elastic rope is set on the clamp connecting rod on the low fixed rod, and the other side of the elastic rope is set on the slot plate near the low fixed rod.

[0014] Preferably, pressure plates are clamped on both sides above the multiple files, and the pressure plates are connected to the slot plate by screws. The other side of the push-pull plate is rotatably mounted on the pressure plate near the high-position fixing rod via a hinge seat.

[0015] The beneficial effects are:

[0016] This invention uses a reciprocating electric push rod on a linkage component to push a sliding plate to slide back and forth on an inclined slide rail. At the same time, it works in conjunction with a lifting electric push rod to move the coarse serrated triangular blade on the placement plate upward and slide and grind it at a corresponding angle with the file. This can replace manual mechanical reciprocating grinding, improving grinding efficiency and grinding safety. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-3As shown, a corn harvester's knife sharpening assembly includes a base plate 1 and two linkage components 6 disposed above the base plate 1. Two telescopic support members 2 are disposed on the base plate 1. Placement plates 4 for fixing the triangular blades of the shredding saw are respectively disposed below the two linkage components 6. The placement plates 4 are disposed on the extended ends of the telescopic support members 2. A pusher electric push rod 3 is disposed between the base plate 1 and the placement plates 4. The two placement plates 4 correspond vertically to the two linkage components 6 respectively.

[0024] Two linkage components 6 are symmetrically arranged, and both linkage components 6 are set on the frame plate 7. A control device 8 is installed on the bottom plate 1. The control device 8 is equipped with a reciprocating grinding module. The input ends of the lifting electric push rod 3 and the reciprocating electric push rod 69 are electrically connected to the reciprocating grinding module.

[0025] The linkage component 6 includes two high-position fixing rods 61 and two low-position fixing rods 62. The four corners of the base plate 1 are respectively provided with uprights 5. The high-position fixing rods 61 and low-position fixing rods 62 are both provided on the frame plate 7. The four corners of the frame plate 7 are respectively connected to the upper side of the four uprights 5. The high-position fixing rods 61 are threaded with two high-position nuts 61a for clamping the frame plate 7. The low-position fixing rods 62 are threaded with two low-position nuts 62a for clamping the frame plate 7. The lower side of the high-position fixing rods 61 and low-position fixing rods 62 is rotatably provided with inclined slide rails 64 through hinge seats. The two inclined slide rails 64 are provided with sliding components. The inclination direction of the sliding components is parallel and corresponds to the serrations on the triangular blade of the shredding saw.

[0026] As an optional implementation, clamp connecting rods 63 are provided on the two high-position fixing rods 61 and the two low-position fixing rods 62 via clamps. A reciprocating electric push rod 69 is provided between the two high-position fixing rods 61. A push-pull plate 611 is rotatably provided on the extended end of the reciprocating electric push rod 69 via a hinge seat. The push-pull plate 611 is connected to the sliding assembly. With this configuration, the push-pull plate 611 can push and pull the sliding assembly by relying on the reciprocating electric push rod 69, thereby driving the sliding assembly to reciprocate and grind the coarse product of the filament saw blade.

[0027] See attached document Figure 2 and attached Figure 3 Two high-position fixed rods 61 and reciprocating electric push rod 69 are equipped with clamps and a retaining rod 610 is welded on them. This arrangement allows the retaining rod 610 to fix the reciprocating electric push rod 69 between the two high-position fixed rods 61 by means of clamps, thereby enabling the sliding component to be pushed and pulled by power.

[0028] Furthermore, the sliding assembly includes two sliding plates 65 that are slidably mounted on the inclined slide rail 64, and multiple files 67 located between the two sliding plates 65. The multiple files 67 are engaged in slots on two slotted plates 66, which are positioned between the two sliding plates 65. This arrangement allows the multiple files 67 to simultaneously grind the serrations on the coarse filament saw blade, improving grinding efficiency.

[0029] Furthermore, an elastic rope 612 is provided between the two inclined slide rail rods 64. One side of the elastic rope 612 is set on the clamp connecting rod 63 on the lower fixed rod 62, and the other side of the elastic rope 612 is set on the slot plate 66 near the lower fixed rod 62. This arrangement allows the elastic rope 612 to be stretched and elastically contracted when the sliding component slides close to the upper fixed rod 61. This allows the elastic rope to pull the sliding component towards the lower fixed rod 62 when the reciprocating electric push rod 69 extends, thus accommodating the reciprocating movement of the sliding component.

[0030] Furthermore, pressure plates 68 are clamped on both sides above the multiple files 67. The pressure plates 68 are connected to the slot plate 66 by screws. The other side of the push-pull plate 611 is rotatably mounted on the pressure plate 68 near the high-position fixing rod 61 via a hinge seat. This arrangement not only clamps and constrains the files 67 on the slot plate 66, but also facilitates the replacement of the files 67 by removing the screws.

[0031] Using the above structure, the specific steps of the reciprocating grinding module are as follows: the controller controls the extension of the pusher electric push rod 3, which simultaneously moves the coarse serrated triangular blade on the placement plate 4 upward to contact the file 67 on the linkage component 6. Then, the controller controls the extension of the reciprocating electric push rod 69, which moves the push-pull plate 611 to push the sliding component to slide along the inclined slide rail 64. At the same time, the multiple files 67 on the sliding component slide and grind the serrated grooves on the serrated triangular blade. Then, as the sliding component slides to the low fixed rod 62, the controller controls the extension of the pusher electric push rod 3 to retract, thereby moving the serrated triangular blade on the placement plate 4 downward away from the file 67. Then, the reciprocating electric push rod 69 retracts, moving the sliding plate and the file 67 to the high fixed rod 61. When they reach the end point, the controller controls the extension of the pusher electric push rod 3 again, thereby moving the coarse serrated triangular blade on the placement plate 4 upward to contact the file 67 again. In this way, the grinding process can continue, which can improve the grinding effect on the serrations of the coarse serrated triangular blade.
