Description

Technical Field

[0001] This utility model belongs to the field of harvester blade processing technology, and in particular relates to a feeding device for harvester blade sharpening. Background Technology

[0002] Harvesters are increasingly used in modern agriculture, especially for rice. The area where rice is harvested using harvesters now accounts for over 80% of the rice planting area. During operation, the most easily worn part of a rice harvester is the blade. Encountering hard objects such as stones and tree roots during cutting can loosen or deform the blade guard, causing uneven blade height. Loose rivets and collisions during cutting can also damage the cutting blade. Harvester blades are made of cast steel, and the typical processing method for these blades is simply sharpening and grinding the cutting edge before use. Blade sharpening is an important skill widely used in machining, manufacturing, and daily life to ensure the performance, lifespan, and processing efficiency of the cutting tools.

[0003] Harvester blades are processed in batches, and the successive sharpening of multiple blades requires multiple feeding operations. Therefore, a feeding device for harvester blade sharpening is needed, which can provide feeding for multiple cycles with a single feeding, thereby reducing the number of feeding operations, simplifying the operation steps, and improving the feeding efficiency during harvester blade sharpening.

[0014] In the following description, embodiments of the harvester blade sharpening feeding device of the present invention will be described with reference to the accompanying drawings.

[0015] Example 1: Figure 1-4 This invention illustrates a feeding device for sharpening harvester blades according to an embodiment of the present invention. It includes a movable carrier plate 1. A storage trough 2 and a base plate 3 are bolted to the top of the movable carrier plate 1. A pressing assembly 4 is mounted on the top of the base plate 3. Blades 5 are disposed within the inner cavity of the storage trough 2. A horizontal plate 6 is welded to the right side of the movable carrier plate 1. Two symmetrically arranged turntables 7 are rotatably connected to the top of the horizontal plate 6. A motor 8 is bolted to the bottom of the horizontal plate 6. The output shaft of the motor 8 is fixedly connected to the turntables 7. A belt 9 is driven to the surface of the turntables 7. A clamping block 10 is bolted to the surface of the belt 9. A strip plate 11 is fixedly connected to the top of the clamping block 10. A rectangular plate 12 is fixedly connected to the left side of the strip plate 11. The rectangular plate 12 is slidably connected to the movable carrier plate 1. A groove adapted to the rectangular plate 12 is provided on the right side of both the storage trough 2 and the base plate 3. The rectangular opening has an infrared sensor 13 bolted to the top of the movable carrier plate 1. A processing table 14 is installed at the bottom of the movable carrier plate 1. A sharpening assembly 15 is installed on the top of the processing table 14 and a control box 16 is bolted to it. An indicator light tube 17 is bolted to the top of the control box 16. A guide plate 18 is bolted to the top of the processing table 14. The guide plate 18 guides the sharpened blades that are pushed down, making it easier to collect the sharpened blades. The surface of the belt 9 has an integrally formed protrusion 22 that fits against the inner wall of the clamping block 10. The protrusion 22 increases the friction between the belt 9 and the clamping block 10, preventing relative displacement between them when the belt 9 moves the clamping block 10, thus improving the stability of the connection between them.

[0016] Example 2: Figure 1-4This invention illustrates a feeding device for sharpening harvester blades according to an embodiment of the present invention. It includes a movable carrier plate 1. A storage trough 2 and a base plate 3 are bolted to the top of the movable carrier plate 1. A pressing assembly 4 is mounted on the top of the base plate 3. Blades 5 are disposed within the inner cavity of the storage trough 2. A horizontal plate 6 is welded to the right side of the movable carrier plate 1. Two symmetrically arranged turntables 7 are rotatably connected to the top of the horizontal plate 6. A motor 8 is bolted to the bottom of the horizontal plate 6. The output shaft of the motor 8 is fixedly connected to the turntables 7. A belt 9 is driven through the surface of the turntables 7. A clamping block 10 is bolted to the surface of the belt 9. A strip plate 11 is fixedly connected to the top of the clamping block 10. A rectangular plate 12 is fixedly connected to the left side of the strip plate 11. An infrared sensor 13 is bolted to the top of the movable carrier plate 1. A processing table 14 is mounted at the bottom of the movable carrier plate 1. A sharpening assembly 15 is installed on the top of the platform 14 and a control box 16 is fixedly connected to it with bolts. An indicator light tube 17 is fixedly installed on the top of the control box 16 with bolts. A cover 19 is fixedly connected to the top of the horizontal plate 6 with bolts. The cover 19 is slidably connected to the strip plate 11. The cover 19 protects the outside of the turntable 7 and the belt 9, preventing them from biting into foreign objects during operation, thereby improving the smoothness of the device operation. A limit slide rod 20 is welded to the top of the horizontal plate 6. A slider 21 is slidably connected to the surface of the limit slide rod 20. The slider 21 is fixedly connected to the clamping block 10. The movement of the clamping block 10 is limited by the cooperation of the limit slide rod 20 and the slider 21, preventing the clamping block 10 from shaking during movement, thereby improving the stability of the clamping block 10 during movement.

[0017] Working principle: When using this utility model, the user turns on the motor 8 to drive the turntable 7 to rotate. At this time, the belt 9 drives the clamping block 10 to move back and forth, so that the clamping block 10 drives the rectangular plate 12 to move through the strip plate 11. This causes the rectangular plate 12 to push the blade 5 at the bottom of the storage tank 2 through the bottom cavity of the base plate 3 to the bottom of the pressing assembly 4. Then, the pressing assembly 4 fixes the blade 5. At this time, the sharpening assembly 15 sharpens the blade 5. The sharpening position of the blade 5 can be changed by moving the horizontal movement of the moving carrier plate 1. Then refer to the above steps. The rectangular plate 12 moves again to load the blades 5 into the storage trough 2 and pushes the sharpened blades 5 down, so that the old and new blades 5 can be replaced. With the infrared sensor 13, when the blades 5 in the storage trough 2 have finished processing, a material shortage signal is transmitted to the control box 16, so that the control box 16 controls the indicator light tube 17 to flash as an alarm, so that the staff can replenish the material. This achieves the goal of using a single loading for multiple cycles, thereby reducing the number of loading times, simplifying the operation steps, and improving the loading efficiency of harvester blade sharpening.

[0018] In summary, the feeding device for sharpening harvester blades uses a belt 9 to drive the clamping block 10 to move back and forth. This causes the clamping block 10 to move the rectangular plate 12 via the strip plate 11. Consequently, the rectangular plate 12 moves the blade 5 at the bottom of the storage trough 2. This allows for multiple cycles of use with a single feeding, thereby reducing the number of feeding cycles, simplifying the operation steps, and improving the feeding efficiency during harvester blade sharpening.
