Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a grain harvesting device for wheat breeding. Background Technology

[0002] In wheat breeding, ear harvesting is a crucial step, and its precision directly affects the subsequent breeding results and seed quality. Traditional harvesting methods typically rely on general-purpose harvesters; however, these harvesters have significant limitations when applied to wheat breeding.

[0003] First, general-purpose harvesters have a wide harvesting range, making it difficult to precisely target a single row or specific ear row during harvesting. This can easily lead to the harvesting of adjacent wheat ears, resulting in mixing of different wheat varieties and significantly impacting breeding purity. Furthermore, traditional harvesters are bulky, complex in structure, and lack operational flexibility, making them difficult to move freely within the limited space of breeding experimental fields. Their operation is also complex, requiring specialized personnel and resulting in high operating costs. Utility Model Content

[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a wheat ear harvesting device. By adjusting the components to control the rotation of gears, the first and second cutting blades are driven to move relative to each other, which can accurately cut a single row or a specific wheat ear, effectively avoiding the mixing of different wheat varieties and ensuring the purity of the breeding.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A wheat ear-row harvesting device for wheat breeding includes a harvesting blade holder with a first and a second cutting blade. A connecting rod is provided at the bottom of both the first and second cutting blades. A groove is formed on the harvesting blade holder, and the connecting rod passes through the groove and extends to the bottom of the harvesting blade holder. A toothed plate is fixedly connected to the bottom end of the connecting rod, with the tooth surfaces of the two toothed plates close to each other. A gear is movably mounted at the bottom of the harvesting blade holder, and both toothed plates are meshed with the gear. An adjusting assembly for adjusting the gear is provided at the bottom of the harvesting blade holder. The connecting rod is a square rod, and its outer surface fits against the groove.

[0007] More preferably, guide plates are symmetrically arranged on the harvester blade holder, and the guide plates are slidably connected to the harvester blade holder. Guide rods are symmetrically arranged at the bottom of the harvester blade holder, and guide cylinders are sleeved on the outside of the guide rods. The guide cylinders are fixedly installed at the bottom of the guide plates.

[0008] More preferably, a screw block is fixedly connected to the top of the guide plate, and a screw rod is provided between the two guide plates. The screw rod is threadedly connected to the screw block, and the screw rod is a double-threaded screw rod.

[0009] More preferably, both the first cutting blade and the second cutting blade include a fixed blade and a movable blade. A clamping member is fixedly disposed on the fixed blade. The fixed blade and the movable blade are slidably connected. A driving component is disposed on the fixed blade. The driving component is used to drive the movable blade to reciprocate.

[0010] More preferably, the adjusting component includes a worm gear, which is fixedly installed at the bottom of the gear. A connecting cylinder is fixedly connected to the bottom of the harvester blade holder. A drive rod rotates through the inside of the connecting cylinder.

[0024] like Figure 1-4 As shown, a wheat ear harvesting device for wheat breeding includes a harvesting blade holder 1, on which a first cutting blade 2 and a second cutting blade 3 are provided. A connecting rod 4 is provided at the bottom of both the first cutting blade 2 and the second cutting blade 3. A sliding groove 5 is provided on the harvesting blade holder 1, through which the connecting rod 4 passes and extends to the bottom of the harvesting blade holder 1. A toothed plate 6 is fixedly connected to the bottom end of the connecting rod 4, with the tooth surfaces of the two toothed plates 6 close to each other. A gear 7 is movably installed at the bottom of the harvesting blade holder 1, and both toothed plates 6 are meshed with the gear 7. An adjusting component for adjusting the gear 7 is provided at the bottom of the harvesting blade holder 1.

[0025] The harvester blade holder 1 is symmetrically provided with guide plates 9, which are slidably connected to the harvester blade holder 1. The bottom of the harvester blade holder 1 is symmetrically provided with guide rods 10, and a guide cylinder 11 is sleeved on the outside of the guide rods 10. The guide cylinder 11 is fixedly installed on the bottom of the guide plate 9.

[0026] A screw block 12 is fixedly connected to the top of the guide plate 9, and a screw 13 is arranged between the two guide plates 9. The screw 13 is threadedly connected to the screw block 12, and the screw 13 is a double-threaded screw 13. The sliding connection between the guide plate 9 and the harvester's blade holder 1, as well as the design of the double-threaded screw 13, allow the device to be flexibly adjusted according to the spacing of different wheat ear rows, adapting to different experimental field environments. At the same time, the overall structure of the device is relatively simple and the size is small, making it easy to move and operate within the limited space of the breeding experimental field.

[0027] The first cutting blade 2 and the second cutting blade 3 both include a fixed blade 14 and a movable blade 15. A clamping member 16 is fixedly disposed on the fixed blade 14. The fixed blade 14 and the movable blade 15 are slidably connected. A driving assembly 17 is disposed on the fixed blade 14. The driving assembly 17 is used to drive the movable blade 15 to reciprocate.

[0028] The adjusting assembly 8 includes a worm gear 18, which is fixedly mounted on the bottom of the gear 7. A connecting cylinder 19 is fixedly connected to the bottom of the harvester's blade holder 1. A drive rod 20 rotates through the interior of the connecting cylinder 19. A worm 21 is fixedly connected to one end of the drive rod 20, and the worm 21 is drively connected to the worm gear 18. The adjusting assembly can be an electric rocker arm mechanism.

[0029] The other end of the drive rod 20 is fixedly connected to a hexagonal head 22, which extends to the side of the harvester blade holder 1. Operators can easily adjust the cutting blade by simply rotating the hexagonal head 22 using a wrench or other tools, eliminating the need for professional personnel and reducing operating costs.

[0030] Working principle:

[0031] Adjusting the spacing of guide plates 9: Based on the spacing of the wheat ear rows, use a tool to rotate the double-threaded screw 13. Since the screw 13 is double-threaded, when the screw 13 is rotated, the two guide plates 9 will move relative to or away from each other along the screw 13, thereby adjusting the distance between the guide plates 9 to adapt to different widths of wheat ear rows.

[0032] Adjusting the cutting blade: Use a wrench or other tools to turn the hexagonal head 22. The hexagonal head 22 drives the drive rod 20 to rotate, and the worm 21 at one end of the drive rod 20 rotates accordingly. The worm 21 is connected to the worm wheel 18, thereby driving the worm wheel 18 and the gear 7 to rotate. When the gear 7 rotates, the two toothed plates 6 meshing with the gear 7 will move relative to or away from each other, thereby driving the first cutting blade 2 and the second cutting blade 3 to move relative to each other, adjusting the cutting width so that it is aligned with the part of the wheat ear to be cut.

[0033] The drive assembly 17 on the fixed blade 14 is activated, and the drive assembly 17 drives the movable blade 15 to reciprocate relative to the fixed blade 14. During the cutting process, the clamping member 16 on the fixed blade 14 will limit and clamp the movable blade 15, and then the reciprocating cutting action of the movable blade 15 will separate the wheat ears from the stalk, completing the precise ear harvesting operation.
