Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and more specifically, relates to a feed rate regulating device for seed drills. Background Art

[0002] A seeder is a planting machine that sows crop seeds. It is mainly used to automatically sow or plant crop seeds or planting materials in the soil to meet specific agronomic requirements. At present, during the sowing process, the seeder uses a grooved wheel seed meter to feed the seed particles inside the hopper into the seed tube in a circular manner, so as to sow at equal intervals. However, in the actual agricultural planting process, the sowing amount of crop seeds varies for different crop seeds or planting soil areas. The groove wheel structure of the traditional grooved wheel seed meter is fixed, resulting in a fixed seed capacity inside the groove of the grooved wheel seed meter. It can be seen that during the seed sowing process, the traditional seeder cannot flexibly adjust the feeding capacity according to the seed sowing amount requirements, making it impossible to adapt the seed sowing amount to the sowing in different planting soil areas. This not only results in seed waste, but also affects the cultivation and growth quality of agricultural crops in the land. Utility Model Content

[0027] In the embodiment of the present disclosure, the seeding groove wheel 308 is a disc-shaped structure, and a through hole is provided at the center position of the seeding groove wheel 308, and eight groups of open grooves are provided on the outer side surface of the seeding groove wheel 308. The seeding groove wheel 308 is opposite to the through grooves at the top and bottom ends of the outer side surface of the casing 301. During the rotation of the seeding groove wheel 308, the grooves of the seeding groove wheel 308 pass through the through grooves at the top of the outer side surface of the casing 301, and the grooves of the seeding groove wheel 308 receive the seeds in the storage hopper 1. The grooves of the seeding groove wheel 308 pass through the through grooves at the bottom of the outer side surface of the casing 301. The seeds in the grooves of the seeding groove wheel 308 rely on gravity to be sprinkled toward the seeding tube 2, completing the feeding and conveying work of the seeding groove wheel 308, and a through hole is provided at the center position of the bottom of each group of grooves.

[0028] In the embodiment of the present disclosure, there are eight groups of seed-carrying plates 309, which are respectively embedded in eight groups of grooves of the seed-seeding groove wheel 308. The lower side of each group of seed-carrying plates 309 is provided with a convex column structure, and the convex columns on the lower side of the seed-carrying plates 309 are inserted into the groove through holes of the seed-seeding groove wheel 308.

During the rotation of the threaded adjustment rod 304, the pushing block 310 is driven to move left or right, so that the curved cone structure of the pushing block 310 synchronously pushes the convex columns of the eight groups of seed-carrying plates 309 to move in a directional manner along the bottom through hole of the groove of the seeding groove wheel 308, so that the pushing block 310 can simultaneously adjust the seed-carrying capacity of the eight groups of grooves of the seeding groove wheel 308.

[0030] In the embodiment of the present disclosure, a circular groove is provided at the center position of the left side of the rotating wheel 306, and an internal tooth structure is provided on the inner wall of the groove. The driving gear 305 is meshed and connected to the internal tooth structure on the inner side surface of the circular groove of the rotating wheel 306. The driving gear 305 drives the seed-discharging groove wheel 308 welded to the rotating wheel 306 to rotate synchronously through the internal tooth structure on the inner side surface of the circular groove of the rotating wheel 306, thereby completing the circular rotation and transportation of seeds from the top groove of the shell 301 to the bottom groove of the shell 301.

[0031] In the embodiment of the present disclosure, a circular groove is provided on the left side of the guide sleeve 307, and two groups of long sliding grooves are provided on the inner wall of the circular groove of the guide sleeve 307. The convex structure of the pushing block 310 is embedded in the long sliding groove of the guide sleeve 307, so that the pushing block 310 can be guided and moved left and right along the long sliding groove of the guide sleeve 307.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When the seed feeding capacity of the seeding groove wheel 308 is adjusted, the adjusting knob 302 is manually turned, and the adjusting knob 302 drives the threaded adjusting rod 304 to rotate. Since the outer side of the threaded adjusting rod 304 is threadedly engaged with the threaded through hole of the pushing block 310, the threaded adjusting rod 304 drives the pushing block 310 to move left or right along the long slide groove of the guide sleeve 307. If it is necessary to reduce the seed sowing amount, the threaded adjusting rod 304 drives the pushing block 310 to move left or right. 308, and the seeding wheel 308 is moved to the upper groove of the seeding groove wheel 308, thereby reducing the space capacity of the groove of the seeding groove wheel 308, thereby reducing the seed carrying capacity in the groove of the seeding groove wheel 308. If the seed sowing amount needs to be increased, the threaded adjusting rod 304 drives the pushing block 310 to move to the right, and the seeding plate 309 is pulled in the groove of the seeding groove wheel 308. Under the elastic tension of the pulling spring 311, the bottom ends of the convex columns of the eight groups of seed-carrying plates 309 fit the arc-conical structure of the left end of the pushing block 310 and move synchronously toward the central axis of the pushing block 310. At this time, the seed-carrying plates 309 move along the groove bottom through-hole of the groove of the seed-planting groove wheel 308 toward the groove bottom of the groove of the seed-planting groove wheel 308, increasing the groove space capacity of the seed-planting groove wheel 308, thereby increasing the seed carrying capacity in the groove of the seed-planting groove wheel 308. When the seed-planting groove wheel 308 is feeding the seeds, the motor 3 03 drives the driving gear 305 to rotate, and the driving gear 305 drives the rotating wheel 306 to rotate through the internal tooth structure of the rotating wheel 306, and the rotating wheel 306 drives the seeding groove wheel 308 welded on the right end to rotate. During the rotation of the seeding groove wheel 308, the seeds in the groove are transported from the storage hopper 1 bolted at the top through groove on the outer side of the casing 301 to the seeding tube 2 bolted at the bottom through groove on the outer side of the casing 301, completing the rotation feeding and conveying work of the seeding groove wheel 308 on the seeds.

[0034] All of the above components are mounted, connected, or configured using conventional mechanical methods, such as welding, threading, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that achieves a beneficial effect may be employed. The aforementioned motor 303 is a commonly available commercial component. Upon purchase, it requires only connection according to the included instruction manual, so further description is omitted here.
