Abstract
The utility model relates to a double-cavity intermediate-transmission air-suction type seed sowing device. The double-cavity seed sowing device of the current air-suction type precision seeder has two transmission forms of a middle bevel gear transmission type and a sprocket wheel and cantilever side transmission type; the structure is simpler, the manufacturing cost is relatively lower, and the installation is easy; and however, because a shaft of the seed sowing device needs to pass through a seed loading chamber at one side, the length is increased, the overlength of a cantilever causes poor stress, and a seed loading chamber with a sprocket wheel transmission side is not easy to open, which causes difficult plate replacement and maintenance at the side and complicated disassembly and assembly. The double-cavity intermediate-transmission air-suction type seed sowing device comprises a casing (7) of the air-suction type seed sowing device, wherein two seed sowing cavities (8) are arranged in the casing of the seed sowing device, planter plates (6) are arranged in the seed sowing cavities, a seed sowing shaft (5) is connected with the two planter plates, and sprocket wheels or gears (3) are arranged on the seed sowing shaft. The utility model is used for agricultural air-suction type sowing.
Description
Technical field:
The utility model relates to two-chamber intermediate chain wheel transmission air-suction seeding unit in a kind of agricultural machinery.
Background technology
The two-chamber seeding unit of current air-suction type accurate sower has 2 kinds of type of belt drive: a kind of is the Intermediate bevel gears driven type, this kind structure stress is good but make the processing cost height, the requirement on machining accuracy height is adjusted loaded down with trivial detailsly in the assembling process, adjust improper meeting and cause rotating dumb torsion and increase as installing; Another kind is exactly a sprocket wheel cantilever side driven type, this kind is relatively simple for structure, manufacturing cost is relatively low, install easily, so but because the seeding unit axle need increase by side dress kind of chamber length, cantilever is long, stressed bad, and has the dress kind chamber of chain gear transmission side to be difficult for opening, cause this side to change dish, difficult in maintenance, dismounting is loaded down with trivial details.
Summary of the invention:
The purpose of this utility model provides a kind of novel air-sucking type two-chamber seeding unit, and dish is changed in dresses kind of a chamber in both sides or putting kind etc. to open all is very easy to, and the earth has made things convenient for operations such as installation, adjustment, maintenance.
Above-mentioned purpose realizes by following technical scheme:
Transmission air-suction seeding unit in the middle of the two-chamber, its composition comprises: the air-suction seeding unit shell, have two seeding chambeies in the described seeding unit shell, and described seeding is equipped with seed plate in the chamber, feed shaft connects described 2 seed plates, and sprocket wheel or gear are housed on the described feed shaft.
Transmission air-suction seeding unit in the middle of the described two-chamber, described feed shaft is connected by bearing with driving center in the seeding unit shell, and described seed plate is installed on the driving center.
Beneficial effect:
1. the utility model adopts intermediate chain wheel or type of belt drive, and simple in structure, cost is lower, and machining accuracy is not high relatively, installation, easy to maintenance.
2. the utility model adopts intermediate chain wheel (or gear) drive mechanism, does not have cantilever, and stressed reasonable, feed shaft is stressed good, indeformable, has improved the reliability and stability of transmission performance.
3. this kind air-sucking type two-chamber row device is the advantage in conjunction with existing two class drive mechanisms, and low cost of manufacture, machining accuracy are lower than Intermediate bevel gears, because therefore the seeding unit axle can not cause broken kind at both sides dress kind of an indoor no external part.
4. the utility model adopts dress kind of chamber, both sides to open conveniently, is very easy to and changes dish and put kind of an operation.When the material of dress kind of chamber adopts polycarbonate engineering plastic, can the clearer working condition of observing seeding unit.
5. the utility model has changed the version of existing seeding unit, modern design, and practicality is better.
Description of drawings:
Accompanying drawing 1 is a structure chart of the present utility model.
Embodiment:
Embodiment 1:
Transmission air-suction seeding unit in the middle of the two-chamber, its composition comprises: air-suction seeding unit shell 7, have two seeding chambeies 8 in the described seeding unit shell, and described seeding is equipped with seed plate 6 in the chamber, feed shaft 5 connects described 2 seed plates, and sprocket wheel or gear 3 are housed on the described feed shaft.
Described sprocket wheel 3 is connected the centre position of seeding unit shell 7, the axle 5 of described seeding unit passes sprocket wheel 3, driving center 1 usefulness bearing 2 axial restraints of described feed shaft 5 and seeding unit shell 7, fixing with resilient key 4 between described sprocket wheel 3 and the feed shaft 5, described seed plate 6 is installed on the driving center 1.
Operation principle:
Chain drives driving center by feed shaft at first for transmission of power sprocket wheel or gear and drives the seed plate rotation by driving center again, thereby the circumference that reaches seed plate rotates, and realizes seeding operation.
Claims (2)
1. transmission air-suction seeding unit in the middle of the two-chamber, its composition comprises: the air-suction seeding unit shell, it is characterized in that: have two seeding chambeies in the described seeding unit shell, described seeding is equipped with seed plate in the chamber, feed shaft connects described 2 seed plates, and sprocket wheel or gear are housed on the described feed shaft.
2. transmission air-suction seeding unit in the middle of the two-chamber according to claim 1 is characterized in that: described feed shaft is connected by bearing with driving center in the seeding unit shell, and described seed plate is installed on the driving center.
