Abstract
The utility model provides an adjustable vegetable seed-metering device which can solve the problem that the traditional mechanical seed-metering device is difficult to control the seeding particle size on the premise of meeting the precision seeding. The novel adjustable vegetable seed sowing device comprises a shell, a seed protecting plate, a lead screw, a fixed seed sowing plate and a movable seed sowing plate. The screw rod is rotated to drive the movable seed metering disc to move axially, so as to adjust the aperture size and achieve the purpose of controlling the particle size.
Description
Technical Field
The utility model relates to an adjustable vegetable seed sowing device, which is used for precision sowing of vegetable seeds and belongs to the field of agricultural machinery research.
Background
With the continuous development of economy, agricultural production structures in China are also changing greatly, agricultural planting advances from a single grain type to a multiple economic type, vegetable planting is used as an important field of agricultural planting, in recent years, the vegetable industry develops rapidly, the planting area rises continuously, and the vegetable industry exceeds grain at present, becomes the first big agricultural product industry in China, and is one of the pillars for agricultural economic development. However, the vegetable seeds have different shapes due to small particle size. At present, the sowing mode of vegetable seeds is relatively lagged behind, manual and semi-mechanical operation is mainly used, and the defects of low efficiency, large using amount, high cost and the like exist. The mechanical degree of the seeder is low, and for the seeder, the core part is a seed sowing device, but the existing seeder seed sowing device generally adopts an external fluted-wheel constant seed sowing device, has high seed damage rate and poor uniformity, can only realize the precision seeding of large and medium seeds, and can not implement the precision seeding of small seeds, therefore, the structure of the seeder seed sowing device is improved, and the improvement of the planting efficiency is imperative.
Disclosure of Invention
Aiming at the problems that the seeding quality is low (plant spacing, heavy planting and seed leakage) and the aperture of the traditional mechanical seed sowing device cannot be adjusted in the vegetable seed sowing device in China, the adjustable vegetable seed sowing device with adjustable seeding particle size is designed, and the standardized precision seeding of different vegetable seeds is realized.
In order to achieve the purpose, the utility model is realized by adopting the following technical scheme.
An adjustable vegetable seeding device comprises a screw rod (1), a movable seeding disc (2), a brush (3), a shell (4), a fixed seeding disc (5) and a transmission shaft (6). The movable seed metering disc (2) is connected with the screw rod (1) through a bearing, the screw rod (1) is screwed in a spiral hole of the shell (4), and the screw rod (1) is rotated to move axially, so that the movable seed metering disc (2) is driven to move axially, and the purpose of controlling the aperture is achieved.
Furthermore, a key groove is formed in an extending shaft on the inner side of the fixed seed metering disc (5), the center of the movable seed metering disc (2) penetrates through the extending shaft on the inner side of the fixed seed metering disc (5) to be fixedly connected with the fixed seed metering disc (5) through a key, the key groove is also formed in a sleeve extending out of the outer side of the fixed seed metering disc (5) to be fixedly connected with the transmission shaft (6) through a key, when the transmission shaft (6) rotates, the fixed seed metering disc (5) is driven to rotate, and the fixed seed metering disc (5) drives the movable seed metering disc (2) to rotate.
In summary, compared with the prior art, the utility model has the advantages and positive effects that:
the vegetable seed sowing device with the adjustable grain diameter is developed, so that the vegetables of different types can be sowed in a precise manner by only using one machine, the planting cost of farmers is reduced, and the sowing efficiency is improved.

Detailed Description
Example 1
As shown in fig. 1-4, in the embodiment of the utility model, an adjustable vegetable seeding apparatus comprises a screw rod (1), a movable seeding disc (2), a brush (3), a shell (4), a fixed seeding disc (5) and a transmission shaft (6); the working principle is as follows: the fixed seed metering device 5 is externally connected with a transmission shaft (6) by a key, a key groove is formed on an external extension shaft at the inner side of the fixed seed metering device, and the fixed seed metering disc 5 is connected with a movable seed metering disc (2) by a key; the transmission shaft (6) rotates to drive the fixed seed metering disc (5) and the movable seed metering disc (2) to synchronously rotate;
example 2
Aiming at the particle sizes of different vegetable seeds, the screw rod (1) can be rotated to enable the screw rod (1) to move in the axial direction, one end of the screw rod (1) is connected with the movable seed metering disc (2) through a bearing, so that the movable seed metering disc (2) is driven to move in the axial direction, the distance between the movable seed metering disc (2) and the fixed rotary disc is changed, and the purpose of adjusting the aperture is achieved.
