Abstract
The positive and negative pressure air suction type roller precision seeding apparatus. The invention has simple structure, easy operation and high seeding efficiency. The device mainly comprises a roller air suction and collection module, a wind power conveying module, a transmission module, a vibration module and a rack module. The roller air suction collecting and discharging module mainly comprises a roller, a shell, a brush, a hollow shaft, a positive pressure area and a negative pressure area. The invention is characterized in that: the mechanical force drives the roller to rotate through the driven chain wheel; the fan is connected with a hollow shaft fixed on the frame through an air supply pipe to form a negative pressure area in the roller; the vibrating block and the spring arranged on the seed box work during seed filling so as to improve the seed filling performance of seeds, the friction force generated by rotation of the roller and the suction force provided by the negative pressure area rotate along with the roller during seed carrying, and when the seeds are transferred to the brush, redundant seeds are removed without damage, so that the reseeding rate is reduced. The positive pressure area is arranged under the roller, the opening is communicated with the atmospheric pressure, the positive pressure area is formed, the seed is conveniently discharged, when the positive pressure area is rotated, the negative pressure disappears, and the seeds fall into the seed outlet below the roller by the gravity of the seeds to realize seed throwing.
Description
Technical Field
The invention discloses a positive and negative pressure air suction type roller precision seed sowing device, and relates to the technical field of agricultural machinery.
Background
With the rapid development of modern agricultural technology, the development of precise agricultural technology towards high speed and precision is promoted. During sowing operation, the precision high-speed sowing can reduce the great waste of seeds, reduce the production cost, rob the farming season, improve the sowing efficiency, have obvious promotion effect on realizing yield increase and stable yield and have certain economic benefit; but also has certain defects: different sizes of seeds are often considered when the roller is designed, so that a plurality of staggered and different adsorption holes are required to be drilled, the pressure in the negative pressure chamber is reduced, sufficient adsorption force cannot be provided, a larger fan is often required, the pressure of different parts in the negative pressure chamber is different, and the phenomena of rebroadcasting missing and the like are easily caused; most seed metering wares are the integral type nowadays, thereby can influence the circumstances such as high-speed kind and seeding because different vibrations appear in different field operating mode.
Disclosure of Invention
In view of the above problems, the present invention provides a positive and negative pressure suction type roller precision seed sowing device to solve the problem of unstable seed sowing of the existing suction type seed sowing device.
The scheme adopted by the invention for solving the problems is as follows: the positive and negative air-compression suction type roller precision seed sowing device consists of a roller air-suction collection and discharge module, a wind power conveying module, a transmission module, a vibration module and a rack module.
For the positive and negative pressure air suction type roller precision seed sowing device, a negative pressure shaft 7 is connected with a fan 12 through a ventilation pipe 11 to provide negative pressure for a negative pressure area, a roller 1 provides power for rotation through a driven chain wheel 3, a vibration block 8 vibrates a seed box, so that seeds in the seed box can be more stably adsorbed on the roller by negative pressure provided by a negative pressure cavity to rotate along with the roller, when the seeds reach a brush 10, redundant seeds can be brushed off and not damaged, when the seeds reach the positive pressure cavity, the adsorption force disappears, and the seeds fall into a seed sowing hole by self gravity to realize stable seed sowing.
It is right positive and negative pressure air suction type roller precision seed metering ware, brush simple structure adopts special material to the injury of seed when reducing the brush kind, and vibrating mass and spring cooperation vibrate seed case and in order to improve the seed filling performance of seed, and two rows of adsorption holes of not uniform size of cylinder stagger are in order to satisfy the seed of different grade type.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, a roller 1 is arranged in a shell 2, a certain gap is reserved between the roller and the shell, a hollow shaft 7 is fixed on a rack 5 through nuts, the shells on two sides and the roller 1 form a negative pressure area 6, a positive pressure area 4 is connected with the outside through a seed sowing hole, and a vibration module 8 is arranged on a seed box 9.
As shown in figure 2, a fan 12 is connected with a hollow shaft 7 fixed on the frame through a gas pipe 11 to provide negative pressure, a brush 10 is arranged on the shell to reduce the reseeding rate by brushing off redundant seeds without damage, and a seeding hole is arranged right below the shell 2, so that the seeds can be discharged by gravity when entering a positive pressure area.
As shown in fig. 3, the vibrating block 8 vibrates to make the seed box sway left and right, and the seed box extrusion spring rocks left and right to improve the seed filling performance of the seeds.
As shown in fig. 4, the roller has two rows of suction holes staggered to suck the seeds of different sizes.
As shown in figure 5, the brush has simple structure, adopts special flexible materials, does not hurt the seeds, and greatly reduces the reseeding rate.
As shown in fig. 6, a total of 20 holes are formed in the hollow shaft, and the holes in each group of 4 holes form an included angle of 90 degrees.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention is innovative with reference to the preferred embodiments and should not be considered as excluding other embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the inventive solutions, which should be covered by the claims of the present invention.
