Movable bin single-seed precision hill seeder

Abstract

The invention relates to a movable bin single-seed precision hill seeder and belongs to the technical field of a movable bin hill seeder. A plurality of seed falling ports (23) are uniformly distributed on the outer periphery of a roller (2). The roller (2) and an end cover (16) are buckled into one whole body and are arranged on a plate shaft (10) through a bearing (9). One end face of the roller (2) is provided with a switching device for a nozzle (1). A plurality of seed supplementing spoons (17) are uniformly distributed on the inner wall of the end cover (16) in a ring-shaped shape. A discharge plate (3) is arranged in the roller (2). A seed plate (4) is buckled inside the discharge plate (3). A cavity between the discharge plate (3) and the seed plate (4) is a seed charging bin (11). A cavity between the discharge plate (3) and the end cover (16) is a seed storage bin (14). The end face of the discharge plate (3), which is close to the seed storage bin (14), is provided with a seed inlet (21) and a seed overflowing port (19). A seed charging mechanism (18) is arranged in the seed charging bin (11). The movable bin single-seed precision hill seeder has the advantages of functions of automatically feeding, overflowing and cleaning seeds, accurate seeding capacity, no cavity, strong practicality and the like.

[0002] Commonly used seeders in production basically adopt drill sowing, and most of the seed metering devices are external. Commonly used seed metering devices are composed of two types, one is mechanical, such as the Chinese patent application number 200520133871.7, including adjustable groove size Outer trough wheel type seed metering device, pocket hole type seed metering device with adjustable socket size, this type of mechanical seed metering device is characterized by trapezoidal seed box placed above the seed metering device, the seed box needs to keep a certain amount of seeds, and the seeds Squeeze each other in the seed box. Due to the large friction angle of the corn seeds, the seeds around the seed meter cannot be turned, forming a vacuum area, and the seeds cannot enter the sockets and grooves, resulting in cavities. Even if seeds enter the sockets and Grooves, but because the state of seeds entering the sockets and grooves is different, when using a fixed brush or a rotating brush wheel to clean the excess seeds on the outer surface of the socket or groove, the brush wheel will be away from the socket or groove. The distance has a direct impact on the clearing of the seeds. The distance is too short to remove the seeds in the socket and cause holes. If the distance is too far, the seed cleaning effect will not be achieved. Deformation will cause the seeds to break and many seeds to fall. In addition, the flexibility of the brush or brush wheel also has strict requirements. If it is too soft and easy to deform, it will not be able to clear the seeds. If it is too hard, it will rub against the surface of the seeds when clearing the seeds. cause seed damage

[0003] The second is to improve the mechanical type, such as the Chinese patent application number 200420038217.3, which includes a spoon-type seed metering device, no brush or brush wheel to clear the seeds, so as to avoid direct damage to the seeds due to the clearing of the seeds, but both seed metering devices are Vertical (that is, placed vertically), the seed drop area is above the vertical position, the machine cannot be in an ideal state when working in the field, vibration and tilt are inevitable, the seed bounce of the spoon type seed meter will cause holes, and the finger clip type seed metering The device mainly relies on the clamping action of the spring to push the seeds forward. Due to the difference in the size and shape of the seeds, the clamping position is not fixed. During the process of pushing the seeds, the seeds are likely to fall off. It requires good spring elasticity and high processing precision.

[0005] The common feature of these types of seed metering devices is that the seeds discharged from the seed metering device are sent into the soil inserter through the conduit. It takes a certain time for the seeds to pass through the conduit, and the seeds collide with the conduit wall in the conduit, resulting in the distribution of seeds per unit time. Inhomogeneous; in addition, the seed metering device adopts the drill method of sowing, which is easily affected by the texture and water content. When the soil viscosity is high or the water content is high, the soil inserter is easy to block the soil or block it, resulting in holes and lack of seedlings. The phenomenon of monopolized ridges seriously affects the quality of sowing. During field operations, it is necessary to check the condition of the soil inserter at regular intervals, find out the problem and then solve it
