Chain-drum type precise dibbling machine

Abstract

The invention provides a chain-drum type precise dibbling machine which comprises a seed bin, a chain drum, a seed supplementing spoon and a transmission wheel, wherein the seed bin is arranged above a stand; the outer side surface of the seed bin is fixedly connected with the stand by a longitudinal side plate; the angle formed by the seed bin and the horizontal plane of the stand is 40-45 degrees; the two ends of the bottom surface of the seed bin are respectively provided with a rectangular through hole; the chain drum is connected on a chain wheel in a hanging way; the chain drum passes through seeds on the inner surface of the bottom surface of the seed bin; the seed supplementing spoon is arranged on a seed supplementing wheel shaft and is driven to rotate by a driving chain wheel; the rotating direction of the seed supplementing spoon is the same as that of the chain drum; the seeds are taken into the seed supplementing spoon, the seed supplementing spoon is driven to rotate by the chain wheel, seeds in the spoon are continuously poured into the chain drum, the chain drum is guaranteed to be fully filled with the seeds, the chain drum is driven to rotate by the chain wheel, a certain included angle is formed between the chain drum and the horizontal plane of the stand, the seeds on the outer surface of the chain drum falls back into the seed bin under the action of gravity, the chain drum continuously rotates, and the seeds fall into a sowing pipe, so that the precise dibbling can be realized.

Description

technical field [0001] The invention provides a chain cylinder type precision hole seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] Commonly used seed metering devices in production are composed of two categories, one is mechanical type, including the outer groove wheel type seed metering device with adjustable groove size, and the pocket hole type seed metering device with adjustable hole size. The characteristic of the seed device is that the trapezoidal seed box is placed above the seed meter. The seeds in the seed box need to be kept in a certain amount. The seeds squeeze each other and cannot be turned, forming a seed-filled vacuum area, and the seeds cannot enter the sockets and grooves, resulting in cavities; even if there are seeds entering the sockets and grooves, the states of the seeds entering the sockets and grooves are different. , when using a fixed brush or rotating brush wheel to clean the excess seeds on...

AI Technical Summary

Problems solved by technology

The common feature of these two 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 ridge breaking seriously affects the quality of sowing. During field operations, it is necessary to check the condition of the soil inserter at a certain interval, and solve the problem in time if the problem is found. None of the seed meters can meet the sowing requirements
