Description

Jujun grasses feed mechanism for seed is with reseeding device
Technical field
The present invention relates to planting huge fungous grass field of mechanical technique, more particularly to a kind of Jujun grasses feed mechanism for seed is with reseeding device.
Background technology
Jujun grasses are a kind of huge energy grass for being planted in the non-farmland clivia ground such as poor soil, salt-soda soil, nonirrigated farmland, sand ground, resistance to Barren, drought-enduring, Salt And Alkali Tolerance, strong adaptability, growth are fast, and yield is high, and Jujun grasses have multiple use, is used not only for edible mushroom , also there is significant role in the field such as compost, bioenergy fuel, papermaking and industrial fiber raw material, feed to water and soil conservation.
However, using artificial growth the plantation of China's Jujun grasses, plantation efficiency is low more, and labour intensity is big, and economic benefit is low, Therefore, the mechanization of Juncao plantation just increasingly seems necessary and urgent.Current China plants standby development input to fungous grass Less, production unit overall strength is not strong, and product quality is not high, and bad adaptability, mechanization degree is low, and production efficiency is not high.Though The fungous grass implanting of right import is standby all to obtain preferable effect, but its fancy price in performance and quality, is also difficult to it It is widely popularized in China's Mainland.
Existing Jujun grasses feed mechanism for seed is equipped with Jujun grasses seedling storage kind case, conveying seedling device and discharge device, huge Juncao seedling is stored in kind of case, is conveyed through conveying seedling device, and through the discharging opening discharge of discharge device, once in planting case Jujun grasses seedling does not replenish in time, then need shutdown to be replenished, or feed mechanism for seed does not have Jujun grasses seedling to discharge, and influences huge The operating efficiency of Juncao feed mechanism for seed.
The content of the invention
The technical problems to be solved by the invention are:A kind of Jujun grasses feed mechanism for seed is provided with device is reseeded, as feed mechanism for seed Second Jujun grasses seedling dispenser, in the case of there is no Jujun grasses seedling in the kind case of Jujun grasses feed mechanism for seed, can and When supply feed mechanism for seed, make seeding continuity good.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:
A kind of Jujun grasses feed mechanism for seed is with reseeding device, including reseeds roller and reseed motor, on the excircle for reseeding roller At least one kinds of bank deposits groove is laid with, described reseeding reseeds roller rotation described in motor drive.
The beneficial effects of the present invention are:Reseed motor rotation drive and reseed roller rotation, it is cylinder to reseed the profile of roller, The outer circumferential sides wall for reseeding roller is provided with least one kinds of bank deposits groove, and a Jujun grasses seedling can be placed in a kinds of bank deposits groove, When kinds of bank deposits groove turns to certain position, Jujun grasses seedling falls down under self gravitation effect, from kinds of bank deposits groove, reseeds motor With reseed second dispenser of the roller as feed mechanism for seed, feed mechanism for seed is provided with first dispenser, normal as feed mechanism for seed Main dispenser during work, operation is opened when first dispenser short supply needs to replenish, and prevents feed mechanism for seed first There is interrupted seeding or shuts down the phenomenon that replenishes in individual dispenser, and allows the continuous seeding of feed mechanism for seed.
