Description

Potato seed production device

Technical Field

The utility model belongs to the technical field of agricultural machine, concretely relates to potato seed production device.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Potato is an important grain crop next to rice, corn and wheat, and for potato which is a vegetative root crop, root tuber seeding is adopted. The roots of the asexually propagated root crops are cut into pieces to obtain root tubers within a preset weight range. The quality of the whole seed potato to be diced is controlled to be between 50 and 160g, and the seed potato is not diced when the weight of the seed potato to be diced is less than 50 g. When 50-160g of whole seed potatoes are cut into blocks, the quality of the blocks is generally controlled between 25 g and 30 g, and at least one bud must be left on each block. Therefore, potato seeds with different sizes are symmetrically and longitudinally cut along the long axis and then are cut into blocks in different modes, wherein 50g of single-petal potato seeds are not cut into blocks, 51-75 g of single-petal potato seeds are longitudinally cut into two petals, and 75g of single-petal potato seeds are longitudinally cut into two petals and then three petals. After the cutting, the seed potatoes need to be disinfected by using solid or liquid such as plant ash and the like in combination with solid chemical agents so as to ensure good growth rate and prevent root rot.

At present, seed potatoes are basically cut into blocks by manpower, the automation degree is very low, the efficiency is low, and the seed potatoes are easily restricted by subjective factors. In the dicing process, cutters in different shapes are selected according to the size of the root tuber obtained according to the requirement, and then matched cutters are sequentially selected from large to small to obtain the root tuber with the size finally required, for example: the cutter comprises 51-70 g of a common one-shaped cutter and 71-100 g of a common Y-shaped cutter. The dicing is carried out on the root of the block, various streamline cutters need to be prepared, the dicing process is complicated, and the dicing efficiency is reduced. And the dicing device is mostly blind cutting, the number of the bud eyes on the seed potato tuberous roots is not noticed, the number deviation of the bud eyes of the obtained seed potato tuberous roots is too large, the volume size is different, the nutrient supply in the growth process of the dices is difficult to ensure, the resource waste of the seed potatoes is easy to cause, the dicing quality is reduced, and the high yield of the tuberous root crops is difficult to ensure.

The inventors have appreciated that the current industry is dominated by mechanical dicing, where potatoes are placed in a seed cutting machine which automatically cuts the potatoes as desired. At present, the potato seed cutting machines on the market can be divided into two categories: intelligent control type and spoon and knife fixing type. The existing machines are generally poor in universality and easy to miss. Because the potato block weight control and the bud eye recognition capability are limited, the potato block size adaptive capability and the bud eye recognition and cutting capability are not ideal enough.

Zhao Xuanming, etc. invents a potato seed cutting machine. The design realizes mechanical dicing to a certain extent, but the weight of the potato blocks cannot be controlled, and the number and the positions of the eyes of the potato blocks cannot be determined no matter the size of the seed potatoes, but only the eyes of the potato blocks are ensured.

Guo Shidong et al invented an automatic seed cutting machine for potato. This design has realized intelligent mechanized stripping and slicing to a certain extent, has controlled the weight of potato piece, but no matter kind potato size, can only cut into two, obviously can not satisfy the actual demand of sowing, and this kind of seed cutting machine also does not have eye of the bud recognition function simultaneously.

The Liuwen tomahawk et al invented a multistage self-align screening and intelligent seed production device of bud eye discernment, overcome equipment blind cut, realized the flexible self-align of seed potato, but the device does not have the screening function, and machine discernment dicing part can't judge the lower sword through seed potato volume weight in addition, does not have cutter disinfection function in addition.

In conclusion, the existing potato slicing machine has the problems of potato block quality control and slicing, but also has the defects of low universality, incapability of multi-stage screening, limiting and slicing and bud eye identification seed production.
