Description

A vibrating shovel ginger digging and ginger three-stage sieving soil cleaning mechanism

technical field

The invention relates to a vibrating shovel ginger digging and ginger three-stage soil sieving mechanism.

Background technique

The ginger harvesting process includes three parts: the harvesting of ginger pieces, the harvesting of straw and the rotary tillage of ginger fields. This organization is mainly involved in the excavation of ginger and the sieving and cleaning of ginger. At present, ginger is harvested by manual planing and mechanical harvesting. Manual harvesting is easy to damage the ginger, which takes a long time and is very inefficient. The soil removal and cleaning work is also mainly done manually, which is extremely time-consuming and laborious. Mechanical harvesting has greatly improved harvesting efficiency and reduced people's labor, but at present, mechanical harvesting still requires manual participation, and has not really liberated manpower. Prolonged harvesting time, increased harvesting cost.

my country is the largest ginger planting country in the world. As the demand for ginger continues to increase in the market, the larger the planting area in my country, the greater the output of ginger. Manual harvesting cannot satisfy the status quo, so the mechanization of ginger harvesting is the future development trend. The following are the more advanced ginger digging and cleaning machines at home and abroad.

In 1991, Japanese Fujiki and Hongxi applied for the patent of ginger harvester. The working principle of ginger excavation is that the ginger harvester advances along the ginger planting line, the crop divider first guides the ginger stalks into the reel, and then the reel feeds the ginger stalks into the clamping belt. The movement and the advancement of the machine, the clamping belt pulls out the ginger stem from the ground, thereby completing the excavation of the ginger. However, after the ginger is taken out, it still needs to be manually picked up, further cut, cleaned, and boxed.

In 2002, the agricultural machinery department of Laiwu City, Shandong Province developed the 4JS-1 ginger harvester matched with the walking tractor, and the patent application number is 02270279.2. The working principle of the ginger digging machine is that after the straw and ginger are cut and separated with a cutter, the underground ginger rhizome is loosely dug by a ring-shaped deep loosening plow, and the ginger block is moved out of the soil as a whole without being turned over, ensuring the integrity of the ginger block sex. However, the follow-up work is to manually dig out the ginger from the soil. The machine only saves a little effort of manual digging, and does not complete the excavation of ginger.

In 2005, the Shandong Agricultural Machinery Science Research Institute developed the 4GJ-1 ginger harvester, and the patent application number is 200520083134.0. The working principle of the ginger digging machine is that the ginger harvester advances along the ginger planting line, the crop divider first guides the ginger stalks into the reel, and then the reel feeds the ginger stalks into the clamping belt. The movement and the advance of the machine pull the ginger seedlings and ginger pieces out of the ground together. This machine uses a clamping device to pull out the ginger from the soil, which is easy to damage the ginger. Moreover, no follow-up work was carried out.

In 2006, Luo Hongming, Huangniwa Town, Liaoyang County, Liaoning Province invented the wheel-fork ginger harvester, and the patent application number is 200620093152.1. The working principle of the ginger digging machine is that the ginger harvester is pulled by a small tractor or a walk-behind tractor, the wheel fork is first inserted into the soil to loosen the soil, and the ginger stem is lifted up, and the ginger is lifted by hand. The soil surface is raised, and then the ginger seedlings are cut short with scissors, thereby completing the ginger harvest. This machine still continues the working principles of the above machines, and does not fundamentally liberate manpower.

In February 2014, Nanjing Gray Agricultural Equipment Co., Ltd. invented a digging shovel with the function of dividing soil. The patent application number is 201420225270.8. The soil clods can be used for harvesting machinery of rhizome plants such as potatoes, peanuts, garlic, ginger, etc., to reduce the soil content of the rhizomes when they are unearthed. But its singularity determines that it cannot liberate labor in a wider field.

However, there are some ginger cleaning machines on the market, such as a ginger cleaning machine developed by Sichuan Wudoumi Food Development Co., Ltd., the patent application number is 201320753091.7, which includes a feeding frame, a material frame, and a mixing bucket. Transmission device, the rotating drum arranged on the right side of the transmission device, the right end of the transmission device extends into the inside of the rotating drum, the material frame is arranged below the outlet of the rotating drum, and the mixing bucket, the transmission device and the frame where the rotating drum are located are all provided with Motor; the feeding frame is connected with the lifting device arranged on the frame where the mixing bucket is located, and the lifting device and the mixing bucket are connected with the motor on the frame where the mixing bucket is located; a spraying device is arranged on the rotating drum, and the rotation Several water outlet holes are arranged inside the drum.

A ginger cleaning machine from Fujian Haori Food Co., Ltd., the patent application number is 201320255405.0, which has a conveyor belt with a stainless steel mesh belt; several upper spray pipes are arranged above the upper section of the conveyor belt, and each upper spray There are several upper nozzles on the water pipe, and the upper nozzles are all facing the upper surface of the upper section of the conveyor belt. The angle between each upper nozzle and the upper spray pipe is between 20 degrees and 90 degrees; There are several lower spray pipes, and each lower spray pipe is provided with several lower nozzles, and the lower nozzles are all facing the lower surface of the upper section of the conveyor belt, and the angle between each lower nozzle and the lower spray pipe is 20 degrees to 90 degrees Between; the upper water spray pipe and the lower water spray pipe are connected with the water pump.

The main work and principle of these ginger cleaning machines is to use water and brushes to clean the ginger. However, the ginger put in must be separated from the large clods, that is, the ginger after manual processing is cleaned. , and there is no ginger cleaning mechanism combined with the ginger digging mechanism.

However, the existing ginger excavation mechanisms on the market only dig out the ginger and soil clods together, and the follow-up soil removal and cleaning process still needs to be solved manually.

The above machines simply complete the removal of ginger stalks and the loosening or excavation of ginger pieces, but the problem of machine cleaning of ginger pieces is not completed. Still need a large amount of manpower input in the ginger harvesting process, did not liberate the labor force.
