Inventing knives, cutting and peeling machines

Thanks to the invention of a bamboo splitting knife and a peeling machine, it is used to make rice cakes (often called easy), Bui Van Du in Bac Giang earns hundreds of millions of dong each year from developing the easy weaving and solving career. jobs for dozens of local workers.

A set of bamboo splitting knives invented by Mr. Bui Van Du.

Mr. Du (born in 1970, in Hiep Dong village, Thuong Thang commune, Hiep Hoa district) said that in the early 90s, due to his poor life, he and some of his friends in the village often had to ride to the region. the mountains of Bac Giang and Thai Nguyen provinces to cut the bamboos into chopped into a piece of bamboo for sale.

In 2001, during the visits to Chiem Hoa (Tuyen Quang province) to exploit cork, he found the relatives here had a machine to remove nanoparticles. Since then, he had the idea to make the knife and nan peeling nan peeling machine to help the cork, knit and be quick and hard work.

In early 2005, Mr. Du began to explore, experimenting on how to make knives and splitting machines, and peeling nan. After several months, in July 2005, he successfully built a machine to make a bamboo stick and a set of splitting knives. The set of bamboo splitting knives made by him consists of a 50cm long blade, 5cm wide, cut into 10 sections, welded together in a "circular diameter" bunched at the center. The outer end is welded to an "improved wheel" iron ring, on the outside of the iron rim, two pieces of symmetrical iron pipe are used as handles.

The set of knives is designed with different sizes of knives to suit different types of cork. When used, the splitting knife splits one time with 10 spokes from one section, each one is the same, while the former has to be split into 10 to complete. The price to make a set of slitting knives is only about VND 800,000.

The machine stripped nan is made by Mr. Du with a V4 iron frame; 4 feet 40cm high; 2 floor frames area about 40cm x 40cm. The floor frame is 10cm below the ground to mount the electric motor; The upper floor frame is the frame to mount the bamboo peeling machine. The body consists of 8 parts which are the transmission shaft; roller parts; thick, thin, fast, slow adjustment box section; machine screws fixed; the blade is split; garbage troughs; troughs placed nan; electric motor.

His creative point: When making this machine, it has changed 3 screws to keep the body fixed by spring screws, so the machine has automatically opened for the cork to pass, when it is over, it automatically presses. come back, forming an automated open process, pressed in the process of stripping nan. The cost of making a peeling machine is only about 2 million dong.

In terms of economic benefits, with 1 set of bamboo splitting knives and 1 slotting machine, 1 worker per day will reach the same number of products as 80 manual workers in 1 day ago; provide enough jobs (easy knitting) for 20 employees. With an easy labor of about 2,500 VND / piece, an average worker can earn 20 VND / day and earn 50,000 VND; A skilled knit worker of 25 or more will earn an income of 75,000 VND or more per day.

Currently, Mr. Du's family is employing about 20 workers working as a knitting worker. In 2011, his family sold about 120,000 to easily supply to multi-village villages, noodles, vermicelli, rice cakes . in Van Ha, Chu (Luc Ngan district, Bac Giang) and in some Other provinces and cities such as Bac Ninh, Thai Nguyen, Dac Nong, Ho Chi Minh City.

Except for the cost, in the past year, Mr. Tien's family made about 250 million VND, each employee earns about 2 million VND / person / month. From 2005 up to now, Mr. Du has produced and supplied 15 bamboo peeling machines to people in Hiep Dong village. The whole village now has about 320 laborers involved in making splits, peeling and weaving, and the average income is from 1.5-2 million VND / person / month. Every year the village has sold nearly 650,000 easy, collected billions of dong.

Mr. Bui Van Du's invention of a knife and fork knife has won the first prize at the Bac Giang Farmers' Technical Innovation Contest for the fourth time in 2011 and was awarded the second prize at the Creative Competition Technique of Bac Giang province for the fourth time in 2011.
