2, the main features:
After the design of product drawings was completed at the end of May 2002, Nanchang Mining Research Institute's Nanchang Mine Research Rotary Tillage Plant was put into trial production. At the end of October 2002, two prototypes had been assembled. Since August 2003, livestock husbandry in Jiangxi Province began. The field trials were conducted in industrial trials and tested by Jiangxi Agricultural Machinery Quality Testing Center. The model has the following characteristics:
1. This model is a variable-speed rotary cultivator with double functions of rotary tillage and stubble elimination, which not only increases the stubble elimination function, but also retains all the advantages of the original model rotary tillage operation. The structure of the whole machine is simple, the center of gravity is stable, all the gears rotate in the middle, the rigidity is good, the frame is firm, there is no side drive, and it is symmetrical. The weight of the whole machine is only 25kg more than the single-function model, and the added weight only occupies the total of the rotary cultivator. The weight of 6.1%, so the impact on the overall performance of the machine is small, supporting 50HP tractor is completely suitable, stable and reliable, "a machine with dual-use, you can save the purchase of agricultural investment.
2. The speed change is convenient and quick, and the rotary tillage speed is changed to the stubble speed. Only by dialing the shift lever on the transmission box, the required rotation speed can be achieved, and the rotation direction is also changed. The entire transmission system is only in the basic model: Based on the addition of two gears.
3. Extermination function: Before rotary ploughing, a shallow ploughing and hoeing is performed first, and the root pods are crushed and dispersed uniformly. When the ploughing operation is performed, the crushed root pods are buried in the shallow soil, which is favorable for accelerating rot and decomposition. Play a fertilizing role.
4. With the basic machine, type versatility is good, because the new transmission box and the original 1GQN180 rotary cultivator transmission box box center distance, the same width, the main gear, shaft, cover, couplings, hoods, trailers The board and other parts are all common, and the general rate of parts and components is more than 80%. Not only the production plant is easy to put into production on the original production line, but also the maintenance of users and the supply of accessories are very convenient.
5. Replacement of cutter shaft and tool is convenient: Due to the different rotation directions of rotary tillage and stubble, the direction of rotary tiller is changed with the change of rotation direction. This model only needs to remove the four fixed flanges at both ends of rotary blade shaft. With bolts, this can be achieved by turning the cutter shaft backwards. It is also possible to remove the machete and replace it with an unused blade.
6. Improved the sealing of the bearings at both ends of the rotary cultivator's cutter shaft. This model has absorbed the success of the 1GQD type multi-functional rotary cultivator certified by the Nanchang Institute of Mine Machinery in 2001. It has been specially designed at both ends of the cutter shaft. Sealed by shaft plus type 0 seal, the labyrinth seal pair of skeleton oil seal is lined in the hole seal, which effectively prevents invasion of external mud, water, and dust during operation, and it also extends the bearing service life and maintenance cycle. the goal of.
Based on the above characteristics, this group believes that the model is based on the advantages of various types of aircraft, based on practical applications, and developed from a simple, practical and universal basis to develop a new type of rotary cultivator. Therefore, the aircraft is predicted. Type will have better promotion value and development prospects. At present, the product has obtained the national patent, the patent number is ZL02277449.1, the patent announcement date is November 19, 2003.
Second, the industrialization prospect
1. Market Significance The results of this project are mainly used in domestic agricultural production departments, but after large-volume production, they can strive to export to Southeast Asia and other countries. The geographical conditions in Southeast Asia and other countries are close to those in South China, and many Chinese agricultural machinery products have been exported to the region.
2. Market Capacity The project's market coverage includes paddy fields and drylands throughout the country. The annual output of rotary cultivators in China reaches 200,000 units and the market capacity is very large.
3. There are more than 60 enterprises that produce rotary boring machines in the country. However, all of them are production-free rotary cultivators with a single function. There are many production companies and agricultural machinery specialists who are self-employed according to the needs of the market; many kinds of multi-purpose rotary cultivators have been developed. However, due to various reasons, no mass production has been formed: My unit has accumulated many years of development and production of rotary ploughing. The experience of the aircraft, as well as the full market research, has gone through: careful design, trial and error, and closeness to maturity, so this result has a great competitive advantage. At the beginning of the month of 2003, after we published the information on the successful trial production of the “Speed-Shifting Rotary Cultivator†in the relevant magazine, many users immediately wrote a letter calling for purchase or cooperative production, such as: Hebei Agricultural Machinery Production in Quzhou, Jinan, Shandong: Right Machine Company, Beijing's new technology promotion unit. After the identification of this project, we will immediately contact the relevant departments to put the product on the market as soon as possible.
The Diode Laser (800nm or 810 nm wavelength)
In my opinion, the Diode laser is the next most useful Hair Removal light source and the most promising laser for hair removal.
These Diode systems deliver a longer wavelength than the Ruby (694 nm wavelength) and the Alexandrite (755 nm wavelength) lasers, but a shorter wavelength than the Nd: Yag (1064 nm wavelength) laser. This longer wavelength enables the light to penetrate deeper and is theoretically safer than shorter wavelength lasers because it can better avoid the melanin pigment in the skin's epidermis. The Diode laser's longer wavelength of light thereby penetrates into the hair follicle without causing as much epidermal injury as the Ruby or the Alexandrite. This fact allows the Diode laser to be used on darker skin colors than the Ruby or Alexandrite.
Because the Diode is the most recently introduced of the hair removal lasers, there is less experience and less long-term data in evaluating the Diode's claims. Newer Diode lasers such as the SLP 1000 are attempting to deliver longer durations of light (up to 1000 milliseconds) in order to protect the epidermal pigment thereby producing fewer side effects while producing better hair removal. There is just not enough experience with these newer machines, which have only been on the market since early 2001 (after having been re-modified)! These longer durations are designed to emulate the longer durations available for five years with the UltimateTM Light treatments. Surprisingly, the pulse durations on the Quantum, Aculight, or Vasculight systems have been made shorter, while lasers try to lengthen their durations to catch up with the UltimateTM Light pulsed light.
The 800 nm Diode at this time is probably capable of treating skin types 1, 2, 3; possibly 4, 5; and maybe 6. I would personally wait for more information and experience before recommending this machine. In my opinion, the Ultimate Lightâ„¢ pulsed light is the best overall machine for treating all six skin types based on safety and long term use (over nine years). However, for effective short-term treatment of skin types 1 to 4, I believe that the 808 nm Diode is satisfactory.
