Recently, a new type of grape deep-fertilization special machinery was tested in the grape fields of Mishui Street in Gaomi City. According to the test results, the mechanical properties reached various indexes. This kind of machinery can be put into production next year.
Gaomi City has been practicing the habit of growing grapes for many years. It is very difficult for the growers to fertilize the grapes. The local farmers have been using the plough-type ditching method. The labor intensity is high, the labor efficiency is low, the labor cost is high, and the fertilization method is easy to cause the grapes. The roots are not drought-tolerant and cold-tolerant, which affects the absorption of minerals by the roots and directly affects the quality and yield of the grapes. To this end, Gaomi City Agricultural Machinery Bureau took the lead in organizing local agricultural machinery manufacturers to develop a special machine for deep fertilization of grapes. Finally, a grape vibrating deep pine fertilizing machine was successfully developed.
According to the technicians, the operation of the machine is convenient, safe and reliable, and the fertilizer utilization rate is reduced. The labor intensity is suitable for fertilization operations of various economic crops. The machine can be adjusted to a depth of up to 50 cm by using a chisel-shaped trenching and fertilizing compounding device. Auger-type fertilizer is used to force fertilizer to reduce the energy consumption of chemical fertilizers and commercial organic fertilizers into the roots of crops. The vibration is deep and the fertilization is adjustable at the same time. The machine fertilization depth (double row) 20-35 cm (single line) 35-50 cm fertiliser row spacing 70-120 cm working speed 1.5-3 km / hour production efficiency 3-6 acres / hour (single line operation) 6-12 Mu / hour (double line operation).
The screw driver is a common tool used to turn the screw to make it in place. It usually has a thin wedge head, which can be inserted into the slot or notch of the screw head.
There are mainly one character (minus sign) and cross (plus sign). There are also common hexagon screw drivers, including two kinds of hexagon and hexagon. Each screw driver has different specifications and can be customized.
According to different head types, screwdrivers can be divided into one character, cross, meter character, star (computer), square head, hexagon head, Y-shaped head and so on. One character and cross are the most commonly used in our life, such as installation and maintenance. It can be said that as long as there are screws, screwdrivers will be used.
Hexagonal head is not used much, commonly used in the hexagonal wrench, such as some machines a lot of screws are with hexagonal hole, convenient for multi angle force. We don't see many big ones. Small ones are often used to repair mobile phones, hard disks, notebooks and so on. We call small screwdrivers clock batch. We often use star T6, T8, cross pH0, ph00 and so on.
