Description

Two formula of clamp can replace girdling sword of tool bit

Technical Field

The utility model relates to a girdling knife with a replaceable knife head in a double-clip type, belonging to the field of machinery.

Background

Jujube trees generally need to be peeled, so that the yield of the jujube can be increased and the quality of the jujube can be improved. Girdling is a work with strong technical performance, high difficulty and low efficiency, the girdling season is 5-10 days, the time is short, most jujube trees are girdled when the jujube trees bloom each year in northern China every year, the traditional girdling of the jujube trees is to cut a cut by winding a sickle around the bark of the jujube trees, an iron wire is placed in the cut and is bound at the cut by the iron wire, after a period of time, the traditional girdling of the jujube trees is to rotate and bind the iron wire on a rod or a branch by hands to prevent the healing of phloem, which wastes time and labor, has poor effect, is easy to damage the xylem of the fruit trees to cause the death of the fruit trees, in order to improve girdling technology and improve efficiency and quality, a series of girdling tools such as a hook cutter, girdling pliers, a handheld saw and the like are continuously generated in the last ten years, because the stress is uneven, the cutter head causes inconsistent girdling cut, the girdling is too wide, even the bark is torn, the girdling opening is not conform to the girdling requirement, not only do not reach the increase production purpose, still influence jujube tree normal growth, cause jujube tree death, current girdling instrument tool bit all uses two to four fix with screws at least, difficult replacement, the girdling bark in-process is very serious to cutting tool wearing and tearing, it continues to use and decreases the cutter and carry out the girdling and influence the girdling quality to grind, difficult girdling bark, the increase of girdling resistance reduces the efficiency of girdling, bad girdling makes the fruit tree death even, bad girdling causes serious consequence: 1. the balance relation between the tree crowns and the root systems is thoroughly destroyed, although the fruit setting rate can be transiently improved, if the balance relation is destroyed for a long time, the physiological function of the whole tree body is inevitably disordered, and the jujube tree is damaged; 2. the yellow leaf period can not be relieved for a long time, if the once girdling effect of the girdling device is poor, if the girdling is too narrow and the depth is not enough, the second girdling is carried out, so that the nutrition conversion period can not be smoothly carried out, the root system can stop growing because the nutrition can not be obtained for a long time, the capability of absorbing nutrient elements is lost, the yellow leaf period lasts for several months, and small yellow leaves can still appear after sprouting in the next year in serious cases; 3. the resistance of the girdling jujube trees is reduced continuously for several years, the jujube diseases are serious, the leaves of the jujube trees are small and yellow, the leaves are thinned and curled, more than 30 percent of the jujube trees only bloom and do not bear fruits, and the jujube trees are grown for years.
