Abstract
The utility model relates to a perforator, which comprises a handle, etc. The handle is connected with the sleeve of a sliding plug, and the inside of the sleeve of the sliding plug is placed with a sliding plug. The sliding plug is connected with a push cap via a blocking key, and the other end of the sleeve of the sliding plug is connected with a needle clamp. The outside of the needle clamp is provided with the sleeve of the needle clamp, and the needle clamp is fixed with a hollow needle. The inside of the hollow needle is provided with a pricker, and the upper part of the pricker is connected with the spring of the blocking key. The outlet holes pricked by the perforator has the advantages of equal hole diameter, regular hole shape, no peripherical burrs, high precision, and uniform outlet.
Description
The utility model relates to a kind of hole making drill in infiltrating irrigation Guan Shangzha hole.
From 19th-century mid-term, just begun to utilize perforated pipe-line to carry out the experimental study of sub-irrigation abroad.The U.S. has succeeded in developing special-purpose infiltrating irrigation pipe to initial stage 1980's.After this, states such as France, Japan, Belgium, Britain, Iceland also successively to have succeeded in developing with polyolefin, waste rubber tire be the infiltrating irrigation pipe of raw material.At present, infiltrating irrigation is widely used in irrigations such as greenhouse, land for growing field crops, orchard and greening in the part country of the U.S., France, Japan, Australia and Middle East.China is introducing and is beginning one's study drip irrigation technique then, begins to build infiltrating irrigation engineering pilot in promptly 1974, and in the period of afterwards several, units such as institute of Henan water-saving section, institute of Chinese water section, Tsing-Hua University, institute of Shanxi water-saving section have all carried out great deal of experimental.But regrettably, fail to be applied.At present, in the infiltration irrigation technology that use in the whole nation, during owing to opened round hole on the thin-walled plastic pipe, all use solid pinprick hole, the hole of leaving is irregular, and dimensional discrepancy is big, and circular band burr etc., cause water outlet seriously inhomogeneous, cause easily and prick place, hole material retraction, further aggravate the deviation of the water outlet uniformity.
The purpose of this utility model be for provide a kind of apopore pore size of pricking out to equate, hole shape is regular, the no burr of periphery, precision height, the uniform hole making drill of water outlet.
The purpose of this utility model can realize by following measure:
A kind of hole making drill contains handle etc.; On handle, be connected with sliding bolt cover, in sliding bolt cover, be placed with sliding bolt, sliding bolt by block key with push away cap and link; Be associated with the pin folder at the sliding bolt cover other end, outside the pin folder, be with the pin chuck; Be fixed with hollow needle on the pin folder, be installed with cleansing pin in hollow needle, the spring on cleansing pin top and the block key links; Outside sliding bolt cover, be with needle guard in addition.
The utility model has following advantage compared to existing technology:
1, the utility model is pricked the hole with the hollow needle of rule on plastic tube wall, thereby the circular hole hole shape rule of pricking out, pore size equate, precision is high, and the no burr of its periphery; Thereby its water outlet is even.
2, the utility model is provided with movably cleansing pin in hollow needle, and the circular block that hollow needle can be cut down is disclosed in hollow needle.
3, the utility model is simple in structure, easy to use.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1 is a structural representation of the present utility model:
1-needle guard, 2-hollow needle, 3-pin chuck, 4-pin folder
5-cleansing pin, 6-spring 7-cunning bolt cover 8-push away cap
9-block key 10-cunning bolt 11-handle
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1 embodiment is described in further detail:
With reference to Fig. 1, a kind of hole making drill has closed handle 11 etc.; On handle 11, be connected with sliding bolt cover 7, in sliding bolt cover 7, be placed with sliding bolt 10, sliding bolt 10 by block key 9 with push away cap 8 and link; Overlap 7 other ends at sliding bolt and be associated with pin folder 4, outside pin folder 4, be with pin chuck 3; Be fixed with hollow needle 2 on pin folder 4, be installed with cleansing pin 5 in hollow needle 2, the spring 6 on cleansing pin 5 tops and the block key 9 links; Outside sliding bolt cover 7, be with needle guard 1 in addition.
Operation principle of the present utility model is as follows:
