Description

Salt-soda soil anatonosis Special punching machine knife tubular construction

Technical field

This utility model is related to a kind of salt-soda soil anatonosis Special punching machine knife tubular construction.

Background technology

In existing technology, alkaline land soil is easily hardened, hinders sky gas and water and nutrient penetrates soil layer and reaches root system, The strong influence healthy growth of vegetation.Punching function effectively eliminate soil compaction, make salt-soda soil ventilate, contribute to water, fertilizer, Medicine it is isotonic enter soil.

Hollow pipe knife in existing puncher, after drilling, the soil dug up in hole is taken out from hole in hollow pipe knife Easily fallen in hole again when going out, cause effect on driving birds is not good of punching, the low problem of perforating efficiency.

The content of the invention

Problem to be solved in the utility model is to provide a kind of salt-soda soil anatonosis Special punching machine knife tubular construction, overcomes existing The deficiency having in technology.

To solve above-mentioned technical problem, the technical solution adopted in the utility model is：Salt-soda soil anatonosis Special punching machine knife Tubular construction, including hollow pipe knife, cylinder, push rod and intermediate plate, the hollow pipe knife include hollow pipe and cutter head, and the cutter head is located at The lower end of the hollow pipe, is located on the hollow pipe at the cutter head and has folder provincialism, and the internal diameter of the folder provincialism is big It is with the space that pass through can the intermediate plate on the internal diameter at other positions of hollow pipe, the side wall of the folder provincialism, described The lower edge of intermediate plate is located in the folder provincialism, and the upper edge of the intermediate plate is located at outside the hollow pipe, the top of the hollow pipe With the through hole through the side wall of hollow pipe, the push rod passes through the two ends of the through hole, the push rod to stretch out described respectively Outside hollow pipe, the connecting rod of one end of the push rod and the cylinder is fixed, and the medial surface of the other end and the intermediate plate is fixed, described Cylinder is fixed on the outer wall of the hollow pipe.

Further, the outer wall of the folder provincialism is seamlessly transitted with the outer wall of the hollow pipe.

This utility model has the advantages and positive effects that：Due to adopting above-mentioned technical proposal, can be while punching It is during the soil zone dug up in hole is portalled, it is to avoid the soil dug up drops in hole, practical convenient；With simple structure, dimension Repair conveniently, the advantages of processing cost is low, perforating efficiency is high.

Fig. 2 is half section structural representation in Fig. 1；

In figure：1- hollow pipes；2- cutter heads；3- presss from both sides provincialism；4- intermediate plates；5- cylinders；6- push rods.

Specific embodiment

As shown in Figure 1, 2, this utility model provides a kind of salt-soda soil anatonosis Special punching machine knife tubular construction, including hollow pipe Knife, cylinder 5, push rod 6 and intermediate plate 4, hollow pipe knife include hollow pipe 1 and cutter head 2, and cutter head 2 is located at the lower end of hollow pipe 1, hollow It is located on pipe 1 at cutter head 2 and there is folder provincialism 3, presss from both sides the internal diameter of the internal diameter more than 1 other positions of hollow pipe of provincialism 3, press from both sides provincialism With the space that pass through can intermediate plate 4 on 3 side wall, the lower edge of intermediate plate 4 is located in folder provincialism 3, and the upper edge of intermediate plate 4 is positioned at hollow Outside pipe 1, the top of hollow pipe 1 has the through hole through 1 side wall of hollow pipe, and push rod 6 passes through the two ends of through hole, push rod 6 to distinguish Stretch out outside hollow pipe 1, one end of push rod 6 is fixed with the connecting rod of cylinder 5, the medial surface of the other end and intermediate plate 4 is fixed, cylinder 5 is solid On the outer wall of hollow pipe 1.

Before hollow pipe knife insertion soil layer, push rod 6 is by intermediate plate 4 near tension at 1 outer wall of hollow pipe, so that hollow When pipe knife stretches into soil layer, the bottom of intermediate plate 4 is located in folder provincialism 3, it is to avoid to causing to stop into the hack in hollow pipe 1, when When hollow pipe knife is extracted out from hole, cylinder 5 drives push rod 6 by the top of intermediate plate 4 to the direction ejection away from 1 outer wall of hollow pipe, Now the bottom of intermediate plate 4 is moved towards 1 axis direction of hollow pipe, will be clamped into the hack in hollow pipe 1 with this, it is to avoid hack Drop from hollow pipe 1.

The outer wall of folder provincialism 3 is seamlessly transitted with the outer wall of hollow pipe 1.The outer wall for pressing from both sides provincialism 3 is avoided to enter to bury to hollow pipe 1 Cause to hinder during layer.

Above embodiment of the present utility model is described in detail, but the content has been only of the present utility model preferable Embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all according to this utility model application range made it is equal Deng change and improvement etc., still all should belong within patent covering scope of the present utility model.
