CN211973484U - Adopt spiral blade formula's extra ground nail - Google Patents

Abstract

The utility model provides an adopt spiral blade formula's overlord nail comprises sharp-pointed cutting edge, helical blade, mobile jib, locating plate, nut, draw and collude, the screw thread, the square body, and its shape of sharp-pointed cutting edge is the cusp type, and the center of helical blade encircles and puts on the central point of mobile jib and link into an integrated entity with the mobile jib, and the mobile jib is the long cylinder that steel made. The working principle is as follows: after the pile driving position is selected, the sharp-end cutting edge is aligned to the position and the spiral blade type ground nail is perpendicular to the ground, then the square body is clamped by a tool and is forcibly pressed downwards to rotate clockwise, at the moment, the square body drives the main rod and the spiral blade to rotate clockwise, and as a result, the spiral blade continuously digs soil to enable the spiral blade type ground nail to continuously go deep into the soil, and because the spiral blade can tightly bite the soil, the pulling force of the spiral blade type ground nail is far greater than that of a common pile head and is 5 times of that of the common pile head according to measurement.

Description

Adopt spiral blade formula's extra ground nail

Technical Field

The utility model relates to a ground nail for ground stake is used, specifically says so and relates to an adopt spiral blade formula's overlock ground nail.

Background

At present, the national standard method of the existing plastic greenhouse, tent and ground is that pile heads are directly driven into the ground, then the plastic greenhouse and tent are tied on the pile heads through ropes to achieve the national standard purpose with the ground, but the pile head national standard method is adopted, and because the pile heads are straight line bodies, the pile heads are easily pulled up by wind together with the greenhouse and the tent, the firmness of the pile head national standard method is not enough.

Disclosure of Invention

For overcoming the not enough of its fastness of method of present pile head country deciding, the utility model aims at providing an adopt spiral blade formula to tie the earth nail to this is strengthened the firm of pile head, the utility model discloses a solve above-mentioned technical problem and the technical scheme who adopts is: the overlord nail adopting the spiral blade type is composed of a pointed cutting edge, a group of spiral blades, a main rod, a positioning plate, a nut, two pulling hooks, a thread and a square body. The utility model discloses a spiral cutting tool, including mobile jib, spiral blade, tip cutting edge, spiral blade, the tip cutting edge set up in the left side below of mobile jib, its shape is the cusp, the tip cutting edge press and form and link into an integrated entity with the mobile jib, spiral blade be the spiral, spiral blade's center encircle the central point put and link into an integrated entity with the mobile jib, spiral blade constitute by three to four blades. The main rod is a long cylinder made of steel. The positioning plate is in a circular thin plate shape and is welded at a proper position on the upper right of the main rod. The thread is arranged between the positioning plate and the square body. The nut is connected to the screw thread. The two pull hooks are respectively welded at two sides of the nut, and the square body is positioned at the rightmost upper position of the main rod.

The utility model discloses a theory of operation is: after the pile driving position is selected, the pointed end cutting edge of the spiral blade type ground nail is aligned to the position and enables the spiral blade type ground nail to be perpendicular to the ground, then the square body is clamped by a tool and is downwards rotated clockwise forcibly, the square body drives the main rod and the spiral blade to also rotate clockwise, and as a result, the spiral blade continuously digs soil to enable the spiral blade type ground nail to continuously go deep into the soil, and the operation can be finished when the horizontal line touches the positioning plate. The nut screwed on the thread can be adjusted up and down according to actual conditions, and the pull hook welded on the two sides of the nut is used for tying a rope.

The utility model has the advantages that: because the spiral blade can tightly bite the soil at the lower part and the diameter of the lower part is larger than that of the upper part, the pull-out force of the spiral blade is far greater than that of the common pile head, and the pull-out force is measured to be 5 times of that of the common pile head.

Detailed Description

Embodiments of the invention will be described with reference to the accompanying drawings: by a tip cutting edge 1, a set of helical blade 2, a mobile jib 3, a locating plate 4, a nut 8, two draw colludes 5, a screw thread 6, a square body 7 constitutes one and adopts the earth screw of helical blade formula, tip cutting edge 1 sets up the left side below mobile jib 3, its shape is the cusp, tip cutting edge 1 is that the suppression forms and links into an integrated entity with mobile jib 3, helical blade 2 is the heliciform, the center of helical blade 2 encircles on the central point of mobile jib 3 and links into an integrated entity with mobile jib 3, helical blade 2 comprises three to four blades. The main rod 3 is a long cylinder made of steel. The positioning plate 4 is in a circular thin plate shape, and the positioning plate 4 is welded at a proper position on the upper right of the main rod 3. A thread 6 is provided between the positioning plate 4 and the square body 7. A nut 8 is attached to the thread 6. The two pull hooks 5 are respectively welded at two sides of the nut 8, and the square body 7 is positioned at the rightmost upper position of the main rod 3.
