Description

Automatic knotting device for bundling reed bundles

Technical Field

The invention relates to a novel reed bundle knotting device, in particular to a knotting device based on automatic wire pushing-manual wire pressing.

Background

The situation of the desertification of China is very severe, China is one of the countries with serious desertification in the world, and according to statistics, the desertification area of the land is increased only at the speed of 2460 square kilometers every year since the 70 s, so that the desertification control is imperative, wherein the most important method is wind prevention and sand fixation;

the sand-fixing principle of the reed bundle grass grid engineering is to increase the roughness of the earth surface and change the wind speed profile on the earth surface, thereby weakening the wind speed of the ground layer, reducing the effectiveness of the actual wind action and controlling the wind speed. The action mechanism is as follows:

(1) the roughness of the earth surface is increased, and the wind speed of the near-ground layer is weakened;

(2) cause a change in the flow field structure;

(3) the shape of the airflow field and the ground surface in the reed bundle grass square sand barrier is changed;

the reed bundle grass square can reduce the airflow speed of the near-surface layer and the sand conveying capacity of the airflow by increasing the surface roughness, and change the characteristic that the sand carrying amount of the wind sand flow is distributed along with the height; the roughness of the 1 m multiplied by 1 m reed bundle grass grid sand barrier is improved by 200-400 times compared with that of a quicksand area, the sand conveying rate is only 0.2-1.0% of that of the quicksand area, the wind speed of the 2m reed bundle grass grid is reduced by 26% compared with that of the quicksand area, and the wind speed of the 0.5m reed bundle grass grid is reduced by 20-40% compared with that of the quicksand area;

after the reed strawberries grid sand barriers are arranged on a moving dune, the humidity of a sand layer with the thickness of 2m can be increased from 1 percent to 3 to 4 percent, the sand soil moisture condition is obviously improved, the survival rate and the growth index of the sand-fixing plants planted in the reed strawberries grid sand barriers are respectively increased by 69 percent and 61 to 65 percent, so the reed strawberries grid sand barriers not only play a role in fixing sand, protect the sand-fixing plants planted or sowed in the initial stage from wind erosion and sand burial, but also promote the survival and growth of the plants; therefore, there is a need for mechanical bundling of reed bundles in batches, reducing labor and improving productivity.

Disclosure of Invention

The invention aims to realize the efficient and convenient bundling of the sand-protecting barrier reed bundles.

The invention relates to an automatic knotting device for bundling reed bundles, which comprises a rack, a wire pushing-pressing mechanism, a knotting mechanism and a power device, and is characterized in that the rack, a special knotted iron wire arranged in the rack and the wire pushing-pressing mechanism arranged in the rack are arranged on the rack, the knotting mechanism is arranged on the rack, and the power device is arranged right below the knotting mechanism.

The automatic knotting device for bundling reed bundles is characterized in that a pre-tightening spring and a spring supporting rod of a wire pushing mechanism are installed in a groove of a rack, a knotted iron wire pre-tightening plate is pushed by the elasticity of the pre-tightening spring to keep knotted iron wires always under a wire pressing plate, and the wire pressing mechanism moves in a slide way in the rack through the wire pressing plate to enable the knotted iron wires to surround the reed bundles.

The automatic knotting device for bundling reed bundles is characterized in that the fixing frame is arranged on the rack, and the knotter of the knotting mechanism is arranged on the rack and provides power through the driving motor arranged in the rack.

The working process of the invention is as follows: the machine can carry out a plurality of times of bundling operations of autonomously controlling the bundling interval on reed bundles of 3-5cm, firstly manually put knotted iron wires of special shapes into a frame, the pre-tightening spring of the wire pushing mechanism and the pre-tightening plate of the knotted iron wire tightly press the knotted iron wire and send the knotted iron wire to the position under the wire pressing plate, then the single bundle of reeds which are already split into bundles is stretched into a middle arc-shaped groove of the frame, the bundling position is automatically controlled, then the wire pressing plate is pressed manually, so that the wire pressing plate slides downwards on the slideway of the frame, and the single knotted iron wire falls onto the reed bundle by the extrusion of the wire pressing plate, the knotting iron wires are contacted with the arc-shaped area under the frame to be stressed, bent and crossed by continuously pressing the wire pressing plate, the crossed iron wires are knotted by the rotating knotter, after the single knot is finished, and stopping the knotter to rotate, moving the reed bundles to control the knotting distance, and repeating the steps to finish the bundling of the reed bundles with the autonomously controlled bundling distance.

The invention aims to bundle reed bundles for sand barriers in batches, simplify the bundling process of the reed bundles, improve the productivity, reduce the labor power of workers, save the production cost and the like.
