In order to facilitate the understanding of the present invention by those skilled in the art, the specific embodiments of the present invention are described below with reference to the accompanying drawings.

In the description of the present invention, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense, unless otherwise expressly specified and limited, for example, it may be a fixed connection or a detachable connection connection, or integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components; for those of ordinary skill in the art, The specific meanings of the above terms in the present invention can be understood through specific situations.

As shown in Figure 1, it is a schematic diagram of the current structure of using a crawler tractor to pull the drip irrigation belt. The drip irrigation belt is clamped by the upper crawler and the lower crawler (the crawler is rubber) to form traction; even if The crawler is made of rubber and has a certain elasticity; as shown in Figure 2, the extrusion of the two will cause pressure injury to the drip irrigation belt (because the inner wall of the drip irrigation belt is directly bent, and because the drip irrigation belt is a tubular structure, it is During the extrusion process, the extrusion force will squeeze the upper and lower corners of the drip irrigation tape to produce insignificant crease (or indentation). Although the indentation is not obvious, the indentation caused by high-strength extrusion will cause drip irrigation. The belt produces irreparable damage as a whole, and this problem is more serious especially in winter; after the indentation is enlarged, it is found that several cracked fine lines will be formed at the indentation position; the invention provides a drip irrigation belt production traction assembly, It includes a traction wheel 1 that pulls and conveys the drip irrigation belt through friction; also includes a force application unit 2 that applies non-contact pressure to the drip irrigation belt; the material first forms a molten state in the melting furnace, and the molten material is extruded from the water through the filter mesh. After extrusion, after cooling and forming, the drip irrigation belt bypasses the traction wheel 1, and the drip irrigation belt realizes the driving traction of the drip irrigation belt through friction on the traction wheel 1; the force applying unit 2 is used to apply non-contact force to the drip irrigation belt , so that the drip irrigation belt is tensioned to generate tension; the tensioned drip irrigation belt can be in close contact with one side of the traction wheel 1 to increase the frictional traction; after the driving device 19 drives the traction wheel 1 to rotate, the drip irrigation belt is driven by traction, this During the process, the traction wheel 1 and the force-applying unit 2 do not clamp and squeeze the drip irrigation belt, so the edge of the drip irrigation belt will not be indented; no internal injury or trauma of any kind is caused to the drip irrigation belt.

As shown in Figures 3-6, the above-mentioned force applying unit 2 is used to apply a non-contact force to the drip irrigation belt. One embodiment is to blow the drip irrigation belt directly through air pressure, so that the drip irrigation belt is tensioned to generate tension; At the position corresponding to the traction wheel 1, it is facing the drip irrigation belt; the air pressure nozzle can be directly connected with the high-pressure air source in the factory, and the drip irrigation belt is blown directly through the external high-pressure air source, and the air pressure makes the drip irrigation belt close to the traction wheel 1, so that the Increase friction to ensure traction and conveyance; an air pump can also be set up to generate high-pressure gas through the air pump to output from the air pressure nozzle; since the drip irrigation belt is just extruded, after the initial cooling by the cooling device, there is incomplete cooling. At this time, the drip irrigation belt The texture is relatively soft; if the existing extrusion method is used, it is easy to produce indentation before it is completely formed; the drip irrigation belt is made close to the traction wheel 1 by air pressure, which not only increases the friction force to ensure the traction and transportation, but also the air pressure can also affect the drip irrigation.

Channel 9; the first channel 7 communicates with the open space, the second channel 8 communicates with the sealed space; and the vertical height of the first channel 7 is located between the overflow channel 5 and the partition 6; the vertical height of the third channel 9 Located between the second channel 8 and the first channel 7; the sealed space is connected to the return main pipe 11, the return main pipe 11 is provided with a number of return branch pipes 12, and the other side of the return branch pipe 12 extends to the interior of the storage tank 3 and is connected with the hydraulic nozzle; At the same time, a water pump 10 is provided on the return main pipe 11; the water in the sealed space is continuously pumped out by the water pump 10 through the hydraulic nozzle to apply pressure to the drip irrigation belt, so that the drip irrigation belt is tensioned to generate tension; and the hydraulic pressure can also be applied to the drip irrigation belt. Secondary cooling; at the same time, because the drip irrigation belt needs to be punched after cooling; after the drip irrigation belt is pierced by the punching needle, small particles will adhere to the drip irrigation belt and will be washed down together; the external water pipe will also The water storage tank 3 is replenished and slowly replenished; the water on the surface of the storage tank 3 is discharged from the overflow channel 5 to the open space when the predetermined threshold is exceeded; the small particles of the drip irrigation belt floating on the water surface of the storage tank 3 are also discharged by the overflow; this When the open space has the effect of secondary precipitation, the impurities with large particles are deposited on the bottom of the open space; the floating liquid containing small particles of drip irrigation tape enters the inner cavity of the overflow tank 4 from the first channel 7, and the relatively clean part Return to the sealed space through the second channel 8, and continue to spray from the hydraulic nozzle through the return main pipe 11; the drip irrigation tape containing small particles is discharged from the third channel 9.
