Water-saving irrigation anti-blocking fertilizer applicator

Technical Field

The invention relates to the field of application of crop irrigation devices, in particular to a water-saving irrigation anti-blocking fertilizer applying device.

Background

Along with better and better living conditions, rural areas develop to cities more and more quickly, the traditional crop planting area is smaller and smaller, in order to meet the living requirements of people, more and more crops are planted in batches, turned over, sowed, fertilized, watered and harvested basically through machinery, the workload of people for planting the crops is reduced to a great extent, and the yield of the crops is improved due to a scientific planting mode. There are two very important links in the in-process of crops planting, the link of watering and fertilization, when weather is arid, when rainfall is not fallen for a long time, crops are difficult to maintain the demand of growing through drawing sufficient moisture from soil, lead to crops wither because of lack of moisture easily, or because crops planting area is big, lead to the fertilization inhomogeneous very easily in the fertilization, make some crops be difficult to obtain sufficient nutrient, lead to crops output to descend.

The traditional mode of irrigating crops generally adopts a spray irrigation mode to water crops, the places where the crops are planted in batches are generally in places with big rivers, reservoirs and lakes to ensure sufficient water sources, water in the big rivers, the reservoirs and the lakes is conveyed to the field through a water pump, water flows to a spray head at the tail end of a pipeline rapidly under the action of high pressure, and the water is sprayed to the crops from the spray head in an umbrella shape under the action of the pressure.

Although the sprinkling irrigation is than irrigation ditch irrigation water conservation, the sprinkling irrigation faces a more serious problem, contain more silt and impurity in the river water or the river water of watering exactly, under the condition through effective filtration, the outlet pipe of sprinkling irrigation shower nozzle is blockked up very easily to incrustation scale and silt, not only influence the effect of watering, make crops can not obtain even watering, and can cover bigger area for making shower nozzle spun hydroenergy, the position that the shower nozzle set up is generally all higher, so when wanting to clear up incrustation scale and silt in the sprinkling irrigation outlet pipe, it is very inconvenient to operate. Also someone attempts at present to add the filter screen at the in-process of sprinkling irrigation, and fertilize through concatenating venturi with liquid fertilizer suction and sneaking into aquatic simultaneously, through the combination of sprinkling irrigation and fertilization, it has practiced thrift the amount of labour to a certain extent, but still has some problems in its use: for example, filterable silt can constantly siltation filter screen, leads to the head loss of water pump bigger and bigger, influences terminal sprinkling irrigation pressure and venturi to the suction capacity of liquid manure, consequently need to perfect current sprinkling irrigation device to overcome above-mentioned problem.

Aiming at the defects of the prior art, the invention aims to provide a water-fertilizer mixing device which can treat silt of irrigation water so as to reduce the influence of the silt on a spray head and solve the problem of inaccurate water-fertilizer mixing proportion caused by continuous reduction of a water pump pressure head.

In order to achieve the purpose, the invention provides a water-saving irrigation anti-blocking fertilizer application device, which comprises a cylindrical barrel, a funnel-shaped barrel, an impurity collecting chamber, a filter screen, a first spring, a limiting block, a screw rod and an arc-shaped adjusting plate, wherein the cylindrical barrel is provided with a water inlet pipe, the water inlet pipe is square, the funnel-shaped barrel is connected below the cylindrical barrel, the funnel-shaped barrel is in an inverted round table shape, the lower part of the funnel-shaped barrel is connected with the impurity collecting chamber, a water outlet pipe is arranged right above the axis of the cylindrical barrel, the lower part of the water outlet pipe is connected with a corrugated pipe, the lower end of the corrugated pipe is connected with the filter screen, the first spring is arranged in the filter screen, an adjusting cavity for accommodating the arc-shaped adjusting plate is arranged between the outer wall of the water inlet pipe and the, the adjusting cavity is internally provided with a screw rod for pushing the arc-shaped adjusting plate, one end of the screw rod outside the adjusting cavity is provided with a handle, the other end of the screw rod is hinged with the limiting block, a second spring with a transmission effect is arranged between the screw rod and the arc-shaped adjusting plate, one end of the second spring is fixedly connected onto the limiting block, the other end of the second spring is fixedly connected with one end of the arc-shaped adjusting plate, the circle center of the rotating track where the arc is adjusted coincides with the circle center of the bucket-shaped barrel, the inner wall of the arc-shaped adjusting plate is provided with a discharge chute, and the direction of the discharge chute is.

The working mode of the invention is as follows, when high-speed water flow passes through the water inlet pipe, the size of the water inlet pipe is controlled by adjusting the arc-shaped adjusting plate, not only the initial speed of the water flow and the quicksand in the water flow can be increased, but also the water flow and the quicksand in the water flow can be closer to the inner wall of the device, and the quicksand can impact the inner wall of the cylindrical barrel by a smaller distance when the centrifugal force is increased. After water flow enters the device, the water flow enters the cylindrical barrel body along a tangent line to make rotary motion, and at the moment, the heavy silt can be thrown to the inner wall of the device and moves downwards under the action of gravity to fall into the impurity collecting chamber. When rivers move the infundibulate barrel of inverted circular truncated cone shape, the heavier silt of quality will be got rid of to the inner wall of infundibulate barrel, under the effect of gravity, fall into the impurity collecting chamber of device bottom in, high-speed rivers make rivers draw close to the centre because of the radial shrink of infundibulate barrel, form a whirl from bottom to top, the whirl discharges from the outlet pipe of device through the filter screen. Because some impurities with lighter weight in the water flow can move upwards along with the rotational flow, a filter screen is connected below the water outlet pipe of the device and can intercept the impurities with light weight. The material suction pipe is connected with required fertilizer water or pesticide water, when high-speed water flows in the inner rotation of the cylindrical barrel, the water flows through the inner side of the arc-shaped plate, the discharge chute on the arc-shaped adjusting plate increases the space through which the water flows, negative pressure can be generated between the arc-shaped adjusting plate in the adjusting cavity and the outer wall of the cylindrical barrel, and therefore the fertilizer water and the pesticide water enter the adjusting cavity from the material suction pipe under the action of atmospheric pressure, flow into the cylindrical barrel from the other side separated by the arc-shaped adjusting plate, and are discharged after the inner wall of the device is fully mixed with the high-speed water flow.

To synthesize and see, this device can filter out the impurity of high-speed rivers with the aquatic under dual filtration to can also carry out the intensive mixing back with pesticide water and fertilizer water and discharge by the outlet pipe, not only solve the problem that spray irrigation shower nozzle and suction pump pressure head blockked up easily, still make the fertilization of crops and pesticide spray irrigation become even, improve the output of crops.

Further, the inlet tube sets up on the tangential direction of cylindrical barrel, and the benefit of adopting the tangent line to intake lies in making high-speed rivers make rotary motion along the inner wall, increases centrifugal force.

Furthermore, the material suction pipe is provided with a flow regulating valve, and the advantage of the flow regulating valve is that the quantity of the sucked materials of the material suction pipe can be regulated by regulating the valve, so that the concentration of the water and the fertilizer can be regulated.

Furthermore, the filter screen is made of stainless steel, so that the supporting force of the filter screen is improved, and the corrosion damage of the fertilizer liquid medicine filter screen is effectively avoided.

Furthermore, the bottom end of the filter screen is a spherical surface, which has the advantages that the contact area between the spherical surface and the rotational flow is increased, the smooth surface enables the transition capacity of the bottom of the filter screen to be stronger, and the resistance of the rotational flow passing through the filter screen is reduced.

The specific implementation process is as follows:

as shown in fig. 1 to 6: the holistic outward appearance of the device forms for a plurality of round platform shape are connected, have seted up square inlet tube 1 at the tangential direction on the surface of device, establish inlet tube 1 into square reason because, when high-speed rivers entered, rivers moved along the tangential direction of device inner wall, can the fastest participate in the rotation. An adjusting cavity 14 is arranged between a square water inlet pipe and a cylindrical barrel, a material sucking pipe 2 is arranged inside the adjusting cavity 14, the material sucking pipe 2 is arranged in the horizontal tangential direction of the cylindrical barrel 3, the other end of the material sucking pipe 2 can be connected with a container for containing fertilizer liquid or pesticide liquid, when high-speed water flows through the water inlet pipe 1 and enters the cylindrical barrel 3 to perform high-speed rotary motion, because a gap is formed between the adjusting cavity 14 and the other side of a separated water inlet, the water flows through a discharge groove 15 on an arc-shaped adjusting plate 10 in the adjusting cavity 14, and because the flow area of the water flow is increased, negative pressure can be generated in the gap between the outer wall of the cylindrical barrel 3 and the arc-shaped adjusting plate 10, so that the fertilizer water and the pesticide liquid can enter the gap between the adjusting cavity 14 and the arc-shaped adjusting plate 10 from the material sucking pipe 2 under the action of atmospheric pressure and flow, and the high-speed water flow is fully mixed on the inner wall of the device and then is discharged from the water outlet pipe 7.

The screw rod 11 is rotated by the handle 13 to stretch back and forth, under the transmission action of the second spring 16, the arc-shaped adjusting plate 10 can change the size of the channel at the tail end of the water inlet pipe 1, the smaller the channel is adjusted, the smaller the water inlet channel of high-speed water flow is, and the water inlet amount is determined by the water suction pump, so the initial speed of water inlet can be increased. The reason for using second spring 16 as the transmission original paper is that the spring can adapt to the range of advancing in adjusting the chamber 14, play better transmission effect, not only so arc regulating plate 10 can also get into the high-speed rivers of inlet tube 1 with the guide, the outer wall from cylindrical barrel 3 gets into, just can participate in rotary motion at the very first time that gets into, and arc regulating plate 10's concave surface is in cylindrical barrel 3's outer wall one side, the clearance between arc regulating plate 10 and the cylindrical barrel 3 outer wall has been increased, the circulation ability of inhaling material effect and fertilizer water has been strengthened.

The inside annular groove that is provided with of lower extreme of screw rod 11, stopper 17 are located the recess of screw rod 11, and articulated benefit lies in between screw rod 11 and the stopper 17, and when rotatory screw rod 11, second spring 16 can not be taken in the rotation of screw rod 11, only can compress second spring 16, reduces the transmission resistance when making second spring 16 play driven effect.

Filter screen 8 is the cylinder shape of spherical surface for the bottom, has all seted up the align to grid aperture at filter screen 8's side and bottom surface, and rivers can get into from filter screen 8's all directions, and the spherical surface design in bottom has not only strengthened the transition ability, has still increased the area of contact with the whirl, falls the resistance that filter screen 8 formed to water to minimum, and the diameter of aperture is 4mm on filter screen 8, and the aperture of 4mm diameter can filter the impurity that the quality is lighter. Bellows 12 is being connected to the upper end of filter screen, and bellows 12 can drive filter screen 8 and shake under the impact of rotatory rivers, can shake off some impurity during the swing, still because the swing can change the angle of intaking of the filtration pore on the filter screen 8, makes the filtration pore that has slight impurity jam can intake from the direction of difference, has reduced the resistance of intaking. The outlet pipe 7 is being connected to bellows 12 upper end, and rivers or lake water through double filtration are discharged from outlet pipe 7, have first spring 9 in filter screen 8, and the diameter ratio of first spring 9 is little less than filter screen 8, when guaranteeing that filter screen 8 is not by extrusion deformation, first spring vibrates under the impact of rivers, can also reach the clear function of filter screen 8. The spiral direction of first spring 9 is unanimous with the spiral direction of whirl, and the aim at of first spring 9, the helical shape of first spring 9 not only can spiral water guide, still supports filter screen 8 and bellows 12 because the radial little characteristics of warping of first spring 9 prevent that impurity from attaching to the filter screen, blocks up the filtration pore of filter screen to avoid rivers to get into the resistance increase of filter screen, with bellows 12 extrusion deformation.
