Detailed ways

According to Figure 1, it can be seen that the water source enters the plane overall structure from K1, enters the spraying horizontal pipe L1 through the diversion water delivery pipe S, sprays backward and downward through multiple rows of small holes, and then enters another water delivery pipe H through multiple short water delivery pipes. The root spraying transverse pipe L2 sprays backward and downward again. The water pipes S are arranged in a herringbone shape, the purpose of which is to stabilize the structure, and the main purpose is to divert the water and evenly enter the middle of both sides of the spraying horizontal pipe L1, so that the water flows evenly into the spraying horizontal pipe L1 and sprays backward and downward. The purpose of the pipe is to increase the front and rear spans of equipment spraying water during the process of slowly moving forward in the overall structure of the plane, thus increasing the water falling time at the same point on the ground to achieve the purpose of infiltrating the soil. The spraying horizontal pipes L1 and L2 are connected by multiple short water delivery pipes, the purpose of which is to stabilize the structure and enable water to flow into the spraying horizontal pipe L2 more evenly from multiple places. There are many rows of small holes in the lower part of the spray horizontal tube, so that the water is sprayed in a fan shape up and down. The number of small holes and the size of the aperture should be determined according to the water supply, that is, according to the water pressure. There is a certain water pressure, but the water pressure is not required to be too high.

Three portable walking wheels are housed below the plane overall structure, respectively below the three points A, B, and C, forming triangular subdivisions. Its function is to be used for walking and supporting, and the height of the plane overall structure can be adjusted.

Two small uprights are installed above the two points B and C, and their function is to serve as supporting uprights for the traction of cable stays when the horizontal span of the spraying tube is wide, so as to prevent the two sides of the spraying tube from drooping.

The adjustment of the width of the spraying horizontal pipe is very simple. According to the width of the land, it can be realized by connecting more or less steel pipes on both sides of the horizontal pipe, and it can be flexibly controlled according to the land.

When necessary, three sprinkler pipes can also be designed to further increase the span of the front and rear falling water, and the effect is better, but the structure is complex and can be flexibly designed according to the regional conditions.

In order to facilitate moving and storage, the farmland watering machine of the present invention has a folding function. The specific operation is to remove the diversion water delivery pipe S from the overall structure of the plane, and connect the spraying horizontal pipes from the joints D1 and D2 in the middle of the spraying horizontal pipes L1 and L2. L1 and L2 are cut into two parts, and the two sides of the spraying horizontal tube are overlapped to change the direction of the wheels, so that they can be pulled and walked, and are convenient for storage.

The traction power system includes a remote controller, a controller, a motor, a reel, and a thin wire rope. The controller, motor, and small reel are installed together, and placed several meters in front of the overall structure of the plane (a simple ground anchor is set here, and the head of the steel rod can be inserted into the ground). One end of the thin steel wire rope is wound around the reel, and the other end At the front end of the overall structure of the traction plane, the motor drives the small reel to rotate, and the small reel winds the thin wire rope, so that the overall structure of the traction plane slowly walks forward. The controllable water pressure gauge generates an induction signal according to the magnitude of the water pressure. Through the remote control, the speed of the motor is controlled, and the speed of the overall structure of the plane is also controlled. The beneficial effect of this kind of walking by power traction is: without using the road wheel guide device, the plane overall structure can walk straight forward, and also saves the complicated power driving device of the road wheel and the ground slipping device of the road wheel, Reduced the weight of the plane overall structure again.

In addition, it is equipped with a human-controlled remote control, which can control the walking speed according to the local water consumption.

In the absence of power supply, another simple traction walking scheme can be adopted: the reel is installed at the front end of the overall structure of the plane, one end of the thin steel wire rope is wound around the small reel, and the other end is fixed several meters in front of the overall structure of the plane At the place, the small reel is manually driven, and the thin steel wire rope is wound, and the reaction tension of the thin steel wire rope drives the plane overall structure to move forward. It can also be used, which takes a lot of labor and simplifies the equipment. .

The structure of attached drawing 2 is the same as that of Fig. 1. The spraying principle is the same. The water delivery pipe is changed from herringbone to trapezoidal, which further strengthens the mechanical strength and stability of the overall structure of the plane. It is suitable for equipment with a wide span of the overall structure of the plane. More places enter the spraying horizontal pipe, and the ground is poured more evenly.

Attached drawings 3 and 4 are stainless steel telescopic pipes. When in use, the telescopic pipes are stretched, one end is connected to the water source, and the other end is connected to the water inlet switch K1 of the plane overall structure. With the traction of power, the plane overall structure moves forward, compresses and expands The pipe allows water to enter the flat overall structure smoothly. When the telescopic pipe reaches the shortest, it will be stretched again to complete a cycle. Without telescopic pipes, the forward movement of the plane overall structure cannot be realized.

Attached Figure 5--Figure 10 is the "special pipe fitting" connecting the overall structure of the plane, and it is an important part. This pipe fitting is used to connect the stainless steel pipe, and the pipe head is turned outward. The whole body can be loaded and unloaded. It is easy to use and can make the small hole at the rear and lower part of the spraying horizontal tube reach the direction and angle positioning. Traditional pipe fittings do not have this capability. The materials used for special pipe fittings include malleable steel, stainless steel, and aluminum products. The functions are the same. Malleable steel pipe fittings are suitable for general farmers. Stainless steel pipe fittings are expensive and durable, and are suitable for some farmers. Aluminum pipe fittings are used for both ends and the rear of the plane overall structure. , the purpose is to save weight and prevent the ends and rear of the cross tube from sagging.

Accompanying drawing 11,12,13 are the front view of pressing wire cover respectively, the side view of pressing wire cover, two semicircle bushings. .

The specific method of use of the present invention is: the water source is extracted from the water pump, sent to the field through a soft water belt and connected with one end of the stainless steel telescopic pipe of the equipment, the water enters the water inlet of the plane overall structure through the telescopic pipe, passes through the water inlet switch K1, and then Enter the middle of both sides of the spray horizontal pipe L1 through the herringbone or trapezoidal diversion water pipe S, spray evenly backward and downward in the horizontal pipe L1, and then pass through the short water pipe H in the middle of the two horizontal pipes to enter the other In the horizontal pipe L2, it is sprayed backward and downward again. The planar structure moves forward slowly under the traction of power (about one meter per minute), and the planar overall structure moves forward while compressing the telescopic pipes until the shortest time is reached to complete a spraying cycle, and the telescopic pipes are opened again. In order not to interrupt the watering, the user is equipped with a soft water pipe of the same length as the telescopic pipe. When the telescopic pipe is stretched, it is connected to k2 as a temporary replacement, so that the equipment can spray and water without interruption. The walking speed is directly proportional to the water supply pressure. The higher the water pressure, the faster the walking, and the lower the water pressure, the slower the walking. According to the induction of the water pressure gauge, it plays a regulating role. The water consumption for watering the ground is flexible according to the actual situation of the area. Master, in use, according to the width of the land, you can adjust the width of the equipment spraying horizontal pipe, and the use of large areas requires multiple lines of watering.
