Description

Water-fertilizer precise-mixing farmland irrigation equipment

Technical Field

The utility model relates to an agricultural implement, in particular to water-fertilizer precise mixing farmland irrigation equipment.

Background

Application of fertilizers is an important measure for increasing grain yield. The prior chemical fertilizer is buried in soil layer by ditching or punching, and the method has the advantages of good fertilizer efficiency, high operation cost and low comprehensive benefit. In recent years, farmers combine water-saving irrigation to dissolve chemical fertilizers in water, and apply fertilizers along with the water while irrigating, which is also called as water-fertilizer integration. The method is simple and practical, has considerable comprehensive benefit, and is popular with farmers. However, this approach also has a number of disadvantages, most notably uneven fertilisation. In places with sufficient manpower, most people scatter fertilizers into the water channel, and a plurality of fertilizer bags with insufficient manpower are placed in the water channel. Practice has shown that the above method does not allow for uniform dissolution of fertilizer in the water stream. To solve this problem, there are some water sources equipped with a dissolving tank, in which fertilizer is dissolved, and fertilizer water is injected into the canal. Although the effect of the mode is improved, the water and fertilizer in the dissolving tank are fed in and discharged out simultaneously, so that the proportion of the water and fertilizer and the dissolving degree are unstable, and the purpose of uniformity is not achieved. The uneven harm of fertilizer is great, and the local crops with less fertilizer can not grow well. The places with more fertilizer not only waste fertilizer, but also burn seedlings. In recent years, various water and fertilizer integrated devices adopting high-tech intelligent technology are introduced in the market, so that not only can the water and fertilizer be uniformly mixed, but also the water and fertilizer can be applied to crops at proper temperature and quantity. However, the equipment has a complex structure and high manufacturing cost, can only be used in facility agriculture such as nursery and the like at present, and cannot be widely used in fields. Therefore, the existing field crops need a simple and low-cost large-scale water-fertilizer fine mixing device.

Quantitative water is injected into the dissolution tank, fertilizer in the fertilizer bucket quantitatively enters the dissolution tank, fertilizer water with certain concentration is fully dissolved, the fertilizer water is put into the fertilizer tank, and quantitative and uniform injection is performed on irrigation water, so that the purposes of uniform water and fertilizer and accurate proportioning are achieved. Many embodiments, the present example recommends the following configuration:

1 (one) and combining with fig. 2, the upper part of the fertilizer hopper is a cylinder or a cube, the middle lower part is a cone, the bottom is provided with an opening 1.1, and the opening is provided with a rotary drum 1.2 capable of quantitatively adding fertilizer.

As can be seen by combining fig. 3 and 4, the rotary drum is mounted at the opening at the lower end of the fertilizer hopper through the rotary shaft 1.2.1, and the opening of the fertilizer hopper is tightly blocked, so that fertilizer cannot leak from the opening. The rotary drum can rotate under the drive of a rotary drum motor 1.2.4 or a transmission mechanism, and one side of the rotary drum is provided with a fertilizer inlet 1.2.2. When the fertilizer inlet is upward, the fertilizer in the fertilizer bucket can enter the rotary drum. When the fertilizer inlet is downward, the fertilizer in the rotary drum falls into the dissolution tank 2 below.

(two), combine the figure 5 to see, dissolving tank 2 is a container, and the upper portion is equipped with inlet tube 2.7, is equipped with water pump 2.8 on the inlet tube, and the water pump can be driven by the water pump motor and is filled into the dissolving tank. A liquid discharge port 2.2 is arranged below the dissolving tank, and a liquid discharge valve 2.3 is arranged on the liquid discharge port.

In the figure, a floater 2.4 is arranged in the dissolving tank, a touch rod 2.10 is arranged at the upper part of the floater, and the touch rod is matched with a touch switch; the touch switch is provided with a rotary drum switch 2.5 for controlling the rotary drum to rotate, and a parking switch 2.6 for stopping the rotation of the water pump of the water inlet pipe and controlling the liquid discharge valve to start and stop from bottom to top.

To make the float more stable in operation, the float is slidingly engaged with the upright slide 2.9.

In order to make the mechanism more compact, the tactile switches, including the drum switch 2.5 and the park switch 2.6, may be provided on the tank wall of the dissolving tank as shown. In order to prevent liquid from entering the switch, a soft waterproof sleeve 2.9 is arranged outside the rotary drum switch 2.5 and the parking switch 2.6 as shown in fig. 6.

A comparatively optimized drum structure can be seen in connection with fig. 7, 8: the barrel wall of the rotary drum is cylindrical, at least half of the barrel walls are airtight, a plurality of fertilizer inlets 1.2.2 are formed in the other barrel walls along the direction of the central axis of the cylinder, and the barrel walls between adjacent fertilizer inlets are fertilizer scraping teeth 1.2.3 with triangular sections. The rotating drum can scrape the fertilizer better during rotation, so that the rotating drum is filled with the fertilizer.

A fertilizer water tank 3 which can hold fertilizer water is arranged below the dissolving tank. As can be seen in fig. 9 and 10, the volume of the fertilizer tank is larger than that of the dissolving tank, and the upper opening 3.1 of the fertilizer tank is opposite to the liquid outlet of the dissolving tank. The inside of the fertilizer pot is provided with a water float 3.2, the water float is provided with a touch head 3.3, and the touch head is matched with a water injection switch 3.4. When the water level of the fertilizer water tank drops to the set position, the touch head presses the water injection switch, so that the water pump of the water inlet pipe of the upper dissolving tank is started to inject water into the dissolving tank. The water injection switch is arranged on the wall of the fertilizer water tank, and a soft waterproof sleeve is also arranged outside the water injection switch. In order to make the running of the water float more stable, the water float is placed in the vertical chute 3.5 and can slide up and down along the chute.

In the figure, a fertilizer water pipe 3.6 is arranged at the lower part of the fertilizer water tank, and a flow valve 3.7 is arranged on the fertilizer water pipe. As can be seen from fig. 1, the openings of the fertilizer water pipes are opposite to the irrigation water pipes 4 or channels for irrigation to the farmland.

The mechanism can realize quantitative combination of fertilizer and irrigation water, and the working process of the whole device is shown in figure 11: when in use, firstly, the fertilizer with good fluidity is filled into the fertilizer hopper, and then the water pump of the water inlet pipe of the dissolving tank is started to fill water into the dissolving tank. The water may be extracted from a dedicated source of water or from irrigation water. With the increase of the water level, the floater rises to touch the rotary drum switch to enable the rotary drum to rotate at a fixed angle, and 1-3 is generally set to be suitable, so that quantitative chemical fertilizer can be put into the dissolving tank. At this time, the stirrer in the dissolution tank is started to be operated, so that the fertilizer is fully dissolved in the water. The float continues to move upwards, and the start-stop switch can be touched when the set water level is reached. The start-stop switch is a duplex switch, on one hand, the water pump stops rotating, and meanwhile, the solution port at the lower part of the dissolving tank is opened, and all the solution in the tank is put into the fertilizer-water tank below. This process can be repeated under human control until the tank is filled. At this time, the water of the irrigation water pipe has arrived, the flow valve of the fertilizer water pipe below the fertilizer water tank is opened, quantitative fertilizer water is injected into the irrigation water pipe from the lower opening of the fertilizer water pipe, and the quantitative fertilizer water is uniformly combined with the irrigation water to flow to farmlands. After that, every time the water level in the fertilizer water tank drops to the set position, the water float descends along with the water level, the touch head 3.3 of the water float touches the water injection switch 3.4, the water pump of the dissolving tank is started to inject water into the dissolving tank, and then the rotary drum below the fertilizer hopper is triggered to rotate, so that the process can be repeated until the irrigation of farmlands is completed.

As can be seen from the above, the relationship between the structural parameters and the operating parameters of the various components of the set of equipment is relatively simple and can be expressed as follows: irrigation water quantity: farmland water consumption = irrigation area (mu), fertilizer consumption/mu X irrigation area (mu) = fertilizer consumption, fertilizer consumption: drum capacity = drum revolution, whereby the rotational speed of the drum is determined, the capacity of the dissolution tank is determined with the amount of water to dissolve the fertilizer, and the structural parameters of the water pump, the control switch of the drum are determined. It follows that the working performance of the device is fully achievable.

Second embodiment: only the structure of the irrigation pipe is modified on the basis of the first embodiment. As shown in fig. 12 and 13, a turbulence chamber 4.1 is added to the irrigation pipe 4. The turbulence chamber can be a circular or square or polygonal container, and the diameter of the turbulence chamber is larger than that of the irrigation water pipe, and can be more than 2 times of that of the irrigation water pipe. A plurality of vertical strip-shaped damping grids 4.2 are arranged in the damping grid. The turbulent flow chamber is arranged between the device and the farmland, and after irrigation water flow enters the turbulent flow chamber, the irrigation water flow is blocked by the damping grid to form disordered turbulent flow. Thus, the fertilizer and the irrigation water can be more uniformly mixed together, the phenomenon of uneven quantity is avoided, and the irrigation effect is obviously enhanced.

Third embodiment: the optimization is performed on the basis of the previous embodiments. As shown in fig. 14, the touch switch is mounted on a switch board, the switch board is mounted on the dissolution tank, and the touch rod of the floater extends upwards to pass through the upper opening of the dissolution tank to be matched with the touch switch. The water injection switch is arranged on the switch board, the switch board is arranged on the fertilizer tank, and the touch head on the water float extends upwards out of the fertilizer tank to be matched with the water injection switch for starting the water inlet pipe water pump of the dissolving tank.

Fourth embodiment: the improvement is based on the foregoing embodiments. As shown in fig. 15, a stirrer 3.8 is arranged below the opening of the fertilizer water pipe, and consists of a vertical shaft and a propeller, wherein the propeller penetrates into the irrigation water pipe or the canal. During operation, the screw rotates under the impact of water flow, so that the fertilizer and the water can be stirred, and the fertilizer and the water are fully mixed.

Fifth embodiment: the remote control device is added on the basis of the previous embodiment. The remote control device can utilize the electromechanical well water pump-mobile phone control device which is already used in rural areas at present, such as the mobile phone remote control device shown in fig. 16, to remotely control each motor of the equipment. Of course, as shown in fig. 17, only the on-off flow valve of the fertilizer water pipe may be remotely controlled. After a receiving circuit is installed on a motor line of a fertilizer water pipe flow valve, a person performs preparation work, then a mobile phone is used for controlling the opening action of a water discharge pipe flow valve motor through a network to quantitatively throw fertilizer water into irrigation water, when the water level in a fertilizer water tank drops, a water float descends to trigger a water injection switch to enable a dissolving tank to inject water, a float ascends to trigger a rotating drum of the fertilizer hopper to act, quantitative fertilizer is thrown into the dissolving tank, when the water level of the dissolving tank reaches a set value, the float triggers an on-off switch to stop the work of a water pump, a solution port is opened, and the fertilizer water is put into the fertilizer water tank. This is repeated until the field irrigation process is completed.
