Description

TECHNICAL FIELD

[0001] The application relates to water and fertilizer proportioning technology, in particular to a water and fertilizer proportioning control device. BACKGROUND

[0002] Water and fertilizer proportioning is an important means for improving crop yield and quality, reducing waste and pollution, and improving agricultural economic benefits. Water and fertilizer proportioning is to add and dissolve a certain amount of fertilizer into a certain amount of water for dissolving fertilizer, and then to irrigate and fertilize crops after the fertilizer is completely dissolved through stirring.

[0003] The existing water and fertilizer proportioning device is to add a certain amount of fertilizer and water for dissolving fertilizer into a proportioning barrel at one time, and then to dissolve the fertilizer into the water through stirring to form fertilizer water. The existing water and fertilizer proportioning device cannot heat the water for dissolving fertilizer, and thus cannot control the temperature of the fertilizer water. Especially in cold winter, the temperature of the water for dissolving fertilizer is too low, which not only affects the dissolution speed and dissolution effect of the fertilizer, delays the proportioning process and fertilization time, but also reduces the absorption efficiency of the low-temperature fertilizer water by plants, so that the growth demand of crops cannot be met. CONTENT OF THE INVENTION

[0004] The application provides a water and fertilizer proportioning control device to solve the problem that the existing fertilizer water proportioning device cannot heat the water for dissolving fertilizer, and cannot control the temperature of the fertilizer water during proportioning.

[0005] The application provides a water and fertilizer proportioning control device, which comprises a proportioning barrel, a water injection pipe is arranged at the top of the proportioning barrel, an agitator driven by a motor is arranged in the proportioning barrel, a feeding port is arranged on one side of the top wall of the proportioning barrel, a mesh box for receiving fertilizer is fixed in the proportioning barrel below the feeding port, a circulating pipe is vertically arranged at the side end of the proportioning barrel, the bottom of the circulating pipe is communicated with the proportioning barrel through a liquid inlet pipe, a circulating pump is arranged on the liquid inlet pipe, a liquid outlet pipe communicated with the mesh box is arranged at the top of the circulating pipe, and an electric heater is arranged in the circulating pipe.

[0006] Optionally, a fertilizer hopper is arranged above the feeding port, and a discharger communicated with the feeding port is arranged at the bottom of the fertilizer hopper.

[0007] Optionally, a gear box for transmission is arranged at the top of the proportioning barrel, the rotating shaft of the motor is in transmission connection with the agitator through the gear box, and the rotating shaft of the motor is fixed with the rotating shaft of the discharger after penetrating through the gear box.

[0008] Optionally, a water inlet is arranged at the lower end of the circulating pipe for water injection.

[0009] Optionally, a filter screen cover for filtration is arranged at one end of the liquid inlet pipe in the proportioning barrel.

[0010] Optionally, the electric heater is vertically inserted into the inside of the circulating pipe and is detachably connected with the circulating pipe.

[0011] Compared with the prior art, the water and fertilizer proportioning control device provided by the application has the beneficial effects that:

[0012] The water for dissolving fertilizer is injected into the proportioning barrel, the fertilizer is loaded into the mesh box, and then the water for dissolving fertilizer is heated in the circulating pipe through the electric heater, and the heated water for dissolving fertilizer is flushed into the mesh box to pre-mix the fertilizer. The pre-mixed fertilizer is dissolved in water, passes through the mesh box, and is mixed by the stirrer in the proportioning barrel. The fertilizer water after dissolving the fertilizer can still be lifted by the circulating pump through the circulating pipe to pre-mix the fertilizer in the mesh box. The fertilizer water after the proportioning and mixing is finally discharged through the discharge pipe at the bottom of the proportioning barrel.

DETAILED DESCRIPTION ​​

[0021] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0022] As shown in Figures 1-4 An embodiment of the present application provides a water and fertilizer proportioning control device, which comprises a proportioning barrel 1, a water injection pipe 2 arranged at the top of the proportioning barrel 1, a discharge pipe arranged at the bottom of the proportioning barrel 1, and an agitator 3 arranged in the proportioning barrel 1 and driven by a motor 4. A feeding port 5 is arranged at one side of the top wall of the proportioning barrel 1, and a mesh box 6 for receiving fertilizer is fixed in the proportioning barrel 1 below the feeding port 5. A circulating pipe 7 is vertically arranged at the side end of the proportioning barrel 1, the bottom of the circulating pipe 7 is communicated with the proportioning barrel 1 through a liquid inlet pipe 8, a circulating pump 9 is arranged on the liquid inlet pipe 8, the top of the circulating pipe 7 is provided with a liquid outlet pipe 10 communicated with the mesh box 6, and an electric heater 11 is arranged in the circulating pipe 7. The electric heater 11 can adjust and set the temperature and heating time of water heating.

[0023] In use, a certain amount of water is injected into the proportioning barrel 1 through the water injection pipe 2, and a certain amount of fertilizer is added into the mesh box 6 from the feeding port 5, then the motor 4 and the circulating pump 9 are started. The circulating pump 9 pumps the water in the proportioning barrel 1 into the circulating pipe 7 through the liquid inlet pipe 8, and the water is heated by the electric heater 11.

[0024] The heated water is discharged into the mesh box 6 through the liquid outlet pipe 10 to pre-mix the fertilizer in the mesh box 6, the pre-mixed and dissolved fertilizer flows back to the proportioning barrel 1 through the mesh box 6, and the agitator 3 driven by the motor 4 further stirs and mixes the fertilizer. The water (or the fertilizer water after the fertilizer is dissolved) in the proportioning barrel 1 is continuously pumped to pre-mix the fertilizer in the mesh box 6, until the fertilizer in the mesh box 6 is completely dissolved into the proportioning barrel 1, then the circulating pump 9 is turned off, and the water and fertilizer after the proportioning and mixing are discharged from the discharge pipe.

[0025] In the embodiment, the water for dissolving fertilizer is injected into the proportioning barrel 1, the fertilizer is loaded into the mesh box 6, then the water for dissolving fertilizer is heated in the circulating pipe 7 by the electric heater 11, and the heated water for dissolving fertilizer is poured into the mesh box 6 to pre-mix the fertilizer. The pre-mixed fertilizer is dissolved into the water, passes through the mesh box 6, enters the proportioning barrel 1, and is stirred and mixed by the agitator 3, the fertilizer water after the fertilizer is dissolved can still be lifted by the circulating pump 9 from the circulating pipe 7 to pre-mix the fertilizer in the mesh box 6. The water and fertilizer after the proportioning and mixing are finally discharged from the discharge pipe at the bottom of the proportioning barrel 1.

[0026] By adjusting the heating temperature and time of the electric heater 11, the temperature of the water for dissolving the fertilizer can be controlled. Heating the water can accelerate the dissolution of the fertilizer, improve the dissolution efficiency and effect, and also improve the absorption efficiency of the plant to the fertilizer. By adding the fertilizer into the net box 6 for premixing and then stirring, the water-fertilizer ratio speed can be improved, and the net box 6 can filter out the difficult-to-dissolve caked fertilizer.

[0027] In a possible implementation, a fertilizer hopper 12 is arranged above the feeding port 5, and a discharger 13 is arranged at the bottom of the fertilizer hopper 12 and communicates with the feeding port 5.

[0028] The fertilizer is loaded into the fertilizer hopper 12, and during the process of stirring and mixing and heating the water, the fertilizer in the fertilizer hopper 12 is gradually added into the net box 6 for premixing through the discharger 13, so that the proportion of the fertilizer during premixing is too large to cause caking when dissolving water, and the premixing effect is further improved.

[0029] In a possible implementation, a gear box 14 for transmission is arranged at the top of the ratio barrel 1, the rotating shaft of the motor 4 is connected with the stirrer 3 in transmission through the gear box 14, and the rotating shaft of the motor 4 is fixed with the rotating shaft of the discharger 13 after penetrating through the gear box 14.

[0030] Using one motor 4 can drive the stirrer 3 and the discharger 13 to operate at the same time, which not only reduces the cost, but also enables the stirrer 3 and the discharger 13 to start and stop synchronously, so that the discharging and stirring are performed at the same time, which is convenient for operation.

[0031] In a possible implementation, a water inlet 15 for water injection is arranged at the lower end of the circulating pipe 7. A valve is arranged on the water inlet 15.

[0032] The liquid inlet pipe 8 is closed during water injection, and water is injected from the circulating pipe 7 to the ratio barrel 1 through the liquid outlet pipe 10 through the water inlet 15, so that the water can be heated by the electric heater 11 during the water injection stage. During operation, the fertilizer is only loaded into the net box 6, so that the water injection and premixing can be performed synchronously, the ratio time is further saved, and the efficiency is improved.

[0033] In a possible implementation, a filter screen cover 16 for filtering is arranged at one end of the liquid inlet pipe 8 in the ratio barrel 1.

[0034] The filter screen cover 16 can filter out larger impurity particles in the fertilizer water after the fertilizer is dissolved in the ratio barrel 1, so that the larger impurity particles are prevented from entering the circulating pump 9 to cause blockage.

[0035] In a possible implementation, the electric heater 11 is vertically inserted into the circulating pipe 7 from the upper end and detachably connected with the circulating pipe 7.

[0036] The electric heater 11 inserted into the circulation pipe 7 at the upper end is detachably connected, so as to be replaced or cleaned when damaged or the surface of the heating rod is scaled.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
