Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouse water and fertilizer drip irrigation equipment, and particularly relates to a water and fertilizer mixing device for drip irrigation in a solar greenhouse. Background Art

[0002] With the rapid popularization and development of the integrated water and fertilizer technology, the water and fertilizer management in solar greenhouses has shifted from traditional flood irrigation to drip irrigation technology. Drip irrigation technology uses plastic pipes to deliver water through orifices or drippers on the capillary tubes with a diameter of about 10 mm to the roots of crops for local irrigation. It is the most effective water-saving irrigation method in arid and water-deficient areas, and the water utilization rate can reach 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and at the same time, it can be combined with fertilization to increase the fertilizer efficiency by more than double. However, the existing agricultural drip irrigation water and fertilizer mixing devices have the problem of low water and fertilizer mixing efficiency. Some fertilizers with slow dissolution speed will be filtered out by the filter screen of the device in the form of granular residues, resulting in fertilizer waste. The fertilizer residues that are not filtered out are transported into the drip irrigation pipeline, which is extremely easy to block the drip irrigation head. In severe cases, the entire drip irrigation belt will be scrapped, bringing great inconvenience and losses to agricultural production. Therefore, it is necessary to design a water and fertilizer mixing device for drip irrigation in a solar greenhouse that can efficiently dissolve fertilizers with slow dissolution speed and avoid blockage of the drip irrigation head by fertilizer residues. Content of the Utility Model

[0003] Aiming at the above technical problems, the utility model provides a water and fertilizer mixing device for drip irrigation in a solar greenhouse that can efficiently dissolve fertilizers with slow dissolution speed and avoid blockage of the drip irrigation head by fertilizer residues, so as to solve the problem of blockage of the drip irrigation head by undissolved fertilizer residues.

[0004] To solve the above technical problems, the technical solution of the utility model is as follows: A water and fertilizer mixing device for drip irrigation in a solar greenhouse includes a water and fertilizer mixing tank and a support seat. A first stirring mechanism is arranged in the water and fertilizer mixing tank. An inlet pipe and a first feeding port are fixedly connected to the upper side of the water and fertilizer mixing tank. The bottom of the water and fertilizer mixing tank is fixedly connected to the drip irrigation belt water supply pipeline through a water outlet pipe, and a water outlet valve is installed on the water outlet pipe. The lower end of the water and fertilizer mixing tank is embedded and fixedly connected to the upper end of the support seat. A stirring barrel is fixedly connected to the inner top wall of the water and fertilizer mixing tank. A number of through holes are formed in the barrel wall of the stirring barrel. A second stirring mechanism is arranged in the stirring barrel. A second feeding port is communicated with the upper side of the stirring barrel. A vibration motor is fixedly connected to one side of the support seat. An installation plate is fixedly connected to the bottom of the support seat. A number of springs are fixedly connected to the bottom of the installation plate, and the bottom of the springs is fixedly connected to a base.

[0005] Further, the first stirring mechanism includes a first stirring motor and a first stirring paddle. The first stirring motor is fixedly connected to the top of the water-fertilizer mixing tank. The output end of the first stirring motor penetrates through the water-fertilizer mixing tank and is fixedly connected to the upper end of the first stirring paddle.

[0006] Further, the second stirring mechanism includes a second stirring motor and a second stirring paddle. The second stirring motor is fixedly connected to the top of the water-fertilizer mixing tank. The output end of the second stirring motor penetrates through the water-fertilizer mixing tank and is fixedly connected to the upper end of the second stirring paddle.

[0007] Further, cover plates are hinged on both the first feeding port and the second feeding port.

[0008] Further, a filter screen is fixedly connected to the inner wall of the stirring barrel.

[0009] The present utility model has the following advantages compared with the prior art:

[0010] 1. By arranging a stirring barrel in the water-fertilizer mixing tank, the present utility model can separately stir and dissolve fertilizers with slow dissolution rates. The dissolved fertilizer solution enters the water-fertilizer mixing tank through the through holes, avoiding the transportation of undissolved fertilizer residues into the drip irrigation pipeline and causing blockage of the drip irrigation heads. By arranging a vibration motor, a mounting plate and a spring on the support base connected to the lower part of the water-fertilizer mixing tank, the water-fertilizer mixing tank can be vibrated and shaken while stirring and mixing the water and fertilizer in the water-fertilizer mixing tank, accelerating the dissolution of the fertilizer and improving the efficiency of water-fertilizer mixing.

[0011] 2. By hinging cover plates on the two feeding ports, the present utility model can prevent impurities from entering the device through the feeding ports and avoid pollution of the water and fertilizer. By arranging a filter screen in the stirring barrel, it can prevent incompletely dissolved fertilizer particles from passing through the through holes and entering the water-fertilizer mixing tank, avoiding blockage of the drip irrigation heads.

[0015] The present utility model will be further described below in conjunction with the accompanying drawings.

[0016] As Figure 1 , Figure 2 shown, a water and fertilizer mixing device for drip irrigation in a solar greenhouse includes a water and fertilizer mixing tank 1 and a support base 2. A first stirring mechanism 3 is arranged inside the water and fertilizer mixing tank 1. An inlet pipe 4 is fixedly connected to the upper side of the water and fertilizer mixing tank 1. An inlet valve is installed on the inlet pipe 4. A first feeding port 5 is opened at the top of the water and fertilizer mixing tank 1. A water outlet pipe 6 communicates with the bottom of the water and fertilizer mixing tank 1 and is fixedly connected to a drip irrigation belt water supply pipe 7. An outlet valve is installed on the water outlet pipe 6. The lower end of the water and fertilizer mixing tank 1 is embedded and fixedly connected to the upper end of the support base 2. The water outlet pipe 6 penetrates and extends outside the support base 2. A stirring barrel 8 is arranged inside the water and fertilizer mixing tank 1. A plurality of through holes are opened on the barrel wall of the stirring barrel 8. The fertilizer solution in the stirring barrel 8 can enter the water and fertilizer mixing tank 1 through the through holes. The upper end of the stirring barrel 8 is fixedly connected to the inner wall of the top of the water and fertilizer mixing tank 1. A second stirring mechanism 9 is arranged inside the stirring barrel 8. A second feeding port 10 communicates with the upper side of the stirring barrel 8. The second feeding port 10 extends to the outside of the water and fertilizer mixing tank 1. A vibration motor 11 is fixedly connected to one side of the support base 2. A mounting plate 12 is fixedly connected to the bottom of the support base 2. The cross-sectional sizes of the support base 2 and the mounting plate 12 are the same. A plurality of springs 13 are fixedly connected to the bottom of the mounting plate 12. The bottom of the springs 13 is fixedly connected to a base 14.

[0017] In order to stir and dissolve the fertilizer in the water and fertilizer mixing tank 1 and accelerate the mixing of water and fertilizer, the first stirring mechanism 3 includes a first stirring motor 31 and a first stirring paddle 32. The first stirring motor 31 is fixedly connected to the top of the water and fertilizer mixing tank 1. The output end of the first stirring motor 31 penetrates the water and fertilizer mixing tank 1 and is fixedly connected to the upper end of the first stirring paddle 32.

[0018] In order to stir and dissolve the fertilizer in the stirring barrel 8, the dissolved fertilizer enters the water and fertilizer mixing tank 1 through the through holes and accelerate the mixing of water and fertilizer, the second stirring mechanism 9 includes a second stirring motor 91 and a second stirring paddle 92. The second stirring motor 91 is fixedly connected to the top of the water and fertilizer mixing tank 1. The output end of the second stirring motor 91 penetrates the water and fertilizer mixing tank 1 and is fixedly connected to the upper end of the second stirring paddle 92.

[0019] In order to prevent sundries from entering the device through the feeding port when no fertilizer is added, covers are hinged on both the first feeding port 5 and the second feeding port 10. When fertilizer needs to be added, lift the cover. After adding, close the cover again.

[0020] To prevent incompletely dissolved fertilizer particles from entering the water-fertilizer mixing tank 1 through the through-holes on the barrel wall of the stirring barrel 8, a filter screen is fixedly connected to the inner wall of the stirring barrel 8. The pore diameter of the filter screen is smaller than the pore diameter of the through-holes opened on the barrel wall of the stirring barrel. In this embodiment, the filter screen uses a 300-mesh stainless steel filter screen with a pore diameter of 0.05 mm.

[0021] The specific working process of the present utility model is as follows:

[0022] Open the water inlet valve on the water inlet pipe 4 to inject water into the water-fertilizer mixing tank 1. After reaching the water level, close the water inlet valve. Start the first stirring motor 31, the second stirring motor 91, and the vibration motor 11 respectively. Lift the cover plate of the first feeding port 5 and add the fertilizer that is easily soluble in water into the water-fertilizer mixing tank 1, and continuously dissolve it under the agitation of the first stirring paddle 32. Lift the cover plate of the second feeding port 10 and add the fertilizer with a slow dissolution rate into the stirring barrel 8, and continuously dissolve it under the agitation of the second stirring paddle 92. The dissolved solution passes through the through-holes on the barrel wall of the stirring barrel 8 and enters the water-fertilizer mixing tank 1. The incompletely dissolved fertilizer residues are blocked by the filter screen arranged in the stirring barrel 8. The vibration motor 11 drives the support seat 2 to vibrate, and the spring 13 absorbs and buffers the vibration. The water-fertilizer mixing tank 1 vibrates along with the support seat 2. The water and fertilizer inside the water-fertilizer mixing tank 1 are continuously mixed evenly under the dual action of stirring and vibration shaking. After the fertilizer is completely dissolved, open the water outlet valve on the water outlet pipe 6, and introduce the evenly mixed water-fertilizer solution into the drip irrigation tape water supply pipe 7, and transport it to the drip irrigation pipe network through a liquid pump for drip irrigation of the crops in the greenhouse.
