Description

Technical Field

[0001] This utility model relates to the technical field of water and fertilizer mixing equipment, specifically a non-powered water and fertilizer integrated mixing machine. Background Technology

[0002] The integrated water and fertilizer system is a new, highly efficient, water- and fertilizer-saving agricultural irrigation technology. This technology is significant in improving water resource utilization and promoting cost reduction and efficiency in agriculture. By improving the systematization and precision of agricultural irrigation and fertilization, the integrated water and fertilizer system reduces the burden on energy supply and environmental pollution, and has become a core direction for modern agricultural development. Currently, most integrated water and fertilizer systems use motor-driven impellers for mixing. Traditional mixing equipment relies on electricity or fuel power, resulting in high energy consumption, high maintenance costs, and poor adaptability (e.g., in remote areas with power shortages).

[0003] Patent publication number CN201398353Y discloses a fertilizer tank for drip irrigation, specifically including a stirrer installed inside the tank, with the water inlet pipe opening facing the impeller on the stirrer, so that the stirrer rotates and mixes continuously under the action of water flow. However, it has problems such as poor mixing effect and inability to achieve quantitative mixing of the required fertilizer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a non-powered water and fertilizer mixing machine that can achieve water and fertilizer mixing without power or mechanical movement, save energy, and achieve good mixing effect, which is in line with the concept of green agriculture. It can realize the quantitative mixing of the required fertilizers. It has a simple structure, low maintenance cost, is easy to clean, and has strong adaptability and stable operation. It can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-powered mixing water and fertilizer integrated machine, comprising a storage hopper above a mixing drum, the mixing drum being placed horizontally, a fertilizer inlet at the top of the mixing drum; a water inlet at the bottom of one side of the mixing drum, connected to a water supply pipe, and a water and fertilizer outlet pipe at the bottom of the other side of the mixing drum; spiral guide vanes arranged along its axial direction inside the mixing drum; the storage hopper being mounted above the mixing drum via a supporting steel frame; the mixing drum can utilize the kinetic energy of the fluid flowing along the spiral guide vanes to achieve turbulent mixing of water and fertilizer inside.

[0006] Furthermore, the spiral guide vane includes at least two spiral blades spaced apart from each other, the spiral directions of the spiral blades are the same, and adjacent spiral blades are staggered in the circumferential direction, and the outer diameter of the spiral blades is adapted to the inner diameter of the mixing cylinder.

[0007] Furthermore, the storage hopper includes a truncated cone funnel, and a first turbine flange butterfly valve is provided at the discharge port of the truncated cone funnel; the truncated cone funnel is fixedly mounted on a supporting steel frame.

[0008] Furthermore, the supporting steel frame is equipped with a metering device, which includes a support frame, the support frame being fixedly connected to the supporting steel frame, and a conical funnel fixedly mounted on the support frame. The conical funnel is located between the storage hopper and the mixing cylinder, and the discharge port of the conical funnel is equipped with a second turbine flange butterfly valve.

[0009] Furthermore, the inlet end of the water supply pipe is connected to a filter, and the filter is a centrifugal mesh filter.

[0010] Furthermore, the mixing drum has support legs on both sides of its bottom end, and the top of each support leg has an arc-shaped support plate that fits against the outer wall of the bottom end of the mixing drum.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This non-powered water and fertilizer integrated machine, through the spiral guide vanes provided in the mixing drum, causes the water flowing into the mixing drum to impact the fertilizer inside and create turbulence along the spiral vanes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-4 This utility model provides a technical solution: a non-powered mixing water and fertilizer integrated machine, including a storage hopper 4 above a mixing drum 2, the mixing drum 2 being placed horizontally, a fertilizer inlet 21 at the top of the mixing drum 2; a water inlet 22 at the bottom of one side of the mixing drum 2, the water inlet 22 being connected to a water supply pipe 6, and a water and fertilizer outlet pipe 23 at the bottom of the other side of the mixing drum 2; and spiral guide vanes 3 arranged inside the mixing drum 2 along its axial direction.

[0022] The spiral guide vane 3 includes at least two spiral vanes 31 spaced apart from each other. The spiral directions of the spiral vanes 31 are the same, and adjacent spiral vanes 31 are staggered in the circumferential direction. The outer diameter of the spiral vane 31 is adapted to the inner diameter of the mixing cylinder 2. The mixing cylinder 2 can use the kinetic energy of the fluid flowing along the spiral guide vane 3 to make the water and fertilizer inside it turbulently mixed. In this embodiment, there are two spiral vanes 31, and the two spiral vanes 31 are staggered by 180° in the circumferential direction.

[0023] Please refer to the following: Figure 5 The storage hopper 4 is mounted above the mixing cylinder 2 via a supporting steel frame 1. The storage hopper 4 includes a truncated cone funnel 41, and a first turbine flange butterfly valve 42 is provided at the discharge port of the truncated cone funnel 41. The truncated cone funnel 41 is fixedly mounted on the supporting steel frame 1.

[0024] Please refer to the following: Figure 6The supporting steel frame 1 is equipped with a metering device 5, which includes a support frame 53. The support frame 53 is fixedly connected to the supporting steel frame 1. A conical funnel 51 is fixedly mounted on the support frame 53. The conical funnel 51 is located between the storage hopper 4 and the mixing cylinder 2. The discharge port of the conical funnel 51 is equipped with a second turbine flange butterfly valve 52. In this embodiment, the supporting steel frame 1 is also equipped with a controller for controlling the opening and closing of the first turbine flange butterfly valve 42 and the second turbine flange butterfly valve 52. The controller can control the opening time of the first turbine flange butterfly valve 42. The conical funnel 51 is a metering hopper of a specific capacity. Usually, the capacity of one conical funnel 51 is used as the unit of measurement.

[0025] Please refer to the following: Figure 7 The water inlet end of the water supply pipe 6 is connected to a filter 7, and the filter 7 is a centrifugal mesh filter.

[0026] In use: The water inlet of filter 7 is connected to an external water supply device through a pipe, and fertilizer is poured into the truncated cone funnel 41 of storage hopper 4;

[0027] First, open the first turbine flange butterfly valve 42 to allow fertilizer in the conical funnel 41 to flow into the conical funnel 51. The amount of fertilizer flowing into the conical funnel 51 is measured according to the opening time of the first turbine flange butterfly valve 42 (generally, the amount of fertilizer flowing into the conical funnel 51 should reach its specific capacity). After the required amount of fertilizer has flowed into the conical funnel 51, close the first turbine flange butterfly valve 42 and open the second turbine flange butterfly valve 52, allowing all the fertilizer in the conical funnel 51 to be transferred into the mixing drum 2. Then, a special water supply is supplied to the filter 7 through an external water supply device. A fixed volume of water, after being filtered by filter 7, flows into the mixing drum 2 through water pipe 6. The water flow into the mixing drum 2 impacts the fertilizer inside and flows along the spiral blades 31. The spiral blades 31 all have the same spiral direction, and adjacent spiral blades 31 are staggered in the circumferential direction, which transforms the linear motion of the water flow into multi-directional turbulence. The fluid's own kinetic energy generates shearing, eddies, and backflow, driving the fertilizer to mix and dissolve in a turbulent manner, achieving water-fertilizer mixing without mechanical motion. Finally, the mixed water and fertilizer are discharged by opening the water-fertilizer outlet pipe 23.

[0028] Furthermore, the mixing cylinder 2 has support legs 24 on both sides of its bottom end, and the top of each support leg 24 has an arc-shaped support plate 25 that fits against the outer wall of the bottom end of the mixing cylinder 2. The mixing cylinder 2 is placed stably.

[0029] The non-powered water-fertilizer mixing machine disclosed in this embodiment uses spiral guide vanes 3 inside the mixing drum 2 to cause the water flowing into the mixing drum 2 to impact the fertilizer inside and create turbulence along the spiral vanes 31. The fluid's own kinetic energy generates shearing, eddies, and backflow, driving the fertilizer to mix and dissolve in a turbulent manner. This achieves water-fertilizer mixing without power or mechanical movement, saving energy, and providing good mixing effect, which is in line with the concept of green agriculture. The first turbine flange butterfly valve 42 and the metering device 5 can achieve quantitative mixing of the required fertilizer (i.e., quantitative fertilizer input). The required quantitative fertilizer is added into the mixing drum 2 at once for mixing and dissolution, reducing fluctuations in water-fertilizer concentration. The structure is simple, the maintenance cost is low, it is easy to clean, and the equipment is highly adaptable and operates stably.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
