Description

Technical Field

[0001] The utility model relates to the technical field of water-soluble fertilizer fertilizing devices, in particular to an anti-drip multi-hole fertilizing device. Background Art

[0002] Water Soluble Fertilizer (WSF) is a multi-component compound fertilizer that can be completely soluble in water. It can dissolve quickly in water and is more easily absorbed by crops. It also has a relatively high absorption and utilization rate. It can also achieve water-fertilizer integration, saving water, fertilizer, and labor. Compared with traditional superphosphate, granulated compound fertilizers and other varieties, water-soluble fertilizers have obvious advantages. Its main features are small dosage, easy use, low cost, fast crop absorption, and extremely high nutrient utilization rate. In this way, people can completely design formulas according to the nutritional requirements of crop growth. Scientific formulas will not cause waste of fertilizers, making their fertilizer utilization rate almost 2-3 times that of conventional compound chemical fertilizers.

[0003] The conventional water-soluble fertilizer fertilization method is to spray it on the soil surface near the plant root system, allowing it to enter the vicinity of the crop root from the land surface by infiltration, so that the crop can absorb it, and its fertilization efficiency is low. Therefore, a fertilization method of directly pouring water-soluble fertilizer into the root of the plant by inserting a cutting tube into the soil has emerged. For example, a Chinese patent with application number CN2016105267304 discloses a field multi-hole water-soluble fertilizer underground fertilizer applicator, including a water-soluble fertilizer box and a fertilizer applicator arranged on a frame, and the water-soluble fertilizer box is connected to the fertilizer applicator through a fertilizer guide pipe; the fertilizer applicator includes a drill rod fixing frame, and a drill rod fixed on the drill rod fixing frame, the drill rod has openings at both ends and a hollow in the middle, and its upper end opening is connected to the fertilizer guide pipe; the drill rod fixing frame includes a pressure rod and a connecting rod, and the pressure rod is connected to the connecting rod by a movable shaft, and the connecting rod is connected to the drill rod by a movable shaft. It can directly apply water-soluble fertilizer into the land through the drill rod to improve the utilization efficiency of water-soluble fertilizer.

[0004] However, the current water-soluble fertilizer applicator with a plug-in structure uses multiple cutting tubes to be connected to a fertilizer transport tube at the same time, that is, the insides of each cutting tube are interconnected. After one fertilization is completed, due to slight differences in the diameters and inner wall roughness of different cutting tubes, air will flow back into some cutting tubes, causing the residual water-soluble fertilizer in other cutting tubes to leak. This will lead to a waste of water-soluble fertilizer and dirty clothes and other equipment. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, the embodiment of the utility model proposes an anti-drip multi-hole fertilization device, including a water-soluble fertilizer storage tank 1 and a cutting fertilizer applicator. The water-soluble fertilizer storage tank 1 is provided with a shoulder strap 11 for the user to carry it, and a cart structure can also be used to carry the water-soluble fertilizer storage tank 1, which can be adjusted according to its weight.

[0025] The cutting fertilizer applicator comprises a bracket, a feeding assembly 4 and a plurality of cutting tubes 5 connected in sequence, the feeding assembly 4 is connected to the water-soluble fertilizer storage tank 1 through a hose 2, the cutting tubes 5 are arranged in parallel on one side of the feeding assembly 4, and are connected to the inside of the feeding assembly 4, the bracket is fixed on the feeding assembly 4 on the side opposite to the cutting tubes 5, and is parallel to the cutting tubes 5. This embodiment is preferably provided with four cutting tubes 5. Preferably, the bottom of the cutting tube 5 is pointed and contracted, so that it is easier to insert into the soil.

[0026] Specifically, the bracket includes a support rod 3 parallel to the cutting tube 5, one end of the support rod 3 is fixedly connected to the housing, and the other end is provided with a handle 31. Its length corresponds to half to two-thirds of the height of a common human body, so that the user can easily insert the cutting tube 5 into the soil through the handle 31.

[0027] like Figure 2 As shown, in this embodiment, the feeding assembly 4 includes a hollow shell, and in this embodiment, the shell is a flat square structure. A feed port 41 is provided on the top of the shell, and a high-pressure water pump is also provided on the water-soluble fertilizer storage tank 1. The discharge port 42 of the high-pressure water pump is connected to the hose 2, and then connected to the feed port 41 on the shell by the hose 2. Several discharge ports 42 corresponding to the cutting tubes 5 are arranged in parallel at the bottom, and several mutually parallel partitions 43 are also provided in the shell. The partition plates 43 divide the internal space of the shell into multiple discharge channels 44. The multiple discharge channels 44 are connected at one end close to the feed port 41, and the other ends correspond to the discharge ports 42 respectively. A one-way valve 6 is also provided in the discharge channel 44, and the one-way valves 6 in all the discharge channels 44 work synchronously. Since four cutting tubes 5 are provided in this embodiment, four discharge channels 44 are separated.

[0028] Further, the one-way valve 6 includes a gasket 61 arranged on the inner wall of the discharge channel 44, the middle part of the gasket 61 protrudes inward to form a circular contraction structure, and also includes a valve body 62 arranged on the side close to the discharge port 42 relative to the gasket 61, the valve body 62 will not close the discharge channel 44 where it is located, and the side of the valve body 62 close to the gasket 61 is a curved surface structure, so that the valve body 62 and the gasket 61 are in close contact. The discharge channel 44 of the gasket 61 is completely closed. In this embodiment, the valve body 62 is a spherical structure. The end of the valve body 62 away from the gasket 61 is provided with an elastic member, which applies an elastic force to the valve body 62 toward the side of the gasket 61. Further, a connecting rod 7 is also provided inside the shell, and the connecting rod 7 is perpendicular to the direction of the discharge channel 44, so as to sequentially penetrate the partition plate 43 and extend to the inside of each discharge channel 44, and the partition plate 43 is located on the side of the valve body 62 away from the gasket 61 and is fixedly connected to the valve body 62, and the elastic member is provided at the end of the connecting rod 7 away from the valve body 62. It should be noted that the partition plate 43 is also provided with a sliding groove, and the sliding groove is for the connecting rod 7 to pass through when moving along the partition plate 43. In coordination therewith, the shell is also provided with a mounting groove 45 parallel to the discharge channel 44, and the mounting groove 45 is also divided by the partition plate 43, one end of the mounting groove 45 is connected to the inner area of ​​the shell, and the other end is closed, and the elastic member includes a spring 8 arranged inside the mounting groove 45, one end of the spring 8 is fixed inside the mounting groove 45, and the other end is connected to the connecting rod 7. In this embodiment, the mounting groove 45 is located in the middle of the four discharge channels 44, and the discharge channels 44 are separated in pairs, so that the spring 8 is exactly in the center position of the connecting rod 7, so that the connecting rod 7 is subjected to more uniform force.

[0029] When the water-soluble fertilizer storage tank 1 pumps high-pressure water-soluble fertilizer into the shell through the high-pressure water pump, pressure is applied to the valve body 62 in each discharge channel 44. The pressure applied to the four valve bodies 62 simultaneously drives the connecting rod 7 to move toward the side of the discharge port 42 against the elastic force applied by the spring 8. The valve body 62 is separated from the gasket 61, and the fertilizer flows into each cutting tube 5 from the discharge channel 44 in turn to complete the fertilization. When the fertilization is completed, the high-pressure water pump stops working and prevents the material inside the water-soluble fertilizer storage tank 1 from continuing to flow out. Then the valve body 62 and the connecting rod 7 are no longer subjected to pressure, that is, they are reset under the elastic force of the spring 8, and the valve body 62 continues to contact the gasket 61 to achieve the sealing of the discharge channel 44. At this time, each discharge channel 44 and the cutting rod connected thereto are in an independent sealing state, and there will be no air backflow and dripping.

[0030] like Figure 3As shown, in the preferred solution, a slide groove 9 is further provided on the inner wall of the outer shell of the two outermost discharge channels 44, and the slide groove 9 corresponds to the direction of the discharge channel 44. Slide blocks 71 are respectively provided at both ends of the connecting rod 7, and the slide blocks 71 are embedded in the slide groove 9 and can only slide along the direction of the slide groove 9. In this way, the connecting rod 7 can only move along the direction of the discharge channel 44, and will not deflect, resulting in the problem of inconsistent opening degree of the valve body 62.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
