Description

Single-double-head adjustable fertilizing gun

Technical Field

The utility model belongs to the technical field of irrigation equipment, concretely relates to fertilization rifle with adjustable single double-end.

Background

The fertilizer application technology of the fertilizer application gun is a common fertilizer application mode in agricultural production at present, the fertilizer application gun directly injects liquid fertilizer required by plants into the rhizosphere of the plants to achieve centralized supply, precise supplement, balanced nutrient supply and implementation of a quantitative agricultural cultivation mode, and the innovation of the fertilizer application gun is a novel scientific fertilizer application technology which is researched by plant nutriologists and soil fertilizer specialists according to the growth state of the plants and the requirement rule of nutrients, the combination of soil fertility foundation, plant growth environment and other factors. The popularization and application of the technology and the guarantee of related supporting facilities are combined with the scientificity of formula fertilization, so that the popularization and application of the technology are deep in civilian mind, and the effects of rapidness, good and economic performance, source opening, throttling, consumption reduction and income increase are achieved.

Practice proves that the fertilizer applying gun can be widely applied to fertilization of crops such as orchards, greenhouse vegetables, watermelons and the like, not only reduces the production intensity and investment cost of farmers, but also greatly improves the utilization rate of chemical fertilizers, improves the yield and the quality, promotes the robustness of the growth situation of the crops, and has obvious effects of increasing the yield and increasing the income. In addition, the fertilizer application gun can also solve the traditional cultivation mode that water and fertilizer application cannot be carried out when fruits and vegetables in the greenhouse are low in temperature, poor in illumination and high in humidity in winter, so that the problems that the crops grow slowly due to lack of elements and lack of nutrients, are susceptible to diseases and low in yield are solved, vegetable farmers can apply fertilizer and supplement energy at the utmost without increasing the humidity in the greenhouse, the occurrence of diseases is greatly degraded, the investment of pesticides can be reduced, the pesticide damage cannot be caused, the pesticide residue is reduced, producers can eat vegetables with high yield and high yield in winter and can safely and reassurance consumers, and the technical requirement standard of national green organic agriculture production is met.

In order to improve the fertilization efficiency, the front end of part fertilization rifle is equipped with two or even three rifle heads, but these rifle heads all are fixed in on the barral of a gun, can only realize that many rifle heads fertilize simultaneously, can't carry out single rifle head fertilization, can't use in the scene that needs the haplopore fertilization, have reduced the range of application of fertilization rifle. Simultaneously, because the rifle head is fixed, the fertilization interval of adjacent fertilization rifle is not convenient for adjust.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figure 1, the single-double-head adjustable fertilizing gun comprises a handle 1, a valve 3, a flow meter 5 and a gun barrel 7 which are connected in sequence from top to bottom. The inside cavity that is of handle 1, the upper end of cavity are equipped with and are used for connecting joint 2, the lower extreme connection valve 3 of defeated fertilizer pipe, are connected with the handle 4 that is used for opening and closing valve 3 on the valve 3, and for the convenience of gripping, handle 4 is located handle 1 under, still is connected with display 6 on the flowmeter 5, can show the liquid volume of flowing through flowmeter 5 in real time.

The upper portion of barrel 7 is connected with the application of force ring 8 that is used for holding the application of force, and application of force ring 8 includes outer loop and the inner ring of welded fastening as an organic whole, and the inner ring cover connects on barrel 7, and inner ring one side still is connected with first locking screw. The force applying ring 8 can be moved up and down by unscrewing the first locking screw rod, and the force applying ring 8 can be fixed by screwing the first locking screw rod.

The lower extreme of barrel 7 can be dismantled and be connected with first rifle head 12, and the lower part of barrel 7 still is connected with the fixed frid 9 of rectangle that the level outwards stretched out, and swing joint has the slider 10 of rectangle frame form on the fixed frid 9, and the through-hole has been seted up at the top of slider 10, is connected with second locking screw 11 in the through-hole. The lower part of the slide block 10 is connected with a vertical second gun head 13, and the lower ends of the first gun head 12 and the second gun head 13 are flush. The diameter of the first gun head 12 is equal to that of the second gun head 13 and is smaller than that of the gun barrel 7, the first gun head 12 is communicated with the gun barrel 7, a fertilizer conveying branch pipe is connected between the second gun head 13 and the gun barrel 7, and a stop valve is connected to the fertilizer conveying branch pipe. The lower ends of the first gun head 12 and the second gun head 13 are conical, two annular waist-tightening grooves are further formed in the conical positions, and a plurality of fertilizer outlet holes are formed in the waist-tightening grooves. Further, the barrel 7, the first tip 12, and the second tip 13 are made of stainless steel.

The working principle of the utility model is as follows:

when the double-hole fertilization is carried out, the connector 2 is connected to the fertilizer conveying pipe, then the first locking screw rod is unscrewed according to the height and the arm length of an operator, and the position of the force applying ring 8 is adjusted, so that the force applying ring is convenient to operate and apply force. And loosening the second locking screw rod 11, shifting the slide block 10 to move the position of the second gun head 13, adjusting the distance between the first gun head 12 and the second gun head 13, and screwing the second locking screw rod 11 again after adjusting to the required distance.

During fertilization, an operator holds the handle 1 with the right hand and holds the upper force application ring 8 with the left hand, the gun heads of the fertilization guns are vertically aligned to positions needing fertilization, two hands apply force simultaneously, the two gun heads are completely inserted into soil, and when soil hardening occurs, the fixed groove plates 9 can be stepped by feet to assist in force application. Then the handle 4 is pinched by the right hand, the valve 3 is opened, the fertilizer liquid passes through the handle 4, the gun barrel 7 and the gun head, and finally is discharged from the fertilizer outlet hole and permeates into the soil, the indication number on the flowmeter 5 is observed, after the required fertilizer application amount is reached, the handle 4 is loosened, the valve 3 is closed, then the fertilizer gun is pulled out from the soil, and the next place is selected for continuous fertilizer application. The fertilizer outlet hole is arranged in the waist-contracting groove, and when the gun head is inserted into soil, the waist-contracting groove and the soil form a certain hole to prevent the fertilizer outlet hole from being blocked.

When single-hole fertilization is carried out, the second fixing screw is unscrewed, the second gun head 13 is taken down from the fixing groove plate 9, then the orientation of the second gun head 13 is turned upwards, the second gun head 13 is remounted to the fixing groove plate 9, and the second valve 3 is closed.
