Abstract

The utility model relates to a knapsack agricultural fertilizer applicator which can directly apply fertilizer to the most proper position of soil under the root of crops, and the fertilization application mode does not damage the roots of the crops. The knapsack agricultural fertilizer applicator comprises a compression bar which is provided with a handle at the upper end and fixed with a sleeve at the lower end; the sleeve is positioned in an inner casing; the middle part of a connecting rod at the lower part of the sleeve is fixed with a plunger piston, and the lower end of the connecting rod is provided with an insertion recessed head; the length of the inner casing, fixed in a shell pipe barrel, is shorter than that of the shell pipe barrel, on which a fertilizer inlet is arranged, the shell pipe barrel and the inner casing are provided with fertilizer inlets which correspond to each other and connected with a knapsack fertilizer bag by a hose; and the lower end of the shell pipe barrel is fixed with a plate with a fertilizer outlet. After adopting the knapsack agricultural fertilizer applicator, fertilizer application can be conveniently carried out on the crops, the time and manpower are saved, the raw materials are saved and the environment is protected.

Description

The backpack farm fertilizer applicator

Technical field

The utility model relates to a kind of mechanical field, particularly relate to a kind of backpack farm fertilizer applicator.

Background technology

Owing to be subjected to the restriction of landform, the fertilising of crops can't color mechanized application mode and during equipment, and the fertilising instrument will think better of, and how reach optimum efficiency.Traditional plane is cheated fertilising or is loose and spill the disconnected blade of the easy magnetic of chemical fertilizer, damage root system and mulch film, the output of minimizing crop, and labour intensity is big, and the fertilizer waste is serious, and easily causes environmental pollution, and fertilization effect is relatively poor.Through utility model people market investigation with consult related data, following several similar techniques is arranged at present: (1) liquid fertilization gun, it at first will with institute to fertilize water dilute, speed is slow, increased cost of labor, its gun barrel of the liquid fertilizer after the dilution will being packed into secondly, the splendid attire capacity is little, as easy as rolling off a log causing loose to be leaked, produce waste, and in the fertilising process, owing to be liquid fertilization, earth is easy to stop up bullet hole, and influence is fertilising normally.(2) digging type particle fertilizer applicator.It has increased fertilising person's labour intensity, the easy damaged crop root, and fertilising is attempted being difficult to grasp, and influences the absorption of crops.(3) injection type fertilizer applicator, but because design is unreasonable, not backpack, cause staff's splendid attire chemical fertilizer back and forth, lose time and manpower.

The utility model content

Deficiency at above-mentioned prior art existence; the utility model provides a kind of backpack farm fertilizer applicator; it can directly apply chemical fertilizer the most appropriate position of the following soil of crop root part; this fertilization mode does not damage the crops root system, thereby helps improving grain yield and environmental protection and save time and manpower.

The utility model provides a kind of backpack farm fertilizer applicator, and it comprises that the upper end is fixed with handle, and sleeved depression bar is fixed in the lower end; Sleeve is arranged in inner sleeve, and the connecting rod middle part of the bottom of sleeve is fixed with plunger, and the lower end of connecting rod is equipped with inserts the cave-head; The length that is fixed on the inner sleeve in the shell socket is less than the shell socket, has on the shell socket on into fertile mouthful and shell socket, the inner sleeve the corresponding Fei Kou that advances is arranged, and describedly advances fertile mouthful and connects by flexible pipe with the backpack bag with fertilizer; Shell socket lower end is fixed with the plate of taking fertile hole out of.

Described bar is installed in lower cartridge by screw thread, and slotting cave-head is installed in the connecting rod lower end by screw thread.

Described shell socket lower end is fixed with breast boards, and shell socket outside is hinged with pedal-rod, and group plate of dialling on the native bar that the pedal-rod bottom is fixing is relative with breast boards, between pedal-rod and the shell socket extension spring is arranged.

Described depression bar is provided with projection.

After adopting the utility model, crops are applied fertilizer very easily, save time and manpower; Conservation, the protection environment.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described further

Fig. 1 is the schematic diagram of the structure of the utility model when depression bar is mentioned;

Fig. 2 is that the utility model is depressed at depression bar, the structural representation when promptly inserting the cave;

Fig. 3 is the utility model backpack bag with fertilizer schematic diagram.

Embodiment

This practicality comprises that newly with the novel backpack farm fertilizer applicator that provides the upper end is fixed with handle 1, and sleeved depression bar 2 is fixed in the lower end; Sleeve is arranged in inner sleeve 5, and the connecting rod middle part of the bottom of sleeve 4 is fixed with plunger 15, and the lower end of connecting rod 16 is equipped with inserts cave-head 8; The length that is fixed on the inner sleeve 5 in the shell socket 6 is less than shell socket 6, have into fertile mouthful 7 on the shell socket 6 and shell socket 6, inner sleeve 5 on the corresponding Fei Kou that advances is arranged, describedly advance fertile mouthful 7 and connect by flexible pipe with backpack bag with fertilizer 17; Shell socket 6 lower ends are fixed with the plate 9 of taking fertile hole out of.

Described connecting rod 16 is installed in sleeve 4 bottoms by screw thread, inserts cave-head 8 and is installed in connecting rod 16 lower ends by screw thread.The backpack fertilizer applicator of this structure can be by the bar 16 that is rotationally connected, and changes the distance between plunger 15 and the sleeve 4, promptly changes the size of the storage fertilizer chamber volume that is made of relative face of plunger 15, sleeve 4 and inner sleeve 5 inwalls, thereby adjusts each fertilizing amount.Insert cave-head 8 by rotating, can change the overhang of inserting cave-head 8, promptly change and insert the degree of depth that the cave-head inserts soil, adjust fertilization depth.

Be fixed with breast boards 10 in described shell socket 6 lower ends, shell socket 6 outsides are hinged with pedal-rod 13, and group plate of dialling on the native bar 12 11 that pedal-rod 13 bottoms are fixing is relative with breast boards 10, between pedal-rod 13 and the shell socket 6 extension spring 14 is arranged.The artificially applying fertilizer device of this structure, after fertilizer fell into fertile cave, the bar that can treadle made and dials plate near breast boards, under both actings in conjunction, finishes earthing work, with the efficiency of further raising fertilising.

On the depression bar 2 projection 3 can be arranged, the location when depressing with realization depression bar 2.
