Abstract

The utility model relates to a high pressure sprayer for worm killing, weed removing fertilization and sterilization in fields such as agriculture, forestry, environmental hygiene; the purpose is to overcome the disadvantage of the above background technology with improvement for backpacked sprayer which features with large pressure, high lift, simple structure, longer durability and less failure. The technology scheme is : a backpacked high pressure sprayer including a cylinder, water compression elements and a compression tank; a band rests on the cylinder and the water compression elements is composed with a cylinder body, a piston moving in the cylinder and a compression rod to drive the piston; the piston includes a piston rod and a piston block fixed on the rod top, and the outer perimeter of the piston block is less slightly than the inner diameter of the cylinder and a positioning slot encircling the whole outer perimeter, a seal ring stays in each positioning slot. The cylinder is made of stainless steel.

Description

The Backpack type high-pressure sprayer
Technical field
The utility model relates to a kind of non-power agrisilviculture apparatus, specifically is the high-pressure sprayer that agricultural, forestry, environmental sanitation field are used for operations such as deinsectization, weeding, fertilising, sterilization.
Background technology
Existing is the knapsack sprayer of power with the manpower, because structural design exists many defectives.Especially the structure of its setting-out parts is to fix two reverse superimposed leather cups on the top of piston rod, and motion setting-out in the plastics inflator quite feel painstaking when not only the operator uses, and pressure is little, and lift is not high.Usually straight spray lift has only 2-3 rice, and horizontal spray lift has only 5-6 rice.Owing to the fruit tree (as apple tree, Chinese walnut) 4-5 rice height is arranged all, thereby when the fertilising of spray medicine, the operator can only climb to tree and go up operation.Not only operation effectiveness is poor, and operates dangerously, is prone to accidents.The major defect that its setting-out parts also exist is that fault rate is high especially, often occurs blocking, leaks, defect such as insufficient pressure, increases many troubles and loss of cycle to the operator.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of knapsack sprayer is provided, and this sprayer should have the characteristics that pressure is big, lift is high, and simple in structure, durable in use, fault rate is low again.
The technical scheme that the utility model proposes is:
The Backpack type high-pressure sprayer comprises staving, setting-out parts and accumulator, is shaped on backpack strip on the staving, and described setting-out parts comprise cylindrical shell, the piston that moves and the depression bar that drives the piston motion in cylindrical shell; The piston block that described piston comprises piston rod and is fixed on the piston rod top, the outer circumference surface of piston block is slightly smaller than the internal diameter of cylindrical shell, and be shaped at least one locating slot on the outer circumference surface, all be equipped with a sealing ring in each locating slot around whole outer circumference surface.
Described cylindrical shell is made with stainless steel.
The utility model is because its setting-out parts have adopted piston block that is provided with sealing ring and the metal cylinder that matches with it, and the hydraulic pressure that is obtained enlarges markedly, and directly sprays lift and is increased to 5-6 rice, and horizontal spray lift is increased to 10-12 rice.When being used for the fruit tree operation, only need standing in tree and just can carry out deinsectization, weeding, fertilising, sterilization to whole tree sprinkling down, not only spray effect is good, and has eliminated the potential safety hazard that causes owing to climbing the tree fully.In addition, this setting-out parts rational in infrastructure, durable in use, fault rate significantly reduces, defect such as no longer include obstruction, leak, the operator does not have trouble and the loss of cycle that frequent maintenance brings.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is a left TV structure schematic diagram of the present utility model.
Fig. 3 is the structure for amplifying schematic diagram of setting-out parts of the present utility model.
Fig. 4 is the structure for amplifying schematic diagram of piston element of the present utility model.
The specific embodiment
As shown in the figure, this knapsack sprayer, comprise other parts such as staving 1, setting-out parts 2, accumulator 4, sebific duct 5 and backpack strip, its middle cylinder body 2-2 communicates with the accumulator 4 of staving outside by the positioning pipe 6 of its bottom, and the port of export of the bottom of cylindrical shell 2-2 and accumulator 4 is equipped with check valve respectively.During operation, the operator with its back of the body at back, on the other hand hand-held spray lance, another hand is pulled handle 6 repeatedly, the liquid in the staving just continue to flow cylindrical shell 2-2, cylindrical shell 2-2, accumulator 4, sebific duct 5 in the setting-out parts spray from spray lance at last.Said structure is exactly the structure of existing knapsack sprayer.
The main improvement that the utility model is done is to change piston structure into piston block by original leather cup structure.Specifically: described setting-out parts comprise cylindrical shell 2-2, the piston that moves and the depression bar 3 that drives the piston motion in cylindrical shell, described piston comprises piston rod 2-5 and is fixed on the piston block 2-4 on piston rod top (preferentially adopting brass to make), the outer circumference surface of piston block is slightly smaller than the internal diameter of cylindrical shell, and be shaped at least one locating slot 2-4-1 on the outer circumference surface, all be equipped with a sealing ring 2-3 (piston block that only shows a sealing ring among the figure) in each locating slot around whole outer circumference surface.When piston block moves in cylindrical shell, do not contact, only external diameter and the cylinder inboard wall by sealing ring 2-3 rub (steam-cylinder piston and the piston ring of the similar engine of its structure) with cylinder inboard wall.Obviously, cylinder inboard wall should be smooth as far as possible, with the resistance of reducing friction.So cylindrical shell has selected for use metal material (preferred stainless steel) to make, to satisfy not only firm but also smooth requirement.Add O-ring seals its specific structure and characteristic, thereby can in cylindrical shell, produce bigger pressure.
Among the figure: the effect of spacer 2-6 is the axial location that remains on cylindrical shell for the motion of piston rod 2-5; The effect of stage clip 2-7 is for depression bar 3 being applied a pulling force that makes progress, so that open check valve sucks cylindrical shell with liquid in bucket.
