Abstract

The utility model discloses a spraying device which is mainly used for spraying pesticide for fruit trees, composed of a water cylinder, an energy storing device, a crank and a link mechanism; a pressing cover of the water cylinder is vertically fixed on a base. A lower chamber of the water cylinder is provided with a water inlet. A water outlet is arranged at the bottom part of the energy storing device. The lower part of the base is also provided with a clamping plate and a fixing device for an eccentric shaft. The spraying device overcomes the defects of big volume and big weight of the whole machine of the existing product. The utility model has the advantages of convenient carrying, convenient operation and low manufacturing cost.

Description

A kind of sprayer

The utility model belongs to a kind of sprayer unit, relates in particular to a kind of sprayer that is used for the fruit tree spraying medicine.

Before the utility model is made, multiple this type of sprayer is arranged in the public technology.Its structure comprises water vat, accumulator, and drives piston moves in the water vat crank, linkage, and water vat communicates with accumulator through check valve.Water vat is established water inlet, sets out the mouth of a river on the accumulator.During work, by manpower or foot-operated or crank handle, linkage, piston is moved in water vat, thereby cause into water, and hydraulic pressure is gone into accumulator, then, fog-spray nozzle relies on the press water in the accumulator to finish spraying work.But the shortcoming of existing this class sprayer is: the complete machine structure heaviness, volume is big, not only use inconvenience, and manufacturing cost is also higher, thereby very difficult penetration and promotion.

Task of the present utility model provides a kind of improved sprayer.Its complete machine structure is light and handy, not only carry, easy to use, and manufacturing cost also reduces greatly.

The purpose of this utility model reaches by following technical proposals.The utility model comprises water vat, accumulator and drives crank, the linkage that piston moves in the water vat, water vat communicates with accumulator through check valve, water inlet is established in the water vat chamber, set out the mouth of a river on the accumulator, its structural feature is: vertically be packed on the base by gland behind water vat and the accumulator suit, movable fixing device is established in the base bottom, and base one side is established the crank axle bed.

The utility model in the specific implementation, movable fixing device is made of the left and right support plate of the base that is arranged on the base bottom, eccentric shaft and eccentric shaft handle, forms arc groove between the left and right support plate of base.

The utility model is compared with the product of prior art, owing to vertically be fixed on the base by gland after with water vat, accumulator suit; Movable fixing device is established in the base bottom; Therefore the base sidepiece is provided with the crank axle bed, thereby has omitted the base and the support of existing product heaviness, and machine volume, weight are greatly reduced, and cost of manufacture also reduces greatly, not only carries, uses more convenient, and effect is obvious.

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Fig. 1 shows front view for the present embodiment partial cutaway;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the upward view of Fig. 1;

Fig. 4 is that the A of Fig. 3 crank axle bed is to schematic diagram.

Referring to accompanying drawing.As can be seen from Figure 1, water vat 6 is inserted in the accumulator 7, water vat 6 and accumulator 7 are circle, water vat 6 can adopt copper pipe, and the shell 9 of accumulator 7 can adopt zinc-plated light-wall pipe, and two is smooth open type, gland 4 is fixed on the base 21 (referring to Fig. 2) gland nut 3 mainly for fixing water vat 6 through bolt 26 usefulness nuts 25 with gland 4, gland 4 and base 21 make it form sealed space the sealing of water vat 6 and accumulator 7 two-port, and sealing ring the 5, the 23rd is for leakproof is provided with.Piston 8 is set in the water vat, and piston 8 bottoms are water vat cavity of resorption 10, open two holes on the base 21 of water vat cavity of resorption 10 bottoms, and a hole is installed into the mouth of a river 18, and water inlet 18 is by the 19 control water inlets of water inlet check valve; Another hole forms pipeline 12 and communicates with accumulator 7, and is controlled by check valve 11, and accumulator 7 bottoms also are provided with delivery port 20, and delivery port 20 and fog-spray nozzle be not through sebific duct be connected (drawing among the figure).Piston 8 is connected with connecting rod 1 through piston rod 2, and connecting rod 1 other end is connected with crank 13 again, and crank 13 is sleeved on (referring to Fig. 3) on the crank fulcrum shaft 27, and crank fulcrum shaft 27 is packed on the crank axle bed 22 of base 21.

Also can find out from Fig. 1, Fig. 3, base 21 bottoms are provided with base left supported plate 16, base right supported plate 14, support plate forms arc groove 17, and left supported plate 16 has two, they are arcuation setting (referring to Fig. 3) relatively, right supported plate 14 also has two, and eccentric shaft 24 is set on the right supported plate 14, and eccentric shaft handle 15 can be handled eccentric shaft 24 and rotate.

Making principle on the operating process of this sprayer reaches roughly is like this: the rural area generally uses bucket to hold soup at present, at this moment can be shelved on the bucket edge to sprayer earlier, being about to the bucket edge embeds in the groove 17, pull eccentric shaft handle 15 eccentric shaft 24 rotations are compressed with bucket, reach the fixedly purpose of sprayer.Then, pull crank 13 (can set up boosting-rod), make connecting rod 1 upper and lower activity, connecting rod 1 drives piston rod 2, piston 8 upper and lower moving at this moment.When moving on the piston 8, the soup in the bucket enters water vat 6 cavity of resorptions 10 through water inlet 18 (but on the water inlet sebific duct of suit suitable length) under check valve 19 controls; When piston 8 moved down, the soup in the piston cavity of resorption 10 was pushed down in the accumulator 7 in check valve 11 controls through pipeline 12, so continuous operation, and soup constantly is pressed into accumulator 7.This moment is if open the fog-spray nozzle operation (delivery port can be decided as required to sebific duct length between the fog-spray nozzle) of just spraying.
