Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention clearer and easier to understand, the invention is further explained by combining the drawings and the detailed implementation mode:

referring to fig. 1, the automatic pipe collecting machine for pesticide spraying disclosed by the invention comprises paired vertical frames 1 arranged side by side from left to right, a mounting table 2 arranged at the top of the two vertical frames 1, a motor 3 arranged on the mounting table 2, a plunger pump 4 for delivering pesticide, a winding roller 5 rotatably connected between the two vertical frames 1 and arranged below the mounting table 2, and a hose 6 wound on the winding roller 5 and used for delivering pesticide. Wherein the inlet end of the hose 6 is in communication with the outlet end of the plunger pump 4 and the outlet end of the hose 6 is slidably arranged through a pipe feeding mechanism 7 arranged at the front side of the two stands 1 and adapted to be provided with a spray pipe (not shown in the figure) for spraying the chemical. The pipe conveying mechanism 7 comprises reciprocating lead screws 72 arranged at the front sides of the two stands 1, and the pipe conveying mechanism 7 drives the hose 6 to reciprocate left and right in a lead screw transmission mode. In operation, the motor 3 is used as a main driving source, and the transmission mechanism 8 is arranged among the plunger pump 4, the take-up roller 5 and the reciprocating screw 72, so that the motor 3 selectively drives the plunger pump 4 or the take-up roller 5 to act.

Referring to fig. 2, the transmission mechanism 8 includes a rotating main shaft 81 rotatably connected in the plunger pump 4, a one-way bearing 82 provided on the rotating main shaft 81, and a first belt transmission member 83 connecting a left end of the rotating main shaft 81 and a left end of the take-up roller 5; in addition, a second belt transmission assembly 84 is connected between the left end of the take-up roller 5 and the left end of the reciprocating screw 72. An inner ring of the one-way bearing 82 is mounted on the rotating main shaft 81, and an outer ring of the one-way bearing 82 is mounted on the driving pulley 831. When the motor 3 works, the first belt transmission component 83 drives the winding roller 5 and the reciprocating screw 72 to rotate in a belt transmission mode, so that the hose 6 is automatically wound around the winding roller 5 in a mode of winding from left to right and from inside to outside. The two ends of the rotating main shaft 81 extend along the axial direction and penetrate out of the plunger pump 4, and the right end of the rotating main shaft 81 is rotatably connected with the output shaft of the motor 3 through a coupler. The rotary main shaft 81 is assembled with a crankshaft and other components (not shown) inside the plunger pump 4 to form a crank mechanism. When the motor 3 rotates forward, the rotating main shaft 81 drives the crank link mechanism to act, so as to drive the plunger pump 4 to act, the one-way bearing 82 is unlocked, and the actions of the rotating main shaft 81 and the first belt transmission component 83 are not interfered with each other. When the motor 3 rotates reversely, the rotating main shaft 81 drives the crank link mechanism to move reversely, the inlet and outlet directions of the liquid in the plunger pump 4 are opposite, the liquid flow is limited by the one-way valve in the plunger pump 4, so that the plunger pump 4 is relatively closed, the one-way bearing 82 is locked at the moment, and the rotating main shaft 81 drives the first belt transmission assembly 83 to move through the one-way bearing 82.

Due to the different rotation speeds of the rotating spindle 81, the take-up roller 5 and the reciprocating screw 72, the coordinated operation among the plunger pump 4, the take-up roller 5 and the pipe feeding mechanism 7 can be ensured by selecting the driving pulley 831, the driven pulley 832, the driving sprocket 841 and the driven sprocket 842 with different diameters in the actual manufacturing process.

When the motor 3 rotates forwards, the one-way bearing 82 is locked, the plunger pump 4 inputs pesticide into the hose 6, and at the moment, the hose 6 can be pulled out to spray pesticide and the like. Meanwhile, the second belt transmission assembly 84 enables the winding roller 5 and the reciprocating screw 72 to run synchronously all the time, that is, during the winding and unwinding process of the hose 6, the winding roller 5 and the reciprocating screw 72 rotate synchronously, so that the condition that the winding position of the hose 6 on the winding roller 5 does not correspond to the penetrating position of the hose 6 on the pipe conveying mechanism 7 during the later winding is avoided. When the motor 3 rotates reversely, the one-way bearing 82 can rotate freely, the plunger pump 4 stops working, so that the whole action of the transmission mechanism 8 is realized, the reciprocating screw 72 rotates at the moment, and the winding roller 5 drives the hose 6 to wind.
