DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0026] Please refer to Figures 1-3 The utility model provides a technical scheme: an anti-blocking nozzle mechanism for agricultural pesticide spraying machine, which comprises a spray rod 1, outer screw pipes 101 symmetrically and communicatively arranged on both sides of the upper end of the spray rod 1, an atomizing nozzle 2 rotatably installed at the lower end of the spray rod 1, a valve seat 102 arranged in the middle part of the spray rod 1, a valve piece 3 rotatably installed on the inner side of the valve seat 102, and a handle 301 installed at the front end of the valve piece 3. A deimpurity mechanism for separating solid medicament from liquid medicament to reduce the blocking of the atomizing nozzle 2 by solid impurities is arranged between the valve seat 102 and the atomizing nozzle 2 on the spray rod 1.
[0027] Specifically, as Figure 1 and Figure 2As shown, the impurity removal mechanism includes a side pipe 103 connected between the left end of the spray rod 1 and between the valve seat 102 and the atomizing nozzle 2, a side cover 4 detachably installed on the left end of the side pipe 103 through a rotating lock portion, a limiting stop block 104 integrally fixed to the inside bottom of the side pipe 103, an inclined filter screen 7 installed between the inside of the spray rod 1 and the limiting stop block 104, and a rubber diaphragm 8 fixed to the inside top of the side pipe 103 and movably contacting the limiting stop block 104 at the lower end. When liquid flows in the inside of the spray rod 1, the rubber diaphragm 8 can rotate towards the side pipe 103. At this time, the impurities on the inclined filter screen 7 can enter the side pipe 103 through the gap between the rubber diaphragm 8 and the side pipe 103, preventing solid impurities from continuously accumulating on the inclined filter screen 7. When there is no liquid flow, the rubber diaphragm 8 can reset to the initial vertical state.
[0028] The rotating lock portion includes an outer screw column 5 vertically and rotatably installed on the side cover 4 and penetrating the side cover 4 inwardly, an inner screw seat 105 integrally fixed to the inside top of the side pipe 103 and corresponding to the outer screw column 5, and a knob 501 installed on the outer end of the outer screw column 5, facilitating the holding and rotating adjustment of the outer screw column 5 by the operator. When the operator holds and rotates the knob 501, the inner end of the outer screw column 5 can be driven to rotate away from the inner screw seat 105 in the side pipe 103. At this time, the locking state between the side cover 4 and the side pipe 103 can be contacted, and the side cover 4 can be removed from the side pipe 103 for discharging the solid impurities collected between the side cover 4 and the side pipe 103.
[0029] Meanwhile, a sealing rubber gasket 401 is installed on the inside of the end of the side cover 4 close to the side pipe 103, covering the outer end of the side pipe 103, to flexibly seal the connection gap between the side cover 4 and the side pipe 103, preventing the liquid in the side pipe 103 from overflowing through the connection gap between the side cover 4 and the side pipe 103, thereby improving the sealing effect of the side cover 4 installed on the side pipe 103.
[0030] Specifically, as shown in Figure 2 The included angle between the inclined surface of the inclined filter screen 7 and the center line of the spray rod 1 is 120°-150°. In actual design, manufacture and use, the inclined angle of the inclined filter screen 7 can be adjusted according to the use scene and customized needs. The inclined filter screen 7 with a small included angle has a smaller filtering area and better flow-through of the medicament through the inclined filter screen 7, but the separation effect of the solid impurities on the inclined filter screen 7 is poor. The inclined filter screen 7 with a large included angle has a larger filtering area, which increases the resistance of the medicament passing through the inclined filter screen 7, but the separation effect of the impurities on the inclined filter screen 7 is better, which can prevent the solid impurities from continuously accumulating on the filtering surface of the inclined filter screen 7.
[0031] Specifically, as shown in Figure 1 and Figure 2As shown, the upper end of the spray rod 1 is fixedly connected with a fixed buckle 6, the upper end of the fixed buckle 6 is rotatably installed with an upper rotating buckle 601, the inner sides of the fixed buckle 6 and the upper rotating buckle 601 are both installed with anti-skid pieces 602, the anti-skid pieces 602 are made of vulcanized rubber material, which can effectively increase the contact area and contact friction between the fixed buckle 6 and the upper rotating buckle 601 and the fixed rod, and prevent the spray head mechanism from being offset and shaken under the force of the fixed rod after installation.
[0032] Working principle: when in use, the spray rod 1 can be installed and fixed on the fixed rod of the medicament spraying device through the fixed buckle 6, the upper rotating buckle 601 and the fastener, then the medicine supply pipeline of the medicine box is connected with the outer screw pipe 101 through the infusion hose to establish a liquid connection, and the assembly operation of the spray head mechanism is completed, when the actual spraying operation is performed, the operator holds and rotates the rotating handle 301 to adjust the opening and closing of the spray head mechanism and the adjustment of the spraying flow, the medicament can enter the spray rod 1 through the medicine supply pipeline and the outer screw pipe 101, and the medicament can flow vertically downward in the spray rod 1, when the medicament passes through the inclined surface filter screen 7 between the valve seat 102 and the atomizing nozzle 2, the inclined surface filter screen 7 can filter the medicament, and the filtered medicament can continue to flow downward and be sprayed and discharged through the atomizing nozzle 2, and the impurities filtered out can be guided into the cavity between the side pipe 103 and the side cover 4 along the inclined surface of the inclined surface filter screen 7 and the movable rubber diaphragm 8 under the combined action of liquid flow and gravity to be collected, so as to prevent the solid impurities from continuously affecting the normal work of the inclined surface filter screen 7 and the atomizing nozzle 2 in the spray rod 1.
[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
