Description

Technical Field

[0001] The utility model relates to the technical field of directional spraying for plant protection, in particular to a directional spraying machine for plant protection. Background Art

[0002] Plant protection refers to a comprehensive approach to agricultural production, focusing on prevention. It applies agricultural, biological, chemical, physical, and mechanical techniques, as well as effective ecological measures, to protect crops from pests, diseases, weeds, and rodents, ensuring healthy plant growth. It is a form of plant medicine, focusing on research and prevention of major plant diseases, insect pests, and weeds, thereby improving plant yields and quality.

[0003] At present, in the process of using chemical, biological and other agents to control plant diseases, pests and weeds, the existing spraying devices generally do not have the function of controlling the spraying range. Therefore, during the spraying process, the disease, pest and weed control drugs used for one type may drift onto another adjacent type of crops, thereby causing harm or pesticide damage to the other type of crops. In addition, when the spraying device just starts spraying water or stops watering, the water flow is unstable and will flow to other locations, and may also flow to the bottom of the device, resulting in waste of drugs and difficulty in cleaning the device.

[0004] So we proposed a plant protection directional sprayer to solve the problems mentioned above. Utility Model Content

[0005] The purpose of the present utility model is to provide a directional sprayer for plant protection, so as to solve the problems raised in the above-mentioned background technology that the current spraying devices generally do not have the function of controlling the spraying range, which may cause harm to another type of crops and the medicine may flow to the bottom of the device when spraying or stopping water, thereby causing waste of medicine.

[0006] The control rod is connected with the control arm of the U-shaped base, and the control arm is connected with the control arm at the bottom end.

[0007] Preferably, the support rod forms a rotating structure with the base plate through the damping shaft, and the angle between the baffle and the support rod is an acute angle.

[0008] Preferably, the water inlets of the water inlet pipe are distributed at equal intervals, and the end of the water inlet pipe is in a closed state.

[0009] Preferably, the recovery tray is in the shape of an inverted truncated cone as a whole.

[0010] Preferably, a notch adapted to the pull rod is opened on the left side of the sprayer housing, and the pull rod forms a sliding structure with the sprayer housing through the notch, the right end of the pull rod is arc-shaped, and both sides of the groove are arc-shaped.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the plant protection directional sprayer,

[0012] (1) Multiple water inlets distributed at equal intervals make water absorption more efficient, and the smaller the water inlet, the larger the powder blocks are squeezed and crushed by the water inlet, so that the medicine and water in the water tank body are mixed more thoroughly, thereby improving the quality of the mixed medicine.

[0013] (2) When the sprinkler head just starts spraying water or stops spraying water, the water will flow into the recovery tray and then flow back into the water tank through the recovery pipe at the bottom of the recovery tray, thereby circulating it and preventing the medicine from flowing to the bottom of the device, thereby reducing the waste of medicine.

[0014] (3) By pushing or pulling the push rod, the U-shaped plate in front of the push rod moves forward or backward, and the groove on the left side of the U-shaped plate is arc-shaped on both sides, and the top of the pull rod set on the left side of the groove is also arc-shaped, so that there will be no large resistance when pushing the push rod, thereby realizing the forward or backward movement of the U-shaped plate, and then adjusting the extension distance of the sprinkler head, so that the water in the sprinkler head can be sprayed farther or closer, thereby avoiding manual handling and reducing manpower consumption.

[0015] (4) When the inside of the groove is damaged and stuck, by pulling the pull rod, the spring outside the pull rod is compressed, so that the pull rod slides to the outside of the groove, thereby releasing the U-shaped plate and increasing the fault tolerance of the U-shaped plate movement.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model provides a technical solution: a directional sprayer for plant protection, comprising a sprayer housing 1, a U-shaped plate 17 installed inside the sprayer housing 1, sliders 3 installed on both sides of the U-shaped plate 17, a groove 19 opened on the left side of the U-shaped plate 17, a pull rod 20 provided on the left side of the groove 19, and a spring 21 installed on the periphery of the pull rod 20, a water spray head 2 installed inside the U-shaped plate 17, a push rod 18 connected to the rear of the U-shaped plate 17, a water injection pipe 4 installed on the top of the sprayer housing 1, and a water pump 5 connected to the end of the water injection pipe 4, and a water tank body 8 connected to the bottom of the water pump 5. A water tank top cover 6 is embedded on the right side of the top of the water tank body 8, the water inlet end of the water pump 5 is connected to the water inlet pipe 7, and a water inlet 16 is provided at the end of the water inlet pipe 7. An electric telescopic rod 11 is installed at the bottom of the sprayer housing 1, and a recovery disk 9 is installed on the outer periphery above the electric telescopic rod 11, and a recovery pipe 10 is connected to the right side of the recovery disk 9. The end of the recovery pipe 10 is connected to the left side of the water tank body 8. A bottom plate 12 is installed at the bottom of the electric telescopic rod 11, and the two sides of the bottom of the bottom plate 12 are connected to the support rod 15 through a damping shaft 13, and a baffle 14 is installed on one side of the lower end of the support rod 15.

[0025] The support rod 15 forms a rotating structure with the base plate 12 through the damping shaft 13, and the angle between the baffle 14 and the support rod 15 is an acute angle. By pulling the support rod 15, the damping shaft 13 is compressed, so that the support rod 15 rotates around the damping shaft 13, and a protrusion is provided on the top of the support rod 15, so that the support rod 15 cannot continue to rotate after it is rotated until the baffle 14 is parallel to the ground. After rotating to the required position, the support rod 15 is inserted into the ground so that the baffle 14 is attached to the ground, so that when the sprinkler head 2 sprays water, the base plate 12 is more stable, thereby reducing the situation where the device tilts or overturns during water spraying.

[0026] The water inlets 16 opened on the water inlet pipe 7 are distributed at equal intervals, and the end of the water inlet pipe 7 is in a closed state. The equally spaced water inlets 16 make water absorption more efficient, and the water inlet 16 is small, so that the enlarged medicine powder blocks are squeezed and crushed by the water inlet 16, thereby making the medicine and water in the water tank body 8 mixed more thoroughly, thereby improving the mixing quality of the medicine solution.

[0027] The recovery tray 9 is in the shape of an inverted truncated cone. When the sprinkler head 2 just starts spraying water or stops spraying water, the water will flow into the recovery tray 9 and then flow back into the water tank body 8 through the recovery pipe 10 at the bottom of the recovery tray 9, thereby circulating it and reducing the waste of medicine.

[0028] The left side of the sprayer housing 1 is provided with a slot adapted to the pull rod 20, and the pull rod 20 forms a sliding structure with the sprayer housing 1 through the slot. The right end of the pull rod 20 is arc-shaped, and the two sides of the groove 19 are arc-shaped. By pushing or pulling the push rod 18, the U-shaped plate 17 in front of the push rod 18 moves forward or backward, and the two sides of the groove 19 on the left side of the U-shaped plate 17 are arc-shaped, and the top of the pull rod 20 set on the left side of the groove 19 is also arc-shaped, so that when the push rod 18 is pushed, there will be no large Resistance, thereby realizing the forward or backward movement of the U-shaped plate 17, and then adjusting the extension distance of the sprinkler head 2, so that the water in the sprinkler head 2 can be sprayed out of a farther or closer distance, thereby avoiding manual handling and reducing manpower consumption. When the groove 19 is damaged and stuck, by pulling the pull rod 20, the spring 21 outside the pull rod 20 is compressed, so that the pull rod 20 slides to the outside of the groove 19, thereby releasing the U-shaped plate 17, and then increasing the fault tolerance of the movement of the U-shaped plate 17.

[0029] Working principle: When using the plant protection directional sprayer, first, use a cart to move the machine body to the required location, pull the water tank top cover 6 to expose the opening on the top of the water tank body 8, and then pour the powder and water into the water tank body 8 through the opening to mix them;

[0030] Next, take the sprayer out of the cart and pull the support rod 15 to compress the damping shaft 13, so that the support rod 15 rotates around the damping shaft 13. A bump is provided on the top of the support rod 15 so that the support rod 15 cannot rotate further after it rotates until the baffle 14 is parallel to the ground. After rotating to the required position, the support rod 15 is inserted into the ground so that the baffle 14 is attached to the ground. This makes the bottom plate 12 more stable when the sprinkler head 2 sprays water, thereby reducing the possibility of the device tilting or overturning during spraying.

[0031] Next, the electric telescopic rod 11 is activated to adjust it to the required height, and then the water pump 5 is activated, so that the water inlet pipe 7 starts to supply water to the water pump 5 through the water inlet 16. Multiple water inlets 16 make water absorption more efficient, and the water inlet 16 is small, so that the enlarged powder blocks are squeezed and crushed by the water inlet 16, so that the medicine and water in the water tank body 8 are mixed more thoroughly, thereby improving the quality of the medicine-water mixture. The water entering the water pump 5 is sent to the U-shaped plate 17 inside the sprayer housing 1 through the water injection pipe 4. A through hole is opened above the U-shaped plate 17, and then the medicine enters the sprinkler head 2 through the through hole, so that it is sprayed in a direction.

[0032] When a place is sprayed and the water spraying distance of the sprinkler head 2 needs to be adjusted, the push rod 18 is pushed to move the U-shaped plate 17 in front of the push rod 18 forward. The groove 19 on the left side of the U-shaped plate 17 is arc-shaped on both sides, and the right end of the pull rod 20 set on the left side of the groove 19 is also arc-shaped, so that there will be no large resistance when pushing the push rod 18, thereby realizing the forward movement of the U-shaped plate 17, and then adjusting the water spraying distance of the sprinkler head 2, so that the water in the sprinkler head 2 can be sprayed to a farther distance, thereby avoiding manual handling and reducing manpower consumption;

[0033] Afterwards, when the groove 19 is damaged and stuck, the pull rod 20 is pulled to compress the spring 21 outside the pull rod 20, so that the pull rod 20 slides toward the outside of the groove 19, thereby releasing the limit of the U-shaped plate 17 and increasing the tolerance of the movement of the U-shaped plate 17;

[0034] Finally, when the sprinkler head 2 is just spraying water or the water is stopped, the water will flow into the recovery tray 9, and the water will flow back to the water tank body 8 through the recovery pipe 10 at the bottom of the recovery tray 9, thereby circulating it and reducing the waste of medicine. Then, when the device needs to be moved for spraying, the support rod 15 is rotated back to the bottom plate 12 to reduce the use space, and then the body is put back into the cart so that the device can be moved by the cart, thereby realizing the mobile spraying of the sprayer and reducing the limitations of the sprayer. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
