Description

Technical Field

[0001] This utility model is a pest and disease control sprayer, belonging to the field of mechanical equipment. Background Technology

[0002] Pest and disease control sprayers are essential tools in agriculture and horticulture for spraying pesticides, insecticides, herbicides, and other chemical agents. Vehicle-mounted sprayers, installed on tractors or other vehicles, are one type of pest and disease control spraying equipment. They are suitable for large areas of farmland, highly efficient, and feature a securely mounted pesticide container on the vehicle body, facilitating easy transport and ensuring stability and convenience during transit. A hose connects a water pump to a spray pipe with a spray head, allowing the pump to draw water from the pesticide container and pump it into the spray pipe. The spray pipe is mounted on a support pillar on the vehicle body via a rotating mechanism, allowing for flexible adjustment of the spray angle to meet different spraying needs. However, when adjusting the spray pipe angle, the redundant hose connected to it also moves. This redundant hose experiences sliding friction with the vehicle body, which can easily damage the hose, affecting its lifespan. Furthermore, the friction between the hose and the vehicle body increases the resistance to adjusting the spray pipe angle. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pest and disease control sprayer to solve the problems mentioned in the background technology. This utility model restricts the relative position of the hose and the vehicle body to prevent the hose from sliding and rubbing against the vehicle body.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a pest and disease control sprayer, comprising,

[0005] A support pillar, mounted on the vehicle body, is used to support the spray pipe, wherein the spray pipe is rotatably connected to the support pillar;

[0006] The spray head is threadedly connected to one end of the spray pipe;

[0007] The hose is installed on the pipe fitting at the end of the spray pipe away from the spray head by a clamp;

[0008] The ring is rotatably installed at the lower end of the support column;

[0009] A horizontal plate is installed horizontally on the side of the ring.

[0010] Elastic rubber rings are glued to the horizontal plate and fitted onto the hose. Multiple elastic rubber rings are provided and are glued to the horizontal plate at equal intervals.

[0011] Bolts, threaded connections, are attached to the outer surface of the ring on the side opposite to the cross plate.

[0012] Furthermore, a transverse hole is provided on the outer surface of the ring away from the horizontal plate. A sleeve is provided on the outside of the transverse hole, concentrically arranged with the transverse hole. One end of the sleeve is connected and fixed to the ring. A circular nut is installed in the middle of the sleeve. The circular nut is threadedly connected to the bolt. Two spacer rings are fitted on the shank of the bolt and fixed to the shank of the bolt. The two spacer rings are arranged on both sides of the circular nut. The distance between the two spacer rings is half the length of the sleeve. The spacer rings are slidably installed in the sleeve. One end of the bolt passes through the transverse hole and is connected to the support column.

[0013] Furthermore, a limiting ring is provided on both the upper and lower sides of the ring, the limiting ring is in sliding contact with the ring, and the limiting ring is sleeved on the support and connected and fixed to the support.

[0014] Furthermore, a base is fixedly connected to the lower end of the support column, and the upper surface of the base is provided with a plurality of small holes in a ring at equal intervals.

[0015] Furthermore, a support ring is installed at the center of the lower surface of the chassis, and the outer diameter of the support ring is the same as the outer diameter of the support column.

[0016] Furthermore, an annular groove is formed on the outer surface of the upper end of the support column, and a rotating ring that rotates around the support column is installed in the annular groove. A top cover is installed on the upper end of the support column, and two L-shaped plates are symmetrically installed on the annular side of the rotating ring. The end of the spray pipe near the spray head is rotatably installed between the two L-shaped plates.

[0017] Furthermore, a handle is fixedly connected to the end of the spray pipe away from the spray head, and the handle has a "C" shaped structure.

[0018] The beneficial effects of this utility model are:

[0019] 1. The horizontal plate drives the ring to rotate around the support column. After the horizontal plate moves to the desired position, the bolts limit the relative position of the ring and the support column, allowing the position of the horizontal plate to be adjusted as needed. The hose passes through the elastic rubber ring, and the hose between the elastic rubber ring and the spray pipe is in a redundant state. When adjusting the angle of the spray pipe, the hose between the elastic rubber ring and the spray pipe changes position. The hose in contact with the vehicle body does not slide with the vehicle body, reducing the resistance encountered during the adjustment of the spray pipe angle and preventing the hose from being damaged due to friction with the vehicle body.

[0020] 2. The bolt is threaded into the round nut inside the sleeve. At this time, the connection between the bolt and the round nut is in the closed space formed by the two spacers and the sleeve. Thus, the effective threaded connection between the bolt and the round nut is in a closed environment, preventing small debris from entering the round nut and affecting the tightening of the bolt.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1-3This utility model provides a technical solution: a pest and disease control sprayer, including a support column 1 mounted on a vehicle body to support a spray pipe 3. An annular groove is formed on the outer surface of the upper end of the support column 1, and a rotating ring 8 that rotates around the support column 1 is installed in the annular groove. A top cover 7 is installed on the upper end of the support column 1. Two L-shaped plates 6 are symmetrically installed on the annular side of the rotating ring 8. One end of the spray pipe 3 near the spray head 2 is rotatably mounted between the two L-shaped plates 6. The top cover 7 restricts the rotation ring 8 from the support column 1. The L-shaped plates 6, the support column 1, etc., support the spray pipe 3, enabling a rotatable connection between the spray pipe 3 and the support column 1, allowing the rotating ring 8 to rotate around the support column 1 for easy adjustment of the angle of the spray pipe 3. One end of the spray pipe 3 is threadedly connected to a spray nozzle. The spray pipe 3 is connected to a handle 4 at the end away from the spray head 2. The handle 4 has a "C" shaped structure. The lower end of the support column 1 is connected to a chassis 13. The upper surface of the chassis 13 has multiple small holes that are evenly spaced in a ring. A support ring 16 is installed in the middle of the lower surface of the chassis 13. The outer diameter of the support ring 16 is the same as the outer diameter of the support column 1. When the support column 1 is installed on the vehicle body, the screw passes through the small holes on the chassis 13 and is connected to the vehicle body. At this time, the support ring 16 is between the vehicle body and the chassis 13. Under the support of the support ring 16, part of the screw between the chassis 13 and the vehicle body is exposed. If the screw cannot be disassembled normally due to rust later, the bolt 15 can be cut off by sawing through the gap between the screw and the vehicle body.

[0029] See 1- Figure 4The hose 5 is installed on the pipe joint at the end of the spray pipe 3 away from the spray head 2 via a clamp. The ring 12 is rotatably installed at the lower end of the support column 1. Limiting rings 9 are provided on both the upper and lower sides of the ring 12, and these limiting rings 9 slide in contact with the ring 12. The limiting rings 9 are sleeved on the support column 1 and fixedly connected to it. The horizontal plate 10 is installed horizontally on the annular side of the ring 12. Multiple elastic rubber rings 11 are glued to the horizontal plate 10 and sleeved on the hose 5. Multiple elastic rubber rings 11 are equidistantly bonded to the horizontal plate 10. Bolts 15 are threadedly connected to the outer surface of the ring 12 on the side opposite to the horizontal plate 10, causing the horizontal plate 10 to drive the ring 12 to rotate around the support column 1. When the horizontal plate 10 moves to the desired position, the bolts 15 restrict the relative position of the ring 12 and the support column 1, achieving... Adjust the position of the cross plate 10 as needed so that the hose 5 passes through the elastic rubber ring 11, making the hose 5 between the elastic rubber ring 11 and the spray pipe 3 redundant. When water is introduced into the hose 5, the water supports the hose 5 so that its cross-section becomes circular. At this time, the hose 5 expands the elastic rubber ring 11, and the elastic rubber ring 11 undergoes elastic deformation. Under the action of the elastic force of the elastic rubber ring 11, the relative position of the hose 5 and the cross plate 10 remains unchanged. That is, the part of the hose 5 near the spray pipe 3 is always redundant. Therefore, when the angle of the spray pipe 3 is adjusted, the hose 5 between the elastic rubber ring 11 and the spray pipe 3 changes position. The hose 5 in contact with the vehicle body does not slide with the vehicle body, reducing the resistance encountered during the adjustment of the angle of the spray pipe 3, and the hose 5 will not be damaged due to friction with the vehicle body.

[0030] See Figure 4 A transverse hole is provided on the outer surface of the ring 12 away from the side of the horizontal plate 10. A sleeve 14 is provided on the outside of the transverse hole and is arranged concentrically with the transverse hole. One end of the sleeve 14 is connected and fixed to the ring 12. A round nut 18 is installed in the middle of the sleeve 14. The round nut 18 is threadedly connected to the bolt 15. Two spacer rings 17 are fitted on the shank of the bolt 15 and are connected and fixed to the shank of the bolt 15. The two spacer rings 17 are located on both sides of the round nut 18. The distance between the two spacer rings 17 is half the length of the sleeve 14. The spacer rings 17 are slidably installed in the sleeve 14. One end of the bolt 15 passes through the transverse hole and is connected to the support column 1, so that the bolt 15 is threadedly connected to the round nut 18 in the sleeve 14. At this time, the connection part of the bolt 15 and the round nut 18 is in the closed space formed by the two spacer rings 17 and the sleeve 14. Thus, the effective threaded connection part of the bolt 15 and the round nut 18 is in a closed environment, preventing small debris from entering the round nut 18 and affecting the tightening of the bolt 15.
