Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation equipment technology, and in particular to a double-end connection mechanism for a tobacco sprayer. Background Technology

[0002] In tobacco cultivation, regular spraying operations such as watering, fertilizing, and applying pesticides are necessary to ensure the healthy growth and good development of the plants. Traditional spraying devices typically use fixed nozzles or simple single-end connection structures, which have many limitations. For example, some fixed nozzles cannot adjust the spraying angle and range according to the growth stage of the tobacco and actual needs, while some single-end connection devices have poor sealing during liquid transmission, which can easily lead to liquid leakage, wasting resources and affecting the spraying effect. In addition, some existing adjustable-angle spraying devices have complex structures, are inconvenient to operate, and lack stability during rotation, making it difficult to meet the requirements of large-area, uniform spraying. Currently, there is no double-end connection mechanism on the market that can simultaneously achieve efficient and sealed liquid transmission, flexible multi-angle rotation adjustment, and stable structural adaptability specifically for the needs of tobacco hanging spraying operations.

[0003] A search revealed that the document with publication number "CN216058925U" mentions "a portable tobacco sprayer, comprising: a frame and wheels, the frame being divided into a horizontal section and an inclined section, the wheels being rotatably connected to the horizontal section of the frame for pushing the frame." In use, by setting up the frame and installing a mounting base on it, an electric sprayer containing pesticide solution can be placed on the mounting base during operation. The entire device can be easily moved using the handles on the frame and the wheels, eliminating the need for manual carrying of the sprayer, greatly reducing the burden on workers, and making it labor-saving and portable. This utility model, by setting up a double-support rod and a spray adjustment mechanism, allows for adjustment of the height of the moving frame and the number of spray nozzles according to the actual height of the herbs and the planting area, thus adjusting the spray height and range and greatly improving work efficiency.

[0004] However, existing tobacco spraying devices mostly use fixed nozzles and devices that can only be adjusted in one direction, which cannot meet the diverse needs of tobacco at different growth stages for spraying angle and range. They cannot be precisely adjusted according to actual conditions. At the same time, due to the lack of effective driving and adjustment mechanisms, traditional devices are difficult to achieve large-scale and uniform spraying, and cannot meet the needs of large-scale tobacco planting.

[0005] Therefore, we provide a double-end connection mechanism for tobacco spraying to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6As shown, this utility model provides a technical solution: a double-end connection mechanism for a tobacco sprayer, including a fixed bracket 1, a connecting block 2 fixedly connected to the lower surface of the upper end of the fixed bracket 1, a protective pipe 3 fixedly connected to the lower end of the connecting block 2, an inlet pipe 4 provided inside the protective pipe 3, a top connecting assembly 5 fixedly connected to the lower surface of the inlet pipe 4, the top connecting assembly 5 including a diversion pipe 501 fixedly connected to the lower surface of the inlet pipe 4, a rotating collar 502 fixedly connected to the lower end of the diversion pipe 501, a fixed sealing ring 503 provided below the rotating collar 502, and a fixed sealing ring 503 fixedly connected to the lower end of the fixed sealing ring 503. There is an upper rotating shaft 504, and an upper connecting plate 6 is fixedly connected to the lower part of the upper rotating shaft 504. A rotating pipe 7 is installed inside the upper connecting plate 6. A first flexible hose 8 is installed on the lower surface of the upper connecting plate 6. A first bidirectional nozzle 9 is installed at the lower end of the first flexible hose 8. A second flexible hose 10 is installed at the lower end of the first bidirectional nozzle 9. A second bidirectional nozzle 11 is fixedly connected to the lower end of the second flexible hose 10. A bottom rotating connecting assembly 12 is provided below the second bidirectional nozzle 11. The bottom rotating connecting assembly 12 includes a bearing 1201 installed below the second bidirectional nozzle 11. A lower connecting plate 1202 is provided below the bearing 1201.

[0033] Furthermore, the protective pipe 3 is a rectangular column structure made of stainless steel. The inner diameter of the protective pipe 3 is larger than the outer diameter of the inlet pipe 4. The inlet pipe 4 is a straight pipe made of corrosion-resistant plastic. The protective pipe 3 is fixedly installed at the lower end of the connecting block 2. The inlet pipe 4 is located inside the protective pipe 3. When the liquid flows inside the inlet pipe 4, the protective pipe 3 wraps around the inlet pipe 4 from the outside, preventing external damage such as collision and friction to the inlet pipe 4.

[0034] Furthermore, the diverter pipe 501 is welded to the inlet pipe 4, the diverter pipe 501 is welded to the rotating collar 502, and the fixed sealing ring 503 is welded to the upper rotating shaft 504. The edge of the rotating collar 502 is inverted triangular, and the edge of the fixed sealing ring 503 is upright triangular. The rotating collar 502 and the fixed sealing ring 503 are snapped together. The diverter pipe 501 is fixed to the inlet pipe 4 by welding, receives the liquid delivered by the inlet pipe 4, and then transfers the liquid to the rotating collar 502 by welding. The rotating collar 502 and the fixed sealing ring 503 are snapped together by their respective triangular edges to achieve sealed liquid transmission, while allowing a certain degree of relative rotation. The fixed sealing ring 503 then transfers the liquid and rotation to the upper rotating shaft 504 by welding.

[0035] Furthermore, the inlet end of the rotating pipe 7 is connected to the upper rotating shaft 504 via a rotating collar 502 and a fixed sealing ring 503. The rotating pipe 7 is made of corrosion-resistant plastic material. The liquid and rotation transmitted by the upper rotating shaft 504 are transmitted to the inlet end of the rotating pipe 7 through the cooperation of the rotating collar 502 and the fixed sealing ring 503. The liquid flowing through the rotating pipe 7 is delivered to the first hose 8 for spraying. The rotating pipe 7 and the first hose 8 are also connected via the rotating collar 502 and the fixed sealing ring 503.

[0036] Furthermore, the first hose 8 and the first bidirectional nozzle 9 are fixedly connected by bolts. The length of the second hose 10 is greater than the length of the first hose 8. The first bidirectional nozzle 9 and the second bidirectional nozzle 11 are symmetrically arranged. After the liquid flows out of the rotating pipe 7, it enters the first hose 8. The first hose 8 is fixedly connected by bolts to transport the liquid to the first bidirectional nozzle 9, which performs the spraying operation. At the same time, the liquid is transported through the second hose 10 to the second bidirectional nozzle 11, which performs the spraying operation. Because the second hose 10 is longer, it has a larger range of motion. And because the two nozzles are symmetrically arranged, the spraying range is more uniform, and both sides of the tobacco leaves can be sprayed at the same time.

[0037] Furthermore, the lower end of the second bidirectional nozzle 11 is fixedly connected to the inner ring of the bearing 1201 via a connecting shaft, and the outer ring of the bearing 1201 is fixedly connected to the lower connecting plate 1202. A lower rotating shaft 1203 is fixedly connected to the lower surface of the lower connecting plate 1202, and a rotating motor 1204 is connected to the lower end of the lower rotating shaft 1203 via a flat key. A protective cover is installed on the outside of the rotating motor 1204. After the rotating motor 1204 is started, its output shaft drives the lower rotating shaft 1203 to rotate via a flat key connection. The lower rotating shaft 1203 drives... The lower connecting plate 1202 rotates, and since the bottom rotating connecting assembly 12 and the top connecting assembly 5 are connected by a spraying device, which includes a first hose 8, a first bidirectional nozzle 9, a second hose 10 and a second bidirectional nozzle 11, the entire spraying device will rotate, thereby changing its position. At the same time, due to the setting of the bearing 1201, the rotating collar 502 and the fixed sealing ring 503, the spraying device can also adjust its angle while rotating around the lower rotating shaft 1203.

[0038] Furthermore, a fixing rod 13 is fixedly connected to the inner side of the fixing bracket 1. The output shaft of the rotating motor 1204 passes through the fixing rod 13 and is connected to the lower rotating shaft 1203 by a key. The fixing rod 13 is made of stainless steel. The fixing rod 13 is fixedly installed on the inner side of the fixing bracket 1. The rotating motor 1204 is installed on the fixing rod 13. Its output shaft passes through the fixing rod 13 and is connected to the lower rotating shaft 1203 by a key. When the rotating motor 1204 is working, the fixing rod 13 provides stable support for the motor and prevents the motor from shaking or shifting during operation.

[0039] Working Principle: In operation, external liquid first enters the device through the inlet pipe 4, which is located inside the protective pipe 3, protecting it. After flowing through the inlet pipe 4, the liquid enters the diversion pipe 501, which transmits the liquid to the rotating collar 502. The rotating collar 502 and the fixed sealing ring 503 are engaged by their triangular edges, simultaneously sealing and transmitting the liquid while transmitting rotation to the fixed sealing ring 503. The fixed sealing ring 503 transmits both the liquid and rotation to the upper rotating shaft 504. The upper rotating shaft 504, through the cooperation of the rotating collar 502 and the fixed sealing ring 503, transmits both the liquid and rotation to the rotating pipe 7. After flowing through the rotating pipe 7, the liquid enters the first... The first hose 8 delivers liquid to the first bidirectional nozzle 9, which then begins spraying. Simultaneously, the liquid is delivered to the second bidirectional nozzle 11 via the second hose 10, which also sprays synchronously. The symmetrically arranged nozzles achieve uniform spraying. The rotating motor 1204 is started, and its output shaft drives the lower rotating shaft 1203 to rotate via a flat key. The lower rotating shaft 1203 drives the lower connecting plate 1202 to rotate. Under the action of the bearing 1201, the top rotating collar 502, and the fixed sealing ring 503, the entire hanging spray device rotates with the lower connecting plate 1202 to change position and adjust its own angle to ensure that the spraying range fully covers the tobacco area. This completes the use of a double-end connection mechanism for a tobacco hanging sprayer.
