However, the mobile spraying devices in the prior art generally have the following problems:

[0003] Traditional equipment mostly uses single container or simple multi-container parallel structure, and the liquid processing process is mostly sequential operation, lacking intermittent multi-station collaborative mechanism. When different liquids need to be processed in cycles (such as alternating spraying, cleaning pipeline), the container needs to be frequently replaced or manually intervened, resulting in low operation efficiency and difficulty in meeting the needs of automated and continuous production.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0034] Example 1

[0035] refer to Figures 1-8 As shown, this embodiment discloses a mobile spraying device, including a mobile device body 100 and a spraying assembly 200 fixedly mounted on the mobile device body 100;

[0036] The spraying assembly 200 includes a mounting box 207 mounted on the mobile device body 100, and an intermittent component 202, a carrier component 203, and a spraying component 204 disposed within the mounting box 207. Multiple carrier cylinders 2032 are arranged in a circular array on the carrier component 203, and the spraying component 204 is located below one of the carrier cylinders 2032.

[0037] The mobile device body 100 provides a mobile foundation for the spraying assembly 200, enabling it to reach different working positions. Once moved to the designated position, the entire spraying assembly 200 begins preparation, with each component entering a standby state. This allows the carrier component 203 to orderly move the carrier cylinder 2032 above the spraying assembly 204, facilitating liquid transfer and spraying operations, and improving work efficiency and continuity.

[0038] Intermittent component 202 is fixedly mounted on fixed plate 2021 inside mounting box 207. Intermittent component 202 includes drive mechanism, intermittent mechanism and positioning component 205.

[0039] The device also includes a transmission assembly, which includes a driven wheel 2022 rotatably mounted on a fixed plate 2021. The driven wheel 2022 has multiple positioning grooves 2023 arranged in a circular array. The bottom end of the driven wheel 2022 passes through the fixed plate 2021 via a rotating shaft and is fixedly connected to the transmission disc 2027.

[0040] When the device is started, the drive mechanism begins to work, providing rotational power to the driven wheel 2022. The driven wheel 2022 cooperates with the positioning component 205 through the positioning groove 2023 to achieve intermittent rotation, thereby driving the transmission disk 2027 to rotate intermittently. The intermittent rotation of the driven wheel 2022 is achieved by the engagement and disengagement of the positioning groove 2023 and the positioning component 205. When the positioning component 205 engages with the positioning groove 2023, the driven wheel 2022 is driven to rotate; when the positioning component 205 disengages from the positioning groove 2023, the driven wheel 2022 stops rotating, thus achieving intermittent motion.

[0041] The drive mechanism includes a drive wheel 2025 and a blocking disc 2024 rotatably mounted on a fixed plate 2021. The drive wheel 2025 and the blocking disc 2024 are coaxially distributed. A motor 201 is fixedly mounted on the mounting box 207. The blocking disc 2024 on the upper end of the drive wheel 2025 is connected to the drive end of the motor 201, so that when the drive end of the motor 201 rotates, it drives the blocking disc 2024 and the drive wheel 2025 to rotate synchronously. The notch on the blocking disc 2024 can prevent motion interference between the drive mechanism and the intermittent component 202. The shaft at the bottom end of the drive wheel 2025 passes through the fixed plate 2021 and connects to a gear 2028. At the same time, a gear 2029 is also provided at the bottom end of the drive wheel 2025, which is connected to the gear 2028. A bidirectional lead screw 2026 is fixed on the gear 2029.

[0042] When motor 1 201 starts, it drives the blocking disc 2024 and the driving wheel 2025 to rotate. When the driving wheel 2025 rotates, it drives gear 1 2028 to rotate via the shaft. Gear 1 2028 then drives gear 2 2029 to rotate, thereby causing the double-acting lead screw 2026 to rotate. The power provided by motor 1 201 is transmitted to the driving wheel 2025 through the blocking disc 2024. The driving wheel 2025 then transmits the power to the double-acting lead screw 2026 through gear transmission, realizing multi-stage power transmission and conversion, and providing power support for subsequent movements.

[0043] The positioning component 205 includes a receiving groove 2057 opened on the drive wheel 2025. A limit ring 2052 is fixed on the inner wall of the opening of the receiving groove 2057. A permanent magnet 2053 is slidably arranged in the receiving groove 2057. A pin 2051 is fixed on the permanent magnet 2053. An elastic element 2054 is sleeved on the outer wall of the pin 2051. An electromagnet 2055 is also arranged in the receiving groove 2057. The electromagnet 2055 forms an attraction when the permanent magnet 2053 is energized and a separation when the permanent magnet is de-energized.

[0044] When the drive mechanism needs to be debugged or maintained, the electromagnet 2055 is energized, attracting the permanent magnet 2053 and causing the pin 2051 to retract, thus decoupling the drive mechanism from the intermittent component 202. When the device is working normally, the electromagnet 2055 is de-energized, and the elastic element 2054 causes the pin 2051 to pop out, achieving coupling between the drive mechanism and the intermittent component 202. The attraction of the electromagnet 2055 to the permanent magnet 2053 and the elastic force of the elastic element 2054 are used to extend and retract the pin 2051, thereby controlling the coupling and decoupling of the drive mechanism from the intermittent component 202, which facilitates the debugging, maintenance and normal operation of the device.

[0045] The support assembly 203 is fixedly mounted on the transmission disk 2027, and multiple support cylinders 2032 are arranged in a circular array on the transmission disk 2027. A water tank 2031 is also coaxially mounted on the transmission disk 2027, and the water tank 2031 is connected to any of the support cylinders 2032 via a connecting pipe. Each support cylinder 2032 is equipped with a connector 2033, and each connector 2033 contains a flow-blocking ball 2034 to prevent liquid leakage.

[0046] During the intermittent rotation of the transmission disc 2027, the carrier cylinders 2032 rotate sequentially above the spraying assembly 204. Once the carrier cylinder 2032 reaches its designated position, it connects to the spraying assembly 204 via the connector 2033. The water tank 2031 replenishes water to one of the carrier cylinders 2032 through a connecting pipe, ensuring a continuous water supply. The other carrier cylinders 2032 contain different colored spraying liquids. The flow-blocking ball 2034 prevents water or spraying liquid from flowing out of the carrier cylinders 2032 when not connected, ensuring the airtightness and safety of the liquid storage.

[0047] When the intermittent component 202 drives the carrier component 203 to connect the carrier cylinder 2032 connected to the water tank 2031 to the spraying component 204, the spraying component 204 can be rinsed. When switching to other carrier cylinders 2032 connected to the spraying component 204, spraying liquid can be injected into the spraying component 204.

[0048] In summary, this embodiment discloses the basic structure and intermittent transmission principle of a mobile spraying device. The mobile device body 100 provides a mobile carrier for the spraying assembly 200, and integrates the intermittent component 202 and the carrier component 203 through the mounting box 207. In the intermittent component 202, motor 1 201 drives the drive wheel 2025 to rotate, which is transmitted to the bidirectional lead screw 2026 through gear 1 2028 and gear 2 2029. At the same time, through the cooperation of the electromagnet 2055 and the permanent magnet 2053 of the positioning component 205, the driving mechanism and the driven wheel 2022 are decoupled by power supply and coupled by power de-energization, thereby controlling the intermittent rotation of the transmission disk 2027, so that the carrier cylinders 2032 distributed in a ring array are sequentially aligned with the spraying assembly 204. The carrier component 203 is connected to the carrier cylinders 2032 through the water tank 2031 to achieve liquid replenishment, and the flow-blocking ball 2034 in the connector 2033 ensures the seal in the non-connected state. This embodiment establishes a power transmission and intermittent positioning mechanism for the device, providing a basic framework for the orderly processing of multiple liquids.

[0049] Example 2

[0050] Please refer to Figures 1-8 This embodiment is basically the same as embodiment 1. This embodiment is made on the basis of embodiment 1 and has the same beneficial effects as embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0051] The spraying assembly 204 is used for stirring, transferring and spraying liquids. The spraying assembly 204 includes a mixing tank 2043 that slides on the inner wall of the mounting box 207, a docking assembly on the mixing tank 2043, and a stirring assembly for stirring and mixing the liquid in the mixing tank 2043. The bottom end of the mixing tank 2043 is connected to a spraying hose 2044.

[0052] The docking assembly includes a mating part 2041 threaded onto a bidirectional lead screw 2026, which is fixedly connected to a mixing tank 2043. A sealing cylinder 2042 passes through the mating part 2041 and communicates with the mixing tank 2043. A pin 2046 fixed inside the sealing cylinder 2042 has uniformly spaced through holes on its outer periphery and a spherical groove 2047 at its top for receiving a flow-blocking ball 2034. When the bidirectional lead screw 2026 rotates, it drives the mating part 2041 and the mixing tank 2043 to perform reciprocating lifting and lowering movements. When the mixing tank 2043 rises to a preset position, the sealing cylinder 2042 mates with the connector 2033 of the bearing cylinder 2032, the pin 2046 pushes open the flow-blocking ball 2034, and the liquid in the bearing cylinder 2032 flows into the mixing tank 2043 through the through holes on the outer periphery of the pin 2046.

[0053] Furthermore, the rotation of the bidirectional lead screw 2026 converts the rotational motion into reciprocating linear motion of the mating parts 2041 and the mixing tank 2043 along the height direction of the bidirectional lead screw 2026, thereby achieving the docking of the sealing cylinder 2042 and the bearing cylinder 2032. The ejector pin 2046 is used to push open the flow-blocking ball 2034 when docking with the connector 2033, providing a channel for liquid transfer.

[0054] The stirring assembly includes a connector 2061 fixed on the drive shaft of motor 2045. Multiple gears 2062 are symmetrically rotatably provided on the connector 2061. The multiple gears 2062 mesh with each other in pairs. The gears 2062 include, but are not limited to, three gears.

[0055] A connecting shaft 2064 is fixed at the center of gear 3 2062, and multiple stirring blades 2065 are sleeved on the outer wall of the connecting shaft 2064. The stirring blades 2065 on adjacent connecting shafts 2064 are distributed in a crisscross pattern. A limiting plate 2063 is fixedly provided in the mixing box 2043. An annular groove 2068 is provided on the limiting plate 2063. The connecting shaft 2064 located in the middle position is rotatably connected to the limiting plate 2063, and the connecting shafts 2064 located on both sides are slidably connected to the limiting plate 2063 through the annular groove 2068.

[0056] When motor 2045 starts, it drives connector 2061 to rotate. Gears 2062 on connector 2061 mesh and rotate in pairs, causing connecting shaft 2064 and stirring blades 2065 to stir the liquid in mixing tank 2043. The power of motor 2045 is transmitted to gears 2062 through connector 2061. The meshing transmission of gears 2062 causes connecting shaft 2064 to drive stirring blades 2065 to rotate, so as to fully stir the liquid and ensure the uniformity of the liquid.

[0057] Furthermore, while the two connecting shafts 2064 on both sides are driven to rotate by the gear 2062, they slide along the annular groove 2068 on the limiting disk 2063. The axis of the annular groove 2068 is the axis of the limiting disk 2063. As a result, the stirring blades 2065 on the two connecting shafts 2064 on both sides revolve while rotating, while the stirring blades 2065 on the central connecting shaft 2064 only rotate. Because the adjacent stirring blades 2065 are staggered, the liquid in the mixing box 2043 is turbulent when the motor 2045 rotates, thus achieving thorough mixing.

[0058] In summary, the docking assembly drives the mating component 2041 via the bidirectional lead screw 2026, causing the mixing tank 2043 to reciprocate and rise, ensuring precise docking of the joint 2033 between the sealing cylinder 2042 and the supporting cylinder 2032. The ejector pin 2046 pushes open the flow-blocking ball 2034, allowing liquid to be introduced through the through hole. The stirring assembly uses motor 2045 to drive the connecting component 2061, which is then meshed with gear 2062. This causes the middle connecting shaft 2064 to rotate, and the two side connecting shafts 2064 to slide and revolve along the annular groove 2068 of the limiting plate 2063. Combined with the staggered stirring blades 2065, this creates turbulence, ensuring thorough mixing of the liquid. This embodiment improves the liquid transfer path and stirring mechanism from the supporting cylinder 2032 to the mixing tank 2043. Combined with the intermittent positioning of Embodiment 1, it forms a complete workflow of liquid storage-intermittent transfer-stirring and mixing-spraying execution, providing a concrete implementation method for the device's spraying and cleaning functions.
