Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or partial structures will be omitted where they may cause confusion or make the understanding of the present disclosure difficult to observe. Unless otherwise specifically stated, the order and numerical values ​​of the components and assembly steps described in the embodiments do not limit the scope of this invention.

[0024] like Figure 1 As shown, this utility model provides a greenhouse cultivation trough cleaning machine, the overall structure of which mainly includes: a frame section 1, a wheel set section 2, a control box 3, a water tank section 4, and a spray section 5 (see...). Figure 8 ) and spray bar section 6.

[0025] like Figure 2 As shown, the cleaning machine can be used as a vehicle-type structural component. It travels along the track 78 using the wheel assembly 2 and uses cleaning media such as water from the water tank 4 to clean the corresponding surface of the zigzag groove 71 on the corresponding side (one side or both sides) via the spray bar 6.

[0026] Here, the Z-shaped groove 71 refers to a groove material with a Z-shaped cross-section. Z-shaped steel can be used as the skeleton material. It can be used as a cultivation trough or skeleton structure inside a greenhouse. For example, the Z-shaped cultivation trough is suitable for planting crops such as tomatoes. It has the characteristics of high trough strength, strong load-bearing capacity and large drainage capacity, which can improve production efficiency and output per unit area.

[0027] Figure 2 This example illustrates a scenario where two adjacent columns of slot 71 are being cleaned. In this case, as... Figure 3As shown, the top surfaces 34 of the two rows of zigzag grooves 71 and the opposing sidewalls 35 can be cleaned by the jet 33 of the spray bar 6, while the other sidewall 36 can be cleaned in the next working cycle of the cleaning machine or by another cleaning machine, similar to the sidewall 35.

[0028] More specifically, such as Figure 3 The tilt cleaning angle of the jet 33 shown can be adjusted by the adjustment mechanism. The top surface nozzle I 64 and the top surface nozzle II 68 can be used to clean the top surface 34 of the groove 71, respectively. The side wall nozzle I 69 and the side wall nozzle II 67 can be used to clean the side wall 35 on one side.

[0029] like Figure 4 The frame portion 1 shown includes a frame 11 and a frame housing 12. The frame housing 12 is connected to both ends of the frame 11, for example, in the form of a frame, and a corresponding wheel assembly 2 is installed at the lateral corner of each frame housing 12.

[0030] like Figure 5 As shown, each wheel assembly 2 includes: a track wheel 21 and a Mecanum wheel 22. The track wheel 21 and the Mecanum wheel 22 are integrated into a single structure, allowing the cleaning machine to travel on the track 78 as well as operate on ordinary, narrow ground surfaces. It is particularly suitable for greenhouse environments.

[0031] like Figure 6 As shown, the water tank section 4 is installed on the top of the frame 11 and includes: water tank 41, water tank bracket 42, water outlet 43 and water return 44.

[0032] like Figure 7 As shown, the spray boom 6 is fixedly mounted to the frame 11 via a column 60, and includes: spray booms I 61 and II 62 arranged separately on the column 60, a water-blocking bracket 63 to prevent water droplets from splashing, top surface nozzles I 64 and II 68 respectively arranged on both ends of the upper spray boom I 61, side wall nozzles I 69 and II 67 respectively arranged on both ends of the lower spray boom II 62, solenoid valves II 65 and I 66, and a water passage (not shown) for connecting the corresponding components. Each nozzle requires a certain pressure in the water passage to open. Each nozzle can swing relative to its corresponding spray bar I 61 and spray bar II 62. For example, it can be equipped with a swingable adjustment mechanism such as a ball head or a hinge. In this way, the top nozzles (top surface nozzle I 64 and top surface nozzle II 68) and the side nozzles (side wall nozzles I 69 and side wall nozzles II 67) arranged in two layers can be used to adjust the angle of each nozzle through the zigzag groove 71 corresponding to the side to be cleaned, so as to better clean the greenhouse cultivation trough located on the side of the frame part 1.

[0033] like Figure 8As shown, the spray unit 5 is fixedly installed in a spatial position below or above the frame 11, and includes: a water pump motor 51 (also known as an electric water pump), a multi-port connector in the form of a four-way connector 52, and a solenoid valve III 53.

[0034] In one embodiment, one end of the water pump motor 51's inlet can be connected to the water tank section 4's outlet 43 via a frame gap in the frame 11, and the other end's outlet is connected to a four-way connector 52. The remaining three connectors of the four-way connector 52 are respectively connected to solenoid valve III 53, solenoid valve II 65, and solenoid valve I 66. Solenoid valve III 53 is connected to the return water inlet 44 for, for example, returning water to the water tank 41 to depressurize the pipeline. Solenoid valve II 65 is connected to the top surface spray head II 68 and the side wall spray head II 67; solenoid valve I 66 is connected to the top surface spray head I 64 and the side wall spray head I 69, thereby allowing the cleaning on one side to be controlled separately using the control box 3.

[0035] like Figure 9 As shown, the cleaning process and pressure relief circuit are described in detail. First, the water pump motor 51 is turned on. The water pump motor 51 draws water from the outlet 43 of the water tank section 4 and supplies water to the four-way connector 52. At this time, solenoid valve III 53 is closed, and solenoid valve II 65 and solenoid valve I 66 are opened. At this time, each nozzle begins to clean the cultivation tank.

[0036] After the cultivation trough is cleaned, the water pump motor 51 is turned off. At this time, the residual water pressure inside each nozzle will cause water to drip from the nozzle. To relieve this pressure, the solenoid valve III 53 is opened, and the water in the water circuit returns to the water tank 4 through the return port 44. At this time, there will be no pressure in the water circuit, and the nozzles will close and stop dripping.

[0037] At both ends of the crossbeam 70 installed at the lower part of the column 60, or on the corresponding sides of the frame 11, the water-blocking brackets 63 are respectively installed on both sides of the side wall spray nozzles II 67 and I 69. That is, the two lower spray nozzles can be adjusted to extend into the water-blocking brackets 63. They can be made of two opposing rubber plates or long brushes. During the cleaning process, the brushes can prevent water from splashing and polluting the external environment.

[0038] According to this utility model, it has the following advantages: the chassis combines the track wheel 21 and the Mecanum wheel 22 into an integrated wheel set, which is suitable for operation in confined greenhouse spaces; the cleaning machine has a drip-proof function, and after the water pump motor 51 is turned off, the nozzles can be quickly shut off without dripping water by depressurization; the cleaning machine has a water-blocking device, and water-blocking devices are added to both sides of the top surface nozzle I64 to keep the environment clean during the cleaning process.

[0039] The above shows a multi-port connector in the form of a four-way connector 52, but it is not limited to this. For example, in a scenario where only one side is set, a three-way connector or a four-way connector with one closed port can be used. The outlet 43 of the water tank section 4 is connected to one port of the three-way connector via the water pump motor 51. The other port of the three-way connector is connected to the return water port 44 via the solenoid valve III 53 for return water pressure relief. The remaining port of the three-way connector is connected to the top nozzle and the side nozzle (corresponding to the top surface nozzle II 68 and the side wall nozzle II 67) via the cleaning solenoid valve (e.g., solenoid valve II 65) for cleaning the greenhouse cultivation trough located on the side of the frame section 1.

[0040] Thus, according to this utility model, a greenhouse, for example, in the form of a shed, can be provided, with a built-in track 78, and the aforementioned greenhouse cultivation trough cleaning machine and the zigzag grooves 71 arranged longitudinally along the track 78. The greenhouse cultivation trough cleaning machine can travel along the track 78 via the wheel assembly 2, and use the cleaning medium from the water tank 4 to clean the corresponding surface of the zigzag grooves 71 on the corresponding side via the spray bar 6.
