Throughout the accompanying drawings, the same elements are represented by the same or similar figure marks. Conventional structures or local structures will be omitted when they may cause confusion or difficulty in observing and understanding the understanding of the present disclosure. Unless otherwise specifically stated, the order and numerical values ​​of components and assembly steps set forth in the embodiments do not limit the scope of the present invention.

[0025] The utility model provides a flip-type cleaning device (hereinafter referred to as the device) which is particularly useful for cleaning a forage tray. The device mainly comprises a flip part 1, a base part 2, and a cleaning part 3. The flip mechanism can flip the tray 10 entering the cleaning part 3 from the upstream to face the front side (usually with the concave side as the working side, i.e., the front side) downwards, and the cleaning mechanism can be used to wash the front side from below, so that the tray cleaning and drainage functions can be automatically completed. After the flipping, cleaning and drainage are completed, the tray is flipped in the opposite direction and the tray is straightened. The tray 10 sent downstream can be connected to the sowing equipment later, so as to realize the integration of cleaning and sowing, and increase the efficiency of forage production. At the same time, the modular design makes it simple, reliable and easy to maintain.

[0026] The base portion 2 includes: a base 21, four supporting wheels 22 distributed at the four corners above the base 21, a driving motor 23, a passive sprocket 26 that cooperates with a transmission chain 24 described later to guide the transmission, a moving wheel 27 located at the bottom, and a water receiving box 28.

[0027] The turning part 1 includes: a first roller 11 and a second roller 12 which are opposite to each other and rollingly supported by two supporting wheels 22, respectively. The cable trough 15 for the chain-type electrical wiring 14 is preferably formed integrally with the first roller 11. Here, the second roller 12 is set as a driven wheel, and the first roller 11 is set as a driving wheel. Of course, it is not limited to this, and it can also be set as a structure in which the first roller 11 and the second roller 12 are formed integrally.

[0028] like Figure 4, 7 As shown in 7 , the annular drive chain 24 driven by the drive motor 23 passes through the driven sprocket 26 and winds around the outer peripheral groove 13 of the first rolling ring 11, thereby forming a flipping mechanism. While the first rolling ring 11 and the second rolling ring 12 roll relative to the support wheel 22, the cleaning unit 3 fixedly installed on the flipping part 1 can be flipped.

[0029] At a circumferential position above the outer peripheral groove 13, the two ends of the drive chain 24 are fixed in the outer peripheral groove 13 in such a way that the drive chain 24 covers, for example, more than half a circumference but less than a full circumference of the outer peripheral groove 13, whereby a 180-degree forward flip and a 180-degree return flip can be performed.

[0030] Specifically, the drive motor 23 installed on the base part 2 meshes with an intermediate position of the drive chain 24 away from the circumferential side of the outer peripheral groove 13 by means of a gear (such as a sprocket connected by a keyway) on the output shaft. Thus, when the drive motor 23 (a reversing motor) rotates bidirectionally back and forth, the drive chain 24 can drive the tray 10 in the cleaning unit 3 to rotate 180 degrees via the driven sprocket 26, turning the tray 10 face down and then resetting it.

[0031] As Figure 5 shown in Figure 5 , the cleaning unit 3 is integrally and fixedly connected between the first rolling ring 11 and the second rolling ring 12. The internal space of the cleaning unit 3 opens towards the upstream side and the downstream side respectively, and is internally provided with: a conveying part in the form of, for example, a double-speed chain 40 to receive the tray 10 conveyed from the upstream side; a limit switch 32 triggered when the tray 10 reaches a predetermined position; a stopping mechanism that locks the tray 10 in place when the limit switch 32 is triggered. The stopping mechanism may include, for example, claws (not shown) respectively clamped in different positions by the drive of the first cylinder and / or an anti-detachment bracket 41 that supports the tray 10 when the tray 10 is flipped, and a blocking cylinder 42 that rises upstream and downstream at a predetermined position to act as a barrier; a cleaning mechanism 34 that flushes the front of the tray 10 when the cleaning unit 3 is driven by the flipping mechanism to rotate, for example, 180 degrees to turn the tray 10 face down. The cleaning mechanism 34 includes a second cylinder 35 and a nozzle unit 36 driven by the second cylinder 35 to slide along the guide rail 39. The nozzle unit 36 includes, for example, a water pipe and a plurality of sector nozzles 361 spaced and communicated with the water pipe; a drainage housing 37 opposite to the front of the fixed tray 10; and an auxiliary support wheel 38 for transitively conveying the tray 10 after the flushing is completed on the downstream side.

[0032] As Figure 3As shown, a waterproof conveyor motor 311 and a conveyor gear 322 for driving a double-speed chain 40 are shown. Preferably, when the tray 10 is flipped so that its front side faces downward, the nozzle 361 of the nozzle unit 36 faces upward to wash the front side of the tray 10, and then the wastewater falls by gravity, is collected by the drainage housing 37, and is discharged from the bottom. However, it is not limited to this, and of course, it can also be set to perform cleaning in an inclined position. As Figure 2 shown, the drainage housing 37 includes, for example, a frustum-shaped water collection plate 371 and a water retaining plate 372 hermetically connected to the water collection plate 371.

[0033] As Figure 9 shown, the tray 10 is conveyed from the upstream front-side assembly line, is placed on the double-speed chain 40 in the cleaning unit 3, and continues to move forward. On this upstream side, a second cleaning nozzle (not shown) for flushing the lower side (bottom surface) of the tray 10 before it enters the cleaning unit 3 can also be additionally provided, thereby further preventing contamination caused by the bottom surface side.

[0034] As Figure 6 、 10 shown, when the tray 10 is conveyed by the double-speed chain 40 to a predetermined position, it hits and triggers the limit switch 32. Accordingly, the waterproof conveyor motor 311 stops driving the double-speed chain 40, and the blocking cylinders 42 on both the upstream and downstream sides rise to prevent the tray 10 from shifting.

[0035] As Figure 4 shown, the drive motor 23 drives the drive chain 24 to drive the flipping unit 1 to flip 180°, and automatically stops after reaching the position. At this time, the drain port 373 of the cleaning unit 3 rotates to the lower side of the tray 10 and faces the water receiving box 28 below. At this time, the anti-detachment bracket 41 abuts against and supports the tray 10.

[0036] As Figure 5 shown, the second cylinder 35 drives the water pipe to perform a scanning spray wash on the front side of the tray 10 by means of a plurality of nozzles 361, and the wastewater falls into the drainage housing 37 by its own weight and is discharged from the drain port 373 at the bottom.

[0037] Then, by using the reverse rotation of the drive motor 23, the tray 10 is reset to face upward, and then is transferred to the downstream side via the auxiliary idler 38 for subsequent operations, as Figure 11 shown.

[0038] According to the present utility model, it has the following advantages: First, the device reverses the tray 10 and then conducts cleaning. Sewage will not fall into the tray 10, featuring thorough cleaning and no secondary pollution. After reversing, the device can automatically drain water by gravity without the need for other devices, and has the characteristics of reliable structure and not being easily damaged. By means of moving the spray head, the device can completely cover the entire surface of the tray 10 without dead angles, featuring thorough cleaning. At the same time, the method of moving the spray head can reduce the number of spray heads, resulting in greater pressure for a single spray head and enabling the cleaning of stubborn stains. The device can automatically clean according to the amount of dirt on the surface of the tray 10. If there is a lot of dirt, the spray head moves back and forth multiple times; if there is little dirt, it is cleaned once to achieve the dual goals of cleaning effect and water conservation. The device can also be added with visual and other devices to achieve the cleaning of a single cross-section (single-row position) on the surface of the tray 10.

[0039] In addition, as the transmission and conveyor parts, they are not limited to the above-mentioned transmission chain and double-speed chain 40, and other transmission belts, roller paths, etc. can also be correspondingly adopted.

[0040] In the description of the present application, the meaning of "a plurality of" is two or more than two, unless otherwise specifically defined. Unless otherwise clearly stipulated and limited, terms such as "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. Although the present utility model has been described with reference to various specific embodiments, it should be understood that modifications can be made within the spirit and scope of the described inventive concept. Therefore, it is intended that the present utility model is not limited to the described embodiments, but will have the full scope defined by the language of the appended claims.
