[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] like Figure 1 、 Figure 2 As shown, a vegetable washing device comprises a washing box 1 with an opening on the top, a feeding mechanism 2 is provided on the top of one side of the washing box 1, and a discharging port is provided on the other side, a first conveying mechanism 3 is provided inside the washing box 1, one end of which is located below the feeding mechanism 2, a second conveying mechanism 4 is provided below the end of the first conveying mechanism 3 away from the feeding mechanism 2, the first conveying mechanism 3 and the second conveying mechanism 4 are belt conveying devices, and the belts are mesh belts; a third conveying mechanism 5 is provided between the ends close to the first conveying mechanism 3 and the second conveying mechanism 4, in this embodiment, the first conveying mechanism 3 and the second conveying mechanism 4 are arranged horizontally, and a nozzle for washing vegetables is provided above them;

[0025] The end of the third conveying mechanism 5 close to the first conveying mechanism 3 is tilted downward, and the conveying direction of the third conveying mechanism 5 is obliquely upward. The higher end of the third conveying mechanism 5 is provided with an auxiliary rolling component 6, and the auxiliary rolling component 6 is used to generate a force on the top of the vegetables that is obliquely downward and parallel to the third conveying mechanism 5. The vegetables are transported from the first conveying mechanism 3 to the third conveying mechanism 5, and are rolled to the second conveying mechanism 4 under the coordinated action of the third conveying mechanism 5, the auxiliary rolling component 6 and gravity;

[0026] After the vegetables are transported by the first conveyor 3 and fall onto the third conveyor 5, the vegetables tend to move downward along the surface of the third conveyor 5 due to the influence of gravity due to the inclined setting of the third conveyor 5. When the inclination angle of the third conveyor 5 is appropriate, the vegetables will move downward to the second conveyor 4.

[0027] In order to facilitate the vegetables to move on the third transmission mechanism 5 in a rolling manner rather than sliding, whether to start the third transmission mechanism 5 is selected according to factors such as the shape of the vegetables;

[0028] If the vegetables are prone to rolling, the third conveying mechanism 5 can be stopped. After the vegetables fall onto the third conveying mechanism 5, the auxiliary rolling component 6 generates a downward force (b) on the top of the vegetables that is parallel to the conveying surface of the third conveying mechanism 5. The vegetables are acted upon by the auxiliary rolling component 6 and roll downward onto the second conveying mechanism 4.

[0029] If the vegetables are more likely to slide, the third transmission mechanism 5 is started. The transmission direction of the third transmission mechanism 5 is opposite to the movement direction of the vegetables. The third transmission mechanism 5 will generate an upward force a along the transmission surface on the bottom of the vegetables, and then generate an downward force b on the top of the vegetables through the auxiliary rolling component 6. The force a is parallel to the force b and in opposite directions and acts on the bottom and top of the vegetables respectively. The vegetables are more likely to roll due to the forces a and b. At the same time, the transmission speed of the third transmission mechanism 5 is controlled so as not to affect the rolling of the vegetables to the second transmission mechanism 4.

[0030] like Figure 3 、 Figure 4 As shown, specifically, the third transmission mechanism 5 includes two side plates 501 arranged in parallel in the cleaning box 1, two rollers 502 arranged in parallel and rotatably between the two side plates 501, and a transmission mesh belt 503 mounted on the two rollers 502. The two side plates 501 are parallel to the side walls of the cleaning box 1. The rotating shaft of one of the rollers 502 is connected to a driving assembly for driving the roller 502 to rotate. The auxiliary rolling component 6 located at the higher end thereof is connected between the two side plates 501.

[0031] In order to adjust the inclination angle of the third transmission mechanism 5 for different types of vegetables, a rotating shaft 504 located at the lower end is fixedly provided on one side of each side plate 501 close to the inner wall of the washing box 1. The two rotating shafts 504 are coaxially arranged, and the rotating shaft 504 is rotatably connected to the inner wall of the washing box 1. The ends of the two side plates 501 away from the rotating shaft 504 are connected to the inclination adjustment components 505 located therebelow. The inclination angle of the transmission mesh belt 503 can be changed by the inclination adjustment component 505. The inclination adjustment component 505 drives the end of the third transmission mechanism 5 away from the rotating shaft 504 to move, thereby changing the inclination angle of the third transmission mechanism 5;

[0032] Specifically, such as Figure 4 As shown, the rotating shaft 504 passes through the side plate 501 and is fixedly connected thereto, a cavity is coaxially provided inside the rotating shaft 504 and is coaxially arranged with the rotating roller 502 at the lower end, the rotating shaft of the rotating roller 502 at the lower end sequentially passes through the cavity and passes through the side wall of the cleaning box 1 to be transmission-connected to the driving assembly, the rotating shaft 504 is rotationally connected to the side wall of the cleaning box 1 through a rotating bearing, and the rotating shaft of the rotating roller 502 is located in the cavity and is coaxially rotationally connected to the rotating shaft 504 through a rotating bearing;

[0033] Specifically, such as Figure 3As shown, the tilt adjustment assembly 505 includes a first support plate 506 fixed inside the cleaning box 1 and located below the third transmission mechanism 5, a first telescopic cylinder 507 rotatably arranged on the first support plate 506, and a transmission plate 508 fixedly connected to the bottom of the two side plates 501. The telescopic rod of the first telescopic cylinder 507 faces the transmission plate 508 and is rotatably connected thereto;

[0034] Specifically, such as Figure 5 As shown, the auxiliary rolling component 6 includes a second support plate 601 fixedly connected to the bottom of the two side plates 501, and a plurality of nozzles 602 provided on the second support plate 601. The plurality of nozzles 602 are parallel to the conveyor mesh belt 503 and face toward its lower end.

[0035] In order to facilitate the adjustment of the distance between the nozzle 602 and the conveyor belt 503 to adapt to vegetables of different sizes and generate force on the top of the vegetables, a second telescopic cylinder 603 is fixedly provided on the side of the second support plate 601 close to the conveyor belt 503. The telescopic rod of the second telescopic cylinder 603 passes through the second support plate 601 and is fixedly connected to a movable plate 604, and the nozzle 602 is fixed on the movable plate 604.

[0036] Example 2:

[0037] In order to collect impurities washed off the vegetables, based on the first embodiment, a first collecting pool 7 for collecting sewage is provided at the bottom of the washing box 1. The bottom of the first collecting pool 7 is connected to a first sewage pipe 701. A second collecting pool 8 for collecting overflow sewage from the first collecting pool 7 is provided outside the first collecting pool 7. The overflow height of the second collecting pool 8 is smaller than that of the first collecting pool 7 and a second sewage pipe 801 is connected to the bottom thereof. The bottom of the washing box 1 is connected to a third sewage pipe 9.

[0038] The solid impurities washed off the vegetables are generally divided into those floating on the water surface and those sinking to the bottom. When the sewage from washing the vegetables falls into the first collecting tank 7, some impurities float on the water surface. As the sewage increases, the water level gradually rises above the height of the first collecting tank 7, and the impurities floating on the water surface overflow into the second collecting tank 8, while the vast majority of impurities that are easy to sink to the bottom remain in the first collecting tank 7, thereby achieving the purpose of classified collection of impurities.

[0039] In order to reduce the impact of the water flow and make the water flow slowly into the first collection tank 7, so as to facilitate the diversion of impurities, a plurality of evenly distributed slow-flow plates 10 are provided below the first transmission mechanism 3 and the second transmission mechanism 4. The falling sewage flows into the first collection tank 7 along the surface of the slow-flow plates 10;

[0040] In order to improve the circulation effect, the slow flow plate 10 is arranged at an angle and extends to the bottom of the first collection tank 7.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
