[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0035] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0036] Embodiment 1: This embodiment provides a melon picking and cleaning device, such as Figure 1 As shown, it comprises a cleaning tank 1 , a plurality of circular legs 2 distributed at equal angles are fixedly mounted on the bottom of the cleaning tank 1 , a feeding port 4 is provided on the top of the cleaning tank 1 , and the melons enter the cleaning tank 1 through the feeding port 4 .

[0037] like Figure 3 As shown, a wave separation member 5 is provided at the bottom of the cleaning tank 1, and the wave separation member 5 includes a dynamic sealing ring group 55, a docking ring 56 and a bottom tank 511. The bottom of the cleaning tank 1 is fixedly installed with the bottom tank 511, and the inner wall of the bottom tank 511 is slidably connected with the dynamic sealing ring group 55, and the docking ring 56 is fixedly installed at the bottom of the dynamic sealing ring group 55. The water used to wash the melons in the cleaning tank 1 is discharged by moving the dynamic sealing ring group 55 downward.

[0038] like Figure 5 and Figure 6 As shown, the interior of the bottom tank 511 is provided with a cleaning control component 6, including a blocking component, a weighing barrel 63, a supporting spring 66, a tooth plate 67, a gear shaft 68, an elliptical plate 69, and a hydraulic closure component. The inner wall of the bottom tank 511 is slidably connected to the weighing barrel 63, and the bottom of the weighing barrel 63 is elastically connected to the supporting spring 66 between the bottom of the bottom tank 511. The bottom of the weighing barrel 63 is fixedly connected to the tooth plate 67 through a straight rod. The side of the tooth plate 67 is meshed with the gear shaft 68. The end of the gear shaft 68 is fixedly installed with an elliptical plate 69. The arc surface of the elliptical plate 69 is in contact with the hydraulic closure component. A guide plate 616 is provided at the other end of the hydraulic closure component. The elliptical plate 69 can rotate at a maximum of one hundred and eighty degrees.

[0039] like Figures 7 to 9As shown, the hydraulic sealing member includes an extrusion plate 610, a hydraulic injector 611, a hydraulic push rod 612, a slide plate 613, a rotating gear 614 and a discharge door 615. The side of the extrusion plate 610 contacts the arc surface of the elliptical plate 69, and the other side of the extrusion plate 610 is fixedly connected to the hydraulic injector 611. The hydraulic injector 611 is fixedly connected to the hydraulic push rod 612 through a hydraulic damper. The end of the hydraulic push rod 612 is fixedly installed with a slide plate 613, which is meshed and connected with the rotating gear 614. The rotating gear 614 is fixedly connected to the discharge door 615 through a rotating shaft. The discharge door 615 is rotatably connected to the cleaning tank 1, the slide plate 613 slides on the outer wall of the cleaning tank 1, the side of the cleaning tank 1 is provided with a guide plate 616, and the discharge door 615 closes the guide plate 616.

[0040] The squeezing plate 610 is squeezed by the elliptical plate 69, and the hydraulic injector 611 and the hydraulic push rod 612 cooperate to deliver the hydraulic pressure to the slide plate 613, and the slide plate 613 moves to drive the rotating gear 614 to rotate, so that the discharge door 615 rotates to open the guide plate 616 and release the melon. The hydraulic damper reduces the hydraulic flow and has a delay effect, so as to prevent the discharge door 615 from opening when the water for washing the melon is injected into the weighing barrel 63, causing the melon and water to be discharged.

[0041] When washing the melons, the amount of water added to the washing tank 1 is fixed, so the weight of the water is fixed. The more dirt and impurities there are on the surface of the melons, the more dirt is contained in the water used to wash the melons, and the weight of the discharged water is large. The water used to wash the melons is weighed by the cooperation of the weighing bucket 63 and the support spring 66. The weight of the weighing bucket 63 and the water compresses the support spring 66. The weighing bucket 63 drives the gear shaft 68 to rotate by the tooth plate 67. The gear shaft 68 and the elliptical plate 69 rotate synchronously. The elliptical plate 69 squeezes the hydraulic sealing component, and the hydraulic sealing component is used to control the dredging and closing of the guide plate 616.

[0042] If the water used to wash the melons contains more dirt, the longer the downward movement distance of the weighing barrel 63 is, the greater the rotation angle of the elliptical plate 69 is; if the water used to wash the melons contains less dirt, the smaller the downward movement distance of the weighing barrel 63 is. The amount of water originally injected into the washing tank 1 can make the elliptical plate 69 rotate ninety degrees. The greater the squeezing force of the elliptical plate 69 on the hydraulic sealing member, if the total weight of the water and dirt entering the weighing barrel 63 is greater than the amount of water added to the washing tank 1, the weighing barrel 63 will move downward, driving the elliptical plate 69 to rotate by more than ninety degrees, and the guide plate 616 cannot be opened at this time.

[0043] A support plate 64 is fixedly installed on the inner wall of the bottom tank 511, and the bottom of the support spring 66 is fixedly connected to the support plate 64. The support plate 64 and the support spring 66 cooperate to support the weighing bucket 63. A plurality of water outlets are provided at the bottom of the weighing bucket 63, and a plurality of expansion openings 65 are provided on the support plate 64. The diameter of the expansion opening 65 is larger than the diameter of the water outlet. There is an expansion opening 65 below each water outlet, so as to facilitate the discharge of water in the weighing bucket 63 and prevent water from flowing at the support plate 64.

[0044] In this embodiment, the water used to wash the melons is weighed. If the water used to wash the melons contains more dirt, the longer the downward distance of the weighing barrel 63 is, and the greater the rotation angle of the elliptical plate 69 is; if the water used to wash the melons contains less dirt, the smaller the downward distance of the weighing barrel 63 is. When the weight of the water used to wash the fruits and melons is close to the weight of the water injected into the washing tank 1, the downward movement of the weighing barrel 63 can cause the rotation angle of the elliptical plate 69 to exceed ninety degrees. Under the action of hydraulic pressure, the discharge door 615 opens to discharge the cleaned fruits and melons in the washing tank 1.

[0045] Example 2: Based on Example 1, this example proposes a melon picking and cleaning device, such as Figure 2 As shown, the wave separation element 5 also includes a brush ring 51, a brush cylinder 52, a spiral guide rail 53 and a dynamic closed ring group 55. The inner wall of the cleaning tank 1 is fixedly installed with a multi-layer brush ring 51, the top of the cleaning tank 1 is fixedly installed with a motor 3, the bottom of the motor 3 is fixedly connected to the brush cylinder 52 through a rotating shaft, the melon is located between the brush cylinder 52 and the brush ring 51, the inner wall of the cleaning tank 1 is fixedly installed with a spiral guide rail 53, and the melon spirals into the interior of the cleaning tank 1 along the spiral guide rail 53.

[0046] The spiral guide rail 53 is used to separate the melons piled together, so that the melons enter the cleaning tank 1 in a spiral movement trajectory, so that the brush ring 51 and the brush cylinder 52 can clean the melons, while preventing the melons from directly blocking each other and affecting the cleaning. The brush cylinder 52 is driven by the motor 3 to rotate to clean the melon skin, and the rotation of the brush cylinder 52 drives the water flow inside the cleaning tank 1 to rotate.

[0047] like Figure 3 As shown, a fixed closed ring group 54 is fixedly installed on the inner wall of the bottom tank 511. The fixed closed ring group 54 includes a plurality of circular rings connected to each other, and there is a gap between two adjacent circular rings. The dynamic closed ring group 55 is complementary in shape to the fixed closed ring group 54. The dynamic closed ring group 55 and the fixed closed ring group 54 are combined to form a complete circular plate. When washing melons, the fixed closed ring group 54 and the dynamic closed ring group 55 are combined to separate the washing tank 1 and the bottom tank 511.

[0048] like Figure 4As shown, a missing gear 57 is fixedly installed at the bottom of the brush cylinder 52, and the bottom of the missing gear 57 is rotatably connected to the docking shaft 59. The top of the docking shaft 59 is fixedly installed with an inner ring tooth. The missing gear 57 is meshed and connected with the intermediate gear 58 through the inner ring tooth. A wave groove 510 is opened on the docking shaft 59, and the inner arc surface of the docking ring 56 is rollingly connected with two symmetrically arranged balls, and the balls roll in the wave groove 510.

[0049] By using the missing gear 57, the docking shaft 59 and the intermediate gear 58 to form a differential, after the brush cylinder 52 rotates to clean the melons several times, the docking ring 56 moves downward along the track of the wave slide 510, and the dynamic closed ring group 55 and the fixed closed ring group 54 are separated, so that the water in the cleaning tank 1 can enter the weighing bucket 63.

[0050] A telescopic rod 61 is fixedly installed at the bottom of the docking ring 56, and a closing plug 62 is fixedly installed at the bottom of the telescopic rod 61. The closing plug 62 blocks the water outlet at the bottom of the weighing bucket 63. When the docking ring 56 moves downward, the docking ring 56 uses the telescopic rod 61 to insert the closing plug 62 into the water outlet to close the weighing bucket 63. When the docking ring 56 moves upward along the track of the wave slide 510, the closing plug 62 and the weighing bucket 63 are separated to discharge the water for washing the melons.

[0051] In this embodiment, the missing gear 57, the docking shaft 59 and the intermediate gear 58 cooperate to form a differential, so that the docking ring 56 can periodically reciprocate up and down, and the dynamic closed ring group 55 and the fixed closed ring group 54 can be separated, so that the water in the cleaning tank 1 can enter the weighing bucket 63. At the same time, the melons above the fixed closed ring group 54 will move due to the change in the bottom support, and the water can be used to flush the melons to prevent soil between the melons from remaining on the melons.

[0052] Embodiment 3: Based on the above embodiment 1 or 2, this embodiment proposes a melon picking cleaning device, such as Figure 6 As shown, a recovery component 7 is provided inside the bottom tank 511, and the recovery component 7 includes a partition plate 71, a filter screen 72 and a coil spring 73. The partition plate 71 is fixedly mounted on the bottom inner wall of the bottom tank 511, and the top of the partition plate 71 is rotatably connected to the filter screen 72, and the coil spring 73 is elastically connected between the filter screen 72 and the partition plate 71.

[0053] The water used to wash the melons falls onto the coil spring 73, and the coil spring 73 rotates due to the impact force of the water. The coil spring 73 supports the filter screen 72 so that the filter screen 72 vibrates. The filter screen 72 separates the soil and water. Since the filter screen 72 is set inclined, the water slides along the filter screen 72 and washes the soil attached to the top of the filter screen 72 to the left end of the partition plate 71, thereby avoiding clogging of the filter screen 72 due to long-term filtering of soil.

[0054] A limit block 74 is fixedly installed on the inner wall of the bottom tank 511 and located on the rotation path of the filter screen 72. The top surface height of the limit block 74 is higher than the top surface height of the partition plate 71 to prevent the right end of the limit block 74 from being lower than the left end, causing water to flow to the right. The partition plate 71 divides the bottom tank 511 into two parts: a soil separation tank 75 and a recovery tank 76. The filter screen 72 is located directly above the soil separation tank 75. Extended leather is laid at the connection between the partition plate 71 and the filter screen 72. To prevent soil and water from flowing through the connection between the partition plate 71 and the filter screen 72, the water filtered by the coil spring 73 enters the soil separation tank 75, and the soil is washed into the recovery tank 76.

[0055] In the present embodiment, water used for washing the melons is filtered through the filter screen 72 for recycling and reuse, thereby avoiding wasting water resources. Under the cooperation of the impact force of the water and the elastic force of the coil spring 73, the filter screen 72 vibrates. When the filter screen 72 is blocked, the water flows along the filter screen 72 to flush the soil on the filter screen 72, thereby avoiding blockage of the filter screen 72 due to long-term filtration, which affects the recovery of water.

[0056] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
