Description

Technical Field

[0001] The utility model relates to the technical field of tomato cleaning, and more specifically to a pre-cleaning device for tomato sorting. Background Art

[0002] Tomato sorting refers to the process of classifying and grading picked or purchased tomatoes. On the sorting line, workers will check the appearance of the tomatoes, mainly checking the color, shape, size and other characteristics of the appearance. Usually, tomatoes are divided into different grades, such as grade one, grade two and grade three, according to the completeness and quality of the appearance.

[0003] The pre-cleaning device for tomato sorting is usually used to perform preliminary cleaning on tomatoes before they enter the sorting line to remove larger impurities, dirt and residues on the surface, so as to reduce the workload of subsequent sorting links and improve sorting efficiency.

[0004] The existing pre-cleaning device generally uses a bubble cleaning machine in conjunction with a high-pressure flushing spray head to clean the surface of tomatoes. However, it is difficult to clean the stubborn dirt on the surface of tomatoes by relying solely on the bubble cleaning machine and the spray head, which will affect the appearance and taste of tomatoes, reduce the quality and market competitiveness of the product, and increase the workload of subsequent sorting and processing links. Summary of the invention

[0005] In order to overcome the above defects of the prior art, the utility model provides a pre-cleaning device for tomato sorting to solve the problems existing in the above background technology.

The water flow is driven by the circulating water pump 105, and the water flows through the left side of the bubble cleaning machine 1 through the circulating water pipe 103 into the right side of the bubble cleaning machine 1. Driven by the water flow, the tomatoes move from the right side to the left side. The filtering device 104 can filter impurities in the water. The transfer mechanism 2 is a common prior art, which transfers the preliminarily cleaned tomatoes to the surface of the brush cleaning component 3. The driving mechanism drives the roller 302 to rotate counterclockwise, so that the silicone brush 303 can clean the stubborn dirt attached to the surface of the tomato, and the side wall brush 403 can prevent the surface of the tomato from directly contacting the inner wall of the top frame 401. The push plate body 602 can touch and clean the tomato surface close to the inner wall of the top frame 401. Under the rotation of the drum 302, some tomatoes can be transmitted to the left, while some tomatoes slip and cannot be transmitted to the left. The cylinder 601 pushes the push plate body 602 to move downward, so that the bottom of the push plate body 602 is close to the top of the drum 302, and the starting motor 502 drives the cylindrical gear 503 to rotate counterclockwise. Through the meshing action with the rack plate 405, the fixed frame 501 is driven to move to the left along the outer side of the rack plate 405, and then the push plate body 602 pushes the tomatoes to be transmitted to the left. During the transmission and cleaning process of the tomatoes, the spray mechanism 402 sprays high-pressure water to clean the dirt on the surface of the tomatoes.

[0024] In a preferred embodiment, a circulating water pipe 103 is connected to both ends of the bubble cleaning machine 1, and a filtering device 104 and a circulating water pump 105 are respectively installed in the middle of the circulating water pipe 103.

[0025] In a preferred embodiment, a spray mechanism 402 is installed at the top of the inner side of the top frame 401, and the bottom of the front and back sides of the inner wall of the top frame 401 are fixedly connected with side wall brushes 403. The spray mechanism 402 can spray high-pressure water to flush the surface of the tomatoes, and the side wall brushes 403 rub against the surface of the tomatoes to clean the surface of the tomatoes.

[0026] In a preferred embodiment, the moving component 5 includes a fixed frame 501, a motor 502 is fixedly connected to the front of the fixed frame 501, a cylindrical gear 503 is fixedly sleeved on the outer side of the output shaft of the motor 502, and the cylindrical gear 503 is meshed with the top of the rack plate 405.

[0027] In a preferred embodiment, positioning grooves 451 are provided on the front, back and bottom of the rack plate 405, and a positioning block 504 is fixedly connected to the surface of the inner wall of the fixed frame 501. The positioning block 504 and the positioning groove 451 are adapted to each other. Through the cooperation of the positioning block 504 and the positioning groove 451, the fixed frame 501 can stably slide along the outer side of the rack plate 405.

[0028] In a preferred embodiment, the push plate assembly 6 includes a cylinder 601 fixedly connected to the bottom of the fixed frame 501, the piston end of the cylinder 601 is fixedly connected to the push plate body 602, the front and back sides of the top of the push plate body 602 are fixedly connected to the positioning rod 603, the top of the outer side of the positioning rod 603 is movably sleeved with a positioning tube 604, and the top of the positioning tube 604 is fixedly connected to the bottom of the fixed frame 501. When the cylinder 601 pushes the push plate body 602 to move downward, the moving assembly 5 drives the push plate assembly 6 to move to the left to promote the tomato transmission. When the cylinder 601 drives the push plate body 602 to move upward, the moving assembly 5 drives the push plate assembly 6 to move to the right for resetting.

[0029] Working principle of the utility model: the bubble cleaning machine 1 is a common prior art, which will not be described in detail in this application. The water flow is driven by the circulating water pump 105, and the water flows through the left side of the bubble cleaning machine 1 through the circulating water pipe 103 into the right side of the bubble cleaning machine 1. Driven by the water flow, the tomatoes move from the right side to the left side, and the filtering device 104 can filter the impurities in the water. The transfer mechanism 2 is a common prior art, which transfers the preliminarily cleaned tomatoes to the surface of the brush cleaning component 3, and the driving mechanism drives the roller 302 to rotate counterclockwise, so that the silicone brush 303 can clean the stubborn dirt attached to the surface of the tomato, and the side wall brush 403 can prevent the surface of the tomato from being in direct contact with the inner wall of the top frame 401. The push plate body 602 is in direct contact with the inner wall of the top frame 401, and can clean the surface of the tomatoes close to the inner wall of the top frame 401. Under the rotation of the drum 302, some tomatoes can be transmitted to the left, while some tomatoes slip and cannot be transmitted to the left.
