Description

Technical Field

[0001] This utility model relates to the field of grape processing technology, specifically to a pre-treatment device for young grapes. Background Technology

[0002] In the grape processing industry, pretreatment of young grapes is a crucial step in ensuring product quality and food safety, involving core processes such as washing and decontamination. Traditional processing methods rely heavily on manual labor or simple machinery. However, with the increasing scale of the industry, the requirements for processing efficiency, thorough cleaning, and ease of operation are constantly rising, necessitating the improvement of the pretreatment process through structural optimization and technological innovation.

[0003] Common grape pretreatment devices have certain limitations in their structural design. Some devices only use a fixed screen plate with a single spray structure. During the rinsing process, grapes tend to pile up and form obstructed areas, resulting in uneven water coverage of the fruit surface. This is particularly effective at removing dust, impurities, and residual dirt from skin folds. Furthermore, the lack of an effective vibration and turning mechanism results in insufficient collision force between the grapes and the screen, making it difficult to physically remove stubborn stains. Additionally, the screen plate has poor drainage, allowing impurities to easily re-adhere to the fruit surface with the water flow, causing secondary pollution. These devices fail to meet the requirements of grape processing. Therefore, a pretreatment device for young grapes is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pretreatment device for young grapes, which solves the technical problem that when using a fixed sieve plate with a single spray structure, grapes tend to pile up and form obstructed areas during the rinsing process, resulting in water flow not being able to evenly cover the surface of the fruit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for young grapes, comprising:

[0006] A platform, with a mounting bracket connected to its side, a first motor mounted on the back of the mounting bracket, a spraying mechanism mounted on the back of the platform, and a spraying frame mounted on the top of the platform.

[0007] A cam is coaxially connected to the outer end of the rotor of the first motor. A transmission rod is connected to the outside of the cam through a bearing. The outer end of the transmission rod is connected to the corresponding position on the outside of the spray frame through a bearing.

[0008] A screen is inserted into the lower inner cavity of the spray frame. The edges of the screen holes protrude upwards. The protruding design gives the screen holes a certain scraping and friction effect, which can scrape and polish the surface of the young grapes, thus abrading the surface of the young grapes and preventing the cuticle layer of the young grape skin from affecting the later processing. A connecting frame is installed on the outer side of the spray frame. A bearing column is installed on the outer side of the connecting frame facing the spray frame. A rotating frame is inserted inside the bearing column.

[0009] Flip-plates are installed on both sides of the outer side of the rotating frame, and a second motor is installed on the outer side of the connecting frame at a position corresponding to the support column.

[0010] Preferably, the bottom of the spray frame is through-hole, and a hopper is installed on the outer side of the spray frame, with the interior of the hopper connected to the interior of the spray frame. An insert plate is inserted into the interior of the hopper to facilitate material feeding.

[0011] Preferably, the platform has sliding grooves on both sides inside, and the bottom four corners of the spray frame are connected to pulleys. The pulleys are inserted into the sliding grooves, and the addition of pulleys and sliding grooves improves the smoothness of the spray frame's movement.

[0012] Preferably, the outer end of the rotating frame is coaxially connected to the outer end of the rotor of the second motor, the rotating frame is Y-shaped, and the flip plate is rake-shaped, which facilitates flipping the grapes.

[0013] Preferably, the outlet of the spraying mechanism is equipped with high-pressure nozzles, and the number of high-pressure nozzles is 12-24 sets. The spraying direction of the high-pressure nozzles is inclined to the moving trajectory of the spray frame, which improves the quality of spraying and rinsing.

[0014] Preferably, the surface of the screen is provided with evenly distributed hemispherical protrusions, and the edge of the screen is connected to the inner wall of the spray frame by elastic buckles, which facilitates the maintenance and replacement of the screen.

[0015] Compared with the prior art, the present invention provides a pretreatment device for young grapes, which has the following beneficial effects:

[0016] This grape pretreatment device uses a first motor to drive the rotation of a cam, which in turn drives the spray frame to reciprocate left and right via a transmission rod. Simultaneously, a second motor drives the rotation of a rotating frame and a flipping plate. This allows the grapes to roll and tumble while being rinsed inside the spray frame, ensuring that all surfaces of the grapes are fully exposed to the spray. This effectively avoids dead corners caused by overlapping grapes, ensuring the rinsing liquid evenly covers the fruit surface, improving the thoroughness of the cleaning. It more comprehensively removes dust, impurities, and residual dirt adhering to the grape skin. Furthermore, the vibration and tumbling cause regular collisions between grapes and between grapes and the screen, physically removing stubborn stains and using the screen structure to quickly separate impurities from the water flow, preventing secondary contamination. The upward-protruding screen design also scrapes and polishes the surface of the grapes, preventing the cuticle layer of the grape skin from affecting later processing, thus improving the ease of use and practicality of the grape pretreatment device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution: a pretreatment device for young grapes, comprising a platform 1, a mounting frame 2, a first motor 3, a spraying mechanism 4, a spraying frame 5, a cam 6, a transmission rod 7, a connecting frame 8, a bearing column 9, a screen 10, a rotating frame 11, a flip plate 12, a second motor 13, a hopper 14, an insert plate 15, a chute 16, and a pulley 17.

[0025] Please see Figure 1 A mounting bracket 2 is connected to the side of the platform 1. A first motor 3 is mounted on the back of the mounting bracket 2. A spraying mechanism 4 is mounted on the back of the platform 1. A spraying frame 5 is mounted on the top of the platform 1. The bottom of the spraying frame 5 is through-hole. Please refer to [link / reference]. Figure 4 A hopper 14 is installed on one side of the outer side of the spray frame 5, and the interior of the hopper 14 is connected to the interior of the spray frame 5. An insert plate 15 is inserted into the interior of the hopper 14. Slide grooves 16 are opened on both sides of the interior of the frame 1. Please refer to Figure 3 Each of the four bottom corners of the spray frame 5 is connected to a pulley 17, which is inserted into the inside of the slide groove 16. The outlet of the spray mechanism 4 is equipped with a high-pressure nozzle, and the number of high-pressure nozzles is 12-24. The spray direction of the high-pressure nozzles is inclined to the moving trajectory of the spray frame 5.

[0026] Please see Figure 2 Cam 6 is coaxially connected to the outer end of the rotor of the first motor 3. A transmission rod 7 is connected to the outside of cam 6 through a bearing. The outer end of transmission rod 7 is connected to the corresponding position on the outside of spray frame 5 through a bearing.

[0027] Please see Figure 3 The screen 10 is inserted into the lower part of the inner cavity of the spray frame 5. The connecting bracket 8 is installed on the outer side of the spray frame 5. Please refer to [link / reference]. Figure 4 and Figure 5 A bearing column 9 is installed on the outside of the connecting frame 8 facing the spray frame 5. A rotating frame 11 is inserted inside the bearing column 9. The surface of the screen 10 is equipped with evenly distributed hemispherical protrusions. The edges of the screen holes of the screen 10 protrude upwards. The protrusion design gives the screen holes a certain scraping and friction effect, which can scrape and polish the surface of the young grapes. It has the function of abrading the surface of the young grapes and avoids the cuticle layer of the young grape skin from affecting the later processing. The edge of the screen 10 is connected to the inner wall of the spray frame 5 by elastic buckles.

[0028] Flip plates 12 are installed on both sides of the outer side of the rotating frame 11. A second motor 13 is installed on the outer side of the connecting frame 8, corresponding to the bearing column 9. The first motor 3 drives the rotation of the cam 6, which in turn drives the spray frame 5 to reciprocate left and right via the transmission rod 7. Simultaneously, the second motor 13 drives the rotation of the rotating frame 11 and the flip plates 12. This allows the grapes to roll and turn when the spraying mechanism 4 washes the young grapes inside the spray frame 5, ensuring that all surfaces of the young grapes are fully exposed to the spray, effectively avoiding the blind spots caused by the stacking of grapes. The rinsing solution can evenly cover the surface of the fruit, greatly improving the thoroughness of the cleaning. It can more comprehensively remove dust, impurities and residual dirt attached to the fruit skin. The vibration and tumbling cause regular collisions between grapes and between grapes and screen 10, which not only removes stubborn stains through physical action, but also uses the screen hole structure to achieve rapid separation of impurities and water flow, avoiding secondary pollution. This improves the ease of use and practicality of the grape pretreatment device. The outer end of the rotating frame 11 is coaxially connected to the outer end of the rotor of the second motor 13. The rotating frame 11 is Y-shaped, and the flip plate 12 is rake-shaped.

[0029] This solution uses a first motor 3 to drive the rotation of the cam 6, which in turn drives the spray frame 5 to reciprocate left and right via the transmission rod 7. Simultaneously, a second motor 13 drives the rotation of the rotating frame 11 and the flip plate 12. This allows the grapes to roll and turn while the spray mechanism 4 is rinsing the young grapes inside the spray frame 5, ensuring that all surfaces of the young grapes are fully exposed within the spray range. This effectively avoids the dead corners formed by the stacking of grapes and ensures that the rinsing liquid can evenly cover the surface of the fruit, greatly improving the thoroughness of the cleaning. It can more comprehensively remove dust, impurities, and residual dirt attached to the grape skin. Furthermore, the vibration and turning cause regular collisions between grapes and between grapes and the screen 10, which not only physically removes stubborn stains but also utilizes the screen structure to quickly separate impurities from the water flow, avoiding secondary pollution and improving the ease of use and practicality of the grape pretreatment device.
