Abstract
Description
Technical Field
[0001] This utility model relates to the field of tomato production and processing technology, specifically to a tomato processing reverse selection device. Background Technology
[0002] Tomatoes, also known as tomatoes, are a common annual herbaceous plant. The entire tomato plant is covered in soft hairs, and the flowers are yellow. Tomatoes are not particular about soil type, but they thrive best in loose, fertile, and well-drained soil, such as garden soil, sandy loam, or humus soil. The tomato production and processing typically includes several stages such as raw material handling, pretreatment, concentration, blending, filling, sterilization, and packaging. Among these stages, raw material handling is a crucial step, directly affecting the quality and efficiency of subsequent processing. A reverse-selection device is required in the raw material handling process for tomatoes.
[0003] A typical tomato processing reverse separation device usually consists of a screen drum, a frame, a feed inlet, a transmission system, and other components. The screen drum is first installed on the frame, and then the tomatoes to be screened are fed into the drum through the feed inlet. The transmission system drives the screen drum to rotate on the frame. The screen drum is designed with circular holes of different diameters to screen tomatoes of different sizes. Other components include belts, V-belt pulleys, bearings, bearing housings, and a separation mechanism.
[0004] Traditional tomato processing reverse selection devices use a rotating screen drum to drive the tomatoes, causing them to fall through corresponding holes on the drum's surface for reverse selection. During rotation, friction and collisions occur between the tomatoes and the drum wall, damaging the tomato skin and affecting their integrity and appearance. To address this issue, some tomato processing reverse selection devices use an inclined screening plate with evenly spaced screening holes of varying diameters. When tomatoes are placed on top of the screen and rolled, they fall through the corresponding holes, achieving a reverse selection effect and ensuring the integrity and appearance of the tomatoes during the process. However, this method lacks control over the rolling motion of the tomatoes on the screening plate, leading to a decrease in the reverse selection effect and quality, and requiring more manpower and resources for secondary screening. Therefore, a new tomato processing reverse selection device is proposed. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] In view of the shortcomings of the existing technology, this utility model provides a tomato processing reverse screening device to solve the above-mentioned technical problems that not only reduce the reverse screening effect and quality of tomatoes, but also require more manpower and material resources for secondary screening.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a tomato processing reverse selection device, comprising:
[0009] The device frame plate and the screening plate set on the top of the device frame plate, with screening holes evenly opened on the top of the screening plate, and protective side plates added to the front and rear ends of the top of the device frame plate.
[0010] A threaded screw is located on the upper outer side of the protective side plate, and the end of the threaded screw is coaxially connected to a first drive motor, and a sliding block is sleeved on the surface of the threaded screw.
[0011] An adjustable side plate is located on the inner side of the protective side plate and is connected to a sliding block. A buffer plate is added to the outer side of the adjustable side plate, and a buffer pad is connected to the outer side of the buffer plate. Buffer rods are evenly installed on the inner side of the buffer plate, and the ends of the buffer rods extend inward through the surface of the adjustable side plate and are connected to buffer springs. After the tomatoes are conveyed to the top of the device frame, the tomatoes first contact the buffer pad and buffer plate. The buffer plate drives the buffer rods into the adjustable side plate to compress the buffer springs. At the same time, the first drive motor drives the threaded screw to rotate on the protective side plate. The sliding block can drive the adjustable side plate to move along the top of the device frame according to the rotation of the threaded screw. The tomatoes can move cyclically along the top of the device frame, so that the tomatoes can fall into the external storage box according to the corresponding screening plate and screening holes. On the one hand, it can not only drive the tomatoes to circulate on the top of the device frame, thus ensuring the reverse selection effect and quality of the tomatoes, but also eliminate the need for a secondary reverse selection operation, thereby saving manpower and resources; on the other hand, the buffer mechanism can provide a buffering effect on the rolling tomatoes, thus ensuring the integrity and appearance quality of the tomatoes during the reverse selection process.
[0012] Preferably, a limiting plate is installed at the center of the front and back of the screening plate, and a limiting groove is formed on the inner wall of the device frame plate, with the limiting plate and the limiting groove corresponding in shape and position. The screening plate can be installed inside the limiting groove of the device frame plate through the limiting plate, which facilitates the replacement of the screening plate according to the size of different batches of tomatoes.
[0013] Preferably, a fixed base plate is installed at the front and rear ends of the bottom of the screening plate, and a limiting post is inserted into the bottom of the fixed base plate. The end of the limiting post passes through the device frame plate and the limiting groove and fits against the limiting plate. The limiting post can be moved along the fixed base plate so that the limiting post enters the limiting groove and pushes the limiting plate upward, thereby facilitating the replacement of the screening plate.
[0014] Preferably, a return spring is fitted onto the lower part of the surface of the limiting pin, and the ends of the return spring are tightly fitted to the surfaces of the fixed base plate and the limiting pin. When the limiting pin pushes the limiting plate upward, the limiting pin can be reset under the action of the return spring.
[0015] Preferably, a rotating shaft is provided at the center of the front and back of the device frame plate, and the rotating shaft is rotatably connected to the device frame plate. A second drive motor is coaxially connected to the end of the rotating shaft. The second drive motor drives the rotating shaft to rotate on the device frame plate, and the direction of rotation of the rotating shaft can be adjusted.
[0016] Preferably, the rotating shaft is connected to the protective side plate, and a separation pressure plate is installed on the front of the protective side plate, with the bottom end of the separation pressure plate corresponding to the bottom end of the limiting post. The rotating shaft can drive the protective side plate to rotate to the lower sides of the device frame plate, thereby separating the protective side plate from the limiting plate. The separation pressure plate can rotate in the same direction as the protective side plate, causing it to press upward against the limiting post. This not only ensures the stability of the connection between the screening plate and the device frame plate but also facilitates the automated removal of the screening plate.
[0017] (III) Beneficial Effects
[0018] Compared with the prior art, the present invention provides a tomato processing reverse selection device, which has the following beneficial effects:
[0019] This tomato processing reverse selection device works by conveying tomatoes to the top of the device frame. The tomatoes first contact a buffer pad and a buffer plate. The buffer plate then drives a buffer rod into an adjusting side plate, compressing a buffer spring. This buffer mechanism provides cushioning for the rolling tomatoes, ensuring their integrity and appearance quality during the reverse selection process. Simultaneously, a first drive motor drives a screw on the protective side plate to rotate. A sliding block, based on the screw's rotation, moves the adjusting side plate along the top of the device frame. The tomatoes circulate along this top, descending through corresponding screening plates and holes into an external collection box. This system not only ensures effective and high-quality reverse selection by circulating the tomatoes on the top of the device frame but also eliminates the need for a secondary reverse selection operation, saving manpower and resources.

[0026] This utility model provides a technical solution: a tomato processing reverse selection device, comprising: (see details) Figure 1 The device frame plate 1 and the screening plate 2 set on the top of the device frame plate 1, and the top of the screening plate 2 is evenly provided with screening holes 3, and protective side plates 9 are added to the front and rear ends of the top of the device frame plate 1.
[0027] Please see Figure 3 A threaded screw 10 is located on the upper outer side of the protective side plate 9, and the end of the threaded screw 10 is coaxially connected to a first drive motor 11, and a sliding block 12 is sleeved on the surface of the threaded screw 10.

[0029] Please see Figure 2 A limiting plate 4 is installed at the center of the front and back of the screening plate 2, and a limiting groove 5 is formed on the inner wall of the device frame plate 1. The limiting plate 4 and the limiting groove 5 correspond in shape and position. The screening plate 2 can be installed inside the limiting groove 5 of the device frame plate 1 through the limiting plate 4, which facilitates the replacement of the screening plate 2 according to the size of different batches of tomatoes. A fixed base plate 6 is installed at the front and rear ends of the bottom of the screening plate 2, and a limiting post 7 is inserted into the bottom of the fixed base plate 6. The end of the limiting post 7 passes through the device frame plate 1 and the limiting groove 5 and fits against the limiting plate 4. The limiting post 7 can be moved along the fixed base plate 6 so that the limiting post 7 enters the limiting groove 5 and pushes the limiting plate 4 upward, thereby facilitating the replacement of the screening plate 2. A return spring 8 is sleeved on the lower part of the surface of the limiting post 7, and the end of the return spring 8 is tightly fitted to the surface of the fixed base plate 6 and the limiting post 7, respectively.
