Abstract
Description
Technical Field
[0001] This application relates to the field of vegetable transport machine technology, and in particular to a vegetable transport machine with an adjustable clamping limit plate. Background Technology
[0002] Existing vegetable conveyors have fixed limit plates on both sides of the transport channel to prevent vegetables from falling out. However, vegetables are not industrially standardized products and vary in size. This means that if the vegetables on the transport channel are too large and exceed the distance between the limit plates, they cannot pass through. Since the transport channel is usually of a fixed size, if a large distance is set between the limit plates, a gap will exist between the transport channel (e.g., the conveyor belt) and the limit plates, allowing smaller vegetables to fall out. Therefore, current technology lacks a means to adjust the distance between the limit plates according to the size of the vegetables. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below. An embodiment of this application discloses a vegetable conveyor with adjustable clamping and limiting plates, including a main support 1. The main support 1 has a transport channel 2 for transporting vegetables. The transport channel 2 is typically equipped with a conveyor belt or other transport device. Limiting plates 401 are provided on both sides of the transport channel 2 to prevent vegetables on the conveyor belt from detaching from the conveyor belt. The gap between the two limiting plates 401 is used for the vegetables transported by the conveyor belt to pass through.
[0019] The main support 1 is connected to an auxiliary support 3, which is located below the transport channel 2 to avoid obstructing the vegetables on the transport channel 2. The extension direction of the auxiliary support 3 is perpendicular to the extension direction of the transport channel 2. Both limiting plates 401 are connected to limiting supports 4, which are slidably connected to the auxiliary support 3. By sliding the two limiting supports 4 relative to the auxiliary support 3, the distance between the two limiting plates 401 changes, thereby accommodating vegetables of different sizes.
[0020] Furthermore, the sliding connection can be achieved using a clearance fit. For example, the auxiliary bracket 3 is provided with a guide rod, the extension direction of which is perpendicular to the extension direction of the transport channel 2. Both limiting brackets 4 have through holes, through which the guide rod passes. The position of the limiting bracket 4 relative to the guide rod can be changed by directly moving the limiting bracket 4. To ensure that the two limiting plates 401 can be relatively fixed in position relative to the auxiliary bracket 3, the sliding connection between the two limiting plates 401 and the auxiliary bracket 3 further enhances the limiting function. In this embodiment, two implementation methods are provided.
[0021] Firstly, the auxiliary bracket 3 is rotatably connected to a threaded rod 301, the extension direction of which is the same as that of the auxiliary bracket 3. Both limiting brackets 4 are provided with threaded holes, and the threads in the threaded holes of the two limiting brackets 4 are opposite. Both limiting brackets 4 are connected to the threaded rod 301 of the limiting bracket 4 through the threaded holes. Based on the opposite threads in the threaded holes of the two limiting brackets 4, by rotating the threaded rod 301, the two limiting brackets 4 will inevitably translate in opposite directions along the extension direction of the threaded rod 301, thereby expanding or decreasing the distance between the limiting plates 401; it can also simultaneously push the two limiting brackets 4 closer or further apart. Based on the rotatable connection between the threaded rod 301 and the auxiliary bracket 3, the threaded rod 301 itself rotates as the two limiting brackets 4 move closer or further apart.
[0022] Secondly, the auxiliary support 3 is rotatably connected to a threaded rod 301. The extension direction of the threaded rod 301 is the same as that of the auxiliary support 3. The threads on both sides of the threaded rod 301 are opposite in direction with the center line of the extension direction of the transport channel 2 as the center point. Both limiting supports 4 are provided with threaded holes, and both limiting supports 4 are connected to the threaded rod 301 of the auxiliary support 3 through the threaded holes. Based on the fact that the two completely opposite threads of the threaded rod 301 are connected to the threaded holes of the two limiting supports 4 respectively, the rotation of the threaded rod 301 makes the two limiting supports 4 move closer or further away from each other synchronously; at the same time, it actively pushes the two limiting supports 4, so that the two limiting supports 4 can also move closer or further away from each other synchronously when the threaded rod 301 is rotatably connected to the auxiliary support 3.
[0023] In both of the above scenarios, the threaded rod 301 is rotatably connected to the auxiliary bracket 3 via conventional bearing technology. The threaded rod 301 can also be connected to the main bracket 1 via bearings, clearance fits, or other methods, ensuring that the threaded rod 301 can rotate even when its position is fixed. Furthermore, the auxiliary bracket 3 can be equipped with an auxiliary support rod 302 as needed. The auxiliary support rod 302 is parallel to the threaded rod 301, and the limiting bracket 4 has an auxiliary support hole corresponding to the auxiliary support rod 302. The auxiliary support rod 302 and the auxiliary support hole have a clearance fit. This clearance fit between the auxiliary support rod 302 and the auxiliary support hole allows for a sliding connection between the limiting bracket 4 and the auxiliary bracket 3, which, along with the threaded connection between the threaded rod 301 of the auxiliary bracket 3 and the threaded hole of the limiting bracket 4, can coexist. This facilitates the use of the auxiliary support rod 302 to provide load-bearing support when the threaded rod 301 controls the movement of the limiting bracket 4.
[0024] Furthermore, both of the above situations require external force, especially human intervention, to actively change the distance between the two limiting plates 401. In this embodiment, a method for automatically changing the distance between the two limiting plates 401 is provided. A driven gear 303 is coaxially connected to the threaded rod 301. The driven gear 303 is located between the two limiting brackets 4. The main bracket 1 is equipped with a motor 5, and the rotating shaft of the motor 5 is equipped with a driving gear 501. The driving gear 501 and the driven gear 303 are connected by a chain 6. By driving the threaded rod 301 to rotate through the motor 5, regardless of which of the two connection methods is used, the two limiting brackets 4 will synchronously move closer or further apart under the rotation of the threaded rod 301.
[0025] Furthermore, since the transport channel 2 typically has a certain length, the limiting plates 401 on both sides of the transport channel 2 also have corresponding lengths. A single auxiliary bracket 3, regardless of its location within the transport channel 2, may not be sufficient to ensure stable changes in the distance between the two limiting plates 401. Therefore, in this embodiment, there are two auxiliary brackets 3, each connected to a corresponding limiting bracket 4. The two auxiliary brackets 3 are respectively positioned at the beginning and end of the transport channel 2, and the driven gears 303 of both auxiliary brackets 3 are connected to the driving gear 501 via the same chain 6. By providing auxiliary brackets 3 at both the beginning and end of the transport channel 2, the limiting brackets 4 on both sides of the transport channel 2 can be controlled simultaneously along both sides, thus making the limiting plates 401 on both sides of the transport channel 2 more stable when they approach or move away from each other.
[0026] Furthermore, the limiting plate 401 is located on both sides of the transport channel 2. Typically, the lowest point of the limiting plate 401 surface should be flush with the corresponding height of the upper surface of the transport channel 2. To stably control the limiting plate 401, the auxiliary bracket 3 should be positioned as close as possible to the upper surface of the transport channel 2. If the motor 5 is connected to one side of the transport channel 2, it will inevitably increase the space occupied by the entire equipment. Therefore, the motor 5 is located below the transport channel 2. The transport channel 2 is typically a conveyor belt, which has a certain thickness in its spatial structure. This means that the driving gear 501 corresponding to the rotating shaft of the motor 5 located below the transport channel 2 may not be at the same height as the driven gear 303 corresponding to the threaded rod 301 of the auxiliary bracket 3. Therefore, the main bracket 1 is equipped with a motor connecting frame 7. The motor 5 is connected to the motor connecting frame 7 and located below the transport channel 2. By setting the motor connecting frame 7, the connection position of the motor 5 is no longer restricted by the range of the main bracket 1, and thus the motor 5 is positioned below the transport channel 2 through the motor connecting frame 7. The motor connecting frame 7 is rotatably connected to two guide gears 8. The two guide gears 8 are located on the front and rear sides of the drive gear 501 respectively along the extension direction of the transport channel 2. The height of the two guide gears 8 is flush with the height of the driven gears 303 of the two auxiliary supports 3. By ensuring that the driven gears 303 of the two auxiliary supports 3 are at the same height through the guide gears 8, the drive gear 501, which is at the same height position, can still drive the driven gears 303 of the two auxiliary supports 3.
[0027] Working Principle: Based on the sliding connection between the limiting brackets 4 and the auxiliary brackets 3 on both sides of the transport channel 2, actively pushing the limiting brackets 4 changes their position relative to the auxiliary brackets 3, thereby changing the position of the limiting plates 401 connected to the limiting brackets 4 relative to the transport channel 2, resulting in the widening or narrowing of the gap between the limiting plates 401 on both sides of the transport channel 2. When the auxiliary bracket 3 is equipped with a threaded rod 301, rotating the threaded rod 301 synchronously changes the position of the limiting plates 401 on both sides of the transport channel 2 relative to the auxiliary bracket 3, thereby causing the limiting plates 401 on both sides of the transport channel 2 to move closer or further apart synchronously. The rotation of the threaded rod 301 can be actively controlled by a handle or similar means, or it can be electrically controlled by connecting a motor 5. When a motor 5 is provided, connecting the motor 5 to an external controller allows the external controller to control the forward and reverse rotation of the motor 5, thereby controlling the forward and reverse rotation of the threaded rod 301, thus enabling the limiting plates 401 on both sides of the transport channel 2 to move closer or further apart synchronously along its length.
