Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to a tray mechanism for a sorter. Background Art

[0002] In modern agricultural production, sorters play a crucial role, especially when dealing with tuber crops such as potatoes and carrots. These machines can accurately classify crops according to physical characteristics such as size and weight to meet the diverse market demands for the quality of agricultural products. Among them, a key component - the tray mechanism - is responsible for accurately delivering the crops into the preset sorting channels to ensure the smooth progress of subsequent sorting processes.

[0003] However, the tray design in traditional sorters has certain limitations. Specifically, existing trays often need to cooperate with a side-turning mechanism to complete the crop dropping action, which requires occupying side space as the blanking space, increasing the floor area of the sorter.

[0004] Patent document CN218260622U discloses a tray mechanism for a sorter, in which a support frame, a tray, a connecting rod, and a rocker form a four-bar mechanism. When the tray reaches the highest point, the transmission angle of the mechanism is 0°, forming self-locking to ensure the stability of the objects to be sorted during transportation and prevent accidental dropping; by applying force to the trigger arm through an external trigger mechanism, the self-locking state is broken, and the connecting rod drives the rocker and the tray to rotate clockwise after being stressed, realizing the precise dumping of materials into the sorting channel below without the need for additional side space. Although it utilizes the self-locking and unlocking characteristics of the four-bar mechanism to achieve stable transportation and precise dumping of materials, it also has some obvious defects: (1) During the operation of the sorter, vibrations will inevitably occur, and the self-locking state of the four-bar mechanism is not stable under the influence of vibration factors and is easily broken under vibration, so the working reliability is not high; (2) The structure is complex. A four-bar mechanism needs to be set up for stepping, and a trigger component and a trigger mechanism also need to be set up, resulting in a high cost. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The purpose of the present invention is to provide a tray mechanism for a sorter to solve the problems existing in the above-mentioned prior art and improve the working reliability of the tray mechanism of the sorter.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0038] As Figures 1 to 4 shown, this embodiment provides a tray 2 mechanism for a sorter, including:

[0039] A support frame 1, and the support frame 1 is used to connect with the transmission mechanism of the sorter;

[0040] A tray assembly, the tray assembly includes a tray 2, and the tray 2 is hinged to the top end of the support frame 1 through a first hinge shaft 4;

[0041] A swing rod 6, the top end of the swing rod 6 is hinged to the tray 2 through a second hinge shaft 5, an overlapping block 8 is fixedly arranged on one side of the swing rod 6 close to the support frame 1, a fixed block 9 is fixedly arranged on one side of the support frame 1 close to the swing rod 6, the bottom surface of the overlapping block 8 is a plane, and the overlapping block 8 can overlap on the fixed block 9;

[0042] A tension spring 7, one end of the tension spring 7 is fixedly connected to the support frame 1 and the other end is fixedly connected to the swing rod 6, and the tension spring 7 is used to provide a pulling force for the swing rod 6 towards the support frame 1;

[0043] A trigger assembly, and the trigger assembly is used to drive the swing rod 6 to swing towards the side away from the support frame 1.

[0044] The specific working principle of the tray 2 mechanism for the sorter in this embodiment is as follows:

[0045] When the tray 2 is normally carrying materials, the swing rod 6 is subjected to a downward pressure. This pressure causes the latching block 8 on the swing rod 6 to latch onto the fixed block 9 on the support frame 1. At the same time, the tension spring 7 can provide a pulling force towards the support frame 1 for the swing rod 6, preventing the latching block 8 from separating from the fixed block 9 under vibration and ensuring that the latching block 8 can stably latch onto the fixed block 9, effectively improving the reliability of the operation of the sorting machine tray 2 mechanism.

[0046] When it is necessary to place materials, the trigger assembly is made to drive the swing rod 6 to swing towards the side away from the support frame 1, causing the latching block 8 to separate from the fixed block 9, and further enabling the tray 2 to rotate downward, thereby completing the placement of materials.

[0047] In an alternative embodiment of the present embodiment, preferably, the trigger assembly includes a first magnet and a second magnet fixedly arranged on the swing rod 6. A groove 10 is provided at the bottom end of the swing rod 6 corresponding to the second magnet, and the second magnet is fixedly arranged in the groove 10. The first magnet is arranged on the frame of the sorting machine or fixedly arranged on the support frame 1. The first magnet and the second magnet can repel each other. The output force of the trigger assembly is realized by the mutual repulsion between the first magnet and the second magnet, with a simple structure and low cost.

[0048] In the present embodiment, the following several alternative specific setting schemes for the first magnet and the second magnet are provided:

[0049] (1) The first magnet is an electromagnet and the second magnet is a permanent magnet. The first magnet can be arranged on the frame of the sorting machine or fixedly arranged on the support frame 1.

[0050] When the first magnet is arranged on the support frame 1, the first magnet is energized when it is necessary to place materials.

[0051] When the first magnet is arranged on the frame of the sorting machine, the first magnet can be continuously energized, so that when the support frame 1, the tray 2 and the swing rod 6 move to the placement station, the placement action can be stably realized with high reliability.

[0052] (2) The first magnet is a permanent magnet and the second magnet is an electromagnet. The first magnet can be arranged on the frame of the sorting machine or fixedly arranged on the support frame 1.

[0053] When the first magnet is arranged on the support frame 1, the second magnet is energized when it is necessary to place materials.

[0054] When the first magnet is arranged on the frame of the sorting machine, the second magnet can be continuously energized, so that when the support frame 1, the tray 2 and the swing rod 6 move to the placement station, the placement action can be stably realized with high reliability.

[0055] (3) Both the first magnet and the second magnet are electromagnets. The first magnet can be arranged on the frame of the sorting machine or fixedly arranged on the support frame 1.

[0056] When it is necessary to make a delivery, the first magnet and the second magnet are respectively energized.

[0057] (4) Both the first magnet and the second magnet are permanent magnets, but the first magnet must be arranged at the delivery station on the frame of the separator, so that when the support frame 1, the tray 2 and the swing rod 6 move to the delivery station, the delivery action can be stably realized, and the reliability is high.

[0058] It should be noted that, in addition to using the first magnet and the second magnet in this embodiment, the trigger assembly can also use other types of driving devices such as cylinders, hydraulic cylinders, linear motors, etc. to drive the swing rod 6 to swing towards the side away from the support frame 1.

[0059] In an alternative embodiment of the present embodiment, preferably, the top surface of the overlapping block 8 is the first inclined surface 12, and the end of the first inclined surface 12 away from the swing rod 6 is farther from the top end of the swing rod 6 than the other end of the first inclined surface 12; the bottom surface of the fixed block 9 is the second inclined surface 11, and the end of the second inclined surface 11 close to the swing rod 6 is closer to the top end of the support frame 1 than the other end of the second inclined surface 11. The design of the first inclined surface 12 on the overlapping block 8 and the second inclined surface 11 on the fixed block 9 can prevent the overlapping block 8 from not being reset due to the contact between the top surface of the overlapping block 8 and the bottom surface of the fixed block 9 during reset.

[0060] In an alternative embodiment of the present embodiment, preferably, the tray assembly further includes a connecting seat 3, the connecting seat 3 is fixedly connected to the tray 2, and the connecting seat 3 is hinged to the support frame 1 through a first hinge shaft 4; the top end of the swing rod 6 is hinged to the connecting seat 3 through a second hinge shaft 5.

[0061] In an alternative embodiment of the present embodiment, preferably, a reset assembly is further included. The reset assembly includes a reset block arranged at the reset station, and the top surface of the reset block is a reset guiding surface. When the tray 2 moves with the transmission mechanism of the separator, the tray 2 can rotate upward relative to the support frame 1 under the action of the reset guiding surface; the reset guiding surface can enable the tray 2 to rotate upward relative to the support frame 1, thereby increasing the height of the swing rod 6, and under the pulling action of the tension spring 7, the overlapping block 8 is re-abutted against the fixed block 9.

[0062] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
