Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting equipment, and more particularly to a rope collection mechanism for vegetable stalk cutting equipment. Background Technology
[0002] When using vegetable stalk cutting equipment, bundles of vegetable stalks are typically loaded into the equipment through the feed inlet and then conveyed to the cutting machine via a conveyor belt. Vegetable stalks are usually bound with rope, and many vegetable stalks have a large amount of plastic bags (used for fruits like cucumbers, tomatoes, and peppers to help them grow stronger) wrapped around their branches or vines. Therefore, after cutting, the ropes or plastic bags need to be removed. This solution provides a rope collection mechanism for vegetable stalk cutting equipment. Utility Model Content
[0003] The purpose of this utility model is to provide a simple structure for collecting ropes in vegetable stalk cutting equipment.
[0004] This utility model is achieved through the following measures: The vegetable stalk cutting equipment includes a base, with a pair of support brackets 1 and 2 respectively arranged at the front and rear of the base. The base is provided with a discharge section, which includes a conveying mechanism for conveying the vegetable stalks cut by the cutter. The conveying mechanism includes a pair of inclined support rods respectively arranged on the support bracket 1 and inclined upward. A crossbar is provided between the top ends of the two inclined support rods, and a conveyor belt is provided between the two inclined support rods through a roller structure.
[0005] A rope collection mechanism for vegetable stalk cutting equipment is characterized by comprising a collection box disposed between the upper ends of a crossbar and a conveyor belt. A rotating shaft is disposed within the collection box. Specifically, the rotating shaft is disposed between two diagonal support rods via corresponding bearing seats and is driven by a corresponding motor. Several sets of rope-picking plates are disposed around the rotating shaft, evenly distributed along the axial direction of the rotating shaft. Any two rope-picking plates in the sets are staggered, and the sets are evenly distributed circumferentially. Several through slots are provided on the bottom plate of the collection box to cooperate with the rope-picking plates. When the rotating shaft rotates, the rope-picking plates pass through the through slots, picking up plastic strips or ropes into the collection box during rotation.
[0006] The specific features of this utility model also include: The rope collection mechanism also includes a fan mechanism, which includes a housing located at the rear end of the base. The housing has a pair of pipes that connect to the collection box. Inside the housing is a pair of fans that work in conjunction with the corresponding pipes. Under the action of the fans, the ropes entering the collection box are drawn into the pipes until they enter the housing.
[0007] The chassis includes a collection chamber with an internal cavity. A pair of through holes communicating with the collection chamber are provided on the upper surface of the chassis. A pair of fans are provided on the bottom surface of the collection chamber. The fans are provided with matching round pipes. The round pipes pass through the corresponding through holes and are coaxially arranged with the through holes. The pipes communicate with the corresponding through holes. A number of mesh holes are provided on the side of the round pipes that are directly opposite to the pipes. The mesh holes form a filter screen to prevent the wires from entering the round pipes.
[0008] A distributing mechanism is sleeved around the upper end of the circular tube. The distributing mechanism includes a circular top plate. A circular groove that mates with the circular tube is coaxially arranged on the lower side of the top plate. The upper end of the circular tube is movably inserted into the circular groove. A circular ring is coaxially arranged below the top plate. The circular ring is slidably sleeved around the outer side of the circular tube. A number of distributing plates are evenly arranged along the circumference between the outer side of the top plate and the outer side of the circular ring. The outer edge of the distributing plate slides against the inner wall of the through hole.
[0009] The distance between the outer edges of two adjacent dispensing plates is greater than the diameter of the pipe, so that the sucked-in rope will enter between the two adjacent dispensing plates. The distance between the inner edges of two adjacent dispensing plates is greater than the width of the filter screen. Below the filter screen, there is a receiving plate that slides against the lower side of the dispensing plate and is used to block the lower side of the two adjacent dispensing plates. The free end of the receiving plate is connected to the inner wall of the through hole, that is, after the rope is sucked into the through hole, it will fall on the receiving plate between the two adjacent dispensing plates.
[0010] An end cover covering the through hole is bolted to the upper side of the chassis. A stepper motor is mounted on the end cover. A fixed shaft is located at the center of the top plate. The upper end of the fixed shaft extends through the end cover and is mounted on the output shaft of the stepper motor. The unit angle of the stepper motor is the included angle between two adjacent dispensing plates. That is, for each pulse signal input, the stepper motor rotates by one unit angle. In this way, the rope will be driven to the side detached from the receiving plate by the rotation of the dispensing plates, and then fall into the collection chamber through the through hole. The collection chamber is equipped with a protective plate to protect the fan and prevent the rope that falls into the collection chamber from being sucked into the fan.
[0011] The beneficial effects of this utility model are as follows: By incorporating a specialized mechanical rope collection mechanism, the binding ropes and wrapped plastic strips mixed in with the vegetable stalks after cutting can be efficiently separated and automatically collected. These impurities are automatically intercepted and centrally processed in the post-cutting process, eliminating the need for manual sorting, significantly improving work efficiency and reducing labor intensity. Simultaneously, this design effectively prevents ropes and plastic strips from causing equipment entanglement and blockages in subsequent processing stages, ensuring the continuous and stable operation of the cutting equipment.

[0025] A distributing mechanism is sleeved around the upper end of the circular tube 15. The distributing mechanism includes a circular top plate 19. A circular groove that mates with the circular tube 15 is coaxially arranged on the lower side of the top plate 19. The upper end of the circular tube 15 is movably inserted into the circular groove.
