Description

Technical Field

[0001] This utility model relates to an agricultural harvesting device, specifically, a low-damage picking and conveying device for black sesame bundles. Background Technology

[0002] As an indeterminate inflorescence crop, black sesame flowers and bears fruit sequentially from bottom to top. The maturity time of the capsules is not uniform. Furthermore, no varieties of black sesame have been bred to resist grain loss or dwarf the plant. Therefore, when black sesame is harvested, there are immature capsules at the top containing many incompletely plump gray-black seeds, while there are cracked capsules at the bottom, in which the black sesame seeds are very easy to fall off.

[0003] Currently, black sesame harvesting relies heavily on manual, segmented harvesting. First, the sesame seeds are cut by hand, then bundled and dried. After drying, the bundles are manually picked up, turned over, and threshed by striking them with sticks. This process is typically repeated 2-3 times to complete threshing. During picking, because most of the sesame seed capsules have already cracked after drying, they must be handled with care. Existing black sesame bundle picking devices mostly have a spring-tooth structure, which exerts excessive impact on bundles prone to shedding, resulting in high loss and breakage rates. Furthermore, black sesame bundles are often piled in groups of three for drying at different angles, making the existing picking devices unstable and prone to knocking the bundles forward or sideways, affecting the success rate of picking. These problems are among the issues that urgently need to be addressed in the mechanized harvesting of black sesame. Utility Model Content

[0004] The purpose of this invention is to provide a low-loss picking and conveying device for black sesame bundles, so as to overcome the defects of existing black sesame bundle picking devices in terms of high loss rate and breakage rate of black sesame seeds and poor picking stability during the picking process.

[0005] This utility model is achieved using the following technical solution: A low-loss picking and conveying device for black sesame bundles includes a conveying mechanism and a picking mechanism installed at the front end of the conveying mechanism. The conveying mechanism includes a housing and a conveyor belt assembly. The conveyor belt assembly is inclinedly installed on the housing. The picking mechanism includes two feeding roller assemblies symmetrically arranged on both sides of the front end of the housing. Each feeding roller assembly includes a connecting bracket, a motor mounting base, a hydraulic motor, an upper bearing seat, a spiral feeding roller, a lower bearing seat, and a conical head. The connecting bracket is fixedly connected to the side of the housing. The motor mounting base and the lower bearing seat are fixedly connected to the upper and lower ends of the connecting bracket, respectively. The hydraulic motor is fixedly mounted above the motor mounting base. The upper bearing seat is fixedly connected to the bottom of the motor mounting base. The spiral feeding roller is inclined, and its upper and lower ends are rotatably connected to the upper and lower bearing seats, respectively, via rotating shafts fixed at both ends of the spiral feeding roller. The output shaft of the hydraulic motor is connected to the rotating shaft at the upper end of the spiral feeding roller, and the conical head is connected to the rotating shaft at the lower end of the spiral feeding roller.

[0006] Preferably, the conveying mechanism further includes a correction component located at the tail end of the conveying mechanism. The correction component includes a limiting bracket, a limiting rod, a correction plate, and a compression spring. The limiting bracket is fixedly located on the side of the housing. One end of the limiting rod is fixedly connected to the correction plate, and the other end is movably connected to a limiting hole on the limiting bracket. The compression spring is sleeved on the limiting rod, and both ends are fixedly connected to the correction plate and the limiting bracket, respectively.

[0007] Preferably, baffles are fixedly provided on both sides of the housing.

[0008] Preferably, the conveyor belt assembly has a herringbone pattern on its belt.

[0009] Preferably, the connecting bracket includes a support rod, an upper connecting member, and a lower connecting member. The upper and lower ends of the support rod are respectively fixedly connected to the upper connecting member and the lower connecting member. The upper connecting member is fixedly connected to the motor mounting base, and the lower connecting member is fixedly connected to the lower bearing seat.

[0010] Preferably, the spiral feed roller includes an upper cover, a cylinder, a spiral protrusion, and a lower cover. The upper cover is fixedly connected to the top of the cylinder, the cylinder has a conical structure, the spiral protrusion is fixedly disposed on the outer wall of the cylinder, the lower cover is fixedly connected to the bottom of the cylinder, and the upper cover and the lower cover are respectively fixedly connected to a rotating shaft.

[0011] Preferably, the rotating shaft of the lower plug is provided with an external thread, and the conical head is provided with an internal thread. The rotating shaft of the lower plug is threadedly connected to the conical head through the external thread and the internal thread.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses the spiral feeding roller of the front picking mechanism to reduce the drop of black sesame seeds in the opened pods and capsules through low-damage picking, and at the same time reduces the damage to the black sesame bundles. By installing the spiral feeding roller of the picking mechanism at an angle, the lower part first contacts the black sesame bundles, and the spiral protrusions gradually clamp and pick up the black sesame bundles and tilt them toward the rear conveying mechanism. The contact area gradually increases, improving the coordination with the conveying mechanism. This can realize the orderly picking and feeding of black sesame bundles that have been cut and dried and placed vertically.

[0013] (2) The conveying mechanism of this utility model is equipped with baffles on both sides to prevent the black sesame bundles from rolling off during the conveying process. The belt has herringbone pattern protrusions with intervals to increase friction and prevent the black sesame bundles from sliding down. The correction component at the tail corrects and limits the skewed black sesame bundles. The adjustment is made by the compression spring to ensure that the black sesame bundles are fed into the subsequent device in an orderly manner. Attached Figure Description
