Description

Technical Field

[0001] The utility model relates to the technology of harvesting leafy vegetables in an orderly row-by-row manner, in particular to a leafy vegetable harvester and a leafy vegetable row-by-row gathering and lifting device thereof. Background Art

[0002] Leafy vegetables are rich in nutrients and are common vegetables on the table. At present, the harvesting of leafy vegetables is mainly carried out manually. With the continuous increase of labor costs, it is of great significance to promote mechanized harvesting. The existing harvesting methods usually adopt the overall conveying within the width range of the ridge. Since the stems and leaves of leafy vegetables are brittle, tender and juicy, the requirement of low damage rate cannot be met, and manual sorting is still required later, so the harvesting quality needs to be improved. There is an urgent need in this field for a lifting device that can gather and collect in rows to facilitate the subsequent orderly collection of leafy vegetables and reduce the harvesting damage rate.

[0040] The structural principle and working principle of the present utility model will be specifically described below with reference to the accompanying drawings:

[0041] See Figure 1 , Figure 1 which is a schematic structural diagram of a leafy vegetable harvester according to an embodiment of the present utility model. The leafy vegetable harvester of the present utility model is suitable for row-by-row and orderly harvesting of leafy vegetables that need to be harvested with roots. It includes a chassis 1 and a reaping table 5 installed at the front end of the chassis 1. A row-dividing and gathering lifter 6 is installed at the front end of the reaping table 5. A handrail 2, a battery 7 and a drive 3 are provided at the rear end of the chassis 1. An ordered conveying mechanism 4 is also provided corresponding to the reaping table 5. Since the composition, structure, mutual positional relationship, connection relationship and functions of other parts of the leafy vegetable harvester can all adopt relatively mature existing technologies, they will not be elaborated here. Only the row-dividing and gathering lifter 6 of the present utility model will be described in detail below.

[0042] See Figures 2 - 4 , Figure 2 which is a schematic structural diagram of the row-dividing and gathering lifter 6 according to an embodiment of the present utility model, Figure 3 which is a front view of the right side plate 62 according to an embodiment of the present utility model,Figure 4 The top view of the right side plate 62 of an embodiment of the present utility model. The leafy vegetable row-dividing and gathering lifter 6 of the present utility model is installed at the front end of the harvesting table 5 of a leafy vegetable harvester, and is characterized in that the leafy vegetable row-dividing and gathering lifter 6 includes a left side plate 61 and a right side plate 62 which are symmetrically arranged in a mirror image, and the left side plate 61 and the right side plate 62 jointly enclose a row-dividing and gathering channel 67; the left side plate 61 and the right side plate 62 respectively include a dividing and gathering flat plate 63 and a lifter curved plate 64 which are smoothly connected, and the dividing and gathering flat plate 63 is located at the front end and is parallel to the ground; the lifter curved plate 64 extends backward and upward from the connection with the dividing and gathering flat plate 63, and the divergent growing stems and leaves of the leafy vegetables to be harvested gradually gather along the row-dividing and gathering channel 67 from the front end of the dividing and gathering flat plate 63 to the rear end of the lifter curved plate 64. Among them, the left side plate 61 and the right side plate 62 are preferably 3D printing resin material parts.

[0043] In this embodiment, the front opening of the row-dividing and gathering channel 67 is larger than the rear opening, and the front opening of the row-dividing and gathering channel 67 gradually decreases inward along the horizontal direction of the ridge width, and the rear part of the row-dividing and gathering channel 67 rapidly decreases and tightens inward along the vertical direction. Multiple groups of the leafy vegetable row-dividing and gathering lifters 6 can be arranged in parallel at the front end of the harvesting table 5 as needed. According to the agronomic requirements of leafy vegetable planting and the divergence range of stems and leaves, the distance between adjacent leafy vegetable row-dividing and gathering lifters 6 is preferably 15 cm; the minimum distance between the left side plate 61 and the right side plate 62, that is, the width of the row-dividing and gathering channel 67, is preferably 6 cm.

[0044] Among them, the lifter curved plate 64 is a spatial curved plate with a variable curvature structure, and during the harvesting process, the lifter curved surface is always in contact with the stems and leaves of the leafy vegetables. The lifter curved plate 64 includes a transition section 641 and a gathering section 642. The front end of the transition section 641 is smoothly connected to the rear end of the dividing and gathering flat plate 63, the rear end of the transition section 641 is smoothly connected to the gathering section 642, and the curvature of the transition section 641 is greater than the curvature of the gathering section 642. The dividing and gathering flat plate 63 includes a dividing and gathering front end 631 and a connecting portion 632, and the dividing and gathering front end 631 is a smooth arc tip structure and is close to the ridge surface to avoid damaging the stems and leaves.

[0045] This embodiment may further include a fixing column 65, and the fixing column 65 is arranged on the outer side of the lifter curved plate 64, and a threaded hole 66 may be provided at the center of the fixing column 65 for convenient installation.

[0046] During operation, the dividing and leveling plate 63 travels close to the ground, guiding and gathering leafy vegetables in the vertical direction and the horizontal direction along the ridge width. The front end has a larger opening and is close to the ridge surface. The horizontal opening at the rear end gradually narrows, and both sides quickly narrow in the vertical direction. It can comb and gather the scattered leaf petioles in the same direction and guide them to the position of the cutting edge in the middle of the blade, enabling the single-row leafy vegetables to be gathered and sorted in an orderly manner, facilitating the subsequent conveying after cutting. The lifting and guiding curved plate 64 combs the leaf spread from bottom to top, slowly gathering the stems and leaves that grow divergently in the same direction, facilitating the subsequent orderly conveying, bundling, and collection after cutting. According to the growth characteristics of the leaf petioles of leafy vegetables and combined with the agronomy of strip sowing (usually with a row spacing of 15 cm), the size and installation distance of the lifter are set. Multiple groups of mirror-symmetrical lifters can work together to complete the orderly harvesting of leafy vegetables in rows.

[0047] The row-dividing and gathering lifter of the present utility model can play a good role in row division during the harvesting process of leafy vegetables. As the harvester moves forward, it can comb and gather the leafy vegetables from bottom to top in the same direction. Especially for leafy vegetables with earlier tillering of the root leaves and lush upper leaves, the effect of row-dividing and gathering is more prominent, avoiding damage to the leaves during the harvesting process and greatly improving the appearance quality of the leafy vegetables. After harvesting, the leafy vegetables are in good order, realizing the orderly collection of leafy vegetables.

[0048] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
