Description

TECHNICAL FIELD

[0001] The utility model relates to a vegetable harvesting machine technical field especially relates to a high whole plant rate's vegetable harvesting machine for automatic vegetable production line. BACKGROUND

[0002] In the process of agricultural modernization, agricultural production, especially vegetable production, has become a development trend of industrialization, automation and intelligentization. The production of stem and leaf vegetables is seriously affected by the progress of intelligentization of vegetable production due to the large amount of labor and the high difficulty of field mechanized harvesting. The cultivation tank and substrate planting method and modern industrial landmark equipment are used to complete the planting, harvesting and packaging of vegetables on the production line.

[0003] According to the patent with the announcement number CN218042752U, the stem and leaf vegetable intelligent production workshop is arranged and set in the intelligent workshop. The automatic harvesting and packaging flow line composed of the vegetable harvesting flow line and the vegetable packaging flow line is organically combined with the cultivation tank-substrate recycling flow line and the seedling automatic seeding flow line to form a complete intelligent production flow line, so that the whole chain intelligent and automatic production of vegetables can be realized. Since consumers have the habit of consuming whole green leaf vegetables, they do not accept vegetables with damage and leaf dispersion. The patent "automatic vegetable harvesting and packaging flow line" (patent number ZL202123323767.2) published on May 24, 2022. The principle is that the planting tank is placed on the conveying line and moves forward with the conveying belt. The harvesting is completed when the cutter installed above the planting tank passes. Since some vegetable varieties such as Chinese cabbage and green vegetables have a considerable proportion of root and stem connection parts below the upper opening of the planting tank, this part of the vegetables will appear scattered after passing through the cutter. Although the method solves the problems of high labor cost and low efficiency of traditional manual harvesting, the whole plant rate is only 40-60%, which obviously cannot meet the demand of consumers for vegetable product specifications. It seriously affects the sales price of vegetables. Therefore, a high whole plant rate vegetable harvesting machine is proposed to solve the above problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Referring to Figures 1-5 A high whole plant rate of vegetable harvesting machine for the automatic vegetable production line, comprising:

[0028] Planting groove limiting mechanism 1 is used for limiting the position of vegetable planting groove and limiting the planting groove from being lifted simultaneously when the vegetable is lifted;

[0029] The vegetable clamping and lifting mechanism is a flexible conveyor belt used to hold and lift the vegetables so that their roots are exposed before the cutting mechanism's blades. The lower part of the flexible conveyor belt is installed close to the planting trough and tilts forward and upward.

[0030] The cutting mechanism is located on one side of the planting trough limiting mechanism 1. When the vegetables with exposed roots are picked up by the flexible conveyor belt and passed by the cutter, they are cut and transferred to the post-harvest processing workbench by the flexible conveyor belt.

[0031] Frame 2 is used to install planting trough limiting mechanism 1, vegetable clamping and lifting mechanism and cutting mechanism.

[0032] When this device is in use, after the vegetables are placed in the planting trough limiting mechanism 1, the vegetables can be clamped and lifted by the vegetable clamping and lifting mechanism to expose their roots and stems. During the lifting process, the cutting mechanism cuts the vegetables according to their roots. Compared with the existing technology, this device can harvest vegetables with a high whole plant rate, effectively meeting consumers' demand for vegetable product specifications.

[0033] In this embodiment, the vegetable clamping and lifting mechanism includes two sets of belt conveyor devices 3, with the belts of the two sets of belt conveyor devices 3 moving in opposite directions and arranged side by side in parallel. There is a height difference between the inlet and outlet of the belt conveyor device 3, which facilitates the exposure of the thinner root diameter of the vegetable. The belt conveyor device 3 is driven by a motor to drive the active wheel and the driven wheel, which drive the flexible clamping belt to circulate. The motor and the driven wheel are both mounted on the frame 2, and the driven wheel is rotatably connected to the frame 2. At the same time, during actual installation, the gap between the two sets of flexible conveyor belts can be adjusted according to the size of the vegetables to accommodate vegetables of different sizes.

[0034] In this embodiment, the cutting mechanism includes a tool position adjustment device 4, a tool driving device disposed at the driving end of the tool position adjustment device 4, and a tool 10 disposed at the driving end of the tool driving device.

[0035] In this embodiment, the tool position adjustment device includes at least three linear drive modules (e.g., electric slides) connected in sequence to realize the spatial point position adjustment and locking of the tool 10 in the three coordinate (XYZ axis direction).

[0036] In this embodiment, the tool driving device includes a rotary motor 5, a cam 6 disposed on the driving end of the rotary motor 5, a connecting rod 7 rotatably mounted on one side of the surface of the cam 6, and a fixed seat 8 rotatably mounted on the other end of the connecting rod 7. The tool 10 is fixedly mounted on the fixed seat 8, and a tool limiting seat 9 (i.e., a sheath) is provided on the frame 2. The tool 10 moves horizontally through the tool limiting seat 9. The rotary motor 5 drives the cam 6, and the rotational motion is converted into linear motion to drive the tool 10 to complete the cutting.

[0037] In the embodiment, the planting groove limiting mechanism 1 is fixed on the rack 2 through a sliding groove, and is used for adjusting the position of the planting groove limiting mechanism 1 and the cutter 10, so as to avoid that the planting groove collides with the cutting edge of the cutter 10.

[0038] The planting groove limiting mechanism 1 mainly limits the top position of the planting groove, and with the operation of the vegetable clamping lifting mechanism, the vegetables in the planting groove can be lifted to expose the root, and the whole plant can be conveniently cut by the cutter.

[0039] In the embodiment, the entrance of the belt conveyor 3 is designed to be wide outside and narrow inside, so as to facilitate the introduction and clamping of the vegetables.

[0040] In the embodiment, the end of the belt conveyor 3 is further provided with a cutting and conveying device 11 (a belt conveyor can also be used) and a circular turntable 12 (an electric turntable is used) connected in sequence, so as to conveniently convey the vegetables after cutting.

[0041] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and the changed field operation machine is also covered in the protection scope of the present application.
