Description

Technical Field

[0001] The utility model relates to the technical field of crop harvesting devices, in particular to a small Chinese cabbage harvester suitable for farmers' operations. Background Art

[0002] Chinese cabbage, also known as headed cabbage or Chinese cabbage, was called "Song" in ancient times. It is a horticultural crop of the genus Brassica and has a history of 5,000 years. It has the characteristics of cold tolerance, high yield, and short growth cycle.

[0003] At present, the harvesting of Chinese cabbage is still mainly manual, with a large workload, so that the Chinese cabbage planted by many farmers cannot be effectively harvested. Some of the small Chinese cabbage harvesters recorded in the prior art have complex structures, large floor areas, and high costs, and are not suitable for most farmers to use. Based on this, there is an urgent need for a harvesting device that can effectively harvest Chinese cabbage and is relatively small to solve the above problems. Summary of the Utility Model

[0004] The utility model aims to at least improve one of the technical problems existing in the prior art. For this purpose, the utility model provides a small Chinese cabbage harvester suitable for farmers' operations.

[0005] The small Chinese cabbage harvester suitable for farmers' operations according to the first aspect embodiment of the utility model includes:

[0006] A main body bracket, the main body bracket includes a bottom beam and a top beam;

[0007] A pulling-out mechanism, the pulling-out mechanism is fixedly installed at the front end of the main body bracket, and specifically includes a pulling-out shovel and its fixing parts. The pulling-out shovel is fixedly installed on the main body bracket through the fixing parts, which is used to shovel the soil near the root of the Chinese cabbage to achieve the effect of loosening the soil. Secondly, after the pulling-out shovel shovels away the soil, it can prevent the pressing blade of the cutter from rubbing against the land, thus hindering the normal movement of the cutter. In addition, the pulling-out shovel can also pull out the Chinese cabbage;

[0008] A clamping and conveying mechanism, the clamping and conveying mechanism is fixedly installed on the main body bracket. The clamping and conveying mechanism has an inlet end and an outlet end. The clamping and conveying mechanism includes two first motors, two driving rollers, several driven rollers, and two clamping conveyor belts. The two ends of the driving rollers and the driven rollers are respectively connected to the bottom beam and the top beam through fixed bearings. The first motors are fixedly installed on the top beam, and the output shafts of the first motors are coaxially connected to the driving rollers. A clamping conveyor belt is tensioned between the driving rollers and the driven rollers. The first motors drive the driving rollers to drive the clamping conveyor belts to move, so as to fix and drive the Chinese cabbage to move horizontally;

[0009] Root cutting mechanism, the root cutting mechanism is fixedly installed at the bottom of the inlet end of the clamping and conveying mechanism. The root cutting mechanism includes a second motor and a cutting knife. The second motor is fixedly installed on the bottom beam, and the output shaft of the second motor is fixedly connected to the cutting knife;

[0010] Conveying and lifting mechanism, the conveying and lifting mechanism is fixedly installed on the bottom beam. The conveying and lifting mechanism is connected to the outlet end of the clamping and conveying mechanism and is used to lift the transported Chinese cabbage to the top of the conveying and lifting mechanism;

[0011] Collection box, the collection box is fixedly installed on the conveying and lifting mechanism. After the Chinese cabbage is lifted to the top of the conveying and lifting mechanism by the conveying and lifting mechanism, it falls into the collection box to complete the collection work of the Chinese cabbage.

[0012] The small Chinese cabbage harvester suitable for farmers' operations according to the embodiment of the present invention can pull out the Chinese cabbage through the pulling mechanism and then clamp it by the clamping and conveying mechanism, so that the Chinese cabbage on the soil surface can be cut in an upright form. After the roots of the Chinese cabbage are cut, the Chinese cabbage can be conveyed into the collection box by the clamping and conveying mechanism and the conveying and lifting mechanism, thereby realizing the cutting and collection of the Chinese cabbage. The whole collection process does not require manual participation, greatly improving the harvesting efficiency of the Chinese cabbage. Moreover, the device of the present invention has a simple structure and low cost, is suitable for most farmers to use, and has good application prospects.

[0013] In a possible implementation manner of the first aspect, the clamping and conveying mechanism is symmetrically arranged about the midline of the main body bracket. Among them, the clamping conveyor belt between the root cutting mechanism and the conveying and lifting mechanism is arranged parallel to the midline, which is convenient for ensuring that the Chinese cabbage can be orderly conveyed to the conveying and lifting mechanism.

[0014] In a possible implementation manner of the first aspect, the driven roller includes a plurality of adjustable tension wheels, which is convenient for adjusting the gap and tightness between the clamping conveyor belts to adapt to the transportation and clamping of Chinese cabbages of different sizes.

[0015] In a possible implementation manner of the first aspect, the second motor and the cutting knife are symmetrically arranged about the midline of the main body bracket. Among them, the cutting knife includes two overlapping disc cutting knives, and the second motor is a DC reduction motor, which is convenient for driving the cutting knife to cut the roots of the Chinese cabbage.

[0016] In a possible implementation of the first aspect, the conveying and lifting mechanism includes a third motor, two rotating shafts, a belt conveyor, and side guards. The third motor is fixedly installed below the top beam of the main body bracket. The two rotating shafts are respectively arranged below the frames of the bottom beam and the top beam. A belt conveyor is provided between the two rotating shafts. Specifically, a plurality of stoppers may be provided on the surface of the belt conveyor or an anti-slip layer with a large coefficient of friction may be installed. The third motor is coaxially connected to the rotating shaft close to the top beam. Side guards are provided on the main body bracket outside the belt conveyor to prevent the Chinese cabbages from slipping out during conveying and lifting.

[0017] In a possible implementation of the first aspect, the main body bracket is made of spliced aluminum alloy profiles, which has low cost and light weight and is suitable for farmers to use.

[0018] In a possible implementation of the first aspect, the surface of the clamping conveyor belt in direct contact with the Chinese cabbages is a rough frosted layer to prevent the Chinese cabbages from slipping during transportation.

[0019] In a possible implementation of the first aspect, universal wheels are provided at the bottom of the main body bracket, which is convenient for movement and adapts to the harvesting work in different vegetable fields.
