[0002] Mustard (scientific name: Brassica juncea (L.) Czern. et Coss.) is a member of the cruciferous family. Mustard is a specialty vegetable of China with a long history, a wide variety of species, and extensive cultivation. It is mainly distributed in the Yangtze River Basin and the southwest region. China is one of the original origin centers of mustard. Mustard is divided into four categories of roots, stems, leaves, and stalks, with 16 variants and many variant types. Among them, the stems and leaves of leaf mustard are the main edible parts. The shape of its rhizomes is relatively sturdy, and there are tumorous stems with large differences in size and shape, and the leaves are also relatively large. When mustard matures, the leaves will stick to the ground. At present, the harvest of mustard is generally carried out by manpower, including cutting roots, removing leaves, and transportation, which is extremely labor-intensive.

[0021] The traveling chassis 2 comprises a chassis 21 arranged parallel to the ground and a wheel set 22 mounted on the chassis 21. A whole machine driving device is arranged on the chassis 21 for driving the whole machine to move.

[0022] The flexible leaf-gathering device 3 is installed at the front end of the frame 1. The flexible leaf-gathering device 3 includes a mounting frame 31 arranged parallel to the ground, two groups of pulley groups 32 fixed on the mounting frame 31 and arranged at intervals, two groups of flexible leaf-gathering units 33 arranged on the belt 321 of the pulley group 32, and a belt drive motor 34 driving the two groups of pulley groups 32 to operate. The width of the flexible leaf-gathering unit 33 is greater than the width of the belt 321. The two groups of flexible leaf-gathering units 33 are driven by the two groups of pulley groups 32 to gather the mustard leaves by using the opposite sides of the two groups of flexible leaf-gathering units 32. The width of the flexible leaf-gathering unit 33 is greater than the width of the belt 321. When the whole machine moves forward, the opposite sides of the flexible leaf-gathering unit 33 contact the mustard stems and leaves. The flexible leaf-gathering unit 33 gathers the mustard stems and leaves by using the rotation of the two groups of pulley groups 32 and the power of the whole machine moving forward.

[0023] Specifically, in one embodiment, the mounting frame 31 is a square frame structure, including horizontal bars and vertical bars arranged in parallel, and is hinged to the frame 1. Preferably, the rear end of the mounting frame 31 is hinged to the two side frames of the conveying device 5, and the front end of the mounting frame 31 is connected to the top of the frame of the conveying device 5 through the reinforcing arm 311. The front end of the mounting frame 31 is connected to the top of the frame of the conveying device 5 through the reinforcing arm 311, so that the structural stability of the mounting frame 31 is better, and it is not easy to deflect and tilt during operation, and the structural complexity is not increased.

[0024] The two pulley groups 32 are symmetrically arranged, each pulley group 32 includes a pair of pulleys and a belt 321 looped on the pulleys, the pair of pulleys includes a front wheel 322 and a rear wheel 323, and the front wheel 322 and the rear wheel 323 are passed through the crossbar of the mounting frame 31. The belt drive motor 34 is fixed on the outside of the vertical rod to prevent interference with the flexible leaf unit 33. The belt drive motor 34 is fixed on the outside of the vertical rod to simplify the structure.

[0025] The flexible leaf-gathering unit 33 includes a plurality of leaf-gathering blades 331. Specifically, the plurality of leaf-gathering blades 331 are overlapped and arranged on the belt 321. Preferably, the plurality of leaf-gathering blades 331 are arranged at equal intervals on the belt 321. The plurality of leaf-gathering blades 331 are arranged close to the ground at one end away from the belt 321, so that the mustard leaves close to the ground can be better gathered during operation.

[0026] Preferably, in one embodiment, the leaf-gathering blade 331 is formed by curling a flexible belt to form an upper blade 3311 and a lower blade 3312, and a hollow structure is formed between the upper blade 3311 and the lower blade 3312. Preferably, the upper blade 3311 and the lower blade 3312 have the same shape, and the width of the front and rear ends of the upper blade 3311 and the lower blade 3312 is smaller than the width in the middle, and the edges of the upper blade 3311 and the lower blade 3312 are arc-shaped. The upper blade 3311 and the lower blade 3312 adopt this shape, which is more conducive to first entering the root of the mustard from the top with a small width, and then clamping the mustard through the middle with a larger width. When the raised mustard leaves are gathered, the side of the middle with a larger width contacts and compresses the stems and leaves, completing the leaf-gathering operation of the mustard. Of course, the leaf-gathering blade 331 can also be other shapes, such as a rectangle. The material of the leaf-gathering blade 331 is PVC material, which has the characteristics of being waterproof and moisture-proof, wear-resistant, light, and having good insulation and flame-retardant properties. The leaf-gathering blades 331 are made of the above-mentioned material, have certain flexibility and elasticity, and have resilience through curling to form a hollow structure. Under the operation of the belt 321 and the compression of the mustard stems and leaves, the overlapping leaf-gathering blades 331 use the resilience to gather the mustard stems and leaves.

[0027] The present application utilizes a flexible leaf gathering device 3 to gather the mustard leaves, which is beneficial to the subsequent cutting operation, and at the same time cooperates with the cutting device 4 to harvest the valuable stem and leaf parts of the mustard after cutting.

Preferably, the width of the conveyor belt 52 is similar to the width of the mounting frame 31, and the conveyor belt 52 is connected to the mounting frame 31 through the bracket 51, so that the structure is simpler and more stable.

[0030] The storage box 6 is fixed to the rear end of the conveying device 5 and is fixed to the chassis 21. The cut mustard greens are automatically dropped into the storage box 6 after being conveyed to the top by the conveyor belt 52.

[0031] The working principle of the horizontal leaf-gathering mustard harvester of the present application is as follows: when the harvester is working, the mustard plants are first rowed, and the frame 1 drives the whole machine to move forward through the walking chassis 2. At the same time, the flexible leaf-gathering device 3 rotates with the rotation of the two groups of pulley groups 32, and the belt 321 rotates. The mustard leaves close to the ground are lifted up from bottom to top by the flexible leaf-gathering unit 33 on the belt 321. When the lifted mustard leaves are gathered, the leaf-gathering blades 331 of the flexible leaf-gathering unit 33 contact and compress the stems and leaves, completing the leaf-gathering operation of the mustard, and exposing the root and stem parts to be cut by the cutting device 4 arranged between the belts 321. After cutting, the mustard is inverted on the conveyor belt 52 of the conveying device 5, and is transported to the top by the conveyor belt 52. The yellow and rotten leaves are picked out by manual assistance behind the conveyor belt 52, and finally fall freely to the storage box 6 under the action of gravity, thereby completing the mustard harvesting operation.
