Description

Conveying and leaf removing device of green vegetable head harvester

Technical Field

The utility model relates to a leaf device, especially a leaf device are carried to green vegetable head harvester on harvester belongs to agricultural machine technical field.

Background

The famous Brassica napobrassica (L.) Moench is the main raw material for making Fuling hot pickled mustard tuber. The harvesting of the head of the green vegetables always mainly adopts manual harvesting, has high labor intensity and low working efficiency, and seriously influences the yield, the quality and the economic benefit of the preserved szechuan pickle. The reason why the mechanized harvesting of the vegetable heads is difficult to realize is the unique growth characteristics (refer to Xue Yuanpeng, Chenjie, Ye jin, etc.. research on physical and mechanical characteristics of the vegetable heads [ J ]. proceedings of university in southwest (Nature science edition), 2017, 39(2): 147-. The roots and the head of the green vegetables are developed, but the stems and the leaves are fragile and easy to break, so that the harvesting mode of firstly pulling and then cutting the roots is difficult to realize; and the nodular stems have the characteristics of large size difference, specific growth shape and the like, so that the clamping and harvesting difficulty of the nodular stems is high.

In order to solve the above problems, chinese patents of application numbers 201910252863.0, 201610521653.3, and 201810967933.6 respectively propose various technical solutions of a harvester for green vegetable heads. However, researches show that although the vegetable head harvester proposed by 201910252863.0 adopts a V-shaped cutter to cut roots and penetrate into soil, the vegetable head can be damaged in the harvesting process, ridging is not needed, the requirement on soil block flatness is not high, secondary root cutting and defoliation are needed, and particularly, stem and leaf breakage is easily caused by secondary root cutting after soil breaking and secondary root pulling, so that the harvester is blocked. 201810967933.6A mustard tuber harvester is characterized in that a front mustard tuber leaf cutting assembly is used for cutting stem leaves of mustard tuber and then cutting roots of the mustard tuber by a reciprocating cutter, and has the following problems: 1) the overall shape of the nodular stem is approximately spherical or ellipsoidal, so when the vegetable head is harvested by firstly cutting leaves and then cutting off the vegetable stem, the root of the vegetable head is difficult to cut off by a reciprocating cutter which is only close to the front of the lower bearing bottom plate after the upper stem leaves are cut off, and the plant is easy to fall; 2) the bottom of the nodular stem of the vegetable head is close to the soil surface, and part of the nodular stem is even slightly sunk in the soil surface, so that the reciprocating cutter does not have a proper cutting position, namely the cutter is contacted with the middle lower part of the nodular stem when the position is too high, and the nodular stem is seriously damaged; if the position is too low, the cutter is cut into the soil surface, so that the cutting resistance is huge, the cutter is very easy to damage, and meanwhile, the condition of soil accumulation caused by bulldozing is directly caused, so that the harvesting process is interrupted. 201610521653.3A mustard tuber harvester can complete harvesting of mustard tuber by clamping and pulling the device and the front disc root cutter in small areas in hilly and mountainous areas, but for the cabbage head which has less fiber content of stem leaves, more water and is easy to break, the spokes and the clamping belt on the middle bracket easily cause the stem leaves to be rubbed and broken in the conveying process, so that a large amount of stem leaves of the cabbage head are directly pushed to a fixed cutter without power input under the extrusion and gathering effects of the clamping belt, and the cutter is easy to cut off the stem leaves smoothly, thereby causing the jam of the stem leaves.

In particular, the prior art fails to solve the following two problems: 1) the stem leaves and the nodose stems of the green vegetable heads are properly separated and conveyed after cutting, namely the growth characteristics of the green vegetable heads determine that the stem leaves are dense and easy to break, the nodose stems and a large amount of scattered stem leaves are mixed on a conveying belt and difficult to mechanically separate, and the late separation not only influences the harvesting efficiency and the quality, but also easily causes unsmooth conveying and hinders the smooth operation of the harvesting process of the green vegetable heads; 2) reliable clamping and conveying of the vegetable heads, namely, the nodular stem is special in shape and greatly different in size, so that the vegetable heads with different sizes cannot be adapted by adopting a mode of directly clamping and conveying the vegetable heads from two sides of the nodular stem.
