Description

A device for collecting and transporting tobacco leaves

technical field

The utility model belongs to the technical field of tobacco leaf picking equipment, in particular to a tobacco leaf picking and transportation device suitable for tobacco fields in mountainous and hilly areas.

Background technique

Affected by crop characteristics, the growth cycle of tobacco in the field is relatively long, and the labor volume, labor time and labor intensity of field operations are much higher than those of other crops. Among them, mature harvesting and baking of tobacco leaves is a relatively labor-intensive link in tobacco agricultural production. The survey results show that the amount of labor employed in this link accounts for about 40% of the labor employed in all production links. At the same time, the mature growth period of tobacco leaves is in the high temperature season of each year, that is, from the end of July to the beginning of September. Due to the influence of climate characteristics, the rainfall in some production areas is concentrated during this period, resulting in high temperature and high humidity during the mature harvesting period, which is relatively difficult for field operations. Great difficulty, especially in mountainous and hilly tobacco areas, where the tobacco fields are relatively scattered and fragmented, affected by the topography and landform, the terrain is uneven, and the field operation conditions lead to higher labor intensity.

The law of tobacco leaf maturation is as follows: tobacco leaves gradually mature from the bottom to the top, that is, the physical properties of layered yellowing. According to the principle of picking when ripe and harvesting when ripe, the number of leaves per plant and batch is 3-4. It takes about 5-6 batches to finish picking and roasting all the tobacco plants. The maturity period of tobacco leaves is relatively concentrated, and tobacco leaves need to be picked and roasted in time after maturity, otherwise it will easily cause over-ripe loss of yield and quality.

Therefore, replacing manual tobacco leaf harvesting with machinery can not only improve operating efficiency, but also reduce labor intensity and labor costs, and increase the economic benefits of growers.

There have been reports both at home and abroad on how to mechanically replace human harvesting.

Research status abroad:

The tobacco harvester technology in the United States, Italy and other foreign countries has developed rapidly, and the self-propelled tobacco harvester is a machine with relatively advanced technology in tobacco harvesting. Among them, the 6360 type self-propelled tobacco harvester produced by the American MarCo company, the 2TTH type harvester produced by the Italian DeCloet company, and the RA341 tobacco leaf harvester produced by the Italian SPAPPERI company are representative. Most of the self-propelled tobacco harvesters are high-power harvesting machines, which are suitable for tobacco fields with large contiguous areas. For small plots, semi-automatic and manual harvesting machines are more adaptable. Such as the semi-automatic tobacco leaf harvester developed and produced by Italy DeCloe, and the RA1TO tobacco harvester produced by SPAPPERTI Company.

Research state in China:

Tobacco harvesters in my country can be divided into self-propelled tobacco leaf harvesters and semi-automatic manual auxiliary harvesters. The tobacco leaf harvester produced by Beijing Debang Dawei Technology Co., Ltd. in cooperation with the Italian company DeCloet is a relatively advanced self-propelled tobacco harvester in China. "A self-propelled tobacco harvester" designed and invented by Liu Guoshun and Liu Jun of Henan Agricultural University. The 4AZ-41 automatic tobacco leaf harvesting machine developed and produced by Kunming is a fully automatic and self-propelled tobacco leaf harvesting equipment, which can realize time-sharing and partial harvesting of tobacco leaves. Beijing Debang Dawei Tobacco Leaf Picking Machine (TYCY-20) is a self-propelled special tobacco machine for tobacco leaf picking, which can manually distinguish and break tobacco, mechanically walk in the field, lift and store without trace, and mechanically unload tobacco. It has three modes of smoke unloading and transshipment: overall unloading of loose leaves, neat subcontracting and transshipment, and neat overall unloading. Xuchang Tongxing Tobacco Leaf Harvester is a self-propelled multifunctional power machine, which can realize the plant protection harvesting operation of the whole process of tobacco, and can test various operating functions by hanging different types of machines.

To sum up, the current harvesting machinery is divided into two types: automatic tobacco leaf harvester and semi-automatic harvester. The semi-automatic harvesting adopts the combination of manual identification and picking and mechanical transportation. In order to meet the functional requirements, the harvesting machinery is large in size. Harvesting machinery has high requirements for field operations, and harvesting machinery is mainly used for trial use in plain tobacco areas. Due to the limitation of current production and agronomy, the damage rate of tobacco plants and harvested leaves is high, and the scope of promotion of tobacco leaf harvesting in plain tobacco areas has not yet been promoted and applied on a large scale.

Tobacco fields in mountainous and hilly areas are affected by the area of the land, topography, and traffic road conditions. The currently developed harvesting machinery is not applicable from entering the field to field operations. Small, light, flexible and adaptable harvesting agricultural machinery and implements are still blank at present.

Tobacco is an economic crop for leaves, and the harvesting process is too extensive, which will cause damage to the leaves and cause irreversible quality decline. Therefore current agriculture is still based on the mode of manually picking leaves one by one, and then collecting and transporting them out of the field.

Through the above analysis, the problems and defects in the prior art are:

Existing tobacco harvesting equipment is mainly used for trial use in plain tobacco areas, and is not suitable for use in mountainous areas and hilly tobacco fields. The tobacco leaves in mountainous areas and hilly tobacco fields are still mainly in the form of manual labor.

1. Fully automatic harvesting machine: The automatic harvesting machine integrates multiple functions such as tobacco leaf picking, collection, conveying and sorting, and transportation. In the process of large-scale intensive production, it is more suitable in plain areas with large plots and suitable mechanical plowing road conditions. However, the current fully automatic harvesting machines are not very good at grasping the maturity of tobacco leaves. The leaf damage rate and The mechanical damage is serious, resulting in a decline in the quality of tobacco leaf curing. Therefore, it is difficult to promote this kind of machinery in production.

2. Semi-automatic harvesting machine: The current semi-automatic harvesting machine uses the operator to ride on the mechanical platform to manually pick the leaves and collect and organize them by the principle of mechanical transportation, which reduces the labor input for manual field transportation of tobacco leaves. However, this kind of mechanical model is relatively large, and the space requirements for field operations are more suitable for large plots. The conditions for entering the field are good, and the fields are more convenient to turn and turn around the plains. At the same time, the requirements for the working space of the tobacco field are relatively high, and it is easy to cause mechanical damage to the unpicked leaves of the tobacco plants during the harvesting process, resulting in reduced production and quality. If the space conditions of the harvesting machinery are met and the row spacing is increased, the number of tobacco plants per mu will decrease, resulting in a decline in yield. Therefore, the current promotion and application area of semi-automatic harvesting machinery is also small.

3. At present, through the screening and configuration of agricultural machinery, it is found that there is no applicable harvesting machinery in mountainous and hilly tobacco fields. Under the current agronomic production conditions, small and micro harvesting machinery (tools) that partially replace manual labor are more in line with actual production needs .

4. In the current production, the method of manually picking leaves is mostly used. After the harvesters enter the field, according to the condition of the mature leaves of the tobacco plants, the leaves are picked from the tobacco plants line by line, plant by plant, and single piece, and then the leaves are picked. After being concentrated into bales, the method of manually carrying out the plots is time-consuming, labor-intensive and labor-intensive in the harvesting process.

5. Tobacco leaves are grown in alternate phyllotaxy, with large leaves and high water content. Improper handling during picking can easily cause damage to the leaves. First of all, the machine picking must ensure that the leaves are not damaged during the picking process, and secondly, on the basis of replacing manual work, the work efficiency should be improved. Therefore, a small volume, light transportation, suitable for small plots of mountains and hills, portable tobacco leaf picking equipment supporting leaf collection, outbound device, is a top priority to meet the current production needs and reduce labor input and labor intensity.
