Description

A self-propelled multifunctional harvesting pick-up device

technical field

The utility model relates to a self-propelled multifunctional harvesting and picking device, which belongs to the technical field of agricultural machinery and equipment.

Background technique

The rural areas in the south are located in hilly areas. In recent years, animal husbandry has developed rapidly, and the corresponding forage planting area has also continued to expand. At present, the forage planting is all small and medium-sized pastures, and the fields are of different sizes and heights. It is difficult for large electric lawn mowers to operate in these areas. Most small and medium-sized pastures have limited operating funds, and it is impossible to spend huge sums of money to purchase complete sets of forage harvesting equipment. , The cost of operating a large complete set of electric lawn mowers is relatively high. Manual harvesting with a sickle is inefficient, and the forage is harvested multiple times in a growing period, so there is an urgent need for harvesting machinery suitable for small and medium-sized pastures. At the same time, my country is a big grain-producing country, and the geographical conditions of grain production are different. The drying of grain is the most arduous labor in rural areas. After the grain is dried on the ground, the grain must be swept together, and then imported with a shovel. Bags, which is not only a waste of time, but also very labor-intensive. If there is a rainy day during the drying of grain, the speed of grain harvesting will directly affect the grain harvest of the year. Large-scale grain drying and harvesting machines are mainly used in plain areas, but large-scale machines are not applicable in hilly areas, and rural areas are mainly planted by self-employed households. extremely important for rural areas. Therefore, there is an urgent need for a small and medium-sized harvesting and picking machine in the hilly areas of southern my country.

Regarding lawn mowers, some existing small lawn mowers can no longer meet the needs of lawn area development due to low productivity and high labor intensity; while some large disc rotary forage harvesters are suitable for high-density artificial lawn mowers. Planting and natural grassland harvesting, not suitable for use on small fields and for lawn mowing. Although the development of lawn mowing machinery in China has formed a certain scale, in the southern provinces and cities, most lawn mowers used for greening lawns are hand-held or walk-behind electric or gasoline engine-driven small lawn mowers. The small lawn mower has a single function; the machinery for harvesting grass is not suitable for lawn mowing, and the lawn mower for mowing lawn is not suitable for grass harvesting. Even if it can be harvested, the productivity is quite low and the labor intensity is high. About grain picking machinery At present, there are several grain harvesting machines on the market, but they are all large grain harvesting machines, and some also have trucks for grain harvesting. The scope of application is limited to large drying yards and is not applicable to rural areas. At the same time, there are also some patents for small grain harvesting machines, but due to the relatively large size of the whole machine, incomplete grain harvesting and the need for external power supply, it is not conducive to the use of farmers' families.

Based on the above analysis, it can be seen that the lawn mowers and grain harvesters currently on the market are not perfect, and there is no equipment with cutting and picking functions. Large-scale equipment is more suitable for use in plain areas, but not suitable for use in southern hilly areas; while small-scale equipment, There are problems such as cumbersome operation, complex structure, single function, high precision requirement and high cost. Therefore, it is necessary to design a device that has the functions of harvesting and picking up and is suitable for the use of hills and small areas in southern my country.
