Description
Technical Field
The invention relates to an improved component structure of an agricultural machinery peanut combine harvester, in particular to an improved structure of a picking and harvesting component, an auger component and a conveying groove of the peanut harvester
Background
Peanuts are used as important oil crops and high-quality protein resources, and the planting area and yield of China are in the front of the world. According to the statistics of Chinese statistics annual-differentiation, the peanut planting area of China is 6923.6 mu, the yield is 1644 mu ton, and the second place and the first place of the world are respectively occupied in 2015. In developed countries, only a few countries such as the united states are planted on a large scale, and the planting area 626 and khm in 2016 account for 2.46% of the planting area of peanuts in the world. In China, the peanut planting distribution is wide, and the peanut planting distribution is mainly concentrated in regions such as Henan, shandong, guangdong, hebei, liaoning, anhui, jiangsu and the like, wherein the variety of the planted peanut is up to 300, and the planting mode is various.
Although China has a wide planting area and a large output, most areas are mainly produced manually and semi-mechanically, especially in the harvesting operation link, the labor consumption is about 1/3 of the whole production process, and the operation cost is about 50% of the total production cost; meanwhile, with the development of town, the loss of rural young labor is serious, so that the rural labor cost is increased, and the production and development of the peanut industry are severely restricted.
Mechanization is used as a main way for improving the agricultural production efficiency and reducing the labor cost, and provides powerful guarantee for the agricultural production development. Along with the gradual maturity of the mechanization of main production links of rice, wheat, corn and other main crops, the development of peanut harvesting machinery is greatly supported by the state and various levels of governments and has more comprehensive development. According to the differences of operation modes, planting varieties and the like in different areas, the mechanized harvesting of peanuts mainly comprises two operation modes, namely combined harvesting operation and two-section harvesting operation. The combined harvesting is that one harvesting machine can finish a series of harvesting procedures from digging, conveying, picking fruits and cleaning to collecting fruits, and two-stage harvesting is that the digging machine is used for digging in the field and then airing for a period of time, and then the peanut seedlings are picked up by the picking combined harvester and conveyed to the subsequent picking, cleaning, collecting fruits and other parts, so that the picking and harvesting operation is finished.
When the combined harvester is picked up for operation, along with the forward movement of the harvester, peanut seedlings are picked up by picking up spring teeth under the interaction of the seedling pressing device and the pickup device, and move along the surface of the grass sliding plate under the continuous pushing of the picking up spring teeth to enter the conveying auger; under the rotary motion of the auger, peanut seedlings are conveyed to the interface part of the harvesting table frame in a concentrated mode, enter the subsequent working parts and finish picking up and harvesting operations.
At present, similar products exist at home and abroad, but because foreign peanut varieties and China are different, the foreign peanut varieties are mostly grown in creeping form, each peanut seedling is interwoven with each other, similar to carpets, blocking and winding phenomena are not easy to occur during harvesting, and the Chinese peanut varieties are mostly grown in upright form, so that the foreign peanut harvester is not suitable for the Chinese peanut varieties and is high in price. At present, similar products in domestic markets are not mature enough, in order to prevent winding blockage, similar elliptical track type pick-up devices are adopted for domestic products, a seedling sliding plate is directly connected with an auger concave plate, seedling hanging blockage is easy to occur at the position, and the manufacturing process is complex and high in cost.
The height of the picking up spring tooth mounting frame, the gap between the screw feeder and the screw feeder concave plate, the relative included angle between the picking up spring tooth and the seedling sliding plate are directly related to the operation level and quality of the peanut combine harvester picking up device, and the technologies of the disclosed patent 'a peanut picking up and harvesting screw feeder', a peanut picking up and anti-jamming delivery device ', a peanut picking up and combine harvesting mechanism' and the like are improved on parts of an improved structure of the peanut combine harvester, and the performance of the peanut combine harvester is improved and improved, but the improved structure of the peanut combine harvester is large in national use quantity, wide in operation area, and great in use value and significance due to any improvement and improvement.
The outstanding problem at present is that the direction of rotation of picking up spring tooth and screw feeder will form the opposite direction rotation by chain, sprocket direct connection, is unsuitable for the machines actual action requirement, in order to reach the equidirectional backward rotation requirement, must dispose the steering gear, leads to the defect that the structure is complicated, heavy, trouble is many.
Secondly, the conveying groove and the screw feeder are connected, and because the conveying groove and the screw feeder are huge in size, the conveying groove, the screw feeder and the screw feeder are often required to be mutually detached and connected in the links of transportation, operation, maintenance and the like, the screw feeder is connected by bolts and screws in the past, the disassembly and assembly are very difficult, and the connecting position is concentrated in stress and easy to damage.
Furthermore, the transmission shaft of the transmission groove is easy to wind peanut seedlings, so that the transmission groove transmission chain is easy to jump teeth to cause distortion of the transmission scraping plate, the transmission is unsmooth, the working quality is affected, and when the machine is seriously paralyzed, the machine is stopped for cleaning and clearing at intervals, and the operation speed, quality and efficiency are affected.
The above problems and disadvantages are very much in need of improvement and resolution.
