Light and small elevating quick assembling and disassembling rice and wheat harvester

Abstract

The invention discloses a light and small elevating quick assembling and disassembling rice and wheat harvester comprising a harvesting assembly, a chassis assembly, a power assembly and a straw cutting cutter row assembly, wherein an ear outlet of a shear and an ear inlet of a threshing barrel are directly connected to form an integral harvesting assembly; the straw cutting cutter row assembly is positioned on the front end of the lower underframe of the chassis assembly; the rear part of the harvesting assembly is provided with an affiliated embedding spile assembly; the upper end of the chassis assembly is provided with an affiliated embedding socket assembly; the rear lower part of the chassis assembly rack is provided with a spile slot and a tensioner; the top of the chassis assembly is provided with a cord drawing device; the lower part of the power assembly is provided with a spile; and the movable cutter bar of the straw cutting cutter row assembly is provided with a left grass feeding huge-tooth assembly, a right grass feeding huge-tooth assembly and a grass separator. The harvester can be free from the limitation of hills, montanic field narrow roads or single bridge. During harvesting, the harvester is free from limitation of muddy feet depth and abnormity, small plots and bent and narrow fields. The working efficiency of the harvester is higher than any rice and wheat harvester which can be carrier by two people for times.

Description

technical field [0001] The invention relates to a light rice and wheat harvester suitable for hills and mountainous areas. Background technique [0002] Known full-feed rice and wheat harvester before the present invention is made. There are following defects for hilly, mountainous area rice, wheat harvesting: one, transshipment is inconvenient: the mountainous area paddy field is all in the mountains, and in a long period of time, it is difficult to realize machine plowing road to the field. The two couldn't lift it, and rice and wheat harvesters with a wheelbase wider than 50 centimeters couldn't go in and harvest. Second, the traditional structure of the harvester blade has a high failure rate, and the edge of the fixed blade is not wear-resistant and not sharp: Reason ① The cutting surface of the blade guard is to play the role of cutting the fixed blade, but the overall blade guard includes the cutting surface They are all steel castings. After heat treatment and quen...

AI Technical Summary

Problems solved by technology

There are the following defects in the harvesting of rice and wheat in hills and mountainous areas: First, the transportation is inconvenient: the rice fields in mountainous areas are all in the mountains, and for a long time, it is difficult to realize the mechanical farming road to the field

The cutting working surface is in the shape of 2×6cm straight strips, with a space of more than 5.5 cm between each other, and the guiding plane is extremely narrow. When the moving blade moves back and forth in a straight line on the cutting working surface of the blade guard, the moving blade can easily enter the blade guard Cutting the space of the working surface will cause the cutting surface to be stuck and damage other transmission parts with serious consequences

Third: The whole machine is bulky, there is a relatively large drop distance from the ear outlet of the cutting platform to the ear inlet of the threshing barrel. The existing equipment is equipped with ear feeding troughs, lifting ear feeding belts and transmission devices, which can reduce weight. Lightweight non-metallic materials are not used instead, and the field mattress is compacted when the wet field is harvested, which brings difficulties to the second plowing, especially the muddy paddy field

Its four: also have the known small-sized model all-feeding rice, wheat harvester, also exist because of small volume, can't place winnowing, the defects such as the high impurity rate except existence above defect

Therefore, rice and wheat harvesters with no special structure have not been applied and promoted by farmers in hilly and mountainous areas.
