Vertical threshing and rotary tillage combined harvester

Abstract

The invention provides a vertical threshing and rotary tillage combined harvester which comprises a stalk cutter, a stalk scrabbling wheel, a threshing vertical shaft, a threshing cylinder, a grain receiver, a straw outlet, a girder frame, a gear case and an engine. The grain receiver, an impurity discharge fan and a straw discharge fan are sequentially arranged at the lower portion of the threshing vertical shaft from bottom to top, the middle of the threshing vertical shaft penetrates through the threshing cylinder, the straw outlet is formed in the top end of the threshing vertical shaft, the stalk cutter and the stalk scrabbling wheel are arranged at the front end of the threshing cylinder, the engine and the gear case are arranged on the girder frame, a rotary cultivator is connected in the gear case, and a walking caterpillar track is arranged at the lower end of the girder frame. The whole vertical threshing and rotary tillage combined harvester is provided with a power transmission route, has a function of simultaneously achieving rice-wheat harvesting and field soil rotary tillage, is compact in structural arrangement, small in size, moderate in gravity center and stable and reliable to operate and is also suitable for operation in southern districts.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to an agricultural vertical threshing and rotary tillage combine harvester. Background technique [0002] In many industrially developed countries abroad, the grain harvesting is done with a combine harvester. In our country, despite the rapid development of harvesting machinery in recent years, due to the influence of many factors such as economy and population, the ownership of combine harvesters is still relatively low. [0003] Traditional horizontal threshing can only achieve 180-degree threshing, and additional threshing cylinders and vibrating screens are installed, which cannot shed the grains well and cause more damage to the grains. [0004] The current agricultural harvester crawler self-propelled rotary tiller is different from the rotary tiller on the market. The currently used rotary tiller has four wheels on the ground and has a strong pressure on the ground. Ta...

In my country, despite the rapid development of harvesting machinery in recent years, due to the influence of many factors such as economy and population, the number of combine harvesters is still relatively low.

[0003] The traditional horizontal threshing can only achieve 180-degree threshing, and the additional threshing cylinder and vibrating screen can not shed the grain well and damage the grain more

[0004] The current agricultural harvester crawler self-propelled rotary tiller is different from the rotary tiller on the market. The currently used rotary tiller has four wheels on the ground and has a strong pressure on the ground. Take the 650 type drag rotary tiller as an example, its pressure is 65 About 1,000 Pa, it is easy to cause damage to the field, and the floating mud in the field will become deeper and deeper.
