Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a harvesting, crushing and stubble-killing integrated machine. Background Art

[0002] The harvester was invented by Cyrus McCormick. The harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, and collects the grains into the storage bin, and then transports the grains to the transport vehicle through the conveying assembly. It can also be harvested manually, and the straw of crops such as rice and wheat is spread on the field, and then picked up and threshed by grain harvesting machinery. Crop harvesting machinery that harvests grains and straw of cereal crops such as rice and wheat. It includes harvesters, reapers, balers, grain combine harvesters and grain threshers. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools.

[0003] With the increase in crop yields, crop stalks have become increasingly thicker and taller, and the operating efficiency of traditional harvesters has continued to decline. Many farmers use harvesters with high stubble retention. This operating method reduces the amount of straw fed, but greatly increases the amount of rice ears fed. The cleaning capacity of the cleaning fans in traditional harvesters is difficult to cope with, which brings considerable pressure to the transportation, threshing and cleaning of traditional harvesters, and leaves a large amount of straw that is difficult to handle. Most farmers use the method of direct burning, which seriously pollutes the environment.

[0004] A Chinese patent with application number 201510714841.3 discloses a wheat harvester, which includes a machine body and a harvesting blade assembly. A stubble removal assembly is arranged between the machine body and the harvesting blade assembly, and the stubble removal assembly is connected to the machine body transmission component. The invention easily completes stubble removal by installing a stubble removal assembly between the machine body and the harvesting blade assembly. The structure of the stubble removal assembly makes it possible to easily complete stubble removal using a belt drive without increasing power, thereby achieving one-time completion of harvesting and stubble removal, and directly crushing the straw and returning it to the field, solving the worries of farmers in planting. However, the invention still has the problems of transportation difficulties and insufficient threshing when the amount of rice ears fed increases, and the stubble removal assembly used in the invention is not flexible enough. When encountering hard objects, the stubble removal assembly is easily damaged, affecting the operation of the machine. Summary of the invention

[0045] The present invention helps farmers to achieve high stubble operation. This operation mode leaves more than 40 cm of stubble during harvesting, which is much larger than the 8-12 cm stubble of normal harvesting. With the substantial reduction in the amount of feed, the straw-to-grain ratio is greatly reduced, and the threshing load is only 60% of that of normal operation, which greatly reduces the entrainment of grains with straw, and the threshing effect is better and the efficiency is higher. The threshing effect is enhanced, the threshing efficiency is improved, and at the same time, the remaining straw can be crushed and stubble-killed to achieve the return of straw to the field. The stubble left in the field is chopped by a stubble killer, and the fed straw is crushed together by a stem crusher, and then rotary tillage is performed in sequence to return the straw to the field.
