Rice harvesting and spreading machine

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a rice harvesting and spreading machine. The rice harvesting and spreading machine comprises cutterdiscs, a machine frame, a transmission device and a gear shaping device; the machine frame comprises a box body and a traction connecting piece; the transmission device is rotationally connected to the box body; a left connecting rod and a right connecting rod which are symmetric with each other are arranged on a conveying belt; an end of the left connecting rod is connected with an end of the right connecting rod through an elastic strip; the connecting positions of at two sides of the elastic strip are respectively located below the end of the left connecting rod and the end of the right connecting rod; the gear shaping device comprises a material pushing plate, a sliding block and a pressing rod; one end of the pushing plate is hinged to one side of the box body; a sliding groove is formed in the pushing plate; and the material pushing plate is obliquely placed; the sliding block is slidably arranged in the sliding groove of the material pushing plate through a spring; the pressingrod is slidably arranged on the sliding block; and the pressing rod can extend out of the surface of the pushing plate. The invention provides the rice harvesting and spreading machine. Through the arrangement of the gear shaping device in the box body, harvested rice can be discharged at uniform intervals, so that the harvested rice can be conveniently laid and aired, and harvesting after airingis facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a rice harvesting paver. Background technique [0002] In 1988, my country began to try planting ratooned rice, but manual harvesting has been used during this period, which is labor-intensive and time-consuming. In addition to the shortage of rural labor force, it is an inevitable trend for the development of my country's grain industry and agricultural machinery to use machinery to harvest ratooned rice. At present, although there are many types of rice harvesters and they are widely used, they all use 40-60cm wide walking wheels or crawler wheels. The field walking is heavy and the height of the stubble is low. It is only used for dry soil or sun-dried paddy fields. Not suitable for rice harvesting. [0003] There are also some rice harvesting equipment in the prior art, such as a Chinese patent with the application number 2014101170654 disclosing a high cleara...
