Problems solved by technology

At present, there has been a squeeze-type threshing and separation device, but the inventors have found that the existing squeeze-type threshing device has threshing gaps, the form of threshing elements, and the grid size parameters of the concave plate sieve are not suitable for millet grains when the whole plant is fed. In the case of small diameter, the grains cannot be separated from the concave plate sieve, and are discharged together with the stalks, leaves and other sundries, resulting in a certain loss rate of the grains. Moreover, when the whole crops are fed by the traditional squeezing device, the crops have a high degree of looseness. , the rubbing effect is poor, and the impact on the grain is greater when rubbing, so that the grain has a certain damage rate

Embodiment 1

[0030] This embodiment discloses a squeezing and rubbing type threshing and separating device, such as Figure 1-Figure 2 As shown, it includes a drum 1, the drum can be rotated, a top cover 2 is arranged above the drum, the top cover is fixedly arranged, and can be fixed on a corresponding frame body, and a grid member 3 is provided below the drum, and the grid member is fixedly arranged , which can be fixed on the corresponding frame body, the top cover and the grid member are arc-shaped structures, and after the top cover and the grid member are combined, they can wrap the peripheral space of the drum.

[0031] In another embodiment, both ends of the top cover are provided with fixing plates, and the top cover is fixedly connected to the grid member through the fixing plates.

[0032] The two ends of the drum are the feeding end and the discharging end, respectively. The feeding end of the drum is connected with a feeding part 4. The feeding part adopts a truncated cone-sha...

Embodiment 2

[0052] This embodiment discloses a harvester, which is installed with the squeezing type threshing and separating device described in Embodiment 1, and the drum is connected to a drive mechanism installed on the harvester frame through a first shaft head or a second shaft head , the driving mechanism can be a diesel engine, the diesel engine is connected with the first axle head or the second axle head through a transmission mechanism, and the transmission mechanism can be a chain transmission mechanism or a belt transmission mechanism.

[0053] The top cover and the grid member are both fixed on the frame of the harvester. In order to facilitate the collection of grains, a collection box is arranged below the grid member, and the collection box is fixed on the frame of the harvester.

Abstract

The invention relates to a squeeze-type threshing separation device and a harvester, which include a rotatable drum, a fixed grille is arranged under the drum, a plurality of grain bars are fixed on the first half of the drum, and a There are several groups of nail teeth distributed along the spiral line, and there is a fixed top cover on the top of the drum. The screw pitch of the flow plate becomes larger gradually, and the threshing and separating device of the present invention has a high removal rate and a low grain damage rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a squeezing and rubbing type threshing and separating device and a harvester. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] Grain threshing and separation is one of the key links in combined harvesting. When small-grain crops such as millet are harvested, the moisture content of the straw is high, and the grains on the ears are more. It is necessary to ensure the effective separation of the ears and the stalks and reduce the loss of grains. At the same time, the straw should not be damaged as much as possible to improve the separation effect and reduce the difficulty of cleaning. At present, there are squeeze-rubbing threshing and separation devices, but the inventors found that the existing squeezing-rubbing threshing device has threshing gaps, t...
