Problems solved by technology
[0002] The grain harvested by the harvester contains more impurities, which bring more problems to the later grain processing, and the impurities also add a lot of extra load to the harvester, and will also occupy a large amount of grain storage containers of the harvester The space in the middle reduces the amount of grain that the grain storage container can actually hold

Embodiment Construction
[0018] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0019] The advantage of the screw impurity removal device for the harvester of the present invention is: it has a screw feed pipe, which can make the grain particles flowing through have a larger downward partial velocity, so that they can be discharged from the discharge port faster , Reduce the grain particles discharged together with impurities, thereby increasing the grain harvest rate.
[0020] Such as figure 1 , figure 2 As shown, a spiral impurity removal device for a harvester includes a conical box 1, an impurity discharge pipe 2 and a mixing feed pipe 3. Feed port 11, the lower end of the impurity discharge pipe 2 is arranged in the conical box 1, and the spiral impurity removal dev...

The invention discloses a spiral impurity removal device for a harvester. The spiral impurity removal device comprises a conical box, an impurity discharge pipe and a mixed feeding pipe. The conical box is arranged in a big-end-up mode, a discharging outlet is formed in the lower end of the conical box, the lower end of the impurity discharge pipe is arranged inside the conical box, the spiral impurity removal device for the harvester further comprises a blastpipe and a spiral feeding pipe, the spiral feeding pipe is wound around the impurity discharge pipe, and the upper end of the spiral feeding pipe is connected with the mixed feeding pipe and the blastpipe. The spiral impurity removal device for the harvester has the advantages that the spiral feeding pipe is arranged, and grain granules flowing through the pipe have the large downward component velocity, so that the granules can be more rapidly discharged from the discharging outlet, grain granules discharged along with impuritiesare reduced, and therefore the harvesting rate is increased.
Description
technical field [0001] The invention relates to the field of agricultural machinery, more precisely a spiral impurity removal device for a harvester. Background technique [0002] The grain harvested by the harvester contains more impurities, which bring more problems to the later grain processing, and the impurities also add a lot of extra load to the harvester, and will also occupy a large amount of grain storage containers of the harvester The space in the container reduces the amount of grain that the grain storage container can actually hold. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a spiral feeding pipe, which can make the grain particles flowing through have a relatively large downward component velocity, so that it can be discharged from the material faster. It is a spiral removal device for harvesters that reduces the grain particles discharged together with impuriti...
