Problems solved by technology

However, such a traditional seed threshing method is labor-intensive and time-consuming, and the efficiency is low
Although there are many seed threshing equipments on the market, such as millet thresher, etc., for the weed seeds used in scientific research, the existing equipment is relatively large, which is not conducive to the threshing of a small amount of weed seeds, and the design of millet thresher etc. It is designed according to the size of millet, and the size difference between weed seeds and millet is large, and the size of different weed seeds is also different, so the existing thresher is not suitable for threshing weed seeds

Embodiment 1

[0051] like figure 1 As shown, a kind of seed threshing equipment provided by Embodiment 1 of the present invention includes a cylinder 1, and also includes a shearing device 2, a peeling device 3, and a separation device 5 sequentially arranged in the cylinder 1; wherein, the shearing device 2 It includes a first driving mechanism and a shearing mechanism, the first driving mechanism is fixed on the cylinder body 1, and the shearing mechanism is in transmission connection with the first driving mechanism; the peeling device 3 includes a second driving mechanism and a kneading mechanism, and the second driving mechanism is fixed on On the barrel 1, the kneading mechanism is connected to the second drive mechanism in transmission; the separation device 5 includes a blower mechanism and a lead-out mechanism, the blower mechanism is fixed on the side wall of the barrel 1, and the lead-out mechanism is arranged on the other side of the barrel 1. on the side wall. Further, the sto...

Embodiment 2

[0066] The essential difference between the second embodiment and the first embodiment is that: an adjustment bracket and a collection mechanism are also provided.

[0067] like figure 2 As shown, the seed threshing equipment provided by Embodiment 2 of the present invention has a main structure similar to that of Embodiment 1. For the specific structure, please refer to the description of Embodiment 1. The purpose here is to explain the difference between the two.

[0068] The above-mentioned fixed washboard 31 is fixed on the cylinder body 1 through an adjustment bracket; the adjustment bracket includes a telescopic rod 10, a fixed sleeve 11 and a locking member 9, the fixed sleeve 11 is fixed on the outer wall of the cylinder body 1, and one end of the telescopic rod 10 extends into the fixed sleeve In 11, the other end of the telescopic rod 10 is connected to a fixed washboard, and the telescopic rod 10 and the fixed sleeve 11 are locked by a locking member 9. In the spe...

Embodiment 3

[0072] The substantial difference between the third embodiment and the first embodiment is that a guide tube is also provided.

[0073] like image 3 As shown, in the present embodiment, a guide tube 8 is arranged between the above-mentioned shearing device 2 and the peeling device 3, and the guide tube 8 is fixed in the cylinder body by a bracket, and the inlet of the guide tube 8 is connected to the outlet of the shearing device 2, The outlet of guide pipe 8 is connected with the feeding port of peeling device 3 .

[0074] In the specific operation, through the setting of the above-mentioned conduit, the effective guidance of the seeds can be realized, and the seeds output from the shearing device 2 can be smoothly guided to the feeding port position of the peeling device 3, which can effectively prevent the unpeeled seeds from peeling the peeling device. 3 One side leaks, which can effectively improve the peeling rate of seeds.

Abstract

The invention discloses a seed threshing apparatus comprising a cylinder, and further comprising a shearing device, a peeling device and a separating device arranged in the cylinder in sequence. The shearing device comprising a first driving mechanism and a shearing mechanism. The first driving mechanism is fixed to the cylinder, and the shearing mechanism is in drive connection with the first driving mechanism. The peeling device comprising a second driving mechanism and a rubbing mechanism, the second driving mechanism is fixed to the cylinder, and the rubbing mechanism is in drive connection with the second driving mechanism. The separating device comprises a blowing mechanism and a leading-out mechanism, the blowing mechanism is fixed to the side wall of one side of the cylinder, and the leading-out mechanism is arranged on the side wall of the other side of the cylinder. The seed threshing apparatus can be applied to the technical field of agricultural equipment, can effectively make up the shortcomings in the prior art, can realize convenient threshing operation of weed seeds, and can effectively improve practical operation efficiency.

Description

technical field [0001] The present application relates to but not limited to the technical field of agricultural equipment, especially a seed threshing equipment. Background technique [0002] The collection and treatment of weed seeds is the prerequisite for the study of weed biology, ecology, seed germination and dormancy, and weed resistance to herbicides. However, weed seeds collected in the primary stage are often wrapped by tepals or lemmas, for example, the seeds of Chenopodiaceae and Amaranthaceae are often wrapped in the persistent tepals, and the seeds of grass weeds are often covered by glumes or lemmas. If the tepals or lemma skins are not removed, it will often affect the later seed germination. Therefore, before weed seed germination experiments or weed seedling cultivation, weed seeds need to be threshed. [0003] At present, the seeds are separated from the tepals or lemma skins by repeated rubbing by hand or with the aid of sandpaper, so as to achieve the e...
