    摘要:

    基于矩形循環(huán)圖法，設(shè)計(jì)了一種籽瓜挖瓤機(jī)。上瓜機(jī)構(gòu)采用改進(jìn)的擺動(dòng)凸輪機(jī)構(gòu)，插瓜架轉(zhuǎn)位機(jī)構(gòu)選擇兩圓銷四槽輪機(jī)構(gòu)，挖瓤刀升降機(jī)構(gòu)選取平底式直動(dòng)從動(dòng)件盤形凸輪機(jī)構(gòu)與改進(jìn)的杠桿傳動(dòng)。以試驗(yàn)機(jī)為基礎(chǔ)進(jìn)行籽瓜挖瓤正交試驗(yàn)，確定了適合籽瓜挖瓤的工藝參數(shù)：挖刀類型為半圓形挖刀、挖刀轉(zhuǎn)速為240r/min、挖刀安裝角度為15°。重復(fù)試驗(yàn)表明：該挖瓤機(jī)挖凈率在98%以上，籽粒潔凈率在98%以上，損失率在2%以內(nèi)，破碎率小于1%。

    Abstract:

    Based on rectangle circulating chart method, a seed melon pulp-excavated machine was designed. Improved swinging cam was used for feeding melon mechanism, a 2-round pin and 4-grooved wheel mechanism were chosen to realize precise indexing motion of a plug melon saddle, and flat-bottom tappet disc cam mechanism with improved rod gear mechanism was used for lifting tool saddle. The orthogonal experiment was done and the optimum parameters of digging was discovered as follows: the type of digging tool is hemicycle, the speed of digging tool is 240r/min and the installation angle of digging tool is 15°. Replicated tests showed the cleaning rate is more than 98%, grain seedless rate is more than 98%, loss rate is less than 2% and broken rate is less than 1%, respectively.
