蜂王浆三针夹取式拣虫机的设计与试验

蜂王浆拣虫是挖浆前必须完成的工序。由于蜜蜂幼虫个体较小、数目庞大,因此人工拣虫过程劳动强度非常大;然而中国养蜂人员老龄化日益严重,且目前蜂王浆拣虫机械化尚未成熟。该文针对中国养蜂现状提出一种以三针夹取的方式将王台中蜜蜂幼虫夹出的方法。以三针夹取的拣虫方式构建蜂王浆拣虫机整机方案。三根针在王台孔内壁同时做向心运动或分离运动,将蜜蜂幼虫夹住或松开。对传动机构中球面槽轮和凸轮的参数进行计算。通过有限元分析得出动力输入端脚踏板受力情况。计算得出球面槽轮圆柱销弧长7.5π,槽深20.68 mm;得出凸轮的理论廓线;有限元分析结果得出动力输入方式可靠。该机器在保留蜂王浆幼虫完整的前提下,一次性将整条王台(64孔)中蜜蜂幼虫全部拣出,可实现连续作业,拣虫效率为10条/min时为人工的10倍,克服了蜂场手工作业时间长和劳动强度大问题。对扩大中国蜂业养蜂规模有着极大的促进作用。

Efficacy observation on cervical spondylosis of nerve root type treated by the warm needling at Jiájǐ(夹脊EX-B 2) and tapping with plum-blossom needle

Objective To observe the clinical effect on cervical spondylosis of nerve root type treated by warm needling therapy at Jiáj （夹脊 EX-B 2） and plum-blossom needle therapy. Methods According to the random number table, 150 cases of cervical spondylosis of nerve root type were randomized into an acupuncture-moxibustion group （75 cases） and a control group （75 cases）. In the acupuncture-moxibustion group, the warm needling at EX-B 2 and tapping with plum-blossom needle were applied. EX-B 2 on the affected segments were selected and stimulated with warm needling technique for 20– 30 min. Afterward, the plum-blossom needle was used to tap the skin around the acupoints, for 3 min on each site. The treatment was given once every day. Seven treatments made one session. The interval between two sessions was 1 day. In the control group, the medication was used in combination with traction therapy. The intravenous drip with 5% glucose 250 mL and compound salvia miltiorrhiza injection 40 mL was used, once a day. In traction treatment, the patient was in a sitting position, neck anteflexion at 15°–30°, traction force at 10%–20% of the body mass, for 20–30 min in each time. The treatment was given once every day. The appointed person evaluated therapeutic effects after the three sessions of treatment in the two groups. Results The clinical curative rate was 49.3% （37/75） and the total effective rate was 94.7% （71/75） in the acupuncture-moxibustion group and those were 24.0% （18/75） and 81.3% （61/75） respectively in the control group. The total effective rate and clinical curative rate in the acupuncture-moxibustion group were superior to the control group （both P0.05）. In the comparison of the duration of treatment and effect in the cured patients between the two groups, the curative rate in the 1st session of treatment in the acupuncture-moxibustion group was higher than that in the control group （P0.05）. In the comparison of the 6-month follow-up visit in the cured patients between the two groups, the effect in the acupuncture-moxibustion group was much more stable （P0.05）. Conclusion The warm needling therapy at EX-B 2 and tapping therapy with plum-blossom needle achieve the significant effect on cervical spondylosis of nerve root type.

Objective： To compare the effect differences of electroacupuncture（EA） at Jiajǐ（夹脊 EX-B2） and conventional acupoints for lumbar intervertebral disc herniation（LIDH） and the factors influenced the effect during the way of data mining.Methods： A total of 160 patients of LIDH were randomly assigned into the EX-B2 group and the conventional acupoints group, 80 cases in each one. The patients in the EX-B2 group received EA at the symmetrical 2 acupoints of the bilateral EX-B2 on the lesion part. The patients in the conventional acupoints group received EA at the tender point of the lesion part, Zhibian（ 秩边BL54）, Huantiao（环跳 GB30）,weǐzhōng（委中BL40）, Chéngshān（承山BL57） and Fúyáng（跗阳BL59） on the affected side. The retain time of the needles is both 45 min. The treatment of the two groups is 3 times a week and for a connective 20 times. The modified Assessment Criteria for Low Lumbar Pain of Japanese Orthopedic Association（JOA）,Visual Analogue Scale（VAS） were evaluated before and after the treatment and at the 6-month follow up.Results：（1） Effective outcomes. JOA score： The JOA score of the patients in the EX-B2 group after treatment was（20.89 士 3.43）, and was（19.35 ±4.02） on the follow-up. Compared with the JOA score（12.35 ±4.42） in the same group before the treatment, there were statistical significant higher（both P0.05）. The JOA score in the EX-B2 group after treatment and on the follow-up were both higher than that of the conventional acupoints group at the same time point（both P0.05）. VAS score： The VAS score of the patients in the EX-B2 group on the 24 h after the first treatment was（4.09 ± 1.81）, and was（2.11 ± 1.30） after the treatment. Compared with the VAS score（4.09 ± 1.81） in the same group before the treatment, there were statistical significant lower（both P0.05）. The VAS score in the EX-B2 group on the 24 h after the first treatment and after treatment showed no statistical differences than that of the conventional acupoints group at the same time point（both P0.05）.（2）Related results from data mining： The middle-aged people and disease duration less than six months, their effect of the immediate treatment was the best. According to JOA score, EA at EX-B2 was better than EA conventional acupoints,either in the process of treatment effect, or in pertinence of the treatment, which were superior to EA conventional acupoints therapy; The best curative effect time of EA at EX-B2 was the first treatment after24 h, and the best curative effect of the conventional acupoints was after the first treatment. The age and disease duration also affected curative effect.Conclusion： The effect of EA at EX-B2 was superior to the conventional acupoints in treating LIDH.
