1、 脱粒机使用注意事项汇总脱粒机一般由喂入装置、脱粒装置、分离装置、清选装置、输送装置和机架等组成。脱粒时,谷物由人工铺放到喂入台上,经喂入台送入脱粒装置,由滚筒脱粒。脱粒后的长茎秆从出草口被抛出。谷粒及杂余混合物从凹板的空隙落下,轻杂余被风扇产生的风力吹出机外,粮食落入出粮口后流出1。设计有2级滚筒的机型,谷物经第1级滚筒脱粒后进入第2级滚筒,进行第2次脱粒,提高了脱粒净度,与普通机相比具有较高的脱净度。具有风扇和清选筛2种清选装置的机型,在风力清选的基础上,部分不能被风力吹出的轻杂物经清选筛清选后送出机外,加强了清选效果,清选出的粮食较为干净,清洁率明显优于普通机型。设计有逐稿器的脱粒机脱粒

2、时,脱粒后的长茎秆经过逐稿器时被逐稿器不断抖动,使夹带在其中的籽粒被分离出来落入清选装置中,减少了籽粒的夹带损失。Sheller generally is composed of feeding device, threshing device, separation device, cleaning device, transmission device and rack etc. Threshing, grains by artificial laid on the feeding stage, the feed into the threshing device, by roller t

3、hreshing. Threshing mouth is thrown after long stem from the grass. Grains and the mixed residual mixture from the concave plate, the gap more than light noise produced by fan wind blowing outside, and that food after falling into a grain outlet flow out 1. Level 2 cylinder model is designed, after

4、level 1 roller threshing grain into the drum of level 2, second for threshing, improves threshing clarity, compared with PuTongJi has high clarity. With fan and cleaning sieve cleaning device models, on the basis of the wind power cleaning, parts can not be the wind blow out impurities after cleanin

5、g sieve cleaning out the closed, strengthened the cleaning effect, qing choose food is more clean, QingJieLv is superior to ordinary models. Design of walkers thresher threshing, threshing long stalks after a draft apparatus were each manuscript is constantly shaking, make the entrainment in the gra

6、in is separated out falls to the cleaning device, reduce the entrainment loss of grain. sty-480型的脱粒机的清选工作则由扬场机来完成,脱粒时,由螺旋式推运器将籽粒和轻杂余运入扬场机,由扬场机以较大惯性向空中斜线抛出,籽粒由于质量大被抛出较远,而其他轻余被抛出较近,清选工作立即完成。Sty - 480 type of threshing cleaning work is done by grain thrower, threshing, the push screw conveyor will be m

7、ore than impurity substances in grain and transported into the grain thrower, with larger inertia slash thrown into the air by grain thrower, the grain due to the large mass thrown far away, and are more than other light thrown, cleaning work to be done immediately. 2脱粒机的安全使用技术2 thresher the safe us

8、e of technology 2.1使用前准备2.1 before use 一是安全检查。拧紧松动的螺母,如皮带轮、机架、紧固螺丝、滚筒间隙调整螺母,滚筒纹杆或钉齿紧固螺母等,以防发生机械或人身伤亡事故。检查滚筒、皮带轮、轴承座等部件有无裂缝、断开或其他损坏情况。二是试运转。首先在各运转部门加注润滑油,装好传动皮带,先用人力带动脱粒机转动,查看有无卡滞、碰撞和其他异常现象,若有应及时排除。然后接上动力,进行空运转试验,正常后即可试脱,若无问题,就可转入正式使用2。三是脱粒机作业场地要选平坦开阔的地方,并注意自然风向,出草和麦糠出口尽量与自然风向一致,以利于草和麦糠的顺利推出。当用于手扶拖拉机

9、作动力配套时,应注意排气管的方向,不要面向出草和麦糠出口,也不要朝下安装以免引起火灾。四是操作人员衣着要紧凑,女同志要将发辫包起,防止衣服或头发卷入滚筒或传动皮带造成意外人身伤亡事故。严禁儿童在机器周围玩耍。Is a security check. Tighten the loose nut, such as pulley, frame, gap adjusting nut fastening screws, rollers, roller rod or nail tooth fastening nut, etc., to prevent mechanical or personal casu

10、alty accidents. Check whether there is any crack on roller, pulley, bearing and other parts, disconnect, or other damage. Second, the test run. In lubricating oil, various operation departments listed first installed drive belt, with human turns thresher, first check whether binding, collision and o

11、ther anomalies, if any should be ruled out in time. Then plug in power, empty running test, normal test after take off, if no problem, can be used into formal 2. Three is threshing operation area should choose flat open areas, and pay attention to natural wind, the grass and husks to export as far a

12、s possible consistent with the natural wind, to facilitate the smooth introduction of grass and the chaff. When used in walking tractor as power matching, we should pay attention to the direction of the exhaust pipe, dont be geared to the needs of the grass and the chaff exports, also do not want to

13、 install so as not to cause fire. Four is operator dress to compact, female comrade will wrap braids to prevent clothes or hair in rollers or personal casualty accident caused by drive belt. It is forbidden to children play around in the machine. 2.2脱粒机的调整2.2 the adjustment of the thresher 脱粒机的调整,尽可

14、能做到脱粒与清选干净、破碎率低、损失小。调整时,要兼顾滚筒转速、滚筒间隙和风量大小三者关系以取得最佳效果。一是滚筒转速的调整。不同作物对脱粒机滚筒转速的要求有所不同,如脱小麦的滚筒转速一般要求在1 000 r/min左右。当用电动机作动力时,转速一般是固定的,喷灌设备在这种情况下,只要选用合适的电动机皮带轮,使滚筒转速达到额定值即可匹配。熔铝炉有些脱粒机在出厂时厂家配备有电机皮带轮,但也有不配备的,自制时可依照下列公式计算皮带轮直径:电机皮带轮的直径电机转速=滚筒皮带轮的直径滚筒转速。当用手扶拖拉机作动力时,由于转速的调节范围较大,因此与脱粒机配套比较灵活。这时脱粒机的转速通过手扶拖拉机的油门

15、控制。根据经验,脱粒机的滚筒转速高,脱净率高,破碎率高;转速低,脱净率低,破碎率低3。二是滚筒间隙的调整。滚筒间隙指滚筒和与凹版之间的间隙,一般在15 cm。间隙大,脱净率低,破碎率低;间隙小,脱净率高,破碎率高。滚筒间隙根据作物的品种和干湿情况进行调整,易脱作物和作物含水率低时适当调大,不易脱粒作物和作物含水率高时可适当调小。三是风量调整。风量大时,清选出的粮食较为干净,但易造成籽粒夹带损失。风量小时,清选效果稍差,但籽粒夹带损失减少。调整时要兼顾上述两方面,尽量做到损失少、清洗干净。Threshing machine adjustment, as far as possible do th

16、reshing and cleaning clean, low broken rate, low loss. Adjustment, should take the roller gap, roller speed and air volume size triadic relation in order to obtain the best results. One is adjusting the rotational speed of roller. Different crops is different to the requirement of threshing cylinder

17、 rotation speed, such as wheat drum rotation speed of the general requirements in 1 000 r/min or so. When motor as power, speed is usually fixed, in this case, as long as you choose the right motor pulley, the roller speed rating can match. Some thresher factory factory are equipped with a motor pul

18、ley, but there are not equipped with self-control when according to the following formula to calculate the pulley diameter: the diameter of the motor pulley * motor speed = the diameter of the roller pulley * roller rotation speed. When using walking tractor as power, because of its high speed adjus

19、ting range, therefore with thresher is more agile. The thresher speed throttle control through the walking tractor. Based on experience, high threshing cylinder rotation speed, take off the net rate is high, the broken rate is high; Speed is low, take off the net rate is low, low broken rate 3. 2 it

20、 is roller gap adjustment. Cylinder clearance refers to the gap between roller and intaglio, generally in 1 5 cm. Gap is big, to take off the net rate is low, the broken rate is low; Small gap, to take off the net rate is high, the broken rate is high. Roller clearance according to the crop varietie

21、s and dry wet circumstance to adjust, easy to take off the crop and the crop moisture content low when appropriate, when not easy threshing crops and crop moisture content is high, can appropriate adjust little. Third, air volume adjustment. Qing choose food for large air volume is relatively clean, but easy to cause the grain entrainment loss. Air volume hours, cleaning effect is a bit poor, but the grain entrainment loss reduced. Adjustment to take into account the above two aspects, try to be less loss, clean.
