According to test data conducted by M. E. Dodds and F. B. Dyck when cutting wheat, oats and barley at a table angle of 15°, the value of ξ, the ratio of forward speed to canvas speed, is chosen in the range 0.79 to 1.31 so as to get optimal windrows.When windrowing wheat, oats and barley, the superior limit of ξ is 1.31 while the inferior limit 0.61.The formulas ( 3 ) to ( 7 ) have been found which indicating the relationships between ξ and d, Bo,K, S1, S2,etc., and can be used in windrower calculation.Under...

According to test data conducted by M. E. Dodds and F. B. Dyck when cutting wheat, oats and barley at a table angle of 15°, the value of ξ, the ratio of forward speed to canvas speed, is chosen in the range 0.79 to 1.31 so as to get optimal windrows.When windrowing wheat, oats and barley, the superior limit of ξ is 1.31 while the inferior limit 0.61.The formulas ( 3 ) to ( 7 ) have been found which indicating the relationships between ξ and d, Bo,K, S1, S2,etc., and can be used in windrower calculation.Under test conditions conducted by M. E. Dodds and F. B. Dyck, the scope of allowed values S2 have been counted in this paper and the equation ( 7 ) has been discussed. When the yield Wo increases, value ξ tends to decrease correlatively (or to increase value d) and vice versa, so that counted values aren't beyond the scope of allowed one. If ξ, d are constant, changes in Wo will cause S2 easily to go beyond the scope of allowed values S2.ξ of an windrower is not a fixed value and it may be selected within certain limits in theory as well as in practice.

根据Dodds和Dyck先生的试验资料,在割晒小麦、燕麦和大麦以及β=15°时,ξ值在1.31~0.79间选取,可获得最佳的条放。 割晒三种麦类作物,ξ上限值为1.31而下限值为0.61。 本文推导公式(3)至(7),它表示出ξ值与d,B_0,K,S_1,S_2等关系,可用于割晒机运算之中。 本文求出在Dodds和Dyck先生试验条件下,S_2值的允许范围并讨论了等式(7)。为了使计算值S_2不超过其允许值的范围,在W_0增加时,相应降低ξ值(或增大d值),反之亦然。如果ξ,d值一定,W_0变化易引起S_2超过允许值S_2的范围。 无论从理论还是从实践中,割晒机ξ值选择不应是一个数值而应当是区间值。

With the aid of a handlebar at the outer hive, the strip was revolved rectangularly, making the teeth force into the spaces between the neighboring side-bars to fasten the frames. This device, without opening the hive, handles quickly, conveniently and efficiently, with little vibration. As soon as...

The working efficiency will bo raised 15-fold.

把巢脾快速固定器弹簧钢齿的圆钢装在蜂箱的前后壁上,让圆钢方形一端伸出左右箱壁。用插手在箱外把圆钢向内、向下旋转90度,使圆钢上的卡框齿挤入相邻两巢脾侧梁间的蜂路内,把巢脾挤住卡牢。这种固定巢脾的方法,不必开箱、操作方便、振动小、速度快、效率高。把圆钢旋回90度,固定随之拆除,工效约能提高15倍。

Profits of certain farm machinery group for variable service areas are also differeat. The variable machinery cost per unit area can be conceived as constant, while the fixed machinery cost per unit area will be drop down as the service area grows up. The. relationship between the machinery cost and service area can be shown as hyperbolic curve on coordinate diagram. If the essential farm op-eration can't be performed in the due time period, timeliness loss will occur, the yield will drop. This paper derived analytically the relationship between the net production value per unit area and the service area. This relationship can also be shown in the same diagram as parabolic curve. This curve usually intersects with the said hyperbola at two points,the abscissas of these points indicate the lower and upper limit of the service areas of given machinery group, the perpendicular distances between two curves represent the net income per unit area. This net income can also be drawn as a curve Y on the same diagram. The poin ta twhich Y = max shows the optimum service area. Calculate and draw all the Y-curves for every possible machinery group, from these cur-ves, we can find a series values of Y for a given service area. Within these Y values, there will be a max. value, which is on the curve corresponding to reasonable machinery group for given area A. This paper derived all these me-ntioned calculating methods analytically. These methods are applied to Jia County, Hebei, on eight machinery groups for nine different service areas. The results of calculations on the machinery equipments are pretty close to the present real situations.

机群的服务规模不同,经济效益也不同。单位面积上机械作业的可变费用基本上为一常数,而分摊的固定费用则随服务面积的增大而减小。经过推导,单位面积上的机械作业费与服务面积间的关系图形为一双曲线。另一方面,关键作业项目若不能在适时期内完成,亩产量将受到损失,推导出的单位面积净产值与服务面积间的关系图形为一抛物线。在同一坐标图上,一般可得出两曲线的两个交点,交点对应的面积即为该机群服务范围的上下限,两曲线间的垂直距离表示单位面积的纯收益,也可在同一坐标图上用曲线Y表示,最大垂直距离的面积为最佳服务面积,此时Y=max。将全部可供选择的机群的Y曲线绘出后,对于给定服务面积A,可查出各机群对应的Y值,其中最大值所对应的机群,即为面积为A时的合理机群结构。本文用解析方法对上述思路作出推导,并用河北省晋县的实例对八种机群及不同规模进行了计算,得出不同规模时的配备方案,与晋县实际情况相当吻合。
