BS EN 13739-1:2011EN 13739-1:2011 (E) 4 Introduction The objective of this Europe
19、an Standard is to specify requirements for fertilizer distributors used according to the instruction handbook, so that: a) unintentional spreading of fertilizers is avoided; b) an even distribution of fertilizer with the desired application rate is achieved. This European Standard does not include a
20、ny direct requirements for the longitudinal distribution. The requirements for evenness of flow rate will partly cover that subject. BS EN 13739-1:2011EN 13739-1:2011 (E) 5 1 Scope This European Standard specifies requirements for the environmental protection for design and construction of mounted,
21、trailed and self-propelled full width solid fertilizer distributors and solid fertilizer broadcasters used in agriculture and horticulture. It also gives the requirements for the minimum content of the instruction handbook. The standard does not apply to machines which are: a) combined grain and fer
22、tilizer drills; or b) equipment for distributing granulated pesticides; or c) solid fertilizer line-distributors (which are dealt with in EN 13740-1:2003 and in EN 13740-2:2003). Personal safety aspects have not been considered in this standard; they are dealt with in EN 14017:2005+A2:2009. If the t
23、erm machine is used it covers both full width distributors and broadcasters, except in the definitions. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the

31、13739-1:2011 (E) 7 3.10 application rate weight of solid fertilizer applied per unit area, in kg/ha 3.11 flow rate amount of solid fertilizer leaving the feeding system(s), in kg/min NOTE The relation between the flow rate and the application rate is given by the following formula: Flow rate (kg/min
32、) = application rate (kg/ha) travelling speed (km/h) working width(m) :600 3.11.1 intended flow rate flow rate desired by the user 3.11.2 obtained flow rate flow rate given by the machine for a certain machine control setting during spreading in simulated conditions as described in EN 13739-2 3.12 s
33、pillage fertilizer which falls uncontrolled from the machine to the ground when the feeding device is closed or disengaged 4 Requirements 4.1 General The machine shall be designed to allow easy handling and adjustments for different types of fertilizers to be used, in order to ensure that the chosen
34、 amount of fertilizer per area is spread evenly and in the area at which it is aimed. The machine shall fulfil at least the requirements given 4.2 up to 4.13. NOTE The manufacturer should also take into consideration that the machine may work in a corrosive environment. 4.2 Hopper filling opening Th
35、e machine shall be designed to minimize the risk that undesirable materials will cause blockages and influence the flow rate or the distribution spreading pattern in a negative way. This can for example be achieved by a grid. 4.3 Cleaning and emptying of residuals Emptying and collecting the fertili
36、zer from the hopper shall be possible without spreading and without unintentional flow to the ground. If tools are necessary to empty the hopper they shall be delivered with the machine and a place shall be provided on the machine for their storage. It shall be possible for a person, standing on the
37、 ground or on the existing access means to clean the machine. 4.4 Contact with obstacles On a full width distributor fitted with a boom with a working width more than 10 m, the outer end of the boom shall be able to move backwards in case of contact with obstacles in the field. If the full width dis
38、tributor is moved forwards at 8 km/h and the obstacle is within 90 % to 100 % of half the boom width measured from the BS EN 13739-1:2011EN 13739-1:2011 (E) 8 middle of the track, the boom or sections of the boom shall be able to give way without being damaged (see Figure 2). The boom sections shall
39、 return automatically to their original position after contact with the obstacle. Key 1 Half boom width Figure 2 Identification of half boom width4.5 Estimation of hopper volume The basic-hopper of the machine (e.g. the hopper without any extension walls), shall be fitted with a scale in litres by w
40、hich the volume of fertilizer in the hopper can be determined. The scale shall cover at least 10 % to 80 % of the basic-hopper volume and have a graduation for at least each 10 % of the nominal volume of the basic-hopper. The accuracy of the graduations shall be within 10 % of the reading. 4.6 Adjus
41、tment of flow rate 4.6.1 Machines with a hopper volume of 600 l or more, shall either be equipped with: a) relevant calibration aids (for example chute, guide, collector) to adjust the flow rate; or b) a system which controls the flow rate automatically (for example load-sensor, mass flow control).
42、4.6.2 If the machine is fitted with a manually controlled system which allows a variation of the flow rate, then this variation range shall be at least 20 % of the intended flow rate, but shall not exceed the limit values defined in 4.13. 4.6.3 It shall be possible to make the adjustment stepless or
43、 in steps of maximum 10 % of the intended flow rate. BS EN 13739-1:2011EN 13739-1:2011 (E) 9 4.7 Flow rate regulation system If the machine is fitted with an automatic system which controls the flow rate, depending on speed, working width, and application rate, the deviation of the obtained flow rat
44、e from the intended flow rate shall fulfil the requirements of Table 1. The adjustment of the feeding system with fertilizer of type a) as defined in 4.2 and 4.3 of EN 13739-2:2011 shall occur within 5 s when adjusting the flow rate from the flow rate 3 by changing parameters, influencing the regula
45、tion system, by 50 %, but shall not exceed the limit values defined in 4.12.1. 4.8 Adjustment of working width It shall be possible to adjust the machine to a different working width (for example to a reduced working width) and for border spreading even when the hopper is filled with fertilizer. 4.9
46、 Feeding device The control(s) (e.g. lever, switches, etc.) of the feed mechanism shall have a clearly marked on and off position related to opened and closed feed mechanism. This marking can be replaced by an indicator visible to the operator at the drivers position, showing whether the feed mechan
47、ism is on or off. 4.10 Spillage With the feeding device closed or disengaged, no spillage shall occur from the filled machine to the ground during transport. 4.11 Evenness of transversal distribution 4.11.1 Field spreading The evenness of the transversal distribution for fertilizer distributors shal
48、l be such that the calculated value of the coefficient of variation (CV), when driving to and fro, does not exceed 15 % calculated in accordance with EN 13739-2. This requirement shall be met for all stated conditions (e.g. working widths and fertilizer type) except for border spreading. The above r
49、equirement shall also be fulfilled for fertilizer distributors equipped with systems for flow rate regulation as mentioned in 4.7. 4.11.2 Border spreading It shall be possible to use the machine for border spreading, with or without extra equipment, with the aim that no fertilizer is spread out of the field. This requirement is fulfilled if the calculation of value Y according to 7.1.4 of EN 13739-2:2011 is less than 3,0 . At no point within the
