FR2507858A1 - AGRICULTURAL HARVESTING MACHINE, IN PARTICULAR COMBINE HARVESTER, COMPRISING A DEVICE FOR DETERMINING THE QUANTITY OF HARVESTED PRODUCT - Google Patents

Abstract

THE INVENTION RELATES TO AN AGRICULTURAL HARVESTING MACHINE, SUCH AS A COMBINE HARVESTER, IN WHICH THE WEIGHT OR THE QUANTITY OF THE HARVESTED PRODUCT 2 IS DETERMINED BY MEANS OF A CONTINUOUS DEVICE A, B, C, D OR EA MECHANICAL DRIVE, ELECTRIC, PNEUMATIC OR HYDRAULIC. THE DEVICE IS APPLICABLE TO COMBINE HARVESTS.

Description

The present invention relates to a machine

  agricultural harvest, in particular to a combine harvester

  threshers in order to perfect or complete the operation in such a way that the farmer can at any time check exactly the quantity of

coltée on one or the other field.

  The harvesting of cereals for example, takes place, as

  as is known, more than 90% of them with reapers

  threshers which collect in bulk the beaten and cleaned grain in a container placed on the combine and which, depending on the amount accumulated, transshipping the grain from time to time, for example mechanically or pneumatically, on

  prepared motor vehicles or their trailers.

  realties transhipped and whose weight has not yet been determined arrive in most cases immediately

  on the agricultural market or in cooperatives' silos.

  which determine by weighing the weight of the quantity of

  cereals delivered and then perform the calculation.

  The farmer dries up that producer who is the

  more often in a hurry by the weather during the harvest -

  considers this process disadvantageous and considers that it has the legal right to be able to determine the weight of the harvested product it places on the market.

  valid for the case where the product harvested does not arrive

  market, but is stored, so that appropriate arrangements are essential.

  for the purpose of satisfying the above-mentioned desire of the farmers.

  The harvesting machine according to the invention here a combine is characterized by the fact that the

  weight or quantity of product harvested may be

  mined before or during transhipment.

  Figure 1 is a schematic representation of the various possibilities of execution of the invention;

  Figure 2 is a side view of a combine harvester

  thresher equipped with a balance attached to the collecting container

tor;

  Figure 3 a side view of a combine harvester

  threshing machine whose collecting container is equipped with an evacuation screw followed by a balance; Figure 4 shows details and layout of a mechanical meter;

  Figure 5 is a view similar to that of the

  Figure 4, but showing an electrically operated meter

that or electronic.

  As best seen by the representation

  schematic of Figure 1, different possibilities have been

  the place where, on a combine harvester 1, the scale provided for according to the invention

  and who weighs the harvested product 2 or determines its weight

  canically or electronically and saves it, before

  the product arrives for example in a trailer 3.

  The combine harvester 1 presents, essential-

  in a known manner, a drum 4 which cleans and transports

  the harvested product 2, an elevator 6 and a collector

  8 and finally, an evacuation screw or an evacuation device 9, 9 'where the harvested product arrives on the

  loading area of the trailer 3.

  According to an example of preferential execution of the in-

  vention, the balance is provided directly in the region

  drum 4 and the elevator 6 Another possibility is

  would be to have a balance b at the exit of the elevator 6

  from which the harvested product 2 flows directly into the

  container 8 or is transmitted to a trans-

  carrier 7 mounted as additional equipment and from which

  it arrives at the collecting container 8 from a position

  higher, a scale c that can be placed directly

  at the exit of the auger 7 These scales or weighing devices can be installed on

  the combine harvester as soon as it is manufactured, without

  noticeably the price, they can be added after

  coup or be delivered after the fact as additional equipment

  It is also conceivable to have a balance d, provided according to the invention, in the region of the outlet opening of the collecting container 8 or to have a balance e at the discharge opening of the screw evacuation or evacuation device 9 from o the harvested product is brought for example to the trailer 3.

  Since the evacuation of the receptacle

  8 must be done within two seconds

  minutes, it would be necessary in the region of

  lances d and e, is provided a very high-speed balance.

  In the region of balances a, b and c, it is

  during the threshing process, a slight uniform grain flow, which could be measured with

  a continuous balance of cereals of commercial type, relatively

small.

  It is also particularly advantageous to use

  rubber conveyor belts with crampons and below which a

electronic weighing.

  For the after-the-fact equipment of harvesters

  threshers, the arrangement of the balance c to the

  collector container 8 is particularly suitable and, by means of a shorter screw conveyor, which can

  be driven electrically, hydraulically or di-

  the weighing cereals are transported upwards, from the elevator provided for the balance c, so that the

  quantities harvested are weighed.

  Normally, weighing machines of the type men-

  are equipped with a meter, so that each quantity

  collected or each daily yield can be read and

  noted from the driver's seat, regardless of the

  cereals, since only the effective weight is retained. In a more sophisticated mode of execution,

  corresponding quantities could even be printed.

  Another possibility to determine the harvested cereals (see in particular Figures 4 and 5) would consist of

  also to consider that the measure is ensured by the evaluation screw.

  cuation 9, the quantity that can be determined by counting

  number of turns of the screw, taking into account the weight

  tolitre With a conversion chart or calculator for the most diverse kinds of cereals, we multiply by the number of revolutions counted and we can read very exactly the quantity harvested to determine exactly

  the weight, when it comes to different qualities of cer-

  ales, it is necessary first to carry out a weighing test or

control of different kinds.

  If we incorporate sensors or feelers, we can only count the turns when

  the screw 9 is filled with harvested product 2.
