SU2829A1 - Adaptation to automatic scales for weighing grain residues - Google Patents

Description

The proposed fixture is designed to determine the remaining grain in the bucket, not the containers.

FIG. 1 shows the device, FIG. 2 shows its modification and in FIG. 3 - detenting device.

The fixture is a balance sheet, which consists of an additional rocker D with a fulcrum H, a short arm / O of which is connected to the chamber 12 for the tare 7 of the main rocker, and the long arm 9 carries a roller 6

complex weight 2. The strength of the body of the tare (weight) 7 acts through the prism 8 on the shoulder 10. The long arm 9 is equipped with a scale 1, the division of which begins from the side of the fulcrum. Complicated gear 2 consists of a frame 75 with a scale of 3, dividing which goes in the opposite direction to that of shoulder scale D. On scale 3 there is a mobile load 4, equipped in turn with a mobile load — a rail 5 (replaces the small weighting) with divisions going in the same direction as on shoulder D.

To weigh the grain of a certain nature, as many weights are placed in the chamber 12 as is necessary to balance a full grain bucket of the given nature. Then, the gir 2 moves on a scale of 7 until it balances the camera 72 s with the glands placed there, at which the gir 4 and the rail 5 should stand on zero. Then, noting the readings under these conditions, the weights 2 on the scale of /, the device are isolated from the action of the tare 7, and the scales are set in motion. At the end of the operation, it is necessary to determine the amount of grain remaining in the ladle, which is not in: its state to be turned over. Then include the device and put the weight 2 on the previously noted division. The equilibrium of the device is not obtained, for, on the one hand, container 7 acts on the balance sheet, and on the other hand, dash 2 is complicated in the position in which it balanced the container 7, and also the remainder of the grain. This residue must be determined. To do this, from the sum of the forces acting on the device from the opposite container 7, subtract a quantity equal to the weight of the remainder of the grain; This can be done by reducing the moment of a complex weight 2 by an amount equal to the weight of the grain in the ladle. For this, it is necessary to reduce the moment of the weight 2 by moving the additional load 4 and, if necessary, the rail 5 up to the position at which the balance is restored. The additional load 4 and rake 5 will show by straightforward reading how much grain is in the bucket. Consequently, automatic scales fitted with this fixture show by direct reading the amount of grain left in the ladle (it does not turn it over).

B. instead of the device of a special complex weight 2, it is possible, if the scale system allows, to arrange the scale movable in a specially arranged nest 13 so that its length can be changed, i.e. distance of the extreme division of the scale from the main prism of the device. Then the complex weight 2 (fig. 1) with the additional scale 3, weight 4 and rail 5 becomes unnecessary. The load 4 (fig. 2) with the rail 5 is placed directly on the scale 7 of the rocker arm. The scale 7 is i-radiated in the reverse direction and division starts from the end of the arm 9 of the rocker arm C, while the prism has a division corresponding to the weight of the grain of the greatest nature with a full bucket. The action of the device is similar to the action in the first version. The scale 7 moves in its nest 13 until it balances the tare 7, which corresponds to the nature of the weighed grain, and the weight 4 and the lath 5 must stand on their zero divisions and secure in this position with the locking device 14 providing its stillness in the nest. To determine the remaining grain after switching on, the device 4 moves the load 4 and the rail 5 from zero to the main prism 7 / until the tare 7 balances them. The readings of the load 4 and the slats 5 indicate the weight of the grain in the bucket.
