Implementation of the invention.

The bulk materials dispenser is a filling table 1 made in the form of a rectangular sheet of hard, durable material (for example, steel) whose opposite width sides are fixed on horizontally located load-bearing beams 2, the opposite ends of which are fixed on support posts 3. On the upper plane of the sides of the filling machine of table 1, rails 4 are mounted along sides opposite in length, the length of which is not less than the distance between the back side of the loading opening 9 and the front side of the unloading opening 5.

In the front part of the filling table 1 there is an unloading opening 5, which is a rectangular hole with a parallelepiped without bases mounted along its perimeter, to the lower plane of the filling table 1. On the upper plane of the filling table 1 there is a filling box 6, which is a parallelepiped without bases, on two opposite side faces of which wheels 7 are mounted, designed to roll on the surface of the rails 4. The wheels 7 and rails 4 are made with the possibility of horizontal movement of the filling box 6 between the loading opening 9 and unloading opening 5.

The height of the rails 4 and the height of the attachment of the wheels 7 to the sides of the filling box 6 are designed to provide a gap between the lower ribs of the filling box 6 and the upper plane of the filling table 1 of no more than 10 mm.

Above the filling table 1, on support posts 3, there is a dispensing container 8, which is an inverted pyramid without a base, to the truncated top of which is mounted a loading opening 9, made in the form of a parallelepiped without bases.

The perimeters of the loading opening 9, the unloading opening 5 and the filling box 6 are made proportionate.

The distance between the horizontal projection of the front side of the loading opening 9 and the horizontal projection of the rear side of the unloading opening 5 is not less than the length of the filling box 6.

In the front part of the rail 4, front limiters 10 are mounted, designed to limit the movement of the filling box 6 in a position where its perimeter is coaxial with the perimeter of the unloading opening 5. In the rear part of the rail 4, rear limiters 11 are mounted, designed to limit the movement of the filling box 6 in a position when its perimeter is coaxial with the perimeter of the loading opening 9.

Mounted on top of the packing box 6 is a locking sheet 12, which is a rectangular sheet of hard, durable material (for example, metal), the width of which is greater than the width of the packing box 6, and the length is not less than the distance between the rear sides of the horizontal projections of the loading opening 9 and the unloading opening 5, made with the possibility of closing the loading opening 9 simultaneously with the movement of the filling box 6 in the direction of the unloading opening 5. A hole is made along the line of contact of the plane of the locking sheet 12 with the filling box 6 (not shown in the figures).

Along the middle part of the filling table 1 along its sides opposite in length, distal to the rails 4, stands 13 are mounted, on the upper ends of which rollers 14 are mounted, touching the lower plane of the locking sheet 12. The rollers 14 are made with the ability to move the locking sheet 12 along them when moving packing box 6 from the loading position to the unloading position and back. The height of the racks 13 with rollers 14 is designed to provide a gap between the upper plane of the locking sheet 12 and the lower ribs of the unloading opening 5, no more than 10 mm.

The filling box 6 is connected to a motor (not shown in the figures), configured to ensure reciprocating movement of the filling box 6 along the filling table 1, between the loading opening 9 and the unloading opening 5.

In various embodiments, the connection of the engine (not shown in the figures) with the packaging box 6 is made in the form of a friction or gear, or belt, or chain, or worm drive.

In one embodiment, the unloading opening 5, the packaging box 6, the loading opening 9, can be made in the form of other volumetric polygons without bases, or in the form of a cylinder without bases, or in the form of an elliptical cylinder without bases.

In one embodiment, the internal perimeter of the filling box 6 can be changed to change its internal volume.

The bulk materials dispenser operates as follows.

The filling box 6 is in the extreme forward position when the wheels 7 rest against the front stops 10, and the loading opening 9 is blocked by a locking sheet 12. Bulk material (not shown in the figures) to be dosed is loaded into the dispensing container 8, the engine is started (not shown in the figures) shown), which moves the packaging box 6 with the locking sheet 12 mounted on it to the rearmost position, when the wheels 7 rest against the rear stops 11, the packaging box 6 moves by rolling the wheels 7 along the rails 4. During movement to the rearmost position of the packaging box 6 with a locking sheet 12, the loading opening 9 opens and bulk material (not shown in the figures) pours out of it into the volume of the filling box 6, the lower part of which is limited by the plane of the filling table 1. After filling the volume of the filling box 6 with bulk material (not shown in the figures shown) the dosing cycle begins, during which the motor (not shown in the figures) moves the filling box 6 with the locking sheet 12 mounted on it to the extreme forward position, when the wheels 7 rest against the front stops 10. During the movement of the filling box 6 to the extreme front position, the loading opening 9 is gradually blocked by the locking sheet 12, and when the front edge of the filling box 6 crosses the rear edge of the unloading opening 5, the bulk material and the volume of the filling box 6 are unloaded into a receiving container (not indicated in the figures). After the volume of the filling box 6 is emptied, the engine (not shown in the figures) moves the filling box 6 with the locking sheet 12 mounted on it to the rearmost position when the wheels 7 rest against the rear stops 11. During the movement of the packaging box 6 to the rearmost position, gradual alignment of the perimeter of the loading opening 9 with the perimeter of the filling box 6, as a result of which the volume of the filling box 6 is filled with bulk material (not shown in the figures) and the dosing cycle ends. The result of one dosing cycle is the movement of bulk material (not shown in the figures) from the dispensing container 8 to the receiving container (not indicated in the figures) in a volume equal to the volume of the filling box 6.

The technical result - increasing the reliability of the bulk materials dispenser, is achieved due to the fact that the bulk materials dispenser contains a dispensing container 8 fixed on vertical supports 3, in the lower part of which there is a loading opening 9, under which, on supporting beams 2, the opposite ends of which are fixed on vertical supports 3, a horizontally located filling table 1 is mounted in the front part of which there is an unloading opening 5, on the upper plane of the filling table 1 there is a filling box 6, the perimeters of the loading opening 9, the unloading opening 5 and the filling box 6 are made proportional, from top to rear of the filling box 6, a locking sheet 12 is mounted, the width of which is greater than the width of the filling box 6, and the length is not less than the distance between the rear sides of the horizontal projections of the loading opening 9 and the unloading opening 5; on the upper plane of the filling table 1, rails 4 are mounted along its sides; On the sides of the filling box 6, wheels 7 are mounted, in the middle part of the filling table along its sides, distal to the rails 4, racks 13 are mounted, on the upper ends of which rollers 14 are mounted, touching the lower plane of the locking sheet 12, the distance between the upper plane of the locking sheet 12 and the lower edge of the loading opening 9 is no more than 10 mm, the distance between the upper plane of the filling table 1 and the lower edge of the filling box 6 is no more than 10 mm.

The presence of rails 4 on the surface of the filling table 1, as well as the presence of wheels 7 at the filling box 6, designed to roll on rails 4, reduces the friction force that occurs during the reciprocating movements of the filling box 6 along the surface of the filling table 1, and reduces mechanical wear the bottom of the filling box 6 and the surface of the filling table 1, which increases the reliability of the design. In addition, the distance between the bottom of the filling box 6 and the upper plane of the filling table 1, no more than 10 mm, prevents bulk materials (not shown in the figures) from spilling out of the filling box 6, when it moves to the unloading opening 5, and getting into the moving parts of the structure, thus reducing mechanical wear on moving parts of the structure and increasing the reliability of the structure.

The presence of racks 13 mounted in the middle part of the filling table 1 along its sides, distal to the rails 4, makes it possible to support the locking sheet 12 at a height that provides a distance between the upper plane of the locking sheet 12 and the lower edge of the loading opening 9 of no more than 10 mm, which prevents pouring out of the loading opening 9 bulk materials (not shown in the figures), when moving the filling box 6 to the unloading opening 5, and getting them into the moving parts of the structure, thus reducing the mechanical wear of the moving parts of the structure, and increasing the reliability of the structure. In addition, the presence of rollers 14 at the upper ends of the racks 13 makes it possible to convert the sliding friction force that occurs when moving the locking sheet 12 into rolling friction, which reduces the mechanical wear of the locking sheet 12 and increases the reliability of the structure.

During full-scale tests carried out in 2023, a prototype and four copies of the claimed device were manufactured and tested with different distances between the lower edge of the loading opening 9 and the upper plane of the locking sheet 12, and between the lower part of the filling box 6 and the upper plane of the filling table 1. In the first In one copy, these distances were made with a value of 1 mm, in the second copy with a value of 5 mm, in the third copy with a value of 10 mm, in the fourth copy with a value of 12 mm. As a result of testing, it was found that the number of dosing cycles before failure in the first copy of the claimed device turned out to be 35% greater than in the prototype, in the second copy of the claimed device - by 28%, in the third copy - by 11%, respectively. For the fourth copy of the claimed device, the time to failure turned out to be less than that of the prototype, due to the fact that when the distances between the lower edge of the loading opening and the upper plane of the locking sheet, or between the lower part of the filling box and the upper plane of the filling table, are more than 10 mm, the dispensed material (river sand was used during the experiment) spilling out of the loading opening 9 or filling box 1 led to blocking of the moving parts of the structure.

Although the technical solution has been described in detail for purposes of illustration based on embodiments currently considered to be the most practical and preferred, it should be understood that such details are solely for the stated purpose, and the utility model is not limited to the disclosed embodiments, but covers equivalent connection options that do not go beyond the scope of the claims of the utility model formula. For example, it should be understood that the utility model contemplates that, to the extent possible, one or more features of any embodiment may be combined with one or more features of any other embodiment.
