Definitions

  • the present invention is concerned with a container in accordance with the preamble of claim 1.
  • the container comprises a container body whose opposite ends are parallel to each other and are connected by walls, a mat or belt having a width substantially equal to the width of the container walls fitted between the ends of the container, one end of the said mat or belt being, by means of an attaching member, attached to the wall at the top portion of the container.
  • a container placed, e.g., on a railway wagon and emptied through the bottom onto a road transportation vehicle, such as onto the truckbed of a lorry or onto a tractor trailer
  • a conveyor is required, such as a belt or screw conveyor, in order to carry the material out of the discharge opening to the loading point. If the container is shifted out of its position in order to facilitate the loading, this may take place either in the lateral direction or in the vertical direction.
  • an auxiliary bridge is required above the platform, as well as a power gear for shifting the container.
  • a particular lifting device is required, e.g., a hydraulic lifting device.
  • an apparatus for discharging a flat-bottomed container such as a silo, which is used forthe storage of flowable granular materials.
  • the apparatus comprises a container body whose opposite ends are parallel to each other and are connected by walls, a mat or belt which is flexible in the longitudinal direction and one of whose ends is connected between the ends in the top portion of the container body by means of an attaching member, the width of the mat being substantially equal to the width of the container walls.
  • deformation of the mat is by means of pressurized air introduced between said mat and the container body to discharge the contents of the container whereas supplementary means are provided to restore the mat in the condition in which the container is being filled.
  • the object of the present invention is to eliminate the drawbacks present in the prior-art solu- ' tions and to provide a container bf an entirely novel type for the transportation, discharge and dosage of readily clodding granular and floury material.
  • the invention is based on the idea that the material is enclosed, in the container, from the bottom and from two opposite sides, by a flexible mat or belt.
  • the material in the container is carried along with the mat, and it can be discharged readily through the top portion. It is important that the mat is all the time pressed definitely tightly against the other two sides, whereby a leakage of the material between the edges of the mat and the said sides is prevented.
  • the mat is rigid in the lateral direction, that the other end of the mat is, in the top portion of the container body, attached to a roll, whose axis is parallel to the walls of the container body and whose length is substantially equal to the width of the walls, that for the purpose of rotating the roll, the container comprises disconnectable drive gear and ratchet locking members, and that there is a gate in the top portion of the container body for filling and discharge of the material.
  • such an attaching member consists of a second rotable roll.
  • the mat is coated with a material or material layer promoting the friction.
  • the mat is pressed by the effect of the weight of the material against the side and bottom walls of the container structure.
  • the granular of floury material is carried, by the effect of friction between the mat and the material, along with the mat into the top portion of the container, from where it can be passed out of the container, e.g., by means of a glide chute.
  • the container in accordance with the invention is mainly characterized in what is stated in the characterizing part of claim 1.
  • the equipment is suitable for bulk fertilizer, grain, talc, etc. inconvenient granular and floury materials.
  • the equipment in accordance with the invention is simple, and it can be accomplished in practice by using inexpensive solutions of equipment.
  • the equipment can be used in most varying objects of use, its construction is very well suitable, e.g., for the dosage of fertilizers straight onto the field.
  • the material in the container cannot be clodded, but it is mixed automatically when the material is being discharged from the container.
  • the requirement of cleaning of the container is low, because, in use, the mat automatically cleans the glide faces at the ends of the container.
  • the material in which both ends of the mat are attached to rolls, the material can be discharged to both sides of the container, even simultaneously if so desired.
  • the mixing of the material in the container is in this case even more efficient.
  • the construction of the container shown in Fig. 1 is as follows:
  • the container part consists of parallel plane walls 1 and 1', of ends 15, and of a bottom 2.
  • a rotary roll 3 is mounted between the end 1 and the opposite end 1', in the top portion of the container.
  • the end 4 of the roll is connected to the drive gear 6 by means of a suitable mechanism 5.
  • the drive gear 6 may be a hydraulic cylinder, hydraulic motor, or an equivalent motor.
  • the end 4 of the roll is also provided with an appropriate locking device 7, by whose means it can be ensured that the roll revolves in the desired direction only.
  • a flexible mat 8, which is, at the same time, rigid and robust in the transverse direction, is attached to the roll 3, the said mat being coated with a layer increasing the friction.
  • the attaching member 9 may consist, e.g., of a metal bar attached to the wall.
  • the attaching member 9 may consist, e.g., of a metal bar attached to the wall.
  • the gate 10 opening upwards, for the filling and discharge of the material.
  • a plate 11 of a width equal to the wall is mounted, which plate is directed diagonally upwards towards the roll 3 and at whose end there is a scraper edge 12, which may be, e.g., similar to a rubber rib or brush and which is pressed against the roll diagonally from underneath.
  • a container as described above of a volume of about 5 m 3 , was made of plywood boards reinforced by means of appropriate steel frameworks.
  • the length of the container was 2.5 m, width 1.2 m, and its height from the bottom to the top level of the roll 2 m.
  • As the mat was used a rubber mat with canvas reinforcement, of a thickness of 5 mm.
  • the end walls were coated with a rubber layer in order to improve the sealing between the mat and the walls.
  • As the drive gear was used a hydraulic cylinder, and as the connection between the hydraulic cylinder and the roll end was used a ratchet device.
  • the container operates as follows: When the container is empty, the mat 8 is advantageously completely wound on the roll 3 over its entire length, except for the portion remaining between the roll 3 and the attaching member 9.
  • the roll 3 When the container is being filled with a granular or floury material, such as bulk fertilizer, the roll 3 is disconnected from the drive gear 6 and from the locking device 7, whereat the mat 8 is unwound off the roll 3 and pressed by the weight of the material to be filled towards the bottom 2 and the walls 1 and 1'. Owing to the construction of the mat8, rigid in the transverse direction, no material can flow between the edges of the mat 3 and the ends 15 onto the bottom 2. When the quantity of the material to be loaded rises to the level of the roll 3, filling is stopped and the locking system 7 is switched on the roll 3.
  • the drive gear 6 When material is to be discharged from the container, the drive gear 6 is connected to the roll 3, the gate 10 is opened, and the mat 8 starts being wound onto the roll 3 by means of the drive gear 6. Thereat material follows along with the mat onto the roll 3, from where it can be guided to the desired point via the plate 11 and by means of a possible additional glide chute, if any.
  • the scraper edge 12 removes any material possibly adhering to the mat 3 off the mat. By dosing in this way, any desired quantity of granular or floury material can be discharged from the container.
  • FIG 4 shows an alternative, preferred embodiment of the container construction in accordance with the invention.
  • the attaching member now consists of a second roll 9, which is similar to the said first roll 3 and parallel to the said latter roll.
  • the second roll 9 is installed in a way corresponding to the first roll 3 and is preferably placed at the same level with it.
  • the second roll 9 may be provided with a separate drive gear, or the same drive gear may be used for rotating it as is used for rotating the first roll 3.
  • the distance between the rolls is here preferably approximately equal to their length, i.e. the opening defined by the opposite ends 15 and by the rolls 3 and 9 fitted between them is substantially of square shape.
  • a rigidifying member 14 in the present case a metal bar, is fitted in order to reinforce the construction of the container.
  • the length of the mat must be so large that at least a length corresponding .to the distance of the rolls 3 and 9 is at all times wound on any one of the rolls.
  • a container in accordance with the invention was prepared, whose dimensions were equal to those of the preceding example.
  • the second roll (diameter 14 cm) was placed at the same level as the first roll, so that the distance between them was equal to their length, i.e. 1.2 m.
  • edges of the ⁇ belt can be provided with packing means known per se in order to keep the edges constantly in contact with the end walls of the container during operation.
  • packing means may comprise resilient hoses filled with a gas, such as pressurized air, or an uncongealable liquid, such as hydraulic oil.

Abstract

Le container comprend une partie de conteneur dont les extrémités opposées (15) sont parallèles entre elles, un tapis (8) adapté à l'intérieur du conteneur, lequel tapis est flexible dans le sens longitudinal et rigide dans le sens latéral et qui est fixé à ses deux extrémités à des cylindres parallèles (3, 9) placés sur les côtés opposés dans la partie supérieure du conteneur, ainsi que des portes (10) de remplissage et de décharge du matériau. A l'aide d'un engrenage d'entraînement (6) qui fait tourner l'un des cylindres, p.ex. le cylindre (3), il est possible d'enrouler le tapis (8) sur le cylindre (3) et de décharger le matériau du conteneur du côté du cylindre (3) en rotation. Lors de l'étape finale de la décharge, le tapis (8) peut être enroulé sur le second cylindre (9), de telle sorte que l'on obtient un fonctionnement du type à bande transporteuse et même la dernière quantité de matériau restant peut être déchargée du conteneur.
