Description

The invention relates to metering devices for bulk materials and can be used in animal feed, chemical, food, construction and other industries.

A well-known hopper-feeder with an outlet slot (autosw. No. 272891; G01F 11/26, 1970), mounted on a rotary axis outside the center of gravity of the hopper and equipped with movable weights associated with the rotary axis of the hopper using a gear rack and wheels, is one of which are mounted on the axis of the hopper.

The disadvantages of the known device are the dosing of only one component and the possibility of jamming of the slide gate valve in the guides due to clogging of their particles of material.

Closest to the invention is the “Vibrating Feeder” selected as a prototype (ed. St. No. 1720944; B65D 88/66, 1992), comprising a sectioned housing with an outlet pipe, a loading device, a distribution cone with a vibration actuator and adjustable shutters for dispensing doses of the component, while the casing is divided into sections by radial partitions and provided with visors fixed in each section above the distribution cone, adjustable shutters are mounted in each section on the distribution cone, and the loading risposoblenie taken at the top of the housing and consists of a funnel mounted with the possibility of rotation to an outlet located eccentrically and above the convex fortified sieves connected with the distributor cone by a rod.

The disadvantages of the known device are low dispensing efficiency and productivity due to the large limited travel of the adjustable dampers in the cone guides, as well as the complexity of the design and low reliability of the dispenser.

The purpose of the invention is to increase the efficiency of the dosing process of various bulk components simultaneously in the required proportions, to increase the productivity of the installation, as well as to increase the reliability of its operation.

This goal is achieved by the fact that the casing is box-shaped in the form of a wedge and spring-loaded, activators are installed on the inner beveled side of the casing, and a vibration drive is installed on the external side, in addition, a plate with holes matching the outlet windows of the casing sections is vertically mounted and guide grooves in which adjustable shutters are mounted with the possibility of movement in the vertical plane, connected to sliders moving in these grooves and having gear racks located I engaged with the gear wheels, which fit onto the wheel drive shaft. At the same time, adjustable flaps are made with cutting ends and are mounted in sliders with the possibility of fixation.

According to the information available to the authors, the set of essential features that guarantee the essence of the claimed invention is not known and should not be explicitly for a specialist from the prior art, which allows us to conclude that the invention meets the criteria of "novelty" and "inventive step".

The set of essential features characterizing the invention, in principle, can be repeatedly used in agriculture, animal feed, chemical, food, construction and other industries for dispensing bulk materials and ensures the achievement of the goal - increasing the efficiency of the process of dispensing several bulk components simultaneously in the required proportions , increasing the productivity of the installation, as well as improving the reliability of its operation, and allows us to conclude zobreteniya criterion of "industrial applicability".

The essence of the proposed solution is illustrated by the drawing, where Fig. 1 shows a vibration-gravity dispenser, a general view, in Fig. 2 - section AA in Fig. 1, and in Fig. 3 - view B in Fig. 1.

The vibration-gravity dispenser (Fig. 1) consists of a box-shaped body 1 in the form of a wedge with sections mounted by means of springs 2 on the frame 3 supports. Activators 14 are installed on the sloped inner side of the body 1 (Fig. 2), and on the outside - inertial vibration exciter 15. A plate 12 with holes 17 (FIG. 3) vertically mounted on the front wall of the housing 1 coincides with the outlet windows 16 of the housing sections and guide grooves 13 in which the adjustable shutters 11 and sliders 9 having gears move in a vertical plane e slats 8. The adjustable valve 11 installed in the slides 9 with the possibility of movement in the vertical plane, connected with the sliders 9 by means of clamps 10 and formed with cutting ends. The gear racks 8 of the sliders 9 are meshed with the gears 4, which are mounted on the shaft 17 of the manual drive 5. The shaft 17 of the gears 4 is mounted in the bearing bearings 6 attached to the housing 1.

Vibration-gravity dispenser works as follows. The sections of the housing 1 are filled with bulk components in the required ratio. Depending on the required ratio of components before loading the hopper, the opening size of the outlet windows is first set using the shutters 11, which are adjusted in the guide grooves 13 of the plate 12 for the required stroke with the clamps 10 in the sliders 9. The adjustable shutters 11 and the sliders 9 are moved together in the same guide grooves 13. The sliders 9 are on the same horizontal level, as well as the gears 4 on the shaft 17 of the manual drive 5. When the inertial vibration exciter 15 is turned on, the housing vibrates intensively and 1 on the frame supports due to the elastic ties - springs 2. From the vibrating surface of the housing, the oscillatory movements are transmitted to the activators 14. The activators 14 bring the loose components in the housing sections into a state of “fluidization”, especially intensively on the sloping side. The state of "fluidization" eliminates the compilation of bulk materials in the housing, their flowability increases, which positively affects their uniform flow. The flaps 11 open simultaneously when the handle of the manual actuator 5 is moved upward, which is connected to the wheel shaft 4. The gears 4 rotate and raise the gear rack 8 together with the sliders 9 and the flaps 11 in the guide grooves 13 of the plate 12. When the flaps open, the bulk flows uniformly at the same time. components from sections of the housing 1 through the outlet windows 16. To close the shutters 11, you must lower the handle of the manual actuator 5 down. Manual drive 5 has a travel lock.

The installation of adjustable shutters 11 in the sliders 9 and guide grooves 13 of the plate 12 with the possibility of their fixation and movement in a vertical plane allows you to adjust the flow of various components from each section in the required ratio, as well as to increase the productivity of the installation by increasing the size of the outlet windows, which may be limited by size the front wall with the plate 12. Adjustable shutters 11 are made with cutting ends to prevent them from jamming in the guide grooves 13, which occurs due to clogging of their parts titsami material. The above conditions positively affect the reliability of the installation.

The technical and economic effect is achieved by bringing the bulk components into a “fluidization” state in a multi-section box-shaped case in the form of a wedge, regulating the rate of component delivery over a wide range through the use of dampers, which generally affects the efficiency of the dosing process of different bulk components simultaneously in the required proportions, increasing the productivity of the installation and increasing its reliability.
