The closest in technical essence is a vibration conveyor (copyright certificate No. 1084202 of 04/07/1984), including a load-carrying trough, a support frame, a drive, a vibro-shock mechanism.

The disadvantages of the given vibration conveyor are:

1) there is no energy-efficient balancing of inertial forces;

2) high energy costs for transportation of material;

3) there is no device for regulating the thickness of the layer of transported material;

4) The length of the vibratory conveyor is of limited value.

The objective of the invention is to increase the efficiency and economy of the process of transportation and distribution of various bulk materials, including full feed mixtures in animal husbandry.

The problem is solved in that in the proposed stationary swinging conveyor containing a tray, pendants, a two-eccentric shaft with an electric motor, a connecting rod, a signaling device for filling the tray with material at the end of the conveyor, an additional second section is similar in design, the tray of each section is made of a movable bottom and fixed sidewalls on which the device for controlling the thickness of the layer, the transported material is mounted, and the modular sectional design of the stationary sectional pump This conveyor allows you to move the material to almost any distance.

New significant features:

1) the sectional design of the stationary swinging conveyor driven by a two-eccentric shaft in mutually opposite directions, each of the two sections allows to obtain energy-efficient balancing of inertial forces;

2) the vibration drive of only the bottom of the trays, together with the transported material with fixed sidewalls, can reduce the energy costs of transportation with simplifying the design of the proposed conveyor;

3) a mechanism for regulating the thickness of the layer of material mounted on the axes of the fixed sidewalls can withstand animal feeding diets with varying volume and composition of the PCB;

4) an unlimited number of two-section swinging modules, conveyor allows you to transport material to almost any distance.

The listed new essential features are sufficient in all cases to which the requested scope of legal protection applies.

Identified distinguishing features in conjunction with the known provide a technical result.

Due to the installation of fixed side walls at the load-carrying tray made of material with a low coefficient of sliding friction, and a moving bottom, energy costs for moving the material are reduced. Balancing the swinging masses of the conveyor is carried out by driving the sections in motion in opposite directions from the eccentrics located on the oscillating shaft. Additionally, inertia forces are balanced by elastic suspensions. The productivity of the conveyor depends on its kinematic mode, the width of the tray, the angle of the directions of oscillation and the angle of inclination of the bottom of the tray to the horizontal, on the physicomechanical properties of the transported material, and the sliding friction coefficient of the material of the fixed sidewalls. The mechanism mounted on the axes of the sidewalls allows you to adjust the thickness of the layer of transported material both over its entire length and in its different sections.

Figure 1 shows a stationary sectional swinging conveyor, General view; figure 2 is a section along aa (figure 1).

The swinging conveyor contains two sections 1 and 2, identical in design, in which the inertial forces are mutually balanced and are not transmitted to the base 3 of the fastening of the elastic suspensions 4 with brackets 5. However, better balancing is achieved by installing a two-eccentric shaft 6 between sections 1 and 2. Each section includes a tray 7, consisting of a swinging bottom 8 and fixed sidewalls 9, which are attached to the uprights 10. The swinging conveyor refers to a low-frequency machine in which the connecting rod 11 creates large disturbing forces at low Coy rotational speed double-eccentric shaft 6. In this case, the angle between the line of action of the connecting rod 11 and suspension brackets 4 in the middle position of the bottom 8 should be close to 90 °. The connecting rod 11 is pivotally connected to the brackets 5 with the help of silent blocks or rubber bushings, and on the other hand, with the shaft 6 using eccentric bushings on bearings. In the sidewalls 9, on the axes 12, two shoulders levers 13 of the mechanism for controlling the height of the layer of transported material are installed. On the lower part of the levers 13, valves 14 with weights 15 are fastened. A cable 16 is tensioned along the swinging conveyor 16 with stops 17 for the upper arms of the levers 13. The stops 17 limit the rotation of the valves 14. The cable 16 is fastened through the springs 18 to the adjusting levers 19. The end valve 14 is mounted the swivel conveyor fill indicator, which includes proximity sensors 20 and 21, controlled by a magnet 22 mounted on a lever 13. The bracket 23 with the sensors 20 and 21 is adjustable in height. The lower sensor 20 signals the filling of the swinging conveyor, and the upper sensor 21, if necessary, disconnects the drive on the shaft 6.

The swinging conveyor is designed for transporting and distributing various bulk materials, including PKS in animal husbandry. A modern tractor mixer-feeder cannot serve the maternity department of cattle due to violation of zootechnical requirements. For these purposes, we have proposed a swinging conveyor.

Stationary swinging conveyor operates as follows.

Feed through the feed hopper is fed into the tray 7 of section 1 from one end, which is located behind the wall of the maternity ward. The progressively moving masses of the conveyor are balanced by the installation of two sections swinging in antiphase. The bottoms are driven into swinging movements through the connecting rods 11 from the shaft 6, the eccentrics of which are offset by 180 °. Additionally, the inertia forces are balanced by elastic suspensions 4, which are attached to the brackets 5 at the tray 7 and at the base 3.

Simplification of the design of the conveyor due to the fixed sidewalls 9 on the uprights 10 can reduce the energy costs of transportation, since the oscillating and swinging movements receive only the bottom 8 together with the transported feed. Mounted on the axes 12 of the sidewalls 9, the mechanism for simultaneously controlling the thickness of the PCB layer along the entire length of the conveyor is controlled from levers 19, to which the cable 16 is attached with stops 17. They limit the turns of the two-arm levers 13. The valves 14 mounted on the bottom of the levers 13 are turned by the moving PCB after accumulating them in front of the valve with a given layer thickness. Distribution of the FCS on the conveyor is carried out by the formation of a planned layer thickness on its section in front of the selected valve 14, which is set by different masses of loads 15, and also by changing the load securing at a different radius from its center of gravity to axis 12.

After filling the conveyor with PKS or other material, lever 13 begins to rotate with a magnet 22 and with a valve 14. Magnet 22 includes sensors 20 and 21. From the lower sensor 20, light and sound signals are triggered when the conveyor is filled with PKS or other material. If necessary, the drive to the shaft 6 is disconnected from the upper sensor 21. The moment of the drive shutdown is controlled by the height-adjustable movement of the bracket 23 together with the sensors 20 and 21.

The process of transporting PCS is very simple, safe for animals and staff. Gas contamination of the maternity room, noise are eliminated and the optimum microclimate is ensured. The conveyor is characterized by low material consumption, does not occupy the useful area of the room, as it is installed instead of the feeder. It is easy to manage, has complete automation of the transportation and distribution process. The conveyor is easily self-cleaning of feed residues before the next distribution of PCB.

The choice of relatively soft dynamic parameters of the swinging conveyor allows to reduce the separation of the PCB during their distribution. The connecting rods 11 provide a productive movement of the PCB and other material in the tossing mode when the flight time of the moving particles is equal to the time of one revolution of the shaft 6. For the swing conveyor to work on the various transported material, it is advisable to adjust the speed of the shaft 6 by ± 25% of the nominal value.

An unlimited number of two-section modules of a stationary sectional swinging conveyor allows you to transport material to almost any distance.
