Description

The tray bays are made upwardly protruding. In the process of moving the fruit on a wavy inclined surface

the tray speed of their movement is reduced, and the flow of fruit is evenly distributed throughout the container. 2 hp f-ly, b silt.

The invention relates to an agricultural technique - and can be used for storing vegetables and potatoes.

The purpose of the invention is to reduce damage to fruits and to reduce material consumption by reducing the speed of fruits with a smaller number of damping elements per unit height of descent of fruits. .

Fig 1 shows a diagram of the device; in fig. 2 is a view A of FIG. 1, the top tray with parallel protrusions; on fiR 3 - the same, with non-parallel protrusions; in fig. 4-6 is a section BB in FIG. 2 (section of the tray with wavy, rectangular and trapezoidal protrusions on the working surface, respectively.

A device for placing fruits into a container contains a feeding conveyor 1, a lifting and lowering fruit compartment, including Bepxj nu 2 and a bottom, 3 frames, a tray 4 of the upper frame, trays 5 between the half-frames 6. The trays are made of an elastic material (rubber). On the working surface of the tray, at least the upper frame, there are protrusions 7, extending downward from the interface line relative to the tray with the frame, having, for example, a wavy, rectangular or trapezoidal profile and located symmetrically relative to the longitudinal axis of the tray. dTO creates guides for moving fruits, ensuring uniform distribution of the fruits throughout the container.

With small sizes of fruits and low speed of their falling from the conveyor to the upper tray, the protrusions 7 are made only on the upper tray, and they are parallel to each other.

With significant sizes of fruits and average speeds of their falling on the upper tray, a more effective projection scheme can be applied with linearly decreasing angles between them in the direction from the junction line of the tray with the corresponding frame to the bottom of the tray.

At significant speeds of falling fruits from the conveyor, it is most expedient to carry out the protrusions 7 with a linear decrease in the angle between them in the direction from the upper tray to the lower ones, i.e. on each subsequent tray (not shown). The angles between the protrusions are in the range of 40-160, the pitch between them is one order with the average linear dimensions of the fruits, the height of the protrusions is 0.05. 0.3 of this value. Wavy protrusions 7 can be made by stamping in the manufacture of trays. The angles of inclination of the trays to the horizontal plane can be equal to 45-70 °, which is determined experimentally by assessing the quality of the damaged fruit and the capacity of the device for the various options for the location of the trays.

0 The device comprises a mechanism for raising and lowering the lower frame 3 associated with it by means of flexible grids 9 which are wound onto a drum 10.

The device works as follows. Fruits falling on trays, elastically deform the elastic material of the upper tray. At the same time, due to the deformation of the elasto-elastic material, the dynamic components of the load on the surface of the ovoid and vertical components of the velocity are effectively reduced. During the subsequent movement of the fruit along the wavy inclined working surface of the tray, the speed of movement of the fruit decreases or practically remains constant, and the flow of fruit 35 is evenly distributed throughout the volume of the container. Thus, with increased distances between the trays at the upper frame, the vertical component of the speed of movement of fruits at the exit from the device is insignificant, which ensures an increased reliability of their preservation at a given throughput, reduced material consumption and laboriousness of manufacturing the device.
