Abstract

The invention relates to the mechanization of agriculture and can be used in the mechanized purification of harvested potatoes from impurities with simultaneous sorting of it into fractions and the feeding of sorted potatoes into containers. The aim of the invention is to improve the sorting accuracy and the quality of cleaning potatoes from impurities, as well as to reduce product injuries by ensuring the minimum height of falling potatoes when unloading from the vehicle into the receiving bin. The potato sorter station contains a frame 1, a receiving bunker 2 with a peeler and a movable bottom 3 made in the form of a conveyor. The movable bottom 3 has a support 4 on the receiving side, which is installed with the possibility of changing its size in height. At the exit of the movable bottom 3, there is a cargo flow controller with a sensor, behind which, with the overlapping of the working bodies, a separator 8 of impurities is mounted, made in the form of a sifter conveyor, after which a sorting device 9 is installed. Under the separator 8 and sorting device 9, discharge conveyors 10 are installed. as the load platform tilts, the height of its exit part changes. This is detected by a height sensor, which sends a signal to the support 4 which is changing in height, by changing the height of which the minimum height of falling of potatoes from the vehicle to the moving bottom of hopper 2 is maintained. f-ly, 4 ill. sl C h | yu a

Description

The invention relates to the mechanization of agriculture and can be used with the mechanized purification of tires harvested from tires with simultaneous sorting into fractions and feeding sorted potatoes into containers.

The aim of the invention is to improve the sorting accuracy and the quality of cleaning potatoes from impurities, as well as to reduce product injury by ensuring the minimum height of its fall when unloaded from a vehicle into a receiving bin.

The goal is achieved by the fact that in order to ensure the minimum height of the fall of the potatoes when unloading from the vehicle into the receiving bunker, there is a height-adjustable support on the receiving side of the moving bottom of the bunker. An increase in the sorting accuracy is achieved due to the even distribution of potatoes over the entire surface of the working web by the attendant leveler and by uniformly feeding it to the working bodies by a cargo flow controller made in the form of a hinged-mounted damper with a sensor.

Improving the sorting accuracy is achieved due to the even distribution of potatoes over the entire surface of the working web by the attendant leveler and the even supply of potatoes to the working bodies by a cargo flow controller made in the form of a hinged damper with a sensor.

Improving the quality of cleaning from impurities is achieved by using an impurity separator made in the form of a sifting conveyor.

FIG. 1 shows a potato sorting point, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2

The potato sorter station contains a frame 1, on which the output part has a bunker 2, with a movable bottom 3, made in the form of a conveyor, which has a support 4 on the receiving side, installed with the possibility of changing its size in height. In the bunker above the movable bottom an attendant spreader 5 is installed, and at the exit of the movable bottom there is a cargo flow controller b with sensor 7 (Fig. 4), after which, with the overlapping of the working bodies, an impurity separator 8 is installed, made in the form of a sifter conveyor, after The sorting device 9 is installed by overlapping the working bodies, and the discharge conveyors 10 are installed under the impurity separator and the sorting device for shipping impurities and potatoes, respectively. To automatically maintain the minimum distance between

the receiving side of the movable bottom 3 and the unloading platform of the vehicle (to ensure the minimum height of the fall of potatoes), the support under the receiving side of the movable bottom

0, the possibility of changing its size in height is associated with a height sensor 11 mounted on the frame of the receiving part of the movable bottom.

The potato assortment point before5 is assigned to the post-harvest part-time processing of potatoes during storage for storage and works as follows.

The receiving side of the movable bottom 3 with the help of height-adjustable support 4 is brought under the loading platform of the vehicle / ready for unloading of potatoes. When unloading as the loading platform tilts, the height of its output part also changes, which fixes

5, the sensor 11 is height and sends a signal to the support 4 which varies in height. This ensures that the minimum height of the fall of the potatoes from the vehicle to the movable bottom of the bunker is maintained. Potatoes

0 in bulk, unloaded onto the movable bottom 4 of the receiving bunker has a different layer height, but as it advances on the movable bottom it encounters an interlocking leveler 5 (Fig. 3), which flattens

5 potatoes across the entire width of the movable bottom and is adjusted to a certain resistance force, beyond which the pantipodal leveler is moved by the load in the direction of transport with an increase in the passage clearance for the load.

Behind the potato spreader, the potato layer turns out to be the same in cross section and goes to the cargo flow controller 6 (Fig. 4).

5 The cargo flow regulator is designed for the passage of a layer of potatoes of a certain thickness, above which the potato moves the damper with the sensor 7, as a result of which a signal is received to change the speed of transport of potatoes by the movable bottom, the potato feed decreases, the potato layer passing through the cargo flow regulator decreases and the flap returns to its original position.

five

Having passed the cargo flow regulator, the potatoes get on the 8 impurities separator with a uniform, even layer across the entire width of its working part, which ensures high-quality cleaning of impurities from it,

After separators of impurities, the potato gets on the sorting device 9 also in an equal, uniform layer, which will provide a more accurate sorting of potatoes.

Shipping conveyors 10, which are under the impurity separator and the sorting device, ship the impurities and potatoes, respectively, to the container.
