Abstract

This invention relates to a transport engineering industry and allows for improving the quality of sorting of root-and-vegetable crops by quality by stabilizing the interval between adjacent root-and-vegetable crops. The installation includes successively installed devices 1 for orienting root crops in a row, feeding conveyor (K) 2, transmitting K 3 to increase the intervals between root crops, having a greater speed than K 2, and a pitched surface (SP) 4, made in the form of inclined longitudinally belt grooves moving in the opposite direction relative to K 3. Behind SP 4, there is an actuator 14 for transferring the root crops to the outlet K 15, 16. Above the SP 4 is an analyzing system 13 connected to the mechanism 14. A device for separating the root crops located at the exit K 3 is located above the K 3 electromagnetic drum (B) 9, placed at the entrance K 3 of the rotary tray 6 with a counterweight 7 and with an emphasis 8 installed between B 9 and the tray 6 of the return chute 10 and technological dividers 5. The latter are made of a magnet with a soft material. The root crops orient themselves on the device 1 in a row, are fed to K 2 and from there to K 3, which has a greater speed than K 2. The root crops fall on K 3 and the spacing between them is increased, into which separators 5 are supplied from the tray 6, which prevent convergence root crops. The dividers 5 are gripped by B 9 and returned to K 3 through the chute 10, tray 6, to the circular between the latter. Roots are fed to SP 4, slid down over it and rotate due to the counter-displacement of the latter. From system 13, the signal is fed to mechanism 14, which, depending on the quality of the root and tuber crops, supplies them to K 15 or 16. 1 sludge.

The invention relates to agricultural machinery and can be used for sorting of root crops, such as potatoes, at post-harvest processing points.

The purpose of the invention is to improve the accuracy of sorting of root and tuber crops by quality by stabilizing the interval between sedentary root and tuber crops.

The drawing shows schematically an apparatus for sorting root and tuber crops.

The root and shrub screening unit contains successively installed device 1 for orienting root and shrub crops into a row, feeding conveyor 2, feeding the root fruits and vegetables, transmitting conveyor 3 to increase the intervals between the roots, which has a drive (not shown) for telling it a speed greater than the speed of movement feed conveyor 2 and pitched surface 4.

The installation also contains a device for separating root and tuber crops, including movable technological dividers 5 of root and tuber crops, identical in shape to sortable root and tuber crops and made of a soft material magnet — a turning tray 6 for dumping technological dividers, equipped with a counterweight 7 and an emphasis 8, a rotating electromagnetic drum 9 for removing technological separators from conveyor 3 to increase the interval between root and tubers, return chute 10 for removing technological separators from the electromagnetic drum 9 and returning them to the rotary chute 6. The conveyor system, consisting of the drum 9, the chute 10 and the tray b, serves for the continuous and uniform feeding and removal of the technological separators 5, i.e. for their circulation. Tray 6 is located above the entrance of the conveyor 3, and the drum 9 - above its exit. The installation contains a quality control zone 11 of the root crops, above which are installed illuminators 12 of complex spectral composition, analyzing the system 13, consisting of a group of sensors installed across the ramp surface, the separation actuator 14, made in the form of guide pushers arranged successively across the ramp width, retraction conveyor belts 15 and 16, respectively, for poor quality and good fruit. Each sensor of the analyzing system 13 is electrically connected with the corresponding pusher of the actuator 14 and their number is the same.

The movable longitudinal guides of the pitched surface 4 are

belt grooves are intended both for feeding fruit into zone 11 of the monitoring system 13 and into the working zone of the actuator 14, and for rotating the root and tuber crops in order to revise the entire surface, i.e. to increase the accuracy of defect detection. For this, the movable longitudinal guides are set at an angle chosen as follows. to root crops intensively rolled

5 down, and the direction of movement of the longitudinal guide belts is chosen opposite to the direction of feeding of the root and tuber crops and the conveyor 3,

Installation for sorting Korneklub0 non-fruit works as follows.

The potato mass to be sorted is fed by a device for orienting the root and tuber crops to the feeding conveyor 2.

5 the width of the feeding conveyor 2 tubers flow in a single-layer mass to the transmitting conveyor 3 to increase the intervals between the roots and tubers, which creates a gap between tubers due to the difference in transfer speeds, which is caused by the mode of operation of the analyzing system 13 and the actuator 14.

During the intervals between the tubers, the process dividers 5 falling from the overturning tray 6 fall, preventing the tuber from approaching under the action of vibration as it moves along the conveyor 3 to increase the interval, i.e. technological

0 separators reduce the percentage of twins. Immediately before the gathering of the tubers from the conveyor 3, the process dividers 5 enter the magnetic field of the electromagnetic bar 5, are attracted to it and, due to its rotation, are removed from the conveyor 3 and fall on the return chute 10. Rolling off the process dividers fall one by one into the turning tray b.

As long as tray b is not filled with process dividers, it rests against stop 8. Under the action of the counterweight 7, after filling tray 6 it passes through a state of unstable equilibrium, quickly turns over and resets process dividers 5 to conveyor 3, the valve associated with the tray does not allow process dividers to flow from return chute 10 into

Tray 6. After resetting, Tray 6 returns to its original state, the flap opens, and it is again ready to receive the next process separators coming from the chute 10.

The tubers that are already freed at the end of the movement along the conveyor 3 from the technological dividers are flushed to the pitched surface 4, where, due to the oncoming movement of the tape ducts, the tubers are spun active, which ensures their repeated rotation in the control zone, and hence more complete inspection of their surface

Hitting the control zone 11, illuminated by a stream of complex spectral composition from illuminators 12, rotating tubers are individually analyzed in a row by system 13. The signal about substandard tuber comes from a sensor controlling a certain row to the corresponding follower of the actuator 14, which beats off substandard tubers and impurities on the discharge conveyor 15 substandard products. Healthy tubers, loose pads, enter the conveyor 16
